138032Speter SENDMAIL RELEASE NOTES 2249729Sgshapiro $Id: RELEASE_NOTES,v 8.2024 2013/04/19 15:01:58 ca Exp $ 338032Speter 438032Speter 538032SpeterThis listing shows the version of the sendmail binary, the version 638032Speterof the sendmail configuration files, the date of release, and a 738032Spetersummary of the changes in that release. 838032Speter 9249729Sgshapiro8.14.7/8.14.7 2013/04/21 10249729Sgshapiro Drop support for IPv4-mapped IPv6 addresses to prevent the MTA 11249729Sgshapiro from using a mapped address over a legitimate IPv6 address 12249729Sgshapiro and to enforce the proper semantics over the IPv6 13249729Sgshapiro connection. Problem noted by Ulrich Sporlein. 14249729Sgshapiro Fix a regression introduced in 8.14.6: the wrong list of 15249729Sgshapiro macros was sent to a milter in the EHLO stage. 16249729Sgshapiro Problem found by Fabrice Bellet, reported via RedHat 17249729Sgshapiro (Jaroslav Skarvada). 18249729Sgshapiro Fix handling of ORCPT parameter for DSNs: xtext decoding 19249729Sgshapiro was not performed and a wrong syntax check was applied 20249729Sgshapiro to the "addr-type" field. Problem noted by Dan Lukes 21249729Sgshapiro of Obludarium. 22249729Sgshapiro Fix handling of NUL characters in the MIME conversion functions 23249729Sgshapiro so that message bodies containing them will be sent 24249729Sgshapiro on properly. Note: this usually also affects mails 25249729Sgshapiro that are not converted as those functions are used 26249729Sgshapiro for other purposes too. Problem noted by Elchonon 27249729Sgshapiro Edelson of Lockheed Martin. 28249729Sgshapiro Do not perform "duplicate" elimination of recipients if they 29249729Sgshapiro resolve to the error mailer using a temporary failure 30249729Sgshapiro (4xy) via ruleset 0. Problem noted by Akira Takahashi 31249729Sgshapiro of IIJ. 32249729Sgshapiro CONTRIB: Updated version of etrn.pl script from John Beck 33249729Sgshapiro of Oracle. 34249729Sgshapiro Portability: 35249729Sgshapiro Unlike gcc, clang doesn't apply full prototypes to K&R 36249729Sgshapiro definitions. 37249729Sgshapiro 38244833Sgshapiro8.14.6/8.14.6 2012/12/23 39244833Sgshapiro Fix a regression introduced in 8.14.5: if a server offers 40244833Sgshapiro two AUTH lines, the MTA would not read them after 41244833Sgshapiro STARTTLS has been used and hence SMTP AUTH for 42244833Sgshapiro the client side would fail. Problem noted by Lena. 43244833Sgshapiro Do not cache hostnames internally in a non case sensitive way 44244833Sgshapiro as that may cause addresses to change from lower case 45244833Sgshapiro to upper case or vice versa. These header modifications 46244833Sgshapiro can cause problems with milters that rely on receiving 47244833Sgshapiro headers in the same way as they are being sent out such 48244833Sgshapiro as a DKIM signing milter. 49244833Sgshapiro If MaxQueueChildren is set then it was possible that new queue 50244833Sgshapiro runners could not be started anymore because an 51244833Sgshapiro internal counter was subject to a race condition. 52244833Sgshapiro If a milter decreases the timeout it waits for a communication 53244833Sgshapiro with the MTA, the MTA might experience a write() timeout. 54244833Sgshapiro In some situations, the resulting error might have been 55244833Sgshapiro ignored. Problem noted by Werner Wiethege. 56244833Sgshapiro Note: decreasing the communication timeout in a milter 57244833Sgshapiro should not be done without considering the potential 58244833Sgshapiro problems. 59244833Sgshapiro smfi_setsymlist() now properly sets the list of macros for 60244833Sgshapiro the milter which invoked it, instead of a global 61244833Sgshapiro list for all milters. Problem reported by 62244833Sgshapiro David Shrimpton of the University of Queensland. 63244833Sgshapiro If Timeout.resolver.retrans is set to a value larger than 20, 64244833Sgshapiro then resolver.retry was temporarily set to 0 for 65244833Sgshapiro gethostbyaddr() lookups. Now it is set to 1 instead. 66244833Sgshapiro Patch from Peter. 67244833Sgshapiro If sendmail could not lock the statistics file due to a system 68244833Sgshapiro error, and sendmail later sends a DSN for a mail that 69244833Sgshapiro triggered such an error, then sendmail tried to access 70244833Sgshapiro memory that was freed before (causing a crash on some 71244833Sgshapiro systems). Problem reported by Ryan Stone. 72244833Sgshapiro Do not log negative values for size= nor pri= to avoid confusing 73244833Sgshapiro log parsers, instead limit the values to LONG_MAX. 74244833Sgshapiro Account for an API change in newer versions of Cyrus-SASL. 75244833Sgshapiro Patch from Hajimu UMEMOTO from FreeBSD. 76244833Sgshapiro Do not try to resolve link-local addresses for IPv4 (just as it 77244833Sgshapiro is done for IPv6). Patch from John Beck of Oracle. 78244833Sgshapiro Improve logging of client and server STARTTLS connection failures 79244833Sgshapiro that may be due to incompatible cipher lists by including 80244833Sgshapiro the reason for the failure in a single log line. Suggested 81244833Sgshapiro by James Carey of Boeing. 82244833Sgshapiro Portability: 83244833Sgshapiro Add support for Darwin 11.x and 12.x (Mac OS X 10.7 and 10.8). 84244833Sgshapiro Add support for SunOS 5.12 (aka Solaris 12). Patch from 85244833Sgshapiro John Beck of Oracle. 86244833Sgshapiro 87223067Sgshapiro8.14.5/8.14.5 2011/05/17 88223067Sgshapiro Do not cache SMTP extensions across connections as the cache 89223067Sgshapiro is based on hostname which may not be a unique identifier 90223067Sgshapiro for a server, i.e., different machines may have the 91223067Sgshapiro same hostname but provide different SMTP extensions. 92223067Sgshapiro Problem noted by Jim Hermann. 93223067Sgshapiro Avoid an out-of-bounds access in case a resolver reply for a DNS 94223067Sgshapiro map lookup returns a size larger than 1K. Based on a 95223067Sgshapiro patch from Dr. Werner Fink of SuSE. 96223067Sgshapiro If a job is aborted using the interrupt signal (e.g., control-C from 97223067Sgshapiro the keyboard), perform minimal cleanup to avoid invoking 98223067Sgshapiro functions that are not signal-safe. Note: in previous 99223067Sgshapiro versions the mail might have been queued up already 100223067Sgshapiro and would be delivered subsequently, now an interrupt 101223067Sgshapiro will always remove the queue files and thus prevent 102223067Sgshapiro delivery. 103223067Sgshapiro Per RFC 6176, when operating as a TLS client, do not offer SSLv2. 104223067Sgshapiro Since TLS session resumption is never used as a client, disable 105223067Sgshapiro use of RFC 4507-style session tickets. 106223067Sgshapiro Work around gcc4 versions which reverse 25 years of history and 107223067Sgshapiro no longer align char buffers on the stack, breaking calls 108223067Sgshapiro to resolver functions on strict alignment platforms. 109223067Sgshapiro Found by Stuart Henderson of OpenBSD. 110223067Sgshapiro Read at most two AUTH lines from a server greeting (up to two 111223067Sgshapiro lines are read because servers may use "AUTH mechs" and 112223067Sgshapiro "AUTH=mechs"). Otherwise a malicious server may exhaust 113223067Sgshapiro the memory of the client. Bug report by Nils of MWR 114223067Sgshapiro InfoSecurity. 115223067Sgshapiro Avoid triggering an assertion in the OpenLDAP code when the 116223067Sgshapiro connection to an LDAP server is lost while making a query. 117223067Sgshapiro Problem noted and patch provided by Andy Fiddaman. 118223067Sgshapiro If ConnectOnlyTo is set and sendmail is compiled with NETINET6 119223067Sgshapiro it would try to use an IPv6 address if an IPv4 (or 120223067Sgshapiro unparseable) address is specified. 121223067Sgshapiro If SASLv2 is used, make sure that the macro {auth_authen} is 122223067Sgshapiro stored in xtext format to avoid problems with parsing 123223067Sgshapiro it. Problem noted by Christophe Wolfhugel. 124223067Sgshapiro CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing 125223067Sgshapiro -T<TMPF> that is required, but failed for some cases 126223067Sgshapiro that did not use LDAP. This change has been undone 127223067Sgshapiro until a better solution can be implemented. Problem 128223067Sgshapiro found by Andy Fiddaman. 129223067Sgshapiro CONFIG: Add cf/ostype/solaris11.m4 for Solaris11 support. 130223067Sgshapiro Contributed by Casper Dik of Oracle. 131223067Sgshapiro CONTRIB: qtool.pl: Deal with H entries that do not have a 132223067Sgshapiro letter between the question marks. Patch from 133223067Sgshapiro Stefan Christensen. 134223067Sgshapiro DOC: Use a better description for the -i option in sendmail. 135223067Sgshapiro Patch from Mitchell Berger. 136223067Sgshapiro Portability: 137223067Sgshapiro Add support for Darwin 10.x (Mac OS X 10.6). 138223067Sgshapiro Enable HAVE_NANOSLEEP for FreeBSD 3 and later. Patch 139223067Sgshapiro from John Marshall. 140223067Sgshapiro Enable HAVE_NANOSLEEP for OpenBSD 4.3 and later. 141223067Sgshapiro Use new directory "/system/volatile" for PidFile on 142223067Sgshapiro Solaris 11. Patch from Casper Dik of Oracle. 143223067Sgshapiro Fix compilation on Solaris 11 (and maybe some other 144223067Sgshapiro OSs) when using OpenSSL 1.0. Based on patch from 145223067Sgshapiro Jan Pechanec of Oracle. 146223067Sgshapiro Set SOCKADDR_LEN_T and SOCKOPT_LEN_T to socklen_t 147223067Sgshapiro for Solaris 11. Patch from Roger Faulkner of Oracle. 148223067Sgshapiro New Files: 149223067Sgshapiro cf/ostype/solaris11.m4 150223067Sgshapiro 151203004Sgshapiro8.14.4/8.14.4 2009/12/30 152203004Sgshapiro SECURITY: Handle bogus certificates containing NUL characters 153203004Sgshapiro in CNs by placing a string indicating a bad certificate 154203004Sgshapiro in the {cn_subject} or {cn_issuer} macro. Patch inspired 155203004Sgshapiro by Matthias Andree's changes for fetchmail. 156203004Sgshapiro During the generation of a queue identifier an integer overflow 157203004Sgshapiro could occur which might result in bogus characters 158203004Sgshapiro being used. Based on patch from John Vannoy of 159203004Sgshapiro Pepperdine University. 160203004Sgshapiro The value of headers, e.g., Precedence, Content-Type, et.al., 161203004Sgshapiro was not processed correctly. Patch from Per Hedeland. 162203004Sgshapiro Between 8.11.7 and 8.12.0 the length limitation on a return 163203004Sgshapiro path was erroneously reduced from MAXNAME (256) to 164203004Sgshapiro MAXSHORTSTR (203). Patch from John Gardiner Myers 165203004Sgshapiro of Proofpoint; the problem was also noted by Steve 166203004Sgshapiro Hubert of University of Washington. 167203004Sgshapiro Prevent a crash when a hostname lookup returns a seemingly 168203004Sgshapiro valid result which contains a NULL pointer (this seems 169203004Sgshapiro to be happening on some Linux versions). 170203004Sgshapiro The process title was missing the current load average when 171203004Sgshapiro the MTA was delaying connections due to DelayLA. 172203004Sgshapiro Patch from Dick St.Peters of NetHeaven. 173203004Sgshapiro Do not reset the number of queue entries in shared memory if 174203004Sgshapiro only some of them are processed. 175203004Sgshapiro Fix overflow of an internal array when parsing some replies 176203004Sgshapiro from a milter. Problem found by Scott Rotondo 177203004Sgshapiro of Sun Microsystems. 178203004Sgshapiro If STARTTLS is turned off in the server (via M=S) then it 179203004Sgshapiro would not be initialized for use in the client either. 180203004Sgshapiro Patch from Kazuteru Okahashi of IIJ. 181203004Sgshapiro If a Diffie-Hellman cipher is selected for STARTTLS, the 182203004Sgshapiro handshake could fail with some TLS implementations 183203004Sgshapiro because the prime used by the server is not long enough. 184203004Sgshapiro Note: the initialization of the DSA/DH parameters for 185203004Sgshapiro the server can take a significant amount of time on slow 186203004Sgshapiro machines. This can be turned off by setting DHParameters 187203004Sgshapiro to none or a file (see doc/op/op.me). Patch from 188203004Sgshapiro Petr Lampa of the Brno University of Technology. 189203004Sgshapiro Fix handling of `b' modifier for DaemonPortOptions on little 190203004Sgshapiro endian machines for loopback address. Patch from 191203004Sgshapiro John Beck of Sun Microsystems. 192203004Sgshapiro Fix a potential memory leak in libsmdb/smdb1.c found by parfait. 193203004Sgshapiro Based on patch from Jonathan Gray of OpenBSD. 194203004Sgshapiro If a milter sets the reply code to "421" during the transfer 195203004Sgshapiro of the body, the SMTP server will terminate the SMTP session 196203004Sgshapiro with that error to match the behavior of the other callbacks. 197203004Sgshapiro Return EX_IOERR (instead of 0) if a mail submission fails due to 198203004Sgshapiro missing disk space in the mail queue. Based on patch 199203004Sgshapiro from Martin Poole of RedHat. 200203004Sgshapiro CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would 201203004Sgshapiro cause addresses not found in LDAP to be misparsed. 202203004Sgshapiro CONFIG: Using a CN restriction did not work for TLS_Clt as it 203203004Sgshapiro referred to a wrong macro. Patch from John Gardiner 204203004Sgshapiro Myers of Proofpoint. 205203004Sgshapiro CONFIG: The option relaytofulladdress of FEATURE(`access_db') 206203004Sgshapiro did not work if FEATURE(`relay_hosts_only') is used too. 207203004Sgshapiro Problem noted by Kristian Shaw. 208203004Sgshapiro CONFIG: The internal function lower() was broken and hence 209203004Sgshapiro strcasecmp() did not work either, which could cause 210203004Sgshapiro problems for some FEATURE()s if upper case arguments 211203004Sgshapiro were used. Patch from Vesa-Matti J Kari of the 212203004Sgshapiro University of Helsinki. 213203004Sgshapiro LIBMILTER: Fix internal check whether a milter application 214203004Sgshapiro is compiled against the same version of libmilter as 215203004Sgshapiro it is linked against (especially useful for dynamic 216203004Sgshapiro libraries). 217203004Sgshapiro LIBMILTER: Fix memory leak that occurred when smfi_setsymlist() 218203004Sgshapiro was used. Based on patch by Dan Lukes. 219203004Sgshapiro LIBMILTER: Document the effect of SMFIP_HDR_LEADSPC for filters 220203004Sgshapiro which add, insert, or replace headers. From Benjamin 221203004Sgshapiro Pineau. 222203004Sgshapiro LIBMILTER: Fix error messages which refer to "select()" to be 223203004Sgshapiro correct if SM_CONF_POLL is used. Based on patch from 224203004Sgshapiro John Nemeth. 225203004Sgshapiro LIBSM: Fix handling of LDAP search failures where the error is 226203004Sgshapiro carried in the search result itself, such as seen with 227203004Sgshapiro OpenLDAP proxy servers. 228203004Sgshapiro VACATION: Do not refer to a local variable outside its scope. 229203004Sgshapiro Based on patch from Mark Costlow of Southwest Cyberport. 230203004Sgshapiro Portability: 231203004Sgshapiro Enable HAVE_NANOSLEEP for SunOS 5.11. Patch from 232203004Sgshapiro John Beck of Sun Microsystems. 233203004Sgshapiro Drop NISPLUS from default SunOS 5.11 map definitions. 234203004Sgshapiro Patch from John Beck of Sun Microsystems. 235203004Sgshapiro 236182352Sgshapiro8.14.3/8.14.3 2008/05/03 237182352Sgshapiro During ruleset processing the generation of a key for a map 238182352Sgshapiro lookup and the parsing of the default value was broken 239182352Sgshapiro for some macros, e.g., $|, which caused the BlankSub 240182352Sgshapiro character to be inserted into the workspace and thus 241182352Sgshapiro failures, e.g., rules that should have matched did not. 242182352Sgshapiro 8.14.2 caused a regression: it accessed (macro) storage which was 243182352Sgshapiro freed before. First instance of the problem reported by 244182352Sgshapiro Matthew Dillon of DragonFlyBSD; variations of the same 245182352Sgshapiro bug reported by Todd C. Miller of OpenBSD, Moritz 246182352Sgshapiro Jodeit, and Dave Hayes. 247182352Sgshapiro Improve pathname length checks for persistent host status. Patch 248182352Sgshapiro from Joerg Sonnenberger of DragonFlyBSD. 249182352Sgshapiro Reword misleading SMTP reply text for FEATURE(`badmx'). Problem 250182352Sgshapiro noted by Beth Halsema. 251182352Sgshapiro The read timeout was fixed to be Timeout.datablock if STARTTLS 252182352Sgshapiro was activated. This may cause problems if that value 253182352Sgshapiro is lowered from its default. Problem noted by Jens Elkner. 254182352Sgshapiro CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset 255182352Sgshapiro to operate incorrectly. Problem found by Werner Wiethege. 256182352Sgshapiro LIBMILTER: Omitting some protocol steps via the xxfi_negotiate() 257182352Sgshapiro callback did not work properly. The patchlevel of 258182352Sgshapiro libmilter has been set to 1 so a milter can determine 259182352Sgshapiro whether libmilter contains this fix. 260182352Sgshapiro MAKEMAP: If a delimiter is specified (-t) use that also when 261182352Sgshapiro dumping a map. Patch from Todd C. Miller of OpenBSD. 262182352Sgshapiro Portability: 263182352Sgshapiro Add support for Darwin 9.x (Mac OS X 10.5). 264182352Sgshapiro Support shared libraries in Darwin 8 and 9. Patch from 265182352Sgshapiro Chris Behrens of Concentric. 266182352Sgshapiro Add support for SCO OpenServer 6, patch from Boyd Gerber. 267203004Sgshapiro DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing slash. 268182352Sgshapiro Added Files: 269182352Sgshapiro devtools/OS/Darwin.9.x 270182352Sgshapiro devtools/OS/OSR.i386 271182352Sgshapiro 272173340Sgshapiro8.14.2/8.14.2 2007/11/01 273173340Sgshapiro If a message was queued and it contained 8 bit characters in 274173340Sgshapiro a From: or To: header, then those characters could be 275173340Sgshapiro "mistaken" for internal control characters during a queue 276173340Sgshapiro run and trigger various consistency checks. Problem 277173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 278173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 279173340Sgshapiro it is by default) then even if the Linelimit parameter 280173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 281173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 282173340Sgshapiro Myers of Proofpoint. 283173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 284173340Sgshapiro work in earlier 8.14 versions. 285173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 286173340Sgshapiro background if a milter can reject or delete a recipient. 287173340Sgshapiro Prior to 8.14 this happened only if milter could delete 288173340Sgshapiro recipients. 289173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 290182352Sgshapiro documented), not when it was reached. Patch from 291173340Sgshapiro John Beck of Sun Microsystems. 292173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 293173340Sgshapiro specified (R=0) and forking (F=f) is requested. 294173340Sgshapiro When multiple results are requested for a DNS map lookup 295173340Sgshapiro (-z and -Z), return only those that are relevant for 296173340Sgshapiro the query (not also those in the "additional section".) 297173340Sgshapiro If the message transfer time to sendmail (when acting as server) 298173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 299173340Sgshapiro the message is refused (by a milter), sendmail previously 300173340Sgshapiro created a delivery status notification (DSN). Patch 301173340Sgshapiro from Doug Heath of The Hertz Corporation. 302173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 303173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 304173340Sgshapiro Problem noted by Eliot Lear. 305173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 306173340Sgshapiro compiled in but not offered by the server and the 307173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 308173340Sgshapiro If getting the result of an LDAP query times out then close the 309173340Sgshapiro map so it will be reopened on the next lookup. This 310173340Sgshapiro should help "failover" configurations that specify more 311173340Sgshapiro than one LDAP server. 312173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 313173340Sgshapiro be triggered under some circumstances (e.g., requiring 314173340Sgshapiro a system which does not have the compile time flag 315173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 316173340Sgshapiro of National Institute of Informatics, Japan. 317173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 318173340Sgshapiro logfile entry might have been wrong. Problem found by 319173340Sgshapiro Petra Humann of TU Dresden. 320173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 321173340Sgshapiro NULL, the message body was lost. Patch from Motonori 322173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 323173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 324173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 325173340Sgshapiro replacing files. 326173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 327173340Sgshapiro reading the /etc/mail/virtusers/ directory. 328173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 329173340Sgshapiro appropriate. 330173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 331173340Sgshapiro against an older libmilter.so shared library can use an 332173340Sgshapiro 8.14 libmilter.so shared library. 333173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 334173340Sgshapiro from the version number, however, the returned value was 335173340Sgshapiro correct for the current libmilter version. 336173340Sgshapiro 337168515Sgshapiro8.14.1/8.14.1 2007/04/03 338168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 339168515Sgshapiro it in its list of recipients and deliver to it if the 340168515Sgshapiro transaction is accepted. This is a regression introduced 341168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 342168515Sgshapiro found by Andy Fiddaman. 343168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 344168515Sgshapiro could not be set in 8.14.0. 345168515Sgshapiro If a server shut down the connection in response to a STARTTLS 346168515Sgshapiro command, sendmail would log a misleading error message 347168515Sgshapiro due to an internal inconsistency. Problem found by 348168515Sgshapiro Werner Wiethege. 349168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 350168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 351168515Sgshapiro Science and Mathematics. 352168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 353168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 354168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 355168515Sgshapiro m4 options for setting MaxNOOPCommands and 356168515Sgshapiro SharedMemoryKeyFile. 357168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 358168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 359168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 360168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 361168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 362168515Sgshapiro currently available macros.

Notes: 385168515Sgshapiro - header field names are still restricted to 7 bit. 386168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 387168515Sgshapiro headers. 388168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 389168515Sgshapiro number of spaces after the colon would be changed to 390168515Sgshapiro exactly one space. 391168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 392168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 393168515Sgshapiro limit may be reached too early, e.g., the counter 394168515Sgshapiro may be off by a factor of 4 in case of a sequence of 395168515Sgshapiro .forward files that refer to others. Patch from 396168515Sgshapiro Motonori Nakamura of Kyoto University. 397168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 398168515Sgshapiro "sendmail -bs" can trigger an assertion because the 399168515Sgshapiro hostname of the client is undefined. It is now set 400168515Sgshapiro to "localhost" for the xxfi_connect() callback. 401168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 402168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 403168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 404168515Sgshapiro Patch from Nik Clayton. 405168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 406168515Sgshapiro permanent errors (5xy). This can be useful for testing. 407168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 408168515Sgshapiro per daemon socket: 409168515Sgshapiro DeliveryMode DeliveryMode 410168515Sgshapiro refuseLA RefuseLA 411168515Sgshapiro delayLA DelayLA 412168515Sgshapiro queueLA QueueLA 413168515Sgshapiro children MaxDaemonChildren 414168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 415168515Sgshapiro lookup key with the LDAP escaped contents of the 416168515Sgshapiro arguments specified in the map lookup. Loosely based 417168515Sgshapiro on patch from Wolfgang Hottgenroth. 418168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 419168515Sgshapiro from Nik Clayton. 420168515Sgshapiro If a client is rejected via TCP wrapper or some other check 421168515Sgshapiro performed by validate_connection() (in conf.c) then do 422168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 423168515Sgshapiro of the University of Illinois at Urbana-Champaign. 424168515Sgshapiro If a client terminates the SMTP connection during a pause 425168515Sgshapiro introduced by greet_pause, then a misleading message 426168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 427168515Sgshapiro et.al., patch from Matej Vela. 428168515Sgshapiro New command "mstat" for control socket to provide "machine 429168515Sgshapiro readable" status. 430168515Sgshapiro New named config file rule check_eom which is called at the end 431168515Sgshapiro of a message, its parameter is the size of the message. 432168515Sgshapiro If the macro {addr_type} indicates that the current address 433168515Sgshapiro is a header address it also distinguishes between 434168515Sgshapiro recipient and sender addresses (as it is done for 435168515Sgshapiro envelope addresses). 436168515Sgshapiro When a macro is set in check_relay, then its value is accessible 437168515Sgshapiro by all transactions in the same SMTP session. 438168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 439168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 440168515Sgshapiro number of "useless" commands before the SMTP server will 441168515Sgshapiro slow down responding. 442168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 443168515Sgshapiro enabled, the MTA can be asked to select a shared memory 444168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 445168515Sgshapiro a file where to store the selected key. 446168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 447168515Sgshapiro by recognizing some commands from them. If the first command 448168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 449168515Sgshapiro connection is terminated immediately. 450168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 451168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 452168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 453168515Sgshapiro New options B, z, and Z for DNS maps: 454168515Sgshapiro -B: specify a domain that is always appended to queries. 455168515Sgshapiro -z: specify the delimiter at which to cut off the result of 456168515Sgshapiro a query if it is too long. 457168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 458168515Sgshapiro to form the result of a lookup. 459168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 460168515Sgshapiro implicitly while building libsm, they must be explicitly 461168515Sgshapiro started by using "make check". 462168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 463168515Sgshapiro reported by the SATURN tool which has been developed by 464168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 465168515Sgshapiro Fix a potential race condition caused by a signal handler for 466168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 467168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 468168515Sgshapiro queue group selection. This has been disabled as it was not 469168515Sgshapiro intended. 470168515Sgshapiro New operator 'r' for the arith map to return a random number. 471168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 472168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 473168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 474168515Sgshapiro which may improve the communication performance on some 475168515Sgshapiro operating systems. Patch from John Gardiner Myers of 476168515Sgshapiro Proofpoint. 477168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 478168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 479168515Sgshapiro generate an additional blank line in the output as the last 480168515Sgshapiro line. 481168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 482168515Sgshapiro the "queue control process" (QCP) works now. 483168515Sgshapiro Increase the length of an input line to 12288 to deal with 484168515Sgshapiro really long lines during SMTP AUTH negotiations. 485168515Sgshapiro Problem noted by Werner Wiethege. 486168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 487168515Sgshapiro a missing initialization call for that case). Problem 488168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 489168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 490168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 491168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 492168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 493168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 494168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 495168515Sgshapiro the MTA will not attempt to open a statistics file on 496168515Sgshapiro each delivery. 497168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 498168515Sgshapiro clients whose IP address does not have proper reverse DNS. 499168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 500168515Sgshapiro and John Beck of Sun Microsystems. 501168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 502168515Sgshapiro clients which provide a HELO/EHLO argument which is either 503168515Sgshapiro unqualified, or is one of our own names (i.e., the server 504168515Sgshapiro name instead of the client name). Contributed by Neil 505168515Sgshapiro Rickert of Northern Illinois University and John Beck of 506168515Sgshapiro Sun Microsystems. 507168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 508168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 509168515Sgshapiro Based on contribution from William Dell Wisner. 510168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 511168515Sgshapiro the maximum line length of the smtp mailers. 512168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 513168515Sgshapiro to allow entries in the access map to be of the form 514168515Sgshapiro To:user@example.com RELAY 515168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 516168515Sgshapiro macros a milter should receive at those stages in the 517168515Sgshapiro SMTP dialogue. 518168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 519168515Sgshapiro for the HELO/EHLO command. 520168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 521168515Sgshapiro messages by using those values as second argument. 522168515Sgshapiro Patches from Nelson Fung. 523168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 524168515Sgshapiro ignores everything after it unless it is in quotes or 525168515Sgshapiro preceeded by a backslash. 526168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 527168515Sgshapiro directories, then it used for "make install" to create 528168515Sgshapiro the required installation directories. 529168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 530168515Sgshapiro executables (defaults to confCC). 531168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 532168515Sgshapiro has several changes which are listed below and documented 533168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 534168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 535168515Sgshapiro changed. It now refers only to the version of libmilter, 536168515Sgshapiro not to the protocol version (which is used only internally, 537168515Sgshapiro it is not user/milter-programmer visible). Additionally, 538168515Sgshapiro a version function smfi_version() has been introduced such 539168515Sgshapiro that a milter program can check the libmilter version also 540168515Sgshapiro at runtime which is useful if a shared library is used. 541168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 542168515Sgshapiro dynamically (i.e., at runtime) determine the available 543168515Sgshapiro protocol actions and features of the MTA and also to 544168515Sgshapiro specify which of these a milter wants to use. This allows 545168515Sgshapiro for more flexibility than hardcoding these flags in the 546168515Sgshapiro xxfi_flags field of the smfiDesc structure. 547168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 548168515Sgshapiro can act on the DATA command. 549168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 550168515Sgshapiro can receive also unknown SMTP commands. 551168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 552168515Sgshapiro can be used by the xxfi_header() callback provided the 553168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 554168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 555168515Sgshapiro xxfi_body() callback to skip over further body chunks 556168515Sgshapiro and directly advance to the xxfi_eom() callback. This 557168515Sgshapiro is useful if a milter can make a decision based on the 558168515Sgshapiro body chunks it already received without reading the entire 559168515Sgshapiro rest of the body and the milter wants to invoke functions 560168515Sgshapiro that are only available from the xxfi_eom() callback. 561168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 562168515Sgshapiro new recipients including ESMTP parameters. 563168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 564168515Sgshapiro envelope sender including ESMTP parameters. 565168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 566168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 567168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 568168515Sgshapiro a RCPT has been rejected can be checked by comparing the 569168515Sgshapiro value of the macro {rcpt_mailer} with "error". 570168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 571168515Sgshapiro wants to receive from the MTA for each protocol step 572168515Sgshapiro by invoking the function smfi_setsymlist() during option 573168515Sgshapiro negotiation. 574168515Sgshapiro LIBMILTER: A milter can receive header field values with all 575168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 576168515Sgshapiro protocol action. Also, if the flag is set then the MTA 577168515Sgshapiro does not add a leading space to headers that are added, 578168515Sgshapiro inserted, or replaced. 579168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 580168515Sgshapiro callback, the SMTP server will terminate the SMTP session 581168515Sgshapiro with that error to match the behavior of all other callbacks. 582168515Sgshapiro New Files: 583168515Sgshapiro cf/feature/badmx.m4 584168515Sgshapiro cf/feature/block_bad_helo.m4 585168515Sgshapiro cf/feature/require_rdns.m4 586168515Sgshapiro devtools/M4/UNIX/check.m4 587168515Sgshapiro include/sm/misc.h 588168515Sgshapiro include/sm/sendmail.h 589168515Sgshapiro include/sm/tailq.h 590168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 591168515Sgshapiro libmilter/docs/smfi_setsymlist.html 592168515Sgshapiro libmilter/docs/xxfi_data.html 593168515Sgshapiro libmilter/docs/xxfi_negotiate.html 594168515Sgshapiro libmilter/docs/xxfi_unknown.html 595168515Sgshapiro libmilter/example.c 596168515Sgshapiro libmilter/monitor.c 597168515Sgshapiro libmilter/worker.c 598168515Sgshapiro libsm/memstat.c 599168515Sgshapiro libsm/t-memstat.c 600168515Sgshapiro libsm/t-qic.c 601168515Sgshapiro libsm/util.c 602168515Sgshapiro sendmail/daemon.h 603168515Sgshapiro sendmail/map.h 604168515Sgshapiro 605161389Sgshapiro8.13.8/8.13.8 2006/08/09 606161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 607161389Sgshapiro the server can erroneously report that there is 608161389Sgshapiro insufficient disk space. Additionally make sure that 609161389Sgshapiro an internal variable is set properly to avoid those 610161389Sgshapiro misleading errors. Based on patch from Steve Hubert 611161389Sgshapiro of University of Washington. 612161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 613161389Sgshapiro the process that forks the daemon exited, i.e., if 614161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 615161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 616161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 617161389Sgshapiro David F.

However, 624161389Sgshapiro this did not match the documentation of the function, hence 625161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 626161389Sgshapiro about these macros. 627161389Sgshapiro 628159609Sgshapiro8.13.7/8.13.7 2006/06/14 629159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 630159609Sgshapiro crash while trying to send a mail due to a stack overflow, 631159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 632159609Sgshapiro happens because the recursion of the function mime8to7() 633159609Sgshapiro was not restricted. The function is called for MIME 8 to 634159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 635159609Sgshapiro To work around this problem, recursive calls are limited to 636159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 637159609Sgshapiro limit is treated as opaque and is not checked further. 638159609Sgshapiro Problem noted by Frank Sheiness. 639159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 640159609Sgshapiro SASL mechanisms that use the security layer, e.g., 641159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 642159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 643159609Sgshapiro a df file might have been left behind in the queue. 644159609Sgshapiro This was another side effect of the changes to the I/O 645159609Sgshapiro layer made in 8.13.6. 646159609Sgshapiro Several minor problems have been fixed that were found by a 647159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 648159609Sgshapiro distribution. See http://scan.coverity.com/ 649159609Sgshapiro Note: the scan generated also a lot of "false positives", 650159609Sgshapiro e.g., "error" reports about situations that cannot happen. 651159609Sgshapiro Most of those code places are marked with lint(1) comments 652159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 653159609Sgshapiro Hence an explicit assertion has been added in some cases 654159609Sgshapiro to avoid those false positives. 655159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 656159609Sgshapiro error then in some cases shared memory segments or pid 657159609Sgshapiro files were not removed. 658159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 659159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 660159609Sgshapiro reported by Akihiro Sagawa. 661159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 662159609Sgshapiro bug work-around. Hence if sendmail is linked against 663159609Sgshapiro either of these versions and compression is available, 664159609Sgshapiro the padding bug work-around is turned off. Based on 665159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 666159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 667159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 668159609Sgshapiro however, that list is no longer available. To avoid 669159609Sgshapiro further problems, no default value is available anymore, 670159609Sgshapiro but an argument must be specified. 671159609Sgshapiro Portability: 672159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c. Patch from 673159609Sgshapiro Pieter Bowman of the University of Utah. 674159609Sgshapiro 675157001Sgshapiro8.13.6/8.13.6 2006/03/22 676157001Sgshapiro SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server 677157001Sgshapiro and client side of sendmail with timeouts in the libsm I/O 678157001Sgshapiro layer and fix problems in that code. Also fix handling of 679157001Sgshapiro a buffer in sm_syslog() which could have been used as an 680157001Sgshapiro attack vector to exploit the unsafe handling of 681157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 682157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 683157001Sgshapiro Handle theoretical integer overflows that could triggered if 684157001Sgshapiro the server accepted headers larger than the maximum 685157001Sgshapiro (signed) integer value. This is prevented in the default 686157001Sgshapiro configuration by restricting the size of a header, and on 687157001Sgshapiro most machines memory allocations would fail before reaching 688157001Sgshapiro those values. Problems found by Phil Brass of ISS. 689157001Sgshapiro If a server returns 421 for an RSET command when trying to start 690157001Sgshapiro another transaction in a session while sending mail, do 691157001Sgshapiro not trigger an internal consistency check. Problem found 692157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 693157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 694157001Sgshapiro to a STARTTLS command despite the fact that it advertised 695157001Sgshapiro STARTTLS and that the code is not valid according to RFC 696157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 697157001Sgshapiro of a protocol error (which has been changed to a 698157001Sgshapiro temporary error in 8.13.5). Problem reported by Jeff 699157001Sgshapiro A. Earickson of Colby College. 700157001Sgshapiro Clear SMTP state after a HELO/EHLO command. Patch from John 701157001Sgshapiro Myers of Proofpoint. 702157001Sgshapiro Observe MinQueueAge option when gathering entries from the queue 703157001Sgshapiro for sorting etc instead of waiting until the entries are 704157001Sgshapiro processed. Patch from Brian Fundakowski Feldman. 705157001Sgshapiro Set up TLS session cache to properly handle clients that try to 706157001Sgshapiro resume a stored TLS session. 707157001Sgshapiro Properly count the number of (direct) child processes such that 708157001Sgshapiro a configured value (MaxDaemonChildren) is not exceeded. 709157001Sgshapiro Based on patch from Attila Bruncsak. 710157001Sgshapiro LIBMILTER: Remove superfluous backslash in macro definition 711157001Sgshapiro (libmilter.h). Based on patch from Mike Kupfer of 712157001Sgshapiro Sun Microsystems. 713157001Sgshapiro LIBMILTER: Don't try to set SO_REUSEADDR on UNIX domain sockets. 714157001Sgshapiro This generates an error message from libmilter on 715157001Sgshapiro Solaris, though other systems appear to just discard the 716157001Sgshapiro request silently. 717157001Sgshapiro LIBMILTER: Deal with sigwait(2) implementations that return 718157001Sgshapiro -1 and set errno instead of returning an error code 719157001Sgshapiro directly. Patch from Chris Adams of HiWAAY Informations 720157001Sgshapiro Services. 721157001Sgshapiro Portability: 722157001Sgshapiro Fix compilation checks for closefrom(3) and statvfs(2) 723157001Sgshapiro in NetBSD. Problem noted by S. Moonesamy, patch from 724157001Sgshapiro Andrew Brown. 725157001Sgshapiro 726157001Sgshapiro8.13.5/8.13.5 2005/09/16 727157001Sgshapiro Store the filesystem identifier of the df/ subdirectory (if it 728157001Sgshapiro exists) in an internal structure instead of the base 729157001Sgshapiro directory. This structure is used decide whether there 730157001Sgshapiro is enough free disk space when selecting a queue, hence 731157001Sgshapiro without this change queue selection could fail if a df/ 732157001Sgshapiro subdirectory exists and is on a different filesystem 733157001Sgshapiro than the base directory. 734157001Sgshapiro Use the queue index of the df file (instead of the qf file) for 735157001Sgshapiro checking whether a link(2) operation can be used to split 736157001Sgshapiro an envelope across queue groups. Problem found by 737157001Sgshapiro Werner Wiethege. 738157001Sgshapiro If the list of items in the queue is larger than the maximum 739157001Sgshapiro number of items to process, sort the queue first and 740157001Sgshapiro then cut the list off instead of the other way around. 741157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 742157001Sgshapiro Fix helpfile to show full entry for ETRN. Problem noted by 743157001Sgshapiro Penelope Fudd, patch from Neil Rickert of Northern Illinois 744157001Sgshapiro University. 745157001Sgshapiro FallbackSmartHost should also be tried on temporary errors. 746157001Sgshapiro From John Beck of Sun Microsystems. 747157001Sgshapiro When a server responds with 421 to the STARTTLS command then treat 748157001Sgshapiro it as a temporary error, not as protocol error. Problem 749157001Sgshapiro noted by Andrey J. Melnikoff. 750157001Sgshapiro Properly define two functions in libsm as static because their 751157001Sgshapiro prototype used static too. Patch from Peter Klein. 752157001Sgshapiro Fix syntax errors in helpfile for MAIL and RCPT commands. 753157001Sgshapiro LIBMILTER: When smfi_replacebody() is called with bodylen equals 754157001Sgshapiro zero then do not silently ignore that call. Patch from 755157001Sgshapiro Gurusamy Sarathy of Active State. 756157001Sgshapiro LIBMILTER: Recognize "421" also in a multi-line reply to terminate 757157001Sgshapiro the SMTP session with that error. Fix from Brian Kantor. 758157001Sgshapiro Portability: New option HASSNPRINTF which can be set if the OS 759157001Sgshapiro has a properly working snprintf(3) to get rid 760157001Sgshapiro of the last two (safe) sprintf(3) calls in the 761157001Sgshapiro source code. 762157001Sgshapiro Add support for AIX 5.3. 763157001Sgshapiro Add support for SunOS 5.11 (aka Solaris 11). 764157001Sgshapiro Add support for Darwin 8.x. Patch from Lyndon Nerenberg. 765157001Sgshapiro OpenBSD 3.7 has removed support for NETISO. 766157001Sgshapiro CONFIG: Add OSTYPE(freebsd6) for FreeBSD 6.X. 767157001Sgshapiro Set DontBlameSendmail to AssumeSafeChown and 768157001Sgshapiro GroupWritableDirPathSafe for OSTYPE(darwin). 769157001Sgshapiro Patch from Lyndon Nerenberg. 770157001Sgshapiro Some features still used 4.7.1 as enhanced status code which 771157001Sgshapiro was supposed to be eliminated in 8.13.0 because some 772157001Sgshapiro broken systems misinterpret it as a permanent error. 773157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 774157001Sgshapiro Some default values in a generated cf file did not match 775157001Sgshapiro the defaults in the sendmail binary.

Problem noted by Michael Sims. 789147078Sgshapiro Deal with empty hostnames in hostsignature(). This bug could lead 790147078Sgshapiro to an endless loop when doing LMTP deliveries to another 791147078Sgshapiro host. Problem first reported by Martin Lathoud and 792147078Sgshapiro tracked down by Gael Roualland. 793147078Sgshapiro Make sure return parameters are initialized in getmxrr(). Problem 794147078Sgshapiro found by Gael Roualland using valgrind. 795147078Sgshapiro If shared memory is used and the RunAsUser option is set, then the 796161389Sgshapiro owner and group of the shared memory segment is set to 797147078Sgshapiro the ids specified RunAsUser and the access mode is set 798147078Sgshapiro to 0660 to allow for updates by sendmail processes. 799147078Sgshapiro The number of queue entries that is (optionally) kept in shared 800147078Sgshapiro memory was wrong in some cases, e.g., envelope splitting 801147078Sgshapiro and bounce generation. 802147078Sgshapiro Undo a change made in 8.13.0 to silently truncate long strings 803147078Sgshapiro in address rewriting because the message can be triggered 804147078Sgshapiro for header checks where long strings are legitimate. 805147078Sgshapiro Problem reported by Mary Verge DeSisto, and tracked 806147078Sgshapiro down with the help of John Beck of Sun Microsystems. 807147078Sgshapiro The internal stab map did not obey the -m flag. Patch from 808147078Sgshapiro Rob McMahon of Warwick University, England. 809147078Sgshapiro The socket map did not obey the -f flag. Problem noted by 810147078Sgshapiro Dan Ringdahl, forwarded by Andrzej Filip. 811147078Sgshapiro The addition of LDAP recursion in 8.13.0 broke enforcement of 812147078Sgshapiro the LDAP map -1 argument which tells the MTA to only 813147078Sgshapiro return success if and only if a single LDAP match is found. 814147078Sgshapiro Add additional error checks in the MTA for milter communication 815147078Sgshapiro to avoid a possible segmentation fault. Based on patch 816147078Sgshapiro by Joe Maimon. 817147078Sgshapiro Do not trigger an assertion if X509_digest() returns success but 818147078Sgshapiro does not assign a value to its output parameter.

This prevents bogus "Bad 863141858Sgshapiro file number" recipient status. Problem noted by 864141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 865141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 866141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 867141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 868141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 869141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 870141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 871141858Sgshapiro them off at a comma.

Problem tracked down by Per Hedeland. 941132943Sgshapiro New Files: 942132943Sgshapiro doc/op/README 943132943Sgshapiro 944132943Sgshapiro8.13.0/8.13.0 2004/06/20 945132943Sgshapiro Do not include AUTH data in a bounce to avoid leaking confidential 946132943Sgshapiro information. See also cf/README about MSP and the section 947132943Sgshapiro "Providing SMTP AUTH Data when sendmail acts as Client". 948132943Sgshapiro Problem noted by Neil Rickert of Northern Illinois 949132943Sgshapiro University. 950132943Sgshapiro Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n 951132943Sgshapiro and -DSM_CONF_SETITIMER=0. Problem noted by Juergen Georgi 952132943Sgshapiro of RUS University of Stuttgart. 953132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 954132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 955132943Sgshapiro Add support for LDAP recursion based on types given to attribute 956132943Sgshapiro specifications in an LDAP map definition. This allows 957132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 958132943Sgshapiro URL which will in turn be queried. See the ``LDAP 959132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 960132943Sgshapiro Based on patch from Andrew Baucom. 961132943Sgshapiro Extend the default LDAP specifications for AliasFile 962132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 963132943Sgshapiro include support for LDAP recursion via new attributes. 964132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 965132943Sgshapiro of cf/README for more information. 966132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 967132943Sgshapiro LDAP API/protocol version to use. The default depends on 968132943Sgshapiro the LDAP library. 969132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 970132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 971132943Sgshapiro and -p port. This also allows for the use of LDAP over 972132943Sgshapiro SSL and connections via named sockets if your LDAP 973132943Sgshapiro library supports it. 974132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 975132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 976132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 977132943Sgshapiro during a SMTP session then terminate it just like it is 978132943Sgshapiro done for too many bad SMTP commands. 979132943Sgshapiro Basic connection rate control support has been added: the daemon 980132943Sgshapiro maintains the number of incoming connections per client 981132943Sgshapiro IP address and total in the macros {client_rate} and 982132943Sgshapiro {total_rate}, respectively. These macros can be used 983132943Sgshapiro in the cf file to impose connection rate limits. 984132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 985132943Sgshapiro determines the length of the interval for which the 986132943Sgshapiro number of connections is stored. Based on patch from 987132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 988132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 989132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 990132943Sgshapiro If enabled by the new ruleset greet_pause (see 991132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 992132943Sgshapiro amount of time before sending the initial 220 SMTP 993132943Sgshapiro greeting. If any traffic is received before then, a 554 994132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 995132943Sgshapiro during that connection. 996132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 997132943Sgshapiro server could sleep for a very long time. Fix based on 998132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 999132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 1000132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 1001132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 1002132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 1003132943Sgshapiro misinterpret it as a permanent error. 1004132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 1005132943Sgshapiro all milters accepted the mail. This can increase 1006132943Sgshapiro performance if many mails are rejected by milters due to 1007132943Sgshapiro body scans. Based on patch from David F. Skoll. 1008132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 1009132943Sgshapiro header, whether provided by the client or generated by 1010132943Sgshapiro sendmail. 1011132943Sgshapiro New macro {client_connections} which contains the number of open 1012132943Sgshapiro connections in the SMTP server for the client IP address. 1013132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 1014132943Sgshapiro Mines de Paris. 1015132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 1016132943Sgshapiro to prevent confusion caused by running sendmail stop 1017132943Sgshapiro scripts two or more times, where the second and subsequent 1018141858Sgshapiro runs would report misleading error messages about sendmail's 1019132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 1020132943Sgshapiro for a discussion of the implications of this, including 1021132943Sgshapiro how to correct broken scripts which may have depended on 1022132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 1023132943Sgshapiro Support per-daemon input filter lists which override the default 1024132943Sgshapiro filter list specified in InputMailFilters. The filters 1025132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 1026132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 1027132943Sgshapiro your configuration relies on this behavior, you have to 1028132943Sgshapiro add those names to class 'w' yourself. Problem noted 1029132943Sgshapiro by Sander Eerkes. 1030132943Sgshapiro Support message quarantining in the mail queue. Quarantined 1031132943Sgshapiro messages are not run on normal queue displays or runs 1032132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 1033132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 1034132943Sgshapiro The -q command line option now can specify which queue to display 1035132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 1036132943Sgshapiro operates on lost queue items. 1037132943Sgshapiro Restricted mail queue runs and displays can be done based on the 1038132943Sgshapiro quarantined reason using -qQtext to run or display 1039132943Sgshapiro quarantined items if the quarantine reason contains the 1040132943Sgshapiro given text. Similarly, -q!Qtext will run or display 1041132943Sgshapiro quarantined items which do not have the given text in the 1042132943Sgshapiro quarantine reason. 1043132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 1044132943Sgshapiro new -Q option. See doc/op/op.me for more information. 1045132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 1046132943Sgshapiro quarantine reason is shown in a new line prefixed by 1047132943Sgshapiro "QUARANTINE:". 1048132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 1049132943Sgshapiro to quarantine messages in check_* (except check_compat) and 1050132943Sgshapiro header check rulesets. The $: of the mailer triplet will 1051132943Sgshapiro be used for the quarantine reason. 1052132943Sgshapiro Add a new quarantine count to the mailstats collected. 1053132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 1054132943Sgshapiro message if it is quarantined. 1055132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 1056132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 1057132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 1058132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 1059132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 1060132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 1061132943Sgshapiro lookup for the client IP address. Note: this is the same 1062132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 1063132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 1064132943Sgshapiro recipients received so far in a transaction. 1065132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 1066132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 1067132943Sgshapiro noted by Kai Schlichting. 1068132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 1069132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 1070132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 1071132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 1072132943Sgshapiro Wolfhugel of France Telecom Oleane. 1073132943Sgshapiro Do not silently truncate long strings in address rewriting. 1074132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 1075132943Sgshapiro Oceana Matrix Ltd. 1076132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 1077132943Sgshapiro support mutual authentication. From Kenneth Murchison of 1078132943Sgshapiro Oceana Matrix Ltd. 1079132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 1080132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 1081132943Sgshapiro format just like the STARTTLS related macros to avoid 1082132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 1083132943Sgshapiro Masarati of SysNet s.n.c. 1084132943Sgshapiro New option AuthRealm to set the authentication realm that is 1085132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 1086132943Sgshapiro of the University of Manitoba. 1087132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 1088132943Sgshapiro successful, otherwise relaying would be allowed if 1089132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 1090132943Sgshapiro is active. 1091132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 1092132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 1093132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 1094132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 1095132943Sgshapiro DIGEST-MD5 and LOGIN. 1096132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 1097132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 1098132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 1099132943Sgshapiro overwrite each other's pid files. 1100132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 1101132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 1102132943Sgshapiro Wolfhugel of France Telecom. 1103132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 1104132943Sgshapiro LogLevel 12 or higher. 1105132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 1106132943Sgshapiro try to use the SMTP command VERB to propagate this option 1107132943Sgshapiro to the MTA which in turn will show the delivery just like 1108132943Sgshapiro it was done before the default 8.12 separation of MSP and 1109132943Sgshapiro MTA. Based on patch by Per Hedeland. 1110132943Sgshapiro If a daemon is refusing connections for longer than the time specified 1111132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 1112132943Sgshapiro to high load, log this information. Patch from John Beck 1113132943Sgshapiro of Sun Microsystems. 1114132943Sgshapiro Remove the ability for non-trusted users to raise the value of 1115132943Sgshapiro CheckpointInterval on the command line. 1116132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 1117132943Sgshapiro subset of the functionality of the 's' flag. 1118132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 1119132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 1120132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 1121132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 1122132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 1123132943Sgshapiro causing subsequent messages to be sent instead of being 1124132943Sgshapiro discarded. This also caused milter callbacks to be called 1125132943Sgshapiro out of order after the SMTP session was reset. 1126132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 1127132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 1128132943Sgshapiro further information. 1129132943Sgshapiro New command line option -D logfile to send debug output to 1130132943Sgshapiro the indicated log file instead of stdout. 1131132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 1132132943Sgshapiro queue return and warning times for delivery status 1133132943Sgshapiro notifications. 1134132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 1135132943Sgshapiro at all. 1136132943Sgshapiro Several more return values for ruleset srv_features have been added 1137132943Sgshapiro to enable/disable certain features in the server per 1138132943Sgshapiro connection. See doc/op/op.me for details. 1139132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 1140132943Sgshapiro for DaemonPortOptions. 1141132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 1142132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 1143132943Sgshapiro of Northern Illinois University. 1144132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 1145132943Sgshapiro be tried as a last resort after all other fallbacks. This 1146132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 1147132943Sgshapiro view of inside the company, but an incomplete view of 1148132943Sgshapiro outside). From John Beck of Sun Microsystems. 1149132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 1150132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 1151132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 1152132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 1153132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 1154132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 1155132943Sgshapiro of the University of Illinois at Urbana-Champaign. 1156132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 1157132943Sgshapiro applications for use in the xxfi_eom() callback. 1158132943Sgshapiro New macro {time} which contains the output of the time(3) function, 1159132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 1160132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 1161132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 1162132943Sgshapiro terminate the SMTP session with a 421 error message. 1163132943Sgshapiro Get rid of dead code that tried to access the environment variable 1164132943Sgshapiro HOSTALIASES. 1165132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 1166132943Sgshapiro compile with -DUSE_TTYPATH=1. 1167132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 1168132943Sgshapiro the header value passed in without balancing quotes, 1169132943Sgshapiro parentheses, and angle brackets. Based on patch from 1170132943Sgshapiro Oleg Bulyzhin. 1171132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 1172132943Sgshapiro angle brackets when reading in rulesets. This allows 1173132943Sgshapiro rules to be written for header checks to catch strings 1174132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 1175132943Sgshapiro Based on patch from Oleg Bulyzhin. 1176132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 1177132943Sgshapiro some temporary errors like ECONNABORTED. 1178132943Sgshapiro Added list of CA certificates that are used by members of the 1179132943Sgshapiro sendmail consortium, see CACerts. 1180132943Sgshapiro Portability: 1181132943Sgshapiro Two new compile options have been added: 1182132943Sgshapiro HASCLOSEFROM System has closefrom(3). 1183132943Sgshapiro HASFDWALK System has fdwalk(3). 1184132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 1185132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 1186132943Sgshapiro change to using fcntl() locking until they can fix 1187132943Sgshapiro it. Be sure to update other sendmail related 1188132943Sgshapiro programs to match locking techniques. 1189132943Sgshapiro New compile time option NEEDINTERRNO which should be set 1190132943Sgshapiro if <errno.h> does not declare errno itself. 1191132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 1192132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 1193132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 1194132943Sgshapiro Center for Scientific Computing. 1195132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 1196132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 1197132943Sgshapiro Remove path from compiler definition for Interix because 1198132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 1199132943Sgshapiro Also use <sys/mkdev.h> to get the correct 1200132943Sgshapiro major()/minor() definitions. Based on feedback 1201132943Sgshapiro from Mark Funkenhauser. 1202132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 1203132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 1204132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 1205132943Sgshapiro cf/sendmail.schema for more information. 1206132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 1207132943Sgshapiro is of the form "user:group" when used for submit.mc. 1208132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 1209132943Sgshapiro of Northern Illinois University. 1210132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 1211132943Sgshapiro instructs the check_* (except check_compat) to quarantine 1212132943Sgshapiro the message using the given reason. 1213132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 1214132943Sgshapiro instead of "host" to avoid problem with looking up other 1215132943Sgshapiro DNS records than just A. 1216132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 1217132943Sgshapiro length of the interval for which the number of incoming 1218132943Sgshapiro connections is maintained. 1219132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 1220132943Sgshapiro rate control for individual hosts or nets. 1221132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 1222132943Sgshapiro number of open SMTP connections for individual hosts or nets. 1223132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 1224132943Sgshapiro slamming protection described above. The feature can 1225132943Sgshapiro take an argument specifying the milliseconds to wait and/or 1226132943Sgshapiro use the access database to look the pause time based on 1227132943Sgshapiro client hostname, domain, IP address, or subnet. 1228132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 1229132943Sgshapiro $&{client_ptr} as its first argument.

From Michel Bourget of SGI. 1712102528Sgshapiro Fix compilation issues on Mac OS X 10.2 (Darwin 6.0). 1713102528Sgshapiro NETISO support has been dropped. 1714102528Sgshapiro CONFIG: There was a seemingly minor change in 8.12.4 with respect 1715102528Sgshapiro to handling entries of IP nets/addresses with RHS REJECT. 1716102528Sgshapiro These would be rejected in check_rcpt instead of only 1717102528Sgshapiro being activated in check_relay. This change has been made to 1718102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 1719102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 1720102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1721102528Sgshapiro modification causes a change of behavior if an IP net/address 1722102528Sgshapiro is listed in the access map with REJECT and a host/domain 1723102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1724102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1725102528Sgshapiro change was made on request of Neil Rickert of Northern 1726102528Sgshapiro Illinois University, the side effect has been found by 1727102528Sgshapiro Stefaan Van Hoornick. 1728102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1729102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1730102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1731102528Sgshapiro University. 1732102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1733102528Sgshapiro Fix from Andrzej Filip. 1734102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1735102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1736102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1737102528Sgshapiro NULL pointer.

In previous versions this could cause mail 187494334Sgshapiro not to be delivered if a queue file is repeatedly moved 187594334Sgshapiro by an external process whenever sendmail moved it back 187694334Sgshapiro into the right place. Some precautions have been taken 187794334Sgshapiro to avoid moving queue files if not really necessary. 187894334Sgshapiro sendmail may use links to refer to queue files and it 187994334Sgshapiro may store the path of data files in queue files. Hence 188094334Sgshapiro queue files should not be moved unless those internals 188194334Sgshapiro are understood and the integrity of the files is not 188294334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 188394334Sgshapiro University. 188494334Sgshapiro If an error mail is created, and the mail is split across different 188594334Sgshapiro queue directories, and SuperSafe is off, then write the mail 188694334Sgshapiro to disk before splitting it, otherwise an assertion is 188794334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 188894334Sgshapiro of INTERMETA. 188994334Sgshapiro Fix possible race condition that could cause sendmail to forget 189094334Sgshapiro running queues.

Problem noted by Jon 192994334Sgshapiro Lusky of ISS Atlanta. 193094334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 193194334Sgshapiro directories are used and mail is sent to a mailing list 193294334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 193394334Sgshapiro of Concordia University. 193494334Sgshapiro Fix class map parsing code if optional key is specified. Problem 193594334Sgshapiro found by Mario Nigrovic. 193694334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 193794334Sgshapiro incoming messages. A leading dot is always stripped by the 193894334Sgshapiro SMTP receiver regardless of whether or not it is followed by 193994334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 194094334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 194194334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 194294334Sgshapiro Elvers. 194394334Sgshapiro Correct the statistics gathered for total number of connections. 194494334Sgshapiro Instead of being the exact same number as the total number 194594334Sgshapiro of messages (T line in mailstats) it now represents the 194694334Sgshapiro total number of TCP connections. 194794334Sgshapiro Be more explicit about syntax errors in addresses, especially 194894334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 194994334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 195094334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 195194334Sgshapiro are used.

Based on 195994334Sgshapiro patch by Bryan Costales. 196094334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 196194334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 196294334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 196394334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 196494334Sgshapiro errors. By doing so, the host was marked as having a 196594334Sgshapiro temporary problem and other mail destined for that host was 196694334Sgshapiro queued for the next queue run. Problem noted by Fletcher 196794334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 196894334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 196994334Sgshapiro and Neil Rickert of Northern Illinois University. 197094334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 197194334Sgshapiro which drop the connection instead of responding to the 197294334Sgshapiro command). 197394334Sgshapiro Portability: 197494334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 197598121Sgshapiro available. 197694334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 197794334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 197894334Sgshapiro settings. Patch from Elias Halldor Agustsson of 197994334Sgshapiro Skyrr. 198094334Sgshapiro Fix dependency building on Mac OS X and Darwin.

From 198494334Sgshapiro Rajesh Somasund of Hewlett-Packard. 198594334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 198694334Sgshapiro SMTP AUTH information. This feature was actually added in 198794334Sgshapiro 8.12.0 but a release note was not included. 198894334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 198994334Sgshapiro parameter is set and the LDAP lookup returns a temporary 199094334Sgshapiro error. 199194334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 199294334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 199394334Sgshapiro Krzysztof Oledzki. 199494334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 199594334Sgshapiro initialization as aliases are not needed for the MSP. 199694334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 199794334Sgshapiro is in use. Patch from Andrzej Filip. 199894334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 199994334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 200094334Sgshapiro This will only have an effect if a parameter is specified, 200194334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 200294334Sgshapiro it is embedded in square brackets. Problem noted by 200394334Sgshapiro Theo Van Dinter of Collective Technologies. 200494334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 200594334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 200694334Sgshapiro to allow for the proper time zone on systems where the 200794334Sgshapiro default results in misleading time stamps. That is, syslog 200894334Sgshapiro time stamps and Date headers on submitted mail will use the 200994334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 201094334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 201194334Sgshapiro by Neil Rickert of Northern Illinois University. 201294334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 201394334Sgshapiro binary.

Problem 212490792Sgshapiro noted by Neil Rickert of Northern Illinois University. 212590792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 212690792Sgshapiro dropping the connection during an SMTP transaction, stop 212790792Sgshapiro sending commands. This prevents bogus "Bad file number" 212890792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 212990792Sgshapiro Worcester Polytechnic Institute. 213090792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 213190792Sgshapiro almost always too small; do not guess the size at all. 213290792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 213390792Sgshapiro Compaq Computer Corp. 213490792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 213590792Sgshapiro properly. Problem noted by Valdis Kletnieks of Virginia 213690792Sgshapiro Tech. 213790792Sgshapiro Portability: 213890792Sgshapiro Fix IPv6 network interface probing on HP-UX 11.X. Based on 213990792Sgshapiro patch provided by HP. 214090792Sgshapiro Mac OS X (aka Darwin) has a broken setreuid() call, but a 214190792Sgshapiro working seteuid() call. From Daniel J.

This 214690792Sgshapiro fixes a problem that caused additional bogus 214790792Sgshapiro characters to be written to the qf file. Problem 214890792Sgshapiro noted by Tapani Tarvainen. 214990792Sgshapiro Set LDA_USE_LOCKF by default for UnixWare. Problem noted 215090792Sgshapiro by Boyd Lynn Gerber. 215190792Sgshapiro Add support for HP MPE/iX. See sendmail/README for port 215290792Sgshapiro information. From Mark Bixby of Hewlett-Packard. 215390792Sgshapiro New portability defines HASNICE, HASRRESVPORT, USE_ENVIRON, 215490792Sgshapiro USE_DOUBLE_FORK, and NEEDLINK. See sendmail/README 215590792Sgshapiro for more information. From Mark Bixby of 215690792Sgshapiro Hewlett-Packard. 215790792Sgshapiro If an OS doesn't have a method of finding free disk space 215890792Sgshapiro (SFS_NONE), lie and say there is plenty of space. 215990792Sgshapiro From Mark Bixby of Hewlett-Packard. 216090792Sgshapiro Add support for AIX 5.1.

Problem noted by Nikos Voutsinas of the 219490792Sgshapiro University of Athens. 219590792Sgshapiro New Files: 219690792Sgshapiro cf/cf/generic-mpeix.cf 219790792Sgshapiro cf/cf/generic-mpeix.mc 219890792Sgshapiro cf/ostype/freebsd5.m4 219990792Sgshapiro cf/ostype/mpeix.m4 220090792Sgshapiro devtools/OS/AIX.5.1 220190792Sgshapiro devtools/OS/MPE-iX 220290792Sgshapiro include/sm/os/sm_os_mpeix.h 220390792Sgshapiro libsm/mpeix.c 220490792Sgshapiro 220590792Sgshapiro8.12.1/8.12.1 2001/10/01 220690792Sgshapiro SECURITY: Check whether dropping group privileges actually succeeded 220790792Sgshapiro to avoid possible compromises of the mail system by 220890792Sgshapiro supplying bogus data. Add configuration options for 220990792Sgshapiro different set*gid() calls to reset saved gid. Problem 221090792Sgshapiro found by Michal Zalewski. 221190792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 221290792Sgshapiro privileges by disabling debugging (command line -d flag) 221390792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 221490792Sgshapiro used. Suggested by Michal Zalewski. 221590792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 221690792Sgshapiro Problem found by Michal Zalewski. 221790792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 221890792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 221990792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 222090792Sgshapiro If debugging is turned on (-d0.10) print not just the default 222190792Sgshapiro values for configuration file and pid file but also the 222290792Sgshapiro selected values. Problem noted by Brad Chapman. 222390792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 222490792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 222590792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 222690792Sgshapiro this only applied to hostname canonification. Problem 222790792Sgshapiro noted by Bill Fenner of AT&T Research. 222890792Sgshapiro Ignore comments in NIS host records when trying to find the 222990792Sgshapiro canonical name for a host. 223090792Sgshapiro When sendmail has extra privileges, limit mail submission command 223190792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 223290792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 223390792Sgshapiro suggestion from Michal Zalewski. 223490792Sgshapiro Portability: 223590792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 223690792Sgshapiro `uname` does not given complete information. 223790792Sgshapiro Problem noted by Keith Neufeld of the Cessna 223890792Sgshapiro Aircraft Company. 223990792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 224090792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 224190792Sgshapiro Avoid compiler warnings by not using pointers to pass 224290792Sgshapiro integers.

You need to create a new user and 227590792Sgshapiro a new group before installing sendmail (both called smmsp by 227690792Sgshapiro default). The installation process tries to install 227790792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 227890792Sgshapiro default. Please see sendmail/SECURITY for details. 227990792Sgshapiro SECURITY: Check for group and world writable forward and :include: 228090792Sgshapiro files.

Suggested 228990792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 229090792Sgshapiro (IdS). 229190792Sgshapiro Fixed problem of a global variable being used for a timeout jump 229290792Sgshapiro point where the variable could become overused for more than 229390792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 229490792Sgshapiro a corrupted stack causing a core dump. The timeout is now 229590792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 229690792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 229790792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 229890792Sgshapiro checks (group ID of RunAsUser). This allows use of a 229990792Sgshapiro set-group-ID sendmail binary for initial message submission 230090792Sgshapiro and no set-user-ID root sendmail is needed. For details 230190792Sgshapiro see sendmail/SECURITY. 230290792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 230390792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 230490792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 230590792Sgshapiro with a fallback of sendmail.cf as configuration file. See 230690792Sgshapiro sendmail/SECURITY. 230790792Sgshapiro New configuration file option UseMSP to allow group writable queue 230890792Sgshapiro files if the group is the same as that of a set-group-ID 230990792Sgshapiro sendmail binary. See sendmail/SECURITY. 231090792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 231190792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 231290792Sgshapiro is sendmail.cf (to be backward compatible). This selection 231390792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 231490792Sgshapiro file: client or mta). See sendmail/SECURITY. 231590792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 231690792Sgshapiro command has been removed. 231790792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 231890792Sgshapiro at compile time or per host (ruleset). 231990792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 232090792Sgshapiro used to look up local mail recipients; the default value 232190792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 232290792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 232390792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 232490792Sgshapiro long, to accomodate envelope splitting. File systems with 232590792Sgshapiro a 14 character file name length limit are no longer 232690792Sgshapiro supported. 232790792Sgshapiro Recipient list used for delivery now gets internally ordered by 232890792Sgshapiro hostsignature (character string version of MX RR). This orders 232990792Sgshapiro recipients for the same MX RR's together meaning smaller 233090792Sgshapiro portions of the list need to be scanned (instead of the whole 233190792Sgshapiro list) each delivery() pass to determine piggybacking. The 233290792Sgshapiro significance of the change is better the larger the recipient 233390792Sgshapiro list. Hostsignature is now created during recipient list 233490792Sgshapiro creation rather than just before delivery. 233590792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 233690792Sgshapiro piggybacking (called coincidental) extended to coattail 233790792Sgshapiro piggybacking. Rather than complete MX RR matching 233890792Sgshapiro (coincidental) piggybacking is done if just the lowest value 233990792Sgshapiro preference matches (coattail). 234090792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 234190792Sgshapiro try other MX hosts if available. 234290792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 234390792Sgshapiro outgoing (client-side) SMTP Authentication. 234490792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 234590792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 234690792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 234790792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 234890792Sgshapiro A new ruleset authinfo can be used to return client side 234990792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 235090792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 235190792Sgshapiro removed in future versions. 235290792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 235390792Sgshapiro requires 334. Mercury 1.48 is a known offender. 235490792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 235590792Sgshapiro for the security layer in SMTP AUTH (SASL). See 235690792Sgshapiro doc/op/op.me for details. 235790792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 235890792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 235990792Sgshapiro signed the presented certificate, the CN and the MD5 hash 236090792Sgshapiro of the presented certificate, respectively. 236190792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 236290792Sgshapiro New ruleset srv_features to enable/disable certain features in the 236390792Sgshapiro server per connection. See doc/op/op.me for details. 236490792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 236590792Sgshapiro recipient; useful to decide whether a conection is secure 236690792Sgshapiro enough on a per recipient basis. 236790792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 236890792Sgshapiro for STARTTLS. 236990792Sgshapiro If no certificate has been requested, the macro {verify} has the 237090792Sgshapiro value "NOT". 237190792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 237290792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 237390792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 237490792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 237590792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 237690792Sgshapiro really required. This change results in a noticable 237790792Sgshapiro performance gains on most machines. Moreover, if shared 237890792Sgshapiro memory is in use, reuse the key several times. 237990792Sgshapiro Add queue groups which can be used to group queue directories with 238090792Sgshapiro the same behavior together. See doc/op/op.me for details. 238190792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 238290792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 238390792Sgshapiro are initially sorted which may result in faster envelope 238490792Sgshapiro splitting. If the mail is submitted directly from the 238590792Sgshapiro command line, then the value also limits the number of 238690792Sgshapiro processes to deliver the envelopes; if more envelopes are 238790792Sgshapiro created they are only queued up and must be taken care of 238890792Sgshapiro by a queue run. 238990792Sgshapiro The check for 'enough disk space' now pays attention to which file 239090792Sgshapiro system each queue directory resides in. 239190792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 239290792Sgshapiro New option QueueFileMode for the default permissions of queue files. 239390792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 239490792Sgshapiro group (one or more queues in a multi-queue environment 239590792Sgshapiro collected together) to process the same work list at the 239690792Sgshapiro same time. 239790792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 239890792Sgshapiro active queue runner processes. 239990792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 240090792Sgshapiro runners per queue group. 240190792Sgshapiro Queue member selection by substring pattern matching now allows 240290792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 240390792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 240490792Sgshapiro of the queue that match during processing. 240590792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 240690792Sgshapiro periodically forking a child to process the queue, a single 240790792Sgshapiro child is forked for each queue that sleeps between queue 240890792Sgshapiro runs. A SIGHUP signal can be sent to restart this 240990792Sgshapiro persistent queue runner. 241090792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 241190792Sgshapiro sendmail process which only runs the queue at an interval: 241290792Sgshapiro sendmail -q15m). 241390792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 241490792Sgshapiro Proposed by Thom O'Connor. 241590792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 241690792Sgshapiro unless the new -qf option or -v is used. 241790792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 241890792Sgshapiro several queue runners are started by hand to avoid contention. 241990792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 242090792Sgshapiro of the qf file (older entries first). 242190792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 242290792Sgshapiro a client to specify an amount of time within which an e-mail 242390792Sgshapiro should be delivered. New option DeliverByMin added to set the 242490792Sgshapiro minimum amount of time or disable the extension. 242590792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 242690792Sgshapiro not allowed unless escaped or quoted. 242790792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 242890792Sgshapiro by Leif Johansson of Stockholm University, which was based on 242990792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 243090792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 243190792Sgshapiro Technology, Stockholm, Sweden. 243290792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 243390792Sgshapiro behavior (no MX lookups), put the name in square brackets. 243490792Sgshapiro Proposed by Thom O'Connor. 243590792Sgshapiro Use shared memory to store free space of filesystems that are used 243690792Sgshapiro for queues, if shared memory is available and if a key is set 243790792Sgshapiro via SharedMemoryKey. This minimizes the number of system 243890792Sgshapiro calls to check the available space. See doc/op/op.me for 243990792Sgshapiro details. 244090792Sgshapiro If shared memory is compiled in the option -bP can be used to print 244190792Sgshapiro the number of entries in the queue(s). 244290792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 244390792Sgshapiro and the usual documentation for details. 244490792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 244590792Sgshapiro Remove '-U' (initial user submission) command line option as 244690792Sgshapiro announced in 8.10. 244790792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 244890792Sgshapiro New macro {addr_type} which contains whether the current address is 244990792Sgshapiro an envelope sender or recipient address. Suggested by 245090792Sgshapiro Neil Rickert of Northern Illinois University. 245190792Sgshapiro Two new options for host maps: -d (retransmission timeout), 245290792Sgshapiro -r (number of retries). 245390792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 245490792Sgshapiro separator such that a lookup can return both an attribute 245590792Sgshapiro and value separated by the given separator. 245690792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 245790792Sgshapiro to map class arith. 245890792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 245990792Sgshapiro (errors that occur when sending an error message) are dropped. 246090792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 246190792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 246290792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 246390792Sgshapiro requirements for files containing secret keys. This is 246490792Sgshapiro necessary for the MSP if client authentification is used. 246590792Sgshapiro Properly handle quoted filenames for class files (to allow for 246690792Sgshapiro filenames with spaces). 246790792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 246890792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 246990792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 247090792Sgshapiro {if_addr_out} address of interface of outgoing connection. 247190792Sgshapiro {if_family_out} family of interface of outgoing connection. 247290792Sgshapiro The latter two are only set if the interface does not belong 247390792Sgshapiro to the loopback net. 247490792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 247590792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 247690792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 247790792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 247890792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 247990792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 248090792Sgshapiro all connections for a single delivery attempt to succeed. 248190792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 248290792Sgshapiro a threshold number of recipients has been rejected (option 248390792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 248490792Sgshapiro Development Group. 248590792Sgshapiro New option DelayLA to delay connections if the load averages 248690792Sgshapiro exceeds the specified value. The default of 0 does not 248790792Sgshapiro change the previous behavior. A value greater than 0 248890792Sgshapiro will cause sendmail to sleep for one second on most 248990792Sgshapiro SMTP commands and before accepting connections if that 249090792Sgshapiro load average is exceeded. 249190792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 249290792Sgshapiro recipients that are sent during a connection to a mailer. 249390792Sgshapiro This also introduces a new mailer field 'r' which defines 249490792Sgshapiro the maximum number of recipients (defaults to 100). 249590792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 249690792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 249790792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 249890792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 249990792Sgshapiro instead. 250090792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 250190792Sgshapiro builtin mailer pathnames. Use TCP instead. 250290792Sgshapiro PH map code updated to use the new libphclient API instead of the 250390792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 250490792Sgshapiro University of Illinois at Urbana-Champaign. 250590792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 250690792Sgshapiro for direct (command line) submissions. 250790792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 250890792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 250990792Sgshapiro Hagino of the KAME Project. 251090792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 251190792Sgshapiro whose content is rewritten similar to Reply-To:. 251290792Sgshapiro Proposed by Andrzej Filip. 251390792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 251490792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 251590792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 251690792Sgshapiro AUTH/STARTTLS related logfile entries. 251790792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 251890792Sgshapiro before logging. 251990792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 252090792Sgshapiro (at LogLevel 9/10 or higher). 252190792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 252290792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 252390792Sgshapiro in which most commands are rejected due to check_relay or 252490792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 252590792Sgshapiro Change logging format for cloned envelopes to be similar to that for 252690792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 252790792Sgshapiro of the Universitat Regensburg. 252890792Sgshapiro Added libsm, a C library of general purpose abstractions including 252990792Sgshapiro assertions, tracing and debugging with named debug categories, 253090792Sgshapiro exception handling, malloc debugging, resource pools, 253190792Sgshapiro portability abstractions, and an extensible buffered I/O 253290792Sgshapiro package. It will at some point replace libsmutil. 253390792Sgshapiro See libsm/index.html for details. 253490792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 253590792Sgshapiro care of by fork() and exit(). 253690792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 253790792Sgshapiro more consistent portablity amongst different platforms 253890792Sgshapiro new and old (from new libsm). 253990792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 254090792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 254190792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 254290792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 254390792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 254490792Sgshapiro synchronizations calls. 254590792Sgshapiro Add per-recipient status information to mailq -v output. 254690792Sgshapiro T_ANY queries are no longer used by sendmail. 254790792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 254890792Sgshapiro too (see include/sm/cdefs.h for more info). 254990792Sgshapiro sendmail -d now has general support for named debug categories. 255090792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 255190792Sgshapiro for details. 255290792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 255390792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 255490792Sgshapiro generated by this condition were illegal (not RFC conform). 255590792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 255690792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 255790792Sgshapiro mailer and the recipient has hence been rejected during the 255890792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 255990792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 256090792Sgshapiro that do not have postmaster defined. If an email was sent 256190792Sgshapiro from an address to which a DSN cannot be returned and 256290792Sgshapiro in which at least one recipient address is non-deliverable, 256390792Sgshapiro then that email had been delivered in each queue run. 256490792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 256590792Sgshapiro degli Studi dell'Insubria. 256690792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 256790792Sgshapiro i.e., the corresponding code is always compiled in now. 256890792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 256990792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 257090792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 257190792Sgshapiro attempting to canonify a hostname, some broken nameservers 257290792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 257390792Sgshapiro lookups. If you want to excuse this behavior, use this new 257490792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 257590792Sgshapiro Mark Roth of the University of Illinois at 257690792Sgshapiro Urbana-Champaign. 257790792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 257890792Sgshapiro noted by Joy Latten of IBM. 257990792Sgshapiro ConnectionRateThrottle limits the number of connections per second 258090792Sgshapiro to each daemon individually, not the overall number of 258190792Sgshapiro connections. 258290792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 258390792Sgshapiro sendmail to use a default alias schema as outlined in the 258490792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 258590792Sgshapiro cf/README. 258690792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 258790792Sgshapiro the first character after the class name is not a '/' or a 258890792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 258990792Sgshapiro rest of the line will be parsed as a map lookup. This 259090792Sgshapiro allows classes to be filled via a map lookup. See op.me 259190792Sgshapiro for more syntax information. Specifically, this can be 259290792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 259390792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 259490792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 259590792Sgshapiro example). 259690792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 259790792Sgshapiro the default schema used in the above two items. 259890792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 259990792Sgshapiro warning if a program being run from a mailer or file class 260090792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 260190792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 260290792Sgshapiro if a program being run from a mailer or file class 260390792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 260490792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 260590792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 260690792Sgshapiro (without quotes) will disable this and return to the 260790792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 260890792Sgshapiro Suggested by Bryan Stansell of GNAC. 260990792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 261090792Sgshapiro HELO/EHLO commands. 261190792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 261290792Sgshapiro possible protocol family which may be used for outgoing 261390792Sgshapiro connections. Restrictions placed on one family only affect 261490792Sgshapiro outgoing connections on that particular family. Because of 261590792Sgshapiro this change, the ${client_flags} macro is not set until the 261690792Sgshapiro connection is established. Based on patch from Motonori 261790792Sgshapiro Nakamura of Kyoto University. 261890792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 261990792Sgshapiro when the -bv option is given by users who are neither root 262090792Sgshapiro nor the TrustedUser so users can not read private aliases, 262190792Sgshapiro forwards, or :include: files. It also will override the -v 262290792Sgshapiro (verbose) command line option. 262390792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 262490792Sgshapiro address can't be used for the outgoing connection, fall 262590792Sgshapiro back to the settings in ClientPortOptions (if set). 262690792Sgshapiro Problem noted by John Beck of Sun Microsystems. 262790792Sgshapiro New named config file rule check_data for DATA command (input: 262890792Sgshapiro number of recipients). Based on patch from Mark Roth of 262990792Sgshapiro the University of Illinois at Urbana-Champaign. 263090792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 263190792Sgshapiro can be specified using the '#' option character. For 263290792Sgshapiro example, 'ETRN #queuegroup'. 263390792Sgshapiro If an LDAP server times out or becomes unavailable, close the 263490792Sgshapiro current connection and reopen to get to one of the fallback 263590792Sgshapiro servers. Patch from Paul Hilchey of the University of 263690792Sgshapiro British Columbia. 263790792Sgshapiro Make default error number on $#error messages 550 instead of 501 263890792Sgshapiro because 501 is not allowed on all commands. 263990792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 264090792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 264190792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 264290792Sgshapiro if required. 264390792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 264490792Sgshapiro class instead. 264590792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 264690792Sgshapiro "IPv6:" tag to identify the address properly. For example, 264790792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 264890792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 264990792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 265090792Sgshapiro MTA is running. For example, during a queue run. 265190792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 265290792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 265390792Sgshapiro Nelson of IBM. 265490792Sgshapiro The maximum number of commands before the MTA slows down when too 265590792Sgshapiro many "light weight" commands have been received are now 265690792Sgshapiro configurable during compile time. The current values and 265790792Sgshapiro their defaults are: 265890792Sgshapiro MAXBADCOMMANDS 25 unknown commands 265990792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 266090792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 266190792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 266290792Sgshapiro MAXETRNCOMMANDS 8 ETRN 266390792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 266490792Sgshapiro Costales of SL3D, Inc. 266590792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 266690792Sgshapiro ${MyMacro} is defined but also that it is not empty. 266790792Sgshapiro Properly quote usernames with special characters if they are used 266890792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 266990792Sgshapiro Meteorological Institute. 267090792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 267190792Sgshapiro messages for messages for mailing list expanded addresses 267290792Sgshapiro which are not delivered on the initial attempt. 267390792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 267490792Sgshapiro the final dot has been sent to avoid affecting future 267590792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 267690792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 267790792Sgshapiro file systems that require to call fsync() for a directory 267890792Sgshapiro if the meta-data in it has been changed. This should be 267990792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 268090792Sgshapiro See sendmail/README for further information. 268190792Sgshapiro Avoid file locking deadlock when updating the statistics file if 268290792Sgshapiro sendmail is signaled to terminate. Problem noted by 268390792Sgshapiro Christophe Wolfhugel of France Telecom. 268490792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 268590792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 268690792Sgshapiro the Finnish Meteorological Institute. 268790792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 268890792Sgshapiro from Peter A. Friend of EarthLink. 268990792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 269090792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 269190792Sgshapiro flora.ca. 269290792Sgshapiro Portability: 269390792Sgshapiro Remove support for AIX 2, which supports only 14 character 269490792Sgshapiro filenames and is outdated anyway. Suggested by 269590792Sgshapiro Valdis Kletnieks of Virginia Tech. 269690792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 269790792Sgshapiro i.e., use default /usr/sbin, change owner/group 269890792Sgshapiro of man pages and user-executable to root/sys, set 269990792Sgshapiro optimization limit to 0 (unlimited). Based on patch 270090792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 270190792Sgshapiro Hurtta of the Finnish Meteorological Institute. 270290792Sgshapiro Do not assume LDAP support is installed by default under 270390792Sgshapiro Solaris 8 and later. 270490792Sgshapiro Add support for OpenUNIX. 270590792Sgshapiro CONFIG: Increment version number of config file to 10. 270690792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 270790792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 270890792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 270990792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 271090792Sgshapiro temporary lookup failures. 271190792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 271290792Sgshapiro action to be taken by aborting the search for domain names 271390792Sgshapiro or IP nets. 271490792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 271590792Sgshapiro relay address as long as the other part allows the email 271690792Sgshapiro to get through. 271790792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 271890792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 271990792Sgshapiro entry like user+*@domain. This allows handling of details by 272090792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 272190792Sgshapiro introduced to match only non-empty details of addresses. 272290792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 272390792Sgshapiro and hence there is no required order within the MAILER 272490792Sgshapiro section anymore except for MAILER(`uucp') which must come 272590792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 272690792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 272790792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 272890792Sgshapiro as canonical.

If sendmail needs to drop 343664562Sgshapiro these privileges and the operating system doesn't set the 343764562Sgshapiro saved-uid as well, exit with an error. Problem noted by 343864562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 343964562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 344064562Sgshapiro it populates. It is possible that some broken 344164562Sgshapiro implementations of snprintf() exist that do not do this. 344264562Sgshapiro Systems in this category should compile with 344364562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 344464562Sgshapiro system and report broken implementations to 344564562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 344664562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 344764562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 344864562Sgshapiro Implementation influenced by the example programs of 344964562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 345064562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 345164562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 345264562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 345364562Sgshapiro cf/README and doc/op/op.*. 345464562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 345564562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 345664562Sgshapiro ${server_name}, and ${server_addr}. These are documented 345764562Sgshapiro in cf/README and doc/op/op.*. 345864562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 345964562Sgshapiro random data. 346064562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 346164562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 346264562Sgshapiro try to use STARTTLS despite the security problems. 346364562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 346464562Sgshapiro support encryption. Based on code contributed by Tim 346564562Sgshapiro Martin of CMU. 346664562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 346764562Sgshapiro strength factor. 346864562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 346964562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 347064562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 347164562Sgshapiro of CMU. 347264562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 347364562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 347464562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 347564562Sgshapiro Fix the default family selection for DaemonPortOptions. As 347664562Sgshapiro documented, unless a family is specified in a 347764562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 347864562Sgshapiro also the default if no DaemonPortOptions value is set. 347964562Sgshapiro Therefore, IPv6 users should configure additional sockets 348064562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 348164562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 348264562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 348364562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 348464562Sgshapiro the interface information for an outgoing connection. 348564562Sgshapiro Not doing so was creating a mismatch between the socket 348664562Sgshapiro family and address used in subsequent connections if the 348764562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 348864562Sgshapiro by John Beck of Sun Microsystems. 348964562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 349064562Sgshapiro family based on the IP address. ${if_family} is no longer 349164562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 349264562Sgshapiro of Sun Microsystems. 349364562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 349464562Sgshapiro macros for both the incoming interface address/family and 349564562Sgshapiro the outgoing interface address/family. In order for M=b 349664562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 349764562Sgshapiro the incoming information in the queue file for later 349864562Sgshapiro delivery attempts. 349964562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 350064562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 350164562Sgshapiro smoe.org. 350264562Sgshapiro Add more vigilance in checking for putc() errors on output streams 350364562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 350464562Sgshapiro noted by Graeme Hewson of Oracle. 350564562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 350664562Sgshapiro Problem noted by Ajay Matia. 350764562Sgshapiro Under certain circumstances, an address could be listed as deferred 350864562Sgshapiro but would be bounced back to the sender as failed to be 350964562Sgshapiro delivered when it really should have been queued.

Problem noted by Neil Rickert 351764562Sgshapiro of Northern Illinois University. 351864562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 351964562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 352064562Sgshapiro Convert the free disk space shown in a control socket status query 352164562Sgshapiro to kilobyte units. 352264562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 352364562Sgshapiro looking up the hostname, requeue the message for a later 352464562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 352564562Sgshapiro Polytechnic. 352664562Sgshapiro Under the proper circumstances, failed connections would be recorded 352764562Sgshapiro as "Bad file number" instead of "Connection failed" in the 352864562Sgshapiro queue file and persistent host status. Problem noted by 352964562Sgshapiro Graeme Hewson of Oracle. 353064562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 353164562Sgshapiro within the hoststatus directory (e.g., lost+found). 353264562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 353364562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 353464562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 353564562Sgshapiro If a message data file can't be opened at delivery time, panic and 353664562Sgshapiro abort the attempt instead of delivering a message that 353764562Sgshapiro states "<<< No Message Collected >>>". 353864562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 353964562Sgshapiro restrictive.

Problem noted 354764562Sgshapiro by Valdis Kletnieks of Virginia Tech. 354864562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 354964562Sgshapiro only the first to open the connection is allowed to close 355064562Sgshapiro it so a later map close doesn't break the connection for 355164562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 355264562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 355364562Sgshapiro authentication.

Problem noted by Michal Zalewski of the 380764562Sgshapiro "Internet for Schools" project (IdS). 380864562Sgshapiro SECURITY: There is a potential for a denial of service attack if 380964562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 381064562Sgshapiro sendmail process while it is rebuilding the aliases file 381164562Sgshapiro (leaving it in an inconsistent state). This option and 381264562Sgshapiro its use is deprecated and will be removed from a future 381364562Sgshapiro version of sendmail. 381464562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 381564562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 381664562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 381764562Sgshapiro (IdS). 381864562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 381964562Sgshapiro a large number of files. See cf/README for more details. 382064562Sgshapiro The directory structure of the distribution has changed slightly 382164562Sgshapiro for easier code sharing among the programs. 382264562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 382364562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 382464562Sgshapiro which hold the client's authentication credentials, 382564562Sgshapiro the mechanism used for authentication, and the 382664562Sgshapiro authorization identity (i.e., the AUTH= parameter if 382764562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 382864562Sgshapiro On systems which use the Torek stdio library (all of the BSD 382964562Sgshapiro distributions), use memory-buffered files to reduce 383064562Sgshapiro file system overhead by not creating temporary files on 383164562Sgshapiro disk. Contributed by Exactis.com, Inc. 383264562Sgshapiro New option DataFileBufferSize to control the maximum size of a 383364562Sgshapiro memory-buffered data (df) file before a disk-based file is 383464562Sgshapiro used. Contributed by Exactis.com, Inc. 383564562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 383664562Sgshapiro memory-buffered transcript (xf) file before a disk-based 383764562Sgshapiro file is used. Contributed by Exactis.com, Inc. 383864562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 383964562Sgshapiro now listen on several different ports. Use: 384064562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 384164562Sgshapiro to run a Message Submission Agent (MSA); this is turned 384264562Sgshapiro on by default in m4-generated .cf files; it can be turned 384364562Sgshapiro off with FEATURE(`no_default_msa'). 384464562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 384564562Sgshapiro begin using RFC 2476 Message Submission for initial user 384664562Sgshapiro message submission. XUSR may disappear from a future release. 384764562Sgshapiro The new '-G' (relay (gateway) submission) command line option 384864562Sgshapiro indicates that the message being submitted from the command 384964562Sgshapiro line is for relaying, not initial submission. This means 385064562Sgshapiro the message will be rejected if the addresses are not fully 385164562Sgshapiro qualified and no canonicalization will be done. Future 385264562Sgshapiro releases may even reject improperly formed messages. 385364562Sgshapiro The '-U' (initial user submission) command line option is 385464562Sgshapiro deprecated and may be removed from a future release. 385564562Sgshapiro Mail user agents should begin using '-G' to indicate that 385664562Sgshapiro this is a relay submission (the inverse of -U). 385764562Sgshapiro The next release of sendmail will assume that any message submitted 385864562Sgshapiro from the command line is an initial user submission and act 385964562Sgshapiro accordingly. 386064562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 386164562Sgshapiro program or deliver to file as the owner of that file, the 386264562Sgshapiro address is marked as unsafe. This means if RunAsUser is 386364562Sgshapiro set, users won't be able to use programs or delivery to 386464562Sgshapiro files in their .forward files. Administrators can override 386564562Sgshapiro this by setting the DontBlameSendmail option to the new 386664562Sgshapiro setting NonRootSafeAddr. 386764562Sgshapiro Allow group or world writable directories if the sticky bit is set 386864562Sgshapiro on the directory and DontBlameSendmail is set to 386964562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 387064562Sgshapiro InCert Software. 387164562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 387264562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 387364562Sgshapiro set in the DontBlameSendmail option. Requested by many. 387464562Sgshapiro New Timeout.control option to limit the total time spent satisfying 387564562Sgshapiro a control socket request. 387664562Sgshapiro New Timeout.resolver options for controlling BIND resolver 387764562Sgshapiro settings: 387864562Sgshapiro Timeout.resolver.retrans 387964562Sgshapiro Sets the resolver's retransmission time interval (in 388064562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 388164562Sgshapiro and Timeout.resolver.retrans.normal. 388264562Sgshapiro Timeout.resolver.retrans.first 388364562Sgshapiro Sets the resolver's retransmission time interval (in 388464562Sgshapiro seconds) for the first attempt to deliver a message. 388564562Sgshapiro Timeout.resolver.retrans.normal 388664562Sgshapiro Sets the resolver's retransmission time interval (in 388764562Sgshapiro seconds) for all resolver lookups except the first 388864562Sgshapiro delivery attempt. 388964562Sgshapiro Timeout.resolver.retry 389064562Sgshapiro Sets the number of times to retransmit a resolver 389164562Sgshapiro query. Sets both Timeout.resolver.retry.first 389264562Sgshapiro and Timeout.resolver.retry.normal. 389364562Sgshapiro Timeout.resolver.retry.first 389464562Sgshapiro Sets the number of times to retransmit a resolver 389564562Sgshapiro query for the first attempt to deliver a message. 389664562Sgshapiro Timeout.resolver.retry.normal 389764562Sgshapiro Sets the number of times to retransmit a resolver 389864562Sgshapiro query for all resolver lookups except the first 389964562Sgshapiro delivery attempt. 390064562Sgshapiro Contributed by Exactis.com, Inc. 390164562Sgshapiro Support multiple queue directories. To use multiple queues, supply 390264562Sgshapiro a QueueDirectory option value ending with an asterisk. For 390364562Sgshapiro example, /var/spool/mqueue/q* will use all of the 390464562Sgshapiro directories or symbolic links to directories beginning with 390564562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 390664562Sgshapiro mind, the queue directory structure should not be changed 390764562Sgshapiro while sendmail is running. Queue runs create a separate 390864562Sgshapiro process for running each queue unless the verbose flag is 390964562Sgshapiro given on a non-daemon queue run. New items are randomly 391064562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 391164562Sgshapiro Support different directories for qf, df, and xf queue files; if 391264562Sgshapiro subdirectories or symbolic links to directories of those names 391364562Sgshapiro exist in the queue directories, they are used for the 391464562Sgshapiro corresponding queue files. Keep in mind, the queue 391564562Sgshapiro directory structure should not be changed while sendmail is 391664562Sgshapiro running. Proposed by Mathias Koerber of Singapore 391764562Sgshapiro Telecommunications Ltd. 391864562Sgshapiro New queue file naming system which uses a filename guaranteed to be 391964562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 392064562Sgshapiro without fancy file system locking. Queued items can be 392164562Sgshapiro moved between queues easily. Contributed by Exactis.com, 392264562Sgshapiro Inc. 392364562Sgshapiro Messages which are undeliverable due to temporary address failures 392464562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 392564562Sgshapiro set. Contributed by Exactis.com, Inc. 392664562Sgshapiro New command line option '-L tag' which sets the identifier used for 392764562Sgshapiro syslog. Contributed by Exactis.com, Inc. 392864562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 392964562Sgshapiro avoids opening and reading each queue file when preparing 393064562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 393164562Sgshapiro Shared memory counters and microtimers functionality has been 393264562Sgshapiro donated by Exactis.com, Inc. 393364562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 393464562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 393564562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 393664562Sgshapiro being added.

Use [IPC] 395364562Sgshapiro instead. 395464562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 395564562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 395664562Sgshapiro connections), IPC (which will be deprecated in a future 395764562Sgshapiro version), and FILE (for UNIX domain socket delivery). 395864562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 395964562Sgshapiro flags. 396064562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 396164562Sgshapiro body of the original message on delivery status 396264562Sgshapiro notifications. 396364562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 396464562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 396564562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 396664562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 396764562Sgshapiro Steve Schweinhart of America Online. 396864562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 396964562Sgshapiro not be set after rulesets are defined. Suggested by 397064562Sgshapiro Mitchell Blank Jr of Exec-PC. 397164562Sgshapiro Do not report temporary failure on delivery to files. In 397264562Sgshapiro interactive delivery mode, this would result in two SMTP 397364562Sgshapiro responses after the DATA command. Problem noted by 397464562Sgshapiro Nik Conwell of Boston University. 397564562Sgshapiro Check file close when mailing to files. Problem noted by Nik 397664562Sgshapiro Conwell of Boston University. 397764562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 397864562Sgshapiro Curtis W. Hillegas of Princeton University. 397964562Sgshapiro Always bind to the LDAP server regardless of whether you are using 398064562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 398164562Sgshapiro @Home Network. 398264562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 398364562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 398464562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 398564562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 398664562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 398764562Sgshapiro similar to check_rcpt etc. 398864562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 398964562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 399064562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 399164562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 399264562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 399364562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 399464562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 399564562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 399664562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 399764562Sgshapiro the corresponding DSN parameter values. Proposed by 399864562Sgshapiro Mathias Herberts. 399964562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 400064562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 400164562Sgshapiro before the message has been collected, thereafter it holds 400264562Sgshapiro the message size as computed by sendmail (and can be used 400364562Sgshapiro in check_compat). 400464562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 400564562Sgshapiro sendmail is using instead of the value of the DeliveryMode 400664562Sgshapiro option. 400764562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 400864562Sgshapiro Drop explicit From: if same as what would be generated only if it is 400964562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 401064562Sgshapiro Write pid to file also if sendmail only processes the queue. 401164562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 401264562Sgshapiro Log "low on disk space" only when necessary. 401364562Sgshapiro New macro ${load_avg} can be used to check the current load average. 401464562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 401564562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 401664562Sgshapiro is set. 401764562Sgshapiro Flag -S for maps to specify the character which is substituted 401864562Sgshapiro for spaces (instead of the default given by O BlankSub). 401964562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 402064562Sgshapiro This flag is set by default for the host map. Based on a 402164562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 402264562Sgshapiro Open maps only on demand, not at startup. 402364562Sgshapiro Log warning about unsupported IP address families. 402464562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 402564562Sgshapiro of the sum of all headers. This can be used to prevent 402664562Sgshapiro a denial-of-service attack. 402764562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 402864562Sgshapiro headers and parameters within those headers. This option 402964562Sgshapiro is intended to protect mail user agents from buffer 403064562Sgshapiro overflow attacks. 403164562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 403264562Sgshapiro alias recursion. 403364562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 403464562Sgshapiro Map type syslog to log the key via syslogd. 403564562Sgshapiro Entries in the alias file can be continued by putting a backslash 403664562Sgshapiro directly before the newline. 403764562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 403864562Sgshapiro dead.letter file, formerly hardcoded to 403964562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 404064562Sgshapiro default), sendmail will not attempt to save to a 404164562Sgshapiro system-wide dead.letter file if it can not bounce the mail 404264562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 404364562Sgshapiro file as it has in the past when the dead.letter file 404464562Sgshapiro could not be opened. 404564562Sgshapiro New option PidFile to define the location of the pid file. The 404664562Sgshapiro value of this option is macro expanded. 404764562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 404864562Sgshapiro process title shown in 'ps' listings. 404964562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 405064562Sgshapiro (along with the already existing macros): 405164562Sgshapiro ${daemon_info} Daemon information, e.g. 405264562Sgshapiro SMTP+queueing@00:30:00 405364562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 405464562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 405564562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 405664562Sgshapiro ${daemon_port} Daemon port, e.g., 25 405764562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 405864562Sgshapiro New macros especially for virtual hosting: 405964562Sgshapiro ${if_name} hostname of interface of incoming connection. 406064562Sgshapiro ${if_addr} address of interface of incoming connection. 406164562Sgshapiro The latter is only set if the interface does not belong to the 406264562Sgshapiro loopback net. 406364562Sgshapiro If a message being accepted via a method other than SMTP and 406464562Sgshapiro would be rejected by a header check, do not send the message. 406564562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 406664562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 406764562Sgshapiro Provide header value as quoted string in the macro 406864562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 406964562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 407064562Sgshapiro The length of the header value is stored in ${hdrlen}. 407164562Sgshapiro H*: allows to specify a default ruleset for header checks. This 407264562Sgshapiro ruleset will only be called if the individual header does 407364562Sgshapiro not have its own ruleset assigned. Suggested by Jan 407464562Sgshapiro Krueger of Unix-AG of University of Hannover. 407564562Sgshapiro The name of the header field stored in ${hdr_name}. 407664562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 407764562Sgshapiro removed if the config file version is greater than or equal 407864562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 407964562Sgshapiro input "token (1)" but does not match "token". 408064562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 408164562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 408264562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 408364562Sgshapiro Ericsson. 408464562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 408564562Sgshapiro messages with 8-bit text in headers. Problem noted by 408664562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 408764562Sgshapiro of Ericsson. 408864562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 408964562Sgshapiro modified database map file. Problem noted by Chris Adams 409064562Sgshapiro of Renaissance Internet Services. 409164562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 409264562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 409364562Sgshapiro queue up the message instead of bouncing it. 409464562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 409564562Sgshapiro standard does not provide any indication of what to do when 409664562Sgshapiro something other than 250 is received. Based on a patch 409764562Sgshapiro from Steve Schweinhart of America Online. 409864562Sgshapiro New option TrustedUser allows to specify a user who can own 409964562Sgshapiro important files instead of root. This requires HASFCHOWN. 410064562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 410164562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 410264562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 410364562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 410464562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 410564562Sgshapiro $? tests also whether the macro is non-null. 410664562Sgshapiro Print an error message if a mailer definition contains an invalid 410764562Sgshapiro equate name. 410864562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 410964562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 411064562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 411164562Sgshapiro mailer to return after sending all data to it. 411264562Sgshapiro Only free memory from the process list when adding a new process 411364562Sgshapiro into a previously filled slot. Previously, the memory was 411464562Sgshapiro freed at removal time. Since removal can happen in a 411564562Sgshapiro signal handler, this may leave the memory map in an 411664562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 411764562Sgshapiro David Cooley of Colby College. 411864562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 411964562Sgshapiro local users in the passwd file. The UserDB code has 412064562Sgshapiro already decided the message will be passed to another host 412164562Sgshapiro for processing. Fix from Tony Landells of Burdett 412264562Sgshapiro Buckeridge Young Limited. 412364562Sgshapiro Support LDAP authorization via either a file containing the 412464562Sgshapiro password or Kerberos V4 using the new map options 412564562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 412664562Sgshapiro distinguished_name is who to login as. The method can be 412764562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 412864562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 412964562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 413064562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 413164562Sgshapiro of Stanford University. 413264562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 413364562Sgshapiro deprecated and will be removed in a future version. 413464562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 413564562Sgshapiro and the map has the column delimiter set, it turns that 413664562Sgshapiro response into a delimiter separated string. The LDAP map 413764562Sgshapiro will traverse multiple entries as well. LDAP alias maps 413864562Sgshapiro automatically set the column delimiter to the comma. 413964562Sgshapiro Based on patch from Booker Bense of Stanford University and 414064562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 414164562Sgshapiro Support return of multiple values for a single LDAP lookup. The 414264562Sgshapiro values to be returned should be in a comma separated string. 414364562Sgshapiro For example, `-v "email,emailother"'. Patch from 414464562Sgshapiro Curtis W. Hillegas of Princeton University. 414564562Sgshapiro Allow the use of LDAP for alias maps. 414664562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 414764562Sgshapiro attributes found in the match will be returned. 414864562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 414964562Sgshapiro breaking up a single entry into multiple entries. This is 415064562Sgshapiro needed for LDAP alias file specifications to allow for 415164562Sgshapiro comma separated key and value strings. 415264562Sgshapiro Keep connections to LDAP server open instead of opening and closing 415364562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 415464562Sgshapiro connections such that multiple maps which use the same 415564562Sgshapiro host, port, bind DN, and authentication will only result in 415664562Sgshapiro a single connection to that host. 415764562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 415864562Sgshapiro Be more careful about checking for errors and freeing memory on 415964562Sgshapiro LDAP lookups. 416064562Sgshapiro Use asynchronous LDAP searches to save memory and network 416164562Sgshapiro resources. 416264562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 416364562Sgshapiro Increase portability to the Netscape LDAP libraries. 416464562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 416564562Sgshapiro replaced with the literal contents of the map lookup key -- 416664562Sgshapiro note that this means a lookup can be done using the LDAP 416764562Sgshapiro special characters. The new '%0' token can be used instead 416864562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 416964562Sgshapiro For example, if the LDAP map specification contains '-k 417064562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 417164562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 417264562Sgshapiro user attribute. Instead, if the LDAP map specification 417364562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 417464562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 417564562Sgshapiro with the name "*". 417664562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 417764562Sgshapiro more than one is returned, it is equivalent to no records 417864562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 417964562Sgshapiro alias dereference option; "-Z size" limits the number of 418064562Sgshapiro matches to return. 418164562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 418264562Sgshapiro LDAP maps. The value should only contain LDAP specific 418364562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 418464562Sgshapiro settings will be used for all LDAP maps unless they are 418564562Sgshapiro specified in the individual map specification ('K' 418664562Sgshapiro command). This option should be set before any LDAP maps 418764562Sgshapiro are defined. 418864562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 418964562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 419064562Sgshapiro Tech. 419164562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 419264562Sgshapiro particular, class entries get much smaller, which can be 419364562Sgshapiro important if you have large classes. 419464562Sgshapiro On network-related temporary failures, record the hostname which 419564562Sgshapiro gave error in the queued status message. Requested by 419664562Sgshapiro Ulrich Windl of the Universitat Regensburg. 419764562Sgshapiro Add new F=% mailer flag to allow for a store and forward 419864562Sgshapiro configuration. Mailers which have this flag will not attempt 419971345Sgshapiro delivery on initial receipt of a message or on queue runs 420064562Sgshapiro unless the queued message is selected using one of the 420164562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 420264562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 420364562Sgshapiro New option ControlSocketName which, when set, creates a daemon 420464562Sgshapiro control socket. This socket allows an external program to 420564562Sgshapiro control and query status from the running sendmail daemon 420664562Sgshapiro via a named socket, similar to the ctlinnd interface to the 420764562Sgshapiro INN news server. Access to this interface is controlled by 420864562Sgshapiro the UNIX file permissions on the named socket on most UNIX 420964562Sgshapiro systems (see sendmail/README for more information). An 421064562Sgshapiro example control program is provided as contrib/smcontrol.pl. 421164562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 421264562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 421364562Sgshapiro number of processors online on the system (if that can be 421464562Sgshapiro determined). For single processor machines, this change 421564562Sgshapiro has no effect. 421664562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 421764562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 421864562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 421964562Sgshapiro Motonori Nakamura of Kyoto University. 422064562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 422164562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 422264562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 422364562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 422464562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 422564562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 422664562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 422764562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 422864562Sgshapiro connection-based denial of service attacks. 422964562Sgshapiro Log basic information about authenticated connections at LogLevel 423064562Sgshapiro 10 or higher. 423164562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 423264562Sgshapiro information (from= syslog line). 423364562Sgshapiro Log the DSN code for each recipient if one is available as a new 423464562Sgshapiro equate (dsn=). 423564562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 4236120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 4237120256Sgshapiro sendmail/README for details.

Problem noted by Kari Hurtta of the 424164562Sgshapiro Finnish Meteorological Institute. 424264562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 424364562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 424464562Sgshapiro When a forward file points to an alias which runs a program, run 424564562Sgshapiro the program as the default user and the default group, not 424664562Sgshapiro the forward file user. This change also assures the 424764562Sgshapiro :include: directives in aliases are also processed using 424864562Sgshapiro the default user and group. Problem noted by Sergiu 424964562Sgshapiro Popovici of DNT Romania. 425064562Sgshapiro Prevent attempts to save a dead.letter file for a user with 425164562Sgshapiro no home directory (/no/such/directory).

If some of the recipients were rejected, it is 425864562Sgshapiro helpful to know the sender of the message. 425964562Sgshapiro Check the root directory (/) when checking a path for safety. 426064562Sgshapiro Problem noted by John Beck of Sun Microsystems. 426164562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 426264562Sgshapiro interactive and delivering to an alias which resolves to 426364562Sgshapiro multiple files. 426464562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 426564562Sgshapiro greater (see below); the help function doesn't print the 426664562Sgshapiro version of sendmail any longer, instead it is placed in 426764562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 426864562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 426964562Sgshapiro skipped and a version line (#vers) is introduced. The 427064562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 427164562Sgshapiro version is found, a warning is logged. The '#vers' 427264562Sgshapiro directive should be placed at the top of the help file. 427364562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 427464562Sgshapiro disk succeeded. Suggested by Nick Christenson. 427564562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 427664562Sgshapiro length before the attempt. 427764562Sgshapiro If a forward points to a filename for delivery, change to the 427864562Sgshapiro user's uid before checking permissions on the file. This 427964562Sgshapiro allows delivery to files on NFS mounted directories where 428064562Sgshapiro root is remapped to nobody. Problem noted by Harald 428164562Sgshapiro Daeubler of Universitaet Ulm. 428264562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 428364562Sgshapiro host status files, not all files. 428464562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 428564562Sgshapiro in the queue file for the message and set when delivery 428664562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 428764562Sgshapiro Wonderworks Inc. 428864562Sgshapiro Add support for storing information between rulesets using the new 428964562Sgshapiro macro map class. This can be used to store information 429064562Sgshapiro between queue runs as well using $={persistentMacros}. 429164562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 429264562Sgshapiro of Hannover. 429364562Sgshapiro New map class arith to allow for computations in rules. The 429464562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 429564562Sgshapiro as key. The two operands are specified as arguments; the 429664562Sgshapiro lookup returns the result of the computation. For example, 429764562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 429864562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 429964562Sgshapiro Add new syntax for header declarations which decide whether to 430064562Sgshapiro include the header based on a macro rather than a mailer 430164562Sgshapiro flag: 430264562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 430364562Sgshapiro This should be used along with $={persistentMacros}. 430464562Sgshapiro It can be used for adding headers to a message based on 430564562Sgshapiro the results of check_* and header check rulesets. 430664562Sgshapiro Allow new named config file rule check_eoh which is called after 430764562Sgshapiro all of the headers have been collected. The input to the 430864562Sgshapiro ruleset the number of headers and the size of all of the 430964562Sgshapiro headers in bytes separated by $|. This ruleset along with 431064562Sgshapiro the macro storage map can be used to correlate information 431164562Sgshapiro gathered between headers and to check for missing headers. 431264562Sgshapiro See cf/README or doc/op/op.ps for an example. 431364562Sgshapiro Change the default for the MeToo option to True to correspond 431464562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 431564562Sgshapiro option is deprecated and will be removed from a future 431664562Sgshapiro version. 431764562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 431864562Sgshapiro Change the sendmail binary default for SuperSafe to True. 431964562Sgshapiro Display ruleset names in debug and address test mode output 432064562Sgshapiro if referencing a named ruleset. 432164562Sgshapiro New mailer equate m= which will limit the number of messages 432264562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 432364562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 432464562Sgshapiro using it to sort. Now all the same domains are really run 432564562Sgshapiro through the queue together. If they have the same MX host, 432664562Sgshapiro then they will have a much better opportunity to use the 432764562Sgshapiro connection cache if available. This should be a reasonable 432864562Sgshapiro performance improvement. Patch from Randall Winchester of 432964562Sgshapiro the University of Maryland. 433064562Sgshapiro If a message is rejected by a header check ruleset, log who would 433164562Sgshapiro have received the message if it had not been rejected. 433264562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 433364562Sgshapiro queue immediately. No delivery attempt is made. 433464562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 433564562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 433664562Sgshapiro COMMANDS). 433764562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 433864562Sgshapiro but for outgoing connections. 433964562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 434064562Sgshapiro error messages and logging) and Modifiers, i.e. 434164562Sgshapiro a require authentication 434264562Sgshapiro b bind to interface through which mail has 434364562Sgshapiro been received 434464562Sgshapiro c perform hostname canonification 434564562Sgshapiro f require fully qualified hostname 434664562Sgshapiro h use name of interface for outgoing HELO 434764562Sgshapiro command 434864562Sgshapiro C don't perform hostname canonification 434964562Sgshapiro E disallow ETRN (see RFC 2476) 435064562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 435164562Sgshapiro h use name of interface for HELO command 435264562Sgshapiro The version number for queue files (qf) has been incremented to 4. 435364562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 435464562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 435564562Sgshapiro Institutes of Health. 435664562Sgshapiro If a mailer dies, print the status in decimal instead of octal 435764562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 435864562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 435964562Sgshapiro Move message priority from sender to recipient logging. Suggested by 436064562Sgshapiro Ulrich Windl of the Universitat Regensburg. 436164562Sgshapiro Add support for Berkeley DB 3.X. 436264562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 436364562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 436464562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 436564562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 436664562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 436764562Sgshapiro sub-options is set on the command line. Problem noted by 436864562Sgshapiro Graeme Hewson of Oracle. 436964562Sgshapiro Randomize equal preference MX records each time delivery is 437064562Sgshapiro attempted via a new connection to a host instead of once per 437164562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 437264562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 437364562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 437464562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 437564562Sgshapiro to hosts which have dynamically assigned names. 437664562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 437764562Sgshapiro the bounce for the same reason. If the body is not 8-bit 437864562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 437964562Sgshapiro not be included in the bounce. Problem noted by Valdis 438064562Sgshapiro Kletnieks of Virginia Tech. 438164562Sgshapiro The timeout for sending a message via SMTP has been changed from 438264562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 438364562Sgshapiro simply checks for progress on sending data every 5 minutes. 438464562Sgshapiro This will detect the inability to send information quicker 438564562Sgshapiro and reduce the number of processes simply waiting to 438664562Sgshapiro timeout. 438764562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 438864562Sgshapiro interface address structure when loading the system network 438964562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 439064562Sgshapiro Nanoteq. 439164562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 439264562Sgshapiro indicates the number of interfaces to read when probing 439364562Sgshapiro for hostnames and IP addresses for class w ($=w). The 439464562Sgshapiro default value is 512. Based on idea from Reinier 439564562Sgshapiro Bezuidenhout of Nanoteq. 439664562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 439764562Sgshapiro on load average. 439864562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 439964562Sgshapiro Northern Illinois University. 440064562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 440164562Sgshapiro envelope splitting has occurred. 440264562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 440364562Sgshapiro Luke Mewburn from RMIT University. 440464562Sgshapiro Add a "/quit" command to address test mode. 440564562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 440664562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 440764562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 440864562Sgshapiro Institute. 440964562Sgshapiro The contents of a class can now be copied to another class using 441064562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 441164562Sgshapiro the items in class $={Source} into the class $={Dest}. 441264562Sgshapiro Include original envelope's error transcript in bounces created for 441364562Sgshapiro split (owner-) envelopes to see the original errors when 441464562Sgshapiro the recipients were added. Based on fix from Motonori 441564562Sgshapiro Nakamura of Kyoto University. 441664562Sgshapiro Show reason for permanent delivery errors directly after the 441764562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 441864562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 441964562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 442064562Sgshapiro If the specification for the queue run interval (-q###) has a 442164562Sgshapiro syntax error, consider the error fatal and exit. 442264562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 442364562Sgshapiro noted by Motonori Nakamura of Kyoto University. 442464562Sgshapiro On operating systems which have setlogin(2), use it to set the 442564562Sgshapiro login name to the RunAsUserName when starting as a daemon. 442664562Sgshapiro This is for delivery to programs which use getlogin(). 442764562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 442864562Sgshapiro Differentiate between "command not implemented" and "command 442964562Sgshapiro unrecognized" in the SMTP dialogue. 443064562Sgshapiro Strip returns from forward and include files.

Instead, ignore the 444164562Sgshapiro ruleset lines as well. 444264562Sgshapiro Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient 444364562Sgshapiro success DSN fields as well as duplicate entries for a 444464562Sgshapiro single address due to S5 and UserDB processing. Problems 444564562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological 444664562Sgshapiro Institute. 444764562Sgshapiro Turn off timeouts when exiting sendmail due to an interrupt signal 444864562Sgshapiro to prevent the timeout from firing during the exit process. 444964562Sgshapiro Problem noted by Michael Shapiro of Sun Microsystems. 445064562Sgshapiro Do not append @MyHostName to non-RFC822 addresses output by the EXPN 445164562Sgshapiro command or on Final-Recipient: and X-Actual-Recipient: DSN 445264562Sgshapiro headers. Non-RFC822 addresses include deliveries to 445364562Sgshapiro programs, file, DECnet, etc. 445464562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 445564562Sgshapiro spoof their return address. Based on idea from Neil Rickert 445664562Sgshapiro of Northern Illinois University and patch from Per Hedeland 445764562Sgshapiro of Ericsson. 445864562Sgshapiro Report the proper UID in the bounce message if an :include: file is 445964562Sgshapiro owned by a uid that doesn't map to a username and the 446064562Sgshapiro :include: file contains delivery to a file or program. 446164562Sgshapiro Problem noted by John Beck of Sun Microsystems. 446264562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 446364562Sgshapiro the remote server responds to the first QUIT with a 4xx 446464562Sgshapiro response code and drops the connection. This behavior was 446564562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 446664562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 446764562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 446864562Sgshapiro file is not present, the lookup failure would be marked as 446964562Sgshapiro a permanent failure instead of a temporary failure. Fix 447064562Sgshapiro from Russell King of the ARM Linux Project. 447164562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 447264562Sgshapiro instead of spaces between arguments.

Problem noted by Per 450864562Sgshapiro Hedeland of Ericsson. 450964562Sgshapiro mailq displays unprintable characters in addresses as their octal 451064562Sgshapiro representation and a leading backslash. This avoids problems 451164562Sgshapiro with "unprintable" characters. Problem noted by Michal 451264562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 451364562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 451464562Sgshapiro one character past the limit. This would cause subsequent 451564562Sgshapiro hops to break the line again. The '!' is now placed in 451664562Sgshapiro the last column of the limit if the line needs to be broken. 451764562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 451864562Sgshapiro from Per Hedeland of Ericsson. 451964562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 452064562Sgshapiro resolver will fall back to TCP. However, some 452164562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 452264562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 452364562Sgshapiro don't fail on ANY queries. 452464562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 452564562Sgshapiro address, do not send an empty postmaster notification DSN 452664562Sgshapiro to the postmaster.

Suggested by Valdis Kletnieks of Virginia Tech. 486664562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 486764562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 486864562Sgshapiro new variable which identifies the root of the source 486964562Sgshapiro directories for all of the programs in the distribution. 487064562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 487164562Sgshapiro time. They can both still be overridden by setting the m4 487264562Sgshapiro macro. 487364562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 487464562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 487564562Sgshapiro build configurations, and places objects in obj.prefix.*/. 487664562Sgshapiro Complains as 'Build -f file' does for existing object 487764562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 487864562Sgshapiro Corporation. 487964562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 488064562Sgshapiro manual pages in the directory tree specified by 488164562Sgshapiro confMANROOTMAN. 488264562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 488364562Sgshapiro preformatted pages from the distribution. The new variable 488464562Sgshapiro confCOPY specifies the copying program. 488564562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 488664562Sgshapiro question. Suggested by Terry Lambert of Whistle 488764562Sgshapiro Communications. 488864562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 488964562Sgshapiro of the installed statistics and help files, respectively. 489064562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 489164562Sgshapiro operating system identity. Problem noted by Erik 489264562Sgshapiro Wachtenheim of Dartmouth College. 489364562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 489464562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 489564562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 489664562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 489764562Sgshapiro how to strip binaries. These are used by the new 489864562Sgshapiro install-strip target. 489964562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 490064562Sgshapiro the others (if it exists). 490164562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 490264562Sgshapiro then the default ones. 490390792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 490464562Sgshapiro as local delivery agent without LMTP mode, use 490564562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 490664562Sgshapiro to set the S flag. 490764562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 490864562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 490964562Sgshapiro Northern Illinois University. 491064562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 491164562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 491264562Sgshapiro the Finnish Meteorological Institute. 491364562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 491464562Sgshapiro MAILLOCK when compiling. Also requires linking with 491564562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 491664562Sgshapiro University. 491764562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 491864562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 491964562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 492064562Sgshapiro University. 492164562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 492264562Sgshapiro structure to the beginning of the program. This ensures that 492364562Sgshapiro the getservbyname() is done before any seteuid to a possibly 492464562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 492564562Sgshapiro on a Solaris system, this avoids syslog messages such as, 492664562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 492764562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 492864562Sgshapiro University. 492964562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 493064562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 493164562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 493264562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 493364562Sgshapiro characters (in LMTP mode), mail.local split the incoming 493464562Sgshapiro line up into 2046-character output lines (excluding the 493564562Sgshapiro newline). If an input line was 2047 characters long 493664562Sgshapiro (excluding CR-LF) and the last character was a '.', 493764562Sgshapiro mail.local saw it as the end of input, transfered it to the 493864562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 493964562Sgshapiro If the message was much longer, both sendmail and 494064562Sgshapiro mail.local would deadlock waiting for each other to read 494164562Sgshapiro what they have written. Problem noted by Peter Jeremy of 494264562Sgshapiro Alcatel Australia Limited. 494364562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 494464562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 494564562Sgshapiro Neil Rickert of Northern Illinois University. 494664562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 494764562Sgshapiro timeout to avoid starvation. 494864562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 494964562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 495064562Sgshapiro Infinite Monkeys & Co. 495164562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 495264562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 495364562Sgshapiro printed in a machine readable fashion and the stats file 495464562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 495564562Sgshapiro of Maryland. 495664562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 495764562Sgshapiro generated maps to the TrustedUser as specified in the 495864562Sgshapiro sendmail configuration file. 495964562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 496064562Sgshapiro configuration file to use for finding the TrustedUser 496164562Sgshapiro option. 496264562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 496364562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 496464562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 496564562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 496664562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 496764562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 496864562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 496964562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 497064562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 497164562Sgshapiro Corporation UK. 497264562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 497364562Sgshapiro (e.g., sendmail would not drop root privileges if the 497464562Sgshapiro option was specified on the command line). Problem noted 497564562Sgshapiro by Todd C. Miller of Courtesan Consulting. 497664562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 497764562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 497864562Sgshapiro Institute for Global Communications. 497964562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 498064562Sgshapiro alias file(s) if the -f option is not used. Patch from 498164562Sgshapiro John Beck of Sun Microsystems. 498264562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 498364562Sgshapiro configuration file to use for finding alias file(s). Patch 498464562Sgshapiro from John Beck of Sun Microsystems. 498564562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 498664562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 498764562Sgshapiro of the Institute for Global Communications. 498864562Sgshapiro SMRSH: Update README for the new Build system. From Tim Pierce 498964562Sgshapiro of RootsWeb Genealogical Data Cooperative. 499064562Sgshapiro VACATION: Added vacation auto-responder to sendmail distribution. 499164562Sgshapiro LIBSMDB: Added abstracted database library. Works with Berkeley 499264562Sgshapiro DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM. 499364562Sgshapiro Changed Files: 499464562Sgshapiro The Build script in the various program subdirectories are 499564562Sgshapiro no longer symbolic links. They are now scripts 499664562Sgshapiro which execute the actual Build script in 499764562Sgshapiro devtools/bin. 499864562Sgshapiro All the manual pages are now written against -man and not 499964562Sgshapiro -mandoc as they were previously. 500064562Sgshapiro Add a simple Makefile to every directory so make instead 500164562Sgshapiro of Build will work (unless parameters are 500264562Sgshapiro required for Build). 500364562Sgshapiro New Directories: 500464562Sgshapiro devtools/M4/UNIX 500564562Sgshapiro include 500664562Sgshapiro libmilter 500764562Sgshapiro libsmdb 500864562Sgshapiro libsmutil 500964562Sgshapiro vacation 501064562Sgshapiro Renamed Directories: 501164562Sgshapiro BuildTools => devtools 501264562Sgshapiro src => sendmail 501364562Sgshapiro Deleted Files: 501464562Sgshapiro cf/m4/nullrelay.m4 501564562Sgshapiro devtools/OS/Linux.ppc 501664562Sgshapiro devtools/OS/ReliantUNIX 501764562Sgshapiro devtools/OS/SINIX 501864562Sgshapiro sendmail/ldap_map.h 501964562Sgshapiro New Files: 502064562Sgshapiro INSTALL 502164562Sgshapiro PGPKEYS 502264562Sgshapiro cf/cf/generic-linux.cf 502364562Sgshapiro cf/cf/generic-linux.mc 502464562Sgshapiro cf/feature/delay_checks.m4 502564562Sgshapiro cf/feature/dnsbl.m4 502664562Sgshapiro cf/feature/generics_entire_domain.m4 502764562Sgshapiro cf/feature/no_default_msa.m4 502864562Sgshapiro cf/feature/relay_mail_from.m4 502964562Sgshapiro cf/feature/virtuser_entire_domain.m4 503064562Sgshapiro cf/mailer/qpage.m4 503164562Sgshapiro cf/ostype/bsdi.m4 503264562Sgshapiro cf/ostype/hpux11.m4 503364562Sgshapiro cf/ostype/openbsd.m4 503464562Sgshapiro contrib/bounce-resender.pl 503564562Sgshapiro contrib/domainmap.m4 503664562Sgshapiro contrib/qtool.8 503764562Sgshapiro contrib/qtool.pl 503864562Sgshapiro devtools/M4/depend/AIX.m4 503964562Sgshapiro devtools/M4/list.m4 504064562Sgshapiro devtools/M4/string.m4 504164562Sgshapiro devtools/M4/subst_ext.m4 504264562Sgshapiro devtools/M4/switch.m4 504364562Sgshapiro devtools/OS/Darwin 504464562Sgshapiro devtools/OS/GNU 504564562Sgshapiro devtools/OS/SINIX.5.43 504664562Sgshapiro devtools/OS/SINIX.5.44 504764562Sgshapiro devtools/OS/m88k 504864562Sgshapiro devtools/bin/find_in_path.sh 504964562Sgshapiro mail.local/Makefile 505064562Sgshapiro mailstats/Makefile 505164562Sgshapiro makemap/Makefile 505264562Sgshapiro praliases/Makefile 505364562Sgshapiro rmail/Makefile 505464562Sgshapiro sendmail/Makefile 505564562Sgshapiro sendmail/bf.h 505664562Sgshapiro sendmail/bf_portable.c 505764562Sgshapiro sendmail/bf_portable.h 505864562Sgshapiro sendmail/bf_torek.c 505964562Sgshapiro sendmail/bf_torek.h 506064562Sgshapiro sendmail/shmticklib.c 506164562Sgshapiro sendmail/statusd_shm.h 506264562Sgshapiro sendmail/timers.c 506364562Sgshapiro sendmail/timers.h 506464562Sgshapiro smrsh/Makefile 506564562Sgshapiro vacation/Makefile 506664562Sgshapiro Renamed Files: 506764562Sgshapiro cf/ostype/gnuhurd.m4 => cf/ostype/gnu.m4 506864562Sgshapiro sendmail/cdefs.h => include/sendmail/cdefs.h 506964562Sgshapiro sendmail/sendmail.hf => sendmail/helpfile 507064562Sgshapiro sendmail/mailstats.h => include/sendmail/mailstats.h 507164562Sgshapiro sendmail/pathnames.h => include/sendmail/pathnames.h 507264562Sgshapiro sendmail/safefile.c => libsmutil/safefile.c 507364562Sgshapiro sendmail/snprintf.c => libsmutil/snprintf.c 507464562Sgshapiro sendmail/useful.h => include/sendmail/useful.h 507564562Sgshapiro cf/ostype/solaris2.m4 => cf/ostype/solaris2.pre5.m4 507664562Sgshapiro Copied Files: 507764562Sgshapiro cf/ostype/solaris2.ml.m4 => cf/ostype/solaris2.m4 507864562Sgshapiro 507964562Sgshapiro8.9.3/8.9.3 1999/02/04 508043730Speter SECURITY: Limit message headers to a maximum of 32K bytes (total 508143730Speter of all headers in a single message) to prevent a denial of 508243730Speter service attack.

This can be used to help prevent relaying. 552138032Speter Patch from Mitchell Blank Jr of Exec-PC. 552238032Speter Mark failures for the *file* mailer and return bounce messages to the 552338032Speter sender for those failures. 552438032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 552538032Speter preserving the TZ environment variable until TimeZoneSpec 552638032Speter has been determined. Problem noted by Ralf Hildebrandt of 552738032Speter Technical University of Braunschweig. Patch from Per Hedeland 552838032Speter of Ericsson. 552938032Speter Print test input in address test mode when input is not from the tty 553064562Sgshapiro when the -v flag is given (i.e., sendmail -bt -v) to make 553138032Speter output easier to decipher. Problem noted by Aidan Nichol 553238032Speter of Procter & Gamble. 553338032Speter The LDAP map -s flag was not properly parsed and the error message 553464562Sgshapiro given included the remainder of the arguments instead of 553538032Speter solely the argument in error. Problem noted by Aidan Nichol 553638032Speter of Procter & Gamble. 553738032Speter New DontBlameSendmail option. This option allows administrators to 553838032Speter bypass some of sendmail's file security checks at the expense 553938032Speter of system security. This should only be used if you are 554038032Speter absolutely sure you know the consequences. The available 554138032Speter DontBlameSendmail options are: 554238032Speter Safe 554338032Speter AssumeSafeChown 554438032Speter ClassFileInUnsafeDirPath 554538032Speter ErrorHeaderInUnsafeDirPath 554638032Speter GroupWritableDirPathSafe 554738032Speter GroupWritableForwardFileSafe 554838032Speter GroupWritableIncludeFileSafe 554938032Speter GroupWritableAliasFile 555038032Speter HelpFileinUnsafeDirPath 555138032Speter WorldWritableAliasFile 555238032Speter ForwardFileInGroupWritableDirPath 555338032Speter IncludeFileInGroupWritableDirPath 555438032Speter ForwardFileInUnsafeDirPath 555538032Speter IncludeFileInUnsafeDirPath 555638032Speter ForwardFileInUnsafeDirPathSafe 555738032Speter IncludeFileInUnsafeDirPathSafe 555838032Speter MapInUnsafeDirPath 555938032Speter LinkedAliasFileInWritableDir 556038032Speter LinkedClassFileInWritableDir 556138032Speter LinkedForwardFileInWritableDir 556238032Speter LinkedIncludeFileInWritableDir 556338032Speter LinkedMapInWritableDir 556438032Speter LinkedServiceSwitchFileInWritableDir 556538032Speter FileDeliveryToHardLink 556638032Speter FileDeliveryToSymLink 556738032Speter WriteMapToHardLink 556838032Speter WriteMapToSymLink 556938032Speter WriteStatsToHardLink 557038032Speter WriteStatsToSymLink 557138032Speter RunProgramInUnsafeDirPath 557238032Speter RunWritableProgram 557338032Speter New DontProbeInterfaces option to turn off the inclusion of all the 557438032Speter interface names in $=w on startup. In particular, if you 557538032Speter have lots of virtual interfaces, this option will speed up 557638032Speter startup. However, unless you make other arrangements, mail 557738032Speter sent to those addresses will be bounced. 557838032Speter Automatically create alias databases if they don't exist and 557938032Speter AutoRebuildAliases is set. 558038032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 558138032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 558238032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 558338032Speter When determining the client host name ($&{client_name} macro), do 558438032Speter a forward (A) DNS lookup on the result of the PTR lookup 558538032Speter and compare results. If they differ or if the PTR lookup 558638032Speter fails, &{client_name} will contain the IP address 558764562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 558838032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 558938032Speter (i.e, it is like -ax for the temporary failure case, in 559038032Speter contrast to the success case). 559138032Speter New syntax to do limited checking of header syntax. A config line 559238032Speter of the form: 559338032Speter HHeader: $>Ruleset 559438032Speter causes the indicated Ruleset to be invoked on the Header 559538032Speter when read. This ruleset works like the check_* rulesets -- 559638032Speter that is, it can reject mail on the basis of the contents. 559738032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 559838032Speter from hiding their connection information in Received: 559938032Speter headers. 560038032Speter When SingleThreadDelivery is active, deliveries to locked hosts 560138032Speter are skipped. This will cause the delivering process to 560238032Speter try the next MX host or queue the message if no other MX 560338032Speter hosts are available. Suggested by Alexander Litvin. 560438032Speter The [FILE] mailer type now delivers to the file specified in the 560538032Speter A= equate of the mailer definition instead of $u. It also 560638032Speter obeys all of the F= mailer flags such as the MIME 560738032Speter 7/8 bit conversion flags. This is useful for defining 560838032Speter a mailer which delivers to the same file regardless of the 560964562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 561038032Speter Do not assume the identity of a remote connection is root@localhost 561138032Speter if the remote connection closes the socket before the 561238032Speter remote identity can be queried. 561338032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 561438032Speter Some mailers, including procmail, require that the real 561538032Speter uid is left unchanged by sendmail. Problem noted by Per 561638032Speter Hedeland of Ericsson. 561738032Speter No longer is the src/obj*/Makefile selected from a large list -- it 561838032Speter is now generated using the information in BuildTools/OS/ -- 561938032Speter some of the details are determined dynamically via 562038032Speter BuildTools/bin/configure.sh. 562138032Speter The other programs in the sendmail distribution -- mail.local, 562238032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 562338032Speter the new Build method which creates an operating system 562438032Speter specific Makefile using the information in BuildTools. 562538032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 562638032Speter a failure on one message won't affect future messages to the 562738032Speter same host). This is necessary if the remote host sends 562838032Speter a 451 error if the domain of the sender does not resolve 562938032Speter as is common in anti-spam configurations. Problem noted 563038032Speter by Mitchell Blank Jr of Exec-PC. 563138032Speter New "discard" mailer for check_* rulesets and header checking 563238032Speter rulesets. If one of the above rulesets resolves to the 563338032Speter $#discard mailer, the commands will be accepted but the 563438032Speter message will be completely discarded after it is accepting. 563538032Speter This means that even if only one of the recipients 563638032Speter resolves to the $#discard mailer, none of the recipients 563738032Speter will receive the mail. Suggested by Brian Kantor. 563838032Speter All but the last cloned envelope of a split envelope were queued 563938032Speter instead of being delivered. Problem noted by John Caruso 564038032Speter of CNET: The Computer Network. 564138032Speter Fix deadlock situation in persistent host status file locking. 564238032Speter Syslog an error if a user forward file could not be read due to 564338032Speter an error. Patch from John Beck of Sun Microsystems. 564438032Speter Use the first name returned on machine lookups when canonifying a 564538032Speter hostname via NetInfo. Patch from Timm Wetzel of GWDG. 564638032Speter Clear the $&{client_addr}, $&{client_name}, and $&{client_port} 564738032Speter macros when delivering a bounce message to prevent 564838032Speter rejection by a check_compat ruleset which uses these macros. 564938032Speter Problem noted by Jens Hamisch of AgiX Internetservices GmbH. 565038032Speter If the check_relay ruleset resolves to the the error mailer, the 565138032Speter error in the $: portion of the resolved triplet is used 565238032Speter in the rejection message given to the remote machine. 565338032Speter Suggested by Scott Gifford of The Internet Ramp. 565438032Speter Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros 565538032Speter before calling the check_relay ruleset. Suggested by Scott 565638032Speter Gifford of The Internet Ramp. 565738032Speter Sendmail would get a segmentation fault if a mailer exited with an 565838032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 565938032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 566038032Speter Institute. 566138032Speter Separate snprintf/vsnprintf routines into separate file for use by 566238032Speter mail.local. 566338032Speter Allow multiple map lookups on right hand side, e.g., 566438032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 566538032Speter Christophe Wolfhugel of the Pasteur Institute. 566638032Speter Properly generate success DSN messages if requested for aliases 566738032Speter which have owner- aliases. Problem noted by Kari Hurtta 566838032Speter of the Finnish Meteorological Institute. 566938032Speter Properly display delayed-expansion macros ($&{macroname}) in 567038032Speter address test mode (-bt). Problem noted by Bryan Costales 567138032Speter of InfoBeat, Inc. 567238032Speter -qR could sometimes match names incorrectly. Problem noted by 567338032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 567438032Speter Include a magic number and version in the StatusFile for the 567538032Speter mailstats command. 567638032Speter Record the number of rejected and discarded messages in the 567738032Speter StatusFile for display by the mailstats command. Patch 567838032Speter from Randall Winchester of the University of Maryland. 567938032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 568038032Speter user portion as IDENT:username@site instead of 568138032Speter username@site to differentiate the two.

Patch from Per Hedeland of 568438032Speter Ericsson. 568538032Speter Change persistent host status filename substitution so '/' is 568638032Speter replaced by ':' instead of '|' to avoid clashes. Also 568738032Speter avoid clashes with hostnames with leading dots. Fix from 568838032Speter Mitchell Blank Jr. of Exec-PC. 568938032Speter If the system lock table is full, only attempt to create a new 569038032Speter queue entry five times before giving up. Previously, it 569138032Speter was attempted indefinitely which could cause the partition 569238032Speter to run out of inodes. Problem noted by Suzie Weigand of 569338032Speter Stratus Computer, Inc. 569438032Speter In verbose mode, warn if the sendmail.cf version is less than the 569538032Speter currently supported version. 569638032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 569738032Speter from Randall S.

Patch from 574338032Speter Robert Harker of Harker Systems. 574438032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 574538032Speter directory for certain programs. 574638032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 574738032Speter local mail delivery. By the default, /usr/libexec/mail.local 574838032Speter is used. This is expected to be the mail.local shipped 574938032Speter with 8.9 which is LMTP capable. The path is based on the 575038032Speter new confEBINDIR m4 variable. 575138032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 575238032Speter FEATURE(smrsh).

To obtain the 575438032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 575538032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 575638032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 575738032Speter the user to setup different .forward files for 575838032Speter user+detail addressing. 575938032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 576038032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 576138032Speter DontProbeInterfaces, and DontBlameSendmail options. 576238032Speter CONFIG: by default do not allow relaying (that is, accepting mail 576338032Speter from outside your domain and sending it to another host 576438032Speter outside your domain). 576538032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 576638032Speter any site to any site. 576738032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 576838032Speter domain as defined by the 'm' class ($=m) to relay. 576938032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 577038032Speter the MX records of the host portion of an incoming recipient. 577138032Speter CONFIG: new FEATURE(access_db) which turns on the access database 577277349Sgshapiro feature. This database gives you the ability to allow 577338032Speter or refuse to accept mail from specified domains for 577438032Speter administrative reasons. By default, names that are listed 577538032Speter as "OK" in the access db are domain names, not host names. 577638032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 577738032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 577838032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 577938032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 578038032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 578138032Speter of FEATURE(access_db) and class 'R' to lookup individual 578238032Speter host names only. 578338032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 578438032Speter using % addressing is used, e.g. user%site@othersite, 578538032Speter and othersite is in class 'R', the check_rcpt ruleset 578638032Speter will strip @othersite and recheck user@site for relaying. 578738032Speter This feature changes that behavior. It should not be 578838032Speter needed for most installations. 578938032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 579038032Speter domain portion of the mail sender is a local host. This 579138032Speter should only be used if absolutely necessary as it opens 579238032Speter a window for spammers. Patch from Randall S. Winchester of 579338032Speter the University of Maryland. 579438032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 579538032Speter block incoming mail destined for certain recipient 579638032Speter usernames, hostnames, or addresses. 579738032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 579838032Speter refused if the host part of the argument to MAIL FROM: cannot 579938032Speter be located in the host name service (e.g., DNS). 580038032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 580138032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 580238032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 580338032Speter MAIL FROM: senders which do not include a domain. 580438032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 580538032Speter Realtime Blackhole List.

Problem noted by Kari Hurtta of the Finnish 595338032Speter Meteorological Institute. 595438032Speter If /usr/tmp/dead.letter already existed, sendmail could not 595538032Speter add additional bounces to it. Problem noted by Thomas J. 595638032Speter Arseneault of SRI International. 595738032Speter If an SMTP mailer used a non-standard port number for the outgoing 595838032Speter connection, it would be displayed incorrectly in verbose mode. 595938032Speter Problem noted by John Kennedy of Cal State University, Chico. 596038032Speter Log the ETRN parameter specified by the client before altering them 596138032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 596238032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 596338032Speter User unknown with bogus delay= values. Change them to log 596438032Speter the same as compliant addresses. Problem noted by Kari E. 596538032Speter Hurtta of the Finnish Meteorological Institute. 596638032Speter Ignore the debug resolver option unless using sendmail debug trace 596738032Speter option for resolver. Problem noted by Greg Nichols of Wind 596838032Speter River Systems. 596938032Speter If SingleThreadDelivery was enabled and the remote server returned a 597038032Speter protocol error on the DATA command, the connection would be 597138032Speter closed but the persistent host status file would not be 597238032Speter unlocked so other sendmail processes could not deliver to 597338032Speter that host. Problem noted by Peter Wemm of DIALix. 597438032Speter If queueing up a message due to an expensive mailer, don't increment 597538032Speter the number of delivery attempts or set the last delivery 597638032Speter attempt time so the message will be delivered on the next 597738032Speter queue run regardless of MinQueueAge. Problem noted by 597838032Speter Brian J. Coan of the Institute for Global Communications. 597938032Speter Authentication warnings of "Processed from queue _directory_" and 598038032Speter "Processed by _username_ with -C _filename_" would be logged 598138032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 598238032Speter of the Finnish Meteorological Institute. 598338032Speter Use a better heuristic for detecting GDBM. 598438032Speter Log null connections on dropped connections. Problem noted by 598538032Speter Jon Lewis of Florida Digital Turnpike. 598638032Speter If class dbm maps are rebuilt, sendmail will now detect this and 598738032Speter reopen the map. Previously, they could give stale 598838032Speter results during a single message processing (but would 598938032Speter recover when the next message was received). Fix from 599038032Speter Joe Pruett of Q7 Enterprises. 599138032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 599238032Speter requests. Problem noted by Kari E. Hurtta of the 599338032Speter Finnish Meteorological Institute. 599438032Speter Do not send a bounce message back to the sender regarding bad 599538032Speter recipients if the SMTP connection is dropped before the 599638032Speter message is accepted. Problem noted by Kari E. Hurtta of the 599738032Speter Finnish Meteorological Institute. 599838032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 599938032Speter sendmail via a UNIX pipe. This will allow rulesets using 600038032Speter $&{client_name} to process without sending the string through 600138032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 600238032Speter A combination of deferred delivery mode, a double bounce situation, 600338032Speter and the inability to save a bounce message to 600438032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 600538032Speter to postmaster but not remove the offending envelope from the 600638032Speter queue causing it to create a new bounce message each time the 600738032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 600838032Speter Associates. 600938032Speter Remove newlines from hostname information returned via DNS. There are 601038032Speter no known security implications of newlines in hostnames as 601138032Speter sendmail filters newlines in all vital areas; however, this 601238032Speter could cause confusing error messages. 601338032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 601438032Speter rejected if any of the specified addresses were bad. This 601538032Speter behavior was modified to only reject the bad addresses and not 601638032Speter the entire message. Problem noted by Jozsef Hollosi of 601738032Speter SuperNet, Inc. 601838032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 601938032Speter Bryan Costales of InfoBeat, Inc. 602038032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 602138032Speter mailers. Problem noted by Kari E. Hurtta of the 602238032Speter Finnish Meteorological Institute. 602338032Speter An error in calculating the available space in the list of addresses 602438032Speter for logging deliveries could cause an address to be silently 602538032Speter dropped. 602638032Speter Include the initial user environment if sendmail is restarted via 602738032Speter a HUP signal. This will give room for the process title. 602838032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 602938032Speter Mail could be delivered without a body if the machine does not 603038032Speter support flock locking and runs out of processes during 603138032Speter delivery. Fix from Chuck Lever of the University of Michigan. 603238032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 603338032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 603438032Speter Institute. 603538032Speter Make sure non-rebuildable database maps are opened before the 603664562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 603738032Speter are needed for verifying the left hand side of the aliases. 603838032Speter Problem noted by Lloyd Parkes of Victoria University. 603938032Speter Make sure sender RFC822 source route addresses are alias expanded for 604038032Speter bounce messages. Problem noted by Juergen Georgi of 604138032Speter RUS University of Stuttgart. 604238032Speter Minor lint fixes. 604338032Speter Return a temporary error instead of a permanent error if an LDAP map 604438032Speter search returns an error. This will allow sequenced maps which 604538032Speter use other LDAP servers to be checked. Fix from Booker Bense 604638032Speter of Stanford University. 604738032Speter When automatically converting from quoted printable to 8bit text do 604838032Speter not pad bare linefeeds with a space. Problem noted by Theo 604938032Speter Nolte of the University of Technology Aachen, Germany. 605038032Speter Portability: 605138032Speter Non-standard C compilers may have had a problem compiling 605238032Speter conf.c due to a standard C external declaration of 605338032Speter setproctitle(). Problem noted by Ted Roberts of 605438032Speter Electronic Data Systems. 605538032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 605638032Speter Jagielski of jaguNET Access Services. 605738032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 605838032Speter Digital UNIX: Digital UNIX (and possibly others) moves 605938032Speter loader environment variables into the loader memory 606038032Speter area. If one of these environment variables (such as 606138032Speter LD_LIBRARY_PATH) was the last environment variable, 606238032Speter an invalid memory address would be used by the process 606338032Speter title routine causing memory corruption. Problem 606438032Speter noted by Sam Hartman of Mesa Internet Systems. 606538032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 606638032Speter chownsafe() to always return 0 even if the OS does 606738032Speter not permit file giveaways. Problem noted by 606838032Speter Yasutaka Sumi of The University of Tokyo. 606964562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 607038032Speter Gerald Rinske of Siemens Business Services VAS. 607138032Speter Linux: Pad process title with NULLs. Problem noted by 607238032Speter Jon Lewis of Florida Digital Turnpike. 607338032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 607438032Speter incorrect value for the number of interfaces. 607538032Speter Problem noted by Chris Loelke of JetStream Internet 607638032Speter Services. 607738032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 607838032Speter Rinske of Siemens Business Services VAS. 607938032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 608038032Speter used on a Solaris machine. Problem noted by 608138032Speter Stephen Ma of Jtec Pty Limited. 608238032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 608338032Speter Services VAS. 608438032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 608538032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 608638032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 608738032Speter Ericsson. 608838032Speter 608964562Sgshapiro8.8.7/8.8.7 1997/08/03 609038032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 609138032Speter an exclusive lock already set -- i.e., almost all systems 609238032Speter except 4.4-BSD derived systems), the initial attempt at 609338032Speter rebuilding aliases file if the database didn't already 609438032Speter exist would fail. Patch from Raymund Will of LST Software 609538032Speter GmbH. 609638032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 609738032Speter Problem noted by Fredrik J�nsson of the Royal Institute 609838032Speter of Technology, Stockholm. 609938032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 610038032Speter some environments could give "multiple definitions" for these 610138032Speter routines during compilation. If using TCP Wrappers, assume 610238032Speter that these routines are included as though they were in the 610338032Speter C library. Patch from Robert La Ferla. 610438032Speter When a NEWDB database map was rebuilt at the same time it was being 610538032Speter used by a queue run, the maps could be left locked for the 610638032Speter duration of the queue run, causing other processes to hang. 610738032Speter Problem noted by Kendall Libby of Shore.NET. 610838032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 610938032Speter mail was passed on without any recipient header. This could 611038032Speter cause problems downstream. Problem noted by Xander Jansen 611138032Speter of SURFnet ExpertiseCentrum. 611238032Speter Give error when GDBM is used with sendmail. GDBM's locking and 611338032Speter linking of the .dir and .pag files interferes with sendmail's 611438032Speter locking and security checks. Problems noted by Fyodor 611538032Speter Yarochkin of the Kyrgyz Republic FreeNet. 611638032Speter Don't fsync qf files if SuperSafe option is not set. 611738032Speter Avoid extra calls to gethostbyname for addresses for which a 611838032Speter gethostbyaddr found no value. Also, ignore any returns 611938032Speter from gethostbyaddr that look like a dotted quad. 612038032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 612138032Speter "may be forged", since at the network level we pretty much 612238032Speter have to assume that the information is good. 612338032Speter In some cases, errors during an SMTP session could leave files 612438032Speter open or locked. 612538032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 612690792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 612738032Speter errors during testing. 612838032Speter Errors in file locking of NEWDB maps had the incorrect file name 612938032Speter printed in the error message. 613038032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 613138032Speter missing parameter were issued, the EHLO behaved like a HELO. 613238032Speter Load limiting never kicked in for incoming SMTP transactions if the 613343730Speter DeliveryMode=background and any recipient was an alias or 613438032Speter had a .forward file. From Nik Conwell of Boston University. 613538032Speter On some non-Posix systems, the decision of whether chown(2) permits 613638032Speter file giveaway was undefined. From Tetsu Ushijima of the 613738032Speter Tokyo Institute of Technology. 613838032Speter Fix race condition that could cause the body of a message to be 613938032Speter lost (so only the header was delivered). This only occurs 614038032Speter on systems that do not use flock(2), and only when a queue 614138032Speter runner runs during a critical section in another message 614238032Speter delivery. Based on a patch from Steve Schweinhart of 614338032Speter Results Computing. 614438032Speter If a qf file was found in a mail queue directory that had a problem 614538032Speter (wrong ownership, bad format, etc.) and the file name was 614638032Speter exactly MAXQFNAME bytes long, then instead of being tried 614738032Speter once, it would be tried on every queue run. Problem noted 614838032Speter by Bryan Costales of Mercury Mail. 614938032Speter If the system supports an st_gen field in the status structure, 615038032Speter include it when reporting that a file has changed after open. 615138032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 615238032Speter This out to be checked as well as reported, since it is 615338032Speter theoretically possible for an attacker to remove a file after 615438032Speter it is opened and replace it with another file that has the 615538032Speter same i-number, but some filesystems (notably AFS) return 615638032Speter garbage in this field, and hence always look like the file 615738032Speter has changed. As a practical matter this is not a security 615838032Speter problem, since the files can be neither hard nor soft links, 615938032Speter and on no filesystem (that I am aware of) is it possible to 616038032Speter have two files on the same filesystem with the same i-number 616138032Speter simultaneously. 616238032Speter Delete the root Makefile from the distribution -- it is only for 616338032Speter use internally, and does not work at customer sites. 616438032Speter Fix botch that caused the second MAIL FROM: command in a single 616538032Speter transaction to clear the entire transaction. Problem 616638032Speter noted by John Kennedy of Cal State University, Chico. 616738032Speter Work properly on machines that have _PATH_VARTMP defined without 616838032Speter a trailing slash. (And a pox on vendors that decide to 616938032Speter ignore the established conventions!) Problem noted by 617038032Speter Gregory Neil Shapiro of WPI. 617138032Speter Internal changes to make it easier to add another protocol family 617238032Speter (intended for IPv6). Patches are from John Kennedy of 617338032Speter CSU Chico. 617438032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 617538032Speter an extra space at the beginning of some lines. Problem 617638032Speter noted by Charles Karney of Princeton University; fix based 617738032Speter on a patch from Christophe Wolfhugel. 617838032Speter Portability: 617938032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 618038032Speter with the _Sendmail_ book, 2nd edition. Note that 618138032Speter the book is actually wrong: _PATH_SENDMAILCF should 618238032Speter be used instead. 618338032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 618438032Speter of Argonne National Laboratory. 618538032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 618638032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 618738032Speter SunOS: Include <memory.h> to fix warning from util.c. From 618838032Speter James Aldridge of EUnet Ltd. 618938032Speter Solaris: Change STDIR (location of status file) to /etc/mail 619038032Speter in Makefiles. 619138032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 619238032Speter Makefiles. Use NEWDB on Linux instead. 619338032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 619438032Speter exists but behaves differently than other OSes. 619538032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 619638032Speter around the problem. Problem noted by Tom Moore of 619738032Speter NCR Corp. 619838032Speter HP-UX 9.x: fix compile warnings for old select API.

This makes it possible to create a root 625138032Speter owned file in an arbitrary directory by inserting the symlink 625238032Speter into a writable directory after the initial lstat(2) check 625338032Speter determined that the file did not exist. The only verified 625438032Speter example of a system having these odd semantics for O_EXCL 625538032Speter and symbolic links was HP-UX prior to version 9.07. Most 625638032Speter systems do not have the problem, since a exclusive create 625738032Speter of a file disallows symbolic links. Systems that have been 625838032Speter verified to NOT have the problem include AIX 3.x, *BSD, 625938032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 626038032Speter and Ultrix. This is a potential exposure on systems that 626138032Speter have this bug and which do not have a MAILER-DAEMON alias 626238032Speter pointing at a legitimate account, since this will cause old 626338032Speter mail to be dropped in /var/tmp/dead.letter. 626438032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 626538032Speter if maps or alias files are in world writable directories. 626638032Speter If your system has alias maps in writable directories, it 626738032Speter is potentially possible for an attacker to replace the .db 626838032Speter (or .dir and .pag) files by symbolic links pointing at 626938032Speter another database; this can be used either to expose 627038032Speter information (e.g., by pointing an alias file at /etc/spwd.db 627138032Speter and probing for accounts), or as a denial-of-service attack 627238032Speter (by trashing the password database). The fix disallows 627338032Speter symbolic links entirely when rebuilding alias files or on 627438032Speter maps that are in writable directories, and always warns on 627538032Speter writable directories; 8.9 will probably consider writable 627638032Speter directories to be fatal errors. This does not represent an 627738032Speter exposure on systems that have alias files in unwritable 627838032Speter system directories. 627938032Speter SECURITY: disallow .forward or :include: files that are links (hard 628038032Speter or soft) if the parent directory (or any directory in the 628138032Speter path) is writable by anyone other than the owner. This is 628238032Speter similar to the previous case for user files. This change 628338032Speter should not affect most systems, but is necessary to prevent 628438032Speter an attacker who can write the directory from pointing such 628538032Speter files at other files that are readable only by the owner. 628638032Speter SECURITY: Tighten safechown rules: many systems will say that they 628738032Speter have a safe (restricted to root) chown even on files that 628838032Speter are mounted from another system that allows owners to give 628938032Speter away files. The new rules are very strict, trusting file 629038032Speter ownership only in those few cases where the system has 629138032Speter been verified to be at least as paranoid as necessary. 629238032Speter However, it is possible to relax the rules to partially 629338032Speter trust the ownership if the directory path is not world or 629438032Speter group writable. This might allow someone who has a legitimate 629538032Speter :include: file (referenced directly from /etc/aliases) to 629638032Speter become another non-root user if the :include: file is in a 629738032Speter non-writable directory on an NFS-mounted filesystem where 629838032Speter the local system says that giveaway is denied but it is 629938032Speter actually permitted. I believe this to be a very small set 630038032Speter of cases. If in doubt, do not point :include: aliases at 630138032Speter NFS-mounted filesystems. 630238032Speter SECURITY: When setting a numeric group id using the RunAsUser option 630338032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 630438032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 630538032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 630638032Speter The user id was still set properly. Problem noted by Uli 630738032Speter Pralle of the Technical University of Berlin. 630838032Speter Save the initial gid set for use when checking for if the 630938032Speter PrivacyOptions=restrictmailq option is set. Problem reported 631038032Speter by Wolfgang Ley of DFN-CERT. 631138032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 631238032Speter failure on one message won't affect future messages to the 631338032Speter same host). 631438032Speter IP source route printing had an "off by one" error that would 631538032Speter affect any options that came after the route option. Patch 631638032Speter from Theo de Raadt. 631738032Speter The "Message is too large" error didn't successfully bounce the error 631838032Speter back to the sender. Problem reported by Stephen More of 631938032Speter PSI; patch from Gregory Neil Shapiro of WPI. 632038032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 632138032Speter of 5.1.3); it apparently gets used in multiple ways. 632238032Speter Suggested by John Myers of Portola Communications. 632338032Speter Fix possible extra null byte generated during collection if errors 632438032Speter occur at the beginning of the stream. Patch contributed by 632538032Speter Andrey A. Chernov and Gregory Neil Shapiro. 632638032Speter Code changes to avoid possible reentrant call of malloc/free within 632738032Speter a signal handler. Problem noted by John Beck of Sun 632838032Speter Microsystems. 632938032Speter Move map initialization to be earlier so that check_relay ruleset 633038032Speter will have the latest version of the map data. Problem noted 633138032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 633238032Speter If there are fatal errors during the collection phase (e.g., message 633338032Speter too large) don't send the bogus message. 633438032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 633538032Speter have errors and have owner- aliases. Problem noted by Michael 633638032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 633738032Speter Avoid null pointer dereference on illegal Boundary= parameters in 633838032Speter multipart/mixed Content-Type: header. Problem noted by 633938032Speter Richard Muirden of RMIT University. 634038032Speter Always print error messages during newaliases (-bi) even if the 634138032Speter ErrorMode is not set to "print". Fix from Gregory Neil 634238032Speter Shapiro. 634338032Speter Test mode could core dump if you did a /map lookup in an optional map 634438032Speter that could not be opened. Based on a fix from John Beck of 634538032Speter Sun Microsystems. 634638032Speter If DNS is misconfigured so that the last MX record tried points to 634738032Speter a host that does not have an A record, but other MX records 634838032Speter pointed to something reasonable, don't bounce the message 634938032Speter with a "host unknown" error. Note that this should really 635038032Speter be fixed in the zone file for the domain. Problem noted by 635138032Speter Joe Rhett of Navigist, Inc. 635238032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 635338032Speter the message as having been tried; otherwise the next queue 635438032Speter run will not realize that this is a second attempt and will 635538032Speter retry immediately. Problem noted by Bryan Costales of 635638032Speter Mercury Mail. 635738032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 635838032Speter will be run until the later setting of the clock is reached. 635938032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 636038032Speter Morgan Stanley. 636138032Speter If the load average rises above the cutoff threshold (above which 636238032Speter sendmail will not process the queue at all) during a queue 636338032Speter run, abort the queue run immediately. Problem noted by 636438032Speter Bryan Costales of Mercury Mail. 636538032Speter The variable queue processing algorithm (based on the message size, 636638032Speter number of recipients, message precedence, and job age) was 636738032Speter non-functional -- either the entire queue was processed or 636838032Speter none of the queue was processed. The updated algorithm 636938032Speter does no queue run if a single recipient zero size job will 637038032Speter not be run. 637138032Speter If there is a fatal ("panic") message that will cause sendmail to 637238032Speter die immediately, never hold the error message for future 637338032Speter printing. 637438032Speter Force ErrorMode=print in -bt mode so that all errors are printed 637538032Speter regardless of the setting of the ErrorMode option in the 637638032Speter configuration file. Patch from Gregory Neil Shapiro. 637738032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 637838032Speter routine available in one of the libraries. Use it in conf.h. 637938032Speter The -m (match only) flag now works on host class maps. 638038032Speter If class hash or btree maps are rebuilt, sendmail will now detect 638138032Speter this and reopen the map. Previously, they could give 638238032Speter erroneous results during a single message processing 638338032Speter (but would recover when the next message was received). 638438032Speter Don't delete zero length queue files when doing queue runs until the 638538032Speter files are at least ten minutes old. This avoids a potential 638638032Speter race condition: the creator creates the qf file, getting back 638738032Speter a file descriptor. The queue runner locks it and deletes it 638838032Speter because it is zero length. The creator then writes the 638938032Speter descriptor that is now for a disconnected file, and the 639038032Speter job goes away. Based on a suggestion by Bryan Costales. 639138032Speter When determining the "validated" host name ($_ macro), do a forward 639238032Speter (A) DNS lookup on the result of the PTR lookup and compare 639338032Speter results. If they differ or if the PTR lookup fails, tag the 639438032Speter address as "may be forged". 639538032Speter Log null connections (i.e., hosts that connect but do not do any 639638032Speter substantive activity on the connection before disconnecting; 639738032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 639838032Speter Always permit "writes" to /dev/null regardless of the link count. 639938032Speter This is safe because /dev/null is special cased, and no open 640038032Speter or write is ever actually attempted. Patch from Villy Kruse 640138032Speter of TwinCom. 640238032Speter If a message cannot be sent because of a 552 (exceeded storage 640338032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 640438032Speter was given, don't return the body in the bounce, since there 640538032Speter is a very good chance that the message will double-bounce. 640638032Speter Fix possible line truncation if a quoted-printable had an =00 escape 640738032Speter in the body. Problem noted by Charles Karney of the Princeton 640838032Speter Plasma Physics Laboratory. 640938032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 641038032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 641138032Speter Institute. 641238032Speter The MaxDaemonChildren option wasn't applying to queue runs as 641338032Speter documented. Note that this increases the potential denial 641438032Speter of service problems with this option: an attacker can 641538032Speter connect many times, and thereby lock out queue runs as well 641638032Speter as incoming connections. If you use this option, you should 641738032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 641838032Speter to avoid this attack. Failure to limit noted by Matthew 641938032Speter Dillon of BEST Internet Communications. 642038032Speter Always give a message in newaliases if alias files cannot be 642138032Speter opened instead of failing silently. Suggested by Gregory 642238032Speter Neil Shapiro. This change makes the code match the O'Reilly 642338032Speter book (2nd edition). 642438032Speter Some older versions of the resolver could return with h_errno == -1 642538032Speter if no name server could be reached, causing mail to bounce 642638032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 642738032Speter John Beck of SunSoft. 642838032Speter If a :include: file is owned by a user that does not have an entry 642938032Speter in the passwd file, sendmail could dereference a null pointer. 643038032Speter Problem noted by Satish Mynam of Sun Microsystems. 643138032Speter Take precautions to make sure that the SMTP protocol cannot get out 643238032Speter of sync if (for example) an alias file cannot be opened. 643338032Speter Fix a possible race condition that can cause a SIGALRM to come in 643438032Speter immediately after a SIGHUP, causing the new sendmail to die. 643538032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 643638032Speter from Villy Kruse of TwinCom. 643738032Speter Ignore improperly formatted SMTP reply codes. Previously these were 643838032Speter partially processed, which could cause confusing error 643938032Speter returns. 644038032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 644138032Speter on some architectures. 644238032Speter Portability: 644338032Speter A/UX: from Jim Jagielski of NASA/GSFC. 644438032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 644538032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 644638032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 644738032Speter defined. Problem reported by A Sun of the University 644838032Speter of Washington. 644938032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 645038032Speter the system rather than guessing at compile time. 645138032Speter Patch contributed by John Beck of Sun Microsystems. 645238032Speter Intel Paragon: from Wendy Lin of Purdue University. 645338032Speter GNU Hurd: from Miles Bader of the GNU project. 645438032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 645538032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 645638032Speter Unfortunately releasing them opens a race condition, 645738032Speter but there appears to be no fix for this. Patch from 645838032Speter Gregory Neil Shapiro. 645938032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 646038032Speter Solaris: a bug in strcasecmp caused characters with the 646138032Speter high order bit set to apparently randomly match 646238032Speter letters -- for example, $| (0233) matches "i" and "I". 646338032Speter Problem noted by John Gregson of the University of 646438032Speter Cambridge. 646538032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 646638032Speter Kari Hurtta. 646738032Speter IRIX 6.x: Create Makefiles for systems that claim to be 646838032Speter IRIX64 but are 6.2 or higher (so use the regular 646938032Speter IRIX Makefile). 647038032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 647138032Speter Problem noted by Eric Hagberg of Morgan Stanley. 647238032Speter CONFIG: Some canonification was still done for UUCP-like addresses 647338032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 647438032Speter Brian Candler. 647538032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 647638032Speter local names as local. Problem noted by Jeff Polk of BSDI; 647738032Speter fix provided by Gregory Neil Shapiro. 647838032Speter CONFIG: The "local:user" syntax entries in mailertables and other 647938032Speter "mailer:user" syntax locations returned an incorrect value 648038032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 648138032Speter CONFIG: Retain "+detail" information when forwarding mail to a 648238032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 648338032Speter Guenther of Gustavus Adolphus College. 648438032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 648538032Speter rules are the same as for aliasing. Based on a patch from 648638032Speter Gregory Neil Shapiro. 648738032Speter CONFIG: Break up parsing rules into several pieces; this should 648838032Speter have no functional change in this release, but makes it 648938032Speter possible to have better anti-spam rulesets in the future. 649038032Speter CONFIG: Disallow double dots in host names to avoid having the 649138032Speter HostStatusDirectory store status under the wrong name. 649238032Speter In some cases this can be used as a denial-of-service attack. 649338032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 649438032Speter Gregory Neil Shapiro. 649538032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 649638032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 649738032Speter don't include From_, and convert to 8-bit). Suggestions 649838032Speter from Kimmo Suominen and Roderick Schertler. 649964562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 650038032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 650138032Speter was specified, even when it wasn't. 650238032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 650338032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 650438032Speter "slip in" a symbolic link between the lstat(2) call and the 650538032Speter exclusive open. This is only a problem on System V derived 650638032Speter systems that allow an exclusive create on files that are 650738032Speter symbolic links pointing nowhere. 650838032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 650938032Speter not reset back to root, which on some systems would cause 651038032Speter later mailboxes to fail. Also, any partial message would 651138032Speter not be truncated, which could result in repeated deliveries. 651238032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 651338032Speter developers). 651438032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 651538032Speter change to the sendmail map code was made in 8.8.3. Problem 651638032Speter noted by Gregory Neil Shapiro. 651738032Speter MAKEMAP: Give warnings on file problems such as map files that are 651890792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 651938032Speter often run as root and hence has the potential for the same 652038032Speter sorts of problems as alias rebuilds. 652138032Speter MAKEMAP: Change compilation so that it will link properly on 652238032Speter NEXTSTEP. 652338032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 652438032Speter Accept an optional list of arguments following the server 652538032Speter name for the ETRN arguments to use (instead of $=w).

This 652938032Speter Perl script converts GECOS information in the /etc/passwd 653038032Speter file into aliases, allowing for faster access to full name 653138032Speter lookups; it is also clever about adding aliases (to root) 653238032Speter for system accounts. 653338032Speter NEW FILES: 653438032Speter src/safefile.c 653538032Speter cf/ostype/gnuhurd.m4 653638032Speter cf/ostype/irix6.m4 653738032Speter contrib/passwd-to-alias.pl 653838032Speter src/Makefiles/Makefile.IRIX64.6.1 653938032Speter src/Makefiles/Makefile.IRIX64.6.x 654038032Speter RENAMED FILES: 654138032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 654238032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 654338032Speter 654464562Sgshapiro8.8.5/8.8.5 1997/01/21 654538032Speter SECURITY: Clear out group list during startup. Without this, sendmail 654638032Speter will continue to run with the group permissions of the caller, 654738032Speter even if RunAsUser is specified. 654838032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 654938032Speter to any known attack, but it's best to be conservative. 655038032Speter Suggested by Peter Wemm of DIALix. 655138032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 655238032Speter security implications. Patch from Alex Garthwaite of the 655338032Speter University of Pennsylvania. 655438032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 655538032Speter would truncate the address after "Full". Although the -f 655638032Speter syntax is incorrect (since it is in the envelope, it 655738032Speter shouldn't have comments and full names), the failure mode 655838032Speter was unnecessarily awful. 655938032Speter Fix a possible null pointer dereference when converting 8-bit data 656038032Speter to a 7-bit format. Problem noted by Jim Hutchins of 656138032Speter Sandia National Labs and David James of British Telecom. 656238032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 656338032Speter runs. Although this really shouldn't be used (F=9 is for 656438032Speter final delivery only, and using it on an SMTP mailer makes 656538032Speter it possible for a message to be converted from 8->7->8->7 656638032Speter bits several times), it shouldn't have failed with a syserr. 656738032Speter Problem noted by Eric Hagberg of Morgan Stanley. 656838032Speter _Really_ fix the multiple :maildrop code in the user database 656938032Speter module. Patch from Roy Mongiovi of Georgia Tech. 657038032Speter Let F lines in the configuration file actually read root-only 657138032Speter files if the configuration file is safe. Based on a 657238032Speter patch from Keith Reynolds of SCO. 657338032Speter ETRN followed by QUIT would hold the connection open until the queue 657438032Speter run completed. Problem noted by Truck Lewis of TDK 657538032Speter Semiconductor Corp. 657638032Speter It turns out that despite the documentation, the TCP wrappers library 657738032Speter does _not_ log rejected connections. Do the logging ourselves. 657838032Speter Problem noted by Fletcher Mattox of the University of Texas 657938032Speter at Austin. 658038032Speter If sendmail finds a qf file in its queue directory that is an unknown 658138032Speter version (e.g., when backing out to an old version), the 658238032Speter error is reported on every queue run. Change it to only 658338032Speter give the error once (and rename the qf => Qf). Patch from 658438032Speter William A. Gianopoulos of Raytheon Company. 658538032Speter Start a new session when doing background delivery; currently it 658638032Speter ignored signals but didn't start a new signal, that caused 658738032Speter some problems if a background process tried to send mail 658838032Speter under certain circumstances. Problem noted by Eric Hagberg 658938032Speter of Morgan Stanley; fix from Kari Hurtta. 659038032Speter Simplify test for skipping a queue run to just check if the current 659138032Speter load average is >= the queueing load average. Previously 659238032Speter the check factored in some other parameters that caused it 659338032Speter to essentially never skip the queue run. Patch from Bryan 659438032Speter Costales. 659538032Speter If the SMTP server is running in "nullserver" mode (that is, it is 659638032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 659738032Speter (25) commands; this helps prevent a bad guy from putting 659838032Speter you into a tight loop as a denial-of-service attack. Based 659938032Speter on an e-mail conversation with Brad Knowles of AOL. 660038032Speter Slow down when too many "light weight" commands have been issued; 660138032Speter this helps prevent a class of denial-of-service attacks. 660238032Speter The current values and defaults are: 660338032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 660438032Speter MAXHELOCOMMANDS 3 HELO, EHLO 660538032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 660638032Speter MAXETRNCOMMANDS 8 ETRN 660738032Speter These will probably be configurable in a future release. 660838032Speter On systems that have uid_t typedefed to be an unsigned short, programs 660938032Speter that had the F=S flag and no U= equate would be invoked with 661038032Speter the real uid set to 65535 rather than being left unchanged. 661138032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 661238032Speter by Steve Hubert of the University of Washington, Seattle. 661338032Speter Mail that was Quoted-Printable encoded and had a soft line break on 661438032Speter the last line (i.e., an incomplete continuation) had the last 661538032Speter line dropped. Since this appears to be illegal it isn't 661638032Speter clear what to do with it, but flushing the last line seems 661738032Speter to be a better "fail soft" approach. Based on a patch from 661838032Speter Eric Hagberg. 661938032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 662038032Speter bogus HELO command still causes the "Polite people say HELO 662138032Speter first" error message. Problem pointed out by Chris Thomas 662238032Speter of UCLA; patch from John Beck of SunSoft. 662338032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 662471345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 662571345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 662671345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 662738032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 662838032Speter in a DATA transaction to be sticky; these can occur because 662938032Speter a message is too large, and smaller messages should still go 663038032Speter through. Problem noted by Matt Dillon of Best Internet 663138032Speter Communications. 663238032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 663338032Speter had been successfully delivered to the envelope sender. 663438032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 663538032Speter Gregory Neil Shapiro of WPI. 663638032Speter Give better diagnostics on long alias lines. Based on code contributed 663738032Speter by Patrick Gosling of the University of Cambridge. 663838032Speter Increase the number of virtual interfaces that will be probed for 663938032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 664038032Speter PORTABILITY: 664138032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 664238032Speter Toshiaki Nomura of Fujitsu Limited. 664338032Speter SunOS with LDAP support: compile problems with struct timeval. 664438032Speter Patch from Nick Cuccia of TCSI Corporation. 664538032Speter SCO: from Keith Reynolds of SCO. 664638032Speter Solaris: kstat load average computation wasn't being used. 664738032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 664838032Speter (Moscow). 664938032Speter OpenBSD: from Jason Downs of teeny.org. 665038032Speter Altos System V: from Tim Rice. 665138032Speter Solaris 2.5: from Alan Perry of SunSoft. 665238032Speter Solaris 2.6: from John Beck of SunSoft. 665338032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 665438032Speter of Pratt & Whitney <miorelli@pweh.com>. 665538032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 665638032Speter _just_right_ yet. Tweak it again. I'll omit the names 665738032Speter of the "contributors" (quantity two) in this one case. 665838032Speter As of now, NO MORE DISCUSSION about the syntax of the 665938032Speter Received: line. 666038032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 666138032Speter it never inserts that class into the output file. Fix it 666238032Speter so it will honor EXPOSED_USER but will _not_ include root 666338032Speter automatically in this class. Problem noted by Ronan KERYELL 666438032Speter of Centre de Recherche en Informatique de l'�cole Nationale 666538032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 666638032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 666738032Speter such as LUSER_RELAY. This change permits the following 666838032Speter syntaxes: ``local:'' will send to the same user on the 666938032Speter local machine (e.g., in a mailertable entry for "host", 667038032Speter ``local:'' will cause an address addressed to user@host to 667138032Speter go to user on the local machone). ``local:user'' will send 667238032Speter to the named user on the local machine. ``local:user@host'' 667338032Speter is equivalent to ``local:user'' (the host is ignored). In 667438032Speter all cases, the original user@host is passed in $@ (i.e., the 667538032Speter detail information). Inspired by a report from Michael Fuhr. 667638032Speter CONFIG: Strip quotes from the first word of an "error:" host 667738032Speter indication. This lets you set (for example) the LUSER_RELAY 667838032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 667938032Speter of the \" so that the resulting string is properly quoted. 668038032Speter Problem noted by Gregory Neil Shapiro of WPI. 668138032Speter OP.ME: documentation was inconsistent about whether sendmail did a 668238032Speter NOOP or a RSET to probe the connection (it does a RSET). 668338032Speter Inconsistency noted by Deeran Peethamparam. 668438032Speter OP.ME: insert additional blank pages so it will print properly on 668538032Speter a duplex printer. From Matthew Black of Cal State University, 668638032Speter Long Beach. 668738032Speter 668864562Sgshapiro8.8.4/8.8.4 1996/12/02 668938032Speter SECURITY: under some circumstances, an attacker could get additional 669038032Speter permissions by hard linking to files that were group 669138032Speter writable by the attacker. The solution is to disallow any 669238032Speter files that have hard links -- this will affect .forward, 669338032Speter :include:, and output files. Problem noted by Terry 669438032Speter Kyriacopoulos of Interlog Internet Services. As a 669538032Speter workaround, set UnsafeGroupWrites -- always a good idea. 669638032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 669738032Speter is, it is possible to do a denial-of-service attack on 669838032Speter MX hosts that rely on the use of the null MX list. There 669938032Speter is no danger if you have this option turned off (the default). 670038032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 670138032Speter unsafe. I know of no specific attack against this, although 670238032Speter a denial-of-service attack is probably possible, but in theory 670338032Speter you should not be able to safely tweak anything that affects 670438032Speter the permissions that are used when mail is delivered. 670538032Speter Purgestat could go into an infinite loop if one of the host status 670638032Speter directories somehow became empty. Problem noted by Roy 670738032Speter Mongiovi of Georgia Tech. 670838032Speter Processes got "lost" when counting children due to a race condition. 670938032Speter This caused "proc_list_probe: lost pid" messages to be logged. 671038032Speter Problem noted by several people. 671138032Speter On systems with System V SIGCLD child signal semantics (notably AIX 671238032Speter and HP-UX), mail transactions would print the message "451 671338032Speter SMTP-MAIL: lost child: No child processes". Problem noted 671438032Speter by several people. 671538032Speter Miscellaneous compiler warnings on picky compilers (or when setting 671638032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 671738032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 671838032Speter not be persistent between runs, since they are based on the 671938032Speter message rather than the host. Problem noted by Matt Dillon 672038032Speter of Best Internet Communications. 672138032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 672238032Speter of NCR (a.k.a., AT&T Global Information Solutions). 672338032Speter Avoid the possibility of having a child daemon run to completion 672438032Speter (including closing the SMTP socket) before the parent has 672538032Speter had a chance to close the socket; this can cause the parent 672638032Speter to hang for a long time waiting for the socket to drain. 672738032Speter Patch from Don Lewis of TDK Semiconductor. 672838032Speter If the fork() failed in a queue run, the queue runners would not be 672938032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 673038032Speter Some error conditions in ETRN could cause output without an SMTP 673138032Speter status code. Problem noted by Don Lewis. 673238032Speter Multiple :maildrop addresses in the user database didn't work properly. 673338032Speter Patch from Roy Mongiovi of Georgia Tech. 673438032Speter Add ".db" automatically onto any user database spec that does not 673538032Speter already have it; this is for consistency with makemap, the 673638032Speter K line, and the documentation. Inconsistency pointed out 673738032Speter by Roy Mongiovi. 673838032Speter Allow sendmail to be properly called in nohup mode. Patch from 673938032Speter Kyle Jones of UUNET. 674038032Speter Change ETRN to ignore but still update host status files; previously 674138032Speter it would ignore them and not save the updated status, which 674238032Speter caused stale information to be maintained. Based on a patch 674338032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 674438032Speter ETRN ignore the MinQueueAge option. 674538032Speter Patch long term host status to recover more gracefully from an empty 674638032Speter host status file condition. Patch from NAKAMURA Motonori 674738032Speter of Kyoto University. 674838032Speter Several patches to signal handling code to fix potential race 674938032Speter conditions from Don Lewis. 675038032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 675138032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 675238032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 675338032Speter compile flag; use NETINET instead. Solution based on a 675438032Speter patch from Bryan Costales. 675538032Speter PORTABILITY FIXES: 675638032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 675738032Speter /etc/security/passwd file when called as root. This 675838032Speter is very slow on some systems. To speed it up, use the 675938032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 676038032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 676138032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 676238032Speter Glicker of Burrelle's Information Service. 676338032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 676438032Speter from Makoto MATSUSHITA of Osaka University. 676538032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 676638032Speter Leeds University and SASABE Tetsuro of the University 676738032Speter of Tokyo. 676838032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 676938032Speter Services, Inc. 677038032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 677138032Speter I believe this to have only been a problem if you 677238032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 677338032Speter to stick with /etc/sendmail.cf as your One True Path. 677438032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 677538032Speter Martin Laubach of the Technischen Universit�t Wien. 677638032Speter CONFIG: change default Received: line to be multiple lines rather 677738032Speter than one long one. By popular demand. 677838032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 677938032Speter from Jerome Berkman of U.C. Berkeley. 678038032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 678138032Speter to take a very long time. Problem noted by Yoshiro YONEYA 678238032Speter of NTT Software Corporation. 678338032Speter CONTRIB: add etrn.pl, contributed by John Beck. 678438032Speter NEW FILES: 678538032Speter contrib/etrn.pl 678638032Speter 678764562Sgshapiro8.8.3/8.8.3 1996/11/17 678838032Speter SECURITY: it was possible to get a root shell by lying to sendmail 678938032Speter about argv[0] and then sending it a signal. Problem noted 679038032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 679138032Speter best-of-security list. 679238032Speter Log sendmail binary version number in "Warning: .cf version level 679338032Speter (%d) exceeds program functionality (%d) message" -- this 679438032Speter should make it clearer to people that they are running 679538032Speter the wrong binary. 679638032Speter Fix a problem that occurs when you open an SMTP connection and then 679738032Speter do one or more ETRN commands followed by a MAIL command; at 679838032Speter the end of the DATA phase sendmail would incorrectly report 679938032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 680038032Speter noted by Eric Bishop of Virginia Tech. 680138032Speter When doing text-based host canonification (typically /etc/hosts 680238032Speter lookup), a null host name would match any /etc/hosts entry 680338032Speter with space at the end of the line. Problem noted by Steve 680438032Speter Hubert of the University of Washington, Seattle. 680538032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 680638032Speter Problem reported by Tom Smith of Digital Equipment Corp. 680738032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 680838032Speter size PACKETSZ (512) is not sufficient for some nameserver 680938032Speter answers containing very many resource records. The resolver 681038032Speter may also switch to TCP and retry if it detects UDP packet 681138032Speter overflow. Also, allow for the fact that the resolver 681238032Speter routines res_query and res_search return the size of the 681338032Speter *un*truncated answer in case the supplied answer buffer it 681438032Speter not big enough to accommodate the entire answer. Patch from 681538032Speter Eric Wassenaar. 681638032Speter Improvements to MaxDaemonChildren code. If you think you have too 681738032Speter many children, probe the ones you have to verify that they 681838032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 681938032Speter Also, do this probe before growing the vector of children 682038032Speter pids; this previously caused the vector to grow indefinitely 682138032Speter due to a race condition. Problem reported by Kyle Jones of 682238032Speter UUNET. 682338032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 682438032Speter O_EXLOCK to zero; this fools the map compilation code into 682538032Speter thinking that it can avoid race conditions by locking on open. 682638032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 682738032Speter Leif Erlingsson of Data Lege. 682838032Speter Always call res_init() on startup (if compiled in, of course) to 682938032Speter allow the sendmail.cf file to tweak resolver flags; without 683038032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 683138032Speter Andrew Sun of Merrill Lynch. 683238032Speter Improvements to host status printing code. Suggested by Steve Hubert 683338032Speter of the University of Washington, Seattle. 683438032Speter Change MinQueueAge option processing to do the check for the job age 683538032Speter when reading the queue file, rather than at the end; this 683638032Speter avoids parsing the addresses, which can do DNS lookups. 683738032Speter Problem noted by John Beck of InReference, Inc. 683838032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 683938032Speter properly escaped. Problem noted by Peter Nilsson of the 684038032Speter University of Linkoping. 684138032Speter In some cases, sendmail would retain root permissions during queue 684238032Speter runs even if RunAsUser was set. Problem noted by Mark 684338032Speter Thomas of Mark G. Thomas Consulting. 684438032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 684538032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 684638032Speter the envelope, and the receiving SMTP server speaks DSN, then 684738032Speter the DSN would be both generated locally and propagated to the 684838032Speter other end. 684938032Speter The U= mailer field didn't correctly extract the group id if the 685038032Speter user id was numeric. Problem noted by Kenneth Herron of 685138032Speter MCI Telecommunications Communications. 685238032Speter If a message exceeded the fixed maximum size on input, the body of 685338032Speter the message was included in the bounce. Note that this did 685438032Speter not occur if it exceeded the maximum _output_ size. Problem 685538032Speter reported by Kyle Jones of UUNET. 685638032Speter PORTABILITY FIXES: 685738032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 685838032Speter AIX4 defines to use seteuid(2) instead, which 685938032Speter works on 4.1 as well as 4.2. Problem noted by 686038032Speter H�kan Lindholm of interAF, Sweden. 686138032Speter AIX4: use tzname[] vector to determine time zone name. 686238032Speter Patch from NAKAMURA Motonori of Kyoto University. 686338032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 686438032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 686538032Speter Solaris: kstat(3k) support for retrieving the load average. 686638032Speter This adds the LA_KSTAT definition for LA_TYPE. 686738032Speter The outline of the implementation was contributed 686838032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 686938032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 687038032Speter declaration of struct rusage at the top of conf.h; 687138032Speter change it to only be included if you are using gcc, 687238032Speter which is apparently the only compiler that requires 687338032Speter it in the first place. Problem noted by Jeff 687438032Speter Earickson of Colby College. 687538032Speter IRIX: don't default to using gcc. IRIX is a civilized 687638032Speter operating system that comes with a decent compiler 687738032Speter by default. Problem noted by Barry Bouwsma and 687838032Speter Kari Hurtta. 687938032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 688038032Speter consistency with other local mailers. Inconsistency 688138032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 688238032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 688338032Speter overhead) as part of the bestmx_is_local feature, the 688438032Speter domain part was dropped from the name. Patch from Steve 688538032Speter Hubert of the University of Washington, Seattle. 688638032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 688738032Speter end up being translated to the null host name, which would 688838032Speter return any entry in /etc/hosts that had a space at the end 688938032Speter of the line. Problem noted by Steve Hubert of the 689038032Speter University of Washington, Seattle. 689138032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 689238032Speter Polytechnic Institute. 689338032Speter MAKEMAP: tweak hash and btree parameters for better performance. 689438032Speter Patch from Matt Dillon of Best Internet Communications. 689538032Speter NEW FILES: 689638032Speter src/Makefiles/Makefile.Linux.ppc 689738032Speter cf/ostype/aix4.m4 689838032Speter cf/ostype/mklinux.m4 689938032Speter 690064562Sgshapiro8.8.2/8.8.2 1996/10/18 690138032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 690238032Speter changed the code but didn't fix the problem. 690338032Speter PORTABILITY FIXES: 690438032Speter Solaris: Don't use the system getusershell(3); it can 690538032Speter apparently corrupt the heap in some circumstances. 690638032Speter Problem found by Ken Pizzini of Spry, Inc. 690738032Speter OP.ME: document several mailer flags that were accidentally omitted 690838032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 690938032Speter CONFIG: no changes. 691038032Speter 691164562Sgshapiro8.8.1/8.8.1 1996/10/17 691238032Speter SECURITY: unset all environment variables that the resolver will 691338032Speter examine during queue runs and daemon mode. Problem noted 691438032Speter by Dan Bernstein of the University of Illinois at Chicago. 691538032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 691638032Speter message could overflow a buffer if it was converted back 691738032Speter to 8 bits. This caused core dumps and has the potential 691838032Speter for a remote attack. Problem first noted by Gregory Shapiro 691938032Speter of WPI. 692038032Speter Avoid duplicate deliveries of error messages on systems that don't 692138032Speter have flock(2) support. Patch from Motonori Nakamura of 692238032Speter Kyoto University. 692338032Speter Ignore null FallBackMX (V) options. If this option is null (as 692438032Speter opposed to undefined) it can cause "null signature" syserrs 692538032Speter on illegal host names. 692638032Speter If a Base64 encoded text/plain message has no trailing newline in 692738032Speter the encoded text, conversion back to 8 bits will drop the 692838032Speter final line. Problem noted by Pierre David. 692938032Speter If running with a RunAsUser, sendmail would give bogus "cannot 693038032Speter setuid" (or seteuid, or setreuid) messages on some systems. 693138032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 693238032Speter Always print error messages in -bv mode -- previously, -bv would 693338032Speter be absolutely silent on errors if the error mode was sent 693438032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 693538032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 693638032Speter term host status. This is necessary because it is common 693738032Speter to do this when you know a host has just come back up. 693838032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 693938032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 694038032Speter University of Leicester. 694138032Speter If a service (such as NIS) is specified as the last entry in the 694238032Speter service switch, but that service is not compiled in, sendmail 694338032Speter would return a temporary failure when an entry was not found 694438032Speter in the map. This caused the message to be queued instead of 694538032Speter bouncing immediately. Problem noted by Harry Edmon of the 694638032Speter University of Washington. 694738032Speter PORTABILITY FIXES: 694838032Speter Solaris 2.3 had compilation problems in conf.c. Several 694938032Speter people pointed this out. 695038032Speter NetBSD from Charles Hannum of MIT. 695138032Speter AIX4 improvements based on info from Steve Bauer of South 695238032Speter Dakota School of Mines & Technology. 695338032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 695438032Speter Patch from Gil Kloepfer Jr. 695538032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 695638032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 695738032Speter were also in $=w. Problem noted by Zoltan Basti of 695838032Speter Softec. 695938032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 696038032Speter on a patch from Eric Hagberg of Morgan Stanley. 696138032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 696238032Speter of Stanford via Robert La Ferla. 696338032Speter 696464562Sgshapiro8.8.0/8.8.0 1996/09/26 696538032Speter Under some circumstances, Bcc: headers would not be properly 696638032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 696738032Speter Log a warning if the sendmail daemon is invoked without a full 696838032Speter pathname, which prevents "kill -1" from working. I was 696938032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 697038032Speter Fix small buffer overflow. Since the data in this buffer was not 697138032Speter read externally, there was no security problem (and in fact 697238032Speter probably wouldn't really overflow on most compilers). Pointed 697338032Speter out by KIZU takashi of Osaka University. 697438032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 697538032Speter if a FallbackMXHost was specified in the configuration file 697638032Speter -- all mail would be sent to the fallback even if the original 697738032Speter host was accessible. Pointed out by Munenari Hirayama of 697838032Speter NSC (Japan). 697938032Speter A message that didn't terminate with a newline would (sometimes) not 698038032Speter have the trailing "." added properly in the SMTP dialogue, 698138032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 698238032Speter The DaemonPortOptions suboption to bind to a particular address was 698338032Speter incorrect and nonfunctional due to a misunderstanding of the 698438032Speter semantics of binding on a passive socket. Patch from 698538032Speter NIIBE Yutaka of Mitsubishi Research Institute. 698638032Speter Increase the number of MX hosts for a single name to 100 to better 698738032Speter handle the truly huge service providers such as AOL, which 698838032Speter has 13 at the moment (and climbing). In order to avoid 698938032Speter trashing memory, the buffer for all names has only been 699038032Speter slightly increased in size, to 12.8K from 10.2K -- this means 699138032Speter that if a single name had 100 MX records, the average size 699238032Speter of those records could not exceed 128 bytes. Requested by 699338032Speter Brad Knowles of America On Line. 699438032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 699538032Speter Urged by Dan Bernstein of U.C. Berkeley. 699638032Speter Print q_statdate and q_specificity in address structure debugging 699738032Speter printout. 699838032Speter Expand MCI structure flag bits for debugging output. 699938032Speter Support IPv6-style domain literals, which can have colons between 700038032Speter square braces. 700138032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 700238032Speter this is an attempt to track down a bug that one person seems 700338032Speter to be having (it may be a Solaris bug!). 700438032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 700538032Speter this caused the NOTIFY info to sometimes be lost. Problem 700638032Speter pointed out by Claus Assmann of the 700738032Speter Christian-Albrechts-University of Kiel. 700838032Speter The statistics gathered in the sendmail.st file were too high; in 700938032Speter some cases failures (e.g., user unknown or temporary failure) 701038032Speter would count as a delivery as far as the statistics were 701138032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 701238032Speter Systems that don't have flock() would not send split envelopes in 701338032Speter the initial run. Problem pointed out by Leonard Zubkoff of 701438032Speter Dandelion Digital. 701538032Speter Move buffer overflow checking -- these primarily involve distrusting 701638032Speter results that may come from NIS and DNS. 701738032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 701838032Speter include <paths.h> and hence had the wrong pathnames for a few 701938032Speter things like /var/tmp. Reported by Matthew Green. 702038032Speter Conditions were reversed for the Priority: header, resulting in all 702138032Speter values being interpreted as non-urgent except for non-urgent, 702238032Speter which was interpreted as normal. Patch from Bryan Costales. 702338032Speter The -o (optional) flag was being ignored on hash and btree maps 702438032Speter since 8.7.2. Fix from Bryan Costales. 702538032Speter Content-Types listed in class "q" will always be encoded as 702638032Speter Quoted-Printable (or more accurately, will never be encoded 702738032Speter as base64). The class can have primary types (e.g., "text") 702838032Speter or full types (e.g., "text/plain"). Based on a suggestion by 702938032Speter Marius Olafsson of the University of Iceland. 703038032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 703138032Speter dialogue) so it can be passed to programs in mailers. 703238032Speter Define ${bodytype} to be the body type (from the -B flag or the 703338032Speter BODY= ESMTP parameter) so it can be passed to programs in 703438032Speter mailers. 703538032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 703638032Speter flag is set in the mailer descriptor. Suggested by John 703738032Speter Myers of CMU. 703838032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 703938032Speter The command takes a host name; data for that host is 704038032Speter immediately (and asynchronously) flushed. Because this shares 704138032Speter the -qR implementation, other hosts may be attempted, but 704238032Speter there should be no security implications. Implementation 704338032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 704438032Speter Add three new command line flags to pass in DSN parameters: -V envid 704538032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 704638032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 704738032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 704838032Speter that the -N flag applies to all recipients; there is no way 704938032Speter to specify per-address notifications on the command line, 705038032Speter nor is there an equivalent for the ORCPT= per-address 705138032Speter parameter. 705238032Speter Restore LogLevel option to be safe (it can only be increased); 705338032Speter apparently I went into paranoid mode between 8.6 and 8.7 705438032Speter and made it unsafe. Pointed out by Dabe Murphy of the 705538032Speter University of Maryland. 705638032Speter New logging on log level 15: all SMTP traffic. Patches from 705738032Speter Andrew Gross of San Diego Supercomputer Center. 705838032Speter NetInfo property value searching code wasn't stopping when it found 705938032Speter a match. This was causing the wrong values to be found (and 706038032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 706138032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 706238032Speter out by Bill Wisner of Electronics for Imaging that you can't 706338032Speter use the bracket address form for the MAIL_HUB macro, since 706438032Speter that causes the brackets to remain in the envelope recipient 706538032Speter address used for delivery. The simple fix (stripping off the 706638032Speter brackets in the config file) breaks the use of IP literal 706738032Speter addresses. This flag will solve that problem. 706838032Speter Add MustQuoteChars option. This is a list of characters that must 706938032Speter be quoted if they are found in the phrase part of an address 707038032Speter (that is, the full name part). The characters @,;:\()[] are 707138032Speter always in this list and cannot be removed. The default is 707238032Speter this list plus . and ' to match RFC 822. 707338032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 707438032Speter that do not include a host name for back compatibility with 707538032Speter some stupid SMTP clients. Setting this violates RFC 1123 707638032Speter section 5.2.5. 707738032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 707838032Speter rejecting connections if it has more than this many 707938032Speter outstanding children accepting mail. Note that you may 708038032Speter see more processes than this because of outgoing mail; this 708138032Speter is for incoming connections only. 708238032Speter Add ConnectionRateThrottle option. If set to a positive value, the 708338032Speter number of incoming SMTP connections that will be permitted 708438032Speter in a single second is limited to this number. Connections are 708538032Speter not refused during this time, just deferred. The intent is to 708638032Speter flatten out demand so that load average limiting can kick in. 708738032Speter It is less radical than MaxDaemonChildren, which will stop 708838032Speter accepting connections even if all the connections are idle 708938032Speter (e.g., due to connection caching). 709038032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 709138032Speter specifies how long cached information about the state of a 709238032Speter host will be kept before they are considered stale and the 709338032Speter host is retried. If you are using persistent host status 709438032Speter (i.e., the HostStatusDirectory option is set) this will apply 709538032Speter between runs; otherwise, it applies only within a single queue 709638032Speter run and hence is useful only for hosts that have large queues 709738032Speter that take a very long time to run. 709838032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 709938032Speter into being a single line even if they had newlines in them 710038032Speter when read. This is to get around a botch in Lotus Notes. 710138032Speter Text class maps were totally broken -- if you ever retrieved the last 710238032Speter item in a table it would be truncated. Problem noted by 710338032Speter Gregory Neil Shapiro of WPI. 710438032Speter Extend the lines printed by the mailq command (== the -bp flag) when 710538032Speter -v is given to 120 characters; this allows more information 710638032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 710738032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 710838032Speter this was treated as end-of-input. Problem noted by Bryan 710938032Speter Costales. 711038032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 711138032Speter to the queue file. Fix from John Hughes of Atlantic 711238032Speter Technologies, Inc. 711338032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 711438032Speter if this happens in a queue run it can cause nasty delays. 711538032Speter Problem noted by Mark Horton of AT&T. 711638032Speter If userdb entries pointed to userdb entries, and there were multiple 711738032Speter values for a given key, the database cursor would get 711838032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 711938032Speter of Georgia Tech. Fixed by reading all the values and creating 712038032Speter a comma-separated list; thus, the -v output will be somewhat 712138032Speter different for this case. 712238032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 712338032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 712438032Speter of Stanford University. 712538032Speter When envelopes were split due to aliases with owner- aliases, and 712638032Speter there was some error on one of the lists, more than one of 712738032Speter the owners would get the message. Problem pointed out by 712838032Speter Roy Mongiovi of Georgia Tech. 712938032Speter Detect excessive recursion in macro expansions, e.g., $X defined 713038032Speter in terms of $Y which is defined in terms of $X. Problem 713138032Speter noted by Bryan Costales; patch from Eric Wassenaar. 713238032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 713338032Speter some cases get trashed causing bogus From_ lines. Fix from 713438032Speter Kyle Jones of UUNET. 713538032Speter When doing load average initialization, if the nlist call for avenrun 713638032Speter failed, the second and subsequent lookups wouldn't notice 713738032Speter that fact causing bogus load averages to be returned. Noted 713838032Speter by Casper Dik of Sun Holland. 713938032Speter Fix problem with incompatibility with some versions of inet_aton that 714038032Speter have changed the return value to unsigned, so a check for an 714138032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 714238032Speter This could cause mail to addresses such as [foo.com] to bounce 714338032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 714438032Speter Pasteur Institute. 714538032Speter DSNs were inconsistent if a failure occurred during the DATA phase 714638032Speter rather than the RCPT phase: the Action: would be correct, but 714738032Speter the detailed status information would be wrong. Problem noted 714838032Speter by Bob Snyder of General Electric Company. 714938032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 715038032Speter that this is the initial MUA->MTA submission. The flag current 715138032Speter does nothing, but in future releases (when MUAs start using 715238032Speter these flags) it will probably turn on things like DNS 715338032Speter canonification. 715438032Speter Default end-of-line string (E= specification on mailer [M] lines) 715538032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 715638032Speter mailers. 715738032Speter Change the internal definition for the *file* and *include* mailers 715838032Speter to have $u in the argument vectors so that they aren't 715938032Speter misinterpreted as SMTP mailers and thus use \r\n line 716038032Speter termination. This will affect anyone who has redefined 716138032Speter either of these in their configuration file. 716238032Speter Don't assume that IDENT servers close the connection after a query; 716338032Speter responses can be newline terminated. From Terry Kennedy of 716438032Speter St. Peter's College. 716538032Speter Avoid core dumps on erroneous configuration files that have 716638032Speter $#mailer with nothing following. From Bryan Costales. 716738032Speter Avoid null pointer dereference with high debug values in unlockqueue. 716838032Speter Fix from Randy Martin of Clemson University. 716938032Speter Fix possible buffer overrun when expanding very large macros. Fix 717038032Speter from Kyle Jones of UUNET. 717138032Speter After 25 EXPN or VRFY commands, start pausing for a second before 717238032Speter processing each one. This avoids a certain form of denial 717338032Speter of service attack. Potential attack pointed out by Bryan 717438032Speter Costales. 717538032Speter Allow new named (not numbered!) config file rules to do validity 717638032Speter checking on SMTP arguments: check_mail for MAIL commands and 717738032Speter check_rcpt for RCPT commands. These rulesets can do anything 717838032Speter they want; their result is ignored unless they resolve to the 717938032Speter $#error mailer, in which case the indicated message is printed 718038032Speter and the command is rejected. Similarly, the check_compat 718138032Speter ruleset is called before delivery with "from_addr $| to_addr" 718238032Speter (the $| is a meta-symbol used to separate the two addresses); 718338032Speter it can give a "this sender can't send to this recipient" 718438032Speter notification. Note that this patch allows $| to stand alone 718538032Speter in rulesets. 718638032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 718738032Speter that have the name, IP address, and port number (respectively) 718838032Speter of the SMTP client (that is, the entity at the other end of 718938032Speter the connection. These can be used in (e.g.) check_rcpt to 719038032Speter verify that someone isn't trying to relay mail through your 719138032Speter host inappropriately. Be sure to use the deferred evaluation 719238032Speter form, for example $&{client_name}, to avoid having these bound 719338032Speter when sendmail reads the configuration file. 719438032Speter Add new config file rule check_relay to check the incoming connection 719538032Speter information. Like check_compat, it is passed the host name 719638032Speter and host address separated by $| and can reject connections 719738032Speter on that basis. 719838032Speter Allow IDA-style recursive function calls. Code contributed by Mark 719938032Speter Lovell and Paul Vixie. 720038032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 720138032Speter a virtual UUCP address using either a domain address or the $k 720238032Speter macro. Based on code contributed by Mark Lovell and Paul 720338032Speter Vixie. 720438032Speter Add Stanford LDAP map. Requires special libraries that are not 720538032Speter included with sendmail. Contributed by Booker C. Bense 720638032Speter <bbense@networking.stanford.edu>; contact him for support. 720738032Speter See also the src/READ_ME file. 720838032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 720938032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 721038032Speter only for debugging deep bits of code where it is important to 721138032Speter distinguish between the single-character metasymbol $+ and the 721238032Speter two characters $, +. 721338032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 721438032Speter debug_dumpstate. 721538032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 721638032Speter files that are group writable are considered "unsafe" -- that 721738032Speter is, programs and files referenced from such files are not 721838032Speter valid recipients. 721938032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 722038032Speter name that was not in DNS or was a domain-literal. Problem 722138032Speter noted by Tom May. 722238032Speter Change the introduction to error messages to more clearly delineate 722338032Speter permanent from temporary failures; if both existed in a 722438032Speter single message it could be confusing. Suggested by John 722538032Speter Beck of InReference, Inc. 722638032Speter The IngoreDot (i) option didn't work for lines that were terminated 722738032Speter with CRLF. Problem noted by Ted Stockwell of Secure 722838032Speter Computing Corporation. 722938032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 723038032Speter message headers. Problem reported by Matt Dillon of Best 723138032Speter Internet Communications. 723238032Speter Check for bogus characters in the 0200-0237 range; since these are 723338032Speter used internally, very strange errors can occur if those 723438032Speter characters appear in headers. Problem noted by Anders Gertz 723538032Speter of Lysator. 723638032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 723738032Speter recipient mailer has the F=9 flag set, and only works on 723838032Speter text/plain body types. Code contributed by Marius Olafsson 723938032Speter of the University of Iceland. 724038032Speter Special case "postmaster" name so that it is always treated as lower 724138032Speter case in alias files regardless of configuration settings; 724238032Speter this prevents some potential problems where "Postmaster" or 724338032Speter "POSTMASTER" might not match "postmaster". In most cases 724438032Speter this change is a no-op. 724538032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 724638032Speter Costales. 724738032Speter The -a map flag was ignored for dequote maps. Problem noted by 724838032Speter Bryan Costales. 724938032Speter Fix core dump when a lookup of a class "prog" map returns no 725038032Speter response. Patch from Bryan Costales. 725138032Speter Log instances where sendmail is deferring or rejecting connections 725238032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 725338032Speter Include port number in process title for network daemons. Suggested 725438032Speter by Kyle Jones of UUNET. 725538032Speter Send ``double bounces'' (errors that occur when sending an error 725638032Speter message) to the address indicated in the DoubleBounceAddress 725738032Speter option (default: postmaster). Previously they were always 725838032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 725938032Speter Add new mode, -bD, that acts like -bd in all respects except that 726038032Speter it runs in foreground. This is useful for using with a 726138032Speter wrapper that "watches" system services. Suggested by Kyle 726238032Speter Jones of UUNET. 726338032Speter Fix botch in spacing around (parenthesized) comments in addresses 726438032Speter when the comment comes before the address. Patch from 726538032Speter Motonori Nakamura of Kyoto University. 726638032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 726738032Speter that are being bounced to postmaster, rather than "Returned 726838032Speter mail". This permits the person who is postmaster more 726938032Speter easily determine what messages are to their role as 727038032Speter postmaster versus bounces to mail they actually sent. Based 727138032Speter on a suggestion by Motonori Nakamura. 727238032Speter Add new value "time" for QueueSortOrder option; this causes the queue 727338032Speter to be sorted strictly by the time of submission. Note that 727443730Speter this can cause very bad behavior over slow lines (because 727538032Speter large jobs will tend to delay small jobs) and on nodes with 727638032Speter heavy traffic (because old things in the queue for hosts that 727738032Speter are down delay processing of new jobs). Also, this does not 727838032Speter guarantee that jobs will be delivered in submission order 727938032Speter unless you also set DeliveryMode=queue. In general, it should 728038032Speter probably only be used on the command line, and only in 728138032Speter conjunction with -qRhost.domain. In fact, there are very few 728238032Speter cases where it should be used at all. Based on an 728338032Speter implementation by Motonori Nakamura. 728438032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 728538032Speter the same manner as other rulesets. Previously a temporary 728638032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 728738032Speter of Stanford University. 728838032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 728938032Speter 5yz (permanent failure) code. The next MX host will still be 729038032Speter tried if the connection cannot be opened in the first place 729138032Speter or if the MAIL command returns a 4yz (temporary failure) code. 729238032Speter (It's hard to know what to do here, since neither RFC 974 nor 729338032Speter RFC 1123 specify when to proceed to the next MX host.) 729438032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 729538032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 729638032Speter This causes map lookups that get a temporary failure (e.g., 729738032Speter name server failure) to _not_ defer the delivery of the 729838032Speter message. This should only be used if your configuration file 729938032Speter is prepared to do something sensible in this case. Based on 730038032Speter an idea by Gregory Shapiro of WPI. 730138032Speter Fix problem finding network interface addresses. Patch from 730238032Speter Motonori Nakamura. 730338032Speter Don't reject qf entries that are not owned by your effective uid if 730490792Sgshapiro you are not running set-user-ID; this makes management of 730580785Sgshapiro certain kinds of firewall setups difficult. Patch 730680785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 730738032Speter Add persistent host status. This keeps the information normally 730838032Speter maintained within a single queue run in disk files that are 730938032Speter shared between sendmail instances. The HostStatusDirectory 731038032Speter is the directory in which the information is maintained. If 731138032Speter not set, persistent host status is turned off. If not a full 731238032Speter pathname, it is relative to the queue directory. A common 731338032Speter value is ".hoststat". 731438032Speter There are also two new operation modes: 731538032Speter * -bh prints the status of hosts that have had recent 731638032Speter connections. 731738032Speter * -bH purges the host statuses. No attempt is made to save 731838032Speter recent status information. 731938032Speter This feature was originally written by Paul Vixie of Vixie 732038032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 732138032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 732238032Speter with my insistence that things fit cleanly into the V8 732338032Speter framework is gratefully appreciated. 732438032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 732538032Speter operate). Avoids letting two sendmails on the local machine 732664562Sgshapiro open connections to the same remote host at the same time. 732738032Speter This reduces load on the other machine, but can cause mail to 732838032Speter be delayed (for example, if one sendmail is delivering a huge 732938032Speter message, other sendmails won't be able to send even small 733038032Speter messages). Also, it requires another file descriptor (for the 733138032Speter lock file) per connection, so you may have to reduce 733238032Speter ConnectionCacheSize to avoid running out of per-process 733338032Speter file descriptors. Based on the persistent host status code 733438032Speter contributed by Paul Vixie and Mark Lovell. 733538032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 733638032Speter SafeFileEnvironment option is set. Problem noted by Bryan 733738032Speter Costales. 733838032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 733938032Speter file. Problem noted by Bryan Costales. 734038032Speter If a job was aborted using the interrupt signal (e.g., control-C from 734138032Speter the keyboard), on some occasions an empty df file would be 734238032Speter left around; these would collect in the queue directory. 734338032Speter Problem noted by Bryan Costales. 734438032Speter Change the makesendmail script to enhance the search for Makefiles 734538032Speter based on release number. For example, on SunOS 5.5.1, it will 734638032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 734738032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 734838032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 734938032Speter Webmasters. 735038032Speter When creating maps using "newaliases", always map the keys to lower 735138032Speter case when creating the map unless the -f flag is specified on 735238032Speter the map itself. Previously this was done based on the F=u 735338032Speter flag in the local mailer, which meant you could create aliases 735438032Speter that you could never access. Problem noted by Bob Wu of DEC. 735538032Speter When a job was read from the queue, the bits causing notification on 735638032Speter failure or delay were always set. This caused those 735738032Speter notifications to be sent even if NOTIFY=NEVER had been 735838032Speter specified. Problem noted by Steve Hubert of the University 735938032Speter of Washington, Seattle. 736038032Speter Add new configurable routine validate_connection (in conf.c). This 736138032Speter lets you decide if you are willing to accept traffic from 736238032Speter this host. If it returns FALSE, all SMTP commands will return 736338032Speter "550 Access denied". -DTCPWRAPPERS will include support for 736438032Speter TCP wrappers; you will need to add -lwrap to the link line. 736538032Speter (See src/READ_ME for details.) 736638032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 736738032Speter bounces. Some people seemed to think that this could be 736838032Speter confusing (even though it is true). Suggested by Motonori 736938032Speter Nakamura. 737038032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 737138032Speter user early in processing to avoid potential security problems. 737238032Speter However, this means that all .forward and :include: files must 737338032Speter be readable by that user, and all files to be written must be 737438032Speter writable by that user and all programs will be executed by that 737538032Speter user. It is also incompatible with the SafeFileEnvironment 737638032Speter option. In other words, it may not actually add much to 737738032Speter security. However, it should be useful on firewalls and other 737838032Speter places where users don't have accounts and the aliases file is 737938032Speter well constrained. 738038032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 738138032Speter only on the first attempt to delivery to an address. It could 738238032Speter be set to be lower than Timeout.connect on the principle that 738338032Speter the mail should go through quickly to responsive hosts; less 738438032Speter responsive hosts get to wait for the next queue run. 738538032Speter Fix a problem on Solaris that occasionally causes programs 738638032Speter (such as vacation) to hang with their standard input connected 738738032Speter to a UDP port. It also created some signal handling problems. 738838032Speter The problems turned out to be an interaction between vfork(2) 738938032Speter and some of the libraries, particularly NIS/NIS+. I am 739038032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 739138032Speter Change user class map to do the same matching that actual delivery 739238032Speter will do instead of just a /etc/passwd lookup. This adds 739338032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 739438032Speter The Timeout.* options are not safe -- they can be used to create a 739538032Speter denial-of-service attack. Problem noted by Christophe 739638032Speter Wolfhugel. 739743730Speter Don't send PostmasterCopy messages in the event of a "delayed" 739838032Speter notification. Suggested by Barry Bouwsma. 739938032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 740038032Speter option is set, since this disables VERB mode. Suggested 740138032Speter by John Hawkinson of MIT. 740238032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 740338032Speter by Motonori Nakamura of Kyoto University. 740438032Speter Only queue messages on transient .forward open failures if there 740543730Speter were no successful opens. The previous behavior caused it 740638032Speter to queue even if a "fall back" .forward was found. Problem 740738032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 740838032Speter and Computer Science (DISCS), NUS, Singapore. 740938032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 741038032Speter is bouncing because of a MIME error during 8->7 bit conversion; 741138032Speter the encapsulated message will bounce again, causing a loop. 741238032Speter Problem noted by Steve Hubert of the University of Washington. 741338032Speter Create xf (transcript) files using the TempFileMode option value 741438032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 741538032Speter National University of Singapore. 741638032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 741738032Speter detect cases where DefaultUid is set to something that the 741838032Speter system can't cope with. 741938032Speter PORTABILITY FIXES: 742038032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 742138032Speter Atlas International. 742238032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 742338032Speter <bicknell@ufp.org>. 742438032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 742538032Speter work on the first recipient of a message due to a 742638032Speter bug in the getpwent family.

Based on a patch from Randall 746938032Speter Winchester of the University of Maryland. 747038032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 747138032Speter Robert La Ferla of Hot Software. 747238032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 747338032Speter (where "code" is an exit status) on domains (previously 747438032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 747538032Speter Foundation. 747638032Speter CONFIG: hooks for IPv6-style domain literals. 747738032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 747838032Speter if it is undefined the AliasFile option is never set; this 747938032Speter should be transparent for most everyone. Suggested by John 748038032Speter Myers of CMU. 748138032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 748238032Speter domain listed in $=w is masqueraded. With it, only those 748338032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 748438032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 748538032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 748638032Speter hosts under those domains as well as the domain headers 748738032Speter themselves. For example, if a configuration had 748838032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 748938032Speter foo.com would be masqueraded; with it, *.foo.com would be 749038032Speter masqueraded as well. Based on an implementation by Richard 749138032Speter (Pug) Bainter of U. Texas. 749238032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 749338032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 749438032Speter Keys are user names; values are outgoing mail addresses. Yes, 749538032Speter this does overlap with the user database, and figuring out 749638032Speter just when to use which one may be tricky. Based on code 749738032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 749838032Speter from Per Hedeland of Ericsson. 749938032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 750038032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 750138032Speter Keys are either fully qualified addresses or just the host 750238032Speter part (with the @ sign). For example, a table containing: 750338032Speter info@foo.com foo-info 750438032Speter info@bar.com bar-info 750538032Speter @baz.org jane@elsewhere.net 750638032Speter would send all mail destined for info@foo.com to foo-info 750738032Speter (which is presumably an alias), mail addressed to info@bar.com 750838032Speter to bar-info, and anything addressed to anyone at baz.org will 750938032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 751038032Speter and baz.org must all be in $=w. Based on discussions with 751138032Speter a great many people. 751238032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 751338032Speter Suggested by Richard Bainter. 751438032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 751538032Speter "fax" mailer. 751638032Speter CONFIG: allow mailertable entries to resolve to local:user; this 751738032Speter passes the original user@host in to procmail-style local 751838032Speter mailers as the "detail" information to allow them to do 751938032Speter additional clever processing. From Joe Pruett of 752038032Speter Teleport Corporation. Delivery to the original user can 752138032Speter be done by specifying "local:" (with nothing after the colon). 752238032Speter CONFIG: allow any context that takes "mailer:domain" to also take 752338032Speter "mailer:user@domain" to force mailing to the given user; 752438032Speter "local:user" can also be used to do local delivery. This 752538032Speter applies on *_RELAY and in the mailertable entries. Based 752638032Speter on a suggestion by Ribert Kiessling of Easynet. 752738032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 752838032Speter limits the possible domains; this reduces the number of DNS 752938032Speter lookups required to support this feature. For example, 753038032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 753138032Speter to domains under my.site.com. Code contributed by Anthony 753238032Speter Thyssen <anthony@cit.gu.edu.au>. 753338032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 753438032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 753538032Speter of WPI. 753638032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 753738032Speter event you have to define local mailers. Suggested by 753838032Speter Gregory Shapiro of WPI. 753938032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 754038032Speter be misinterpreted as a list:...; syntax. Based on a patch by 754138032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 754238032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 754338032Speter remotely connected. The address host!user was being 754438032Speter converted to host!user@thishost instead of host!user@uurelay. 754538032Speter Problem noted by William Gianopoulos of Raytheon Company. 754638032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 754738032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 754838032Speter "User has moved"; the former wording was confusing if the 754938032Speter new address is still on the local host. Based on a suggestion 755038032Speter by Andreas Luik. 755138032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 755238032Speter However, the class is not pre-initialized to contain root. 755338032Speter Suggested by Gregory Neil Shapiro. 755438032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 755538032Speter Wolfhugel. 755638032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 755738032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 755838032Speter well: this produces a slightly different mailbox format (no 755938032Speter Content-Length: headers), file ownerships and modes are 756038032Speter different (not owned by group mail; mode 600 instead of 660), 756138032Speter and the local mailer flags will have to be tweaked (make them 756238032Speter match bsd4.4) in order to use this mailer. Patches from Paul 756338032Speter Hammann of the Missouri Research and Education Network. 756438032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 756538032Speter was a delivery error, such as if the ownership on the file 756638032Speter was wrong or the mode changed between the initial stat and 756738032Speter the open. Problem reported by William Colburn of the New 756838032Speter Mexico Institute of Mining and Technology. 756938032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 757038032Speter Costales. 757138032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 757238032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 757338032Speter honored. Fix from Michael Scott Shappe. 757438032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 757538032Speter NEW FILES: 757638032Speter src/Makefiles/Makefile.AIX.2 757738032Speter src/Makefiles/Makefile.IRIX.6.2 757838032Speter src/Makefiles/Makefile.maxion 757938032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 758038032Speter src/Makefiles/Makefile.SCO.5.x 758138032Speter src/Makefiles/Makefile.UXPDSV20 758238032Speter mailstats/mailstats.8 758338032Speter praliases/praliases.8 758438032Speter cf/cf/generic-nextstep3.3.mc 758538032Speter cf/feature/genericstable.m4 758638032Speter cf/feature/limited_masquerade.m4 758738032Speter cf/feature/masquerade_entire_domain.m4 758838032Speter cf/feature/virtusertable.m4 758938032Speter cf/ostype/aix2.m4 759038032Speter cf/ostype/altos.m4 759138032Speter cf/ostype/maxion.m4 759238032Speter cf/ostype/solaris2.ml.m4 759338032Speter cf/ostype/uxpds.m4 759438032Speter contrib/re-mqueue.pl 759538032Speter DELETED FILES: 759638032Speter src/Makefiles/Makefile.Solaris 759738032Speter contrib/xla/README 759838032Speter contrib/xla/xla.c 759938032Speter RENAMED FILES: 760038032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 760138032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 760238032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 760338032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 760438032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 760538032Speter 760664562Sgshapiro8.7.6/8.7.3 1996/09/17 760738032Speter SECURITY: It is possible to force getpwuid to fail when writing the 760838032Speter queue file, causing sendmail to fall back to running programs 760938032Speter as the default user. This is not exploitable from off-site. 761038032Speter Workarounds include using a unique user for the DefaultUser 761138032Speter (old u & g options) and using smrsh as the local shell. 761238032Speter SECURITY: fix some buffer overruns; in at least one case this allows 761338032Speter a local user to get root. This is not known to be exploitable 761438032Speter from off-site. The workaround is to disable chfn(1) commands. 761538032Speter 761664562Sgshapiro8.7.5/8.7.3 1996/03/04 761738032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 761838032Speter in some case cause connections to hang or messages to have 761938032Speter extra spaces in odd places. Patch from Eric Wassenaar; 762038032Speter reports from Eric Hall of Chiron Corporation, Stephen 762138032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 762238032Speter and others. 762338032Speter 762464562Sgshapiro8.7.4/8.7.3 1996/02/18 762538032Speter SECURITY: In some cases it was still possible for an attacker to 762638032Speter insert newlines into a queue file, thus allowing access to 762738032Speter any user (except root). 762838032Speter CONFIG: no changes -- it is not a bug that the configuration 762938032Speter version number is unchanged. 763038032Speter 763164562Sgshapiro8.7.3/8.7.3 1995/12/03 763238032Speter Fix botch in name server timeout in RCPT code; this problem caused 763338032Speter two responses in SMTP, which breaks things horribly. Fix 763438032Speter from Gregory Neil Shapiro of WPI. 763538032Speter Verify that L= value on M lines cannot be negative, which could cause 763638032Speter negative array subscripting. Not a security problem since 763738032Speter this has to be in the config file, but it could have caused 763838032Speter core dumps. Pointed out by Bryan Costales. 763938032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 764038032Speter Costales. 764138032Speter PORTABILITY FIXES: 764238032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 764338032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 764438032Speter order. Tweak it to work properly. Based on fixes 764538032Speter from Fletcher Mattox of UTexas and Betty Lee of 764638032Speter Stanford University. 764738032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 764838032Speter Deficiency pointed out by Bryan Costales of ICSI. 764938032Speter 765064562Sgshapiro8.7.2/8.7.2 1995/11/19 765138032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 765238032Speter OperatorChars, and UnixFromLine options. They were not 765338032Speter properly repaired in 8.7.1. 765438032Speter Completely delete the Bcc: header if and only if there are other 765538032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 765638032Speter last being a historic botch, of course). If Bcc: is the 765738032Speter only recipient header in the message, its value is tossed, 765843730Speter but the header name is kept. The old behavior (always keep 765938032Speter the header name and toss the value) allowed primary recipients 766038032Speter to see that a Bcc: went to _someone_. 766138032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 766238032Speter sender to <address> using -f'' syslog messages. Suggested 766338032Speter by Kari Hurtta. 766438032Speter If a sequence or switch map lookup entry gets a tempfail but then 766538032Speter continues on to another map type, but the name is not found, 766638032Speter return a temporary failure from the sequence or switch map. 766738032Speter For example, if hosts search ``dns files'' and DNS fails 766838032Speter with a tempfail, the hosts map will go on and search files, 766938032Speter but if it fails the whole thing should be a tempfail, not 767038032Speter a permanent (host unknown) failure, even though that is the 767138032Speter failure in the hosts.files map. This error caused hard 767238032Speter bounces when it should have requeued. 767338032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 767490792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 767538032Speter working properly due to excessive paranoia. Pointed out by 767638032Speter John Hawkinson of Panix. 767738032Speter An SMTP RCPT command referencing a host that gave a nameserver 767838032Speter timeout would return a 451 command (8.6 accepted it and 767943730Speter queued it locally). Revert to the 8.6 behavior in order 768038032Speter to simplify queue management for clustered systems. Suggested 768138032Speter by Gregory Neil Shapiro of WPI. The same problem could break 768238032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 768338032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 768438032Speter Infobiogen. 768538032Speter Fix possible buffer overflow in munchstring(). This was not a security 768638032Speter problem because you couldn't specify any argument to this 768738032Speter without first giving up root privileges, but it is still a 768838032Speter good idea to avoid future problems. Problem noted by John 768938032Speter Hawkinson and Sam Hartman of MIT. 769038032Speter ``452 Out of disk space for temp file'' messages weren't being 769138032Speter printed. Fix from David Perlin of Nanosoft. 769243730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 769338032Speter is not set, since this is required to get the actual DSNs 769438032Speter created. Problem pointed out by John Gardiner Myers of CMU. 769538032Speter Log permission problems that cause .forward and :include: files to 769638032Speter be untrusted or ignored on log level 12 and higher. Suggested 769738032Speter by Randy Martin of Clemson University. 769838032Speter Allow user ids in U= clauses of M lines to have hyphens and 769938032Speter underscores. 770038032Speter Fix overcounting of recipients -- only happened when sending to an 770138032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 770238032Speter of Systems and Computer Technology Corporation. 770338032Speter If a message is sent to an address that fails, the error message that 770438032Speter is returned could show some extraneous "success" information 770538032Speter included even if the user did not request success notification, 770638032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 770738032Speter Config files that had no AliasFile definition were defaulting to 770838032Speter using /etc/aliases; this caused problems with nullclient 770938032Speter configurations. Change it back to the 8.6 semantics of 771038032Speter having no local alias file unless it is declared. Problem 771138032Speter noted by Charles Karney of Princeton University. 771238032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 771338032Speter Costales of ICSI. 771438032Speter Map lookups of class "userdb" maps were always case sensitive; they 771538032Speter should be controlled by the -f flag like other maps. Pointed 771638032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 771738032Speter Fix problem that caused some addresses to be passed through ruleset 5 771838032Speter even when they were tagged as "sticky" by prefixing the 771938032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 772038032Speter Technological University. 772138032Speter When converting a message to Quoted-Printable, prevent any lines with 772238032Speter dots alone on a line by themselves. This is because of the 772338032Speter preponderance of broken mailers that still get this wrong. 772438032Speter Code contributed by Per Hedeland of Ericsson. 772538032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 772638032Speter out by Bjart Kvarme of USIT/UiO (Norway). 772738032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 772838032Speter Requested by Allan Johannesen. 772938032Speter Delete check for text format of alias files -- it should be legal 773038032Speter to have the database format of the alias files without the 773138032Speter text version. Problem pointed out by Joe Rhett of Navigist, 773238032Speter Inc. 773338032Speter If "Ot" was specified with no value, the TZ variable was not properly 773438032Speter imported from the environment. Pointed out by Frank Crawford 773538032Speter <frank@ansto.gov.au>. 773638032Speter Some architectures core dumped on "program" maps that didn't have 773738032Speter extra arguments. Patch from Booker C. Bense of Stanford 773838032Speter University. 773938032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 774038032Speter the parent should do this. Fix from Brian Coan of the 774138032Speter Association for Progressive Communications. 774238032Speter If MinQueueAge was set and a message was considered but not run 774338032Speter during a queue run and the Timeout.queuereturn interval was 774438032Speter reached, a "timed out" error message would be returned that 774538032Speter didn't include the failed address (and claimed to be a warning 774638032Speter even though it was fatal). The fix is to not return such 774738032Speter messages until they are actually tried, i.e., in the next 774838032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 774938032Speter SINTEF RUNIT, Oslo. 775038032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 775138032Speter that have the hes_getmailhost() routine.

Bug 779838032Speter pointed out by John Hawkinson of MIT. 779938032Speter Fix strange case of an executable called by a program map that 780038032Speter returns a value but also a non-zero exit status; this 780138032Speter would give contradictory results in the higher level; in 780238032Speter particular, the default clause in the map lookup would be 780338032Speter ignored. Change to ignore the value if the program returns 780438032Speter non-zero exit status. From Tom Moore of AT&T GIS. 780538032Speter Shorten parameters passed to syslog() in some contexts to avoid a 780638032Speter bug in many vendors' implementations of that routine. Although 780738032Speter this isn't really a bug in sendmail per se, and my solution 780838032Speter has to assume that syslog() has at least a 1K buffer size 780938032Speter internally (I know some vendors have shortened this 781038032Speter dramatically -- they're on their own), sendmail is a popular 781138032Speter target. Also, limit the size of %s arguments in sprintf. 781238032Speter These both have possible security implications. Solutions 781338032Speter suggested by Casper Dik of Sun's Network Security Group 781438032Speter (Holland), Mark Seiden, and others. 781538032Speter Fix a problem that might cause a non-standard -B (body type) 781638032Speter parameter to be passed to the next server with undefined 781738032Speter results. This could have security implications. 781838032Speter If a filesystem was at > 100% utilization, the freediskspace() 781938032Speter routine incorrectly returned an error rather than zero. 782038032Speter Problem noted by G. Paul Ziemba of Alantec. 782138032Speter Change MX sort order so that local hostnames (those in $=w) always 782238032Speter sort first within a given preference. This forces the bestmx 782338032Speter map to always return the local host first, if it is included 782438032Speter in the list of highest priority MX records. From K. Robert 782538032Speter Elz. 782638032Speter Avoid some possible null pointer dereferences. Fixes from Randy 782738032Speter Martin <WOLF@CLEMSON.EDU> 782838032Speter When sendmail starts up on systems that have no fully qualified 782938032Speter domain name (FQDN) anywhere in the first matching host map 783038032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 783138032Speter sendmail would sleep to try to find a FQDN, which it really 783238032Speter really needs. This has been changed to fall through to the 783338032Speter next map type if it can't find a FQDN -- i.e., if the hosts 783438032Speter file doesn't have a FQDN, it will try dns even though the 783538032Speter short name was found in /etc/hosts. This is probably a crock, 783638032Speter but many people have hosts files without FQDNs. Remember: 783738032Speter domain names are your friends. 783838032Speter Log a high-priority message if you can't find your FQDN during startup. 783938032Speter Suggested by Simon Barnes of Schlumberger Limited. 784038032Speter When using Hesiod, initialize it early to improve error reporting. 784138032Speter Patch from Don Lewis of Silicon Systems, Inc. 784238032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 784338032Speter connection timeout in the kernel. Add a new "connect" timeout 784438032Speter to limit this time. Defaults to zero (use whatever the 784538032Speter kernel provides). Based on code contributed by J.R. Oldroyd 784638032Speter of TerraNet. 784738032Speter Under some circumstances, a failed message would not be properly 784838032Speter removed from the queue, causing tons of bogus error messages. 784938032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 785038032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 785138032Speter of WPI. 785238032Speter PORTABILITY FIXES: 785338032Speter On IRIX 5.x, there was an inconsistency in the setting 785438032Speter of sendmail.st location. Change the Makefile to 785538032Speter install it in /var/sendmail.st to match the OSTYPE 785638032Speter file and SGI standards.

Suggested by Per Hedeland of Ericsson. 787038032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 787138032Speter otherwise the F=S causes the From_ line to imply that root is 787238032Speter the sender. Problem pointed out by Claude Scarpelli of 787338032Speter Infobiogen (France). 787438032Speter NEW FILES: 787538032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 787638032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 787738032Speter src/Makefiles/Makefile.UXPDS 787838032Speter 787964562Sgshapiro8.7/8.7 1995/09/16 788038032Speter Fix a problem that could cause sendmail to run out of file 788138032Speter descriptors due to a trashed data structure after a 788238032Speter vfork.

This was used "safely" in the sense 788838032Speter that it only did a stat, but it would have set the 788938032Speter map modification time improperly. Problem pointed out 789038032Speter by Roy Mongiovi of Georgia Tech. 789138032Speter Clean up the Subject: line on warning messages and return 789238032Speter receipts so that they don't say "Returned mail:"; this 789338032Speter can be confusing. 789438032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 789538032Speter useful enough to make it worthwhile printing on "-d". 789638032Speter Avoid logging alias statistics every time you read the alias 789738032Speter file on systems with no database method compiled in. 789838032Speter If you have a name with a trailing dot, and you try looking it 789938032Speter up using gethostbyname without the dot (for /etc/hosts 790038032Speter compatibility), be sure to turn off RES_DEFNAMES and 790138032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 790238032Speter Problem noted by Charles Amos of the University of 790338032Speter Maryland. 790438032Speter Don't do timeouts in collect if you are not running SMTP. 790538032Speter There is nothing that says you can't have a long 790638032Speter running program piped into sendmail (possibly via 790738032Speter /bin/mail, which just execs sendmail). Problem reported 790838032Speter by Don "Truck" Lewis of Silicon Systems. 790938032Speter Try gethostbyname() even if the DNS lookup fails iff option I 791038032Speter is not set. This allows you to have hosts listed in 791138032Speter NIS or /etc/hosts that are not known to DNS. It's normally 791238032Speter a bad idea, but can be useful on firewall machines. This 791338032Speter should really be broken out on a separate flag, I suppose. 791438032Speter Avoid compile warnings against BIND 4.9.3, which uses function 791538032Speter prototypes.

From Kyle Jones of UUNET. 792038032Speter SECURITY: avoid denial-of-service attacks possible by destroying 792138032Speter the alias database file by setting resource limits low. 792238032Speter This involves adding two new compile-time options: 792338032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 792438032Speter available) and HASULIMIT (indicating that ulimit(2) support 792538032Speter is available -- the Release 3 form is used). The former 792638032Speter is assumed on BSD-based systems, the latter on System 792738032Speter V-based systems. Attack noted by Phil Brandenberger of 792838032Speter Swarthmore University. 792938032Speter New syntaxes in test (-bt) mode: 793038032Speter ``.Dmvalue'' will define macro "m" to "value". 793138032Speter ``.Ccvalue'' will add "value" to class "c". 793238032Speter ``=Sruleset'' will dump the contents of the indicated 793338032Speter ruleset. 793438032Speter ``=M'' will display the known mailers. 793538032Speter ``-ddebug-spec'' is equivalent to the command-line 793638032Speter -d debug flag. 793738032Speter ``$m'' will print the value of macro $m. 793838032Speter ``$=c'' will print the contents of class $=c. 793938032Speter ``/mx host'' returns the MX records for ``host''. 794038032Speter ``/parse address'' will parse address, returning the value of 794138032Speter crackaddr (essentially, the comment information) 794238032Speter and the parsed address. 794338032Speter ``/try mailer address'' will rewrite address into the form 794438032Speter it will have when presented to the indicated mailer. 794538032Speter ``/tryflags flags'' will set flags used by parsing. The 794638032Speter flags can be `H' for header or `E' for envelope, 794738032Speter and `S' for sender or `R' for recipient. These 794838032Speter can be combined, so `HR' sets flags for header 794938032Speter recipients. 795038032Speter ``/canon hostname'' will try to canonify hostname and 795138032Speter return the result. 795238032Speter ``/map mapname key'' will look up `key' in the indicated 795338032Speter `mapname' and return the result. 795438032Speter Somewhat better handling of UNIX-domain socket addresses -- it 795538032Speter should show the pathname rather than hex bytes. 795638032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 795738032Speter the header for envelope sender information and uses 795838032Speter CR-LF as message terminators. It was thought to be 795938032Speter obsolete (used only for Arpanet NCP protocols), but it 796038032Speter turns out that the UK ``Grey Book'' protocols require 796138032Speter that functionality. 796238032Speter Fix a fix in previous release -- if gethostname and gethostbyname 796338032Speter return a name without dots, and if an attempt to canonify 796438032Speter that name fails, wait one minute and try again. This can 796538032Speter result in an extra 60 second delay on startup if your system 796638032Speter hostname (as returned by hostname(1)) has no dot and no names 796738032Speter listed in /etc/hosts or your NIS map have a dot. 796838032Speter Check for proper domain name on HELO and EHLO commands per 796938032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 797038032Speter of Michigan Technological University. 797138032Speter Relax chownsafe rules slightly -- old version said that if you 797238032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 797338032Speter if fpathconf returned EINVAL or ENOSYS), assume that 797438032Speter chown is not safe. The new version falls back to whether 797538032Speter you are on a BSD system or not. This is important for 797638032Speter SunOS, which apparently always returns one of those 797738032Speter error codes. This impacts whether you can mail to files 797838032Speter or not. 797938032Speter Syntax errors such as unbalanced parentheses in the configuration 798038032Speter file could be omitted if you had "Oem" prior to the 798138032Speter syntax error in the config file. Change to always print 798238032Speter the error message. It was especially weird because it 798338032Speter would cause a "warning" message to be sent to the Postmaster 798438032Speter for every message sent (but with no transcript). Problem 798538032Speter noted by Gregory Paris of Motorola. 798638032Speter Rewrite collect and putbody to handle full 8-bit data, including 798738032Speter zero bytes.

This is to handle the 805638032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 805738032Speter assume that ``group name:'' is a comment on the first 805838032Speter address and the ``;'' is a comment on the last address). 805938032Speter This requires config file support to get right. It does 806038032Speter understand that :: is NOT this syntax, and can be turned 806138032Speter off completely by setting the ColonOkInAddresses option. 806238032Speter Level 6 config files added with new mailer flags: 806338032Speter A Addresses are aliasable. 806438032Speter i Do udb rewriting on envelope as well as header 806538032Speter sender lines. Applies to the from address mailer 806638032Speter flags rather than the recipient mailer flags. 806738032Speter j Do udb rewriting on header recipient addresses. 806838032Speter Applies to the sender mailer flags rather than the 806938032Speter recipient mailer flags. 807038032Speter k Disable check for loops when doing HELO command. 807138032Speter o Always run as the mail recipient, even on local 807238032Speter delivery. 807338032Speter w Check for an /etc/passwd entry for this user. 807438032Speter 5 Pass addresses through ruleset 5. 807538032Speter : Check for :include: on this address. 807638032Speter | Check for |program on this address. 807738032Speter / Check for /file on this address. 807838032Speter @ Look up sender header addresses in the user 807938032Speter database. Applies to the mailer flags for the 808038032Speter mailer corresponding to the envelope sender 808138032Speter address, rather than to recipient mailer flags. 808238032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 808338032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 808438032Speter mailers, and the ColonOkInAddresses option. 808538032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 808638032Speter John Beck of Hewlett-Packard, who generously contributed 808738032Speter their implementation to me, which I then didn't use (see 808838032Speter mime.c for an explanation of why). This adds the 808938032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 809038032Speter to control handling of 8-bit data. These have to cope with 809138032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 809238032Speter 8-bit data that is entered without declaring it as 8-bit 809338032Speter MIME -- technically this is illegal according to the 809438032Speter specs) and labelled 8-bit data (that is, it was declared 809538032Speter as 8BITMIME in the ESMTP session or by using the 809638032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 809738032Speter set then 8-bit data is sent to non-8BITMIME machines 809838032Speter instead of converting to 7 bit (essentially using 809938032Speter just-send-8 semantics). The values for EightBitMode are: 810038032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 810138032Speter any necessary conversion of 8BITMIME to 7BIT 810238032Speter (essentially, the full MIME option). 810338032Speter p pass unlabelled 8-bit input, but convert labelled 810438032Speter 8BITMIME input to 7BIT as required (default). 810538032Speter s strict adherence: reject unlabelled 8-bit input, 810638032Speter convert 8BITMIME to 7BIT as required. The F=8 810738032Speter flag is ignored. 810838032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 810938032Speter the setting of F=8. 811038032Speter Add new internal class 'n', which is the set of MIME Content-Types 811138032Speter which can not be 8 to 7 bit encoded because of other 811238032Speter considerations. Types "multipart/*" and "message/*" are 811338032Speter never directly encoded (although their components can be). 811438032Speter Add new internal class 's', which is the set of subtypes of the 811538032Speter MIME message/* content type that can be treated as though 811638032Speter they are an RFC822 message. It is predefined to have 811738032Speter "rfc822". Suggested By Kari Hurtta. 811838032Speter Add new internal class 'e'. This is the set of MIME 811938032Speter Content-Transfer-Encodings that can be converted to 812038032Speter a seven bit format (Quoted-Printable or Base64). It is 812138032Speter preinitialized to contain "7bit", "8bit", and "binary". 812238032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 812338032Speter short name) to set the default character set to use in the 812438032Speter Content-Type: header when doing encoding of an 8-bit message 812538032Speter which isn't marked as MIME into MIME format. If the C= 812638032Speter parameter is set on the Envelope From address, use that as 812738032Speter the default encoding; else use the DefaultCharSet option. 812838032Speter If neither is set, it defaults to "unknown-8bit" as 812938032Speter suggested by RFC 1428 section 3. 813038032Speter Allow ``U=user:group'' field in mailer definition to set a default 813138032Speter user and group that a mailer will be executed as. This 813238032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 813338032Speter also set, it is the uid/gid that will always be used (that 813438032Speter is, the controlling address is ignored). The values may be 813538032Speter numeric or symbolic; if only a symbolic user is given (no 813638032Speter group) that user's default group in the passwd file is used 813738032Speter as the group. Based on code donated by Chip Rosenthal of 813838032Speter Unicom. 813938032Speter Allow `u' option to also accept user:group as a value, in the same 814038032Speter fashion as the U= mailer option. 814138032Speter Add the symbolic time zone name in the Arpanet format dates (as 814238032Speter a comment). This adds a new compile-time configuration 814338032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 814438032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 814538032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 814638032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 814738032Speter timezone()), or TZ_NONE (don't include the comment). Code 814838032Speter from Chip Rosenthal. 814938032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 815038032Speter For example, 815138032Speter O Timeout.helo = 2m 815238032Speter There are also two new suboptions "queuereturn" and 815338032Speter "queuewarn"; these subsume the old T option. Thus, to 815438032Speter set them both the preferred new syntax is 815538032Speter O Timeout.queuereturn = 5d 815638032Speter O Timeout.queuewarn = 4h 815738032Speter Sort queue by host name instead of by message priority if the 815838032Speter QueueSortOrder option (no short name) is set is set to 815938032Speter ``host''. This makes better use of the connection cache, 816038032Speter but may delay more ``interactive'' messages behind large 816138032Speter backlogs under some circumstances. This is probably a 816238032Speter good option if you have high speed links or don't do lots 816338032Speter of ``batch'' messages, but less good if you are using 816438032Speter something like PPP on a 14.4 modem. Based on code 816538032Speter contributed by Roy Mongiovi of Georgia Tech (my main 816638032Speter contribution was to make it configurable). 816738032Speter Save i-number of df file in qf file to simplify rebuilding of queue 816838032Speter after disastrous disk crash. Suggested by Kyle Jones of 816938032Speter UUNET; closely based on code from KJS DECWRL code written 817038032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 817138032Speter are NOT back compatible with 8.6 -- that is, you can convert 817238032Speter from 8.6 to 8.7, but not the other direction. 817338032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 817438032Speter route-addrs in envelopes; this is because in some cases 817538032Speter they can be sent to the shell, which interprets them as 817638032Speter I/O redirection. 817738032Speter Don't include error file (option E) with return-receipts; this 817838032Speter can be confusing. 817938032Speter Don't send "Warning: cannot send" messages to owner-* or 818038032Speter *-request addresses. Suggested by Christophe Wolfhugel 818138032Speter of the Institut Pasteur, Paris. 818238032Speter Allow -O command line flag to set long form options. 818338032Speter Add "MinQueueAge" option to set the minimum time between attempts 818438032Speter to run the queue. For example, if the queue interval 818538032Speter (-q value) is five minutes, but the minimum queue age 818638032Speter is fifteen minutes, jobs won't be tried more often than 818738032Speter once every fifteen minutes. This can be used to give 818838032Speter you more responsiveness if your delivery mode is set to 818938032Speter queue-only. 819038032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 819138032Speter :include: and .forward files. 819238032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 819338032Speter key field name, the value field name, and the field 819438032Speter delimiter. The field delimiter can be a single character 819538032Speter or the sequence "\t" or "\n" for tab or newline. 819638032Speter These are for use by NIS+ and similar access methods. 819738032Speter Change maps to always strip quotes before lookups; the -q flag 819843730Speter turns off this behavior. Suggested by Motonori Nakamura. 819938032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 820038032Speter key and value field names respectively. Code donated by 820138032Speter Sun Microsystems. 820238032Speter Add "hesiod" map class. The "file name" is used as the 820338032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 820438032Speter first value found for the match. Code donated by Scott 820538032Speter Hutton of Indiana University. 820638032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 820738032Speter specify the name of the property that is searched as the 820838032Speter key and a -v flag to specify the name of the property that 820938032Speter is returned as the value (defaults to "members"). The 821038032Speter default map is "/aliases". Some code based on code 821138032Speter contributed by Robert La Ferla of Hot Software. 821238032Speter Add "text" map class. This does slow, linear searches through 821338032Speter text files. The -z flag specifies a column delimiter 821438032Speter (defaults to any sequence of white space), the -k flag 821538032Speter sets the key column number, and the -v flag sets the 821638032Speter value column number. Lines beginning with `#' are treated 821738032Speter as comments. 821838032Speter Add "program" map class to execute arbitrary programs. The search 821938032Speter key is presented as the last argument; the output is one 822038032Speter line read from the programs standard output. Exit statuses 822138032Speter are from sysexits.h. 822238032Speter Add "sequence" map class -- searches maps in sequence until it 822338032Speter finds a match. For example, the declarations: 822438032Speter Kmap1 ... 822538032Speter Kmap2 ... 822638032Speter Kmapseq sequence map1 map2 822738032Speter defines a map "mapseq" that first searches map1; if the 822838032Speter value is found it is returned immediately, otherwise 822938032Speter map2 is searched and the value returned. 823038032Speter Add "switch" map class. This is much like "sequence" except that 823138032Speter the ordering is fetched from an external file, usually 823238032Speter the system service switch. The parameter is the name of 823338032Speter the service to switch on, and the maps that it will use 823438032Speter are the name of the switch map followed by ".service_type". 823538032Speter For example, if the declaration of the map is 823638032Speter Ksample switch hosts 823738032Speter and the system service switch specifies that hosts are 823838032Speter looked up using dns and nis in that order, then this is 823938032Speter equivalent to 824038032Speter Ksample sequence sample.dns sample.nis 824138032Speter The subordinate maps (sample.*) must already be defined. 824238032Speter Add "user" map class -- looks up users using getpwnam. Takes a 824338032Speter "-v field" flag on the definition that tells what passwd 824438032Speter entry to return -- legal values are name, passwd, uid, gid, 824538032Speter gecos, dir, and shell. Generally expected to be used with 824638032Speter the -m (matchonly) flag. 824738032Speter Add "bestmx" map class -- returns the best MX value for the host 824838032Speter listed as the value. If there are several "best" MX records 824938032Speter for this host, one will be chosen at random. 825038032Speter Add "userdb" map class -- looks up entries in the user database. 825138032Speter The "file name" is actually the tag that will be used, 825238032Speter typically "mailname". If there are multiple entries 825338032Speter matching the name, the one chosen is undefined. 825438032Speter Add multiple queue timeouts (both return and warning). These are 825538032Speter set by the Precedence: or Priority: header fields to one of 825638032Speter three values. If a Priority: is set and has value "normal", 825764562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 825838032Speter used. If no priority is set, the Precedence: is consulted; 825938032Speter if negative, non-urgent timeouts are used; if greater than 826038032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 826138032Speter are used. The timeouts are set by setting the six timeouts 826238032Speter queue{warn,return}.{urgent,normal,non-urgent}. 826338032Speter Fix problem when a mail address is resolved to a $#error mailer 826438032Speter with a temporary failure indication; it works in SMTP, 826538032Speter but when delivering locally the mail is silently discarded. 826638032Speter This patch, from Kyle Jones of UUNET, bounces it instead 826738032Speter of queueing it (queueing is very hard). 826838032Speter When using /etc/hosts or NIS-style lookups, don't assume that 826938032Speter the first name in the list is the best one -- instead, 827038032Speter search for the first one with a dot. For example, if 827138032Speter an /etc/hosts entry reads 827238032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 827338032Speter this change will use the second name as the canonical 827438032Speter machine name instead of the initial, unqualified name. 827538032Speter Change dequote map to replace spaces in quoted text with a value 827638032Speter indicated by the -s flag on the dequote map definition. 827738032Speter For example, ``Mdequote dequote -s_'' will change 827838032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 827938032Speter quoted (because of the space character). Suggested by Dan 828038032Speter Oscarsson for use in X.400 addresses. 828138032Speter Implement long macro names as ${name}; long class names can 828238032Speter be similarly referenced as $={name} and $~{name}. 828338032Speter Definitions are (e.g.) ``D{name}value''. Names that have 828438032Speter a leading lower case letter or punctuation characters are 828538032Speter reserved for internal use by sendmail; i.e., config files 828638032Speter should use names that begin with a capital letter. Based 828738032Speter on code contributed by Dan Oscarsson. 828838032Speter Fix core dump if getgrgid returns a null group list (as opposed 828938032Speter to an empty group list, that is, a pointer to a list 829038032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 829138032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 829238032Speter failed, it called syserr which called newstr which called 829338032Speter xalloc.... The newstr is now avoided for "panic" messages. 829438032Speter Reported by Stuart Kemp of James Cook University. 829538032Speter Improve connection cache timeouts; previously, they were not even 829638032Speter checked if you were delivering to anything other than an 829738032Speter IPC-connected host, so a series of (say) local mail 829838032Speter deliveries could cause cached connections to be open 829938032Speter much longer than the specified timeout. 830038032Speter If an incoming message exceeds the maximum message size, stop 830138032Speter writing the incoming bytes to the queue data file, since 830238032Speter this can fill your mqueue partition -- this is a possible 830338032Speter denial-of-service attack. 830438032Speter Don't reject all numeric local user names unless HESIOD is 830538032Speter defined. It turns out that Posix allows all-numeric 830638032Speter user names. Fix from Tony Sanders of BSDI. 830738032Speter Add service switch support. If the local OS has a service 830838032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 830938032Speter on DEC systems) that will be used; otherwise, it falls back 831038032Speter to using a local mechanism based on the ServiceSwitchFile 831138032Speter option (default: /etc/service.switch). For example, if the 831238032Speter service switch lists "files" and "nis" for the aliases 831338032Speter service, that will be the default lookup order. the "files" 831438032Speter ("local" on DEC) service type expands to any alias files 831538032Speter you listed in the configuration file, even if they aren't 831638032Speter actually file lookups. 831738032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 831838032Speter variable which tells whether or not DNS should be considered 831938032Speter canonical. This is now determined based on whether or not 832038032Speter "dns" is in the service list for "hosts". 832138032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 832238032Speter Status Notifications). DSN notifications override 832338032Speter Return-Receipt-To: headers, which are bogus anyhow -- 832438032Speter support for them has been removed. 832538032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 832638032Speter definitions to define the types used in DSN returns for 832738032Speter MTA names, addresses, and diagnostics respectively. 832838032Speter Extend heuristic to force running in ESMTP mode to look for the 832938032Speter five-character string "ESMTP" anywhere in the 220 greeting 833038032Speter message (not just the second line). This is to provide 833138032Speter better compatibility with other ESMTP servers. 833238032Speter Print sequence number of job when running the queue so you can 833338032Speter easily see how much progress you have made. Suggested 833438032Speter by Peter Wemm of DIALix. 833538032Speter Map newlines to spaces in logged message-ids; some versions of 833638032Speter syslog truncate the rest of the line after newlines. 833738032Speter Suggested by Fletcher Mattox of U. Texas. 833838032Speter Move up forking for job runs so that if a message is split into 833938032Speter multiple envelopes you don't get "fork storms" -- this 834038032Speter also improves the connection cache utilization. 834138032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 834238032Speter the purposes of refusing to send error returns. Suggested 834338032Speter by Motonori Nakamura of Ritsumeikan University. 834438032Speter Relax rules on when a file can be written when referenced from 834538032Speter the aliases file: use the default uid/gid instead of the 834638032Speter real uid/gid. This allows you to create a file owned by 834738032Speter and writable only by the default uid/gid that will work 834890792Sgshapiro all the time (without having the set-user-ID bit set). Change 834938032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 835038032Speter Microsystems. 835138032Speter Add "DialDelay" option (no short name) to provide an "extra" 835238032Speter delay for dial on demand systems. If this is non-zero 835338032Speter and a connect fails, sendmail will wait this long and 835438032Speter then try again. If it takes longer than the kernel 835538032Speter timeout interval to establish the connection, this 835638032Speter option can give the network software time to establish 835738032Speter the link. The default units are seconds. 835838032Speter Move logging of sender information to be as early as possible; 835938032Speter previously, it could be delayed a while for SMTP mail 836038032Speter sent to aliases. Suggested by Brad Knowles of the 836138032Speter Defense Information Systems Agency. 836238032Speter Call res_init() before setting RES_DEBUG; this is required by 836338032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 836438032Speter the National Computer Security Center. 836538032Speter Add xdelay= field in logs -- this is a transaction delay, telling 836638032Speter you how long it took to deliver to this address on the 836738032Speter last try. It is intended to be used for sorting mailing 836838032Speter lists to favor "quick" addresses. Provided for use by 836938032Speter the mailprio scripts (see below). 837038032Speter If a map cannot be opened, and that map is non-optional, and 837138032Speter an address requires that map for resolution, queue the 837238032Speter map instead of bouncing it. This involves creating a 837338032Speter pseudo-class of maps called "bogus-map" -- if a required 837438032Speter map cannot be opened, the class is changed to bogus-map; 837538032Speter all queries against bogus-map return "tempfail". The 837638032Speter bogus-map class is not directly accessible. A sample 837738032Speter implementation was donated by Jem Taylor of Glasgow 837838032Speter University Computing Service. 837938032Speter Fix a possible core dump when mailing to a program that talks 838038032Speter SMTP on its standard input. Fix from Keith Moore of 838138032Speter the University of Kentucky. 838238032Speter Make it possible to resolve filenames to $#local $: @ /filename; 838338032Speter previously, the "@" would cause it to not be recognized 838438032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 838538032Speter Accept a -1 signal to re-exec the daemon. This only works if 838638032Speter argv[0] is a full path to sendmail. 838738032Speter Fix bug in "addr=..." field in O option on little-endian machines 838838032Speter -- the network number wasn't being converted to network 838938032Speter byte order. Patch from Kurt Lidl of Pix Technologies 839038032Speter Corporation. 839138032Speter Pre-initialize the resolver early on; this is to avoid a bug with 839238032Speter BIND 4.9.3 that can cause the _res.retry field to get 839338032Speter reset to zero, causing all name server lookups to time 839438032Speter out. Fix from Matt Day of Artisoft. 839538032Speter Restore T line (trusted users) in config file -- but instead of 839638032Speter locking out the -f flag, they just tell whether or not 839738032Speter an X-Authentication-Warning: will be added. This really 839838032Speter just creates new entries in class 't', so "Ft/file/name" 839938032Speter can be used to read trusted user names from a file. 840038032Speter Trusted users are also allowed to execute programs even 840138032Speter if they have a shell that isn't in /etc/shells. 840238032Speter Improve NEWDB alias file rebuilding so it will create them 840338032Speter properly if they do not already exist. This had been 840438032Speter a MAYBENEXTRELEASE feature in 8.6.9. 840538032Speter Check for @:@ entry in NIS maps before starting up to avoid 840638032Speter (but not prevent, sigh) race conditions. This ought to 840738032Speter be handled properly in ypserv, but isn't. Suggested by 840838032Speter Michael Beirne of Motorola. 840938032Speter Refuse connections if there isn't enough space on the filesystem 841038032Speter holding the queue. Contributed by Robert Dana of Wolf 841138032Speter Communications. 841238032Speter Skip checking for directory permissions in the path to a file 841338032Speter when checking for file permissions iff setreuid() 841438032Speter succeeded -- it is unnecessary in that case. This avoids 841538032Speter significant performance problems when looking for .forward 841638032Speter files. Based on a suggestion by Win Bent of USC. 841738032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 841838032Speter arbitrary ruleset number assigned or "Sname = integer" 841938032Speter to assign a specific ruleset number. Reference is 842038032Speter $>name_or_number. Names can be composed of alphas, digits, 842138032Speter underscore, or hyphen (first character must be non-numeric). 842238032Speter Allow -o flag on AliasFile lines to make the alias file optional. 842338032Speter From Bryan Costales of ICSI. 842438032Speter Add NoRecipientAction option to handle the case where there is 842538032Speter no legal recipient header in the message. It can take 842638032Speter on values: 842738032Speter None Leave the message as is. The 842838032Speter message will be passed on even 842938032Speter though it is in technically 843038032Speter illegal syntax. 843138032Speter Add-To Add a To: header with any 843238032Speter recipients that it can find from 843338032Speter the envelope. This risks exposing 843438032Speter Bcc: recipients. 843538032Speter Add-Apparently-To Add an Apparently-To: header. This 843638032Speter has almost no redeeming social value, 843738032Speter and is provided only for back 843838032Speter compatibility. 843938032Speter Add-To-Undisclosed Add a header reading 844038032Speter To: undisclosed-recipients:; 844138032Speter which will have the effect of 844238032Speter making the message legal without 844338032Speter exposing Bcc: recipients. 844438032Speter Add-Bcc To add an empty Bcc: header. 844538032Speter There is a chance that mailers down 844638032Speter the line will delete this header, 844738032Speter which could cause exposure of Bcc: 844838032Speter recipients. 844938032Speter The default is NoRecipientAction=None. 845038032Speter Truncate (rather than delete) Bcc: lines in the header. This 845138032Speter should prevent later sendmails (at least, those that don't 845238032Speter themselves delete Bcc:) from considering this message to 845338032Speter be non-conforming -- although it does imply that non-blind 845438032Speter recipients can see that a Bcc: was sent, albeit not to whom. 845538032Speter Add SafeFileEnvironment option. If declared, files named as delivery 845638032Speter targets must be regular files in addition to the regular 845738032Speter checks. Also, if the option is non-null then it is used as 845838032Speter the name of a directory that is used as a chroot(2) 845938032Speter environment for the delivery; the file names listed in an 846038032Speter alias or forward should include the name of this root. 846138032Speter For example, if you run with 846238032Speter O SafeFileEnvironment=/arch 846338032Speter then aliases should reference "/arch/rest/of/path". If a 846438032Speter value is given, sendmail also won't try to save to 846538032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 846638032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 846738032Speter Support -A flag for alias files; this will comma concatenate like 846838032Speter entries. For example, given the aliases: 846938032Speter list: member1 847038032Speter list: member2 847138032Speter and an alias file declared as: 847238032Speter OAhash:-A /etc/aliases 847338032Speter the final alias inserted will be "list: member1,member2"; 847438032Speter without -A you will get an error on the second and subsequent 847538032Speter alias for "list". Contributed by Bryan Costales of ICSI. 847638032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 847738032Speter Fix a problem that could cause very long addresses to core dump in 847838032Speter some special circumstances. Problem pointed out by Allan 847938032Speter Johannesen. 848038032Speter (Internal change.) Change interface to expand() (macro expansion) 848138032Speter to be simpler and more consistent. 848238032Speter Delete check for funny qf file names. This didn't really give 848338032Speter any extra security and caused some people some problems. 848438032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 848538032Speter at compile time.) Suggested by Kyle Jones of UUNET. 848638032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 848738032Speter merge with DSN code; this is simpler and more consistent. 848838032Speter This may affect some people who have written their own 848938032Speter checkcompat() routine. 849038032Speter (Internal change.) Eliminate `D' line in qf file. The df file 849138032Speter is now assumed to be the same name as the qf file (with 849238032Speter the `q' changed to a `d', of course). 849338032Speter Avoid forking for delivery if all recipient mailers are marked as 849438032Speter "expensive" -- this can be a major cost on some systems. 849538032Speter Essentially, this forces sendmail into "queue only" mode 849638032Speter if all it is going to do is queue anyway. 849738032Speter Avoid sending a null message in some rather unusual circumstances 849838032Speter (specifically, the RCPT command returns a temporary 849938032Speter failure but the connection is lost before the DATA 850038032Speter command). Fix from Scott Hammond of Secure Computing 850138032Speter Corporation. 850238032Speter Change makesendmail to use a somewhat more rational naming scheme: 850338032Speter Makefiles and obj directories are named $os.$rel.$arch, 850438032Speter where $os is the operating system (e.g., SunOS), $rel is 850538032Speter the release number (e.g., 5.3), and $arch is the machine 850638032Speter architecture (e.g., sun4). Any of these can be omitted, 850738032Speter and anything after the first dot in a release number can 850838032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 850938032Speter version used $os.$arch.$rel and was rather less general. 851038032Speter Change makesendmail to do a "make depend" in the target directory 851138032Speter when it is being created. This involves adding an empty 851238032Speter "depend:" entry in most Makefiles. 851338032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 851438032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 851538032Speter of the Finnish Meteorological Institute. 851638032Speter Fix problem that could cause multiple responses to DATA command 851738032Speter on header syntax errors (e.g., lines beginning with colons). 851838032Speter Problem noted by Jens Thomassen of the University of Oslo. 851938032Speter Don't let null bytes in headers cause truncation of the rest of 852038032Speter the header. 852138032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 852238032Speter Increase timeouts on message data puts to allow time for receivers 852338032Speter to canonify addresses in headers on the fly. This is still 852438032Speter a rather ugly heuristic. From Motonori Nakamura. 852538032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 852638032Speter records are not used when canonifying names, and when MX 852738032Speter lookups are done for addressing they must be fully 852838032Speter qualified. This is useful if you have a wildcard MX record, 852938032Speter although it may cause other problems. In general, don't use 853038032Speter wildcard MX records. Patch from Motonori Nakamura. 853138032Speter Eliminate default two-line SMTP greeting message. Instead of 853238032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 853338032Speter is added between the first and second word of the first 853438032Speter line of the greeting message (i.e., immediately after the 853538032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 853638032Speter compile flag. Old sendmails won't see the ESMTP, but that's 853738032Speter acceptable because SIZE was the only useful extension that 853838032Speter old sendmails understand. 853938032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 854038032Speter invoked state dumps. From Masaharu Onishi. 854138032Speter Allow on-line comments in .forward and :include: files; they are 854238032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 854338032Speter is a space or a tab. This is intended for native 854438032Speter representation of non-ASCII sets such as Japanese, where 854538032Speter existing encodings would be unreadable or would lose 854638032Speter data -- for example, 854738032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 854838032Speter (romanized/less information) 854938032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 855038032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 855138032Speter (with MIME encoding, not human readable) 855238032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 855338032Speter (native encoding with ISO-2022-JP) 855438032Speter The last form is human readable in the Japanese environment. 855538032Speter Based on a fix from (surprise!) Motonori Nakamura. 855638032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 855738032Speter messages to that host; these are most frequently associated 855838032Speter with addresses rather than the host, with the exception of 855938032Speter 421 (service shutting down). The effect was to cause queues 856038032Speter to sometimes take an excessive time to flush. Reported by 856138032Speter Robert Sargent of Southern Geographics Technologies and 856238032Speter Eric Prestemon of American University. 856338032Speter Add Nice=N mailer option to set the niceness at which a mailer will 856438032Speter run. This is actually a relative niceness (that is, an 856538032Speter increment on the background value). 856638032Speter Log queue runs that are skipped due to high loads. They are logged 856738032Speter at LOG_INFO priority iff the log level is > 8. Contributed 856838032Speter by Bruce Nagel of Data General. 856938032Speter Allow the error mailer to accept a DSN-style error status code 857038032Speter instead of an sysexits status code in the host part. 857138032Speter Anything with a dot will be interpreted as a DSN-style code. 857238032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 857338032Speter to encode characters that might be munged by an EBCDIC system 857438032Speter in addition to the set required by RFC 1521. The additional 857538032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 857638032Speter (Think of "IBM 360" as the mnemonic for this flag.) 857738032Speter Change check for mailing to files to look for a pathname of [FILE] 857838032Speter rather than looking for the mailer named *file*. The mapping 857938032Speter of leading slashes still goes to the *file* mailer. This 858038032Speter allows you to implement the *file* mailer as a separate 858138032Speter program, for example, to insert a Content-Length: header 858238032Speter or do special security policy. However, note that the usual 858338032Speter initial checking for the file permissions is still done, and 858438032Speter the program in question needs to be very careful about how 858538032Speter it does the file write to avoid security problems. 858638032Speter Be able to read ~root/.forward even if the path isn't accessible to 858738032Speter regular users. This is disrecommended because sendmail 858838032Speter sometimes does not run as root (e.g., when an unsafe option 858938032Speter is specified on the command line), but should otherwise be 859038032Speter safe because .forward files must be owned by the user for 859138032Speter whom mail is being forwarded, and cannot be a symbolic link. 859238032Speter Suggested by Forrest Aldrich of Wang Laboratories. 859338032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 859438032Speter file. This is used for canonifying hostnames when the 859538032Speter service type is "files". 859638032Speter Implement programs on F (read class from file) line. The syntax is 859738032Speter Fc|/path/to/program to read the output from the program 859838032Speter into class "c". 859938032Speter Probe the network interfaces to find alternate names for this 860038032Speter host. Requires the SIOCGIFCONF ioctl call. Code 860138032Speter contributed by SunSoft. 860238032Speter Add "E" configuration line to set or propagate environment 860338032Speter variables into children. "E<envar>" will propagate 860438032Speter the named variable from the environment when sendmail 860538032Speter was invoked into any children it calls; "E<envar>=<value>" 860638032Speter sets the named variable to the indicated value. Any 860738032Speter variables not explicitly named will not be in the child 860838032Speter environment. However, sendmail still forces an 860938032Speter "AGENT=sendmail" environment variable, in part to enforce 861038032Speter at least one environment variable, since many programs and 861138032Speter libraries die horribly if this is not guaranteed. 861238032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 861338032Speter alias databases -- new algorithm looks for the substring 861438032Speter "/yp/" in the file name. This is more portable and involves 861538032Speter less overhead. Suggested by Motonori Nakamura. 861638032Speter Dynamically allocate the queue work list so that you don't lose 861738032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 861838032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 861938032Speter should not need to be changed) and the MaxQueueRunSize option, 862038032Speter which is the absolute maximum number of jobs that will ever 862138032Speter be handled in a single queue run. Based on code contributed 862238032Speter by Brian Coan of the Institute for Global Communications. 862338032Speter Log message when a message is dropped because it exceeds the maximum 862438032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 862538032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 862638032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 862738032Speter of Mark G. Thomas Consulting. 862838032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 862938032Speter OS-dependent defines). The old semantic of -d0.1 to not 863038032Speter run the daemon in background has been moved to -d99.100, 863138032Speter and the old 52.5 flag (to avoid disconnect() from closing 863238032Speter all output files) has been moved to 52.100. This makes 863338032Speter things more consistent (flags below .100 don't change 863438032Speter semantics) and separates out the backgrounding so that 863538032Speter it doesn't happen automatically on other unrelated debugging 863638032Speter flags. 863738032Speter If -t is used but no addresses are found in the header, give an 863838032Speter error message rather than just doing nothing. Fix from 863938032Speter Motonori Nakamura. 864038032Speter On systems (like SunOS) where the effective gid is not necessarily 864138032Speter included in the group list returned by getgroups(), the 864238032Speter `restrictmailq' option could sometimes cause an authorized 864338032Speter user to not be able to use `mailq'. Fix from Charles Hannum 864438032Speter of MIT. 864538032Speter Allow symbolic service names for [IPC] mailers. Suggested by 864638032Speter Gerry Magennis of Logica International. 864738032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 864838032Speter when running DNS. For example, if the name FTP.Foo.ORG is 864938032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 865038032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 865138032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 865238032Speter This is technically illegal under RFC 822 and 1123, but the 865338032Speter IETF is moving toward legalizing it. Note that turning on 865438032Speter this option is not sufficient to guarantee that a downstream 865538032Speter neighbor won't rewrite the address for you. 865638032Speter Add "-m" flag to makesendmail script -- this tells you what object 865738032Speter directory and Makefile it will use, but doesn't actually do 865838032Speter the make. 865938032Speter Do some additional checking on the contents of the qf file to try 866038032Speter to detect attacks against the qf file. In particular, 866138032Speter abort on any line beginning "From ", and add an "end of 866238032Speter file" line -- any data after that line is prohibited. 866338032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 866438032Speter choices. This can be overridden in the Makefile by using 866538032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 866638032Speter (to the extent that we know it) or by defining 866738032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 866838032Speter sendmail 8 to have more consistent installation instructions. 866938032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 867038032Speter of Sun Microsystems. 867138032Speter Improved symbol table hash function from Eric Wassenaar. This one 867238032Speter is at least 50% faster. 867338032Speter Fix problem that didn't notice that timeout on file open was a 867438032Speter transient error. Fix from Larry Parmelee of Cornell 867538032Speter University. 867638032Speter Allow comments (lines beginning with a `#') in files read for 867738032Speter classes. Suggested by Motonori Nakamura. 867838032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 867938032Speter of dropping out entirely. This makes testing some of the 868038032Speter name server lookups easier to deal with when there are 868138032Speter hung servers. From Motonori Nakamura. 868238032Speter Add new ${opMode} macro that is set to the current operation mode 868338032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 868438032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 868538032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 868638032Speter Kind of like queue-only mode (Odq) except it tries to avoid 868738032Speter any external service requests; for dial-on-demand hosts that 868838032Speter want to minimize DNS lookups when mail is being queued. For 868938032Speter this to work you will also have to make sure that gethostbyname 869038032Speter of your local host name does not do a DNS lookup. 869138032Speter Improved handling of "out of space" conditions from John Myers of 869238032Speter Carnegie Mellon. 869338032Speter Improved security for mailing to files on systems that have fchmod(2) 869438032Speter support. 869538032Speter Improve "cannot send message for N days" message -- now says "could 869638032Speter not send for past N days". Suggested by Tom Moore of AT&T 869738032Speter Global Information Solutions. 869838032Speter Less misleading Subject: line on messages sent to postmaster only. 869938032Speter From Motonori Nakamura. 870038032Speter Avoid duplicate error messages on bad command line flags. From 870138032Speter Motonori Nakamura. 870238032Speter Better error message for case where ruleset 0 falls off the end 870338032Speter or otherwise does not resolve to a canonical triple. 870438032Speter Fix a problem that could cause multiple bounce messages if a bad 870538032Speter address was sent along with a good address to an SMTP 870638032Speter site where that SMTP site returned a 4yz code in response 870738032Speter to the final dot of the data. Problem reported by David 870838032Speter James of British Telecom. 870938032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 871038032Speter from Alexander Dupuy of System Management ARTS. 871138032Speter Delete duplicates in MX lists -- believe it or not, there are sites 871238032Speter that list the same host twice in an MX list. This deletion 871338032Speter only works on adjacent preferences, so an MX list that 871438032Speter had A=5, B=10, A=15 would leave both As, but one that had 871538032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 871638032Speter just in case there is something weird I haven't thought of. 871738032Speter Suggested by Barry Shein of Software Tool & Die. 871838032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 881338032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 881438032Speter University of Brno (Czech Republic). 881538032Speter KSR OS 1.2.2 support from Todd Miller of the University 881638032Speter of Colorado. 881738032Speter UX4800 support from Kazuhisa Shimizu of NEC. 881838032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 881938032Speter in type ``btree'' maps. The semantics of this are undefined 882038032Speter for regular maps, but it can be useful for the user database. 882138032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 882238032Speter lookups while the rebuild is going on. There is a race 882338032Speter condition between the open(... O_TRUNC ...) and the lock 882438032Speter on the file, but it should be quite small. 882538032Speter SMRSH: sendmail restricted shell added to the release. This can 882638032Speter be used as an alternative to /bin/sh for the "prog" mailer, 882738032Speter giving the local administrator more control over what 882838032Speter programs can be run from sendmail. 882938032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 883038032Speter part of the release proper, and isn't fully supported; in 883138032Speter particular, it does not run on System V based systems and 883238032Speter never will. 883338032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 883438032Speter to allow rmail to compile on systems that don't have 883538032Speter function prototypes and systems that don't have snprintf. 883638032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 883738032Speter lists by transaction delay times so that addresses that 883838032Speter respond quickly get sent first. This is to prevent very 883938032Speter sluggish servers from delaying other peoples' mail. 884038032Speter Contributed by Tony Sanders of BSDI. 884138032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 884238032Speter of BSDI. This has a lot of comments to help people out. 884338032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 884438032Speter put this on the m4 command line. On GNU m4 (which 884538032Speter supports the __file__ primitive) you can run m4 in an 884638032Speter arbitrary directory -- use either: 884738032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 884838032Speter or 884938032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 885038032Speter On other versions of m4 that don't support __file__, you 885138032Speter can use: 885238032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 885338032Speter (Note the trailing slash on the _CF_DIR_ definition.) 885438032Speter Old versions of m4 will default to _CF_DIR_=.. for back 885538032Speter compatibility. 885638032Speter CONFIG: fix mail from <> so it will properly convert to 885738032Speter MAILER-DAEMON on local addresses. 885838032Speter CONFIG: fix code that was supposed to catch colons in host 885938032Speter names. Problem noted by John Gardiner Myers of CMU. 886038032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 886138032Speter From Paul Riddle of the University of Maryland, Baltimore 886238032Speter County. 886338032Speter CONFIG: Catch and reject "." as a host address. 886438032Speter CONFIG: Generalize domaintable to look up all domains, not 886538032Speter just unqualified ones. 886638032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 886738032Speter was never used and didn't work anyway. 886838032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 886938032Speter and d on all mailers in the UUCP class. 887038032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 887138032Speter look for an alias for "user+detail", then for "user+*", and 887238032Speter finally for "user". This is intended for forwarding mail 887338032Speter for system aliases such as root and postmaster to a 887438032Speter centralized hub. 887538032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 887638032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 887738032Speter The F=8 flag is also set on the "relay" mailer, since 887838032Speter this is expected to be another sendmail. 887938032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 888038032Speter the name of the UUCP_RELAY -- in some cases, this is the 888138032Speter wrong value (e.g., when we have local UUCP connections), 888238032Speter and this can create unreplyable addresses. From Chip 888338032Speter Rosenthal of Unicom. 888438032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 888564562Sgshapiro Received: header inserted into all messages. Suggested by 888638032Speter Gary Mills of the University of Manitoba. 888738032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 888843730Speter to get the old behavior. I did this upon observing 888938032Speter that almost everyone needed this feature, and that the 889038032Speter concept I was trying to make happen didn't work with 889138032Speter some user agents anyway. FEATURE(notsticky) still works, 889238032Speter but it is a no-op. 889338032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 889438032Speter names are sent, rather than immediately diagnosing them 889538032Speter as User Unknown. 889638032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 889738032Speter and RELAY_MAILER_ARGS to set the arguments for the 889838032Speter indicated mailers. All default to "IPC $h". Patch from 889938032Speter Larry Parmelee of Cornell University. 890038032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 890138032Speter on the client side" and F=P to get an appropriate 890238032Speter return-path. From Kimmo Suominen. 890338032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 890438032Speter as the local mailer. For addresses of the form "user+detail" 890538032Speter the "detail" part is passed to procmail via the -a flag. 890638032Speter Contributed by Kimmo Suominen. 890738032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 890838032Speter use from mailertables. This lets you execute arbitrary 890938032Speter procmail scripts. Contributed by Kimmo Suominen. 891038032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 891138032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 891238032Speter Paul Southworth of CICNet Systems Support. 891338032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 891438032Speter This causes the null return path to be rewritten as 891538032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 891638032Speter From Michael Hohmuth of Technische Universitat Dresden. 891738032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 891838032Speter list us as the best possible MX record to be treated as 891938032Speter though they were local (essentially, assume that they 892038032Speter are included in $=w). This can cause additional DNS 892138032Speter traffic, but is easier to administer if this fits your 892238032Speter local model. It does not work reliably if there are 892338032Speter multiple hosts that share the best MX preference. 892438032Speter Code contributed by John Oleynick of Rutgers. 892538032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 892638032Speter SHell) instead of /bin/sh as the program used for delivery 892738032Speter to programs. If an argument is included, it is used as 892838032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 892938032Speter assumed. 893038032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 893138032Speter size of messages to the local and procmail mailers 893238032Speter respectively. Contributed by Brad Knowles of the Defense 893338032Speter Information Systems Agency. 893438032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 893538032Speter (just like text outside of angle brackets) in order to 893638032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 893738032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 893838032Speter any real systems any more) and tweak the DOMAIN macro 893938032Speter so that it is less likely that users will accidentally use 894038032Speter the Berkeley defaults. Also, create some generic files 894138032Speter that really can be used in the real world. 894238032Speter CONFIG: Add new configuration macros to set character sets for 894338032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 894438032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 894538032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 894638032Speter The old name will still be accepted for a while at least. 894738032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 894838032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 894938032Speter As with all relays, it can be ``mailer:hostname''. Suggested 895038032Speter by Scott Hutton. 895138032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 895238032Speter by Barb Dijker of Labyrinth Computer Services. 895338032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 895438032Speter performance for large alias files, and this confused many 895538032Speter people. 895638032Speter CONFIG: Add confCF_VERSION to append local information to the 895738032Speter configuration version number displayed during SMTP startup. 895838032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 895938032Speter would only work when locally addressed. Fix from 896038032Speter Edvard Tuinder of Cistron Internet Services. 896138032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 896243730Speter "n" (CheckAliases) is set when rebuilding alias database. 896338032Speter Based on code contributed by Claude Marinier. 896438032Speter CONFIG: Allow mailertable to have values of the form 896538032Speter ``error:code message''. The ``code'' is a status code 896638032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 896738032Speter Contributed by David James <dwj@agw.bt.co.uk>. 896838032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 896938032Speter sender domains that will be replaced with the masquerade name. 897038032Speter These domains will not be treated as local, but if mail passes 897138032Speter through with sender addresses in those domains they will be 897238032Speter replaced by the masquerade name. These can also be specified 897338032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 897438032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 897538032Speter as well as the header. Substantial improvements to this 897638032Speter code were contributed by Per Hedeland. 897738032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 897838032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 897938032Speter by Kimmo Suominen. 898038032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 898138032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 898238032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 898338032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 898438032Speter UUCP addressing.

This caused UnixWare 912738032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 912838032Speter Novell Labs Europe. 912938032Speter Fix problem with static linking of local getopt routine when 913038032Speter using GNU's ld command. Fix from John Kennedy of 913138032Speter Cal State Chico. 913238032Speter It was possible to turn off privacy flags. Problem noted by 913338032Speter *Hobbit*. 913438032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 913538032Speter and Liudvikas Bukys. 913638032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 913738032Speter from Spider Boardman. 913838032Speter CONFIG: No changes (version number only, to keep it in sync 913938032Speter with the binaries). 914038032Speter 914164562Sgshapiro8.6.10/8.6.10 1995/02/10 914238032Speter SECURITY: Diagnose bogus values to some command line flags that 914338032Speter could allow trash to get into headers and qf files. 914438032Speter Validate the name of the user returned by the IDENT protocol. 914538032Speter Some systems that really dislike IDENT send intentionally 914638032Speter bogus information. Problem pointed out by Michael Bushnell 914738032Speter of the Free Software Foundation. Has some security 914838032Speter implications. 914938032Speter Fix a problem causing error messages about DNS problems when 915038032Speter the host name contained a percent sign to act oddly 915138032Speter because it was passed as a printf-style format string. 915238032Speter In some cases this could cause core dumps. 915338032Speter Avoid possible buffer overrun in returntosender() if error 915438032Speter message is quite long. From Fletcher Mattox of the 915538032Speter University of Texas. 915638032Speter Fix a problem that would silently drop "too many hops" error 915738032Speter messages if and only if you were sending to an alias. 915838032Speter From Jon Giltner of the University of Colorado and 915938032Speter Dan Harton of Oak Ridge National Laboratory. 916038032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 916138032Speter set and e->e_message was null. Fix from Bruce Nagel of 916238032Speter Data General. 916338032Speter Fix problem that can still cause df files to be left around 916438032Speter after "hop count exceeded" messages. Fix from Andrew 916538032Speter Chang and Shau-Ping Lo of SunSoft. 916638032Speter Fix a problem that can cause buffer overflows on very long 916738032Speter user names (as might occur if you piped to a program 916838032Speter with a lot of arguments). 916938032Speter Avoid returning an error and re-queueing if the host signature 917038032Speter is null; this can occur on addresses like ``user@.''. 917138032Speter Problem noted by Wesley Craig and the University of 917238032Speter Michigan. 917338032Speter Avoid possible calls to malloc(0) if MCI caching is turned 917438032Speter off. Bug fix from Pierre David of the Laboratoire 917538032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 917638032Speter Universite de Versailles - St Quentin, and Jacky 917738032Speter Thibault. 917838032Speter Make a local copy of the line being sent via senttolist() -- in 917938032Speter some cases, buffers could get trashed by map lookups 918038032Speter causing it to do unexpected things. This also simplifies 918138032Speter some of the map code. 918238032Speter CONFIG: No changes (version number only, to keep it in sync 918338032Speter with the binaries). 918438032Speter 918564562Sgshapiro8.6.9/8.6.9 1994/04/19 918638032Speter Do all mail delivery completely disconnected from any terminal. 918738032Speter This provides consistency with daemon delivery and 918838032Speter may have some security implications. 918938032Speter Make sure that malloc doesn't get called with zero size, 919038032Speter since that fails on some systems. Reported by Ed 919138032Speter Hill of the University of Iowa. 919238032Speter Fix multi-line values for $e (SMTP greeting message). Reported 919338032Speter by Mike O'Connor of Ford Motor Company. 919438032Speter Avoid syserr if no NIS domain name is defined, but the map it 919538032Speter is trying to open is optional. From Win Bent of USC. 919638032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 919738032Speter Hesiod support for UDB from Todd Miller of the University of 919838032Speter Colorado. Use "hesiod" as the service name in the U 919938032Speter option. 920038032Speter Fix a problem that failed to set the "authentic" host name (that 920138032Speter is, the one derived from the socket info) if you called 920238032Speter sendmail -bs from inetd. Based on code contributed by 920338032Speter Todd Miller (this problem was also reported by Guy Helmer 920438032Speter of Dakota State University). This also fixes a related 920538032Speter problem reported by Liudvikas Bukys of the University of 920638032Speter Rochester. 920738032Speter Parameterize "nroff -h" in all the Makefiles so people with 920838032Speter variant versions can use them easily. Suggested by 920938032Speter Peter Collinson of Hillside Systems. 921038032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 921138032Speter spaces between parameters instead of one. Reported by 921238032Speter Valdis Kletnieks of Virginia Tech. 921338032Speter Reduce the number of system calls during message collection by 921438032Speter using global timeouts around the collect() loop. This 921538032Speter code was contributed by Eric Wassenaar. 921638032Speter If the initial hostname name gathering results in a name 921738032Speter without a dot (usually caused by NIS misconfiguration) 921838032Speter and BIND is compiled in, directly access DNS to get 921938032Speter the canonical name. This should make life easier for 922038032Speter Solaris systems. If it still can't be resolved, and 922138032Speter if the name server is listed as "required", try again 922238032Speter in 30 seconds. If that also fails, exit immediately to 922338032Speter avoid bogus "config error: mail loops back to myself" 922438032Speter messages. 922538032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 922638032Speter message to explain how much space was available and 922738032Speter sound a bit less threatening. Suggested by Stan Janet 922838032Speter of the National Institute of Standards and Technology. 922938032Speter If mail is delivered to an alias that has an owner, deliver any 923038032Speter requested return-receipt immediately, and strip the 923138032Speter Return-Receipt-To: header from the subsequent message. 923238032Speter This prevents a certain class of denial of service 923338032Speter attack, arguably gives more reasonable semantics, and 923438032Speter moves things more towards what will probably become a 923538032Speter network standard. Suggested by Christopher Davis of 923638032Speter Kapor Enterprises. 923738032Speter Add a "noreceipts" privacy flag to turn off all return receipts 923838032Speter without recompiling. 923938032Speter Avoid printing ESMTP parameters as part of the error message 924038032Speter if there are errors during parsing. This change is 924138032Speter purely cosmetic. 924238032Speter Avoid sending out error messages during the collect phase of 924338032Speter SMTP; there is an MVS mailer from UCLA that gets 924438032Speter confused by this. Of course, I think it's their bug.... 924538032Speter Check for the $j macro getting undefined, losing a dot, or getting 924638032Speter lost from $=w in the daemon before accepting a connection; 924738032Speter if it is, it dumps state, prints a LOG_ALERT message, 924838032Speter and drops core for debugging. This is an attempt to 924938032Speter track down a bug that I thought was long since gone. 925038032Speter If you see this, please forward the log fragment to 925138032Speter sendmail@sendmail.ORG. 925238032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 925338032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 925438032Speter Wolfhugel. 925538032Speter Instead of trying to truncate the listen queue for the server 925638032Speter SMTP port when the load average is too high, just close 925738032Speter the port completely and reopen it later as needed. 925838032Speter This ensures that the other end gets a quick "connection 925938032Speter refused" response, and that the connection can be 926038032Speter recovered later. In particular, some socket emulations 926138032Speter seem to get confused if you tweak the listen queue 926238032Speter size around and can never start listening to connections 926338032Speter again. The down side is that someone could start up 926438032Speter another daemon process in the interim, so you could 926538032Speter have multiple daemons all not listening to connections; 926638032Speter this could in turn cause the sendmail.pid file to be 926738032Speter incorrect. A better approach might be to accept the 926838032Speter connection and give a 421 code, but that could break 926943730Speter other mailers in mysterious ways and have paging behavior 927038032Speter implications. 927138032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 927238032Speter set debugging on the wrong socket. From Eric Wassenaar. 927338032Speter When creating a df* temporary file, be sure you truncate any 927438032Speter existing data in the file -- otherwise system crashes 927538032Speter and the like could result in extra data being sent. 927638032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 927738032Speter doc directory. This includes some additional 927838032Speter information. 927938032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 928038032Speter of recipient envelope addresses. This should have been 928138032Speter handled by the $&h trick, but broke if people were 928238032Speter mixing domainized and UUCP addresses. They should 928338032Speter probably have converted all the way over to uucp-uudom 928438032Speter instead of uucp-{new,old}, but the failure mode was to 928538032Speter loop the mail, which was bad news. 928638032Speter Portability fixes: 928738032Speter Newer BSDI systems (several people). 928838032Speter Older BSDI systems from Christophe Wolfhugel. 928938032Speter Intergraph CLIX, from Paul Southworth of CICNet. 929038032Speter UnixWare, from Evan Champion. 929138032Speter NetBSD from Adam Glass. 929238032Speter Solaris from Quentin Campbell of the University of 929338032Speter Newcastle upon Tyne. 929438032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 929538032Speter Corporation. 929638032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 929738032Speter SunOS (it has setsid() and setvbuf() calls) from 929838032Speter Jonathan Kamens of OpenVision Technologies. 929938032Speter HP-UX from Tor Lillqvist. 930038032Speter New Files: 930138032Speter src/Makefile.CLIX 930238032Speter src/Makefile.NCR3000 930338032Speter doc/changes/Makefile 930438032Speter doc/changes/changes.me 930538032Speter doc/changes/changes.ps 930638032Speter 930764562Sgshapiro8.6.8/8.6.6 1994/03/21 930838032Speter SECURITY: it was possible to read any file as root using the 930938032Speter E (error message) option. Reported by Richard Jones; 931038032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 931138032Speter 931264562Sgshapiro8.6.7/8.6.6 1994/03/14 931338032Speter SECURITY: it was possible to get root access by using weird 931438032Speter values to the -d flag. Thanks to Alain Durand of 931538032Speter INRIA for forwarding me the notice from the bugtraq 931638032Speter list. 931738032Speter 931864562Sgshapiro8.6.6/8.6.6 1994/03/13 931938032Speter SECURITY: the ability to give files away on System V-based 932038032Speter systems proved dangerous -- don't run as the owner 932138032Speter of a :include: file on a system that allows giveaways. 932238032Speter Unfortunately, this also applies to determining a 932338032Speter valid shell. 932438032Speter IMPORTANT: Previous versions weren't expiring old connections 932538032Speter in the connection cache for a long time under some 932638032Speter circumstances. This could result in resource exhaustion, 932738032Speter both at your end and at the other end. This checks the 932838032Speter connections for timeouts much more frequently. From 932938032Speter Doug Anderson of NCSC. 933038032Speter Fix a glitch that snuck in that caused programs to be run as 933138032Speter the sender instead of the recipient if the mail was 933238032Speter from a local user to another local user. From 933338032Speter Motonori Nakamura of Kyoto University. 933438032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 933538032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 933638032Speter Bryan Costales of ICSI. 933738032Speter Change the method used to declare the "statfs" availability; 933838032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 933938032Speter tweaking in conf.c, there is a single #define called 934038032Speter SFS_TYPE which takes on one of six values (SFS_NONE 934138032Speter for no statfs availability, SFS_USTAT for the ustat(2) 934238032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 934338032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 934438032Speter statfs(2) call with the declarations in <sys/vfs.h>, 934538032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 934638032Speter Fix glitch in NetInfo support that could return garbage if 934738032Speter there was no "/locations/sendmail" property. From 934838032Speter David Meyer of the University of Virginia. 934938032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 935038032Speter to allow Linux to turn it off even though it is a 935138032Speter BSD-like system. 935238032Speter Allow setting of "ident" timeout to zero to turn off the ident 935338032Speter protocol entirely. 935438032Speter Make 7-bit stripping local to a connection (instead of to a 935538032Speter mailer); this allows you to specify that SMTP is a 935638032Speter 7-bit channel, but revert to 8-bit should it advertise 935738032Speter that it supports 8BITMIME. You still have to specify 935838032Speter mailer flag 7 to get this stripping at all. 935938032Speter Improve makesendmail script so it handles more cases automatically. 936038032Speter Tighten up restrictions on taking ownership of :include: files 936138032Speter to avoid problems on systems that allow you to give away 936238032Speter files. 936338032Speter Fix a problem that made it impossible to rebuild the alias 936438032Speter file if it was on a read-only file system. From 936538032Speter Harry Edmon of the University of Washington. 936638032Speter Improve MX randomization function. From John Gardiner Myers 936738032Speter of CMU. 936838032Speter Fix a minor glitch causing a bogus message to be printed (used 936938032Speter %s instead of %d in a printf string for the line number) 937038032Speter when a bad queue file was read. From Harry Edmon. 937138032Speter Allow $s to remain NULL on locally generated mail. I'm not 937238032Speter sure this is necessary, but a lot of people have complained 937338032Speter about it, and there is a legitimate question as to whether 937438032Speter "localhost" is legal as an 822-style domain. 937538032Speter Fix a problem with very short line lengths (mailer L= flag) in 937638032Speter headers. This causes a leading space to be added onto 937738032Speter continuation lines (including in the body!), and also 937838032Speter tries to wrap headers containing addresses (From:, To:, 937938032Speter etc) intelligently at the shorter line lengths. Problem 938038032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 938138032Speter Log the real user name when logging syserrs, since these can have 938238032Speter security implications. Suggested by several people. 938338032Speter Fix address logging of cached connections -- it used to always 938438032Speter log the numeric address as zero. This is a somewhat 938538032Speter bogus implementation in that it does an extra system 938638032Speter call, but it should be an inexpensive one. Fix from 938738032Speter Motonori Nakamura. 938838032Speter Tighten up handling of short syslog buffers even more -- there 938938032Speter were cases where the outgoing relay= name was too long 939038032Speter to share a line with delay= and mailer= logging. 939138032Speter Limit the overhead on split envelopes to one open file descriptor 939238032Speter per envelope -- previously the overhead was three 939338032Speter descriptors. This was in response to a problem reported 939438032Speter by P{r (Pell) Emanuelsson. 939538032Speter Fixes to better handle the case of unexpected connection closes; 939638032Speter this redirects the output to the transcript so the info 939738032Speter is not lost. From Eric Wassenaar. 939838032Speter Fix potential string overrun if you macro evaluate a string that 939938032Speter has a naked $ at the end. Problem noted by James Matheson 940038032Speter <jmrm@eng.cam.ac.uk>. 940138032Speter Make default error number on $#error messages 553 (``Requested 940238032Speter action not taken: mailbox name not allowed'') instead of 940338032Speter 501 (``Syntax error in parameters or arguments'') to 940438032Speter avoid bogus "protocol error" messages. 940538032Speter Strip off any existing trailing dot on names during $[ ... $] 940638032Speter lookup. This prevents it from ending up with two dots 940738032Speter on the end of dot terminated names. From Wesley Craig 940838032Speter of the University of Michigan and Bryan Costales of ICSI. 940938032Speter Clean up file class reading so that the debugging information is 941038032Speter more informative. It hadn't been using setclass, so you 941138032Speter didn't see the class items being added. 941238032Speter Avoid core dump if you are running a version of sendmail where 941338032Speter NIS is compiled in, and you specify an NIS map, but 941438032Speter NIS is not running. Fix from John Oleynick of 941538032Speter Rutgers. 941638032Speter Diagnose bizarre case where res_search returns a failure value, 941738032Speter but sets h_errno to a success value. 941838032Speter Make sure that "too many hops" messages are considered important 941938032Speter enough to send an error to the Postmaster (that is, the 942038032Speter address specified in the P option). This fix should 942138032Speter help problems that cause the df file to be left around 942238032Speter sometimes -- unfortunately, I can't seem to reproduce 942338032Speter the problem myself. 942438032Speter Avoid core dump (null pointer reference) on EXPN command; this 942538032Speter only occurred if your log level was set to 10 or higher 942638032Speter and the target account was an alias or had a .forward file. 942738032Speter Problem noted by Janne Himanka. 942838032Speter Avoid "denial of service" attacks by someone who is flooding your 942938032Speter SMTP port with bad commands by shutting the connection 943038032Speter after 25 bad commands are issued. From Kyle Jones of 943138032Speter UUNET. 943238032Speter Fix core dump on error messages with very long "to" buffers; 943338032Speter fmtmsg overflows the message buffer. Fixed by trimming 943438032Speter the to address to 203 characters. Problem reported by 943538032Speter John Oleynick. 943638032Speter Fix configuration for HASFLOCK -- there were some spots where 943738032Speter a #ifndef was incorrectly #ifdef. Pointed out by 943838032Speter George Baltz of the University of Maryland. 943938032Speter Fix a typo in savemail() that could cause the error message To: 944038032Speter lists to be incorrect in some places. From Motonori 944138032Speter Nakamura. 944238032Speter Fix a glitch that can cause duplicate error messages on split 944338032Speter envelopes where an address on one of the lists has a 944438032Speter name server failure. Fix from Voradesh Yenbut of the 944538032Speter University of Washington. 944638032Speter Fix possible bogus pointer reference on ESMTP parameters that 944738032Speter don't have an ``=value'' part. 944838032Speter CNAME loops caused an error message to be generated, but also 944938032Speter re-queued the message. Changed to just re-queue the 945038032Speter message (it's really hard to just bounce it because 945138032Speter of the weird way the name server works in the presence 945238032Speter of CNAME loops). Problem noted by James M.R.Matheson 945338032Speter of Cambridge University. 945438032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 945538032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 945638032Speter user name. Suggested by Andreas Stolcke of ICSI. 945738032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 945838032Speter override it easily in the Makefile -- that is, you can 945938032Speter turn it off using -DNAMED_BIND=0. 946038032Speter If a gethostbyname(...) of an address with a trailing dot fails, 946138032Speter try it without the trailing dot. This is because if 946238032Speter you have a version of gethostbyname() that falls back 946338032Speter to NIS or the /etc/hosts file it will fail to find 946438032Speter perfectly reasonable names that just don't happen to 946538032Speter be dot terminated in the hosts file. You don't want to 946638032Speter strip the dot first though because we're trying to ensure 946738032Speter that country names that match one of your subdomains get 946838032Speter a chance. 946938032Speter PRALIASES: fix bogus output on non-null-terminated strings. 947038032Speter From Bill Gianopoulos of Raytheon. 947138032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 947238032Speter This was in code intended to only catch the self-literal 947338032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 947438032Speter IP address), but the code was broken. However, it will 947538032Speter still do this if $M is defined; this is necessary to 947638032Speter get client configurations to work (sigh). Note that this 947738032Speter means that $M overrides :mailname entries in the user 947838032Speter database! Problem noted by Paul Southworth. 947938032Speter CONFIG: Fix definition of Solaris help file location. From 948038032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 948138032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 948238032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 948338032Speter and USENET_MAILER_MAX to tweak the maximum message 948438032Speter size for various mailers. 948538032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 948638032Speter instead of assuming that it is "inews" for consistency 948738032Speter with other mailers. From Michael Corrigan of UC San Diego. 948838032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 948938032Speter qualify the address in the SMTP envelope as user@{relay|hub} 949038032Speter instead of user@$j. From Bill Wisner of The Well. 949138032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 949238032Speter CONFIG: Don't turn off case mapping of user names in the local 949338032Speter mailer for IRIX. This was different than most every other 949438032Speter system. 949538032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 949638032Speter envelope. Noted by Thierry Besancon 949738032Speter <besancon@excalibur.ens.fr>. 949838032Speter CONFIG: Don't include -z by default on uux line -- most systems 949938032Speter don't want it set by default. Pointed out by Philippe 950038032Speter Michel of Thomson CSF. 950138032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 950238032Speter host name was foo.bar.ray.com and you matched against 950338032Speter ".ray.com", the old implementation bound %1 to "bar" 950438032Speter instead of "foo.bar". Also, allow "." in the mailertable 950538032Speter to match anything -- essentially, take over SMART_HOST. 950638032Speter This also moves matching of explicit local host names 950738032Speter before the mailertable so they don't have to be special 950838032Speter cased in the mailertable data. Reported by Bill 950938032Speter Gianopoulos of Raytheon; the fix for the %1 binding 951038032Speter problem was contributed by Nicholas Comanos of the 951138032Speter University of Sydney. 951238032Speter CONFIG: Don't include "root" in class $=L (users to deliver 951338032Speter locally, even if a hub or relay exists) by default. 951438032Speter This is because of the known bug where definition of 951538032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 951638032Speter both and deliver into the local mailbox. 951738032Speter CONFIG: Move up bitdomain and uudomain handling so that they 951838032Speter are done before .UUCP class matching; uudomain was 951938032Speter reported as ineffective before. This also frees up 952038032Speter diversion 8 for future use. Problem reported by Kimmo 952138032Speter Suominen. 952238032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 952338032Speter into host names. As pointed out by Jonathan Kamens, 952438032Speter these are often used because either the forward or reverse 952538032Speter mapping is broken; this translation makes it broken again. 952638032Speter DOC: Clarify $@ and $: in the Install & Op Guide.

From 955338032Speter Bob Campbell at U.C. Berkeley. 955438032Speter Security fix: group ids were not completely set when programs 955538032Speter were invoked. This caused programs to have group 955638032Speter permissions they should not have had (usually group 955738032Speter daemon instead of their own group). In particular, 955838032Speter Perl scripts would refuse to run. 955938032Speter Security: check to make sure files that are written are not 956038032Speter symbolic links (at least under some circumstances). 956138032Speter Although this does not respond to a specific known 956238032Speter attack, it's just a good idea. Suggested by 956338032Speter Christian Wettergren. 956438032Speter Security fix: if a user had an NFS mounted home directory on 956538032Speter a system with a restricted shell listed in their 956638032Speter /etc/passwd entry, they could still execute any 956738032Speter program by putting that in their .forward file. 956838032Speter This fix prevents that by insisting that their shell 956938032Speter appear in /etc/shells before allowing a .forward to 957038032Speter execute a program or write a file. You can disable 957138032Speter this by putting "*" in /etc/shells. It also won't 957238032Speter permit world-writable :include: files to reference 957338032Speter programs or files (there's no way to disable this). 957443730Speter These behaviors are only one level deep -- for 957538032Speter example, it is legal for a world-writable :include: 957638032Speter file to reference an alias that writes a file, on 957738032Speter the assumption that the alias file is well controlled. 957838032Speter Security fix: root was not treated suspiciously enough when 957938032Speter looking into subdirectories. This would potentially 958038032Speter allow a cracker to examine files that were publicly 958138032Speter readable but in a non-publicly searchable directory. 958238032Speter Fix a problem that causes an error on QUIT on a cached 958338032Speter connection to create problems on the current job. 958438032Speter These are typically unrelated, so errors occur in 958538032Speter the wrong place. 958638032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 958738032Speter runs more responsive to load average, and fixes a 958838032Speter problem that ignored the load average in locally 958938032Speter generated mail. From Eric Wassenaar. 959038032Speter Fix possible core dump on aliases with null LHS. From 959138032Speter John Orthoefer of BB&N. 959238032Speter Revert to using flock() whenever possible -- there are just 959338032Speter too many bugs in fcntl() locking, particularly over 959438032Speter NFS, that cause sendmail to fail in perverse ways. 959538032Speter Fix a bug that causes the connection cache to get confused 959638032Speter when sending error messages. This resulted in 959738032Speter "unexpected close" messages. It should fix itself 959838032Speter on the following queue run. Problem noted by 959938032Speter Liudvikas Bukys of the University of Rochester. 960038032Speter Include $k in $=k as documented in the Install & Op Guide. 960138032Speter This seems odd, but it was documented.... From 960238032Speter Michael Corrigan of UCSD. 960338032Speter Fix problem that caused :include:s from alias files to be 960438032Speter forced to be owned by root instead of daemon 960538032Speter (actually DefUid). From Tim Irvin. 960638032Speter Diagnose unrecognized I option values -- from Mortin Forssen 960738032Speter of the Chalmers University of Technology. 960838032Speter Make "error" mailer work consistently when there is no error 960938032Speter code associated with it -- previously it returned OK 961038032Speter even though there was a real problem. Now it assumes 961138032Speter EX_UNAVAILABLE. 961238032Speter Fix bug that caused the last header line of messages that had 961338032Speter no body and which were terminated with EOF instead of 961438032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 961538032Speter Fix core dump on SMTP mail to programs that failed -- it tried 961638032Speter to go to a "next MX host" when none existed, causing 961738032Speter a core dump. From der Mouse at McGill University. 961838032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 961938032Speter this makes it easier to turn it off (using 962038032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 962138032Speter Fix YP_MASTER_NAME store to use the unupdated result of 962238032Speter gethostname() (instead of myhostname(), which tries 962338032Speter to fully qualify the name) to be consistent with 962438032Speter SunOS. If your hostname is unqualified, this fixes 962538032Speter transfers to slave servers. Bug noted by Keith 962638032Speter McMillan of Ameritech Services, Inc. 962738032Speter Fix Ultrix problem: gethostbyname() can return a very large 962838032Speter (> 500) h_length field, which causes the sockaddr 962938032Speter to be trashed. Use the size of the sockaddr instead. 963038032Speter Fix from Bob Manson of Ohio State. 963138032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 963238032Speter defined -- this confuses gethostbyname on hosts 963338032Speter file lookups, which doesn't understand the trailing 963438032Speter dot convention. 963538032Speter Log SMTP server subprocesses that die with a signal instead 963638032Speter of from a clean exit. 963738032Speter If you don't have option "I" set, don't assume that a DNS 963838032Speter "host unknown" message is authoritative -- it 963938032Speter might still be found in /etc/hosts. 964038032Speter Fix a problem that would cause Deferred: messages to be sent 964138032Speter as the subject of an error message, even though the 964238032Speter actual cause of a message was more severe than that. 964338032Speter Problem noted by Chris Seabrook of OSSI. 964438032Speter Fix race condition in DBM alias file locking. From Kyle 964538032Speter Jones of UUNET. 964638032Speter Limit delivery syslog line length to avoid bugs in some 964738032Speter versions of syslog(3). This adds a new compile time 964838032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 964938032Speter University, which is in turn derived from IDA. 965038032Speter Fix quotes inside of comments in addresses -- previously 965138032Speter it insisted that they be balanced, but the 822 spec 965238032Speter says that they should be ignored. 965338032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 965438032Speter debugging). This also evaluates ruleset 89, if set 965538032Speter (with the null input), and logs the result. This 965638032Speter should be used sparingly, since the rewrite process 965738032Speter is not reentrant. 965838032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 965938032Speter documented in the Bat Book. 966038032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 966138032Speter return an error message and did not requeue the message. 966238032Speter Fix based on code from Roland Dirlewanger of 966338032Speter Reseau Regional Aquarel, Bordeaux, France. 966438032Speter Fix a problem that caused a seg fault if you got a 421 error 966538032Speter code during some parts of connection initialization. 966638032Speter I've only seen this when talking to buggy mailers on 966738032Speter the other end, but it shouldn't give a seg fault in 966838032Speter any case.

Noted by William C Fenner of 971038032Speter the NRL Connection Machine Facility. 971138032Speter Fix a problem that could cause a core dump if the input sequence 971238032Speter had (or somehow acquired) a \231 character. 971338032Speter Make sure that route-addrs always have <angle brackets> around 971438032Speter them in non-SMTP envelopes (SMTP envelopes already do 971538032Speter this properly). 971638032Speter Avoid weird headers on unbalanced punctuation of the form: 971738032Speter ``Joe User <user)'' -- this caused reference to the 971838032Speter null macro. Fix from Rick McCarty of IO.COM. 971938032Speter Fix a problem that caused an alias "user: user@local.host" to 972038032Speter not have the QNOTREMOTE bit set; this caused configs 972138032Speter to act as if FEATURE(notsticky) was defined even when 972238032Speter it was not. The effect of the problem was to make it 972338032Speter very hard to to set up satellite sites that had a few 972438032Speter local accounts, with everything else forwarded to a 972538032Speter corporate hub. Reported by Detlef Drewanz of the 972638032Speter University of Rostock and Mark Frost of NCD. 972738032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 972838032Speter addresses. This is more efficient (fewer name server 972938032Speter calls) and fixes certain unusual configurations, such 973038032Speter as those that have ruleset 4 do something that is 973138032Speter non-idempotent unless a mailer-specific ruleset did 973238032Speter something else.

Briefly, if you are sending to host 980138032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 980238032Speter "foo!baz" remains "foo!baz", and anything else has 980338032Speter the local name prepended. 980438032Speter CONFIG: portability fixes for HP-UX. 980538032Speter DOC: several minor problems fixed in the Install & Op Guide. 980638032Speter MAKEMAP: fix core dump problem on lines that are too long or 980738032Speter which lack newline. From Mark Delany. 980838032Speter MAILSTATS: print sums of columns (total messages & kbytes 980938032Speter in and out of the system). From Tom Ferrin of UC 981038032Speter San Francisco Computer Graphics Lab. 981138032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 981238032Speter On HP-UX, /etc/sendmail.cf has been moved to 981338032Speter /usr/lib/sendmail.cf to match HP sendmail. 981438032Speter Permissions have been tightened up on world-writable 981538032Speter :include: files and accounts that have shells 981638032Speter that are not listed in /etc/shells. This may 981738032Speter cause some .forward files that have worked 981838032Speter before to start failing. 981938032Speter SIGUSR1 dumps some state to the log. 982038032Speter NEW FILES: 982138032Speter src/Makefile.DGUX 982238032Speter src/Makefile.Dynix 982338032Speter src/Makefile.FreeBSD 982438032Speter src/Makefile.Mach386 982538032Speter src/Makefile.NetBSD 982638032Speter src/Makefile.RISCos 982738032Speter src/Makefile.SCO 982838032Speter src/Makefile.SVR4 982938032Speter src/Makefile.Titan 983038032Speter cf/mailer/pop.m4 983138032Speter cf/ostype/bsdi1.0.m4 983238032Speter cf/ostype/dgux.m4 983338032Speter cf/ostype/dynix3.2.m4 983438032Speter cf/ostype/sco3.2.m4 983538032Speter makemap/Makefile.dist 983638032Speter praliases/Makefile.dist 983738032Speter 983864562Sgshapiro8.6.4/8.6.4 1993/10/31 983938032Speter Repair core-dump problem (write to read-only memory segment) 984038032Speter if you fall back to the return-to-Postmaster case in 984138032Speter savemail. Problem reported by Richard Liu. 984238032Speter Immediately diagnose bogus sender addresses in SMTP. This 984338032Speter makes quite certain that crackers can't use this 984438032Speter class of attack. 984538032Speter Reliability Fix: check return value from fclose() and fsync() 984638032Speter in a few critical places. 984738032Speter Minor problem in initsys() that reversed a condition for 984838032Speter redirecting the output channel on queue runs. It's 984938032Speter not clear this code even does anything. From Eric 985038032Speter Wassenaar of the Dutch National Institute for Nuclear 985138032Speter and High-Energy Physics. 985238032Speter Fix some problems that caused queue runs to do "too much work", 985338032Speter such as double-reading the Errors-To: header. From 985438032Speter Eric Wassenaar. 985538032Speter Error messages on writing the temporary file (including the 985638032Speter data file) were getting suppressed in SMTP -- this 985738032Speter fix causes them to be properly reported. From Eric 985838032Speter Wassenaar. 985938032Speter Some changes to support AF_UNIX sockets -- this will only 986038032Speter really become relevant in the next release, but some 986138032Speter people need it for local patches. From Michael 986238032Speter Corrigan of UC San Diego. 986338032Speter Use dynamically allocated memory (instead of static buffers) 986438032Speter for macros defined in initsys() and settime(); since 986538032Speter these can have different values depending on which 986638032Speter envelope they are in. From Eric Wassenaar. 986738032Speter Improve logging to show ctladdr on to= logging; this tells you 986838032Speter what uid/gid processes ran as. 986938032Speter Fix a problem that caused error messages to be discarded if 987038032Speter the sender address was unparseable for some reason; 987138032Speter this was supposed to fall back to the "return to 987238032Speter postmaster" case. 987338032Speter Improve aliaswait backoff algorithm. 987438032Speter Portability patches for Linux (8.6.3 required another header 987538032Speter file) (from Karl London) and SCO UNIX. 987638032Speter CONFIG: patch prog mailer to not strip host name off of envelope 987738032Speter addresses (so that it matches local again). From 987838032Speter Christopher Davis. 987938032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 988038032Speter this prevents uux from seeing lines with null names like 988138032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 988238032Speter Nakamura of Kyoto University. 988338032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 988438032Speter it shouldn't fail miserably. From Motonori Nakamura. 988538032Speter 988664562Sgshapiro8.6.2/8.6.2 1993/10/15 988738032Speter Put a "successful delivery" message in the transcript for 988838032Speter addresses that get return-receipts. 988938032Speter Put a prominent "this is only a warning" message in warning 989038032Speter messages -- some people don't read carefully enough 989138032Speter and end up sending the message several times. 989238032Speter Include reason for temporary failure in the "warning" return 989338032Speter message. Currently, it just says "cannot send for 989438032Speter four hours". 989538032Speter Fix the "Original message received" time generated for 989638032Speter returntosender messages. It was previously listed as 989738032Speter the current time. Bug reported by Eric Hagberg of 989838032Speter Cornell University Medical College. 989938032Speter If there is an error when writing the body of a message, 990038032Speter don't send the trailing dot and wait for a response 990138032Speter in sender SMTP, as this could cause the connection to 990238032Speter hang up under some bizarre circumstances. From Eric 990338032Speter Wassenaar. 990438032Speter Fix some server SMTP synchronization problems caused when 990538032Speter connections fail during message collection. From 990638032Speter Eric Wassenaar. 990738032Speter Fix a problem that can cause srvrsmtp to reject mail if the 990838032Speter name server is down -- it accepts the RCPT but rejects 990938032Speter the DATA command. Problem reported by Jim Murray of 991038032Speter Stratus. 991138032Speter Fix a problem that can cause core dumps if the config file 991238032Speter incorrectly resolves to a null hostname. Reported by 991338032Speter Allan Johannesen of WPI. 991438032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 991538032Speter by non-root users were not put into 991638032Speter X-Authentication-Warning:s as intended because the 991743730Speter config file hadn't set the PrivacyOptions yet. Fix 991838032Speter from Sven-Ove Westberg of the University of Lulea. 991938032Speter Under very odd circumstances, the alias file rebuild code 992038032Speter could get confused as to whether a database was 992138032Speter open or not. 992238032Speter Check "vendor code" on the end of V lines -- this is 992338032Speter intended to provide a hook for vendor-specific 992438032Speter configuration syntax. (This is a "new feature", 992538032Speter but I've made an exception to my rule in a belief 992638032Speter that this is a highly exceptional case.) 992738032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 992838032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 992938032Speter (from Jon Forrest of UC Berkeley) 993038032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 993138032Speter 993264562Sgshapiro8.6.1/8.6 1993/10/08 993338032Speter Portability fixes for A/UX and Encore UMAX V. 993438032Speter Fix error message handling -- if you had a name server down 993538032Speter causing an error during parsing, that message was never 993638032Speter propagated to the queue file. 993738032Speter 993864562Sgshapiro8.6/8.6 1993/10/05 993938032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 994038032Speter conf.h (other systems have the same bug). 994138032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 994238032Speter getdtablesize() instead of sysconf(); a disturbingly 994338032Speter large number of systems defined _SC_OPEN_MAX in the 994438032Speter header files but don't have the syscall. 994538032Speter Another patch to really truly ignore MX records in getcanonname 994638032Speter if trymx == FALSE. 994738032Speter Fix problem that caused the "250 IAA25499 Message accepted for 994838032Speter delivery" message to be omitted if there was an error 994938032Speter in the header of the message (e.g., a bad Errors-To: 995038032Speter line). Pointed out by Michael Corrigan of UCSD. 995138032Speter Announce name of host we are chatting when we get errors; this 995238032Speter is an IDA-ism suggested by Christophe Wolfhugel. 995338032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 995438032Speter Australian Artificial Intelligence Institute), SCO Unix 995538032Speter (from Murray Kucherawy of Hookup Communication Corp.), 995638032Speter NeXT (from Vince DeMarco and myself), Linux (from 995738032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 995838032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 995938032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 996038032Speter Some changes to get around gcc optimizer bugs. From Takahiro 996138032Speter Kanbe. 996238032Speter Fix error recovery in queueup if another tf file of the same 996338032Speter name already exists. Problem stumbled over by Bill 996438032Speter Wisner of The Well. 996538032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 996638032Speter Problem noted by Keith McMillan of Ameritech Services. 996738032Speter Deal with group permissions properly when opening .forward and 996838032Speter :include: files. This relaxes the 8.1C restrictions 996938032Speter slightly more. This includes proper setting of groups 997038032Speter when reading :include: files, allowing you to read some 997138032Speter files that you should be able to read but have previously 997238032Speter been denied unless you owned them or they had "other" 997338032Speter read permission. 997438032Speter Make certain that $j is in $=w (after the .cf is read) so that 997538032Speter if the user is forced to override some silly system, 997638032Speter MX suppression will still work. 997738032Speter Fix a couple of efficiency problems where newstr was double- 997838032Speter calling expensive routines. In at least one case, it 997938032Speter wasn't guaranteed that they would always return the 998038032Speter same result. Problem noted by Christophe Wolfhugel. 998138032Speter Fix null pointer dereference in putoutmsg -- only on an error 998238032Speter condition from a non-SMTP mailer. From Motonori 998338032Speter Nakamura. 998438032Speter Macro expand "C" line class definitions before scanning so that 998538032Speter "CX $Z" works. 998638032Speter Fix problem that caused error message to be sent while still 998738032Speter trying to send the original message if the connection 998838032Speter is closed during a DATA command after getting an error 998938032Speter on an RCPT command (pretty obscure). Problem reported 999038032Speter by John Myers of CMU. 999138032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 999238032Speter term bug. 999338032Speter Fix a nasty bug causing core dumps when returning the "warning: 999438032Speter cannot deliver for N hours -- will keep trying" message; 999543730Speter it only occurred if you had PostmasterCopy set and 999638032Speter only on some architectures. Although sendmail would 999738032Speter keep trying, it would send error messages on each 999838032Speter queue interval. This is an important fix. 999938032Speter Allow u and g options to take user and group names respectively. 1000038032Speter Don't do a chdir into the queue directory in -bt mode to make 1000138032Speter ruleset testing a bit easier. 1000238032Speter Don't allow users to turn off logging (using -oL) on the command 1000338032Speter line -- command line can only raise, not lower, logging 1000438032Speter level. 1000538032Speter Set $u to the original recipient on the SMTP transaction or on 1000638032Speter the command line. This is only done if there is exactly 1000738032Speter one recipient. Technically, this does not meet the 1000838032Speter specs, because it does not guarantee a domain on the 1000938032Speter address. 1001038032Speter Fix a problem that dumped error messages on bad addresses if 1001138032Speter you used the -t flag. Problem noted by Josh Smith of 1001238032Speter Harvey Mudd College. 1001338032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 1001438032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 1001538032Speter avoid the problem of people who use angle brackets in 1001638032Speter their full name information. 1001738032Speter Fix a null pointer dereference if you set option "l", have 1001838032Speter an Errors-To: header in the message, and have Errors-To: 1001938032Speter defined in the config file H lines. From J.R. Oldroyd. 1002038032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 1002138032Speter wrong when compiling. Suggested by Rick McCarty of TI. 1002238032Speter Fix a problem that could pass negative SIZE parameter if the 1002338032Speter df file got lost; this would cause servers to always 1002438032Speter give a temporary failure, making the problem even worse. 1002538032Speter Problem noted by Allan Johannesen of WPI. 1002638032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 1002738032Speter protocol timeouts (30s default). Requested by Murray 1002838032Speter Kucherawy of HookUp Communication Corp. to handle bogus 1002938032Speter PC TCP/IP implementations. 1003038032Speter Change $w default definition to be just the first component of 1003138032Speter the domain name on config level 5. The $j macro defaults 1003238032Speter to the FQDN; $m remains as before. This lets well-behaved 1003338032Speter config files use any of the short, long, or subdomain 1003438032Speter names. 1003538032Speter Add makesendmail script in src to try to automate multi-architecture 1003638032Speter builds. I know, this is sub-optimal, but it is still 1003738032Speter helpful. 1003838032Speter Fix very obscure race condition that can cause a queue run to 1003938032Speter get a queue file for an already completed job. This 1004038032Speter problem has existed for years. Problem noted by the 1004138032Speter long suffering Allan Johannesen of WPI. 1004238032Speter Fix a problem that caused the raw sender name to be passed to 1004338032Speter udbsender instead of the canonified name -- this caused 1004438032Speter it to sometimes miss records that it should have found. 1004538032Speter Relax check of name on HELO packet so that a program using -bs 1004638032Speter that claims to be itself works properly. 1004738032Speter Restore rewriting of $: part of address through 2, R, 4 in 1004838032Speter buildaddr -- this requires passing a lot of flags to get 1004938032Speter it right. Unlike old versions, this ONLY rewrites 1005038032Speter recipient addresses, not sender addresses. 1005138032Speter Fix a bug that caused core dumps in config files that cannot 1005238032Speter resolve /file/name style addresses. Fix from Jonathan 1005338032Speter Kamens of OpenVision Technologies. 1005438032Speter Fix problem with fcntl locking that can cause error returns to 1005538032Speter be lost if the lock is lost; this required fully 1005638032Speter queueing everything, dropping the envelope (so errors 1005738032Speter would get returned), and then re-reading the queue from 1005838032Speter scratch. 1005938032Speter Fix a problem that caused aliases that redefine an otherwise 1006038032Speter true address to still send to the original address 1006138032Speter if and only if the alias failed in certain bizarre 1006238032Speter ways (e.g, if they pointed at a list:; syntax address). 1006338032Speter Problem pointed out by Jonathan Kamens. 1006438032Speter Remove support for frozen configuration files. They caused 1006538032Speter more trouble than it was worth. 1006638032Speter Fix problem that can cause error messages to get ignored when 1006738032Speter using both -odb and -t flags. Problem noted by Rob 1006838032Speter McNicholas at U.C. Berkeley. 1006938032Speter Include all "normal" variations on hostname in $=w. For example, 1007038032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 1007138032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 1007238032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 1007338032Speter the queue. 1007438032Speter Reset SmtpPhase global on initial connection creation so that 1007538032Speter messages don't come out with stale information. 1007638032Speter Pass an "ext" argument to lockfile so that error/log messages 1007738032Speter will properly reflect the true filename being locked. 1007838032Speter Put all [...] address forms into $=w -- this eliminates the need 1007938032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 1008038032Speter Myers of CMU. 1008138032Speter Fix a bug that can cause qf files to be left around even after 1008238032Speter an SMTP RSET command. Problem and fix from Michael 1008338032Speter Corrigan. 1008443730Speter Don't send a PostmasterCopy to errors when the Precedence: is 1008538032Speter negative. Error reports still go to the envelope 1008638032Speter sender address. 1008738032Speter Add LA_SHORT for load averages. 1008838032Speter Lock sendmail.st file when posting statistics. 1008938032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 1009038032Speter set the size of the TCP send and receive buffers; if you 1009138032Speter run over a slow slip line you may need to set these down 1009238032Speter (although it would be better to fix the SLIP implementation 1009338032Speter so that it's not necessary to recompile every program 1009438032Speter that does bulk data transfer). 1009538032Speter Allow null defaults on $( ... $) lookups. Problem reported by 1009638032Speter Amir Plivatsky. 1009738032Speter Diagnose crufty S and V config lines. This resulted from an 1009838032Speter observation that some people were using the SITE macro 1009938032Speter without the SITECONFIG macro first, which was causing 1010038032Speter bogus config files that were not caught. 1010138032Speter Fix makemap -f flag to turn off case folding (it was turning it 1010238032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 1010338032Speter Fix a problem that caused multiple error messages to be sent if 1010438032Speter you used "sendmail -t -oem -odb", your system uses fcntl 1010538032Speter locking, and one of the recipient addresses is unknown. 1010638032Speter Reset uid earlier in include() so that recursive .forwards or 1010738032Speter :include:s don't use the wrong uid. 1010838032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 1010938032Speter called, the code to recover the descriptor was broken. 1011038032Speter This sometimes (only sometimes) caused problems with the 1011138032Speter alias file. Fix from Motonori Nakamura. 1011238032Speter Fix a problem that caused aliaswait to go into infinite recursion 1011338032Speter if the @:@ metasymbol wasn't found in the alias file. 1011438032Speter Improve error message on newaliases if database files cannot be 1011538032Speter opened or if running with no database format defined. 1011638032Speter Do a better estimation of the size of error messages when NoReturn 1011738032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 1011838032Speter Fix a problem causing the "c" option (don't connect to expensive 1011938032Speter mailers) to be ignored in SMTP. Problem noted and the 1012038032Speter solution suggested by Robert Elz of The University of 1012138032Speter Melbourne. 1012238032Speter Improve connection caching algorithm by passing "[host]" to 1012338032Speter hostsignature, which strips the square brackets and 1012438032Speter returns the real name. This allows mailertable entries 1012538032Speter to match regular entries. 1012638032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 1012738032Speter feature, even if it doesn't work right. 1012838032Speter Catch and log attempts to try the "wiz" command in server SMTP. 1012938032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 1013038032Speter Be more generous at assigning $z to the home directory -- do this 1013138032Speter for programs that are specified through a .forward file. 1013238032Speter Fix from Andrew Chang of Sun Microsystems. 1013338032Speter Always save a fatal error message in preference to a non-fatal 1013438032Speter error message so that the "subject" line of return 1013538032Speter messages is the best possible. 1013638032Speter CONFIG: reduce the number of quotes needed to quote configuration 1013738032Speter parameters with commas: two quotes should work now, e.g., 1013838032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 1013938032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 1014038032Speter connections (domain-ized UUCP). 1014138032Speter CONFIG: fix bug in default maps (-o must be before database file 1014264562Sgshapiro name). Pointed out by Christophe Wolfhugel. 1014338032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 1014438032Speter DNS. This would presumably be used in UUCP islands. 1014538032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 1014638032Speter CONFIG: log $u in Received: line. This is in technical violation 1014738032Speter of the standards, since it doesn't guarantee a domain 1014838032Speter on the address. 1014938032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 1015038032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 1015138032Speter the "m" flag should you want it. Apparently some Solaris 2.2 1015238032Speter installations can't handle multiple local recipients. 1015338032Speter Problem noted by Josh Smith. 1015438032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 1015538032Speter CONFIG: change default version level from 4 to 5. 1015638032Speter CONFIG: add FEATURE(nullclient) to create a config file that 1015738032Speter forwards all mail to a hub without ever looking at the 1015838032Speter addresses in any detail. 1015938032Speter CONFIG: properly strip mailer: information off of relays when 1016038032Speter used to change .BITNET form into %-hack form. 1016138032Speter CONFIG: fix a problem that caused infinite loops if presented 1016238032Speter with an address such as "!foo". 1016338032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 1016438032Speter the reverse "PTR" mapping is broken. There's a better 1016538032Speter way to do this, but the change is fairly major and I 1016638032Speter want to hold it for another release. Problem noted by 1016738032Speter Bret Marquis. 1016838032Speter 1016964562Sgshapiro8.5/8.5 1993/07/23 1017038032Speter Serious bug: if you used a command line recipient that was unknown 1017138032Speter sendmail would not send a return message (it was treating 1017238032Speter everything as though it had an SMTP-style client that 1017338032Speter would do the return itself). Problem noted by Josh Smith. 1017438032Speter Change "trymx" option in getcanonname() to ignore all MX data, 1017538032Speter even during a T_ANY query. This actually didn't break 1017638032Speter anything, because the only time you called getcanonname 1017738032Speter with !trymx was if you already knew there were no MX 1017838032Speter records, but it is somewhat cleaner. From Motonori 1017938032Speter Nakamura. 1018038032Speter Don't call getcanonname from getmxrr if you already know there 1018138032Speter are no DNS records matching the name. 1018238032Speter Fix a problem causing error messages to always include "The 1018338032Speter original message was received ... from localhost". 1018438032Speter The correct original host information is now included. 1018538032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 1018638032Speter version of "test" doesn't have the -x flag). Change it 1018738032Speter to use -f instead. From John Myers. 1018838032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 1018938032Speter esmtp -- it should be smtp. 1019038032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 1019138032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 1019238032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 1019338032Speter this cleans up the configs somewhat. This fixes a serious 1019438032Speter problem that caused route-addrs to get mistaken as relays, 1019538032Speter pointed out by John Myers. WARNING: this also causes 1019638032Speter the default on SMART_HOST to change from "suucp" to 1019738032Speter "relay" if you have MAILER(smtp) specified. 1019838032Speter 1019964562Sgshapiro8.4/8.4 1993/07/22 1020038032Speter Add option `w'. If you receive a message that comes to you because 1020138032Speter you are the best (lowest preference) target of an MX, and 1020238032Speter you haven't explicitly recognized the source MX host in 1020338032Speter your .cf file, this option will cause you to try the target 1020438032Speter host directly (as if there were no MX for it at all). If 1020538032Speter `w' is not set, this case is a configuration error. 1020638032Speter Beware: if `w' is set, senders may get bogus errors like 1020738032Speter "message timed out" or "host unknown" for problems that 1020838032Speter are really configuration errors. This option is 1020938032Speter disrecommended, provided only for compatibility with 1021038032Speter UIUC sendmail. 1021138032Speter Fix a problem that caused the incoming socket to be left open 1021238032Speter when sendmail forks after the DATA command. This caused 1021338032Speter calling systems to wait in FIN_WAIT_2 state until the 1021438032Speter entire list was processed and the child closed -- a 1021538032Speter potentially prodigious amount of time. Problem noted 1021638032Speter by Neil Rickert. 1021738032Speter Fix problem (created in 6.64) that caused mail sent to multiple 1021838032Speter addresses, one of which was a bad address, to completely 1021938032Speter suppress the sending of the message. This changes 1022038032Speter handling of EF_FATALERRS somewhat, and adds an 1022138032Speter EF_GLOBALERRS flag. This also fixes a potential problem 1022238032Speter with duplicate error messages if there is a syntax error 1022338032Speter in the header of a message that isn't noticed until late 1022438032Speter in processing. Original problem pointed out by Josh Smith 1022538032Speter of Harvey Mudd College. This release includes quite a bit 1022638032Speter of dickering with error handling (see below). 1022738032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 1022838032Speter will only hurt already-broken software and should help 1022938032Speter humans. 1023038032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 1023138032Speter compiled in. It would never read the alias file. 1023238032Speter Repair unbalanced `)' and `>' (the "open" versions are already 1023338032Speter repaired). 1023438032Speter Logging of "done" in dropenvelope() was incorrect: it would 1023538032Speter log this even when the queue file still existed. Change 1023638032Speter this to only log "done" (at log level 11) when the 1023738032Speter queue file is actually removed. From John Myers. 1023838032Speter Log "lost connection" in server SMTP at log level 20 if there 1023938032Speter is no pending transaction. Some senders just close the 1024038032Speter connection rather than sending QUIT. 1024138032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 1024238032Speter domains that do not have MX records -- this would cause 1024338032Speter the subsequent host name lookup to fail. The problem 1024438032Speter only occurred if you had FEATURE(nocanonify) set. 1024538032Speter Problem noted by Rick McCarty of Texas Instruments. 1024638032Speter Fix invocation of setvbuf when passed a -X flag -- I had 1024738032Speter unwittingly used an ANSI C extension, and this caused 1024838032Speter core dumps on some machines. 1024938032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 1025038032Speter Previously it just gave an empty send queue, which 1025138032Speter then gave either "Need RCPT (recipient)" at the DATA 1025238032Speter (confusing, since you had given an RCPT command which 1025338032Speter returned 250) or just dropped the email, depending on 1025438032Speter whether you were running VERBose mode. Now it usually 1025538032Speter diagnoses this case as "aliasing/forwarding loop broken". 1025638032Speter Unfortunately, it still doesn't adequately diagnose 1025738032Speter some true error conditions. 1025838032Speter Add internal concept of "warning messages" using 6xx codes. 1025938032Speter These are not reported only to Postmaster. Unbalanced 1026038032Speter parens, brackets, and quotes are printed as 653 codes. 1026138032Speter They are always mapped to 5xx codes before use in SMTP. 1026238032Speter Clean up error messages to tell both the actual address that 1026338032Speter failed and the alias they arose from. This makes it 1026438032Speter somewhat easier to diagnose problems. Difficulty noted 1026538032Speter by Motonori Nakamura. 1026638032Speter Fix a problem that inappropriately added a ctladdr to addresses 1026738032Speter that shouldn't have had one during a queue run. This 1026838032Speter caused error messages to be handled differently during 1026938032Speter a queue run than a direct run. 1027038032Speter Don't print the qf name and line number if you get errors during 1027138032Speter the direct run of the queue from srvrsmtp -- this was 1027238032Speter just extra stuff for users to crawl through. 1027338032Speter Put command line flags on second line of pid file so you can 1027438032Speter auto-restart the daemon with all appropriate arguments. 1027538032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1027638032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1027738032Speter restart it. 1027838032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1027938032Speter IDENT daemon to screw up. This required that I change 1028038032Speter HASSETEUID to HASSETREUID and complicate the mode 1028138032Speter changing somewhat because both Ultrix and SunOS seem 1028238032Speter to have a bug causing seteuid() to set the saved uid 1028338032Speter as well as the effective. The program test/t_setreuid.c 1028438032Speter will test to see if your implementation of setreuid(2) 1028538032Speter is appropriately functional. 1028638032Speter The FallBackMX (option V) handling failed to properly identify 1028738032Speter fallback to yourself -- most of the code was there, 1028838032Speter but it wasn't being enabled. Problem noted by Murray 1028938032Speter Kucherawy of the University of Waterloo. 1029038032Speter Change :include: open timeout from ETIMEDOUT to an internal 1029138032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1029238032Speter with CurHostName" in error messages, which can be 1029338032Speter confusing. Reported by Jonathan Kamens of OpenVision 1029438032Speter Technologies. 1029538032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1029638032Speter process group id. The original fix was to get around 1029738032Speter some problems with recalcitrant MUAs, but it breaks 1029838032Speter any call from a shell that creates a process group id 1029938032Speter different from the process id. I could try to fix 1030038032Speter this by diddling the tty owner (using tcsetpgrp or 1030138032Speter equivalent) but this is too likely to break other 1030238032Speter things. 1030338032Speter Portability changes: 1030438032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1030538032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1030638032Speter instead of using standard flags. Oh joy. This 1030743730Speter behavior reported by Jon Giltner of University 1030838032Speter of Colorado. 1030938032Speter SGI IRIX -- this includes several changes that should 1031038032Speter help other strict ANSI compilers. 1031138032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1031238032Speter Corporation. 1031338032Speter Solaris running the Sun C compiler (which despite the 1031438032Speter documentation apparently doesn't define 1031538032Speter __STDC__ by default). 1031638032Speter ConvexOS from Eric Schnoebelen of Convex. 1031738032Speter Sony NEWS workstations and Omron LUNA workstations from 1031838032Speter Motonori Nakamura. 1031938032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1032038032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1032138032Speter several people have made a good argument that this 1032238032Speter creates more problems than it solves (although this 1032338032Speter may prove painful in the short run). 1032438032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1032538032Speter format. 1032638032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1032738032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1032838032Speter addresses are also passed through this ruleset. 1032938032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1033038032Speter internet-style addresses would "fall off the end" of 1033138032Speter ruleset zero and be interpreted as local -- however, 1033238032Speter the angle brackets confused the recursive call. 1033338032Speter These are now diagnosed as "Unrecognized host name". 1033438032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1033538032Speter ifdef(`_MAILER_USENET_') instead of 1033638032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1033738032Speter of SINTEF RUNIT, Oslo. 1033838032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1033938032Speter early in ruleset 0; this allows .mc authors to bypass 1034038032Speter things like the "short circuit" code for local addresses. 1034138032Speter Prompted by a comment by Bill Wisner of The Well. 1034238032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1034338032Speter esmtp) to send SMTP mail. This allows you to default 1034438032Speter to esmtp but use a mailertable or other override to 1034538032Speter deal with broken servers. This logic was pointed out 1034638032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1034738032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1034838032Speter environments. Ugly as sin. 1034938032Speter 1035064562Sgshapiro8.3/8.3 1993/07/13 1035138032Speter Fix setuid problems introduced in 8.2 that caused messages 1035238032Speter like "Cannot create qfXXXXXX: Invalid argument" 1035338032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1035438032Speter involved a new compile flag "HASSETEUID" that takes 1035538032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1035638032Speter that the POSIX interface is broken enough to break 1035738032Speter some systems badly. This includes some fixes for 1035838032Speter HP-UX. Also fixes problems where the real uid is 1035938032Speter not reset properly on startup (from Neil Rickert). 1036038032Speter Fix a problem that caused timed out messages to not report the 1036138032Speter addresses that timed out. Error messages are also more 1036238032Speter "user friendly". 1036338032Speter Drop required bandwidth on connections from 64 bytes/sec to 1036438032Speter 16 bytes/sec. 1036538032Speter Further Solaris portability changes -- doesn't require the BSD 1036638032Speter compatibility library. This also adds a new 1036738032Speter "HASGETDTABLESIZE" compile flag which can be used if 1036838032Speter you want to use getdtablesize(2) instead of sysconf(2). 1036938032Speter These are loosely based on changes from David Meyer at 1037038032Speter University of Oregon. This now seems to work, at least 1037138032Speter for quick test cases. 1037238032Speter Fix a problem that can cause duplicate error messages to be 1037338032Speter sent if you are in SMTP, you send to multiple addresses, 1037438032Speter and at least one of those addresses is good and points 1037538032Speter to an account that has a .forward file (whew!). 1037638032Speter Fix a problem causing messages to be discarded if checkcompat() 1037738032Speter returned EX_TEMPFAIL (because it didn't properly mark 1037838032Speter the "to" address). Problem noted by John Myers. 1037938032Speter Fix dfopen to return NULL if the open failed; I was depending 1038038032Speter on fdopen(-1) returning NULL, which isn't the case. This 1038138032Speter isn't serious, but does result in weird error diagnoses. 1038238032Speter From Michael Corrigan. 1038338032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1038438032Speter messages sent through UUCP-family mailers. Suggested 1038538032Speter by Bill Wisner of The Well. 1038638032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1038738032Speter include a "uucp-dom" mailer that uses domain-style 1038838032Speter addressing. Suggested by Bill Wisner. 1038938032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1039038032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1039138032Speter Christophe Wolfhugel. 1039238032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1039338032Speter 1039464562Sgshapiro8.2/8.2 1993/07/11 1039538032Speter Don't drop out on config file parse errors in -bt mode. 1039638032Speter On older configuration files, assume option "l" (use Errors-To 1039738032Speter header) for back compatibility. NOTE: this DOES NOT 1039838032Speter imply an endorsement of the Errors-To: header in any way. 1039938032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1040038032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1040138032Speter SMTP server to give an error on this command, and 1040238032Speter logging it in the transcript can be confusing. Fix 1040338032Speter from Bill Wisner. 1040438032Speter IRIX compatibility changes provided by Dan Rich 1040538032Speter <drich@sandman.lerc.nasa.gov>. 1040638032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1040738032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1040838032Speter <juo@klinzhai.rutgers.edu> 1040938032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1041038032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1041138032Speter match the other flags in that file. 1041238032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1041338032Speter Save h_errno in mci struct and improve error message display. 1041438032Speter Changes from Eric Wassenaar. 1041538032Speter Open /dev/null for the transcript if the create of the xf file 1041638032Speter failed; this avoids at least one possible null pointer 1041738032Speter reference in very weird cases. From Eric Wassenaar. 1041838032Speter Clean up statistics gathering; it was over-reporting because of 1041938032Speter forks. From Eric Wassenaar. 1042038032Speter Fix problem that causes old Return-Path: line to override new 1042138032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1042238032Speter re-using old value). From Motonori Nakamura. 1042338032Speter Fix broken -m flag in K definition -- even if -m (match only) 1042438032Speter was specified, it would still replace the key with the 1042538032Speter value. Noted by Rick McCarty of Texas Instruments. 1042638032Speter If the name server timed out over several days, no "timed out" 1042738032Speter message would ever be sent back. The timeout code 1042838032Speter has been moved from markfailure() to dropenvelope() 1042938032Speter so that all such failures should be diagnosed. Pointed 1043038032Speter out by Christophe Wolfhugel and others. 1043138032Speter Relax safefile() constraints: directories in an include or 1043238032Speter forward path must be readable by self if the controlling 1043338032Speter user owns the entry, readable by all otherwise (e.g., 1043438032Speter when reading your .forward file, you have to own and 1043538032Speter have X permission in it; everyone needs X permission in 1043638032Speter the root and directories leading up to your home); 1043738032Speter include files must be readable by anyone, but need not 1043838032Speter be owned by you. 1043938032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1044038032Speter reading a .forward file; this gets around some problems 1044138032Speter on NFS mounts if root permission is not exported and 1044238032Speter the user's home directory isn't x'able. 1044338032Speter Additional NeXT portability enhancements from Axel Zinser. 1044438032Speter Additional HP-UX portability enhancements from Brian Bullen. 1044538032Speter Add a timeout around SMTP message writes; this assumes you can 1044638032Speter get throughput of at least 64 bytes/second. Note that 1044738032Speter this does not impact the "datafinal" default, which 1044838032Speter is separate; this is just intended to work around 1044938032Speter network clogs that will occur before the final dot 1045038032Speter is sent. From Eric Wassenaar. 1045138032Speter Change map code to set the "include null" flag adaptively -- 1045238032Speter it initially tries both, but if it finds anything 1045338032Speter matching without a null it never tries again with a 1045438032Speter null and vice versa. If -N is specified, it never 1045538032Speter tries without the null and creates new maps with a 1045638032Speter null byte. If -O is specified, it never tries with 1045738032Speter the null (for efficiency). If -N and -O are specified, 1045838032Speter you get -NO (get it?) lookup at all, so this would 1045938032Speter be a bad idea. If you don't specify either -N or -O, 1046038032Speter it adapts. 1046138032Speter Fix recognition of "same from address" so that MH submissions 1046238032Speter will insert the appropriate full name information; 1046338032Speter this used to work and got broken somewhere along the 1046438032Speter way. 1046538032Speter Some changes to eliminate some unnecessary SYSERRs in the 1046638032Speter log. For example, if you lost a connection, don't 1046738032Speter bother reporting that fact on the connection you lost. 1046838032Speter Add some "extended debugging" flags to try to track down 1046938032Speter why we get occasional problems with file descriptor 1047038032Speter one being closed when execing a mailer; it seems to 1047138032Speter only happen when there has been another error in the 1047238032Speter same transaction. This requires XDEBUG, defined 1047338032Speter by default in conf.h. 1047438032Speter Add "-X filename" command line flag, which logs both sides of 1047538032Speter all SMTP transactions. This is intended ONLY for 1047638032Speter debugging bad implementations of other mailers; start 1047738032Speter it up, send a message from a mailer that is failing, 1047838032Speter and then kill it off and examine the indicated log. 1047938032Speter This output is not intended to be particularly human 1048038032Speter readable. This also adds the HASSETVBUF compile 1048138032Speter flag, defaulted on if your compiler defines __STDC__. 1048238032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1048338032Speter have a local net that should get direct connects, you 1048438032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1048538032Speter See cf/README for an example. 1048638032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1048738032Speter sites that don't use the -d flag. 1048838032Speter CONFIG: hide recipient addresses as well as sender addresses 1048938032Speter behind $M if FEATURE(allmasquerade) is specified; this 1049038032Speter has been requested by several people, but can break 1049138032Speter local aliases. For example, if you mail to "localalias" 1049238032Speter this will be rewritten as "localalias@masqueradehost"; 1049338032Speter although initial delivery will work, replies will be 1049438032Speter broken. Use it sparingly. 1049538032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1049638032Speter to qualified domains in headers. I believe this is 1049738032Speter largely equivalent to the IDA feature of the same name. 1049838032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1049938032Speter to override the "system name" as your UUCP name -- 1050038032Speter in particular, to use domain-ized UUCP names. From 1050138032Speter Bill Wisner of The Well. 1050238032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1050338032Speter first. This is currently unused in the config files, 1050438032Speter but could be used in a mailertable entry. 1050538032Speter 1050664562Sgshapiro8.1C/8.1B 1993/06/27 1050738032Speter Serious security bug fix: it was possible to read any file on 1050838032Speter the system, regardless of ownership and permissions. 1050938032Speter If a subroutine returns a fully qualified address, return it 1051038032Speter immediately instead of feeding it back into rewriting. 1051138032Speter This fixes a problem with mailertable lookups. 1051238032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1051338032Speter 1051464562Sgshapiro8.1B/8.1A 1993/06/12 1051538032Speter Serious bug fix: pattern matching backup algorithm stepped by 1051638032Speter two tokens in classes instead of one. Found by Claus 1051738032Speter Assmann at University of Kiel, Germany. 1051838032Speter 1051964562Sgshapiro8.1A/8.1A 1993/06/08 1052038032Speter Another mailertable fix.... 1052138032Speter 1052264562Sgshapiro8.1/8.1 1993/06/07 1052338032Speter 4.4BSD freeze.
