Based on a 17223067Sgshapiro patch from Dr. Werner Fink of SuSE. 18223067Sgshapiro If a job is aborted using the interrupt signal (e.g., control-C from 19223067Sgshapiro the keyboard), perform minimal cleanup to avoid invoking 20223067Sgshapiro functions that are not signal-safe. Note: in previous 21223067Sgshapiro versions the mail might have been queued up already 22223067Sgshapiro and would be delivered subsequently, now an interrupt 23223067Sgshapiro will always remove the queue files and thus prevent 24223067Sgshapiro delivery. 25223067Sgshapiro Per RFC 6176, when operating as a TLS client, do not offer SSLv2. 26223067Sgshapiro Since TLS session resumption is never used as a client, disable 27223067Sgshapiro use of RFC 4507-style session tickets. 28223067Sgshapiro Work around gcc4 versions which reverse 25 years of history and 29223067Sgshapiro no longer align char buffers on the stack, breaking calls 30223067Sgshapiro to resolver functions on strict alignment platforms. 31223067Sgshapiro Found by Stuart Henderson of OpenBSD. 32223067Sgshapiro Read at most two AUTH lines from a server greeting (up to two 33223067Sgshapiro lines are read because servers may use "AUTH mechs" and 34223067Sgshapiro "AUTH=mechs"). Otherwise a malicious server may exhaust 35223067Sgshapiro the memory of the client. Bug report by Nils of MWR 36223067Sgshapiro InfoSecurity. 37223067Sgshapiro Avoid triggering an assertion in the OpenLDAP code when the 38223067Sgshapiro connection to an LDAP server is lost while making a query. 39223067Sgshapiro Problem noted and patch provided by Andy Fiddaman. 40223067Sgshapiro If ConnectOnlyTo is set and sendmail is compiled with NETINET6 41223067Sgshapiro it would try to use an IPv6 address if an IPv4 (or 42223067Sgshapiro unparseable) address is specified. 43223067Sgshapiro If SASLv2 is used, make sure that the macro {auth_authen} is 44223067Sgshapiro stored in xtext format to avoid problems with parsing 45223067Sgshapiro it. Problem noted by Christophe Wolfhugel. 46223067Sgshapiro CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing 47223067Sgshapiro -T<TMPF> that is required, but failed for some cases 48223067Sgshapiro that did not use LDAP. This change has been undone 49223067Sgshapiro until a better solution can be implemented. Problem 50223067Sgshapiro found by Andy Fiddaman. 51223067Sgshapiro CONFIG: Add cf/ostype/solaris11.m4 for Solaris11 support. 52223067Sgshapiro Contributed by Casper Dik of Oracle. 53223067Sgshapiro CONTRIB: qtool.pl: Deal with H entries that do not have a 54223067Sgshapiro letter between the question marks. Patch from 55223067Sgshapiro Stefan Christensen. 56223067Sgshapiro DOC: Use a better description for the -i option in sendmail. 57223067Sgshapiro Patch from Mitchell Berger. 58223067Sgshapiro Portability: 59223067Sgshapiro Add support for Darwin 10.x (Mac OS X 10.6). 60223067Sgshapiro Enable HAVE_NANOSLEEP for FreeBSD 3 and later. Patch 61223067Sgshapiro from John Marshall. 62223067Sgshapiro Enable HAVE_NANOSLEEP for OpenBSD 4.3 and later. 63223067Sgshapiro Use new directory "/system/volatile" for PidFile on 64223067Sgshapiro Solaris 11. Patch from Casper Dik of Oracle. 65223067Sgshapiro Fix compilation on Solaris 11 (and maybe some other 66223067Sgshapiro OSs) when using OpenSSL 1.0. Based on patch from 67223067Sgshapiro Jan Pechanec of Oracle. 68223067Sgshapiro Set SOCKADDR_LEN_T and SOCKOPT_LEN_T to socklen_t 69223067Sgshapiro for Solaris 11. Patch from Roger Faulkner of Oracle. 70223067Sgshapiro New Files: 71223067Sgshapiro cf/ostype/solaris11.m4 72223067Sgshapiro 73203004Sgshapiro8.14.4/8.14.4 2009/12/30 74203004Sgshapiro SECURITY: Handle bogus certificates containing NUL characters 75203004Sgshapiro in CNs by placing a string indicating a bad certificate 76203004Sgshapiro in the {cn_subject} or {cn_issuer} macro. Patch inspired 77203004Sgshapiro by Matthias Andree's changes for fetchmail. 78203004Sgshapiro During the generation of a queue identifier an integer overflow 79203004Sgshapiro could occur which might result in bogus characters 80203004Sgshapiro being used. Based on patch from John Vannoy of 81203004Sgshapiro Pepperdine University. 82203004Sgshapiro The value of headers, e.g., Precedence, Content-Type, et.al., 83203004Sgshapiro was not processed correctly. Patch from Per Hedeland. 84203004Sgshapiro Between 8.11.7 and 8.12.0 the length limitation on a return 85203004Sgshapiro path was erroneously reduced from MAXNAME (256) to 86203004Sgshapiro MAXSHORTSTR (203). Patch from John Gardiner Myers 87203004Sgshapiro of Proofpoint; the problem was also noted by Steve 88203004Sgshapiro Hubert of University of Washington. 89203004Sgshapiro Prevent a crash when a hostname lookup returns a seemingly 90203004Sgshapiro valid result which contains a NULL pointer (this seems 91203004Sgshapiro to be happening on some Linux versions). 92203004Sgshapiro The process title was missing the current load average when 93203004Sgshapiro the MTA was delaying connections due to DelayLA. 94203004Sgshapiro Patch from Dick St.Peters of NetHeaven. 95203004Sgshapiro Do not reset the number of queue entries in shared memory if 96203004Sgshapiro only some of them are processed. 97203004Sgshapiro Fix overflow of an internal array when parsing some replies 98203004Sgshapiro from a milter. Problem found by Scott Rotondo 99203004Sgshapiro of Sun Microsystems. 100203004Sgshapiro If STARTTLS is turned off in the server (via M=S) then it 101203004Sgshapiro would not be initialized for use in the client either. 102203004Sgshapiro Patch from Kazuteru Okahashi of IIJ. 103203004Sgshapiro If a Diffie-Hellman cipher is selected for STARTTLS, the 104203004Sgshapiro handshake could fail with some TLS implementations 105203004Sgshapiro because the prime used by the server is not long enough. 106203004Sgshapiro Note: the initialization of the DSA/DH parameters for 107203004Sgshapiro the server can take a significant amount of time on slow 108203004Sgshapiro machines. This can be turned off by setting DHParameters 109203004Sgshapiro to none or a file (see doc/op/op.me). Patch from 110203004Sgshapiro Petr Lampa of the Brno University of Technology. 111203004Sgshapiro Fix handling of `b' modifier for DaemonPortOptions on little 112203004Sgshapiro endian machines for loopback address. Patch from 113203004Sgshapiro John Beck of Sun Microsystems. 114203004Sgshapiro Fix a potential memory leak in libsmdb/smdb1.c found by parfait. 115203004Sgshapiro Based on patch from Jonathan Gray of OpenBSD. 116203004Sgshapiro If a milter sets the reply code to "421" during the transfer 117203004Sgshapiro of the body, the SMTP server will terminate the SMTP session 118203004Sgshapiro with that error to match the behavior of the other callbacks. 119203004Sgshapiro Return EX_IOERR (instead of 0) if a mail submission fails due to 120203004Sgshapiro missing disk space in the mail queue. Based on patch 121203004Sgshapiro from Martin Poole of RedHat. 122203004Sgshapiro CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would 123203004Sgshapiro cause addresses not found in LDAP to be misparsed. 124203004Sgshapiro CONFIG: Using a CN restriction did not work for TLS_Clt as it 125203004Sgshapiro referred to a wrong macro. Patch from John Gardiner 126203004Sgshapiro Myers of Proofpoint. 127203004Sgshapiro CONFIG: The option relaytofulladdress of FEATURE(`access_db') 128203004Sgshapiro did not work if FEATURE(`relay_hosts_only') is used too. 129203004Sgshapiro Problem noted by Kristian Shaw. 130203004Sgshapiro CONFIG: The internal function lower() was broken and hence 131203004Sgshapiro strcasecmp() did not work either, which could cause 132203004Sgshapiro problems for some FEATURE()s if upper case arguments 133203004Sgshapiro were used. Patch from Vesa-Matti J Kari of the 134203004Sgshapiro University of Helsinki. 135203004Sgshapiro LIBMILTER: Fix internal check whether a milter application 136203004Sgshapiro is compiled against the same version of libmilter as 137203004Sgshapiro it is linked against (especially useful for dynamic 138203004Sgshapiro libraries). 139203004Sgshapiro LIBMILTER: Fix memory leak that occurred when smfi_setsymlist() 140203004Sgshapiro was used. Based on patch by Dan Lukes. 141203004Sgshapiro LIBMILTER: Document the effect of SMFIP_HDR_LEADSPC for filters 142203004Sgshapiro which add, insert, or replace headers. From Benjamin 143203004Sgshapiro Pineau. 144203004Sgshapiro LIBMILTER: Fix error messages which refer to "select()" to be 145203004Sgshapiro correct if SM_CONF_POLL is used. Based on patch from 146203004Sgshapiro John Nemeth. 147203004Sgshapiro LIBSM: Fix handling of LDAP search failures where the error is 148203004Sgshapiro carried in the search result itself, such as seen with 149203004Sgshapiro OpenLDAP proxy servers. 150203004Sgshapiro VACATION: Do not refer to a local variable outside its scope. 151203004Sgshapiro Based on patch from Mark Costlow of Southwest Cyberport. 152203004Sgshapiro Portability: 153203004Sgshapiro Enable HAVE_NANOSLEEP for SunOS 5.11. Patch from 154203004Sgshapiro John Beck of Sun Microsystems. 155203004Sgshapiro Drop NISPLUS from default SunOS 5.11 map definitions. 156203004Sgshapiro Patch from John Beck of Sun Microsystems. 157203004Sgshapiro 158182352Sgshapiro8.14.3/8.14.3 2008/05/03 159182352Sgshapiro During ruleset processing the generation of a key for a map 160182352Sgshapiro lookup and the parsing of the default value was broken 161182352Sgshapiro for some macros, e.g., $|, which caused the BlankSub 162182352Sgshapiro character to be inserted into the workspace and thus 163182352Sgshapiro failures, e.g., rules that should have matched did not. 164182352Sgshapiro 8.14.2 caused a regression: it accessed (macro) storage which was 165182352Sgshapiro freed before. First instance of the problem reported by 166182352Sgshapiro Matthew Dillon of DragonFlyBSD; variations of the same 167182352Sgshapiro bug reported by Todd C. Miller of OpenBSD, Moritz 168182352Sgshapiro Jodeit, and Dave Hayes. 169182352Sgshapiro Improve pathname length checks for persistent host status. Patch 170182352Sgshapiro from Joerg Sonnenberger of DragonFlyBSD. 171182352Sgshapiro Reword misleading SMTP reply text for FEATURE(`badmx'). Problem 172182352Sgshapiro noted by Beth Halsema. 173182352Sgshapiro The read timeout was fixed to be Timeout.datablock if STARTTLS 174182352Sgshapiro was activated. This may cause problems if that value 175182352Sgshapiro is lowered from its default. Problem noted by Jens Elkner. 176182352Sgshapiro CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset 177182352Sgshapiro to operate incorrectly. Problem found by Werner Wiethege. 178182352Sgshapiro LIBMILTER: Omitting some protocol steps via the xxfi_negotiate() 179182352Sgshapiro callback did not work properly. The patchlevel of 180182352Sgshapiro libmilter has been set to 1 so a milter can determine 181182352Sgshapiro whether libmilter contains this fix. 182182352Sgshapiro MAKEMAP: If a delimiter is specified (-t) use that also when 183182352Sgshapiro dumping a map. Patch from Todd C. Miller of OpenBSD. 184182352Sgshapiro Portability: 185182352Sgshapiro Add support for Darwin 9.x (Mac OS X 10.5). 186182352Sgshapiro Support shared libraries in Darwin 8 and 9. Patch from 187182352Sgshapiro Chris Behrens of Concentric. 188182352Sgshapiro Add support for SCO OpenServer 6, patch from Boyd Gerber. 189203004Sgshapiro DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing slash. 190182352Sgshapiro Added Files: 191182352Sgshapiro devtools/OS/Darwin.9.x 192182352Sgshapiro devtools/OS/OSR.i386 193182352Sgshapiro 194173340Sgshapiro8.14.2/8.14.2 2007/11/01 195173340Sgshapiro If a message was queued and it contained 8 bit characters in 196173340Sgshapiro a From: or To: header, then those characters could be 197173340Sgshapiro "mistaken" for internal control characters during a queue 198173340Sgshapiro run and trigger various consistency checks. Problem 199173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 200173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 201173340Sgshapiro it is by default) then even if the Linelimit parameter 202173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 203173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 204173340Sgshapiro Myers of Proofpoint. 205173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 206173340Sgshapiro work in earlier 8.14 versions. 207173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 208173340Sgshapiro background if a milter can reject or delete a recipient. 209173340Sgshapiro Prior to 8.14 this happened only if milter could delete 210173340Sgshapiro recipients. 211173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 212182352Sgshapiro documented), not when it was reached. Patch from 213173340Sgshapiro John Beck of Sun Microsystems. 214173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 215173340Sgshapiro specified (R=0) and forking (F=f) is requested. 216173340Sgshapiro When multiple results are requested for a DNS map lookup 217173340Sgshapiro (-z and -Z), return only those that are relevant for 218173340Sgshapiro the query (not also those in the "additional section".) 219173340Sgshapiro If the message transfer time to sendmail (when acting as server) 220173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 221173340Sgshapiro the message is refused (by a milter), sendmail previously 222173340Sgshapiro created a delivery status notification (DSN). Patch 223173340Sgshapiro from Doug Heath of The Hertz Corporation. 224173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 225173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 226173340Sgshapiro Problem noted by Eliot Lear. 227173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 228173340Sgshapiro compiled in but not offered by the server and the 229173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 230173340Sgshapiro If getting the result of an LDAP query times out then close the 231173340Sgshapiro map so it will be reopened on the next lookup. This 232173340Sgshapiro should help "failover" configurations that specify more 233173340Sgshapiro than one LDAP server. 234173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 235173340Sgshapiro be triggered under some circumstances (e.g., requiring 236173340Sgshapiro a system which does not have the compile time flag 237173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 238173340Sgshapiro of National Institute of Informatics, Japan. 239173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 240173340Sgshapiro logfile entry might have been wrong. Problem found by 241173340Sgshapiro Petra Humann of TU Dresden. 242173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 243173340Sgshapiro NULL, the message body was lost. Patch from Motonori 244173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 245173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 246173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 247173340Sgshapiro replacing files. 248173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 249173340Sgshapiro reading the /etc/mail/virtusers/ directory. 250173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 251173340Sgshapiro appropriate. 252173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 253173340Sgshapiro against an older libmilter.so shared library can use an 254173340Sgshapiro 8.14 libmilter.so shared library. 255173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 256173340Sgshapiro from the version number, however, the returned value was 257173340Sgshapiro correct for the current libmilter version. 258173340Sgshapiro 259168515Sgshapiro8.14.1/8.14.1 2007/04/03 260168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 261168515Sgshapiro it in its list of recipients and deliver to it if the 262168515Sgshapiro transaction is accepted. This is a regression introduced 263168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 264168515Sgshapiro found by Andy Fiddaman. 265168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 266168515Sgshapiro could not be set in 8.14.0. 267168515Sgshapiro If a server shut down the connection in response to a STARTTLS 268168515Sgshapiro command, sendmail would log a misleading error message 269168515Sgshapiro due to an internal inconsistency. Problem found by 270168515Sgshapiro Werner Wiethege. 271168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 272168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 273168515Sgshapiro Science and Mathematics. 274168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 275168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 276168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 277168515Sgshapiro m4 options for setting MaxNOOPCommands and 278168515Sgshapiro SharedMemoryKeyFile. 279168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 280168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 281168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 282168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 283168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 284168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 285168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 286168515Sgshapiro negotiation. Problem reported by Bryan Costales. 287168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 288168515Sgshapiro Patches from Bryan Costales. 289168515Sgshapiro PORTABILITY FIXES: 290168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 291168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 292168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 293168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 294168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 295168515Sgshapiro Software Systems. 296168515Sgshapiro New Files: 297168515Sgshapiro devtools/M4/depend/QNX6.m4 298168515Sgshapiro devtools/OS/QNX.6.x 299168515Sgshapiro include/sm/os/sm_os_qnx.h 300168515Sgshapiro 301168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 302168515Sgshapiro libmilter/docs/smfi_chgfrom.html 303168515Sgshapiro libmilter/docs/smfi_version.html 304168515Sgshapiro 305168515Sgshapiro8.14.0/8.14.0 2007/01/31 306168515Sgshapiro Header field values are now 8 bit clean. Notes: 307168515Sgshapiro - header field names are still restricted to 7 bit. 308168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 309168515Sgshapiro headers. 310168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 311168515Sgshapiro number of spaces after the colon would be changed to 312168515Sgshapiro exactly one space. 313168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 314168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 315168515Sgshapiro limit may be reached too early, e.g., the counter 316168515Sgshapiro may be off by a factor of 4 in case of a sequence of 317168515Sgshapiro .forward files that refer to others. Patch from 318168515Sgshapiro Motonori Nakamura of Kyoto University. 319168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 320168515Sgshapiro "sendmail -bs" can trigger an assertion because the 321168515Sgshapiro hostname of the client is undefined. It is now set 322168515Sgshapiro to "localhost" for the xxfi_connect() callback. 323168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 324168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 325168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 326168515Sgshapiro Patch from Nik Clayton. 327168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 328168515Sgshapiro permanent errors (5xy). This can be useful for testing. 329168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 330168515Sgshapiro per daemon socket: 331168515Sgshapiro DeliveryMode DeliveryMode 332168515Sgshapiro refuseLA RefuseLA 333168515Sgshapiro delayLA DelayLA 334168515Sgshapiro queueLA QueueLA 335168515Sgshapiro children MaxDaemonChildren 336168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 337168515Sgshapiro lookup key with the LDAP escaped contents of the 338168515Sgshapiro arguments specified in the map lookup. Loosely based 339168515Sgshapiro on patch from Wolfgang Hottgenroth. 340168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 341168515Sgshapiro from Nik Clayton. 342168515Sgshapiro If a client is rejected via TCP wrapper or some other check 343168515Sgshapiro performed by validate_connection() (in conf.c) then do 344168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 345168515Sgshapiro of the University of Illinois at Urbana-Champaign. 346168515Sgshapiro If a client terminates the SMTP connection during a pause 347168515Sgshapiro introduced by greet_pause, then a misleading message 348168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 349168515Sgshapiro et.al., patch from Matej Vela. 350168515Sgshapiro New command "mstat" for control socket to provide "machine 351168515Sgshapiro readable" status. 352168515Sgshapiro New named config file rule check_eom which is called at the end 353168515Sgshapiro of a message, its parameter is the size of the message. 354168515Sgshapiro If the macro {addr_type} indicates that the current address 355168515Sgshapiro is a header address it also distinguishes between 356168515Sgshapiro recipient and sender addresses (as it is done for 357168515Sgshapiro envelope addresses). 358168515Sgshapiro When a macro is set in check_relay, then its value is accessible 359168515Sgshapiro by all transactions in the same SMTP session. 360168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 361168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 362168515Sgshapiro number of "useless" commands before the SMTP server will 363168515Sgshapiro slow down responding. 364168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 365168515Sgshapiro enabled, the MTA can be asked to select a shared memory 366168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 367168515Sgshapiro a file where to store the selected key. 368168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 369168515Sgshapiro by recognizing some commands from them. If the first command 370168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 371168515Sgshapiro connection is terminated immediately. 372168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 373168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 374168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 375168515Sgshapiro New options B, z, and Z for DNS maps: 376168515Sgshapiro -B: specify a domain that is always appended to queries. 377168515Sgshapiro -z: specify the delimiter at which to cut off the result of 378168515Sgshapiro a query if it is too long. 379168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 380168515Sgshapiro to form the result of a lookup. 381168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 382168515Sgshapiro implicitly while building libsm, they must be explicitly 383168515Sgshapiro started by using "make check". 384168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 385168515Sgshapiro reported by the SATURN tool which has been developed by 386168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 387168515Sgshapiro Fix a potential race condition caused by a signal handler for 388168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 389168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 390168515Sgshapiro queue group selection. This has been disabled as it was not 391168515Sgshapiro intended. 392168515Sgshapiro New operator 'r' for the arith map to return a random number. 393168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 394168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 395168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 396168515Sgshapiro which may improve the communication performance on some 397168515Sgshapiro operating systems. Patch from John Gardiner Myers of 398168515Sgshapiro Proofpoint. 399168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 400168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 401168515Sgshapiro generate an additional blank line in the output as the last 402168515Sgshapiro line. 403168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 404168515Sgshapiro the "queue control process" (QCP) works now. 405168515Sgshapiro Increase the length of an input line to 12288 to deal with 406168515Sgshapiro really long lines during SMTP AUTH negotiations. 407168515Sgshapiro Problem noted by Werner Wiethege. 408168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 409168515Sgshapiro a missing initialization call for that case). Problem 410168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 411168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 412168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 413168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 414168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 415168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 416168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 417168515Sgshapiro the MTA will not attempt to open a statistics file on 418168515Sgshapiro each delivery. 419168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 420168515Sgshapiro clients whose IP address does not have proper reverse DNS. 421168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 422168515Sgshapiro and John Beck of Sun Microsystems. 423168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 424168515Sgshapiro clients which provide a HELO/EHLO argument which is either 425168515Sgshapiro unqualified, or is one of our own names (i.e., the server 426168515Sgshapiro name instead of the client name). Contributed by Neil 427168515Sgshapiro Rickert of Northern Illinois University and John Beck of 428168515Sgshapiro Sun Microsystems. 429168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 430168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 431168515Sgshapiro Based on contribution from William Dell Wisner. 432168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 433168515Sgshapiro the maximum line length of the smtp mailers. 434168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 435168515Sgshapiro to allow entries in the access map to be of the form 436168515Sgshapiro To:user@example.com RELAY 437168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 438168515Sgshapiro macros a milter should receive at those stages in the 439168515Sgshapiro SMTP dialogue. 440168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 441168515Sgshapiro for the HELO/EHLO command. 442168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 443168515Sgshapiro messages by using those values as second argument. 444168515Sgshapiro Patches from Nelson Fung. 445168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 446168515Sgshapiro ignores everything after it unless it is in quotes or 447168515Sgshapiro preceeded by a backslash. 448168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 449168515Sgshapiro directories, then it used for "make install" to create 450168515Sgshapiro the required installation directories. 451168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 452168515Sgshapiro executables (defaults to confCC). 453168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 454168515Sgshapiro has several changes which are listed below and documented 455168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 456168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 457168515Sgshapiro changed. It now refers only to the version of libmilter, 458168515Sgshapiro not to the protocol version (which is used only internally, 459168515Sgshapiro it is not user/milter-programmer visible). Additionally, 460168515Sgshapiro a version function smfi_version() has been introduced such 461168515Sgshapiro that a milter program can check the libmilter version also 462168515Sgshapiro at runtime which is useful if a shared library is used. 463168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 464168515Sgshapiro dynamically (i.e., at runtime) determine the available 465168515Sgshapiro protocol actions and features of the MTA and also to 466168515Sgshapiro specify which of these a milter wants to use. This allows 467168515Sgshapiro for more flexibility than hardcoding these flags in the 468168515Sgshapiro xxfi_flags field of the smfiDesc structure. 469168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 470168515Sgshapiro can act on the DATA command. 471168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 472168515Sgshapiro can receive also unknown SMTP commands. 473168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 474168515Sgshapiro can be used by the xxfi_header() callback provided the 475168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 476168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 477168515Sgshapiro xxfi_body() callback to skip over further body chunks 478168515Sgshapiro and directly advance to the xxfi_eom() callback. This 479168515Sgshapiro is useful if a milter can make a decision based on the 480168515Sgshapiro body chunks it already received without reading the entire 481168515Sgshapiro rest of the body and the milter wants to invoke functions 482168515Sgshapiro that are only available from the xxfi_eom() callback. 483168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 484168515Sgshapiro new recipients including ESMTP parameters. 485168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 486168515Sgshapiro envelope sender including ESMTP parameters. 487168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 488168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 489168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 490168515Sgshapiro a RCPT has been rejected can be checked by comparing the 491168515Sgshapiro value of the macro {rcpt_mailer} with "error". 492168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 493168515Sgshapiro wants to receive from the MTA for each protocol step 494168515Sgshapiro by invoking the function smfi_setsymlist() during option 495168515Sgshapiro negotiation. 496168515Sgshapiro LIBMILTER: A milter can receive header field values with all 497168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 498168515Sgshapiro protocol action. Also, if the flag is set then the MTA 499168515Sgshapiro does not add a leading space to headers that are added, 500168515Sgshapiro inserted, or replaced. 501168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 502168515Sgshapiro callback, the SMTP server will terminate the SMTP session 503168515Sgshapiro with that error to match the behavior of all other callbacks. 504168515Sgshapiro New Files: 505168515Sgshapiro cf/feature/badmx.m4 506168515Sgshapiro cf/feature/block_bad_helo.m4 507168515Sgshapiro cf/feature/require_rdns.m4 508168515Sgshapiro devtools/M4/UNIX/check.m4 509168515Sgshapiro include/sm/misc.h 510168515Sgshapiro include/sm/sendmail.h 511168515Sgshapiro include/sm/tailq.h 512168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 513168515Sgshapiro libmilter/docs/smfi_setsymlist.html 514168515Sgshapiro libmilter/docs/xxfi_data.html 515168515Sgshapiro libmilter/docs/xxfi_negotiate.html 516168515Sgshapiro libmilter/docs/xxfi_unknown.html 517168515Sgshapiro libmilter/example.c 518168515Sgshapiro libmilter/monitor.c 519168515Sgshapiro libmilter/worker.c 520168515Sgshapiro libsm/memstat.c 521168515Sgshapiro libsm/t-memstat.c 522168515Sgshapiro libsm/t-qic.c 523168515Sgshapiro libsm/util.c 524168515Sgshapiro sendmail/daemon.h 525168515Sgshapiro sendmail/map.h 526168515Sgshapiro 527161389Sgshapiro8.13.8/8.13.8 2006/08/09 528161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 529161389Sgshapiro the server can erroneously report that there is 530161389Sgshapiro insufficient disk space. Additionally make sure that 531161389Sgshapiro an internal variable is set properly to avoid those 532161389Sgshapiro misleading errors. Based on patch from Steve Hubert 533161389Sgshapiro of University of Washington. 534161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 535161389Sgshapiro the process that forks the daemon exited, i.e., if 536161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 537161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 538161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 539161389Sgshapiro David F. Skoll. 540161389Sgshapiro Avoid a crash when finishing due to referencing a freed variable. 541161389Sgshapiro Problem reported and diagnosed by Moritz Jodeit. 542161389Sgshapiro CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4 543161389Sgshapiro range (0..255). 544161389Sgshapiro LIBMILTER: The "hostname" argument of the xxfi_connect() callback 545161389Sgshapiro previously was the equivalent of {client_ptr}. However, 546161389Sgshapiro this did not match the documentation of the function, hence 547161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 548161389Sgshapiro about these macros. 549161389Sgshapiro 550159609Sgshapiro8.13.7/8.13.7 2006/06/14 551159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 552159609Sgshapiro crash while trying to send a mail due to a stack overflow, 553159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 554159609Sgshapiro happens because the recursion of the function mime8to7() 555159609Sgshapiro was not restricted. The function is called for MIME 8 to 556159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 557159609Sgshapiro To work around this problem, recursive calls are limited to 558159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 559159609Sgshapiro limit is treated as opaque and is not checked further. 560159609Sgshapiro Problem noted by Frank Sheiness. 561159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 562159609Sgshapiro SASL mechanisms that use the security layer, e.g., 563159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 564159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 565159609Sgshapiro a df file might have been left behind in the queue. 566159609Sgshapiro This was another side effect of the changes to the I/O 567159609Sgshapiro layer made in 8.13.6. 568159609Sgshapiro Several minor problems have been fixed that were found by a 569159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 570159609Sgshapiro distribution. See http://scan.coverity.com/ 571159609Sgshapiro Note: the scan generated also a lot of "false positives", 572159609Sgshapiro e.g., "error" reports about situations that cannot happen. 573159609Sgshapiro Most of those code places are marked with lint(1) comments 574159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 575159609Sgshapiro Hence an explicit assertion has been added in some cases 576159609Sgshapiro to avoid those false positives. 577159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 578159609Sgshapiro error then in some cases shared memory segments or pid 579159609Sgshapiro files were not removed. 580159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 581159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 582159609Sgshapiro reported by Akihiro Sagawa. 583159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 584159609Sgshapiro bug work-around. Hence if sendmail is linked against 585159609Sgshapiro either of these versions and compression is available, 586159609Sgshapiro the padding bug work-around is turned off. Based on 587159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 588159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 589159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 590159609Sgshapiro however, that list is no longer available. To avoid 591159609Sgshapiro further problems, no default value is available anymore, 592159609Sgshapiro but an argument must be specified. 593159609Sgshapiro Portability: 594159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c.

Also fix handling of 601157001Sgshapiro a buffer in sm_syslog() which could have been used as an 602157001Sgshapiro attack vector to exploit the unsafe handling of 603157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 604157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 605157001Sgshapiro Handle theoretical integer overflows that could triggered if 606157001Sgshapiro the server accepted headers larger than the maximum 607157001Sgshapiro (signed) integer value. This is prevented in the default 608157001Sgshapiro configuration by restricting the size of a header, and on 609157001Sgshapiro most machines memory allocations would fail before reaching 610157001Sgshapiro those values. Problems found by Phil Brass of ISS. 611157001Sgshapiro If a server returns 421 for an RSET command when trying to start 612157001Sgshapiro another transaction in a session while sending mail, do 613157001Sgshapiro not trigger an internal consistency check. Problem found 614157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 615157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 616157001Sgshapiro to a STARTTLS command despite the fact that it advertised 617157001Sgshapiro STARTTLS and that the code is not valid according to RFC 618157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 619157001Sgshapiro of a protocol error (which has been changed to a 620157001Sgshapiro temporary error in 8.13.5).

This structure is used decide whether there 652157001Sgshapiro is enough free disk space when selecting a queue, hence 653157001Sgshapiro without this change queue selection could fail if a df/ 654157001Sgshapiro subdirectory exists and is on a different filesystem 655157001Sgshapiro than the base directory. 656157001Sgshapiro Use the queue index of the df file (instead of the qf file) for 657157001Sgshapiro checking whether a link(2) operation can be used to split 658157001Sgshapiro an envelope across queue groups. Problem found by 659157001Sgshapiro Werner Wiethege. 660157001Sgshapiro If the list of items in the queue is larger than the maximum 661157001Sgshapiro number of items to process, sort the queue first and 662157001Sgshapiro then cut the list off instead of the other way around. 663157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 664157001Sgshapiro Fix helpfile to show full entry for ETRN. Problem noted by 665157001Sgshapiro Penelope Fudd, patch from Neil Rickert of Northern Illinois 666157001Sgshapiro University. 667157001Sgshapiro FallbackSmartHost should also be tried on temporary errors. 668157001Sgshapiro From John Beck of Sun Microsystems. 669157001Sgshapiro When a server responds with 421 to the STARTTLS command then treat 670157001Sgshapiro it as a temporary error, not as protocol error. Problem 671157001Sgshapiro noted by Andrey J. Melnikoff. 672157001Sgshapiro Properly define two functions in libsm as static because their 673157001Sgshapiro prototype used static too. Patch from Peter Klein. 674157001Sgshapiro Fix syntax errors in helpfile for MAIL and RCPT commands. 675157001Sgshapiro LIBMILTER: When smfi_replacebody() is called with bodylen equals 676157001Sgshapiro zero then do not silently ignore that call. Patch from 677157001Sgshapiro Gurusamy Sarathy of Active State. 678157001Sgshapiro LIBMILTER: Recognize "421" also in a multi-line reply to terminate 679157001Sgshapiro the SMTP session with that error. Fix from Brian Kantor. 680157001Sgshapiro Portability: New option HASSNPRINTF which can be set if the OS 681157001Sgshapiro has a properly working snprintf(3) to get rid 682157001Sgshapiro of the last two (safe) sprintf(3) calls in the 683157001Sgshapiro source code. 684157001Sgshapiro Add support for AIX 5.3. 685157001Sgshapiro Add support for SunOS 5.11 (aka Solaris 11). 686157001Sgshapiro Add support for Darwin 8.x.

Problem noted by Michael Sims. 711147078Sgshapiro Deal with empty hostnames in hostsignature(). This bug could lead 712147078Sgshapiro to an endless loop when doing LMTP deliveries to another 713147078Sgshapiro host. Problem first reported by Martin Lathoud and 714147078Sgshapiro tracked down by Gael Roualland. 715147078Sgshapiro Make sure return parameters are initialized in getmxrr(). Problem 716147078Sgshapiro found by Gael Roualland using valgrind. 717147078Sgshapiro If shared memory is used and the RunAsUser option is set, then the 718161389Sgshapiro owner and group of the shared memory segment is set to 719147078Sgshapiro the ids specified RunAsUser and the access mode is set 720147078Sgshapiro to 0660 to allow for updates by sendmail processes. 721147078Sgshapiro The number of queue entries that is (optionally) kept in shared 722147078Sgshapiro memory was wrong in some cases, e.g., envelope splitting 723147078Sgshapiro and bounce generation. 724147078Sgshapiro Undo a change made in 8.13.0 to silently truncate long strings 725147078Sgshapiro in address rewriting because the message can be triggered 726147078Sgshapiro for header checks where long strings are legitimate. 727147078Sgshapiro Problem reported by Mary Verge DeSisto, and tracked 728147078Sgshapiro down with the help of John Beck of Sun Microsystems. 729147078Sgshapiro The internal stab map did not obey the -m flag. Patch from 730147078Sgshapiro Rob McMahon of Warwick University, England. 731147078Sgshapiro The socket map did not obey the -f flag. Problem noted by 732147078Sgshapiro Dan Ringdahl, forwarded by Andrzej Filip. 733147078Sgshapiro The addition of LDAP recursion in 8.13.0 broke enforcement of 734147078Sgshapiro the LDAP map -1 argument which tells the MTA to only 735147078Sgshapiro return success if and only if a single LDAP match is found. 736147078Sgshapiro Add additional error checks in the MTA for milter communication 737147078Sgshapiro to avoid a possible segmentation fault. Based on patch 738147078Sgshapiro by Joe Maimon. 739147078Sgshapiro Do not trigger an assertion if X509_digest() returns success but 740147078Sgshapiro does not assign a value to its output parameter. Based 741147078Sgshapiro on patch by Brian Kantor. 742147078Sgshapiro Add more checks when resetting internal AUTH data (applies only 743147078Sgshapiro to Cyrus SASL version 2). Otherwise an SMTP session might 744147078Sgshapiro be dropped after an AUTH failure. 745147078Sgshapiro Portability: 746147078Sgshapiro Add LA_LONGLONG as valid LA_TYPE type for systems that use 747147078Sgshapiro "long long" to read load average data, e.g., 748147078Sgshapiro AIX 5.1 in 32 bit mode. Note: this has to be set 749147078Sgshapiro "by hand", it is not (yet) automatically detected. 750147078Sgshapiro Problem noted by Burak Bilen. 751147078Sgshapiro Use socklen_t for accept(), etc. on AIX 5.x. This should 752147078Sgshapiro fix problems when compiling in 64 bit mode. 753147078Sgshapiro Problem first reported by Harry Meiert of 754147078Sgshapiro University of Bremen. 755147078Sgshapiro New Files: 756147078Sgshapiro include/sm/sem.h 757147078Sgshapiro libsm/sem.c 758147078Sgshapiro libsm/t-sem.c 759147078Sgshapiro 760141858Sgshapiro8.13.3/8.13.3 2005/01/11 761141858Sgshapiro Enhance handling of I/O errors, especially EOF, when STARTTLS 762141858Sgshapiro is active. 763141858Sgshapiro Make sure a connection is not reused after it has been closed 764141858Sgshapiro due to a 421 error.

Problem found by Allan E Johannesen 768141858Sgshapiro of Worcester Polytechnic Institute. 769141858Sgshapiro Regression: a change in 8.13.2 caused sendmail not to try the 770141858Sgshapiro next MX host (or FallbackMXhost if configured) when, at 771141858Sgshapiro connection open, the current server returns a 4xy or 5xy 772141858Sgshapiro SMTP reply code. Problem noted by Mark Tranchant. 773141858Sgshapiro 774141858Sgshapiro8.13.2/8.13.2 2004/12/15 775141858Sgshapiro Do not split the first header even if it exceeds the internal 776141858Sgshapiro buffer size. Previously a part of such a header would 777141858Sgshapiro end up in the body of the message. Problem noted by 778141858Sgshapiro Simple Nomad of BindView. 779141858Sgshapiro Do not complain about "cataddr: string too long" when checking 780141858Sgshapiro headers that do not contain RFC 2822 addresses. 781141858Sgshapiro Problem noted by Rich Graves of Brandeis University. 782141858Sgshapiro If a server returns a 421 reply to the RSET command between 783141858Sgshapiro message deliveries, do not attempt to deliver any more 784141858Sgshapiro messages on that connection. This prevents bogus "Bad 785141858Sgshapiro file number" recipient status. Problem noted by 786141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 787141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 788141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 789141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 790141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 791141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 792141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 793141858Sgshapiro them off at a comma. Problem noted by Krzysztof Oledzki. 794141858Sgshapiro Add more logging to milter change header functions to 795141858Sgshapiro complement existing logging.

This allows 879132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 880132943Sgshapiro URL which will in turn be queried. See the ``LDAP 881132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 882132943Sgshapiro Based on patch from Andrew Baucom. 883132943Sgshapiro Extend the default LDAP specifications for AliasFile 884132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 885132943Sgshapiro include support for LDAP recursion via new attributes. 886132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 887132943Sgshapiro of cf/README for more information. 888132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 889132943Sgshapiro LDAP API/protocol version to use. The default depends on 890132943Sgshapiro the LDAP library. 891132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 892132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 893132943Sgshapiro and -p port. This also allows for the use of LDAP over 894132943Sgshapiro SSL and connections via named sockets if your LDAP 895132943Sgshapiro library supports it. 896132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 897132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 898132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 899132943Sgshapiro during a SMTP session then terminate it just like it is 900132943Sgshapiro done for too many bad SMTP commands. 901132943Sgshapiro Basic connection rate control support has been added: the daemon 902132943Sgshapiro maintains the number of incoming connections per client 903132943Sgshapiro IP address and total in the macros {client_rate} and 904132943Sgshapiro {total_rate}, respectively. These macros can be used 905132943Sgshapiro in the cf file to impose connection rate limits. 906132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 907132943Sgshapiro determines the length of the interval for which the 908132943Sgshapiro number of connections is stored. Based on patch from 909132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 910132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 911132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 912132943Sgshapiro If enabled by the new ruleset greet_pause (see 913132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 914132943Sgshapiro amount of time before sending the initial 220 SMTP 915132943Sgshapiro greeting. If any traffic is received before then, a 554 916132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 917132943Sgshapiro during that connection. 918132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 919132943Sgshapiro server could sleep for a very long time. Fix based on 920132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 921132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 922132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 923132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 924132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 925132943Sgshapiro misinterpret it as a permanent error. 926132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 927132943Sgshapiro all milters accepted the mail. This can increase 928132943Sgshapiro performance if many mails are rejected by milters due to 929132943Sgshapiro body scans. Based on patch from David F. Skoll. 930132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 931132943Sgshapiro header, whether provided by the client or generated by 932132943Sgshapiro sendmail. 933132943Sgshapiro New macro {client_connections} which contains the number of open 934132943Sgshapiro connections in the SMTP server for the client IP address. 935132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 936132943Sgshapiro Mines de Paris. 937132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 938132943Sgshapiro to prevent confusion caused by running sendmail stop 939132943Sgshapiro scripts two or more times, where the second and subsequent 940141858Sgshapiro runs would report misleading error messages about sendmail's 941132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 942132943Sgshapiro for a discussion of the implications of this, including 943132943Sgshapiro how to correct broken scripts which may have depended on 944132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 945132943Sgshapiro Support per-daemon input filter lists which override the default 946132943Sgshapiro filter list specified in InputMailFilters. The filters 947132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 948132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 949132943Sgshapiro your configuration relies on this behavior, you have to 950132943Sgshapiro add those names to class 'w' yourself. Problem noted 951132943Sgshapiro by Sander Eerkes. 952132943Sgshapiro Support message quarantining in the mail queue. Quarantined 953132943Sgshapiro messages are not run on normal queue displays or runs 954132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 955132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 956132943Sgshapiro The -q command line option now can specify which queue to display 957132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 958132943Sgshapiro operates on lost queue items. 959132943Sgshapiro Restricted mail queue runs and displays can be done based on the 960132943Sgshapiro quarantined reason using -qQtext to run or display 961132943Sgshapiro quarantined items if the quarantine reason contains the 962132943Sgshapiro given text. Similarly, -q!Qtext will run or display 963132943Sgshapiro quarantined items which do not have the given text in the 964132943Sgshapiro quarantine reason. 965132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 966132943Sgshapiro new -Q option. See doc/op/op.me for more information. 967132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 968132943Sgshapiro quarantine reason is shown in a new line prefixed by 969132943Sgshapiro "QUARANTINE:". 970132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 971132943Sgshapiro to quarantine messages in check_* (except check_compat) and 972132943Sgshapiro header check rulesets. The $: of the mailer triplet will 973132943Sgshapiro be used for the quarantine reason. 974132943Sgshapiro Add a new quarantine count to the mailstats collected. 975132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 976132943Sgshapiro message if it is quarantined. 977132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 978132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 979132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 980132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 981132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 982132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 983132943Sgshapiro lookup for the client IP address. Note: this is the same 984132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 985132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 986132943Sgshapiro recipients received so far in a transaction. 987132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 988132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 989132943Sgshapiro noted by Kai Schlichting. 990132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 991132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 992132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 993132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 994132943Sgshapiro Wolfhugel of France Telecom Oleane. 995132943Sgshapiro Do not silently truncate long strings in address rewriting. 996132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 997132943Sgshapiro Oceana Matrix Ltd. 998132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 999132943Sgshapiro support mutual authentication. From Kenneth Murchison of 1000132943Sgshapiro Oceana Matrix Ltd. 1001132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 1002132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 1003132943Sgshapiro format just like the STARTTLS related macros to avoid 1004132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 1005132943Sgshapiro Masarati of SysNet s.n.c. 1006132943Sgshapiro New option AuthRealm to set the authentication realm that is 1007132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 1008132943Sgshapiro of the University of Manitoba. 1009132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 1010132943Sgshapiro successful, otherwise relaying would be allowed if 1011132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 1012132943Sgshapiro is active. 1013132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 1014132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 1015132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 1016132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 1017132943Sgshapiro DIGEST-MD5 and LOGIN. 1018132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 1019132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 1020132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 1021132943Sgshapiro overwrite each other's pid files. 1022132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 1023132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 1024132943Sgshapiro Wolfhugel of France Telecom. 1025132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 1026132943Sgshapiro LogLevel 12 or higher. 1027132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 1028132943Sgshapiro try to use the SMTP command VERB to propagate this option 1029132943Sgshapiro to the MTA which in turn will show the delivery just like 1030132943Sgshapiro it was done before the default 8.12 separation of MSP and 1031132943Sgshapiro MTA. Based on patch by Per Hedeland. 1032132943Sgshapiro If a daemon is refusing connections for longer than the time specified 1033132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 1034132943Sgshapiro to high load, log this information. Patch from John Beck 1035132943Sgshapiro of Sun Microsystems. 1036132943Sgshapiro Remove the ability for non-trusted users to raise the value of 1037132943Sgshapiro CheckpointInterval on the command line. 1038132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 1039132943Sgshapiro subset of the functionality of the 's' flag. 1040132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 1041132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 1042132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 1043132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 1044132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 1045132943Sgshapiro causing subsequent messages to be sent instead of being 1046132943Sgshapiro discarded. This also caused milter callbacks to be called 1047132943Sgshapiro out of order after the SMTP session was reset. 1048132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 1049132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 1050132943Sgshapiro further information. 1051132943Sgshapiro New command line option -D logfile to send debug output to 1052132943Sgshapiro the indicated log file instead of stdout. 1053132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 1054132943Sgshapiro queue return and warning times for delivery status 1055132943Sgshapiro notifications. 1056132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 1057132943Sgshapiro at all. 1058132943Sgshapiro Several more return values for ruleset srv_features have been added 1059132943Sgshapiro to enable/disable certain features in the server per 1060132943Sgshapiro connection. See doc/op/op.me for details. 1061132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 1062132943Sgshapiro for DaemonPortOptions. 1063132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 1064132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 1065132943Sgshapiro of Northern Illinois University. 1066132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 1067132943Sgshapiro be tried as a last resort after all other fallbacks. This 1068132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 1069132943Sgshapiro view of inside the company, but an incomplete view of 1070132943Sgshapiro outside). From John Beck of Sun Microsystems. 1071132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 1072132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 1073132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 1074132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 1075132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 1076132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 1077132943Sgshapiro of the University of Illinois at Urbana-Champaign. 1078132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 1079132943Sgshapiro applications for use in the xxfi_eom() callback. 1080132943Sgshapiro New macro {time} which contains the output of the time(3) function, 1081132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 1082132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 1083132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 1084132943Sgshapiro terminate the SMTP session with a 421 error message. 1085132943Sgshapiro Get rid of dead code that tried to access the environment variable 1086132943Sgshapiro HOSTALIASES. 1087132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 1088132943Sgshapiro compile with -DUSE_TTYPATH=1. 1089132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 1090132943Sgshapiro the header value passed in without balancing quotes, 1091132943Sgshapiro parentheses, and angle brackets. Based on patch from 1092132943Sgshapiro Oleg Bulyzhin. 1093132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 1094132943Sgshapiro angle brackets when reading in rulesets. This allows 1095132943Sgshapiro rules to be written for header checks to catch strings 1096132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 1097132943Sgshapiro Based on patch from Oleg Bulyzhin. 1098132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 1099132943Sgshapiro some temporary errors like ECONNABORTED. 1100132943Sgshapiro Added list of CA certificates that are used by members of the 1101132943Sgshapiro sendmail consortium, see CACerts. 1102132943Sgshapiro Portability: 1103132943Sgshapiro Two new compile options have been added: 1104132943Sgshapiro HASCLOSEFROM System has closefrom(3). 1105132943Sgshapiro HASFDWALK System has fdwalk(3). 1106132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 1107132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 1108132943Sgshapiro change to using fcntl() locking until they can fix 1109132943Sgshapiro it. Be sure to update other sendmail related 1110132943Sgshapiro programs to match locking techniques. 1111132943Sgshapiro New compile time option NEEDINTERRNO which should be set 1112132943Sgshapiro if <errno.h> does not declare errno itself. 1113132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 1114132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 1115132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 1116132943Sgshapiro Center for Scientific Computing. 1117132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 1118132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 1119132943Sgshapiro Remove path from compiler definition for Interix because 1120132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 1121132943Sgshapiro Also use <sys/mkdev.h> to get the correct 1122132943Sgshapiro major()/minor() definitions. Based on feedback 1123132943Sgshapiro from Mark Funkenhauser. 1124132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 1125132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 1126132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 1127132943Sgshapiro cf/sendmail.schema for more information. 1128132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 1129132943Sgshapiro is of the form "user:group" when used for submit.mc. 1130132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 1131132943Sgshapiro of Northern Illinois University. 1132132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 1133132943Sgshapiro instructs the check_* (except check_compat) to quarantine 1134132943Sgshapiro the message using the given reason. 1135132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 1136132943Sgshapiro instead of "host" to avoid problem with looking up other 1137132943Sgshapiro DNS records than just A. 1138132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 1139132943Sgshapiro length of the interval for which the number of incoming 1140132943Sgshapiro connections is maintained. 1141132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 1142132943Sgshapiro rate control for individual hosts or nets. 1143132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 1144132943Sgshapiro number of open SMTP connections for individual hosts or nets. 1145132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 1146132943Sgshapiro slamming protection described above. The feature can 1147132943Sgshapiro take an argument specifying the milliseconds to wait and/or 1148132943Sgshapiro use the access database to look the pause time based on 1149132943Sgshapiro client hostname, domain, IP address, or subnet. 1150132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 1151132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 1152132943Sgshapiro rejections based on the unverified hostname of client, 1153132943Sgshapiro which turns on the same behavior as in earlier sendmail 1154132943Sgshapiro versions when delay_checks was not in use. See also entry 1155132943Sgshapiro above about check_relay being invoked with ${client_name}. 1156132943Sgshapiro CONFIG: New option confREJECT_LOG_INTERVAL to specify the log 1157132943Sgshapiro interval when refusing connections for this long. 1158132943Sgshapiro CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases 1159132943Sgshapiro this requires a change in a mc file. Requested by 1160132943Sgshapiro Ted Roberts of Electronic Data Systems. 1161132943Sgshapiro CONFIG: New option confAUTH_REALM to set the authentication realm 1162132943Sgshapiro that is passed to the Cyrus SASL library. Patch from 1163132943Sgshapiro Gary Mills of the University of Manitoba. 1164132943Sgshapiro CONFIG: Rename the (internal) classes {tls}/{src} to {Tls}/{Src} 1165132943Sgshapiro to follow the naming conventions. 1166132943Sgshapiro CONFIG: Add a third optional argument to local_lmtp to specify 1167132943Sgshapiro the A= argument. 1168132943Sgshapiro CONFIG: Remove the f flag from the default mailer flags of 1169132943Sgshapiro local_lmtp. 1170132943Sgshapiro CONFIG: New option confREQUIRES_DIR_FSYNC to turn off the compile 1171132943Sgshapiro time flag REQUIRES_DIR_FSYNC at runtime. 1172132943Sgshapiro CONFIG: New LOCAL_UUCP macro to insert rules into the generated 1173132943Sgshapiro cf file at the same place where MAILER(`uucp') inserts 1174132943Sgshapiro its rules. 1175132943Sgshapiro CONFIG: New options confTO_QUEUERETURN_DSN and confTO_QUEUEWARN_DSN 1176132943Sgshapiro to control queue return and warning times for delivery 1177132943Sgshapiro status notifications. 1178132943Sgshapiro CONFIG: New option confFALLBACK_SMARTHOST to define FallbackSmartHost. 1179132943Sgshapiro CONFIG: Add the mc file which has been used to create the cf 1180132943Sgshapiro file to the end of the cf file when using make in cf/cf/. 1181132943Sgshapiro Patch from Richard Rognlie. 1182132943Sgshapiro CONFIG: FEATURE(nodns) has been removed, it was a no-op since 8.9. 1183132943Sgshapiro Use ServiceSwitchFile to turn off DNS lookups, see 1184132943Sgshapiro doc/op/op.me. 1185132943Sgshapiro CONFIG: New option confMILTER_MACROS_EOM (sendmail Milter.macros.eom 1186132943Sgshapiro option) defines macros to be sent to milter applications for 1187132943Sgshapiro use in the xxfi_eom() callback. 1188132943Sgshapiro CONFIG: New option confCRL to specify file which contains 1189132943Sgshapiro certificate revocations lists. 1190132943Sgshapiro CONFIG: Add a new value (sendertoo) for the third argument to 1191132943Sgshapiro FEATURE(`ldap_routing') which will reject the SMTP 1192132943Sgshapiro MAIL From: command if the sender address doesn't exist 1193132943Sgshapiro in LDAP. See cf/README for more information. 1194132943Sgshapiro CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which 1195132943Sgshapiro instructs the rulesets on whether or not to do a domain 1196132943Sgshapiro lookup if a full address lookup doesn't match. See cf/README 1197132943Sgshapiro for more information. 1198132943Sgshapiro CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which 1199132943Sgshapiro instructs the rulesets on whether or not to queue the mail 1200132943Sgshapiro or give an SMTP temporary error if the LDAP server can't be 1201132943Sgshapiro reached. See cf/README for more information.

Problem noted by Andrzej Filip. 1321125820Sgshapiro Some ident responses contain data after the terminating CRLF which 1322125820Sgshapiro causes sendmail to log "POSSIBLE ATTACK...newline in string". 1323125820Sgshapiro To avoid this everything after LF is ignored. 1324125820Sgshapiro If the operating system supports O_EXLOCK and HASFLOCK is set 1325125820Sgshapiro then a possible race condition for creating qf files 1326125820Sgshapiro can be avoided. Note: the race condition does not 1327125820Sgshapiro exist within sendmail, but between sendmail and an 1328125820Sgshapiro external application that accesses qf files. 1329125820Sgshapiro Log the proper options name for TLS related mising files for 1330125820Sgshapiro the CACertPath, CACertFile, and DHParameters options. 1331125820Sgshapiro Do not split an envelope if it will be discarded, otherwise df 1332125820Sgshapiro files could be left behind.

This change has been made to 1640102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 1641102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 1642102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1643102528Sgshapiro modification causes a change of behavior if an IP net/address 1644102528Sgshapiro is listed in the access map with REJECT and a host/domain 1645102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1646102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1647102528Sgshapiro change was made on request of Neil Rickert of Northern 1648102528Sgshapiro Illinois University, the side effect has been found by 1649102528Sgshapiro Stefaan Van Hoornick. 1650102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1651102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1652102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1653102528Sgshapiro University. 1654102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1655102528Sgshapiro Fix from Andrzej Filip. 1656102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1657102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1658102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1659102528Sgshapiro NULL pointer.

In previous versions this could cause mail 179694334Sgshapiro not to be delivered if a queue file is repeatedly moved 179794334Sgshapiro by an external process whenever sendmail moved it back 179894334Sgshapiro into the right place. Some precautions have been taken 179994334Sgshapiro to avoid moving queue files if not really necessary. 180094334Sgshapiro sendmail may use links to refer to queue files and it 180194334Sgshapiro may store the path of data files in queue files. Hence 180294334Sgshapiro queue files should not be moved unless those internals 180394334Sgshapiro are understood and the integrity of the files is not 180494334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 180594334Sgshapiro University. 180694334Sgshapiro If an error mail is created, and the mail is split across different 180794334Sgshapiro queue directories, and SuperSafe is off, then write the mail 180894334Sgshapiro to disk before splitting it, otherwise an assertion is 180994334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 181094334Sgshapiro of INTERMETA. 181194334Sgshapiro Fix possible race condition that could cause sendmail to forget 181294334Sgshapiro running queues.

Based on patch from Dirk Meyer 182594334Sgshapiro of Dinoex. 182694334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 182794334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 182894334Sgshapiro Polytechnic Institute. 182994334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 183094334Sgshapiro if several mails are sent in one session and some of them 183194334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 183294334Sgshapiro Change timeout check such that cached information about a connection 183394334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 183494334Sgshapiro Based on patch from David Burns of Portland State University. 183594334Sgshapiro Properly count message size for mailstats during mail collection. 183694334Sgshapiro Problem noted by Werner Wiethege. 183794334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 1838168515Sgshapiro patch from Motonori Nakamura of Kyoto University. 183994334Sgshapiro Provide workaround for getopt() implementations that do not catch 184094334Sgshapiro missing arguments. 184194334Sgshapiro Fix the message size calculation if the message body is replaced by 184294334Sgshapiro a milter filter and buffered file I/O is being used. 184394334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 184494334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 184594334Sgshapiro Problem noted by Werner Wiethege. 184694334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 184794334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 184894334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 184994334Sgshapiro Properly deal with a case where sendmail is called by root running 185094334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 185194334Sgshapiro Lusky of ISS Atlanta. 185294334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 185394334Sgshapiro directories are used and mail is sent to a mailing list 185494334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 185594334Sgshapiro of Concordia University. 185694334Sgshapiro Fix class map parsing code if optional key is specified. Problem 185794334Sgshapiro found by Mario Nigrovic. 185894334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 185994334Sgshapiro incoming messages. A leading dot is always stripped by the 186094334Sgshapiro SMTP receiver regardless of whether or not it is followed by 186194334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 186294334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 186394334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 186494334Sgshapiro Elvers. 186594334Sgshapiro Correct the statistics gathered for total number of connections. 186694334Sgshapiro Instead of being the exact same number as the total number 186794334Sgshapiro of messages (T line in mailstats) it now represents the 186894334Sgshapiro total number of TCP connections. 186994334Sgshapiro Be more explicit about syntax errors in addresses, especially 187094334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 187194334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 187294334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 187394334Sgshapiro are used.

Based on 188194334Sgshapiro patch by Bryan Costales. 188294334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 188394334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 188494334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 188594334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 188694334Sgshapiro errors. By doing so, the host was marked as having a 188794334Sgshapiro temporary problem and other mail destined for that host was 188894334Sgshapiro queued for the next queue run. Problem noted by Fletcher 188994334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 189094334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 189194334Sgshapiro and Neil Rickert of Northern Illinois University. 189294334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 189394334Sgshapiro which drop the connection instead of responding to the 189494334Sgshapiro command). 189594334Sgshapiro Portability: 189694334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 189798121Sgshapiro available. 189894334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 189994334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 190094334Sgshapiro settings. Patch from Elias Halldor Agustsson of 190194334Sgshapiro Skyrr. 190294334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 190394334Sgshapiro noted by John Beck. 190494334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 190594334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 190694334Sgshapiro Rajesh Somasund of Hewlett-Packard. 190794334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 190894334Sgshapiro SMTP AUTH information. This feature was actually added in 190994334Sgshapiro 8.12.0 but a release note was not included. 191094334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 191194334Sgshapiro parameter is set and the LDAP lookup returns a temporary 191294334Sgshapiro error. 191394334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 191494334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 191594334Sgshapiro Krzysztof Oledzki. 191694334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 191794334Sgshapiro initialization as aliases are not needed for the MSP. 191894334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 191994334Sgshapiro is in use. Patch from Andrzej Filip. 192094334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 192194334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 192294334Sgshapiro This will only have an effect if a parameter is specified, 192394334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 192494334Sgshapiro it is embedded in square brackets. Problem noted by 192594334Sgshapiro Theo Van Dinter of Collective Technologies. 192694334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 192794334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 192894334Sgshapiro to allow for the proper time zone on systems where the 192994334Sgshapiro default results in misleading time stamps. That is, syslog 193094334Sgshapiro time stamps and Date headers on submitted mail will use the 193194334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 193294334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 193394334Sgshapiro by Neil Rickert of Northern Illinois University. 193494334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 193594334Sgshapiro binary.

Colburn of the New Mexico 198690792Sgshapiro Institute of Mining and Technology. 198790792Sgshapiro Only log milter body replacements once instead of for each body 198890792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 198990792Sgshapiro the Finnish Meteorological Institute. 199090792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 199190792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 199290792Sgshapiro of the Finnish Meteorological Institute. 199390792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 199490792Sgshapiro needs to collect children status to avoid zombie processes. 199590792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 199690792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 199790792Sgshapiro commands are issued. This makes it consistent with normal 199890792Sgshapiro SMTP connections. 199990792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 200090792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 200190792Sgshapiro and Technology. 200290792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 200390792Sgshapiro message sender if the sender had used a deprecated RFC822 200490792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 200590792Sgshapiro Meteorological Institute. 200690792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 200790792Sgshapiro parsing.

Add configuration options for 213190792Sgshapiro different set*gid() calls to reset saved gid. Problem 213290792Sgshapiro found by Michal Zalewski. 213390792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 213490792Sgshapiro privileges by disabling debugging (command line -d flag) 213590792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 213690792Sgshapiro used. Suggested by Michal Zalewski. 213790792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 213890792Sgshapiro Problem found by Michal Zalewski. 213990792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 214090792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 214190792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 214290792Sgshapiro If debugging is turned on (-d0.10) print not just the default 214390792Sgshapiro values for configuration file and pid file but also the 214490792Sgshapiro selected values. Problem noted by Brad Chapman. 214590792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 214690792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 214790792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 214890792Sgshapiro this only applied to hostname canonification. Problem 214990792Sgshapiro noted by Bill Fenner of AT&T Research. 215090792Sgshapiro Ignore comments in NIS host records when trying to find the 215190792Sgshapiro canonical name for a host. 215290792Sgshapiro When sendmail has extra privileges, limit mail submission command 215390792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 215490792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 215590792Sgshapiro suggestion from Michal Zalewski. 215690792Sgshapiro Portability: 215790792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 215890792Sgshapiro `uname` does not given complete information. 215990792Sgshapiro Problem noted by Keith Neufeld of the Cessna 216090792Sgshapiro Aircraft Company. 216190792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 216290792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 216390792Sgshapiro Avoid compiler warnings by not using pointers to pass 216490792Sgshapiro integers.

You need to create a new user and 219790792Sgshapiro a new group before installing sendmail (both called smmsp by 219890792Sgshapiro default). The installation process tries to install 219990792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 220090792Sgshapiro default.

Suggested 221190792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 221290792Sgshapiro (IdS). 221390792Sgshapiro Fixed problem of a global variable being used for a timeout jump 221490792Sgshapiro point where the variable could become overused for more than 221590792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 221690792Sgshapiro a corrupted stack causing a core dump. The timeout is now 221790792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 221890792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 221990792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 222090792Sgshapiro checks (group ID of RunAsUser). This allows use of a 222190792Sgshapiro set-group-ID sendmail binary for initial message submission 222290792Sgshapiro and no set-user-ID root sendmail is needed. For details 222390792Sgshapiro see sendmail/SECURITY. 222490792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 222590792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 222690792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 222790792Sgshapiro with a fallback of sendmail.cf as configuration file. See 222890792Sgshapiro sendmail/SECURITY. 222990792Sgshapiro New configuration file option UseMSP to allow group writable queue 223090792Sgshapiro files if the group is the same as that of a set-group-ID 223190792Sgshapiro sendmail binary. See sendmail/SECURITY. 223290792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 223390792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 223490792Sgshapiro is sendmail.cf (to be backward compatible). This selection 223590792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 223690792Sgshapiro file: client or mta). See sendmail/SECURITY. 223790792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 223890792Sgshapiro command has been removed. 223990792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 224090792Sgshapiro at compile time or per host (ruleset). 224190792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 224290792Sgshapiro used to look up local mail recipients; the default value 224390792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 224490792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 224590792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 224690792Sgshapiro long, to accomodate envelope splitting. File systems with 224790792Sgshapiro a 14 character file name length limit are no longer 224890792Sgshapiro supported. 224990792Sgshapiro Recipient list used for delivery now gets internally ordered by 225090792Sgshapiro hostsignature (character string version of MX RR). This orders 225190792Sgshapiro recipients for the same MX RR's together meaning smaller 225290792Sgshapiro portions of the list need to be scanned (instead of the whole 225390792Sgshapiro list) each delivery() pass to determine piggybacking. The 225490792Sgshapiro significance of the change is better the larger the recipient 225590792Sgshapiro list. Hostsignature is now created during recipient list 225690792Sgshapiro creation rather than just before delivery. 225790792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 225890792Sgshapiro piggybacking (called coincidental) extended to coattail 225990792Sgshapiro piggybacking. Rather than complete MX RR matching 226090792Sgshapiro (coincidental) piggybacking is done if just the lowest value 226190792Sgshapiro preference matches (coattail). 226290792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 226390792Sgshapiro try other MX hosts if available. 226490792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 226590792Sgshapiro outgoing (client-side) SMTP Authentication. 226690792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 226790792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 226890792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 226990792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 227090792Sgshapiro A new ruleset authinfo can be used to return client side 227190792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 227290792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 227390792Sgshapiro removed in future versions. 227490792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 227590792Sgshapiro requires 334. Mercury 1.48 is a known offender. 227690792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 227790792Sgshapiro for the security layer in SMTP AUTH (SASL). See 227890792Sgshapiro doc/op/op.me for details. 227990792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 228090792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 228190792Sgshapiro signed the presented certificate, the CN and the MD5 hash 228290792Sgshapiro of the presented certificate, respectively. 228390792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 228490792Sgshapiro New ruleset srv_features to enable/disable certain features in the 228590792Sgshapiro server per connection. See doc/op/op.me for details. 228690792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 228790792Sgshapiro recipient; useful to decide whether a conection is secure 228890792Sgshapiro enough on a per recipient basis. 228990792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 229090792Sgshapiro for STARTTLS. 229190792Sgshapiro If no certificate has been requested, the macro {verify} has the 229290792Sgshapiro value "NOT". 229390792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 229490792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 229590792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 229690792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 229790792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 229890792Sgshapiro really required. This change results in a noticable 229990792Sgshapiro performance gains on most machines. Moreover, if shared 230090792Sgshapiro memory is in use, reuse the key several times. 230190792Sgshapiro Add queue groups which can be used to group queue directories with 230290792Sgshapiro the same behavior together. See doc/op/op.me for details. 230390792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 230490792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 230590792Sgshapiro are initially sorted which may result in faster envelope 230690792Sgshapiro splitting. If the mail is submitted directly from the 230790792Sgshapiro command line, then the value also limits the number of 230890792Sgshapiro processes to deliver the envelopes; if more envelopes are 230990792Sgshapiro created they are only queued up and must be taken care of 231090792Sgshapiro by a queue run. 231190792Sgshapiro The check for 'enough disk space' now pays attention to which file 231290792Sgshapiro system each queue directory resides in. 231390792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 231490792Sgshapiro New option QueueFileMode for the default permissions of queue files. 231590792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 231690792Sgshapiro group (one or more queues in a multi-queue environment 231790792Sgshapiro collected together) to process the same work list at the 231890792Sgshapiro same time. 231990792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 232090792Sgshapiro active queue runner processes. 232190792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 232290792Sgshapiro runners per queue group. 232390792Sgshapiro Queue member selection by substring pattern matching now allows 232490792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 232590792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 232690792Sgshapiro of the queue that match during processing. 232790792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 232890792Sgshapiro periodically forking a child to process the queue, a single 232990792Sgshapiro child is forked for each queue that sleeps between queue 233090792Sgshapiro runs. A SIGHUP signal can be sent to restart this 233190792Sgshapiro persistent queue runner. 233290792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 233390792Sgshapiro sendmail process which only runs the queue at an interval: 233490792Sgshapiro sendmail -q15m). 233590792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 233690792Sgshapiro Proposed by Thom O'Connor. 233790792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 233890792Sgshapiro unless the new -qf option or -v is used. 233990792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 234090792Sgshapiro several queue runners are started by hand to avoid contention. 234190792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 234290792Sgshapiro of the qf file (older entries first). 234390792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 234490792Sgshapiro a client to specify an amount of time within which an e-mail 234590792Sgshapiro should be delivered. New option DeliverByMin added to set the 234690792Sgshapiro minimum amount of time or disable the extension. 234790792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 234890792Sgshapiro not allowed unless escaped or quoted. 234990792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 235090792Sgshapiro by Leif Johansson of Stockholm University, which was based on 235190792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 235290792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 235390792Sgshapiro Technology, Stockholm, Sweden. 235490792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 235590792Sgshapiro behavior (no MX lookups), put the name in square brackets. 235690792Sgshapiro Proposed by Thom O'Connor. 235790792Sgshapiro Use shared memory to store free space of filesystems that are used 235890792Sgshapiro for queues, if shared memory is available and if a key is set 235990792Sgshapiro via SharedMemoryKey. This minimizes the number of system 236090792Sgshapiro calls to check the available space. See doc/op/op.me for 236190792Sgshapiro details. 236290792Sgshapiro If shared memory is compiled in the option -bP can be used to print 236390792Sgshapiro the number of entries in the queue(s). 236490792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 236590792Sgshapiro and the usual documentation for details. 236690792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 236790792Sgshapiro Remove '-U' (initial user submission) command line option as 236890792Sgshapiro announced in 8.10. 236990792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 237090792Sgshapiro New macro {addr_type} which contains whether the current address is 237190792Sgshapiro an envelope sender or recipient address. Suggested by 237290792Sgshapiro Neil Rickert of Northern Illinois University. 237390792Sgshapiro Two new options for host maps: -d (retransmission timeout), 237490792Sgshapiro -r (number of retries). 237590792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 237690792Sgshapiro separator such that a lookup can return both an attribute 237790792Sgshapiro and value separated by the given separator. 237890792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 237990792Sgshapiro to map class arith. 238090792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 238190792Sgshapiro (errors that occur when sending an error message) are dropped. 238290792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 238390792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 238490792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 238590792Sgshapiro requirements for files containing secret keys. This is 238690792Sgshapiro necessary for the MSP if client authentification is used. 238790792Sgshapiro Properly handle quoted filenames for class files (to allow for 238890792Sgshapiro filenames with spaces). 238990792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 239090792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 239190792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 239290792Sgshapiro {if_addr_out} address of interface of outgoing connection. 239390792Sgshapiro {if_family_out} family of interface of outgoing connection. 239490792Sgshapiro The latter two are only set if the interface does not belong 239590792Sgshapiro to the loopback net. 239690792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 239790792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 239890792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 239990792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 240090792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 240190792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 240290792Sgshapiro all connections for a single delivery attempt to succeed. 240390792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 240490792Sgshapiro a threshold number of recipients has been rejected (option 240590792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 240690792Sgshapiro Development Group. 240790792Sgshapiro New option DelayLA to delay connections if the load averages 240890792Sgshapiro exceeds the specified value. The default of 0 does not 240990792Sgshapiro change the previous behavior. A value greater than 0 241090792Sgshapiro will cause sendmail to sleep for one second on most 241190792Sgshapiro SMTP commands and before accepting connections if that 241290792Sgshapiro load average is exceeded. 241390792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 241490792Sgshapiro recipients that are sent during a connection to a mailer. 241590792Sgshapiro This also introduces a new mailer field 'r' which defines 241690792Sgshapiro the maximum number of recipients (defaults to 100). 241790792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 241890792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 241990792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 242090792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 242190792Sgshapiro instead. 242290792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 242390792Sgshapiro builtin mailer pathnames. Use TCP instead. 242490792Sgshapiro PH map code updated to use the new libphclient API instead of the 242590792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 242690792Sgshapiro University of Illinois at Urbana-Champaign. 242790792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 242890792Sgshapiro for direct (command line) submissions. 242990792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 243090792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 243190792Sgshapiro Hagino of the KAME Project. 243290792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 243390792Sgshapiro whose content is rewritten similar to Reply-To:. 243490792Sgshapiro Proposed by Andrzej Filip. 243590792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 243690792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 243790792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 243890792Sgshapiro AUTH/STARTTLS related logfile entries. 243990792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 244090792Sgshapiro before logging. 244190792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 244290792Sgshapiro (at LogLevel 9/10 or higher). 244390792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 244490792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 244590792Sgshapiro in which most commands are rejected due to check_relay or 244690792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 244790792Sgshapiro Change logging format for cloned envelopes to be similar to that for 244890792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 244990792Sgshapiro of the Universitat Regensburg. 245090792Sgshapiro Added libsm, a C library of general purpose abstractions including 245190792Sgshapiro assertions, tracing and debugging with named debug categories, 245290792Sgshapiro exception handling, malloc debugging, resource pools, 245390792Sgshapiro portability abstractions, and an extensible buffered I/O 245490792Sgshapiro package. It will at some point replace libsmutil. 245590792Sgshapiro See libsm/index.html for details. 245690792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 245790792Sgshapiro care of by fork() and exit(). 245890792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 245990792Sgshapiro more consistent portablity amongst different platforms 246090792Sgshapiro new and old (from new libsm). 246190792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 246290792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 246390792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 246490792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 246590792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 246690792Sgshapiro synchronizations calls. 246790792Sgshapiro Add per-recipient status information to mailq -v output. 246890792Sgshapiro T_ANY queries are no longer used by sendmail. 246990792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 247090792Sgshapiro too (see include/sm/cdefs.h for more info). 247190792Sgshapiro sendmail -d now has general support for named debug categories. 247290792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 247390792Sgshapiro for details. 247490792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 247590792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 247690792Sgshapiro generated by this condition were illegal (not RFC conform). 247790792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 247890792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 247990792Sgshapiro mailer and the recipient has hence been rejected during the 248090792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 248190792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 248290792Sgshapiro that do not have postmaster defined. If an email was sent 248390792Sgshapiro from an address to which a DSN cannot be returned and 248490792Sgshapiro in which at least one recipient address is non-deliverable, 248590792Sgshapiro then that email had been delivered in each queue run. 248690792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 248790792Sgshapiro degli Studi dell'Insubria. 248890792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 248990792Sgshapiro i.e., the corresponding code is always compiled in now. 249090792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 249190792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 249290792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 249390792Sgshapiro attempting to canonify a hostname, some broken nameservers 249490792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 249590792Sgshapiro lookups. If you want to excuse this behavior, use this new 249690792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 249790792Sgshapiro Mark Roth of the University of Illinois at 249890792Sgshapiro Urbana-Champaign. 249990792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 250090792Sgshapiro noted by Joy Latten of IBM. 250190792Sgshapiro ConnectionRateThrottle limits the number of connections per second 250290792Sgshapiro to each daemon individually, not the overall number of 250390792Sgshapiro connections. 250490792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 250590792Sgshapiro sendmail to use a default alias schema as outlined in the 250690792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 250790792Sgshapiro cf/README. 250890792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 250990792Sgshapiro the first character after the class name is not a '/' or a 251090792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 251190792Sgshapiro rest of the line will be parsed as a map lookup. This 251290792Sgshapiro allows classes to be filled via a map lookup. See op.me 251390792Sgshapiro for more syntax information. Specifically, this can be 251490792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 251590792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 251690792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 251790792Sgshapiro example). 251890792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 251990792Sgshapiro the default schema used in the above two items. 252090792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 252190792Sgshapiro warning if a program being run from a mailer or file class 252290792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 252390792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 252490792Sgshapiro if a program being run from a mailer or file class 252590792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 252690792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 252790792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 252890792Sgshapiro (without quotes) will disable this and return to the 252990792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 253090792Sgshapiro Suggested by Bryan Stansell of GNAC. 253190792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 253290792Sgshapiro HELO/EHLO commands. 253390792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 253490792Sgshapiro possible protocol family which may be used for outgoing 253590792Sgshapiro connections. Restrictions placed on one family only affect 253690792Sgshapiro outgoing connections on that particular family. Because of 253790792Sgshapiro this change, the ${client_flags} macro is not set until the 253890792Sgshapiro connection is established. Based on patch from Motonori 253990792Sgshapiro Nakamura of Kyoto University. 254090792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 254190792Sgshapiro when the -bv option is given by users who are neither root 254290792Sgshapiro nor the TrustedUser so users can not read private aliases, 254390792Sgshapiro forwards, or :include: files. It also will override the -v 254490792Sgshapiro (verbose) command line option. 254590792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 254690792Sgshapiro address can't be used for the outgoing connection, fall 254790792Sgshapiro back to the settings in ClientPortOptions (if set). 254890792Sgshapiro Problem noted by John Beck of Sun Microsystems. 254990792Sgshapiro New named config file rule check_data for DATA command (input: 255090792Sgshapiro number of recipients). Based on patch from Mark Roth of 255190792Sgshapiro the University of Illinois at Urbana-Champaign. 255290792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 255390792Sgshapiro can be specified using the '#' option character. For 255490792Sgshapiro example, 'ETRN #queuegroup'. 255590792Sgshapiro If an LDAP server times out or becomes unavailable, close the 255690792Sgshapiro current connection and reopen to get to one of the fallback 255790792Sgshapiro servers. Patch from Paul Hilchey of the University of 255890792Sgshapiro British Columbia. 255990792Sgshapiro Make default error number on $#error messages 550 instead of 501 256090792Sgshapiro because 501 is not allowed on all commands. 256190792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 256290792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 256390792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 256490792Sgshapiro if required. 256590792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 256690792Sgshapiro class instead. 256790792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 256890792Sgshapiro "IPv6:" tag to identify the address properly. For example, 256990792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 257090792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 257190792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 257290792Sgshapiro MTA is running. For example, during a queue run. 257390792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 257490792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 257590792Sgshapiro Nelson of IBM. 257690792Sgshapiro The maximum number of commands before the MTA slows down when too 257790792Sgshapiro many "light weight" commands have been received are now 257890792Sgshapiro configurable during compile time. The current values and 257990792Sgshapiro their defaults are: 258090792Sgshapiro MAXBADCOMMANDS 25 unknown commands 258190792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 258290792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 258390792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 258490792Sgshapiro MAXETRNCOMMANDS 8 ETRN 258590792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 258690792Sgshapiro Costales of SL3D, Inc. 258790792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 258890792Sgshapiro ${MyMacro} is defined but also that it is not empty. 258990792Sgshapiro Properly quote usernames with special characters if they are used 259090792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 259190792Sgshapiro Meteorological Institute. 259290792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 259390792Sgshapiro messages for messages for mailing list expanded addresses 259490792Sgshapiro which are not delivered on the initial attempt. 259590792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 259690792Sgshapiro the final dot has been sent to avoid affecting future 259790792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 259890792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 259990792Sgshapiro file systems that require to call fsync() for a directory 260090792Sgshapiro if the meta-data in it has been changed. This should be 260190792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 260290792Sgshapiro See sendmail/README for further information. 260390792Sgshapiro Avoid file locking deadlock when updating the statistics file if 260490792Sgshapiro sendmail is signaled to terminate. Problem noted by 260590792Sgshapiro Christophe Wolfhugel of France Telecom. 260690792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 260790792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 260890792Sgshapiro the Finnish Meteorological Institute. 260990792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 261090792Sgshapiro from Peter A. Friend of EarthLink. 261190792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 261290792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 261390792Sgshapiro flora.ca. 261490792Sgshapiro Portability: 261590792Sgshapiro Remove support for AIX 2, which supports only 14 character 261690792Sgshapiro filenames and is outdated anyway. Suggested by 261790792Sgshapiro Valdis Kletnieks of Virginia Tech. 261890792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 261990792Sgshapiro i.e., use default /usr/sbin, change owner/group 262090792Sgshapiro of man pages and user-executable to root/sys, set 262190792Sgshapiro optimization limit to 0 (unlimited). Based on patch 262290792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 262390792Sgshapiro Hurtta of the Finnish Meteorological Institute. 262490792Sgshapiro Do not assume LDAP support is installed by default under 262590792Sgshapiro Solaris 8 and later. 262690792Sgshapiro Add support for OpenUNIX. 262790792Sgshapiro CONFIG: Increment version number of config file to 10. 262890792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 262990792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 263090792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 263190792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 263290792Sgshapiro temporary lookup failures. 263390792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 263490792Sgshapiro action to be taken by aborting the search for domain names 263590792Sgshapiro or IP nets. 263690792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 263790792Sgshapiro relay address as long as the other part allows the email 263890792Sgshapiro to get through. 263990792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 264090792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 264190792Sgshapiro entry like user+*@domain. This allows handling of details by 264290792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 264390792Sgshapiro introduced to match only non-empty details of addresses. 264490792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 264590792Sgshapiro and hence there is no required order within the MAILER 264690792Sgshapiro section anymore except for MAILER(`uucp') which must come 264790792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 264890792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 264990792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 265090792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 265190792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 265290792Sgshapiro in the access map which returns OK or RELAY actually 265390792Sgshapiro terminates check_* ruleset checking. 265490792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 265590792Sgshapiro tls_rcpt, see cf/README for details. 265690792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 265790792Sgshapiro STARTTLS has been used to "(version=${tls_version} 265890792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 265990792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 266090792Sgshapiro options friends/haters instead of "To:" and enable 266190792Sgshapiro specification of whole domains instead of just users. 266290792Sgshapiro Notice: this change is not backward compatible. 266390792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 266490792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 266590792Sgshapiro cf/README for details. 266690792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 266790792Sgshapiro the access map. Proposed by Randall Winchester of the 266890792Sgshapiro University of Maryland. 266990792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 267090792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 267190792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 267290792Sgshapiro messages for an unauthorized relaying attempt/for access 267390792Sgshapiro map entries with RHS REJECT, respectively. 267490792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 267590792Sgshapiro to specify another domain to be added instead of the local one. 267690792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 267790792Sgshapiro Solving. 267890792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 267990792Sgshapiro options, see doc/op/op.me for details. 268090792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 268190792Sgshapiro the security layer in SMTP AUTH (SASL). 268290792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 268390792Sgshapiro immediately. 268490792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 268590792Sgshapiro allows checking of the return values of the DNS lookups. 268690792Sgshapiro See cf/README for details. 268790792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 268890792Sgshapiro temporary lookup failures. 268990792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 269090792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 269190792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 269290792Sgshapiro memory use. 269390792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 269490792Sgshapiro of the sender and the recipient address delimited by the 269590792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 269690792Sgshapiro in the access map. Based on code contributed by Mathias 269790792Sgshapiro Koerber of Singapore Telecommunications Ltd. 269890792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 269990792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 270090792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 270190792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 270290792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 270390792Sgshapiro the recipient host if LUSER_RELAY is used. 270490792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 270590792Sgshapiro +detail portion of the address when passing address to 270690792Sgshapiro local delivery agent. Disables alias and .forward +detail 270790792Sgshapiro stripping. Only use if LDA supports this. 270890792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 270990792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 271090792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 271190792Sgshapiro Routing lookups.

If sendmail needs to drop 335864562Sgshapiro these privileges and the operating system doesn't set the 335964562Sgshapiro saved-uid as well, exit with an error. Problem noted by 336064562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 336164562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 336264562Sgshapiro it populates. It is possible that some broken 336364562Sgshapiro implementations of snprintf() exist that do not do this. 336464562Sgshapiro Systems in this category should compile with 336564562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 336664562Sgshapiro system and report broken implementations to 336764562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 336864562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 336964562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 337064562Sgshapiro Implementation influenced by the example programs of 337164562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 337264562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 337364562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 337464562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 337564562Sgshapiro cf/README and doc/op/op.*. 337664562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 337764562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 337864562Sgshapiro ${server_name}, and ${server_addr}. These are documented 337964562Sgshapiro in cf/README and doc/op/op.*. 338064562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 338164562Sgshapiro random data. 338264562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 338364562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 338464562Sgshapiro try to use STARTTLS despite the security problems. 338564562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 338664562Sgshapiro support encryption. Based on code contributed by Tim 338764562Sgshapiro Martin of CMU. 338864562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 338964562Sgshapiro strength factor. 339064562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 339164562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 339264562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 339364562Sgshapiro of CMU. 339464562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 339564562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 339664562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 339764562Sgshapiro Fix the default family selection for DaemonPortOptions. As 339864562Sgshapiro documented, unless a family is specified in a 339964562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 340064562Sgshapiro also the default if no DaemonPortOptions value is set. 340164562Sgshapiro Therefore, IPv6 users should configure additional sockets 340264562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 340364562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 340464562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 340564562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 340664562Sgshapiro the interface information for an outgoing connection. 340764562Sgshapiro Not doing so was creating a mismatch between the socket 340864562Sgshapiro family and address used in subsequent connections if the 340964562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 341064562Sgshapiro by John Beck of Sun Microsystems. 341164562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 341264562Sgshapiro family based on the IP address. ${if_family} is no longer 341364562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 341464562Sgshapiro of Sun Microsystems. 341564562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 341664562Sgshapiro macros for both the incoming interface address/family and 341764562Sgshapiro the outgoing interface address/family. In order for M=b 341864562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 341964562Sgshapiro the incoming information in the queue file for later 342064562Sgshapiro delivery attempts. 342164562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 342264562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 342364562Sgshapiro smoe.org. 342464562Sgshapiro Add more vigilance in checking for putc() errors on output streams 342564562Sgshapiro to protect from a bug in Solaris 2.6's putc().

Problem noted by Ari Heikkinen of Pohjois-Savo 344764562Sgshapiro Polytechnic. 344864562Sgshapiro Under the proper circumstances, failed connections would be recorded 344964562Sgshapiro as "Bad file number" instead of "Connection failed" in the 345064562Sgshapiro queue file and persistent host status. Problem noted by 345164562Sgshapiro Graeme Hewson of Oracle. 345264562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 345364562Sgshapiro within the hoststatus directory (e.g., lost+found). 345464562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 345564562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 345664562Sgshapiro sender.

This option and 373464562Sgshapiro its use is deprecated and will be removed from a future 373564562Sgshapiro version of sendmail. 373664562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 373764562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 373864562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 373964562Sgshapiro (IdS). 374064562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 374164562Sgshapiro a large number of files. See cf/README for more details. 374264562Sgshapiro The directory structure of the distribution has changed slightly 374364562Sgshapiro for easier code sharing among the programs. 374464562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 374564562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 374664562Sgshapiro which hold the client's authentication credentials, 374764562Sgshapiro the mechanism used for authentication, and the 374864562Sgshapiro authorization identity (i.e., the AUTH= parameter if 374964562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 375064562Sgshapiro On systems which use the Torek stdio library (all of the BSD 375164562Sgshapiro distributions), use memory-buffered files to reduce 375264562Sgshapiro file system overhead by not creating temporary files on 375364562Sgshapiro disk. Contributed by Exactis.com, Inc. 375464562Sgshapiro New option DataFileBufferSize to control the maximum size of a 375564562Sgshapiro memory-buffered data (df) file before a disk-based file is 375664562Sgshapiro used. Contributed by Exactis.com, Inc. 375764562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 375864562Sgshapiro memory-buffered transcript (xf) file before a disk-based 375964562Sgshapiro file is used. Contributed by Exactis.com, Inc. 376064562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 376164562Sgshapiro now listen on several different ports. Use: 376264562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 376364562Sgshapiro to run a Message Submission Agent (MSA); this is turned 376464562Sgshapiro on by default in m4-generated .cf files; it can be turned 376564562Sgshapiro off with FEATURE(`no_default_msa'). 376664562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 376764562Sgshapiro begin using RFC 2476 Message Submission for initial user 376864562Sgshapiro message submission. XUSR may disappear from a future release. 376964562Sgshapiro The new '-G' (relay (gateway) submission) command line option 377064562Sgshapiro indicates that the message being submitted from the command 377164562Sgshapiro line is for relaying, not initial submission. This means 377264562Sgshapiro the message will be rejected if the addresses are not fully 377364562Sgshapiro qualified and no canonicalization will be done. Future 377464562Sgshapiro releases may even reject improperly formed messages. 377564562Sgshapiro The '-U' (initial user submission) command line option is 377664562Sgshapiro deprecated and may be removed from a future release. 377764562Sgshapiro Mail user agents should begin using '-G' to indicate that 377864562Sgshapiro this is a relay submission (the inverse of -U). 377964562Sgshapiro The next release of sendmail will assume that any message submitted 378064562Sgshapiro from the command line is an initial user submission and act 378164562Sgshapiro accordingly. 378264562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 378364562Sgshapiro program or deliver to file as the owner of that file, the 378464562Sgshapiro address is marked as unsafe. This means if RunAsUser is 378564562Sgshapiro set, users won't be able to use programs or delivery to 378664562Sgshapiro files in their .forward files. Administrators can override 378764562Sgshapiro this by setting the DontBlameSendmail option to the new 378864562Sgshapiro setting NonRootSafeAddr. 378964562Sgshapiro Allow group or world writable directories if the sticky bit is set 379064562Sgshapiro on the directory and DontBlameSendmail is set to 379164562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 379264562Sgshapiro InCert Software. 379364562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 379464562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 379564562Sgshapiro set in the DontBlameSendmail option. Requested by many. 379664562Sgshapiro New Timeout.control option to limit the total time spent satisfying 379764562Sgshapiro a control socket request. 379864562Sgshapiro New Timeout.resolver options for controlling BIND resolver 379964562Sgshapiro settings: 380064562Sgshapiro Timeout.resolver.retrans 380164562Sgshapiro Sets the resolver's retransmission time interval (in 380264562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 380364562Sgshapiro and Timeout.resolver.retrans.normal. 380464562Sgshapiro Timeout.resolver.retrans.first 380564562Sgshapiro Sets the resolver's retransmission time interval (in 380664562Sgshapiro seconds) for the first attempt to deliver a message. 380764562Sgshapiro Timeout.resolver.retrans.normal 380864562Sgshapiro Sets the resolver's retransmission time interval (in 380964562Sgshapiro seconds) for all resolver lookups except the first 381064562Sgshapiro delivery attempt. 381164562Sgshapiro Timeout.resolver.retry 381264562Sgshapiro Sets the number of times to retransmit a resolver 381364562Sgshapiro query. Sets both Timeout.resolver.retry.first 381464562Sgshapiro and Timeout.resolver.retry.normal. 381564562Sgshapiro Timeout.resolver.retry.first 381664562Sgshapiro Sets the number of times to retransmit a resolver 381764562Sgshapiro query for the first attempt to deliver a message. 381864562Sgshapiro Timeout.resolver.retry.normal 381964562Sgshapiro Sets the number of times to retransmit a resolver 382064562Sgshapiro query for all resolver lookups except the first 382164562Sgshapiro delivery attempt. 382264562Sgshapiro Contributed by Exactis.com, Inc. 382364562Sgshapiro Support multiple queue directories. To use multiple queues, supply 382464562Sgshapiro a QueueDirectory option value ending with an asterisk. For 382564562Sgshapiro example, /var/spool/mqueue/q* will use all of the 382664562Sgshapiro directories or symbolic links to directories beginning with 382764562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 382864562Sgshapiro mind, the queue directory structure should not be changed 382964562Sgshapiro while sendmail is running. Queue runs create a separate 383064562Sgshapiro process for running each queue unless the verbose flag is 383164562Sgshapiro given on a non-daemon queue run. New items are randomly 383264562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 383364562Sgshapiro Support different directories for qf, df, and xf queue files; if 383464562Sgshapiro subdirectories or symbolic links to directories of those names 383564562Sgshapiro exist in the queue directories, they are used for the 383664562Sgshapiro corresponding queue files. Keep in mind, the queue 383764562Sgshapiro directory structure should not be changed while sendmail is 383864562Sgshapiro running. Proposed by Mathias Koerber of Singapore 383964562Sgshapiro Telecommunications Ltd. 384064562Sgshapiro New queue file naming system which uses a filename guaranteed to be 384164562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 384264562Sgshapiro without fancy file system locking. Queued items can be 384364562Sgshapiro moved between queues easily. Contributed by Exactis.com, 384464562Sgshapiro Inc. 384564562Sgshapiro Messages which are undeliverable due to temporary address failures 384664562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 384764562Sgshapiro set. Contributed by Exactis.com, Inc. 384864562Sgshapiro New command line option '-L tag' which sets the identifier used for 384964562Sgshapiro syslog. Contributed by Exactis.com, Inc. 385064562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 385164562Sgshapiro avoids opening and reading each queue file when preparing 385264562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 385364562Sgshapiro Shared memory counters and microtimers functionality has been 385464562Sgshapiro donated by Exactis.com, Inc. 385564562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 385664562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 385764562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 385864562Sgshapiro being added. Suggested by Michael K. Sanders. 385964562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 386064562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 386164562Sgshapiro and John Beck of Sun Microsystems. 386264562Sgshapiro In low-disk space situations, where sendmail would previously refuse 386364562Sgshapiro connections, still accept them, but only allow ETRN commands. 386464562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 386564562Sgshapiro Ltd. 386664562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 386764562Sgshapiro on systems which support them. This can be used with LMTP 386864562Sgshapiro local delivery agents which listen on a named socket. An 386964562Sgshapiro example mailer might be: 387064562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 387164562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 387264562Sgshapiro A=FILE /var/run/lmtpd 387364562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 387464562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 387564562Sgshapiro instead. 387664562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 387764562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 387864562Sgshapiro connections), IPC (which will be deprecated in a future 387964562Sgshapiro version), and FILE (for UNIX domain socket delivery). 388064562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 388164562Sgshapiro flags. 388264562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 388364562Sgshapiro body of the original message on delivery status 388464562Sgshapiro notifications. 388564562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 388664562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 388764562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 388864562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 388964562Sgshapiro Steve Schweinhart of America Online. 389064562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 389164562Sgshapiro not be set after rulesets are defined. Suggested by 389264562Sgshapiro Mitchell Blank Jr of Exec-PC. 389364562Sgshapiro Do not report temporary failure on delivery to files. In 389464562Sgshapiro interactive delivery mode, this would result in two SMTP 389564562Sgshapiro responses after the DATA command.

Fix from Raj Kunjithapadam of 390364562Sgshapiro @Home Network. 390464562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 390564562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 390664562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 390764562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 390864562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 390964562Sgshapiro similar to check_rcpt etc. 391064562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 391164562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 391264562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 391364562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 391464562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 391564562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 391664562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 391764562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 391864562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 391964562Sgshapiro the corresponding DSN parameter values. Proposed by 392064562Sgshapiro Mathias Herberts. 392164562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 392264562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 392364562Sgshapiro before the message has been collected, thereafter it holds 392464562Sgshapiro the message size as computed by sendmail (and can be used 392564562Sgshapiro in check_compat). 392664562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 392764562Sgshapiro sendmail is using instead of the value of the DeliveryMode 392864562Sgshapiro option. 392964562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 393064562Sgshapiro Drop explicit From: if same as what would be generated only if it is 393164562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 393264562Sgshapiro Write pid to file also if sendmail only processes the queue. 393364562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 393464562Sgshapiro Log "low on disk space" only when necessary. 393564562Sgshapiro New macro ${load_avg} can be used to check the current load average. 393664562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 393764562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 393864562Sgshapiro is set. 393964562Sgshapiro Flag -S for maps to specify the character which is substituted 394064562Sgshapiro for spaces (instead of the default given by O BlankSub). 394164562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 394264562Sgshapiro This flag is set by default for the host map. Based on a 394364562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 394464562Sgshapiro Open maps only on demand, not at startup. 394564562Sgshapiro Log warning about unsupported IP address families. 394664562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 394764562Sgshapiro of the sum of all headers. This can be used to prevent 394864562Sgshapiro a denial-of-service attack. 394964562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 395064562Sgshapiro headers and parameters within those headers. This option 395164562Sgshapiro is intended to protect mail user agents from buffer 395264562Sgshapiro overflow attacks. 395364562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 395464562Sgshapiro alias recursion. 395564562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 395664562Sgshapiro Map type syslog to log the key via syslogd. 395764562Sgshapiro Entries in the alias file can be continued by putting a backslash 395864562Sgshapiro directly before the newline. 395964562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 396064562Sgshapiro dead.letter file, formerly hardcoded to 396164562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 396264562Sgshapiro default), sendmail will not attempt to save to a 396364562Sgshapiro system-wide dead.letter file if it can not bounce the mail 396464562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 396564562Sgshapiro file as it has in the past when the dead.letter file 396664562Sgshapiro could not be opened. 396764562Sgshapiro New option PidFile to define the location of the pid file. The 396864562Sgshapiro value of this option is macro expanded. 396964562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 397064562Sgshapiro process title shown in 'ps' listings. 397164562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 397264562Sgshapiro (along with the already existing macros): 397364562Sgshapiro ${daemon_info} Daemon information, e.g. 397464562Sgshapiro SMTP+queueing@00:30:00 397564562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 397664562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 397764562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 397864562Sgshapiro ${daemon_port} Daemon port, e.g., 25 397964562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 398064562Sgshapiro New macros especially for virtual hosting: 398164562Sgshapiro ${if_name} hostname of interface of incoming connection. 398264562Sgshapiro ${if_addr} address of interface of incoming connection. 398364562Sgshapiro The latter is only set if the interface does not belong to the 398464562Sgshapiro loopback net. 398564562Sgshapiro If a message being accepted via a method other than SMTP and 398664562Sgshapiro would be rejected by a header check, do not send the message. 398764562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 398864562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 398964562Sgshapiro Provide header value as quoted string in the macro 399064562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 399164562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 399264562Sgshapiro The length of the header value is stored in ${hdrlen}. 399364562Sgshapiro H*: allows to specify a default ruleset for header checks. This 399464562Sgshapiro ruleset will only be called if the individual header does 399564562Sgshapiro not have its own ruleset assigned. Suggested by Jan 399664562Sgshapiro Krueger of Unix-AG of University of Hannover. 399764562Sgshapiro The name of the header field stored in ${hdr_name}. 399864562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 399964562Sgshapiro removed if the config file version is greater than or equal 400064562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 400164562Sgshapiro input "token (1)" but does not match "token". 400264562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 400364562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 400464562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 400564562Sgshapiro Ericsson. 400664562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 400764562Sgshapiro messages with 8-bit text in headers. Problem noted by 400864562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 400964562Sgshapiro of Ericsson. 401064562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 401164562Sgshapiro modified database map file. Problem noted by Chris Adams 401264562Sgshapiro of Renaissance Internet Services. 401364562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 401464562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 401564562Sgshapiro queue up the message instead of bouncing it. 401664562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 401764562Sgshapiro standard does not provide any indication of what to do when 401864562Sgshapiro something other than 250 is received. Based on a patch 401964562Sgshapiro from Steve Schweinhart of America Online. 402064562Sgshapiro New option TrustedUser allows to specify a user who can own 402164562Sgshapiro important files instead of root. This requires HASFCHOWN. 402264562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 402364562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 402464562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 402564562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 402664562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 402764562Sgshapiro $? tests also whether the macro is non-null. 402864562Sgshapiro Print an error message if a mailer definition contains an invalid 402964562Sgshapiro equate name. 403064562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 403164562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 403264562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 403364562Sgshapiro mailer to return after sending all data to it. 403464562Sgshapiro Only free memory from the process list when adding a new process 403564562Sgshapiro into a previously filled slot. Previously, the memory was 403664562Sgshapiro freed at removal time. Since removal can happen in a 403764562Sgshapiro signal handler, this may leave the memory map in an 403864562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 403964562Sgshapiro David Cooley of Colby College. 404064562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 404164562Sgshapiro local users in the passwd file. The UserDB code has 404264562Sgshapiro already decided the message will be passed to another host 404364562Sgshapiro for processing. Fix from Tony Landells of Burdett 404464562Sgshapiro Buckeridge Young Limited. 404564562Sgshapiro Support LDAP authorization via either a file containing the 404664562Sgshapiro password or Kerberos V4 using the new map options 404764562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 404864562Sgshapiro distinguished_name is who to login as. The method can be 404964562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 405064562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 405164562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 405264562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 405364562Sgshapiro of Stanford University. 405464562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 405564562Sgshapiro deprecated and will be removed in a future version. 405664562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 405764562Sgshapiro and the map has the column delimiter set, it turns that 405864562Sgshapiro response into a delimiter separated string. The LDAP map 405964562Sgshapiro will traverse multiple entries as well. LDAP alias maps 406064562Sgshapiro automatically set the column delimiter to the comma. 406164562Sgshapiro Based on patch from Booker Bense of Stanford University and 406264562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 406364562Sgshapiro Support return of multiple values for a single LDAP lookup. The 406464562Sgshapiro values to be returned should be in a comma separated string. 406564562Sgshapiro For example, `-v "email,emailother"'. Patch from 406664562Sgshapiro Curtis W. Hillegas of Princeton University. 406764562Sgshapiro Allow the use of LDAP for alias maps. 406864562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 406964562Sgshapiro attributes found in the match will be returned. 407064562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 407164562Sgshapiro breaking up a single entry into multiple entries. This is 407264562Sgshapiro needed for LDAP alias file specifications to allow for 407364562Sgshapiro comma separated key and value strings. 407464562Sgshapiro Keep connections to LDAP server open instead of opening and closing 407564562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 407664562Sgshapiro connections such that multiple maps which use the same 407764562Sgshapiro host, port, bind DN, and authentication will only result in 407864562Sgshapiro a single connection to that host. 407964562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 408064562Sgshapiro Be more careful about checking for errors and freeing memory on 408164562Sgshapiro LDAP lookups. 408264562Sgshapiro Use asynchronous LDAP searches to save memory and network 408364562Sgshapiro resources. 408464562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 408564562Sgshapiro Increase portability to the Netscape LDAP libraries. 408664562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 408764562Sgshapiro replaced with the literal contents of the map lookup key -- 408864562Sgshapiro note that this means a lookup can be done using the LDAP 408964562Sgshapiro special characters. The new '%0' token can be used instead 409064562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 409164562Sgshapiro For example, if the LDAP map specification contains '-k 409264562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 409364562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 409464562Sgshapiro user attribute. Instead, if the LDAP map specification 409564562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 409664562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 409764562Sgshapiro with the name "*". 409864562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 409964562Sgshapiro more than one is returned, it is equivalent to no records 410064562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 410164562Sgshapiro alias dereference option; "-Z size" limits the number of 410264562Sgshapiro matches to return. 410364562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 410464562Sgshapiro LDAP maps. The value should only contain LDAP specific 410564562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 410664562Sgshapiro settings will be used for all LDAP maps unless they are 410764562Sgshapiro specified in the individual map specification ('K' 410864562Sgshapiro command). This option should be set before any LDAP maps 410964562Sgshapiro are defined. 411064562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 411164562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 411264562Sgshapiro Tech. 411364562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 411464562Sgshapiro particular, class entries get much smaller, which can be 411564562Sgshapiro important if you have large classes. 411664562Sgshapiro On network-related temporary failures, record the hostname which 411764562Sgshapiro gave error in the queued status message. Requested by 411864562Sgshapiro Ulrich Windl of the Universitat Regensburg. 411964562Sgshapiro Add new F=% mailer flag to allow for a store and forward 412064562Sgshapiro configuration. Mailers which have this flag will not attempt 412171345Sgshapiro delivery on initial receipt of a message or on queue runs 412264562Sgshapiro unless the queued message is selected using one of the 412364562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 412464562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 412564562Sgshapiro New option ControlSocketName which, when set, creates a daemon 412664562Sgshapiro control socket. This socket allows an external program to 412764562Sgshapiro control and query status from the running sendmail daemon 412864562Sgshapiro via a named socket, similar to the ctlinnd interface to the 412964562Sgshapiro INN news server. Access to this interface is controlled by 413064562Sgshapiro the UNIX file permissions on the named socket on most UNIX 413164562Sgshapiro systems (see sendmail/README for more information). An 413264562Sgshapiro example control program is provided as contrib/smcontrol.pl. 413364562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 413464562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 413564562Sgshapiro number of processors online on the system (if that can be 413664562Sgshapiro determined). For single processor machines, this change 413764562Sgshapiro has no effect. 413864562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 413964562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 414064562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 414164562Sgshapiro Motonori Nakamura of Kyoto University. 414264562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 414364562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 414464562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 414564562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 414664562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 414764562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 414864562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 414964562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 415064562Sgshapiro connection-based denial of service attacks. 415164562Sgshapiro Log basic information about authenticated connections at LogLevel 415264562Sgshapiro 10 or higher. 415364562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 415464562Sgshapiro information (from= syslog line). 415564562Sgshapiro Log the DSN code for each recipient if one is available as a new 415664562Sgshapiro equate (dsn=). 415764562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 4158120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 4159120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 4160120256Sgshapiro of the University of Illinois at Urbana-Champaign. 416164562Sgshapiro Detect temporary lookup failures in the host map if looking up a 416264562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 416364562Sgshapiro Finnish Meteorological Institute. 416464562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 416564562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 416664562Sgshapiro When a forward file points to an alias which runs a program, run 416764562Sgshapiro the program as the default user and the default group, not 416864562Sgshapiro the forward file user. This change also assures the 416964562Sgshapiro :include: directives in aliases are also processed using 417064562Sgshapiro the default user and group. Problem noted by Sergiu 417164562Sgshapiro Popovici of DNT Romania. 417264562Sgshapiro Prevent attempts to save a dead.letter file for a user with 417364562Sgshapiro no home directory (/no/such/directory). Problem noted by 417464562Sgshapiro Michael Brown of Finnigan FT/MS. 417564562Sgshapiro Include message delay and number of tries when logging that a 417664562Sgshapiro message has been completely delivered (LogLevel of 10 or 417764562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 417864562Sgshapiro Log the sender of a message even if none of the recipients were 417964562Sgshapiro accepted. If some of the recipients were rejected, it is 418064562Sgshapiro helpful to know the sender of the message. 418164562Sgshapiro Check the root directory (/) when checking a path for safety. 418264562Sgshapiro Problem noted by John Beck of Sun Microsystems. 418364562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 418464562Sgshapiro interactive and delivering to an alias which resolves to 418564562Sgshapiro multiple files. 418664562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 418764562Sgshapiro greater (see below); the help function doesn't print the 418864562Sgshapiro version of sendmail any longer, instead it is placed in 418964562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 419064562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 419164562Sgshapiro skipped and a version line (#vers) is introduced. The 419264562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 419364562Sgshapiro version is found, a warning is logged. The '#vers' 419464562Sgshapiro directive should be placed at the top of the help file. 419564562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 419664562Sgshapiro disk succeeded. Suggested by Nick Christenson. 419764562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 419864562Sgshapiro length before the attempt. 419964562Sgshapiro If a forward points to a filename for delivery, change to the 420064562Sgshapiro user's uid before checking permissions on the file. This 420164562Sgshapiro allows delivery to files on NFS mounted directories where 420264562Sgshapiro root is remapped to nobody. Problem noted by Harald 420364562Sgshapiro Daeubler of Universitaet Ulm. 420464562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 420564562Sgshapiro host status files, not all files. 420664562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 420764562Sgshapiro in the queue file for the message and set when delivery 420864562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 420964562Sgshapiro Wonderworks Inc. 421064562Sgshapiro Add support for storing information between rulesets using the new 421164562Sgshapiro macro map class. This can be used to store information 421264562Sgshapiro between queue runs as well using $={persistentMacros}. 421364562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 421464562Sgshapiro of Hannover. 421564562Sgshapiro New map class arith to allow for computations in rules. The 421664562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 421764562Sgshapiro as key. The two operands are specified as arguments; the 421864562Sgshapiro lookup returns the result of the computation. For example, 421964562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 422064562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 422164562Sgshapiro Add new syntax for header declarations which decide whether to 422264562Sgshapiro include the header based on a macro rather than a mailer 422364562Sgshapiro flag: 422464562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 422564562Sgshapiro This should be used along with $={persistentMacros}. 422664562Sgshapiro It can be used for adding headers to a message based on 422764562Sgshapiro the results of check_* and header check rulesets. 422864562Sgshapiro Allow new named config file rule check_eoh which is called after 422964562Sgshapiro all of the headers have been collected. The input to the 423064562Sgshapiro ruleset the number of headers and the size of all of the 423164562Sgshapiro headers in bytes separated by $|. This ruleset along with 423264562Sgshapiro the macro storage map can be used to correlate information 423364562Sgshapiro gathered between headers and to check for missing headers. 423464562Sgshapiro See cf/README or doc/op/op.ps for an example. 423564562Sgshapiro Change the default for the MeToo option to True to correspond 423664562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 423764562Sgshapiro option is deprecated and will be removed from a future 423864562Sgshapiro version. 423964562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 424064562Sgshapiro Change the sendmail binary default for SuperSafe to True. 424164562Sgshapiro Display ruleset names in debug and address test mode output 424264562Sgshapiro if referencing a named ruleset. 424364562Sgshapiro New mailer equate m= which will limit the number of messages 424464562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 424564562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 424664562Sgshapiro using it to sort. Now all the same domains are really run 424764562Sgshapiro through the queue together. If they have the same MX host, 424864562Sgshapiro then they will have a much better opportunity to use the 424964562Sgshapiro connection cache if available. This should be a reasonable 425064562Sgshapiro performance improvement. Patch from Randall Winchester of 425164562Sgshapiro the University of Maryland. 425264562Sgshapiro If a message is rejected by a header check ruleset, log who would 425364562Sgshapiro have received the message if it had not been rejected. 425464562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 425564562Sgshapiro queue immediately.

Problem noted by Per 443064562Sgshapiro Hedeland of Ericsson. 443164562Sgshapiro mailq displays unprintable characters in addresses as their octal 443264562Sgshapiro representation and a leading backslash. This avoids problems 443364562Sgshapiro with "unprintable" characters. Problem noted by Michal 443464562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 443564562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 443664562Sgshapiro one character past the limit. This would cause subsequent 443764562Sgshapiro hops to break the line again. The '!' is now placed in 443864562Sgshapiro the last column of the limit if the line needs to be broken. 443964562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 444064562Sgshapiro from Per Hedeland of Ericsson. 444164562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 444264562Sgshapiro resolver will fall back to TCP. However, some 444364562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 444464562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 444564562Sgshapiro don't fail on ANY queries. 444664562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 444764562Sgshapiro address, do not send an empty postmaster notification DSN 444864562Sgshapiro to the postmaster.

Prindeville of Enteka Enterprise Technology 467364562Sgshapiro Services. 467464562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 467564562Sgshapiro names. Problem noted by Randall Winchester of Swales 467664562Sgshapiro Aerospace. 467764562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 467864562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 467964562Sgshapiro University and Brian Candler. 468064562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 468164562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 468264562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 468364562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 468464562Sgshapiro Institute. 468564562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 468664562Sgshapiro i.e., to set, add, or delete flags. 468764562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 468864562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 468964562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 469064562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 469164562Sgshapiro after check_rcpt and allows for exceptions from the checks. 469264562Sgshapiro CONFIG: Map declarations have been moved into their associated 469364562Sgshapiro feature files to allow greater flexibility in use of 469464562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 469564562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 469664562Sgshapiro line string for the local mailer. Requested by Il Oh of 469764562Sgshapiro Willamette Industries, Inc. 469864562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 469964562Sgshapiro converted to <user@d> 470064562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 470164562Sgshapiro Sun's older, broken configuration files. 470264562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 470364562Sgshapiro normal configuration, allowing anti-spam checks to be 470464562Sgshapiro performed. 470564562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 470664562Sgshapiro ${client_name} can't be resolved just temporarily. 470764562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 470864562Sgshapiro Institute. 470964562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 471064562Sgshapiro be accessed by their numbers). 471164562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 471264562Sgshapiro which describes whether to disallow "!" in the local part 471364562Sgshapiro of an address. 471464562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 471564562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 471664562Sgshapiro set. If the ruleset returns a mailer, the appropriate 471764562Sgshapiro action is taken, otherwise the returned tokens are ignored. 471864562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 471964562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 472064562Sgshapiro The latter is kept around for backward compatibility. 472164562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 472264562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 472364562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 472464562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 472564562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 472664562Sgshapiro Institute. 472764562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 472864562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 472964562Sgshapiro arguments overriding the mailer program, arguments, and 473064562Sgshapiro mailer definition flags. This makes it possible to use 473164562Sgshapiro other programs such as maildrop for local delivery. 473264562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 473364562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 473464562Sgshapiro Patch from Richard A.

Problem noted by Ezequiel H. Panepucci of 475064562Sgshapiro Yale University. 475164562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 475264562Sgshapiro be used for building. 475364562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 475464562Sgshapiro used for a fresh build. 475564562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 475664562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 475764562Sgshapiro ranlib. 475864562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 475964562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 476064562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 476164562Sgshapiro building of the man pages when defined. Suggested by Bryan 476264562Sgshapiro Costales. 476364562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 476464562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 476564562Sgshapiro installation of the sendmail helpfile and statistics file 476664562Sgshapiro respectively. Suggested by Bryan Costales. 476764562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 476864562Sgshapiro of Siemens Business Services. 476964562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 477064562Sgshapiro stdio library. The new buffered file I/O depends on the 477164562Sgshapiro Torek stdio library. This option can be either portable or 477264562Sgshapiro torek. 477364562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 477464562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 477564562Sgshapiro They should contain the C source files for the object files 477664562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 477764562Sgshapiro will be passed to the 'make depend' stage of compilation. 477864562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 477964562Sgshapiro in the sendmail distribution. Each has the form 478064562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 478164562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 478264562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 478364562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 478464562Sgshapiro building the distribution, but documentation on the changes 478564562Sgshapiro are in devtools/README. 478664562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 478764562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 478864562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 478964562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 479064562Sgshapiro new variable which identifies the root of the source 479164562Sgshapiro directories for all of the programs in the distribution. 479264562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 479364562Sgshapiro time. They can both still be overridden by setting the m4 479464562Sgshapiro macro. 479564562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 479664562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 479764562Sgshapiro build configurations, and places objects in obj.prefix.*/. 479864562Sgshapiro Complains as 'Build -f file' does for existing object 479964562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 480064562Sgshapiro Corporation. 480164562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 480264562Sgshapiro manual pages in the directory tree specified by 480364562Sgshapiro confMANROOTMAN. 480464562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 480564562Sgshapiro preformatted pages from the distribution. The new variable 480664562Sgshapiro confCOPY specifies the copying program. 480764562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 480864562Sgshapiro question. Suggested by Terry Lambert of Whistle 480964562Sgshapiro Communications. 481064562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 481164562Sgshapiro of the installed statistics and help files, respectively. 481264562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 481364562Sgshapiro operating system identity. Problem noted by Erik 481464562Sgshapiro Wachtenheim of Dartmouth College. 481564562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 481664562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 481764562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 481864562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 481964562Sgshapiro how to strip binaries. These are used by the new 482064562Sgshapiro install-strip target. 482164562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 482264562Sgshapiro the others (if it exists). 482364562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 482464562Sgshapiro then the default ones. 482590792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 482664562Sgshapiro as local delivery agent without LMTP mode, use 482764562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 482864562Sgshapiro to set the S flag. 482964562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 483064562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 483164562Sgshapiro Northern Illinois University. 483264562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 483364562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 483464562Sgshapiro the Finnish Meteorological Institute. 483564562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 483664562Sgshapiro MAILLOCK when compiling. Also requires linking with 483764562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 483864562Sgshapiro University. 483964562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 484064562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 484164562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 484264562Sgshapiro University. 484364562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 484464562Sgshapiro structure to the beginning of the program. This ensures that 484564562Sgshapiro the getservbyname() is done before any seteuid to a possibly 484664562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 484764562Sgshapiro on a Solaris system, this avoids syslog messages such as, 484864562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 484964562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 485064562Sgshapiro University. 485164562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 485264562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 485364562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 485464562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 485564562Sgshapiro characters (in LMTP mode), mail.local split the incoming 485664562Sgshapiro line up into 2046-character output lines (excluding the 485764562Sgshapiro newline).

Sites 535538032Speter which need the ability to override security can use the 535638032Speter DontBlameSendmail option. See the README file for more 535738032Speter information. 535838032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 535938032Speter if maps or alias files are in world writable directories. 536038032Speter This fixes the change added to 8.8.6 to prevent links in these 536138032Speter world writable directories. 536238032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 536338032Speter it is in a world writable directory. 536438032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 536538032Speter tty it may be able to push bytes back to the senders input. 536638032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 537538032Speter reverts back to the old behavior of using uid 1 and gid 1. 537638032Speter This is a security problem for Linux which has chosen that 537738032Speter uid and gid for user bin instead of daemon. If DefaultUser 537838032Speter is set in the configuration file, that value overrides this 537938032Speter default. 538090792Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-ID binaries 538138032Speter interfered with setting an alternate group id for the 538238032Speter RunAsUser option.

After this number is reached, sendmail 542638032Speter starts returning "452 Too many recipients" to all RCPT 542738032Speter commands. This can be used to limit the number of recipients 542838032Speter per envelope (in particular, to discourage use of the server 542938032Speter for spamming). Note: a better approach is to restrict 543038032Speter relaying entirely. 543138032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 543238032Speter to ldapx map and added timeout for ldap_open call to 543338032Speter avoid hanging sendmail in the event of hung LDAP servers. 543438032Speter Patch from Booker Bense of Stanford University. 543538032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 545438032Speter of Procter & Gamble. 545538032Speter The LDAP map -s flag was not properly parsed and the error message 545664562Sgshapiro given included the remainder of the arguments instead of 545738032Speter solely the argument in error. Problem noted by Aidan Nichol 545838032Speter of Procter & Gamble. 545938032Speter New DontBlameSendmail option. This option allows administrators to 546038032Speter bypass some of sendmail's file security checks at the expense 546138032Speter of system security.

In particular, if you 549738032Speter have lots of virtual interfaces, this option will speed up 549838032Speter startup.

If they differ or if the PTR lookup 550838032Speter fails, &{client_name} will contain the IP address 550964562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 551038032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 551138032Speter (i.e, it is like -ax for the temporary failure case, in 551238032Speter contrast to the success case). 551338032Speter New syntax to do limited checking of header syntax. A config line 551438032Speter of the form: 551538032Speter HHeader: $>Ruleset 551638032Speter causes the indicated Ruleset to be invoked on the Header 551738032Speter when read. This ruleset works like the check_* rulesets -- 551838032Speter that is, it can reject mail on the basis of the contents. 551938032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 552038032Speter from hiding their connection information in Received: 552138032Speter headers. 552238032Speter When SingleThreadDelivery is active, deliveries to locked hosts 552338032Speter are skipped. This will cause the delivering process to 552438032Speter try the next MX host or queue the message if no other MX 552538032Speter hosts are available. Suggested by Alexander Litvin. 552638032Speter The [FILE] mailer type now delivers to the file specified in the 552738032Speter A= equate of the mailer definition instead of $u. It also 552838032Speter obeys all of the F= mailer flags such as the MIME 552938032Speter 7/8 bit conversion flags. This is useful for defining 553038032Speter a mailer which delivers to the same file regardless of the 553164562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 553238032Speter Do not assume the identity of a remote connection is root@localhost 553338032Speter if the remote connection closes the socket before the 553438032Speter remote identity can be queried. 553538032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 553638032Speter Some mailers, including procmail, require that the real 553738032Speter uid is left unchanged by sendmail. Problem noted by Per 553838032Speter Hedeland of Ericsson. 553938032Speter No longer is the src/obj*/Makefile selected from a large list -- it 554038032Speter is now generated using the information in BuildTools/OS/ -- 554138032Speter some of the details are determined dynamically via 554238032Speter BuildTools/bin/configure.sh. 554338032Speter The other programs in the sendmail distribution -- mail.local, 554438032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 554538032Speter the new Build method which creates an operating system 554638032Speter specific Makefile using the information in BuildTools. 554738032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 554838032Speter a failure on one message won't affect future messages to the 554938032Speter same host). This is necessary if the remote host sends 555038032Speter a 451 error if the domain of the sender does not resolve 555138032Speter as is common in anti-spam configurations. Problem noted 555238032Speter by Mitchell Blank Jr of Exec-PC. 555338032Speter New "discard" mailer for check_* rulesets and header checking 555438032Speter rulesets. If one of the above rulesets resolves to the 555538032Speter $#discard mailer, the commands will be accepted but the 555638032Speter message will be completely discarded after it is accepting. 555738032Speter This means that even if only one of the recipients 555838032Speter resolves to the $#discard mailer, none of the recipients 555938032Speter will receive the mail. Suggested by Brian Kantor. 556038032Speter All but the last cloned envelope of a split envelope were queued 556138032Speter instead of being delivered.

This database gives you the ability to allow 569538032Speter or refuse to accept mail from specified domains for 569638032Speter administrative reasons. By default, names that are listed 569738032Speter as "OK" in the access db are domain names, not host names. 569838032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 569938032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 570038032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 570138032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 570238032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 570338032Speter of FEATURE(access_db) and class 'R' to lookup individual 570438032Speter host names only. 570538032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 570638032Speter using % addressing is used, e.g. user%site@othersite, 570738032Speter and othersite is in class 'R', the check_rcpt ruleset 570838032Speter will strip @othersite and recheck user@site for relaying. 570938032Speter This feature changes that behavior. It should not be 571038032Speter needed for most installations. 571138032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 571238032Speter domain portion of the mail sender is a local host. This 571338032Speter should only be used if absolutely necessary as it opens 571438032Speter a window for spammers. Patch from Randall S.

Problem noted by Kari Hurtta of the Finnish 587538032Speter Meteorological Institute. 587638032Speter If /usr/tmp/dead.letter already existed, sendmail could not 587738032Speter add additional bounces to it. Problem noted by Thomas J. 587838032Speter Arseneault of SRI International. 587938032Speter If an SMTP mailer used a non-standard port number for the outgoing 588038032Speter connection, it would be displayed incorrectly in verbose mode. 588138032Speter Problem noted by John Kennedy of Cal State University, Chico. 588238032Speter Log the ETRN parameter specified by the client before altering them 588338032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 588438032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 588538032Speter User unknown with bogus delay= values. Change them to log 588638032Speter the same as compliant addresses. Problem noted by Kari E. 588738032Speter Hurtta of the Finnish Meteorological Institute. 588838032Speter Ignore the debug resolver option unless using sendmail debug trace 588938032Speter option for resolver. Problem noted by Greg Nichols of Wind 589038032Speter River Systems. 589138032Speter If SingleThreadDelivery was enabled and the remote server returned a 589238032Speter protocol error on the DATA command, the connection would be 589338032Speter closed but the persistent host status file would not be 589438032Speter unlocked so other sendmail processes could not deliver to 589538032Speter that host. Problem noted by Peter Wemm of DIALix. 589638032Speter If queueing up a message due to an expensive mailer, don't increment 589738032Speter the number of delivery attempts or set the last delivery 589838032Speter attempt time so the message will be delivered on the next 589938032Speter queue run regardless of MinQueueAge. Problem noted by 590038032Speter Brian J. Coan of the Institute for Global Communications. 590138032Speter Authentication warnings of "Processed from queue _directory_" and 590238032Speter "Processed by _username_ with -C _filename_" would be logged 590338032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 590438032Speter of the Finnish Meteorological Institute. 590538032Speter Use a better heuristic for detecting GDBM. 590638032Speter Log null connections on dropped connections. Problem noted by 590738032Speter Jon Lewis of Florida Digital Turnpike. 590838032Speter If class dbm maps are rebuilt, sendmail will now detect this and 590938032Speter reopen the map. Previously, they could give stale 591038032Speter results during a single message processing (but would 591138032Speter recover when the next message was received). Fix from 591238032Speter Joe Pruett of Q7 Enterprises. 591338032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 591438032Speter requests. Problem noted by Kari E. Hurtta of the 591538032Speter Finnish Meteorological Institute. 591638032Speter Do not send a bounce message back to the sender regarding bad 591738032Speter recipients if the SMTP connection is dropped before the 591838032Speter message is accepted. Problem noted by Kari E. Hurtta of the 591938032Speter Finnish Meteorological Institute. 592038032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 592138032Speter sendmail via a UNIX pipe. This will allow rulesets using 592238032Speter $&{client_name} to process without sending the string through 592338032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 592438032Speter A combination of deferred delivery mode, a double bounce situation, 592538032Speter and the inability to save a bounce message to 592638032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 592738032Speter to postmaster but not remove the offending envelope from the 592838032Speter queue causing it to create a new bounce message each time the 592938032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 593038032Speter Associates. 593138032Speter Remove newlines from hostname information returned via DNS. There are 593238032Speter no known security implications of newlines in hostnames as 593338032Speter sendmail filters newlines in all vital areas; however, this 593438032Speter could cause confusing error messages. 593538032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 593638032Speter rejected if any of the specified addresses were bad. This 593738032Speter behavior was modified to only reject the bad addresses and not 593838032Speter the entire message. Problem noted by Jozsef Hollosi of 593938032Speter SuperNet, Inc. 594038032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 594138032Speter Bryan Costales of InfoBeat, Inc. 594238032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 594338032Speter mailers. Problem noted by Kari E. Hurtta of the 594438032Speter Finnish Meteorological Institute. 594538032Speter An error in calculating the available space in the list of addresses 594638032Speter for logging deliveries could cause an address to be silently 594738032Speter dropped. 594838032Speter Include the initial user environment if sendmail is restarted via 594938032Speter a HUP signal. This will give room for the process title. 595038032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 595138032Speter Mail could be delivered without a body if the machine does not 595238032Speter support flock locking and runs out of processes during 595338032Speter delivery. Fix from Chuck Lever of the University of Michigan. 595438032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 595538032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 595638032Speter Institute. 595738032Speter Make sure non-rebuildable database maps are opened before the 595864562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 595938032Speter are needed for verifying the left hand side of the aliases. 596038032Speter Problem noted by Lloyd Parkes of Victoria University. 596138032Speter Make sure sender RFC822 source route addresses are alias expanded for 596238032Speter bounce messages. Problem noted by Juergen Georgi of 596338032Speter RUS University of Stuttgart. 596438032Speter Minor lint fixes. 596538032Speter Return a temporary error instead of a permanent error if an LDAP map 596638032Speter search returns an error. This will allow sequenced maps which 596738032Speter use other LDAP servers to be checked. Fix from Booker Bense 596838032Speter of Stanford University. 596938032Speter When automatically converting from quoted printable to 8bit text do 597038032Speter not pad bare linefeeds with a space. Problem noted by Theo 597138032Speter Nolte of the University of Technology Aachen, Germany. 597238032Speter Portability: 597338032Speter Non-standard C compilers may have had a problem compiling 597438032Speter conf.c due to a standard C external declaration of 597538032Speter setproctitle(). Problem noted by Ted Roberts of 597638032Speter Electronic Data Systems. 597738032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 597838032Speter Jagielski of jaguNET Access Services. 597938032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 598038032Speter Digital UNIX: Digital UNIX (and possibly others) moves 598138032Speter loader environment variables into the loader memory 598238032Speter area. If one of these environment variables (such as 598338032Speter LD_LIBRARY_PATH) was the last environment variable, 598438032Speter an invalid memory address would be used by the process 598538032Speter title routine causing memory corruption. Problem 598638032Speter noted by Sam Hartman of Mesa Internet Systems. 598738032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 598838032Speter chownsafe() to always return 0 even if the OS does 598938032Speter not permit file giveaways. Problem noted by 599038032Speter Yasutaka Sumi of The University of Tokyo. 599164562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 599238032Speter Gerald Rinske of Siemens Business Services VAS. 599338032Speter Linux: Pad process title with NULLs. Problem noted by 599438032Speter Jon Lewis of Florida Digital Turnpike. 599538032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 599638032Speter incorrect value for the number of interfaces. 599738032Speter Problem noted by Chris Loelke of JetStream Internet 599838032Speter Services. 599938032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 600038032Speter Rinske of Siemens Business Services VAS. 600138032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 600238032Speter used on a Solaris machine. Problem noted by 600338032Speter Stephen Ma of Jtec Pty Limited. 600438032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 600538032Speter Services VAS. 600638032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 600738032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 600838032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 600938032Speter Ericsson. 601038032Speter 601164562Sgshapiro8.8.7/8.8.7 1997/08/03 601238032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 601338032Speter an exclusive lock already set -- i.e., almost all systems 601438032Speter except 4.4-BSD derived systems), the initial attempt at 601538032Speter rebuilding aliases file if the database didn't already 601638032Speter exist would fail. Patch from Raymund Will of LST Software 601738032Speter GmbH. 601838032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 601938032Speter Problem noted by Fredrik J�nsson of the Royal Institute 602038032Speter of Technology, Stockholm. 602138032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 602238032Speter some environments could give "multiple definitions" for these 602338032Speter routines during compilation. If using TCP Wrappers, assume 602438032Speter that these routines are included as though they were in the 602538032Speter C library. Patch from Robert La Ferla. 602638032Speter When a NEWDB database map was rebuilt at the same time it was being 602738032Speter used by a queue run, the maps could be left locked for the 602838032Speter duration of the queue run, causing other processes to hang. 602938032Speter Problem noted by Kendall Libby of Shore.NET. 603038032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 603138032Speter mail was passed on without any recipient header. This could 603238032Speter cause problems downstream. Problem noted by Xander Jansen 603338032Speter of SURFnet ExpertiseCentrum. 603438032Speter Give error when GDBM is used with sendmail. GDBM's locking and 603538032Speter linking of the .dir and .pag files interferes with sendmail's 603638032Speter locking and security checks. Problems noted by Fyodor 603738032Speter Yarochkin of the Kyrgyz Republic FreeNet. 603838032Speter Don't fsync qf files if SuperSafe option is not set. 603938032Speter Avoid extra calls to gethostbyname for addresses for which a 604038032Speter gethostbyaddr found no value. Also, ignore any returns 604138032Speter from gethostbyaddr that look like a dotted quad. 604238032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 604338032Speter "may be forged", since at the network level we pretty much 604438032Speter have to assume that the information is good. 604538032Speter In some cases, errors during an SMTP session could leave files 604638032Speter open or locked. 604738032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 604890792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 604938032Speter errors during testing. 605038032Speter Errors in file locking of NEWDB maps had the incorrect file name 605138032Speter printed in the error message. 605238032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 605338032Speter missing parameter were issued, the EHLO behaved like a HELO. 605438032Speter Load limiting never kicked in for incoming SMTP transactions if the 605543730Speter DeliveryMode=background and any recipient was an alias or 605638032Speter had a .forward file. From Nik Conwell of Boston University. 605738032Speter On some non-Posix systems, the decision of whether chown(2) permits 605838032Speter file giveaway was undefined. From Tetsu Ushijima of the 605938032Speter Tokyo Institute of Technology. 606038032Speter Fix race condition that could cause the body of a message to be 606138032Speter lost (so only the header was delivered). This only occurs 606238032Speter on systems that do not use flock(2), and only when a queue 606338032Speter runner runs during a critical section in another message 606438032Speter delivery. Based on a patch from Steve Schweinhart of 606538032Speter Results Computing. 606638032Speter If a qf file was found in a mail queue directory that had a problem 606738032Speter (wrong ownership, bad format, etc.) and the file name was 606838032Speter exactly MAXQFNAME bytes long, then instead of being tried 606938032Speter once, it would be tried on every queue run. Problem noted 607038032Speter by Bryan Costales of Mercury Mail. 607138032Speter If the system supports an st_gen field in the status structure, 607238032Speter include it when reporting that a file has changed after open. 607338032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 607438032Speter This out to be checked as well as reported, since it is 607538032Speter theoretically possible for an attacker to remove a file after 607638032Speter it is opened and replace it with another file that has the 607738032Speter same i-number, but some filesystems (notably AFS) return 607838032Speter garbage in this field, and hence always look like the file 607938032Speter has changed. As a practical matter this is not a security 608038032Speter problem, since the files can be neither hard nor soft links, 608138032Speter and on no filesystem (that I am aware of) is it possible to 608238032Speter have two files on the same filesystem with the same i-number 608338032Speter simultaneously. 608438032Speter Delete the root Makefile from the distribution -- it is only for 608538032Speter use internally, and does not work at customer sites. 608638032Speter Fix botch that caused the second MAIL FROM: command in a single 608738032Speter transaction to clear the entire transaction. Problem 608838032Speter noted by John Kennedy of Cal State University, Chico. 608938032Speter Work properly on machines that have _PATH_VARTMP defined without 609038032Speter a trailing slash. (And a pox on vendors that decide to 609138032Speter ignore the established conventions!) Problem noted by 609238032Speter Gregory Neil Shapiro of WPI. 609338032Speter Internal changes to make it easier to add another protocol family 609438032Speter (intended for IPv6). Patches are from John Kennedy of 609538032Speter CSU Chico. 609638032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 609738032Speter an extra space at the beginning of some lines. Problem 609838032Speter noted by Charles Karney of Princeton University; fix based 609938032Speter on a patch from Christophe Wolfhugel. 610038032Speter Portability: 610138032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 610238032Speter with the _Sendmail_ book, 2nd edition. Note that 610338032Speter the book is actually wrong: _PATH_SENDMAILCF should 610438032Speter be used instead. 610538032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 610638032Speter of Argonne National Laboratory. 610738032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 610838032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 610938032Speter SunOS: Include <memory.h> to fix warning from util.c. From 611038032Speter James Aldridge of EUnet Ltd. 611138032Speter Solaris: Change STDIR (location of status file) to /etc/mail 611238032Speter in Makefiles. 611338032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 611438032Speter Makefiles. Use NEWDB on Linux instead. 611538032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 611638032Speter exists but behaves differently than other OSes. 611738032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 611838032Speter around the problem. Problem noted by Tom Moore of 611938032Speter NCR Corp. 612038032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 612138032Speter noted by Tom Smith of Digital Equipment Corp. 612238032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 612338032Speter noted by Tom Good of the Community Access Information 612438032Speter Resource Network 612538032Speter SCO 4.2: compile problems caused by a change in the type of 612638032Speter the "length" parameters passed to accept, getpeername, 612738032Speter getsockname, and getsockopt. Adds new compile flags 612838032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. Problem reported 612938032Speter by Tom Good of St. Vincent's North Richmond Community 613038032Speter Mental Health Center Residential Services. 613138032Speter AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. 613238032Speter Suggested by Brett Hogden of Rochester Gas & Electric 613338032Speter Corp. 613438032Speter Linux: avoid compile problem for versions of <setjmp.h> that 613538032Speter #define both setjmp and longjmp.

This makes it possible to create a root 617338032Speter owned file in an arbitrary directory by inserting the symlink 617438032Speter into a writable directory after the initial lstat(2) check 617538032Speter determined that the file did not exist. The only verified 617638032Speter example of a system having these odd semantics for O_EXCL 617738032Speter and symbolic links was HP-UX prior to version 9.07. Most 617838032Speter systems do not have the problem, since a exclusive create 617938032Speter of a file disallows symbolic links. Systems that have been 618038032Speter verified to NOT have the problem include AIX 3.x, *BSD, 618138032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 618238032Speter and Ultrix. This is a potential exposure on systems that 618338032Speter have this bug and which do not have a MAILER-DAEMON alias 618438032Speter pointing at a legitimate account, since this will cause old 618538032Speter mail to be dropped in /var/tmp/dead.letter. 618638032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 618738032Speter if maps or alias files are in world writable directories. 618838032Speter If your system has alias maps in writable directories, it 618938032Speter is potentially possible for an attacker to replace the .db 619038032Speter (or .dir and .pag) files by symbolic links pointing at 619138032Speter another database; this can be used either to expose 619238032Speter information (e.g., by pointing an alias file at /etc/spwd.db 619338032Speter and probing for accounts), or as a denial-of-service attack 619438032Speter (by trashing the password database). The fix disallows 619538032Speter symbolic links entirely when rebuilding alias files or on 619638032Speter maps that are in writable directories, and always warns on 619738032Speter writable directories; 8.9 will probably consider writable 619838032Speter directories to be fatal errors. This does not represent an 619938032Speter exposure on systems that have alias files in unwritable 620038032Speter system directories. 620138032Speter SECURITY: disallow .forward or :include: files that are links (hard 620238032Speter or soft) if the parent directory (or any directory in the 620338032Speter path) is writable by anyone other than the owner. This is 620438032Speter similar to the previous case for user files. This change 620538032Speter should not affect most systems, but is necessary to prevent 620638032Speter an attacker who can write the directory from pointing such 620738032Speter files at other files that are readable only by the owner. 620838032Speter SECURITY: Tighten safechown rules: many systems will say that they 620938032Speter have a safe (restricted to root) chown even on files that 621038032Speter are mounted from another system that allows owners to give 621138032Speter away files. The new rules are very strict, trusting file 621238032Speter ownership only in those few cases where the system has 621338032Speter been verified to be at least as paranoid as necessary. 621438032Speter However, it is possible to relax the rules to partially 621538032Speter trust the ownership if the directory path is not world or 621638032Speter group writable. This might allow someone who has a legitimate 621738032Speter :include: file (referenced directly from /etc/aliases) to 621838032Speter become another non-root user if the :include: file is in a 621938032Speter non-writable directory on an NFS-mounted filesystem where 622038032Speter the local system says that giveaway is denied but it is 622138032Speter actually permitted. I believe this to be a very small set 622238032Speter of cases. If in doubt, do not point :include: aliases at 622338032Speter NFS-mounted filesystems. 622438032Speter SECURITY: When setting a numeric group id using the RunAsUser option 622538032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 622638032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 622738032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 622838032Speter The user id was still set properly. Problem noted by Uli 622938032Speter Pralle of the Technical University of Berlin. 623038032Speter Save the initial gid set for use when checking for if the 623138032Speter PrivacyOptions=restrictmailq option is set. Problem reported 623238032Speter by Wolfgang Ley of DFN-CERT. 623338032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 623438032Speter failure on one message won't affect future messages to the 623538032Speter same host). 623638032Speter IP source route printing had an "off by one" error that would 623738032Speter affect any options that came after the route option. Patch 623838032Speter from Theo de Raadt. 623938032Speter The "Message is too large" error didn't successfully bounce the error 624038032Speter back to the sender. Problem reported by Stephen More of 624138032Speter PSI; patch from Gregory Neil Shapiro of WPI. 624238032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 624338032Speter of 5.1.3); it apparently gets used in multiple ways. 624438032Speter Suggested by John Myers of Portola Communications. 624538032Speter Fix possible extra null byte generated during collection if errors 624638032Speter occur at the beginning of the stream. Patch contributed by 624738032Speter Andrey A. Chernov and Gregory Neil Shapiro. 624838032Speter Code changes to avoid possible reentrant call of malloc/free within 624938032Speter a signal handler. Problem noted by John Beck of Sun 625038032Speter Microsystems. 625138032Speter Move map initialization to be earlier so that check_relay ruleset 625238032Speter will have the latest version of the map data. Problem noted 625338032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 625438032Speter If there are fatal errors during the collection phase (e.g., message 625538032Speter too large) don't send the bogus message. 625638032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 625738032Speter have errors and have owner- aliases. Problem noted by Michael 625838032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 625938032Speter Avoid null pointer dereference on illegal Boundary= parameters in 626038032Speter multipart/mixed Content-Type: header. Problem noted by 626138032Speter Richard Muirden of RMIT University. 626238032Speter Always print error messages during newaliases (-bi) even if the 626338032Speter ErrorMode is not set to "print". Fix from Gregory Neil 626438032Speter Shapiro. 626538032Speter Test mode could core dump if you did a /map lookup in an optional map 626638032Speter that could not be opened. Based on a fix from John Beck of 626738032Speter Sun Microsystems. 626838032Speter If DNS is misconfigured so that the last MX record tried points to 626938032Speter a host that does not have an A record, but other MX records 627038032Speter pointed to something reasonable, don't bounce the message 627138032Speter with a "host unknown" error. Note that this should really 627238032Speter be fixed in the zone file for the domain. Problem noted by 627338032Speter Joe Rhett of Navigist, Inc. 627438032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 627538032Speter the message as having been tried; otherwise the next queue 627638032Speter run will not realize that this is a second attempt and will 627738032Speter retry immediately. Problem noted by Bryan Costales of 627838032Speter Mercury Mail. 627938032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 628038032Speter will be run until the later setting of the clock is reached. 628138032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 628238032Speter Morgan Stanley. 628338032Speter If the load average rises above the cutoff threshold (above which 628438032Speter sendmail will not process the queue at all) during a queue 628538032Speter run, abort the queue run immediately. Problem noted by 628638032Speter Bryan Costales of Mercury Mail. 628738032Speter The variable queue processing algorithm (based on the message size, 628838032Speter number of recipients, message precedence, and job age) was 628938032Speter non-functional -- either the entire queue was processed or 629038032Speter none of the queue was processed. The updated algorithm 629138032Speter does no queue run if a single recipient zero size job will 629238032Speter not be run. 629338032Speter If there is a fatal ("panic") message that will cause sendmail to 629438032Speter die immediately, never hold the error message for future 629538032Speter printing. 629638032Speter Force ErrorMode=print in -bt mode so that all errors are printed 629738032Speter regardless of the setting of the ErrorMode option in the 629838032Speter configuration file. Patch from Gregory Neil Shapiro. 629938032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 630038032Speter routine available in one of the libraries. Use it in conf.h. 630138032Speter The -m (match only) flag now works on host class maps. 630238032Speter If class hash or btree maps are rebuilt, sendmail will now detect 630338032Speter this and reopen the map. Previously, they could give 630438032Speter erroneous results during a single message processing 630538032Speter (but would recover when the next message was received). 630638032Speter Don't delete zero length queue files when doing queue runs until the 630738032Speter files are at least ten minutes old. This avoids a potential 630838032Speter race condition: the creator creates the qf file, getting back 630938032Speter a file descriptor. The queue runner locks it and deletes it 631038032Speter because it is zero length. The creator then writes the 631138032Speter descriptor that is now for a disconnected file, and the 631238032Speter job goes away. Based on a suggestion by Bryan Costales. 631338032Speter When determining the "validated" host name ($_ macro), do a forward 631438032Speter (A) DNS lookup on the result of the PTR lookup and compare 631538032Speter results. If they differ or if the PTR lookup fails, tag the 631638032Speter address as "may be forged". 631738032Speter Log null connections (i.e., hosts that connect but do not do any 631838032Speter substantive activity on the connection before disconnecting; 631938032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 632038032Speter Always permit "writes" to /dev/null regardless of the link count. 632138032Speter This is safe because /dev/null is special cased, and no open 632238032Speter or write is ever actually attempted. Patch from Villy Kruse 632338032Speter of TwinCom. 632438032Speter If a message cannot be sent because of a 552 (exceeded storage 632538032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 632638032Speter was given, don't return the body in the bounce, since there 632738032Speter is a very good chance that the message will double-bounce. 632838032Speter Fix possible line truncation if a quoted-printable had an =00 escape 632938032Speter in the body. Problem noted by Charles Karney of the Princeton 633038032Speter Plasma Physics Laboratory. 633138032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 633238032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 633338032Speter Institute. 633438032Speter The MaxDaemonChildren option wasn't applying to queue runs as 633538032Speter documented. Note that this increases the potential denial 633638032Speter of service problems with this option: an attacker can 633738032Speter connect many times, and thereby lock out queue runs as well 633838032Speter as incoming connections. If you use this option, you should 633938032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 634038032Speter to avoid this attack. Failure to limit noted by Matthew 634138032Speter Dillon of BEST Internet Communications. 634238032Speter Always give a message in newaliases if alias files cannot be 634338032Speter opened instead of failing silently. Suggested by Gregory 634438032Speter Neil Shapiro. This change makes the code match the O'Reilly 634538032Speter book (2nd edition). 634638032Speter Some older versions of the resolver could return with h_errno == -1 634738032Speter if no name server could be reached, causing mail to bounce 634838032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 634938032Speter John Beck of SunSoft. 635038032Speter If a :include: file is owned by a user that does not have an entry 635138032Speter in the passwd file, sendmail could dereference a null pointer. 635238032Speter Problem noted by Satish Mynam of Sun Microsystems. 635338032Speter Take precautions to make sure that the SMTP protocol cannot get out 635438032Speter of sync if (for example) an alias file cannot be opened. 635538032Speter Fix a possible race condition that can cause a SIGALRM to come in 635638032Speter immediately after a SIGHUP, causing the new sendmail to die. 635738032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 635838032Speter from Villy Kruse of TwinCom. 635938032Speter Ignore improperly formatted SMTP reply codes. Previously these were 636038032Speter partially processed, which could cause confusing error 636138032Speter returns. 636238032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 636338032Speter on some architectures. 636438032Speter Portability: 636538032Speter A/UX: from Jim Jagielski of NASA/GSFC. 636638032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 636738032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 636838032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 636938032Speter defined. Problem reported by A Sun of the University 637038032Speter of Washington. 637138032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 637238032Speter the system rather than guessing at compile time. 637338032Speter Patch contributed by John Beck of Sun Microsystems. 637438032Speter Intel Paragon: from Wendy Lin of Purdue University. 637538032Speter GNU Hurd: from Miles Bader of the GNU project. 637638032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 637738032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 637838032Speter Unfortunately releasing them opens a race condition, 637938032Speter but there appears to be no fix for this. Patch from 638038032Speter Gregory Neil Shapiro. 638138032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 638238032Speter Solaris: a bug in strcasecmp caused characters with the 638338032Speter high order bit set to apparently randomly match 638438032Speter letters -- for example, $| (0233) matches "i" and "I". 638538032Speter Problem noted by John Gregson of the University of 638638032Speter Cambridge. 638738032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 638838032Speter Kari Hurtta. 638938032Speter IRIX 6.x: Create Makefiles for systems that claim to be 639038032Speter IRIX64 but are 6.2 or higher (so use the regular 639138032Speter IRIX Makefile). 639238032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 639338032Speter Problem noted by Eric Hagberg of Morgan Stanley. 639438032Speter CONFIG: Some canonification was still done for UUCP-like addresses 639538032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 639638032Speter Brian Candler. 639738032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 639838032Speter local names as local. Problem noted by Jeff Polk of BSDI; 639938032Speter fix provided by Gregory Neil Shapiro. 640038032Speter CONFIG: The "local:user" syntax entries in mailertables and other 640138032Speter "mailer:user" syntax locations returned an incorrect value 640238032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 640338032Speter CONFIG: Retain "+detail" information when forwarding mail to a 640438032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 640538032Speter Guenther of Gustavus Adolphus College. 640638032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 640738032Speter rules are the same as for aliasing. Based on a patch from 640838032Speter Gregory Neil Shapiro. 640938032Speter CONFIG: Break up parsing rules into several pieces; this should 641038032Speter have no functional change in this release, but makes it 641138032Speter possible to have better anti-spam rulesets in the future. 641238032Speter CONFIG: Disallow double dots in host names to avoid having the 641338032Speter HostStatusDirectory store status under the wrong name. 641438032Speter In some cases this can be used as a denial-of-service attack. 641538032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 641638032Speter Gregory Neil Shapiro. 641738032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 641838032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 641938032Speter don't include From_, and convert to 8-bit). Suggestions 642038032Speter from Kimmo Suominen and Roderick Schertler. 642164562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 642238032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 642338032Speter was specified, even when it wasn't. 642438032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 642538032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 642638032Speter "slip in" a symbolic link between the lstat(2) call and the 642738032Speter exclusive open. This is only a problem on System V derived 642838032Speter systems that allow an exclusive create on files that are 642938032Speter symbolic links pointing nowhere. 643038032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 643138032Speter not reset back to root, which on some systems would cause 643238032Speter later mailboxes to fail. Also, any partial message would 643338032Speter not be truncated, which could result in repeated deliveries. 643438032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 643538032Speter developers). 643638032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 643738032Speter change to the sendmail map code was made in 8.8.3. Problem 643838032Speter noted by Gregory Neil Shapiro. 643938032Speter MAKEMAP: Give warnings on file problems such as map files that are 644090792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 644138032Speter often run as root and hence has the potential for the same 644238032Speter sorts of problems as alias rebuilds. 644338032Speter MAKEMAP: Change compilation so that it will link properly on 644438032Speter NEXTSTEP. 644538032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 644638032Speter Accept an optional list of arguments following the server 644738032Speter name for the ETRN arguments to use (instead of $=w).

This 645138032Speter Perl script converts GECOS information in the /etc/passwd 645238032Speter file into aliases, allowing for faster access to full name 645338032Speter lookups; it is also clever about adding aliases (to root) 645438032Speter for system accounts. 645538032Speter NEW FILES: 645638032Speter src/safefile.c 645738032Speter cf/ostype/gnuhurd.m4 645838032Speter cf/ostype/irix6.m4 645938032Speter contrib/passwd-to-alias.pl 646038032Speter src/Makefiles/Makefile.IRIX64.6.1 646138032Speter src/Makefiles/Makefile.IRIX64.6.x 646238032Speter RENAMED FILES: 646338032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 646438032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 646538032Speter 646664562Sgshapiro8.8.5/8.8.5 1997/01/21 646738032Speter SECURITY: Clear out group list during startup. Without this, sendmail 646838032Speter will continue to run with the group permissions of the caller, 646938032Speter even if RunAsUser is specified. 647038032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 647138032Speter to any known attack, but it's best to be conservative. 647238032Speter Suggested by Peter Wemm of DIALix. 647338032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 647438032Speter security implications. Patch from Alex Garthwaite of the 647538032Speter University of Pennsylvania. 647638032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 647738032Speter would truncate the address after "Full". Although the -f 647838032Speter syntax is incorrect (since it is in the envelope, it 647938032Speter shouldn't have comments and full names), the failure mode 648038032Speter was unnecessarily awful. 648138032Speter Fix a possible null pointer dereference when converting 8-bit data 648238032Speter to a 7-bit format. Problem noted by Jim Hutchins of 648338032Speter Sandia National Labs and David James of British Telecom. 648438032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 648538032Speter runs. Although this really shouldn't be used (F=9 is for 648638032Speter final delivery only, and using it on an SMTP mailer makes 648738032Speter it possible for a message to be converted from 8->7->8->7 648838032Speter bits several times), it shouldn't have failed with a syserr. 648938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 649038032Speter _Really_ fix the multiple :maildrop code in the user database 649138032Speter module. Patch from Roy Mongiovi of Georgia Tech. 649238032Speter Let F lines in the configuration file actually read root-only 649338032Speter files if the configuration file is safe. Based on a 649438032Speter patch from Keith Reynolds of SCO. 649538032Speter ETRN followed by QUIT would hold the connection open until the queue 649638032Speter run completed. Problem noted by Truck Lewis of TDK 649738032Speter Semiconductor Corp. 649838032Speter It turns out that despite the documentation, the TCP wrappers library 649938032Speter does _not_ log rejected connections. Do the logging ourselves. 650038032Speter Problem noted by Fletcher Mattox of the University of Texas 650138032Speter at Austin. 650238032Speter If sendmail finds a qf file in its queue directory that is an unknown 650338032Speter version (e.g., when backing out to an old version), the 650438032Speter error is reported on every queue run. Change it to only 650538032Speter give the error once (and rename the qf => Qf). Patch from 650638032Speter William A. Gianopoulos of Raytheon Company. 650738032Speter Start a new session when doing background delivery; currently it 650838032Speter ignored signals but didn't start a new signal, that caused 650938032Speter some problems if a background process tried to send mail 651038032Speter under certain circumstances. Problem noted by Eric Hagberg 651138032Speter of Morgan Stanley; fix from Kari Hurtta. 651238032Speter Simplify test for skipping a queue run to just check if the current 651338032Speter load average is >= the queueing load average. Previously 651438032Speter the check factored in some other parameters that caused it 651538032Speter to essentially never skip the queue run. Patch from Bryan 651638032Speter Costales. 651738032Speter If the SMTP server is running in "nullserver" mode (that is, it is 651838032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 651938032Speter (25) commands; this helps prevent a bad guy from putting 652038032Speter you into a tight loop as a denial-of-service attack. Based 652138032Speter on an e-mail conversation with Brad Knowles of AOL. 652238032Speter Slow down when too many "light weight" commands have been issued; 652338032Speter this helps prevent a class of denial-of-service attacks. 652438032Speter The current values and defaults are: 652538032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 652638032Speter MAXHELOCOMMANDS 3 HELO, EHLO 652738032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 652838032Speter MAXETRNCOMMANDS 8 ETRN 652938032Speter These will probably be configurable in a future release. 653038032Speter On systems that have uid_t typedefed to be an unsigned short, programs 653138032Speter that had the F=S flag and no U= equate would be invoked with 653238032Speter the real uid set to 65535 rather than being left unchanged. 653338032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 653438032Speter by Steve Hubert of the University of Washington, Seattle. 653538032Speter Mail that was Quoted-Printable encoded and had a soft line break on 653638032Speter the last line (i.e., an incomplete continuation) had the last 653738032Speter line dropped. Since this appears to be illegal it isn't 653838032Speter clear what to do with it, but flushing the last line seems 653938032Speter to be a better "fail soft" approach. Based on a patch from 654038032Speter Eric Hagberg. 654138032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 654238032Speter bogus HELO command still causes the "Polite people say HELO 654338032Speter first" error message. Problem pointed out by Chris Thomas 654438032Speter of UCLA; patch from John Beck of SunSoft. 654538032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 654671345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 654771345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 654871345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 654938032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 655038032Speter in a DATA transaction to be sticky; these can occur because 655138032Speter a message is too large, and smaller messages should still go 655238032Speter through. Problem noted by Matt Dillon of Best Internet 655338032Speter Communications. 655438032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 655538032Speter had been successfully delivered to the envelope sender. 655638032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 655738032Speter Gregory Neil Shapiro of WPI. 655838032Speter Give better diagnostics on long alias lines. Based on code contributed 655938032Speter by Patrick Gosling of the University of Cambridge. 656038032Speter Increase the number of virtual interfaces that will be probed for 656138032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 656238032Speter PORTABILITY: 656338032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 656438032Speter Toshiaki Nomura of Fujitsu Limited. 656538032Speter SunOS with LDAP support: compile problems with struct timeval. 656638032Speter Patch from Nick Cuccia of TCSI Corporation. 656738032Speter SCO: from Keith Reynolds of SCO. 656838032Speter Solaris: kstat load average computation wasn't being used. 656938032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 657038032Speter (Moscow). 657138032Speter OpenBSD: from Jason Downs of teeny.org. 657238032Speter Altos System V: from Tim Rice. 657338032Speter Solaris 2.5: from Alan Perry of SunSoft. 657438032Speter Solaris 2.6: from John Beck of SunSoft. 657538032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 657638032Speter of Pratt & Whitney <miorelli@pweh.com>. 657738032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 657838032Speter _just_right_ yet. Tweak it again. I'll omit the names 657938032Speter of the "contributors" (quantity two) in this one case. 658038032Speter As of now, NO MORE DISCUSSION about the syntax of the 658138032Speter Received: line. 658238032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 658338032Speter it never inserts that class into the output file. Fix it 658438032Speter so it will honor EXPOSED_USER but will _not_ include root 658538032Speter automatically in this class. Problem noted by Ronan KERYELL 658638032Speter of Centre de Recherche en Informatique de l'�cole Nationale 658738032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 658838032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 658938032Speter such as LUSER_RELAY. This change permits the following 659038032Speter syntaxes: ``local:'' will send to the same user on the 659138032Speter local machine (e.g., in a mailertable entry for "host", 659238032Speter ``local:'' will cause an address addressed to user@host to 659338032Speter go to user on the local machone). ``local:user'' will send 659438032Speter to the named user on the local machine. ``local:user@host'' 659538032Speter is equivalent to ``local:user'' (the host is ignored). In 659638032Speter all cases, the original user@host is passed in $@ (i.e., the 659738032Speter detail information). Inspired by a report from Michael Fuhr. 659838032Speter CONFIG: Strip quotes from the first word of an "error:" host 659938032Speter indication. This lets you set (for example) the LUSER_RELAY 660038032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 660138032Speter of the \" so that the resulting string is properly quoted. 660238032Speter Problem noted by Gregory Neil Shapiro of WPI. 660338032Speter OP.ME: documentation was inconsistent about whether sendmail did a 660438032Speter NOOP or a RSET to probe the connection (it does a RSET). 660538032Speter Inconsistency noted by Deeran Peethamparam. 660638032Speter OP.ME: insert additional blank pages so it will print properly on 660738032Speter a duplex printer. From Matthew Black of Cal State University, 660838032Speter Long Beach. 660938032Speter 661064562Sgshapiro8.8.4/8.8.4 1996/12/02 661138032Speter SECURITY: under some circumstances, an attacker could get additional 661238032Speter permissions by hard linking to files that were group 661338032Speter writable by the attacker. The solution is to disallow any 661438032Speter files that have hard links -- this will affect .forward, 661538032Speter :include:, and output files. Problem noted by Terry 661638032Speter Kyriacopoulos of Interlog Internet Services. As a 661738032Speter workaround, set UnsafeGroupWrites -- always a good idea. 661838032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 661938032Speter is, it is possible to do a denial-of-service attack on 662038032Speter MX hosts that rely on the use of the null MX list. There 662138032Speter is no danger if you have this option turned off (the default). 662238032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 662338032Speter unsafe. I know of no specific attack against this, although 662438032Speter a denial-of-service attack is probably possible, but in theory 662538032Speter you should not be able to safely tweak anything that affects 662638032Speter the permissions that are used when mail is delivered. 662738032Speter Purgestat could go into an infinite loop if one of the host status 662838032Speter directories somehow became empty. Problem noted by Roy 662938032Speter Mongiovi of Georgia Tech. 663038032Speter Processes got "lost" when counting children due to a race condition. 663138032Speter This caused "proc_list_probe: lost pid" messages to be logged. 663238032Speter Problem noted by several people. 663338032Speter On systems with System V SIGCLD child signal semantics (notably AIX 663438032Speter and HP-UX), mail transactions would print the message "451 663538032Speter SMTP-MAIL: lost child: No child processes". Problem noted 663638032Speter by several people. 663738032Speter Miscellaneous compiler warnings on picky compilers (or when setting 663838032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 663938032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 664038032Speter not be persistent between runs, since they are based on the 664138032Speter message rather than the host. Problem noted by Matt Dillon 664238032Speter of Best Internet Communications. 664338032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 664438032Speter of NCR (a.k.a., AT&T Global Information Solutions). 664538032Speter Avoid the possibility of having a child daemon run to completion 664638032Speter (including closing the SMTP socket) before the parent has 664738032Speter had a chance to close the socket; this can cause the parent 664838032Speter to hang for a long time waiting for the socket to drain. 664938032Speter Patch from Don Lewis of TDK Semiconductor. 665038032Speter If the fork() failed in a queue run, the queue runners would not be 665138032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 665238032Speter Some error conditions in ETRN could cause output without an SMTP 665338032Speter status code. Problem noted by Don Lewis. 665438032Speter Multiple :maildrop addresses in the user database didn't work properly. 665538032Speter Patch from Roy Mongiovi of Georgia Tech. 665638032Speter Add ".db" automatically onto any user database spec that does not 665738032Speter already have it; this is for consistency with makemap, the 665838032Speter K line, and the documentation. Inconsistency pointed out 665938032Speter by Roy Mongiovi. 666038032Speter Allow sendmail to be properly called in nohup mode. Patch from 666138032Speter Kyle Jones of UUNET. 666238032Speter Change ETRN to ignore but still update host status files; previously 666338032Speter it would ignore them and not save the updated status, which 666438032Speter caused stale information to be maintained. Based on a patch 666538032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 666638032Speter ETRN ignore the MinQueueAge option. 666738032Speter Patch long term host status to recover more gracefully from an empty 666838032Speter host status file condition. Patch from NAKAMURA Motonori 666938032Speter of Kyoto University. 667038032Speter Several patches to signal handling code to fix potential race 667138032Speter conditions from Don Lewis. 667238032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 667338032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 667438032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 667538032Speter compile flag; use NETINET instead. Solution based on a 667638032Speter patch from Bryan Costales. 667738032Speter PORTABILITY FIXES: 667838032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 667938032Speter /etc/security/passwd file when called as root. This 668038032Speter is very slow on some systems. To speed it up, use the 668138032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 668238032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 668338032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 668438032Speter Glicker of Burrelle's Information Service. 668538032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 668638032Speter from Makoto MATSUSHITA of Osaka University. 668738032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 668838032Speter Leeds University and SASABE Tetsuro of the University 668938032Speter of Tokyo. 669038032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 669138032Speter Services, Inc. 669238032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 669338032Speter I believe this to have only been a problem if you 669438032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 669538032Speter to stick with /etc/sendmail.cf as your One True Path. 669638032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 669738032Speter Martin Laubach of the Technischen Universit�t Wien. 669838032Speter CONFIG: change default Received: line to be multiple lines rather 669938032Speter than one long one. By popular demand. 670038032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 670138032Speter from Jerome Berkman of U.C. Berkeley. 670238032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 670338032Speter to take a very long time. Problem noted by Yoshiro YONEYA 670438032Speter of NTT Software Corporation. 670538032Speter CONTRIB: add etrn.pl, contributed by John Beck. 670638032Speter NEW FILES: 670738032Speter contrib/etrn.pl 670838032Speter 670964562Sgshapiro8.8.3/8.8.3 1996/11/17 671038032Speter SECURITY: it was possible to get a root shell by lying to sendmail 671138032Speter about argv[0] and then sending it a signal. Problem noted 671238032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 671338032Speter best-of-security list. 671438032Speter Log sendmail binary version number in "Warning: .cf version level 671538032Speter (%d) exceeds program functionality (%d) message" -- this 671638032Speter should make it clearer to people that they are running 671738032Speter the wrong binary. 671838032Speter Fix a problem that occurs when you open an SMTP connection and then 671938032Speter do one or more ETRN commands followed by a MAIL command; at 672038032Speter the end of the DATA phase sendmail would incorrectly report 672138032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 672238032Speter noted by Eric Bishop of Virginia Tech. 672338032Speter When doing text-based host canonification (typically /etc/hosts 672438032Speter lookup), a null host name would match any /etc/hosts entry 672538032Speter with space at the end of the line. Problem noted by Steve 672638032Speter Hubert of the University of Washington, Seattle. 672738032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 672838032Speter Problem reported by Tom Smith of Digital Equipment Corp. 672938032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 673038032Speter size PACKETSZ (512) is not sufficient for some nameserver 673138032Speter answers containing very many resource records. The resolver 673238032Speter may also switch to TCP and retry if it detects UDP packet 673338032Speter overflow. Also, allow for the fact that the resolver 673438032Speter routines res_query and res_search return the size of the 673538032Speter *un*truncated answer in case the supplied answer buffer it 673638032Speter not big enough to accommodate the entire answer. Patch from 673738032Speter Eric Wassenaar. 673838032Speter Improvements to MaxDaemonChildren code. If you think you have too 673938032Speter many children, probe the ones you have to verify that they 674038032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 674138032Speter Also, do this probe before growing the vector of children 674238032Speter pids; this previously caused the vector to grow indefinitely 674338032Speter due to a race condition. Problem reported by Kyle Jones of 674438032Speter UUNET. 674538032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 674638032Speter O_EXLOCK to zero; this fools the map compilation code into 674738032Speter thinking that it can avoid race conditions by locking on open. 674838032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 674938032Speter Leif Erlingsson of Data Lege. 675038032Speter Always call res_init() on startup (if compiled in, of course) to 675138032Speter allow the sendmail.cf file to tweak resolver flags; without 675238032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 675338032Speter Andrew Sun of Merrill Lynch. 675438032Speter Improvements to host status printing code. Suggested by Steve Hubert 675538032Speter of the University of Washington, Seattle. 675638032Speter Change MinQueueAge option processing to do the check for the job age 675738032Speter when reading the queue file, rather than at the end; this 675838032Speter avoids parsing the addresses, which can do DNS lookups. 675938032Speter Problem noted by John Beck of InReference, Inc. 676038032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 676138032Speter properly escaped. Problem noted by Peter Nilsson of the 676238032Speter University of Linkoping. 676338032Speter In some cases, sendmail would retain root permissions during queue 676438032Speter runs even if RunAsUser was set. Problem noted by Mark 676538032Speter Thomas of Mark G. Thomas Consulting. 676638032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 676738032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 676838032Speter the envelope, and the receiving SMTP server speaks DSN, then 676938032Speter the DSN would be both generated locally and propagated to the 677038032Speter other end. 677138032Speter The U= mailer field didn't correctly extract the group id if the 677238032Speter user id was numeric. Problem noted by Kenneth Herron of 677338032Speter MCI Telecommunications Communications. 677438032Speter If a message exceeded the fixed maximum size on input, the body of 677538032Speter the message was included in the bounce. Note that this did 677638032Speter not occur if it exceeded the maximum _output_ size. Problem 677738032Speter reported by Kyle Jones of UUNET. 677838032Speter PORTABILITY FIXES: 677938032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 678038032Speter AIX4 defines to use seteuid(2) instead, which 678138032Speter works on 4.1 as well as 4.2. Problem noted by 678238032Speter H�kan Lindholm of interAF, Sweden. 678338032Speter AIX4: use tzname[] vector to determine time zone name. 678438032Speter Patch from NAKAMURA Motonori of Kyoto University. 678538032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 678638032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 678738032Speter Solaris: kstat(3k) support for retrieving the load average. 678838032Speter This adds the LA_KSTAT definition for LA_TYPE. 678938032Speter The outline of the implementation was contributed 679038032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 679138032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 679238032Speter declaration of struct rusage at the top of conf.h; 679338032Speter change it to only be included if you are using gcc, 679438032Speter which is apparently the only compiler that requires 679538032Speter it in the first place. Problem noted by Jeff 679638032Speter Earickson of Colby College. 679738032Speter IRIX: don't default to using gcc. IRIX is a civilized 679838032Speter operating system that comes with a decent compiler 679938032Speter by default. Problem noted by Barry Bouwsma and 680038032Speter Kari Hurtta. 680138032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 680238032Speter consistency with other local mailers. Inconsistency 680338032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 680438032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 680538032Speter overhead) as part of the bestmx_is_local feature, the 680638032Speter domain part was dropped from the name. Patch from Steve 680738032Speter Hubert of the University of Washington, Seattle. 680838032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 680938032Speter end up being translated to the null host name, which would 681038032Speter return any entry in /etc/hosts that had a space at the end 681138032Speter of the line. Problem noted by Steve Hubert of the 681238032Speter University of Washington, Seattle. 681338032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 681438032Speter Polytechnic Institute. 681538032Speter MAKEMAP: tweak hash and btree parameters for better performance. 681638032Speter Patch from Matt Dillon of Best Internet Communications. 681738032Speter NEW FILES: 681838032Speter src/Makefiles/Makefile.Linux.ppc 681938032Speter cf/ostype/aix4.m4 682038032Speter cf/ostype/mklinux.m4 682138032Speter 682264562Sgshapiro8.8.2/8.8.2 1996/10/18 682338032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 682438032Speter changed the code but didn't fix the problem. 682538032Speter PORTABILITY FIXES: 682638032Speter Solaris: Don't use the system getusershell(3); it can 682738032Speter apparently corrupt the heap in some circumstances. 682838032Speter Problem found by Ken Pizzini of Spry, Inc. 682938032Speter OP.ME: document several mailer flags that were accidentally omitted 683038032Speter from this document.

Problem noted 683638032Speter by Dan Bernstein of the University of Illinois at Chicago. 683738032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 683838032Speter message could overflow a buffer if it was converted back 683938032Speter to 8 bits. This caused core dumps and has the potential 684038032Speter for a remote attack. Problem first noted by Gregory Shapiro 684138032Speter of WPI. 684238032Speter Avoid duplicate deliveries of error messages on systems that don't 684338032Speter have flock(2) support. Patch from Motonori Nakamura of 684438032Speter Kyoto University. 684538032Speter Ignore null FallBackMX (V) options. If this option is null (as 684638032Speter opposed to undefined) it can cause "null signature" syserrs 684738032Speter on illegal host names. 684838032Speter If a Base64 encoded text/plain message has no trailing newline in 684938032Speter the encoded text, conversion back to 8 bits will drop the 685038032Speter final line. Problem noted by Pierre David. 685138032Speter If running with a RunAsUser, sendmail would give bogus "cannot 685238032Speter setuid" (or seteuid, or setreuid) messages on some systems. 685338032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 685438032Speter Always print error messages in -bv mode -- previously, -bv would 685538032Speter be absolutely silent on errors if the error mode was sent 685638032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 685738032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 685838032Speter term host status. This is necessary because it is common 685938032Speter to do this when you know a host has just come back up. 686038032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 686138032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 686238032Speter University of Leicester. 686338032Speter If a service (such as NIS) is specified as the last entry in the 686438032Speter service switch, but that service is not compiled in, sendmail 686538032Speter would return a temporary failure when an entry was not found 686638032Speter in the map. This caused the message to be queued instead of 686738032Speter bouncing immediately. Problem noted by Harry Edmon of the 686838032Speter University of Washington. 686938032Speter PORTABILITY FIXES: 687038032Speter Solaris 2.3 had compilation problems in conf.c. Several 687138032Speter people pointed this out. 687238032Speter NetBSD from Charles Hannum of MIT. 687338032Speter AIX4 improvements based on info from Steve Bauer of South 687438032Speter Dakota School of Mines & Technology. 687538032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 687638032Speter Patch from Gil Kloepfer Jr. 687738032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 687838032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 687938032Speter were also in $=w. Problem noted by Zoltan Basti of 688038032Speter Softec. 688138032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 688238032Speter on a patch from Eric Hagberg of Morgan Stanley. 688338032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 688438032Speter of Stanford via Robert La Ferla. 688538032Speter 688664562Sgshapiro8.8.0/8.8.0 1996/09/26 688738032Speter Under some circumstances, Bcc: headers would not be properly 688838032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 688938032Speter Log a warning if the sendmail daemon is invoked without a full 689038032Speter pathname, which prevents "kill -1" from working. I was 689138032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 689238032Speter Fix small buffer overflow. Since the data in this buffer was not 689338032Speter read externally, there was no security problem (and in fact 689438032Speter probably wouldn't really overflow on most compilers). Pointed 689538032Speter out by KIZU takashi of Osaka University. 689638032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 689738032Speter if a FallbackMXHost was specified in the configuration file 689838032Speter -- all mail would be sent to the fallback even if the original 689938032Speter host was accessible. Pointed out by Munenari Hirayama of 690038032Speter NSC (Japan). 690138032Speter A message that didn't terminate with a newline would (sometimes) not 690238032Speter have the trailing "." added properly in the SMTP dialogue, 690338032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 690438032Speter The DaemonPortOptions suboption to bind to a particular address was 690538032Speter incorrect and nonfunctional due to a misunderstanding of the 690638032Speter semantics of binding on a passive socket. Patch from 690738032Speter NIIBE Yutaka of Mitsubishi Research Institute. 690838032Speter Increase the number of MX hosts for a single name to 100 to better 690938032Speter handle the truly huge service providers such as AOL, which 691038032Speter has 13 at the moment (and climbing). In order to avoid 691138032Speter trashing memory, the buffer for all names has only been 691238032Speter slightly increased in size, to 12.8K from 10.2K -- this means 691338032Speter that if a single name had 100 MX records, the average size 691438032Speter of those records could not exceed 128 bytes. Requested by 691538032Speter Brad Knowles of America On Line. 691638032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 691738032Speter Urged by Dan Bernstein of U.C. Berkeley. 691838032Speter Print q_statdate and q_specificity in address structure debugging 691938032Speter printout. 692038032Speter Expand MCI structure flag bits for debugging output. 692138032Speter Support IPv6-style domain literals, which can have colons between 692238032Speter square braces. 692338032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 692438032Speter this is an attempt to track down a bug that one person seems 692538032Speter to be having (it may be a Solaris bug!). 692638032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 692738032Speter this caused the NOTIFY info to sometimes be lost. Problem 692838032Speter pointed out by Claus Assmann of the 692938032Speter Christian-Albrechts-University of Kiel. 693038032Speter The statistics gathered in the sendmail.st file were too high; in 693138032Speter some cases failures (e.g., user unknown or temporary failure) 693238032Speter would count as a delivery as far as the statistics were 693338032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 693438032Speter Systems that don't have flock() would not send split envelopes in 693538032Speter the initial run. Problem pointed out by Leonard Zubkoff of 693638032Speter Dandelion Digital. 693738032Speter Move buffer overflow checking -- these primarily involve distrusting 693838032Speter results that may come from NIS and DNS. 693938032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 694038032Speter include <paths.h> and hence had the wrong pathnames for a few 694138032Speter things like /var/tmp. Reported by Matthew Green. 694238032Speter Conditions were reversed for the Priority: header, resulting in all 694338032Speter values being interpreted as non-urgent except for non-urgent, 694438032Speter which was interpreted as normal. Patch from Bryan Costales. 694538032Speter The -o (optional) flag was being ignored on hash and btree maps 694638032Speter since 8.7.2. Fix from Bryan Costales. 694738032Speter Content-Types listed in class "q" will always be encoded as 694838032Speter Quoted-Printable (or more accurately, will never be encoded 694938032Speter as base64). The class can have primary types (e.g., "text") 695038032Speter or full types (e.g., "text/plain"). Based on a suggestion by 695138032Speter Marius Olafsson of the University of Iceland. 695238032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 695338032Speter dialogue) so it can be passed to programs in mailers. 695438032Speter Define ${bodytype} to be the body type (from the -B flag or the 695538032Speter BODY= ESMTP parameter) so it can be passed to programs in 695638032Speter mailers. 695738032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 695838032Speter flag is set in the mailer descriptor. Suggested by John 695938032Speter Myers of CMU. 696038032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 696138032Speter The command takes a host name; data for that host is 696238032Speter immediately (and asynchronously) flushed. Because this shares 696338032Speter the -qR implementation, other hosts may be attempted, but 696438032Speter there should be no security implications. Implementation 696538032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 696638032Speter Add three new command line flags to pass in DSN parameters: -V envid 696738032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 696838032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 696938032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 697038032Speter that the -N flag applies to all recipients; there is no way 697138032Speter to specify per-address notifications on the command line, 697238032Speter nor is there an equivalent for the ORCPT= per-address 697338032Speter parameter. 697438032Speter Restore LogLevel option to be safe (it can only be increased); 697538032Speter apparently I went into paranoid mode between 8.6 and 8.7 697638032Speter and made it unsafe. Pointed out by Dabe Murphy of the 697738032Speter University of Maryland. 697838032Speter New logging on log level 15: all SMTP traffic. Patches from 697938032Speter Andrew Gross of San Diego Supercomputer Center. 698038032Speter NetInfo property value searching code wasn't stopping when it found 698138032Speter a match. This was causing the wrong values to be found (and 698238032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 698338032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 698438032Speter out by Bill Wisner of Electronics for Imaging that you can't 698538032Speter use the bracket address form for the MAIL_HUB macro, since 698638032Speter that causes the brackets to remain in the envelope recipient 698738032Speter address used for delivery. The simple fix (stripping off the 698838032Speter brackets in the config file) breaks the use of IP literal 698938032Speter addresses. This flag will solve that problem. 699038032Speter Add MustQuoteChars option. This is a list of characters that must 699138032Speter be quoted if they are found in the phrase part of an address 699238032Speter (that is, the full name part). The characters @,;:\()[] are 699338032Speter always in this list and cannot be removed. The default is 699438032Speter this list plus . and ' to match RFC 822. 699538032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 699638032Speter that do not include a host name for back compatibility with 699738032Speter some stupid SMTP clients. Setting this violates RFC 1123 699838032Speter section 5.2.5. 699938032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 700038032Speter rejecting connections if it has more than this many 700138032Speter outstanding children accepting mail. Note that you may 700238032Speter see more processes than this because of outgoing mail; this 700338032Speter is for incoming connections only. 700438032Speter Add ConnectionRateThrottle option. If set to a positive value, the 700538032Speter number of incoming SMTP connections that will be permitted 700638032Speter in a single second is limited to this number. Connections are 700738032Speter not refused during this time, just deferred. The intent is to 700838032Speter flatten out demand so that load average limiting can kick in. 700938032Speter It is less radical than MaxDaemonChildren, which will stop 701038032Speter accepting connections even if all the connections are idle 701138032Speter (e.g., due to connection caching). 701238032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 701338032Speter specifies how long cached information about the state of a 701438032Speter host will be kept before they are considered stale and the 701538032Speter host is retried. If you are using persistent host status 701638032Speter (i.e., the HostStatusDirectory option is set) this will apply 701738032Speter between runs; otherwise, it applies only within a single queue 701838032Speter run and hence is useful only for hosts that have large queues 701938032Speter that take a very long time to run. 702038032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 702138032Speter into being a single line even if they had newlines in them 702238032Speter when read. This is to get around a botch in Lotus Notes. 702338032Speter Text class maps were totally broken -- if you ever retrieved the last 702438032Speter item in a table it would be truncated. Problem noted by 702538032Speter Gregory Neil Shapiro of WPI. 702638032Speter Extend the lines printed by the mailq command (== the -bp flag) when 702738032Speter -v is given to 120 characters; this allows more information 702838032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 702938032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 703038032Speter this was treated as end-of-input. Problem noted by Bryan 703138032Speter Costales. 703238032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 703338032Speter to the queue file. Fix from John Hughes of Atlantic 703438032Speter Technologies, Inc. 703538032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 703638032Speter if this happens in a queue run it can cause nasty delays. 703738032Speter Problem noted by Mark Horton of AT&T. 703838032Speter If userdb entries pointed to userdb entries, and there were multiple 703938032Speter values for a given key, the database cursor would get 704038032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 704138032Speter of Georgia Tech. Fixed by reading all the values and creating 704238032Speter a comma-separated list; thus, the -v output will be somewhat 704338032Speter different for this case. 704438032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 704538032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 704638032Speter of Stanford University. 704738032Speter When envelopes were split due to aliases with owner- aliases, and 704838032Speter there was some error on one of the lists, more than one of 704938032Speter the owners would get the message. Problem pointed out by 705038032Speter Roy Mongiovi of Georgia Tech. 705138032Speter Detect excessive recursion in macro expansions, e.g., $X defined 705238032Speter in terms of $Y which is defined in terms of $X. Problem 705338032Speter noted by Bryan Costales; patch from Eric Wassenaar. 705438032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 705538032Speter some cases get trashed causing bogus From_ lines. Fix from 705638032Speter Kyle Jones of UUNET. 705738032Speter When doing load average initialization, if the nlist call for avenrun 705838032Speter failed, the second and subsequent lookups wouldn't notice 705938032Speter that fact causing bogus load averages to be returned. Noted 706038032Speter by Casper Dik of Sun Holland. 706138032Speter Fix problem with incompatibility with some versions of inet_aton that 706238032Speter have changed the return value to unsigned, so a check for an 706338032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 706438032Speter This could cause mail to addresses such as [foo.com] to bounce 706538032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 706638032Speter Pasteur Institute. 706738032Speter DSNs were inconsistent if a failure occurred during the DATA phase 706838032Speter rather than the RCPT phase: the Action: would be correct, but 706938032Speter the detailed status information would be wrong. Problem noted 707038032Speter by Bob Snyder of General Electric Company. 707138032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 707238032Speter that this is the initial MUA->MTA submission. The flag current 707338032Speter does nothing, but in future releases (when MUAs start using 707438032Speter these flags) it will probably turn on things like DNS 707538032Speter canonification. 707638032Speter Default end-of-line string (E= specification on mailer [M] lines) 707738032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 707838032Speter mailers. 707938032Speter Change the internal definition for the *file* and *include* mailers 708038032Speter to have $u in the argument vectors so that they aren't 708138032Speter misinterpreted as SMTP mailers and thus use \r\n line 708238032Speter termination. This will affect anyone who has redefined 708338032Speter either of these in their configuration file. 708438032Speter Don't assume that IDENT servers close the connection after a query; 708538032Speter responses can be newline terminated. From Terry Kennedy of 708638032Speter St. Peter's College. 708738032Speter Avoid core dumps on erroneous configuration files that have 708838032Speter $#mailer with nothing following. From Bryan Costales. 708938032Speter Avoid null pointer dereference with high debug values in unlockqueue. 709038032Speter Fix from Randy Martin of Clemson University. 709138032Speter Fix possible buffer overrun when expanding very large macros. Fix 709238032Speter from Kyle Jones of UUNET. 709338032Speter After 25 EXPN or VRFY commands, start pausing for a second before 709438032Speter processing each one. This avoids a certain form of denial 709538032Speter of service attack. Potential attack pointed out by Bryan 709638032Speter Costales. 709738032Speter Allow new named (not numbered!) config file rules to do validity 709838032Speter checking on SMTP arguments: check_mail for MAIL commands and 709938032Speter check_rcpt for RCPT commands. These rulesets can do anything 710038032Speter they want; their result is ignored unless they resolve to the 710138032Speter $#error mailer, in which case the indicated message is printed 710238032Speter and the command is rejected. Similarly, the check_compat 710338032Speter ruleset is called before delivery with "from_addr $| to_addr" 710438032Speter (the $| is a meta-symbol used to separate the two addresses); 710538032Speter it can give a "this sender can't send to this recipient" 710638032Speter notification. Note that this patch allows $| to stand alone 710738032Speter in rulesets. 710838032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 710938032Speter that have the name, IP address, and port number (respectively) 711038032Speter of the SMTP client (that is, the entity at the other end of 711138032Speter the connection. These can be used in (e.g.) check_rcpt to 711238032Speter verify that someone isn't trying to relay mail through your 711338032Speter host inappropriately. Be sure to use the deferred evaluation 711438032Speter form, for example $&{client_name}, to avoid having these bound 711538032Speter when sendmail reads the configuration file. 711638032Speter Add new config file rule check_relay to check the incoming connection 711738032Speter information. Like check_compat, it is passed the host name 711838032Speter and host address separated by $| and can reject connections 711938032Speter on that basis. 712038032Speter Allow IDA-style recursive function calls. Code contributed by Mark 712138032Speter Lovell and Paul Vixie. 712238032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 712338032Speter a virtual UUCP address using either a domain address or the $k 712438032Speter macro. Based on code contributed by Mark Lovell and Paul 712538032Speter Vixie. 712638032Speter Add Stanford LDAP map. Requires special libraries that are not 712738032Speter included with sendmail. Contributed by Booker C. Bense 712838032Speter <bbense@networking.stanford.edu>; contact him for support. 712938032Speter See also the src/READ_ME file. 713038032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 713138032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 713238032Speter only for debugging deep bits of code where it is important to 713338032Speter distinguish between the single-character metasymbol $+ and the 713438032Speter two characters $, +. 713538032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 713638032Speter debug_dumpstate. 713738032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 713838032Speter files that are group writable are considered "unsafe" -- that 713938032Speter is, programs and files referenced from such files are not 714038032Speter valid recipients. 714138032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 714238032Speter name that was not in DNS or was a domain-literal. Problem 714338032Speter noted by Tom May. 714438032Speter Change the introduction to error messages to more clearly delineate 714538032Speter permanent from temporary failures; if both existed in a 714638032Speter single message it could be confusing. Suggested by John 714738032Speter Beck of InReference, Inc. 714838032Speter The IngoreDot (i) option didn't work for lines that were terminated 714938032Speter with CRLF. Problem noted by Ted Stockwell of Secure 715038032Speter Computing Corporation. 715138032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 715238032Speter message headers. Problem reported by Matt Dillon of Best 715338032Speter Internet Communications. 715438032Speter Check for bogus characters in the 0200-0237 range; since these are 715538032Speter used internally, very strange errors can occur if those 715638032Speter characters appear in headers. Problem noted by Anders Gertz 715738032Speter of Lysator. 715838032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 715938032Speter recipient mailer has the F=9 flag set, and only works on 716038032Speter text/plain body types. Code contributed by Marius Olafsson 716138032Speter of the University of Iceland. 716238032Speter Special case "postmaster" name so that it is always treated as lower 716338032Speter case in alias files regardless of configuration settings; 716438032Speter this prevents some potential problems where "Postmaster" or 716538032Speter "POSTMASTER" might not match "postmaster". In most cases 716638032Speter this change is a no-op. 716738032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 716838032Speter Costales. 716938032Speter The -a map flag was ignored for dequote maps. Problem noted by 717038032Speter Bryan Costales. 717138032Speter Fix core dump when a lookup of a class "prog" map returns no 717238032Speter response. Patch from Bryan Costales. 717338032Speter Log instances where sendmail is deferring or rejecting connections 717438032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 717538032Speter Include port number in process title for network daemons. Suggested 717638032Speter by Kyle Jones of UUNET. 717738032Speter Send ``double bounces'' (errors that occur when sending an error 717838032Speter message) to the address indicated in the DoubleBounceAddress 717938032Speter option (default: postmaster). Previously they were always 718038032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 718138032Speter Add new mode, -bD, that acts like -bd in all respects except that 718238032Speter it runs in foreground. This is useful for using with a 718338032Speter wrapper that "watches" system services. Suggested by Kyle 718438032Speter Jones of UUNET. 718538032Speter Fix botch in spacing around (parenthesized) comments in addresses 718638032Speter when the comment comes before the address. Patch from 718738032Speter Motonori Nakamura of Kyoto University. 718838032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 718938032Speter that are being bounced to postmaster, rather than "Returned 719038032Speter mail". This permits the person who is postmaster more 719138032Speter easily determine what messages are to their role as 719238032Speter postmaster versus bounces to mail they actually sent. Based 719338032Speter on a suggestion by Motonori Nakamura. 719438032Speter Add new value "time" for QueueSortOrder option; this causes the queue 719538032Speter to be sorted strictly by the time of submission. Note that 719643730Speter this can cause very bad behavior over slow lines (because 719738032Speter large jobs will tend to delay small jobs) and on nodes with 719838032Speter heavy traffic (because old things in the queue for hosts that 719938032Speter are down delay processing of new jobs). Also, this does not 720038032Speter guarantee that jobs will be delivered in submission order 720138032Speter unless you also set DeliveryMode=queue. In general, it should 720238032Speter probably only be used on the command line, and only in 720338032Speter conjunction with -qRhost.domain. In fact, there are very few 720438032Speter cases where it should be used at all. Based on an 720538032Speter implementation by Motonori Nakamura. 720638032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 720738032Speter the same manner as other rulesets. Previously a temporary 720838032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 720938032Speter of Stanford University. 721038032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 721138032Speter 5yz (permanent failure) code. The next MX host will still be 721238032Speter tried if the connection cannot be opened in the first place 721338032Speter or if the MAIL command returns a 4yz (temporary failure) code. 721438032Speter (It's hard to know what to do here, since neither RFC 974 nor 721538032Speter RFC 1123 specify when to proceed to the next MX host.) 721638032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 721738032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 721838032Speter This causes map lookups that get a temporary failure (e.g., 721938032Speter name server failure) to _not_ defer the delivery of the 722038032Speter message. This should only be used if your configuration file 722138032Speter is prepared to do something sensible in this case. Based on 722238032Speter an idea by Gregory Shapiro of WPI. 722338032Speter Fix problem finding network interface addresses. Patch from 722438032Speter Motonori Nakamura. 722538032Speter Don't reject qf entries that are not owned by your effective uid if 722690792Sgshapiro you are not running set-user-ID; this makes management of 722780785Sgshapiro certain kinds of firewall setups difficult. Patch 722880785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 722938032Speter Add persistent host status. This keeps the information normally 723038032Speter maintained within a single queue run in disk files that are 723138032Speter shared between sendmail instances. The HostStatusDirectory 723238032Speter is the directory in which the information is maintained. If 723338032Speter not set, persistent host status is turned off. If not a full 723438032Speter pathname, it is relative to the queue directory. A common 723538032Speter value is ".hoststat". 723638032Speter There are also two new operation modes: 723738032Speter * -bh prints the status of hosts that have had recent 723838032Speter connections. 723938032Speter * -bH purges the host statuses. No attempt is made to save 724038032Speter recent status information. 724138032Speter This feature was originally written by Paul Vixie of Vixie 724238032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 724338032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 724438032Speter with my insistence that things fit cleanly into the V8 724538032Speter framework is gratefully appreciated. 724638032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 724738032Speter operate). Avoids letting two sendmails on the local machine 724864562Sgshapiro open connections to the same remote host at the same time. 724938032Speter This reduces load on the other machine, but can cause mail to 725038032Speter be delayed (for example, if one sendmail is delivering a huge 725138032Speter message, other sendmails won't be able to send even small 725238032Speter messages). Also, it requires another file descriptor (for the 725338032Speter lock file) per connection, so you may have to reduce 725438032Speter ConnectionCacheSize to avoid running out of per-process 725538032Speter file descriptors. Based on the persistent host status code 725638032Speter contributed by Paul Vixie and Mark Lovell. 725738032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 725838032Speter SafeFileEnvironment option is set. Problem noted by Bryan 725938032Speter Costales. 726038032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 726138032Speter file. Problem noted by Bryan Costales. 726238032Speter If a job was aborted using the interrupt signal (e.g., control-C from 726338032Speter the keyboard), on some occasions an empty df file would be 726438032Speter left around; these would collect in the queue directory. 726538032Speter Problem noted by Bryan Costales. 726638032Speter Change the makesendmail script to enhance the search for Makefiles 726738032Speter based on release number. For example, on SunOS 5.5.1, it will 726838032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 726938032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 727038032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 727138032Speter Webmasters. 727238032Speter When creating maps using "newaliases", always map the keys to lower 727338032Speter case when creating the map unless the -f flag is specified on 727438032Speter the map itself. Previously this was done based on the F=u 727538032Speter flag in the local mailer, which meant you could create aliases 727638032Speter that you could never access. Problem noted by Bob Wu of DEC. 727738032Speter When a job was read from the queue, the bits causing notification on 727838032Speter failure or delay were always set. This caused those 727938032Speter notifications to be sent even if NOTIFY=NEVER had been 728038032Speter specified. Problem noted by Steve Hubert of the University 728138032Speter of Washington, Seattle. 728238032Speter Add new configurable routine validate_connection (in conf.c). This 728338032Speter lets you decide if you are willing to accept traffic from 728438032Speter this host. If it returns FALSE, all SMTP commands will return 728538032Speter "550 Access denied". -DTCPWRAPPERS will include support for 728638032Speter TCP wrappers; you will need to add -lwrap to the link line. 728738032Speter (See src/READ_ME for details.) 728838032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 728938032Speter bounces. Some people seemed to think that this could be 729038032Speter confusing (even though it is true). Suggested by Motonori 729138032Speter Nakamura. 729238032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 729338032Speter user early in processing to avoid potential security problems. 729438032Speter However, this means that all .forward and :include: files must 729538032Speter be readable by that user, and all files to be written must be 729638032Speter writable by that user and all programs will be executed by that 729738032Speter user. It is also incompatible with the SafeFileEnvironment 729838032Speter option. In other words, it may not actually add much to 729938032Speter security. However, it should be useful on firewalls and other 730038032Speter places where users don't have accounts and the aliases file is 730138032Speter well constrained. 730238032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 730338032Speter only on the first attempt to delivery to an address. It could 730438032Speter be set to be lower than Timeout.connect on the principle that 730538032Speter the mail should go through quickly to responsive hosts; less 730638032Speter responsive hosts get to wait for the next queue run. 730738032Speter Fix a problem on Solaris that occasionally causes programs 730838032Speter (such as vacation) to hang with their standard input connected 730938032Speter to a UDP port. It also created some signal handling problems. 731038032Speter The problems turned out to be an interaction between vfork(2) 731138032Speter and some of the libraries, particularly NIS/NIS+. I am 731238032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 731338032Speter Change user class map to do the same matching that actual delivery 731438032Speter will do instead of just a /etc/passwd lookup. This adds 731538032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 731638032Speter The Timeout.* options are not safe -- they can be used to create a 731738032Speter denial-of-service attack. Problem noted by Christophe 731838032Speter Wolfhugel. 731943730Speter Don't send PostmasterCopy messages in the event of a "delayed" 732038032Speter notification. Suggested by Barry Bouwsma. 732138032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 732238032Speter option is set, since this disables VERB mode. Suggested 732338032Speter by John Hawkinson of MIT. 732438032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 732538032Speter by Motonori Nakamura of Kyoto University. 732638032Speter Only queue messages on transient .forward open failures if there 732743730Speter were no successful opens. The previous behavior caused it 732838032Speter to queue even if a "fall back" .forward was found. Problem 732938032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 733038032Speter and Computer Science (DISCS), NUS, Singapore. 733138032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 733238032Speter is bouncing because of a MIME error during 8->7 bit conversion; 733338032Speter the encapsulated message will bounce again, causing a loop. 733438032Speter Problem noted by Steve Hubert of the University of Washington. 733538032Speter Create xf (transcript) files using the TempFileMode option value 733638032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 733738032Speter National University of Singapore. 733838032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 733938032Speter detect cases where DefaultUid is set to something that the 734038032Speter system can't cope with. 734138032Speter PORTABILITY FIXES: 734238032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 734338032Speter Atlas International. 734438032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 734538032Speter <bicknell@ufp.org>. 734638032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 734738032Speter work on the first recipient of a message due to a 734838032Speter bug in the getpwent family.

Based on a patch from Randall 739138032Speter Winchester of the University of Maryland. 739238032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 739338032Speter Robert La Ferla of Hot Software. 739438032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 739538032Speter (where "code" is an exit status) on domains (previously 739638032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 739738032Speter Foundation. 739838032Speter CONFIG: hooks for IPv6-style domain literals. 739938032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 740038032Speter if it is undefined the AliasFile option is never set; this 740138032Speter should be transparent for most everyone. Suggested by John 740238032Speter Myers of CMU. 740338032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 740438032Speter domain listed in $=w is masqueraded. With it, only those 740538032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 740638032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 740738032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 740838032Speter hosts under those domains as well as the domain headers 740938032Speter themselves. For example, if a configuration had 741038032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 741138032Speter foo.com would be masqueraded; with it, *.foo.com would be 741238032Speter masqueraded as well. Based on an implementation by Richard 741338032Speter (Pug) Bainter of U. Texas. 741438032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 741538032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 741638032Speter Keys are user names; values are outgoing mail addresses. Yes, 741738032Speter this does overlap with the user database, and figuring out 741838032Speter just when to use which one may be tricky. Based on code 741938032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 742038032Speter from Per Hedeland of Ericsson. 742138032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 742238032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 742338032Speter Keys are either fully qualified addresses or just the host 742438032Speter part (with the @ sign). For example, a table containing: 742538032Speter info@foo.com foo-info 742638032Speter info@bar.com bar-info 742738032Speter @baz.org jane@elsewhere.net 742838032Speter would send all mail destined for info@foo.com to foo-info 742938032Speter (which is presumably an alias), mail addressed to info@bar.com 743038032Speter to bar-info, and anything addressed to anyone at baz.org will 743138032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 743238032Speter and baz.org must all be in $=w. Based on discussions with 743338032Speter a great many people. 743438032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 743538032Speter Suggested by Richard Bainter. 743638032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 743738032Speter "fax" mailer. 743838032Speter CONFIG: allow mailertable entries to resolve to local:user; this 743938032Speter passes the original user@host in to procmail-style local 744038032Speter mailers as the "detail" information to allow them to do 744138032Speter additional clever processing. From Joe Pruett of 744238032Speter Teleport Corporation. Delivery to the original user can 744338032Speter be done by specifying "local:" (with nothing after the colon). 744438032Speter CONFIG: allow any context that takes "mailer:domain" to also take 744538032Speter "mailer:user@domain" to force mailing to the given user; 744638032Speter "local:user" can also be used to do local delivery. This 744738032Speter applies on *_RELAY and in the mailertable entries. Based 744838032Speter on a suggestion by Ribert Kiessling of Easynet. 744938032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 745038032Speter limits the possible domains; this reduces the number of DNS 745138032Speter lookups required to support this feature. For example, 745238032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 745338032Speter to domains under my.site.com. Code contributed by Anthony 745438032Speter Thyssen <anthony@cit.gu.edu.au>. 745538032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 745638032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 745738032Speter of WPI. 745838032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 745938032Speter event you have to define local mailers. Suggested by 746038032Speter Gregory Shapiro of WPI. 746138032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 746238032Speter be misinterpreted as a list:...; syntax. Based on a patch by 746338032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 746438032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 746538032Speter remotely connected. The address host!user was being 746638032Speter converted to host!user@thishost instead of host!user@uurelay. 746738032Speter Problem noted by William Gianopoulos of Raytheon Company. 746838032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 746938032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 747038032Speter "User has moved"; the former wording was confusing if the 747138032Speter new address is still on the local host. Based on a suggestion 747238032Speter by Andreas Luik. 747338032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 747438032Speter However, the class is not pre-initialized to contain root. 747538032Speter Suggested by Gregory Neil Shapiro. 747638032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 747738032Speter Wolfhugel. 747838032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 747938032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 748038032Speter well: this produces a slightly different mailbox format (no 748138032Speter Content-Length: headers), file ownerships and modes are 748238032Speter different (not owned by group mail; mode 600 instead of 660), 748338032Speter and the local mailer flags will have to be tweaked (make them 748438032Speter match bsd4.4) in order to use this mailer. Patches from Paul 748538032Speter Hammann of the Missouri Research and Education Network. 748638032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 748738032Speter was a delivery error, such as if the ownership on the file 748838032Speter was wrong or the mode changed between the initial stat and 748938032Speter the open. Problem reported by William Colburn of the New 749038032Speter Mexico Institute of Mining and Technology. 749138032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 749238032Speter Costales. 749338032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 749438032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 749538032Speter honored. Fix from Michael Scott Shappe. 749638032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 749738032Speter NEW FILES: 749838032Speter src/Makefiles/Makefile.AIX.2 749938032Speter src/Makefiles/Makefile.IRIX.6.2 750038032Speter src/Makefiles/Makefile.maxion 750138032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 750238032Speter src/Makefiles/Makefile.SCO.5.x 750338032Speter src/Makefiles/Makefile.UXPDSV20 750438032Speter mailstats/mailstats.8 750538032Speter praliases/praliases.8 750638032Speter cf/cf/generic-nextstep3.3.mc 750738032Speter cf/feature/genericstable.m4 750838032Speter cf/feature/limited_masquerade.m4 750938032Speter cf/feature/masquerade_entire_domain.m4 751038032Speter cf/feature/virtusertable.m4 751138032Speter cf/ostype/aix2.m4 751238032Speter cf/ostype/altos.m4 751338032Speter cf/ostype/maxion.m4 751438032Speter cf/ostype/solaris2.ml.m4 751538032Speter cf/ostype/uxpds.m4 751638032Speter contrib/re-mqueue.pl 751738032Speter DELETED FILES: 751838032Speter src/Makefiles/Makefile.Solaris 751938032Speter contrib/xla/README 752038032Speter contrib/xla/xla.c 752138032Speter RENAMED FILES: 752238032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 752338032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 752438032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 752538032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 752638032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 752738032Speter 752864562Sgshapiro8.7.6/8.7.3 1996/09/17 752938032Speter SECURITY: It is possible to force getpwuid to fail when writing the 753038032Speter queue file, causing sendmail to fall back to running programs 753138032Speter as the default user. This is not exploitable from off-site. 753238032Speter Workarounds include using a unique user for the DefaultUser 753338032Speter (old u & g options) and using smrsh as the local shell. 753438032Speter SECURITY: fix some buffer overruns; in at least one case this allows 753538032Speter a local user to get root. This is not known to be exploitable 753638032Speter from off-site. The workaround is to disable chfn(1) commands. 753738032Speter 753864562Sgshapiro8.7.5/8.7.3 1996/03/04 753938032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 754038032Speter in some case cause connections to hang or messages to have 754138032Speter extra spaces in odd places. Patch from Eric Wassenaar; 754238032Speter reports from Eric Hall of Chiron Corporation, Stephen 754338032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 754438032Speter and others. 754538032Speter 754664562Sgshapiro8.7.4/8.7.3 1996/02/18 754738032Speter SECURITY: In some cases it was still possible for an attacker to 754838032Speter insert newlines into a queue file, thus allowing access to 754938032Speter any user (except root). 755038032Speter CONFIG: no changes -- it is not a bug that the configuration 755138032Speter version number is unchanged. 755238032Speter 755364562Sgshapiro8.7.3/8.7.3 1995/12/03 755438032Speter Fix botch in name server timeout in RCPT code; this problem caused 755538032Speter two responses in SMTP, which breaks things horribly. Fix 755638032Speter from Gregory Neil Shapiro of WPI. 755738032Speter Verify that L= value on M lines cannot be negative, which could cause 755838032Speter negative array subscripting. Not a security problem since 755938032Speter this has to be in the config file, but it could have caused 756038032Speter core dumps. Pointed out by Bryan Costales. 756138032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 756238032Speter Costales. 756338032Speter PORTABILITY FIXES: 756438032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 756538032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 756638032Speter order. Tweak it to work properly. Based on fixes 756738032Speter from Fletcher Mattox of UTexas and Betty Lee of 756838032Speter Stanford University. 756938032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 757038032Speter Deficiency pointed out by Bryan Costales of ICSI. 757138032Speter 757264562Sgshapiro8.7.2/8.7.2 1995/11/19 757338032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 757438032Speter OperatorChars, and UnixFromLine options. They were not 757538032Speter properly repaired in 8.7.1. 757638032Speter Completely delete the Bcc: header if and only if there are other 757738032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 757838032Speter last being a historic botch, of course). If Bcc: is the 757938032Speter only recipient header in the message, its value is tossed, 758043730Speter but the header name is kept. The old behavior (always keep 758138032Speter the header name and toss the value) allowed primary recipients 758238032Speter to see that a Bcc: went to _someone_. 758338032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 758438032Speter sender to <address> using -f'' syslog messages. Suggested 758538032Speter by Kari Hurtta. 758638032Speter If a sequence or switch map lookup entry gets a tempfail but then 758738032Speter continues on to another map type, but the name is not found, 758838032Speter return a temporary failure from the sequence or switch map. 758938032Speter For example, if hosts search ``dns files'' and DNS fails 759038032Speter with a tempfail, the hosts map will go on and search files, 759138032Speter but if it fails the whole thing should be a tempfail, not 759238032Speter a permanent (host unknown) failure, even though that is the 759338032Speter failure in the hosts.files map. This error caused hard 759438032Speter bounces when it should have requeued. 759538032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 759690792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 759738032Speter working properly due to excessive paranoia. Pointed out by 759838032Speter John Hawkinson of Panix. 759938032Speter An SMTP RCPT command referencing a host that gave a nameserver 760038032Speter timeout would return a 451 command (8.6 accepted it and 760143730Speter queued it locally). Revert to the 8.6 behavior in order 760238032Speter to simplify queue management for clustered systems. Suggested 760338032Speter by Gregory Neil Shapiro of WPI. The same problem could break 760438032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 760538032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 760638032Speter Infobiogen. 760738032Speter Fix possible buffer overflow in munchstring(). This was not a security 760838032Speter problem because you couldn't specify any argument to this 760938032Speter without first giving up root privileges, but it is still a 761038032Speter good idea to avoid future problems. Problem noted by John 761138032Speter Hawkinson and Sam Hartman of MIT. 761238032Speter ``452 Out of disk space for temp file'' messages weren't being 761338032Speter printed. Fix from David Perlin of Nanosoft. 761443730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 761538032Speter is not set, since this is required to get the actual DSNs 761638032Speter created. Problem pointed out by John Gardiner Myers of CMU. 761738032Speter Log permission problems that cause .forward and :include: files to 761838032Speter be untrusted or ignored on log level 12 and higher. Suggested 761938032Speter by Randy Martin of Clemson University. 762038032Speter Allow user ids in U= clauses of M lines to have hyphens and 762138032Speter underscores. 762238032Speter Fix overcounting of recipients -- only happened when sending to an 762338032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 762438032Speter of Systems and Computer Technology Corporation. 762538032Speter If a message is sent to an address that fails, the error message that 762638032Speter is returned could show some extraneous "success" information 762738032Speter included even if the user did not request success notification, 762838032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 762938032Speter Config files that had no AliasFile definition were defaulting to 763038032Speter using /etc/aliases; this caused problems with nullclient 763138032Speter configurations. Change it back to the 8.6 semantics of 763238032Speter having no local alias file unless it is declared. Problem 763338032Speter noted by Charles Karney of Princeton University. 763438032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 763538032Speter Costales of ICSI. 763638032Speter Map lookups of class "userdb" maps were always case sensitive; they 763738032Speter should be controlled by the -f flag like other maps. Pointed 763838032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 763938032Speter Fix problem that caused some addresses to be passed through ruleset 5 764038032Speter even when they were tagged as "sticky" by prefixing the 764138032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 764238032Speter Technological University. 764338032Speter When converting a message to Quoted-Printable, prevent any lines with 764438032Speter dots alone on a line by themselves. This is because of the 764538032Speter preponderance of broken mailers that still get this wrong. 764638032Speter Code contributed by Per Hedeland of Ericsson. 764738032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 764838032Speter out by Bjart Kvarme of USIT/UiO (Norway). 764938032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 765038032Speter Requested by Allan Johannesen. 765138032Speter Delete check for text format of alias files -- it should be legal 765238032Speter to have the database format of the alias files without the 765338032Speter text version. Problem pointed out by Joe Rhett of Navigist, 765438032Speter Inc. 765538032Speter If "Ot" was specified with no value, the TZ variable was not properly 765638032Speter imported from the environment. Pointed out by Frank Crawford 765738032Speter <frank@ansto.gov.au>. 765838032Speter Some architectures core dumped on "program" maps that didn't have 765938032Speter extra arguments. Patch from Booker C. Bense of Stanford 766038032Speter University. 766138032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 766238032Speter the parent should do this. Fix from Brian Coan of the 766338032Speter Association for Progressive Communications. 766438032Speter If MinQueueAge was set and a message was considered but not run 766538032Speter during a queue run and the Timeout.queuereturn interval was 766638032Speter reached, a "timed out" error message would be returned that 766738032Speter didn't include the failed address (and claimed to be a warning 766838032Speter even though it was fatal). The fix is to not return such 766938032Speter messages until they are actually tried, i.e., in the next 767038032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 767138032Speter SINTEF RUNIT, Oslo. 767238032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 767338032Speter that have the hes_getmailhost() routine.

Bug 772038032Speter pointed out by John Hawkinson of MIT. 772138032Speter Fix strange case of an executable called by a program map that 772238032Speter returns a value but also a non-zero exit status; this 772338032Speter would give contradictory results in the higher level; in 772438032Speter particular, the default clause in the map lookup would be 772538032Speter ignored. Change to ignore the value if the program returns 772638032Speter non-zero exit status. From Tom Moore of AT&T GIS. 772738032Speter Shorten parameters passed to syslog() in some contexts to avoid a 772838032Speter bug in many vendors' implementations of that routine. Although 772938032Speter this isn't really a bug in sendmail per se, and my solution 773038032Speter has to assume that syslog() has at least a 1K buffer size 773138032Speter internally (I know some vendors have shortened this 773238032Speter dramatically -- they're on their own), sendmail is a popular 773338032Speter target. Also, limit the size of %s arguments in sprintf. 773438032Speter These both have possible security implications. Solutions 773538032Speter suggested by Casper Dik of Sun's Network Security Group 773638032Speter (Holland), Mark Seiden, and others. 773738032Speter Fix a problem that might cause a non-standard -B (body type) 773838032Speter parameter to be passed to the next server with undefined 773938032Speter results. This could have security implications. 774038032Speter If a filesystem was at > 100% utilization, the freediskspace() 774138032Speter routine incorrectly returned an error rather than zero. 774238032Speter Problem noted by G. Paul Ziemba of Alantec. 774338032Speter Change MX sort order so that local hostnames (those in $=w) always 774438032Speter sort first within a given preference. This forces the bestmx 774538032Speter map to always return the local host first, if it is included 774638032Speter in the list of highest priority MX records. From K. Robert 774738032Speter Elz. 774838032Speter Avoid some possible null pointer dereferences. Fixes from Randy 774938032Speter Martin <WOLF@CLEMSON.EDU> 775038032Speter When sendmail starts up on systems that have no fully qualified 775138032Speter domain name (FQDN) anywhere in the first matching host map 775238032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 775338032Speter sendmail would sleep to try to find a FQDN, which it really 775438032Speter really needs. This has been changed to fall through to the 775538032Speter next map type if it can't find a FQDN -- i.e., if the hosts 775638032Speter file doesn't have a FQDN, it will try dns even though the 775738032Speter short name was found in /etc/hosts. This is probably a crock, 775838032Speter but many people have hosts files without FQDNs. Remember: 775938032Speter domain names are your friends. 776038032Speter Log a high-priority message if you can't find your FQDN during startup. 776138032Speter Suggested by Simon Barnes of Schlumberger Limited. 776238032Speter When using Hesiod, initialize it early to improve error reporting. 776338032Speter Patch from Don Lewis of Silicon Systems, Inc. 776438032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 776538032Speter connection timeout in the kernel. Add a new "connect" timeout 776638032Speter to limit this time. Defaults to zero (use whatever the 776738032Speter kernel provides). Based on code contributed by J.R. Oldroyd 776838032Speter of TerraNet. 776938032Speter Under some circumstances, a failed message would not be properly 777038032Speter removed from the queue, causing tons of bogus error messages. 777138032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 777238032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 777338032Speter of WPI. 777438032Speter PORTABILITY FIXES: 777538032Speter On IRIX 5.x, there was an inconsistency in the setting 777638032Speter of sendmail.st location. Change the Makefile to 777738032Speter install it in /var/sendmail.st to match the OSTYPE 777838032Speter file and SGI standards.

Suggested by Per Hedeland of Ericsson. 779238032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 779338032Speter otherwise the F=S causes the From_ line to imply that root is 779438032Speter the sender. Problem pointed out by Claude Scarpelli of 779538032Speter Infobiogen (France). 779638032Speter NEW FILES: 779738032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 779838032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 779938032Speter src/Makefiles/Makefile.UXPDS 780038032Speter 780164562Sgshapiro8.7/8.7 1995/09/16 780238032Speter Fix a problem that could cause sendmail to run out of file 780338032Speter descriptors due to a trashed data structure after a 780438032Speter vfork.

This was used "safely" in the sense 781038032Speter that it only did a stat, but it would have set the 781138032Speter map modification time improperly. Problem pointed out 781238032Speter by Roy Mongiovi of Georgia Tech. 781338032Speter Clean up the Subject: line on warning messages and return 781438032Speter receipts so that they don't say "Returned mail:"; this 781538032Speter can be confusing. 781638032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 781738032Speter useful enough to make it worthwhile printing on "-d". 781838032Speter Avoid logging alias statistics every time you read the alias 781938032Speter file on systems with no database method compiled in. 782038032Speter If you have a name with a trailing dot, and you try looking it 782138032Speter up using gethostbyname without the dot (for /etc/hosts 782238032Speter compatibility), be sure to turn off RES_DEFNAMES and 782338032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 782438032Speter Problem noted by Charles Amos of the University of 782538032Speter Maryland. 782638032Speter Don't do timeouts in collect if you are not running SMTP. 782738032Speter There is nothing that says you can't have a long 782838032Speter running program piped into sendmail (possibly via 782938032Speter /bin/mail, which just execs sendmail). Problem reported 783038032Speter by Don "Truck" Lewis of Silicon Systems. 783138032Speter Try gethostbyname() even if the DNS lookup fails iff option I 783238032Speter is not set. This allows you to have hosts listed in 783338032Speter NIS or /etc/hosts that are not known to DNS. It's normally 783438032Speter a bad idea, but can be useful on firewall machines. This 783538032Speter should really be broken out on a separate flag, I suppose. 783638032Speter Avoid compile warnings against BIND 4.9.3, which uses function 783738032Speter prototypes.

From Kyle Jones of UUNET. 784238032Speter SECURITY: avoid denial-of-service attacks possible by destroying 784338032Speter the alias database file by setting resource limits low. 784438032Speter This involves adding two new compile-time options: 784538032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 784638032Speter available) and HASULIMIT (indicating that ulimit(2) support 784738032Speter is available -- the Release 3 form is used). The former 784838032Speter is assumed on BSD-based systems, the latter on System 784938032Speter V-based systems. Attack noted by Phil Brandenberger of 785038032Speter Swarthmore University. 785138032Speter New syntaxes in test (-bt) mode: 785238032Speter ``.Dmvalue'' will define macro "m" to "value". 785338032Speter ``.Ccvalue'' will add "value" to class "c". 785438032Speter ``=Sruleset'' will dump the contents of the indicated 785538032Speter ruleset. 785638032Speter ``=M'' will display the known mailers. 785738032Speter ``-ddebug-spec'' is equivalent to the command-line 785838032Speter -d debug flag. 785938032Speter ``$m'' will print the value of macro $m. 786038032Speter ``$=c'' will print the contents of class $=c. 786138032Speter ``/mx host'' returns the MX records for ``host''. 786238032Speter ``/parse address'' will parse address, returning the value of 786338032Speter crackaddr (essentially, the comment information) 786438032Speter and the parsed address. 786538032Speter ``/try mailer address'' will rewrite address into the form 786638032Speter it will have when presented to the indicated mailer. 786738032Speter ``/tryflags flags'' will set flags used by parsing. The 786838032Speter flags can be `H' for header or `E' for envelope, 786938032Speter and `S' for sender or `R' for recipient. These 787038032Speter can be combined, so `HR' sets flags for header 787138032Speter recipients. 787238032Speter ``/canon hostname'' will try to canonify hostname and 787338032Speter return the result. 787438032Speter ``/map mapname key'' will look up `key' in the indicated 787538032Speter `mapname' and return the result. 787638032Speter Somewhat better handling of UNIX-domain socket addresses -- it 787738032Speter should show the pathname rather than hex bytes. 787838032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 787938032Speter the header for envelope sender information and uses 788038032Speter CR-LF as message terminators. It was thought to be 788138032Speter obsolete (used only for Arpanet NCP protocols), but it 788238032Speter turns out that the UK ``Grey Book'' protocols require 788338032Speter that functionality. 788438032Speter Fix a fix in previous release -- if gethostname and gethostbyname 788538032Speter return a name without dots, and if an attempt to canonify 788638032Speter that name fails, wait one minute and try again. This can 788738032Speter result in an extra 60 second delay on startup if your system 788838032Speter hostname (as returned by hostname(1)) has no dot and no names 788938032Speter listed in /etc/hosts or your NIS map have a dot. 789038032Speter Check for proper domain name on HELO and EHLO commands per 789138032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 789238032Speter of Michigan Technological University. 789338032Speter Relax chownsafe rules slightly -- old version said that if you 789438032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 789538032Speter if fpathconf returned EINVAL or ENOSYS), assume that 789638032Speter chown is not safe. The new version falls back to whether 789738032Speter you are on a BSD system or not. This is important for 789838032Speter SunOS, which apparently always returns one of those 789938032Speter error codes. This impacts whether you can mail to files 790038032Speter or not. 790138032Speter Syntax errors such as unbalanced parentheses in the configuration 790238032Speter file could be omitted if you had "Oem" prior to the 790338032Speter syntax error in the config file. Change to always print 790438032Speter the error message. It was especially weird because it 790538032Speter would cause a "warning" message to be sent to the Postmaster 790638032Speter for every message sent (but with no transcript). Problem 790738032Speter noted by Gregory Paris of Motorola. 790838032Speter Rewrite collect and putbody to handle full 8-bit data, including 790938032Speter zero bytes.

This is to handle the 797838032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 797938032Speter assume that ``group name:'' is a comment on the first 798038032Speter address and the ``;'' is a comment on the last address). 798138032Speter This requires config file support to get right. It does 798238032Speter understand that :: is NOT this syntax, and can be turned 798338032Speter off completely by setting the ColonOkInAddresses option. 798438032Speter Level 6 config files added with new mailer flags: 798538032Speter A Addresses are aliasable. 798638032Speter i Do udb rewriting on envelope as well as header 798738032Speter sender lines. Applies to the from address mailer 798838032Speter flags rather than the recipient mailer flags. 798938032Speter j Do udb rewriting on header recipient addresses. 799038032Speter Applies to the sender mailer flags rather than the 799138032Speter recipient mailer flags. 799238032Speter k Disable check for loops when doing HELO command. 799338032Speter o Always run as the mail recipient, even on local 799438032Speter delivery. 799538032Speter w Check for an /etc/passwd entry for this user. 799638032Speter 5 Pass addresses through ruleset 5. 799738032Speter : Check for :include: on this address. 799838032Speter | Check for |program on this address. 799938032Speter / Check for /file on this address. 800038032Speter @ Look up sender header addresses in the user 800138032Speter database. Applies to the mailer flags for the 800238032Speter mailer corresponding to the envelope sender 800338032Speter address, rather than to recipient mailer flags. 800438032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 800538032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 800638032Speter mailers, and the ColonOkInAddresses option. 800738032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 800838032Speter John Beck of Hewlett-Packard, who generously contributed 800938032Speter their implementation to me, which I then didn't use (see 801038032Speter mime.c for an explanation of why). This adds the 801138032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 801238032Speter to control handling of 8-bit data. These have to cope with 801338032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 801438032Speter 8-bit data that is entered without declaring it as 8-bit 801538032Speter MIME -- technically this is illegal according to the 801638032Speter specs) and labelled 8-bit data (that is, it was declared 801738032Speter as 8BITMIME in the ESMTP session or by using the 801838032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 801938032Speter set then 8-bit data is sent to non-8BITMIME machines 802038032Speter instead of converting to 7 bit (essentially using 802138032Speter just-send-8 semantics). The values for EightBitMode are: 802238032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 802338032Speter any necessary conversion of 8BITMIME to 7BIT 802438032Speter (essentially, the full MIME option). 802538032Speter p pass unlabelled 8-bit input, but convert labelled 802638032Speter 8BITMIME input to 7BIT as required (default). 802738032Speter s strict adherence: reject unlabelled 8-bit input, 802838032Speter convert 8BITMIME to 7BIT as required. The F=8 802938032Speter flag is ignored. 803038032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 803138032Speter the setting of F=8. 803238032Speter Add new internal class 'n', which is the set of MIME Content-Types 803338032Speter which can not be 8 to 7 bit encoded because of other 803438032Speter considerations. Types "multipart/*" and "message/*" are 803538032Speter never directly encoded (although their components can be). 803638032Speter Add new internal class 's', which is the set of subtypes of the 803738032Speter MIME message/* content type that can be treated as though 803838032Speter they are an RFC822 message. It is predefined to have 803938032Speter "rfc822". Suggested By Kari Hurtta. 804038032Speter Add new internal class 'e'. This is the set of MIME 804138032Speter Content-Transfer-Encodings that can be converted to 804238032Speter a seven bit format (Quoted-Printable or Base64). It is 804338032Speter preinitialized to contain "7bit", "8bit", and "binary". 804438032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 804538032Speter short name) to set the default character set to use in the 804638032Speter Content-Type: header when doing encoding of an 8-bit message 804738032Speter which isn't marked as MIME into MIME format. If the C= 804838032Speter parameter is set on the Envelope From address, use that as 804938032Speter the default encoding; else use the DefaultCharSet option. 805038032Speter If neither is set, it defaults to "unknown-8bit" as 805138032Speter suggested by RFC 1428 section 3. 805238032Speter Allow ``U=user:group'' field in mailer definition to set a default 805338032Speter user and group that a mailer will be executed as. This 805438032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 805538032Speter also set, it is the uid/gid that will always be used (that 805638032Speter is, the controlling address is ignored). The values may be 805738032Speter numeric or symbolic; if only a symbolic user is given (no 805838032Speter group) that user's default group in the passwd file is used 805938032Speter as the group. Based on code donated by Chip Rosenthal of 806038032Speter Unicom. 806138032Speter Allow `u' option to also accept user:group as a value, in the same 806238032Speter fashion as the U= mailer option. 806338032Speter Add the symbolic time zone name in the Arpanet format dates (as 806438032Speter a comment). This adds a new compile-time configuration 806538032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 806638032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 806738032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 806838032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 806938032Speter timezone()), or TZ_NONE (don't include the comment). Code 807038032Speter from Chip Rosenthal. 807138032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 807238032Speter For example, 807338032Speter O Timeout.helo = 2m 807438032Speter There are also two new suboptions "queuereturn" and 807538032Speter "queuewarn"; these subsume the old T option. Thus, to 807638032Speter set them both the preferred new syntax is 807738032Speter O Timeout.queuereturn = 5d 807838032Speter O Timeout.queuewarn = 4h 807938032Speter Sort queue by host name instead of by message priority if the 808038032Speter QueueSortOrder option (no short name) is set is set to 808138032Speter ``host''. This makes better use of the connection cache, 808238032Speter but may delay more ``interactive'' messages behind large 808338032Speter backlogs under some circumstances. This is probably a 808438032Speter good option if you have high speed links or don't do lots 808538032Speter of ``batch'' messages, but less good if you are using 808638032Speter something like PPP on a 14.4 modem. Based on code 808738032Speter contributed by Roy Mongiovi of Georgia Tech (my main 808838032Speter contribution was to make it configurable). 808938032Speter Save i-number of df file in qf file to simplify rebuilding of queue 809038032Speter after disastrous disk crash. Suggested by Kyle Jones of 809138032Speter UUNET; closely based on code from KJS DECWRL code written 809238032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 809338032Speter are NOT back compatible with 8.6 -- that is, you can convert 809438032Speter from 8.6 to 8.7, but not the other direction. 809538032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 809638032Speter route-addrs in envelopes; this is because in some cases 809738032Speter they can be sent to the shell, which interprets them as 809838032Speter I/O redirection. 809938032Speter Don't include error file (option E) with return-receipts; this 810038032Speter can be confusing. 810138032Speter Don't send "Warning: cannot send" messages to owner-* or 810238032Speter *-request addresses. Suggested by Christophe Wolfhugel 810338032Speter of the Institut Pasteur, Paris. 810438032Speter Allow -O command line flag to set long form options. 810538032Speter Add "MinQueueAge" option to set the minimum time between attempts 810638032Speter to run the queue. For example, if the queue interval 810738032Speter (-q value) is five minutes, but the minimum queue age 810838032Speter is fifteen minutes, jobs won't be tried more often than 810938032Speter once every fifteen minutes. This can be used to give 811038032Speter you more responsiveness if your delivery mode is set to 811138032Speter queue-only. 811238032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 811338032Speter :include: and .forward files. 811438032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 811538032Speter key field name, the value field name, and the field 811638032Speter delimiter. The field delimiter can be a single character 811738032Speter or the sequence "\t" or "\n" for tab or newline. 811838032Speter These are for use by NIS+ and similar access methods. 811938032Speter Change maps to always strip quotes before lookups; the -q flag 812043730Speter turns off this behavior. Suggested by Motonori Nakamura. 812138032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 812238032Speter key and value field names respectively. Code donated by 812338032Speter Sun Microsystems. 812438032Speter Add "hesiod" map class. The "file name" is used as the 812538032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 812638032Speter first value found for the match. Code donated by Scott 812738032Speter Hutton of Indiana University. 812838032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 812938032Speter specify the name of the property that is searched as the 813038032Speter key and a -v flag to specify the name of the property that 813138032Speter is returned as the value (defaults to "members"). The 813238032Speter default map is "/aliases". Some code based on code 813338032Speter contributed by Robert La Ferla of Hot Software. 813438032Speter Add "text" map class. This does slow, linear searches through 813538032Speter text files. The -z flag specifies a column delimiter 813638032Speter (defaults to any sequence of white space), the -k flag 813738032Speter sets the key column number, and the -v flag sets the 813838032Speter value column number. Lines beginning with `#' are treated 813938032Speter as comments. 814038032Speter Add "program" map class to execute arbitrary programs. The search 814138032Speter key is presented as the last argument; the output is one 814238032Speter line read from the programs standard output. Exit statuses 814338032Speter are from sysexits.h. 814438032Speter Add "sequence" map class -- searches maps in sequence until it 814538032Speter finds a match. For example, the declarations: 814638032Speter Kmap1 ... 814738032Speter Kmap2 ... 814838032Speter Kmapseq sequence map1 map2 814938032Speter defines a map "mapseq" that first searches map1; if the 815038032Speter value is found it is returned immediately, otherwise 815138032Speter map2 is searched and the value returned. 815238032Speter Add "switch" map class. This is much like "sequence" except that 815338032Speter the ordering is fetched from an external file, usually 815438032Speter the system service switch. The parameter is the name of 815538032Speter the service to switch on, and the maps that it will use 815638032Speter are the name of the switch map followed by ".service_type". 815738032Speter For example, if the declaration of the map is 815838032Speter Ksample switch hosts 815938032Speter and the system service switch specifies that hosts are 816038032Speter looked up using dns and nis in that order, then this is 816138032Speter equivalent to 816238032Speter Ksample sequence sample.dns sample.nis 816338032Speter The subordinate maps (sample.*) must already be defined. 816438032Speter Add "user" map class -- looks up users using getpwnam. Takes a 816538032Speter "-v field" flag on the definition that tells what passwd 816638032Speter entry to return -- legal values are name, passwd, uid, gid, 816738032Speter gecos, dir, and shell. Generally expected to be used with 816838032Speter the -m (matchonly) flag. 816938032Speter Add "bestmx" map class -- returns the best MX value for the host 817038032Speter listed as the value. If there are several "best" MX records 817138032Speter for this host, one will be chosen at random. 817238032Speter Add "userdb" map class -- looks up entries in the user database. 817338032Speter The "file name" is actually the tag that will be used, 817438032Speter typically "mailname". If there are multiple entries 817538032Speter matching the name, the one chosen is undefined. 817638032Speter Add multiple queue timeouts (both return and warning). These are 817738032Speter set by the Precedence: or Priority: header fields to one of 817838032Speter three values. If a Priority: is set and has value "normal", 817964562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 818038032Speter used. If no priority is set, the Precedence: is consulted; 818138032Speter if negative, non-urgent timeouts are used; if greater than 818238032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 818338032Speter are used. The timeouts are set by setting the six timeouts 818438032Speter queue{warn,return}.{urgent,normal,non-urgent}. 818538032Speter Fix problem when a mail address is resolved to a $#error mailer 818638032Speter with a temporary failure indication; it works in SMTP, 818738032Speter but when delivering locally the mail is silently discarded. 818838032Speter This patch, from Kyle Jones of UUNET, bounces it instead 818938032Speter of queueing it (queueing is very hard). 819038032Speter When using /etc/hosts or NIS-style lookups, don't assume that 819138032Speter the first name in the list is the best one -- instead, 819238032Speter search for the first one with a dot. For example, if 819338032Speter an /etc/hosts entry reads 819438032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 819538032Speter this change will use the second name as the canonical 819638032Speter machine name instead of the initial, unqualified name. 819738032Speter Change dequote map to replace spaces in quoted text with a value 819838032Speter indicated by the -s flag on the dequote map definition. 819938032Speter For example, ``Mdequote dequote -s_'' will change 820038032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 820138032Speter quoted (because of the space character). Suggested by Dan 820238032Speter Oscarsson for use in X.400 addresses. 820338032Speter Implement long macro names as ${name}; long class names can 820438032Speter be similarly referenced as $={name} and $~{name}. 820538032Speter Definitions are (e.g.) ``D{name}value''. Names that have 820638032Speter a leading lower case letter or punctuation characters are 820738032Speter reserved for internal use by sendmail; i.e., config files 820838032Speter should use names that begin with a capital letter. Based 820938032Speter on code contributed by Dan Oscarsson. 821038032Speter Fix core dump if getgrgid returns a null group list (as opposed 821138032Speter to an empty group list, that is, a pointer to a list 821238032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 821338032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 821438032Speter failed, it called syserr which called newstr which called 821538032Speter xalloc.... The newstr is now avoided for "panic" messages. 821638032Speter Reported by Stuart Kemp of James Cook University. 821738032Speter Improve connection cache timeouts; previously, they were not even 821838032Speter checked if you were delivering to anything other than an 821938032Speter IPC-connected host, so a series of (say) local mail 822038032Speter deliveries could cause cached connections to be open 822138032Speter much longer than the specified timeout. 822238032Speter If an incoming message exceeds the maximum message size, stop 822338032Speter writing the incoming bytes to the queue data file, since 822438032Speter this can fill your mqueue partition -- this is a possible 822538032Speter denial-of-service attack. 822638032Speter Don't reject all numeric local user names unless HESIOD is 822738032Speter defined. It turns out that Posix allows all-numeric 822838032Speter user names. Fix from Tony Sanders of BSDI. 822938032Speter Add service switch support. If the local OS has a service 823038032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 823138032Speter on DEC systems) that will be used; otherwise, it falls back 823238032Speter to using a local mechanism based on the ServiceSwitchFile 823338032Speter option (default: /etc/service.switch). For example, if the 823438032Speter service switch lists "files" and "nis" for the aliases 823538032Speter service, that will be the default lookup order. the "files" 823638032Speter ("local" on DEC) service type expands to any alias files 823738032Speter you listed in the configuration file, even if they aren't 823838032Speter actually file lookups. 823938032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 824038032Speter variable which tells whether or not DNS should be considered 824138032Speter canonical. This is now determined based on whether or not 824238032Speter "dns" is in the service list for "hosts". 824338032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 824438032Speter Status Notifications). DSN notifications override 824538032Speter Return-Receipt-To: headers, which are bogus anyhow -- 824638032Speter support for them has been removed. 824738032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 824838032Speter definitions to define the types used in DSN returns for 824938032Speter MTA names, addresses, and diagnostics respectively. 825038032Speter Extend heuristic to force running in ESMTP mode to look for the 825138032Speter five-character string "ESMTP" anywhere in the 220 greeting 825238032Speter message (not just the second line). This is to provide 825338032Speter better compatibility with other ESMTP servers. 825438032Speter Print sequence number of job when running the queue so you can 825538032Speter easily see how much progress you have made. Suggested 825638032Speter by Peter Wemm of DIALix. 825738032Speter Map newlines to spaces in logged message-ids; some versions of 825838032Speter syslog truncate the rest of the line after newlines. 825938032Speter Suggested by Fletcher Mattox of U. Texas. 826038032Speter Move up forking for job runs so that if a message is split into 826138032Speter multiple envelopes you don't get "fork storms" -- this 826238032Speter also improves the connection cache utilization. 826338032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 826438032Speter the purposes of refusing to send error returns. Suggested 826538032Speter by Motonori Nakamura of Ritsumeikan University. 826638032Speter Relax rules on when a file can be written when referenced from 826738032Speter the aliases file: use the default uid/gid instead of the 826838032Speter real uid/gid. This allows you to create a file owned by 826938032Speter and writable only by the default uid/gid that will work 827090792Sgshapiro all the time (without having the set-user-ID bit set). Change 827138032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 827238032Speter Microsystems. 827338032Speter Add "DialDelay" option (no short name) to provide an "extra" 827438032Speter delay for dial on demand systems. If this is non-zero 827538032Speter and a connect fails, sendmail will wait this long and 827638032Speter then try again. If it takes longer than the kernel 827738032Speter timeout interval to establish the connection, this 827838032Speter option can give the network software time to establish 827938032Speter the link. The default units are seconds. 828038032Speter Move logging of sender information to be as early as possible; 828138032Speter previously, it could be delayed a while for SMTP mail 828238032Speter sent to aliases. Suggested by Brad Knowles of the 828338032Speter Defense Information Systems Agency. 828438032Speter Call res_init() before setting RES_DEBUG; this is required by 828538032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 828638032Speter the National Computer Security Center. 828738032Speter Add xdelay= field in logs -- this is a transaction delay, telling 828838032Speter you how long it took to deliver to this address on the 828938032Speter last try. It is intended to be used for sorting mailing 829038032Speter lists to favor "quick" addresses. Provided for use by 829138032Speter the mailprio scripts (see below). 829238032Speter If a map cannot be opened, and that map is non-optional, and 829338032Speter an address requires that map for resolution, queue the 829438032Speter map instead of bouncing it. This involves creating a 829538032Speter pseudo-class of maps called "bogus-map" -- if a required 829638032Speter map cannot be opened, the class is changed to bogus-map; 829738032Speter all queries against bogus-map return "tempfail". The 829838032Speter bogus-map class is not directly accessible. A sample 829938032Speter implementation was donated by Jem Taylor of Glasgow 830038032Speter University Computing Service. 830138032Speter Fix a possible core dump when mailing to a program that talks 830238032Speter SMTP on its standard input. Fix from Keith Moore of 830338032Speter the University of Kentucky. 830438032Speter Make it possible to resolve filenames to $#local $: @ /filename; 830538032Speter previously, the "@" would cause it to not be recognized 830638032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 830738032Speter Accept a -1 signal to re-exec the daemon. This only works if 830838032Speter argv[0] is a full path to sendmail. 830938032Speter Fix bug in "addr=..." field in O option on little-endian machines 831038032Speter -- the network number wasn't being converted to network 831138032Speter byte order. Patch from Kurt Lidl of Pix Technologies 831238032Speter Corporation. 831338032Speter Pre-initialize the resolver early on; this is to avoid a bug with 831438032Speter BIND 4.9.3 that can cause the _res.retry field to get 831538032Speter reset to zero, causing all name server lookups to time 831638032Speter out. Fix from Matt Day of Artisoft. 831738032Speter Restore T line (trusted users) in config file -- but instead of 831838032Speter locking out the -f flag, they just tell whether or not 831938032Speter an X-Authentication-Warning: will be added. This really 832038032Speter just creates new entries in class 't', so "Ft/file/name" 832138032Speter can be used to read trusted user names from a file. 832238032Speter Trusted users are also allowed to execute programs even 832338032Speter if they have a shell that isn't in /etc/shells. 832438032Speter Improve NEWDB alias file rebuilding so it will create them 832538032Speter properly if they do not already exist. This had been 832638032Speter a MAYBENEXTRELEASE feature in 8.6.9. 832738032Speter Check for @:@ entry in NIS maps before starting up to avoid 832838032Speter (but not prevent, sigh) race conditions. This ought to 832938032Speter be handled properly in ypserv, but isn't. Suggested by 833038032Speter Michael Beirne of Motorola. 833138032Speter Refuse connections if there isn't enough space on the filesystem 833238032Speter holding the queue. Contributed by Robert Dana of Wolf 833338032Speter Communications. 833438032Speter Skip checking for directory permissions in the path to a file 833538032Speter when checking for file permissions iff setreuid() 833638032Speter succeeded -- it is unnecessary in that case. This avoids 833738032Speter significant performance problems when looking for .forward 833838032Speter files. Based on a suggestion by Win Bent of USC. 833938032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 834038032Speter arbitrary ruleset number assigned or "Sname = integer" 834138032Speter to assign a specific ruleset number. Reference is 834238032Speter $>name_or_number. Names can be composed of alphas, digits, 834338032Speter underscore, or hyphen (first character must be non-numeric). 834438032Speter Allow -o flag on AliasFile lines to make the alias file optional. 834538032Speter From Bryan Costales of ICSI. 834638032Speter Add NoRecipientAction option to handle the case where there is 834738032Speter no legal recipient header in the message. It can take 834838032Speter on values: 834938032Speter None Leave the message as is. The 835038032Speter message will be passed on even 835138032Speter though it is in technically 835238032Speter illegal syntax. 835338032Speter Add-To Add a To: header with any 835438032Speter recipients that it can find from 835538032Speter the envelope. This risks exposing 835638032Speter Bcc: recipients. 835738032Speter Add-Apparently-To Add an Apparently-To: header. This 835838032Speter has almost no redeeming social value, 835938032Speter and is provided only for back 836038032Speter compatibility. 836138032Speter Add-To-Undisclosed Add a header reading 836238032Speter To: undisclosed-recipients:; 836338032Speter which will have the effect of 836438032Speter making the message legal without 836538032Speter exposing Bcc: recipients. 836638032Speter Add-Bcc To add an empty Bcc: header. 836738032Speter There is a chance that mailers down 836838032Speter the line will delete this header, 836938032Speter which could cause exposure of Bcc: 837038032Speter recipients. 837138032Speter The default is NoRecipientAction=None. 837238032Speter Truncate (rather than delete) Bcc: lines in the header. This 837338032Speter should prevent later sendmails (at least, those that don't 837438032Speter themselves delete Bcc:) from considering this message to 837538032Speter be non-conforming -- although it does imply that non-blind 837638032Speter recipients can see that a Bcc: was sent, albeit not to whom. 837738032Speter Add SafeFileEnvironment option. If declared, files named as delivery 837838032Speter targets must be regular files in addition to the regular 837938032Speter checks. Also, if the option is non-null then it is used as 838038032Speter the name of a directory that is used as a chroot(2) 838138032Speter environment for the delivery; the file names listed in an 838238032Speter alias or forward should include the name of this root. 838338032Speter For example, if you run with 838438032Speter O SafeFileEnvironment=/arch 838538032Speter then aliases should reference "/arch/rest/of/path". If a 838638032Speter value is given, sendmail also won't try to save to 838738032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 838838032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 838938032Speter Support -A flag for alias files; this will comma concatenate like 839038032Speter entries. For example, given the aliases: 839138032Speter list: member1 839238032Speter list: member2 839338032Speter and an alias file declared as: 839438032Speter OAhash:-A /etc/aliases 839538032Speter the final alias inserted will be "list: member1,member2"; 839638032Speter without -A you will get an error on the second and subsequent 839738032Speter alias for "list". Contributed by Bryan Costales of ICSI. 839838032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 839938032Speter Fix a problem that could cause very long addresses to core dump in 840038032Speter some special circumstances. Problem pointed out by Allan 840138032Speter Johannesen. 840238032Speter (Internal change.) Change interface to expand() (macro expansion) 840338032Speter to be simpler and more consistent. 840438032Speter Delete check for funny qf file names. This didn't really give 840538032Speter any extra security and caused some people some problems. 840638032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 840738032Speter at compile time.) Suggested by Kyle Jones of UUNET. 840838032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 840938032Speter merge with DSN code; this is simpler and more consistent. 841038032Speter This may affect some people who have written their own 841138032Speter checkcompat() routine. 841238032Speter (Internal change.) Eliminate `D' line in qf file. The df file 841338032Speter is now assumed to be the same name as the qf file (with 841438032Speter the `q' changed to a `d', of course). 841538032Speter Avoid forking for delivery if all recipient mailers are marked as 841638032Speter "expensive" -- this can be a major cost on some systems. 841738032Speter Essentially, this forces sendmail into "queue only" mode 841838032Speter if all it is going to do is queue anyway. 841938032Speter Avoid sending a null message in some rather unusual circumstances 842038032Speter (specifically, the RCPT command returns a temporary 842138032Speter failure but the connection is lost before the DATA 842238032Speter command). Fix from Scott Hammond of Secure Computing 842338032Speter Corporation. 842438032Speter Change makesendmail to use a somewhat more rational naming scheme: 842538032Speter Makefiles and obj directories are named $os.$rel.$arch, 842638032Speter where $os is the operating system (e.g., SunOS), $rel is 842738032Speter the release number (e.g., 5.3), and $arch is the machine 842838032Speter architecture (e.g., sun4). Any of these can be omitted, 842938032Speter and anything after the first dot in a release number can 843038032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 843138032Speter version used $os.$arch.$rel and was rather less general. 843238032Speter Change makesendmail to do a "make depend" in the target directory 843338032Speter when it is being created. This involves adding an empty 843438032Speter "depend:" entry in most Makefiles. 843538032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 843638032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 843738032Speter of the Finnish Meteorological Institute. 843838032Speter Fix problem that could cause multiple responses to DATA command 843938032Speter on header syntax errors (e.g., lines beginning with colons). 844038032Speter Problem noted by Jens Thomassen of the University of Oslo. 844138032Speter Don't let null bytes in headers cause truncation of the rest of 844238032Speter the header. 844338032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 844438032Speter Increase timeouts on message data puts to allow time for receivers 844538032Speter to canonify addresses in headers on the fly. This is still 844638032Speter a rather ugly heuristic. From Motonori Nakamura. 844738032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 844838032Speter records are not used when canonifying names, and when MX 844938032Speter lookups are done for addressing they must be fully 845038032Speter qualified. This is useful if you have a wildcard MX record, 845138032Speter although it may cause other problems. In general, don't use 845238032Speter wildcard MX records. Patch from Motonori Nakamura. 845338032Speter Eliminate default two-line SMTP greeting message. Instead of 845438032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 845538032Speter is added between the first and second word of the first 845638032Speter line of the greeting message (i.e., immediately after the 845738032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 845838032Speter compile flag. Old sendmails won't see the ESMTP, but that's 845938032Speter acceptable because SIZE was the only useful extension that 846038032Speter old sendmails understand. 846138032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 846238032Speter invoked state dumps. From Masaharu Onishi. 846338032Speter Allow on-line comments in .forward and :include: files; they are 846438032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 846538032Speter is a space or a tab. This is intended for native 846638032Speter representation of non-ASCII sets such as Japanese, where 846738032Speter existing encodings would be unreadable or would lose 846838032Speter data -- for example, 846938032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 847038032Speter (romanized/less information) 847138032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 847238032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 847338032Speter (with MIME encoding, not human readable) 847438032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 847538032Speter (native encoding with ISO-2022-JP) 847638032Speter The last form is human readable in the Japanese environment. 847738032Speter Based on a fix from (surprise!) Motonori Nakamura. 847838032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 847938032Speter messages to that host; these are most frequently associated 848038032Speter with addresses rather than the host, with the exception of 848138032Speter 421 (service shutting down). The effect was to cause queues 848238032Speter to sometimes take an excessive time to flush. Reported by 848338032Speter Robert Sargent of Southern Geographics Technologies and 848438032Speter Eric Prestemon of American University. 848538032Speter Add Nice=N mailer option to set the niceness at which a mailer will 848638032Speter run. This is actually a relative niceness (that is, an 848738032Speter increment on the background value). 848838032Speter Log queue runs that are skipped due to high loads. They are logged 848938032Speter at LOG_INFO priority iff the log level is > 8. Contributed 849038032Speter by Bruce Nagel of Data General. 849138032Speter Allow the error mailer to accept a DSN-style error status code 849238032Speter instead of an sysexits status code in the host part. 849338032Speter Anything with a dot will be interpreted as a DSN-style code. 849438032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 849538032Speter to encode characters that might be munged by an EBCDIC system 849638032Speter in addition to the set required by RFC 1521. The additional 849738032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 849838032Speter (Think of "IBM 360" as the mnemonic for this flag.) 849938032Speter Change check for mailing to files to look for a pathname of [FILE] 850038032Speter rather than looking for the mailer named *file*. The mapping 850138032Speter of leading slashes still goes to the *file* mailer. This 850238032Speter allows you to implement the *file* mailer as a separate 850338032Speter program, for example, to insert a Content-Length: header 850438032Speter or do special security policy. However, note that the usual 850538032Speter initial checking for the file permissions is still done, and 850638032Speter the program in question needs to be very careful about how 850738032Speter it does the file write to avoid security problems. 850838032Speter Be able to read ~root/.forward even if the path isn't accessible to 850938032Speter regular users. This is disrecommended because sendmail 851038032Speter sometimes does not run as root (e.g., when an unsafe option 851138032Speter is specified on the command line), but should otherwise be 851238032Speter safe because .forward files must be owned by the user for 851338032Speter whom mail is being forwarded, and cannot be a symbolic link. 851438032Speter Suggested by Forrest Aldrich of Wang Laboratories. 851538032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 851638032Speter file. This is used for canonifying hostnames when the 851738032Speter service type is "files". 851838032Speter Implement programs on F (read class from file) line. The syntax is 851938032Speter Fc|/path/to/program to read the output from the program 852038032Speter into class "c". 852138032Speter Probe the network interfaces to find alternate names for this 852238032Speter host. Requires the SIOCGIFCONF ioctl call. Code 852338032Speter contributed by SunSoft. 852438032Speter Add "E" configuration line to set or propagate environment 852538032Speter variables into children. "E<envar>" will propagate 852638032Speter the named variable from the environment when sendmail 852738032Speter was invoked into any children it calls; "E<envar>=<value>" 852838032Speter sets the named variable to the indicated value. Any 852938032Speter variables not explicitly named will not be in the child 853038032Speter environment. However, sendmail still forces an 853138032Speter "AGENT=sendmail" environment variable, in part to enforce 853238032Speter at least one environment variable, since many programs and 853338032Speter libraries die horribly if this is not guaranteed. 853438032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 853538032Speter alias databases -- new algorithm looks for the substring 853638032Speter "/yp/" in the file name. This is more portable and involves 853738032Speter less overhead. Suggested by Motonori Nakamura. 853838032Speter Dynamically allocate the queue work list so that you don't lose 853938032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 854038032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 854138032Speter should not need to be changed) and the MaxQueueRunSize option, 854238032Speter which is the absolute maximum number of jobs that will ever 854338032Speter be handled in a single queue run. Based on code contributed 854438032Speter by Brian Coan of the Institute for Global Communications. 854538032Speter Log message when a message is dropped because it exceeds the maximum 854638032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 854738032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 854838032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 854938032Speter of Mark G. Thomas Consulting. 855038032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 855138032Speter OS-dependent defines). The old semantic of -d0.1 to not 855238032Speter run the daemon in background has been moved to -d99.100, 855338032Speter and the old 52.5 flag (to avoid disconnect() from closing 855438032Speter all output files) has been moved to 52.100. This makes 855538032Speter things more consistent (flags below .100 don't change 855638032Speter semantics) and separates out the backgrounding so that 855738032Speter it doesn't happen automatically on other unrelated debugging 855838032Speter flags. 855938032Speter If -t is used but no addresses are found in the header, give an 856038032Speter error message rather than just doing nothing. Fix from 856138032Speter Motonori Nakamura. 856238032Speter On systems (like SunOS) where the effective gid is not necessarily 856338032Speter included in the group list returned by getgroups(), the 856438032Speter `restrictmailq' option could sometimes cause an authorized 856538032Speter user to not be able to use `mailq'. Fix from Charles Hannum 856638032Speter of MIT. 856738032Speter Allow symbolic service names for [IPC] mailers. Suggested by 856838032Speter Gerry Magennis of Logica International. 856938032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 857038032Speter when running DNS. For example, if the name FTP.Foo.ORG is 857138032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 857238032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 857338032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 857438032Speter This is technically illegal under RFC 822 and 1123, but the 857538032Speter IETF is moving toward legalizing it. Note that turning on 857638032Speter this option is not sufficient to guarantee that a downstream 857738032Speter neighbor won't rewrite the address for you. 857838032Speter Add "-m" flag to makesendmail script -- this tells you what object 857938032Speter directory and Makefile it will use, but doesn't actually do 858038032Speter the make. 858138032Speter Do some additional checking on the contents of the qf file to try 858238032Speter to detect attacks against the qf file. In particular, 858338032Speter abort on any line beginning "From ", and add an "end of 858438032Speter file" line -- any data after that line is prohibited. 858538032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 858638032Speter choices. This can be overridden in the Makefile by using 858738032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 858838032Speter (to the extent that we know it) or by defining 858938032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 859038032Speter sendmail 8 to have more consistent installation instructions. 859138032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 859238032Speter of Sun Microsystems. 859338032Speter Improved symbol table hash function from Eric Wassenaar. This one 859438032Speter is at least 50% faster. 859538032Speter Fix problem that didn't notice that timeout on file open was a 859638032Speter transient error. Fix from Larry Parmelee of Cornell 859738032Speter University. 859838032Speter Allow comments (lines beginning with a `#') in files read for 859938032Speter classes. Suggested by Motonori Nakamura. 860038032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 860138032Speter of dropping out entirely. This makes testing some of the 860238032Speter name server lookups easier to deal with when there are 860338032Speter hung servers. From Motonori Nakamura. 860438032Speter Add new ${opMode} macro that is set to the current operation mode 860538032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 860638032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 860738032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 860838032Speter Kind of like queue-only mode (Odq) except it tries to avoid 860938032Speter any external service requests; for dial-on-demand hosts that 861038032Speter want to minimize DNS lookups when mail is being queued. For 861138032Speter this to work you will also have to make sure that gethostbyname 861238032Speter of your local host name does not do a DNS lookup. 861338032Speter Improved handling of "out of space" conditions from John Myers of 861438032Speter Carnegie Mellon. 861538032Speter Improved security for mailing to files on systems that have fchmod(2) 861638032Speter support. 861738032Speter Improve "cannot send message for N days" message -- now says "could 861838032Speter not send for past N days". Suggested by Tom Moore of AT&T 861938032Speter Global Information Solutions. 862038032Speter Less misleading Subject: line on messages sent to postmaster only. 862138032Speter From Motonori Nakamura. 862238032Speter Avoid duplicate error messages on bad command line flags.

Problem reported by David 863038032Speter James of British Telecom. 863138032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 863238032Speter from Alexander Dupuy of System Management ARTS. 863338032Speter Delete duplicates in MX lists -- believe it or not, there are sites 863438032Speter that list the same host twice in an MX list. This deletion 863538032Speter only works on adjacent preferences, so an MX list that 863638032Speter had A=5, B=10, A=15 would leave both As, but one that had 863738032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 863838032Speter just in case there is something weird I haven't thought of. 863938032Speter Suggested by Barry Shein of Software Tool & Die. 864038032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 873538032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 873638032Speter University of Brno (Czech Republic). 873738032Speter KSR OS 1.2.2 support from Todd Miller of the University 873838032Speter of Colorado. 873938032Speter UX4800 support from Kazuhisa Shimizu of NEC. 874038032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 874138032Speter in type ``btree'' maps. The semantics of this are undefined 874238032Speter for regular maps, but it can be useful for the user database. 874338032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 874438032Speter lookups while the rebuild is going on. There is a race 874538032Speter condition between the open(... O_TRUNC ...) and the lock 874638032Speter on the file, but it should be quite small. 874738032Speter SMRSH: sendmail restricted shell added to the release. This can 874838032Speter be used as an alternative to /bin/sh for the "prog" mailer, 874938032Speter giving the local administrator more control over what 875038032Speter programs can be run from sendmail. 875138032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 875238032Speter part of the release proper, and isn't fully supported; in 875338032Speter particular, it does not run on System V based systems and 875438032Speter never will. 875538032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 875638032Speter to allow rmail to compile on systems that don't have 875738032Speter function prototypes and systems that don't have snprintf. 875838032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 875938032Speter lists by transaction delay times so that addresses that 876038032Speter respond quickly get sent first. This is to prevent very 876138032Speter sluggish servers from delaying other peoples' mail. 876238032Speter Contributed by Tony Sanders of BSDI. 876338032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 876438032Speter of BSDI. This has a lot of comments to help people out. 876538032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 876638032Speter put this on the m4 command line. On GNU m4 (which 876738032Speter supports the __file__ primitive) you can run m4 in an 876838032Speter arbitrary directory -- use either: 876938032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 877038032Speter or 877138032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 877238032Speter On other versions of m4 that don't support __file__, you 877338032Speter can use: 877438032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 877538032Speter (Note the trailing slash on the _CF_DIR_ definition.) 877638032Speter Old versions of m4 will default to _CF_DIR_=.. for back 877738032Speter compatibility. 877838032Speter CONFIG: fix mail from <> so it will properly convert to 877938032Speter MAILER-DAEMON on local addresses. 878038032Speter CONFIG: fix code that was supposed to catch colons in host 878138032Speter names. Problem noted by John Gardiner Myers of CMU. 878238032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 878338032Speter From Paul Riddle of the University of Maryland, Baltimore 878438032Speter County. 878538032Speter CONFIG: Catch and reject "." as a host address. 878638032Speter CONFIG: Generalize domaintable to look up all domains, not 878738032Speter just unqualified ones. 878838032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 878938032Speter was never used and didn't work anyway. 879038032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 879138032Speter and d on all mailers in the UUCP class. 879238032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 879338032Speter look for an alias for "user+detail", then for "user+*", and 879438032Speter finally for "user". This is intended for forwarding mail 879538032Speter for system aliases such as root and postmaster to a 879638032Speter centralized hub. 879738032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 879838032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 879938032Speter The F=8 flag is also set on the "relay" mailer, since 880038032Speter this is expected to be another sendmail. 880138032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 880238032Speter the name of the UUCP_RELAY -- in some cases, this is the 880338032Speter wrong value (e.g., when we have local UUCP connections), 880438032Speter and this can create unreplyable addresses. From Chip 880538032Speter Rosenthal of Unicom. 880638032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 880764562Sgshapiro Received: header inserted into all messages. Suggested by 880838032Speter Gary Mills of the University of Manitoba. 880938032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 881043730Speter to get the old behavior. I did this upon observing 881138032Speter that almost everyone needed this feature, and that the 881238032Speter concept I was trying to make happen didn't work with 881338032Speter some user agents anyway. FEATURE(notsticky) still works, 881438032Speter but it is a no-op. 881538032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 881638032Speter names are sent, rather than immediately diagnosing them 881738032Speter as User Unknown. 881838032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 881938032Speter and RELAY_MAILER_ARGS to set the arguments for the 882038032Speter indicated mailers. All default to "IPC $h". Patch from 882138032Speter Larry Parmelee of Cornell University. 882238032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 882338032Speter on the client side" and F=P to get an appropriate 882438032Speter return-path. From Kimmo Suominen. 882538032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 882638032Speter as the local mailer. For addresses of the form "user+detail" 882738032Speter the "detail" part is passed to procmail via the -a flag. 882838032Speter Contributed by Kimmo Suominen. 882938032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 883038032Speter use from mailertables. This lets you execute arbitrary 883138032Speter procmail scripts. Contributed by Kimmo Suominen. 883238032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 883338032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 883438032Speter Paul Southworth of CICNet Systems Support. 883538032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 883638032Speter This causes the null return path to be rewritten as 883738032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 883838032Speter From Michael Hohmuth of Technische Universitat Dresden. 883938032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 884038032Speter list us as the best possible MX record to be treated as 884138032Speter though they were local (essentially, assume that they 884238032Speter are included in $=w). This can cause additional DNS 884338032Speter traffic, but is easier to administer if this fits your 884438032Speter local model. It does not work reliably if there are 884538032Speter multiple hosts that share the best MX preference. 884638032Speter Code contributed by John Oleynick of Rutgers. 884738032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 884838032Speter SHell) instead of /bin/sh as the program used for delivery 884938032Speter to programs. If an argument is included, it is used as 885038032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 885138032Speter assumed. 885238032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 885338032Speter size of messages to the local and procmail mailers 885438032Speter respectively. Contributed by Brad Knowles of the Defense 885538032Speter Information Systems Agency. 885638032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 885738032Speter (just like text outside of angle brackets) in order to 885838032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 885938032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 886038032Speter any real systems any more) and tweak the DOMAIN macro 886138032Speter so that it is less likely that users will accidentally use 886238032Speter the Berkeley defaults. Also, create some generic files 886338032Speter that really can be used in the real world. 886438032Speter CONFIG: Add new configuration macros to set character sets for 886538032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 886638032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 886738032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 886838032Speter The old name will still be accepted for a while at least. 886938032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 887038032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 887138032Speter As with all relays, it can be ``mailer:hostname''. Suggested 887238032Speter by Scott Hutton. 887338032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 887438032Speter by Barb Dijker of Labyrinth Computer Services. 887538032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 887638032Speter performance for large alias files, and this confused many 887738032Speter people. 887838032Speter CONFIG: Add confCF_VERSION to append local information to the 887938032Speter configuration version number displayed during SMTP startup. 888038032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 888138032Speter would only work when locally addressed. Fix from 888238032Speter Edvard Tuinder of Cistron Internet Services. 888338032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 888443730Speter "n" (CheckAliases) is set when rebuilding alias database. 888538032Speter Based on code contributed by Claude Marinier. 888638032Speter CONFIG: Allow mailertable to have values of the form 888738032Speter ``error:code message''. The ``code'' is a status code 888838032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 888938032Speter Contributed by David James <dwj@agw.bt.co.uk>. 889038032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 889138032Speter sender domains that will be replaced with the masquerade name. 889238032Speter These domains will not be treated as local, but if mail passes 889338032Speter through with sender addresses in those domains they will be 889438032Speter replaced by the masquerade name. These can also be specified 889538032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 889638032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 889738032Speter as well as the header. Substantial improvements to this 889838032Speter code were contributed by Per Hedeland. 889938032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 890038032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 890138032Speter by Kimmo Suominen. 890238032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 890338032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 890438032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 890538032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 890638032Speter UUCP addressing.

This caused UnixWare 904938032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 905038032Speter Novell Labs Europe. 905138032Speter Fix problem with static linking of local getopt routine when 905238032Speter using GNU's ld command. Fix from John Kennedy of 905338032Speter Cal State Chico. 905438032Speter It was possible to turn off privacy flags. Problem noted by 905538032Speter *Hobbit*. 905638032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 905738032Speter and Liudvikas Bukys. 905838032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 905938032Speter from Spider Boardman. 906038032Speter CONFIG: No changes (version number only, to keep it in sync 906138032Speter with the binaries). 906238032Speter 906364562Sgshapiro8.6.10/8.6.10 1995/02/10 906438032Speter SECURITY: Diagnose bogus values to some command line flags that 906538032Speter could allow trash to get into headers and qf files. 906638032Speter Validate the name of the user returned by the IDENT protocol. 906738032Speter Some systems that really dislike IDENT send intentionally 906838032Speter bogus information. Problem pointed out by Michael Bushnell 906938032Speter of the Free Software Foundation. Has some security 907038032Speter implications. 907138032Speter Fix a problem causing error messages about DNS problems when 907238032Speter the host name contained a percent sign to act oddly 907338032Speter because it was passed as a printf-style format string. 907438032Speter In some cases this could cause core dumps. 907538032Speter Avoid possible buffer overrun in returntosender() if error 907638032Speter message is quite long. From Fletcher Mattox of the 907738032Speter University of Texas. 907838032Speter Fix a problem that would silently drop "too many hops" error 907938032Speter messages if and only if you were sending to an alias. 908038032Speter From Jon Giltner of the University of Colorado and 908138032Speter Dan Harton of Oak Ridge National Laboratory. 908238032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 908338032Speter set and e->e_message was null. Fix from Bruce Nagel of 908438032Speter Data General. 908538032Speter Fix problem that can still cause df files to be left around 908638032Speter after "hop count exceeded" messages. Fix from Andrew 908738032Speter Chang and Shau-Ping Lo of SunSoft. 908838032Speter Fix a problem that can cause buffer overflows on very long 908938032Speter user names (as might occur if you piped to a program 909038032Speter with a lot of arguments). 909138032Speter Avoid returning an error and re-queueing if the host signature 909238032Speter is null; this can occur on addresses like ``user@.''. 909338032Speter Problem noted by Wesley Craig and the University of 909438032Speter Michigan. 909538032Speter Avoid possible calls to malloc(0) if MCI caching is turned 909638032Speter off. Bug fix from Pierre David of the Laboratoire 909738032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 909838032Speter Universite de Versailles - St Quentin, and Jacky 909938032Speter Thibault. 910038032Speter Make a local copy of the line being sent via senttolist() -- in 910138032Speter some cases, buffers could get trashed by map lookups 910238032Speter causing it to do unexpected things. This also simplifies 910338032Speter some of the map code. 910438032Speter CONFIG: No changes (version number only, to keep it in sync 910538032Speter with the binaries). 910638032Speter 910764562Sgshapiro8.6.9/8.6.9 1994/04/19 910838032Speter Do all mail delivery completely disconnected from any terminal. 910938032Speter This provides consistency with daemon delivery and 911038032Speter may have some security implications. 911138032Speter Make sure that malloc doesn't get called with zero size, 911238032Speter since that fails on some systems. Reported by Ed 911338032Speter Hill of the University of Iowa. 911438032Speter Fix multi-line values for $e (SMTP greeting message). Reported 911538032Speter by Mike O'Connor of Ford Motor Company. 911638032Speter Avoid syserr if no NIS domain name is defined, but the map it 911738032Speter is trying to open is optional. From Win Bent of USC. 911838032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 911938032Speter Hesiod support for UDB from Todd Miller of the University of 912038032Speter Colorado. Use "hesiod" as the service name in the U 912138032Speter option. 912238032Speter Fix a problem that failed to set the "authentic" host name (that 912338032Speter is, the one derived from the socket info) if you called 912438032Speter sendmail -bs from inetd. Based on code contributed by 912538032Speter Todd Miller (this problem was also reported by Guy Helmer 912638032Speter of Dakota State University). This also fixes a related 912738032Speter problem reported by Liudvikas Bukys of the University of 912838032Speter Rochester. 912938032Speter Parameterize "nroff -h" in all the Makefiles so people with 913038032Speter variant versions can use them easily. Suggested by 913138032Speter Peter Collinson of Hillside Systems. 913238032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 913338032Speter spaces between parameters instead of one. Reported by 913438032Speter Valdis Kletnieks of Virginia Tech. 913538032Speter Reduce the number of system calls during message collection by 913638032Speter using global timeouts around the collect() loop. This 913738032Speter code was contributed by Eric Wassenaar. 913838032Speter If the initial hostname name gathering results in a name 913938032Speter without a dot (usually caused by NIS misconfiguration) 914038032Speter and BIND is compiled in, directly access DNS to get 914138032Speter the canonical name. This should make life easier for 914238032Speter Solaris systems. If it still can't be resolved, and 914338032Speter if the name server is listed as "required", try again 914438032Speter in 30 seconds. If that also fails, exit immediately to 914538032Speter avoid bogus "config error: mail loops back to myself" 914638032Speter messages. 914738032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 914838032Speter message to explain how much space was available and 914938032Speter sound a bit less threatening. Suggested by Stan Janet 915038032Speter of the National Institute of Standards and Technology. 915138032Speter If mail is delivered to an alias that has an owner, deliver any 915238032Speter requested return-receipt immediately, and strip the 915338032Speter Return-Receipt-To: header from the subsequent message. 915438032Speter This prevents a certain class of denial of service 915538032Speter attack, arguably gives more reasonable semantics, and 915638032Speter moves things more towards what will probably become a 915738032Speter network standard. Suggested by Christopher Davis of 915838032Speter Kapor Enterprises. 915938032Speter Add a "noreceipts" privacy flag to turn off all return receipts 916038032Speter without recompiling. 916138032Speter Avoid printing ESMTP parameters as part of the error message 916238032Speter if there are errors during parsing. This change is 916338032Speter purely cosmetic. 916438032Speter Avoid sending out error messages during the collect phase of 916538032Speter SMTP; there is an MVS mailer from UCLA that gets 916638032Speter confused by this. Of course, I think it's their bug.... 916738032Speter Check for the $j macro getting undefined, losing a dot, or getting 916838032Speter lost from $=w in the daemon before accepting a connection; 916938032Speter if it is, it dumps state, prints a LOG_ALERT message, 917038032Speter and drops core for debugging. This is an attempt to 917138032Speter track down a bug that I thought was long since gone. 917238032Speter If you see this, please forward the log fragment to 917338032Speter sendmail@sendmail.ORG. 917438032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 917538032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 917638032Speter Wolfhugel. 917738032Speter Instead of trying to truncate the listen queue for the server 917838032Speter SMTP port when the load average is too high, just close 917938032Speter the port completely and reopen it later as needed. 918038032Speter This ensures that the other end gets a quick "connection 918138032Speter refused" response, and that the connection can be 918238032Speter recovered later. In particular, some socket emulations 918338032Speter seem to get confused if you tweak the listen queue 918438032Speter size around and can never start listening to connections 918538032Speter again. The down side is that someone could start up 918638032Speter another daemon process in the interim, so you could 918738032Speter have multiple daemons all not listening to connections; 918838032Speter this could in turn cause the sendmail.pid file to be 918938032Speter incorrect. A better approach might be to accept the 919038032Speter connection and give a 421 code, but that could break 919143730Speter other mailers in mysterious ways and have paging behavior 919238032Speter implications. 919338032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 919438032Speter set debugging on the wrong socket. From Eric Wassenaar. 919538032Speter When creating a df* temporary file, be sure you truncate any 919638032Speter existing data in the file -- otherwise system crashes 919738032Speter and the like could result in extra data being sent. 919838032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 919938032Speter doc directory. This includes some additional 920038032Speter information. 920138032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 920238032Speter of recipient envelope addresses. This should have been 920338032Speter handled by the $&h trick, but broke if people were 920438032Speter mixing domainized and UUCP addresses. They should 920538032Speter probably have converted all the way over to uucp-uudom 920638032Speter instead of uucp-{new,old}, but the failure mode was to 920738032Speter loop the mail, which was bad news. 920838032Speter Portability fixes: 920938032Speter Newer BSDI systems (several people). 921038032Speter Older BSDI systems from Christophe Wolfhugel. 921138032Speter Intergraph CLIX, from Paul Southworth of CICNet. 921238032Speter UnixWare, from Evan Champion. 921338032Speter NetBSD from Adam Glass. 921438032Speter Solaris from Quentin Campbell of the University of 921538032Speter Newcastle upon Tyne. 921638032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 921738032Speter Corporation. 921838032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 921938032Speter SunOS (it has setsid() and setvbuf() calls) from 922038032Speter Jonathan Kamens of OpenVision Technologies. 922138032Speter HP-UX from Tor Lillqvist. 922238032Speter New Files: 922338032Speter src/Makefile.CLIX 922438032Speter src/Makefile.NCR3000 922538032Speter doc/changes/Makefile 922638032Speter doc/changes/changes.me 922738032Speter doc/changes/changes.ps 922838032Speter 922964562Sgshapiro8.6.8/8.6.6 1994/03/21 923038032Speter SECURITY: it was possible to read any file as root using the 923138032Speter E (error message) option. Reported by Richard Jones; 923238032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 923338032Speter 923464562Sgshapiro8.6.7/8.6.6 1994/03/14 923538032Speter SECURITY: it was possible to get root access by using weird 923638032Speter values to the -d flag. Thanks to Alain Durand of 923738032Speter INRIA for forwarding me the notice from the bugtraq 923838032Speter list. 923938032Speter 924064562Sgshapiro8.6.6/8.6.6 1994/03/13 924138032Speter SECURITY: the ability to give files away on System V-based 924238032Speter systems proved dangerous -- don't run as the owner 924338032Speter of a :include: file on a system that allows giveaways. 924438032Speter Unfortunately, this also applies to determining a 924538032Speter valid shell. 924638032Speter IMPORTANT: Previous versions weren't expiring old connections 924738032Speter in the connection cache for a long time under some 924838032Speter circumstances. This could result in resource exhaustion, 924938032Speter both at your end and at the other end. This checks the 925038032Speter connections for timeouts much more frequently. From 925138032Speter Doug Anderson of NCSC. 925238032Speter Fix a glitch that snuck in that caused programs to be run as 925338032Speter the sender instead of the recipient if the mail was 925438032Speter from a local user to another local user. From 925538032Speter Motonori Nakamura of Kyoto University. 925638032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 925738032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 925838032Speter Bryan Costales of ICSI. 925938032Speter Change the method used to declare the "statfs" availability; 926038032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 926138032Speter tweaking in conf.c, there is a single #define called 926238032Speter SFS_TYPE which takes on one of six values (SFS_NONE 926338032Speter for no statfs availability, SFS_USTAT for the ustat(2) 926438032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 926538032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 926638032Speter statfs(2) call with the declarations in <sys/vfs.h>, 926738032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 926838032Speter Fix glitch in NetInfo support that could return garbage if 926938032Speter there was no "/locations/sendmail" property. From 927038032Speter David Meyer of the University of Virginia. 927138032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 927238032Speter to allow Linux to turn it off even though it is a 927338032Speter BSD-like system. 927438032Speter Allow setting of "ident" timeout to zero to turn off the ident 927538032Speter protocol entirely. 927638032Speter Make 7-bit stripping local to a connection (instead of to a 927738032Speter mailer); this allows you to specify that SMTP is a 927838032Speter 7-bit channel, but revert to 8-bit should it advertise 927938032Speter that it supports 8BITMIME. You still have to specify 928038032Speter mailer flag 7 to get this stripping at all. 928138032Speter Improve makesendmail script so it handles more cases automatically. 928238032Speter Tighten up restrictions on taking ownership of :include: files 928338032Speter to avoid problems on systems that allow you to give away 928438032Speter files. 928538032Speter Fix a problem that made it impossible to rebuild the alias 928638032Speter file if it was on a read-only file system. From 928738032Speter Harry Edmon of the University of Washington. 928838032Speter Improve MX randomization function. From John Gardiner Myers 928938032Speter of CMU. 929038032Speter Fix a minor glitch causing a bogus message to be printed (used 929138032Speter %s instead of %d in a printf string for the line number) 929238032Speter when a bad queue file was read. From Harry Edmon. 929338032Speter Allow $s to remain NULL on locally generated mail. I'm not 929438032Speter sure this is necessary, but a lot of people have complained 929538032Speter about it, and there is a legitimate question as to whether 929638032Speter "localhost" is legal as an 822-style domain. 929738032Speter Fix a problem with very short line lengths (mailer L= flag) in 929838032Speter headers. This causes a leading space to be added onto 929938032Speter continuation lines (including in the body!), and also 930038032Speter tries to wrap headers containing addresses (From:, To:, 930138032Speter etc) intelligently at the shorter line lengths. Problem 930238032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 930338032Speter Log the real user name when logging syserrs, since these can have 930438032Speter security implications. Suggested by several people. 930538032Speter Fix address logging of cached connections -- it used to always 930638032Speter log the numeric address as zero. This is a somewhat 930738032Speter bogus implementation in that it does an extra system 930838032Speter call, but it should be an inexpensive one. Fix from 930938032Speter Motonori Nakamura. 931038032Speter Tighten up handling of short syslog buffers even more -- there 931138032Speter were cases where the outgoing relay= name was too long 931238032Speter to share a line with delay= and mailer= logging. 931338032Speter Limit the overhead on split envelopes to one open file descriptor 931438032Speter per envelope -- previously the overhead was three 931538032Speter descriptors. This was in response to a problem reported 931638032Speter by P{r (Pell) Emanuelsson. 931738032Speter Fixes to better handle the case of unexpected connection closes; 931838032Speter this redirects the output to the transcript so the info 931938032Speter is not lost. From Eric Wassenaar. 932038032Speter Fix potential string overrun if you macro evaluate a string that 932138032Speter has a naked $ at the end. Problem noted by James Matheson 932238032Speter <jmrm@eng.cam.ac.uk>. 932338032Speter Make default error number on $#error messages 553 (``Requested 932438032Speter action not taken: mailbox name not allowed'') instead of 932538032Speter 501 (``Syntax error in parameters or arguments'') to 932638032Speter avoid bogus "protocol error" messages. 932738032Speter Strip off any existing trailing dot on names during $[ ... $] 932838032Speter lookup. This prevents it from ending up with two dots 932938032Speter on the end of dot terminated names. From Wesley Craig 933038032Speter of the University of Michigan and Bryan Costales of ICSI. 933138032Speter Clean up file class reading so that the debugging information is 933238032Speter more informative. It hadn't been using setclass, so you 933338032Speter didn't see the class items being added. 933438032Speter Avoid core dump if you are running a version of sendmail where 933538032Speter NIS is compiled in, and you specify an NIS map, but 933638032Speter NIS is not running. Fix from John Oleynick of 933738032Speter Rutgers. 933838032Speter Diagnose bizarre case where res_search returns a failure value, 933938032Speter but sets h_errno to a success value. 934038032Speter Make sure that "too many hops" messages are considered important 934138032Speter enough to send an error to the Postmaster (that is, the 934238032Speter address specified in the P option). This fix should 934338032Speter help problems that cause the df file to be left around 934438032Speter sometimes -- unfortunately, I can't seem to reproduce 934538032Speter the problem myself. 934638032Speter Avoid core dump (null pointer reference) on EXPN command; this 934738032Speter only occurred if your log level was set to 10 or higher 934838032Speter and the target account was an alias or had a .forward file. 934938032Speter Problem noted by Janne Himanka. 935038032Speter Avoid "denial of service" attacks by someone who is flooding your 935138032Speter SMTP port with bad commands by shutting the connection 935238032Speter after 25 bad commands are issued. From Kyle Jones of 935338032Speter UUNET. 935438032Speter Fix core dump on error messages with very long "to" buffers; 935538032Speter fmtmsg overflows the message buffer. Fixed by trimming 935638032Speter the to address to 203 characters. Problem reported by 935738032Speter John Oleynick. 935838032Speter Fix configuration for HASFLOCK -- there were some spots where 935938032Speter a #ifndef was incorrectly #ifdef. Pointed out by 936038032Speter George Baltz of the University of Maryland. 936138032Speter Fix a typo in savemail() that could cause the error message To: 936238032Speter lists to be incorrect in some places. From Motonori 936338032Speter Nakamura. 936438032Speter Fix a glitch that can cause duplicate error messages on split 936538032Speter envelopes where an address on one of the lists has a 936638032Speter name server failure. Fix from Voradesh Yenbut of the 936738032Speter University of Washington. 936838032Speter Fix possible bogus pointer reference on ESMTP parameters that 936938032Speter don't have an ``=value'' part. 937038032Speter CNAME loops caused an error message to be generated, but also 937138032Speter re-queued the message. Changed to just re-queue the 937238032Speter message (it's really hard to just bounce it because 937338032Speter of the weird way the name server works in the presence 937438032Speter of CNAME loops). Problem noted by James M.R.Matheson 937538032Speter of Cambridge University. 937638032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 937738032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 937838032Speter user name. Suggested by Andreas Stolcke of ICSI. 937938032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 938038032Speter override it easily in the Makefile -- that is, you can 938138032Speter turn it off using -DNAMED_BIND=0. 938238032Speter If a gethostbyname(...) of an address with a trailing dot fails, 938338032Speter try it without the trailing dot. This is because if 938438032Speter you have a version of gethostbyname() that falls back 938538032Speter to NIS or the /etc/hosts file it will fail to find 938638032Speter perfectly reasonable names that just don't happen to 938738032Speter be dot terminated in the hosts file. You don't want to 938838032Speter strip the dot first though because we're trying to ensure 938938032Speter that country names that match one of your subdomains get 939038032Speter a chance. 939138032Speter PRALIASES: fix bogus output on non-null-terminated strings. 939238032Speter From Bill Gianopoulos of Raytheon. 939338032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 939438032Speter This was in code intended to only catch the self-literal 939538032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 939638032Speter IP address), but the code was broken. However, it will 939738032Speter still do this if $M is defined; this is necessary to 939838032Speter get client configurations to work (sigh). Note that this 939938032Speter means that $M overrides :mailname entries in the user 940038032Speter database! Problem noted by Paul Southworth. 940138032Speter CONFIG: Fix definition of Solaris help file location. From 940238032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 940338032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 940438032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 940538032Speter and USENET_MAILER_MAX to tweak the maximum message 940638032Speter size for various mailers. 940738032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 940838032Speter instead of assuming that it is "inews" for consistency 940938032Speter with other mailers. From Michael Corrigan of UC San Diego. 941038032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 941138032Speter qualify the address in the SMTP envelope as user@{relay|hub} 941238032Speter instead of user@$j. From Bill Wisner of The Well. 941338032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 941438032Speter CONFIG: Don't turn off case mapping of user names in the local 941538032Speter mailer for IRIX. This was different than most every other 941638032Speter system. 941738032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 941838032Speter envelope. Noted by Thierry Besancon 941938032Speter <besancon@excalibur.ens.fr>. 942038032Speter CONFIG: Don't include -z by default on uux line -- most systems 942138032Speter don't want it set by default. Pointed out by Philippe 942238032Speter Michel of Thomson CSF. 942338032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 942438032Speter host name was foo.bar.ray.com and you matched against 942538032Speter ".ray.com", the old implementation bound %1 to "bar" 942638032Speter instead of "foo.bar". Also, allow "." in the mailertable 942738032Speter to match anything -- essentially, take over SMART_HOST. 942838032Speter This also moves matching of explicit local host names 942938032Speter before the mailertable so they don't have to be special 943038032Speter cased in the mailertable data. Reported by Bill 943138032Speter Gianopoulos of Raytheon; the fix for the %1 binding 943238032Speter problem was contributed by Nicholas Comanos of the 943338032Speter University of Sydney. 943438032Speter CONFIG: Don't include "root" in class $=L (users to deliver 943538032Speter locally, even if a hub or relay exists) by default. 943638032Speter This is because of the known bug where definition of 943738032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 943838032Speter both and deliver into the local mailbox. 943938032Speter CONFIG: Move up bitdomain and uudomain handling so that they 944038032Speter are done before .UUCP class matching; uudomain was 944138032Speter reported as ineffective before. This also frees up 944238032Speter diversion 8 for future use. Problem reported by Kimmo 944338032Speter Suominen. 944438032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 944538032Speter into host names. As pointed out by Jonathan Kamens, 944638032Speter these are often used because either the forward or reverse 944738032Speter mapping is broken; this translation makes it broken again. 944838032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 944938032Speter Suominen. 945038032Speter Portability fixes: 945138032Speter Unicos from David L.

From 947538032Speter Bob Campbell at U.C. Berkeley. 947638032Speter Security fix: group ids were not completely set when programs 947738032Speter were invoked. This caused programs to have group 947838032Speter permissions they should not have had (usually group 947938032Speter daemon instead of their own group). In particular, 948038032Speter Perl scripts would refuse to run. 948138032Speter Security: check to make sure files that are written are not 948238032Speter symbolic links (at least under some circumstances). 948338032Speter Although this does not respond to a specific known 948438032Speter attack, it's just a good idea. Suggested by 948538032Speter Christian Wettergren. 948638032Speter Security fix: if a user had an NFS mounted home directory on 948738032Speter a system with a restricted shell listed in their 948838032Speter /etc/passwd entry, they could still execute any 948938032Speter program by putting that in their .forward file. 949038032Speter This fix prevents that by insisting that their shell 949138032Speter appear in /etc/shells before allowing a .forward to 949238032Speter execute a program or write a file. You can disable 949338032Speter this by putting "*" in /etc/shells. It also won't 949438032Speter permit world-writable :include: files to reference 949538032Speter programs or files (there's no way to disable this). 949643730Speter These behaviors are only one level deep -- for 949738032Speter example, it is legal for a world-writable :include: 949838032Speter file to reference an alias that writes a file, on 949938032Speter the assumption that the alias file is well controlled. 950038032Speter Security fix: root was not treated suspiciously enough when 950138032Speter looking into subdirectories. This would potentially 950238032Speter allow a cracker to examine files that were publicly 950338032Speter readable but in a non-publicly searchable directory. 950438032Speter Fix a problem that causes an error on QUIT on a cached 950538032Speter connection to create problems on the current job. 950638032Speter These are typically unrelated, so errors occur in 950738032Speter the wrong place. 950838032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 950938032Speter runs more responsive to load average, and fixes a 951038032Speter problem that ignored the load average in locally 951138032Speter generated mail. From Eric Wassenaar. 951238032Speter Fix possible core dump on aliases with null LHS. From 951338032Speter John Orthoefer of BB&N. 951438032Speter Revert to using flock() whenever possible -- there are just 951538032Speter too many bugs in fcntl() locking, particularly over 951638032Speter NFS, that cause sendmail to fail in perverse ways. 951738032Speter Fix a bug that causes the connection cache to get confused 951838032Speter when sending error messages. This resulted in 951938032Speter "unexpected close" messages. It should fix itself 952038032Speter on the following queue run. Problem noted by 952138032Speter Liudvikas Bukys of the University of Rochester. 952238032Speter Include $k in $=k as documented in the Install & Op Guide. 952338032Speter This seems odd, but it was documented.... From 952438032Speter Michael Corrigan of UCSD. 952538032Speter Fix problem that caused :include:s from alias files to be 952638032Speter forced to be owned by root instead of daemon 952738032Speter (actually DefUid). From Tim Irvin. 952838032Speter Diagnose unrecognized I option values -- from Mortin Forssen 952938032Speter of the Chalmers University of Technology. 953038032Speter Make "error" mailer work consistently when there is no error 953138032Speter code associated with it -- previously it returned OK 953238032Speter even though there was a real problem. Now it assumes 953338032Speter EX_UNAVAILABLE. 953438032Speter Fix bug that caused the last header line of messages that had 953538032Speter no body and which were terminated with EOF instead of 953638032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 953738032Speter Fix core dump on SMTP mail to programs that failed -- it tried 953838032Speter to go to a "next MX host" when none existed, causing 953938032Speter a core dump. From der Mouse at McGill University. 954038032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 954138032Speter this makes it easier to turn it off (using 954238032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 954338032Speter Fix YP_MASTER_NAME store to use the unupdated result of 954438032Speter gethostname() (instead of myhostname(), which tries 954538032Speter to fully qualify the name) to be consistent with 954638032Speter SunOS. If your hostname is unqualified, this fixes 954738032Speter transfers to slave servers. Bug noted by Keith 954838032Speter McMillan of Ameritech Services, Inc. 954938032Speter Fix Ultrix problem: gethostbyname() can return a very large 955038032Speter (> 500) h_length field, which causes the sockaddr 955138032Speter to be trashed. Use the size of the sockaddr instead. 955238032Speter Fix from Bob Manson of Ohio State. 955338032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 955438032Speter defined -- this confuses gethostbyname on hosts 955538032Speter file lookups, which doesn't understand the trailing 955638032Speter dot convention. 955738032Speter Log SMTP server subprocesses that die with a signal instead 955838032Speter of from a clean exit. 955938032Speter If you don't have option "I" set, don't assume that a DNS 956038032Speter "host unknown" message is authoritative -- it 956138032Speter might still be found in /etc/hosts. 956238032Speter Fix a problem that would cause Deferred: messages to be sent 956338032Speter as the subject of an error message, even though the 956438032Speter actual cause of a message was more severe than that. 956538032Speter Problem noted by Chris Seabrook of OSSI. 956638032Speter Fix race condition in DBM alias file locking. From Kyle 956738032Speter Jones of UUNET. 956838032Speter Limit delivery syslog line length to avoid bugs in some 956938032Speter versions of syslog(3). This adds a new compile time 957038032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 957138032Speter University, which is in turn derived from IDA. 957238032Speter Fix quotes inside of comments in addresses -- previously 957338032Speter it insisted that they be balanced, but the 822 spec 957438032Speter says that they should be ignored. 957538032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 957638032Speter debugging). This also evaluates ruleset 89, if set 957738032Speter (with the null input), and logs the result. This 957838032Speter should be used sparingly, since the rewrite process 957938032Speter is not reentrant. 958038032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 958138032Speter documented in the Bat Book. 958238032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 958338032Speter return an error message and did not requeue the message. 958438032Speter Fix based on code from Roland Dirlewanger of 958538032Speter Reseau Regional Aquarel, Bordeaux, France. 958638032Speter Fix a problem that caused a seg fault if you got a 421 error 958738032Speter code during some parts of connection initialization. 958838032Speter I've only seen this when talking to buggy mailers on 958938032Speter the other end, but it shouldn't give a seg fault in 959038032Speter any case.

Noted by William C Fenner of 963238032Speter the NRL Connection Machine Facility. 963338032Speter Fix a problem that could cause a core dump if the input sequence 963438032Speter had (or somehow acquired) a \231 character. 963538032Speter Make sure that route-addrs always have <angle brackets> around 963638032Speter them in non-SMTP envelopes (SMTP envelopes already do 963738032Speter this properly). 963838032Speter Avoid weird headers on unbalanced punctuation of the form: 963938032Speter ``Joe User <user)'' -- this caused reference to the 964038032Speter null macro. Fix from Rick McCarty of IO.COM. 964138032Speter Fix a problem that caused an alias "user: user@local.host" to 964238032Speter not have the QNOTREMOTE bit set; this caused configs 964338032Speter to act as if FEATURE(notsticky) was defined even when 964438032Speter it was not. The effect of the problem was to make it 964538032Speter very hard to to set up satellite sites that had a few 964638032Speter local accounts, with everything else forwarded to a 964738032Speter corporate hub. Reported by Detlef Drewanz of the 964838032Speter University of Rostock and Mark Frost of NCD. 964938032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 965038032Speter addresses. This is more efficient (fewer name server 965138032Speter calls) and fixes certain unusual configurations, such 965238032Speter as those that have ruleset 4 do something that is 965338032Speter non-idempotent unless a mailer-specific ruleset did 965438032Speter something else.

Briefly, if you are sending to host 972338032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 972438032Speter "foo!baz" remains "foo!baz", and anything else has 972538032Speter the local name prepended. 972638032Speter CONFIG: portability fixes for HP-UX. 972738032Speter DOC: several minor problems fixed in the Install & Op Guide. 972838032Speter MAKEMAP: fix core dump problem on lines that are too long or 972938032Speter which lack newline. From Mark Delany. 973038032Speter MAILSTATS: print sums of columns (total messages & kbytes 973138032Speter in and out of the system). From Tom Ferrin of UC 973238032Speter San Francisco Computer Graphics Lab. 973338032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 973438032Speter On HP-UX, /etc/sendmail.cf has been moved to 973538032Speter /usr/lib/sendmail.cf to match HP sendmail. 973638032Speter Permissions have been tightened up on world-writable 973738032Speter :include: files and accounts that have shells 973838032Speter that are not listed in /etc/shells. This may 973938032Speter cause some .forward files that have worked 974038032Speter before to start failing. 974138032Speter SIGUSR1 dumps some state to the log. 974238032Speter NEW FILES: 974338032Speter src/Makefile.DGUX 974438032Speter src/Makefile.Dynix 974538032Speter src/Makefile.FreeBSD 974638032Speter src/Makefile.Mach386 974738032Speter src/Makefile.NetBSD 974838032Speter src/Makefile.RISCos 974938032Speter src/Makefile.SCO 975038032Speter src/Makefile.SVR4 975138032Speter src/Makefile.Titan 975238032Speter cf/mailer/pop.m4 975338032Speter cf/ostype/bsdi1.0.m4 975438032Speter cf/ostype/dgux.m4 975538032Speter cf/ostype/dynix3.2.m4 975638032Speter cf/ostype/sco3.2.m4 975738032Speter makemap/Makefile.dist 975838032Speter praliases/Makefile.dist 975938032Speter 976064562Sgshapiro8.6.4/8.6.4 1993/10/31 976138032Speter Repair core-dump problem (write to read-only memory segment) 976238032Speter if you fall back to the return-to-Postmaster case in 976338032Speter savemail. Problem reported by Richard Liu. 976438032Speter Immediately diagnose bogus sender addresses in SMTP. This 976538032Speter makes quite certain that crackers can't use this 976638032Speter class of attack. 976738032Speter Reliability Fix: check return value from fclose() and fsync() 976838032Speter in a few critical places. 976938032Speter Minor problem in initsys() that reversed a condition for 977038032Speter redirecting the output channel on queue runs. It's 977138032Speter not clear this code even does anything. From Eric 977238032Speter Wassenaar of the Dutch National Institute for Nuclear 977338032Speter and High-Energy Physics. 977438032Speter Fix some problems that caused queue runs to do "too much work", 977538032Speter such as double-reading the Errors-To: header. From 977638032Speter Eric Wassenaar. 977738032Speter Error messages on writing the temporary file (including the 977838032Speter data file) were getting suppressed in SMTP -- this 977938032Speter fix causes them to be properly reported. From Eric 978038032Speter Wassenaar. 978138032Speter Some changes to support AF_UNIX sockets -- this will only 978238032Speter really become relevant in the next release, but some 978338032Speter people need it for local patches. From Michael 978438032Speter Corrigan of UC San Diego. 978538032Speter Use dynamically allocated memory (instead of static buffers) 978638032Speter for macros defined in initsys() and settime(); since 978738032Speter these can have different values depending on which 978838032Speter envelope they are in. From Eric Wassenaar. 978938032Speter Improve logging to show ctladdr on to= logging; this tells you 979038032Speter what uid/gid processes ran as. 979138032Speter Fix a problem that caused error messages to be discarded if 979238032Speter the sender address was unparseable for some reason; 979338032Speter this was supposed to fall back to the "return to 979438032Speter postmaster" case. 979538032Speter Improve aliaswait backoff algorithm. 979638032Speter Portability patches for Linux (8.6.3 required another header 979738032Speter file) (from Karl London) and SCO UNIX. 979838032Speter CONFIG: patch prog mailer to not strip host name off of envelope 979938032Speter addresses (so that it matches local again). From 980038032Speter Christopher Davis. 980138032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 980238032Speter this prevents uux from seeing lines with null names like 980338032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 980438032Speter Nakamura of Kyoto University. 980538032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 980638032Speter it shouldn't fail miserably. From Motonori Nakamura. 980738032Speter 980864562Sgshapiro8.6.2/8.6.2 1993/10/15 980938032Speter Put a "successful delivery" message in the transcript for 981038032Speter addresses that get return-receipts. 981138032Speter Put a prominent "this is only a warning" message in warning 981238032Speter messages -- some people don't read carefully enough 981338032Speter and end up sending the message several times. 981438032Speter Include reason for temporary failure in the "warning" return 981538032Speter message. Currently, it just says "cannot send for 981638032Speter four hours". 981738032Speter Fix the "Original message received" time generated for 981838032Speter returntosender messages. It was previously listed as 981938032Speter the current time. Bug reported by Eric Hagberg of 982038032Speter Cornell University Medical College. 982138032Speter If there is an error when writing the body of a message, 982238032Speter don't send the trailing dot and wait for a response 982338032Speter in sender SMTP, as this could cause the connection to 982438032Speter hang up under some bizarre circumstances. From Eric 982538032Speter Wassenaar. 982638032Speter Fix some server SMTP synchronization problems caused when 982738032Speter connections fail during message collection. From 982838032Speter Eric Wassenaar. 982938032Speter Fix a problem that can cause srvrsmtp to reject mail if the 983038032Speter name server is down -- it accepts the RCPT but rejects 983138032Speter the DATA command. Problem reported by Jim Murray of 983238032Speter Stratus. 983338032Speter Fix a problem that can cause core dumps if the config file 983438032Speter incorrectly resolves to a null hostname. Reported by 983538032Speter Allan Johannesen of WPI. 983638032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 983738032Speter by non-root users were not put into 983838032Speter X-Authentication-Warning:s as intended because the 983943730Speter config file hadn't set the PrivacyOptions yet. Fix 984038032Speter from Sven-Ove Westberg of the University of Lulea. 984138032Speter Under very odd circumstances, the alias file rebuild code 984238032Speter could get confused as to whether a database was 984338032Speter open or not. 984438032Speter Check "vendor code" on the end of V lines -- this is 984538032Speter intended to provide a hook for vendor-specific 984638032Speter configuration syntax. (This is a "new feature", 984738032Speter but I've made an exception to my rule in a belief 984838032Speter that this is a highly exceptional case.) 984938032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 985038032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 985138032Speter (from Jon Forrest of UC Berkeley) 985238032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 985338032Speter 985464562Sgshapiro8.6.1/8.6 1993/10/08 985538032Speter Portability fixes for A/UX and Encore UMAX V. 985638032Speter Fix error message handling -- if you had a name server down 985738032Speter causing an error during parsing, that message was never 985838032Speter propagated to the queue file. 985938032Speter 986064562Sgshapiro8.6/8.6 1993/10/05 986138032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 986238032Speter conf.h (other systems have the same bug). 986338032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 986438032Speter getdtablesize() instead of sysconf(); a disturbingly 986538032Speter large number of systems defined _SC_OPEN_MAX in the 986638032Speter header files but don't have the syscall. 986738032Speter Another patch to really truly ignore MX records in getcanonname 986838032Speter if trymx == FALSE. 986938032Speter Fix problem that caused the "250 IAA25499 Message accepted for 987038032Speter delivery" message to be omitted if there was an error 987138032Speter in the header of the message (e.g., a bad Errors-To: 987238032Speter line). Pointed out by Michael Corrigan of UCSD. 987338032Speter Announce name of host we are chatting when we get errors; this 987438032Speter is an IDA-ism suggested by Christophe Wolfhugel. 987538032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 987638032Speter Australian Artificial Intelligence Institute), SCO Unix 987738032Speter (from Murray Kucherawy of Hookup Communication Corp.), 987838032Speter NeXT (from Vince DeMarco and myself), Linux (from 987938032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 988038032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 988138032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 988238032Speter Some changes to get around gcc optimizer bugs. From Takahiro 988338032Speter Kanbe. 988438032Speter Fix error recovery in queueup if another tf file of the same 988538032Speter name already exists. Problem stumbled over by Bill 988638032Speter Wisner of The Well. 988738032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 988838032Speter Problem noted by Keith McMillan of Ameritech Services. 988938032Speter Deal with group permissions properly when opening .forward and 989038032Speter :include: files. This relaxes the 8.1C restrictions 989138032Speter slightly more. This includes proper setting of groups 989238032Speter when reading :include: files, allowing you to read some 989338032Speter files that you should be able to read but have previously 989438032Speter been denied unless you owned them or they had "other" 989538032Speter read permission. 989638032Speter Make certain that $j is in $=w (after the .cf is read) so that 989738032Speter if the user is forced to override some silly system, 989838032Speter MX suppression will still work. 989938032Speter Fix a couple of efficiency problems where newstr was double- 990038032Speter calling expensive routines. In at least one case, it 990138032Speter wasn't guaranteed that they would always return the 990238032Speter same result. Problem noted by Christophe Wolfhugel. 990338032Speter Fix null pointer dereference in putoutmsg -- only on an error 990438032Speter condition from a non-SMTP mailer. From Motonori 990538032Speter Nakamura. 990638032Speter Macro expand "C" line class definitions before scanning so that 990738032Speter "CX $Z" works. 990838032Speter Fix problem that caused error message to be sent while still 990938032Speter trying to send the original message if the connection 991038032Speter is closed during a DATA command after getting an error 991138032Speter on an RCPT command (pretty obscure). Problem reported 991238032Speter by John Myers of CMU. 991338032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 991438032Speter term bug. 991538032Speter Fix a nasty bug causing core dumps when returning the "warning: 991638032Speter cannot deliver for N hours -- will keep trying" message; 991743730Speter it only occurred if you had PostmasterCopy set and 991838032Speter only on some architectures. Although sendmail would 991938032Speter keep trying, it would send error messages on each 992038032Speter queue interval. This is an important fix. 992138032Speter Allow u and g options to take user and group names respectively. 992238032Speter Don't do a chdir into the queue directory in -bt mode to make 992338032Speter ruleset testing a bit easier. 992438032Speter Don't allow users to turn off logging (using -oL) on the command 992538032Speter line -- command line can only raise, not lower, logging 992638032Speter level. 992738032Speter Set $u to the original recipient on the SMTP transaction or on 992838032Speter the command line. This is only done if there is exactly 992938032Speter one recipient. Technically, this does not meet the 993038032Speter specs, because it does not guarantee a domain on the 993138032Speter address. 993238032Speter Fix a problem that dumped error messages on bad addresses if 993338032Speter you used the -t flag. Problem noted by Josh Smith of 993438032Speter Harvey Mudd College. 993538032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 993638032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 993738032Speter avoid the problem of people who use angle brackets in 993838032Speter their full name information. 993938032Speter Fix a null pointer dereference if you set option "l", have 994038032Speter an Errors-To: header in the message, and have Errors-To: 994138032Speter defined in the config file H lines. From J.R. Oldroyd. 994238032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 994338032Speter wrong when compiling. Suggested by Rick McCarty of TI. 994438032Speter Fix a problem that could pass negative SIZE parameter if the 994538032Speter df file got lost; this would cause servers to always 994638032Speter give a temporary failure, making the problem even worse. 994738032Speter Problem noted by Allan Johannesen of WPI. 994838032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 994938032Speter protocol timeouts (30s default). Requested by Murray 995038032Speter Kucherawy of HookUp Communication Corp. to handle bogus 995138032Speter PC TCP/IP implementations. 995238032Speter Change $w default definition to be just the first component of 995338032Speter the domain name on config level 5. The $j macro defaults 995438032Speter to the FQDN; $m remains as before. This lets well-behaved 995538032Speter config files use any of the short, long, or subdomain 995638032Speter names. 995738032Speter Add makesendmail script in src to try to automate multi-architecture 995838032Speter builds. I know, this is sub-optimal, but it is still 995938032Speter helpful. 996038032Speter Fix very obscure race condition that can cause a queue run to 996138032Speter get a queue file for an already completed job. This 996238032Speter problem has existed for years. Problem noted by the 996338032Speter long suffering Allan Johannesen of WPI. 996438032Speter Fix a problem that caused the raw sender name to be passed to 996538032Speter udbsender instead of the canonified name -- this caused 996638032Speter it to sometimes miss records that it should have found. 996738032Speter Relax check of name on HELO packet so that a program using -bs 996838032Speter that claims to be itself works properly. 996938032Speter Restore rewriting of $: part of address through 2, R, 4 in 997038032Speter buildaddr -- this requires passing a lot of flags to get 997138032Speter it right. Unlike old versions, this ONLY rewrites 997238032Speter recipient addresses, not sender addresses. 997338032Speter Fix a bug that caused core dumps in config files that cannot 997438032Speter resolve /file/name style addresses. Fix from Jonathan 997538032Speter Kamens of OpenVision Technologies. 997638032Speter Fix problem with fcntl locking that can cause error returns to 997738032Speter be lost if the lock is lost; this required fully 997838032Speter queueing everything, dropping the envelope (so errors 997938032Speter would get returned), and then re-reading the queue from 998038032Speter scratch. 998138032Speter Fix a problem that caused aliases that redefine an otherwise 998238032Speter true address to still send to the original address 998338032Speter if and only if the alias failed in certain bizarre 998438032Speter ways (e.g, if they pointed at a list:; syntax address). 998538032Speter Problem pointed out by Jonathan Kamens. 998638032Speter Remove support for frozen configuration files. They caused 998738032Speter more trouble than it was worth. 998838032Speter Fix problem that can cause error messages to get ignored when 998938032Speter using both -odb and -t flags. Problem noted by Rob 999038032Speter McNicholas at U.C. Berkeley. 999138032Speter Include all "normal" variations on hostname in $=w. For example, 999238032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 999338032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 999438032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 999538032Speter the queue. 999638032Speter Reset SmtpPhase global on initial connection creation so that 999738032Speter messages don't come out with stale information. 999838032Speter Pass an "ext" argument to lockfile so that error/log messages 999938032Speter will properly reflect the true filename being locked. 1000038032Speter Put all [...] address forms into $=w -- this eliminates the need 1000138032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 1000238032Speter Myers of CMU. 1000338032Speter Fix a bug that can cause qf files to be left around even after 1000438032Speter an SMTP RSET command. Problem and fix from Michael 1000538032Speter Corrigan. 1000643730Speter Don't send a PostmasterCopy to errors when the Precedence: is 1000738032Speter negative. Error reports still go to the envelope 1000838032Speter sender address. 1000938032Speter Add LA_SHORT for load averages. 1001038032Speter Lock sendmail.st file when posting statistics. 1001138032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 1001238032Speter set the size of the TCP send and receive buffers; if you 1001338032Speter run over a slow slip line you may need to set these down 1001438032Speter (although it would be better to fix the SLIP implementation 1001538032Speter so that it's not necessary to recompile every program 1001638032Speter that does bulk data transfer). 1001738032Speter Allow null defaults on $( ... $) lookups. Problem reported by 1001838032Speter Amir Plivatsky. 1001938032Speter Diagnose crufty S and V config lines. This resulted from an 1002038032Speter observation that some people were using the SITE macro 1002138032Speter without the SITECONFIG macro first, which was causing 1002238032Speter bogus config files that were not caught. 1002338032Speter Fix makemap -f flag to turn off case folding (it was turning it 1002438032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 1002538032Speter Fix a problem that caused multiple error messages to be sent if 1002638032Speter you used "sendmail -t -oem -odb", your system uses fcntl 1002738032Speter locking, and one of the recipient addresses is unknown. 1002838032Speter Reset uid earlier in include() so that recursive .forwards or 1002938032Speter :include:s don't use the wrong uid. 1003038032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 1003138032Speter called, the code to recover the descriptor was broken. 1003238032Speter This sometimes (only sometimes) caused problems with the 1003338032Speter alias file. Fix from Motonori Nakamura. 1003438032Speter Fix a problem that caused aliaswait to go into infinite recursion 1003538032Speter if the @:@ metasymbol wasn't found in the alias file. 1003638032Speter Improve error message on newaliases if database files cannot be 1003738032Speter opened or if running with no database format defined. 1003838032Speter Do a better estimation of the size of error messages when NoReturn 1003938032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 1004038032Speter Fix a problem causing the "c" option (don't connect to expensive 1004138032Speter mailers) to be ignored in SMTP. Problem noted and the 1004238032Speter solution suggested by Robert Elz of The University of 1004338032Speter Melbourne. 1004438032Speter Improve connection caching algorithm by passing "[host]" to 1004538032Speter hostsignature, which strips the square brackets and 1004638032Speter returns the real name. This allows mailertable entries 1004738032Speter to match regular entries. 1004838032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 1004938032Speter feature, even if it doesn't work right. 1005038032Speter Catch and log attempts to try the "wiz" command in server SMTP. 1005138032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 1005238032Speter Be more generous at assigning $z to the home directory -- do this 1005338032Speter for programs that are specified through a .forward file. 1005438032Speter Fix from Andrew Chang of Sun Microsystems. 1005538032Speter Always save a fatal error message in preference to a non-fatal 1005638032Speter error message so that the "subject" line of return 1005738032Speter messages is the best possible. 1005838032Speter CONFIG: reduce the number of quotes needed to quote configuration 1005938032Speter parameters with commas: two quotes should work now, e.g., 1006038032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 1006138032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 1006238032Speter connections (domain-ized UUCP). 1006338032Speter CONFIG: fix bug in default maps (-o must be before database file 1006464562Sgshapiro name). Pointed out by Christophe Wolfhugel. 1006538032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 1006638032Speter DNS. This would presumably be used in UUCP islands. 1006738032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 1006838032Speter CONFIG: log $u in Received: line. This is in technical violation 1006938032Speter of the standards, since it doesn't guarantee a domain 1007038032Speter on the address. 1007138032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 1007238032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 1007338032Speter the "m" flag should you want it. Apparently some Solaris 2.2 1007438032Speter installations can't handle multiple local recipients. 1007538032Speter Problem noted by Josh Smith. 1007638032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 1007738032Speter CONFIG: change default version level from 4 to 5. 1007838032Speter CONFIG: add FEATURE(nullclient) to create a config file that 1007938032Speter forwards all mail to a hub without ever looking at the 1008038032Speter addresses in any detail. 1008138032Speter CONFIG: properly strip mailer: information off of relays when 1008238032Speter used to change .BITNET form into %-hack form. 1008338032Speter CONFIG: fix a problem that caused infinite loops if presented 1008438032Speter with an address such as "!foo". 1008538032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 1008638032Speter the reverse "PTR" mapping is broken. There's a better 1008738032Speter way to do this, but the change is fairly major and I 1008838032Speter want to hold it for another release. Problem noted by 1008938032Speter Bret Marquis. 1009038032Speter 1009164562Sgshapiro8.5/8.5 1993/07/23 1009238032Speter Serious bug: if you used a command line recipient that was unknown 1009338032Speter sendmail would not send a return message (it was treating 1009438032Speter everything as though it had an SMTP-style client that 1009538032Speter would do the return itself). Problem noted by Josh Smith. 1009638032Speter Change "trymx" option in getcanonname() to ignore all MX data, 1009738032Speter even during a T_ANY query. This actually didn't break 1009838032Speter anything, because the only time you called getcanonname 1009938032Speter with !trymx was if you already knew there were no MX 1010038032Speter records, but it is somewhat cleaner. From Motonori 1010138032Speter Nakamura. 1010238032Speter Don't call getcanonname from getmxrr if you already know there 1010338032Speter are no DNS records matching the name. 1010438032Speter Fix a problem causing error messages to always include "The 1010538032Speter original message was received ... from localhost". 1010638032Speter The correct original host information is now included. 1010738032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 1010838032Speter version of "test" doesn't have the -x flag). Change it 1010938032Speter to use -f instead. From John Myers. 1011038032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 1011138032Speter esmtp -- it should be smtp. 1011238032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 1011338032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 1011438032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 1011538032Speter this cleans up the configs somewhat. This fixes a serious 1011638032Speter problem that caused route-addrs to get mistaken as relays, 1011738032Speter pointed out by John Myers. WARNING: this also causes 1011838032Speter the default on SMART_HOST to change from "suucp" to 1011938032Speter "relay" if you have MAILER(smtp) specified. 1012038032Speter 1012164562Sgshapiro8.4/8.4 1993/07/22 1012238032Speter Add option `w'. If you receive a message that comes to you because 1012338032Speter you are the best (lowest preference) target of an MX, and 1012438032Speter you haven't explicitly recognized the source MX host in 1012538032Speter your .cf file, this option will cause you to try the target 1012638032Speter host directly (as if there were no MX for it at all). If 1012738032Speter `w' is not set, this case is a configuration error. 1012838032Speter Beware: if `w' is set, senders may get bogus errors like 1012938032Speter "message timed out" or "host unknown" for problems that 1013038032Speter are really configuration errors. This option is 1013138032Speter disrecommended, provided only for compatibility with 1013238032Speter UIUC sendmail. 1013338032Speter Fix a problem that caused the incoming socket to be left open 1013438032Speter when sendmail forks after the DATA command. This caused 1013538032Speter calling systems to wait in FIN_WAIT_2 state until the 1013638032Speter entire list was processed and the child closed -- a 1013738032Speter potentially prodigious amount of time. Problem noted 1013838032Speter by Neil Rickert. 1013938032Speter Fix problem (created in 6.64) that caused mail sent to multiple 1014038032Speter addresses, one of which was a bad address, to completely 1014138032Speter suppress the sending of the message. This changes 1014238032Speter handling of EF_FATALERRS somewhat, and adds an 1014338032Speter EF_GLOBALERRS flag. This also fixes a potential problem 1014438032Speter with duplicate error messages if there is a syntax error 1014538032Speter in the header of a message that isn't noticed until late 1014638032Speter in processing. Original problem pointed out by Josh Smith 1014738032Speter of Harvey Mudd College. This release includes quite a bit 1014838032Speter of dickering with error handling (see below). 1014938032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 1015038032Speter will only hurt already-broken software and should help 1015138032Speter humans. 1015238032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 1015338032Speter compiled in. It would never read the alias file. 1015438032Speter Repair unbalanced `)' and `>' (the "open" versions are already 1015538032Speter repaired). 1015638032Speter Logging of "done" in dropenvelope() was incorrect: it would 1015738032Speter log this even when the queue file still existed. Change 1015838032Speter this to only log "done" (at log level 11) when the 1015938032Speter queue file is actually removed. From John Myers. 1016038032Speter Log "lost connection" in server SMTP at log level 20 if there 1016138032Speter is no pending transaction. Some senders just close the 1016238032Speter connection rather than sending QUIT. 1016338032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 1016438032Speter domains that do not have MX records -- this would cause 1016538032Speter the subsequent host name lookup to fail. The problem 1016638032Speter only occurred if you had FEATURE(nocanonify) set. 1016738032Speter Problem noted by Rick McCarty of Texas Instruments. 1016838032Speter Fix invocation of setvbuf when passed a -X flag -- I had 1016938032Speter unwittingly used an ANSI C extension, and this caused 1017038032Speter core dumps on some machines. 1017138032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 1017238032Speter Previously it just gave an empty send queue, which 1017338032Speter then gave either "Need RCPT (recipient)" at the DATA 1017438032Speter (confusing, since you had given an RCPT command which 1017538032Speter returned 250) or just dropped the email, depending on 1017638032Speter whether you were running VERBose mode. Now it usually 1017738032Speter diagnoses this case as "aliasing/forwarding loop broken". 1017838032Speter Unfortunately, it still doesn't adequately diagnose 1017938032Speter some true error conditions. 1018038032Speter Add internal concept of "warning messages" using 6xx codes. 1018138032Speter These are not reported only to Postmaster. Unbalanced 1018238032Speter parens, brackets, and quotes are printed as 653 codes. 1018338032Speter They are always mapped to 5xx codes before use in SMTP. 1018438032Speter Clean up error messages to tell both the actual address that 1018538032Speter failed and the alias they arose from. This makes it 1018638032Speter somewhat easier to diagnose problems. Difficulty noted 1018738032Speter by Motonori Nakamura. 1018838032Speter Fix a problem that inappropriately added a ctladdr to addresses 1018938032Speter that shouldn't have had one during a queue run. This 1019038032Speter caused error messages to be handled differently during 1019138032Speter a queue run than a direct run. 1019238032Speter Don't print the qf name and line number if you get errors during 1019338032Speter the direct run of the queue from srvrsmtp -- this was 1019438032Speter just extra stuff for users to crawl through. 1019538032Speter Put command line flags on second line of pid file so you can 1019638032Speter auto-restart the daemon with all appropriate arguments. 1019738032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1019838032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1019938032Speter restart it. 1020038032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1020138032Speter IDENT daemon to screw up. This required that I change 1020238032Speter HASSETEUID to HASSETREUID and complicate the mode 1020338032Speter changing somewhat because both Ultrix and SunOS seem 1020438032Speter to have a bug causing seteuid() to set the saved uid 1020538032Speter as well as the effective. The program test/t_setreuid.c 1020638032Speter will test to see if your implementation of setreuid(2) 1020738032Speter is appropriately functional. 1020838032Speter The FallBackMX (option V) handling failed to properly identify 1020938032Speter fallback to yourself -- most of the code was there, 1021038032Speter but it wasn't being enabled. Problem noted by Murray 1021138032Speter Kucherawy of the University of Waterloo. 1021238032Speter Change :include: open timeout from ETIMEDOUT to an internal 1021338032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1021438032Speter with CurHostName" in error messages, which can be 1021538032Speter confusing. Reported by Jonathan Kamens of OpenVision 1021638032Speter Technologies. 1021738032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1021838032Speter process group id. The original fix was to get around 1021938032Speter some problems with recalcitrant MUAs, but it breaks 1022038032Speter any call from a shell that creates a process group id 1022138032Speter different from the process id. I could try to fix 1022238032Speter this by diddling the tty owner (using tcsetpgrp or 1022338032Speter equivalent) but this is too likely to break other 1022438032Speter things. 1022538032Speter Portability changes: 1022638032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1022738032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1022838032Speter instead of using standard flags. Oh joy. This 1022943730Speter behavior reported by Jon Giltner of University 1023038032Speter of Colorado. 1023138032Speter SGI IRIX -- this includes several changes that should 1023238032Speter help other strict ANSI compilers. 1023338032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1023438032Speter Corporation. 1023538032Speter Solaris running the Sun C compiler (which despite the 1023638032Speter documentation apparently doesn't define 1023738032Speter __STDC__ by default). 1023838032Speter ConvexOS from Eric Schnoebelen of Convex. 1023938032Speter Sony NEWS workstations and Omron LUNA workstations from 1024038032Speter Motonori Nakamura. 1024138032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1024238032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1024338032Speter several people have made a good argument that this 1024438032Speter creates more problems than it solves (although this 1024538032Speter may prove painful in the short run). 1024638032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1024738032Speter format. 1024838032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1024938032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1025038032Speter addresses are also passed through this ruleset. 1025138032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1025238032Speter internet-style addresses would "fall off the end" of 1025338032Speter ruleset zero and be interpreted as local -- however, 1025438032Speter the angle brackets confused the recursive call. 1025538032Speter These are now diagnosed as "Unrecognized host name". 1025638032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1025738032Speter ifdef(`_MAILER_USENET_') instead of 1025838032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1025938032Speter of SINTEF RUNIT, Oslo. 1026038032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1026138032Speter early in ruleset 0; this allows .mc authors to bypass 1026238032Speter things like the "short circuit" code for local addresses. 1026338032Speter Prompted by a comment by Bill Wisner of The Well. 1026438032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1026538032Speter esmtp) to send SMTP mail. This allows you to default 1026638032Speter to esmtp but use a mailertable or other override to 1026738032Speter deal with broken servers. This logic was pointed out 1026838032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1026938032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1027038032Speter environments. Ugly as sin. 1027138032Speter 1027264562Sgshapiro8.3/8.3 1993/07/13 1027338032Speter Fix setuid problems introduced in 8.2 that caused messages 1027438032Speter like "Cannot create qfXXXXXX: Invalid argument" 1027538032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1027638032Speter involved a new compile flag "HASSETEUID" that takes 1027738032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1027838032Speter that the POSIX interface is broken enough to break 1027938032Speter some systems badly. This includes some fixes for 1028038032Speter HP-UX. Also fixes problems where the real uid is 1028138032Speter not reset properly on startup (from Neil Rickert). 1028238032Speter Fix a problem that caused timed out messages to not report the 1028338032Speter addresses that timed out. Error messages are also more 1028438032Speter "user friendly". 1028538032Speter Drop required bandwidth on connections from 64 bytes/sec to 1028638032Speter 16 bytes/sec. 1028738032Speter Further Solaris portability changes -- doesn't require the BSD 1028838032Speter compatibility library. This also adds a new 1028938032Speter "HASGETDTABLESIZE" compile flag which can be used if 1029038032Speter you want to use getdtablesize(2) instead of sysconf(2). 1029138032Speter These are loosely based on changes from David Meyer at 1029238032Speter University of Oregon. This now seems to work, at least 1029338032Speter for quick test cases. 1029438032Speter Fix a problem that can cause duplicate error messages to be 1029538032Speter sent if you are in SMTP, you send to multiple addresses, 1029638032Speter and at least one of those addresses is good and points 1029738032Speter to an account that has a .forward file (whew!). 1029838032Speter Fix a problem causing messages to be discarded if checkcompat() 1029938032Speter returned EX_TEMPFAIL (because it didn't properly mark 1030038032Speter the "to" address). Problem noted by John Myers. 1030138032Speter Fix dfopen to return NULL if the open failed; I was depending 1030238032Speter on fdopen(-1) returning NULL, which isn't the case. This 1030338032Speter isn't serious, but does result in weird error diagnoses. 1030438032Speter From Michael Corrigan. 1030538032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1030638032Speter messages sent through UUCP-family mailers. Suggested 1030738032Speter by Bill Wisner of The Well. 1030838032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1030938032Speter include a "uucp-dom" mailer that uses domain-style 1031038032Speter addressing. Suggested by Bill Wisner. 1031138032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1031238032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1031338032Speter Christophe Wolfhugel. 1031438032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1031538032Speter 1031664562Sgshapiro8.2/8.2 1993/07/11 1031738032Speter Don't drop out on config file parse errors in -bt mode. 1031838032Speter On older configuration files, assume option "l" (use Errors-To 1031938032Speter header) for back compatibility. NOTE: this DOES NOT 1032038032Speter imply an endorsement of the Errors-To: header in any way. 1032138032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1032238032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1032338032Speter SMTP server to give an error on this command, and 1032438032Speter logging it in the transcript can be confusing. Fix 1032538032Speter from Bill Wisner. 1032638032Speter IRIX compatibility changes provided by Dan Rich 1032738032Speter <drich@sandman.lerc.nasa.gov>. 1032838032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1032938032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1033038032Speter <juo@klinzhai.rutgers.edu> 1033138032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1033238032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1033338032Speter match the other flags in that file. 1033438032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1033538032Speter Save h_errno in mci struct and improve error message display. 1033638032Speter Changes from Eric Wassenaar. 1033738032Speter Open /dev/null for the transcript if the create of the xf file 1033838032Speter failed; this avoids at least one possible null pointer 1033938032Speter reference in very weird cases. From Eric Wassenaar. 1034038032Speter Clean up statistics gathering; it was over-reporting because of 1034138032Speter forks. From Eric Wassenaar. 1034238032Speter Fix problem that causes old Return-Path: line to override new 1034338032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1034438032Speter re-using old value). From Motonori Nakamura. 1034538032Speter Fix broken -m flag in K definition -- even if -m (match only) 1034638032Speter was specified, it would still replace the key with the 1034738032Speter value. Noted by Rick McCarty of Texas Instruments. 1034838032Speter If the name server timed out over several days, no "timed out" 1034938032Speter message would ever be sent back. The timeout code 1035038032Speter has been moved from markfailure() to dropenvelope() 1035138032Speter so that all such failures should be diagnosed. Pointed 1035238032Speter out by Christophe Wolfhugel and others. 1035338032Speter Relax safefile() constraints: directories in an include or 1035438032Speter forward path must be readable by self if the controlling 1035538032Speter user owns the entry, readable by all otherwise (e.g., 1035638032Speter when reading your .forward file, you have to own and 1035738032Speter have X permission in it; everyone needs X permission in 1035838032Speter the root and directories leading up to your home); 1035938032Speter include files must be readable by anyone, but need not 1036038032Speter be owned by you. 1036138032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1036238032Speter reading a .forward file; this gets around some problems 1036338032Speter on NFS mounts if root permission is not exported and 1036438032Speter the user's home directory isn't x'able. 1036538032Speter Additional NeXT portability enhancements from Axel Zinser. 1036638032Speter Additional HP-UX portability enhancements from Brian Bullen. 1036738032Speter Add a timeout around SMTP message writes; this assumes you can 1036838032Speter get throughput of at least 64 bytes/second. Note that 1036938032Speter this does not impact the "datafinal" default, which 1037038032Speter is separate; this is just intended to work around 1037138032Speter network clogs that will occur before the final dot 1037238032Speter is sent. From Eric Wassenaar. 1037338032Speter Change map code to set the "include null" flag adaptively -- 1037438032Speter it initially tries both, but if it finds anything 1037538032Speter matching without a null it never tries again with a 1037638032Speter null and vice versa. If -N is specified, it never 1037738032Speter tries without the null and creates new maps with a 1037838032Speter null byte. If -O is specified, it never tries with 1037938032Speter the null (for efficiency). If -N and -O are specified, 1038038032Speter you get -NO (get it?) lookup at all, so this would 1038138032Speter be a bad idea. If you don't specify either -N or -O, 1038238032Speter it adapts. 1038338032Speter Fix recognition of "same from address" so that MH submissions 1038438032Speter will insert the appropriate full name information; 1038538032Speter this used to work and got broken somewhere along the 1038638032Speter way. 1038738032Speter Some changes to eliminate some unnecessary SYSERRs in the 1038838032Speter log. For example, if you lost a connection, don't 1038938032Speter bother reporting that fact on the connection you lost. 1039038032Speter Add some "extended debugging" flags to try to track down 1039138032Speter why we get occasional problems with file descriptor 1039238032Speter one being closed when execing a mailer; it seems to 1039338032Speter only happen when there has been another error in the 1039438032Speter same transaction. This requires XDEBUG, defined 1039538032Speter by default in conf.h. 1039638032Speter Add "-X filename" command line flag, which logs both sides of 1039738032Speter all SMTP transactions. This is intended ONLY for 1039838032Speter debugging bad implementations of other mailers; start 1039938032Speter it up, send a message from a mailer that is failing, 1040038032Speter and then kill it off and examine the indicated log. 1040138032Speter This output is not intended to be particularly human 1040238032Speter readable. This also adds the HASSETVBUF compile 1040338032Speter flag, defaulted on if your compiler defines __STDC__. 1040438032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1040538032Speter have a local net that should get direct connects, you 1040638032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1040738032Speter See cf/README for an example. 1040838032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1040938032Speter sites that don't use the -d flag. 1041038032Speter CONFIG: hide recipient addresses as well as sender addresses 1041138032Speter behind $M if FEATURE(allmasquerade) is specified; this 1041238032Speter has been requested by several people, but can break 1041338032Speter local aliases. For example, if you mail to "localalias" 1041438032Speter this will be rewritten as "localalias@masqueradehost"; 1041538032Speter although initial delivery will work, replies will be 1041638032Speter broken. Use it sparingly. 1041738032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1041838032Speter to qualified domains in headers. I believe this is 1041938032Speter largely equivalent to the IDA feature of the same name. 1042038032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1042138032Speter to override the "system name" as your UUCP name -- 1042238032Speter in particular, to use domain-ized UUCP names. From 1042338032Speter Bill Wisner of The Well. 1042438032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1042538032Speter first. This is currently unused in the config files, 1042638032Speter but could be used in a mailertable entry. 1042738032Speter 1042864562Sgshapiro8.1C/8.1B 1993/06/27 1042938032Speter Serious security bug fix: it was possible to read any file on 1043038032Speter the system, regardless of ownership and permissions. 1043138032Speter If a subroutine returns a fully qualified address, return it 1043238032Speter immediately instead of feeding it back into rewriting. 1043338032Speter This fixes a problem with mailertable lookups. 1043438032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1043538032Speter 1043664562Sgshapiro8.1B/8.1A 1993/06/12 1043738032Speter Serious bug fix: pattern matching backup algorithm stepped by 1043838032Speter two tokens in classes instead of one. Found by Claus 1043938032Speter Assmann at University of Kiel, Germany. 1044038032Speter 1044164562Sgshapiro8.1A/8.1A 1993/06/08 1044238032Speter Another mailertable fix.... 1044338032Speter 1044464562Sgshapiro8.1/8.1 1993/06/07 1044538032Speter 4.4BSD freeze.
