138032Speter SENDMAIL RELEASE NOTES 2244833Sgshapiro $Id: RELEASE_NOTES,v 8.2011 2012/12/21 18:42:16 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 9244833Sgshapiro8.14.6/8.14.6 2012/12/23 10244833Sgshapiro Fix a regression introduced in 8.14.5: if a server offers 11244833Sgshapiro two AUTH lines, the MTA would not read them after 12244833Sgshapiro STARTTLS has been used and hence SMTP AUTH for 13244833Sgshapiro the client side would fail. Problem noted by Lena. 14244833Sgshapiro Do not cache hostnames internally in a non case sensitive way 15244833Sgshapiro as that may cause addresses to change from lower case 16244833Sgshapiro to upper case or vice versa. These header modifications 17244833Sgshapiro can cause problems with milters that rely on receiving 18244833Sgshapiro headers in the same way as they are being sent out such 19244833Sgshapiro as a DKIM signing milter. 20244833Sgshapiro If MaxQueueChildren is set then it was possible that new queue 21244833Sgshapiro runners could not be started anymore because an 22244833Sgshapiro internal counter was subject to a race condition. 23244833Sgshapiro If a milter decreases the timeout it waits for a communication 24244833Sgshapiro with the MTA, the MTA might experience a write() timeout. 25244833Sgshapiro In some situations, the resulting error might have been 26244833Sgshapiro ignored. Problem noted by Werner Wiethege. 27244833Sgshapiro Note: decreasing the communication timeout in a milter 28244833Sgshapiro should not be done without considering the potential 29244833Sgshapiro problems. 30244833Sgshapiro smfi_setsymlist() now properly sets the list of macros for 31244833Sgshapiro the milter which invoked it, instead of a global 32244833Sgshapiro list for all milters. Problem reported by 33244833Sgshapiro David Shrimpton of the University of Queensland. 34244833Sgshapiro If Timeout.resolver.retrans is set to a value larger than 20, 35244833Sgshapiro then resolver.retry was temporarily set to 0 for 36244833Sgshapiro gethostbyaddr() lookups. Now it is set to 1 instead. 37244833Sgshapiro Patch from Peter. 38244833Sgshapiro If sendmail could not lock the statistics file due to a system 39244833Sgshapiro error, and sendmail later sends a DSN for a mail that 40244833Sgshapiro triggered such an error, then sendmail tried to access 41244833Sgshapiro memory that was freed before (causing a crash on some 42244833Sgshapiro systems). Problem reported by Ryan Stone. 43244833Sgshapiro Do not log negative values for size= nor pri= to avoid confusing 44244833Sgshapiro log parsers, instead limit the values to LONG_MAX. 45244833Sgshapiro Account for an API change in newer versions of Cyrus-SASL. 46244833Sgshapiro Patch from Hajimu UMEMOTO from FreeBSD. 47244833Sgshapiro Do not try to resolve link-local addresses for IPv4 (just as it 48244833Sgshapiro is done for IPv6). Patch from John Beck of Oracle. 49244833Sgshapiro Improve logging of client and server STARTTLS connection failures 50244833Sgshapiro that may be due to incompatible cipher lists by including 51244833Sgshapiro the reason for the failure in a single log line. Suggested 52244833Sgshapiro by James Carey of Boeing. 53244833Sgshapiro Portability: 54244833Sgshapiro Add support for Darwin 11.x and 12.x (Mac OS X 10.7 and 10.8). 55244833Sgshapiro Add support for SunOS 5.12 (aka Solaris 12). Patch from 56244833Sgshapiro John Beck of Oracle. 57244833Sgshapiro 58223067Sgshapiro8.14.5/8.14.5 2011/05/17 59223067Sgshapiro Do not cache SMTP extensions across connections as the cache 60223067Sgshapiro is based on hostname which may not be a unique identifier 61223067Sgshapiro for a server, i.e., different machines may have the 62223067Sgshapiro same hostname but provide different SMTP extensions. 63223067Sgshapiro Problem noted by Jim Hermann. 64223067Sgshapiro Avoid an out-of-bounds access in case a resolver reply for a DNS 65223067Sgshapiro map lookup returns a size larger than 1K. Based on a 66223067Sgshapiro patch from Dr. Werner Fink of SuSE. 67223067Sgshapiro If a job is aborted using the interrupt signal (e.g., control-C from 68223067Sgshapiro the keyboard), perform minimal cleanup to avoid invoking 69223067Sgshapiro functions that are not signal-safe. Note: in previous 70223067Sgshapiro versions the mail might have been queued up already 71223067Sgshapiro and would be delivered subsequently, now an interrupt 72223067Sgshapiro will always remove the queue files and thus prevent 73223067Sgshapiro delivery. 74223067Sgshapiro Per RFC 6176, when operating as a TLS client, do not offer SSLv2. 75223067Sgshapiro Since TLS session resumption is never used as a client, disable 76223067Sgshapiro use of RFC 4507-style session tickets. 77223067Sgshapiro Work around gcc4 versions which reverse 25 years of history and 78223067Sgshapiro no longer align char buffers on the stack, breaking calls 79223067Sgshapiro to resolver functions on strict alignment platforms. 80223067Sgshapiro Found by Stuart Henderson of OpenBSD. 81223067Sgshapiro Read at most two AUTH lines from a server greeting (up to two 82223067Sgshapiro lines are read because servers may use "AUTH mechs" and 83223067Sgshapiro "AUTH=mechs"). Otherwise a malicious server may exhaust 84223067Sgshapiro the memory of the client. Bug report by Nils of MWR 85223067Sgshapiro InfoSecurity. 86223067Sgshapiro Avoid triggering an assertion in the OpenLDAP code when the 87223067Sgshapiro connection to an LDAP server is lost while making a query. 88223067Sgshapiro Problem noted and patch provided by Andy Fiddaman. 89223067Sgshapiro If ConnectOnlyTo is set and sendmail is compiled with NETINET6 90223067Sgshapiro it would try to use an IPv6 address if an IPv4 (or 91223067Sgshapiro unparseable) address is specified. 92223067Sgshapiro If SASLv2 is used, make sure that the macro {auth_authen} is 93223067Sgshapiro stored in xtext format to avoid problems with parsing 94223067Sgshapiro it. Problem noted by Christophe Wolfhugel. 95223067Sgshapiro CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing 96223067Sgshapiro -T<TMPF> that is required, but failed for some cases 97223067Sgshapiro that did not use LDAP. This change has been undone 98223067Sgshapiro until a better solution can be implemented. Problem 99223067Sgshapiro found by Andy Fiddaman. 100223067Sgshapiro CONFIG: Add cf/ostype/solaris11.m4 for Solaris11 support. 101223067Sgshapiro Contributed by Casper Dik of Oracle. 102223067Sgshapiro CONTRIB: qtool.pl: Deal with H entries that do not have a 103223067Sgshapiro letter between the question marks. Patch from 104223067Sgshapiro Stefan Christensen. 105223067Sgshapiro DOC: Use a better description for the -i option in sendmail. 106223067Sgshapiro Patch from Mitchell Berger. 107223067Sgshapiro Portability: 108223067Sgshapiro Add support for Darwin 10.x (Mac OS X 10.6). 109223067Sgshapiro Enable HAVE_NANOSLEEP for FreeBSD 3 and later. Patch 110223067Sgshapiro from John Marshall. 111223067Sgshapiro Enable HAVE_NANOSLEEP for OpenBSD 4.3 and later. 112223067Sgshapiro Use new directory "/system/volatile" for PidFile on 113223067Sgshapiro Solaris 11. Patch from Casper Dik of Oracle. 114223067Sgshapiro Fix compilation on Solaris 11 (and maybe some other 115223067Sgshapiro OSs) when using OpenSSL 1.0. Based on patch from 116223067Sgshapiro Jan Pechanec of Oracle. 117223067Sgshapiro Set SOCKADDR_LEN_T and SOCKOPT_LEN_T to socklen_t 118223067Sgshapiro for Solaris 11. Patch from Roger Faulkner of Oracle. 119223067Sgshapiro New Files: 120223067Sgshapiro cf/ostype/solaris11.m4 121223067Sgshapiro 122203004Sgshapiro8.14.4/8.14.4 2009/12/30 123203004Sgshapiro SECURITY: Handle bogus certificates containing NUL characters 124203004Sgshapiro in CNs by placing a string indicating a bad certificate 125203004Sgshapiro in the {cn_subject} or {cn_issuer} macro. Patch inspired 126203004Sgshapiro by Matthias Andree's changes for fetchmail. 127203004Sgshapiro During the generation of a queue identifier an integer overflow 128203004Sgshapiro could occur which might result in bogus characters 129203004Sgshapiro being used. Based on patch from John Vannoy of 130203004Sgshapiro Pepperdine University. 131203004Sgshapiro The value of headers, e.g., Precedence, Content-Type, et.al., 132203004Sgshapiro was not processed correctly. Patch from Per Hedeland. 133203004Sgshapiro Between 8.11.7 and 8.12.0 the length limitation on a return 134203004Sgshapiro path was erroneously reduced from MAXNAME (256) to 135203004Sgshapiro MAXSHORTSTR (203). Patch from John Gardiner Myers 136203004Sgshapiro of Proofpoint; the problem was also noted by Steve 137203004Sgshapiro Hubert of University of Washington. 138203004Sgshapiro Prevent a crash when a hostname lookup returns a seemingly 139203004Sgshapiro valid result which contains a NULL pointer (this seems 140203004Sgshapiro to be happening on some Linux versions). 141203004Sgshapiro The process title was missing the current load average when 142203004Sgshapiro the MTA was delaying connections due to DelayLA. 143203004Sgshapiro Patch from Dick St.Peters of NetHeaven. 144203004Sgshapiro Do not reset the number of queue entries in shared memory if 145203004Sgshapiro only some of them are processed. 146203004Sgshapiro Fix overflow of an internal array when parsing some replies 147203004Sgshapiro from a milter. Problem found by Scott Rotondo 148203004Sgshapiro of Sun Microsystems. 149203004Sgshapiro If STARTTLS is turned off in the server (via M=S) then it 150203004Sgshapiro would not be initialized for use in the client either. 151203004Sgshapiro Patch from Kazuteru Okahashi of IIJ. 152203004Sgshapiro If a Diffie-Hellman cipher is selected for STARTTLS, the 153203004Sgshapiro handshake could fail with some TLS implementations 154203004Sgshapiro because the prime used by the server is not long enough. 155203004Sgshapiro Note: the initialization of the DSA/DH parameters for 156203004Sgshapiro the server can take a significant amount of time on slow 157203004Sgshapiro machines. This can be turned off by setting DHParameters 158203004Sgshapiro to none or a file (see doc/op/op.me). Patch from 159203004Sgshapiro Petr Lampa of the Brno University of Technology. 160203004Sgshapiro Fix handling of `b' modifier for DaemonPortOptions on little 161203004Sgshapiro endian machines for loopback address. Patch from 162203004Sgshapiro John Beck of Sun Microsystems. 163203004Sgshapiro Fix a potential memory leak in libsmdb/smdb1.c found by parfait. 164203004Sgshapiro Based on patch from Jonathan Gray of OpenBSD. 165203004Sgshapiro If a milter sets the reply code to "421" during the transfer 166203004Sgshapiro of the body, the SMTP server will terminate the SMTP session 167203004Sgshapiro with that error to match the behavior of the other callbacks. 168203004Sgshapiro Return EX_IOERR (instead of 0) if a mail submission fails due to 169203004Sgshapiro missing disk space in the mail queue. Based on patch 170203004Sgshapiro from Martin Poole of RedHat. 171203004Sgshapiro CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would 172203004Sgshapiro cause addresses not found in LDAP to be misparsed. 173203004Sgshapiro CONFIG: Using a CN restriction did not work for TLS_Clt as it 174203004Sgshapiro referred to a wrong macro. Patch from John Gardiner 175203004Sgshapiro Myers of Proofpoint. 176203004Sgshapiro CONFIG: The option relaytofulladdress of FEATURE(`access_db') 177203004Sgshapiro did not work if FEATURE(`relay_hosts_only') is used too. 178203004Sgshapiro Problem noted by Kristian Shaw. 179203004Sgshapiro CONFIG: The internal function lower() was broken and hence 180203004Sgshapiro strcasecmp() did not work either, which could cause 181203004Sgshapiro problems for some FEATURE()s if upper case arguments 182203004Sgshapiro were used. Patch from Vesa-Matti J Kari of the 183203004Sgshapiro University of Helsinki. 184203004Sgshapiro LIBMILTER: Fix internal check whether a milter application 185203004Sgshapiro is compiled against the same version of libmilter as 186203004Sgshapiro it is linked against (especially useful for dynamic 187203004Sgshapiro libraries). 188203004Sgshapiro LIBMILTER: Fix memory leak that occurred when smfi_setsymlist() 189203004Sgshapiro was used. Based on patch by Dan Lukes. 190203004Sgshapiro LIBMILTER: Document the effect of SMFIP_HDR_LEADSPC for filters 191203004Sgshapiro which add, insert, or replace headers. From Benjamin 192203004Sgshapiro Pineau. 193203004Sgshapiro LIBMILTER: Fix error messages which refer to "select()" to be 194203004Sgshapiro correct if SM_CONF_POLL is used. Based on patch from 195203004Sgshapiro John Nemeth. 196203004Sgshapiro LIBSM: Fix handling of LDAP search failures where the error is 197203004Sgshapiro carried in the search result itself, such as seen with 198203004Sgshapiro OpenLDAP proxy servers. 199203004Sgshapiro VACATION: Do not refer to a local variable outside its scope. 200203004Sgshapiro Based on patch from Mark Costlow of Southwest Cyberport. 201203004Sgshapiro Portability: 202203004Sgshapiro Enable HAVE_NANOSLEEP for SunOS 5.11. Patch from 203203004Sgshapiro John Beck of Sun Microsystems. 204203004Sgshapiro Drop NISPLUS from default SunOS 5.11 map definitions. 205203004Sgshapiro Patch from John Beck of Sun Microsystems. 206203004Sgshapiro 207182352Sgshapiro8.14.3/8.14.3 2008/05/03 208182352Sgshapiro During ruleset processing the generation of a key for a map 209182352Sgshapiro lookup and the parsing of the default value was broken 210182352Sgshapiro for some macros, e.g., $|, which caused the BlankSub 211182352Sgshapiro character to be inserted into the workspace and thus 212182352Sgshapiro failures, e.g., rules that should have matched did not. 213182352Sgshapiro 8.14.2 caused a regression: it accessed (macro) storage which was 214182352Sgshapiro freed before. First instance of the problem reported by 215182352Sgshapiro Matthew Dillon of DragonFlyBSD; variations of the same 216182352Sgshapiro bug reported by Todd C. Miller of OpenBSD, Moritz 217182352Sgshapiro Jodeit, and Dave Hayes. 218182352Sgshapiro Improve pathname length checks for persistent host status. Patch 219182352Sgshapiro from Joerg Sonnenberger of DragonFlyBSD. 220182352Sgshapiro Reword misleading SMTP reply text for FEATURE(`badmx'). Problem 221182352Sgshapiro noted by Beth Halsema. 222182352Sgshapiro The read timeout was fixed to be Timeout.datablock if STARTTLS 223182352Sgshapiro was activated. This may cause problems if that value 224182352Sgshapiro is lowered from its default. Problem noted by Jens Elkner. 225182352Sgshapiro CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset 226182352Sgshapiro to operate incorrectly. Problem found by Werner Wiethege. 227182352Sgshapiro LIBMILTER: Omitting some protocol steps via the xxfi_negotiate() 228182352Sgshapiro callback did not work properly. The patchlevel of 229182352Sgshapiro libmilter has been set to 1 so a milter can determine 230182352Sgshapiro whether libmilter contains this fix. 231182352Sgshapiro MAKEMAP: If a delimiter is specified (-t) use that also when 232182352Sgshapiro dumping a map. Patch from Todd C. Miller of OpenBSD. 233182352Sgshapiro Portability: 234182352Sgshapiro Add support for Darwin 9.x (Mac OS X 10.5). 235182352Sgshapiro Support shared libraries in Darwin 8 and 9. Patch from 236182352Sgshapiro Chris Behrens of Concentric. 237182352Sgshapiro Add support for SCO OpenServer 6, patch from Boyd Gerber. 238203004Sgshapiro DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing slash. 239182352Sgshapiro Added Files: 240182352Sgshapiro devtools/OS/Darwin.9.x 241182352Sgshapiro devtools/OS/OSR.i386 242182352Sgshapiro 243173340Sgshapiro8.14.2/8.14.2 2007/11/01 244173340Sgshapiro If a message was queued and it contained 8 bit characters in 245173340Sgshapiro a From: or To: header, then those characters could be 246173340Sgshapiro "mistaken" for internal control characters during a queue 247173340Sgshapiro run and trigger various consistency checks. Problem 248173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 249173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 250173340Sgshapiro it is by default) then even if the Linelimit parameter 251173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 252173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 253173340Sgshapiro Myers of Proofpoint. 254173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 255173340Sgshapiro work in earlier 8.14 versions. 256173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 257173340Sgshapiro background if a milter can reject or delete a recipient. 258173340Sgshapiro Prior to 8.14 this happened only if milter could delete 259173340Sgshapiro recipients. 260173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 261182352Sgshapiro documented), not when it was reached. Patch from 262173340Sgshapiro John Beck of Sun Microsystems. 263173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 264173340Sgshapiro specified (R=0) and forking (F=f) is requested. 265173340Sgshapiro When multiple results are requested for a DNS map lookup 266173340Sgshapiro (-z and -Z), return only those that are relevant for 267173340Sgshapiro the query (not also those in the "additional section".) 268173340Sgshapiro If the message transfer time to sendmail (when acting as server) 269173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 270173340Sgshapiro the message is refused (by a milter), sendmail previously 271173340Sgshapiro created a delivery status notification (DSN). Patch 272173340Sgshapiro from Doug Heath of The Hertz Corporation. 273173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 274173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 275173340Sgshapiro Problem noted by Eliot Lear. 276173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 277173340Sgshapiro compiled in but not offered by the server and the 278173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 279173340Sgshapiro If getting the result of an LDAP query times out then close the 280173340Sgshapiro map so it will be reopened on the next lookup. This 281173340Sgshapiro should help "failover" configurations that specify more 282173340Sgshapiro than one LDAP server. 283173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 284173340Sgshapiro be triggered under some circumstances (e.g., requiring 285173340Sgshapiro a system which does not have the compile time flag 286173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 287173340Sgshapiro of National Institute of Informatics, Japan. 288173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 289173340Sgshapiro logfile entry might have been wrong. Problem found by 290173340Sgshapiro Petra Humann of TU Dresden. 291173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 292173340Sgshapiro NULL, the message body was lost. Patch from Motonori 293173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 294173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 295173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 296173340Sgshapiro replacing files. 297173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 298173340Sgshapiro reading the /etc/mail/virtusers/ directory. 299173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 300173340Sgshapiro appropriate. 301173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 302173340Sgshapiro against an older libmilter.so shared library can use an 303173340Sgshapiro 8.14 libmilter.so shared library. 304173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 305173340Sgshapiro from the version number, however, the returned value was 306173340Sgshapiro correct for the current libmilter version. 307173340Sgshapiro 308168515Sgshapiro8.14.1/8.14.1 2007/04/03 309168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 310168515Sgshapiro it in its list of recipients and deliver to it if the 311168515Sgshapiro transaction is accepted. This is a regression introduced 312168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 313168515Sgshapiro found by Andy Fiddaman. 314168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 315168515Sgshapiro could not be set in 8.14.0. 316168515Sgshapiro If a server shut down the connection in response to a STARTTLS 317168515Sgshapiro command, sendmail would log a misleading error message 318168515Sgshapiro due to an internal inconsistency. Problem found by 319168515Sgshapiro Werner Wiethege. 320168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 321168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 322168515Sgshapiro Science and Mathematics. 323168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 324168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 325168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 326168515Sgshapiro m4 options for setting MaxNOOPCommands and 327168515Sgshapiro SharedMemoryKeyFile. 328168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 329168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 330168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 331168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 332168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 333168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 334168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 335168515Sgshapiro negotiation. Problem reported by Bryan Costales. 336168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 337168515Sgshapiro Patches from Bryan Costales. 338168515Sgshapiro PORTABILITY FIXES: 339168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 340168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 341168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 342168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 343168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 344168515Sgshapiro Software Systems. 345168515Sgshapiro New Files: 346168515Sgshapiro devtools/M4/depend/QNX6.m4 347168515Sgshapiro devtools/OS/QNX.6.x 348168515Sgshapiro include/sm/os/sm_os_qnx.h 349168515Sgshapiro 350168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 351168515Sgshapiro libmilter/docs/smfi_chgfrom.html 352168515Sgshapiro libmilter/docs/smfi_version.html 353168515Sgshapiro 354168515Sgshapiro8.14.0/8.14.0 2007/01/31 355168515Sgshapiro Header field values are now 8 bit clean. Notes: 356168515Sgshapiro - header field names are still restricted to 7 bit. 357168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 358168515Sgshapiro headers. 359168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 360168515Sgshapiro number of spaces after the colon would be changed to 361168515Sgshapiro exactly one space. 362168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 363168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 364168515Sgshapiro limit may be reached too early, e.g., the counter 365168515Sgshapiro may be off by a factor of 4 in case of a sequence of 366168515Sgshapiro .forward files that refer to others. Patch from 367168515Sgshapiro Motonori Nakamura of Kyoto University. 368168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 369168515Sgshapiro "sendmail -bs" can trigger an assertion because the 370168515Sgshapiro hostname of the client is undefined. It is now set 371168515Sgshapiro to "localhost" for the xxfi_connect() callback. 372168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 373168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 374168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 375168515Sgshapiro Patch from Nik Clayton. 376168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 377168515Sgshapiro permanent errors (5xy). This can be useful for testing. 378168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 379168515Sgshapiro per daemon socket: 380168515Sgshapiro DeliveryMode DeliveryMode 381168515Sgshapiro refuseLA RefuseLA 382168515Sgshapiro delayLA DelayLA 383168515Sgshapiro queueLA QueueLA 384168515Sgshapiro children MaxDaemonChildren 385168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 386168515Sgshapiro lookup key with the LDAP escaped contents of the 387168515Sgshapiro arguments specified in the map lookup. Loosely based 388168515Sgshapiro on patch from Wolfgang Hottgenroth. 389168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 390168515Sgshapiro from Nik Clayton. 391168515Sgshapiro If a client is rejected via TCP wrapper or some other check 392168515Sgshapiro performed by validate_connection() (in conf.c) then do 393168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 394168515Sgshapiro of the University of Illinois at Urbana-Champaign. 395168515Sgshapiro If a client terminates the SMTP connection during a pause 396168515Sgshapiro introduced by greet_pause, then a misleading message 397168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 398168515Sgshapiro et.al., patch from Matej Vela. 399168515Sgshapiro New command "mstat" for control socket to provide "machine 400168515Sgshapiro readable" status. 401168515Sgshapiro New named config file rule check_eom which is called at the end 402168515Sgshapiro of a message, its parameter is the size of the message. 403168515Sgshapiro If the macro {addr_type} indicates that the current address 404168515Sgshapiro is a header address it also distinguishes between 405168515Sgshapiro recipient and sender addresses (as it is done for 406168515Sgshapiro envelope addresses). 407168515Sgshapiro When a macro is set in check_relay, then its value is accessible 408168515Sgshapiro by all transactions in the same SMTP session. 409168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 410168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 411168515Sgshapiro number of "useless" commands before the SMTP server will 412168515Sgshapiro slow down responding. 413168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 414168515Sgshapiro enabled, the MTA can be asked to select a shared memory 415168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 416168515Sgshapiro a file where to store the selected key. 417168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 418168515Sgshapiro by recognizing some commands from them. If the first command 419168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 420168515Sgshapiro connection is terminated immediately. 421168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 422168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 423168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 424168515Sgshapiro New options B, z, and Z for DNS maps: 425168515Sgshapiro -B: specify a domain that is always appended to queries. 426168515Sgshapiro -z: specify the delimiter at which to cut off the result of 427168515Sgshapiro a query if it is too long. 428168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 429168515Sgshapiro to form the result of a lookup. 430168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 431168515Sgshapiro implicitly while building libsm, they must be explicitly 432168515Sgshapiro started by using "make check". 433168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 434168515Sgshapiro reported by the SATURN tool which has been developed by 435168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 436168515Sgshapiro Fix a potential race condition caused by a signal handler for 437168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 438168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 439168515Sgshapiro queue group selection. This has been disabled as it was not 440168515Sgshapiro intended. 441168515Sgshapiro New operator 'r' for the arith map to return a random number. 442168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 443168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 444168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 445168515Sgshapiro which may improve the communication performance on some 446168515Sgshapiro operating systems. Patch from John Gardiner Myers of 447168515Sgshapiro Proofpoint. 448168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 449168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 450168515Sgshapiro generate an additional blank line in the output as the last 451168515Sgshapiro line. 452168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 453168515Sgshapiro the "queue control process" (QCP) works now. 454168515Sgshapiro Increase the length of an input line to 12288 to deal with 455168515Sgshapiro really long lines during SMTP AUTH negotiations. 456168515Sgshapiro Problem noted by Werner Wiethege. 457168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 458168515Sgshapiro a missing initialization call for that case). Problem 459168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 460168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 461168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 462168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 463168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 464168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 465168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 466168515Sgshapiro the MTA will not attempt to open a statistics file on 467168515Sgshapiro each delivery. 468168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 469168515Sgshapiro clients whose IP address does not have proper reverse DNS. 470168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 471168515Sgshapiro and John Beck of Sun Microsystems. 472168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 473168515Sgshapiro clients which provide a HELO/EHLO argument which is either 474168515Sgshapiro unqualified, or is one of our own names (i.e., the server 475168515Sgshapiro name instead of the client name). Contributed by Neil 476168515Sgshapiro Rickert of Northern Illinois University and John Beck of 477168515Sgshapiro Sun Microsystems. 478168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 479168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 480168515Sgshapiro Based on contribution from William Dell Wisner. 481168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 482168515Sgshapiro the maximum line length of the smtp mailers. 483168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 484168515Sgshapiro to allow entries in the access map to be of the form 485168515Sgshapiro To:user@example.com RELAY 486168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 487168515Sgshapiro macros a milter should receive at those stages in the 488168515Sgshapiro SMTP dialogue. 489168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 490168515Sgshapiro for the HELO/EHLO command. 491168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 492168515Sgshapiro messages by using those values as second argument. 493168515Sgshapiro Patches from Nelson Fung. 494168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 495168515Sgshapiro ignores everything after it unless it is in quotes or 496168515Sgshapiro preceeded by a backslash. 497168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 498168515Sgshapiro directories, then it used for "make install" to create 499168515Sgshapiro the required installation directories. 500168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 501168515Sgshapiro executables (defaults to confCC). 502168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 503168515Sgshapiro has several changes which are listed below and documented 504168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 505168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 506168515Sgshapiro changed. It now refers only to the version of libmilter, 507168515Sgshapiro not to the protocol version (which is used only internally, 508168515Sgshapiro it is not user/milter-programmer visible). Additionally, 509168515Sgshapiro a version function smfi_version() has been introduced such 510168515Sgshapiro that a milter program can check the libmilter version also 511168515Sgshapiro at runtime which is useful if a shared library is used. 512168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 513168515Sgshapiro dynamically (i.e., at runtime) determine the available 514168515Sgshapiro protocol actions and features of the MTA and also to 515168515Sgshapiro specify which of these a milter wants to use. This allows 516168515Sgshapiro for more flexibility than hardcoding these flags in the 517168515Sgshapiro xxfi_flags field of the smfiDesc structure. 518168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 519168515Sgshapiro can act on the DATA command. 520168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 521168515Sgshapiro can receive also unknown SMTP commands. 522168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 523168515Sgshapiro can be used by the xxfi_header() callback provided the 524168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 525168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 526168515Sgshapiro xxfi_body() callback to skip over further body chunks 527168515Sgshapiro and directly advance to the xxfi_eom() callback. This 528168515Sgshapiro is useful if a milter can make a decision based on the 529168515Sgshapiro body chunks it already received without reading the entire 530168515Sgshapiro rest of the body and the milter wants to invoke functions 531168515Sgshapiro that are only available from the xxfi_eom() callback. 532168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 533168515Sgshapiro new recipients including ESMTP parameters. 534168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 535168515Sgshapiro envelope sender including ESMTP parameters. 536168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 537168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 538168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 539168515Sgshapiro a RCPT has been rejected can be checked by comparing the 540168515Sgshapiro value of the macro {rcpt_mailer} with "error". 541168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 542168515Sgshapiro wants to receive from the MTA for each protocol step 543168515Sgshapiro by invoking the function smfi_setsymlist() during option 544168515Sgshapiro negotiation. 545168515Sgshapiro LIBMILTER: A milter can receive header field values with all 546168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 547168515Sgshapiro protocol action. Also, if the flag is set then the MTA 548168515Sgshapiro does not add a leading space to headers that are added, 549168515Sgshapiro inserted, or replaced. 550168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 551168515Sgshapiro callback, the SMTP server will terminate the SMTP session 552168515Sgshapiro with that error to match the behavior of all other callbacks. 553168515Sgshapiro New Files: 554168515Sgshapiro cf/feature/badmx.m4 555168515Sgshapiro cf/feature/block_bad_helo.m4 556168515Sgshapiro cf/feature/require_rdns.m4 557168515Sgshapiro devtools/M4/UNIX/check.m4 558168515Sgshapiro include/sm/misc.h 559168515Sgshapiro include/sm/sendmail.h 560168515Sgshapiro include/sm/tailq.h 561168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 562168515Sgshapiro libmilter/docs/smfi_setsymlist.html 563168515Sgshapiro libmilter/docs/xxfi_data.html 564168515Sgshapiro libmilter/docs/xxfi_negotiate.html 565168515Sgshapiro libmilter/docs/xxfi_unknown.html 566168515Sgshapiro libmilter/example.c 567168515Sgshapiro libmilter/monitor.c 568168515Sgshapiro libmilter/worker.c 569168515Sgshapiro libsm/memstat.c 570168515Sgshapiro libsm/t-memstat.c 571168515Sgshapiro libsm/t-qic.c 572168515Sgshapiro libsm/util.c 573168515Sgshapiro sendmail/daemon.h 574168515Sgshapiro sendmail/map.h 575168515Sgshapiro 576161389Sgshapiro8.13.8/8.13.8 2006/08/09 577161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 578161389Sgshapiro the server can erroneously report that there is 579161389Sgshapiro insufficient disk space. Additionally make sure that 580161389Sgshapiro an internal variable is set properly to avoid those 581161389Sgshapiro misleading errors. Based on patch from Steve Hubert 582161389Sgshapiro of University of Washington. 583161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 584161389Sgshapiro the process that forks the daemon exited, i.e., if 585161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 586161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 587161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 588161389Sgshapiro David F. Skoll. 589161389Sgshapiro Avoid a crash when finishing due to referencing a freed variable. 590161389Sgshapiro Problem reported and diagnosed by Moritz Jodeit. 591161389Sgshapiro CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4 592161389Sgshapiro range (0..255). 593161389Sgshapiro LIBMILTER: The "hostname" argument of the xxfi_connect() callback 594161389Sgshapiro previously was the equivalent of {client_ptr}. However, 595161389Sgshapiro this did not match the documentation of the function, hence 596161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 597161389Sgshapiro about these macros. 598161389Sgshapiro 599159609Sgshapiro8.13.7/8.13.7 2006/06/14 600159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 601159609Sgshapiro crash while trying to send a mail due to a stack overflow, 602159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 603159609Sgshapiro happens because the recursion of the function mime8to7() 604159609Sgshapiro was not restricted. The function is called for MIME 8 to 605159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 606159609Sgshapiro To work around this problem, recursive calls are limited to 607159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 608159609Sgshapiro limit is treated as opaque and is not checked further. 609159609Sgshapiro Problem noted by Frank Sheiness. 610159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 611159609Sgshapiro SASL mechanisms that use the security layer, e.g., 612159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 613159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 614159609Sgshapiro a df file might have been left behind in the queue. 615159609Sgshapiro This was another side effect of the changes to the I/O 616159609Sgshapiro layer made in 8.13.6. 617159609Sgshapiro Several minor problems have been fixed that were found by a 618159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 619159609Sgshapiro distribution. See http://scan.coverity.com/ 620159609Sgshapiro Note: the scan generated also a lot of "false positives", 621159609Sgshapiro e.g., "error" reports about situations that cannot happen. 622159609Sgshapiro Most of those code places are marked with lint(1) comments 623159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 624159609Sgshapiro Hence an explicit assertion has been added in some cases 625159609Sgshapiro to avoid those false positives. 626159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 627159609Sgshapiro error then in some cases shared memory segments or pid 628159609Sgshapiro files were not removed. 629159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 630159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 631159609Sgshapiro reported by Akihiro Sagawa. 632159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 633159609Sgshapiro bug work-around. Hence if sendmail is linked against 634159609Sgshapiro either of these versions and compression is available, 635159609Sgshapiro the padding bug work-around is turned off. Based on 636159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 637159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 638159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 639159609Sgshapiro however, that list is no longer available. To avoid 640159609Sgshapiro further problems, no default value is available anymore, 641159609Sgshapiro but an argument must be specified. 642159609Sgshapiro Portability: 643159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c.

Also fix handling of 650157001Sgshapiro a buffer in sm_syslog() which could have been used as an 651157001Sgshapiro attack vector to exploit the unsafe handling of 652157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 653157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 654157001Sgshapiro Handle theoretical integer overflows that could triggered if 655157001Sgshapiro the server accepted headers larger than the maximum 656157001Sgshapiro (signed) integer value. This is prevented in the default 657157001Sgshapiro configuration by restricting the size of a header, and on 658157001Sgshapiro most machines memory allocations would fail before reaching 659157001Sgshapiro those values. Problems found by Phil Brass of ISS. 660157001Sgshapiro If a server returns 421 for an RSET command when trying to start 661157001Sgshapiro another transaction in a session while sending mail, do 662157001Sgshapiro not trigger an internal consistency check. Problem found 663157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 664157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 665157001Sgshapiro to a STARTTLS command despite the fact that it advertised 666157001Sgshapiro STARTTLS and that the code is not valid according to RFC 667157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 668157001Sgshapiro of a protocol error (which has been changed to a 669157001Sgshapiro temporary error in 8.13.5).

This structure is used decide whether there 701157001Sgshapiro is enough free disk space when selecting a queue, hence 702157001Sgshapiro without this change queue selection could fail if a df/ 703157001Sgshapiro subdirectory exists and is on a different filesystem 704157001Sgshapiro than the base directory. 705157001Sgshapiro Use the queue index of the df file (instead of the qf file) for 706157001Sgshapiro checking whether a link(2) operation can be used to split 707157001Sgshapiro an envelope across queue groups. Problem found by 708157001Sgshapiro Werner Wiethege. 709157001Sgshapiro If the list of items in the queue is larger than the maximum 710157001Sgshapiro number of items to process, sort the queue first and 711157001Sgshapiro then cut the list off instead of the other way around. 712157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 713157001Sgshapiro Fix helpfile to show full entry for ETRN.

Problem noted by Juergen Georgi 923132943Sgshapiro of RUS University of Stuttgart. 924132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 925132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 926132943Sgshapiro Add support for LDAP recursion based on types given to attribute 927132943Sgshapiro specifications in an LDAP map definition. This allows 928132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 929132943Sgshapiro URL which will in turn be queried. See the ``LDAP 930132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 931132943Sgshapiro Based on patch from Andrew Baucom. 932132943Sgshapiro Extend the default LDAP specifications for AliasFile 933132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 934132943Sgshapiro include support for LDAP recursion via new attributes. 935132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 936132943Sgshapiro of cf/README for more information. 937132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 938132943Sgshapiro LDAP API/protocol version to use. The default depends on 939132943Sgshapiro the LDAP library. 940132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 941132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 942132943Sgshapiro and -p port. This also allows for the use of LDAP over 943132943Sgshapiro SSL and connections via named sockets if your LDAP 944132943Sgshapiro library supports it. 945132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 946132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 947132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 948132943Sgshapiro during a SMTP session then terminate it just like it is 949132943Sgshapiro done for too many bad SMTP commands. 950132943Sgshapiro Basic connection rate control support has been added: the daemon 951132943Sgshapiro maintains the number of incoming connections per client 952132943Sgshapiro IP address and total in the macros {client_rate} and 953132943Sgshapiro {total_rate}, respectively. These macros can be used 954132943Sgshapiro in the cf file to impose connection rate limits. 955132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 956132943Sgshapiro determines the length of the interval for which the 957132943Sgshapiro number of connections is stored. Based on patch from 958132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 959132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 960132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 961132943Sgshapiro If enabled by the new ruleset greet_pause (see 962132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 963132943Sgshapiro amount of time before sending the initial 220 SMTP 964132943Sgshapiro greeting. If any traffic is received before then, a 554 965132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 966132943Sgshapiro during that connection. 967132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 968132943Sgshapiro server could sleep for a very long time. Fix based on 969132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 970132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 971132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 972132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 973132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 974132943Sgshapiro misinterpret it as a permanent error. 975132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 976132943Sgshapiro all milters accepted the mail. This can increase 977132943Sgshapiro performance if many mails are rejected by milters due to 978132943Sgshapiro body scans. Based on patch from David F. Skoll. 979132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 980132943Sgshapiro header, whether provided by the client or generated by 981132943Sgshapiro sendmail. 982132943Sgshapiro New macro {client_connections} which contains the number of open 983132943Sgshapiro connections in the SMTP server for the client IP address. 984132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 985132943Sgshapiro Mines de Paris. 986132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 987132943Sgshapiro to prevent confusion caused by running sendmail stop 988132943Sgshapiro scripts two or more times, where the second and subsequent 989141858Sgshapiro runs would report misleading error messages about sendmail's 990132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 991132943Sgshapiro for a discussion of the implications of this, including 992132943Sgshapiro how to correct broken scripts which may have depended on 993132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 994132943Sgshapiro Support per-daemon input filter lists which override the default 995132943Sgshapiro filter list specified in InputMailFilters. The filters 996132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 997132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 998132943Sgshapiro your configuration relies on this behavior, you have to 999132943Sgshapiro add those names to class 'w' yourself. Problem noted 1000132943Sgshapiro by Sander Eerkes. 1001132943Sgshapiro Support message quarantining in the mail queue. Quarantined 1002132943Sgshapiro messages are not run on normal queue displays or runs 1003132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 1004132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 1005132943Sgshapiro The -q command line option now can specify which queue to display 1006132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 1007132943Sgshapiro operates on lost queue items. 1008132943Sgshapiro Restricted mail queue runs and displays can be done based on the 1009132943Sgshapiro quarantined reason using -qQtext to run or display 1010132943Sgshapiro quarantined items if the quarantine reason contains the 1011132943Sgshapiro given text. Similarly, -q!Qtext will run or display 1012132943Sgshapiro quarantined items which do not have the given text in the 1013132943Sgshapiro quarantine reason. 1014132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 1015132943Sgshapiro new -Q option. See doc/op/op.me for more information. 1016132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 1017132943Sgshapiro quarantine reason is shown in a new line prefixed by 1018132943Sgshapiro "QUARANTINE:". 1019132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 1020132943Sgshapiro to quarantine messages in check_* (except check_compat) and 1021132943Sgshapiro header check rulesets. The $: of the mailer triplet will 1022132943Sgshapiro be used for the quarantine reason. 1023132943Sgshapiro Add a new quarantine count to the mailstats collected. 1024132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 1025132943Sgshapiro message if it is quarantined. 1026132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 1027132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 1028132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 1029132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 1030132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 1031132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 1032132943Sgshapiro lookup for the client IP address. Note: this is the same 1033132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 1034132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 1035132943Sgshapiro recipients received so far in a transaction. 1036132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 1037132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 1038132943Sgshapiro noted by Kai Schlichting. 1039132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 1040132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 1041132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 1042132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 1043132943Sgshapiro Wolfhugel of France Telecom Oleane. 1044132943Sgshapiro Do not silently truncate long strings in address rewriting. 1045132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 1046132943Sgshapiro Oceana Matrix Ltd. 1047132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 1048132943Sgshapiro support mutual authentication. From Kenneth Murchison of 1049132943Sgshapiro Oceana Matrix Ltd. 1050132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 1051132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 1052132943Sgshapiro format just like the STARTTLS related macros to avoid 1053132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 1054132943Sgshapiro Masarati of SysNet s.n.c. 1055132943Sgshapiro New option AuthRealm to set the authentication realm that is 1056132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 1057132943Sgshapiro of the University of Manitoba. 1058132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 1059132943Sgshapiro successful, otherwise relaying would be allowed if 1060132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 1061132943Sgshapiro is active. 1062132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 1063132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 1064132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 1065132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 1066132943Sgshapiro DIGEST-MD5 and LOGIN. 1067132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 1068132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 1069132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 1070132943Sgshapiro overwrite each other's pid files. 1071132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 1072132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 1073132943Sgshapiro Wolfhugel of France Telecom. 1074132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 1075132943Sgshapiro LogLevel 12 or higher. 1076132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 1077132943Sgshapiro try to use the SMTP command VERB to propagate this option 1078132943Sgshapiro to the MTA which in turn will show the delivery just like 1079132943Sgshapiro it was done before the default 8.12 separation of MSP and 1080132943Sgshapiro MTA. Based on patch by Per Hedeland. 1081132943Sgshapiro If a daemon is refusing connections for longer than the time specified 1082132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 1083132943Sgshapiro to high load, log this information. Patch from John Beck 1084132943Sgshapiro of Sun Microsystems. 1085132943Sgshapiro Remove the ability for non-trusted users to raise the value of 1086132943Sgshapiro CheckpointInterval on the command line. 1087132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 1088132943Sgshapiro subset of the functionality of the 's' flag. 1089132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 1090132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 1091132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 1092132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 1093132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 1094132943Sgshapiro causing subsequent messages to be sent instead of being 1095132943Sgshapiro discarded. This also caused milter callbacks to be called 1096132943Sgshapiro out of order after the SMTP session was reset. 1097132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 1098132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 1099132943Sgshapiro further information. 1100132943Sgshapiro New command line option -D logfile to send debug output to 1101132943Sgshapiro the indicated log file instead of stdout. 1102132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 1103132943Sgshapiro queue return and warning times for delivery status 1104132943Sgshapiro notifications. 1105132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 1106132943Sgshapiro at all. 1107132943Sgshapiro Several more return values for ruleset srv_features have been added 1108132943Sgshapiro to enable/disable certain features in the server per 1109132943Sgshapiro connection. See doc/op/op.me for details. 1110132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 1111132943Sgshapiro for DaemonPortOptions. 1112132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 1113132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 1114132943Sgshapiro of Northern Illinois University. 1115132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 1116132943Sgshapiro be tried as a last resort after all other fallbacks. This 1117132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 1118132943Sgshapiro view of inside the company, but an incomplete view of 1119132943Sgshapiro outside). From John Beck of Sun Microsystems. 1120132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 1121132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 1122132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 1123132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 1124132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 1125132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 1126132943Sgshapiro of the University of Illinois at Urbana-Champaign. 1127132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 1128132943Sgshapiro applications for use in the xxfi_eom() callback. 1129132943Sgshapiro New macro {time} which contains the output of the time(3) function, 1130132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 1131132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 1132132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 1133132943Sgshapiro terminate the SMTP session with a 421 error message. 1134132943Sgshapiro Get rid of dead code that tried to access the environment variable 1135132943Sgshapiro HOSTALIASES. 1136132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 1137132943Sgshapiro compile with -DUSE_TTYPATH=1. 1138132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 1139132943Sgshapiro the header value passed in without balancing quotes, 1140132943Sgshapiro parentheses, and angle brackets. Based on patch from 1141132943Sgshapiro Oleg Bulyzhin. 1142132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 1143132943Sgshapiro angle brackets when reading in rulesets. This allows 1144132943Sgshapiro rules to be written for header checks to catch strings 1145132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 1146132943Sgshapiro Based on patch from Oleg Bulyzhin. 1147132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 1148132943Sgshapiro some temporary errors like ECONNABORTED. 1149132943Sgshapiro Added list of CA certificates that are used by members of the 1150132943Sgshapiro sendmail consortium, see CACerts. 1151132943Sgshapiro Portability: 1152132943Sgshapiro Two new compile options have been added: 1153132943Sgshapiro HASCLOSEFROM System has closefrom(3). 1154132943Sgshapiro HASFDWALK System has fdwalk(3). 1155132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 1156132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 1157132943Sgshapiro change to using fcntl() locking until they can fix 1158132943Sgshapiro it. Be sure to update other sendmail related 1159132943Sgshapiro programs to match locking techniques. 1160132943Sgshapiro New compile time option NEEDINTERRNO which should be set 1161132943Sgshapiro if <errno.h> does not declare errno itself. 1162132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 1163132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 1164132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 1165132943Sgshapiro Center for Scientific Computing. 1166132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 1167132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 1168132943Sgshapiro Remove path from compiler definition for Interix because 1169132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 1170132943Sgshapiro Also use <sys/mkdev.h> to get the correct 1171132943Sgshapiro major()/minor() definitions. Based on feedback 1172132943Sgshapiro from Mark Funkenhauser. 1173132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 1174132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 1175132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 1176132943Sgshapiro cf/sendmail.schema for more information. 1177132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 1178132943Sgshapiro is of the form "user:group" when used for submit.mc. 1179132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 1180132943Sgshapiro of Northern Illinois University. 1181132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 1182132943Sgshapiro instructs the check_* (except check_compat) to quarantine 1183132943Sgshapiro the message using the given reason. 1184132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 1185132943Sgshapiro instead of "host" to avoid problem with looking up other 1186132943Sgshapiro DNS records than just A. 1187132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 1188132943Sgshapiro length of the interval for which the number of incoming 1189132943Sgshapiro connections is maintained. 1190132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 1191132943Sgshapiro rate control for individual hosts or nets. 1192132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 1193132943Sgshapiro number of open SMTP connections for individual hosts or nets. 1194132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 1195132943Sgshapiro slamming protection described above. The feature can 1196132943Sgshapiro take an argument specifying the milliseconds to wait and/or 1197132943Sgshapiro use the access database to look the pause time based on 1198132943Sgshapiro client hostname, domain, IP address, or subnet. 1199132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 1200132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 1201132943Sgshapiro rejections based on the unverified hostname of client, 1202132943Sgshapiro which turns on the same behavior as in earlier sendmail 1203132943Sgshapiro versions when delay_checks was not in use.

This change has been made to 1689102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 1690102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 1691102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1692102528Sgshapiro modification causes a change of behavior if an IP net/address 1693102528Sgshapiro is listed in the access map with REJECT and a host/domain 1694102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1695102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1696102528Sgshapiro change was made on request of Neil Rickert of Northern 1697102528Sgshapiro Illinois University, the side effect has been found by 1698102528Sgshapiro Stefaan Van Hoornick. 1699102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1700102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1701102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1702102528Sgshapiro University. 1703102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1704102528Sgshapiro Fix from Andrzej Filip. 1705102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1706102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1707102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1708102528Sgshapiro NULL pointer.

In previous versions this could cause mail 184594334Sgshapiro not to be delivered if a queue file is repeatedly moved 184694334Sgshapiro by an external process whenever sendmail moved it back 184794334Sgshapiro into the right place. Some precautions have been taken 184894334Sgshapiro to avoid moving queue files if not really necessary. 184994334Sgshapiro sendmail may use links to refer to queue files and it 185094334Sgshapiro may store the path of data files in queue files. Hence 185194334Sgshapiro queue files should not be moved unless those internals 185294334Sgshapiro are understood and the integrity of the files is not 185394334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 185494334Sgshapiro University. 185594334Sgshapiro If an error mail is created, and the mail is split across different 185694334Sgshapiro queue directories, and SuperSafe is off, then write the mail 185794334Sgshapiro to disk before splitting it, otherwise an assertion is 185894334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 185994334Sgshapiro of INTERMETA. 186094334Sgshapiro Fix possible race condition that could cause sendmail to forget 186194334Sgshapiro running queues.

Based on patch from Dirk Meyer 187494334Sgshapiro of Dinoex. 187594334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 187694334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 187794334Sgshapiro Polytechnic Institute. 187894334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 187994334Sgshapiro if several mails are sent in one session and some of them 188094334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 188194334Sgshapiro Change timeout check such that cached information about a connection 188294334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 188394334Sgshapiro Based on patch from David Burns of Portland State University. 188494334Sgshapiro Properly count message size for mailstats during mail collection. 188594334Sgshapiro Problem noted by Werner Wiethege. 188694334Sgshapiro Log complete response from LMTP delivery agent on failure.

Patch from Servaas 189794334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 189894334Sgshapiro Properly deal with a case where sendmail is called by root running 189994334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 190094334Sgshapiro Lusky of ISS Atlanta. 190194334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 190294334Sgshapiro directories are used and mail is sent to a mailing list 190394334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 190494334Sgshapiro of Concordia University. 190594334Sgshapiro Fix class map parsing code if optional key is specified. Problem 190694334Sgshapiro found by Mario Nigrovic. 190794334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 190894334Sgshapiro incoming messages. A leading dot is always stripped by the 190994334Sgshapiro SMTP receiver regardless of whether or not it is followed by 191094334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 191194334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 191294334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 191394334Sgshapiro Elvers. 191494334Sgshapiro Correct the statistics gathered for total number of connections. 191594334Sgshapiro Instead of being the exact same number as the total number 191694334Sgshapiro of messages (T line in mailstats) it now represents the 191794334Sgshapiro total number of TCP connections. 191894334Sgshapiro Be more explicit about syntax errors in addresses, especially 191994334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 192094334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 192194334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 192294334Sgshapiro are used.

Based on 193094334Sgshapiro patch by Bryan Costales. 193194334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 193294334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 193394334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 193494334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 193594334Sgshapiro errors. By doing so, the host was marked as having a 193694334Sgshapiro temporary problem and other mail destined for that host was 193794334Sgshapiro queued for the next queue run. Problem noted by Fletcher 193894334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 193994334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 194094334Sgshapiro and Neil Rickert of Northern Illinois University. 194194334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 194294334Sgshapiro which drop the connection instead of responding to the 194394334Sgshapiro command). 194494334Sgshapiro Portability: 194594334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 194698121Sgshapiro available. 194794334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 194894334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 194994334Sgshapiro settings. Patch from Elias Halldor Agustsson of 195094334Sgshapiro Skyrr. 195194334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 195294334Sgshapiro noted by John Beck. 195394334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 195494334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 195594334Sgshapiro Rajesh Somasund of Hewlett-Packard. 195694334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 195794334Sgshapiro SMTP AUTH information. This feature was actually added in 195894334Sgshapiro 8.12.0 but a release note was not included. 195994334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 196094334Sgshapiro parameter is set and the LDAP lookup returns a temporary 196194334Sgshapiro error. 196294334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 196394334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 196494334Sgshapiro Krzysztof Oledzki. 196594334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 196694334Sgshapiro initialization as aliases are not needed for the MSP. 196794334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 196894334Sgshapiro is in use. Patch from Andrzej Filip. 196994334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 197094334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 197194334Sgshapiro This will only have an effect if a parameter is specified, 197294334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 197394334Sgshapiro it is embedded in square brackets. Problem noted by 197494334Sgshapiro Theo Van Dinter of Collective Technologies. 197594334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 197694334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 197794334Sgshapiro to allow for the proper time zone on systems where the 197894334Sgshapiro default results in misleading time stamps. That is, syslog 197994334Sgshapiro time stamps and Date headers on submitted mail will use the 198094334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 198194334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 198294334Sgshapiro by Neil Rickert of Northern Illinois University. 198394334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 198494334Sgshapiro binary. Adjust local mailer flags accordingly.

Notice: 199598121Sgshapiro this fix requires that sendmail and libmilter both have 199698121Sgshapiro this change; mixing versions may lead to wrong port 199794334Sgshapiro values depending on the endianness of the involved systems. 199894334Sgshapiro Problem noted by Gisle Aas of ActiveState. 199994334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 200094334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 200194334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 200294334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 200394334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 200494334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 200594334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 200694334Sgshapiro this to 1 if your LDAP client libraries include 200794334Sgshapiro ldap_memfree(). 200894334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 200994334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 201094334Sgshapiro SMRSH: Fix compilation problem on some operating systems.

Problem noted by Bjoern Voigt of TU Berlin. 208390792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 208490792Sgshapiro server gets stuck while processing that command. Problem 208590792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 208690792Sgshapiro In addition to printing errors when parsing recipients during 208790792Sgshapiro command line invocations log them to make it simpler 208890792Sgshapiro to understand possible DSNs to postmaster. 208990792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 209090792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 209190792Sgshapiro instead of forcing localhost. 209290792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 209390792Sgshapiro submit.cf.

Problem 209590792Sgshapiro noted by Neil Rickert of Northern Illinois University. 209690792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 209790792Sgshapiro dropping the connection during an SMTP transaction, stop 209890792Sgshapiro sending commands. This prevents bogus "Bad file number" 209990792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 210090792Sgshapiro Worcester Polytechnic Institute. 210190792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 210290792Sgshapiro almost always too small; do not guess the size at all. 210390792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 210490792Sgshapiro Compaq Computer Corp. 210590792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 210690792Sgshapiro properly. Problem noted by Valdis Kletnieks of Virginia 210790792Sgshapiro Tech. 210890792Sgshapiro Portability: 210990792Sgshapiro Fix IPv6 network interface probing on HP-UX 11.X. Based on 211090792Sgshapiro patch provided by HP. 211190792Sgshapiro Mac OS X (aka Darwin) has a broken setreuid() call, but a 211290792Sgshapiro working seteuid() call. From Daniel J.

From Ganu 211490792Sgshapiro Sachin of Siemens. 211590792Sgshapiro Set SM_IO_MIN_BUF (4K) and SM_IO_MAX_BUF (8K) for HP-UX. 211690792Sgshapiro Reduce optimization from +O3 to +O2 on HP-UX 11. This 211790792Sgshapiro fixes a problem that caused additional bogus 211890792Sgshapiro characters to be written to the qf file. Problem 211990792Sgshapiro noted by Tapani Tarvainen. 212090792Sgshapiro Set LDA_USE_LOCKF by default for UnixWare. Problem noted 212190792Sgshapiro by Boyd Lynn Gerber. 212290792Sgshapiro Add support for HP MPE/iX. See sendmail/README for port 212390792Sgshapiro information. From Mark Bixby of Hewlett-Packard. 212490792Sgshapiro New portability defines HASNICE, HASRRESVPORT, USE_ENVIRON, 212590792Sgshapiro USE_DOUBLE_FORK, and NEEDLINK. See sendmail/README 212690792Sgshapiro for more information. From Mark Bixby of 212790792Sgshapiro Hewlett-Packard. 212890792Sgshapiro If an OS doesn't have a method of finding free disk space 212990792Sgshapiro (SFS_NONE), lie and say there is plenty of space. 213090792Sgshapiro From Mark Bixby of Hewlett-Packard. 213190792Sgshapiro Add support for AIX 5.1.

Problem noted by Nikos Voutsinas of the 216590792Sgshapiro University of Athens. 216690792Sgshapiro New Files: 216790792Sgshapiro cf/cf/generic-mpeix.cf 216890792Sgshapiro cf/cf/generic-mpeix.mc 216990792Sgshapiro cf/ostype/freebsd5.m4 217090792Sgshapiro cf/ostype/mpeix.m4 217190792Sgshapiro devtools/OS/AIX.5.1 217290792Sgshapiro devtools/OS/MPE-iX 217390792Sgshapiro include/sm/os/sm_os_mpeix.h 217490792Sgshapiro libsm/mpeix.c 217590792Sgshapiro 217690792Sgshapiro8.12.1/8.12.1 2001/10/01 217790792Sgshapiro SECURITY: Check whether dropping group privileges actually succeeded 217890792Sgshapiro to avoid possible compromises of the mail system by 217990792Sgshapiro supplying bogus data. Add configuration options for 218090792Sgshapiro different set*gid() calls to reset saved gid. Problem 218190792Sgshapiro found by Michal Zalewski. 218290792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 218390792Sgshapiro privileges by disabling debugging (command line -d flag) 218490792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 218590792Sgshapiro used. Suggested by Michal Zalewski. 218690792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 218790792Sgshapiro Problem found by Michal Zalewski. 218890792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 218990792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 219090792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 219190792Sgshapiro If debugging is turned on (-d0.10) print not just the default 219290792Sgshapiro values for configuration file and pid file but also the 219390792Sgshapiro selected values. Problem noted by Brad Chapman. 219490792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 219590792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 219690792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 219790792Sgshapiro this only applied to hostname canonification. Problem 219890792Sgshapiro noted by Bill Fenner of AT&T Research. 219990792Sgshapiro Ignore comments in NIS host records when trying to find the 220090792Sgshapiro canonical name for a host. 220190792Sgshapiro When sendmail has extra privileges, limit mail submission command 220290792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 220390792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 220490792Sgshapiro suggestion from Michal Zalewski. 220590792Sgshapiro Portability: 220690792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 220790792Sgshapiro `uname` does not given complete information. 220890792Sgshapiro Problem noted by Keith Neufeld of the Cessna 220990792Sgshapiro Aircraft Company. 221090792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 221190792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 221290792Sgshapiro Avoid compiler warnings by not using pointers to pass 221390792Sgshapiro integers. Problem noted by Todd C. Miller of 221490792Sgshapiro Courtesan Consulting. 221590792Sgshapiro CONFIG: Add restrictqrun to PrivacyOptions for the MSP to minimize 221690792Sgshapiro problems with potential misconfigurations. 221790792Sgshapiro CONFIG: Fix comment showing default value of MaxHopCount.

You need to create a new user and 224690792Sgshapiro a new group before installing sendmail (both called smmsp by 224790792Sgshapiro default). The installation process tries to install 224890792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 224990792Sgshapiro default. Please see sendmail/SECURITY for details. 225090792Sgshapiro SECURITY: Check for group and world writable forward and :include: 225190792Sgshapiro files.

Suggested 226090792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 226190792Sgshapiro (IdS). 226290792Sgshapiro Fixed problem of a global variable being used for a timeout jump 226390792Sgshapiro point where the variable could become overused for more than 226490792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 226590792Sgshapiro a corrupted stack causing a core dump. The timeout is now 226690792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 226790792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 226890792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 226990792Sgshapiro checks (group ID of RunAsUser). This allows use of a 227090792Sgshapiro set-group-ID sendmail binary for initial message submission 227190792Sgshapiro and no set-user-ID root sendmail is needed. For details 227290792Sgshapiro see sendmail/SECURITY. 227390792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 227490792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 227590792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 227690792Sgshapiro with a fallback of sendmail.cf as configuration file. See 227790792Sgshapiro sendmail/SECURITY. 227890792Sgshapiro New configuration file option UseMSP to allow group writable queue 227990792Sgshapiro files if the group is the same as that of a set-group-ID 228090792Sgshapiro sendmail binary. See sendmail/SECURITY. 228190792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 228290792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 228390792Sgshapiro is sendmail.cf (to be backward compatible). This selection 228490792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 228590792Sgshapiro file: client or mta). See sendmail/SECURITY. 228690792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 228790792Sgshapiro command has been removed. 228890792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 228990792Sgshapiro at compile time or per host (ruleset). 229090792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 229190792Sgshapiro used to look up local mail recipients; the default value 229290792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 229390792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 229490792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 229590792Sgshapiro long, to accomodate envelope splitting. File systems with 229690792Sgshapiro a 14 character file name length limit are no longer 229790792Sgshapiro supported. 229890792Sgshapiro Recipient list used for delivery now gets internally ordered by 229990792Sgshapiro hostsignature (character string version of MX RR). This orders 230090792Sgshapiro recipients for the same MX RR's together meaning smaller 230190792Sgshapiro portions of the list need to be scanned (instead of the whole 230290792Sgshapiro list) each delivery() pass to determine piggybacking. The 230390792Sgshapiro significance of the change is better the larger the recipient 230490792Sgshapiro list. Hostsignature is now created during recipient list 230590792Sgshapiro creation rather than just before delivery. 230690792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 230790792Sgshapiro piggybacking (called coincidental) extended to coattail 230890792Sgshapiro piggybacking. Rather than complete MX RR matching 230990792Sgshapiro (coincidental) piggybacking is done if just the lowest value 231090792Sgshapiro preference matches (coattail). 231190792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 231290792Sgshapiro try other MX hosts if available. 231390792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 231490792Sgshapiro outgoing (client-side) SMTP Authentication. 231590792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 231690792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 231790792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 231890792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 231990792Sgshapiro A new ruleset authinfo can be used to return client side 232090792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 232190792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 232290792Sgshapiro removed in future versions. 232390792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 232490792Sgshapiro requires 334. Mercury 1.48 is a known offender. 232590792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 232690792Sgshapiro for the security layer in SMTP AUTH (SASL). See 232790792Sgshapiro doc/op/op.me for details. 232890792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 232990792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 233090792Sgshapiro signed the presented certificate, the CN and the MD5 hash 233190792Sgshapiro of the presented certificate, respectively. 233290792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 233390792Sgshapiro New ruleset srv_features to enable/disable certain features in the 233490792Sgshapiro server per connection. See doc/op/op.me for details. 233590792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 233690792Sgshapiro recipient; useful to decide whether a conection is secure 233790792Sgshapiro enough on a per recipient basis. 233890792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 233990792Sgshapiro for STARTTLS. 234090792Sgshapiro If no certificate has been requested, the macro {verify} has the 234190792Sgshapiro value "NOT". 234290792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 234390792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 234490792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 234590792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 234690792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 234790792Sgshapiro really required. This change results in a noticable 234890792Sgshapiro performance gains on most machines. Moreover, if shared 234990792Sgshapiro memory is in use, reuse the key several times. 235090792Sgshapiro Add queue groups which can be used to group queue directories with 235190792Sgshapiro the same behavior together. See doc/op/op.me for details. 235290792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 235390792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 235490792Sgshapiro are initially sorted which may result in faster envelope 235590792Sgshapiro splitting. If the mail is submitted directly from the 235690792Sgshapiro command line, then the value also limits the number of 235790792Sgshapiro processes to deliver the envelopes; if more envelopes are 235890792Sgshapiro created they are only queued up and must be taken care of 235990792Sgshapiro by a queue run. 236090792Sgshapiro The check for 'enough disk space' now pays attention to which file 236190792Sgshapiro system each queue directory resides in. 236290792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 236390792Sgshapiro New option QueueFileMode for the default permissions of queue files. 236490792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 236590792Sgshapiro group (one or more queues in a multi-queue environment 236690792Sgshapiro collected together) to process the same work list at the 236790792Sgshapiro same time. 236890792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 236990792Sgshapiro active queue runner processes. 237090792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 237190792Sgshapiro runners per queue group. 237290792Sgshapiro Queue member selection by substring pattern matching now allows 237390792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 237490792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 237590792Sgshapiro of the queue that match during processing. 237690792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 237790792Sgshapiro periodically forking a child to process the queue, a single 237890792Sgshapiro child is forked for each queue that sleeps between queue 237990792Sgshapiro runs. A SIGHUP signal can be sent to restart this 238090792Sgshapiro persistent queue runner. 238190792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 238290792Sgshapiro sendmail process which only runs the queue at an interval: 238390792Sgshapiro sendmail -q15m). 238490792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 238590792Sgshapiro Proposed by Thom O'Connor. 238690792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 238790792Sgshapiro unless the new -qf option or -v is used. 238890792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 238990792Sgshapiro several queue runners are started by hand to avoid contention. 239090792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 239190792Sgshapiro of the qf file (older entries first). 239290792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 239390792Sgshapiro a client to specify an amount of time within which an e-mail 239490792Sgshapiro should be delivered. New option DeliverByMin added to set the 239590792Sgshapiro minimum amount of time or disable the extension. 239690792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 239790792Sgshapiro not allowed unless escaped or quoted. 239890792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 239990792Sgshapiro by Leif Johansson of Stockholm University, which was based on 240090792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 240190792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 240290792Sgshapiro Technology, Stockholm, Sweden. 240390792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 240490792Sgshapiro behavior (no MX lookups), put the name in square brackets. 240590792Sgshapiro Proposed by Thom O'Connor. 240690792Sgshapiro Use shared memory to store free space of filesystems that are used 240790792Sgshapiro for queues, if shared memory is available and if a key is set 240890792Sgshapiro via SharedMemoryKey. This minimizes the number of system 240990792Sgshapiro calls to check the available space. See doc/op/op.me for 241090792Sgshapiro details. 241190792Sgshapiro If shared memory is compiled in the option -bP can be used to print 241290792Sgshapiro the number of entries in the queue(s). 241390792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 241490792Sgshapiro and the usual documentation for details. 241590792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 241690792Sgshapiro Remove '-U' (initial user submission) command line option as 241790792Sgshapiro announced in 8.10. 241890792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 241990792Sgshapiro New macro {addr_type} which contains whether the current address is 242090792Sgshapiro an envelope sender or recipient address. Suggested by 242190792Sgshapiro Neil Rickert of Northern Illinois University. 242290792Sgshapiro Two new options for host maps: -d (retransmission timeout), 242390792Sgshapiro -r (number of retries). 242490792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 242590792Sgshapiro separator such that a lookup can return both an attribute 242690792Sgshapiro and value separated by the given separator. 242790792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 242890792Sgshapiro to map class arith. 242990792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 243090792Sgshapiro (errors that occur when sending an error message) are dropped. 243190792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 243290792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 243390792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 243490792Sgshapiro requirements for files containing secret keys. This is 243590792Sgshapiro necessary for the MSP if client authentification is used. 243690792Sgshapiro Properly handle quoted filenames for class files (to allow for 243790792Sgshapiro filenames with spaces). 243890792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 243990792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 244090792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 244190792Sgshapiro {if_addr_out} address of interface of outgoing connection. 244290792Sgshapiro {if_family_out} family of interface of outgoing connection. 244390792Sgshapiro The latter two are only set if the interface does not belong 244490792Sgshapiro to the loopback net. 244590792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 244690792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 244790792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 244890792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 244990792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 245090792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 245190792Sgshapiro all connections for a single delivery attempt to succeed. 245290792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 245390792Sgshapiro a threshold number of recipients has been rejected (option 245490792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 245590792Sgshapiro Development Group. 245690792Sgshapiro New option DelayLA to delay connections if the load averages 245790792Sgshapiro exceeds the specified value. The default of 0 does not 245890792Sgshapiro change the previous behavior. A value greater than 0 245990792Sgshapiro will cause sendmail to sleep for one second on most 246090792Sgshapiro SMTP commands and before accepting connections if that 246190792Sgshapiro load average is exceeded. 246290792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 246390792Sgshapiro recipients that are sent during a connection to a mailer. 246490792Sgshapiro This also introduces a new mailer field 'r' which defines 246590792Sgshapiro the maximum number of recipients (defaults to 100). 246690792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 246790792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 246890792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 246990792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 247090792Sgshapiro instead. 247190792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 247290792Sgshapiro builtin mailer pathnames. Use TCP instead. 247390792Sgshapiro PH map code updated to use the new libphclient API instead of the 247490792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 247590792Sgshapiro University of Illinois at Urbana-Champaign. 247690792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 247790792Sgshapiro for direct (command line) submissions. 247890792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 247990792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 248090792Sgshapiro Hagino of the KAME Project. 248190792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 248290792Sgshapiro whose content is rewritten similar to Reply-To:. 248390792Sgshapiro Proposed by Andrzej Filip. 248490792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 248590792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 248690792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 248790792Sgshapiro AUTH/STARTTLS related logfile entries. 248890792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 248990792Sgshapiro before logging. 249090792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 249190792Sgshapiro (at LogLevel 9/10 or higher). 249290792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 249390792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 249490792Sgshapiro in which most commands are rejected due to check_relay or 249590792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 249690792Sgshapiro Change logging format for cloned envelopes to be similar to that for 249790792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 249890792Sgshapiro of the Universitat Regensburg. 249990792Sgshapiro Added libsm, a C library of general purpose abstractions including 250090792Sgshapiro assertions, tracing and debugging with named debug categories, 250190792Sgshapiro exception handling, malloc debugging, resource pools, 250290792Sgshapiro portability abstractions, and an extensible buffered I/O 250390792Sgshapiro package. It will at some point replace libsmutil. 250490792Sgshapiro See libsm/index.html for details. 250590792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 250690792Sgshapiro care of by fork() and exit(). 250790792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 250890792Sgshapiro more consistent portablity amongst different platforms 250990792Sgshapiro new and old (from new libsm). 251090792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 251190792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 251290792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 251390792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 251490792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 251590792Sgshapiro synchronizations calls. 251690792Sgshapiro Add per-recipient status information to mailq -v output. 251790792Sgshapiro T_ANY queries are no longer used by sendmail. 251890792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 251990792Sgshapiro too (see include/sm/cdefs.h for more info). 252090792Sgshapiro sendmail -d now has general support for named debug categories. 252190792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 252290792Sgshapiro for details. 252390792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 252490792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 252590792Sgshapiro generated by this condition were illegal (not RFC conform). 252690792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 252790792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 252890792Sgshapiro mailer and the recipient has hence been rejected during the 252990792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 253090792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 253190792Sgshapiro that do not have postmaster defined. If an email was sent 253290792Sgshapiro from an address to which a DSN cannot be returned and 253390792Sgshapiro in which at least one recipient address is non-deliverable, 253490792Sgshapiro then that email had been delivered in each queue run. 253590792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 253690792Sgshapiro degli Studi dell'Insubria. 253790792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 253890792Sgshapiro i.e., the corresponding code is always compiled in now. 253990792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 254090792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 254190792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 254290792Sgshapiro attempting to canonify a hostname, some broken nameservers 254390792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 254490792Sgshapiro lookups. If you want to excuse this behavior, use this new 254590792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 254690792Sgshapiro Mark Roth of the University of Illinois at 254790792Sgshapiro Urbana-Champaign. 254890792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 254990792Sgshapiro noted by Joy Latten of IBM. 255090792Sgshapiro ConnectionRateThrottle limits the number of connections per second 255190792Sgshapiro to each daemon individually, not the overall number of 255290792Sgshapiro connections. 255390792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 255490792Sgshapiro sendmail to use a default alias schema as outlined in the 255590792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 255690792Sgshapiro cf/README. 255790792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 255890792Sgshapiro the first character after the class name is not a '/' or a 255990792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 256090792Sgshapiro rest of the line will be parsed as a map lookup. This 256190792Sgshapiro allows classes to be filled via a map lookup. See op.me 256290792Sgshapiro for more syntax information. Specifically, this can be 256390792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 256490792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 256590792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 256690792Sgshapiro example). 256790792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 256890792Sgshapiro the default schema used in the above two items. 256990792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 257090792Sgshapiro warning if a program being run from a mailer or file class 257190792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 257290792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 257390792Sgshapiro if a program being run from a mailer or file class 257490792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 257590792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 257690792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 257790792Sgshapiro (without quotes) will disable this and return to the 257890792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 257990792Sgshapiro Suggested by Bryan Stansell of GNAC. 258090792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 258190792Sgshapiro HELO/EHLO commands. 258290792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 258390792Sgshapiro possible protocol family which may be used for outgoing 258490792Sgshapiro connections. Restrictions placed on one family only affect 258590792Sgshapiro outgoing connections on that particular family. Because of 258690792Sgshapiro this change, the ${client_flags} macro is not set until the 258790792Sgshapiro connection is established. Based on patch from Motonori 258890792Sgshapiro Nakamura of Kyoto University. 258990792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 259090792Sgshapiro when the -bv option is given by users who are neither root 259190792Sgshapiro nor the TrustedUser so users can not read private aliases, 259290792Sgshapiro forwards, or :include: files. It also will override the -v 259390792Sgshapiro (verbose) command line option. 259490792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 259590792Sgshapiro address can't be used for the outgoing connection, fall 259690792Sgshapiro back to the settings in ClientPortOptions (if set). 259790792Sgshapiro Problem noted by John Beck of Sun Microsystems. 259890792Sgshapiro New named config file rule check_data for DATA command (input: 259990792Sgshapiro number of recipients). Based on patch from Mark Roth of 260090792Sgshapiro the University of Illinois at Urbana-Champaign. 260190792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 260290792Sgshapiro can be specified using the '#' option character. For 260390792Sgshapiro example, 'ETRN #queuegroup'. 260490792Sgshapiro If an LDAP server times out or becomes unavailable, close the 260590792Sgshapiro current connection and reopen to get to one of the fallback 260690792Sgshapiro servers. Patch from Paul Hilchey of the University of 260790792Sgshapiro British Columbia. 260890792Sgshapiro Make default error number on $#error messages 550 instead of 501 260990792Sgshapiro because 501 is not allowed on all commands. 261090792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 261190792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 261290792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 261390792Sgshapiro if required. 261490792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 261590792Sgshapiro class instead. 261690792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 261790792Sgshapiro "IPv6:" tag to identify the address properly. For example, 261890792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 261990792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 262090792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 262190792Sgshapiro MTA is running. For example, during a queue run. 262290792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 262390792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 262490792Sgshapiro Nelson of IBM. 262590792Sgshapiro The maximum number of commands before the MTA slows down when too 262690792Sgshapiro many "light weight" commands have been received are now 262790792Sgshapiro configurable during compile time. The current values and 262890792Sgshapiro their defaults are: 262990792Sgshapiro MAXBADCOMMANDS 25 unknown commands 263090792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 263190792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 263290792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 263390792Sgshapiro MAXETRNCOMMANDS 8 ETRN 263490792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 263590792Sgshapiro Costales of SL3D, Inc. 263690792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 263790792Sgshapiro ${MyMacro} is defined but also that it is not empty. 263890792Sgshapiro Properly quote usernames with special characters if they are used 263990792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 264090792Sgshapiro Meteorological Institute. 264190792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 264290792Sgshapiro messages for messages for mailing list expanded addresses 264390792Sgshapiro which are not delivered on the initial attempt. 264490792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 264590792Sgshapiro the final dot has been sent to avoid affecting future 264690792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 264790792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 264890792Sgshapiro file systems that require to call fsync() for a directory 264990792Sgshapiro if the meta-data in it has been changed. This should be 265090792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 265190792Sgshapiro See sendmail/README for further information. 265290792Sgshapiro Avoid file locking deadlock when updating the statistics file if 265390792Sgshapiro sendmail is signaled to terminate. Problem noted by 265490792Sgshapiro Christophe Wolfhugel of France Telecom. 265590792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 265690792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 265790792Sgshapiro the Finnish Meteorological Institute. 265890792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 265990792Sgshapiro from Peter A. Friend of EarthLink. 266090792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 266190792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 266290792Sgshapiro flora.ca. 266390792Sgshapiro Portability: 266490792Sgshapiro Remove support for AIX 2, which supports only 14 character 266590792Sgshapiro filenames and is outdated anyway. Suggested by 266690792Sgshapiro Valdis Kletnieks of Virginia Tech. 266790792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 266890792Sgshapiro i.e., use default /usr/sbin, change owner/group 266990792Sgshapiro of man pages and user-executable to root/sys, set 267090792Sgshapiro optimization limit to 0 (unlimited). Based on patch 267190792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 267290792Sgshapiro Hurtta of the Finnish Meteorological Institute. 267390792Sgshapiro Do not assume LDAP support is installed by default under 267490792Sgshapiro Solaris 8 and later. 267590792Sgshapiro Add support for OpenUNIX. 267690792Sgshapiro CONFIG: Increment version number of config file to 10. 267790792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 267890792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 267990792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 268090792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 268190792Sgshapiro temporary lookup failures. 268290792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 268390792Sgshapiro action to be taken by aborting the search for domain names 268490792Sgshapiro or IP nets. 268590792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 268690792Sgshapiro relay address as long as the other part allows the email 268790792Sgshapiro to get through. 268890792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 268990792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 269090792Sgshapiro entry like user+*@domain. This allows handling of details by 269190792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 269290792Sgshapiro introduced to match only non-empty details of addresses. 269390792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 269490792Sgshapiro and hence there is no required order within the MAILER 269590792Sgshapiro section anymore except for MAILER(`uucp') which must come 269690792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 269790792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 269890792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 269990792Sgshapiro as canonical.

If sendmail needs to drop 340764562Sgshapiro these privileges and the operating system doesn't set the 340864562Sgshapiro saved-uid as well, exit with an error. Problem noted by 340964562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 341064562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 341164562Sgshapiro it populates. It is possible that some broken 341264562Sgshapiro implementations of snprintf() exist that do not do this. 341364562Sgshapiro Systems in this category should compile with 341464562Sgshapiro -DSNPRINTF_IS_BROKEN=1.

Problem 341764562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 341864562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 341964562Sgshapiro Implementation influenced by the example programs of 342064562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 342164562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 342264562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 342364562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 342464562Sgshapiro cf/README and doc/op/op.*. 342564562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 342664562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 342764562Sgshapiro ${server_name}, and ${server_addr}. These are documented 342864562Sgshapiro in cf/README and doc/op/op.*. 342964562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 343064562Sgshapiro random data. 343164562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 343264562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 343364562Sgshapiro try to use STARTTLS despite the security problems. 343464562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 343564562Sgshapiro support encryption. Based on code contributed by Tim 343664562Sgshapiro Martin of CMU. 343764562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 343864562Sgshapiro strength factor. 343964562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 344064562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 344164562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 344264562Sgshapiro of CMU. 344364562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 344464562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 344564562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 344664562Sgshapiro Fix the default family selection for DaemonPortOptions. As 344764562Sgshapiro documented, unless a family is specified in a 344864562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 344964562Sgshapiro also the default if no DaemonPortOptions value is set. 345064562Sgshapiro Therefore, IPv6 users should configure additional sockets 345164562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 345264562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 345364562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 345464562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 345564562Sgshapiro the interface information for an outgoing connection. 345664562Sgshapiro Not doing so was creating a mismatch between the socket 345764562Sgshapiro family and address used in subsequent connections if the 345864562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 345964562Sgshapiro by John Beck of Sun Microsystems. 346064562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 346164562Sgshapiro family based on the IP address. ${if_family} is no longer 346264562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 346364562Sgshapiro of Sun Microsystems. 346464562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 346564562Sgshapiro macros for both the incoming interface address/family and 346664562Sgshapiro the outgoing interface address/family. In order for M=b 346764562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 346864562Sgshapiro the incoming information in the queue file for later 346964562Sgshapiro delivery attempts. 347064562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 347164562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 347264562Sgshapiro smoe.org. 347364562Sgshapiro Add more vigilance in checking for putc() errors on output streams 347464562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 347564562Sgshapiro noted by Graeme Hewson of Oracle. 347664562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 347764562Sgshapiro Problem noted by Ajay Matia. 347864562Sgshapiro Under certain circumstances, an address could be listed as deferred 347964562Sgshapiro but would be bounced back to the sender as failed to be 348064562Sgshapiro delivered when it really should have been queued. Problem 348164562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 348264562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 348364562Sgshapiro the SMTP transaction out of sync.

Problem noted by Neil Rickert 348864562Sgshapiro of Northern Illinois University. 348964562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 349064562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 349164562Sgshapiro Convert the free disk space shown in a control socket status query 349264562Sgshapiro to kilobyte units. 349364562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 349464562Sgshapiro looking up the hostname, requeue the message for a later 349564562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 349664562Sgshapiro Polytechnic. 349764562Sgshapiro Under the proper circumstances, failed connections would be recorded 349864562Sgshapiro as "Bad file number" instead of "Connection failed" in the 349964562Sgshapiro queue file and persistent host status. Problem noted by 350064562Sgshapiro Graeme Hewson of Oracle. 350164562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 350264562Sgshapiro within the hoststatus directory (e.g., lost+found). 350364562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 350464562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 350564562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 350664562Sgshapiro If a message data file can't be opened at delivery time, panic and 350764562Sgshapiro abort the attempt instead of delivering a message that 350864562Sgshapiro states "<<< No Message Collected >>>". 350964562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 351064562Sgshapiro restrictive.

Problem noted 351864562Sgshapiro by Valdis Kletnieks of Virginia Tech. 351964562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 352064562Sgshapiro only the first to open the connection is allowed to close 352164562Sgshapiro it so a later map close doesn't break the connection for 352264562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 352364562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 352464562Sgshapiro authentication.

Problem noted by Michal Zalewski of the 377864562Sgshapiro "Internet for Schools" project (IdS). 377964562Sgshapiro SECURITY: There is a potential for a denial of service attack if 378064562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 378164562Sgshapiro sendmail process while it is rebuilding the aliases file 378264562Sgshapiro (leaving it in an inconsistent state). This option and 378364562Sgshapiro its use is deprecated and will be removed from a future 378464562Sgshapiro version of sendmail. 378564562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 378664562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 378764562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 378864562Sgshapiro (IdS). 378964562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 379064562Sgshapiro a large number of files. See cf/README for more details. 379164562Sgshapiro The directory structure of the distribution has changed slightly 379264562Sgshapiro for easier code sharing among the programs. 379364562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 379464562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 379564562Sgshapiro which hold the client's authentication credentials, 379664562Sgshapiro the mechanism used for authentication, and the 379764562Sgshapiro authorization identity (i.e., the AUTH= parameter if 379864562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 379964562Sgshapiro On systems which use the Torek stdio library (all of the BSD 380064562Sgshapiro distributions), use memory-buffered files to reduce 380164562Sgshapiro file system overhead by not creating temporary files on 380264562Sgshapiro disk. Contributed by Exactis.com, Inc. 380364562Sgshapiro New option DataFileBufferSize to control the maximum size of a 380464562Sgshapiro memory-buffered data (df) file before a disk-based file is 380564562Sgshapiro used. Contributed by Exactis.com, Inc. 380664562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 380764562Sgshapiro memory-buffered transcript (xf) file before a disk-based 380864562Sgshapiro file is used. Contributed by Exactis.com, Inc. 380964562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 381064562Sgshapiro now listen on several different ports. Use: 381164562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 381264562Sgshapiro to run a Message Submission Agent (MSA); this is turned 381364562Sgshapiro on by default in m4-generated .cf files; it can be turned 381464562Sgshapiro off with FEATURE(`no_default_msa'). 381564562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 381664562Sgshapiro begin using RFC 2476 Message Submission for initial user 381764562Sgshapiro message submission. XUSR may disappear from a future release. 381864562Sgshapiro The new '-G' (relay (gateway) submission) command line option 381964562Sgshapiro indicates that the message being submitted from the command 382064562Sgshapiro line is for relaying, not initial submission. This means 382164562Sgshapiro the message will be rejected if the addresses are not fully 382264562Sgshapiro qualified and no canonicalization will be done. Future 382364562Sgshapiro releases may even reject improperly formed messages. 382464562Sgshapiro The '-U' (initial user submission) command line option is 382564562Sgshapiro deprecated and may be removed from a future release. 382664562Sgshapiro Mail user agents should begin using '-G' to indicate that 382764562Sgshapiro this is a relay submission (the inverse of -U). 382864562Sgshapiro The next release of sendmail will assume that any message submitted 382964562Sgshapiro from the command line is an initial user submission and act 383064562Sgshapiro accordingly. 383164562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 383264562Sgshapiro program or deliver to file as the owner of that file, the 383364562Sgshapiro address is marked as unsafe. This means if RunAsUser is 383464562Sgshapiro set, users won't be able to use programs or delivery to 383564562Sgshapiro files in their .forward files. Administrators can override 383664562Sgshapiro this by setting the DontBlameSendmail option to the new 383764562Sgshapiro setting NonRootSafeAddr. 383864562Sgshapiro Allow group or world writable directories if the sticky bit is set 383964562Sgshapiro on the directory and DontBlameSendmail is set to 384064562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 384164562Sgshapiro InCert Software. 384264562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 384364562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 384464562Sgshapiro set in the DontBlameSendmail option. Requested by many. 384564562Sgshapiro New Timeout.control option to limit the total time spent satisfying 384664562Sgshapiro a control socket request. 384764562Sgshapiro New Timeout.resolver options for controlling BIND resolver 384864562Sgshapiro settings: 384964562Sgshapiro Timeout.resolver.retrans 385064562Sgshapiro Sets the resolver's retransmission time interval (in 385164562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 385264562Sgshapiro and Timeout.resolver.retrans.normal. 385364562Sgshapiro Timeout.resolver.retrans.first 385464562Sgshapiro Sets the resolver's retransmission time interval (in 385564562Sgshapiro seconds) for the first attempt to deliver a message. 385664562Sgshapiro Timeout.resolver.retrans.normal 385764562Sgshapiro Sets the resolver's retransmission time interval (in 385864562Sgshapiro seconds) for all resolver lookups except the first 385964562Sgshapiro delivery attempt. 386064562Sgshapiro Timeout.resolver.retry 386164562Sgshapiro Sets the number of times to retransmit a resolver 386264562Sgshapiro query. Sets both Timeout.resolver.retry.first 386364562Sgshapiro and Timeout.resolver.retry.normal. 386464562Sgshapiro Timeout.resolver.retry.first 386564562Sgshapiro Sets the number of times to retransmit a resolver 386664562Sgshapiro query for the first attempt to deliver a message. 386764562Sgshapiro Timeout.resolver.retry.normal 386864562Sgshapiro Sets the number of times to retransmit a resolver 386964562Sgshapiro query for all resolver lookups except the first 387064562Sgshapiro delivery attempt. 387164562Sgshapiro Contributed by Exactis.com, Inc. 387264562Sgshapiro Support multiple queue directories. To use multiple queues, supply 387364562Sgshapiro a QueueDirectory option value ending with an asterisk. For 387464562Sgshapiro example, /var/spool/mqueue/q* will use all of the 387564562Sgshapiro directories or symbolic links to directories beginning with 387664562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 387764562Sgshapiro mind, the queue directory structure should not be changed 387864562Sgshapiro while sendmail is running. Queue runs create a separate 387964562Sgshapiro process for running each queue unless the verbose flag is 388064562Sgshapiro given on a non-daemon queue run. New items are randomly 388164562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 388264562Sgshapiro Support different directories for qf, df, and xf queue files; if 388364562Sgshapiro subdirectories or symbolic links to directories of those names 388464562Sgshapiro exist in the queue directories, they are used for the 388564562Sgshapiro corresponding queue files. Keep in mind, the queue 388664562Sgshapiro directory structure should not be changed while sendmail is 388764562Sgshapiro running. Proposed by Mathias Koerber of Singapore 388864562Sgshapiro Telecommunications Ltd. 388964562Sgshapiro New queue file naming system which uses a filename guaranteed to be 389064562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 389164562Sgshapiro without fancy file system locking. Queued items can be 389264562Sgshapiro moved between queues easily. Contributed by Exactis.com, 389364562Sgshapiro Inc. 389464562Sgshapiro Messages which are undeliverable due to temporary address failures 389564562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 389664562Sgshapiro set. Contributed by Exactis.com, Inc. 389764562Sgshapiro New command line option '-L tag' which sets the identifier used for 389864562Sgshapiro syslog. Contributed by Exactis.com, Inc. 389964562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 390064562Sgshapiro avoids opening and reading each queue file when preparing 390164562Sgshapiro to run the queue.

Use [IPC] 392464562Sgshapiro instead. 392564562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 392664562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 392764562Sgshapiro connections), IPC (which will be deprecated in a future 392864562Sgshapiro version), and FILE (for UNIX domain socket delivery). 392964562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 393064562Sgshapiro flags. 393164562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 393264562Sgshapiro body of the original message on delivery status 393364562Sgshapiro notifications. 393464562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 393564562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 393664562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 393764562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 393864562Sgshapiro Steve Schweinhart of America Online. 393964562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 394064562Sgshapiro not be set after rulesets are defined. Suggested by 394164562Sgshapiro Mitchell Blank Jr of Exec-PC. 394264562Sgshapiro Do not report temporary failure on delivery to files. In 394364562Sgshapiro interactive delivery mode, this would result in two SMTP 394464562Sgshapiro responses after the DATA command. Problem noted by 394564562Sgshapiro Nik Conwell of Boston University. 394664562Sgshapiro Check file close when mailing to files. Problem noted by Nik 394764562Sgshapiro Conwell of Boston University. 394864562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 394964562Sgshapiro Curtis W. Hillegas of Princeton University. 395064562Sgshapiro Always bind to the LDAP server regardless of whether you are using 395164562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 395264562Sgshapiro @Home Network. 395364562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 395464562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 395564562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 395664562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 395764562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 395864562Sgshapiro similar to check_rcpt etc. 395964562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 396064562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 396164562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 396264562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 396364562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 396464562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 396564562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 396664562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 396764562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 396864562Sgshapiro the corresponding DSN parameter values. Proposed by 396964562Sgshapiro Mathias Herberts. 397064562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 397164562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 397264562Sgshapiro before the message has been collected, thereafter it holds 397364562Sgshapiro the message size as computed by sendmail (and can be used 397464562Sgshapiro in check_compat). 397564562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 397664562Sgshapiro sendmail is using instead of the value of the DeliveryMode 397764562Sgshapiro option. 397864562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 397964562Sgshapiro Drop explicit From: if same as what would be generated only if it is 398064562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 398164562Sgshapiro Write pid to file also if sendmail only processes the queue. 398264562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 398364562Sgshapiro Log "low on disk space" only when necessary. 398464562Sgshapiro New macro ${load_avg} can be used to check the current load average. 398564562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 398664562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 398764562Sgshapiro is set. 398864562Sgshapiro Flag -S for maps to specify the character which is substituted 398964562Sgshapiro for spaces (instead of the default given by O BlankSub). 399064562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 399164562Sgshapiro This flag is set by default for the host map. Based on a 399264562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 399364562Sgshapiro Open maps only on demand, not at startup. 399464562Sgshapiro Log warning about unsupported IP address families. 399564562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 399664562Sgshapiro of the sum of all headers. This can be used to prevent 399764562Sgshapiro a denial-of-service attack. 399864562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 399964562Sgshapiro headers and parameters within those headers. This option 400064562Sgshapiro is intended to protect mail user agents from buffer 400164562Sgshapiro overflow attacks. 400264562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 400364562Sgshapiro alias recursion. 400464562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 400564562Sgshapiro Map type syslog to log the key via syslogd. 400664562Sgshapiro Entries in the alias file can be continued by putting a backslash 400764562Sgshapiro directly before the newline. 400864562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 400964562Sgshapiro dead.letter file, formerly hardcoded to 401064562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 401164562Sgshapiro default), sendmail will not attempt to save to a 401264562Sgshapiro system-wide dead.letter file if it can not bounce the mail 401364562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 401464562Sgshapiro file as it has in the past when the dead.letter file 401564562Sgshapiro could not be opened. 401664562Sgshapiro New option PidFile to define the location of the pid file. The 401764562Sgshapiro value of this option is macro expanded. 401864562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 401964562Sgshapiro process title shown in 'ps' listings. 402064562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 402164562Sgshapiro (along with the already existing macros): 402264562Sgshapiro ${daemon_info} Daemon information, e.g. 402364562Sgshapiro SMTP+queueing@00:30:00 402464562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 402564562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 402664562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 402764562Sgshapiro ${daemon_port} Daemon port, e.g., 25 402864562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 402964562Sgshapiro New macros especially for virtual hosting: 403064562Sgshapiro ${if_name} hostname of interface of incoming connection. 403164562Sgshapiro ${if_addr} address of interface of incoming connection. 403264562Sgshapiro The latter is only set if the interface does not belong to the 403364562Sgshapiro loopback net. 403464562Sgshapiro If a message being accepted via a method other than SMTP and 403564562Sgshapiro would be rejected by a header check, do not send the message. 403664562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 403764562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 403864562Sgshapiro Provide header value as quoted string in the macro 403964562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 404064562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 404164562Sgshapiro The length of the header value is stored in ${hdrlen}. 404264562Sgshapiro H*: allows to specify a default ruleset for header checks. This 404364562Sgshapiro ruleset will only be called if the individual header does 404464562Sgshapiro not have its own ruleset assigned. Suggested by Jan 404564562Sgshapiro Krueger of Unix-AG of University of Hannover. 404664562Sgshapiro The name of the header field stored in ${hdr_name}. 404764562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 404864562Sgshapiro removed if the config file version is greater than or equal 404964562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 405064562Sgshapiro input "token (1)" but does not match "token". 405164562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 405264562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 405364562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 405464562Sgshapiro Ericsson. 405564562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 405664562Sgshapiro messages with 8-bit text in headers. Problem noted by 405764562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 405864562Sgshapiro of Ericsson. 405964562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 406064562Sgshapiro modified database map file. Problem noted by Chris Adams 406164562Sgshapiro of Renaissance Internet Services. 406264562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 406364562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 406464562Sgshapiro queue up the message instead of bouncing it. 406564562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 406664562Sgshapiro standard does not provide any indication of what to do when 406764562Sgshapiro something other than 250 is received. Based on a patch 406864562Sgshapiro from Steve Schweinhart of America Online. 406964562Sgshapiro New option TrustedUser allows to specify a user who can own 407064562Sgshapiro important files instead of root. This requires HASFCHOWN. 407164562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 407264562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 407364562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 407464562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 407564562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 407664562Sgshapiro $? tests also whether the macro is non-null. 407764562Sgshapiro Print an error message if a mailer definition contains an invalid 407864562Sgshapiro equate name. 407964562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 408064562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 408164562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 408264562Sgshapiro mailer to return after sending all data to it. 408364562Sgshapiro Only free memory from the process list when adding a new process 408464562Sgshapiro into a previously filled slot. Previously, the memory was 408564562Sgshapiro freed at removal time. Since removal can happen in a 408664562Sgshapiro signal handler, this may leave the memory map in an 408764562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 408864562Sgshapiro David Cooley of Colby College. 408964562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 409064562Sgshapiro local users in the passwd file. The UserDB code has 409164562Sgshapiro already decided the message will be passed to another host 409264562Sgshapiro for processing. Fix from Tony Landells of Burdett 409364562Sgshapiro Buckeridge Young Limited. 409464562Sgshapiro Support LDAP authorization via either a file containing the 409564562Sgshapiro password or Kerberos V4 using the new map options 409664562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 409764562Sgshapiro distinguished_name is who to login as. The method can be 409864562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 409964562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 410064562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 410164562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 410264562Sgshapiro of Stanford University. 410364562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 410464562Sgshapiro deprecated and will be removed in a future version. 410564562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 410664562Sgshapiro and the map has the column delimiter set, it turns that 410764562Sgshapiro response into a delimiter separated string. The LDAP map 410864562Sgshapiro will traverse multiple entries as well. LDAP alias maps 410964562Sgshapiro automatically set the column delimiter to the comma. 411064562Sgshapiro Based on patch from Booker Bense of Stanford University and 411164562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 411264562Sgshapiro Support return of multiple values for a single LDAP lookup. The 411364562Sgshapiro values to be returned should be in a comma separated string. 411464562Sgshapiro For example, `-v "email,emailother"'. Patch from 411564562Sgshapiro Curtis W. Hillegas of Princeton University. 411664562Sgshapiro Allow the use of LDAP for alias maps. 411764562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 411864562Sgshapiro attributes found in the match will be returned. 411964562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 412064562Sgshapiro breaking up a single entry into multiple entries. This is 412164562Sgshapiro needed for LDAP alias file specifications to allow for 412264562Sgshapiro comma separated key and value strings. 412364562Sgshapiro Keep connections to LDAP server open instead of opening and closing 412464562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 412564562Sgshapiro connections such that multiple maps which use the same 412664562Sgshapiro host, port, bind DN, and authentication will only result in 412764562Sgshapiro a single connection to that host. 412864562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 412964562Sgshapiro Be more careful about checking for errors and freeing memory on 413064562Sgshapiro LDAP lookups. 413164562Sgshapiro Use asynchronous LDAP searches to save memory and network 413264562Sgshapiro resources. 413364562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 413464562Sgshapiro Increase portability to the Netscape LDAP libraries. 413564562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 413664562Sgshapiro replaced with the literal contents of the map lookup key -- 413764562Sgshapiro note that this means a lookup can be done using the LDAP 413864562Sgshapiro special characters. The new '%0' token can be used instead 413964562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 414064562Sgshapiro For example, if the LDAP map specification contains '-k 414164562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 414264562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 414364562Sgshapiro user attribute. Instead, if the LDAP map specification 414464562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 414564562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 414664562Sgshapiro with the name "*". 414764562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 414864562Sgshapiro more than one is returned, it is equivalent to no records 414964562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 415064562Sgshapiro alias dereference option; "-Z size" limits the number of 415164562Sgshapiro matches to return. 415264562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 415364562Sgshapiro LDAP maps. The value should only contain LDAP specific 415464562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 415564562Sgshapiro settings will be used for all LDAP maps unless they are 415664562Sgshapiro specified in the individual map specification ('K' 415764562Sgshapiro command). This option should be set before any LDAP maps 415864562Sgshapiro are defined. 415964562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 416064562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 416164562Sgshapiro Tech. 416264562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 416364562Sgshapiro particular, class entries get much smaller, which can be 416464562Sgshapiro important if you have large classes. 416564562Sgshapiro On network-related temporary failures, record the hostname which 416664562Sgshapiro gave error in the queued status message. Requested by 416764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 416864562Sgshapiro Add new F=% mailer flag to allow for a store and forward 416964562Sgshapiro configuration. Mailers which have this flag will not attempt 417071345Sgshapiro delivery on initial receipt of a message or on queue runs 417164562Sgshapiro unless the queued message is selected using one of the 417264562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 417364562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 417464562Sgshapiro New option ControlSocketName which, when set, creates a daemon 417564562Sgshapiro control socket. This socket allows an external program to 417664562Sgshapiro control and query status from the running sendmail daemon 417764562Sgshapiro via a named socket, similar to the ctlinnd interface to the 417864562Sgshapiro INN news server. Access to this interface is controlled by 417964562Sgshapiro the UNIX file permissions on the named socket on most UNIX 418064562Sgshapiro systems (see sendmail/README for more information). An 418164562Sgshapiro example control program is provided as contrib/smcontrol.pl. 418264562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 418364562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 418464562Sgshapiro number of processors online on the system (if that can be 418564562Sgshapiro determined). For single processor machines, this change 418664562Sgshapiro has no effect. 418764562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 418864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 418964562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 419064562Sgshapiro Motonori Nakamura of Kyoto University. 419164562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 419264562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 419364562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 419464562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 419564562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 419664562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 419764562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 419864562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 419964562Sgshapiro connection-based denial of service attacks. 420064562Sgshapiro Log basic information about authenticated connections at LogLevel 420164562Sgshapiro 10 or higher. 420264562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 420364562Sgshapiro information (from= syslog line). 420464562Sgshapiro Log the DSN code for each recipient if one is available as a new 420564562Sgshapiro equate (dsn=). 420664562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 4207120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 4208120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 4209120256Sgshapiro of the University of Illinois at Urbana-Champaign. 421064562Sgshapiro Detect temporary lookup failures in the host map if looking up a 421164562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 421264562Sgshapiro Finnish Meteorological Institute. 421364562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 421464562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 421564562Sgshapiro When a forward file points to an alias which runs a program, run 421664562Sgshapiro the program as the default user and the default group, not 421764562Sgshapiro the forward file user. This change also assures the 421864562Sgshapiro :include: directives in aliases are also processed using 421964562Sgshapiro the default user and group. Problem noted by Sergiu 422064562Sgshapiro Popovici of DNT Romania. 422164562Sgshapiro Prevent attempts to save a dead.letter file for a user with 422264562Sgshapiro no home directory (/no/such/directory).

If some of the recipients were rejected, it is 422964562Sgshapiro helpful to know the sender of the message. 423064562Sgshapiro Check the root directory (/) when checking a path for safety. 423164562Sgshapiro Problem noted by John Beck of Sun Microsystems. 423264562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 423364562Sgshapiro interactive and delivering to an alias which resolves to 423464562Sgshapiro multiple files. 423564562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 423664562Sgshapiro greater (see below); the help function doesn't print the 423764562Sgshapiro version of sendmail any longer, instead it is placed in 423864562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 423964562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 424064562Sgshapiro skipped and a version line (#vers) is introduced. The 424164562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 424264562Sgshapiro version is found, a warning is logged. The '#vers' 424364562Sgshapiro directive should be placed at the top of the help file. 424464562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 424564562Sgshapiro disk succeeded. Suggested by Nick Christenson. 424664562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 424764562Sgshapiro length before the attempt. 424864562Sgshapiro If a forward points to a filename for delivery, change to the 424964562Sgshapiro user's uid before checking permissions on the file. This 425064562Sgshapiro allows delivery to files on NFS mounted directories where 425164562Sgshapiro root is remapped to nobody. Problem noted by Harald 425264562Sgshapiro Daeubler of Universitaet Ulm. 425364562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 425464562Sgshapiro host status files, not all files. 425564562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 425664562Sgshapiro in the queue file for the message and set when delivery 425764562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 425864562Sgshapiro Wonderworks Inc. 425964562Sgshapiro Add support for storing information between rulesets using the new 426064562Sgshapiro macro map class. This can be used to store information 426164562Sgshapiro between queue runs as well using $={persistentMacros}. 426264562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 426364562Sgshapiro of Hannover. 426464562Sgshapiro New map class arith to allow for computations in rules. The 426564562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 426664562Sgshapiro as key. The two operands are specified as arguments; the 426764562Sgshapiro lookup returns the result of the computation. For example, 426864562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 426964562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 427064562Sgshapiro Add new syntax for header declarations which decide whether to 427164562Sgshapiro include the header based on a macro rather than a mailer 427264562Sgshapiro flag: 427364562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 427464562Sgshapiro This should be used along with $={persistentMacros}. 427564562Sgshapiro It can be used for adding headers to a message based on 427664562Sgshapiro the results of check_* and header check rulesets. 427764562Sgshapiro Allow new named config file rule check_eoh which is called after 427864562Sgshapiro all of the headers have been collected. The input to the 427964562Sgshapiro ruleset the number of headers and the size of all of the 428064562Sgshapiro headers in bytes separated by $|. This ruleset along with 428164562Sgshapiro the macro storage map can be used to correlate information 428264562Sgshapiro gathered between headers and to check for missing headers. 428364562Sgshapiro See cf/README or doc/op/op.ps for an example. 428464562Sgshapiro Change the default for the MeToo option to True to correspond 428564562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 428664562Sgshapiro option is deprecated and will be removed from a future 428764562Sgshapiro version. 428864562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 428964562Sgshapiro Change the sendmail binary default for SuperSafe to True. 429064562Sgshapiro Display ruleset names in debug and address test mode output 429164562Sgshapiro if referencing a named ruleset. 429264562Sgshapiro New mailer equate m= which will limit the number of messages 429364562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 429464562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 429564562Sgshapiro using it to sort. Now all the same domains are really run 429664562Sgshapiro through the queue together. If they have the same MX host, 429764562Sgshapiro then they will have a much better opportunity to use the 429864562Sgshapiro connection cache if available. This should be a reasonable 429964562Sgshapiro performance improvement. Patch from Randall Winchester of 430064562Sgshapiro the University of Maryland. 430164562Sgshapiro If a message is rejected by a header check ruleset, log who would 430264562Sgshapiro have received the message if it had not been rejected. 430364562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 430464562Sgshapiro queue immediately. No delivery attempt is made. 430564562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 430664562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 430764562Sgshapiro COMMANDS). 430864562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 430964562Sgshapiro but for outgoing connections. 431064562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 431164562Sgshapiro error messages and logging) and Modifiers, i.e. 431264562Sgshapiro a require authentication 431364562Sgshapiro b bind to interface through which mail has 431464562Sgshapiro been received 431564562Sgshapiro c perform hostname canonification 431664562Sgshapiro f require fully qualified hostname 431764562Sgshapiro h use name of interface for outgoing HELO 431864562Sgshapiro command 431964562Sgshapiro C don't perform hostname canonification 432064562Sgshapiro E disallow ETRN (see RFC 2476) 432164562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 432264562Sgshapiro h use name of interface for HELO command 432364562Sgshapiro The version number for queue files (qf) has been incremented to 4. 432464562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 432564562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 432664562Sgshapiro Institutes of Health. 432764562Sgshapiro If a mailer dies, print the status in decimal instead of octal 432864562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 432964562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 433064562Sgshapiro Move message priority from sender to recipient logging. Suggested by 433164562Sgshapiro Ulrich Windl of the Universitat Regensburg. 433264562Sgshapiro Add support for Berkeley DB 3.X. 433364562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 433464562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 433564562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 433664562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 433764562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 433864562Sgshapiro sub-options is set on the command line. Problem noted by 433964562Sgshapiro Graeme Hewson of Oracle. 434064562Sgshapiro Randomize equal preference MX records each time delivery is 434164562Sgshapiro attempted via a new connection to a host instead of once per 434264562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 434364562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 434464562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 434564562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 434664562Sgshapiro to hosts which have dynamically assigned names. 434764562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 434864562Sgshapiro the bounce for the same reason. If the body is not 8-bit 434964562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 435064562Sgshapiro not be included in the bounce. Problem noted by Valdis 435164562Sgshapiro Kletnieks of Virginia Tech. 435264562Sgshapiro The timeout for sending a message via SMTP has been changed from 435364562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 435464562Sgshapiro simply checks for progress on sending data every 5 minutes. 435564562Sgshapiro This will detect the inability to send information quicker 435664562Sgshapiro and reduce the number of processes simply waiting to 435764562Sgshapiro timeout. 435864562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 435964562Sgshapiro interface address structure when loading the system network 436064562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 436164562Sgshapiro Nanoteq. 436264562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 436364562Sgshapiro indicates the number of interfaces to read when probing 436464562Sgshapiro for hostnames and IP addresses for class w ($=w). The 436564562Sgshapiro default value is 512. Based on idea from Reinier 436664562Sgshapiro Bezuidenhout of Nanoteq. 436764562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 436864562Sgshapiro on load average. 436964562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 437064562Sgshapiro Northern Illinois University. 437164562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 437264562Sgshapiro envelope splitting has occurred. 437364562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 437464562Sgshapiro Luke Mewburn from RMIT University. 437564562Sgshapiro Add a "/quit" command to address test mode. 437664562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 437764562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 437864562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 437964562Sgshapiro Institute. 438064562Sgshapiro The contents of a class can now be copied to another class using 438164562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 438264562Sgshapiro the items in class $={Source} into the class $={Dest}. 438364562Sgshapiro Include original envelope's error transcript in bounces created for 438464562Sgshapiro split (owner-) envelopes to see the original errors when 438564562Sgshapiro the recipients were added. Based on fix from Motonori 438664562Sgshapiro Nakamura of Kyoto University. 438764562Sgshapiro Show reason for permanent delivery errors directly after the 438864562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 438964562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 439064562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 439164562Sgshapiro If the specification for the queue run interval (-q###) has a 439264562Sgshapiro syntax error, consider the error fatal and exit. 439364562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 439464562Sgshapiro noted by Motonori Nakamura of Kyoto University. 439564562Sgshapiro On operating systems which have setlogin(2), use it to set the 439664562Sgshapiro login name to the RunAsUserName when starting as a daemon. 439764562Sgshapiro This is for delivery to programs which use getlogin(). 439864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 439964562Sgshapiro Differentiate between "command not implemented" and "command 440064562Sgshapiro unrecognized" in the SMTP dialogue. 440164562Sgshapiro Strip returns from forward and include files.

Instead, ignore the 441264562Sgshapiro ruleset lines as well. 441364562Sgshapiro Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient 441464562Sgshapiro success DSN fields as well as duplicate entries for a 441564562Sgshapiro single address due to S5 and UserDB processing. Problems 441664562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological 441764562Sgshapiro Institute. 441864562Sgshapiro Turn off timeouts when exiting sendmail due to an interrupt signal 441964562Sgshapiro to prevent the timeout from firing during the exit process. 442064562Sgshapiro Problem noted by Michael Shapiro of Sun Microsystems. 442164562Sgshapiro Do not append @MyHostName to non-RFC822 addresses output by the EXPN 442264562Sgshapiro command or on Final-Recipient: and X-Actual-Recipient: DSN 442364562Sgshapiro headers. Non-RFC822 addresses include deliveries to 442464562Sgshapiro programs, file, DECnet, etc. 442564562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 442664562Sgshapiro spoof their return address. Based on idea from Neil Rickert 442764562Sgshapiro of Northern Illinois University and patch from Per Hedeland 442864562Sgshapiro of Ericsson. 442964562Sgshapiro Report the proper UID in the bounce message if an :include: file is 443064562Sgshapiro owned by a uid that doesn't map to a username and the 443164562Sgshapiro :include: file contains delivery to a file or program. 443264562Sgshapiro Problem noted by John Beck of Sun Microsystems. 443364562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 443464562Sgshapiro the remote server responds to the first QUIT with a 4xx 443564562Sgshapiro response code and drops the connection. This behavior was 443664562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 443764562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 443864562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 443964562Sgshapiro file is not present, the lookup failure would be marked as 444064562Sgshapiro a permanent failure instead of a temporary failure. Fix 444164562Sgshapiro from Russell King of the ARM Linux Project. 444264562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 444364562Sgshapiro instead of spaces between arguments. Problem noted by Randy 444464562Sgshapiro Wormser.

Problem noted by Per 447964562Sgshapiro Hedeland of Ericsson. 448064562Sgshapiro mailq displays unprintable characters in addresses as their octal 448164562Sgshapiro representation and a leading backslash. This avoids problems 448264562Sgshapiro with "unprintable" characters. Problem noted by Michal 448364562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 448464562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 448564562Sgshapiro one character past the limit. This would cause subsequent 448664562Sgshapiro hops to break the line again. The '!' is now placed in 448764562Sgshapiro the last column of the limit if the line needs to be broken. 448864562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 448964562Sgshapiro from Per Hedeland of Ericsson. 449064562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 449164562Sgshapiro resolver will fall back to TCP. However, some 449264562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 449364562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 449464562Sgshapiro don't fail on ANY queries. 449564562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 449664562Sgshapiro address, do not send an empty postmaster notification DSN 449764562Sgshapiro to the postmaster.

Suggested by Valdis Kletnieks of Virginia Tech. 483764562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 483864562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 483964562Sgshapiro new variable which identifies the root of the source 484064562Sgshapiro directories for all of the programs in the distribution. 484164562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 484264562Sgshapiro time. They can both still be overridden by setting the m4 484364562Sgshapiro macro. 484464562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 484564562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 484664562Sgshapiro build configurations, and places objects in obj.prefix.*/. 484764562Sgshapiro Complains as 'Build -f file' does for existing object 484864562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 484964562Sgshapiro Corporation. 485064562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 485164562Sgshapiro manual pages in the directory tree specified by 485264562Sgshapiro confMANROOTMAN. 485364562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 485464562Sgshapiro preformatted pages from the distribution. The new variable 485564562Sgshapiro confCOPY specifies the copying program. 485664562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 485764562Sgshapiro question. Suggested by Terry Lambert of Whistle 485864562Sgshapiro Communications. 485964562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 486064562Sgshapiro of the installed statistics and help files, respectively. 486164562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 486264562Sgshapiro operating system identity. Problem noted by Erik 486364562Sgshapiro Wachtenheim of Dartmouth College. 486464562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 486564562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 486664562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 486764562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 486864562Sgshapiro how to strip binaries. These are used by the new 486964562Sgshapiro install-strip target. 487064562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 487164562Sgshapiro the others (if it exists). 487264562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 487364562Sgshapiro then the default ones. 487490792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 487564562Sgshapiro as local delivery agent without LMTP mode, use 487664562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 487764562Sgshapiro to set the S flag. 487864562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 487964562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 488064562Sgshapiro Northern Illinois University. 488164562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 488264562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 488364562Sgshapiro the Finnish Meteorological Institute. 488464562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 488564562Sgshapiro MAILLOCK when compiling. Also requires linking with 488664562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 488764562Sgshapiro University. 488864562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 488964562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 489064562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 489164562Sgshapiro University. 489264562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 489364562Sgshapiro structure to the beginning of the program. This ensures that 489464562Sgshapiro the getservbyname() is done before any seteuid to a possibly 489564562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 489664562Sgshapiro on a Solaris system, this avoids syslog messages such as, 489764562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 489864562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 489964562Sgshapiro University. 490064562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 490164562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 490264562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 490364562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 490464562Sgshapiro characters (in LMTP mode), mail.local split the incoming 490564562Sgshapiro line up into 2046-character output lines (excluding the 490664562Sgshapiro newline). If an input line was 2047 characters long 490764562Sgshapiro (excluding CR-LF) and the last character was a '.', 490864562Sgshapiro mail.local saw it as the end of input, transfered it to the 490964562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 491064562Sgshapiro If the message was much longer, both sendmail and 491164562Sgshapiro mail.local would deadlock waiting for each other to read 491264562Sgshapiro what they have written. Problem noted by Peter Jeremy of 491364562Sgshapiro Alcatel Australia Limited. 491464562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 491564562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 491664562Sgshapiro Neil Rickert of Northern Illinois University. 491764562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 491864562Sgshapiro timeout to avoid starvation. 491964562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 492064562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 492164562Sgshapiro Infinite Monkeys & Co. 492264562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 492364562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 492464562Sgshapiro printed in a machine readable fashion and the stats file 492564562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 492664562Sgshapiro of Maryland. 492764562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 492864562Sgshapiro generated maps to the TrustedUser as specified in the 492964562Sgshapiro sendmail configuration file. 493064562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 493164562Sgshapiro configuration file to use for finding the TrustedUser 493264562Sgshapiro option. 493364562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 493464562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 493564562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 493664562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 493764562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 493864562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 493964562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 494064562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 494164562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 494264562Sgshapiro Corporation UK. 494364562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 494464562Sgshapiro (e.g., sendmail would not drop root privileges if the 494564562Sgshapiro option was specified on the command line). Problem noted 494664562Sgshapiro by Todd C. Miller of Courtesan Consulting. 494764562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 494864562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 494964562Sgshapiro Institute for Global Communications. 495064562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 495164562Sgshapiro alias file(s) if the -f option is not used. Patch from 495264562Sgshapiro John Beck of Sun Microsystems. 495364562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 495464562Sgshapiro configuration file to use for finding alias file(s). Patch 495564562Sgshapiro from John Beck of Sun Microsystems. 495664562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 495764562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 495864562Sgshapiro of the Institute for Global Communications. 495964562Sgshapiro SMRSH: Update README for the new Build system. From Tim Pierce 496064562Sgshapiro of RootsWeb Genealogical Data Cooperative. 496164562Sgshapiro VACATION: Added vacation auto-responder to sendmail distribution. 496264562Sgshapiro LIBSMDB: Added abstracted database library. Works with Berkeley 496364562Sgshapiro DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM. 496464562Sgshapiro Changed Files: 496564562Sgshapiro The Build script in the various program subdirectories are 496664562Sgshapiro no longer symbolic links. They are now scripts 496764562Sgshapiro which execute the actual Build script in 496864562Sgshapiro devtools/bin. 496964562Sgshapiro All the manual pages are now written against -man and not 497064562Sgshapiro -mandoc as they were previously. 497164562Sgshapiro Add a simple Makefile to every directory so make instead 497264562Sgshapiro of Build will work (unless parameters are 497364562Sgshapiro required for Build). 497464562Sgshapiro New Directories: 497564562Sgshapiro devtools/M4/UNIX 497664562Sgshapiro include 497764562Sgshapiro libmilter 497864562Sgshapiro libsmdb 497964562Sgshapiro libsmutil 498064562Sgshapiro vacation 498164562Sgshapiro Renamed Directories: 498264562Sgshapiro BuildTools => devtools 498364562Sgshapiro src => sendmail 498464562Sgshapiro Deleted Files: 498564562Sgshapiro cf/m4/nullrelay.m4 498664562Sgshapiro devtools/OS/Linux.ppc 498764562Sgshapiro devtools/OS/ReliantUNIX 498864562Sgshapiro devtools/OS/SINIX 498964562Sgshapiro sendmail/ldap_map.h 499064562Sgshapiro New Files: 499164562Sgshapiro INSTALL 499264562Sgshapiro PGPKEYS 499364562Sgshapiro cf/cf/generic-linux.cf 499464562Sgshapiro cf/cf/generic-linux.mc 499564562Sgshapiro cf/feature/delay_checks.m4 499664562Sgshapiro cf/feature/dnsbl.m4 499764562Sgshapiro cf/feature/generics_entire_domain.m4 499864562Sgshapiro cf/feature/no_default_msa.m4 499964562Sgshapiro cf/feature/relay_mail_from.m4 500064562Sgshapiro cf/feature/virtuser_entire_domain.m4 500164562Sgshapiro cf/mailer/qpage.m4 500264562Sgshapiro cf/ostype/bsdi.m4 500364562Sgshapiro cf/ostype/hpux11.m4 500464562Sgshapiro cf/ostype/openbsd.m4 500564562Sgshapiro contrib/bounce-resender.pl 500664562Sgshapiro contrib/domainmap.m4 500764562Sgshapiro contrib/qtool.8 500864562Sgshapiro contrib/qtool.pl 500964562Sgshapiro devtools/M4/depend/AIX.m4 501064562Sgshapiro devtools/M4/list.m4 501164562Sgshapiro devtools/M4/string.m4 501264562Sgshapiro devtools/M4/subst_ext.m4 501364562Sgshapiro devtools/M4/switch.m4 501464562Sgshapiro devtools/OS/Darwin 501564562Sgshapiro devtools/OS/GNU 501664562Sgshapiro devtools/OS/SINIX.5.43 501764562Sgshapiro devtools/OS/SINIX.5.44 501864562Sgshapiro devtools/OS/m88k 501964562Sgshapiro devtools/bin/find_in_path.sh 502064562Sgshapiro mail.local/Makefile 502164562Sgshapiro mailstats/Makefile 502264562Sgshapiro makemap/Makefile 502364562Sgshapiro praliases/Makefile 502464562Sgshapiro rmail/Makefile 502564562Sgshapiro sendmail/Makefile 502664562Sgshapiro sendmail/bf.h 502764562Sgshapiro sendmail/bf_portable.c 502864562Sgshapiro sendmail/bf_portable.h 502964562Sgshapiro sendmail/bf_torek.c 503064562Sgshapiro sendmail/bf_torek.h 503164562Sgshapiro sendmail/shmticklib.c 503264562Sgshapiro sendmail/statusd_shm.h 503364562Sgshapiro sendmail/timers.c 503464562Sgshapiro sendmail/timers.h 503564562Sgshapiro smrsh/Makefile 503664562Sgshapiro vacation/Makefile 503764562Sgshapiro Renamed Files: 503864562Sgshapiro cf/ostype/gnuhurd.m4 => cf/ostype/gnu.m4 503964562Sgshapiro sendmail/cdefs.h => include/sendmail/cdefs.h 504064562Sgshapiro sendmail/sendmail.hf => sendmail/helpfile 504164562Sgshapiro sendmail/mailstats.h => include/sendmail/mailstats.h 504264562Sgshapiro sendmail/pathnames.h => include/sendmail/pathnames.h 504364562Sgshapiro sendmail/safefile.c => libsmutil/safefile.c 504464562Sgshapiro sendmail/snprintf.c => libsmutil/snprintf.c 504564562Sgshapiro sendmail/useful.h => include/sendmail/useful.h 504664562Sgshapiro cf/ostype/solaris2.m4 => cf/ostype/solaris2.pre5.m4 504764562Sgshapiro Copied Files: 504864562Sgshapiro cf/ostype/solaris2.ml.m4 => cf/ostype/solaris2.m4 504964562Sgshapiro 505064562Sgshapiro8.9.3/8.9.3 1999/02/04 505143730Speter SECURITY: Limit message headers to a maximum of 32K bytes (total 505243730Speter of all headers in a single message) to prevent a denial of 505343730Speter service attack.

This can be used to help prevent relaying. 549238032Speter Patch from Mitchell Blank Jr of Exec-PC. 549338032Speter Mark failures for the *file* mailer and return bounce messages to the 549438032Speter sender for those failures. 549538032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 549638032Speter preserving the TZ environment variable until TimeZoneSpec 549738032Speter has been determined. Problem noted by Ralf Hildebrandt of 549838032Speter Technical University of Braunschweig. Patch from Per Hedeland 549938032Speter of Ericsson. 550038032Speter Print test input in address test mode when input is not from the tty 550164562Sgshapiro when the -v flag is given (i.e., sendmail -bt -v) to make 550238032Speter output easier to decipher. Problem noted by Aidan Nichol 550338032Speter of Procter & Gamble. 550438032Speter The LDAP map -s flag was not properly parsed and the error message 550564562Sgshapiro given included the remainder of the arguments instead of 550638032Speter solely the argument in error. Problem noted by Aidan Nichol 550738032Speter of Procter & Gamble. 550838032Speter New DontBlameSendmail option. This option allows administrators to 550938032Speter bypass some of sendmail's file security checks at the expense 551038032Speter of system security. This should only be used if you are 551138032Speter absolutely sure you know the consequences. The available 551238032Speter DontBlameSendmail options are: 551338032Speter Safe 551438032Speter AssumeSafeChown 551538032Speter ClassFileInUnsafeDirPath 551638032Speter ErrorHeaderInUnsafeDirPath 551738032Speter GroupWritableDirPathSafe 551838032Speter GroupWritableForwardFileSafe 551938032Speter GroupWritableIncludeFileSafe 552038032Speter GroupWritableAliasFile 552138032Speter HelpFileinUnsafeDirPath 552238032Speter WorldWritableAliasFile 552338032Speter ForwardFileInGroupWritableDirPath 552438032Speter IncludeFileInGroupWritableDirPath 552538032Speter ForwardFileInUnsafeDirPath 552638032Speter IncludeFileInUnsafeDirPath 552738032Speter ForwardFileInUnsafeDirPathSafe 552838032Speter IncludeFileInUnsafeDirPathSafe 552938032Speter MapInUnsafeDirPath 553038032Speter LinkedAliasFileInWritableDir 553138032Speter LinkedClassFileInWritableDir 553238032Speter LinkedForwardFileInWritableDir 553338032Speter LinkedIncludeFileInWritableDir 553438032Speter LinkedMapInWritableDir 553538032Speter LinkedServiceSwitchFileInWritableDir 553638032Speter FileDeliveryToHardLink 553738032Speter FileDeliveryToSymLink 553838032Speter WriteMapToHardLink 553938032Speter WriteMapToSymLink 554038032Speter WriteStatsToHardLink 554138032Speter WriteStatsToSymLink 554238032Speter RunProgramInUnsafeDirPath 554338032Speter RunWritableProgram 554438032Speter New DontProbeInterfaces option to turn off the inclusion of all the 554538032Speter interface names in $=w on startup. In particular, if you 554638032Speter have lots of virtual interfaces, this option will speed up 554738032Speter startup. However, unless you make other arrangements, mail 554838032Speter sent to those addresses will be bounced. 554938032Speter Automatically create alias databases if they don't exist and 555038032Speter AutoRebuildAliases is set. 555138032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 555238032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 555338032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 555438032Speter When determining the client host name ($&{client_name} macro), do 555538032Speter a forward (A) DNS lookup on the result of the PTR lookup 555638032Speter and compare results. If they differ or if the PTR lookup 555738032Speter fails, &{client_name} will contain the IP address 555864562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 555938032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 556038032Speter (i.e, it is like -ax for the temporary failure case, in 556138032Speter contrast to the success case). 556238032Speter New syntax to do limited checking of header syntax. A config line 556338032Speter of the form: 556438032Speter HHeader: $>Ruleset 556538032Speter causes the indicated Ruleset to be invoked on the Header 556638032Speter when read. This ruleset works like the check_* rulesets -- 556738032Speter that is, it can reject mail on the basis of the contents. 556838032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 556938032Speter from hiding their connection information in Received: 557038032Speter headers. 557138032Speter When SingleThreadDelivery is active, deliveries to locked hosts 557238032Speter are skipped. This will cause the delivering process to 557338032Speter try the next MX host or queue the message if no other MX 557438032Speter hosts are available. Suggested by Alexander Litvin. 557538032Speter The [FILE] mailer type now delivers to the file specified in the 557638032Speter A= equate of the mailer definition instead of $u. It also 557738032Speter obeys all of the F= mailer flags such as the MIME 557838032Speter 7/8 bit conversion flags. This is useful for defining 557938032Speter a mailer which delivers to the same file regardless of the 558064562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 558138032Speter Do not assume the identity of a remote connection is root@localhost 558238032Speter if the remote connection closes the socket before the 558338032Speter remote identity can be queried. 558438032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 558538032Speter Some mailers, including procmail, require that the real 558638032Speter uid is left unchanged by sendmail. Problem noted by Per 558738032Speter Hedeland of Ericsson. 558838032Speter No longer is the src/obj*/Makefile selected from a large list -- it 558938032Speter is now generated using the information in BuildTools/OS/ -- 559038032Speter some of the details are determined dynamically via 559138032Speter BuildTools/bin/configure.sh. 559238032Speter The other programs in the sendmail distribution -- mail.local, 559338032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 559438032Speter the new Build method which creates an operating system 559538032Speter specific Makefile using the information in BuildTools. 559638032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 559738032Speter a failure on one message won't affect future messages to the 559838032Speter same host). This is necessary if the remote host sends 559938032Speter a 451 error if the domain of the sender does not resolve 560038032Speter as is common in anti-spam configurations. Problem noted 560138032Speter by Mitchell Blank Jr of Exec-PC. 560238032Speter New "discard" mailer for check_* rulesets and header checking 560338032Speter rulesets. If one of the above rulesets resolves to the 560438032Speter $#discard mailer, the commands will be accepted but the 560538032Speter message will be completely discarded after it is accepting. 560638032Speter This means that even if only one of the recipients 560738032Speter resolves to the $#discard mailer, none of the recipients 560838032Speter will receive the mail. Suggested by Brian Kantor. 560938032Speter All but the last cloned envelope of a split envelope were queued 561038032Speter instead of being delivered. Problem noted by John Caruso 561138032Speter of CNET: The Computer Network. 561238032Speter Fix deadlock situation in persistent host status file locking. 561338032Speter Syslog an error if a user forward file could not be read due to 561438032Speter an error. Patch from John Beck of Sun Microsystems. 561538032Speter Use the first name returned on machine lookups when canonifying a 561638032Speter hostname via NetInfo. Patch from Timm Wetzel of GWDG. 561738032Speter Clear the $&{client_addr}, $&{client_name}, and $&{client_port} 561838032Speter macros when delivering a bounce message to prevent 561938032Speter rejection by a check_compat ruleset which uses these macros. 562038032Speter Problem noted by Jens Hamisch of AgiX Internetservices GmbH. 562138032Speter If the check_relay ruleset resolves to the the error mailer, the 562238032Speter error in the $: portion of the resolved triplet is used 562338032Speter in the rejection message given to the remote machine. 562438032Speter Suggested by Scott Gifford of The Internet Ramp. 562538032Speter Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros 562638032Speter before calling the check_relay ruleset. Suggested by Scott 562738032Speter Gifford of The Internet Ramp. 562838032Speter Sendmail would get a segmentation fault if a mailer exited with an 562938032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 563038032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 563138032Speter Institute. 563238032Speter Separate snprintf/vsnprintf routines into separate file for use by 563338032Speter mail.local. 563438032Speter Allow multiple map lookups on right hand side, e.g., 563538032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 563638032Speter Christophe Wolfhugel of the Pasteur Institute. 563738032Speter Properly generate success DSN messages if requested for aliases 563838032Speter which have owner- aliases. Problem noted by Kari Hurtta 563938032Speter of the Finnish Meteorological Institute. 564038032Speter Properly display delayed-expansion macros ($&{macroname}) in 564138032Speter address test mode (-bt). Problem noted by Bryan Costales 564238032Speter of InfoBeat, Inc. 564338032Speter -qR could sometimes match names incorrectly. Problem noted by 564438032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 564538032Speter Include a magic number and version in the StatusFile for the 564638032Speter mailstats command. 564738032Speter Record the number of rejected and discarded messages in the 564838032Speter StatusFile for display by the mailstats command. Patch 564938032Speter from Randall Winchester of the University of Maryland. 565038032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 565138032Speter user portion as IDENT:username@site instead of 565238032Speter username@site to differentiate the two.

Patch from Per Hedeland of 565538032Speter Ericsson. 565638032Speter Change persistent host status filename substitution so '/' is 565738032Speter replaced by ':' instead of '|' to avoid clashes. Also 565838032Speter avoid clashes with hostnames with leading dots. Fix from 565938032Speter Mitchell Blank Jr. of Exec-PC. 566038032Speter If the system lock table is full, only attempt to create a new 566138032Speter queue entry five times before giving up. Previously, it 566238032Speter was attempted indefinitely which could cause the partition 566338032Speter to run out of inodes. Problem noted by Suzie Weigand of 566438032Speter Stratus Computer, Inc. 566538032Speter In verbose mode, warn if the sendmail.cf version is less than the 566638032Speter currently supported version. 566738032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 566838032Speter from Randall S.

Patch from 571438032Speter Robert Harker of Harker Systems. 571538032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 571638032Speter directory for certain programs. 571738032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 571838032Speter local mail delivery. By the default, /usr/libexec/mail.local 571938032Speter is used. This is expected to be the mail.local shipped 572038032Speter with 8.9 which is LMTP capable. The path is based on the 572138032Speter new confEBINDIR m4 variable. 572238032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 572338032Speter FEATURE(smrsh).

To obtain the 572538032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 572638032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 572738032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 572838032Speter the user to setup different .forward files for 572938032Speter user+detail addressing. 573038032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 573138032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 573238032Speter DontProbeInterfaces, and DontBlameSendmail options. 573338032Speter CONFIG: by default do not allow relaying (that is, accepting mail 573438032Speter from outside your domain and sending it to another host 573538032Speter outside your domain). 573638032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 573738032Speter any site to any site. 573838032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 573938032Speter domain as defined by the 'm' class ($=m) to relay. 574038032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 574138032Speter the MX records of the host portion of an incoming recipient. 574238032Speter CONFIG: new FEATURE(access_db) which turns on the access database 574377349Sgshapiro feature. This database gives you the ability to allow 574438032Speter or refuse to accept mail from specified domains for 574538032Speter administrative reasons. By default, names that are listed 574638032Speter as "OK" in the access db are domain names, not host names. 574738032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 574838032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 574938032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 575038032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 575138032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 575238032Speter of FEATURE(access_db) and class 'R' to lookup individual 575338032Speter host names only. 575438032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 575538032Speter using % addressing is used, e.g. user%site@othersite, 575638032Speter and othersite is in class 'R', the check_rcpt ruleset 575738032Speter will strip @othersite and recheck user@site for relaying. 575838032Speter This feature changes that behavior. It should not be 575938032Speter needed for most installations. 576038032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 576138032Speter domain portion of the mail sender is a local host. This 576238032Speter should only be used if absolutely necessary as it opens 576338032Speter a window for spammers. Patch from Randall S. Winchester of 576438032Speter the University of Maryland. 576538032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 576638032Speter block incoming mail destined for certain recipient 576738032Speter usernames, hostnames, or addresses. 576838032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 576938032Speter refused if the host part of the argument to MAIL FROM: cannot 577038032Speter be located in the host name service (e.g., DNS). 577138032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 577238032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 577338032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 577438032Speter MAIL FROM: senders which do not include a domain. 577538032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 577638032Speter Realtime Blackhole List.

Problem noted by Kari Hurtta of the Finnish 592438032Speter Meteorological Institute. 592538032Speter If /usr/tmp/dead.letter already existed, sendmail could not 592638032Speter add additional bounces to it. Problem noted by Thomas J. 592738032Speter Arseneault of SRI International. 592838032Speter If an SMTP mailer used a non-standard port number for the outgoing 592938032Speter connection, it would be displayed incorrectly in verbose mode. 593038032Speter Problem noted by John Kennedy of Cal State University, Chico. 593138032Speter Log the ETRN parameter specified by the client before altering them 593238032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 593338032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 593438032Speter User unknown with bogus delay= values. Change them to log 593538032Speter the same as compliant addresses. Problem noted by Kari E. 593638032Speter Hurtta of the Finnish Meteorological Institute. 593738032Speter Ignore the debug resolver option unless using sendmail debug trace 593838032Speter option for resolver. Problem noted by Greg Nichols of Wind 593938032Speter River Systems. 594038032Speter If SingleThreadDelivery was enabled and the remote server returned a 594138032Speter protocol error on the DATA command, the connection would be 594238032Speter closed but the persistent host status file would not be 594338032Speter unlocked so other sendmail processes could not deliver to 594438032Speter that host. Problem noted by Peter Wemm of DIALix. 594538032Speter If queueing up a message due to an expensive mailer, don't increment 594638032Speter the number of delivery attempts or set the last delivery 594738032Speter attempt time so the message will be delivered on the next 594838032Speter queue run regardless of MinQueueAge. Problem noted by 594938032Speter Brian J. Coan of the Institute for Global Communications. 595038032Speter Authentication warnings of "Processed from queue _directory_" and 595138032Speter "Processed by _username_ with -C _filename_" would be logged 595238032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 595338032Speter of the Finnish Meteorological Institute. 595438032Speter Use a better heuristic for detecting GDBM. 595538032Speter Log null connections on dropped connections. Problem noted by 595638032Speter Jon Lewis of Florida Digital Turnpike. 595738032Speter If class dbm maps are rebuilt, sendmail will now detect this and 595838032Speter reopen the map. Previously, they could give stale 595938032Speter results during a single message processing (but would 596038032Speter recover when the next message was received). Fix from 596138032Speter Joe Pruett of Q7 Enterprises. 596238032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 596338032Speter requests. Problem noted by Kari E. Hurtta of the 596438032Speter Finnish Meteorological Institute. 596538032Speter Do not send a bounce message back to the sender regarding bad 596638032Speter recipients if the SMTP connection is dropped before the 596738032Speter message is accepted. Problem noted by Kari E. Hurtta of the 596838032Speter Finnish Meteorological Institute. 596938032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 597038032Speter sendmail via a UNIX pipe. This will allow rulesets using 597138032Speter $&{client_name} to process without sending the string through 597238032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 597338032Speter A combination of deferred delivery mode, a double bounce situation, 597438032Speter and the inability to save a bounce message to 597538032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 597638032Speter to postmaster but not remove the offending envelope from the 597738032Speter queue causing it to create a new bounce message each time the 597838032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 597938032Speter Associates. 598038032Speter Remove newlines from hostname information returned via DNS. There are 598138032Speter no known security implications of newlines in hostnames as 598238032Speter sendmail filters newlines in all vital areas; however, this 598338032Speter could cause confusing error messages. 598438032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 598538032Speter rejected if any of the specified addresses were bad. This 598638032Speter behavior was modified to only reject the bad addresses and not 598738032Speter the entire message. Problem noted by Jozsef Hollosi of 598838032Speter SuperNet, Inc. 598938032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 599038032Speter Bryan Costales of InfoBeat, Inc. 599138032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 599238032Speter mailers. Problem noted by Kari E. Hurtta of the 599338032Speter Finnish Meteorological Institute. 599438032Speter An error in calculating the available space in the list of addresses 599538032Speter for logging deliveries could cause an address to be silently 599638032Speter dropped. 599738032Speter Include the initial user environment if sendmail is restarted via 599838032Speter a HUP signal. This will give room for the process title. 599938032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 600038032Speter Mail could be delivered without a body if the machine does not 600138032Speter support flock locking and runs out of processes during 600238032Speter delivery. Fix from Chuck Lever of the University of Michigan. 600338032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 600438032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 600538032Speter Institute. 600638032Speter Make sure non-rebuildable database maps are opened before the 600764562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 600838032Speter are needed for verifying the left hand side of the aliases. 600938032Speter Problem noted by Lloyd Parkes of Victoria University. 601038032Speter Make sure sender RFC822 source route addresses are alias expanded for 601138032Speter bounce messages. Problem noted by Juergen Georgi of 601238032Speter RUS University of Stuttgart. 601338032Speter Minor lint fixes. 601438032Speter Return a temporary error instead of a permanent error if an LDAP map 601538032Speter search returns an error. This will allow sequenced maps which 601638032Speter use other LDAP servers to be checked. Fix from Booker Bense 601738032Speter of Stanford University. 601838032Speter When automatically converting from quoted printable to 8bit text do 601938032Speter not pad bare linefeeds with a space. Problem noted by Theo 602038032Speter Nolte of the University of Technology Aachen, Germany. 602138032Speter Portability: 602238032Speter Non-standard C compilers may have had a problem compiling 602338032Speter conf.c due to a standard C external declaration of 602438032Speter setproctitle(). Problem noted by Ted Roberts of 602538032Speter Electronic Data Systems. 602638032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 602738032Speter Jagielski of jaguNET Access Services. 602838032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 602938032Speter Digital UNIX: Digital UNIX (and possibly others) moves 603038032Speter loader environment variables into the loader memory 603138032Speter area. If one of these environment variables (such as 603238032Speter LD_LIBRARY_PATH) was the last environment variable, 603338032Speter an invalid memory address would be used by the process 603438032Speter title routine causing memory corruption. Problem 603538032Speter noted by Sam Hartman of Mesa Internet Systems. 603638032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 603738032Speter chownsafe() to always return 0 even if the OS does 603838032Speter not permit file giveaways. Problem noted by 603938032Speter Yasutaka Sumi of The University of Tokyo. 604064562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 604138032Speter Gerald Rinske of Siemens Business Services VAS. 604238032Speter Linux: Pad process title with NULLs. Problem noted by 604338032Speter Jon Lewis of Florida Digital Turnpike. 604438032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 604538032Speter incorrect value for the number of interfaces. 604638032Speter Problem noted by Chris Loelke of JetStream Internet 604738032Speter Services. 604838032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 604938032Speter Rinske of Siemens Business Services VAS. 605038032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 605138032Speter used on a Solaris machine. Problem noted by 605238032Speter Stephen Ma of Jtec Pty Limited. 605338032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 605438032Speter Services VAS. 605538032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 605638032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 605738032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 605838032Speter Ericsson. 605938032Speter 606064562Sgshapiro8.8.7/8.8.7 1997/08/03 606138032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 606238032Speter an exclusive lock already set -- i.e., almost all systems 606338032Speter except 4.4-BSD derived systems), the initial attempt at 606438032Speter rebuilding aliases file if the database didn't already 606538032Speter exist would fail. Patch from Raymund Will of LST Software 606638032Speter GmbH. 606738032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 606838032Speter Problem noted by Fredrik J�nsson of the Royal Institute 606938032Speter of Technology, Stockholm. 607038032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 607138032Speter some environments could give "multiple definitions" for these 607238032Speter routines during compilation. If using TCP Wrappers, assume 607338032Speter that these routines are included as though they were in the 607438032Speter C library. Patch from Robert La Ferla. 607538032Speter When a NEWDB database map was rebuilt at the same time it was being 607638032Speter used by a queue run, the maps could be left locked for the 607738032Speter duration of the queue run, causing other processes to hang. 607838032Speter Problem noted by Kendall Libby of Shore.NET. 607938032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 608038032Speter mail was passed on without any recipient header. This could 608138032Speter cause problems downstream. Problem noted by Xander Jansen 608238032Speter of SURFnet ExpertiseCentrum. 608338032Speter Give error when GDBM is used with sendmail. GDBM's locking and 608438032Speter linking of the .dir and .pag files interferes with sendmail's 608538032Speter locking and security checks. Problems noted by Fyodor 608638032Speter Yarochkin of the Kyrgyz Republic FreeNet. 608738032Speter Don't fsync qf files if SuperSafe option is not set. 608838032Speter Avoid extra calls to gethostbyname for addresses for which a 608938032Speter gethostbyaddr found no value. Also, ignore any returns 609038032Speter from gethostbyaddr that look like a dotted quad. 609138032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 609238032Speter "may be forged", since at the network level we pretty much 609338032Speter have to assume that the information is good. 609438032Speter In some cases, errors during an SMTP session could leave files 609538032Speter open or locked. 609638032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 609790792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 609838032Speter errors during testing. 609938032Speter Errors in file locking of NEWDB maps had the incorrect file name 610038032Speter printed in the error message. 610138032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 610238032Speter missing parameter were issued, the EHLO behaved like a HELO. 610338032Speter Load limiting never kicked in for incoming SMTP transactions if the 610443730Speter DeliveryMode=background and any recipient was an alias or 610538032Speter had a .forward file. From Nik Conwell of Boston University. 610638032Speter On some non-Posix systems, the decision of whether chown(2) permits 610738032Speter file giveaway was undefined. From Tetsu Ushijima of the 610838032Speter Tokyo Institute of Technology. 610938032Speter Fix race condition that could cause the body of a message to be 611038032Speter lost (so only the header was delivered). This only occurs 611138032Speter on systems that do not use flock(2), and only when a queue 611238032Speter runner runs during a critical section in another message 611338032Speter delivery. Based on a patch from Steve Schweinhart of 611438032Speter Results Computing. 611538032Speter If a qf file was found in a mail queue directory that had a problem 611638032Speter (wrong ownership, bad format, etc.) and the file name was 611738032Speter exactly MAXQFNAME bytes long, then instead of being tried 611838032Speter once, it would be tried on every queue run. Problem noted 611938032Speter by Bryan Costales of Mercury Mail. 612038032Speter If the system supports an st_gen field in the status structure, 612138032Speter include it when reporting that a file has changed after open. 612238032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 612338032Speter This out to be checked as well as reported, since it is 612438032Speter theoretically possible for an attacker to remove a file after 612538032Speter it is opened and replace it with another file that has the 612638032Speter same i-number, but some filesystems (notably AFS) return 612738032Speter garbage in this field, and hence always look like the file 612838032Speter has changed. As a practical matter this is not a security 612938032Speter problem, since the files can be neither hard nor soft links, 613038032Speter and on no filesystem (that I am aware of) is it possible to 613138032Speter have two files on the same filesystem with the same i-number 613238032Speter simultaneously. 613338032Speter Delete the root Makefile from the distribution -- it is only for 613438032Speter use internally, and does not work at customer sites. 613538032Speter Fix botch that caused the second MAIL FROM: command in a single 613638032Speter transaction to clear the entire transaction. Problem 613738032Speter noted by John Kennedy of Cal State University, Chico. 613838032Speter Work properly on machines that have _PATH_VARTMP defined without 613938032Speter a trailing slash. (And a pox on vendors that decide to 614038032Speter ignore the established conventions!) Problem noted by 614138032Speter Gregory Neil Shapiro of WPI. 614238032Speter Internal changes to make it easier to add another protocol family 614338032Speter (intended for IPv6). Patches are from John Kennedy of 614438032Speter CSU Chico. 614538032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 614638032Speter an extra space at the beginning of some lines. Problem 614738032Speter noted by Charles Karney of Princeton University; fix based 614838032Speter on a patch from Christophe Wolfhugel. 614938032Speter Portability: 615038032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 615138032Speter with the _Sendmail_ book, 2nd edition. Note that 615238032Speter the book is actually wrong: _PATH_SENDMAILCF should 615338032Speter be used instead. 615438032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 615538032Speter of Argonne National Laboratory. 615638032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 615738032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 615838032Speter SunOS: Include <memory.h> to fix warning from util.c. From 615938032Speter James Aldridge of EUnet Ltd. 616038032Speter Solaris: Change STDIR (location of status file) to /etc/mail 616138032Speter in Makefiles. 616238032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 616338032Speter Makefiles. Use NEWDB on Linux instead. 616438032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 616538032Speter exists but behaves differently than other OSes. 616638032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 616738032Speter around the problem. Problem noted by Tom Moore of 616838032Speter NCR Corp. 616938032Speter HP-UX 9.x: fix compile warnings for old select API.

This makes it possible to create a root 622238032Speter owned file in an arbitrary directory by inserting the symlink 622338032Speter into a writable directory after the initial lstat(2) check 622438032Speter determined that the file did not exist. The only verified 622538032Speter example of a system having these odd semantics for O_EXCL 622638032Speter and symbolic links was HP-UX prior to version 9.07. Most 622738032Speter systems do not have the problem, since a exclusive create 622838032Speter of a file disallows symbolic links. Systems that have been 622938032Speter verified to NOT have the problem include AIX 3.x, *BSD, 623038032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 623138032Speter and Ultrix. This is a potential exposure on systems that 623238032Speter have this bug and which do not have a MAILER-DAEMON alias 623338032Speter pointing at a legitimate account, since this will cause old 623438032Speter mail to be dropped in /var/tmp/dead.letter. 623538032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 623638032Speter if maps or alias files are in world writable directories. 623738032Speter If your system has alias maps in writable directories, it 623838032Speter is potentially possible for an attacker to replace the .db 623938032Speter (or .dir and .pag) files by symbolic links pointing at 624038032Speter another database; this can be used either to expose 624138032Speter information (e.g., by pointing an alias file at /etc/spwd.db 624238032Speter and probing for accounts), or as a denial-of-service attack 624338032Speter (by trashing the password database). The fix disallows 624438032Speter symbolic links entirely when rebuilding alias files or on 624538032Speter maps that are in writable directories, and always warns on 624638032Speter writable directories; 8.9 will probably consider writable 624738032Speter directories to be fatal errors. This does not represent an 624838032Speter exposure on systems that have alias files in unwritable 624938032Speter system directories. 625038032Speter SECURITY: disallow .forward or :include: files that are links (hard 625138032Speter or soft) if the parent directory (or any directory in the 625238032Speter path) is writable by anyone other than the owner. This is 625338032Speter similar to the previous case for user files. This change 625438032Speter should not affect most systems, but is necessary to prevent 625538032Speter an attacker who can write the directory from pointing such 625638032Speter files at other files that are readable only by the owner. 625738032Speter SECURITY: Tighten safechown rules: many systems will say that they 625838032Speter have a safe (restricted to root) chown even on files that 625938032Speter are mounted from another system that allows owners to give 626038032Speter away files. The new rules are very strict, trusting file 626138032Speter ownership only in those few cases where the system has 626238032Speter been verified to be at least as paranoid as necessary. 626338032Speter However, it is possible to relax the rules to partially 626438032Speter trust the ownership if the directory path is not world or 626538032Speter group writable. This might allow someone who has a legitimate 626638032Speter :include: file (referenced directly from /etc/aliases) to 626738032Speter become another non-root user if the :include: file is in a 626838032Speter non-writable directory on an NFS-mounted filesystem where 626938032Speter the local system says that giveaway is denied but it is 627038032Speter actually permitted. I believe this to be a very small set 627138032Speter of cases. If in doubt, do not point :include: aliases at 627238032Speter NFS-mounted filesystems. 627338032Speter SECURITY: When setting a numeric group id using the RunAsUser option 627438032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 627538032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 627638032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 627738032Speter The user id was still set properly. Problem noted by Uli 627838032Speter Pralle of the Technical University of Berlin. 627938032Speter Save the initial gid set for use when checking for if the 628038032Speter PrivacyOptions=restrictmailq option is set. Problem reported 628138032Speter by Wolfgang Ley of DFN-CERT. 628238032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 628338032Speter failure on one message won't affect future messages to the 628438032Speter same host). 628538032Speter IP source route printing had an "off by one" error that would 628638032Speter affect any options that came after the route option. Patch 628738032Speter from Theo de Raadt. 628838032Speter The "Message is too large" error didn't successfully bounce the error 628938032Speter back to the sender. Problem reported by Stephen More of 629038032Speter PSI; patch from Gregory Neil Shapiro of WPI. 629138032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 629238032Speter of 5.1.3); it apparently gets used in multiple ways. 629338032Speter Suggested by John Myers of Portola Communications. 629438032Speter Fix possible extra null byte generated during collection if errors 629538032Speter occur at the beginning of the stream. Patch contributed by 629638032Speter Andrey A. Chernov and Gregory Neil Shapiro. 629738032Speter Code changes to avoid possible reentrant call of malloc/free within 629838032Speter a signal handler. Problem noted by John Beck of Sun 629938032Speter Microsystems. 630038032Speter Move map initialization to be earlier so that check_relay ruleset 630138032Speter will have the latest version of the map data. Problem noted 630238032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 630338032Speter If there are fatal errors during the collection phase (e.g., message 630438032Speter too large) don't send the bogus message. 630538032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 630638032Speter have errors and have owner- aliases. Problem noted by Michael 630738032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 630838032Speter Avoid null pointer dereference on illegal Boundary= parameters in 630938032Speter multipart/mixed Content-Type: header. Problem noted by 631038032Speter Richard Muirden of RMIT University. 631138032Speter Always print error messages during newaliases (-bi) even if the 631238032Speter ErrorMode is not set to "print". Fix from Gregory Neil 631338032Speter Shapiro. 631438032Speter Test mode could core dump if you did a /map lookup in an optional map 631538032Speter that could not be opened. Based on a fix from John Beck of 631638032Speter Sun Microsystems. 631738032Speter If DNS is misconfigured so that the last MX record tried points to 631838032Speter a host that does not have an A record, but other MX records 631938032Speter pointed to something reasonable, don't bounce the message 632038032Speter with a "host unknown" error. Note that this should really 632138032Speter be fixed in the zone file for the domain. Problem noted by 632238032Speter Joe Rhett of Navigist, Inc. 632338032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 632438032Speter the message as having been tried; otherwise the next queue 632538032Speter run will not realize that this is a second attempt and will 632638032Speter retry immediately. Problem noted by Bryan Costales of 632738032Speter Mercury Mail. 632838032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 632938032Speter will be run until the later setting of the clock is reached. 633038032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 633138032Speter Morgan Stanley. 633238032Speter If the load average rises above the cutoff threshold (above which 633338032Speter sendmail will not process the queue at all) during a queue 633438032Speter run, abort the queue run immediately. Problem noted by 633538032Speter Bryan Costales of Mercury Mail. 633638032Speter The variable queue processing algorithm (based on the message size, 633738032Speter number of recipients, message precedence, and job age) was 633838032Speter non-functional -- either the entire queue was processed or 633938032Speter none of the queue was processed. The updated algorithm 634038032Speter does no queue run if a single recipient zero size job will 634138032Speter not be run. 634238032Speter If there is a fatal ("panic") message that will cause sendmail to 634338032Speter die immediately, never hold the error message for future 634438032Speter printing. 634538032Speter Force ErrorMode=print in -bt mode so that all errors are printed 634638032Speter regardless of the setting of the ErrorMode option in the 634738032Speter configuration file. Patch from Gregory Neil Shapiro. 634838032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 634938032Speter routine available in one of the libraries. Use it in conf.h. 635038032Speter The -m (match only) flag now works on host class maps. 635138032Speter If class hash or btree maps are rebuilt, sendmail will now detect 635238032Speter this and reopen the map. Previously, they could give 635338032Speter erroneous results during a single message processing 635438032Speter (but would recover when the next message was received). 635538032Speter Don't delete zero length queue files when doing queue runs until the 635638032Speter files are at least ten minutes old. This avoids a potential 635738032Speter race condition: the creator creates the qf file, getting back 635838032Speter a file descriptor. The queue runner locks it and deletes it 635938032Speter because it is zero length. The creator then writes the 636038032Speter descriptor that is now for a disconnected file, and the 636138032Speter job goes away. Based on a suggestion by Bryan Costales. 636238032Speter When determining the "validated" host name ($_ macro), do a forward 636338032Speter (A) DNS lookup on the result of the PTR lookup and compare 636438032Speter results. If they differ or if the PTR lookup fails, tag the 636538032Speter address as "may be forged". 636638032Speter Log null connections (i.e., hosts that connect but do not do any 636738032Speter substantive activity on the connection before disconnecting; 636838032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 636938032Speter Always permit "writes" to /dev/null regardless of the link count. 637038032Speter This is safe because /dev/null is special cased, and no open 637138032Speter or write is ever actually attempted. Patch from Villy Kruse 637238032Speter of TwinCom. 637338032Speter If a message cannot be sent because of a 552 (exceeded storage 637438032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 637538032Speter was given, don't return the body in the bounce, since there 637638032Speter is a very good chance that the message will double-bounce. 637738032Speter Fix possible line truncation if a quoted-printable had an =00 escape 637838032Speter in the body. Problem noted by Charles Karney of the Princeton 637938032Speter Plasma Physics Laboratory. 638038032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 638138032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 638238032Speter Institute. 638338032Speter The MaxDaemonChildren option wasn't applying to queue runs as 638438032Speter documented. Note that this increases the potential denial 638538032Speter of service problems with this option: an attacker can 638638032Speter connect many times, and thereby lock out queue runs as well 638738032Speter as incoming connections. If you use this option, you should 638838032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 638938032Speter to avoid this attack. Failure to limit noted by Matthew 639038032Speter Dillon of BEST Internet Communications. 639138032Speter Always give a message in newaliases if alias files cannot be 639238032Speter opened instead of failing silently. Suggested by Gregory 639338032Speter Neil Shapiro. This change makes the code match the O'Reilly 639438032Speter book (2nd edition). 639538032Speter Some older versions of the resolver could return with h_errno == -1 639638032Speter if no name server could be reached, causing mail to bounce 639738032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 639838032Speter John Beck of SunSoft. 639938032Speter If a :include: file is owned by a user that does not have an entry 640038032Speter in the passwd file, sendmail could dereference a null pointer. 640138032Speter Problem noted by Satish Mynam of Sun Microsystems. 640238032Speter Take precautions to make sure that the SMTP protocol cannot get out 640338032Speter of sync if (for example) an alias file cannot be opened. 640438032Speter Fix a possible race condition that can cause a SIGALRM to come in 640538032Speter immediately after a SIGHUP, causing the new sendmail to die. 640638032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 640738032Speter from Villy Kruse of TwinCom. 640838032Speter Ignore improperly formatted SMTP reply codes. Previously these were 640938032Speter partially processed, which could cause confusing error 641038032Speter returns. 641138032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 641238032Speter on some architectures. 641338032Speter Portability: 641438032Speter A/UX: from Jim Jagielski of NASA/GSFC. 641538032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 641638032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 641738032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 641838032Speter defined. Problem reported by A Sun of the University 641938032Speter of Washington. 642038032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 642138032Speter the system rather than guessing at compile time. 642238032Speter Patch contributed by John Beck of Sun Microsystems. 642338032Speter Intel Paragon: from Wendy Lin of Purdue University. 642438032Speter GNU Hurd: from Miles Bader of the GNU project. 642538032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 642638032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 642738032Speter Unfortunately releasing them opens a race condition, 642838032Speter but there appears to be no fix for this. Patch from 642938032Speter Gregory Neil Shapiro. 643038032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 643138032Speter Solaris: a bug in strcasecmp caused characters with the 643238032Speter high order bit set to apparently randomly match 643338032Speter letters -- for example, $| (0233) matches "i" and "I". 643438032Speter Problem noted by John Gregson of the University of 643538032Speter Cambridge. 643638032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 643738032Speter Kari Hurtta. 643838032Speter IRIX 6.x: Create Makefiles for systems that claim to be 643938032Speter IRIX64 but are 6.2 or higher (so use the regular 644038032Speter IRIX Makefile). 644138032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 644238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 644338032Speter CONFIG: Some canonification was still done for UUCP-like addresses 644438032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 644538032Speter Brian Candler. 644638032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 644738032Speter local names as local. Problem noted by Jeff Polk of BSDI; 644838032Speter fix provided by Gregory Neil Shapiro. 644938032Speter CONFIG: The "local:user" syntax entries in mailertables and other 645038032Speter "mailer:user" syntax locations returned an incorrect value 645138032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 645238032Speter CONFIG: Retain "+detail" information when forwarding mail to a 645338032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 645438032Speter Guenther of Gustavus Adolphus College. 645538032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 645638032Speter rules are the same as for aliasing. Based on a patch from 645738032Speter Gregory Neil Shapiro. 645838032Speter CONFIG: Break up parsing rules into several pieces; this should 645938032Speter have no functional change in this release, but makes it 646038032Speter possible to have better anti-spam rulesets in the future. 646138032Speter CONFIG: Disallow double dots in host names to avoid having the 646238032Speter HostStatusDirectory store status under the wrong name. 646338032Speter In some cases this can be used as a denial-of-service attack. 646438032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 646538032Speter Gregory Neil Shapiro. 646638032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 646738032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 646838032Speter don't include From_, and convert to 8-bit). Suggestions 646938032Speter from Kimmo Suominen and Roderick Schertler. 647064562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 647138032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 647238032Speter was specified, even when it wasn't. 647338032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 647438032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 647538032Speter "slip in" a symbolic link between the lstat(2) call and the 647638032Speter exclusive open. This is only a problem on System V derived 647738032Speter systems that allow an exclusive create on files that are 647838032Speter symbolic links pointing nowhere. 647938032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 648038032Speter not reset back to root, which on some systems would cause 648138032Speter later mailboxes to fail. Also, any partial message would 648238032Speter not be truncated, which could result in repeated deliveries. 648338032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 648438032Speter developers). 648538032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 648638032Speter change to the sendmail map code was made in 8.8.3. Problem 648738032Speter noted by Gregory Neil Shapiro. 648838032Speter MAKEMAP: Give warnings on file problems such as map files that are 648990792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 649038032Speter often run as root and hence has the potential for the same 649138032Speter sorts of problems as alias rebuilds. 649238032Speter MAKEMAP: Change compilation so that it will link properly on 649338032Speter NEXTSTEP. 649438032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 649538032Speter Accept an optional list of arguments following the server 649638032Speter name for the ETRN arguments to use (instead of $=w).

This 650038032Speter Perl script converts GECOS information in the /etc/passwd 650138032Speter file into aliases, allowing for faster access to full name 650238032Speter lookups; it is also clever about adding aliases (to root) 650338032Speter for system accounts. 650438032Speter NEW FILES: 650538032Speter src/safefile.c 650638032Speter cf/ostype/gnuhurd.m4 650738032Speter cf/ostype/irix6.m4 650838032Speter contrib/passwd-to-alias.pl 650938032Speter src/Makefiles/Makefile.IRIX64.6.1 651038032Speter src/Makefiles/Makefile.IRIX64.6.x 651138032Speter RENAMED FILES: 651238032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 651338032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 651438032Speter 651564562Sgshapiro8.8.5/8.8.5 1997/01/21 651638032Speter SECURITY: Clear out group list during startup. Without this, sendmail 651738032Speter will continue to run with the group permissions of the caller, 651838032Speter even if RunAsUser is specified. 651938032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 652038032Speter to any known attack, but it's best to be conservative. 652138032Speter Suggested by Peter Wemm of DIALix. 652238032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 652338032Speter security implications. Patch from Alex Garthwaite of the 652438032Speter University of Pennsylvania. 652538032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 652638032Speter would truncate the address after "Full". Although the -f 652738032Speter syntax is incorrect (since it is in the envelope, it 652838032Speter shouldn't have comments and full names), the failure mode 652938032Speter was unnecessarily awful. 653038032Speter Fix a possible null pointer dereference when converting 8-bit data 653138032Speter to a 7-bit format. Problem noted by Jim Hutchins of 653238032Speter Sandia National Labs and David James of British Telecom. 653338032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 653438032Speter runs. Although this really shouldn't be used (F=9 is for 653538032Speter final delivery only, and using it on an SMTP mailer makes 653638032Speter it possible for a message to be converted from 8->7->8->7 653738032Speter bits several times), it shouldn't have failed with a syserr. 653838032Speter Problem noted by Eric Hagberg of Morgan Stanley. 653938032Speter _Really_ fix the multiple :maildrop code in the user database 654038032Speter module. Patch from Roy Mongiovi of Georgia Tech. 654138032Speter Let F lines in the configuration file actually read root-only 654238032Speter files if the configuration file is safe. Based on a 654338032Speter patch from Keith Reynolds of SCO. 654438032Speter ETRN followed by QUIT would hold the connection open until the queue 654538032Speter run completed. Problem noted by Truck Lewis of TDK 654638032Speter Semiconductor Corp. 654738032Speter It turns out that despite the documentation, the TCP wrappers library 654838032Speter does _not_ log rejected connections. Do the logging ourselves. 654938032Speter Problem noted by Fletcher Mattox of the University of Texas 655038032Speter at Austin. 655138032Speter If sendmail finds a qf file in its queue directory that is an unknown 655238032Speter version (e.g., when backing out to an old version), the 655338032Speter error is reported on every queue run. Change it to only 655438032Speter give the error once (and rename the qf => Qf). Patch from 655538032Speter William A. Gianopoulos of Raytheon Company. 655638032Speter Start a new session when doing background delivery; currently it 655738032Speter ignored signals but didn't start a new signal, that caused 655838032Speter some problems if a background process tried to send mail 655938032Speter under certain circumstances. Problem noted by Eric Hagberg 656038032Speter of Morgan Stanley; fix from Kari Hurtta. 656138032Speter Simplify test for skipping a queue run to just check if the current 656238032Speter load average is >= the queueing load average. Previously 656338032Speter the check factored in some other parameters that caused it 656438032Speter to essentially never skip the queue run. Patch from Bryan 656538032Speter Costales. 656638032Speter If the SMTP server is running in "nullserver" mode (that is, it is 656738032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 656838032Speter (25) commands; this helps prevent a bad guy from putting 656938032Speter you into a tight loop as a denial-of-service attack. Based 657038032Speter on an e-mail conversation with Brad Knowles of AOL. 657138032Speter Slow down when too many "light weight" commands have been issued; 657238032Speter this helps prevent a class of denial-of-service attacks. 657338032Speter The current values and defaults are: 657438032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 657538032Speter MAXHELOCOMMANDS 3 HELO, EHLO 657638032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 657738032Speter MAXETRNCOMMANDS 8 ETRN 657838032Speter These will probably be configurable in a future release. 657938032Speter On systems that have uid_t typedefed to be an unsigned short, programs 658038032Speter that had the F=S flag and no U= equate would be invoked with 658138032Speter the real uid set to 65535 rather than being left unchanged. 658238032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 658338032Speter by Steve Hubert of the University of Washington, Seattle. 658438032Speter Mail that was Quoted-Printable encoded and had a soft line break on 658538032Speter the last line (i.e., an incomplete continuation) had the last 658638032Speter line dropped. Since this appears to be illegal it isn't 658738032Speter clear what to do with it, but flushing the last line seems 658838032Speter to be a better "fail soft" approach. Based on a patch from 658938032Speter Eric Hagberg. 659038032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 659138032Speter bogus HELO command still causes the "Polite people say HELO 659238032Speter first" error message. Problem pointed out by Chris Thomas 659338032Speter of UCLA; patch from John Beck of SunSoft. 659438032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 659571345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 659671345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 659771345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 659838032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 659938032Speter in a DATA transaction to be sticky; these can occur because 660038032Speter a message is too large, and smaller messages should still go 660138032Speter through. Problem noted by Matt Dillon of Best Internet 660238032Speter Communications. 660338032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 660438032Speter had been successfully delivered to the envelope sender. 660538032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 660638032Speter Gregory Neil Shapiro of WPI. 660738032Speter Give better diagnostics on long alias lines. Based on code contributed 660838032Speter by Patrick Gosling of the University of Cambridge. 660938032Speter Increase the number of virtual interfaces that will be probed for 661038032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 661138032Speter PORTABILITY: 661238032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 661338032Speter Toshiaki Nomura of Fujitsu Limited. 661438032Speter SunOS with LDAP support: compile problems with struct timeval. 661538032Speter Patch from Nick Cuccia of TCSI Corporation. 661638032Speter SCO: from Keith Reynolds of SCO. 661738032Speter Solaris: kstat load average computation wasn't being used. 661838032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 661938032Speter (Moscow). 662038032Speter OpenBSD: from Jason Downs of teeny.org. 662138032Speter Altos System V: from Tim Rice. 662238032Speter Solaris 2.5: from Alan Perry of SunSoft. 662338032Speter Solaris 2.6: from John Beck of SunSoft. 662438032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 662538032Speter of Pratt & Whitney <miorelli@pweh.com>. 662638032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 662738032Speter _just_right_ yet. Tweak it again. I'll omit the names 662838032Speter of the "contributors" (quantity two) in this one case. 662938032Speter As of now, NO MORE DISCUSSION about the syntax of the 663038032Speter Received: line. 663138032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 663238032Speter it never inserts that class into the output file. Fix it 663338032Speter so it will honor EXPOSED_USER but will _not_ include root 663438032Speter automatically in this class. Problem noted by Ronan KERYELL 663538032Speter of Centre de Recherche en Informatique de l'�cole Nationale 663638032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 663738032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 663838032Speter such as LUSER_RELAY. This change permits the following 663938032Speter syntaxes: ``local:'' will send to the same user on the 664038032Speter local machine (e.g., in a mailertable entry for "host", 664138032Speter ``local:'' will cause an address addressed to user@host to 664238032Speter go to user on the local machone). ``local:user'' will send 664338032Speter to the named user on the local machine. ``local:user@host'' 664438032Speter is equivalent to ``local:user'' (the host is ignored). In 664538032Speter all cases, the original user@host is passed in $@ (i.e., the 664638032Speter detail information). Inspired by a report from Michael Fuhr. 664738032Speter CONFIG: Strip quotes from the first word of an "error:" host 664838032Speter indication. This lets you set (for example) the LUSER_RELAY 664938032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 665038032Speter of the \" so that the resulting string is properly quoted. 665138032Speter Problem noted by Gregory Neil Shapiro of WPI. 665238032Speter OP.ME: documentation was inconsistent about whether sendmail did a 665338032Speter NOOP or a RSET to probe the connection (it does a RSET). 665438032Speter Inconsistency noted by Deeran Peethamparam. 665538032Speter OP.ME: insert additional blank pages so it will print properly on 665638032Speter a duplex printer. From Matthew Black of Cal State University, 665738032Speter Long Beach. 665838032Speter 665964562Sgshapiro8.8.4/8.8.4 1996/12/02 666038032Speter SECURITY: under some circumstances, an attacker could get additional 666138032Speter permissions by hard linking to files that were group 666238032Speter writable by the attacker. The solution is to disallow any 666338032Speter files that have hard links -- this will affect .forward, 666438032Speter :include:, and output files. Problem noted by Terry 666538032Speter Kyriacopoulos of Interlog Internet Services. As a 666638032Speter workaround, set UnsafeGroupWrites -- always a good idea. 666738032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 666838032Speter is, it is possible to do a denial-of-service attack on 666938032Speter MX hosts that rely on the use of the null MX list. There 667038032Speter is no danger if you have this option turned off (the default). 667138032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 667238032Speter unsafe. I know of no specific attack against this, although 667338032Speter a denial-of-service attack is probably possible, but in theory 667438032Speter you should not be able to safely tweak anything that affects 667538032Speter the permissions that are used when mail is delivered. 667638032Speter Purgestat could go into an infinite loop if one of the host status 667738032Speter directories somehow became empty. Problem noted by Roy 667838032Speter Mongiovi of Georgia Tech. 667938032Speter Processes got "lost" when counting children due to a race condition. 668038032Speter This caused "proc_list_probe: lost pid" messages to be logged. 668138032Speter Problem noted by several people. 668238032Speter On systems with System V SIGCLD child signal semantics (notably AIX 668338032Speter and HP-UX), mail transactions would print the message "451 668438032Speter SMTP-MAIL: lost child: No child processes". Problem noted 668538032Speter by several people. 668638032Speter Miscellaneous compiler warnings on picky compilers (or when setting 668738032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 668838032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 668938032Speter not be persistent between runs, since they are based on the 669038032Speter message rather than the host. Problem noted by Matt Dillon 669138032Speter of Best Internet Communications. 669238032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 669338032Speter of NCR (a.k.a., AT&T Global Information Solutions). 669438032Speter Avoid the possibility of having a child daemon run to completion 669538032Speter (including closing the SMTP socket) before the parent has 669638032Speter had a chance to close the socket; this can cause the parent 669738032Speter to hang for a long time waiting for the socket to drain. 669838032Speter Patch from Don Lewis of TDK Semiconductor. 669938032Speter If the fork() failed in a queue run, the queue runners would not be 670038032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 670138032Speter Some error conditions in ETRN could cause output without an SMTP 670238032Speter status code. Problem noted by Don Lewis. 670338032Speter Multiple :maildrop addresses in the user database didn't work properly. 670438032Speter Patch from Roy Mongiovi of Georgia Tech. 670538032Speter Add ".db" automatically onto any user database spec that does not 670638032Speter already have it; this is for consistency with makemap, the 670738032Speter K line, and the documentation. Inconsistency pointed out 670838032Speter by Roy Mongiovi. 670938032Speter Allow sendmail to be properly called in nohup mode. Patch from 671038032Speter Kyle Jones of UUNET. 671138032Speter Change ETRN to ignore but still update host status files; previously 671238032Speter it would ignore them and not save the updated status, which 671338032Speter caused stale information to be maintained. Based on a patch 671438032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 671538032Speter ETRN ignore the MinQueueAge option. 671638032Speter Patch long term host status to recover more gracefully from an empty 671738032Speter host status file condition. Patch from NAKAMURA Motonori 671838032Speter of Kyoto University. 671938032Speter Several patches to signal handling code to fix potential race 672038032Speter conditions from Don Lewis. 672138032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 672238032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 672338032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 672438032Speter compile flag; use NETINET instead. Solution based on a 672538032Speter patch from Bryan Costales. 672638032Speter PORTABILITY FIXES: 672738032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 672838032Speter /etc/security/passwd file when called as root. This 672938032Speter is very slow on some systems. To speed it up, use the 673038032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 673138032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 673238032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 673338032Speter Glicker of Burrelle's Information Service. 673438032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 673538032Speter from Makoto MATSUSHITA of Osaka University. 673638032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 673738032Speter Leeds University and SASABE Tetsuro of the University 673838032Speter of Tokyo. 673938032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 674038032Speter Services, Inc. 674138032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 674238032Speter I believe this to have only been a problem if you 674338032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 674438032Speter to stick with /etc/sendmail.cf as your One True Path. 674538032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 674638032Speter Martin Laubach of the Technischen Universit�t Wien. 674738032Speter CONFIG: change default Received: line to be multiple lines rather 674838032Speter than one long one. By popular demand. 674938032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 675038032Speter from Jerome Berkman of U.C. Berkeley. 675138032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 675238032Speter to take a very long time. Problem noted by Yoshiro YONEYA 675338032Speter of NTT Software Corporation. 675438032Speter CONTRIB: add etrn.pl, contributed by John Beck. 675538032Speter NEW FILES: 675638032Speter contrib/etrn.pl 675738032Speter 675864562Sgshapiro8.8.3/8.8.3 1996/11/17 675938032Speter SECURITY: it was possible to get a root shell by lying to sendmail 676038032Speter about argv[0] and then sending it a signal. Problem noted 676138032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 676238032Speter best-of-security list. 676338032Speter Log sendmail binary version number in "Warning: .cf version level 676438032Speter (%d) exceeds program functionality (%d) message" -- this 676538032Speter should make it clearer to people that they are running 676638032Speter the wrong binary. 676738032Speter Fix a problem that occurs when you open an SMTP connection and then 676838032Speter do one or more ETRN commands followed by a MAIL command; at 676938032Speter the end of the DATA phase sendmail would incorrectly report 677038032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 677138032Speter noted by Eric Bishop of Virginia Tech. 677238032Speter When doing text-based host canonification (typically /etc/hosts 677338032Speter lookup), a null host name would match any /etc/hosts entry 677438032Speter with space at the end of the line. Problem noted by Steve 677538032Speter Hubert of the University of Washington, Seattle. 677638032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 677738032Speter Problem reported by Tom Smith of Digital Equipment Corp. 677838032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 677938032Speter size PACKETSZ (512) is not sufficient for some nameserver 678038032Speter answers containing very many resource records. The resolver 678138032Speter may also switch to TCP and retry if it detects UDP packet 678238032Speter overflow. Also, allow for the fact that the resolver 678338032Speter routines res_query and res_search return the size of the 678438032Speter *un*truncated answer in case the supplied answer buffer it 678538032Speter not big enough to accommodate the entire answer. Patch from 678638032Speter Eric Wassenaar. 678738032Speter Improvements to MaxDaemonChildren code. If you think you have too 678838032Speter many children, probe the ones you have to verify that they 678938032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 679038032Speter Also, do this probe before growing the vector of children 679138032Speter pids; this previously caused the vector to grow indefinitely 679238032Speter due to a race condition. Problem reported by Kyle Jones of 679338032Speter UUNET. 679438032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 679538032Speter O_EXLOCK to zero; this fools the map compilation code into 679638032Speter thinking that it can avoid race conditions by locking on open. 679738032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 679838032Speter Leif Erlingsson of Data Lege. 679938032Speter Always call res_init() on startup (if compiled in, of course) to 680038032Speter allow the sendmail.cf file to tweak resolver flags; without 680138032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 680238032Speter Andrew Sun of Merrill Lynch. 680338032Speter Improvements to host status printing code. Suggested by Steve Hubert 680438032Speter of the University of Washington, Seattle. 680538032Speter Change MinQueueAge option processing to do the check for the job age 680638032Speter when reading the queue file, rather than at the end; this 680738032Speter avoids parsing the addresses, which can do DNS lookups. 680838032Speter Problem noted by John Beck of InReference, Inc. 680938032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 681038032Speter properly escaped. Problem noted by Peter Nilsson of the 681138032Speter University of Linkoping. 681238032Speter In some cases, sendmail would retain root permissions during queue 681338032Speter runs even if RunAsUser was set. Problem noted by Mark 681438032Speter Thomas of Mark G. Thomas Consulting. 681538032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 681638032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 681738032Speter the envelope, and the receiving SMTP server speaks DSN, then 681838032Speter the DSN would be both generated locally and propagated to the 681938032Speter other end. 682038032Speter The U= mailer field didn't correctly extract the group id if the 682138032Speter user id was numeric. Problem noted by Kenneth Herron of 682238032Speter MCI Telecommunications Communications. 682338032Speter If a message exceeded the fixed maximum size on input, the body of 682438032Speter the message was included in the bounce. Note that this did 682538032Speter not occur if it exceeded the maximum _output_ size. Problem 682638032Speter reported by Kyle Jones of UUNET. 682738032Speter PORTABILITY FIXES: 682838032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 682938032Speter AIX4 defines to use seteuid(2) instead, which 683038032Speter works on 4.1 as well as 4.2. Problem noted by 683138032Speter H�kan Lindholm of interAF, Sweden. 683238032Speter AIX4: use tzname[] vector to determine time zone name. 683338032Speter Patch from NAKAMURA Motonori of Kyoto University. 683438032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 683538032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 683638032Speter Solaris: kstat(3k) support for retrieving the load average. 683738032Speter This adds the LA_KSTAT definition for LA_TYPE. 683838032Speter The outline of the implementation was contributed 683938032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 684038032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 684138032Speter declaration of struct rusage at the top of conf.h; 684238032Speter change it to only be included if you are using gcc, 684338032Speter which is apparently the only compiler that requires 684438032Speter it in the first place. Problem noted by Jeff 684538032Speter Earickson of Colby College. 684638032Speter IRIX: don't default to using gcc. IRIX is a civilized 684738032Speter operating system that comes with a decent compiler 684838032Speter by default. Problem noted by Barry Bouwsma and 684938032Speter Kari Hurtta. 685038032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 685138032Speter consistency with other local mailers. Inconsistency 685238032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 685338032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 685438032Speter overhead) as part of the bestmx_is_local feature, the 685538032Speter domain part was dropped from the name. Patch from Steve 685638032Speter Hubert of the University of Washington, Seattle. 685738032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 685838032Speter end up being translated to the null host name, which would 685938032Speter return any entry in /etc/hosts that had a space at the end 686038032Speter of the line. Problem noted by Steve Hubert of the 686138032Speter University of Washington, Seattle. 686238032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 686338032Speter Polytechnic Institute. 686438032Speter MAKEMAP: tweak hash and btree parameters for better performance. 686538032Speter Patch from Matt Dillon of Best Internet Communications. 686638032Speter NEW FILES: 686738032Speter src/Makefiles/Makefile.Linux.ppc 686838032Speter cf/ostype/aix4.m4 686938032Speter cf/ostype/mklinux.m4 687038032Speter 687164562Sgshapiro8.8.2/8.8.2 1996/10/18 687238032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 687338032Speter changed the code but didn't fix the problem. 687438032Speter PORTABILITY FIXES: 687538032Speter Solaris: Don't use the system getusershell(3); it can 687638032Speter apparently corrupt the heap in some circumstances. 687738032Speter Problem found by Ken Pizzini of Spry, Inc. 687838032Speter OP.ME: document several mailer flags that were accidentally omitted 687938032Speter from this document.

Problem noted 688538032Speter by Dan Bernstein of the University of Illinois at Chicago. 688638032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 688738032Speter message could overflow a buffer if it was converted back 688838032Speter to 8 bits. This caused core dumps and has the potential 688938032Speter for a remote attack. Problem first noted by Gregory Shapiro 689038032Speter of WPI. 689138032Speter Avoid duplicate deliveries of error messages on systems that don't 689238032Speter have flock(2) support. Patch from Motonori Nakamura of 689338032Speter Kyoto University. 689438032Speter Ignore null FallBackMX (V) options. If this option is null (as 689538032Speter opposed to undefined) it can cause "null signature" syserrs 689638032Speter on illegal host names. 689738032Speter If a Base64 encoded text/plain message has no trailing newline in 689838032Speter the encoded text, conversion back to 8 bits will drop the 689938032Speter final line. Problem noted by Pierre David. 690038032Speter If running with a RunAsUser, sendmail would give bogus "cannot 690138032Speter setuid" (or seteuid, or setreuid) messages on some systems. 690238032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 690338032Speter Always print error messages in -bv mode -- previously, -bv would 690438032Speter be absolutely silent on errors if the error mode was sent 690538032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 690638032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 690738032Speter term host status. This is necessary because it is common 690838032Speter to do this when you know a host has just come back up. 690938032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 691038032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 691138032Speter University of Leicester. 691238032Speter If a service (such as NIS) is specified as the last entry in the 691338032Speter service switch, but that service is not compiled in, sendmail 691438032Speter would return a temporary failure when an entry was not found 691538032Speter in the map. This caused the message to be queued instead of 691638032Speter bouncing immediately. Problem noted by Harry Edmon of the 691738032Speter University of Washington. 691838032Speter PORTABILITY FIXES: 691938032Speter Solaris 2.3 had compilation problems in conf.c. Several 692038032Speter people pointed this out. 692138032Speter NetBSD from Charles Hannum of MIT. 692238032Speter AIX4 improvements based on info from Steve Bauer of South 692338032Speter Dakota School of Mines & Technology. 692438032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 692538032Speter Patch from Gil Kloepfer Jr. 692638032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 692738032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 692838032Speter were also in $=w. Problem noted by Zoltan Basti of 692938032Speter Softec. 693038032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 693138032Speter on a patch from Eric Hagberg of Morgan Stanley. 693238032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 693338032Speter of Stanford via Robert La Ferla. 693438032Speter 693564562Sgshapiro8.8.0/8.8.0 1996/09/26 693638032Speter Under some circumstances, Bcc: headers would not be properly 693738032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 693838032Speter Log a warning if the sendmail daemon is invoked without a full 693938032Speter pathname, which prevents "kill -1" from working. I was 694038032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 694138032Speter Fix small buffer overflow. Since the data in this buffer was not 694238032Speter read externally, there was no security problem (and in fact 694338032Speter probably wouldn't really overflow on most compilers). Pointed 694438032Speter out by KIZU takashi of Osaka University. 694538032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 694638032Speter if a FallbackMXHost was specified in the configuration file 694738032Speter -- all mail would be sent to the fallback even if the original 694838032Speter host was accessible. Pointed out by Munenari Hirayama of 694938032Speter NSC (Japan). 695038032Speter A message that didn't terminate with a newline would (sometimes) not 695138032Speter have the trailing "." added properly in the SMTP dialogue, 695238032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 695338032Speter The DaemonPortOptions suboption to bind to a particular address was 695438032Speter incorrect and nonfunctional due to a misunderstanding of the 695538032Speter semantics of binding on a passive socket. Patch from 695638032Speter NIIBE Yutaka of Mitsubishi Research Institute. 695738032Speter Increase the number of MX hosts for a single name to 100 to better 695838032Speter handle the truly huge service providers such as AOL, which 695938032Speter has 13 at the moment (and climbing). In order to avoid 696038032Speter trashing memory, the buffer for all names has only been 696138032Speter slightly increased in size, to 12.8K from 10.2K -- this means 696238032Speter that if a single name had 100 MX records, the average size 696338032Speter of those records could not exceed 128 bytes. Requested by 696438032Speter Brad Knowles of America On Line. 696538032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 696638032Speter Urged by Dan Bernstein of U.C. Berkeley. 696738032Speter Print q_statdate and q_specificity in address structure debugging 696838032Speter printout. 696938032Speter Expand MCI structure flag bits for debugging output. 697038032Speter Support IPv6-style domain literals, which can have colons between 697138032Speter square braces. 697238032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 697338032Speter this is an attempt to track down a bug that one person seems 697438032Speter to be having (it may be a Solaris bug!). 697538032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 697638032Speter this caused the NOTIFY info to sometimes be lost. Problem 697738032Speter pointed out by Claus Assmann of the 697838032Speter Christian-Albrechts-University of Kiel. 697938032Speter The statistics gathered in the sendmail.st file were too high; in 698038032Speter some cases failures (e.g., user unknown or temporary failure) 698138032Speter would count as a delivery as far as the statistics were 698238032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 698338032Speter Systems that don't have flock() would not send split envelopes in 698438032Speter the initial run. Problem pointed out by Leonard Zubkoff of 698538032Speter Dandelion Digital. 698638032Speter Move buffer overflow checking -- these primarily involve distrusting 698738032Speter results that may come from NIS and DNS. 698838032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 698938032Speter include <paths.h> and hence had the wrong pathnames for a few 699038032Speter things like /var/tmp. Reported by Matthew Green. 699138032Speter Conditions were reversed for the Priority: header, resulting in all 699238032Speter values being interpreted as non-urgent except for non-urgent, 699338032Speter which was interpreted as normal. Patch from Bryan Costales. 699438032Speter The -o (optional) flag was being ignored on hash and btree maps 699538032Speter since 8.7.2. Fix from Bryan Costales. 699638032Speter Content-Types listed in class "q" will always be encoded as 699738032Speter Quoted-Printable (or more accurately, will never be encoded 699838032Speter as base64). The class can have primary types (e.g., "text") 699938032Speter or full types (e.g., "text/plain"). Based on a suggestion by 700038032Speter Marius Olafsson of the University of Iceland. 700138032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 700238032Speter dialogue) so it can be passed to programs in mailers. 700338032Speter Define ${bodytype} to be the body type (from the -B flag or the 700438032Speter BODY= ESMTP parameter) so it can be passed to programs in 700538032Speter mailers. 700638032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 700738032Speter flag is set in the mailer descriptor. Suggested by John 700838032Speter Myers of CMU. 700938032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 701038032Speter The command takes a host name; data for that host is 701138032Speter immediately (and asynchronously) flushed. Because this shares 701238032Speter the -qR implementation, other hosts may be attempted, but 701338032Speter there should be no security implications. Implementation 701438032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 701538032Speter Add three new command line flags to pass in DSN parameters: -V envid 701638032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 701738032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 701838032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 701938032Speter that the -N flag applies to all recipients; there is no way 702038032Speter to specify per-address notifications on the command line, 702138032Speter nor is there an equivalent for the ORCPT= per-address 702238032Speter parameter. 702338032Speter Restore LogLevel option to be safe (it can only be increased); 702438032Speter apparently I went into paranoid mode between 8.6 and 8.7 702538032Speter and made it unsafe. Pointed out by Dabe Murphy of the 702638032Speter University of Maryland. 702738032Speter New logging on log level 15: all SMTP traffic. Patches from 702838032Speter Andrew Gross of San Diego Supercomputer Center. 702938032Speter NetInfo property value searching code wasn't stopping when it found 703038032Speter a match. This was causing the wrong values to be found (and 703138032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 703238032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 703338032Speter out by Bill Wisner of Electronics for Imaging that you can't 703438032Speter use the bracket address form for the MAIL_HUB macro, since 703538032Speter that causes the brackets to remain in the envelope recipient 703638032Speter address used for delivery. The simple fix (stripping off the 703738032Speter brackets in the config file) breaks the use of IP literal 703838032Speter addresses. This flag will solve that problem. 703938032Speter Add MustQuoteChars option. This is a list of characters that must 704038032Speter be quoted if they are found in the phrase part of an address 704138032Speter (that is, the full name part). The characters @,;:\()[] are 704238032Speter always in this list and cannot be removed. The default is 704338032Speter this list plus . and ' to match RFC 822. 704438032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 704538032Speter that do not include a host name for back compatibility with 704638032Speter some stupid SMTP clients. Setting this violates RFC 1123 704738032Speter section 5.2.5. 704838032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 704938032Speter rejecting connections if it has more than this many 705038032Speter outstanding children accepting mail. Note that you may 705138032Speter see more processes than this because of outgoing mail; this 705238032Speter is for incoming connections only. 705338032Speter Add ConnectionRateThrottle option. If set to a positive value, the 705438032Speter number of incoming SMTP connections that will be permitted 705538032Speter in a single second is limited to this number. Connections are 705638032Speter not refused during this time, just deferred. The intent is to 705738032Speter flatten out demand so that load average limiting can kick in. 705838032Speter It is less radical than MaxDaemonChildren, which will stop 705938032Speter accepting connections even if all the connections are idle 706038032Speter (e.g., due to connection caching). 706138032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 706238032Speter specifies how long cached information about the state of a 706338032Speter host will be kept before they are considered stale and the 706438032Speter host is retried. If you are using persistent host status 706538032Speter (i.e., the HostStatusDirectory option is set) this will apply 706638032Speter between runs; otherwise, it applies only within a single queue 706738032Speter run and hence is useful only for hosts that have large queues 706838032Speter that take a very long time to run. 706938032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 707038032Speter into being a single line even if they had newlines in them 707138032Speter when read. This is to get around a botch in Lotus Notes. 707238032Speter Text class maps were totally broken -- if you ever retrieved the last 707338032Speter item in a table it would be truncated. Problem noted by 707438032Speter Gregory Neil Shapiro of WPI. 707538032Speter Extend the lines printed by the mailq command (== the -bp flag) when 707638032Speter -v is given to 120 characters; this allows more information 707738032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 707838032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 707938032Speter this was treated as end-of-input. Problem noted by Bryan 708038032Speter Costales. 708138032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 708238032Speter to the queue file. Fix from John Hughes of Atlantic 708338032Speter Technologies, Inc. 708438032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 708538032Speter if this happens in a queue run it can cause nasty delays. 708638032Speter Problem noted by Mark Horton of AT&T. 708738032Speter If userdb entries pointed to userdb entries, and there were multiple 708838032Speter values for a given key, the database cursor would get 708938032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 709038032Speter of Georgia Tech. Fixed by reading all the values and creating 709138032Speter a comma-separated list; thus, the -v output will be somewhat 709238032Speter different for this case. 709338032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 709438032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 709538032Speter of Stanford University. 709638032Speter When envelopes were split due to aliases with owner- aliases, and 709738032Speter there was some error on one of the lists, more than one of 709838032Speter the owners would get the message. Problem pointed out by 709938032Speter Roy Mongiovi of Georgia Tech. 710038032Speter Detect excessive recursion in macro expansions, e.g., $X defined 710138032Speter in terms of $Y which is defined in terms of $X. Problem 710238032Speter noted by Bryan Costales; patch from Eric Wassenaar. 710338032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 710438032Speter some cases get trashed causing bogus From_ lines. Fix from 710538032Speter Kyle Jones of UUNET. 710638032Speter When doing load average initialization, if the nlist call for avenrun 710738032Speter failed, the second and subsequent lookups wouldn't notice 710838032Speter that fact causing bogus load averages to be returned. Noted 710938032Speter by Casper Dik of Sun Holland. 711038032Speter Fix problem with incompatibility with some versions of inet_aton that 711138032Speter have changed the return value to unsigned, so a check for an 711238032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 711338032Speter This could cause mail to addresses such as [foo.com] to bounce 711438032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 711538032Speter Pasteur Institute. 711638032Speter DSNs were inconsistent if a failure occurred during the DATA phase 711738032Speter rather than the RCPT phase: the Action: would be correct, but 711838032Speter the detailed status information would be wrong. Problem noted 711938032Speter by Bob Snyder of General Electric Company. 712038032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 712138032Speter that this is the initial MUA->MTA submission. The flag current 712238032Speter does nothing, but in future releases (when MUAs start using 712338032Speter these flags) it will probably turn on things like DNS 712438032Speter canonification. 712538032Speter Default end-of-line string (E= specification on mailer [M] lines) 712638032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 712738032Speter mailers. 712838032Speter Change the internal definition for the *file* and *include* mailers 712938032Speter to have $u in the argument vectors so that they aren't 713038032Speter misinterpreted as SMTP mailers and thus use \r\n line 713138032Speter termination. This will affect anyone who has redefined 713238032Speter either of these in their configuration file. 713338032Speter Don't assume that IDENT servers close the connection after a query; 713438032Speter responses can be newline terminated. From Terry Kennedy of 713538032Speter St. Peter's College. 713638032Speter Avoid core dumps on erroneous configuration files that have 713738032Speter $#mailer with nothing following. From Bryan Costales. 713838032Speter Avoid null pointer dereference with high debug values in unlockqueue. 713938032Speter Fix from Randy Martin of Clemson University. 714038032Speter Fix possible buffer overrun when expanding very large macros. Fix 714138032Speter from Kyle Jones of UUNET. 714238032Speter After 25 EXPN or VRFY commands, start pausing for a second before 714338032Speter processing each one. This avoids a certain form of denial 714438032Speter of service attack. Potential attack pointed out by Bryan 714538032Speter Costales. 714638032Speter Allow new named (not numbered!) config file rules to do validity 714738032Speter checking on SMTP arguments: check_mail for MAIL commands and 714838032Speter check_rcpt for RCPT commands. These rulesets can do anything 714938032Speter they want; their result is ignored unless they resolve to the 715038032Speter $#error mailer, in which case the indicated message is printed 715138032Speter and the command is rejected. Similarly, the check_compat 715238032Speter ruleset is called before delivery with "from_addr $| to_addr" 715338032Speter (the $| is a meta-symbol used to separate the two addresses); 715438032Speter it can give a "this sender can't send to this recipient" 715538032Speter notification. Note that this patch allows $| to stand alone 715638032Speter in rulesets. 715738032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 715838032Speter that have the name, IP address, and port number (respectively) 715938032Speter of the SMTP client (that is, the entity at the other end of 716038032Speter the connection. These can be used in (e.g.) check_rcpt to 716138032Speter verify that someone isn't trying to relay mail through your 716238032Speter host inappropriately. Be sure to use the deferred evaluation 716338032Speter form, for example $&{client_name}, to avoid having these bound 716438032Speter when sendmail reads the configuration file. 716538032Speter Add new config file rule check_relay to check the incoming connection 716638032Speter information. Like check_compat, it is passed the host name 716738032Speter and host address separated by $| and can reject connections 716838032Speter on that basis. 716938032Speter Allow IDA-style recursive function calls. Code contributed by Mark 717038032Speter Lovell and Paul Vixie. 717138032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 717238032Speter a virtual UUCP address using either a domain address or the $k 717338032Speter macro. Based on code contributed by Mark Lovell and Paul 717438032Speter Vixie. 717538032Speter Add Stanford LDAP map. Requires special libraries that are not 717638032Speter included with sendmail. Contributed by Booker C. Bense 717738032Speter <bbense@networking.stanford.edu>; contact him for support. 717838032Speter See also the src/READ_ME file. 717938032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 718038032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 718138032Speter only for debugging deep bits of code where it is important to 718238032Speter distinguish between the single-character metasymbol $+ and the 718338032Speter two characters $, +. 718438032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 718538032Speter debug_dumpstate. 718638032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 718738032Speter files that are group writable are considered "unsafe" -- that 718838032Speter is, programs and files referenced from such files are not 718938032Speter valid recipients. 719038032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 719138032Speter name that was not in DNS or was a domain-literal. Problem 719238032Speter noted by Tom May. 719338032Speter Change the introduction to error messages to more clearly delineate 719438032Speter permanent from temporary failures; if both existed in a 719538032Speter single message it could be confusing. Suggested by John 719638032Speter Beck of InReference, Inc. 719738032Speter The IngoreDot (i) option didn't work for lines that were terminated 719838032Speter with CRLF. Problem noted by Ted Stockwell of Secure 719938032Speter Computing Corporation. 720038032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 720138032Speter message headers. Problem reported by Matt Dillon of Best 720238032Speter Internet Communications. 720338032Speter Check for bogus characters in the 0200-0237 range; since these are 720438032Speter used internally, very strange errors can occur if those 720538032Speter characters appear in headers. Problem noted by Anders Gertz 720638032Speter of Lysator. 720738032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 720838032Speter recipient mailer has the F=9 flag set, and only works on 720938032Speter text/plain body types. Code contributed by Marius Olafsson 721038032Speter of the University of Iceland. 721138032Speter Special case "postmaster" name so that it is always treated as lower 721238032Speter case in alias files regardless of configuration settings; 721338032Speter this prevents some potential problems where "Postmaster" or 721438032Speter "POSTMASTER" might not match "postmaster". In most cases 721538032Speter this change is a no-op. 721638032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 721738032Speter Costales. 721838032Speter The -a map flag was ignored for dequote maps. Problem noted by 721938032Speter Bryan Costales. 722038032Speter Fix core dump when a lookup of a class "prog" map returns no 722138032Speter response. Patch from Bryan Costales. 722238032Speter Log instances where sendmail is deferring or rejecting connections 722338032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 722438032Speter Include port number in process title for network daemons. Suggested 722538032Speter by Kyle Jones of UUNET. 722638032Speter Send ``double bounces'' (errors that occur when sending an error 722738032Speter message) to the address indicated in the DoubleBounceAddress 722838032Speter option (default: postmaster). Previously they were always 722938032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 723038032Speter Add new mode, -bD, that acts like -bd in all respects except that 723138032Speter it runs in foreground. This is useful for using with a 723238032Speter wrapper that "watches" system services. Suggested by Kyle 723338032Speter Jones of UUNET. 723438032Speter Fix botch in spacing around (parenthesized) comments in addresses 723538032Speter when the comment comes before the address. Patch from 723638032Speter Motonori Nakamura of Kyoto University. 723738032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 723838032Speter that are being bounced to postmaster, rather than "Returned 723938032Speter mail". This permits the person who is postmaster more 724038032Speter easily determine what messages are to their role as 724138032Speter postmaster versus bounces to mail they actually sent. Based 724238032Speter on a suggestion by Motonori Nakamura. 724338032Speter Add new value "time" for QueueSortOrder option; this causes the queue 724438032Speter to be sorted strictly by the time of submission. Note that 724543730Speter this can cause very bad behavior over slow lines (because 724638032Speter large jobs will tend to delay small jobs) and on nodes with 724738032Speter heavy traffic (because old things in the queue for hosts that 724838032Speter are down delay processing of new jobs). Also, this does not 724938032Speter guarantee that jobs will be delivered in submission order 725038032Speter unless you also set DeliveryMode=queue. In general, it should 725138032Speter probably only be used on the command line, and only in 725238032Speter conjunction with -qRhost.domain. In fact, there are very few 725338032Speter cases where it should be used at all. Based on an 725438032Speter implementation by Motonori Nakamura. 725538032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 725638032Speter the same manner as other rulesets. Previously a temporary 725738032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 725838032Speter of Stanford University. 725938032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 726038032Speter 5yz (permanent failure) code. The next MX host will still be 726138032Speter tried if the connection cannot be opened in the first place 726238032Speter or if the MAIL command returns a 4yz (temporary failure) code. 726338032Speter (It's hard to know what to do here, since neither RFC 974 nor 726438032Speter RFC 1123 specify when to proceed to the next MX host.) 726538032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 726638032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 726738032Speter This causes map lookups that get a temporary failure (e.g., 726838032Speter name server failure) to _not_ defer the delivery of the 726938032Speter message. This should only be used if your configuration file 727038032Speter is prepared to do something sensible in this case. Based on 727138032Speter an idea by Gregory Shapiro of WPI. 727238032Speter Fix problem finding network interface addresses. Patch from 727338032Speter Motonori Nakamura. 727438032Speter Don't reject qf entries that are not owned by your effective uid if 727590792Sgshapiro you are not running set-user-ID; this makes management of 727680785Sgshapiro certain kinds of firewall setups difficult. Patch 727780785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 727838032Speter Add persistent host status. This keeps the information normally 727938032Speter maintained within a single queue run in disk files that are 728038032Speter shared between sendmail instances. The HostStatusDirectory 728138032Speter is the directory in which the information is maintained. If 728238032Speter not set, persistent host status is turned off. If not a full 728338032Speter pathname, it is relative to the queue directory. A common 728438032Speter value is ".hoststat". 728538032Speter There are also two new operation modes: 728638032Speter * -bh prints the status of hosts that have had recent 728738032Speter connections. 728838032Speter * -bH purges the host statuses. No attempt is made to save 728938032Speter recent status information. 729038032Speter This feature was originally written by Paul Vixie of Vixie 729138032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 729238032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 729338032Speter with my insistence that things fit cleanly into the V8 729438032Speter framework is gratefully appreciated. 729538032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 729638032Speter operate). Avoids letting two sendmails on the local machine 729764562Sgshapiro open connections to the same remote host at the same time. 729838032Speter This reduces load on the other machine, but can cause mail to 729938032Speter be delayed (for example, if one sendmail is delivering a huge 730038032Speter message, other sendmails won't be able to send even small 730138032Speter messages). Also, it requires another file descriptor (for the 730238032Speter lock file) per connection, so you may have to reduce 730338032Speter ConnectionCacheSize to avoid running out of per-process 730438032Speter file descriptors. Based on the persistent host status code 730538032Speter contributed by Paul Vixie and Mark Lovell. 730638032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 730738032Speter SafeFileEnvironment option is set. Problem noted by Bryan 730838032Speter Costales. 730938032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 731038032Speter file. Problem noted by Bryan Costales. 731138032Speter If a job was aborted using the interrupt signal (e.g., control-C from 731238032Speter the keyboard), on some occasions an empty df file would be 731338032Speter left around; these would collect in the queue directory. 731438032Speter Problem noted by Bryan Costales. 731538032Speter Change the makesendmail script to enhance the search for Makefiles 731638032Speter based on release number. For example, on SunOS 5.5.1, it will 731738032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 731838032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 731938032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 732038032Speter Webmasters. 732138032Speter When creating maps using "newaliases", always map the keys to lower 732238032Speter case when creating the map unless the -f flag is specified on 732338032Speter the map itself. Previously this was done based on the F=u 732438032Speter flag in the local mailer, which meant you could create aliases 732538032Speter that you could never access. Problem noted by Bob Wu of DEC. 732638032Speter When a job was read from the queue, the bits causing notification on 732738032Speter failure or delay were always set. This caused those 732838032Speter notifications to be sent even if NOTIFY=NEVER had been 732938032Speter specified. Problem noted by Steve Hubert of the University 733038032Speter of Washington, Seattle. 733138032Speter Add new configurable routine validate_connection (in conf.c). This 733238032Speter lets you decide if you are willing to accept traffic from 733338032Speter this host. If it returns FALSE, all SMTP commands will return 733438032Speter "550 Access denied". -DTCPWRAPPERS will include support for 733538032Speter TCP wrappers; you will need to add -lwrap to the link line. 733638032Speter (See src/READ_ME for details.) 733738032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 733838032Speter bounces. Some people seemed to think that this could be 733938032Speter confusing (even though it is true). Suggested by Motonori 734038032Speter Nakamura. 734138032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 734238032Speter user early in processing to avoid potential security problems. 734338032Speter However, this means that all .forward and :include: files must 734438032Speter be readable by that user, and all files to be written must be 734538032Speter writable by that user and all programs will be executed by that 734638032Speter user. It is also incompatible with the SafeFileEnvironment 734738032Speter option. In other words, it may not actually add much to 734838032Speter security. However, it should be useful on firewalls and other 734938032Speter places where users don't have accounts and the aliases file is 735038032Speter well constrained. 735138032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 735238032Speter only on the first attempt to delivery to an address. It could 735338032Speter be set to be lower than Timeout.connect on the principle that 735438032Speter the mail should go through quickly to responsive hosts; less 735538032Speter responsive hosts get to wait for the next queue run. 735638032Speter Fix a problem on Solaris that occasionally causes programs 735738032Speter (such as vacation) to hang with their standard input connected 735838032Speter to a UDP port. It also created some signal handling problems. 735938032Speter The problems turned out to be an interaction between vfork(2) 736038032Speter and some of the libraries, particularly NIS/NIS+. I am 736138032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 736238032Speter Change user class map to do the same matching that actual delivery 736338032Speter will do instead of just a /etc/passwd lookup. This adds 736438032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 736538032Speter The Timeout.* options are not safe -- they can be used to create a 736638032Speter denial-of-service attack. Problem noted by Christophe 736738032Speter Wolfhugel. 736843730Speter Don't send PostmasterCopy messages in the event of a "delayed" 736938032Speter notification. Suggested by Barry Bouwsma. 737038032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 737138032Speter option is set, since this disables VERB mode. Suggested 737238032Speter by John Hawkinson of MIT. 737338032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 737438032Speter by Motonori Nakamura of Kyoto University. 737538032Speter Only queue messages on transient .forward open failures if there 737643730Speter were no successful opens. The previous behavior caused it 737738032Speter to queue even if a "fall back" .forward was found. Problem 737838032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 737938032Speter and Computer Science (DISCS), NUS, Singapore. 738038032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 738138032Speter is bouncing because of a MIME error during 8->7 bit conversion; 738238032Speter the encapsulated message will bounce again, causing a loop. 738338032Speter Problem noted by Steve Hubert of the University of Washington. 738438032Speter Create xf (transcript) files using the TempFileMode option value 738538032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 738638032Speter National University of Singapore. 738738032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 738838032Speter detect cases where DefaultUid is set to something that the 738938032Speter system can't cope with. 739038032Speter PORTABILITY FIXES: 739138032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 739238032Speter Atlas International. 739338032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 739438032Speter <bicknell@ufp.org>. 739538032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 739638032Speter work on the first recipient of a message due to a 739738032Speter bug in the getpwent family.

Based on a patch from Randall 744038032Speter Winchester of the University of Maryland. 744138032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 744238032Speter Robert La Ferla of Hot Software. 744338032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 744438032Speter (where "code" is an exit status) on domains (previously 744538032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 744638032Speter Foundation. 744738032Speter CONFIG: hooks for IPv6-style domain literals. 744838032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 744938032Speter if it is undefined the AliasFile option is never set; this 745038032Speter should be transparent for most everyone. Suggested by John 745138032Speter Myers of CMU. 745238032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 745338032Speter domain listed in $=w is masqueraded. With it, only those 745438032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 745538032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 745638032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 745738032Speter hosts under those domains as well as the domain headers 745838032Speter themselves. For example, if a configuration had 745938032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 746038032Speter foo.com would be masqueraded; with it, *.foo.com would be 746138032Speter masqueraded as well. Based on an implementation by Richard 746238032Speter (Pug) Bainter of U. Texas. 746338032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 746438032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 746538032Speter Keys are user names; values are outgoing mail addresses. Yes, 746638032Speter this does overlap with the user database, and figuring out 746738032Speter just when to use which one may be tricky. Based on code 746838032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 746938032Speter from Per Hedeland of Ericsson. 747038032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 747138032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 747238032Speter Keys are either fully qualified addresses or just the host 747338032Speter part (with the @ sign). For example, a table containing: 747438032Speter info@foo.com foo-info 747538032Speter info@bar.com bar-info 747638032Speter @baz.org jane@elsewhere.net 747738032Speter would send all mail destined for info@foo.com to foo-info 747838032Speter (which is presumably an alias), mail addressed to info@bar.com 747938032Speter to bar-info, and anything addressed to anyone at baz.org will 748038032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 748138032Speter and baz.org must all be in $=w. Based on discussions with 748238032Speter a great many people. 748338032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 748438032Speter Suggested by Richard Bainter. 748538032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 748638032Speter "fax" mailer. 748738032Speter CONFIG: allow mailertable entries to resolve to local:user; this 748838032Speter passes the original user@host in to procmail-style local 748938032Speter mailers as the "detail" information to allow them to do 749038032Speter additional clever processing. From Joe Pruett of 749138032Speter Teleport Corporation. Delivery to the original user can 749238032Speter be done by specifying "local:" (with nothing after the colon). 749338032Speter CONFIG: allow any context that takes "mailer:domain" to also take 749438032Speter "mailer:user@domain" to force mailing to the given user; 749538032Speter "local:user" can also be used to do local delivery. This 749638032Speter applies on *_RELAY and in the mailertable entries. Based 749738032Speter on a suggestion by Ribert Kiessling of Easynet. 749838032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 749938032Speter limits the possible domains; this reduces the number of DNS 750038032Speter lookups required to support this feature. For example, 750138032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 750238032Speter to domains under my.site.com. Code contributed by Anthony 750338032Speter Thyssen <anthony@cit.gu.edu.au>. 750438032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 750538032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 750638032Speter of WPI. 750738032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 750838032Speter event you have to define local mailers. Suggested by 750938032Speter Gregory Shapiro of WPI. 751038032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 751138032Speter be misinterpreted as a list:...; syntax. Based on a patch by 751238032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 751338032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 751438032Speter remotely connected. The address host!user was being 751538032Speter converted to host!user@thishost instead of host!user@uurelay. 751638032Speter Problem noted by William Gianopoulos of Raytheon Company. 751738032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 751838032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 751938032Speter "User has moved"; the former wording was confusing if the 752038032Speter new address is still on the local host. Based on a suggestion 752138032Speter by Andreas Luik. 752238032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 752338032Speter However, the class is not pre-initialized to contain root. 752438032Speter Suggested by Gregory Neil Shapiro. 752538032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 752638032Speter Wolfhugel. 752738032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 752838032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 752938032Speter well: this produces a slightly different mailbox format (no 753038032Speter Content-Length: headers), file ownerships and modes are 753138032Speter different (not owned by group mail; mode 600 instead of 660), 753238032Speter and the local mailer flags will have to be tweaked (make them 753338032Speter match bsd4.4) in order to use this mailer. Patches from Paul 753438032Speter Hammann of the Missouri Research and Education Network. 753538032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 753638032Speter was a delivery error, such as if the ownership on the file 753738032Speter was wrong or the mode changed between the initial stat and 753838032Speter the open. Problem reported by William Colburn of the New 753938032Speter Mexico Institute of Mining and Technology. 754038032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 754138032Speter Costales. 754238032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 754338032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 754438032Speter honored. Fix from Michael Scott Shappe. 754538032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 754638032Speter NEW FILES: 754738032Speter src/Makefiles/Makefile.AIX.2 754838032Speter src/Makefiles/Makefile.IRIX.6.2 754938032Speter src/Makefiles/Makefile.maxion 755038032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 755138032Speter src/Makefiles/Makefile.SCO.5.x 755238032Speter src/Makefiles/Makefile.UXPDSV20 755338032Speter mailstats/mailstats.8 755438032Speter praliases/praliases.8 755538032Speter cf/cf/generic-nextstep3.3.mc 755638032Speter cf/feature/genericstable.m4 755738032Speter cf/feature/limited_masquerade.m4 755838032Speter cf/feature/masquerade_entire_domain.m4 755938032Speter cf/feature/virtusertable.m4 756038032Speter cf/ostype/aix2.m4 756138032Speter cf/ostype/altos.m4 756238032Speter cf/ostype/maxion.m4 756338032Speter cf/ostype/solaris2.ml.m4 756438032Speter cf/ostype/uxpds.m4 756538032Speter contrib/re-mqueue.pl 756638032Speter DELETED FILES: 756738032Speter src/Makefiles/Makefile.Solaris 756838032Speter contrib/xla/README 756938032Speter contrib/xla/xla.c 757038032Speter RENAMED FILES: 757138032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 757238032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 757338032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 757438032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 757538032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 757638032Speter 757764562Sgshapiro8.7.6/8.7.3 1996/09/17 757838032Speter SECURITY: It is possible to force getpwuid to fail when writing the 757938032Speter queue file, causing sendmail to fall back to running programs 758038032Speter as the default user. This is not exploitable from off-site. 758138032Speter Workarounds include using a unique user for the DefaultUser 758238032Speter (old u & g options) and using smrsh as the local shell. 758338032Speter SECURITY: fix some buffer overruns; in at least one case this allows 758438032Speter a local user to get root. This is not known to be exploitable 758538032Speter from off-site. The workaround is to disable chfn(1) commands. 758638032Speter 758764562Sgshapiro8.7.5/8.7.3 1996/03/04 758838032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 758938032Speter in some case cause connections to hang or messages to have 759038032Speter extra spaces in odd places. Patch from Eric Wassenaar; 759138032Speter reports from Eric Hall of Chiron Corporation, Stephen 759238032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 759338032Speter and others. 759438032Speter 759564562Sgshapiro8.7.4/8.7.3 1996/02/18 759638032Speter SECURITY: In some cases it was still possible for an attacker to 759738032Speter insert newlines into a queue file, thus allowing access to 759838032Speter any user (except root). 759938032Speter CONFIG: no changes -- it is not a bug that the configuration 760038032Speter version number is unchanged. 760138032Speter 760264562Sgshapiro8.7.3/8.7.3 1995/12/03 760338032Speter Fix botch in name server timeout in RCPT code; this problem caused 760438032Speter two responses in SMTP, which breaks things horribly. Fix 760538032Speter from Gregory Neil Shapiro of WPI. 760638032Speter Verify that L= value on M lines cannot be negative, which could cause 760738032Speter negative array subscripting. Not a security problem since 760838032Speter this has to be in the config file, but it could have caused 760938032Speter core dumps. Pointed out by Bryan Costales. 761038032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 761138032Speter Costales. 761238032Speter PORTABILITY FIXES: 761338032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 761438032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 761538032Speter order. Tweak it to work properly. Based on fixes 761638032Speter from Fletcher Mattox of UTexas and Betty Lee of 761738032Speter Stanford University. 761838032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 761938032Speter Deficiency pointed out by Bryan Costales of ICSI. 762038032Speter 762164562Sgshapiro8.7.2/8.7.2 1995/11/19 762238032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 762338032Speter OperatorChars, and UnixFromLine options. They were not 762438032Speter properly repaired in 8.7.1. 762538032Speter Completely delete the Bcc: header if and only if there are other 762638032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 762738032Speter last being a historic botch, of course). If Bcc: is the 762838032Speter only recipient header in the message, its value is tossed, 762943730Speter but the header name is kept. The old behavior (always keep 763038032Speter the header name and toss the value) allowed primary recipients 763138032Speter to see that a Bcc: went to _someone_. 763238032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 763338032Speter sender to <address> using -f'' syslog messages. Suggested 763438032Speter by Kari Hurtta. 763538032Speter If a sequence or switch map lookup entry gets a tempfail but then 763638032Speter continues on to another map type, but the name is not found, 763738032Speter return a temporary failure from the sequence or switch map. 763838032Speter For example, if hosts search ``dns files'' and DNS fails 763938032Speter with a tempfail, the hosts map will go on and search files, 764038032Speter but if it fails the whole thing should be a tempfail, not 764138032Speter a permanent (host unknown) failure, even though that is the 764238032Speter failure in the hosts.files map. This error caused hard 764338032Speter bounces when it should have requeued. 764438032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 764590792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 764638032Speter working properly due to excessive paranoia. Pointed out by 764738032Speter John Hawkinson of Panix. 764838032Speter An SMTP RCPT command referencing a host that gave a nameserver 764938032Speter timeout would return a 451 command (8.6 accepted it and 765043730Speter queued it locally). Revert to the 8.6 behavior in order 765138032Speter to simplify queue management for clustered systems. Suggested 765238032Speter by Gregory Neil Shapiro of WPI. The same problem could break 765338032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 765438032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 765538032Speter Infobiogen. 765638032Speter Fix possible buffer overflow in munchstring(). This was not a security 765738032Speter problem because you couldn't specify any argument to this 765838032Speter without first giving up root privileges, but it is still a 765938032Speter good idea to avoid future problems. Problem noted by John 766038032Speter Hawkinson and Sam Hartman of MIT. 766138032Speter ``452 Out of disk space for temp file'' messages weren't being 766238032Speter printed. Fix from David Perlin of Nanosoft. 766343730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 766438032Speter is not set, since this is required to get the actual DSNs 766538032Speter created. Problem pointed out by John Gardiner Myers of CMU. 766638032Speter Log permission problems that cause .forward and :include: files to 766738032Speter be untrusted or ignored on log level 12 and higher. Suggested 766838032Speter by Randy Martin of Clemson University. 766938032Speter Allow user ids in U= clauses of M lines to have hyphens and 767038032Speter underscores. 767138032Speter Fix overcounting of recipients -- only happened when sending to an 767238032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 767338032Speter of Systems and Computer Technology Corporation. 767438032Speter If a message is sent to an address that fails, the error message that 767538032Speter is returned could show some extraneous "success" information 767638032Speter included even if the user did not request success notification, 767738032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 767838032Speter Config files that had no AliasFile definition were defaulting to 767938032Speter using /etc/aliases; this caused problems with nullclient 768038032Speter configurations. Change it back to the 8.6 semantics of 768138032Speter having no local alias file unless it is declared. Problem 768238032Speter noted by Charles Karney of Princeton University. 768338032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 768438032Speter Costales of ICSI. 768538032Speter Map lookups of class "userdb" maps were always case sensitive; they 768638032Speter should be controlled by the -f flag like other maps. Pointed 768738032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 768838032Speter Fix problem that caused some addresses to be passed through ruleset 5 768938032Speter even when they were tagged as "sticky" by prefixing the 769038032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 769138032Speter Technological University. 769238032Speter When converting a message to Quoted-Printable, prevent any lines with 769338032Speter dots alone on a line by themselves. This is because of the 769438032Speter preponderance of broken mailers that still get this wrong. 769538032Speter Code contributed by Per Hedeland of Ericsson. 769638032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 769738032Speter out by Bjart Kvarme of USIT/UiO (Norway). 769838032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 769938032Speter Requested by Allan Johannesen. 770038032Speter Delete check for text format of alias files -- it should be legal 770138032Speter to have the database format of the alias files without the 770238032Speter text version. Problem pointed out by Joe Rhett of Navigist, 770338032Speter Inc. 770438032Speter If "Ot" was specified with no value, the TZ variable was not properly 770538032Speter imported from the environment. Pointed out by Frank Crawford 770638032Speter <frank@ansto.gov.au>. 770738032Speter Some architectures core dumped on "program" maps that didn't have 770838032Speter extra arguments. Patch from Booker C. Bense of Stanford 770938032Speter University. 771038032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 771138032Speter the parent should do this. Fix from Brian Coan of the 771238032Speter Association for Progressive Communications. 771338032Speter If MinQueueAge was set and a message was considered but not run 771438032Speter during a queue run and the Timeout.queuereturn interval was 771538032Speter reached, a "timed out" error message would be returned that 771638032Speter didn't include the failed address (and claimed to be a warning 771738032Speter even though it was fatal). The fix is to not return such 771838032Speter messages until they are actually tried, i.e., in the next 771938032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 772038032Speter SINTEF RUNIT, Oslo. 772138032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 772238032Speter that have the hes_getmailhost() routine.

Bug 776938032Speter pointed out by John Hawkinson of MIT. 777038032Speter Fix strange case of an executable called by a program map that 777138032Speter returns a value but also a non-zero exit status; this 777238032Speter would give contradictory results in the higher level; in 777338032Speter particular, the default clause in the map lookup would be 777438032Speter ignored. Change to ignore the value if the program returns 777538032Speter non-zero exit status. From Tom Moore of AT&T GIS. 777638032Speter Shorten parameters passed to syslog() in some contexts to avoid a 777738032Speter bug in many vendors' implementations of that routine. Although 777838032Speter this isn't really a bug in sendmail per se, and my solution 777938032Speter has to assume that syslog() has at least a 1K buffer size 778038032Speter internally (I know some vendors have shortened this 778138032Speter dramatically -- they're on their own), sendmail is a popular 778238032Speter target. Also, limit the size of %s arguments in sprintf. 778338032Speter These both have possible security implications. Solutions 778438032Speter suggested by Casper Dik of Sun's Network Security Group 778538032Speter (Holland), Mark Seiden, and others. 778638032Speter Fix a problem that might cause a non-standard -B (body type) 778738032Speter parameter to be passed to the next server with undefined 778838032Speter results. This could have security implications. 778938032Speter If a filesystem was at > 100% utilization, the freediskspace() 779038032Speter routine incorrectly returned an error rather than zero. 779138032Speter Problem noted by G. Paul Ziemba of Alantec. 779238032Speter Change MX sort order so that local hostnames (those in $=w) always 779338032Speter sort first within a given preference. This forces the bestmx 779438032Speter map to always return the local host first, if it is included 779538032Speter in the list of highest priority MX records. From K. Robert 779638032Speter Elz. 779738032Speter Avoid some possible null pointer dereferences. Fixes from Randy 779838032Speter Martin <WOLF@CLEMSON.EDU> 779938032Speter When sendmail starts up on systems that have no fully qualified 780038032Speter domain name (FQDN) anywhere in the first matching host map 780138032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 780238032Speter sendmail would sleep to try to find a FQDN, which it really 780338032Speter really needs. This has been changed to fall through to the 780438032Speter next map type if it can't find a FQDN -- i.e., if the hosts 780538032Speter file doesn't have a FQDN, it will try dns even though the 780638032Speter short name was found in /etc/hosts. This is probably a crock, 780738032Speter but many people have hosts files without FQDNs. Remember: 780838032Speter domain names are your friends. 780938032Speter Log a high-priority message if you can't find your FQDN during startup. 781038032Speter Suggested by Simon Barnes of Schlumberger Limited. 781138032Speter When using Hesiod, initialize it early to improve error reporting. 781238032Speter Patch from Don Lewis of Silicon Systems, Inc. 781338032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 781438032Speter connection timeout in the kernel. Add a new "connect" timeout 781538032Speter to limit this time. Defaults to zero (use whatever the 781638032Speter kernel provides). Based on code contributed by J.R. Oldroyd 781738032Speter of TerraNet. 781838032Speter Under some circumstances, a failed message would not be properly 781938032Speter removed from the queue, causing tons of bogus error messages. 782038032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 782138032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 782238032Speter of WPI. 782338032Speter PORTABILITY FIXES: 782438032Speter On IRIX 5.x, there was an inconsistency in the setting 782538032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 784138032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 784238032Speter otherwise the F=S causes the From_ line to imply that root is 784338032Speter the sender. Problem pointed out by Claude Scarpelli of 784438032Speter Infobiogen (France). 784538032Speter NEW FILES: 784638032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 784738032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 784838032Speter src/Makefiles/Makefile.UXPDS 784938032Speter 785064562Sgshapiro8.7/8.7 1995/09/16 785138032Speter Fix a problem that could cause sendmail to run out of file 785238032Speter descriptors due to a trashed data structure after a 785338032Speter vfork.

This was used "safely" in the sense 785938032Speter that it only did a stat, but it would have set the 786038032Speter map modification time improperly. Problem pointed out 786138032Speter by Roy Mongiovi of Georgia Tech. 786238032Speter Clean up the Subject: line on warning messages and return 786338032Speter receipts so that they don't say "Returned mail:"; this 786438032Speter can be confusing. 786538032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 786638032Speter useful enough to make it worthwhile printing on "-d". 786738032Speter Avoid logging alias statistics every time you read the alias 786838032Speter file on systems with no database method compiled in. 786938032Speter If you have a name with a trailing dot, and you try looking it 787038032Speter up using gethostbyname without the dot (for /etc/hosts 787138032Speter compatibility), be sure to turn off RES_DEFNAMES and 787238032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 787338032Speter Problem noted by Charles Amos of the University of 787438032Speter Maryland. 787538032Speter Don't do timeouts in collect if you are not running SMTP. 787638032Speter There is nothing that says you can't have a long 787738032Speter running program piped into sendmail (possibly via 787838032Speter /bin/mail, which just execs sendmail). Problem reported 787938032Speter by Don "Truck" Lewis of Silicon Systems. 788038032Speter Try gethostbyname() even if the DNS lookup fails iff option I 788138032Speter is not set. This allows you to have hosts listed in 788238032Speter NIS or /etc/hosts that are not known to DNS. It's normally 788338032Speter a bad idea, but can be useful on firewall machines. This 788438032Speter should really be broken out on a separate flag, I suppose. 788538032Speter Avoid compile warnings against BIND 4.9.3, which uses function 788638032Speter prototypes.

From Kyle Jones of UUNET. 789138032Speter SECURITY: avoid denial-of-service attacks possible by destroying 789238032Speter the alias database file by setting resource limits low. 789338032Speter This involves adding two new compile-time options: 789438032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 789538032Speter available) and HASULIMIT (indicating that ulimit(2) support 789638032Speter is available -- the Release 3 form is used). The former 789738032Speter is assumed on BSD-based systems, the latter on System 789838032Speter V-based systems. Attack noted by Phil Brandenberger of 789938032Speter Swarthmore University. 790038032Speter New syntaxes in test (-bt) mode: 790138032Speter ``.Dmvalue'' will define macro "m" to "value". 790238032Speter ``.Ccvalue'' will add "value" to class "c". 790338032Speter ``=Sruleset'' will dump the contents of the indicated 790438032Speter ruleset. 790538032Speter ``=M'' will display the known mailers. 790638032Speter ``-ddebug-spec'' is equivalent to the command-line 790738032Speter -d debug flag. 790838032Speter ``$m'' will print the value of macro $m. 790938032Speter ``$=c'' will print the contents of class $=c. 791038032Speter ``/mx host'' returns the MX records for ``host''. 791138032Speter ``/parse address'' will parse address, returning the value of 791238032Speter crackaddr (essentially, the comment information) 791338032Speter and the parsed address. 791438032Speter ``/try mailer address'' will rewrite address into the form 791538032Speter it will have when presented to the indicated mailer. 791638032Speter ``/tryflags flags'' will set flags used by parsing. The 791738032Speter flags can be `H' for header or `E' for envelope, 791838032Speter and `S' for sender or `R' for recipient. These 791938032Speter can be combined, so `HR' sets flags for header 792038032Speter recipients. 792138032Speter ``/canon hostname'' will try to canonify hostname and 792238032Speter return the result. 792338032Speter ``/map mapname key'' will look up `key' in the indicated 792438032Speter `mapname' and return the result. 792538032Speter Somewhat better handling of UNIX-domain socket addresses -- it 792638032Speter should show the pathname rather than hex bytes. 792738032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 792838032Speter the header for envelope sender information and uses 792938032Speter CR-LF as message terminators. It was thought to be 793038032Speter obsolete (used only for Arpanet NCP protocols), but it 793138032Speter turns out that the UK ``Grey Book'' protocols require 793238032Speter that functionality. 793338032Speter Fix a fix in previous release -- if gethostname and gethostbyname 793438032Speter return a name without dots, and if an attempt to canonify 793538032Speter that name fails, wait one minute and try again. This can 793638032Speter result in an extra 60 second delay on startup if your system 793738032Speter hostname (as returned by hostname(1)) has no dot and no names 793838032Speter listed in /etc/hosts or your NIS map have a dot. 793938032Speter Check for proper domain name on HELO and EHLO commands per 794038032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 794138032Speter of Michigan Technological University. 794238032Speter Relax chownsafe rules slightly -- old version said that if you 794338032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 794438032Speter if fpathconf returned EINVAL or ENOSYS), assume that 794538032Speter chown is not safe. The new version falls back to whether 794638032Speter you are on a BSD system or not. This is important for 794738032Speter SunOS, which apparently always returns one of those 794838032Speter error codes. This impacts whether you can mail to files 794938032Speter or not. 795038032Speter Syntax errors such as unbalanced parentheses in the configuration 795138032Speter file could be omitted if you had "Oem" prior to the 795238032Speter syntax error in the config file. Change to always print 795338032Speter the error message. It was especially weird because it 795438032Speter would cause a "warning" message to be sent to the Postmaster 795538032Speter for every message sent (but with no transcript). Problem 795638032Speter noted by Gregory Paris of Motorola. 795738032Speter Rewrite collect and putbody to handle full 8-bit data, including 795838032Speter zero bytes.

This is to handle the 802738032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 802838032Speter assume that ``group name:'' is a comment on the first 802938032Speter address and the ``;'' is a comment on the last address). 803038032Speter This requires config file support to get right. It does 803138032Speter understand that :: is NOT this syntax, and can be turned 803238032Speter off completely by setting the ColonOkInAddresses option. 803338032Speter Level 6 config files added with new mailer flags: 803438032Speter A Addresses are aliasable. 803538032Speter i Do udb rewriting on envelope as well as header 803638032Speter sender lines. Applies to the from address mailer 803738032Speter flags rather than the recipient mailer flags. 803838032Speter j Do udb rewriting on header recipient addresses. 803938032Speter Applies to the sender mailer flags rather than the 804038032Speter recipient mailer flags. 804138032Speter k Disable check for loops when doing HELO command. 804238032Speter o Always run as the mail recipient, even on local 804338032Speter delivery. 804438032Speter w Check for an /etc/passwd entry for this user. 804538032Speter 5 Pass addresses through ruleset 5. 804638032Speter : Check for :include: on this address. 804738032Speter | Check for |program on this address. 804838032Speter / Check for /file on this address. 804938032Speter @ Look up sender header addresses in the user 805038032Speter database. Applies to the mailer flags for the 805138032Speter mailer corresponding to the envelope sender 805238032Speter address, rather than to recipient mailer flags. 805338032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 805438032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 805538032Speter mailers, and the ColonOkInAddresses option. 805638032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 805738032Speter John Beck of Hewlett-Packard, who generously contributed 805838032Speter their implementation to me, which I then didn't use (see 805938032Speter mime.c for an explanation of why). This adds the 806038032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 806138032Speter to control handling of 8-bit data. These have to cope with 806238032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 806338032Speter 8-bit data that is entered without declaring it as 8-bit 806438032Speter MIME -- technically this is illegal according to the 806538032Speter specs) and labelled 8-bit data (that is, it was declared 806638032Speter as 8BITMIME in the ESMTP session or by using the 806738032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 806838032Speter set then 8-bit data is sent to non-8BITMIME machines 806938032Speter instead of converting to 7 bit (essentially using 807038032Speter just-send-8 semantics). The values for EightBitMode are: 807138032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 807238032Speter any necessary conversion of 8BITMIME to 7BIT 807338032Speter (essentially, the full MIME option). 807438032Speter p pass unlabelled 8-bit input, but convert labelled 807538032Speter 8BITMIME input to 7BIT as required (default). 807638032Speter s strict adherence: reject unlabelled 8-bit input, 807738032Speter convert 8BITMIME to 7BIT as required. The F=8 807838032Speter flag is ignored. 807938032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 808038032Speter the setting of F=8. 808138032Speter Add new internal class 'n', which is the set of MIME Content-Types 808238032Speter which can not be 8 to 7 bit encoded because of other 808338032Speter considerations. Types "multipart/*" and "message/*" are 808438032Speter never directly encoded (although their components can be). 808538032Speter Add new internal class 's', which is the set of subtypes of the 808638032Speter MIME message/* content type that can be treated as though 808738032Speter they are an RFC822 message. It is predefined to have 808838032Speter "rfc822". Suggested By Kari Hurtta. 808938032Speter Add new internal class 'e'. This is the set of MIME 809038032Speter Content-Transfer-Encodings that can be converted to 809138032Speter a seven bit format (Quoted-Printable or Base64). It is 809238032Speter preinitialized to contain "7bit", "8bit", and "binary". 809338032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 809438032Speter short name) to set the default character set to use in the 809538032Speter Content-Type: header when doing encoding of an 8-bit message 809638032Speter which isn't marked as MIME into MIME format. If the C= 809738032Speter parameter is set on the Envelope From address, use that as 809838032Speter the default encoding; else use the DefaultCharSet option. 809938032Speter If neither is set, it defaults to "unknown-8bit" as 810038032Speter suggested by RFC 1428 section 3. 810138032Speter Allow ``U=user:group'' field in mailer definition to set a default 810238032Speter user and group that a mailer will be executed as. This 810338032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 810438032Speter also set, it is the uid/gid that will always be used (that 810538032Speter is, the controlling address is ignored). The values may be 810638032Speter numeric or symbolic; if only a symbolic user is given (no 810738032Speter group) that user's default group in the passwd file is used 810838032Speter as the group. Based on code donated by Chip Rosenthal of 810938032Speter Unicom. 811038032Speter Allow `u' option to also accept user:group as a value, in the same 811138032Speter fashion as the U= mailer option. 811238032Speter Add the symbolic time zone name in the Arpanet format dates (as 811338032Speter a comment). This adds a new compile-time configuration 811438032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 811538032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 811638032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 811738032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 811838032Speter timezone()), or TZ_NONE (don't include the comment). Code 811938032Speter from Chip Rosenthal. 812038032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 812138032Speter For example, 812238032Speter O Timeout.helo = 2m 812338032Speter There are also two new suboptions "queuereturn" and 812438032Speter "queuewarn"; these subsume the old T option. Thus, to 812538032Speter set them both the preferred new syntax is 812638032Speter O Timeout.queuereturn = 5d 812738032Speter O Timeout.queuewarn = 4h 812838032Speter Sort queue by host name instead of by message priority if the 812938032Speter QueueSortOrder option (no short name) is set is set to 813038032Speter ``host''. This makes better use of the connection cache, 813138032Speter but may delay more ``interactive'' messages behind large 813238032Speter backlogs under some circumstances. This is probably a 813338032Speter good option if you have high speed links or don't do lots 813438032Speter of ``batch'' messages, but less good if you are using 813538032Speter something like PPP on a 14.4 modem. Based on code 813638032Speter contributed by Roy Mongiovi of Georgia Tech (my main 813738032Speter contribution was to make it configurable). 813838032Speter Save i-number of df file in qf file to simplify rebuilding of queue 813938032Speter after disastrous disk crash. Suggested by Kyle Jones of 814038032Speter UUNET; closely based on code from KJS DECWRL code written 814138032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 814238032Speter are NOT back compatible with 8.6 -- that is, you can convert 814338032Speter from 8.6 to 8.7, but not the other direction. 814438032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 814538032Speter route-addrs in envelopes; this is because in some cases 814638032Speter they can be sent to the shell, which interprets them as 814738032Speter I/O redirection. 814838032Speter Don't include error file (option E) with return-receipts; this 814938032Speter can be confusing. 815038032Speter Don't send "Warning: cannot send" messages to owner-* or 815138032Speter *-request addresses. Suggested by Christophe Wolfhugel 815238032Speter of the Institut Pasteur, Paris. 815338032Speter Allow -O command line flag to set long form options. 815438032Speter Add "MinQueueAge" option to set the minimum time between attempts 815538032Speter to run the queue. For example, if the queue interval 815638032Speter (-q value) is five minutes, but the minimum queue age 815738032Speter is fifteen minutes, jobs won't be tried more often than 815838032Speter once every fifteen minutes. This can be used to give 815938032Speter you more responsiveness if your delivery mode is set to 816038032Speter queue-only. 816138032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 816238032Speter :include: and .forward files. 816338032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 816438032Speter key field name, the value field name, and the field 816538032Speter delimiter. The field delimiter can be a single character 816638032Speter or the sequence "\t" or "\n" for tab or newline. 816738032Speter These are for use by NIS+ and similar access methods. 816838032Speter Change maps to always strip quotes before lookups; the -q flag 816943730Speter turns off this behavior. Suggested by Motonori Nakamura. 817038032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 817138032Speter key and value field names respectively. Code donated by 817238032Speter Sun Microsystems. 817338032Speter Add "hesiod" map class. The "file name" is used as the 817438032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 817538032Speter first value found for the match. Code donated by Scott 817638032Speter Hutton of Indiana University. 817738032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 817838032Speter specify the name of the property that is searched as the 817938032Speter key and a -v flag to specify the name of the property that 818038032Speter is returned as the value (defaults to "members"). The 818138032Speter default map is "/aliases". Some code based on code 818238032Speter contributed by Robert La Ferla of Hot Software. 818338032Speter Add "text" map class. This does slow, linear searches through 818438032Speter text files. The -z flag specifies a column delimiter 818538032Speter (defaults to any sequence of white space), the -k flag 818638032Speter sets the key column number, and the -v flag sets the 818738032Speter value column number. Lines beginning with `#' are treated 818838032Speter as comments. 818938032Speter Add "program" map class to execute arbitrary programs. The search 819038032Speter key is presented as the last argument; the output is one 819138032Speter line read from the programs standard output. Exit statuses 819238032Speter are from sysexits.h. 819338032Speter Add "sequence" map class -- searches maps in sequence until it 819438032Speter finds a match. For example, the declarations: 819538032Speter Kmap1 ... 819638032Speter Kmap2 ... 819738032Speter Kmapseq sequence map1 map2 819838032Speter defines a map "mapseq" that first searches map1; if the 819938032Speter value is found it is returned immediately, otherwise 820038032Speter map2 is searched and the value returned. 820138032Speter Add "switch" map class. This is much like "sequence" except that 820238032Speter the ordering is fetched from an external file, usually 820338032Speter the system service switch. The parameter is the name of 820438032Speter the service to switch on, and the maps that it will use 820538032Speter are the name of the switch map followed by ".service_type". 820638032Speter For example, if the declaration of the map is 820738032Speter Ksample switch hosts 820838032Speter and the system service switch specifies that hosts are 820938032Speter looked up using dns and nis in that order, then this is 821038032Speter equivalent to 821138032Speter Ksample sequence sample.dns sample.nis 821238032Speter The subordinate maps (sample.*) must already be defined. 821338032Speter Add "user" map class -- looks up users using getpwnam. Takes a 821438032Speter "-v field" flag on the definition that tells what passwd 821538032Speter entry to return -- legal values are name, passwd, uid, gid, 821638032Speter gecos, dir, and shell. Generally expected to be used with 821738032Speter the -m (matchonly) flag. 821838032Speter Add "bestmx" map class -- returns the best MX value for the host 821938032Speter listed as the value. If there are several "best" MX records 822038032Speter for this host, one will be chosen at random. 822138032Speter Add "userdb" map class -- looks up entries in the user database. 822238032Speter The "file name" is actually the tag that will be used, 822338032Speter typically "mailname". If there are multiple entries 822438032Speter matching the name, the one chosen is undefined. 822538032Speter Add multiple queue timeouts (both return and warning). These are 822638032Speter set by the Precedence: or Priority: header fields to one of 822738032Speter three values. If a Priority: is set and has value "normal", 822864562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 822938032Speter used. If no priority is set, the Precedence: is consulted; 823038032Speter if negative, non-urgent timeouts are used; if greater than 823138032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 823238032Speter are used. The timeouts are set by setting the six timeouts 823338032Speter queue{warn,return}.{urgent,normal,non-urgent}. 823438032Speter Fix problem when a mail address is resolved to a $#error mailer 823538032Speter with a temporary failure indication; it works in SMTP, 823638032Speter but when delivering locally the mail is silently discarded. 823738032Speter This patch, from Kyle Jones of UUNET, bounces it instead 823838032Speter of queueing it (queueing is very hard). 823938032Speter When using /etc/hosts or NIS-style lookups, don't assume that 824038032Speter the first name in the list is the best one -- instead, 824138032Speter search for the first one with a dot. For example, if 824238032Speter an /etc/hosts entry reads 824338032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 824438032Speter this change will use the second name as the canonical 824538032Speter machine name instead of the initial, unqualified name. 824638032Speter Change dequote map to replace spaces in quoted text with a value 824738032Speter indicated by the -s flag on the dequote map definition. 824838032Speter For example, ``Mdequote dequote -s_'' will change 824938032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 825038032Speter quoted (because of the space character). Suggested by Dan 825138032Speter Oscarsson for use in X.400 addresses. 825238032Speter Implement long macro names as ${name}; long class names can 825338032Speter be similarly referenced as $={name} and $~{name}. 825438032Speter Definitions are (e.g.) ``D{name}value''. Names that have 825538032Speter a leading lower case letter or punctuation characters are 825638032Speter reserved for internal use by sendmail; i.e., config files 825738032Speter should use names that begin with a capital letter. Based 825838032Speter on code contributed by Dan Oscarsson. 825938032Speter Fix core dump if getgrgid returns a null group list (as opposed 826038032Speter to an empty group list, that is, a pointer to a list 826138032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 826238032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 826338032Speter failed, it called syserr which called newstr which called 826438032Speter xalloc.... The newstr is now avoided for "panic" messages. 826538032Speter Reported by Stuart Kemp of James Cook University. 826638032Speter Improve connection cache timeouts; previously, they were not even 826738032Speter checked if you were delivering to anything other than an 826838032Speter IPC-connected host, so a series of (say) local mail 826938032Speter deliveries could cause cached connections to be open 827038032Speter much longer than the specified timeout. 827138032Speter If an incoming message exceeds the maximum message size, stop 827238032Speter writing the incoming bytes to the queue data file, since 827338032Speter this can fill your mqueue partition -- this is a possible 827438032Speter denial-of-service attack. 827538032Speter Don't reject all numeric local user names unless HESIOD is 827638032Speter defined. It turns out that Posix allows all-numeric 827738032Speter user names. Fix from Tony Sanders of BSDI. 827838032Speter Add service switch support. If the local OS has a service 827938032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 828038032Speter on DEC systems) that will be used; otherwise, it falls back 828138032Speter to using a local mechanism based on the ServiceSwitchFile 828238032Speter option (default: /etc/service.switch). For example, if the 828338032Speter service switch lists "files" and "nis" for the aliases 828438032Speter service, that will be the default lookup order. the "files" 828538032Speter ("local" on DEC) service type expands to any alias files 828638032Speter you listed in the configuration file, even if they aren't 828738032Speter actually file lookups. 828838032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 828938032Speter variable which tells whether or not DNS should be considered 829038032Speter canonical. This is now determined based on whether or not 829138032Speter "dns" is in the service list for "hosts". 829238032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 829338032Speter Status Notifications). DSN notifications override 829438032Speter Return-Receipt-To: headers, which are bogus anyhow -- 829538032Speter support for them has been removed. 829638032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 829738032Speter definitions to define the types used in DSN returns for 829838032Speter MTA names, addresses, and diagnostics respectively. 829938032Speter Extend heuristic to force running in ESMTP mode to look for the 830038032Speter five-character string "ESMTP" anywhere in the 220 greeting 830138032Speter message (not just the second line). This is to provide 830238032Speter better compatibility with other ESMTP servers. 830338032Speter Print sequence number of job when running the queue so you can 830438032Speter easily see how much progress you have made. Suggested 830538032Speter by Peter Wemm of DIALix. 830638032Speter Map newlines to spaces in logged message-ids; some versions of 830738032Speter syslog truncate the rest of the line after newlines. 830838032Speter Suggested by Fletcher Mattox of U. Texas. 830938032Speter Move up forking for job runs so that if a message is split into 831038032Speter multiple envelopes you don't get "fork storms" -- this 831138032Speter also improves the connection cache utilization. 831238032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 831338032Speter the purposes of refusing to send error returns. Suggested 831438032Speter by Motonori Nakamura of Ritsumeikan University. 831538032Speter Relax rules on when a file can be written when referenced from 831638032Speter the aliases file: use the default uid/gid instead of the 831738032Speter real uid/gid. This allows you to create a file owned by 831838032Speter and writable only by the default uid/gid that will work 831990792Sgshapiro all the time (without having the set-user-ID bit set). Change 832038032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 832138032Speter Microsystems. 832238032Speter Add "DialDelay" option (no short name) to provide an "extra" 832338032Speter delay for dial on demand systems. If this is non-zero 832438032Speter and a connect fails, sendmail will wait this long and 832538032Speter then try again. If it takes longer than the kernel 832638032Speter timeout interval to establish the connection, this 832738032Speter option can give the network software time to establish 832838032Speter the link. The default units are seconds. 832938032Speter Move logging of sender information to be as early as possible; 833038032Speter previously, it could be delayed a while for SMTP mail 833138032Speter sent to aliases. Suggested by Brad Knowles of the 833238032Speter Defense Information Systems Agency. 833338032Speter Call res_init() before setting RES_DEBUG; this is required by 833438032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 833538032Speter the National Computer Security Center. 833638032Speter Add xdelay= field in logs -- this is a transaction delay, telling 833738032Speter you how long it took to deliver to this address on the 833838032Speter last try. It is intended to be used for sorting mailing 833938032Speter lists to favor "quick" addresses. Provided for use by 834038032Speter the mailprio scripts (see below). 834138032Speter If a map cannot be opened, and that map is non-optional, and 834238032Speter an address requires that map for resolution, queue the 834338032Speter map instead of bouncing it. This involves creating a 834438032Speter pseudo-class of maps called "bogus-map" -- if a required 834538032Speter map cannot be opened, the class is changed to bogus-map; 834638032Speter all queries against bogus-map return "tempfail". The 834738032Speter bogus-map class is not directly accessible. A sample 834838032Speter implementation was donated by Jem Taylor of Glasgow 834938032Speter University Computing Service. 835038032Speter Fix a possible core dump when mailing to a program that talks 835138032Speter SMTP on its standard input. Fix from Keith Moore of 835238032Speter the University of Kentucky. 835338032Speter Make it possible to resolve filenames to $#local $: @ /filename; 835438032Speter previously, the "@" would cause it to not be recognized 835538032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 835638032Speter Accept a -1 signal to re-exec the daemon. This only works if 835738032Speter argv[0] is a full path to sendmail. 835838032Speter Fix bug in "addr=..." field in O option on little-endian machines 835938032Speter -- the network number wasn't being converted to network 836038032Speter byte order. Patch from Kurt Lidl of Pix Technologies 836138032Speter Corporation. 836238032Speter Pre-initialize the resolver early on; this is to avoid a bug with 836338032Speter BIND 4.9.3 that can cause the _res.retry field to get 836438032Speter reset to zero, causing all name server lookups to time 836538032Speter out. Fix from Matt Day of Artisoft. 836638032Speter Restore T line (trusted users) in config file -- but instead of 836738032Speter locking out the -f flag, they just tell whether or not 836838032Speter an X-Authentication-Warning: will be added. This really 836938032Speter just creates new entries in class 't', so "Ft/file/name" 837038032Speter can be used to read trusted user names from a file. 837138032Speter Trusted users are also allowed to execute programs even 837238032Speter if they have a shell that isn't in /etc/shells. 837338032Speter Improve NEWDB alias file rebuilding so it will create them 837438032Speter properly if they do not already exist. This had been 837538032Speter a MAYBENEXTRELEASE feature in 8.6.9. 837638032Speter Check for @:@ entry in NIS maps before starting up to avoid 837738032Speter (but not prevent, sigh) race conditions. This ought to 837838032Speter be handled properly in ypserv, but isn't. Suggested by 837938032Speter Michael Beirne of Motorola. 838038032Speter Refuse connections if there isn't enough space on the filesystem 838138032Speter holding the queue. Contributed by Robert Dana of Wolf 838238032Speter Communications. 838338032Speter Skip checking for directory permissions in the path to a file 838438032Speter when checking for file permissions iff setreuid() 838538032Speter succeeded -- it is unnecessary in that case. This avoids 838638032Speter significant performance problems when looking for .forward 838738032Speter files. Based on a suggestion by Win Bent of USC. 838838032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 838938032Speter arbitrary ruleset number assigned or "Sname = integer" 839038032Speter to assign a specific ruleset number. Reference is 839138032Speter $>name_or_number. Names can be composed of alphas, digits, 839238032Speter underscore, or hyphen (first character must be non-numeric). 839338032Speter Allow -o flag on AliasFile lines to make the alias file optional. 839438032Speter From Bryan Costales of ICSI. 839538032Speter Add NoRecipientAction option to handle the case where there is 839638032Speter no legal recipient header in the message. It can take 839738032Speter on values: 839838032Speter None Leave the message as is. The 839938032Speter message will be passed on even 840038032Speter though it is in technically 840138032Speter illegal syntax. 840238032Speter Add-To Add a To: header with any 840338032Speter recipients that it can find from 840438032Speter the envelope. This risks exposing 840538032Speter Bcc: recipients. 840638032Speter Add-Apparently-To Add an Apparently-To: header. This 840738032Speter has almost no redeeming social value, 840838032Speter and is provided only for back 840938032Speter compatibility. 841038032Speter Add-To-Undisclosed Add a header reading 841138032Speter To: undisclosed-recipients:; 841238032Speter which will have the effect of 841338032Speter making the message legal without 841438032Speter exposing Bcc: recipients. 841538032Speter Add-Bcc To add an empty Bcc: header. 841638032Speter There is a chance that mailers down 841738032Speter the line will delete this header, 841838032Speter which could cause exposure of Bcc: 841938032Speter recipients. 842038032Speter The default is NoRecipientAction=None. 842138032Speter Truncate (rather than delete) Bcc: lines in the header. This 842238032Speter should prevent later sendmails (at least, those that don't 842338032Speter themselves delete Bcc:) from considering this message to 842438032Speter be non-conforming -- although it does imply that non-blind 842538032Speter recipients can see that a Bcc: was sent, albeit not to whom. 842638032Speter Add SafeFileEnvironment option. If declared, files named as delivery 842738032Speter targets must be regular files in addition to the regular 842838032Speter checks. Also, if the option is non-null then it is used as 842938032Speter the name of a directory that is used as a chroot(2) 843038032Speter environment for the delivery; the file names listed in an 843138032Speter alias or forward should include the name of this root. 843238032Speter For example, if you run with 843338032Speter O SafeFileEnvironment=/arch 843438032Speter then aliases should reference "/arch/rest/of/path". If a 843538032Speter value is given, sendmail also won't try to save to 843638032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 843738032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 843838032Speter Support -A flag for alias files; this will comma concatenate like 843938032Speter entries. For example, given the aliases: 844038032Speter list: member1 844138032Speter list: member2 844238032Speter and an alias file declared as: 844338032Speter OAhash:-A /etc/aliases 844438032Speter the final alias inserted will be "list: member1,member2"; 844538032Speter without -A you will get an error on the second and subsequent 844638032Speter alias for "list". Contributed by Bryan Costales of ICSI. 844738032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 844838032Speter Fix a problem that could cause very long addresses to core dump in 844938032Speter some special circumstances. Problem pointed out by Allan 845038032Speter Johannesen. 845138032Speter (Internal change.) Change interface to expand() (macro expansion) 845238032Speter to be simpler and more consistent. 845338032Speter Delete check for funny qf file names. This didn't really give 845438032Speter any extra security and caused some people some problems. 845538032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 845638032Speter at compile time.) Suggested by Kyle Jones of UUNET. 845738032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 845838032Speter merge with DSN code; this is simpler and more consistent. 845938032Speter This may affect some people who have written their own 846038032Speter checkcompat() routine. 846138032Speter (Internal change.) Eliminate `D' line in qf file. The df file 846238032Speter is now assumed to be the same name as the qf file (with 846338032Speter the `q' changed to a `d', of course). 846438032Speter Avoid forking for delivery if all recipient mailers are marked as 846538032Speter "expensive" -- this can be a major cost on some systems. 846638032Speter Essentially, this forces sendmail into "queue only" mode 846738032Speter if all it is going to do is queue anyway. 846838032Speter Avoid sending a null message in some rather unusual circumstances 846938032Speter (specifically, the RCPT command returns a temporary 847038032Speter failure but the connection is lost before the DATA 847138032Speter command). Fix from Scott Hammond of Secure Computing 847238032Speter Corporation. 847338032Speter Change makesendmail to use a somewhat more rational naming scheme: 847438032Speter Makefiles and obj directories are named $os.$rel.$arch, 847538032Speter where $os is the operating system (e.g., SunOS), $rel is 847638032Speter the release number (e.g., 5.3), and $arch is the machine 847738032Speter architecture (e.g., sun4). Any of these can be omitted, 847838032Speter and anything after the first dot in a release number can 847938032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 848038032Speter version used $os.$arch.$rel and was rather less general. 848138032Speter Change makesendmail to do a "make depend" in the target directory 848238032Speter when it is being created. This involves adding an empty 848338032Speter "depend:" entry in most Makefiles. 848438032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 848538032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 848638032Speter of the Finnish Meteorological Institute. 848738032Speter Fix problem that could cause multiple responses to DATA command 848838032Speter on header syntax errors (e.g., lines beginning with colons). 848938032Speter Problem noted by Jens Thomassen of the University of Oslo. 849038032Speter Don't let null bytes in headers cause truncation of the rest of 849138032Speter the header. 849238032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 849338032Speter Increase timeouts on message data puts to allow time for receivers 849438032Speter to canonify addresses in headers on the fly. This is still 849538032Speter a rather ugly heuristic. From Motonori Nakamura. 849638032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 849738032Speter records are not used when canonifying names, and when MX 849838032Speter lookups are done for addressing they must be fully 849938032Speter qualified. This is useful if you have a wildcard MX record, 850038032Speter although it may cause other problems. In general, don't use 850138032Speter wildcard MX records. Patch from Motonori Nakamura. 850238032Speter Eliminate default two-line SMTP greeting message. Instead of 850338032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 850438032Speter is added between the first and second word of the first 850538032Speter line of the greeting message (i.e., immediately after the 850638032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 850738032Speter compile flag. Old sendmails won't see the ESMTP, but that's 850838032Speter acceptable because SIZE was the only useful extension that 850938032Speter old sendmails understand. 851038032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 851138032Speter invoked state dumps. From Masaharu Onishi. 851238032Speter Allow on-line comments in .forward and :include: files; they are 851338032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 851438032Speter is a space or a tab. This is intended for native 851538032Speter representation of non-ASCII sets such as Japanese, where 851638032Speter existing encodings would be unreadable or would lose 851738032Speter data -- for example, 851838032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 851938032Speter (romanized/less information) 852038032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 852138032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 852238032Speter (with MIME encoding, not human readable) 852338032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 852438032Speter (native encoding with ISO-2022-JP) 852538032Speter The last form is human readable in the Japanese environment. 852638032Speter Based on a fix from (surprise!) Motonori Nakamura. 852738032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 852838032Speter messages to that host; these are most frequently associated 852938032Speter with addresses rather than the host, with the exception of 853038032Speter 421 (service shutting down). The effect was to cause queues 853138032Speter to sometimes take an excessive time to flush. Reported by 853238032Speter Robert Sargent of Southern Geographics Technologies and 853338032Speter Eric Prestemon of American University. 853438032Speter Add Nice=N mailer option to set the niceness at which a mailer will 853538032Speter run. This is actually a relative niceness (that is, an 853638032Speter increment on the background value). 853738032Speter Log queue runs that are skipped due to high loads. They are logged 853838032Speter at LOG_INFO priority iff the log level is > 8. Contributed 853938032Speter by Bruce Nagel of Data General. 854038032Speter Allow the error mailer to accept a DSN-style error status code 854138032Speter instead of an sysexits status code in the host part. 854238032Speter Anything with a dot will be interpreted as a DSN-style code. 854338032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 854438032Speter to encode characters that might be munged by an EBCDIC system 854538032Speter in addition to the set required by RFC 1521. The additional 854638032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 854738032Speter (Think of "IBM 360" as the mnemonic for this flag.) 854838032Speter Change check for mailing to files to look for a pathname of [FILE] 854938032Speter rather than looking for the mailer named *file*. The mapping 855038032Speter of leading slashes still goes to the *file* mailer. This 855138032Speter allows you to implement the *file* mailer as a separate 855238032Speter program, for example, to insert a Content-Length: header 855338032Speter or do special security policy. However, note that the usual 855438032Speter initial checking for the file permissions is still done, and 855538032Speter the program in question needs to be very careful about how 855638032Speter it does the file write to avoid security problems. 855738032Speter Be able to read ~root/.forward even if the path isn't accessible to 855838032Speter regular users. This is disrecommended because sendmail 855938032Speter sometimes does not run as root (e.g., when an unsafe option 856038032Speter is specified on the command line), but should otherwise be 856138032Speter safe because .forward files must be owned by the user for 856238032Speter whom mail is being forwarded, and cannot be a symbolic link. 856338032Speter Suggested by Forrest Aldrich of Wang Laboratories. 856438032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 856538032Speter file. This is used for canonifying hostnames when the 856638032Speter service type is "files". 856738032Speter Implement programs on F (read class from file) line. The syntax is 856838032Speter Fc|/path/to/program to read the output from the program 856938032Speter into class "c". 857038032Speter Probe the network interfaces to find alternate names for this 857138032Speter host. Requires the SIOCGIFCONF ioctl call. Code 857238032Speter contributed by SunSoft. 857338032Speter Add "E" configuration line to set or propagate environment 857438032Speter variables into children. "E<envar>" will propagate 857538032Speter the named variable from the environment when sendmail 857638032Speter was invoked into any children it calls; "E<envar>=<value>" 857738032Speter sets the named variable to the indicated value. Any 857838032Speter variables not explicitly named will not be in the child 857938032Speter environment. However, sendmail still forces an 858038032Speter "AGENT=sendmail" environment variable, in part to enforce 858138032Speter at least one environment variable, since many programs and 858238032Speter libraries die horribly if this is not guaranteed. 858338032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 858438032Speter alias databases -- new algorithm looks for the substring 858538032Speter "/yp/" in the file name. This is more portable and involves 858638032Speter less overhead. Suggested by Motonori Nakamura. 858738032Speter Dynamically allocate the queue work list so that you don't lose 858838032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 858938032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 859038032Speter should not need to be changed) and the MaxQueueRunSize option, 859138032Speter which is the absolute maximum number of jobs that will ever 859238032Speter be handled in a single queue run. Based on code contributed 859338032Speter by Brian Coan of the Institute for Global Communications. 859438032Speter Log message when a message is dropped because it exceeds the maximum 859538032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 859638032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 859738032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 859838032Speter of Mark G. Thomas Consulting. 859938032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 860038032Speter OS-dependent defines). The old semantic of -d0.1 to not 860138032Speter run the daemon in background has been moved to -d99.100, 860238032Speter and the old 52.5 flag (to avoid disconnect() from closing 860338032Speter all output files) has been moved to 52.100. This makes 860438032Speter things more consistent (flags below .100 don't change 860538032Speter semantics) and separates out the backgrounding so that 860638032Speter it doesn't happen automatically on other unrelated debugging 860738032Speter flags. 860838032Speter If -t is used but no addresses are found in the header, give an 860938032Speter error message rather than just doing nothing. Fix from 861038032Speter Motonori Nakamura. 861138032Speter On systems (like SunOS) where the effective gid is not necessarily 861238032Speter included in the group list returned by getgroups(), the 861338032Speter `restrictmailq' option could sometimes cause an authorized 861438032Speter user to not be able to use `mailq'. Fix from Charles Hannum 861538032Speter of MIT. 861638032Speter Allow symbolic service names for [IPC] mailers. Suggested by 861738032Speter Gerry Magennis of Logica International. 861838032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 861938032Speter when running DNS. For example, if the name FTP.Foo.ORG is 862038032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 862138032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 862238032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 862338032Speter This is technically illegal under RFC 822 and 1123, but the 862438032Speter IETF is moving toward legalizing it. Note that turning on 862538032Speter this option is not sufficient to guarantee that a downstream 862638032Speter neighbor won't rewrite the address for you. 862738032Speter Add "-m" flag to makesendmail script -- this tells you what object 862838032Speter directory and Makefile it will use, but doesn't actually do 862938032Speter the make. 863038032Speter Do some additional checking on the contents of the qf file to try 863138032Speter to detect attacks against the qf file. In particular, 863238032Speter abort on any line beginning "From ", and add an "end of 863338032Speter file" line -- any data after that line is prohibited. 863438032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 863538032Speter choices. This can be overridden in the Makefile by using 863638032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 863738032Speter (to the extent that we know it) or by defining 863838032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 863938032Speter sendmail 8 to have more consistent installation instructions. 864038032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 864138032Speter of Sun Microsystems. 864238032Speter Improved symbol table hash function from Eric Wassenaar. This one 864338032Speter is at least 50% faster. 864438032Speter Fix problem that didn't notice that timeout on file open was a 864538032Speter transient error. Fix from Larry Parmelee of Cornell 864638032Speter University. 864738032Speter Allow comments (lines beginning with a `#') in files read for 864838032Speter classes. Suggested by Motonori Nakamura. 864938032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 865038032Speter of dropping out entirely. This makes testing some of the 865138032Speter name server lookups easier to deal with when there are 865238032Speter hung servers. From Motonori Nakamura. 865338032Speter Add new ${opMode} macro that is set to the current operation mode 865438032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 865538032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 865638032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 865738032Speter Kind of like queue-only mode (Odq) except it tries to avoid 865838032Speter any external service requests; for dial-on-demand hosts that 865938032Speter want to minimize DNS lookups when mail is being queued. For 866038032Speter this to work you will also have to make sure that gethostbyname 866138032Speter of your local host name does not do a DNS lookup. 866238032Speter Improved handling of "out of space" conditions from John Myers of 866338032Speter Carnegie Mellon. 866438032Speter Improved security for mailing to files on systems that have fchmod(2) 866538032Speter support. 866638032Speter Improve "cannot send message for N days" message -- now says "could 866738032Speter not send for past N days". Suggested by Tom Moore of AT&T 866838032Speter Global Information Solutions. 866938032Speter Less misleading Subject: line on messages sent to postmaster only. 867038032Speter From Motonori Nakamura. 867138032Speter Avoid duplicate error messages on bad command line flags. From 867238032Speter Motonori Nakamura. 867338032Speter Better error message for case where ruleset 0 falls off the end 867438032Speter or otherwise does not resolve to a canonical triple. 867538032Speter Fix a problem that could cause multiple bounce messages if a bad 867638032Speter address was sent along with a good address to an SMTP 867738032Speter site where that SMTP site returned a 4yz code in response 867838032Speter to the final dot of the data. Problem reported by David 867938032Speter James of British Telecom. 868038032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 868138032Speter from Alexander Dupuy of System Management ARTS. 868238032Speter Delete duplicates in MX lists -- believe it or not, there are sites 868338032Speter that list the same host twice in an MX list. This deletion 868438032Speter only works on adjacent preferences, so an MX list that 868538032Speter had A=5, B=10, A=15 would leave both As, but one that had 868638032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 868738032Speter just in case there is something weird I haven't thought of. 868838032Speter Suggested by Barry Shein of Software Tool & Die. 868938032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 878438032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 878538032Speter University of Brno (Czech Republic). 878638032Speter KSR OS 1.2.2 support from Todd Miller of the University 878738032Speter of Colorado. 878838032Speter UX4800 support from Kazuhisa Shimizu of NEC. 878938032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 879038032Speter in type ``btree'' maps. The semantics of this are undefined 879138032Speter for regular maps, but it can be useful for the user database. 879238032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 879338032Speter lookups while the rebuild is going on. There is a race 879438032Speter condition between the open(... O_TRUNC ...) and the lock 879538032Speter on the file, but it should be quite small. 879638032Speter SMRSH: sendmail restricted shell added to the release. This can 879738032Speter be used as an alternative to /bin/sh for the "prog" mailer, 879838032Speter giving the local administrator more control over what 879938032Speter programs can be run from sendmail. 880038032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 880138032Speter part of the release proper, and isn't fully supported; in 880238032Speter particular, it does not run on System V based systems and 880338032Speter never will. 880438032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 880538032Speter to allow rmail to compile on systems that don't have 880638032Speter function prototypes and systems that don't have snprintf. 880738032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 880838032Speter lists by transaction delay times so that addresses that 880938032Speter respond quickly get sent first. This is to prevent very 881038032Speter sluggish servers from delaying other peoples' mail. 881138032Speter Contributed by Tony Sanders of BSDI. 881238032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 881338032Speter of BSDI. This has a lot of comments to help people out. 881438032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 881538032Speter put this on the m4 command line. On GNU m4 (which 881638032Speter supports the __file__ primitive) you can run m4 in an 881738032Speter arbitrary directory -- use either: 881838032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 881938032Speter or 882038032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 882138032Speter On other versions of m4 that don't support __file__, you 882238032Speter can use: 882338032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 882438032Speter (Note the trailing slash on the _CF_DIR_ definition.) 882538032Speter Old versions of m4 will default to _CF_DIR_=.. for back 882638032Speter compatibility. 882738032Speter CONFIG: fix mail from <> so it will properly convert to 882838032Speter MAILER-DAEMON on local addresses. 882938032Speter CONFIG: fix code that was supposed to catch colons in host 883038032Speter names. Problem noted by John Gardiner Myers of CMU. 883138032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 883238032Speter From Paul Riddle of the University of Maryland, Baltimore 883338032Speter County. 883438032Speter CONFIG: Catch and reject "." as a host address. 883538032Speter CONFIG: Generalize domaintable to look up all domains, not 883638032Speter just unqualified ones. 883738032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 883838032Speter was never used and didn't work anyway. 883938032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 884038032Speter and d on all mailers in the UUCP class. 884138032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 884238032Speter look for an alias for "user+detail", then for "user+*", and 884338032Speter finally for "user". This is intended for forwarding mail 884438032Speter for system aliases such as root and postmaster to a 884538032Speter centralized hub. 884638032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 884738032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 884838032Speter The F=8 flag is also set on the "relay" mailer, since 884938032Speter this is expected to be another sendmail. 885038032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 885138032Speter the name of the UUCP_RELAY -- in some cases, this is the 885238032Speter wrong value (e.g., when we have local UUCP connections), 885338032Speter and this can create unreplyable addresses. From Chip 885438032Speter Rosenthal of Unicom. 885538032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 885664562Sgshapiro Received: header inserted into all messages. Suggested by 885738032Speter Gary Mills of the University of Manitoba. 885838032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 885943730Speter to get the old behavior. I did this upon observing 886038032Speter that almost everyone needed this feature, and that the 886138032Speter concept I was trying to make happen didn't work with 886238032Speter some user agents anyway. FEATURE(notsticky) still works, 886338032Speter but it is a no-op. 886438032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 886538032Speter names are sent, rather than immediately diagnosing them 886638032Speter as User Unknown. 886738032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 886838032Speter and RELAY_MAILER_ARGS to set the arguments for the 886938032Speter indicated mailers. All default to "IPC $h". Patch from 887038032Speter Larry Parmelee of Cornell University. 887138032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 887238032Speter on the client side" and F=P to get an appropriate 887338032Speter return-path. From Kimmo Suominen. 887438032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 887538032Speter as the local mailer. For addresses of the form "user+detail" 887638032Speter the "detail" part is passed to procmail via the -a flag. 887738032Speter Contributed by Kimmo Suominen. 887838032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 887938032Speter use from mailertables. This lets you execute arbitrary 888038032Speter procmail scripts. Contributed by Kimmo Suominen. 888138032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 888238032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 888338032Speter Paul Southworth of CICNet Systems Support. 888438032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 888538032Speter This causes the null return path to be rewritten as 888638032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 888738032Speter From Michael Hohmuth of Technische Universitat Dresden. 888838032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 888938032Speter list us as the best possible MX record to be treated as 889038032Speter though they were local (essentially, assume that they 889138032Speter are included in $=w). This can cause additional DNS 889238032Speter traffic, but is easier to administer if this fits your 889338032Speter local model. It does not work reliably if there are 889438032Speter multiple hosts that share the best MX preference. 889538032Speter Code contributed by John Oleynick of Rutgers. 889638032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 889738032Speter SHell) instead of /bin/sh as the program used for delivery 889838032Speter to programs. If an argument is included, it is used as 889938032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 890038032Speter assumed. 890138032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 890238032Speter size of messages to the local and procmail mailers 890338032Speter respectively. Contributed by Brad Knowles of the Defense 890438032Speter Information Systems Agency. 890538032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 890638032Speter (just like text outside of angle brackets) in order to 890738032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 890838032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 890938032Speter any real systems any more) and tweak the DOMAIN macro 891038032Speter so that it is less likely that users will accidentally use 891138032Speter the Berkeley defaults. Also, create some generic files 891238032Speter that really can be used in the real world. 891338032Speter CONFIG: Add new configuration macros to set character sets for 891438032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 891538032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 891638032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 891738032Speter The old name will still be accepted for a while at least. 891838032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 891938032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 892038032Speter As with all relays, it can be ``mailer:hostname''. Suggested 892138032Speter by Scott Hutton. 892238032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 892338032Speter by Barb Dijker of Labyrinth Computer Services. 892438032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 892538032Speter performance for large alias files, and this confused many 892638032Speter people. 892738032Speter CONFIG: Add confCF_VERSION to append local information to the 892838032Speter configuration version number displayed during SMTP startup. 892938032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 893038032Speter would only work when locally addressed. Fix from 893138032Speter Edvard Tuinder of Cistron Internet Services. 893238032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 893343730Speter "n" (CheckAliases) is set when rebuilding alias database. 893438032Speter Based on code contributed by Claude Marinier. 893538032Speter CONFIG: Allow mailertable to have values of the form 893638032Speter ``error:code message''. The ``code'' is a status code 893738032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 893838032Speter Contributed by David James <dwj@agw.bt.co.uk>. 893938032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 894038032Speter sender domains that will be replaced with the masquerade name. 894138032Speter These domains will not be treated as local, but if mail passes 894238032Speter through with sender addresses in those domains they will be 894338032Speter replaced by the masquerade name. These can also be specified 894438032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 894538032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 894638032Speter as well as the header. Substantial improvements to this 894738032Speter code were contributed by Per Hedeland. 894838032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 894938032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 895038032Speter by Kimmo Suominen. 895138032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 895238032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 895338032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 895438032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 895538032Speter UUCP addressing.

This caused UnixWare 909838032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 909938032Speter Novell Labs Europe. 910038032Speter Fix problem with static linking of local getopt routine when 910138032Speter using GNU's ld command. Fix from John Kennedy of 910238032Speter Cal State Chico. 910338032Speter It was possible to turn off privacy flags. Problem noted by 910438032Speter *Hobbit*. 910538032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 910638032Speter and Liudvikas Bukys. 910738032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 910838032Speter from Spider Boardman. 910938032Speter CONFIG: No changes (version number only, to keep it in sync 911038032Speter with the binaries). 911138032Speter 911264562Sgshapiro8.6.10/8.6.10 1995/02/10 911338032Speter SECURITY: Diagnose bogus values to some command line flags that 911438032Speter could allow trash to get into headers and qf files. 911538032Speter Validate the name of the user returned by the IDENT protocol. 911638032Speter Some systems that really dislike IDENT send intentionally 911738032Speter bogus information. Problem pointed out by Michael Bushnell 911838032Speter of the Free Software Foundation. Has some security 911938032Speter implications. 912038032Speter Fix a problem causing error messages about DNS problems when 912138032Speter the host name contained a percent sign to act oddly 912238032Speter because it was passed as a printf-style format string. 912338032Speter In some cases this could cause core dumps. 912438032Speter Avoid possible buffer overrun in returntosender() if error 912538032Speter message is quite long. From Fletcher Mattox of the 912638032Speter University of Texas. 912738032Speter Fix a problem that would silently drop "too many hops" error 912838032Speter messages if and only if you were sending to an alias. 912938032Speter From Jon Giltner of the University of Colorado and 913038032Speter Dan Harton of Oak Ridge National Laboratory. 913138032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 913238032Speter set and e->e_message was null. Fix from Bruce Nagel of 913338032Speter Data General. 913438032Speter Fix problem that can still cause df files to be left around 913538032Speter after "hop count exceeded" messages. Fix from Andrew 913638032Speter Chang and Shau-Ping Lo of SunSoft. 913738032Speter Fix a problem that can cause buffer overflows on very long 913838032Speter user names (as might occur if you piped to a program 913938032Speter with a lot of arguments). 914038032Speter Avoid returning an error and re-queueing if the host signature 914138032Speter is null; this can occur on addresses like ``user@.''. 914238032Speter Problem noted by Wesley Craig and the University of 914338032Speter Michigan. 914438032Speter Avoid possible calls to malloc(0) if MCI caching is turned 914538032Speter off. Bug fix from Pierre David of the Laboratoire 914638032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 914738032Speter Universite de Versailles - St Quentin, and Jacky 914838032Speter Thibault. 914938032Speter Make a local copy of the line being sent via senttolist() -- in 915038032Speter some cases, buffers could get trashed by map lookups 915138032Speter causing it to do unexpected things. This also simplifies 915238032Speter some of the map code. 915338032Speter CONFIG: No changes (version number only, to keep it in sync 915438032Speter with the binaries). 915538032Speter 915664562Sgshapiro8.6.9/8.6.9 1994/04/19 915738032Speter Do all mail delivery completely disconnected from any terminal. 915838032Speter This provides consistency with daemon delivery and 915938032Speter may have some security implications. 916038032Speter Make sure that malloc doesn't get called with zero size, 916138032Speter since that fails on some systems. Reported by Ed 916238032Speter Hill of the University of Iowa. 916338032Speter Fix multi-line values for $e (SMTP greeting message). Reported 916438032Speter by Mike O'Connor of Ford Motor Company. 916538032Speter Avoid syserr if no NIS domain name is defined, but the map it 916638032Speter is trying to open is optional. From Win Bent of USC. 916738032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 916838032Speter Hesiod support for UDB from Todd Miller of the University of 916938032Speter Colorado. Use "hesiod" as the service name in the U 917038032Speter option. 917138032Speter Fix a problem that failed to set the "authentic" host name (that 917238032Speter is, the one derived from the socket info) if you called 917338032Speter sendmail -bs from inetd. Based on code contributed by 917438032Speter Todd Miller (this problem was also reported by Guy Helmer 917538032Speter of Dakota State University). This also fixes a related 917638032Speter problem reported by Liudvikas Bukys of the University of 917738032Speter Rochester. 917838032Speter Parameterize "nroff -h" in all the Makefiles so people with 917938032Speter variant versions can use them easily. Suggested by 918038032Speter Peter Collinson of Hillside Systems. 918138032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 918238032Speter spaces between parameters instead of one. Reported by 918338032Speter Valdis Kletnieks of Virginia Tech. 918438032Speter Reduce the number of system calls during message collection by 918538032Speter using global timeouts around the collect() loop. This 918638032Speter code was contributed by Eric Wassenaar. 918738032Speter If the initial hostname name gathering results in a name 918838032Speter without a dot (usually caused by NIS misconfiguration) 918938032Speter and BIND is compiled in, directly access DNS to get 919038032Speter the canonical name. This should make life easier for 919138032Speter Solaris systems. If it still can't be resolved, and 919238032Speter if the name server is listed as "required", try again 919338032Speter in 30 seconds. If that also fails, exit immediately to 919438032Speter avoid bogus "config error: mail loops back to myself" 919538032Speter messages. 919638032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 919738032Speter message to explain how much space was available and 919838032Speter sound a bit less threatening. Suggested by Stan Janet 919938032Speter of the National Institute of Standards and Technology. 920038032Speter If mail is delivered to an alias that has an owner, deliver any 920138032Speter requested return-receipt immediately, and strip the 920238032Speter Return-Receipt-To: header from the subsequent message. 920338032Speter This prevents a certain class of denial of service 920438032Speter attack, arguably gives more reasonable semantics, and 920538032Speter moves things more towards what will probably become a 920638032Speter network standard. Suggested by Christopher Davis of 920738032Speter Kapor Enterprises. 920838032Speter Add a "noreceipts" privacy flag to turn off all return receipts 920938032Speter without recompiling. 921038032Speter Avoid printing ESMTP parameters as part of the error message 921138032Speter if there are errors during parsing. This change is 921238032Speter purely cosmetic. 921338032Speter Avoid sending out error messages during the collect phase of 921438032Speter SMTP; there is an MVS mailer from UCLA that gets 921538032Speter confused by this. Of course, I think it's their bug.... 921638032Speter Check for the $j macro getting undefined, losing a dot, or getting 921738032Speter lost from $=w in the daemon before accepting a connection; 921838032Speter if it is, it dumps state, prints a LOG_ALERT message, 921938032Speter and drops core for debugging. This is an attempt to 922038032Speter track down a bug that I thought was long since gone. 922138032Speter If you see this, please forward the log fragment to 922238032Speter sendmail@sendmail.ORG. 922338032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 922438032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 922538032Speter Wolfhugel. 922638032Speter Instead of trying to truncate the listen queue for the server 922738032Speter SMTP port when the load average is too high, just close 922838032Speter the port completely and reopen it later as needed. 922938032Speter This ensures that the other end gets a quick "connection 923038032Speter refused" response, and that the connection can be 923138032Speter recovered later. In particular, some socket emulations 923238032Speter seem to get confused if you tweak the listen queue 923338032Speter size around and can never start listening to connections 923438032Speter again. The down side is that someone could start up 923538032Speter another daemon process in the interim, so you could 923638032Speter have multiple daemons all not listening to connections; 923738032Speter this could in turn cause the sendmail.pid file to be 923838032Speter incorrect. A better approach might be to accept the 923938032Speter connection and give a 421 code, but that could break 924043730Speter other mailers in mysterious ways and have paging behavior 924138032Speter implications. 924238032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 924338032Speter set debugging on the wrong socket. From Eric Wassenaar. 924438032Speter When creating a df* temporary file, be sure you truncate any 924538032Speter existing data in the file -- otherwise system crashes 924638032Speter and the like could result in extra data being sent. 924738032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 924838032Speter doc directory. This includes some additional 924938032Speter information. 925038032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 925138032Speter of recipient envelope addresses. This should have been 925238032Speter handled by the $&h trick, but broke if people were 925338032Speter mixing domainized and UUCP addresses. They should 925438032Speter probably have converted all the way over to uucp-uudom 925538032Speter instead of uucp-{new,old}, but the failure mode was to 925638032Speter loop the mail, which was bad news. 925738032Speter Portability fixes: 925838032Speter Newer BSDI systems (several people). 925938032Speter Older BSDI systems from Christophe Wolfhugel. 926038032Speter Intergraph CLIX, from Paul Southworth of CICNet. 926138032Speter UnixWare, from Evan Champion. 926238032Speter NetBSD from Adam Glass. 926338032Speter Solaris from Quentin Campbell of the University of 926438032Speter Newcastle upon Tyne. 926538032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 926638032Speter Corporation. 926738032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 926838032Speter SunOS (it has setsid() and setvbuf() calls) from 926938032Speter Jonathan Kamens of OpenVision Technologies. 927038032Speter HP-UX from Tor Lillqvist. 927138032Speter New Files: 927238032Speter src/Makefile.CLIX 927338032Speter src/Makefile.NCR3000 927438032Speter doc/changes/Makefile 927538032Speter doc/changes/changes.me 927638032Speter doc/changes/changes.ps 927738032Speter 927864562Sgshapiro8.6.8/8.6.6 1994/03/21 927938032Speter SECURITY: it was possible to read any file as root using the 928038032Speter E (error message) option. Reported by Richard Jones; 928138032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 928238032Speter 928364562Sgshapiro8.6.7/8.6.6 1994/03/14 928438032Speter SECURITY: it was possible to get root access by using weird 928538032Speter values to the -d flag. Thanks to Alain Durand of 928638032Speter INRIA for forwarding me the notice from the bugtraq 928738032Speter list. 928838032Speter 928964562Sgshapiro8.6.6/8.6.6 1994/03/13 929038032Speter SECURITY: the ability to give files away on System V-based 929138032Speter systems proved dangerous -- don't run as the owner 929238032Speter of a :include: file on a system that allows giveaways. 929338032Speter Unfortunately, this also applies to determining a 929438032Speter valid shell. 929538032Speter IMPORTANT: Previous versions weren't expiring old connections 929638032Speter in the connection cache for a long time under some 929738032Speter circumstances. This could result in resource exhaustion, 929838032Speter both at your end and at the other end. This checks the 929938032Speter connections for timeouts much more frequently. From 930038032Speter Doug Anderson of NCSC. 930138032Speter Fix a glitch that snuck in that caused programs to be run as 930238032Speter the sender instead of the recipient if the mail was 930338032Speter from a local user to another local user. From 930438032Speter Motonori Nakamura of Kyoto University. 930538032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 930638032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 930738032Speter Bryan Costales of ICSI. 930838032Speter Change the method used to declare the "statfs" availability; 930938032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 931038032Speter tweaking in conf.c, there is a single #define called 931138032Speter SFS_TYPE which takes on one of six values (SFS_NONE 931238032Speter for no statfs availability, SFS_USTAT for the ustat(2) 931338032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 931438032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 931538032Speter statfs(2) call with the declarations in <sys/vfs.h>, 931638032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 931738032Speter Fix glitch in NetInfo support that could return garbage if 931838032Speter there was no "/locations/sendmail" property. From 931938032Speter David Meyer of the University of Virginia. 932038032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 932138032Speter to allow Linux to turn it off even though it is a 932238032Speter BSD-like system. 932338032Speter Allow setting of "ident" timeout to zero to turn off the ident 932438032Speter protocol entirely. 932538032Speter Make 7-bit stripping local to a connection (instead of to a 932638032Speter mailer); this allows you to specify that SMTP is a 932738032Speter 7-bit channel, but revert to 8-bit should it advertise 932838032Speter that it supports 8BITMIME. You still have to specify 932938032Speter mailer flag 7 to get this stripping at all. 933038032Speter Improve makesendmail script so it handles more cases automatically. 933138032Speter Tighten up restrictions on taking ownership of :include: files 933238032Speter to avoid problems on systems that allow you to give away 933338032Speter files. 933438032Speter Fix a problem that made it impossible to rebuild the alias 933538032Speter file if it was on a read-only file system. From 933638032Speter Harry Edmon of the University of Washington. 933738032Speter Improve MX randomization function. From John Gardiner Myers 933838032Speter of CMU. 933938032Speter Fix a minor glitch causing a bogus message to be printed (used 934038032Speter %s instead of %d in a printf string for the line number) 934138032Speter when a bad queue file was read. From Harry Edmon. 934238032Speter Allow $s to remain NULL on locally generated mail. I'm not 934338032Speter sure this is necessary, but a lot of people have complained 934438032Speter about it, and there is a legitimate question as to whether 934538032Speter "localhost" is legal as an 822-style domain. 934638032Speter Fix a problem with very short line lengths (mailer L= flag) in 934738032Speter headers. This causes a leading space to be added onto 934838032Speter continuation lines (including in the body!), and also 934938032Speter tries to wrap headers containing addresses (From:, To:, 935038032Speter etc) intelligently at the shorter line lengths. Problem 935138032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 935238032Speter Log the real user name when logging syserrs, since these can have 935338032Speter security implications. Suggested by several people. 935438032Speter Fix address logging of cached connections -- it used to always 935538032Speter log the numeric address as zero. This is a somewhat 935638032Speter bogus implementation in that it does an extra system 935738032Speter call, but it should be an inexpensive one. Fix from 935838032Speter Motonori Nakamura. 935938032Speter Tighten up handling of short syslog buffers even more -- there 936038032Speter were cases where the outgoing relay= name was too long 936138032Speter to share a line with delay= and mailer= logging. 936238032Speter Limit the overhead on split envelopes to one open file descriptor 936338032Speter per envelope -- previously the overhead was three 936438032Speter descriptors. This was in response to a problem reported 936538032Speter by P{r (Pell) Emanuelsson. 936638032Speter Fixes to better handle the case of unexpected connection closes; 936738032Speter this redirects the output to the transcript so the info 936838032Speter is not lost. From Eric Wassenaar. 936938032Speter Fix potential string overrun if you macro evaluate a string that 937038032Speter has a naked $ at the end. Problem noted by James Matheson 937138032Speter <jmrm@eng.cam.ac.uk>. 937238032Speter Make default error number on $#error messages 553 (``Requested 937338032Speter action not taken: mailbox name not allowed'') instead of 937438032Speter 501 (``Syntax error in parameters or arguments'') to 937538032Speter avoid bogus "protocol error" messages. 937638032Speter Strip off any existing trailing dot on names during $[ ... $] 937738032Speter lookup. This prevents it from ending up with two dots 937838032Speter on the end of dot terminated names. From Wesley Craig 937938032Speter of the University of Michigan and Bryan Costales of ICSI. 938038032Speter Clean up file class reading so that the debugging information is 938138032Speter more informative. It hadn't been using setclass, so you 938238032Speter didn't see the class items being added. 938338032Speter Avoid core dump if you are running a version of sendmail where 938438032Speter NIS is compiled in, and you specify an NIS map, but 938538032Speter NIS is not running. Fix from John Oleynick of 938638032Speter Rutgers. 938738032Speter Diagnose bizarre case where res_search returns a failure value, 938838032Speter but sets h_errno to a success value. 938938032Speter Make sure that "too many hops" messages are considered important 939038032Speter enough to send an error to the Postmaster (that is, the 939138032Speter address specified in the P option). This fix should 939238032Speter help problems that cause the df file to be left around 939338032Speter sometimes -- unfortunately, I can't seem to reproduce 939438032Speter the problem myself. 939538032Speter Avoid core dump (null pointer reference) on EXPN command; this 939638032Speter only occurred if your log level was set to 10 or higher 939738032Speter and the target account was an alias or had a .forward file. 939838032Speter Problem noted by Janne Himanka. 939938032Speter Avoid "denial of service" attacks by someone who is flooding your 940038032Speter SMTP port with bad commands by shutting the connection 940138032Speter after 25 bad commands are issued. From Kyle Jones of 940238032Speter UUNET. 940338032Speter Fix core dump on error messages with very long "to" buffers; 940438032Speter fmtmsg overflows the message buffer. Fixed by trimming 940538032Speter the to address to 203 characters. Problem reported by 940638032Speter John Oleynick. 940738032Speter Fix configuration for HASFLOCK -- there were some spots where 940838032Speter a #ifndef was incorrectly #ifdef. Pointed out by 940938032Speter George Baltz of the University of Maryland. 941038032Speter Fix a typo in savemail() that could cause the error message To: 941138032Speter lists to be incorrect in some places. From Motonori 941238032Speter Nakamura. 941338032Speter Fix a glitch that can cause duplicate error messages on split 941438032Speter envelopes where an address on one of the lists has a 941538032Speter name server failure. Fix from Voradesh Yenbut of the 941638032Speter University of Washington. 941738032Speter Fix possible bogus pointer reference on ESMTP parameters that 941838032Speter don't have an ``=value'' part. 941938032Speter CNAME loops caused an error message to be generated, but also 942038032Speter re-queued the message. Changed to just re-queue the 942138032Speter message (it's really hard to just bounce it because 942238032Speter of the weird way the name server works in the presence 942338032Speter of CNAME loops). Problem noted by James M.R.Matheson 942438032Speter of Cambridge University. 942538032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 942638032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 942738032Speter user name. Suggested by Andreas Stolcke of ICSI. 942838032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 942938032Speter override it easily in the Makefile -- that is, you can 943038032Speter turn it off using -DNAMED_BIND=0. 943138032Speter If a gethostbyname(...) of an address with a trailing dot fails, 943238032Speter try it without the trailing dot. This is because if 943338032Speter you have a version of gethostbyname() that falls back 943438032Speter to NIS or the /etc/hosts file it will fail to find 943538032Speter perfectly reasonable names that just don't happen to 943638032Speter be dot terminated in the hosts file. You don't want to 943738032Speter strip the dot first though because we're trying to ensure 943838032Speter that country names that match one of your subdomains get 943938032Speter a chance. 944038032Speter PRALIASES: fix bogus output on non-null-terminated strings. 944138032Speter From Bill Gianopoulos of Raytheon. 944238032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 944338032Speter This was in code intended to only catch the self-literal 944438032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 944538032Speter IP address), but the code was broken. However, it will 944638032Speter still do this if $M is defined; this is necessary to 944738032Speter get client configurations to work (sigh). Note that this 944838032Speter means that $M overrides :mailname entries in the user 944938032Speter database! Problem noted by Paul Southworth. 945038032Speter CONFIG: Fix definition of Solaris help file location. From 945138032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 945238032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 945338032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 945438032Speter and USENET_MAILER_MAX to tweak the maximum message 945538032Speter size for various mailers. 945638032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 945738032Speter instead of assuming that it is "inews" for consistency 945838032Speter with other mailers. From Michael Corrigan of UC San Diego. 945938032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 946038032Speter qualify the address in the SMTP envelope as user@{relay|hub} 946138032Speter instead of user@$j. From Bill Wisner of The Well. 946238032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 946338032Speter CONFIG: Don't turn off case mapping of user names in the local 946438032Speter mailer for IRIX. This was different than most every other 946538032Speter system. 946638032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 946738032Speter envelope. Noted by Thierry Besancon 946838032Speter <besancon@excalibur.ens.fr>. 946938032Speter CONFIG: Don't include -z by default on uux line -- most systems 947038032Speter don't want it set by default. Pointed out by Philippe 947138032Speter Michel of Thomson CSF. 947238032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 947338032Speter host name was foo.bar.ray.com and you matched against 947438032Speter ".ray.com", the old implementation bound %1 to "bar" 947538032Speter instead of "foo.bar". Also, allow "." in the mailertable 947638032Speter to match anything -- essentially, take over SMART_HOST. 947738032Speter This also moves matching of explicit local host names 947838032Speter before the mailertable so they don't have to be special 947938032Speter cased in the mailertable data. Reported by Bill 948038032Speter Gianopoulos of Raytheon; the fix for the %1 binding 948138032Speter problem was contributed by Nicholas Comanos of the 948238032Speter University of Sydney. 948338032Speter CONFIG: Don't include "root" in class $=L (users to deliver 948438032Speter locally, even if a hub or relay exists) by default. 948538032Speter This is because of the known bug where definition of 948638032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 948738032Speter both and deliver into the local mailbox. 948838032Speter CONFIG: Move up bitdomain and uudomain handling so that they 948938032Speter are done before .UUCP class matching; uudomain was 949038032Speter reported as ineffective before. This also frees up 949138032Speter diversion 8 for future use. Problem reported by Kimmo 949238032Speter Suominen. 949338032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 949438032Speter into host names. As pointed out by Jonathan Kamens, 949538032Speter these are often used because either the forward or reverse 949638032Speter mapping is broken; this translation makes it broken again. 949738032Speter DOC: Clarify $@ and $: in the Install & Op Guide.

From 952438032Speter Bob Campbell at U.C. Berkeley. 952538032Speter Security fix: group ids were not completely set when programs 952638032Speter were invoked. This caused programs to have group 952738032Speter permissions they should not have had (usually group 952838032Speter daemon instead of their own group). In particular, 952938032Speter Perl scripts would refuse to run. 953038032Speter Security: check to make sure files that are written are not 953138032Speter symbolic links (at least under some circumstances). 953238032Speter Although this does not respond to a specific known 953338032Speter attack, it's just a good idea. Suggested by 953438032Speter Christian Wettergren. 953538032Speter Security fix: if a user had an NFS mounted home directory on 953638032Speter a system with a restricted shell listed in their 953738032Speter /etc/passwd entry, they could still execute any 953838032Speter program by putting that in their .forward file. 953938032Speter This fix prevents that by insisting that their shell 954038032Speter appear in /etc/shells before allowing a .forward to 954138032Speter execute a program or write a file. You can disable 954238032Speter this by putting "*" in /etc/shells. It also won't 954338032Speter permit world-writable :include: files to reference 954438032Speter programs or files (there's no way to disable this). 954543730Speter These behaviors are only one level deep -- for 954638032Speter example, it is legal for a world-writable :include: 954738032Speter file to reference an alias that writes a file, on 954838032Speter the assumption that the alias file is well controlled. 954938032Speter Security fix: root was not treated suspiciously enough when 955038032Speter looking into subdirectories. This would potentially 955138032Speter allow a cracker to examine files that were publicly 955238032Speter readable but in a non-publicly searchable directory. 955338032Speter Fix a problem that causes an error on QUIT on a cached 955438032Speter connection to create problems on the current job. 955538032Speter These are typically unrelated, so errors occur in 955638032Speter the wrong place. 955738032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 955838032Speter runs more responsive to load average, and fixes a 955938032Speter problem that ignored the load average in locally 956038032Speter generated mail. From Eric Wassenaar. 956138032Speter Fix possible core dump on aliases with null LHS. From 956238032Speter John Orthoefer of BB&N. 956338032Speter Revert to using flock() whenever possible -- there are just 956438032Speter too many bugs in fcntl() locking, particularly over 956538032Speter NFS, that cause sendmail to fail in perverse ways. 956638032Speter Fix a bug that causes the connection cache to get confused 956738032Speter when sending error messages. This resulted in 956838032Speter "unexpected close" messages. It should fix itself 956938032Speter on the following queue run. Problem noted by 957038032Speter Liudvikas Bukys of the University of Rochester. 957138032Speter Include $k in $=k as documented in the Install & Op Guide. 957238032Speter This seems odd, but it was documented.... From 957338032Speter Michael Corrigan of UCSD. 957438032Speter Fix problem that caused :include:s from alias files to be 957538032Speter forced to be owned by root instead of daemon 957638032Speter (actually DefUid). From Tim Irvin. 957738032Speter Diagnose unrecognized I option values -- from Mortin Forssen 957838032Speter of the Chalmers University of Technology. 957938032Speter Make "error" mailer work consistently when there is no error 958038032Speter code associated with it -- previously it returned OK 958138032Speter even though there was a real problem. Now it assumes 958238032Speter EX_UNAVAILABLE. 958338032Speter Fix bug that caused the last header line of messages that had 958438032Speter no body and which were terminated with EOF instead of 958538032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 958638032Speter Fix core dump on SMTP mail to programs that failed -- it tried 958738032Speter to go to a "next MX host" when none existed, causing 958838032Speter a core dump. From der Mouse at McGill University. 958938032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 959038032Speter this makes it easier to turn it off (using 959138032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 959238032Speter Fix YP_MASTER_NAME store to use the unupdated result of 959338032Speter gethostname() (instead of myhostname(), which tries 959438032Speter to fully qualify the name) to be consistent with 959538032Speter SunOS. If your hostname is unqualified, this fixes 959638032Speter transfers to slave servers. Bug noted by Keith 959738032Speter McMillan of Ameritech Services, Inc. 959838032Speter Fix Ultrix problem: gethostbyname() can return a very large 959938032Speter (> 500) h_length field, which causes the sockaddr 960038032Speter to be trashed. Use the size of the sockaddr instead. 960138032Speter Fix from Bob Manson of Ohio State. 960238032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 960338032Speter defined -- this confuses gethostbyname on hosts 960438032Speter file lookups, which doesn't understand the trailing 960538032Speter dot convention. 960638032Speter Log SMTP server subprocesses that die with a signal instead 960738032Speter of from a clean exit. 960838032Speter If you don't have option "I" set, don't assume that a DNS 960938032Speter "host unknown" message is authoritative -- it 961038032Speter might still be found in /etc/hosts. 961138032Speter Fix a problem that would cause Deferred: messages to be sent 961238032Speter as the subject of an error message, even though the 961338032Speter actual cause of a message was more severe than that. 961438032Speter Problem noted by Chris Seabrook of OSSI. 961538032Speter Fix race condition in DBM alias file locking. From Kyle 961638032Speter Jones of UUNET. 961738032Speter Limit delivery syslog line length to avoid bugs in some 961838032Speter versions of syslog(3). This adds a new compile time 961938032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 962038032Speter University, which is in turn derived from IDA. 962138032Speter Fix quotes inside of comments in addresses -- previously 962238032Speter it insisted that they be balanced, but the 822 spec 962338032Speter says that they should be ignored. 962438032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 962538032Speter debugging). This also evaluates ruleset 89, if set 962638032Speter (with the null input), and logs the result. This 962738032Speter should be used sparingly, since the rewrite process 962838032Speter is not reentrant. 962938032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 963038032Speter documented in the Bat Book. 963138032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 963238032Speter return an error message and did not requeue the message. 963338032Speter Fix based on code from Roland Dirlewanger of 963438032Speter Reseau Regional Aquarel, Bordeaux, France. 963538032Speter Fix a problem that caused a seg fault if you got a 421 error 963638032Speter code during some parts of connection initialization. 963738032Speter I've only seen this when talking to buggy mailers on 963838032Speter the other end, but it shouldn't give a seg fault in 963938032Speter any case.

Noted by William C Fenner of 968138032Speter the NRL Connection Machine Facility. 968238032Speter Fix a problem that could cause a core dump if the input sequence 968338032Speter had (or somehow acquired) a \231 character. 968438032Speter Make sure that route-addrs always have <angle brackets> around 968538032Speter them in non-SMTP envelopes (SMTP envelopes already do 968638032Speter this properly). 968738032Speter Avoid weird headers on unbalanced punctuation of the form: 968838032Speter ``Joe User <user)'' -- this caused reference to the 968938032Speter null macro. Fix from Rick McCarty of IO.COM. 969038032Speter Fix a problem that caused an alias "user: user@local.host" to 969138032Speter not have the QNOTREMOTE bit set; this caused configs 969238032Speter to act as if FEATURE(notsticky) was defined even when 969338032Speter it was not. The effect of the problem was to make it 969438032Speter very hard to to set up satellite sites that had a few 969538032Speter local accounts, with everything else forwarded to a 969638032Speter corporate hub. Reported by Detlef Drewanz of the 969738032Speter University of Rostock and Mark Frost of NCD. 969838032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 969938032Speter addresses. This is more efficient (fewer name server 970038032Speter calls) and fixes certain unusual configurations, such 970138032Speter as those that have ruleset 4 do something that is 970238032Speter non-idempotent unless a mailer-specific ruleset did 970338032Speter something else.

Briefly, if you are sending to host 977238032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 977338032Speter "foo!baz" remains "foo!baz", and anything else has 977438032Speter the local name prepended. 977538032Speter CONFIG: portability fixes for HP-UX. 977638032Speter DOC: several minor problems fixed in the Install & Op Guide. 977738032Speter MAKEMAP: fix core dump problem on lines that are too long or 977838032Speter which lack newline. From Mark Delany. 977938032Speter MAILSTATS: print sums of columns (total messages & kbytes 978038032Speter in and out of the system). From Tom Ferrin of UC 978138032Speter San Francisco Computer Graphics Lab. 978238032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 978338032Speter On HP-UX, /etc/sendmail.cf has been moved to 978438032Speter /usr/lib/sendmail.cf to match HP sendmail. 978538032Speter Permissions have been tightened up on world-writable 978638032Speter :include: files and accounts that have shells 978738032Speter that are not listed in /etc/shells. This may 978838032Speter cause some .forward files that have worked 978938032Speter before to start failing. 979038032Speter SIGUSR1 dumps some state to the log. 979138032Speter NEW FILES: 979238032Speter src/Makefile.DGUX 979338032Speter src/Makefile.Dynix 979438032Speter src/Makefile.FreeBSD 979538032Speter src/Makefile.Mach386 979638032Speter src/Makefile.NetBSD 979738032Speter src/Makefile.RISCos 979838032Speter src/Makefile.SCO 979938032Speter src/Makefile.SVR4 980038032Speter src/Makefile.Titan 980138032Speter cf/mailer/pop.m4 980238032Speter cf/ostype/bsdi1.0.m4 980338032Speter cf/ostype/dgux.m4 980438032Speter cf/ostype/dynix3.2.m4 980538032Speter cf/ostype/sco3.2.m4 980638032Speter makemap/Makefile.dist 980738032Speter praliases/Makefile.dist 980838032Speter 980964562Sgshapiro8.6.4/8.6.4 1993/10/31 981038032Speter Repair core-dump problem (write to read-only memory segment) 981138032Speter if you fall back to the return-to-Postmaster case in 981238032Speter savemail. Problem reported by Richard Liu. 981338032Speter Immediately diagnose bogus sender addresses in SMTP. This 981438032Speter makes quite certain that crackers can't use this 981538032Speter class of attack. 981638032Speter Reliability Fix: check return value from fclose() and fsync() 981738032Speter in a few critical places. 981838032Speter Minor problem in initsys() that reversed a condition for 981938032Speter redirecting the output channel on queue runs. It's 982038032Speter not clear this code even does anything. From Eric 982138032Speter Wassenaar of the Dutch National Institute for Nuclear 982238032Speter and High-Energy Physics. 982338032Speter Fix some problems that caused queue runs to do "too much work", 982438032Speter such as double-reading the Errors-To: header. From 982538032Speter Eric Wassenaar. 982638032Speter Error messages on writing the temporary file (including the 982738032Speter data file) were getting suppressed in SMTP -- this 982838032Speter fix causes them to be properly reported. From Eric 982938032Speter Wassenaar. 983038032Speter Some changes to support AF_UNIX sockets -- this will only 983138032Speter really become relevant in the next release, but some 983238032Speter people need it for local patches. From Michael 983338032Speter Corrigan of UC San Diego. 983438032Speter Use dynamically allocated memory (instead of static buffers) 983538032Speter for macros defined in initsys() and settime(); since 983638032Speter these can have different values depending on which 983738032Speter envelope they are in. From Eric Wassenaar. 983838032Speter Improve logging to show ctladdr on to= logging; this tells you 983938032Speter what uid/gid processes ran as. 984038032Speter Fix a problem that caused error messages to be discarded if 984138032Speter the sender address was unparseable for some reason; 984238032Speter this was supposed to fall back to the "return to 984338032Speter postmaster" case. 984438032Speter Improve aliaswait backoff algorithm. 984538032Speter Portability patches for Linux (8.6.3 required another header 984638032Speter file) (from Karl London) and SCO UNIX. 984738032Speter CONFIG: patch prog mailer to not strip host name off of envelope 984838032Speter addresses (so that it matches local again). From 984938032Speter Christopher Davis. 985038032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 985138032Speter this prevents uux from seeing lines with null names like 985238032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 985338032Speter Nakamura of Kyoto University. 985438032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 985538032Speter it shouldn't fail miserably. From Motonori Nakamura. 985638032Speter 985764562Sgshapiro8.6.2/8.6.2 1993/10/15 985838032Speter Put a "successful delivery" message in the transcript for 985938032Speter addresses that get return-receipts. 986038032Speter Put a prominent "this is only a warning" message in warning 986138032Speter messages -- some people don't read carefully enough 986238032Speter and end up sending the message several times. 986338032Speter Include reason for temporary failure in the "warning" return 986438032Speter message. Currently, it just says "cannot send for 986538032Speter four hours". 986638032Speter Fix the "Original message received" time generated for 986738032Speter returntosender messages. It was previously listed as 986838032Speter the current time. Bug reported by Eric Hagberg of 986938032Speter Cornell University Medical College. 987038032Speter If there is an error when writing the body of a message, 987138032Speter don't send the trailing dot and wait for a response 987238032Speter in sender SMTP, as this could cause the connection to 987338032Speter hang up under some bizarre circumstances. From Eric 987438032Speter Wassenaar. 987538032Speter Fix some server SMTP synchronization problems caused when 987638032Speter connections fail during message collection. From 987738032Speter Eric Wassenaar. 987838032Speter Fix a problem that can cause srvrsmtp to reject mail if the 987938032Speter name server is down -- it accepts the RCPT but rejects 988038032Speter the DATA command. Problem reported by Jim Murray of 988138032Speter Stratus. 988238032Speter Fix a problem that can cause core dumps if the config file 988338032Speter incorrectly resolves to a null hostname. Reported by 988438032Speter Allan Johannesen of WPI. 988538032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 988638032Speter by non-root users were not put into 988738032Speter X-Authentication-Warning:s as intended because the 988843730Speter config file hadn't set the PrivacyOptions yet. Fix 988938032Speter from Sven-Ove Westberg of the University of Lulea. 989038032Speter Under very odd circumstances, the alias file rebuild code 989138032Speter could get confused as to whether a database was 989238032Speter open or not. 989338032Speter Check "vendor code" on the end of V lines -- this is 989438032Speter intended to provide a hook for vendor-specific 989538032Speter configuration syntax. (This is a "new feature", 989638032Speter but I've made an exception to my rule in a belief 989738032Speter that this is a highly exceptional case.) 989838032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 989938032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 990038032Speter (from Jon Forrest of UC Berkeley) 990138032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 990238032Speter 990364562Sgshapiro8.6.1/8.6 1993/10/08 990438032Speter Portability fixes for A/UX and Encore UMAX V. 990538032Speter Fix error message handling -- if you had a name server down 990638032Speter causing an error during parsing, that message was never 990738032Speter propagated to the queue file. 990838032Speter 990964562Sgshapiro8.6/8.6 1993/10/05 991038032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 991138032Speter conf.h (other systems have the same bug). 991238032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 991338032Speter getdtablesize() instead of sysconf(); a disturbingly 991438032Speter large number of systems defined _SC_OPEN_MAX in the 991538032Speter header files but don't have the syscall. 991638032Speter Another patch to really truly ignore MX records in getcanonname 991738032Speter if trymx == FALSE. 991838032Speter Fix problem that caused the "250 IAA25499 Message accepted for 991938032Speter delivery" message to be omitted if there was an error 992038032Speter in the header of the message (e.g., a bad Errors-To: 992138032Speter line). Pointed out by Michael Corrigan of UCSD. 992238032Speter Announce name of host we are chatting when we get errors; this 992338032Speter is an IDA-ism suggested by Christophe Wolfhugel. 992438032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 992538032Speter Australian Artificial Intelligence Institute), SCO Unix 992638032Speter (from Murray Kucherawy of Hookup Communication Corp.), 992738032Speter NeXT (from Vince DeMarco and myself), Linux (from 992838032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 992938032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 993038032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 993138032Speter Some changes to get around gcc optimizer bugs. From Takahiro 993238032Speter Kanbe. 993338032Speter Fix error recovery in queueup if another tf file of the same 993438032Speter name already exists. Problem stumbled over by Bill 993538032Speter Wisner of The Well. 993638032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 993738032Speter Problem noted by Keith McMillan of Ameritech Services. 993838032Speter Deal with group permissions properly when opening .forward and 993938032Speter :include: files. This relaxes the 8.1C restrictions 994038032Speter slightly more. This includes proper setting of groups 994138032Speter when reading :include: files, allowing you to read some 994238032Speter files that you should be able to read but have previously 994338032Speter been denied unless you owned them or they had "other" 994438032Speter read permission. 994538032Speter Make certain that $j is in $=w (after the .cf is read) so that 994638032Speter if the user is forced to override some silly system, 994738032Speter MX suppression will still work. 994838032Speter Fix a couple of efficiency problems where newstr was double- 994938032Speter calling expensive routines. In at least one case, it 995038032Speter wasn't guaranteed that they would always return the 995138032Speter same result. Problem noted by Christophe Wolfhugel. 995238032Speter Fix null pointer dereference in putoutmsg -- only on an error 995338032Speter condition from a non-SMTP mailer. From Motonori 995438032Speter Nakamura. 995538032Speter Macro expand "C" line class definitions before scanning so that 995638032Speter "CX $Z" works. 995738032Speter Fix problem that caused error message to be sent while still 995838032Speter trying to send the original message if the connection 995938032Speter is closed during a DATA command after getting an error 996038032Speter on an RCPT command (pretty obscure). Problem reported 996138032Speter by John Myers of CMU. 996238032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 996338032Speter term bug. 996438032Speter Fix a nasty bug causing core dumps when returning the "warning: 996538032Speter cannot deliver for N hours -- will keep trying" message; 996643730Speter it only occurred if you had PostmasterCopy set and 996738032Speter only on some architectures. Although sendmail would 996838032Speter keep trying, it would send error messages on each 996938032Speter queue interval. This is an important fix. 997038032Speter Allow u and g options to take user and group names respectively. 997138032Speter Don't do a chdir into the queue directory in -bt mode to make 997238032Speter ruleset testing a bit easier. 997338032Speter Don't allow users to turn off logging (using -oL) on the command 997438032Speter line -- command line can only raise, not lower, logging 997538032Speter level. 997638032Speter Set $u to the original recipient on the SMTP transaction or on 997738032Speter the command line. This is only done if there is exactly 997838032Speter one recipient. Technically, this does not meet the 997938032Speter specs, because it does not guarantee a domain on the 998038032Speter address. 998138032Speter Fix a problem that dumped error messages on bad addresses if 998238032Speter you used the -t flag. Problem noted by Josh Smith of 998338032Speter Harvey Mudd College. 998438032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 998538032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 998638032Speter avoid the problem of people who use angle brackets in 998738032Speter their full name information. 998838032Speter Fix a null pointer dereference if you set option "l", have 998938032Speter an Errors-To: header in the message, and have Errors-To: 999038032Speter defined in the config file H lines. From J.R. Oldroyd. 999138032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 999238032Speter wrong when compiling. Suggested by Rick McCarty of TI. 999338032Speter Fix a problem that could pass negative SIZE parameter if the 999438032Speter df file got lost; this would cause servers to always 999538032Speter give a temporary failure, making the problem even worse. 999638032Speter Problem noted by Allan Johannesen of WPI. 999738032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 999838032Speter protocol timeouts (30s default). Requested by Murray 999938032Speter Kucherawy of HookUp Communication Corp. to handle bogus 1000038032Speter PC TCP/IP implementations. 1000138032Speter Change $w default definition to be just the first component of 1000238032Speter the domain name on config level 5. The $j macro defaults 1000338032Speter to the FQDN; $m remains as before. This lets well-behaved 1000438032Speter config files use any of the short, long, or subdomain 1000538032Speter names. 1000638032Speter Add makesendmail script in src to try to automate multi-architecture 1000738032Speter builds. I know, this is sub-optimal, but it is still 1000838032Speter helpful. 1000938032Speter Fix very obscure race condition that can cause a queue run to 1001038032Speter get a queue file for an already completed job. This 1001138032Speter problem has existed for years. Problem noted by the 1001238032Speter long suffering Allan Johannesen of WPI. 1001338032Speter Fix a problem that caused the raw sender name to be passed to 1001438032Speter udbsender instead of the canonified name -- this caused 1001538032Speter it to sometimes miss records that it should have found. 1001638032Speter Relax check of name on HELO packet so that a program using -bs 1001738032Speter that claims to be itself works properly. 1001838032Speter Restore rewriting of $: part of address through 2, R, 4 in 1001938032Speter buildaddr -- this requires passing a lot of flags to get 1002038032Speter it right. Unlike old versions, this ONLY rewrites 1002138032Speter recipient addresses, not sender addresses. 1002238032Speter Fix a bug that caused core dumps in config files that cannot 1002338032Speter resolve /file/name style addresses. Fix from Jonathan 1002438032Speter Kamens of OpenVision Technologies. 1002538032Speter Fix problem with fcntl locking that can cause error returns to 1002638032Speter be lost if the lock is lost; this required fully 1002738032Speter queueing everything, dropping the envelope (so errors 1002838032Speter would get returned), and then re-reading the queue from 1002938032Speter scratch. 1003038032Speter Fix a problem that caused aliases that redefine an otherwise 1003138032Speter true address to still send to the original address 1003238032Speter if and only if the alias failed in certain bizarre 1003338032Speter ways (e.g, if they pointed at a list:; syntax address). 1003438032Speter Problem pointed out by Jonathan Kamens. 1003538032Speter Remove support for frozen configuration files. They caused 1003638032Speter more trouble than it was worth. 1003738032Speter Fix problem that can cause error messages to get ignored when 1003838032Speter using both -odb and -t flags. Problem noted by Rob 1003938032Speter McNicholas at U.C. Berkeley. 1004038032Speter Include all "normal" variations on hostname in $=w. For example, 1004138032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 1004238032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 1004338032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 1004438032Speter the queue. 1004538032Speter Reset SmtpPhase global on initial connection creation so that 1004638032Speter messages don't come out with stale information. 1004738032Speter Pass an "ext" argument to lockfile so that error/log messages 1004838032Speter will properly reflect the true filename being locked. 1004938032Speter Put all [...] address forms into $=w -- this eliminates the need 1005038032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 1005138032Speter Myers of CMU. 1005238032Speter Fix a bug that can cause qf files to be left around even after 1005338032Speter an SMTP RSET command. Problem and fix from Michael 1005438032Speter Corrigan. 1005543730Speter Don't send a PostmasterCopy to errors when the Precedence: is 1005638032Speter negative. Error reports still go to the envelope 1005738032Speter sender address. 1005838032Speter Add LA_SHORT for load averages. 1005938032Speter Lock sendmail.st file when posting statistics. 1006038032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 1006138032Speter set the size of the TCP send and receive buffers; if you 1006238032Speter run over a slow slip line you may need to set these down 1006338032Speter (although it would be better to fix the SLIP implementation 1006438032Speter so that it's not necessary to recompile every program 1006538032Speter that does bulk data transfer). 1006638032Speter Allow null defaults on $( ... $) lookups. Problem reported by 1006738032Speter Amir Plivatsky. 1006838032Speter Diagnose crufty S and V config lines. This resulted from an 1006938032Speter observation that some people were using the SITE macro 1007038032Speter without the SITECONFIG macro first, which was causing 1007138032Speter bogus config files that were not caught. 1007238032Speter Fix makemap -f flag to turn off case folding (it was turning it 1007338032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 1007438032Speter Fix a problem that caused multiple error messages to be sent if 1007538032Speter you used "sendmail -t -oem -odb", your system uses fcntl 1007638032Speter locking, and one of the recipient addresses is unknown. 1007738032Speter Reset uid earlier in include() so that recursive .forwards or 1007838032Speter :include:s don't use the wrong uid. 1007938032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 1008038032Speter called, the code to recover the descriptor was broken. 1008138032Speter This sometimes (only sometimes) caused problems with the 1008238032Speter alias file. Fix from Motonori Nakamura. 1008338032Speter Fix a problem that caused aliaswait to go into infinite recursion 1008438032Speter if the @:@ metasymbol wasn't found in the alias file. 1008538032Speter Improve error message on newaliases if database files cannot be 1008638032Speter opened or if running with no database format defined. 1008738032Speter Do a better estimation of the size of error messages when NoReturn 1008838032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 1008938032Speter Fix a problem causing the "c" option (don't connect to expensive 1009038032Speter mailers) to be ignored in SMTP. Problem noted and the 1009138032Speter solution suggested by Robert Elz of The University of 1009238032Speter Melbourne. 1009338032Speter Improve connection caching algorithm by passing "[host]" to 1009438032Speter hostsignature, which strips the square brackets and 1009538032Speter returns the real name. This allows mailertable entries 1009638032Speter to match regular entries. 1009738032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 1009838032Speter feature, even if it doesn't work right. 1009938032Speter Catch and log attempts to try the "wiz" command in server SMTP. 1010038032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 1010138032Speter Be more generous at assigning $z to the home directory -- do this 1010238032Speter for programs that are specified through a .forward file. 1010338032Speter Fix from Andrew Chang of Sun Microsystems. 1010438032Speter Always save a fatal error message in preference to a non-fatal 1010538032Speter error message so that the "subject" line of return 1010638032Speter messages is the best possible. 1010738032Speter CONFIG: reduce the number of quotes needed to quote configuration 1010838032Speter parameters with commas: two quotes should work now, e.g., 1010938032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 1011038032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 1011138032Speter connections (domain-ized UUCP). 1011238032Speter CONFIG: fix bug in default maps (-o must be before database file 1011364562Sgshapiro name). Pointed out by Christophe Wolfhugel. 1011438032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 1011538032Speter DNS. This would presumably be used in UUCP islands. 1011638032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 1011738032Speter CONFIG: log $u in Received: line. This is in technical violation 1011838032Speter of the standards, since it doesn't guarantee a domain 1011938032Speter on the address. 1012038032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 1012138032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 1012238032Speter the "m" flag should you want it. Apparently some Solaris 2.2 1012338032Speter installations can't handle multiple local recipients. 1012438032Speter Problem noted by Josh Smith. 1012538032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 1012638032Speter CONFIG: change default version level from 4 to 5. 1012738032Speter CONFIG: add FEATURE(nullclient) to create a config file that 1012838032Speter forwards all mail to a hub without ever looking at the 1012938032Speter addresses in any detail. 1013038032Speter CONFIG: properly strip mailer: information off of relays when 1013138032Speter used to change .BITNET form into %-hack form. 1013238032Speter CONFIG: fix a problem that caused infinite loops if presented 1013338032Speter with an address such as "!foo". 1013438032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 1013538032Speter the reverse "PTR" mapping is broken. There's a better 1013638032Speter way to do this, but the change is fairly major and I 1013738032Speter want to hold it for another release. Problem noted by 1013838032Speter Bret Marquis. 1013938032Speter 1014064562Sgshapiro8.5/8.5 1993/07/23 1014138032Speter Serious bug: if you used a command line recipient that was unknown 1014238032Speter sendmail would not send a return message (it was treating 1014338032Speter everything as though it had an SMTP-style client that 1014438032Speter would do the return itself). Problem noted by Josh Smith. 1014538032Speter Change "trymx" option in getcanonname() to ignore all MX data, 1014638032Speter even during a T_ANY query. This actually didn't break 1014738032Speter anything, because the only time you called getcanonname 1014838032Speter with !trymx was if you already knew there were no MX 1014938032Speter records, but it is somewhat cleaner. From Motonori 1015038032Speter Nakamura. 1015138032Speter Don't call getcanonname from getmxrr if you already know there 1015238032Speter are no DNS records matching the name. 1015338032Speter Fix a problem causing error messages to always include "The 1015438032Speter original message was received ... from localhost". 1015538032Speter The correct original host information is now included. 1015638032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 1015738032Speter version of "test" doesn't have the -x flag). Change it 1015838032Speter to use -f instead. From John Myers. 1015938032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 1016038032Speter esmtp -- it should be smtp. 1016138032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 1016238032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 1016338032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 1016438032Speter this cleans up the configs somewhat. This fixes a serious 1016538032Speter problem that caused route-addrs to get mistaken as relays, 1016638032Speter pointed out by John Myers. WARNING: this also causes 1016738032Speter the default on SMART_HOST to change from "suucp" to 1016838032Speter "relay" if you have MAILER(smtp) specified. 1016938032Speter 1017064562Sgshapiro8.4/8.4 1993/07/22 1017138032Speter Add option `w'. If you receive a message that comes to you because 1017238032Speter you are the best (lowest preference) target of an MX, and 1017338032Speter you haven't explicitly recognized the source MX host in 1017438032Speter your .cf file, this option will cause you to try the target 1017538032Speter host directly (as if there were no MX for it at all). If 1017638032Speter `w' is not set, this case is a configuration error. 1017738032Speter Beware: if `w' is set, senders may get bogus errors like 1017838032Speter "message timed out" or "host unknown" for problems that 1017938032Speter are really configuration errors. This option is 1018038032Speter disrecommended, provided only for compatibility with 1018138032Speter UIUC sendmail. 1018238032Speter Fix a problem that caused the incoming socket to be left open 1018338032Speter when sendmail forks after the DATA command. This caused 1018438032Speter calling systems to wait in FIN_WAIT_2 state until the 1018538032Speter entire list was processed and the child closed -- a 1018638032Speter potentially prodigious amount of time. Problem noted 1018738032Speter by Neil Rickert. 1018838032Speter Fix problem (created in 6.64) that caused mail sent to multiple 1018938032Speter addresses, one of which was a bad address, to completely 1019038032Speter suppress the sending of the message. This changes 1019138032Speter handling of EF_FATALERRS somewhat, and adds an 1019238032Speter EF_GLOBALERRS flag. This also fixes a potential problem 1019338032Speter with duplicate error messages if there is a syntax error 1019438032Speter in the header of a message that isn't noticed until late 1019538032Speter in processing. Original problem pointed out by Josh Smith 1019638032Speter of Harvey Mudd College. This release includes quite a bit 1019738032Speter of dickering with error handling (see below). 1019838032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 1019938032Speter will only hurt already-broken software and should help 1020038032Speter humans. 1020138032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 1020238032Speter compiled in. It would never read the alias file. 1020338032Speter Repair unbalanced `)' and `>' (the "open" versions are already 1020438032Speter repaired). 1020538032Speter Logging of "done" in dropenvelope() was incorrect: it would 1020638032Speter log this even when the queue file still existed. Change 1020738032Speter this to only log "done" (at log level 11) when the 1020838032Speter queue file is actually removed. From John Myers. 1020938032Speter Log "lost connection" in server SMTP at log level 20 if there 1021038032Speter is no pending transaction. Some senders just close the 1021138032Speter connection rather than sending QUIT. 1021238032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 1021338032Speter domains that do not have MX records -- this would cause 1021438032Speter the subsequent host name lookup to fail. The problem 1021538032Speter only occurred if you had FEATURE(nocanonify) set. 1021638032Speter Problem noted by Rick McCarty of Texas Instruments. 1021738032Speter Fix invocation of setvbuf when passed a -X flag -- I had 1021838032Speter unwittingly used an ANSI C extension, and this caused 1021938032Speter core dumps on some machines. 1022038032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 1022138032Speter Previously it just gave an empty send queue, which 1022238032Speter then gave either "Need RCPT (recipient)" at the DATA 1022338032Speter (confusing, since you had given an RCPT command which 1022438032Speter returned 250) or just dropped the email, depending on 1022538032Speter whether you were running VERBose mode. Now it usually 1022638032Speter diagnoses this case as "aliasing/forwarding loop broken". 1022738032Speter Unfortunately, it still doesn't adequately diagnose 1022838032Speter some true error conditions. 1022938032Speter Add internal concept of "warning messages" using 6xx codes. 1023038032Speter These are not reported only to Postmaster. Unbalanced 1023138032Speter parens, brackets, and quotes are printed as 653 codes. 1023238032Speter They are always mapped to 5xx codes before use in SMTP. 1023338032Speter Clean up error messages to tell both the actual address that 1023438032Speter failed and the alias they arose from. This makes it 1023538032Speter somewhat easier to diagnose problems. Difficulty noted 1023638032Speter by Motonori Nakamura. 1023738032Speter Fix a problem that inappropriately added a ctladdr to addresses 1023838032Speter that shouldn't have had one during a queue run. This 1023938032Speter caused error messages to be handled differently during 1024038032Speter a queue run than a direct run. 1024138032Speter Don't print the qf name and line number if you get errors during 1024238032Speter the direct run of the queue from srvrsmtp -- this was 1024338032Speter just extra stuff for users to crawl through. 1024438032Speter Put command line flags on second line of pid file so you can 1024538032Speter auto-restart the daemon with all appropriate arguments. 1024638032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1024738032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1024838032Speter restart it. 1024938032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1025038032Speter IDENT daemon to screw up. This required that I change 1025138032Speter HASSETEUID to HASSETREUID and complicate the mode 1025238032Speter changing somewhat because both Ultrix and SunOS seem 1025338032Speter to have a bug causing seteuid() to set the saved uid 1025438032Speter as well as the effective. The program test/t_setreuid.c 1025538032Speter will test to see if your implementation of setreuid(2) 1025638032Speter is appropriately functional. 1025738032Speter The FallBackMX (option V) handling failed to properly identify 1025838032Speter fallback to yourself -- most of the code was there, 1025938032Speter but it wasn't being enabled. Problem noted by Murray 1026038032Speter Kucherawy of the University of Waterloo. 1026138032Speter Change :include: open timeout from ETIMEDOUT to an internal 1026238032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1026338032Speter with CurHostName" in error messages, which can be 1026438032Speter confusing. Reported by Jonathan Kamens of OpenVision 1026538032Speter Technologies. 1026638032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1026738032Speter process group id. The original fix was to get around 1026838032Speter some problems with recalcitrant MUAs, but it breaks 1026938032Speter any call from a shell that creates a process group id 1027038032Speter different from the process id. I could try to fix 1027138032Speter this by diddling the tty owner (using tcsetpgrp or 1027238032Speter equivalent) but this is too likely to break other 1027338032Speter things. 1027438032Speter Portability changes: 1027538032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1027638032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1027738032Speter instead of using standard flags. Oh joy. This 1027843730Speter behavior reported by Jon Giltner of University 1027938032Speter of Colorado. 1028038032Speter SGI IRIX -- this includes several changes that should 1028138032Speter help other strict ANSI compilers. 1028238032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1028338032Speter Corporation. 1028438032Speter Solaris running the Sun C compiler (which despite the 1028538032Speter documentation apparently doesn't define 1028638032Speter __STDC__ by default). 1028738032Speter ConvexOS from Eric Schnoebelen of Convex. 1028838032Speter Sony NEWS workstations and Omron LUNA workstations from 1028938032Speter Motonori Nakamura. 1029038032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1029138032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1029238032Speter several people have made a good argument that this 1029338032Speter creates more problems than it solves (although this 1029438032Speter may prove painful in the short run). 1029538032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1029638032Speter format. 1029738032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1029838032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1029938032Speter addresses are also passed through this ruleset. 1030038032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1030138032Speter internet-style addresses would "fall off the end" of 1030238032Speter ruleset zero and be interpreted as local -- however, 1030338032Speter the angle brackets confused the recursive call. 1030438032Speter These are now diagnosed as "Unrecognized host name". 1030538032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1030638032Speter ifdef(`_MAILER_USENET_') instead of 1030738032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1030838032Speter of SINTEF RUNIT, Oslo. 1030938032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1031038032Speter early in ruleset 0; this allows .mc authors to bypass 1031138032Speter things like the "short circuit" code for local addresses. 1031238032Speter Prompted by a comment by Bill Wisner of The Well. 1031338032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1031438032Speter esmtp) to send SMTP mail. This allows you to default 1031538032Speter to esmtp but use a mailertable or other override to 1031638032Speter deal with broken servers. This logic was pointed out 1031738032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1031838032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1031938032Speter environments. Ugly as sin. 1032038032Speter 1032164562Sgshapiro8.3/8.3 1993/07/13 1032238032Speter Fix setuid problems introduced in 8.2 that caused messages 1032338032Speter like "Cannot create qfXXXXXX: Invalid argument" 1032438032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1032538032Speter involved a new compile flag "HASSETEUID" that takes 1032638032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1032738032Speter that the POSIX interface is broken enough to break 1032838032Speter some systems badly. This includes some fixes for 1032938032Speter HP-UX. Also fixes problems where the real uid is 1033038032Speter not reset properly on startup (from Neil Rickert). 1033138032Speter Fix a problem that caused timed out messages to not report the 1033238032Speter addresses that timed out. Error messages are also more 1033338032Speter "user friendly". 1033438032Speter Drop required bandwidth on connections from 64 bytes/sec to 1033538032Speter 16 bytes/sec. 1033638032Speter Further Solaris portability changes -- doesn't require the BSD 1033738032Speter compatibility library. This also adds a new 1033838032Speter "HASGETDTABLESIZE" compile flag which can be used if 1033938032Speter you want to use getdtablesize(2) instead of sysconf(2). 1034038032Speter These are loosely based on changes from David Meyer at 1034138032Speter University of Oregon. This now seems to work, at least 1034238032Speter for quick test cases. 1034338032Speter Fix a problem that can cause duplicate error messages to be 1034438032Speter sent if you are in SMTP, you send to multiple addresses, 1034538032Speter and at least one of those addresses is good and points 1034638032Speter to an account that has a .forward file (whew!). 1034738032Speter Fix a problem causing messages to be discarded if checkcompat() 1034838032Speter returned EX_TEMPFAIL (because it didn't properly mark 1034938032Speter the "to" address). Problem noted by John Myers. 1035038032Speter Fix dfopen to return NULL if the open failed; I was depending 1035138032Speter on fdopen(-1) returning NULL, which isn't the case. This 1035238032Speter isn't serious, but does result in weird error diagnoses. 1035338032Speter From Michael Corrigan. 1035438032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1035538032Speter messages sent through UUCP-family mailers. Suggested 1035638032Speter by Bill Wisner of The Well. 1035738032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1035838032Speter include a "uucp-dom" mailer that uses domain-style 1035938032Speter addressing. Suggested by Bill Wisner. 1036038032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1036138032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1036238032Speter Christophe Wolfhugel. 1036338032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1036438032Speter 1036564562Sgshapiro8.2/8.2 1993/07/11 1036638032Speter Don't drop out on config file parse errors in -bt mode. 1036738032Speter On older configuration files, assume option "l" (use Errors-To 1036838032Speter header) for back compatibility. NOTE: this DOES NOT 1036938032Speter imply an endorsement of the Errors-To: header in any way. 1037038032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1037138032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1037238032Speter SMTP server to give an error on this command, and 1037338032Speter logging it in the transcript can be confusing. Fix 1037438032Speter from Bill Wisner. 1037538032Speter IRIX compatibility changes provided by Dan Rich 1037638032Speter <drich@sandman.lerc.nasa.gov>. 1037738032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1037838032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1037938032Speter <juo@klinzhai.rutgers.edu> 1038038032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1038138032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1038238032Speter match the other flags in that file. 1038338032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1038438032Speter Save h_errno in mci struct and improve error message display. 1038538032Speter Changes from Eric Wassenaar. 1038638032Speter Open /dev/null for the transcript if the create of the xf file 1038738032Speter failed; this avoids at least one possible null pointer 1038838032Speter reference in very weird cases. From Eric Wassenaar. 1038938032Speter Clean up statistics gathering; it was over-reporting because of 1039038032Speter forks. From Eric Wassenaar. 1039138032Speter Fix problem that causes old Return-Path: line to override new 1039238032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1039338032Speter re-using old value). From Motonori Nakamura. 1039438032Speter Fix broken -m flag in K definition -- even if -m (match only) 1039538032Speter was specified, it would still replace the key with the 1039638032Speter value. Noted by Rick McCarty of Texas Instruments. 1039738032Speter If the name server timed out over several days, no "timed out" 1039838032Speter message would ever be sent back. The timeout code 1039938032Speter has been moved from markfailure() to dropenvelope() 1040038032Speter so that all such failures should be diagnosed. Pointed 1040138032Speter out by Christophe Wolfhugel and others. 1040238032Speter Relax safefile() constraints: directories in an include or 1040338032Speter forward path must be readable by self if the controlling 1040438032Speter user owns the entry, readable by all otherwise (e.g., 1040538032Speter when reading your .forward file, you have to own and 1040638032Speter have X permission in it; everyone needs X permission in 1040738032Speter the root and directories leading up to your home); 1040838032Speter include files must be readable by anyone, but need not 1040938032Speter be owned by you. 1041038032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1041138032Speter reading a .forward file; this gets around some problems 1041238032Speter on NFS mounts if root permission is not exported and 1041338032Speter the user's home directory isn't x'able. 1041438032Speter Additional NeXT portability enhancements from Axel Zinser. 1041538032Speter Additional HP-UX portability enhancements from Brian Bullen. 1041638032Speter Add a timeout around SMTP message writes; this assumes you can 1041738032Speter get throughput of at least 64 bytes/second. Note that 1041838032Speter this does not impact the "datafinal" default, which 1041938032Speter is separate; this is just intended to work around 1042038032Speter network clogs that will occur before the final dot 1042138032Speter is sent. From Eric Wassenaar. 1042238032Speter Change map code to set the "include null" flag adaptively -- 1042338032Speter it initially tries both, but if it finds anything 1042438032Speter matching without a null it never tries again with a 1042538032Speter null and vice versa. If -N is specified, it never 1042638032Speter tries without the null and creates new maps with a 1042738032Speter null byte. If -O is specified, it never tries with 1042838032Speter the null (for efficiency). If -N and -O are specified, 1042938032Speter you get -NO (get it?) lookup at all, so this would 1043038032Speter be a bad idea. If you don't specify either -N or -O, 1043138032Speter it adapts. 1043238032Speter Fix recognition of "same from address" so that MH submissions 1043338032Speter will insert the appropriate full name information; 1043438032Speter this used to work and got broken somewhere along the 1043538032Speter way. 1043638032Speter Some changes to eliminate some unnecessary SYSERRs in the 1043738032Speter log. For example, if you lost a connection, don't 1043838032Speter bother reporting that fact on the connection you lost. 1043938032Speter Add some "extended debugging" flags to try to track down 1044038032Speter why we get occasional problems with file descriptor 1044138032Speter one being closed when execing a mailer; it seems to 1044238032Speter only happen when there has been another error in the 1044338032Speter same transaction. This requires XDEBUG, defined 1044438032Speter by default in conf.h. 1044538032Speter Add "-X filename" command line flag, which logs both sides of 1044638032Speter all SMTP transactions. This is intended ONLY for 1044738032Speter debugging bad implementations of other mailers; start 1044838032Speter it up, send a message from a mailer that is failing, 1044938032Speter and then kill it off and examine the indicated log. 1045038032Speter This output is not intended to be particularly human 1045138032Speter readable. This also adds the HASSETVBUF compile 1045238032Speter flag, defaulted on if your compiler defines __STDC__. 1045338032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1045438032Speter have a local net that should get direct connects, you 1045538032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1045638032Speter See cf/README for an example. 1045738032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1045838032Speter sites that don't use the -d flag. 1045938032Speter CONFIG: hide recipient addresses as well as sender addresses 1046038032Speter behind $M if FEATURE(allmasquerade) is specified; this 1046138032Speter has been requested by several people, but can break 1046238032Speter local aliases. For example, if you mail to "localalias" 1046338032Speter this will be rewritten as "localalias@masqueradehost"; 1046438032Speter although initial delivery will work, replies will be 1046538032Speter broken. Use it sparingly. 1046638032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1046738032Speter to qualified domains in headers. I believe this is 1046838032Speter largely equivalent to the IDA feature of the same name. 1046938032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1047038032Speter to override the "system name" as your UUCP name -- 1047138032Speter in particular, to use domain-ized UUCP names. From 1047238032Speter Bill Wisner of The Well. 1047338032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1047438032Speter first. This is currently unused in the config files, 1047538032Speter but could be used in a mailertable entry. 1047638032Speter 1047764562Sgshapiro8.1C/8.1B 1993/06/27 1047838032Speter Serious security bug fix: it was possible to read any file on 1047938032Speter the system, regardless of ownership and permissions. 1048038032Speter If a subroutine returns a fully qualified address, return it 1048138032Speter immediately instead of feeding it back into rewriting. 1048238032Speter This fixes a problem with mailertable lookups. 1048338032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1048438032Speter 1048564562Sgshapiro8.1B/8.1A 1993/06/12 1048638032Speter Serious bug fix: pattern matching backup algorithm stepped by 1048738032Speter two tokens in classes instead of one. Found by Claus 1048838032Speter Assmann at University of Kiel, Germany. 1048938032Speter 1049064562Sgshapiro8.1A/8.1A 1993/06/08 1049138032Speter Another mailertable fix.... 1049238032Speter 1049364562Sgshapiro8.1/8.1 1993/06/07 1049438032Speter 4.4BSD freeze.
