138032Speter SENDMAIL RELEASE NOTES 2157001Sgshapiro $Id: RELEASE_NOTES,v 8.1709 2005/01/12 04:32:31 ca Exp $ 338032Speter 438032Speter 538032SpeterThis listing shows the version of the sendmail binary, the version 638032Speterof the sendmail configuration files, the date of release, and a 738032Spetersummary of the changes in that release. 838032Speter 9157001Sgshapiro8.13.3/8.13.3 2005/01/11 10157001Sgshapiro Enhance handling of I/O errors, especially EOF, when STARTTLS 11157001Sgshapiro is active. 12157001Sgshapiro Make sure a connection is not reused after it has been closed 13157001Sgshapiro due to a 421 error. Problem found by Allan E Johannesen 14157001Sgshapiro of Worcester Polytechnic Institute. 15157001Sgshapiro Avoid triggering an assertion when sendmail is interrupted while 16157001Sgshapiro closing a connection. Problem found by Allan E Johannesen 17157001Sgshapiro of Worcester Polytechnic Institute. 18157001Sgshapiro Regression: a change in 8.13.2 caused sendmail not to try the 19157001Sgshapiro next MX host (or FallbackMXhost if configured) when, at 20157001Sgshapiro connection open, the current server returns a 4xy or 5xy 21157001Sgshapiro SMTP reply code. Problem noted by Mark Tranchant. 22157001Sgshapiro 23157001Sgshapiro8.13.2/8.13.2 2004/12/15 24157001Sgshapiro Do not split the first header even if it exceeds the internal 25157001Sgshapiro buffer size. Previously a part of such a header would 26157001Sgshapiro end up in the body of the message. Problem noted by 27157001Sgshapiro Simple Nomad of BindView. 28157001Sgshapiro Do not complain about "cataddr: string too long" when checking 29157001Sgshapiro headers that do not contain RFC 2822 addresses. 30157001Sgshapiro Problem noted by Rich Graves of Brandeis University. 31157001Sgshapiro If a server returns a 421 reply to the RSET command between 32157001Sgshapiro message deliveries, do not attempt to deliver any more 33157001Sgshapiro messages on that connection. This prevents bogus "Bad 34157001Sgshapiro file number" recipient status. Problem noted by 35157001Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 36157001Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 37157001Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 38157001Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 39157001Sgshapiro for data exchanges than the value used by sendmail, e.g., 40157001Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 41157001Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 42157001Sgshapiro them off at a comma. Problem noted by Krzysztof Oledzki. 43157001Sgshapiro Add more logging to milter change header functions to 44157001Sgshapiro complement existing logging. Based on patch from 45157001Sgshapiro Gurusamy Sarathy of Active State. 46157001Sgshapiro Include <lber.h> in include/sm/config.h when LDAPMAP is defined. 47157001Sgshapiro Patch from Edgar Hoch of the University of Stuttgart. 48157001Sgshapiro Fix DNS lookup if IPv6 is enabled when converting an IP address 49157001Sgshapiro to a hostname for use with SASL. Problem noted by Ken Jones; 50157001Sgshapiro patch from Hajimu UMEMOTO. 51157001Sgshapiro CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog 52157001Sgshapiro mailer. Patch from John Beck of Sun Microsystems. 53157001Sgshapiro LIBMILTER: It was possible that xxfi_abort() was called after 54157001Sgshapiro xxfi_eom() for a message if some timeouts were triggered. 55157001Sgshapiro Patch from Alexey Kravchuk. 56157001Sgshapiro LIBMILTER: Slightly rearrange mutex use in listener.c to allow 57157001Sgshapiro different threads to call smfi_opensocket() and smfi_main(). 58157001Sgshapiro Patch from Jordan Ritter of Cloudmark. 59157001Sgshapiro MAIL.LOCAL: Properly terminate MBDB before exiting. Problem 60157001Sgshapiro noted by Nelson Fung. 61157001Sgshapiro MAIL.LOCAL: make strip-mail.local used a wrong path to access 62157001Sgshapiro mail.local. Problem noted by William Park. 63157001Sgshapiro VACATION: Properly terminate MBDB before exiting. Problem noted 64157001Sgshapiro by Nelson Fung. 65157001Sgshapiro Portability: 66157001Sgshapiro Add support for DragonFly BSD. 67157001Sgshapiro New Files: 68157001Sgshapiro cf/ostype/dragonfly.m4 69157001Sgshapiro devtools/OS/DragonFly 70157001Sgshapiro include/sm/os/sm_os_dragonfly.h 71157001Sgshapiro Deleted Files: 72157001Sgshapiro libsm/vsscanf.c 73157001Sgshapiro 74157001Sgshapiro8.13.1/8.13.1 2004/07/30 75157001Sgshapiro Using the default AliasFile ldap: specification would cause the 76157001Sgshapiro objectClasses of the LDAP response to be included in the 77157001Sgshapiro alias expansion. Problem noted by Brenden Conte of 78157001Sgshapiro Rensselaer Polytechnic Institute. 79157001Sgshapiro Fix support for a fallback smart host for system where DNS is 80157001Sgshapiro (partially) available. From John Beck of Sun Microsystems. 81157001Sgshapiro Fix SuperSafe=PostMilter behavior when a milter replaces a body 82157001Sgshapiro but the data file is not yet stored on disk because it is 83157001Sgshapiro smaller than the size of the memory buffer. Problem noted 84157001Sgshapiro by David Russell. 85157001Sgshapiro Fix certificate revocation list support; if a CRL was specified 86157001Sgshapiro but the other side presented a cert that was signed by 87157001Sgshapiro a different (trusted) CA than the one which issued the CRL, 88157001Sgshapiro verification would always fail. Problem noted by Al Smith. 89157001Sgshapiro Run mailer programs as the RunAsUser when RunAsUser is set and 90157001Sgshapiro the F=S mailer flag is set without a U= mailer equate. 91157001Sgshapiro Problem noted by John Gardiner Myers of Proofpoint. 92157001Sgshapiro ${nbadrcpts} was off by one if BadRcptThrottle is zero. 93157001Sgshapiro Patch from Sung-hoon Choi of DreamWiz Inc. 94157001Sgshapiro CONFIG: Emit a warning if FEATURE(`access_db') is used after 95157001Sgshapiro FEATURE(`greet_pause') because then the latter will not 96157001Sgshapiro use the access map. Note: if no default value is given 97157001Sgshapiro for FEATURE(`greet_pause') then it issues an error if 98157001Sgshapiro FEATURE(`access_db') is not specified before it. 99157001Sgshapiro Problem noted by Alexander Dalloz of University of 100157001Sgshapiro Bielefeld. 101157001Sgshapiro CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause') 102157001Sgshapiro is used to give more flexibility for local changes. 103157001Sgshapiro Portability: 104157001Sgshapiro Fix a 64 bit problem in the socket map code. Problem 105157001Sgshapiro noted by Geoff Adams. 106157001Sgshapiro NetBSD 2.0F has closefrom(3). Patch from Andrew Brown. 107157001Sgshapiro NetBSD can use sysctl(3) to get the number of CPUs in 108157001Sgshapiro a system. Patch from Andrew Brown. 109157001Sgshapiro Add a README file in doc/op/ to explain potential 110157001Sgshapiro incompatibilities with various *roff related 111157001Sgshapiro tools. Problem tracked down by Per Hedeland. 112157001Sgshapiro New Files: 113157001Sgshapiro doc/op/README 114157001Sgshapiro 115157001Sgshapiro8.13.0/8.13.0 2004/06/20 116157001Sgshapiro Do not include AUTH data in a bounce to avoid leaking confidential 117157001Sgshapiro information. See also cf/README about MSP and the section 118147078Sgshapiro "Providing SMTP AUTH Data when sendmail acts as Client". 119147078Sgshapiro Problem noted by Neil Rickert of Northern Illinois 120147078Sgshapiro University. 121147078Sgshapiro Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n 122147078Sgshapiro and -DSM_CONF_SETITIMER=0. Problem noted by Juergen Georgi 123147078Sgshapiro of RUS University of Stuttgart. 124147078Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 125147078Sgshapiro by Christof Haerens, patch from Per Hedeland. 126147078Sgshapiro Add support for LDAP recursion based on types given to attribute 127147078Sgshapiro specifications in an LDAP map definition. This allows 128147078Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 129147078Sgshapiro URL which will in turn be queried. See the ``LDAP 130147078Sgshapiro Recursion'' section of doc/op/op.me for more information. 131147078Sgshapiro Based on patch from Andrew Baucom. 132147078Sgshapiro Extend the default LDAP specifications for AliasFile 133147078Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 134147078Sgshapiro include support for LDAP recursion via new attributes. 135147078Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 136147078Sgshapiro of cf/README for more information. 137147078Sgshapiro New option for LDAP maps: the -w option allows you to specify the 138147078Sgshapiro LDAP API/protocol version to use. The default depends on 139147078Sgshapiro the LDAP library. 140147078Sgshapiro New option for LDAP maps: the -H option allows you to specify an 141147078Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 142147078Sgshapiro and -p port. This also allows for the use of LDAP over 143147078Sgshapiro SSL and connections via named sockets if your LDAP 144147078Sgshapiro library supports it. 145147078Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 146147078Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 147147078Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 148147078Sgshapiro during a SMTP session then terminate it just like it is 149147078Sgshapiro done for too many bad SMTP commands. 150147078Sgshapiro Basic connection rate control support has been added: the daemon 151147078Sgshapiro maintains the number of incoming connections per client 152147078Sgshapiro IP address and total in the macros {client_rate} and 153147078Sgshapiro {total_rate}, respectively. These macros can be used 154147078Sgshapiro in the cf file to impose connection rate limits. 155147078Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 156147078Sgshapiro determines the length of the interval for which the 157147078Sgshapiro number of connections is stored. Based on patch from 158147078Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 159147078Sgshapiro Add optional protection from open proxies and SMTP slammers which 160147078Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 161147078Sgshapiro If enabled by the new ruleset greet_pause (see 162147078Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 163147078Sgshapiro amount of time before sending the initial 220 SMTP 164147078Sgshapiro greeting. If any traffic is received before then, a 554 165147078Sgshapiro SMTP response is sent and all SMTP commands are rejected 166147078Sgshapiro during that connection. 167147078Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 168147078Sgshapiro server could sleep for a very long time. Fix based on 169147078Sgshapiro patch from Tadashi Kobayashi of IIJ. 170147078Sgshapiro Fix a potential memory leak in persistent queue runners if the 171147078Sgshapiro number of entries in the queue exceeds the limit of jobs. 172141858Sgshapiro Problem noted by Steve Hubert of University of Washington. 173141858Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 174141858Sgshapiro misinterpret it as a permanent error. 175141858Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 176141858Sgshapiro all milters accepted the mail. This can increase 177141858Sgshapiro performance if many mails are rejected by milters due to 178141858Sgshapiro body scans. Based on patch from David F. Skoll. 179141858Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 180141858Sgshapiro header, whether provided by the client or generated by 181141858Sgshapiro sendmail. 182141858Sgshapiro New macro {client_connections} which contains the number of open 183141858Sgshapiro connections in the SMTP server for the client IP address. 184141858Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 185141858Sgshapiro Mines de Paris. 186141858Sgshapiro sendmail will now remove its pidfile when it exits. This was done 187141858Sgshapiro to prevent confusion caused by running sendmail stop 188141858Sgshapiro scripts two or more times, where the second and subsequent 189141858Sgshapiro runs would report misleading error messages about sendmail's 190141858Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 191141858Sgshapiro for a discussion of the implications of this, including 192141858Sgshapiro how to correct broken scripts which may have depended on 193141858Sgshapiro the old behavior. From John Beck of Sun Microsystems. 194141858Sgshapiro Support per-daemon input filter lists which override the default 195141858Sgshapiro filter list specified in InputMailFilters. The filters 196141858Sgshapiro can be listed in the I= equate of DaemonPortOptions. 197141858Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 198141858Sgshapiro your configuration relies on this behavior, you have to 199141858Sgshapiro add those names to class 'w' yourself. Problem noted 200141858Sgshapiro by Sander Eerkes. 201141858Sgshapiro Support message quarantining in the mail queue. Quarantined 202141858Sgshapiro messages are not run on normal queue displays or runs 203141858Sgshapiro unless specifically requested with -qQ. Quarantined queue 204141858Sgshapiro files are named with an hf prefix instead of a qf prefix. 205141858Sgshapiro The -q command line option now can specify which queue to display 206141858Sgshapiro or run. -qQ operates on quarantined queue items. -qL 207141858Sgshapiro operates on lost queue items. 208141858Sgshapiro Restricted mail queue runs and displays can be done based on the 209141858Sgshapiro quarantined reason using -qQtext to run or display 210141858Sgshapiro quarantined items if the quarantine reason contains the 211141858Sgshapiro given text. Similarly, -q!Qtext will run or display 212141858Sgshapiro quarantined items which do not have the given text in the 213141858Sgshapiro quarantine reason. 214141858Sgshapiro Items in the queue can be quarantined or unquarantined using the 215141858Sgshapiro new -Q option. See doc/op/op.me for more information. 216141858Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 217141858Sgshapiro quarantine reason is shown in a new line prefixed by 218141858Sgshapiro "QUARANTINE:". 219141858Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 220141858Sgshapiro to quarantine messages in check_* (except check_compat) and 221141858Sgshapiro header check rulesets. The $: of the mailer triplet will 222141858Sgshapiro be used for the quarantine reason. 223141858Sgshapiro Add a new quarantine count to the mailstats collected. 224141858Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 225141858Sgshapiro message if it is quarantined. 226141858Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 227141858Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 228141858Sgshapiro See sendmail/README and doc/op/op.me for details as well as 229141858Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 230141858Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 231141858Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 232141858Sgshapiro lookup for the client IP address. Note: this is the same 233141858Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 234141858Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 235141858Sgshapiro recipients received so far in a transaction. 236141858Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 237132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 238132943Sgshapiro noted by Kai Schlichting. 239132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 240132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 241132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 242132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 243132943Sgshapiro Wolfhugel of France Telecom Oleane. 244132943Sgshapiro Do not silently truncate long strings in address rewriting. 245132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 246132943Sgshapiro Oceana Matrix Ltd. 247132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 248132943Sgshapiro support mutual authentication. From Kenneth Murchison of 249132943Sgshapiro Oceana Matrix Ltd. 250132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 251132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 252132943Sgshapiro format just like the STARTTLS related macros to avoid 253132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 254132943Sgshapiro Masarati of SysNet s.n.c. 255132943Sgshapiro New option AuthRealm to set the authentication realm that is 256132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 257132943Sgshapiro of the University of Manitoba. 258132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 259132943Sgshapiro successful, otherwise relaying would be allowed if 260132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 261132943Sgshapiro is active. 262132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 263132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 264132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 265132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 266132943Sgshapiro DIGEST-MD5 and LOGIN. 267132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 268132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 269132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 270132943Sgshapiro overwrite each other's pid files. 271132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 272132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 273132943Sgshapiro Wolfhugel of France Telecom. 274132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 275132943Sgshapiro LogLevel 12 or higher. 276132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 277132943Sgshapiro try to use the SMTP command VERB to propagate this option 278132943Sgshapiro to the MTA which in turn will show the delivery just like 279132943Sgshapiro it was done before the default 8.12 separation of MSP and 280132943Sgshapiro MTA. Based on patch by Per Hedeland. 281132943Sgshapiro If a daemon is refusing connections for longer than the time specified 282132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 283132943Sgshapiro to high load, log this information. Patch from John Beck 284132943Sgshapiro of Sun Microsystems. 285132943Sgshapiro Remove the ability for non-trusted users to raise the value of 286132943Sgshapiro CheckpointInterval on the command line. 287132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 288132943Sgshapiro subset of the functionality of the 's' flag. 289132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 290132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 291132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 292132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 293132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 294132943Sgshapiro causing subsequent messages to be sent instead of being 295132943Sgshapiro discarded. This also caused milter callbacks to be called 296132943Sgshapiro out of order after the SMTP session was reset. 297132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 298132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 299132943Sgshapiro further information. 300132943Sgshapiro New command line option -D logfile to send debug output to 301132943Sgshapiro the indicated log file instead of stdout. 302132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 303132943Sgshapiro queue return and warning times for delivery status 304132943Sgshapiro notifications. 305132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 306132943Sgshapiro at all. 307132943Sgshapiro Several more return values for ruleset srv_features have been added 308132943Sgshapiro to enable/disable certain features in the server per 309132943Sgshapiro connection. See doc/op/op.me for details. 310132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 311132943Sgshapiro for DaemonPortOptions. 312132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 313132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 314132943Sgshapiro of Northern Illinois University. 315132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 316132943Sgshapiro be tried as a last resort after all other fallbacks. This 317132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 318132943Sgshapiro view of inside the company, but an incomplete view of 319132943Sgshapiro outside). From John Beck of Sun Microsystems. 320132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 321132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 322132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 323132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 324132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 325132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 326132943Sgshapiro of the University of Illinois at Urbana-Champaign. 327132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 328132943Sgshapiro applications for use in the xxfi_eom() callback. 329132943Sgshapiro New macro {time} which contains the output of the time(3) function, 330132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 331132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 332132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 333132943Sgshapiro terminate the SMTP session with a 421 error message. 334132943Sgshapiro Get rid of dead code that tried to access the environment variable 335132943Sgshapiro HOSTALIASES. 336132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 337132943Sgshapiro compile with -DUSE_TTYPATH=1. 338132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 339132943Sgshapiro the header value passed in without balancing quotes, 340132943Sgshapiro parentheses, and angle brackets. Based on patch from 341132943Sgshapiro Oleg Bulyzhin. 342132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 343132943Sgshapiro angle brackets when reading in rulesets. This allows 344132943Sgshapiro rules to be written for header checks to catch strings 345132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 346132943Sgshapiro Based on patch from Oleg Bulyzhin. 347132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 348132943Sgshapiro some temporary errors like ECONNABORTED. 349132943Sgshapiro Added list of CA certificates that are used by members of the 350132943Sgshapiro sendmail consortium, see CACerts. 351132943Sgshapiro Portability: 352141858Sgshapiro Two new compile options have been added: 353132943Sgshapiro HASCLOSEFROM System has closefrom(3). 354132943Sgshapiro HASFDWALK System has fdwalk(3). 355132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 356132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 357132943Sgshapiro change to using fcntl() locking until they can fix 358132943Sgshapiro it. Be sure to update other sendmail related 359132943Sgshapiro programs to match locking techniques. 360132943Sgshapiro New compile time option NEEDINTERRNO which should be set 361132943Sgshapiro if <errno.h> does not declare errno itself. 362132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 363132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 364132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 365132943Sgshapiro Center for Scientific Computing. 366132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 367132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 368132943Sgshapiro Remove path from compiler definition for Interix because 369132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 370132943Sgshapiro Also use <sys/mkdev.h> to get the correct 371132943Sgshapiro major()/minor() definitions. Based on feedback 372132943Sgshapiro from Mark Funkenhauser. 373132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 374132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 375132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 376132943Sgshapiro cf/sendmail.schema for more information. 377132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 378132943Sgshapiro is of the form "user:group" when used for submit.mc. 379132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 380132943Sgshapiro of Northern Illinois University. 381132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 382132943Sgshapiro instructs the check_* (except check_compat) to quarantine 383132943Sgshapiro the message using the given reason. 384132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 385132943Sgshapiro instead of "host" to avoid problem with looking up other 386132943Sgshapiro DNS records than just A. 387132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 388132943Sgshapiro length of the interval for which the number of incoming 389132943Sgshapiro connections is maintained. 390132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 391132943Sgshapiro rate control for individual hosts or nets. 392132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 393132943Sgshapiro number of open SMTP connections for individual hosts or nets. 394132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 395132943Sgshapiro slamming protection described above. The feature can 396132943Sgshapiro take an argument specifying the milliseconds to wait and/or 397132943Sgshapiro use the access database to look the pause time based on 398132943Sgshapiro client hostname, domain, IP address, or subnet. 399132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 400132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 401132943Sgshapiro rejections based on the unverified hostname of client, 402132943Sgshapiro which turns on the same behavior as in earlier sendmail 403132943Sgshapiro versions when delay_checks was not in use. See also entry 404132943Sgshapiro above about check_relay being invoked with ${client_name}. 405132943Sgshapiro CONFIG: New option confREJECT_LOG_INTERVAL to specify the log 406132943Sgshapiro interval when refusing connections for this long. 407132943Sgshapiro CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases 408132943Sgshapiro this requires a change in a mc file. Requested by 409132943Sgshapiro Ted Roberts of Electronic Data Systems. 410132943Sgshapiro CONFIG: New option confAUTH_REALM to set the authentication realm 411132943Sgshapiro that is passed to the Cyrus SASL library. Patch from 412132943Sgshapiro Gary Mills of the University of Manitoba. 413132943Sgshapiro CONFIG: Rename the (internal) classes {tls}/{src} to {Tls}/{Src} 414132943Sgshapiro to follow the naming conventions. 415132943Sgshapiro CONFIG: Add a third optional argument to local_lmtp to specify 416132943Sgshapiro the A= argument. 417132943Sgshapiro CONFIG: Remove the f flag from the default mailer flags of 418132943Sgshapiro local_lmtp. 419132943Sgshapiro CONFIG: New option confREQUIRES_DIR_FSYNC to turn off the compile 420132943Sgshapiro time flag REQUIRES_DIR_FSYNC at runtime. 421132943Sgshapiro CONFIG: New LOCAL_UUCP macro to insert rules into the generated 422132943Sgshapiro cf file at the same place where MAILER(`uucp') inserts 423132943Sgshapiro its rules. 424132943Sgshapiro CONFIG: New options confTO_QUEUERETURN_DSN and confTO_QUEUEWARN_DSN 425132943Sgshapiro to control queue return and warning times for delivery 426132943Sgshapiro status notifications. 427132943Sgshapiro CONFIG: New option confFALLBACK_SMARTHOST to define FallbackSmartHost. 428132943Sgshapiro CONFIG: Add the mc file which has been used to create the cf 429132943Sgshapiro file to the end of the cf file when using make in cf/cf/. 430132943Sgshapiro Patch from Richard Rognlie. 431132943Sgshapiro CONFIG: FEATURE(nodns) has been removed, it was a no-op since 8.9. 432132943Sgshapiro Use ServiceSwitchFile to turn off DNS lookups, see 433132943Sgshapiro doc/op/op.me. 434132943Sgshapiro CONFIG: New option confMILTER_MACROS_EOM (sendmail Milter.macros.eom 435132943Sgshapiro option) defines macros to be sent to milter applications for 436132943Sgshapiro use in the xxfi_eom() callback. 437132943Sgshapiro CONFIG: New option confCRL to specify file which contains 438132943Sgshapiro certificate revocations lists. 439132943Sgshapiro CONFIG: Add a new value (sendertoo) for the third argument to 440132943Sgshapiro FEATURE(`ldap_routing') which will reject the SMTP 441132943Sgshapiro MAIL From: command if the sender address doesn't exist 442132943Sgshapiro in LDAP. See cf/README for more information. 443132943Sgshapiro CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which 444132943Sgshapiro instructs the rulesets on whether or not to do a domain 445132943Sgshapiro lookup if a full address lookup doesn't match. See cf/README 446132943Sgshapiro for more information. 447132943Sgshapiro CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which 448132943Sgshapiro instructs the rulesets on whether or not to queue the mail 449132943Sgshapiro or give an SMTP temporary error if the LDAP server can't be 450132943Sgshapiro reached. See cf/README for more information. Based on 451132943Sgshapiro patch from Billy Ray Miller of Caterpillar. 452132943Sgshapiro CONFIG: Experimental support for MTAMark, see cf/README for details. 453132943Sgshapiro CONFIG: New option confMESSAGEID_HEADER to define a different 454132943Sgshapiro Message-Id: header format. Patch from Bastiaan Bakker 455132943Sgshapiro of LifeLine Networks. 456132943Sgshapiro CONTRIB: New version of cidrexpand which uses Net::CIDR. From 457132943Sgshapiro Derek J. Balling. 458132943Sgshapiro CONTRIB: oldbind.compat.c has been removed due to security problems. 459132943Sgshapiro Found by code inspection done by Reasoning, Inc. 460132943Sgshapiro DEVTOOLS: Add an example file for devtools/Site/, contributed 461132943Sgshapiro by Neil Rickert of Northern Illinois University. 462132943Sgshapiro LIBMILTER: Add new function smfi_quarantine() which allows the 463132943Sgshapiro filter's EOM routine to quarantine the current message. 464132943Sgshapiro Filters which use this function must include the 465132943Sgshapiro SMFIF_QUARANTINE flag in the registered smfiDesc structure. 466132943Sgshapiro LIBMILTER: If a milter sets the reply code to "421", the SMTP server 467132943Sgshapiro will terminate the SMTP session with that error. 468132943Sgshapiro LIBMILTER: Upon filter shutdown, libmilter will not remove a 469132943Sgshapiro named socket in the file system if it is running as root. 470132943Sgshapiro LIBMILTER: Add new function smfi_progress() which allows the filter 471132943Sgshapiro to notify the MTA that an EOM operation is still in progress, 472132943Sgshapiro resetting the timeout. 473132943Sgshapiro LIBMILTER: Add new function smfi_opensocket() which allows the filter 474132943Sgshapiro to attempt to establish the interface socket, and detect 475132943Sgshapiro failure to do so before calling smfi_main(). 476132943Sgshapiro LIBMILTER: Add new function smfi_setmlreply() which allows the 477132943Sgshapiro filter to return a multi-line SMTP reply. 478132943Sgshapiro LIBMILTER: Deal with more temporary errors in accept() by ignoring 479132943Sgshapiro them instead of stopping after too many occurred. 480132943Sgshapiro Suggested by James Carlson of Sun Microsystems. 481132943Sgshapiro LIBMILTER: Fix a descriptor leak in the sample program found in 482132943Sgshapiro docs/sample.html.

If you have an example of improper 566132943Sgshapiro 7 to 8 bit conversion please send it to us. 567132943Sgshapiro Return normal error code for unknown SMTP commands instead of 568132943Sgshapiro the one specified by check_relay or a milter for a 569132943Sgshapiro connection. Problem noted by Andrzej Filip. 570132943Sgshapiro Some ident responses contain data after the terminating CRLF which 571132943Sgshapiro causes sendmail to log "POSSIBLE ATTACK...newline in string". 572132943Sgshapiro To avoid this everything after LF is ignored. 573132943Sgshapiro If the operating system supports O_EXLOCK and HASFLOCK is set 574132943Sgshapiro then a possible race condition for creating qf files 575132943Sgshapiro can be avoided. Note: the race condition does not 576132943Sgshapiro exist within sendmail, but between sendmail and an 577132943Sgshapiro external application that accesses qf files. 578132943Sgshapiro Log the proper options name for TLS related mising files for 579132943Sgshapiro the CACertPath, CACertFile, and DHParameters options. 580132943Sgshapiro Do not split an envelope if it will be discarded, otherwise df 581132943Sgshapiro files could be left behind.

In previous versions this could cause mail 1045102528Sgshapiro not to be delivered if a queue file is repeatedly moved 1046102528Sgshapiro by an external process whenever sendmail moved it back 1047102528Sgshapiro into the right place. Some precautions have been taken 1048102528Sgshapiro to avoid moving queue files if not really necessary. 1049102528Sgshapiro sendmail may use links to refer to queue files and it 1050102528Sgshapiro may store the path of data files in queue files. Hence 1051102528Sgshapiro queue files should not be moved unless those internals 1052102528Sgshapiro are understood and the integrity of the files is not 1053102528Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 1054102528Sgshapiro University. 1055102528Sgshapiro If an error mail is created, and the mail is split across different 1056102528Sgshapiro queue directories, and SuperSafe is off, then write the mail 1057102528Sgshapiro to disk before splitting it, otherwise an assertion is 1058102528Sgshapiro triggered.

Problem noted by Bradley Watts of AT&T Canada. 113398121Sgshapiro Do not try to send a second SMTP QUIT command if the remote 113498121Sgshapiro responds to a MAIL command with a 421 reply or on I/O 113598121Sgshapiro errors. By doing so, the host was marked as having a 113698121Sgshapiro temporary problem and other mail destined for that host was 113798121Sgshapiro queued for the next queue run. Problem noted by Fletcher 113898121Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 113998121Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 114098121Sgshapiro and Neil Rickert of Northern Illinois University. 114198121Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 114298121Sgshapiro which drop the connection instead of responding to the 114398121Sgshapiro command). 114498121Sgshapiro Portability: 114598121Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 114698121Sgshapiro available. 114798121Sgshapiro Define HPUX10 when building on HP-UX 10.X.

Patch from Andrzej Filip. 116998121Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 117098121Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 117198121Sgshapiro This will only have an effect if a parameter is specified, 117298121Sgshapiro i.e., an MX lookup will be performed on the hostname unless 117398121Sgshapiro it is embedded in square brackets. Problem noted by 117498121Sgshapiro Theo Van Dinter of Collective Technologies. 117598121Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 117698121Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 117798121Sgshapiro to allow for the proper time zone on systems where the 117898121Sgshapiro default results in misleading time stamps. That is, syslog 117998121Sgshapiro time stamps and Date headers on submitted mail will use the 118098121Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 118198121Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 118298121Sgshapiro by Neil Rickert of Northern Illinois University. 118398121Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 118498121Sgshapiro binary.

Problem noted by Kari Hurtta 124194334Sgshapiro of the Finnish Meteorological Institute. 124294334Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 124394334Sgshapiro needs to collect children status to avoid zombie processes. 124494334Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 124594334Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 124694334Sgshapiro commands are issued. This makes it consistent with normal 124794334Sgshapiro SMTP connections. 124894334Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 124994334Sgshapiro William D. Colburn of the New Mexico Institute of Mining 125094334Sgshapiro and Technology. 125194334Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 125294334Sgshapiro message sender if the sender had used a deprecated RFC822 125394334Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 125494334Sgshapiro Meteorological Institute. 125594334Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 125694334Sgshapiro parsing. Problem noted by Jorg Bielak from Coastal Web 125794334Sgshapiro Online. 125894334Sgshapiro For systems on which stat(2) does not return a value for st_blksize 125994334Sgshapiro that is the "optimal blocksize for I/O" three new compile 126094334Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 126194334Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 126294334Sgshapiro regular files, and a lower and upper limit for other file 126394334Sgshapiro types, respectively. 126494334Sgshapiro Fix a potential deadlock if two events are supposed to occur at 126594334Sgshapiro exactly the same time.

Problem noted by Bjoern Voigt of TU Berlin. 128394334Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 128494334Sgshapiro server gets stuck while processing that command. Problem 128594334Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 128694334Sgshapiro In addition to printing errors when parsing recipients during 128794334Sgshapiro command line invocations log them to make it simpler 128894334Sgshapiro to understand possible DSNs to postmaster. 128994334Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 129094334Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 129194334Sgshapiro instead of forcing localhost. 129294334Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 129394334Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 129494334Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 129594334Sgshapiro noted by Neil Rickert of Northern Illinois University. 129694334Sgshapiro If a remote server violates the SMTP standard by unexpectedly 129794334Sgshapiro dropping the connection during an SMTP transaction, stop 129894334Sgshapiro sending commands. This prevents bogus "Bad file number" 129994334Sgshapiro recipient status. Problem noted by Allan E Johannesen of 130094334Sgshapiro Worcester Polytechnic Institute. 130194334Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 130294334Sgshapiro almost always too small; do not guess the size at all. 130394334Sgshapiro New VENDOR_DEC for Compaq/DEC.

Problem 138194334Sgshapiro found by Michal Zalewski. 138294334Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 138394334Sgshapiro privileges by disabling debugging (command line -d flag) 138490792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 138590792Sgshapiro used. Suggested by Michal Zalewski. 138690792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 138790792Sgshapiro Problem found by Michal Zalewski. 138890792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 138990792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 139090792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 139190792Sgshapiro If debugging is turned on (-d0.10) print not just the default 139290792Sgshapiro values for configuration file and pid file but also the 139390792Sgshapiro selected values. Problem noted by Brad Chapman. 139490792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 139590792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 139690792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 139790792Sgshapiro this only applied to hostname canonification. Problem 139890792Sgshapiro noted by Bill Fenner of AT&T Research. 139990792Sgshapiro Ignore comments in NIS host records when trying to find the 140090792Sgshapiro canonical name for a host. 140190792Sgshapiro When sendmail has extra privileges, limit mail submission command 140290792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 140390792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.).

You need to create a new user and 144690792Sgshapiro a new group before installing sendmail (both called smmsp by 144790792Sgshapiro default). The installation process tries to install 144890792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 144990792Sgshapiro default.

Suggested 146090792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 146190792Sgshapiro (IdS). 146290792Sgshapiro Fixed problem of a global variable being used for a timeout jump 146390792Sgshapiro point where the variable could become overused for more than 146490792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 146590792Sgshapiro a corrupted stack causing a core dump. The timeout is now 146690792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 146790792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 146890792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 146990792Sgshapiro checks (group ID of RunAsUser). This allows use of a 147090792Sgshapiro set-group-ID sendmail binary for initial message submission 147190792Sgshapiro and no set-user-ID root sendmail is needed. For details 147290792Sgshapiro see sendmail/SECURITY. 147390792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 147490792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 147590792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 147690792Sgshapiro with a fallback of sendmail.cf as configuration file. See 147790792Sgshapiro sendmail/SECURITY. 147890792Sgshapiro New configuration file option UseMSP to allow group writable queue 147990792Sgshapiro files if the group is the same as that of a set-group-ID 148090792Sgshapiro sendmail binary. See sendmail/SECURITY. 148190792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 148290792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 148390792Sgshapiro is sendmail.cf (to be backward compatible). This selection 148490792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 148590792Sgshapiro file: client or mta). See sendmail/SECURITY. 148690792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 148790792Sgshapiro command has been removed. 148890792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 148990792Sgshapiro at compile time or per host (ruleset). 149090792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 149190792Sgshapiro used to look up local mail recipients; the default value 149290792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 149390792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 149490792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 149590792Sgshapiro long, to accomodate envelope splitting. File systems with 149690792Sgshapiro a 14 character file name length limit are no longer 149790792Sgshapiro supported. 149890792Sgshapiro Recipient list used for delivery now gets internally ordered by 149990792Sgshapiro hostsignature (character string version of MX RR). This orders 150090792Sgshapiro recipients for the same MX RR's together meaning smaller 150190792Sgshapiro portions of the list need to be scanned (instead of the whole 150290792Sgshapiro list) each delivery() pass to determine piggybacking. The 150390792Sgshapiro significance of the change is better the larger the recipient 150490792Sgshapiro list. Hostsignature is now created during recipient list 150590792Sgshapiro creation rather than just before delivery. 150690792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 150790792Sgshapiro piggybacking (called coincidental) extended to coattail 150890792Sgshapiro piggybacking. Rather than complete MX RR matching 150990792Sgshapiro (coincidental) piggybacking is done if just the lowest value 151090792Sgshapiro preference matches (coattail). 151190792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 151290792Sgshapiro try other MX hosts if available. 151390792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 151490792Sgshapiro outgoing (client-side) SMTP Authentication. 151590792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 151690792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 151790792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 151890792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 151990792Sgshapiro A new ruleset authinfo can be used to return client side 152090792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 152190792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 152290792Sgshapiro removed in future versions. 152390792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 152490792Sgshapiro requires 334. Mercury 1.48 is a known offender. 152590792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 152690792Sgshapiro for the security layer in SMTP AUTH (SASL). See 152790792Sgshapiro doc/op/op.me for details. 152890792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 152990792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 153090792Sgshapiro signed the presented certificate, the CN and the MD5 hash 153190792Sgshapiro of the presented certificate, respectively. 153290792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 153390792Sgshapiro New ruleset srv_features to enable/disable certain features in the 153490792Sgshapiro server per connection. See doc/op/op.me for details. 153590792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 153690792Sgshapiro recipient; useful to decide whether a conection is secure 153790792Sgshapiro enough on a per recipient basis. 153890792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 153990792Sgshapiro for STARTTLS. 154090792Sgshapiro If no certificate has been requested, the macro {verify} has the 154190792Sgshapiro value "NOT". 154290792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 154390792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 154490792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 154590792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 154690792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 154790792Sgshapiro really required. This change results in a noticable 154890792Sgshapiro performance gains on most machines. Moreover, if shared 154990792Sgshapiro memory is in use, reuse the key several times. 155090792Sgshapiro Add queue groups which can be used to group queue directories with 155190792Sgshapiro the same behavior together. See doc/op/op.me for details. 155290792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 155390792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 155490792Sgshapiro are initially sorted which may result in faster envelope 155590792Sgshapiro splitting. If the mail is submitted directly from the 155690792Sgshapiro command line, then the value also limits the number of 155790792Sgshapiro processes to deliver the envelopes; if more envelopes are 155890792Sgshapiro created they are only queued up and must be taken care of 155990792Sgshapiro by a queue run. 156090792Sgshapiro The check for 'enough disk space' now pays attention to which file 156190792Sgshapiro system each queue directory resides in. 156290792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 156390792Sgshapiro New option QueueFileMode for the default permissions of queue files. 156490792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 156590792Sgshapiro group (one or more queues in a multi-queue environment 156690792Sgshapiro collected together) to process the same work list at the 156790792Sgshapiro same time. 156890792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 156990792Sgshapiro active queue runner processes. 157090792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 157190792Sgshapiro runners per queue group. 157290792Sgshapiro Queue member selection by substring pattern matching now allows 157390792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 157490792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 157590792Sgshapiro of the queue that match during processing. 157690792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 157790792Sgshapiro periodically forking a child to process the queue, a single 157890792Sgshapiro child is forked for each queue that sleeps between queue 157990792Sgshapiro runs. A SIGHUP signal can be sent to restart this 158090792Sgshapiro persistent queue runner. 158190792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 158290792Sgshapiro sendmail process which only runs the queue at an interval: 158390792Sgshapiro sendmail -q15m). 158490792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 158590792Sgshapiro Proposed by Thom O'Connor. 158690792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 158790792Sgshapiro unless the new -qf option or -v is used. 158890792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 158990792Sgshapiro several queue runners are started by hand to avoid contention. 159090792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 159190792Sgshapiro of the qf file (older entries first). 159290792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 159390792Sgshapiro a client to specify an amount of time within which an e-mail 159490792Sgshapiro should be delivered. New option DeliverByMin added to set the 159590792Sgshapiro minimum amount of time or disable the extension. 159690792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 159790792Sgshapiro not allowed unless escaped or quoted. 159890792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 159990792Sgshapiro by Leif Johansson of Stockholm University, which was based on 160090792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 160190792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 160290792Sgshapiro Technology, Stockholm, Sweden. 160390792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 160490792Sgshapiro behavior (no MX lookups), put the name in square brackets. 160590792Sgshapiro Proposed by Thom O'Connor. 160690792Sgshapiro Use shared memory to store free space of filesystems that are used 160790792Sgshapiro for queues, if shared memory is available and if a key is set 160890792Sgshapiro via SharedMemoryKey. This minimizes the number of system 160990792Sgshapiro calls to check the available space. See doc/op/op.me for 161090792Sgshapiro details. 161190792Sgshapiro If shared memory is compiled in the option -bP can be used to print 161290792Sgshapiro the number of entries in the queue(s). 161390792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 161490792Sgshapiro and the usual documentation for details. 161590792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 161690792Sgshapiro Remove '-U' (initial user submission) command line option as 161790792Sgshapiro announced in 8.10. 161890792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 161990792Sgshapiro New macro {addr_type} which contains whether the current address is 162090792Sgshapiro an envelope sender or recipient address. Suggested by 162190792Sgshapiro Neil Rickert of Northern Illinois University. 162290792Sgshapiro Two new options for host maps: -d (retransmission timeout), 162390792Sgshapiro -r (number of retries). 162490792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 162590792Sgshapiro separator such that a lookup can return both an attribute 162690792Sgshapiro and value separated by the given separator. 162790792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 162890792Sgshapiro to map class arith. 162990792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 163090792Sgshapiro (errors that occur when sending an error message) are dropped. 163190792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 163290792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 163390792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 163490792Sgshapiro requirements for files containing secret keys. This is 163590792Sgshapiro necessary for the MSP if client authentification is used. 163690792Sgshapiro Properly handle quoted filenames for class files (to allow for 163790792Sgshapiro filenames with spaces). 163890792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 163990792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 164090792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 164190792Sgshapiro {if_addr_out} address of interface of outgoing connection. 164290792Sgshapiro {if_family_out} family of interface of outgoing connection. 164390792Sgshapiro The latter two are only set if the interface does not belong 164490792Sgshapiro to the loopback net. 164590792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 164690792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 164790792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 164890792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 164990792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 165090792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 165190792Sgshapiro all connections for a single delivery attempt to succeed. 165290792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 165390792Sgshapiro a threshold number of recipients has been rejected (option 165490792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 165590792Sgshapiro Development Group. 165690792Sgshapiro New option DelayLA to delay connections if the load averages 165790792Sgshapiro exceeds the specified value. The default of 0 does not 165890792Sgshapiro change the previous behavior. A value greater than 0 165990792Sgshapiro will cause sendmail to sleep for one second on most 166090792Sgshapiro SMTP commands and before accepting connections if that 166190792Sgshapiro load average is exceeded. 166290792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 166390792Sgshapiro recipients that are sent during a connection to a mailer. 166490792Sgshapiro This also introduces a new mailer field 'r' which defines 166590792Sgshapiro the maximum number of recipients (defaults to 100). 166690792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 166790792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 166890792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 166990792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 167090792Sgshapiro instead. 167190792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 167290792Sgshapiro builtin mailer pathnames. Use TCP instead. 167390792Sgshapiro PH map code updated to use the new libphclient API instead of the 167490792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 167590792Sgshapiro University of Illinois at Urbana-Champaign. 167690792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 167790792Sgshapiro for direct (command line) submissions. 167890792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 167990792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 168090792Sgshapiro Hagino of the KAME Project. 168190792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 168290792Sgshapiro whose content is rewritten similar to Reply-To:. 168390792Sgshapiro Proposed by Andrzej Filip. 168490792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 168590792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 168690792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 168790792Sgshapiro AUTH/STARTTLS related logfile entries. 168890792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 168990792Sgshapiro before logging. 169090792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 169190792Sgshapiro (at LogLevel 9/10 or higher). 169290792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 169390792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 169490792Sgshapiro in which most commands are rejected due to check_relay or 169590792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 169690792Sgshapiro Change logging format for cloned envelopes to be similar to that for 169790792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 169890792Sgshapiro of the Universitat Regensburg. 169990792Sgshapiro Added libsm, a C library of general purpose abstractions including 170090792Sgshapiro assertions, tracing and debugging with named debug categories, 170190792Sgshapiro exception handling, malloc debugging, resource pools, 170290792Sgshapiro portability abstractions, and an extensible buffered I/O 170390792Sgshapiro package. It will at some point replace libsmutil. 170490792Sgshapiro See libsm/index.html for details. 170590792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 170690792Sgshapiro care of by fork() and exit(). 170790792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 170890792Sgshapiro more consistent portablity amongst different platforms 170990792Sgshapiro new and old (from new libsm). 171090792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 171190792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 171290792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 171390792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 171490792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 171590792Sgshapiro synchronizations calls. 171690792Sgshapiro Add per-recipient status information to mailq -v output. 171790792Sgshapiro T_ANY queries are no longer used by sendmail. 171890792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 171990792Sgshapiro too (see include/sm/cdefs.h for more info). 172090792Sgshapiro sendmail -d now has general support for named debug categories. 172190792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 172290792Sgshapiro for details. 172390792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 172490792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 172590792Sgshapiro generated by this condition were illegal (not RFC conform). 172690792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 172790792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 172890792Sgshapiro mailer and the recipient has hence been rejected during the 172990792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 173090792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 173190792Sgshapiro that do not have postmaster defined. If an email was sent 173290792Sgshapiro from an address to which a DSN cannot be returned and 173390792Sgshapiro in which at least one recipient address is non-deliverable, 173490792Sgshapiro then that email had been delivered in each queue run. 173590792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 173690792Sgshapiro degli Studi dell'Insubria. 173790792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 173890792Sgshapiro i.e., the corresponding code is always compiled in now. 173990792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 174090792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 174190792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 174290792Sgshapiro attempting to canonify a hostname, some broken nameservers 174390792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 174490792Sgshapiro lookups. If you want to excuse this behavior, use this new 174590792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 174690792Sgshapiro Mark Roth of the University of Illinois at 174790792Sgshapiro Urbana-Champaign. 174890792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 174990792Sgshapiro noted by Joy Latten of IBM. 175090792Sgshapiro ConnectionRateThrottle limits the number of connections per second 175190792Sgshapiro to each daemon individually, not the overall number of 175290792Sgshapiro connections. 175390792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 175490792Sgshapiro sendmail to use a default alias schema as outlined in the 175590792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 175690792Sgshapiro cf/README. 175790792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 175890792Sgshapiro the first character after the class name is not a '/' or a 175990792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 176090792Sgshapiro rest of the line will be parsed as a map lookup. This 176190792Sgshapiro allows classes to be filled via a map lookup. See op.me 176290792Sgshapiro for more syntax information. Specifically, this can be 176390792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 176490792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 176590792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 176690792Sgshapiro example). 176790792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 176890792Sgshapiro the default schema used in the above two items. 176990792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 177090792Sgshapiro warning if a program being run from a mailer or file class 177190792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 177290792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 177390792Sgshapiro if a program being run from a mailer or file class 177490792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 177590792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 177690792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 177790792Sgshapiro (without quotes) will disable this and return to the 177890792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 177990792Sgshapiro Suggested by Bryan Stansell of GNAC. 178090792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 178190792Sgshapiro HELO/EHLO commands. 178290792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 178390792Sgshapiro possible protocol family which may be used for outgoing 178490792Sgshapiro connections. Restrictions placed on one family only affect 178590792Sgshapiro outgoing connections on that particular family. Because of 178690792Sgshapiro this change, the ${client_flags} macro is not set until the 178790792Sgshapiro connection is established. Based on patch from Motonori 178890792Sgshapiro Nakamura of Kyoto University. 178990792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 179090792Sgshapiro when the -bv option is given by users who are neither root 179190792Sgshapiro nor the TrustedUser so users can not read private aliases, 179290792Sgshapiro forwards, or :include: files. It also will override the -v 179390792Sgshapiro (verbose) command line option. 179490792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 179590792Sgshapiro address can't be used for the outgoing connection, fall 179690792Sgshapiro back to the settings in ClientPortOptions (if set). 179790792Sgshapiro Problem noted by John Beck of Sun Microsystems. 179890792Sgshapiro New named config file rule check_data for DATA command (input: 179990792Sgshapiro number of recipients). Based on patch from Mark Roth of 180090792Sgshapiro the University of Illinois at Urbana-Champaign. 180190792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 180290792Sgshapiro can be specified using the '#' option character. For 180390792Sgshapiro example, 'ETRN #queuegroup'. 180490792Sgshapiro If an LDAP server times out or becomes unavailable, close the 180590792Sgshapiro current connection and reopen to get to one of the fallback 180690792Sgshapiro servers. Patch from Paul Hilchey of the University of 180790792Sgshapiro British Columbia. 180890792Sgshapiro Make default error number on $#error messages 550 instead of 501 180990792Sgshapiro because 501 is not allowed on all commands. 181090792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 181190792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 181290792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 181390792Sgshapiro if required. 181490792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 181590792Sgshapiro class instead. 181690792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 181790792Sgshapiro "IPv6:" tag to identify the address properly. For example, 181890792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 181990792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 182090792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 182190792Sgshapiro MTA is running. For example, during a queue run. 182290792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 182390792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 182490792Sgshapiro Nelson of IBM. 182590792Sgshapiro The maximum number of commands before the MTA slows down when too 182690792Sgshapiro many "light weight" commands have been received are now 182790792Sgshapiro configurable during compile time. The current values and 182890792Sgshapiro their defaults are: 182990792Sgshapiro MAXBADCOMMANDS 25 unknown commands 183090792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 183190792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 183290792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 183390792Sgshapiro MAXETRNCOMMANDS 8 ETRN 183490792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 183590792Sgshapiro Costales of SL3D, Inc. 183690792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 183790792Sgshapiro ${MyMacro} is defined but also that it is not empty. 183890792Sgshapiro Properly quote usernames with special characters if they are used 183990792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 184090792Sgshapiro Meteorological Institute. 184190792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 184290792Sgshapiro messages for messages for mailing list expanded addresses 184390792Sgshapiro which are not delivered on the initial attempt. 184490792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 184590792Sgshapiro the final dot has been sent to avoid affecting future 184690792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 184790792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 184890792Sgshapiro file systems that require to call fsync() for a directory 184990792Sgshapiro if the meta-data in it has been changed.

Based on 204690792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 204790792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 204890792Sgshapiro doesn't truncate the statistics file. 204990792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 205090792Sgshapiro instead of white space. 205190792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 205290792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 205390792Sgshapiro Meteorological Institute. 205490792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 205590792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 205690792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 205790792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 205890792Sgshapiro instead of syslog. 205990792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 206090792Sgshapiro in the password file. The -f and -m options must be used 206190792Sgshapiro to specify the database and message file since there is no 206290792Sgshapiro home directory for the default settings for these options. 206390792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 206490792Sgshapiro local mail recipients; it reads the MailboxDatabase option 206590792Sgshapiro from the sendmail.cf file. New option -C cffile which 206690792Sgshapiro specifies the path of the sendmail.cf file. 206790792Sgshapiro New Directories: 206890792Sgshapiro libmilter/docs 206990792Sgshapiro New Files: 207090792Sgshapiro cf/cf/README 207190792Sgshapiro cf/cf/submit.cf 207290792Sgshapiro cf/cf/submit.mc 207390792Sgshapiro cf/feature/authinfo.m4 207490792Sgshapiro cf/feature/compat_check.m4 207590792Sgshapiro cf/feature/enhdnsbl.m4 207690792Sgshapiro cf/feature/msp.m4 207790792Sgshapiro cf/feature/local_no_masquerade.m4 207890792Sgshapiro cf/feature/lookupdotdomain.m4 207990792Sgshapiro cf/feature/preserve_luser_host.m4 208090792Sgshapiro cf/feature/preserve_local_plus_detail.m4 208190792Sgshapiro cf/feature/queuegroup.m4 208290792Sgshapiro cf/sendmail.schema 208390792Sgshapiro contrib/dnsblaccess.m4 208490792Sgshapiro devtools/M4/UNIX/sm-test.m4 208590792Sgshapiro devtools/OS/OpenUNIX.5.i386 208690792Sgshapiro editmap/* 208790792Sgshapiro include/sm/* 208890792Sgshapiro libsm/* 208990792Sgshapiro libsmutil/cf.c 209090792Sgshapiro libsmutil/err.c 209190792Sgshapiro sendmail/SECURITY 209290792Sgshapiro sendmail/TUNING 209390792Sgshapiro sendmail/bf.c 209490792Sgshapiro sendmail/bf.h 209590792Sgshapiro sendmail/sasl.c 209690792Sgshapiro sendmail/sm_resolve.c 209790792Sgshapiro sendmail/sm_resolve.h 209890792Sgshapiro sendmail/tls.c 209990792Sgshapiro Deleted Files: 210090792Sgshapiro cf/feature/rbl.m4 210190792Sgshapiro cf/ostype/aix2.m4 210290792Sgshapiro devtools/OS/AIX.2 210390792Sgshapiro include/sendmail/cdefs.h 210490792Sgshapiro include/sendmail/errstring.h 210590792Sgshapiro include/sendmail/useful.h 210690792Sgshapiro libsmutil/errstring.c 210790792Sgshapiro sendmail/bf_portable.c 210890792Sgshapiro sendmail/bf_portable.h 210990792Sgshapiro sendmail/bf_torek.c 211090792Sgshapiro sendmail/bf_torek.h 211190792Sgshapiro sendmail/clock.c 211290792Sgshapiro Renamed Files: 211390792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 211490792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 211590792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 211690792Sgshapiro 211790792Sgshapiro8.11.7/8.11.7 2003/03/29 211890792Sgshapiro SECURITY: Fix a remote buffer overflow in header parsing by 211990792Sgshapiro dropping sender and recipient header comments if the 212090792Sgshapiro comments are too long.

Problem noted by Motonori Nakamura 247673188Sgshapiro of Kyoto University. 247773188Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 247873188Sgshapiro causes some changes in behavior and may break rmail for 247973188Sgshapiro installations where sendmail is actually a wrapper to 248073188Sgshapiro another MTA. The change will re-appear in a future 248173188Sgshapiro version. 248273188Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 248373188Sgshapiro and SunOS 5.8.

This more closely 258271345Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 258371345Sgshapiro Ericsson. 258471345Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 258571345Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 258671345Sgshapiro mailer as described in cf/README. 258771345Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 258871345Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 258971345Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 259071345Sgshapiro makemap to 'unmake' the map. 259171345Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 259271345Sgshapiro sendmail. 259371345Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 259471345Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 259571345Sgshapiro Meteorological Institute. 259671345Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 259771345Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 259871345Sgshapiro dot as the only character on the line. 259971345Sgshapiro New Files: 260071345Sgshapiro cf/ostype/solaris8.m4 260171345Sgshapiro 260271345Sgshapiro8.11.0/8.11.0 2000/07/19 260371345Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 260471345Sgshapiro (not the normal case), some operating systems will still 260571345Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 260671345Sgshapiro to drop all of its privileges. If sendmail needs to drop 260771345Sgshapiro these privileges and the operating system doesn't set the 260871345Sgshapiro saved-uid as well, exit with an error. Problem noted by 260971345Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 261071345Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 261171345Sgshapiro it populates. It is possible that some broken 261271345Sgshapiro implementations of snprintf() exist that do not do this. 261371345Sgshapiro Systems in this category should compile with 261471345Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 261571345Sgshapiro system and report broken implementations to 261671345Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 261771345Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 261871345Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 261971345Sgshapiro Implementation influenced by the example programs of 262073188Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 262171345Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 262271345Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 262371345Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 262471345Sgshapiro cf/README and doc/op/op.*. 262571345Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 262671345Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 262771345Sgshapiro ${server_name}, and ${server_addr}. These are documented 262871345Sgshapiro in cf/README and doc/op/op.*. 262971345Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 263071345Sgshapiro random data. 263171345Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 263271345Sgshapiro don't properly seed the PRNG for OpenSSL but want to 263371345Sgshapiro try to use STARTTLS despite the security problems. 263471345Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 263571345Sgshapiro support encryption. Based on code contributed by Tim 263671345Sgshapiro Martin of CMU. 263771345Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 263873188Sgshapiro strength factor. 263971345Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 264071345Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 264171345Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 264271345Sgshapiro of CMU. 264371345Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 264471345Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 264571345Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 264671345Sgshapiro Fix the default family selection for DaemonPortOptions. As 264771345Sgshapiro documented, unless a family is specified in a 264871345Sgshapiro DaemonPortOptions option, "inet" is the default. It is 264971345Sgshapiro also the default if no DaemonPortOptions value is set. 265071345Sgshapiro Therefore, IPv6 users should configure additional sockets 265171345Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 265271345Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 265371345Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 265471345Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 265571345Sgshapiro the interface information for an outgoing connection. 265666494Sgshapiro Not doing so was creating a mismatch between the socket 265766494Sgshapiro family and address used in subsequent connections if the 265866494Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 265966494Sgshapiro by John Beck of Sun Microsystems. 266066494Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 266166494Sgshapiro family based on the IP address. ${if_family} is no longer 266266494Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 266366494Sgshapiro of Sun Microsystems. 266466494Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 266566494Sgshapiro macros for both the incoming interface address/family and 266666494Sgshapiro the outgoing interface address/family. In order for M=b 266766494Sgshapiro modifier in DaemonPortOptions to work properly, preserve 266866494Sgshapiro the incoming information in the queue file for later 266966494Sgshapiro delivery attempts. 267066494Sgshapiro Use SMTP error code and enhanced status code from check_relay in 267166494Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 267266494Sgshapiro smoe.org. 267366494Sgshapiro Add more vigilance in checking for putc() errors on output streams 267466494Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 267566494Sgshapiro noted by Graeme Hewson of Oracle. 267666494Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 267766494Sgshapiro Problem noted by Ajay Matia. 267871345Sgshapiro Under certain circumstances, an address could be listed as deferred 267971345Sgshapiro but would be bounced back to the sender as failed to be 268066494Sgshapiro delivered when it really should have been queued. Problem 268166494Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 268266494Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 268366494Sgshapiro the SMTP transaction out of sync. Problem noted by Per 268466494Sgshapiro Hedeland of Ericsson. 268566494Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 268666494Sgshapiro is defined to avoid a core dump due to incompatibilities 268766494Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 268866494Sgshapiro of Northern Illinois University. 268966494Sgshapiro Don't log useless envelope ID on initial connection log. Problem 269066494Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 269166494Sgshapiro Convert the free disk space shown in a control socket status query 269266494Sgshapiro to kilobyte units. 269366494Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 269466494Sgshapiro looking up the hostname, requeue the message for a later 269566494Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 269666494Sgshapiro Polytechnic. 269766494Sgshapiro Under the proper circumstances, failed connections would be recorded 269866494Sgshapiro as "Bad file number" instead of "Connection failed" in the 269966494Sgshapiro queue file and persistent host status. Problem noted by 270066494Sgshapiro Graeme Hewson of Oracle. 270166494Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 270266494Sgshapiro within the hoststatus directory (e.g., lost+found). 270366494Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 270466494Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 270566494Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 270666494Sgshapiro If a message data file can't be opened at delivery time, panic and 270766494Sgshapiro abort the attempt instead of delivering a message that 270866494Sgshapiro states "<<< No Message Collected >>>". 270966494Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 271066494Sgshapiro restrictive.

This option and 298364562Sgshapiro its use is deprecated and will be removed from a future 298464562Sgshapiro version of sendmail. 298564562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 298664562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 298764562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 298864562Sgshapiro (IdS). 298964562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 299064562Sgshapiro a large number of files. See cf/README for more details. 299164562Sgshapiro The directory structure of the distribution has changed slightly 299264562Sgshapiro for easier code sharing among the programs. 299364562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 299464562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 299564562Sgshapiro which hold the client's authentication credentials, 299664562Sgshapiro the mechanism used for authentication, and the 299764562Sgshapiro authorization identity (i.e., the AUTH= parameter if 299864562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 299964562Sgshapiro On systems which use the Torek stdio library (all of the BSD 300064562Sgshapiro distributions), use memory-buffered files to reduce 300164562Sgshapiro file system overhead by not creating temporary files on 300264562Sgshapiro disk.

Use: 301164562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 301264562Sgshapiro to run a Message Submission Agent (MSA); this is turned 301364562Sgshapiro on by default in m4-generated .cf files; it can be turned 301464562Sgshapiro off with FEATURE(`no_default_msa'). 301564562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 301664562Sgshapiro begin using RFC 2476 Message Submission for initial user 301764562Sgshapiro message submission. XUSR may disappear from a future release. 301864562Sgshapiro The new '-G' (relay (gateway) submission) command line option 301964562Sgshapiro indicates that the message being submitted from the command 302064562Sgshapiro line is for relaying, not initial submission. This means 302164562Sgshapiro the message will be rejected if the addresses are not fully 302264562Sgshapiro qualified and no canonicalization will be done. Future 302364562Sgshapiro releases may even reject improperly formed messages. 302464562Sgshapiro The '-U' (initial user submission) command line option is 302564562Sgshapiro deprecated and may be removed from a future release. 302664562Sgshapiro Mail user agents should begin using '-G' to indicate that 302764562Sgshapiro this is a relay submission (the inverse of -U). 302864562Sgshapiro The next release of sendmail will assume that any message submitted 302964562Sgshapiro from the command line is an initial user submission and act 303064562Sgshapiro accordingly. 303164562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 303264562Sgshapiro program or deliver to file as the owner of that file, the 303364562Sgshapiro address is marked as unsafe. This means if RunAsUser is 303464562Sgshapiro set, users won't be able to use programs or delivery to 303564562Sgshapiro files in their .forward files. Administrators can override 303664562Sgshapiro this by setting the DontBlameSendmail option to the new 303764562Sgshapiro setting NonRootSafeAddr. 303864562Sgshapiro Allow group or world writable directories if the sticky bit is set 303964562Sgshapiro on the directory and DontBlameSendmail is set to 304064562Sgshapiro TrustStickyBit.

To use multiple queues, supply 307364562Sgshapiro a QueueDirectory option value ending with an asterisk. For 307464562Sgshapiro example, /var/spool/mqueue/q* will use all of the 307564562Sgshapiro directories or symbolic links to directories beginning with 307664562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 307764562Sgshapiro mind, the queue directory structure should not be changed 307864562Sgshapiro while sendmail is running. Queue runs create a separate 307964562Sgshapiro process for running each queue unless the verbose flag is 308064562Sgshapiro given on a non-daemon queue run. New items are randomly 308164562Sgshapiro assigned to a queue.

Keep in mind, the queue 308664562Sgshapiro directory structure should not be changed while sendmail is 308764562Sgshapiro running. Proposed by Mathias Koerber of Singapore 308864562Sgshapiro Telecommunications Ltd. 308964562Sgshapiro New queue file naming system which uses a filename guaranteed to be 309064562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 309164562Sgshapiro without fancy file system locking. Queued items can be 309264562Sgshapiro moved between queues easily. Contributed by Exactis.com, 309364562Sgshapiro Inc. 309464562Sgshapiro Messages which are undeliverable due to temporary address failures 309564562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 309664562Sgshapiro set. Contributed by Exactis.com, Inc. 309764562Sgshapiro New command line option '-L tag' which sets the identifier used for 309864562Sgshapiro syslog. Contributed by Exactis.com, Inc. 309964562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 310064562Sgshapiro avoids opening and reading each queue file when preparing 310164562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 310264562Sgshapiro Shared memory counters and microtimers functionality has been 310364562Sgshapiro donated by Exactis.com, Inc. 310464562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 310564562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 310664562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 310764562Sgshapiro being added. Suggested by Michael K. Sanders. 310864562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 310964562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 311064562Sgshapiro and John Beck of Sun Microsystems. 311164562Sgshapiro In low-disk space situations, where sendmail would previously refuse 311264562Sgshapiro connections, still accept them, but only allow ETRN commands. 311364562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 311464562Sgshapiro Ltd. 311564562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 311664562Sgshapiro on systems which support them. This can be used with LMTP 311764562Sgshapiro local delivery agents which listen on a named socket. An 311864562Sgshapiro example mailer might be: 311964562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 312064562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 312164562Sgshapiro A=FILE /var/run/lmtpd 312280785Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 312380785Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 312480785Sgshapiro instead. 312580785Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 312680785Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 312780785Sgshapiro connections), IPC (which will be deprecated in a future 312880785Sgshapiro version), and FILE (for UNIX domain socket delivery). 312980785Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 313080785Sgshapiro flags. 313180785Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 313280785Sgshapiro body of the original message on delivery status 313380785Sgshapiro notifications. 313464562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 313564562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 313664562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 313764562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 313864562Sgshapiro Steve Schweinhart of America Online. 313964562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 314064562Sgshapiro not be set after rulesets are defined. Suggested by 314164562Sgshapiro Mitchell Blank Jr of Exec-PC. 314264562Sgshapiro Do not report temporary failure on delivery to files. In 314364562Sgshapiro interactive delivery mode, this would result in two SMTP 314464562Sgshapiro responses after the DATA command. Problem noted by 314564562Sgshapiro Nik Conwell of Boston University. 314664562Sgshapiro Check file close when mailing to files. Problem noted by Nik 314764562Sgshapiro Conwell of Boston University. 314864562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 314964562Sgshapiro Curtis W. Hillegas of Princeton University. 315064562Sgshapiro Always bind to the LDAP server regardless of whether you are using 315164562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 315264562Sgshapiro @Home Network. 315364562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 315464562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 315564562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 315664562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 315764562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 315864562Sgshapiro similar to check_rcpt etc. 315964562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 316064562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 316164562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 316264562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 316364562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 316464562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 316564562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 316664562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 316764562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 316864562Sgshapiro the corresponding DSN parameter values. Proposed by 316964562Sgshapiro Mathias Herberts. 317064562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 317164562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 317264562Sgshapiro before the message has been collected, thereafter it holds 317364562Sgshapiro the message size as computed by sendmail (and can be used 317464562Sgshapiro in check_compat). 317564562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 317664562Sgshapiro sendmail is using instead of the value of the DeliveryMode 317764562Sgshapiro option. 317864562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 317964562Sgshapiro Drop explicit From: if same as what would be generated only if it is 318064562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 318164562Sgshapiro Write pid to file also if sendmail only processes the queue. 318264562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 318364562Sgshapiro Log "low on disk space" only when necessary. 318464562Sgshapiro New macro ${load_avg} can be used to check the current load average. 318564562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 318664562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 318764562Sgshapiro is set. 318864562Sgshapiro Flag -S for maps to specify the character which is substituted 318964562Sgshapiro for spaces (instead of the default given by O BlankSub). 319064562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 319164562Sgshapiro This flag is set by default for the host map. Based on a 319264562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 319364562Sgshapiro Open maps only on demand, not at startup. 319464562Sgshapiro Log warning about unsupported IP address families. 319564562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 319664562Sgshapiro of the sum of all headers. This can be used to prevent 319764562Sgshapiro a denial-of-service attack. 319864562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 319964562Sgshapiro headers and parameters within those headers. This option 320064562Sgshapiro is intended to protect mail user agents from buffer 320164562Sgshapiro overflow attacks. 320264562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 320364562Sgshapiro alias recursion. 320464562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 320564562Sgshapiro Map type syslog to log the key via syslogd. 320664562Sgshapiro Entries in the alias file can be continued by putting a backslash 320764562Sgshapiro directly before the newline. 320864562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 320964562Sgshapiro dead.letter file, formerly hardcoded to 321064562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 321164562Sgshapiro default), sendmail will not attempt to save to a 321264562Sgshapiro system-wide dead.letter file if it can not bounce the mail 321364562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 321464562Sgshapiro file as it has in the past when the dead.letter file 321564562Sgshapiro could not be opened. 321664562Sgshapiro New option PidFile to define the location of the pid file. The 321764562Sgshapiro value of this option is macro expanded. 321864562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 321964562Sgshapiro process title shown in 'ps' listings. 322064562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 322164562Sgshapiro (along with the already existing macros): 322264562Sgshapiro ${daemon_info} Daemon information, e.g. 322364562Sgshapiro SMTP+queueing@00:30:00 322464562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 322564562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 322664562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 322764562Sgshapiro ${daemon_port} Daemon port, e.g., 25 322864562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 322964562Sgshapiro New macros especially for virtual hosting: 323064562Sgshapiro ${if_name} hostname of interface of incoming connection. 323164562Sgshapiro ${if_addr} address of interface of incoming connection. 323264562Sgshapiro The latter is only set if the interface does not belong to the 323364562Sgshapiro loopback net. 323464562Sgshapiro If a message being accepted via a method other than SMTP and 323564562Sgshapiro would be rejected by a header check, do not send the message. 323664562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 323764562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 323864562Sgshapiro Provide header value as quoted string in the macro 323964562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 324064562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 324164562Sgshapiro The length of the header value is stored in ${hdrlen}. 324264562Sgshapiro H*: allows to specify a default ruleset for header checks. This 324364562Sgshapiro ruleset will only be called if the individual header does 324464562Sgshapiro not have its own ruleset assigned. Suggested by Jan 324564562Sgshapiro Krueger of Unix-AG of University of Hannover. 324664562Sgshapiro The name of the header field stored in ${hdr_name}. 324764562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 324864562Sgshapiro removed if the config file version is greater than or equal 324964562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 325064562Sgshapiro input "token (1)" but does not match "token". 325164562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 325264562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 325364562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 325464562Sgshapiro Ericsson. 325564562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 325664562Sgshapiro messages with 8-bit text in headers. Problem noted by 325764562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 325864562Sgshapiro of Ericsson. 325964562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 326064562Sgshapiro modified database map file. Problem noted by Chris Adams 326164562Sgshapiro of Renaissance Internet Services. 326264562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 326364562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 326464562Sgshapiro queue up the message instead of bouncing it. 326564562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 326664562Sgshapiro standard does not provide any indication of what to do when 326764562Sgshapiro something other than 250 is received. Based on a patch 326864562Sgshapiro from Steve Schweinhart of America Online. 326964562Sgshapiro New option TrustedUser allows to specify a user who can own 327064562Sgshapiro important files instead of root. This requires HASFCHOWN. 327164562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 327264562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 327364562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 327464562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 327564562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 327664562Sgshapiro $? tests also whether the macro is non-null. 327764562Sgshapiro Print an error message if a mailer definition contains an invalid 327864562Sgshapiro equate name. 327964562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 328064562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 328164562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 328264562Sgshapiro mailer to return after sending all data to it. 328364562Sgshapiro Only free memory from the process list when adding a new process 328464562Sgshapiro into a previously filled slot. Previously, the memory was 328564562Sgshapiro freed at removal time. Since removal can happen in a 328664562Sgshapiro signal handler, this may leave the memory map in an 328764562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 328864562Sgshapiro David Cooley of Colby College. 328964562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 329064562Sgshapiro local users in the passwd file. The UserDB code has 329164562Sgshapiro already decided the message will be passed to another host 329264562Sgshapiro for processing. Fix from Tony Landells of Burdett 329364562Sgshapiro Buckeridge Young Limited. 329464562Sgshapiro Support LDAP authorization via either a file containing the 329564562Sgshapiro password or Kerberos V4 using the new map options 329664562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 329764562Sgshapiro distinguished_name is who to login as. The method can be 329864562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 329964562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 330064562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 330164562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 330264562Sgshapiro of Stanford University. 330364562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 330464562Sgshapiro deprecated and will be removed in a future version. 330564562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 330664562Sgshapiro and the map has the column delimiter set, it turns that 330764562Sgshapiro response into a delimiter separated string. The LDAP map 330864562Sgshapiro will traverse multiple entries as well. LDAP alias maps 330964562Sgshapiro automatically set the column delimiter to the comma. 331064562Sgshapiro Based on patch from Booker Bense of Stanford University and 331164562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 331264562Sgshapiro Support return of multiple values for a single LDAP lookup. The 331364562Sgshapiro values to be returned should be in a comma separated string. 331464562Sgshapiro For example, `-v "email,emailother"'. Patch from 331564562Sgshapiro Curtis W. Hillegas of Princeton University. 331664562Sgshapiro Allow the use of LDAP for alias maps. 331764562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 331864562Sgshapiro attributes found in the match will be returned. 331964562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 332064562Sgshapiro breaking up a single entry into multiple entries. This is 332164562Sgshapiro needed for LDAP alias file specifications to allow for 332264562Sgshapiro comma separated key and value strings. 332364562Sgshapiro Keep connections to LDAP server open instead of opening and closing 332464562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 332564562Sgshapiro connections such that multiple maps which use the same 332664562Sgshapiro host, port, bind DN, and authentication will only result in 332764562Sgshapiro a single connection to that host. 332864562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 332964562Sgshapiro Be more careful about checking for errors and freeing memory on 333064562Sgshapiro LDAP lookups. 333164562Sgshapiro Use asynchronous LDAP searches to save memory and network 333264562Sgshapiro resources. 333364562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 333464562Sgshapiro Increase portability to the Netscape LDAP libraries. 333564562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 333664562Sgshapiro replaced with the literal contents of the map lookup key -- 333764562Sgshapiro note that this means a lookup can be done using the LDAP 333864562Sgshapiro special characters. The new '%0' token can be used instead 333964562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 334064562Sgshapiro For example, if the LDAP map specification contains '-k 334164562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 334264562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 334364562Sgshapiro user attribute. Instead, if the LDAP map specification 334464562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 334564562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 334664562Sgshapiro with the name "*". 334764562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 334864562Sgshapiro more than one is returned, it is equivalent to no records 334964562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 335064562Sgshapiro alias dereference option; "-Z size" limits the number of 335164562Sgshapiro matches to return. 335264562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 335364562Sgshapiro LDAP maps. The value should only contain LDAP specific 335464562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 335564562Sgshapiro settings will be used for all LDAP maps unless they are 335664562Sgshapiro specified in the individual map specification ('K' 335764562Sgshapiro command). This option should be set before any LDAP maps 335864562Sgshapiro are defined. 335964562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 336064562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 336164562Sgshapiro Tech. 336264562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 336364562Sgshapiro particular, class entries get much smaller, which can be 336464562Sgshapiro important if you have large classes. 336564562Sgshapiro On network-related temporary failures, record the hostname which 336664562Sgshapiro gave error in the queued status message. Requested by 336764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 336864562Sgshapiro Add new F=% mailer flag to allow for a store and forward 336964562Sgshapiro configuration. Mailers which have this flag will not attempt 337064562Sgshapiro delivery on initial receipt of a message or on queue runs 337164562Sgshapiro unless the queued message is selected using one of the 337264562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 337364562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 337464562Sgshapiro New option ControlSocketName which, when set, creates a daemon 337564562Sgshapiro control socket. This socket allows an external program to 337664562Sgshapiro control and query status from the running sendmail daemon 337764562Sgshapiro via a named socket, similar to the ctlinnd interface to the 337864562Sgshapiro INN news server. Access to this interface is controlled by 337964562Sgshapiro the UNIX file permissions on the named socket on most UNIX 338064562Sgshapiro systems (see sendmail/README for more information). An 338164562Sgshapiro example control program is provided as contrib/smcontrol.pl. 338264562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 338364562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 338464562Sgshapiro number of processors online on the system (if that can be 338564562Sgshapiro determined). For single processor machines, this change 338664562Sgshapiro has no effect. 338764562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 338864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 338964562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 339064562Sgshapiro Motonori Nakamura of Kyoto University. 339164562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 339264562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 339364562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 339464562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 339564562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 339664562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 339764562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 339864562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 339964562Sgshapiro connection-based denial of service attacks. 340064562Sgshapiro Log basic information about authenticated connections at LogLevel 340164562Sgshapiro 10 or higher. 340264562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 340364562Sgshapiro information (from= syslog line). 340464562Sgshapiro Log the DSN code for each recipient if one is available as a new 340564562Sgshapiro equate (dsn=). 340664562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 340764562Sgshapiro New "ph" map for performing ph queries in rulesets, see 340864562Sgshapiro sendmail/README for details. Contributed by Mark Roth 340964562Sgshapiro of the University of Illinois at Urbana-Champaign. 341064562Sgshapiro Detect temporary lookup failures in the host map if looking up a 341164562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 341264562Sgshapiro Finnish Meteorological Institute. 341364562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 341464562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 341564562Sgshapiro When a forward file points to an alias which runs a program, run 341664562Sgshapiro the program as the default user and the default group, not 341764562Sgshapiro the forward file user. This change also assures the 341864562Sgshapiro :include: directives in aliases are also processed using 341964562Sgshapiro the default user and group. Problem noted by Sergiu 342064562Sgshapiro Popovici of DNT Romania. 342164562Sgshapiro Prevent attempts to save a dead.letter file for a user with 342264562Sgshapiro no home directory (/no/such/directory). Problem noted by 342364562Sgshapiro Michael Brown of Finnigan FT/MS. 342464562Sgshapiro Include message delay and number of tries when logging that a 342564562Sgshapiro message has been completely delivered (LogLevel of 10 or 342664562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 342764562Sgshapiro Log the sender of a message even if none of the recipients were 342864562Sgshapiro accepted. If some of the recipients were rejected, it is 342964562Sgshapiro helpful to know the sender of the message. 343064562Sgshapiro Check the root directory (/) when checking a path for safety. 343164562Sgshapiro Problem noted by John Beck of Sun Microsystems. 343264562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 343364562Sgshapiro interactive and delivering to an alias which resolves to 343464562Sgshapiro multiple files. 343564562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 343664562Sgshapiro greater (see below); the help function doesn't print the 343764562Sgshapiro version of sendmail any longer, instead it is placed in 343864562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 343964562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 344064562Sgshapiro skipped and a version line (#vers) is introduced. The 344164562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 344264562Sgshapiro version is found, a warning is logged. The '#vers' 344364562Sgshapiro directive should be placed at the top of the help file. 344464562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 344564562Sgshapiro disk succeeded. Suggested by Nick Christenson. 344664562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 344764562Sgshapiro length before the attempt. 344864562Sgshapiro If a forward points to a filename for delivery, change to the 344964562Sgshapiro user's uid before checking permissions on the file. This 345064562Sgshapiro allows delivery to files on NFS mounted directories where 345164562Sgshapiro root is remapped to nobody. Problem noted by Harald 345264562Sgshapiro Daeubler of Universitaet Ulm. 345364562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 345464562Sgshapiro host status files, not all files. 345564562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 345664562Sgshapiro in the queue file for the message and set when delivery 345764562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 345864562Sgshapiro Wonderworks Inc. 345964562Sgshapiro Add support for storing information between rulesets using the new 346064562Sgshapiro macro map class. This can be used to store information 346164562Sgshapiro between queue runs as well using $={persistentMacros}. 346264562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 346364562Sgshapiro of Hannover. 346464562Sgshapiro New map class arith to allow for computations in rules. The 346564562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 346664562Sgshapiro as key. The two operands are specified as arguments; the 346764562Sgshapiro lookup returns the result of the computation. For example, 346864562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 346964562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 347064562Sgshapiro Add new syntax for header declarations which decide whether to 347164562Sgshapiro include the header based on a macro rather than a mailer 347264562Sgshapiro flag: 347364562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 347464562Sgshapiro This should be used along with $={persistentMacros}. 347564562Sgshapiro It can be used for adding headers to a message based on 347664562Sgshapiro the results of check_* and header check rulesets. 347764562Sgshapiro Allow new named config file rule check_eoh which is called after 347864562Sgshapiro all of the headers have been collected. The input to the 347964562Sgshapiro ruleset the number of headers and the size of all of the 348064562Sgshapiro headers in bytes separated by $|. This ruleset along with 348164562Sgshapiro the macro storage map can be used to correlate information 348264562Sgshapiro gathered between headers and to check for missing headers. 348364562Sgshapiro See cf/README or doc/op/op.ps for an example. 348464562Sgshapiro Change the default for the MeToo option to True to correspond 348564562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 348664562Sgshapiro option is deprecated and will be removed from a future 348764562Sgshapiro version. 348864562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 348964562Sgshapiro Change the sendmail binary default for SuperSafe to True. 349064562Sgshapiro Display ruleset names in debug and address test mode output 349164562Sgshapiro if referencing a named ruleset. 349264562Sgshapiro New mailer equate m= which will limit the number of messages 349364562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 349464562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 349564562Sgshapiro using it to sort. Now all the same domains are really run 349664562Sgshapiro through the queue together. If they have the same MX host, 349764562Sgshapiro then they will have a much better opportunity to use the 349864562Sgshapiro connection cache if available. This should be a reasonable 349964562Sgshapiro performance improvement. Patch from Randall Winchester of 350064562Sgshapiro the University of Maryland. 350164562Sgshapiro If a message is rejected by a header check ruleset, log who would 350264562Sgshapiro have received the message if it had not been rejected. 350364562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 350464562Sgshapiro queue immediately. No delivery attempt is made. 350564562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 350664562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 350764562Sgshapiro COMMANDS). 350864562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 350964562Sgshapiro but for outgoing connections. 351064562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 351164562Sgshapiro error messages and logging) and Modifiers, i.e. 351264562Sgshapiro a require authentication 351364562Sgshapiro b bind to interface through which mail has 351464562Sgshapiro been received 351564562Sgshapiro c perform hostname canonification 351664562Sgshapiro f require fully qualified hostname 351764562Sgshapiro h use name of interface for outgoing HELO 351864562Sgshapiro command 351964562Sgshapiro C don't perform hostname canonification 352064562Sgshapiro E disallow ETRN (see RFC 2476) 352164562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 352264562Sgshapiro h use name of interface for HELO command 352364562Sgshapiro The version number for queue files (qf) has been incremented to 4. 352464562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 352564562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 352664562Sgshapiro Institutes of Health. 352764562Sgshapiro If a mailer dies, print the status in decimal instead of octal 352864562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 352964562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 353064562Sgshapiro Move message priority from sender to recipient logging. Suggested by 353164562Sgshapiro Ulrich Windl of the Universitat Regensburg. 353264562Sgshapiro Add support for Berkeley DB 3.X. 353371345Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 353464562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 353564562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 353664562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 353764562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 353864562Sgshapiro sub-options is set on the command line. Problem noted by 353964562Sgshapiro Graeme Hewson of Oracle. 354064562Sgshapiro Randomize equal preference MX records each time delivery is 354164562Sgshapiro attempted via a new connection to a host instead of once per 354264562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 354364562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 354464562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 354564562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 354664562Sgshapiro to hosts which have dynamically assigned names. 354764562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 354864562Sgshapiro the bounce for the same reason. If the body is not 8-bit 354964562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 355064562Sgshapiro not be included in the bounce. Problem noted by Valdis 355164562Sgshapiro Kletnieks of Virginia Tech. 355264562Sgshapiro The timeout for sending a message via SMTP has been changed from 355364562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 355464562Sgshapiro simply checks for progress on sending data every 5 minutes. 355564562Sgshapiro This will detect the inability to send information quicker 355664562Sgshapiro and reduce the number of processes simply waiting to 355764562Sgshapiro timeout. 355864562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 355964562Sgshapiro interface address structure when loading the system network 356064562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 356164562Sgshapiro Nanoteq. 356264562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 356364562Sgshapiro indicates the number of interfaces to read when probing 356464562Sgshapiro for hostnames and IP addresses for class w ($=w). The 356564562Sgshapiro default value is 512. Based on idea from Reinier 356664562Sgshapiro Bezuidenhout of Nanoteq. 356764562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 356864562Sgshapiro on load average. 356964562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 3570120256Sgshapiro Northern Illinois University. 3571120256Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 3572120256Sgshapiro envelope splitting has occurred. 357364562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 357464562Sgshapiro Luke Mewburn from RMIT University. 357564562Sgshapiro Add a "/quit" command to address test mode. 357664562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 357764562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 357864562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 357964562Sgshapiro Institute. 358064562Sgshapiro The contents of a class can now be copied to another class using 358164562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 358264562Sgshapiro the items in class $={Source} into the class $={Dest}. 358364562Sgshapiro Include original envelope's error transcript in bounces created for 358464562Sgshapiro split (owner-) envelopes to see the original errors when 358564562Sgshapiro the recipients were added. Based on fix from Motonori 358664562Sgshapiro Nakamura of Kyoto University. 358764562Sgshapiro Show reason for permanent delivery errors directly after the 358864562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 358964562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 359064562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 359164562Sgshapiro If the specification for the queue run interval (-q###) has a 359264562Sgshapiro syntax error, consider the error fatal and exit. 359364562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 359464562Sgshapiro noted by Motonori Nakamura of Kyoto University. 359564562Sgshapiro On operating systems which have setlogin(2), use it to set the 359664562Sgshapiro login name to the RunAsUserName when starting as a daemon. 359764562Sgshapiro This is for delivery to programs which use getlogin(). 359864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 359964562Sgshapiro Differentiate between "command not implemented" and "command 360064562Sgshapiro unrecognized" in the SMTP dialogue. 360164562Sgshapiro Strip returns from forward and include files. Problem noted by 360264562Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 360364562Sgshapiro Prevent a core dump when using 'sendmail -bv' on an address which 360464562Sgshapiro resolves to the $#error mailer with a temporary failure. 360564562Sgshapiro Based on fix from Neil Rickert of Northern Illinois 360664562Sgshapiro University. 360764562Sgshapiro Prevent multiple deliveries of a message with a "non-local alias" 360864562Sgshapiro pointing to a local user, if canonicalization fails 360964562Sgshapiro the message was requeued *and* delivered to the alias. 361064562Sgshapiro If an invalid ruleset is declared, the ruleset name could be 361164562Sgshapiro ignored and its rules added to S0. Instead, ignore the 361264562Sgshapiro ruleset lines as well. 361364562Sgshapiro Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient 361464562Sgshapiro success DSN fields as well as duplicate entries for a 361564562Sgshapiro single address due to S5 and UserDB processing. Problems 361664562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological 361764562Sgshapiro Institute. 361864562Sgshapiro Turn off timeouts when exiting sendmail due to an interrupt signal 361964562Sgshapiro to prevent the timeout from firing during the exit process. 362064562Sgshapiro Problem noted by Michael Shapiro of Sun Microsystems. 362164562Sgshapiro Do not append @MyHostName to non-RFC822 addresses output by the EXPN 362264562Sgshapiro command or on Final-Recipient: and X-Actual-Recipient: DSN 362364562Sgshapiro headers. Non-RFC822 addresses include deliveries to 362464562Sgshapiro programs, file, DECnet, etc. 362564562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 362664562Sgshapiro spoof their return address. Based on idea from Neil Rickert 362764562Sgshapiro of Northern Illinois University and patch from Per Hedeland 362864562Sgshapiro of Ericsson. 362964562Sgshapiro Report the proper UID in the bounce message if an :include: file is 363064562Sgshapiro owned by a uid that doesn't map to a username and the 363164562Sgshapiro :include: file contains delivery to a file or program. 363264562Sgshapiro Problem noted by John Beck of Sun Microsystems. 363364562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 363464562Sgshapiro the remote server responds to the first QUIT with a 4xx 363564562Sgshapiro response code and drops the connection. This behavior was 363664562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 363764562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 363864562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 363964562Sgshapiro file is not present, the lookup failure would be marked as 364064562Sgshapiro a permanent failure instead of a temporary failure.

Problem noted by Juergen Georgi of RUS University 365664562Sgshapiro of Stuttgart and Kyle Tucker of Parexel International. 365764562Sgshapiro Prevent +detail information from interfering with local delivery to 365864562Sgshapiro multiple users in the same transaction (F=m). 365964562Sgshapiro Add H_FORCE flag for the X-Authentication-Warning: header, so it 366064562Sgshapiro will be added even if one already exists. Problem noted 366164562Sgshapiro by Michal Zalewski of Marchew Industries. 366264562Sgshapiro Stop processing SMTP commands if the SMTP connection is dropped. 366364562Sgshapiro This prevents a remote system from flooding the connection 366464562Sgshapiro with commands and then disconnecting. Previously, the 366564562Sgshapiro server would process all of the buffered commands.

Suggested by many. 367764562Sgshapiro Persistent host status data is not reloaded disk when current data 367864562Sgshapiro is available in the in-memory cache. Problem noted by Per 367964562Sgshapiro Hedeland of Ericsson. 368064562Sgshapiro mailq displays unprintable characters in addresses as their octal 368164562Sgshapiro representation and a leading backslash. This avoids problems 368264562Sgshapiro with "unprintable" characters. Problem noted by Michal 368364562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 368464562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 368564562Sgshapiro one character past the limit. This would cause subsequent 368664562Sgshapiro hops to break the line again. The '!' is now placed in 368764562Sgshapiro the last column of the limit if the line needs to be broken. 368864562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 368964562Sgshapiro from Per Hedeland of Ericsson. 369064562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 369164562Sgshapiro resolver will fall back to TCP.

Panepucci of 399964562Sgshapiro Yale University. 400064562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 400164562Sgshapiro be used for building. 400264562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 400364562Sgshapiro used for a fresh build. 400464562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 400564562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 400664562Sgshapiro ranlib. 400764562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 400864562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 400964562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 401064562Sgshapiro building of the man pages when defined. Suggested by Bryan 401164562Sgshapiro Costales. 401264562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 401364562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 401464562Sgshapiro installation of the sendmail helpfile and statistics file 401564562Sgshapiro respectively. Suggested by Bryan Costales. 401664562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 401764562Sgshapiro of Siemens Business Services. 401864562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 401964562Sgshapiro stdio library. The new buffered file I/O depends on the 402064562Sgshapiro Torek stdio library. This option can be either portable or 402164562Sgshapiro torek. 402264562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 402364562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 402464562Sgshapiro They should contain the C source files for the object files 402564562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 402664562Sgshapiro will be passed to the 'make depend' stage of compilation. 402764562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 402864562Sgshapiro in the sendmail distribution. Each has the form 402964562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 403064562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 403164562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 403264562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 403364562Sgshapiro building the distribution, but documentation on the changes 403464562Sgshapiro are in devtools/README. 403564562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 403664562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 403764562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 403864562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 403964562Sgshapiro new variable which identifies the root of the source 404064562Sgshapiro directories for all of the programs in the distribution. 404164562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 404264562Sgshapiro time. They can both still be overridden by setting the m4 404364562Sgshapiro macro. 404464562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 404564562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 404664562Sgshapiro build configurations, and places objects in obj.prefix.*/. 404764562Sgshapiro Complains as 'Build -f file' does for existing object 404864562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 404964562Sgshapiro Corporation. 405064562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 405164562Sgshapiro manual pages in the directory tree specified by 405264562Sgshapiro confMANROOTMAN. 405364562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 405464562Sgshapiro preformatted pages from the distribution. The new variable 405564562Sgshapiro confCOPY specifies the copying program. 405664562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 405764562Sgshapiro question. Suggested by Terry Lambert of Whistle 405864562Sgshapiro Communications. 405964562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 406064562Sgshapiro of the installed statistics and help files, respectively. 406164562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 406264562Sgshapiro operating system identity. Problem noted by Erik 406364562Sgshapiro Wachtenheim of Dartmouth College. 406464562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 406564562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 406664562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 406764562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 406864562Sgshapiro how to strip binaries. These are used by the new 406964562Sgshapiro install-strip target. 407064562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 407164562Sgshapiro the others (if it exists). 407264562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 407364562Sgshapiro then the default ones. 407464562Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 407564562Sgshapiro as local delivery agent without LMTP mode, use 407664562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 407764562Sgshapiro to set the S flag. 407864562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 407964562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 408064562Sgshapiro Northern Illinois University. 408164562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 408264562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 408364562Sgshapiro the Finnish Meteorological Institute. 408464562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 408564562Sgshapiro MAILLOCK when compiling. Also requires linking with 408664562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 408764562Sgshapiro University. 408864562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 408964562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 409064562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 409164562Sgshapiro University. 409264562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 409364562Sgshapiro structure to the beginning of the program. This ensures that 409464562Sgshapiro the getservbyname() is done before any seteuid to a possibly 409564562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 409664562Sgshapiro on a Solaris system, this avoids syslog messages such as, 409764562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 409864562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 409964562Sgshapiro University. 410064562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 410164562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 410264562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 410364562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 410464562Sgshapiro characters (in LMTP mode), mail.local split the incoming 410564562Sgshapiro line up into 2046-character output lines (excluding the 410664562Sgshapiro newline). If an input line was 2047 characters long 410764562Sgshapiro (excluding CR-LF) and the last character was a '.', 410864562Sgshapiro mail.local saw it as the end of input, transfered it to the 410964562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 411064562Sgshapiro If the message was much longer, both sendmail and 411164562Sgshapiro mail.local would deadlock waiting for each other to read 411264562Sgshapiro what they have written. Problem noted by Peter Jeremy of 411364562Sgshapiro Alcatel Australia Limited. 411464562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 411564562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 411664562Sgshapiro Neil Rickert of Northern Illinois University. 411764562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 411864562Sgshapiro timeout to avoid starvation. 411964562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 412064562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 412164562Sgshapiro Infinite Monkeys & Co. 412264562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 412364562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 412464562Sgshapiro printed in a machine readable fashion and the stats file 412564562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 412664562Sgshapiro of Maryland. 412764562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 412864562Sgshapiro generated maps to the TrustedUser as specified in the 412964562Sgshapiro sendmail configuration file. 413064562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 413164562Sgshapiro configuration file to use for finding the TrustedUser 413264562Sgshapiro option. 413364562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 413464562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 413564562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 413664562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 413764562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 413864562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 413964562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 414064562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 414164562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 414264562Sgshapiro Corporation UK. 414364562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 414464562Sgshapiro (e.g., sendmail would not drop root privileges if the 414564562Sgshapiro option was specified on the command line). Problem noted 414664562Sgshapiro by Todd C. Miller of Courtesan Consulting. 414764562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 414864562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 414964562Sgshapiro Institute for Global Communications. 415064562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 415164562Sgshapiro alias file(s) if the -f option is not used. Patch from 415264562Sgshapiro John Beck of Sun Microsystems. 415364562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 415464562Sgshapiro configuration file to use for finding alias file(s). Patch 415564562Sgshapiro from John Beck of Sun Microsystems. 415664562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 415764562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 415864562Sgshapiro of the Institute for Global Communications. 415964562Sgshapiro SMRSH: Update README for the new Build system. From Tim Pierce 416064562Sgshapiro of RootsWeb Genealogical Data Cooperative. 416164562Sgshapiro VACATION: Added vacation auto-responder to sendmail distribution. 416264562Sgshapiro LIBSMDB: Added abstracted database library. Works with Berkeley 416364562Sgshapiro DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM. 416464562Sgshapiro Changed Files: 416564562Sgshapiro The Build script in the various program subdirectories are 416664562Sgshapiro no longer symbolic links. They are now scripts 416764562Sgshapiro which execute the actual Build script in 416864562Sgshapiro devtools/bin. 416964562Sgshapiro All the manual pages are now written against -man and not 417064562Sgshapiro -mandoc as they were previously. 417164562Sgshapiro Add a simple Makefile to every directory so make instead 417264562Sgshapiro of Build will work (unless parameters are 417364562Sgshapiro required for Build). 417464562Sgshapiro New Directories: 417564562Sgshapiro devtools/M4/UNIX 417664562Sgshapiro include 417764562Sgshapiro libmilter 417864562Sgshapiro libsmdb 417964562Sgshapiro libsmutil 418064562Sgshapiro vacation 418164562Sgshapiro Renamed Directories: 418264562Sgshapiro BuildTools => devtools 418364562Sgshapiro src => sendmail 418464562Sgshapiro Deleted Files: 418564562Sgshapiro cf/m4/nullrelay.m4 418664562Sgshapiro devtools/OS/Linux.ppc 418764562Sgshapiro devtools/OS/ReliantUNIX 418864562Sgshapiro devtools/OS/SINIX 418964562Sgshapiro sendmail/ldap_map.h 419064562Sgshapiro New Files: 419164562Sgshapiro INSTALL 419264562Sgshapiro PGPKEYS 419364562Sgshapiro cf/cf/generic-linux.cf 419464562Sgshapiro cf/cf/generic-linux.mc 419564562Sgshapiro cf/feature/delay_checks.m4 419664562Sgshapiro cf/feature/dnsbl.m4 419764562Sgshapiro cf/feature/generics_entire_domain.m4 419864562Sgshapiro cf/feature/no_default_msa.m4 419964562Sgshapiro cf/feature/relay_mail_from.m4 420064562Sgshapiro cf/feature/virtuser_entire_domain.m4 420164562Sgshapiro cf/mailer/qpage.m4 420264562Sgshapiro cf/ostype/bsdi.m4 420364562Sgshapiro cf/ostype/hpux11.m4 420464562Sgshapiro cf/ostype/openbsd.m4 420564562Sgshapiro contrib/bounce-resender.pl 420664562Sgshapiro contrib/domainmap.m4 420764562Sgshapiro contrib/qtool.8 420864562Sgshapiro contrib/qtool.pl 420964562Sgshapiro devtools/M4/depend/AIX.m4 421064562Sgshapiro devtools/M4/list.m4 421164562Sgshapiro devtools/M4/string.m4 421264562Sgshapiro devtools/M4/subst_ext.m4 421364562Sgshapiro devtools/M4/switch.m4 421464562Sgshapiro devtools/OS/Darwin 421564562Sgshapiro devtools/OS/GNU 421664562Sgshapiro devtools/OS/SINIX.5.43 421764562Sgshapiro devtools/OS/SINIX.5.44 421864562Sgshapiro devtools/OS/m88k 421964562Sgshapiro devtools/bin/find_in_path.sh 422064562Sgshapiro mail.local/Makefile 422164562Sgshapiro mailstats/Makefile 422264562Sgshapiro makemap/Makefile 422364562Sgshapiro praliases/Makefile 422464562Sgshapiro rmail/Makefile 422564562Sgshapiro sendmail/Makefile 422664562Sgshapiro sendmail/bf.h 422764562Sgshapiro sendmail/bf_portable.c 422864562Sgshapiro sendmail/bf_portable.h 422964562Sgshapiro sendmail/bf_torek.c 423064562Sgshapiro sendmail/bf_torek.h 423164562Sgshapiro sendmail/shmticklib.c 423264562Sgshapiro sendmail/statusd_shm.h 423364562Sgshapiro sendmail/timers.c 423464562Sgshapiro sendmail/timers.h 423564562Sgshapiro smrsh/Makefile 423664562Sgshapiro vacation/Makefile 423790792Sgshapiro Renamed Files: 423864562Sgshapiro cf/ostype/gnuhurd.m4 => cf/ostype/gnu.m4 423964562Sgshapiro sendmail/cdefs.h => include/sendmail/cdefs.h 424064562Sgshapiro sendmail/sendmail.hf => sendmail/helpfile 424164562Sgshapiro sendmail/mailstats.h => include/sendmail/mailstats.h 424264562Sgshapiro sendmail/pathnames.h => include/sendmail/pathnames.h 424364562Sgshapiro sendmail/safefile.c => libsmutil/safefile.c 424464562Sgshapiro sendmail/snprintf.c => libsmutil/snprintf.c 424564562Sgshapiro sendmail/useful.h => include/sendmail/useful.h 424664562Sgshapiro cf/ostype/solaris2.m4 => cf/ostype/solaris2.pre5.m4 424764562Sgshapiro Copied Files: 424864562Sgshapiro cf/ostype/solaris2.ml.m4 => cf/ostype/solaris2.m4 424964562Sgshapiro 425064562Sgshapiro8.9.3/8.9.3 1999/02/04 425164562Sgshapiro SECURITY: Limit message headers to a maximum of 32K bytes (total 425264562Sgshapiro of all headers in a single message) to prevent a denial of 425364562Sgshapiro service attack.

Problem noted by 425864562Sgshapiro Jeff Wasilko of smoe.org. Fix from Booker Bense of 425964562Sgshapiro Stanford University and Per Hedeland of Ericsson. 426064562Sgshapiro Preserve the order of the MIME headers in multipart messages 426164562Sgshapiro when performing the MIME header length check. This 426264562Sgshapiro will allow PGP signatures to function properly. Problem 426364562Sgshapiro noted by Lars Hecking of University College, Cork, Ireland. 426464562Sgshapiro If ruleset 5 rewrote the local address to an :include: directive, 426564562Sgshapiro the delivery would fail with an "aliasing/forwarding loop 426664562Sgshapiro broken" error. Problem noted by Eric C Hagberg of Morgan 426764562Sgshapiro Stanley. Fix from Per Hedeland of Ericsson. 426864562Sgshapiro Allow -T to work for bestmx maps. Fix from Aaron Schrab of 426964562Sgshapiro ExecPC Internet Systems. 427064562Sgshapiro During the transfer of a message in an SMTP transaction, if a 427164562Sgshapiro TCP timeout occurs, the message would be properly queued 427264562Sgshapiro for later retry but the failure would be logged as 427364562Sgshapiro "Illegal Seek" instead of a timeout. Problem noted by 427464562Sgshapiro Piotr Kucharski of the Warsaw School of Economics (SGH) 427564562Sgshapiro and Carles Xavier Munyoz Baldo of CTV Internet. 427664562Sgshapiro Prevent multiple deliveries on a self-referencing alias if the 427764562Sgshapiro F=w mailer flag is not set. Problem noted by Murray S. 427864562Sgshapiro Kucherawy of Concentric Network Corporation and Per 427964562Sgshapiro Hedeland of Ericsson. 428064562Sgshapiro Do not strip empty headers but if there is no value and a 428164562Sgshapiro default is defined in sendmail.cf, use the default. 428264562Sgshapiro Problem noted by Philip Guenther of Gustavus Adolphus 428364562Sgshapiro College and Christopher McCrory of Netus, Inc. 428464562Sgshapiro Don't inherit information about the sender (notably the full name) 428564562Sgshapiro in SMTP (-bs) mode, since this might be called from inetd. 428664562Sgshapiro Accept any 3xx reply code in response to DATA command instead of 428764562Sgshapiro requiring 354. This change will match the wording to be 428864562Sgshapiro published in the updated SMTP specification from the DRUMS 428964562Sgshapiro group of the IETF. 429064562Sgshapiro Portability: 429164562Sgshapiro AIX 4.2.0 or 4.2.1 may become updated by the fileset 429264562Sgshapiro bos.rte.net level 4.2.0.2. This introduces the 429364562Sgshapiro softlink /usr/lib/libbind.a which should 429464562Sgshapiro not be used. It conflicts with the resolver 429564562Sgshapiro built into libc.a. "bind" has been removed 429664562Sgshapiro from the confLIBSEARCH BuildTools variable. 429764562Sgshapiro Users who have installed BIND 8.X will have 429864562Sgshapiro to add it back in their site.config.m4 file. 429964562Sgshapiro Problem noted by Ole Holm Nielsen of the 430064562Sgshapiro Technical University of Denmark. 430164562Sgshapiro CRAY TS 10.0.x from Sven Nielsen of San Diego 430264562Sgshapiro Supercomputer Center. 430364562Sgshapiro Improved LDAP version 3 integration based on input 430464562Sgshapiro from Kurt D. Zeilenga of the OpenLDAP Foundation, 430564562Sgshapiro John Beck of Sun Microsystems, and Booker Bense 430664562Sgshapiro of Stanford University. 430764562Sgshapiro Linux doesn't have a standard way to get the timezone 430864562Sgshapiro between different releases.

Users 463642575Speter which previously defined OLD_NEWDB=1 must now upgrade to the 463742575Speter current version of Berkeley DB. 463842575Speter Added support for regular expressions using the new map class regex. 463942575Speter From Jan Krueger of Unix-AG of University of Hannover. 464042575Speter Support for BIND 8.1.1's hesiod for hesiod maps and hesiod 464142575Speter UserDatabases from Randall Winchester of the University 464242575Speter of Maryland. 464342575Speter Allow any shell for user shell on program deliveries on V1 464464562Sgshapiro configurations for backwards compatibility on machines which 464542575Speter do not have getusershell(). Fix from John Beck of Sun 464642575Speter Microsystems. 464742575Speter On operating systems which change the process title by reusing the 464842575Speter argument vector memory, sendmail could corrupt memory if the 464942575Speter last argument was either "-q" or "-d". Problem noted by 465042575Speter Frank Langbein of the University of Stuttgart. 465142575Speter Support Local Mail Transfer Protocol (LMTP) between sendmail and 465242575Speter mail.local on the F=z flag. 465342575Speter Macro-expand the contents of the ErrMsgFile. Previously this was 465442575Speter only done if you had magic characters (0x81) to indicate 465542575Speter macro expansion. Now $x will be expanded. This means that 465642575Speter real dollar signs have to be backslash escaped. 465742575Speter TCP Wrappers expects "unknown" in the hostname argument if the 465842575Speter reverse DNS lookup for the incoming connection fails. 465942575Speter Problem noted by Randy Grimshaw of Syracuse University and 466042575Speter Wietse Venema of the Global Security Analysis Lab at 466142575Speter IBM T.J. Watson Research. 466242575Speter DSN success bounces generated from an invocation of sendmail -t 466342575Speter would be sent to both the sender and MAILER-DAEMON. 466442575Speter Problem noted by Claus Assmann of 466542575Speter Christian-Albrechts-University of Kiel. 466642575Speter Avoid "Error 0" messages on delivery mailers which exit with a 466742575Speter valid exit value such as EX_NOPERM. Fix from Andreas Luik 466842575Speter of ISA Informationssysteme GmbH. 466942575Speter Tokenize $&x expansions on right hand side of rules. This eliminates 467042575Speter the need to use tricks like $(dequote "" $&{client_name} $) 467142575Speter to cause the ${client_name} macro to be properly tokenized. 467242575Speter Add the MaxRecipientsPerMessage option: this limits the number of 467364562Sgshapiro recipients that will be accepted in a single SMTP 467442575Speter transaction. After this number is reached, sendmail 467542575Speter starts returning "452 Too many recipients" to all RCPT 467642575Speter commands. This can be used to limit the number of recipients 467764562Sgshapiro per envelope (in particular, to discourage use of the server 467838032Speter for spamming). Note: a better approach is to restrict 467938032Speter relaying entirely. 468038032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 468138032Speter to ldapx map and added timeout for ldap_open call to 468238032Speter avoid hanging sendmail in the event of hung LDAP servers. 468338032Speter Patch from Booker Bense of Stanford University. 468438032Speter Allow multiple -qI, -qR, or -qS queue run limiters. For example, 468538032Speter '-qRfoo -qRbar' would deliver mail to recipients with foo or 468638032Speter bar in their address. Patch from Allan E Johannesen of 468738032Speter Worcester Polytechnic Institute. 468838032Speter The bestmx map will now return a list of the MX servers for a host if 468938032Speter passed a column delimiter via the -z map flag. This can be 469038032Speter used to check if the server is an MX server for the recipient 469138032Speter of a message. This can be used to help prevent relaying. 469238032Speter Patch from Mitchell Blank Jr of Exec-PC. 469338032Speter Mark failures for the *file* mailer and return bounce messages to the 469438032Speter sender for those failures. 469538032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 469638032Speter preserving the TZ environment variable until TimeZoneSpec 469738032Speter has been determined. Problem noted by Ralf Hildebrandt of 469864562Sgshapiro Technical University of Braunschweig. Patch from Per Hedeland 469938032Speter of Ericsson. 470038032Speter Print test input in address test mode when input is not from the tty 470164562Sgshapiro when the -v flag is given (i.e., sendmail -bt -v) to make 470238032Speter output easier to decipher. Problem noted by Aidan Nichol 470338032Speter of Procter & Gamble. 470438032Speter The LDAP map -s flag was not properly parsed and the error message 470543730Speter given included the remainder of the arguments instead of 470638032Speter solely the argument in error. Problem noted by Aidan Nichol 470738032Speter of Procter & Gamble. 470838032Speter New DontBlameSendmail option. This option allows administrators to 470938032Speter bypass some of sendmail's file security checks at the expense 471038032Speter of system security. This should only be used if you are 471138032Speter absolutely sure you know the consequences. The available 471238032Speter DontBlameSendmail options are: 471338032Speter Safe 471438032Speter AssumeSafeChown 471538032Speter ClassFileInUnsafeDirPath 471638032Speter ErrorHeaderInUnsafeDirPath 471738032Speter GroupWritableDirPathSafe 471838032Speter GroupWritableForwardFileSafe 471938032Speter GroupWritableIncludeFileSafe 472038032Speter GroupWritableAliasFile 472138032Speter HelpFileinUnsafeDirPath 472238032Speter WorldWritableAliasFile 472338032Speter ForwardFileInGroupWritableDirPath 472438032Speter IncludeFileInGroupWritableDirPath 472538032Speter ForwardFileInUnsafeDirPath 472638032Speter IncludeFileInUnsafeDirPath 472738032Speter ForwardFileInUnsafeDirPathSafe 472838032Speter IncludeFileInUnsafeDirPathSafe 472938032Speter MapInUnsafeDirPath 473038032Speter LinkedAliasFileInWritableDir 473138032Speter LinkedClassFileInWritableDir 473238032Speter LinkedForwardFileInWritableDir 473338032Speter LinkedIncludeFileInWritableDir 473438032Speter LinkedMapInWritableDir 473538032Speter LinkedServiceSwitchFileInWritableDir 473638032Speter FileDeliveryToHardLink 473738032Speter FileDeliveryToSymLink 473838032Speter WriteMapToHardLink 473938032Speter WriteMapToSymLink 474038032Speter WriteStatsToHardLink 474138032Speter WriteStatsToSymLink 474238032Speter RunProgramInUnsafeDirPath 474338032Speter RunWritableProgram 474438032Speter New DontProbeInterfaces option to turn off the inclusion of all the 474538032Speter interface names in $=w on startup. In particular, if you 474638032Speter have lots of virtual interfaces, this option will speed up 474738032Speter startup. However, unless you make other arrangements, mail 474838032Speter sent to those addresses will be bounced. 474938032Speter Automatically create alias databases if they don't exist and 475038032Speter AutoRebuildAliases is set. 475138032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 475238032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 475338032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 475438032Speter When determining the client host name ($&{client_name} macro), do 475538032Speter a forward (A) DNS lookup on the result of the PTR lookup 475638032Speter and compare results. If they differ or if the PTR lookup 475738032Speter fails, &{client_name} will contain the IP address 475838032Speter surrounded by square brackets (e.g., [127.0.0.1]). 475942575Speter New map flag: -Tx appends "x" to lookups that return temporary failure 476042575Speter (i.e, it is like -ax for the temporary failure case, in 476138032Speter contrast to the success case). 476264562Sgshapiro New syntax to do limited checking of header syntax. A config line 476338032Speter of the form: 476438032Speter HHeader: $>Ruleset 476538032Speter causes the indicated Ruleset to be invoked on the Header 476664562Sgshapiro when read. This ruleset works like the check_* rulesets -- 476738032Speter that is, it can reject mail on the basis of the contents. 476838032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 476938032Speter from hiding their connection information in Received: 477038032Speter headers. 477138032Speter When SingleThreadDelivery is active, deliveries to locked hosts 477238032Speter are skipped. This will cause the delivering process to 477338032Speter try the next MX host or queue the message if no other MX 477438032Speter hosts are available. Suggested by Alexander Litvin. 477538032Speter The [FILE] mailer type now delivers to the file specified in the 477638032Speter A= equate of the mailer definition instead of $u. It also 477738032Speter obeys all of the F= mailer flags such as the MIME 477838032Speter 7/8 bit conversion flags. This is useful for defining 477938032Speter a mailer which delivers to the same file regardless of the 478038032Speter recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 478138032Speter Do not assume the identity of a remote connection is root@localhost 478238032Speter if the remote connection closes the socket before the 478338032Speter remote identity can be queried. 478438032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 478538032Speter Some mailers, including procmail, require that the real 478638032Speter uid is left unchanged by sendmail. Problem noted by Per 478738032Speter Hedeland of Ericsson. 478838032Speter No longer is the src/obj*/Makefile selected from a large list -- it 478938032Speter is now generated using the information in BuildTools/OS/ -- 479038032Speter some of the details are determined dynamically via 479138032Speter BuildTools/bin/configure.sh. 479290792Sgshapiro The other programs in the sendmail distribution -- mail.local, 479338032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 479438032Speter the new Build method which creates an operating system 479538032Speter specific Makefile using the information in BuildTools. 479638032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 479738032Speter a failure on one message won't affect future messages to the 479838032Speter same host). This is necessary if the remote host sends 479938032Speter a 451 error if the domain of the sender does not resolve 480038032Speter as is common in anti-spam configurations. Problem noted 480138032Speter by Mitchell Blank Jr of Exec-PC. 480238032Speter New "discard" mailer for check_* rulesets and header checking 480338032Speter rulesets. If one of the above rulesets resolves to the 480438032Speter $#discard mailer, the commands will be accepted but the 480538032Speter message will be completely discarded after it is accepting. 480638032Speter This means that even if only one of the recipients 480738032Speter resolves to the $#discard mailer, none of the recipients 480838032Speter will receive the mail. Suggested by Brian Kantor. 480938032Speter All but the last cloned envelope of a split envelope were queued 481038032Speter instead of being delivered. Problem noted by John Caruso 481138032Speter of CNET: The Computer Network. 481238032Speter Fix deadlock situation in persistent host status file locking. 481338032Speter Syslog an error if a user forward file could not be read due to 481438032Speter an error. Patch from John Beck of Sun Microsystems. 481538032Speter Use the first name returned on machine lookups when canonifying a 481638032Speter hostname via NetInfo. Patch from Timm Wetzel of GWDG. 481738032Speter Clear the $&{client_addr}, $&{client_name}, and $&{client_port} 481838032Speter macros when delivering a bounce message to prevent 481938032Speter rejection by a check_compat ruleset which uses these macros. 482064562Sgshapiro Problem noted by Jens Hamisch of AgiX Internetservices GmbH. 482138032Speter If the check_relay ruleset resolves to the the error mailer, the 482238032Speter error in the $: portion of the resolved triplet is used 482338032Speter in the rejection message given to the remote machine. 482438032Speter Suggested by Scott Gifford of The Internet Ramp. 482538032Speter Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros 482638032Speter before calling the check_relay ruleset. Suggested by Scott 482738032Speter Gifford of The Internet Ramp. 482838032Speter Sendmail would get a segmentation fault if a mailer exited with an 482938032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 483038032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 483138032Speter Institute. 483238032Speter Separate snprintf/vsnprintf routines into separate file for use by 483338032Speter mail.local. 483438032Speter Allow multiple map lookups on right hand side, e.g., 483538032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 483638032Speter Christophe Wolfhugel of the Pasteur Institute. 483738032Speter Properly generate success DSN messages if requested for aliases 483838032Speter which have owner- aliases. Problem noted by Kari Hurtta 483938032Speter of the Finnish Meteorological Institute. 484038032Speter Properly display delayed-expansion macros ($&{macroname}) in 484138032Speter address test mode (-bt). Problem noted by Bryan Costales 484238032Speter of InfoBeat, Inc. 484338032Speter -qR could sometimes match names incorrectly. Problem noted by 484438032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 484538032Speter Include a magic number and version in the StatusFile for the 484638032Speter mailstats command. 484738032Speter Record the number of rejected and discarded messages in the 484838032Speter StatusFile for display by the mailstats command. Patch 484938032Speter from Randall Winchester of the University of Maryland. 485038032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 485138032Speter user portion as IDENT:username@site instead of 485238032Speter username@site to differentiate the two. Suggested by 485338032Speter Kari Hurtta of the Finnish Meteorological Institute. 485438032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 485538032Speter Ericsson. 485638032Speter Change persistent host status filename substitution so '/' is 485738032Speter replaced by ':' instead of '|' to avoid clashes. Also 485838032Speter avoid clashes with hostnames with leading dots. Fix from 485938032Speter Mitchell Blank Jr. of Exec-PC. 486038032Speter If the system lock table is full, only attempt to create a new 486138032Speter queue entry five times before giving up. Previously, it 486238032Speter was attempted indefinitely which could cause the partition 486338032Speter to run out of inodes. Problem noted by Suzie Weigand of 486464562Sgshapiro Stratus Computer, Inc. 486538032Speter In verbose mode, warn if the sendmail.cf version is less than the 486638032Speter currently supported version. 486738032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 486864562Sgshapiro from Randall S.

Patch from 491438032Speter Robert Harker of Harker Systems. 491538032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 491638032Speter directory for certain programs. 491738032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 491838032Speter local mail delivery. By the default, /usr/libexec/mail.local 491938032Speter is used. This is expected to be the mail.local shipped 492038032Speter with 8.9 which is LMTP capable. The path is based on the 492164562Sgshapiro new confEBINDIR m4 variable. 492238032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 492338032Speter FEATURE(smrsh). Note that this changes the default from 492438032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 492538032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 492638032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 492738032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 492838032Speter the user to setup different .forward files for 492938032Speter user+detail addressing. 493038032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 493138032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 493238032Speter DontProbeInterfaces, and DontBlameSendmail options. 493338032Speter CONFIG: by default do not allow relaying (that is, accepting mail 493438032Speter from outside your domain and sending it to another host 493538032Speter outside your domain). 493638032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 493738032Speter any site to any site. 493838032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 493938032Speter domain as defined by the 'm' class ($=m) to relay. 494038032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 494138032Speter the MX records of the host portion of an incoming recipient. 494238032Speter CONFIG: new FEATURE(access_db) which turns on the access database 494364562Sgshapiro feature. This database gives you the ability to allow 494438032Speter or refuse to accept mail from specified domains for 494538032Speter administrative reasons. By default, names that are listed 494638032Speter as "OK" in the access db are domain names, not host names. 494738032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 494838032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 494938032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 495038032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 495138032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 495238032Speter of FEATURE(access_db) and class 'R' to lookup individual 495338032Speter host names only. 495438032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 495538032Speter using % addressing is used, e.g. user%site@othersite, 495638032Speter and othersite is in class 'R', the check_rcpt ruleset 495738032Speter will strip @othersite and recheck user@site for relaying. 495838032Speter This feature changes that behavior.

Problem noted by Greg Nichols of Wind 513938032Speter River Systems. 514038032Speter If SingleThreadDelivery was enabled and the remote server returned a 514138032Speter protocol error on the DATA command, the connection would be 514238032Speter closed but the persistent host status file would not be 514338032Speter unlocked so other sendmail processes could not deliver to 514438032Speter that host. Problem noted by Peter Wemm of DIALix. 514538032Speter If queueing up a message due to an expensive mailer, don't increment 514638032Speter the number of delivery attempts or set the last delivery 514738032Speter attempt time so the message will be delivered on the next 514838032Speter queue run regardless of MinQueueAge. Problem noted by 514938032Speter Brian J. Coan of the Institute for Global Communications. 515038032Speter Authentication warnings of "Processed from queue _directory_" and 515138032Speter "Processed by _username_ with -C _filename_" would be logged 515238032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 515338032Speter of the Finnish Meteorological Institute. 515438032Speter Use a better heuristic for detecting GDBM. 515538032Speter Log null connections on dropped connections. Problem noted by 515638032Speter Jon Lewis of Florida Digital Turnpike. 515738032Speter If class dbm maps are rebuilt, sendmail will now detect this and 515838032Speter reopen the map. Previously, they could give stale 515938032Speter results during a single message processing (but would 516038032Speter recover when the next message was received). Fix from 516138032Speter Joe Pruett of Q7 Enterprises. 516238032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 516338032Speter requests. Problem noted by Kari E.

Problem noted by Kari E. Hurtta of the 516838032Speter Finnish Meteorological Institute. 516938032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 517038032Speter sendmail via a UNIX pipe. This will allow rulesets using 517138032Speter $&{client_name} to process without sending the string through 517238032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 517338032Speter A combination of deferred delivery mode, a double bounce situation, 517464562Sgshapiro and the inability to save a bounce message to 517538032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 517638032Speter to postmaster but not remove the offending envelope from the 517738032Speter queue causing it to create a new bounce message each time the 517838032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 517938032Speter Associates. 518038032Speter Remove newlines from hostname information returned via DNS. There are 518138032Speter no known security implications of newlines in hostnames as 518238032Speter sendmail filters newlines in all vital areas; however, this 518338032Speter could cause confusing error messages. 518438032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 518538032Speter rejected if any of the specified addresses were bad. This 518638032Speter behavior was modified to only reject the bad addresses and not 518738032Speter the entire message. Problem noted by Jozsef Hollosi of 518838032Speter SuperNet, Inc. 518938032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 519038032Speter Bryan Costales of InfoBeat, Inc. 519138032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 519238032Speter mailers. Problem noted by Kari E. Hurtta of the 519338032Speter Finnish Meteorological Institute. 519438032Speter An error in calculating the available space in the list of addresses 519538032Speter for logging deliveries could cause an address to be silently 519638032Speter dropped. 519738032Speter Include the initial user environment if sendmail is restarted via 519838032Speter a HUP signal. This will give room for the process title. 519938032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 520038032Speter Mail could be delivered without a body if the machine does not 520138032Speter support flock locking and runs out of processes during 520238032Speter delivery. Fix from Chuck Lever of the University of Michigan. 520338032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 520438032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 520538032Speter Institute. 520638032Speter Make sure non-rebuildable database maps are opened before the 520738032Speter rebuildable maps (i.e., alias files) in case the database maps 520838032Speter are needed for verifying the left hand side of the aliases. 520938032Speter Problem noted by Lloyd Parkes of Victoria University. 521038032Speter Make sure sender RFC822 source route addresses are alias expanded for 521138032Speter bounce messages. Problem noted by Juergen Georgi of 521238032Speter RUS University of Stuttgart. 521338032Speter Minor lint fixes. 521438032Speter Return a temporary error instead of a permanent error if an LDAP map 521538032Speter search returns an error. This will allow sequenced maps which 521638032Speter use other LDAP servers to be checked. Fix from Booker Bense 521738032Speter of Stanford University. 521838032Speter When automatically converting from quoted printable to 8bit text do 521938032Speter not pad bare linefeeds with a space.

Patch from Raymund Will of LST Software 526638032Speter GmbH. 526738032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 526838032Speter Problem noted by Fredrik J�nsson of the Royal Institute 526938032Speter of Technology, Stockholm. 527038032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 527138032Speter some environments could give "multiple definitions" for these 527238032Speter routines during compilation. If using TCP Wrappers, assume 527338032Speter that these routines are included as though they were in the 527438032Speter C library. Patch from Robert La Ferla. 527538032Speter When a NEWDB database map was rebuilt at the same time it was being 527638032Speter used by a queue run, the maps could be left locked for the 527738032Speter duration of the queue run, causing other processes to hang. 527838032Speter Problem noted by Kendall Libby of Shore.NET. 527938032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 528038032Speter mail was passed on without any recipient header. This could 528138032Speter cause problems downstream. Problem noted by Xander Jansen 528238032Speter of SURFnet ExpertiseCentrum. 528338032Speter Give error when GDBM is used with sendmail. GDBM's locking and 528464562Sgshapiro linking of the .dir and .pag files interferes with sendmail's 528538032Speter locking and security checks. Problems noted by Fyodor 528638032Speter Yarochkin of the Kyrgyz Republic FreeNet. 528738032Speter Don't fsync qf files if SuperSafe option is not set. 528838032Speter Avoid extra calls to gethostbyname for addresses for which a 528938032Speter gethostbyaddr found no value. Also, ignore any returns 529038032Speter from gethostbyaddr that look like a dotted quad. 529138032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 529238032Speter "may be forged", since at the network level we pretty much 529338032Speter have to assume that the information is good. 529438032Speter In some cases, errors during an SMTP session could leave files 529538032Speter open or locked. 529638032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 529738032Speter Better handling of non-set-user-ID binaries -- avoids certain obnoxious 529838032Speter errors during testing. 529938032Speter Errors in file locking of NEWDB maps had the incorrect file name 530038032Speter printed in the error message. 530138032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 530238032Speter missing parameter were issued, the EHLO behaved like a HELO. 530338032Speter Load limiting never kicked in for incoming SMTP transactions if the 530438032Speter DeliveryMode=background and any recipient was an alias or 530538032Speter had a .forward file. From Nik Conwell of Boston University. 530638032Speter On some non-Posix systems, the decision of whether chown(2) permits 530738032Speter file giveaway was undefined. From Tetsu Ushijima of the 530838032Speter Tokyo Institute of Technology. 530938032Speter Fix race condition that could cause the body of a message to be 531038032Speter lost (so only the header was delivered). This only occurs 531138032Speter on systems that do not use flock(2), and only when a queue 531238032Speter runner runs during a critical section in another message 531338032Speter delivery. Based on a patch from Steve Schweinhart of 531438032Speter Results Computing. 531538032Speter If a qf file was found in a mail queue directory that had a problem 531638032Speter (wrong ownership, bad format, etc.) and the file name was 531738032Speter exactly MAXQFNAME bytes long, then instead of being tried 531838032Speter once, it would be tried on every queue run. Problem noted 531938032Speter by Bryan Costales of Mercury Mail. 532038032Speter If the system supports an st_gen field in the status structure, 532138032Speter include it when reporting that a file has changed after open. 532238032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 532338032Speter This out to be checked as well as reported, since it is 532438032Speter theoretically possible for an attacker to remove a file after 532538032Speter it is opened and replace it with another file that has the 532638032Speter same i-number, but some filesystems (notably AFS) return 532738032Speter garbage in this field, and hence always look like the file 532838032Speter has changed. As a practical matter this is not a security 532938032Speter problem, since the files can be neither hard nor soft links, 533038032Speter and on no filesystem (that I am aware of) is it possible to 533138032Speter have two files on the same filesystem with the same i-number 533238032Speter simultaneously. 533338032Speter Delete the root Makefile from the distribution -- it is only for 533438032Speter use internally, and does not work at customer sites. 533538032Speter Fix botch that caused the second MAIL FROM: command in a single 533638032Speter transaction to clear the entire transaction. Problem 533738032Speter noted by John Kennedy of Cal State University, Chico. 533838032Speter Work properly on machines that have _PATH_VARTMP defined without 533938032Speter a trailing slash.

This makes it possible to create a root 542238032Speter owned file in an arbitrary directory by inserting the symlink 542364562Sgshapiro into a writable directory after the initial lstat(2) check 542438032Speter determined that the file did not exist. The only verified 542538032Speter example of a system having these odd semantics for O_EXCL 542638032Speter and symbolic links was HP-UX prior to version 9.07. Most 542738032Speter systems do not have the problem, since a exclusive create 542838032Speter of a file disallows symbolic links. Systems that have been 542938032Speter verified to NOT have the problem include AIX 3.x, *BSD, 543038032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 543138032Speter and Ultrix. This is a potential exposure on systems that 543238032Speter have this bug and which do not have a MAILER-DAEMON alias 543338032Speter pointing at a legitimate account, since this will cause old 543438032Speter mail to be dropped in /var/tmp/dead.letter. 543538032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 543638032Speter if maps or alias files are in world writable directories. 543738032Speter If your system has alias maps in writable directories, it 543838032Speter is potentially possible for an attacker to replace the .db 543938032Speter (or .dir and .pag) files by symbolic links pointing at 544038032Speter another database; this can be used either to expose 544138032Speter information (e.g., by pointing an alias file at /etc/spwd.db 544238032Speter and probing for accounts), or as a denial-of-service attack 544338032Speter (by trashing the password database). The fix disallows 544438032Speter symbolic links entirely when rebuilding alias files or on 544538032Speter maps that are in writable directories, and always warns on 544638032Speter writable directories; 8.9 will probably consider writable 544738032Speter directories to be fatal errors. This does not represent an 544838032Speter exposure on systems that have alias files in unwritable 544938032Speter system directories. 545038032Speter SECURITY: disallow .forward or :include: files that are links (hard 545138032Speter or soft) if the parent directory (or any directory in the 545238032Speter path) is writable by anyone other than the owner. This is 545338032Speter similar to the previous case for user files. This change 545438032Speter should not affect most systems, but is necessary to prevent 545538032Speter an attacker who can write the directory from pointing such 545638032Speter files at other files that are readable only by the owner. 545738032Speter SECURITY: Tighten safechown rules: many systems will say that they 545838032Speter have a safe (restricted to root) chown even on files that 545938032Speter are mounted from another system that allows owners to give 546090792Sgshapiro away files. The new rules are very strict, trusting file 546138032Speter ownership only in those few cases where the system has 546238032Speter been verified to be at least as paranoid as necessary. 546338032Speter However, it is possible to relax the rules to partially 546438032Speter trust the ownership if the directory path is not world or 546538032Speter group writable. This might allow someone who has a legitimate 546638032Speter :include: file (referenced directly from /etc/aliases) to 546743730Speter become another non-root user if the :include: file is in a 546838032Speter non-writable directory on an NFS-mounted filesystem where 546938032Speter the local system says that giveaway is denied but it is 547038032Speter actually permitted. I believe this to be a very small set 547138032Speter of cases. If in doubt, do not point :include: aliases at 547238032Speter NFS-mounted filesystems. 547338032Speter SECURITY: When setting a numeric group id using the RunAsUser option 547438032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 547538032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 547638032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 547738032Speter The user id was still set properly. Problem noted by Uli 547838032Speter Pralle of the Technical University of Berlin. 547938032Speter Save the initial gid set for use when checking for if the 548038032Speter PrivacyOptions=restrictmailq option is set. Problem reported 548138032Speter by Wolfgang Ley of DFN-CERT. 548238032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 548338032Speter failure on one message won't affect future messages to the 548438032Speter same host). 548538032Speter IP source route printing had an "off by one" error that would 548638032Speter affect any options that came after the route option. Patch 548738032Speter from Theo de Raadt. 548838032Speter The "Message is too large" error didn't successfully bounce the error 548938032Speter back to the sender. Problem reported by Stephen More of 549038032Speter PSI; patch from Gregory Neil Shapiro of WPI. 549138032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 549238032Speter of 5.1.3); it apparently gets used in multiple ways. 549338032Speter Suggested by John Myers of Portola Communications. 549438032Speter Fix possible extra null byte generated during collection if errors 549538032Speter occur at the beginning of the stream. Patch contributed by 549638032Speter Andrey A. Chernov and Gregory Neil Shapiro. 549738032Speter Code changes to avoid possible reentrant call of malloc/free within 549838032Speter a signal handler. Problem noted by John Beck of Sun 549938032Speter Microsystems. 550038032Speter Move map initialization to be earlier so that check_relay ruleset 550138032Speter will have the latest version of the map data. Problem noted 550238032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 550338032Speter If there are fatal errors during the collection phase (e.g., message 550438032Speter too large) don't send the bogus message. 550538032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 550638032Speter have errors and have owner- aliases. Problem noted by Michael 550738032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 550838032Speter Avoid null pointer dereference on illegal Boundary= parameters in 550938032Speter multipart/mixed Content-Type: header. Problem noted by 551038032Speter Richard Muirden of RMIT University. 551138032Speter Always print error messages during newaliases (-bi) even if the 551238032Speter ErrorMode is not set to "print". Fix from Gregory Neil 551338032Speter Shapiro. 551438032Speter Test mode could core dump if you did a /map lookup in an optional map 551538032Speter that could not be opened. Based on a fix from John Beck of 551638032Speter Sun Microsystems. 551738032Speter If DNS is misconfigured so that the last MX record tried points to 551838032Speter a host that does not have an A record, but other MX records 551938032Speter pointed to something reasonable, don't bounce the message 552038032Speter with a "host unknown" error. Note that this should really 552138032Speter be fixed in the zone file for the domain. Problem noted by 552238032Speter Joe Rhett of Navigist, Inc. 552338032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 552438032Speter the message as having been tried; otherwise the next queue 552538032Speter run will not realize that this is a second attempt and will 552638032Speter retry immediately. Problem noted by Bryan Costales of 552738032Speter Mercury Mail. 552838032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 552938032Speter will be run until the later setting of the clock is reached. 553038032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 553138032Speter Morgan Stanley. 553238032Speter If the load average rises above the cutoff threshold (above which 553338032Speter sendmail will not process the queue at all) during a queue 553438032Speter run, abort the queue run immediately. Problem noted by 553538032Speter Bryan Costales of Mercury Mail. 553638032Speter The variable queue processing algorithm (based on the message size, 553738032Speter number of recipients, message precedence, and job age) was 553838032Speter non-functional -- either the entire queue was processed or 553938032Speter none of the queue was processed. The updated algorithm 554038032Speter does no queue run if a single recipient zero size job will 554138032Speter not be run. 554238032Speter If there is a fatal ("panic") message that will cause sendmail to 554338032Speter die immediately, never hold the error message for future 554438032Speter printing. 554538032Speter Force ErrorMode=print in -bt mode so that all errors are printed 554638032Speter regardless of the setting of the ErrorMode option in the 554738032Speter configuration file. Patch from Gregory Neil Shapiro. 554838032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 554938032Speter routine available in one of the libraries. Use it in conf.h. 555038032Speter The -m (match only) flag now works on host class maps. 555138032Speter If class hash or btree maps are rebuilt, sendmail will now detect 555238032Speter this and reopen the map. Previously, they could give 555338032Speter erroneous results during a single message processing 555438032Speter (but would recover when the next message was received). 555538032Speter Don't delete zero length queue files when doing queue runs until the 555638032Speter files are at least ten minutes old. This avoids a potential 555738032Speter race condition: the creator creates the qf file, getting back 555838032Speter a file descriptor. The queue runner locks it and deletes it 555938032Speter because it is zero length. The creator then writes the 556038032Speter descriptor that is now for a disconnected file, and the 556138032Speter job goes away. Based on a suggestion by Bryan Costales. 556238032Speter When determining the "validated" host name ($_ macro), do a forward 556338032Speter (A) DNS lookup on the result of the PTR lookup and compare 556438032Speter results. If they differ or if the PTR lookup fails, tag the 556538032Speter address as "may be forged". 556638032Speter Log null connections (i.e., hosts that connect but do not do any 556738032Speter substantive activity on the connection before disconnecting; 556838032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 556938032Speter Always permit "writes" to /dev/null regardless of the link count. 557038032Speter This is safe because /dev/null is special cased, and no open 557138032Speter or write is ever actually attempted. Patch from Villy Kruse 557238032Speter of TwinCom. 557338032Speter If a message cannot be sent because of a 552 (exceeded storage 557438032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 557564562Sgshapiro was given, don't return the body in the bounce, since there 557638032Speter is a very good chance that the message will double-bounce. 557738032Speter Fix possible line truncation if a quoted-printable had an =00 escape 557838032Speter in the body. Problem noted by Charles Karney of the Princeton 557938032Speter Plasma Physics Laboratory. 558038032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 558138032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 558238032Speter Institute. 558338032Speter The MaxDaemonChildren option wasn't applying to queue runs as 558438032Speter documented. Note that this increases the potential denial 558538032Speter of service problems with this option: an attacker can 558638032Speter connect many times, and thereby lock out queue runs as well 558738032Speter as incoming connections. If you use this option, you should 558838032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 558938032Speter to avoid this attack. Failure to limit noted by Matthew 559038032Speter Dillon of BEST Internet Communications. 559138032Speter Always give a message in newaliases if alias files cannot be 559238032Speter opened instead of failing silently. Suggested by Gregory 559338032Speter Neil Shapiro. This change makes the code match the O'Reilly 559438032Speter book (2nd edition). 559538032Speter Some older versions of the resolver could return with h_errno == -1 559638032Speter if no name server could be reached, causing mail to bounce 559738032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 559838032Speter John Beck of SunSoft. 559938032Speter If a :include: file is owned by a user that does not have an entry 560038032Speter in the passwd file, sendmail could dereference a null pointer. 560138032Speter Problem noted by Satish Mynam of Sun Microsystems. 560238032Speter Take precautions to make sure that the SMTP protocol cannot get out 560338032Speter of sync if (for example) an alias file cannot be opened. 560438032Speter Fix a possible race condition that can cause a SIGALRM to come in 560538032Speter immediately after a SIGHUP, causing the new sendmail to die. 560638032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 560738032Speter from Villy Kruse of TwinCom. 560838032Speter Ignore improperly formatted SMTP reply codes. Previously these were 560938032Speter partially processed, which could cause confusing error 561038032Speter returns. 561138032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 561238032Speter on some architectures. 561338032Speter Portability: 561438032Speter A/UX: from Jim Jagielski of NASA/GSFC. 561538032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 561638032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 561738032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 561838032Speter defined. Problem reported by A Sun of the University 561938032Speter of Washington. 562038032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 562138032Speter the system rather than guessing at compile time. 562238032Speter Patch contributed by John Beck of Sun Microsystems. 562338032Speter Intel Paragon: from Wendy Lin of Purdue University. 562438032Speter GNU Hurd: from Miles Bader of the GNU project. 562538032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 562638032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 562738032Speter Unfortunately releasing them opens a race condition, 562838032Speter but there appears to be no fix for this.

From 563738032Speter Kari Hurtta. 563838032Speter IRIX 6.x: Create Makefiles for systems that claim to be 563938032Speter IRIX64 but are 6.2 or higher (so use the regular 564038032Speter IRIX Makefile). 564138032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 564238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 564338032Speter CONFIG: Some canonification was still done for UUCP-like addresses 564438032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 564538032Speter Brian Candler. 564638032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 564738032Speter local names as local. Problem noted by Jeff Polk of BSDI; 564838032Speter fix provided by Gregory Neil Shapiro. 564938032Speter CONFIG: The "local:user" syntax entries in mailertables and other 565038032Speter "mailer:user" syntax locations returned an incorrect value 565138032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 565238032Speter CONFIG: Retain "+detail" information when forwarding mail to a 565338032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 565438032Speter Guenther of Gustavus Adolphus College. 565538032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 565638032Speter rules are the same as for aliasing. Based on a patch from 565738032Speter Gregory Neil Shapiro. 565838032Speter CONFIG: Break up parsing rules into several pieces; this should 565938032Speter have no functional change in this release, but makes it 566038032Speter possible to have better anti-spam rulesets in the future. 566138032Speter CONFIG: Disallow double dots in host names to avoid having the 566238032Speter HostStatusDirectory store status under the wrong name. 566338032Speter In some cases this can be used as a denial-of-service attack. 566438032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 566538032Speter Gregory Neil Shapiro. 566638032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 566738032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 566838032Speter don't include From_, and convert to 8-bit). Suggestions 566938032Speter from Kimmo Suominen and Roderick Schertler. 567038032Speter CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 567138032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 567238032Speter was specified, even when it wasn't. 567338032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 567438032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 567538032Speter "slip in" a symbolic link between the lstat(2) call and the 567638032Speter exclusive open. This is only a problem on System V derived 567738032Speter systems that allow an exclusive create on files that are 567838032Speter symbolic links pointing nowhere. 567938032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 568038032Speter not reset back to root, which on some systems would cause 568138032Speter later mailboxes to fail. Also, any partial message would 568238032Speter not be truncated, which could result in repeated deliveries. 568338032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 568438032Speter developers). 568538032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 568638032Speter change to the sendmail map code was made in 8.8.3. Problem 568738032Speter noted by Gregory Neil Shapiro. 568838032Speter MAKEMAP: Give warnings on file problems such as map files that are 568938032Speter symbolic links; although makemap is not set-user-ID root, it is 569038032Speter often run as root and hence has the potential for the same 569138032Speter sorts of problems as alias rebuilds. 569238032Speter MAKEMAP: Change compilation so that it will link properly on 569338032Speter NEXTSTEP. 569438032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 569538032Speter Accept an optional list of arguments following the server 569638032Speter name for the ETRN arguments to use (instead of $=w). Other 569738032Speter miscellaneous bug fixes. From Christian von Roques via 569838032Speter John Beck of Sun Microsystems. 569938032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 570038032Speter Perl script converts GECOS information in the /etc/passwd 570138032Speter file into aliases, allowing for faster access to full name 570238032Speter lookups; it is also clever about adding aliases (to root) 570338032Speter for system accounts. 570438032Speter NEW FILES: 570538032Speter src/safefile.c 570638032Speter cf/ostype/gnuhurd.m4 570738032Speter cf/ostype/irix6.m4 570838032Speter contrib/passwd-to-alias.pl 570938032Speter src/Makefiles/Makefile.IRIX64.6.1 571038032Speter src/Makefiles/Makefile.IRIX64.6.x 571138032Speter RENAMED FILES: 571238032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 571338032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 571438032Speter 571538032Speter8.8.5/8.8.5 1997/01/21 571638032Speter SECURITY: Clear out group list during startup. Without this, sendmail 571738032Speter will continue to run with the group permissions of the caller, 571838032Speter even if RunAsUser is specified. 571938032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 572038032Speter to any known attack, but it's best to be conservative. 572138032Speter Suggested by Peter Wemm of DIALix. 572238032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 572338032Speter security implications. Patch from Alex Garthwaite of the 572438032Speter University of Pennsylvania. 572538032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 572638032Speter would truncate the address after "Full". Although the -f 572738032Speter syntax is incorrect (since it is in the envelope, it 572838032Speter shouldn't have comments and full names), the failure mode 572938032Speter was unnecessarily awful. 573038032Speter Fix a possible null pointer dereference when converting 8-bit data 573138032Speter to a 7-bit format. Problem noted by Jim Hutchins of 573238032Speter Sandia National Labs and David James of British Telecom. 573338032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 573438032Speter runs. Although this really shouldn't be used (F=9 is for 573538032Speter final delivery only, and using it on an SMTP mailer makes 573638032Speter it possible for a message to be converted from 8->7->8->7 573738032Speter bits several times), it shouldn't have failed with a syserr. 573838032Speter Problem noted by Eric Hagberg of Morgan Stanley. 573938032Speter _Really_ fix the multiple :maildrop code in the user database 574038032Speter module. Patch from Roy Mongiovi of Georgia Tech. 574138032Speter Let F lines in the configuration file actually read root-only 574238032Speter files if the configuration file is safe. Based on a 574338032Speter patch from Keith Reynolds of SCO. 574438032Speter ETRN followed by QUIT would hold the connection open until the queue 574538032Speter run completed. Problem noted by Truck Lewis of TDK 574638032Speter Semiconductor Corp. 574738032Speter It turns out that despite the documentation, the TCP wrappers library 574838032Speter does _not_ log rejected connections. Do the logging ourselves. 574938032Speter Problem noted by Fletcher Mattox of the University of Texas 575038032Speter at Austin. 575138032Speter If sendmail finds a qf file in its queue directory that is an unknown 575238032Speter version (e.g., when backing out to an old version), the 575338032Speter error is reported on every queue run. Change it to only 575438032Speter give the error once (and rename the qf => Qf). Patch from 575538032Speter William A. Gianopoulos of Raytheon Company. 575638032Speter Start a new session when doing background delivery; currently it 575738032Speter ignored signals but didn't start a new signal, that caused 575838032Speter some problems if a background process tried to send mail 575938032Speter under certain circumstances. Problem noted by Eric Hagberg 576038032Speter of Morgan Stanley; fix from Kari Hurtta. 576138032Speter Simplify test for skipping a queue run to just check if the current 576238032Speter load average is >= the queueing load average. Previously 576338032Speter the check factored in some other parameters that caused it 576438032Speter to essentially never skip the queue run. Patch from Bryan 576538032Speter Costales. 576638032Speter If the SMTP server is running in "nullserver" mode (that is, it is 576738032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 576838032Speter (25) commands; this helps prevent a bad guy from putting 576938032Speter you into a tight loop as a denial-of-service attack. Based 577038032Speter on an e-mail conversation with Brad Knowles of AOL. 577138032Speter Slow down when too many "light weight" commands have been issued; 577238032Speter this helps prevent a class of denial-of-service attacks. 577338032Speter The current values and defaults are: 577438032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 577538032Speter MAXHELOCOMMANDS 3 HELO, EHLO 577638032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 577738032Speter MAXETRNCOMMANDS 8 ETRN 577838032Speter These will probably be configurable in a future release. 577938032Speter On systems that have uid_t typedefed to be an unsigned short, programs 578038032Speter that had the F=S flag and no U= equate would be invoked with 578138032Speter the real uid set to 65535 rather than being left unchanged. 578238032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 578338032Speter by Steve Hubert of the University of Washington, Seattle. 578438032Speter Mail that was Quoted-Printable encoded and had a soft line break on 578538032Speter the last line (i.e., an incomplete continuation) had the last 578638032Speter line dropped. Since this appears to be illegal it isn't 578738032Speter clear what to do with it, but flushing the last line seems 578838032Speter to be a better "fail soft" approach. Based on a patch from 578938032Speter Eric Hagberg. 579038032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 579138032Speter bogus HELO command still causes the "Polite people say HELO 579238032Speter first" error message. Problem pointed out by Chris Thomas 579338032Speter of UCLA; patch from John Beck of SunSoft. 579438032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 579538032Speter in PrivacyOptions. The -q shouldn't turn this command off. 579638032Speter Problem noted by Murray Kucherawy of Pacific Bell Internet; 579738032Speter based on a patch from Gregory Neil Shapiro of WPI. 579838032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 579938032Speter in a DATA transaction to be sticky; these can occur because 580038032Speter a message is too large, and smaller messages should still go 580138032Speter through. Problem noted by Matt Dillon of Best Internet 580238032Speter Communications. 580338032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 580438032Speter had been successfully delivered to the envelope sender. 580538032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 580638032Speter Gregory Neil Shapiro of WPI. 580738032Speter Give better diagnostics on long alias lines. Based on code contributed 580838032Speter by Patrick Gosling of the University of Cambridge. 580938032Speter Increase the number of virtual interfaces that will be probed for 581038032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 581138032Speter PORTABILITY: 581238032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 581338032Speter Toshiaki Nomura of Fujitsu Limited. 581438032Speter SunOS with LDAP support: compile problems with struct timeval. 581538032Speter Patch from Nick Cuccia of TCSI Corporation. 581638032Speter SCO: from Keith Reynolds of SCO. 581738032Speter Solaris: kstat load average computation wasn't being used. 581838032Speter Fixes from Michael Ju.

Tweak it again. I'll omit the names 582838032Speter of the "contributors" (quantity two) in this one case. 582938032Speter As of now, NO MORE DISCUSSION about the syntax of the 583038032Speter Received: line. 583138032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 583238032Speter it never inserts that class into the output file. Fix it 583364562Sgshapiro so it will honor EXPOSED_USER but will _not_ include root 583438032Speter automatically in this class. Problem noted by Ronan KERYELL 583538032Speter of Centre de Recherche en Informatique de l'�cole Nationale 583638032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 583738032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 583838032Speter such as LUSER_RELAY. This change permits the following 583938032Speter syntaxes: ``local:'' will send to the same user on the 584038032Speter local machine (e.g., in a mailertable entry for "host", 584138032Speter ``local:'' will cause an address addressed to user@host to 584238032Speter go to user on the local machone). ``local:user'' will send 584338032Speter to the named user on the local machine. ``local:user@host'' 584438032Speter is equivalent to ``local:user'' (the host is ignored). In 584538032Speter all cases, the original user@host is passed in $@ (i.e., the 584638032Speter detail information). Inspired by a report from Michael Fuhr. 584738032Speter CONFIG: Strip quotes from the first word of an "error:" host 584838032Speter indication. This lets you set (for example) the LUSER_RELAY 584938032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 585038032Speter of the \" so that the resulting string is properly quoted. 585138032Speter Problem noted by Gregory Neil Shapiro of WPI. 585290792Sgshapiro OP.ME: documentation was inconsistent about whether sendmail did a 585338032Speter NOOP or a RSET to probe the connection (it does a RSET). 585438032Speter Inconsistency noted by Deeran Peethamparam. 585538032Speter OP.ME: insert additional blank pages so it will print properly on 585638032Speter a duplex printer. From Matthew Black of Cal State University, 585738032Speter Long Beach. 585838032Speter 585938032Speter8.8.4/8.8.4 1996/12/02 586038032Speter SECURITY: under some circumstances, an attacker could get additional 586138032Speter permissions by hard linking to files that were group 586238032Speter writable by the attacker. The solution is to disallow any 586338032Speter files that have hard links -- this will affect .forward, 586438032Speter :include:, and output files. Problem noted by Terry 586538032Speter Kyriacopoulos of Interlog Internet Services. As a 586638032Speter workaround, set UnsafeGroupWrites -- always a good idea. 586738032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 586838032Speter is, it is possible to do a denial-of-service attack on 586938032Speter MX hosts that rely on the use of the null MX list. There 587038032Speter is no danger if you have this option turned off (the default). 587138032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 587238032Speter unsafe. I know of no specific attack against this, although 587338032Speter a denial-of-service attack is probably possible, but in theory 587438032Speter you should not be able to safely tweak anything that affects 587538032Speter the permissions that are used when mail is delivered. 587638032Speter Purgestat could go into an infinite loop if one of the host status 587738032Speter directories somehow became empty. Problem noted by Roy 587864562Sgshapiro Mongiovi of Georgia Tech. 587938032Speter Processes got "lost" when counting children due to a race condition. 588038032Speter This caused "proc_list_probe: lost pid" messages to be logged. 588138032Speter Problem noted by several people. 588238032Speter On systems with System V SIGCLD child signal semantics (notably AIX 588338032Speter and HP-UX), mail transactions would print the message "451 588438032Speter SMTP-MAIL: lost child: No child processes". Problem noted 588538032Speter by several people. 588638032Speter Miscellaneous compiler warnings on picky compilers (or when setting 588738032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 588838032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 588938032Speter not be persistent between runs, since they are based on the 589038032Speter message rather than the host. Problem noted by Matt Dillon 589138032Speter of Best Internet Communications. 589238032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 589338032Speter of NCR (a.k.a., AT&T Global Information Solutions). 589438032Speter Avoid the possibility of having a child daemon run to completion 589538032Speter (including closing the SMTP socket) before the parent has 589638032Speter had a chance to close the socket; this can cause the parent 589738032Speter to hang for a long time waiting for the socket to drain. 589838032Speter Patch from Don Lewis of TDK Semiconductor. 589938032Speter If the fork() failed in a queue run, the queue runners would not be 590038032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 590138032Speter Some error conditions in ETRN could cause output without an SMTP 590238032Speter status code. Problem noted by Don Lewis. 590338032Speter Multiple :maildrop addresses in the user database didn't work properly. 590438032Speter Patch from Roy Mongiovi of Georgia Tech. 590538032Speter Add ".db" automatically onto any user database spec that does not 590638032Speter already have it; this is for consistency with makemap, the 590738032Speter K line, and the documentation. Inconsistency pointed out 590838032Speter by Roy Mongiovi. 590938032Speter Allow sendmail to be properly called in nohup mode. Patch from 591038032Speter Kyle Jones of UUNET. 591138032Speter Change ETRN to ignore but still update host status files; previously 591238032Speter it would ignore them and not save the updated status, which 591338032Speter caused stale information to be maintained. Based on a patch 591438032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 591538032Speter ETRN ignore the MinQueueAge option. 591638032Speter Patch long term host status to recover more gracefully from an empty 591738032Speter host status file condition. Patch from NAKAMURA Motonori 591838032Speter of Kyoto University. 591938032Speter Several patches to signal handling code to fix potential race 592038032Speter conditions from Don Lewis. 592138032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 592238032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 592338032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 592438032Speter compile flag; use NETINET instead. Solution based on a 592538032Speter patch from Bryan Costales. 592638032Speter PORTABILITY FIXES: 592738032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 592838032Speter /etc/security/passwd file when called as root. This 592938032Speter is very slow on some systems. To speed it up, use the 593038032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 593138032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 593238032Speter SCO 5.x: include -lprot in the Makefile.

By popular demand. 594938032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 595038032Speter from Jerome Berkman of U.C. Berkeley. 595138032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 595238032Speter to take a very long time. Problem noted by Yoshiro YONEYA 595338032Speter of NTT Software Corporation. 595438032Speter CONTRIB: add etrn.pl, contributed by John Beck. 595538032Speter NEW FILES: 595638032Speter contrib/etrn.pl 595738032Speter 595871345Sgshapiro8.8.3/8.8.3 1996/11/17 595971345Sgshapiro SECURITY: it was possible to get a root shell by lying to sendmail 596071345Sgshapiro about argv[0] and then sending it a signal. Problem noted 596138032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 596238032Speter best-of-security list. 596338032Speter Log sendmail binary version number in "Warning: .cf version level 596438032Speter (%d) exceeds program functionality (%d) message" -- this 596538032Speter should make it clearer to people that they are running 596638032Speter the wrong binary. 596738032Speter Fix a problem that occurs when you open an SMTP connection and then 596838032Speter do one or more ETRN commands followed by a MAIL command; at 596938032Speter the end of the DATA phase sendmail would incorrectly report 597038032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 597138032Speter noted by Eric Bishop of Virginia Tech. 597238032Speter When doing text-based host canonification (typically /etc/hosts 597338032Speter lookup), a null host name would match any /etc/hosts entry 597438032Speter with space at the end of the line. Problem noted by Steve 597538032Speter Hubert of the University of Washington, Seattle. 597638032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 597738032Speter Problem reported by Tom Smith of Digital Equipment Corp. 597838032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 597938032Speter size PACKETSZ (512) is not sufficient for some nameserver 598038032Speter answers containing very many resource records. The resolver 598138032Speter may also switch to TCP and retry if it detects UDP packet 598238032Speter overflow. Also, allow for the fact that the resolver 598338032Speter routines res_query and res_search return the size of the 598438032Speter *un*truncated answer in case the supplied answer buffer it 598538032Speter not big enough to accommodate the entire answer. Patch from 598638032Speter Eric Wassenaar. 598738032Speter Improvements to MaxDaemonChildren code. If you think you have too 598838032Speter many children, probe the ones you have to verify that they 598938032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 599038032Speter Also, do this probe before growing the vector of children 599138032Speter pids; this previously caused the vector to grow indefinitely 599238032Speter due to a race condition. Problem reported by Kyle Jones of 599338032Speter UUNET. 599438032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 599538032Speter O_EXLOCK to zero; this fools the map compilation code into 599638032Speter thinking that it can avoid race conditions by locking on open. 599738032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 599838032Speter Leif Erlingsson of Data Lege. 599938032Speter Always call res_init() on startup (if compiled in, of course) to 600038032Speter allow the sendmail.cf file to tweak resolver flags; without 600138032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 600238032Speter Andrew Sun of Merrill Lynch. 600338032Speter Improvements to host status printing code. Suggested by Steve Hubert 600438032Speter of the University of Washington, Seattle. 600538032Speter Change MinQueueAge option processing to do the check for the job age 600638032Speter when reading the queue file, rather than at the end; this 600738032Speter avoids parsing the addresses, which can do DNS lookups. 600838032Speter Problem noted by John Beck of InReference, Inc. 600938032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 601038032Speter properly escaped. Problem noted by Peter Nilsson of the 601138032Speter University of Linkoping. 601238032Speter In some cases, sendmail would retain root permissions during queue 601338032Speter runs even if RunAsUser was set. Problem noted by Mark 601438032Speter Thomas of Mark G. Thomas Consulting. 601538032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 601638032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 601738032Speter the envelope, and the receiving SMTP server speaks DSN, then 601838032Speter the DSN would be both generated locally and propagated to the 601938032Speter other end. 602038032Speter The U= mailer field didn't correctly extract the group id if the 602138032Speter user id was numeric. Problem noted by Kenneth Herron of 602264562Sgshapiro MCI Telecommunications Communications. 602338032Speter If a message exceeded the fixed maximum size on input, the body of 602438032Speter the message was included in the bounce. Note that this did 602538032Speter not occur if it exceeded the maximum _output_ size. Problem 602638032Speter reported by Kyle Jones of UUNET. 602738032Speter PORTABILITY FIXES: 602838032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 602938032Speter AIX4 defines to use seteuid(2) instead, which 603038032Speter works on 4.1 as well as 4.2. Problem noted by 603138032Speter H�kan Lindholm of interAF, Sweden. 603238032Speter AIX4: use tzname[] vector to determine time zone name. 603338032Speter Patch from NAKAMURA Motonori of Kyoto University. 603438032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 603538032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 603638032Speter Solaris: kstat(3k) support for retrieving the load average. 603738032Speter This adds the LA_KSTAT definition for LA_TYPE. 603838032Speter The outline of the implementation was contributed 603938032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 604038032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 604138032Speter declaration of struct rusage at the top of conf.h; 604238032Speter change it to only be included if you are using gcc, 604338032Speter which is apparently the only compiler that requires 604438032Speter it in the first place. Problem noted by Jeff 604538032Speter Earickson of Colby College. 604638032Speter IRIX: don't default to using gcc. IRIX is a civilized 604738032Speter operating system that comes with a decent compiler 604838032Speter by default. Problem noted by Barry Bouwsma and 604938032Speter Kari Hurtta. 605038032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 605138032Speter consistency with other local mailers. Inconsistency 605238032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 605338032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 605438032Speter overhead) as part of the bestmx_is_local feature, the 605538032Speter domain part was dropped from the name. Patch from Steve 605638032Speter Hubert of the University of Washington, Seattle. 605738032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 605838032Speter end up being translated to the null host name, which would 605938032Speter return any entry in /etc/hosts that had a space at the end 606038032Speter of the line. Problem noted by Steve Hubert of the 606138032Speter University of Washington, Seattle. 606238032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 606338032Speter Polytechnic Institute. 606438032Speter MAKEMAP: tweak hash and btree parameters for better performance. 606538032Speter Patch from Matt Dillon of Best Internet Communications. 606638032Speter NEW FILES: 606738032Speter src/Makefiles/Makefile.Linux.ppc 606838032Speter cf/ostype/aix4.m4 606938032Speter cf/ostype/mklinux.m4 607038032Speter 607138032Speter8.8.2/8.8.2 1996/10/18 607238032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 607338032Speter changed the code but didn't fix the problem. 607438032Speter PORTABILITY FIXES: 607538032Speter Solaris: Don't use the system getusershell(3); it can 607638032Speter apparently corrupt the heap in some circumstances. 607738032Speter Problem found by Ken Pizzini of Spry, Inc. 607838032Speter OP.ME: document several mailer flags that were accidentally omitted 607938032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 608038032Speter CONFIG: no changes. 608138032Speter 608238032Speter8.8.1/8.8.1 1996/10/17 608338032Speter SECURITY: unset all environment variables that the resolver will 608438032Speter examine during queue runs and daemon mode. Problem noted 608538032Speter by Dan Bernstein of the University of Illinois at Chicago. 608638032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 608738032Speter message could overflow a buffer if it was converted back 608838032Speter to 8 bits. This caused core dumps and has the potential 608938032Speter for a remote attack. Problem first noted by Gregory Shapiro 609038032Speter of WPI. 609138032Speter Avoid duplicate deliveries of error messages on systems that don't 609238032Speter have flock(2) support. Patch from Motonori Nakamura of 609338032Speter Kyoto University. 609438032Speter Ignore null FallBackMX (V) options. If this option is null (as 609538032Speter opposed to undefined) it can cause "null signature" syserrs 609638032Speter on illegal host names. 609738032Speter If a Base64 encoded text/plain message has no trailing newline in 609838032Speter the encoded text, conversion back to 8 bits will drop the 609938032Speter final line. Problem noted by Pierre David. 610038032Speter If running with a RunAsUser, sendmail would give bogus "cannot 610138032Speter setuid" (or seteuid, or setreuid) messages on some systems. 610238032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 610338032Speter Always print error messages in -bv mode -- previously, -bv would 610438032Speter be absolutely silent on errors if the error mode was sent 610538032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 610638032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 610738032Speter term host status. This is necessary because it is common 610838032Speter to do this when you know a host has just come back up. 610938032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 611038032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 611138032Speter University of Leicester. 611238032Speter If a service (such as NIS) is specified as the last entry in the 611338032Speter service switch, but that service is not compiled in, sendmail 611438032Speter would return a temporary failure when an entry was not found 611538032Speter in the map. This caused the message to be queued instead of 611638032Speter bouncing immediately. Problem noted by Harry Edmon of the 611738032Speter University of Washington. 611838032Speter PORTABILITY FIXES: 611938032Speter Solaris 2.3 had compilation problems in conf.c. Several 612038032Speter people pointed this out. 612164562Sgshapiro NetBSD from Charles Hannum of MIT. 612238032Speter AIX4 improvements based on info from Steve Bauer of South 612338032Speter Dakota School of Mines & Technology. 612438032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 612538032Speter Patch from Gil Kloepfer Jr. 612638032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 612738032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 612838032Speter were also in $=w. Problem noted by Zoltan Basti of 612938032Speter Softec. 613038032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 613138032Speter on a patch from Eric Hagberg of Morgan Stanley. 613238032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 613338032Speter of Stanford via Robert La Ferla. 613438032Speter 613538032Speter8.8.0/8.8.0 1996/09/26 613638032Speter Under some circumstances, Bcc: headers would not be properly 613738032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 613838032Speter Log a warning if the sendmail daemon is invoked without a full 613938032Speter pathname, which prevents "kill -1" from working. I was 614038032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 614138032Speter Fix small buffer overflow. Since the data in this buffer was not 614238032Speter read externally, there was no security problem (and in fact 614338032Speter probably wouldn't really overflow on most compilers). Pointed 614438032Speter out by KIZU takashi of Osaka University. 614538032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 614638032Speter if a FallbackMXHost was specified in the configuration file 614738032Speter -- all mail would be sent to the fallback even if the original 614838032Speter host was accessible. Pointed out by Munenari Hirayama of 614938032Speter NSC (Japan). 615038032Speter A message that didn't terminate with a newline would (sometimes) not 615138032Speter have the trailing "." added properly in the SMTP dialogue, 615238032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 615338032Speter The DaemonPortOptions suboption to bind to a particular address was 615438032Speter incorrect and nonfunctional due to a misunderstanding of the 615538032Speter semantics of binding on a passive socket. Patch from 615638032Speter NIIBE Yutaka of Mitsubishi Research Institute. 615738032Speter Increase the number of MX hosts for a single name to 100 to better 615838032Speter handle the truly huge service providers such as AOL, which 615938032Speter has 13 at the moment (and climbing). In order to avoid 616038032Speter trashing memory, the buffer for all names has only been 616138032Speter slightly increased in size, to 12.8K from 10.2K -- this means 616238032Speter that if a single name had 100 MX records, the average size 616338032Speter of those records could not exceed 128 bytes. Requested by 616438032Speter Brad Knowles of America On Line. 616538032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 616638032Speter Urged by Dan Bernstein of U.C. Berkeley. 616738032Speter Print q_statdate and q_specificity in address structure debugging 616838032Speter printout. 616938032Speter Expand MCI structure flag bits for debugging output. 617038032Speter Support IPv6-style domain literals, which can have colons between 617138032Speter square braces. 617238032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 617338032Speter this is an attempt to track down a bug that one person seems 617438032Speter to be having (it may be a Solaris bug!). 617538032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 617638032Speter this caused the NOTIFY info to sometimes be lost. Problem 617738032Speter pointed out by Claus Assmann of the 617838032Speter Christian-Albrechts-University of Kiel. 617938032Speter The statistics gathered in the sendmail.st file were too high; in 618038032Speter some cases failures (e.g., user unknown or temporary failure) 618138032Speter would count as a delivery as far as the statistics were 618238032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 618338032Speter Systems that don't have flock() would not send split envelopes in 618438032Speter the initial run. Problem pointed out by Leonard Zubkoff of 618538032Speter Dandelion Digital. 618638032Speter Move buffer overflow checking -- these primarily involve distrusting 618738032Speter results that may come from NIS and DNS. 618838032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 618938032Speter include <paths.h> and hence had the wrong pathnames for a few 619038032Speter things like /var/tmp. Reported by Matthew Green. 619138032Speter Conditions were reversed for the Priority: header, resulting in all 619238032Speter values being interpreted as non-urgent except for non-urgent, 619338032Speter which was interpreted as normal. Patch from Bryan Costales. 619438032Speter The -o (optional) flag was being ignored on hash and btree maps 619538032Speter since 8.7.2. Fix from Bryan Costales. 619638032Speter Content-Types listed in class "q" will always be encoded as 619738032Speter Quoted-Printable (or more accurately, will never be encoded 619838032Speter as base64). The class can have primary types (e.g., "text") 619938032Speter or full types (e.g., "text/plain"). Based on a suggestion by 620038032Speter Marius Olafsson of the University of Iceland. 620138032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 620238032Speter dialogue) so it can be passed to programs in mailers. 620338032Speter Define ${bodytype} to be the body type (from the -B flag or the 620438032Speter BODY= ESMTP parameter) so it can be passed to programs in 620538032Speter mailers. 620638032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 620738032Speter flag is set in the mailer descriptor. Suggested by John 620838032Speter Myers of CMU. 620938032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 621038032Speter The command takes a host name; data for that host is 621138032Speter immediately (and asynchronously) flushed. Because this shares 621238032Speter the -qR implementation, other hosts may be attempted, but 621338032Speter there should be no security implications. Implementation 621438032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 621538032Speter Add three new command line flags to pass in DSN parameters: -V envid 621638032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 621738032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 621838032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 621938032Speter that the -N flag applies to all recipients; there is no way 622038032Speter to specify per-address notifications on the command line, 622138032Speter nor is there an equivalent for the ORCPT= per-address 622238032Speter parameter. 622338032Speter Restore LogLevel option to be safe (it can only be increased); 622438032Speter apparently I went into paranoid mode between 8.6 and 8.7 622538032Speter and made it unsafe. Pointed out by Dabe Murphy of the 622638032Speter University of Maryland. 622738032Speter New logging on log level 15: all SMTP traffic. Patches from 622838032Speter Andrew Gross of San Diego Supercomputer Center. 622938032Speter NetInfo property value searching code wasn't stopping when it found 623038032Speter a match. This was causing the wrong values to be found (and 623138032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 623238032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 623338032Speter out by Bill Wisner of Electronics for Imaging that you can't 623464562Sgshapiro use the bracket address form for the MAIL_HUB macro, since 623538032Speter that causes the brackets to remain in the envelope recipient 623638032Speter address used for delivery. The simple fix (stripping off the 623738032Speter brackets in the config file) breaks the use of IP literal 623838032Speter addresses. This flag will solve that problem. 623938032Speter Add MustQuoteChars option. This is a list of characters that must 624038032Speter be quoted if they are found in the phrase part of an address 624138032Speter (that is, the full name part). The characters @,;:\()[] are 624238032Speter always in this list and cannot be removed. The default is 624338032Speter this list plus . and ' to match RFC 822. 624438032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 624564562Sgshapiro that do not include a host name for back compatibility with 624638032Speter some stupid SMTP clients. Setting this violates RFC 1123 624738032Speter section 5.2.5. 624838032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 624938032Speter rejecting connections if it has more than this many 625038032Speter outstanding children accepting mail. Note that you may 625138032Speter see more processes than this because of outgoing mail; this 625238032Speter is for incoming connections only. 625338032Speter Add ConnectionRateThrottle option. If set to a positive value, the 625438032Speter number of incoming SMTP connections that will be permitted 625538032Speter in a single second is limited to this number. Connections are 625638032Speter not refused during this time, just deferred. The intent is to 625738032Speter flatten out demand so that load average limiting can kick in. 625838032Speter It is less radical than MaxDaemonChildren, which will stop 625938032Speter accepting connections even if all the connections are idle 626038032Speter (e.g., due to connection caching). 626138032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 626238032Speter specifies how long cached information about the state of a 626338032Speter host will be kept before they are considered stale and the 626438032Speter host is retried. If you are using persistent host status 626538032Speter (i.e., the HostStatusDirectory option is set) this will apply 626638032Speter between runs; otherwise, it applies only within a single queue 626738032Speter run and hence is useful only for hosts that have large queues 626838032Speter that take a very long time to run. 626938032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 627038032Speter into being a single line even if they had newlines in them 627138032Speter when read. This is to get around a botch in Lotus Notes. 627238032Speter Text class maps were totally broken -- if you ever retrieved the last 627338032Speter item in a table it would be truncated. Problem noted by 627438032Speter Gregory Neil Shapiro of WPI. 627538032Speter Extend the lines printed by the mailq command (== the -bp flag) when 627638032Speter -v is given to 120 characters; this allows more information 627738032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 627838032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 627938032Speter this was treated as end-of-input. Problem noted by Bryan 628038032Speter Costales. 628138032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 628238032Speter to the queue file. Fix from John Hughes of Atlantic 628338032Speter Technologies, Inc. 628438032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 628538032Speter if this happens in a queue run it can cause nasty delays. 628638032Speter Problem noted by Mark Horton of AT&T. 628738032Speter If userdb entries pointed to userdb entries, and there were multiple 628838032Speter values for a given key, the database cursor would get 628938032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 629038032Speter of Georgia Tech. Fixed by reading all the values and creating 629138032Speter a comma-separated list; thus, the -v output will be somewhat 629238032Speter different for this case. 629338032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 629438032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 629538032Speter of Stanford University. 629638032Speter When envelopes were split due to aliases with owner- aliases, and 629738032Speter there was some error on one of the lists, more than one of 629864562Sgshapiro the owners would get the message. Problem pointed out by 629938032Speter Roy Mongiovi of Georgia Tech. 630038032Speter Detect excessive recursion in macro expansions, e.g., $X defined 630138032Speter in terms of $Y which is defined in terms of $X. Problem 630238032Speter noted by Bryan Costales; patch from Eric Wassenaar. 630338032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 630438032Speter some cases get trashed causing bogus From_ lines. Fix from 630538032Speter Kyle Jones of UUNET. 630638032Speter When doing load average initialization, if the nlist call for avenrun 630738032Speter failed, the second and subsequent lookups wouldn't notice 630838032Speter that fact causing bogus load averages to be returned. Noted 630938032Speter by Casper Dik of Sun Holland. 631038032Speter Fix problem with incompatibility with some versions of inet_aton that 631138032Speter have changed the return value to unsigned, so a check for an 631238032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 631338032Speter This could cause mail to addresses such as [foo.com] to bounce 631438032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 631538032Speter Pasteur Institute. 631638032Speter DSNs were inconsistent if a failure occurred during the DATA phase 631738032Speter rather than the RCPT phase: the Action: would be correct, but 631838032Speter the detailed status information would be wrong. Problem noted 631938032Speter by Bob Snyder of General Electric Company. 632038032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 632138032Speter that this is the initial MUA->MTA submission. The flag current 632238032Speter does nothing, but in future releases (when MUAs start using 632338032Speter these flags) it will probably turn on things like DNS 632438032Speter canonification. 632538032Speter Default end-of-line string (E= specification on mailer [M] lines) 632638032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 632738032Speter mailers. 632838032Speter Change the internal definition for the *file* and *include* mailers 632938032Speter to have $u in the argument vectors so that they aren't 633038032Speter misinterpreted as SMTP mailers and thus use \r\n line 633138032Speter termination. This will affect anyone who has redefined 633238032Speter either of these in their configuration file. 633338032Speter Don't assume that IDENT servers close the connection after a query; 633438032Speter responses can be newline terminated. From Terry Kennedy of 633538032Speter St. Peter's College. 633638032Speter Avoid core dumps on erroneous configuration files that have 633738032Speter $#mailer with nothing following. From Bryan Costales. 633838032Speter Avoid null pointer dereference with high debug values in unlockqueue. 633938032Speter Fix from Randy Martin of Clemson University. 634038032Speter Fix possible buffer overrun when expanding very large macros. Fix 634138032Speter from Kyle Jones of UUNET. 634238032Speter After 25 EXPN or VRFY commands, start pausing for a second before 634338032Speter processing each one. This avoids a certain form of denial 634438032Speter of service attack. Potential attack pointed out by Bryan 634538032Speter Costales. 634638032Speter Allow new named (not numbered!) config file rules to do validity 634738032Speter checking on SMTP arguments: check_mail for MAIL commands and 634838032Speter check_rcpt for RCPT commands. These rulesets can do anything 634938032Speter they want; their result is ignored unless they resolve to the 635038032Speter $#error mailer, in which case the indicated message is printed 635138032Speter and the command is rejected. Similarly, the check_compat 635238032Speter ruleset is called before delivery with "from_addr $| to_addr" 635338032Speter (the $| is a meta-symbol used to separate the two addresses); 635438032Speter it can give a "this sender can't send to this recipient" 635538032Speter notification. Note that this patch allows $| to stand alone 635638032Speter in rulesets. 635738032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 635838032Speter that have the name, IP address, and port number (respectively) 635938032Speter of the SMTP client (that is, the entity at the other end of 636038032Speter the connection. These can be used in (e.g.) check_rcpt to 636138032Speter verify that someone isn't trying to relay mail through your 636238032Speter host inappropriately. Be sure to use the deferred evaluation 636338032Speter form, for example $&{client_name}, to avoid having these bound 636438032Speter when sendmail reads the configuration file. 636538032Speter Add new config file rule check_relay to check the incoming connection 636638032Speter information. Like check_compat, it is passed the host name 636738032Speter and host address separated by $| and can reject connections 636838032Speter on that basis. 636938032Speter Allow IDA-style recursive function calls. Code contributed by Mark 637038032Speter Lovell and Paul Vixie. 637138032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 637238032Speter a virtual UUCP address using either a domain address or the $k 637338032Speter macro. Based on code contributed by Mark Lovell and Paul 637438032Speter Vixie. 637538032Speter Add Stanford LDAP map. Requires special libraries that are not 637638032Speter included with sendmail. Contributed by Booker C. Bense 637738032Speter <bbense@networking.stanford.edu>; contact him for support. 637838032Speter See also the src/READ_ME file. 637938032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 638038032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 638138032Speter only for debugging deep bits of code where it is important to 638238032Speter distinguish between the single-character metasymbol $+ and the 638338032Speter two characters $, +. 638438032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 638538032Speter debug_dumpstate. 638638032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 638738032Speter files that are group writable are considered "unsafe" -- that 638838032Speter is, programs and files referenced from such files are not 638938032Speter valid recipients. 639038032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 639138032Speter name that was not in DNS or was a domain-literal. Problem 639238032Speter noted by Tom May. 639338032Speter Change the introduction to error messages to more clearly delineate 639438032Speter permanent from temporary failures; if both existed in a 639538032Speter single message it could be confusing. Suggested by John 639638032Speter Beck of InReference, Inc. 639738032Speter The IngoreDot (i) option didn't work for lines that were terminated 639838032Speter with CRLF. Problem noted by Ted Stockwell of Secure 639938032Speter Computing Corporation. 640038032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 640138032Speter message headers. Problem reported by Matt Dillon of Best 640238032Speter Internet Communications. 640338032Speter Check for bogus characters in the 0200-0237 range; since these are 640438032Speter used internally, very strange errors can occur if those 640538032Speter characters appear in headers. Problem noted by Anders Gertz 640638032Speter of Lysator. 640738032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 640838032Speter recipient mailer has the F=9 flag set, and only works on 640938032Speter text/plain body types. Code contributed by Marius Olafsson 641038032Speter of the University of Iceland. 641138032Speter Special case "postmaster" name so that it is always treated as lower 641238032Speter case in alias files regardless of configuration settings; 641338032Speter this prevents some potential problems where "Postmaster" or 641438032Speter "POSTMASTER" might not match "postmaster". In most cases 641538032Speter this change is a no-op. 641638032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 641738032Speter Costales. 641838032Speter The -a map flag was ignored for dequote maps. Problem noted by 641938032Speter Bryan Costales. 642038032Speter Fix core dump when a lookup of a class "prog" map returns no 642138032Speter response. Patch from Bryan Costales. 642238032Speter Log instances where sendmail is deferring or rejecting connections 642338032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 642438032Speter Include port number in process title for network daemons. Suggested 642538032Speter by Kyle Jones of UUNET. 642638032Speter Send ``double bounces'' (errors that occur when sending an error 642738032Speter message) to the address indicated in the DoubleBounceAddress 642838032Speter option (default: postmaster). Previously they were always 642938032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 643038032Speter Add new mode, -bD, that acts like -bd in all respects except that 643138032Speter it runs in foreground. This is useful for using with a 643238032Speter wrapper that "watches" system services. Suggested by Kyle 643338032Speter Jones of UUNET. 643438032Speter Fix botch in spacing around (parenthesized) comments in addresses 643538032Speter when the comment comes before the address. Patch from 643638032Speter Motonori Nakamura of Kyoto University. 643738032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 643838032Speter that are being bounced to postmaster, rather than "Returned 643938032Speter mail". This permits the person who is postmaster more 644038032Speter easily determine what messages are to their role as 644138032Speter postmaster versus bounces to mail they actually sent. Based 644238032Speter on a suggestion by Motonori Nakamura. 644338032Speter Add new value "time" for QueueSortOrder option; this causes the queue 644438032Speter to be sorted strictly by the time of submission. Note that 644538032Speter this can cause very bad behavior over slow lines (because 644638032Speter large jobs will tend to delay small jobs) and on nodes with 644738032Speter heavy traffic (because old things in the queue for hosts that 644838032Speter are down delay processing of new jobs). Also, this does not 644938032Speter guarantee that jobs will be delivered in submission order 645038032Speter unless you also set DeliveryMode=queue. In general, it should 645138032Speter probably only be used on the command line, and only in 645238032Speter conjunction with -qRhost.domain. In fact, there are very few 645338032Speter cases where it should be used at all. Based on an 645438032Speter implementation by Motonori Nakamura. 645538032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 645638032Speter the same manner as other rulesets. Previously a temporary 645738032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 645838032Speter of Stanford University. 645938032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 646038032Speter 5yz (permanent failure) code. The next MX host will still be 646138032Speter tried if the connection cannot be opened in the first place 646238032Speter or if the MAIL command returns a 4yz (temporary failure) code. 646338032Speter (It's hard to know what to do here, since neither RFC 974 nor 646438032Speter RFC 1123 specify when to proceed to the next MX host.) 646538032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 646638032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 646738032Speter This causes map lookups that get a temporary failure (e.g., 646838032Speter name server failure) to _not_ defer the delivery of the 646938032Speter message. This should only be used if your configuration file 647038032Speter is prepared to do something sensible in this case. Based on 647138032Speter an idea by Gregory Shapiro of WPI. 647238032Speter Fix problem finding network interface addresses. Patch from 647338032Speter Motonori Nakamura. 647438032Speter Don't reject qf entries that are not owned by your effective uid if 647538032Speter you are not running set-user-ID; this makes management of 647638032Speter certain kinds of firewall setups difficult. Patch 647738032Speter suggested by Eamonn Coleman of Qualcomm. 647838032Speter Add persistent host status. This keeps the information normally 647938032Speter maintained within a single queue run in disk files that are 648038032Speter shared between sendmail instances. The HostStatusDirectory 648138032Speter is the directory in which the information is maintained. If 648238032Speter not set, persistent host status is turned off. If not a full 648338032Speter pathname, it is relative to the queue directory. A common 648438032Speter value is ".hoststat". 648538032Speter There are also two new operation modes: 648638032Speter * -bh prints the status of hosts that have had recent 648738032Speter connections. 648838032Speter * -bH purges the host statuses. No attempt is made to save 648938032Speter recent status information. 649038032Speter This feature was originally written by Paul Vixie of Vixie 649138032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 649238032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 649338032Speter with my insistence that things fit cleanly into the V8 649438032Speter framework is gratefully appreciated. 649538032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 649638032Speter operate). Avoids letting two sendmails on the local machine 649738032Speter open connections to the same remote host at the same time. 649838032Speter This reduces load on the other machine, but can cause mail to 649938032Speter be delayed (for example, if one sendmail is delivering a huge 650038032Speter message, other sendmails won't be able to send even small 650138032Speter messages). Also, it requires another file descriptor (for the 650238032Speter lock file) per connection, so you may have to reduce 650338032Speter ConnectionCacheSize to avoid running out of per-process 650438032Speter file descriptors. Based on the persistent host status code 650538032Speter contributed by Paul Vixie and Mark Lovell. 650638032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 650738032Speter SafeFileEnvironment option is set. Problem noted by Bryan 650838032Speter Costales. 650938032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 651038032Speter file. Problem noted by Bryan Costales. 651138032Speter If a job was aborted using the interrupt signal (e.g., control-C from 651238032Speter the keyboard), on some occasions an empty df file would be 651338032Speter left around; these would collect in the queue directory. 651438032Speter Problem noted by Bryan Costales. 651538032Speter Change the makesendmail script to enhance the search for Makefiles 651638032Speter based on release number. For example, on SunOS 5.5.1, it will 651738032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 651838032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 651938032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 652038032Speter Webmasters. 652138032Speter When creating maps using "newaliases", always map the keys to lower 652238032Speter case when creating the map unless the -f flag is specified on 652338032Speter the map itself. Previously this was done based on the F=u 652438032Speter flag in the local mailer, which meant you could create aliases 652538032Speter that you could never access. Problem noted by Bob Wu of DEC. 652638032Speter When a job was read from the queue, the bits causing notification on 652738032Speter failure or delay were always set. This caused those 652838032Speter notifications to be sent even if NOTIFY=NEVER had been 652938032Speter specified. Problem noted by Steve Hubert of the University 653038032Speter of Washington, Seattle. 653138032Speter Add new configurable routine validate_connection (in conf.c). This 653238032Speter lets you decide if you are willing to accept traffic from 653338032Speter this host. If it returns FALSE, all SMTP commands will return 653438032Speter "550 Access denied". -DTCPWRAPPERS will include support for 653538032Speter TCP wrappers; you will need to add -lwrap to the link line. 653638032Speter (See src/READ_ME for details.) 653738032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 653838032Speter bounces. Some people seemed to think that this could be 653938032Speter confusing (even though it is true). Suggested by Motonori 654038032Speter Nakamura. 654138032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 654238032Speter user early in processing to avoid potential security problems. 654338032Speter However, this means that all .forward and :include: files must 654438032Speter be readable by that user, and all files to be written must be 654538032Speter writable by that user and all programs will be executed by that 654638032Speter user. It is also incompatible with the SafeFileEnvironment 654738032Speter option. In other words, it may not actually add much to 654838032Speter security. However, it should be useful on firewalls and other 654938032Speter places where users don't have accounts and the aliases file is 655038032Speter well constrained. 655138032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 655238032Speter only on the first attempt to delivery to an address. It could 655338032Speter be set to be lower than Timeout.connect on the principle that 655438032Speter the mail should go through quickly to responsive hosts; less 655538032Speter responsive hosts get to wait for the next queue run. 655638032Speter Fix a problem on Solaris that occasionally causes programs 655738032Speter (such as vacation) to hang with their standard input connected 655838032Speter to a UDP port. It also created some signal handling problems. 655938032Speter The problems turned out to be an interaction between vfork(2) 656038032Speter and some of the libraries, particularly NIS/NIS+. I am 656138032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 656238032Speter Change user class map to do the same matching that actual delivery 656338032Speter will do instead of just a /etc/passwd lookup. This adds 656438032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 656538032Speter The Timeout.* options are not safe -- they can be used to create a 656638032Speter denial-of-service attack. Problem noted by Christophe 656738032Speter Wolfhugel. 656838032Speter Don't send PostmasterCopy messages in the event of a "delayed" 656938032Speter notification. Suggested by Barry Bouwsma. 657038032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 657138032Speter option is set, since this disables VERB mode. Suggested 657238032Speter by John Hawkinson of MIT. 657338032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 657438032Speter by Motonori Nakamura of Kyoto University. 657538032Speter Only queue messages on transient .forward open failures if there 657638032Speter were no successful opens. The previous behavior caused it 657738032Speter to queue even if a "fall back" .forward was found.

Based on a patch from Randall 664080785Sgshapiro Winchester of the University of Maryland. 664138032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 664238032Speter Robert La Ferla of Hot Software. 664338032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 664438032Speter (where "code" is an exit status) on domains (previously 664538032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 664638032Speter Foundation. 664738032Speter CONFIG: hooks for IPv6-style domain literals. 664838032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 664938032Speter if it is undefined the AliasFile option is never set; this 665038032Speter should be transparent for most everyone. Suggested by John 665138032Speter Myers of CMU. 665238032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 665338032Speter domain listed in $=w is masqueraded. With it, only those 665438032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 665538032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 665638032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 665738032Speter hosts under those domains as well as the domain headers 665838032Speter themselves. For example, if a configuration had 665938032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 666064562Sgshapiro foo.com would be masqueraded; with it, *.foo.com would be 666138032Speter masqueraded as well. Based on an implementation by Richard 666238032Speter (Pug) Bainter of U. Texas. 666338032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 666438032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 666538032Speter Keys are user names; values are outgoing mail addresses. Yes, 666638032Speter this does overlap with the user database, and figuring out 666738032Speter just when to use which one may be tricky. Based on code 666838032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 666938032Speter from Per Hedeland of Ericsson. 667038032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 667138032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 667238032Speter Keys are either fully qualified addresses or just the host 667338032Speter part (with the @ sign). For example, a table containing: 667438032Speter info@foo.com foo-info 667538032Speter info@bar.com bar-info 667638032Speter @baz.org jane@elsewhere.net 667738032Speter would send all mail destined for info@foo.com to foo-info 667838032Speter (which is presumably an alias), mail addressed to info@bar.com 667938032Speter to bar-info, and anything addressed to anyone at baz.org will 668038032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 668138032Speter and baz.org must all be in $=w. Based on discussions with 668238032Speter a great many people. 668338032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 668438032Speter Suggested by Richard Bainter. 668538032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 668638032Speter "fax" mailer. 668738032Speter CONFIG: allow mailertable entries to resolve to local:user; this 668838032Speter passes the original user@host in to procmail-style local 668938032Speter mailers as the "detail" information to allow them to do 669038032Speter additional clever processing. From Joe Pruett of 669138032Speter Teleport Corporation. Delivery to the original user can 669238032Speter be done by specifying "local:" (with nothing after the colon). 669338032Speter CONFIG: allow any context that takes "mailer:domain" to also take 669438032Speter "mailer:user@domain" to force mailing to the given user; 669538032Speter "local:user" can also be used to do local delivery. This 669638032Speter applies on *_RELAY and in the mailertable entries. Based 669738032Speter on a suggestion by Ribert Kiessling of Easynet. 669838032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 669938032Speter limits the possible domains; this reduces the number of DNS 670038032Speter lookups required to support this feature. For example, 670138032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 670238032Speter to domains under my.site.com. Code contributed by Anthony 670338032Speter Thyssen <anthony@cit.gu.edu.au>. 670438032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 670538032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 670638032Speter of WPI. 670738032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 670838032Speter event you have to define local mailers. Suggested by 670938032Speter Gregory Shapiro of WPI. 671038032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 671138032Speter be misinterpreted as a list:...; syntax. Based on a patch by 671238032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 671338032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 671438032Speter remotely connected. The address host!user was being 671538032Speter converted to host!user@thishost instead of host!user@uurelay. 671638032Speter Problem noted by William Gianopoulos of Raytheon Company. 671738032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 671838032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 671938032Speter "User has moved"; the former wording was confusing if the 672038032Speter new address is still on the local host. Based on a suggestion 672138032Speter by Andreas Luik. 672238032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 672338032Speter However, the class is not pre-initialized to contain root. 672438032Speter Suggested by Gregory Neil Shapiro. 672538032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 672638032Speter Wolfhugel. 672738032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 672838032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 672938032Speter well: this produces a slightly different mailbox format (no 673038032Speter Content-Length: headers), file ownerships and modes are 673143730Speter different (not owned by group mail; mode 600 instead of 660), 673238032Speter and the local mailer flags will have to be tweaked (make them 673338032Speter match bsd4.4) in order to use this mailer. Patches from Paul 673438032Speter Hammann of the Missouri Research and Education Network. 673538032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 673638032Speter was a delivery error, such as if the ownership on the file 673738032Speter was wrong or the mode changed between the initial stat and 673838032Speter the open. Problem reported by William Colburn of the New 673943730Speter Mexico Institute of Mining and Technology. 674038032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 674138032Speter Costales. 674238032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 674338032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 674438032Speter honored.

This is not exploitable from off-site. 678138032Speter Workarounds include using a unique user for the DefaultUser 678238032Speter (old u & g options) and using smrsh as the local shell. 678338032Speter SECURITY: fix some buffer overruns; in at least one case this allows 678438032Speter a local user to get root. This is not known to be exploitable 678538032Speter from off-site.

They were not 682438032Speter properly repaired in 8.7.1. 682538032Speter Completely delete the Bcc: header if and only if there are other 682638032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 682738032Speter last being a historic botch, of course). If Bcc: is the 682838032Speter only recipient header in the message, its value is tossed, 682938032Speter but the header name is kept. The old behavior (always keep 683038032Speter the header name and toss the value) allowed primary recipients 683138032Speter to see that a Bcc: went to _someone_. 683238032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 683338032Speter sender to <address> using -f'' syslog messages. Suggested 683438032Speter by Kari Hurtta. 683538032Speter If a sequence or switch map lookup entry gets a tempfail but then 683638032Speter continues on to another map type, but the name is not found, 683738032Speter return a temporary failure from the sequence or switch map. 683838032Speter For example, if hosts search ``dns files'' and DNS fails 683938032Speter with a tempfail, the hosts map will go on and search files, 684038032Speter but if it fails the whole thing should be a tempfail, not 684138032Speter a permanent (host unknown) failure, even though that is the 684238032Speter failure in the hosts.files map. This error caused hard 684338032Speter bounces when it should have requeued. 684438032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 684538032Speter owned by bar mode 700 and inbox being set-user-ID bar stopped 684638032Speter working properly due to excessive paranoia. Pointed out by 684738032Speter John Hawkinson of Panix. 684838032Speter An SMTP RCPT command referencing a host that gave a nameserver 684938032Speter timeout would return a 451 command (8.6 accepted it and 685038032Speter queued it locally). Revert to the 8.6 behavior in order 685138032Speter to simplify queue management for clustered systems. Suggested 685238032Speter by Gregory Neil Shapiro of WPI. The same problem could break 685338032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 685438032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 685538032Speter Infobiogen. 685638032Speter Fix possible buffer overflow in munchstring(). This was not a security 685738032Speter problem because you couldn't specify any argument to this 685838032Speter without first giving up root privileges, but it is still a 685938032Speter good idea to avoid future problems. Problem noted by John 686038032Speter Hawkinson and Sam Hartman of MIT. 686138032Speter ``452 Out of disk space for temp file'' messages weren't being 686238032Speter printed. Fix from David Perlin of Nanosoft. 686338032Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 686438032Speter is not set, since this is required to get the actual DSNs 686538032Speter created. Problem pointed out by John Gardiner Myers of CMU. 686638032Speter Log permission problems that cause .forward and :include: files to 686738032Speter be untrusted or ignored on log level 12 and higher.

Pointed out by Mark Andrews of SGI and Jack Woolley 687338032Speter of Systems and Computer Technology Corporation. 687438032Speter If a message is sent to an address that fails, the error message that 687538032Speter is returned could show some extraneous "success" information 687638032Speter included even if the user did not request success notification, 687738032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 687838032Speter Config files that had no AliasFile definition were defaulting to 687938032Speter using /etc/aliases; this caused problems with nullclient 688038032Speter configurations.

Patch from Booker C. Bense of Stanford 690938032Speter University. 691038032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 691138032Speter the parent should do this. Fix from Brian Coan of the 691238032Speter Association for Progressive Communications. 691338032Speter If MinQueueAge was set and a message was considered but not run 691438032Speter during a queue run and the Timeout.queuereturn interval was 691538032Speter reached, a "timed out" error message would be returned that 691638032Speter didn't include the failed address (and claimed to be a warning 691738032Speter even though it was fatal). The fix is to not return such 691838032Speter messages until they are actually tried, i.e., in the next 691938032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 692038032Speter SINTEF RUNIT, Oslo. 692138032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 692238032Speter that have the hes_getmailhost() routine.

Bug 696938032Speter pointed out by John Hawkinson of MIT. 697038032Speter Fix strange case of an executable called by a program map that 697138032Speter returns a value but also a non-zero exit status; this 697238032Speter would give contradictory results in the higher level; in 697338032Speter particular, the default clause in the map lookup would be 697438032Speter ignored. Change to ignore the value if the program returns 697538032Speter non-zero exit status. From Tom Moore of AT&T GIS. 697638032Speter Shorten parameters passed to syslog() in some contexts to avoid a 697738032Speter bug in many vendors' implementations of that routine. Although 697838032Speter this isn't really a bug in sendmail per se, and my solution 697938032Speter has to assume that syslog() has at least a 1K buffer size 698038032Speter internally (I know some vendors have shortened this 698138032Speter dramatically -- they're on their own), sendmail is a popular 698238032Speter target. Also, limit the size of %s arguments in sprintf. 698338032Speter These both have possible security implications. Solutions 698464562Sgshapiro suggested by Casper Dik of Sun's Network Security Group 698538032Speter (Holland), Mark Seiden, and others. 698638032Speter Fix a problem that might cause a non-standard -B (body type) 698738032Speter parameter to be passed to the next server with undefined 698838032Speter results. This could have security implications. 698938032Speter If a filesystem was at > 100% utilization, the freediskspace() 699038032Speter routine incorrectly returned an error rather than zero. 699138032Speter Problem noted by G. Paul Ziemba of Alantec. 699243730Speter Change MX sort order so that local hostnames (those in $=w) always 699338032Speter sort first within a given preference. This forces the bestmx 699438032Speter map to always return the local host first, if it is included 699538032Speter in the list of highest priority MX records. From K. Robert 699638032Speter Elz. 699738032Speter Avoid some possible null pointer dereferences. Fixes from Randy 699838032Speter Martin <WOLF@CLEMSON.EDU> 699938032Speter When sendmail starts up on systems that have no fully qualified 700038032Speter domain name (FQDN) anywhere in the first matching host map 700138032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 700238032Speter sendmail would sleep to try to find a FQDN, which it really 700338032Speter really needs. This has been changed to fall through to the 700438032Speter next map type if it can't find a FQDN -- i.e., if the hosts 700538032Speter file doesn't have a FQDN, it will try dns even though the 700638032Speter short name was found in /etc/hosts. This is probably a crock, 700738032Speter but many people have hosts files without FQDNs. Remember: 700890792Sgshapiro domain names are your friends. 700938032Speter Log a high-priority message if you can't find your FQDN during startup. 701038032Speter Suggested by Simon Barnes of Schlumberger Limited. 701138032Speter When using Hesiod, initialize it early to improve error reporting. 701238032Speter Patch from Don Lewis of Silicon Systems, Inc. 701343730Speter Apparently at least some versions of Linux have a 90 !minute!

Based on code contributed by J.R. Oldroyd 701738032Speter of TerraNet. 701838032Speter Under some circumstances, a failed message would not be properly 701938032Speter removed from the queue, causing tons of bogus error messages. 702038032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 702138032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 702238032Speter of WPI. 702338032Speter PORTABILITY FIXES: 702438032Speter On IRIX 5.x, there was an inconsistency in the setting 702538032Speter of sendmail.st location.

This was used "safely" in the sense 705938032Speter that it only did a stat, but it would have set the 706038032Speter map modification time improperly. Problem pointed out 706138032Speter by Roy Mongiovi of Georgia Tech. 706238032Speter Clean up the Subject: line on warning messages and return 706338032Speter receipts so that they don't say "Returned mail:"; this 706438032Speter can be confusing. 706538032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 706638032Speter useful enough to make it worthwhile printing on "-d". 706738032Speter Avoid logging alias statistics every time you read the alias 706838032Speter file on systems with no database method compiled in. 706938032Speter If you have a name with a trailing dot, and you try looking it 707038032Speter up using gethostbyname without the dot (for /etc/hosts 707138032Speter compatibility), be sure to turn off RES_DEFNAMES and 707238032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 707338032Speter Problem noted by Charles Amos of the University of 707438032Speter Maryland. 707538032Speter Don't do timeouts in collect if you are not running SMTP. 707638032Speter There is nothing that says you can't have a long 707738032Speter running program piped into sendmail (possibly via 707838032Speter /bin/mail, which just execs sendmail). Problem reported 707938032Speter by Don "Truck" Lewis of Silicon Systems. 708038032Speter Try gethostbyname() even if the DNS lookup fails iff option I 708138032Speter is not set. This allows you to have hosts listed in 708238032Speter NIS or /etc/hosts that are not known to DNS. It's normally 708338032Speter a bad idea, but can be useful on firewall machines. This 708438032Speter should really be broken out on a separate flag, I suppose. 708538032Speter Avoid compile warnings against BIND 4.9.3, which uses function 708638032Speter prototypes.

From Kyle Jones of UUNET. 709138032Speter SECURITY: avoid denial-of-service attacks possible by destroying 709238032Speter the alias database file by setting resource limits low. 709338032Speter This involves adding two new compile-time options: 709438032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 709538032Speter available) and HASULIMIT (indicating that ulimit(2) support 709638032Speter is available -- the Release 3 form is used). The former 709738032Speter is assumed on BSD-based systems, the latter on System 709838032Speter V-based systems. Attack noted by Phil Brandenberger of 709938032Speter Swarthmore University. 710038032Speter New syntaxes in test (-bt) mode: 710138032Speter ``.Dmvalue'' will define macro "m" to "value". 710238032Speter ``.Ccvalue'' will add "value" to class "c". 710338032Speter ``=Sruleset'' will dump the contents of the indicated 710438032Speter ruleset. 710538032Speter ``=M'' will display the known mailers. 710638032Speter ``-ddebug-spec'' is equivalent to the command-line 710738032Speter -d debug flag. 710838032Speter ``$m'' will print the value of macro $m. 710938032Speter ``$=c'' will print the contents of class $=c. 711038032Speter ``/mx host'' returns the MX records for ``host''. 711138032Speter ``/parse address'' will parse address, returning the value of 711238032Speter crackaddr (essentially, the comment information) 711338032Speter and the parsed address. 711438032Speter ``/try mailer address'' will rewrite address into the form 711538032Speter it will have when presented to the indicated mailer. 711638032Speter ``/tryflags flags'' will set flags used by parsing. The 711738032Speter flags can be `H' for header or `E' for envelope, 711838032Speter and `S' for sender or `R' for recipient. These 711938032Speter can be combined, so `HR' sets flags for header 712038032Speter recipients. 712138032Speter ``/canon hostname'' will try to canonify hostname and 712238032Speter return the result. 712338032Speter ``/map mapname key'' will look up `key' in the indicated 712438032Speter `mapname' and return the result. 712538032Speter Somewhat better handling of UNIX-domain socket addresses -- it 712638032Speter should show the pathname rather than hex bytes. 712738032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 712864562Sgshapiro the header for envelope sender information and uses 712938032Speter CR-LF as message terminators. It was thought to be 713038032Speter obsolete (used only for Arpanet NCP protocols), but it 713138032Speter turns out that the UK ``Grey Book'' protocols require 713238032Speter that functionality. 713338032Speter Fix a fix in previous release -- if gethostname and gethostbyname 713438032Speter return a name without dots, and if an attempt to canonify 713538032Speter that name fails, wait one minute and try again. This can 713638032Speter result in an extra 60 second delay on startup if your system 713738032Speter hostname (as returned by hostname(1)) has no dot and no names 713838032Speter listed in /etc/hosts or your NIS map have a dot. 713938032Speter Check for proper domain name on HELO and EHLO commands per 714038032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 714138032Speter of Michigan Technological University. 714238032Speter Relax chownsafe rules slightly -- old version said that if you 714338032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 714438032Speter if fpathconf returned EINVAL or ENOSYS), assume that 714538032Speter chown is not safe. The new version falls back to whether 714638032Speter you are on a BSD system or not. This is important for 714738032Speter SunOS, which apparently always returns one of those 714838032Speter error codes. This impacts whether you can mail to files 714938032Speter or not. 715038032Speter Syntax errors such as unbalanced parentheses in the configuration 715138032Speter file could be omitted if you had "Oem" prior to the 715238032Speter syntax error in the config file. Change to always print 715338032Speter the error message. It was especially weird because it 715438032Speter would cause a "warning" message to be sent to the Postmaster 715538032Speter for every message sent (but with no transcript). Problem 715638032Speter noted by Gregory Paris of Motorola. 715738032Speter Rewrite collect and putbody to handle full 8-bit data, including 715838032Speter zero bytes.

This is to handle the 722738032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 722838032Speter assume that ``group name:'' is a comment on the first 722938032Speter address and the ``;'' is a comment on the last address). 723038032Speter This requires config file support to get right.

This borrows ideas from 725738032Speter John Beck of Hewlett-Packard, who generously contributed 725838032Speter their implementation to me, which I then didn't use (see 725938032Speter mime.c for an explanation of why). This adds the 726038032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 726138032Speter to control handling of 8-bit data. These have to cope with 726238032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 726338032Speter 8-bit data that is entered without declaring it as 8-bit 726438032Speter MIME -- technically this is illegal according to the 726538032Speter specs) and labelled 8-bit data (that is, it was declared 726638032Speter as 8BITMIME in the ESMTP session or by using the 726738032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 726838032Speter set then 8-bit data is sent to non-8BITMIME machines 726938032Speter instead of converting to 7 bit (essentially using 727038032Speter just-send-8 semantics). The values for EightBitMode are: 727138032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 727238032Speter any necessary conversion of 8BITMIME to 7BIT 727338032Speter (essentially, the full MIME option). 727438032Speter p pass unlabelled 8-bit input, but convert labelled 727538032Speter 8BITMIME input to 7BIT as required (default). 727638032Speter s strict adherence: reject unlabelled 8-bit input, 727738032Speter convert 8BITMIME to 7BIT as required. The F=8 727838032Speter flag is ignored. 727938032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 728038032Speter the setting of F=8. 728138032Speter Add new internal class 'n', which is the set of MIME Content-Types 728238032Speter which can not be 8 to 7 bit encoded because of other 728338032Speter considerations. Types "multipart/*" and "message/*" are 728438032Speter never directly encoded (although their components can be). 728538032Speter Add new internal class 's', which is the set of subtypes of the 728638032Speter MIME message/* content type that can be treated as though 728738032Speter they are an RFC822 message. It is predefined to have 728838032Speter "rfc822". Suggested By Kari Hurtta. 728938032Speter Add new internal class 'e'. This is the set of MIME 729038032Speter Content-Transfer-Encodings that can be converted to 729138032Speter a seven bit format (Quoted-Printable or Base64). It is 729238032Speter preinitialized to contain "7bit", "8bit", and "binary". 729338032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 729438032Speter short name) to set the default character set to use in the 729538032Speter Content-Type: header when doing encoding of an 8-bit message 729638032Speter which isn't marked as MIME into MIME format. If the C= 729738032Speter parameter is set on the Envelope From address, use that as 729838032Speter the default encoding; else use the DefaultCharSet option. 729938032Speter If neither is set, it defaults to "unknown-8bit" as 730038032Speter suggested by RFC 1428 section 3. 730138032Speter Allow ``U=user:group'' field in mailer definition to set a default 730238032Speter user and group that a mailer will be executed as. This 730338032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 730438032Speter also set, it is the uid/gid that will always be used (that 730538032Speter is, the controlling address is ignored). The values may be 730638032Speter numeric or symbolic; if only a symbolic user is given (no 730738032Speter group) that user's default group in the passwd file is used 730838032Speter as the group. Based on code donated by Chip Rosenthal of 730938032Speter Unicom. 731038032Speter Allow `u' option to also accept user:group as a value, in the same 731138032Speter fashion as the U= mailer option. 731238032Speter Add the symbolic time zone name in the Arpanet format dates (as 731338032Speter a comment). This adds a new compile-time configuration 731438032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 731538032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 731638032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 731738032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 731838032Speter timezone()), or TZ_NONE (don't include the comment). Code 731938032Speter from Chip Rosenthal. 732038032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 732138032Speter For example, 732238032Speter O Timeout.helo = 2m 732338032Speter There are also two new suboptions "queuereturn" and 732438032Speter "queuewarn"; these subsume the old T option. Thus, to 732538032Speter set them both the preferred new syntax is 732638032Speter O Timeout.queuereturn = 5d 732738032Speter O Timeout.queuewarn = 4h 732838032Speter Sort queue by host name instead of by message priority if the 732938032Speter QueueSortOrder option (no short name) is set is set to 733038032Speter ``host''. This makes better use of the connection cache, 733138032Speter but may delay more ``interactive'' messages behind large 733238032Speter backlogs under some circumstances. This is probably a 733338032Speter good option if you have high speed links or don't do lots 733438032Speter of ``batch'' messages, but less good if you are using 733538032Speter something like PPP on a 14.4 modem. Based on code 733638032Speter contributed by Roy Mongiovi of Georgia Tech (my main 733738032Speter contribution was to make it configurable). 733838032Speter Save i-number of df file in qf file to simplify rebuilding of queue 733938032Speter after disastrous disk crash. Suggested by Kyle Jones of 734038032Speter UUNET; closely based on code from KJS DECWRL code written 734138032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 734238032Speter are NOT back compatible with 8.6 -- that is, you can convert 734338032Speter from 8.6 to 8.7, but not the other direction. 734438032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 734538032Speter route-addrs in envelopes; this is because in some cases 734638032Speter they can be sent to the shell, which interprets them as 734738032Speter I/O redirection. 734838032Speter Don't include error file (option E) with return-receipts; this 734938032Speter can be confusing. 735038032Speter Don't send "Warning: cannot send" messages to owner-* or 735138032Speter *-request addresses. Suggested by Christophe Wolfhugel 735238032Speter of the Institut Pasteur, Paris. 735338032Speter Allow -O command line flag to set long form options. 735438032Speter Add "MinQueueAge" option to set the minimum time between attempts 735538032Speter to run the queue. For example, if the queue interval 735638032Speter (-q value) is five minutes, but the minimum queue age 735738032Speter is fifteen minutes, jobs won't be tried more often than 735838032Speter once every fifteen minutes. This can be used to give 735938032Speter you more responsiveness if your delivery mode is set to 736038032Speter queue-only. 736138032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 736238032Speter :include: and .forward files. 736338032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 736438032Speter key field name, the value field name, and the field 736538032Speter delimiter. The field delimiter can be a single character 736638032Speter or the sequence "\t" or "\n" for tab or newline. 736743730Speter These are for use by NIS+ and similar access methods. 736838032Speter Change maps to always strip quotes before lookups; the -q flag 736938032Speter turns off this behavior. Suggested by Motonori Nakamura. 737038032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 737138032Speter key and value field names respectively. Code donated by 737238032Speter Sun Microsystems. 737338032Speter Add "hesiod" map class. The "file name" is used as the 737438032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 737538032Speter first value found for the match. Code donated by Scott 737638032Speter Hutton of Indiana University. 737738032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 737838032Speter specify the name of the property that is searched as the 737938032Speter key and a -v flag to specify the name of the property that 738038032Speter is returned as the value (defaults to "members"). The 738138032Speter default map is "/aliases". Some code based on code 738238032Speter contributed by Robert La Ferla of Hot Software. 738338032Speter Add "text" map class. This does slow, linear searches through 738438032Speter text files. The -z flag specifies a column delimiter 738538032Speter (defaults to any sequence of white space), the -k flag 738638032Speter sets the key column number, and the -v flag sets the 738738032Speter value column number. Lines beginning with `#' are treated 738838032Speter as comments. 738938032Speter Add "program" map class to execute arbitrary programs. The search 739038032Speter key is presented as the last argument; the output is one 739138032Speter line read from the programs standard output. Exit statuses 739238032Speter are from sysexits.h. 739338032Speter Add "sequence" map class -- searches maps in sequence until it 739438032Speter finds a match. For example, the declarations: 739538032Speter Kmap1 ... 739638032Speter Kmap2 ... 739738032Speter Kmapseq sequence map1 map2 739838032Speter defines a map "mapseq" that first searches map1; if the 739938032Speter value is found it is returned immediately, otherwise 740038032Speter map2 is searched and the value returned. 740138032Speter Add "switch" map class. This is much like "sequence" except that 740238032Speter the ordering is fetched from an external file, usually 740338032Speter the system service switch. The parameter is the name of 740438032Speter the service to switch on, and the maps that it will use 740538032Speter are the name of the switch map followed by ".service_type". 740638032Speter For example, if the declaration of the map is 740738032Speter Ksample switch hosts 740838032Speter and the system service switch specifies that hosts are 740938032Speter looked up using dns and nis in that order, then this is 741038032Speter equivalent to 741138032Speter Ksample sequence sample.dns sample.nis 741238032Speter The subordinate maps (sample.*) must already be defined. 741338032Speter Add "user" map class -- looks up users using getpwnam. Takes a 741438032Speter "-v field" flag on the definition that tells what passwd 741538032Speter entry to return -- legal values are name, passwd, uid, gid, 741638032Speter gecos, dir, and shell. Generally expected to be used with 741738032Speter the -m (matchonly) flag. 741838032Speter Add "bestmx" map class -- returns the best MX value for the host 741938032Speter listed as the value. If there are several "best" MX records 742038032Speter for this host, one will be chosen at random. 742138032Speter Add "userdb" map class -- looks up entries in the user database. 742238032Speter The "file name" is actually the tag that will be used, 742338032Speter typically "mailname". If there are multiple entries 742438032Speter matching the name, the one chosen is undefined. 742538032Speter Add multiple queue timeouts (both return and warning). These are 742638032Speter set by the Precedence: or Priority: header fields to one of 742738032Speter three values. If a Priority: is set and has value "normal", 742838032Speter "urgent", or "non-urgent" the corresponding timeouts are 742938032Speter used. If no priority is set, the Precedence: is consulted; 743038032Speter if negative, non-urgent timeouts are used; if greater than 743138032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 743238032Speter are used. The timeouts are set by setting the six timeouts 743338032Speter queue{warn,return}.{urgent,normal,non-urgent}. 743438032Speter Fix problem when a mail address is resolved to a $#error mailer 743538032Speter with a temporary failure indication; it works in SMTP, 743638032Speter but when delivering locally the mail is silently discarded. 743738032Speter This patch, from Kyle Jones of UUNET, bounces it instead 743838032Speter of queueing it (queueing is very hard). 743938032Speter When using /etc/hosts or NIS-style lookups, don't assume that 744038032Speter the first name in the list is the best one -- instead, 744138032Speter search for the first one with a dot. For example, if 744238032Speter an /etc/hosts entry reads 744338032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 744438032Speter this change will use the second name as the canonical 744538032Speter machine name instead of the initial, unqualified name. 744638032Speter Change dequote map to replace spaces in quoted text with a value 744738032Speter indicated by the -s flag on the dequote map definition. 744838032Speter For example, ``Mdequote dequote -s_'' will change 744938032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 745038032Speter quoted (because of the space character). Suggested by Dan 745138032Speter Oscarsson for use in X.400 addresses. 745238032Speter Implement long macro names as ${name}; long class names can 745338032Speter be similarly referenced as $={name} and $~{name}. 745438032Speter Definitions are (e.g.) ``D{name}value''. Names that have 745538032Speter a leading lower case letter or punctuation characters are 745638032Speter reserved for internal use by sendmail; i.e., config files 745738032Speter should use names that begin with a capital letter. Based 745838032Speter on code contributed by Dan Oscarsson. 745938032Speter Fix core dump if getgrgid returns a null group list (as opposed 746038032Speter to an empty group list, that is, a pointer to a list 746138032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 746238032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 746338032Speter failed, it called syserr which called newstr which called 746438032Speter xalloc.... The newstr is now avoided for "panic" messages. 746538032Speter Reported by Stuart Kemp of James Cook University. 746638032Speter Improve connection cache timeouts; previously, they were not even 746738032Speter checked if you were delivering to anything other than an 746838032Speter IPC-connected host, so a series of (say) local mail 746938032Speter deliveries could cause cached connections to be open 747038032Speter much longer than the specified timeout. 747138032Speter If an incoming message exceeds the maximum message size, stop 747238032Speter writing the incoming bytes to the queue data file, since 747338032Speter this can fill your mqueue partition -- this is a possible 747438032Speter denial-of-service attack. 747538032Speter Don't reject all numeric local user names unless HESIOD is 747638032Speter defined. It turns out that Posix allows all-numeric 747738032Speter user names. Fix from Tony Sanders of BSDI. 747838032Speter Add service switch support. If the local OS has a service 747938032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 748038032Speter on DEC systems) that will be used; otherwise, it falls back 748138032Speter to using a local mechanism based on the ServiceSwitchFile 748238032Speter option (default: /etc/service.switch). For example, if the 748338032Speter service switch lists "files" and "nis" for the aliases 748438032Speter service, that will be the default lookup order. the "files" 748538032Speter ("local" on DEC) service type expands to any alias files 748638032Speter you listed in the configuration file, even if they aren't 748738032Speter actually file lookups. 748838032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 748938032Speter variable which tells whether or not DNS should be considered 749038032Speter canonical. This is now determined based on whether or not 749138032Speter "dns" is in the service list for "hosts". 749238032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 749338032Speter Status Notifications). DSN notifications override 749438032Speter Return-Receipt-To: headers, which are bogus anyhow -- 749538032Speter support for them has been removed. 749638032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 749738032Speter definitions to define the types used in DSN returns for 749838032Speter MTA names, addresses, and diagnostics respectively. 749938032Speter Extend heuristic to force running in ESMTP mode to look for the 750038032Speter five-character string "ESMTP" anywhere in the 220 greeting 750138032Speter message (not just the second line). This is to provide 750238032Speter better compatibility with other ESMTP servers. 750338032Speter Print sequence number of job when running the queue so you can 750438032Speter easily see how much progress you have made. Suggested 750538032Speter by Peter Wemm of DIALix. 750638032Speter Map newlines to spaces in logged message-ids; some versions of 750738032Speter syslog truncate the rest of the line after newlines. 750838032Speter Suggested by Fletcher Mattox of U. Texas. 750938032Speter Move up forking for job runs so that if a message is split into 751038032Speter multiple envelopes you don't get "fork storms" -- this 751138032Speter also improves the connection cache utilization. 751238032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 751338032Speter the purposes of refusing to send error returns. Suggested 751438032Speter by Motonori Nakamura of Ritsumeikan University. 751538032Speter Relax rules on when a file can be written when referenced from 751638032Speter the aliases file: use the default uid/gid instead of the 751738032Speter real uid/gid. This allows you to create a file owned by 751838032Speter and writable only by the default uid/gid that will work 751938032Speter all the time (without having the set-user-ID bit set). Change 752038032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 752138032Speter Microsystems. 752238032Speter Add "DialDelay" option (no short name) to provide an "extra" 752338032Speter delay for dial on demand systems. If this is non-zero 752438032Speter and a connect fails, sendmail will wait this long and 752538032Speter then try again. If it takes longer than the kernel 752638032Speter timeout interval to establish the connection, this 752738032Speter option can give the network software time to establish 752838032Speter the link. The default units are seconds. 752938032Speter Move logging of sender information to be as early as possible; 753038032Speter previously, it could be delayed a while for SMTP mail 753138032Speter sent to aliases. Suggested by Brad Knowles of the 753243730Speter Defense Information Systems Agency. 753338032Speter Call res_init() before setting RES_DEBUG; this is required by 753438032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 753538032Speter the National Computer Security Center. 753638032Speter Add xdelay= field in logs -- this is a transaction delay, telling 753738032Speter you how long it took to deliver to this address on the 753838032Speter last try. It is intended to be used for sorting mailing 753938032Speter lists to favor "quick" addresses. Provided for use by 754038032Speter the mailprio scripts (see below). 754138032Speter If a map cannot be opened, and that map is non-optional, and 754238032Speter an address requires that map for resolution, queue the 754338032Speter map instead of bouncing it. This involves creating a 754438032Speter pseudo-class of maps called "bogus-map" -- if a required 754538032Speter map cannot be opened, the class is changed to bogus-map; 754638032Speter all queries against bogus-map return "tempfail". The 754738032Speter bogus-map class is not directly accessible. A sample 754838032Speter implementation was donated by Jem Taylor of Glasgow 754938032Speter University Computing Service. 755038032Speter Fix a possible core dump when mailing to a program that talks 755138032Speter SMTP on its standard input. Fix from Keith Moore of 755238032Speter the University of Kentucky. 755338032Speter Make it possible to resolve filenames to $#local $: @ /filename; 755438032Speter previously, the "@" would cause it to not be recognized 755538032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 755638032Speter Accept a -1 signal to re-exec the daemon. This only works if 755738032Speter argv[0] is a full path to sendmail. 755838032Speter Fix bug in "addr=..." field in O option on little-endian machines 755938032Speter -- the network number wasn't being converted to network 756038032Speter byte order. Patch from Kurt Lidl of Pix Technologies 756138032Speter Corporation. 756238032Speter Pre-initialize the resolver early on; this is to avoid a bug with 756338032Speter BIND 4.9.3 that can cause the _res.retry field to get 756438032Speter reset to zero, causing all name server lookups to time 756538032Speter out. Fix from Matt Day of Artisoft. 756638032Speter Restore T line (trusted users) in config file -- but instead of 756738032Speter locking out the -f flag, they just tell whether or not 756838032Speter an X-Authentication-Warning: will be added. This really 756938032Speter just creates new entries in class 't', so "Ft/file/name" 757038032Speter can be used to read trusted user names from a file. 757138032Speter Trusted users are also allowed to execute programs even 757238032Speter if they have a shell that isn't in /etc/shells. 757338032Speter Improve NEWDB alias file rebuilding so it will create them 757438032Speter properly if they do not already exist. This had been 757538032Speter a MAYBENEXTRELEASE feature in 8.6.9. 757638032Speter Check for @:@ entry in NIS maps before starting up to avoid 757738032Speter (but not prevent, sigh) race conditions. This ought to 757838032Speter be handled properly in ypserv, but isn't. Suggested by 757938032Speter Michael Beirne of Motorola. 758038032Speter Refuse connections if there isn't enough space on the filesystem 758138032Speter holding the queue. Contributed by Robert Dana of Wolf 758238032Speter Communications. 758338032Speter Skip checking for directory permissions in the path to a file 758438032Speter when checking for file permissions iff setreuid() 758538032Speter succeeded -- it is unnecessary in that case. This avoids 758638032Speter significant performance problems when looking for .forward 758738032Speter files. Based on a suggestion by Win Bent of USC. 758838032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 758938032Speter arbitrary ruleset number assigned or "Sname = integer" 759038032Speter to assign a specific ruleset number. Reference is 759164562Sgshapiro $>name_or_number. Names can be composed of alphas, digits, 759238032Speter underscore, or hyphen (first character must be non-numeric). 759338032Speter Allow -o flag on AliasFile lines to make the alias file optional. 759438032Speter From Bryan Costales of ICSI. 759538032Speter Add NoRecipientAction option to handle the case where there is 759638032Speter no legal recipient header in the message. It can take 759738032Speter on values: 759838032Speter None Leave the message as is. The 759938032Speter message will be passed on even 760038032Speter though it is in technically 760138032Speter illegal syntax. 760238032Speter Add-To Add a To: header with any 760338032Speter recipients that it can find from 760438032Speter the envelope. This risks exposing 760538032Speter Bcc: recipients. 760638032Speter Add-Apparently-To Add an Apparently-To: header. This 760738032Speter has almost no redeeming social value, 760838032Speter and is provided only for back 760938032Speter compatibility. 761038032Speter Add-To-Undisclosed Add a header reading 761138032Speter To: undisclosed-recipients:; 761238032Speter which will have the effect of 761338032Speter making the message legal without 761438032Speter exposing Bcc: recipients. 761538032Speter Add-Bcc To add an empty Bcc: header. 761638032Speter There is a chance that mailers down 761738032Speter the line will delete this header, 761838032Speter which could cause exposure of Bcc: 761938032Speter recipients. 762038032Speter The default is NoRecipientAction=None. 762138032Speter Truncate (rather than delete) Bcc: lines in the header. This 762238032Speter should prevent later sendmails (at least, those that don't 762338032Speter themselves delete Bcc:) from considering this message to 762438032Speter be non-conforming -- although it does imply that non-blind 762538032Speter recipients can see that a Bcc: was sent, albeit not to whom. 762638032Speter Add SafeFileEnvironment option. If declared, files named as delivery 762738032Speter targets must be regular files in addition to the regular 762838032Speter checks. Also, if the option is non-null then it is used as 762938032Speter the name of a directory that is used as a chroot(2) 763038032Speter environment for the delivery; the file names listed in an 763138032Speter alias or forward should include the name of this root. 763238032Speter For example, if you run with 763338032Speter O SafeFileEnvironment=/arch 763438032Speter then aliases should reference "/arch/rest/of/path". If a 763538032Speter value is given, sendmail also won't try to save to 763638032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 763738032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 763838032Speter Support -A flag for alias files; this will comma concatenate like 763938032Speter entries. For example, given the aliases: 764038032Speter list: member1 764138032Speter list: member2 764238032Speter and an alias file declared as: 764338032Speter OAhash:-A /etc/aliases 764438032Speter the final alias inserted will be "list: member1,member2"; 764538032Speter without -A you will get an error on the second and subsequent 764638032Speter alias for "list".

Suggested by Liudvikas Bukys. 764838032Speter Fix a problem that could cause very long addresses to core dump in 764938032Speter some special circumstances. Problem pointed out by Allan 765038032Speter Johannesen. 765138032Speter (Internal change.) Change interface to expand() (macro expansion) 765238032Speter to be simpler and more consistent. 765338032Speter Delete check for funny qf file names. This didn't really give 765438032Speter any extra security and caused some people some problems. 765538032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 765638032Speter at compile time.) Suggested by Kyle Jones of UUNET. 765738032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 765838032Speter merge with DSN code; this is simpler and more consistent. 765938032Speter This may affect some people who have written their own 766038032Speter checkcompat() routine. 766138032Speter (Internal change.) Eliminate `D' line in qf file. The df file 766238032Speter is now assumed to be the same name as the qf file (with 766338032Speter the `q' changed to a `d', of course). 766438032Speter Avoid forking for delivery if all recipient mailers are marked as 766538032Speter "expensive" -- this can be a major cost on some systems. 766638032Speter Essentially, this forces sendmail into "queue only" mode 766738032Speter if all it is going to do is queue anyway. 766838032Speter Avoid sending a null message in some rather unusual circumstances 766938032Speter (specifically, the RCPT command returns a temporary 767038032Speter failure but the connection is lost before the DATA 767138032Speter command). Fix from Scott Hammond of Secure Computing 767238032Speter Corporation. 767338032Speter Change makesendmail to use a somewhat more rational naming scheme: 767438032Speter Makefiles and obj directories are named $os.$rel.$arch, 767538032Speter where $os is the operating system (e.g., SunOS), $rel is 767638032Speter the release number (e.g., 5.3), and $arch is the machine 767738032Speter architecture (e.g., sun4). Any of these can be omitted, 767838032Speter and anything after the first dot in a release number can 767938032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 768038032Speter version used $os.$arch.$rel and was rather less general. 768138032Speter Change makesendmail to do a "make depend" in the target directory 768290792Sgshapiro when it is being created. This involves adding an empty 768338032Speter "depend:" entry in most Makefiles. 768438032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 768538032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 768638032Speter of the Finnish Meteorological Institute. 768738032Speter Fix problem that could cause multiple responses to DATA command 768838032Speter on header syntax errors (e.g., lines beginning with colons). 768938032Speter Problem noted by Jens Thomassen of the University of Oslo. 769038032Speter Don't let null bytes in headers cause truncation of the rest of 769138032Speter the header. 769238032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 769338032Speter Increase timeouts on message data puts to allow time for receivers 769438032Speter to canonify addresses in headers on the fly. This is still 769538032Speter a rather ugly heuristic. From Motonori Nakamura. 769638032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 769738032Speter records are not used when canonifying names, and when MX 769838032Speter lookups are done for addressing they must be fully 769938032Speter qualified. This is useful if you have a wildcard MX record, 770038032Speter although it may cause other problems. In general, don't use 770138032Speter wildcard MX records. Patch from Motonori Nakamura. 770238032Speter Eliminate default two-line SMTP greeting message. Instead of 770338032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 770438032Speter is added between the first and second word of the first 770538032Speter line of the greeting message (i.e., immediately after the 770638032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 770738032Speter compile flag. Old sendmails won't see the ESMTP, but that's 770838032Speter acceptable because SIZE was the only useful extension that 770938032Speter old sendmails understand. 771038032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 771138032Speter invoked state dumps. From Masaharu Onishi. 771238032Speter Allow on-line comments in .forward and :include: files; they are 771338032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 771438032Speter is a space or a tab. This is intended for native 771538032Speter representation of non-ASCII sets such as Japanese, where 771638032Speter existing encodings would be unreadable or would lose 771738032Speter data -- for example, 771838032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 771938032Speter (romanized/less information) 772038032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 772138032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 772238032Speter (with MIME encoding, not human readable) 772338032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 772438032Speter (native encoding with ISO-2022-JP) 772538032Speter The last form is human readable in the Japanese environment. 772638032Speter Based on a fix from (surprise!) Motonori Nakamura. 772738032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 772838032Speter messages to that host; these are most frequently associated 772938032Speter with addresses rather than the host, with the exception of 773038032Speter 421 (service shutting down). The effect was to cause queues 773138032Speter to sometimes take an excessive time to flush. Reported by 773238032Speter Robert Sargent of Southern Geographics Technologies and 773338032Speter Eric Prestemon of American University. 773438032Speter Add Nice=N mailer option to set the niceness at which a mailer will 773538032Speter run. This is actually a relative niceness (that is, an 773638032Speter increment on the background value). 773738032Speter Log queue runs that are skipped due to high loads. They are logged 773838032Speter at LOG_INFO priority iff the log level is > 8. Contributed 773938032Speter by Bruce Nagel of Data General. 774038032Speter Allow the error mailer to accept a DSN-style error status code 774138032Speter instead of an sysexits status code in the host part. 774238032Speter Anything with a dot will be interpreted as a DSN-style code. 774338032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 774438032Speter to encode characters that might be munged by an EBCDIC system 774538032Speter in addition to the set required by RFC 1521. The additional 774638032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 774738032Speter (Think of "IBM 360" as the mnemonic for this flag.) 774838032Speter Change check for mailing to files to look for a pathname of [FILE] 774938032Speter rather than looking for the mailer named *file*. The mapping 775038032Speter of leading slashes still goes to the *file* mailer. This 775138032Speter allows you to implement the *file* mailer as a separate 775238032Speter program, for example, to insert a Content-Length: header 775338032Speter or do special security policy. However, note that the usual 775438032Speter initial checking for the file permissions is still done, and 775538032Speter the program in question needs to be very careful about how 775638032Speter it does the file write to avoid security problems. 775738032Speter Be able to read ~root/.forward even if the path isn't accessible to 775838032Speter regular users. This is disrecommended because sendmail 775938032Speter sometimes does not run as root (e.g., when an unsafe option 776038032Speter is specified on the command line), but should otherwise be 776138032Speter safe because .forward files must be owned by the user for 776238032Speter whom mail is being forwarded, and cannot be a symbolic link. 776338032Speter Suggested by Forrest Aldrich of Wang Laboratories. 776438032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 776538032Speter file. This is used for canonifying hostnames when the 776638032Speter service type is "files". 776738032Speter Implement programs on F (read class from file) line. The syntax is 776838032Speter Fc|/path/to/program to read the output from the program 776938032Speter into class "c". 777038032Speter Probe the network interfaces to find alternate names for this 777138032Speter host. Requires the SIOCGIFCONF ioctl call. Code 777238032Speter contributed by SunSoft. 777338032Speter Add "E" configuration line to set or propagate environment 777438032Speter variables into children. "E<envar>" will propagate 777538032Speter the named variable from the environment when sendmail 777638032Speter was invoked into any children it calls; "E<envar>=<value>" 777738032Speter sets the named variable to the indicated value. Any 777838032Speter variables not explicitly named will not be in the child 777938032Speter environment. However, sendmail still forces an 778038032Speter "AGENT=sendmail" environment variable, in part to enforce 778138032Speter at least one environment variable, since many programs and 778238032Speter libraries die horribly if this is not guaranteed. 778338032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 778438032Speter alias databases -- new algorithm looks for the substring 778538032Speter "/yp/" in the file name. This is more portable and involves 778638032Speter less overhead. Suggested by Motonori Nakamura. 778738032Speter Dynamically allocate the queue work list so that you don't lose 778838032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 778938032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 779038032Speter should not need to be changed) and the MaxQueueRunSize option, 779138032Speter which is the absolute maximum number of jobs that will ever 779238032Speter be handled in a single queue run. Based on code contributed 779338032Speter by Brian Coan of the Institute for Global Communications. 779438032Speter Log message when a message is dropped because it exceeds the maximum 779538032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 779638032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 779738032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 779838032Speter of Mark G. Thomas Consulting. 779938032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 780038032Speter OS-dependent defines). The old semantic of -d0.1 to not 780138032Speter run the daemon in background has been moved to -d99.100, 780238032Speter and the old 52.5 flag (to avoid disconnect() from closing 780338032Speter all output files) has been moved to 52.100. This makes 780438032Speter things more consistent (flags below .100 don't change 780538032Speter semantics) and separates out the backgrounding so that 780638032Speter it doesn't happen automatically on other unrelated debugging 780738032Speter flags. 780838032Speter If -t is used but no addresses are found in the header, give an 780938032Speter error message rather than just doing nothing. Fix from 781038032Speter Motonori Nakamura. 781138032Speter On systems (like SunOS) where the effective gid is not necessarily 781238032Speter included in the group list returned by getgroups(), the 781338032Speter `restrictmailq' option could sometimes cause an authorized 781438032Speter user to not be able to use `mailq'. Fix from Charles Hannum 781538032Speter of MIT. 781638032Speter Allow symbolic service names for [IPC] mailers. Suggested by 781738032Speter Gerry Magennis of Logica International. 781838032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 781938032Speter when running DNS. For example, if the name FTP.Foo.ORG is 782038032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 782138032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 782238032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 782338032Speter This is technically illegal under RFC 822 and 1123, but the 782438032Speter IETF is moving toward legalizing it. Note that turning on 782538032Speter this option is not sufficient to guarantee that a downstream 782638032Speter neighbor won't rewrite the address for you. 782738032Speter Add "-m" flag to makesendmail script -- this tells you what object 782838032Speter directory and Makefile it will use, but doesn't actually do 782938032Speter the make. 783038032Speter Do some additional checking on the contents of the qf file to try 783138032Speter to detect attacks against the qf file. In particular, 783238032Speter abort on any line beginning "From ", and add an "end of 783338032Speter file" line -- any data after that line is prohibited. 783438032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 783538032Speter choices. This can be overridden in the Makefile by using 783638032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 783738032Speter (to the extent that we know it) or by defining 783838032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 783938032Speter sendmail 8 to have more consistent installation instructions. 784038032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 784138032Speter of Sun Microsystems. 784238032Speter Improved symbol table hash function from Eric Wassenaar. This one 784338032Speter is at least 50% faster. 784438032Speter Fix problem that didn't notice that timeout on file open was a 784538032Speter transient error. Fix from Larry Parmelee of Cornell 784638032Speter University. 784738032Speter Allow comments (lines beginning with a `#') in files read for 784838032Speter classes. Suggested by Motonori Nakamura. 784938032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 785038032Speter of dropping out entirely. This makes testing some of the 785138032Speter name server lookups easier to deal with when there are 785238032Speter hung servers. From Motonori Nakamura. 785338032Speter Add new ${opMode} macro that is set to the current operation mode 785438032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 785538032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 785638032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 785738032Speter Kind of like queue-only mode (Odq) except it tries to avoid 785838032Speter any external service requests; for dial-on-demand hosts that 785938032Speter want to minimize DNS lookups when mail is being queued. For 786038032Speter this to work you will also have to make sure that gethostbyname 786138032Speter of your local host name does not do a DNS lookup. 786238032Speter Improved handling of "out of space" conditions from John Myers of 786338032Speter Carnegie Mellon. 786438032Speter Improved security for mailing to files on systems that have fchmod(2) 786538032Speter support. 786638032Speter Improve "cannot send message for N days" message -- now says "could 786738032Speter not send for past N days".

Problem reported by David 787938032Speter James of British Telecom. 788038032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 788138032Speter from Alexander Dupuy of System Management ARTS. 788238032Speter Delete duplicates in MX lists -- believe it or not, there are sites 788338032Speter that list the same host twice in an MX list. This deletion 788438032Speter only works on adjacent preferences, so an MX list that 788538032Speter had A=5, B=10, A=15 would leave both As, but one that had 788638032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 788738032Speter just in case there is something weird I haven't thought of. 788838032Speter Suggested by Barry Shein of Software Tool & Die. 788938032Speter SECURITY: .forward files cannot be symbolic links. If they are, 789038032Speter a bad guy can read your private files. 789138032Speter PORTABILITY FIXES: 789238032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 789338032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 789438032Speter University. This expands the disk size 789538032Speter checking to include all (?) SVR4 configurations. 789638032Speter System V Release 4 from Kimmo Suominen -- initgroups(3) 789738032Speter and setrlimit(2) are both available. 789838032Speter System V Release 4 from sob@sculley.ffg.com -- some versions 789938032Speter apparently "have EX_OK defined in other headerfiles." 790038032Speter Linux Makefile typo. 790138032Speter Linux getusershell(3) is broken in Slackware 2.0 -- 790238032Speter from Andrew Pam of Xanadu Australia. 790338032Speter More Linux tweaking from John Kennedy of California State 790438032Speter University, Chico. 790538032Speter Cray changes from Eric Wassenaar: ``On Cray, shorts, 790638032Speter ints, and longs are all 64 bits, and all structs 790738032Speter are multiples of 64 bits. This means that the 790838032Speter sizeof operator returns only multiples of 8. 790938032Speter This requires adaptation of code that really 791038032Speter deals with 32 bit or 16 bit fields, such as IP 791138032Speter addresses or nameserver fields.'' 791238032Speter DG/UX 5.4.3 from Mark T. Robinson <mtr@ornl.gov>. To 791338032Speter get the old behavior, use -DDGUX_5_4_2. 791438032Speter DG/UX hack: add _FORCE_MAIL_LOCAL_=yes environment 791538032Speter variable to fix bogus /bin/mail behavior. 791638032Speter Tandem NonStop-UX from Rick McCarty <mccarty@mpd.tandem.com>. 791738032Speter This also cleans up some System V Release 4 compile 791838032Speter problems. 791938032Speter Solaris 2: sendmail.cw file should be in /etc/mail to 792038032Speter match all the other configuration files. Fix 792138032Speter from Glenn Barry of Emory University. 792238032Speter Solaris 2.3: compile problem in conf.c. Fix from Alain 792338032Speter Nissen of the University of Liege, Belgium. 792438032Speter Ultrix: freespace calculation was incorrect. Fix from 792538032Speter Takashi Kizu of Osaka University. 792638032Speter SVR4: running in background gets a SIGTTOU because the 792738032Speter emulation code doesn't realize that "getpeername" 792838032Speter doesn't require reading the file. Fix from Peter 792938032Speter Wemm of DIALix. 793038032Speter Solaris 2.3: due to an apparent bug in the socket emulation 793138032Speter library, sockets can get into a "wedged" state where 793238032Speter they just return EPROTO; closing and re-opening the 793338032Speter socket clears the problem. Fix from Bob Manson 793438032Speter of Ohio State University. 793538032Speter Hitachi 3050R & 3050RX running HI-UX/WE2: portability 793638032Speter fixes from Akihiro Hashimoto ("Hash") of Chiba 793738032Speter University. 793838032Speter AIX changes to allow setproctitle to work from Rainer Sch�pf 793938032Speter of Zentrum f�r Datenverarbeitung der Universit�t 794038032Speter Mainz. 794138032Speter AIX changes for load average from Ed Ravin of NASA/Goddard. 794238032Speter SCO Unix from Chip Rosenthal of Unicom (code was using the 794338032Speter wrong statfs call). 794438032Speter ANSI C fixes from Adam Glass (NetBSD project). 794538032Speter Stardent Titan/ANSI C fixes from Kate Hedstrom of Rutgers 794638032Speter University. 794738032Speter DG-UX fixes from Bruce Nagel of Data General. 794838032Speter IRIX64 updates from Mark Levinson of the University of 794938032Speter Rochester Medical Center. 795038032Speter Altos System V (``the first UNIX/XENIX merge the Altos 795138032Speter did for their Series 1000 & Series 2000 line; 795238032Speter their merged code was licensed back to AT&T and 795338032Speter Microsoft and became System V release 3.2'') from 795438032Speter Tim Rice <timr@crl.com>. 795538032Speter OSF/1 running on Intel Paragon from Jeff A. Earickson 795638032Speter <jeff@ssd.intel.com> of Intel Scalable Systems 795738032Speter Division. 795838032Speter Amdahl UTS System V 2.1.5 (SVr3-based) from Janet Jackson 795938032Speter <janet@dialix.oz.au>. 796038032Speter System V Release 4 (statvfs semantic fix) from Alain 796138032Speter Durand of I.M.A.G. 796238032Speter HP-UX 10.x multiprocessor load average changes from 796338032Speter Scott Hutton and Jeff Sumler of Indiana University. 796438032Speter Cray CSOS from Scott Bolte of Cray Computer Corporation. 796538032Speter Unicos 8.0 from Douglas K. Rand of the University of North 796638032Speter Dakota, Scientific Computing Center. 796738032Speter Solaris 2.4 fixes from Sanjay Dani of Dani Communications. 796838032Speter ConvexOS 11.0 from Christophe Wolfhugel. 796938032Speter IRIX 4.0.5 from David Ashton-Reader of CADcentre. 797038032Speter ISC UNIX from J. J. Bailey. 797138032Speter HP-UX 9.xx on the 8xx series machines from Remy Giraud 797238032Speter of Meteo France. 797338032Speter HP-UX configuration from Tom Lane <tgl@sss.pgh.pa.us>. 797438032Speter IRIX 5.2 and 5.3 from Kari E. Hurtta. 797538032Speter FreeBSD 2.0 from Mike Hickey of Federal Data Corporation. 797638032Speter Sony NEWS-OS 4.2.1R and 6.0.3 from Motonori Nakamura. 797738032Speter Omron LUNA unios-b, mach from Motonori Nakamura. 797838032Speter NEC EWS-UX/V 4.2 from Motonori Nakamura. 797938032Speter NeXT 2.1 from Bryan Costales. 798038032Speter AUX patch thanks to Mike Erwin of Apple Computer. 798138032Speter HP-UX 10.0 from John Beck of Hewlett-Packard. 798238032Speter Ultrix: allow -DBROKEN_RES_SEARCH=0 if you are using a 798338032Speter non-DEC resolver. Suggested by Allan Johannesen. 798438032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 798538032Speter University of Brno (Czech Republic). 798638032Speter KSR OS 1.2.2 support from Todd Miller of the University 798738032Speter of Colorado. 798838032Speter UX4800 support from Kazuhisa Shimizu of NEC. 798938032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 799038032Speter in type ``btree'' maps. The semantics of this are undefined 799138032Speter for regular maps, but it can be useful for the user database. 799238032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 799338032Speter lookups while the rebuild is going on. There is a race 799438032Speter condition between the open(... O_TRUNC ...) and the lock 799538032Speter on the file, but it should be quite small. 799638032Speter SMRSH: sendmail restricted shell added to the release. This can 799738032Speter be used as an alternative to /bin/sh for the "prog" mailer, 799838032Speter giving the local administrator more control over what 799938032Speter programs can be run from sendmail. 800038032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 800138032Speter part of the release proper, and isn't fully supported; in 800238032Speter particular, it does not run on System V based systems and 800338032Speter never will. 800438032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 800538032Speter to allow rmail to compile on systems that don't have 800638032Speter function prototypes and systems that don't have snprintf. 800738032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 800838032Speter lists by transaction delay times so that addresses that 800938032Speter respond quickly get sent first. This is to prevent very 801038032Speter sluggish servers from delaying other peoples' mail. 801138032Speter Contributed by Tony Sanders of BSDI. 801238032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 801338032Speter of BSDI. This has a lot of comments to help people out. 801438032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 801538032Speter put this on the m4 command line. On GNU m4 (which 801638032Speter supports the __file__ primitive) you can run m4 in an 801738032Speter arbitrary directory -- use either: 801838032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 801938032Speter or 802038032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 802138032Speter On other versions of m4 that don't support __file__, you 802238032Speter can use: 802338032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 802438032Speter (Note the trailing slash on the _CF_DIR_ definition.) 802538032Speter Old versions of m4 will default to _CF_DIR_=.. for back 802638032Speter compatibility. 802738032Speter CONFIG: fix mail from <> so it will properly convert to 802838032Speter MAILER-DAEMON on local addresses. 802938032Speter CONFIG: fix code that was supposed to catch colons in host 803038032Speter names. Problem noted by John Gardiner Myers of CMU. 803138032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 803238032Speter From Paul Riddle of the University of Maryland, Baltimore 803338032Speter County. 803438032Speter CONFIG: Catch and reject "." as a host address. 803538032Speter CONFIG: Generalize domaintable to look up all domains, not 803638032Speter just unqualified ones. 803738032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 803838032Speter was never used and didn't work anyway. 803938032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 804038032Speter and d on all mailers in the UUCP class. 804138032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 804238032Speter look for an alias for "user+detail", then for "user+*", and 804338032Speter finally for "user". This is intended for forwarding mail 804438032Speter for system aliases such as root and postmaster to a 804538032Speter centralized hub. 804638032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 804738032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 804838032Speter The F=8 flag is also set on the "relay" mailer, since 804938032Speter this is expected to be another sendmail. 805038032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 805138032Speter the name of the UUCP_RELAY -- in some cases, this is the 805238032Speter wrong value (e.g., when we have local UUCP connections), 805338032Speter and this can create unreplyable addresses. From Chip 805438032Speter Rosenthal of Unicom. 805538032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 805638032Speter Received: header inserted into all messages. Suggested by 805738032Speter Gary Mills of the University of Manitoba. 805838032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 805938032Speter to get the old behavior. I did this upon observing 806038032Speter that almost everyone needed this feature, and that the 806138032Speter concept I was trying to make happen didn't work with 806238032Speter some user agents anyway. FEATURE(notsticky) still works, 806338032Speter but it is a no-op. 806438032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 806538032Speter names are sent, rather than immediately diagnosing them 806638032Speter as User Unknown. 806738032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 806838032Speter and RELAY_MAILER_ARGS to set the arguments for the 806938032Speter indicated mailers. All default to "IPC $h". Patch from 807038032Speter Larry Parmelee of Cornell University. 807138032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 807238032Speter on the client side" and F=P to get an appropriate 807338032Speter return-path. From Kimmo Suominen. 807438032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 807538032Speter as the local mailer. For addresses of the form "user+detail" 807643730Speter the "detail" part is passed to procmail via the -a flag. 807738032Speter Contributed by Kimmo Suominen. 807843730Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 807938032Speter use from mailertables. This lets you execute arbitrary 808038032Speter procmail scripts. Contributed by Kimmo Suominen. 808138032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 808238032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 808338032Speter Paul Southworth of CICNet Systems Support. 808438032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 808538032Speter This causes the null return path to be rewritten as 808638032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 808738032Speter From Michael Hohmuth of Technische Universitat Dresden. 808838032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 808938032Speter list us as the best possible MX record to be treated as 809038032Speter though they were local (essentially, assume that they 809138032Speter are included in $=w). This can cause additional DNS 809238032Speter traffic, but is easier to administer if this fits your 809338032Speter local model. It does not work reliably if there are 809438032Speter multiple hosts that share the best MX preference. 809538032Speter Code contributed by John Oleynick of Rutgers. 809638032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 809738032Speter SHell) instead of /bin/sh as the program used for delivery 809838032Speter to programs. If an argument is included, it is used as 809938032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 810038032Speter assumed. 810138032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 810238032Speter size of messages to the local and procmail mailers 810338032Speter respectively. Contributed by Brad Knowles of the Defense 810438032Speter Information Systems Agency. 810538032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 810638032Speter (just like text outside of angle brackets) in order to 810738032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 810838032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 810938032Speter any real systems any more) and tweak the DOMAIN macro 811038032Speter so that it is less likely that users will accidentally use 811138032Speter the Berkeley defaults. Also, create some generic files 811238032Speter that really can be used in the real world. 811338032Speter CONFIG: Add new configuration macros to set character sets for 811438032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 811538032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 811638032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 811738032Speter The old name will still be accepted for a while at least. 811838032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 811938032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 812038032Speter As with all relays, it can be ``mailer:hostname''. Suggested 812138032Speter by Scott Hutton. 812238032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 812338032Speter by Barb Dijker of Labyrinth Computer Services. 812438032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 812538032Speter performance for large alias files, and this confused many 812638032Speter people. 812738032Speter CONFIG: Add confCF_VERSION to append local information to the 812838032Speter configuration version number displayed during SMTP startup. 812938032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 813038032Speter would only work when locally addressed. Fix from 813138032Speter Edvard Tuinder of Cistron Internet Services. 813238032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 813338032Speter "n" (CheckAliases) is set when rebuilding alias database. 813438032Speter Based on code contributed by Claude Marinier. 813538032Speter CONFIG: Allow mailertable to have values of the form 813638032Speter ``error:code message''. The ``code'' is a status code 813738032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 813838032Speter Contributed by David James <dwj@agw.bt.co.uk>. 813938032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 814038032Speter sender domains that will be replaced with the masquerade name. 814138032Speter These domains will not be treated as local, but if mail passes 814238032Speter through with sender addresses in those domains they will be 814338032Speter replaced by the masquerade name. These can also be specified 814438032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 814538032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 814638032Speter as well as the header. Substantial improvements to this 814738032Speter code were contributed by Per Hedeland. 814838032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 814938032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 815038032Speter by Kimmo Suominen. 815138032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 815238032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 815338032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 815438032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 815538032Speter UUCP addressing.

825938032Speter8.6.13/8.6.12 1996/01/25 826038032Speter SECURITY: In some cases it was still possible for an attacker to 826138032Speter insert newlines into a queue file, thus allowing access to 826238032Speter any user (except root). 826338032Speter CONFIG: no changes -- it is not a bug that the configuration 826438032Speter version number is unchanged. 826538032Speter 826638032Speter8.6.12/8.6.12 1995/03/28 826738032Speter Fix to IDENT code (it was getting the size of the reply buffer 826838032Speter too small, so nothing was ever accepted). Fix from several 826938032Speter people, including Allan Johannesen, Shane Castle of the 827038032Speter Boulder County Information Services, and Jeff Smith of 827138032Speter Warwick University (all arrived within a few hours of 827238032Speter each other!). 827338032Speter Fix a problem that could cause large jobs to run out of 827438032Speter file descriptors on systems that use vfork() rather 827538032Speter than fork(). 827638032Speter 827738032Speter8.6.11/8.6.11 1995/03/08 827838032Speter The ``possible attack'' message would be logged more often 827938032Speter than necessary if you are using Pine as a user agent. 828038032Speter The wrong host would be reported in the ``possible attack'' 828138032Speter message when attempted from IDENT. 828238032Speter In some cases the syslog buffer could be overflowed when 828338032Speter reporting the ``possible attack'' message. This can 828438032Speter cause denial of service attacks. Truncate the message 828538032Speter to 80 characters to prevent this problem. 828638032Speter When reading the IDENT response a loop is needed around the 828738032Speter read from the network to ensure that you don't get 828838032Speter partial lines. 828938032Speter Password entries without any shell listed (that is, a null 829038032Speter shell) wouldn't match as "ok". Problem noted by 829138032Speter Rob McMahon. 829238032Speter When running BIND 4.9.x a problem could occur because the 829338032Speter _res.options field is initialized differently than it 829438032Speter was historically -- this requires that sendmail call 829538032Speter res_init before it tweaks any bits. 829643730Speter Fix an incompatibility in openxscript() between the file open mode 829738032Speter and the stdio mode passed to fdopen. This caused UnixWare 829838032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 829938032Speter Novell Labs Europe. 830038032Speter Fix problem with static linking of local getopt routine when 830138032Speter using GNU's ld command. Fix from John Kennedy of 830238032Speter Cal State Chico. 830338032Speter It was possible to turn off privacy flags. Problem noted by 830438032Speter *Hobbit*. 830538032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 830638032Speter and Liudvikas Bukys. 830738032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 830838032Speter from Spider Boardman. 830938032Speter CONFIG: No changes (version number only, to keep it in sync 831038032Speter with the binaries). 831138032Speter 831238032Speter8.6.10/8.6.10 1995/02/10 831338032Speter SECURITY: Diagnose bogus values to some command line flags that 831438032Speter could allow trash to get into headers and qf files. 831538032Speter Validate the name of the user returned by the IDENT protocol. 831638032Speter Some systems that really dislike IDENT send intentionally 831738032Speter bogus information. Problem pointed out by Michael Bushnell 831838032Speter of the Free Software Foundation. Has some security 831938032Speter implications. 832038032Speter Fix a problem causing error messages about DNS problems when 832138032Speter the host name contained a percent sign to act oddly 832238032Speter because it was passed as a printf-style format string. 832338032Speter In some cases this could cause core dumps. 832438032Speter Avoid possible buffer overrun in returntosender() if error 832538032Speter message is quite long. From Fletcher Mattox of the 832638032Speter University of Texas. 832738032Speter Fix a problem that would silently drop "too many hops" error 832838032Speter messages if and only if you were sending to an alias. 832938032Speter From Jon Giltner of the University of Colorado and 833038032Speter Dan Harton of Oak Ridge National Laboratory. 833138032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 833238032Speter set and e->e_message was null. Fix from Bruce Nagel of 833338032Speter Data General. 833438032Speter Fix problem that can still cause df files to be left around 833538032Speter after "hop count exceeded" messages. Fix from Andrew 833638032Speter Chang and Shau-Ping Lo of SunSoft. 833738032Speter Fix a problem that can cause buffer overflows on very long 833838032Speter user names (as might occur if you piped to a program 833938032Speter with a lot of arguments). 834038032Speter Avoid returning an error and re-queueing if the host signature 834138032Speter is null; this can occur on addresses like ``user@.''. 834238032Speter Problem noted by Wesley Craig and the University of 834338032Speter Michigan. 834438032Speter Avoid possible calls to malloc(0) if MCI caching is turned 834538032Speter off. Bug fix from Pierre David of the Laboratoire 834638032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 834738032Speter Universite de Versailles - St Quentin, and Jacky 834838032Speter Thibault. 834938032Speter Make a local copy of the line being sent via senttolist() -- in 835038032Speter some cases, buffers could get trashed by map lookups 835138032Speter causing it to do unexpected things. This also simplifies 835238032Speter some of the map code. 835338032Speter CONFIG: No changes (version number only, to keep it in sync 835438032Speter with the binaries). 835538032Speter 835638032Speter8.6.9/8.6.9 1994/04/19 835738032Speter Do all mail delivery completely disconnected from any terminal. 835838032Speter This provides consistency with daemon delivery and 835938032Speter may have some security implications. 836038032Speter Make sure that malloc doesn't get called with zero size, 836138032Speter since that fails on some systems. Reported by Ed 836238032Speter Hill of the University of Iowa. 836338032Speter Fix multi-line values for $e (SMTP greeting message). Reported 836438032Speter by Mike O'Connor of Ford Motor Company. 836538032Speter Avoid syserr if no NIS domain name is defined, but the map it 836638032Speter is trying to open is optional. From Win Bent of USC. 836738032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 836838032Speter Hesiod support for UDB from Todd Miller of the University of 836938032Speter Colorado. Use "hesiod" as the service name in the U 837038032Speter option. 837138032Speter Fix a problem that failed to set the "authentic" host name (that 837238032Speter is, the one derived from the socket info) if you called 837338032Speter sendmail -bs from inetd. Based on code contributed by 837438032Speter Todd Miller (this problem was also reported by Guy Helmer 837538032Speter of Dakota State University). This also fixes a related 837638032Speter problem reported by Liudvikas Bukys of the University of 837738032Speter Rochester. 837838032Speter Parameterize "nroff -h" in all the Makefiles so people with 837938032Speter variant versions can use them easily. Suggested by 838038032Speter Peter Collinson of Hillside Systems. 838138032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 838238032Speter spaces between parameters instead of one. Reported by 838338032Speter Valdis Kletnieks of Virginia Tech. 838438032Speter Reduce the number of system calls during message collection by 838538032Speter using global timeouts around the collect() loop. This 838638032Speter code was contributed by Eric Wassenaar. 838738032Speter If the initial hostname name gathering results in a name 838838032Speter without a dot (usually caused by NIS misconfiguration) 838938032Speter and BIND is compiled in, directly access DNS to get 839038032Speter the canonical name. This should make life easier for 839138032Speter Solaris systems. If it still can't be resolved, and 839238032Speter if the name server is listed as "required", try again 839338032Speter in 30 seconds. If that also fails, exit immediately to 839438032Speter avoid bogus "config error: mail loops back to myself" 839538032Speter messages. 839638032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 839738032Speter message to explain how much space was available and 839838032Speter sound a bit less threatening. Suggested by Stan Janet 839938032Speter of the National Institute of Standards and Technology. 840038032Speter If mail is delivered to an alias that has an owner, deliver any 840138032Speter requested return-receipt immediately, and strip the 840238032Speter Return-Receipt-To: header from the subsequent message. 840338032Speter This prevents a certain class of denial of service 840438032Speter attack, arguably gives more reasonable semantics, and 840538032Speter moves things more towards what will probably become a 840638032Speter network standard. Suggested by Christopher Davis of 840738032Speter Kapor Enterprises. 840838032Speter Add a "noreceipts" privacy flag to turn off all return receipts 840938032Speter without recompiling. 841038032Speter Avoid printing ESMTP parameters as part of the error message 841138032Speter if there are errors during parsing. This change is 841238032Speter purely cosmetic. 841338032Speter Avoid sending out error messages during the collect phase of 841438032Speter SMTP; there is an MVS mailer from UCLA that gets 841538032Speter confused by this. Of course, I think it's their bug.... 841638032Speter Check for the $j macro getting undefined, losing a dot, or getting 841738032Speter lost from $=w in the daemon before accepting a connection; 841838032Speter if it is, it dumps state, prints a LOG_ALERT message, 841938032Speter and drops core for debugging. This is an attempt to 842038032Speter track down a bug that I thought was long since gone. 842138032Speter If you see this, please forward the log fragment to 842264562Sgshapiro sendmail@sendmail.ORG. 842338032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 842438032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 842538032Speter Wolfhugel. 842638032Speter Instead of trying to truncate the listen queue for the server 842738032Speter SMTP port when the load average is too high, just close 842838032Speter the port completely and reopen it later as needed. 842964562Sgshapiro This ensures that the other end gets a quick "connection 843038032Speter refused" response, and that the connection can be 843138032Speter recovered later. In particular, some socket emulations 843238032Speter seem to get confused if you tweak the listen queue 843338032Speter size around and can never start listening to connections 843438032Speter again. The down side is that someone could start up 843538032Speter another daemon process in the interim, so you could 843638032Speter have multiple daemons all not listening to connections; 843738032Speter this could in turn cause the sendmail.pid file to be 843838032Speter incorrect. A better approach might be to accept the 843938032Speter connection and give a 421 code, but that could break 844064562Sgshapiro other mailers in mysterious ways and have paging behavior 844138032Speter implications. 844238032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 844338032Speter set debugging on the wrong socket. From Eric Wassenaar. 844438032Speter When creating a df* temporary file, be sure you truncate any 844538032Speter existing data in the file -- otherwise system crashes 844638032Speter and the like could result in extra data being sent. 844738032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 844838032Speter doc directory. This includes some additional 844938032Speter information. 845038032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 845138032Speter of recipient envelope addresses. This should have been 845238032Speter handled by the $&h trick, but broke if people were 845338032Speter mixing domainized and UUCP addresses. They should 845438032Speter probably have converted all the way over to uucp-uudom 845538032Speter instead of uucp-{new,old}, but the failure mode was to 845638032Speter loop the mail, which was bad news. 845738032Speter Portability fixes: 845838032Speter Newer BSDI systems (several people). 845938032Speter Older BSDI systems from Christophe Wolfhugel. 846038032Speter Intergraph CLIX, from Paul Southworth of CICNet. 846138032Speter UnixWare, from Evan Champion. 846238032Speter NetBSD from Adam Glass. 846338032Speter Solaris from Quentin Campbell of the University of 846438032Speter Newcastle upon Tyne. 846538032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 846638032Speter Corporation. 846738032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 846838032Speter SunOS (it has setsid() and setvbuf() calls) from 846938032Speter Jonathan Kamens of OpenVision Technologies. 847038032Speter HP-UX from Tor Lillqvist. 847138032Speter New Files: 847238032Speter src/Makefile.CLIX 847338032Speter src/Makefile.NCR3000 847438032Speter doc/changes/Makefile 847564562Sgshapiro doc/changes/changes.me 847638032Speter doc/changes/changes.ps 847738032Speter 847838032Speter8.6.8/8.6.6 1994/03/21 847938032Speter SECURITY: it was possible to read any file as root using the 848038032Speter E (error message) option.

Thanks to Alain Durand of 848638032Speter INRIA for forwarding me the notice from the bugtraq 848738032Speter list. 848838032Speter 848938032Speter8.6.6/8.6.6 1994/03/13 849038032Speter SECURITY: the ability to give files away on System V-based 849138032Speter systems proved dangerous -- don't run as the owner 849238032Speter of a :include: file on a system that allows giveaways. 849338032Speter Unfortunately, this also applies to determining a 849438032Speter valid shell. 849538032Speter IMPORTANT: Previous versions weren't expiring old connections 849638032Speter in the connection cache for a long time under some 849738032Speter circumstances. This could result in resource exhaustion, 849838032Speter both at your end and at the other end. This checks the 849938032Speter connections for timeouts much more frequently. From 850038032Speter Doug Anderson of NCSC. 850138032Speter Fix a glitch that snuck in that caused programs to be run as 850238032Speter the sender instead of the recipient if the mail was 850338032Speter from a local user to another local user. From 850438032Speter Motonori Nakamura of Kyoto University. 850538032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 850638032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 850738032Speter Bryan Costales of ICSI. 850838032Speter Change the method used to declare the "statfs" availability; 850938032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 851038032Speter tweaking in conf.c, there is a single #define called 851138032Speter SFS_TYPE which takes on one of six values (SFS_NONE 851238032Speter for no statfs availability, SFS_USTAT for the ustat(2) 851338032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 851438032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 851538032Speter statfs(2) call with the declarations in <sys/vfs.h>, 851638032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 851738032Speter Fix glitch in NetInfo support that could return garbage if 851838032Speter there was no "/locations/sendmail" property. From 851964562Sgshapiro David Meyer of the University of Virginia. 852038032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 852138032Speter to allow Linux to turn it off even though it is a 852238032Speter BSD-like system. 852338032Speter Allow setting of "ident" timeout to zero to turn off the ident 852438032Speter protocol entirely. 852538032Speter Make 7-bit stripping local to a connection (instead of to a 852638032Speter mailer); this allows you to specify that SMTP is a 852738032Speter 7-bit channel, but revert to 8-bit should it advertise 852838032Speter that it supports 8BITMIME. You still have to specify 852938032Speter mailer flag 7 to get this stripping at all. 853038032Speter Improve makesendmail script so it handles more cases automatically. 853138032Speter Tighten up restrictions on taking ownership of :include: files 853238032Speter to avoid problems on systems that allow you to give away 853338032Speter files. 853438032Speter Fix a problem that made it impossible to rebuild the alias 853538032Speter file if it was on a read-only file system. From 853638032Speter Harry Edmon of the University of Washington. 853738032Speter Improve MX randomization function. From John Gardiner Myers 853838032Speter of CMU. 853938032Speter Fix a minor glitch causing a bogus message to be printed (used 854038032Speter %s instead of %d in a printf string for the line number) 854138032Speter when a bad queue file was read. From Harry Edmon. 854238032Speter Allow $s to remain NULL on locally generated mail. I'm not 854338032Speter sure this is necessary, but a lot of people have complained 854438032Speter about it, and there is a legitimate question as to whether 854538032Speter "localhost" is legal as an 822-style domain. 854638032Speter Fix a problem with very short line lengths (mailer L= flag) in 854738032Speter headers. This causes a leading space to be added onto 854838032Speter continuation lines (including in the body!), and also 854938032Speter tries to wrap headers containing addresses (From:, To:, 855038032Speter etc) intelligently at the shorter line lengths. Problem 855138032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 855238032Speter Log the real user name when logging syserrs, since these can have 855338032Speter security implications. Suggested by several people. 855438032Speter Fix address logging of cached connections -- it used to always 855538032Speter log the numeric address as zero. This is a somewhat 855638032Speter bogus implementation in that it does an extra system 855738032Speter call, but it should be an inexpensive one. Fix from 855838032Speter Motonori Nakamura. 855938032Speter Tighten up handling of short syslog buffers even more -- there 856038032Speter were cases where the outgoing relay= name was too long 856138032Speter to share a line with delay= and mailer= logging. 856238032Speter Limit the overhead on split envelopes to one open file descriptor 856338032Speter per envelope -- previously the overhead was three 856438032Speter descriptors. This was in response to a problem reported 856538032Speter by P{r (Pell) Emanuelsson. 856638032Speter Fixes to better handle the case of unexpected connection closes; 856738032Speter this redirects the output to the transcript so the info 856838032Speter is not lost. From Eric Wassenaar. 856938032Speter Fix potential string overrun if you macro evaluate a string that 857038032Speter has a naked $ at the end. Problem noted by James Matheson 857138032Speter <jmrm@eng.cam.ac.uk>. 857238032Speter Make default error number on $#error messages 553 (``Requested 857338032Speter action not taken: mailbox name not allowed'') instead of 857438032Speter 501 (``Syntax error in parameters or arguments'') to 857538032Speter avoid bogus "protocol error" messages. 857638032Speter Strip off any existing trailing dot on names during $[ ... $] 857738032Speter lookup. This prevents it from ending up with two dots 857838032Speter on the end of dot terminated names. From Wesley Craig 857938032Speter of the University of Michigan and Bryan Costales of ICSI. 858038032Speter Clean up file class reading so that the debugging information is 858138032Speter more informative. It hadn't been using setclass, so you 858238032Speter didn't see the class items being added. 858338032Speter Avoid core dump if you are running a version of sendmail where 858438032Speter NIS is compiled in, and you specify an NIS map, but 858538032Speter NIS is not running. Fix from John Oleynick of 858638032Speter Rutgers. 858738032Speter Diagnose bizarre case where res_search returns a failure value, 858838032Speter but sets h_errno to a success value. 858938032Speter Make sure that "too many hops" messages are considered important 859038032Speter enough to send an error to the Postmaster (that is, the 859138032Speter address specified in the P option). This fix should 859238032Speter help problems that cause the df file to be left around 859338032Speter sometimes -- unfortunately, I can't seem to reproduce 859438032Speter the problem myself. 859538032Speter Avoid core dump (null pointer reference) on EXPN command; this 859638032Speter only occurred if your log level was set to 10 or higher 859738032Speter and the target account was an alias or had a .forward file. 859838032Speter Problem noted by Janne Himanka. 859938032Speter Avoid "denial of service" attacks by someone who is flooding your 860038032Speter SMTP port with bad commands by shutting the connection 860138032Speter after 25 bad commands are issued. From Kyle Jones of 860238032Speter UUNET. 860343730Speter Fix core dump on error messages with very long "to" buffers; 860438032Speter fmtmsg overflows the message buffer. Fixed by trimming 860538032Speter the to address to 203 characters. Problem reported by 860638032Speter John Oleynick. 860738032Speter Fix configuration for HASFLOCK -- there were some spots where 860838032Speter a #ifndef was incorrectly #ifdef. Pointed out by 860938032Speter George Baltz of the University of Maryland. 861038032Speter Fix a typo in savemail() that could cause the error message To: 861138032Speter lists to be incorrect in some places. From Motonori 861238032Speter Nakamura. 861338032Speter Fix a glitch that can cause duplicate error messages on split 861438032Speter envelopes where an address on one of the lists has a 861538032Speter name server failure. Fix from Voradesh Yenbut of the 861638032Speter University of Washington. 861738032Speter Fix possible bogus pointer reference on ESMTP parameters that 861838032Speter don't have an ``=value'' part. 861938032Speter CNAME loops caused an error message to be generated, but also 862038032Speter re-queued the message. Changed to just re-queue the 862138032Speter message (it's really hard to just bounce it because 862238032Speter of the weird way the name server works in the presence 862338032Speter of CNAME loops). Problem noted by James M.R.Matheson 862438032Speter of Cambridge University. 862538032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 862638032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 862738032Speter user name. Suggested by Andreas Stolcke of ICSI. 862838032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 862938032Speter override it easily in the Makefile -- that is, you can 863038032Speter turn it off using -DNAMED_BIND=0. 863138032Speter If a gethostbyname(...) of an address with a trailing dot fails, 863238032Speter try it without the trailing dot. This is because if 863338032Speter you have a version of gethostbyname() that falls back 863438032Speter to NIS or the /etc/hosts file it will fail to find 863538032Speter perfectly reasonable names that just don't happen to 863638032Speter be dot terminated in the hosts file. You don't want to 863738032Speter strip the dot first though because we're trying to ensure 863838032Speter that country names that match one of your subdomains get 863938032Speter a chance. 864038032Speter PRALIASES: fix bogus output on non-null-terminated strings. 864164562Sgshapiro From Bill Gianopoulos of Raytheon. 864238032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 864338032Speter This was in code intended to only catch the self-literal 864438032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 864538032Speter IP address), but the code was broken. However, it will 864664562Sgshapiro still do this if $M is defined; this is necessary to 864738032Speter get client configurations to work (sigh). Note that this 864838032Speter means that $M overrides :mailname entries in the user 864938032Speter database! Problem noted by Paul Southworth. 865038032Speter CONFIG: Fix definition of Solaris help file location. From 865138032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 865264562Sgshapiro CONFIG: Fix bug that broke news.group.USENET mappings. 865338032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 865438032Speter and USENET_MAILER_MAX to tweak the maximum message 865538032Speter size for various mailers. 865638032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 865738032Speter instead of assuming that it is "inews" for consistency 865838032Speter with other mailers. From Michael Corrigan of UC San Diego. 865938032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 866038032Speter qualify the address in the SMTP envelope as user@{relay|hub} 866138032Speter instead of user@$j. From Bill Wisner of The Well. 866238032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 866338032Speter CONFIG: Don't turn off case mapping of user names in the local 866438032Speter mailer for IRIX. This was different than most every other 866538032Speter system. 866638032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 866738032Speter envelope. Noted by Thierry Besancon 866838032Speter <besancon@excalibur.ens.fr>. 866938032Speter CONFIG: Don't include -z by default on uux line -- most systems 867038032Speter don't want it set by default. Pointed out by Philippe 867138032Speter Michel of Thomson CSF. 867238032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 867338032Speter host name was foo.bar.ray.com and you matched against 867438032Speter ".ray.com", the old implementation bound %1 to "bar" 867538032Speter instead of "foo.bar". Also, allow "." in the mailertable 867638032Speter to match anything -- essentially, take over SMART_HOST. 867738032Speter This also moves matching of explicit local host names 867838032Speter before the mailertable so they don't have to be special 867938032Speter cased in the mailertable data. Reported by Bill 868038032Speter Gianopoulos of Raytheon; the fix for the %1 binding 868138032Speter problem was contributed by Nicholas Comanos of the 868238032Speter University of Sydney. 868338032Speter CONFIG: Don't include "root" in class $=L (users to deliver 868438032Speter locally, even if a hub or relay exists) by default. 868538032Speter This is because of the known bug where definition of 868638032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 868738032Speter both and deliver into the local mailbox. 868838032Speter CONFIG: Move up bitdomain and uudomain handling so that they 868938032Speter are done before .UUCP class matching; uudomain was 869038032Speter reported as ineffective before. This also frees up 869138032Speter diversion 8 for future use. Problem reported by Kimmo 869238032Speter Suominen. 869338032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 869438032Speter into host names. As pointed out by Jonathan Kamens, 869538032Speter these are often used because either the forward or reverse 869638032Speter mapping is broken; this translation makes it broken again. 869738032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 869838032Speter Suominen. 869938032Speter Portability fixes: 870038032Speter Unicos from David L.

From 872438032Speter Bob Campbell at U.C. Berkeley. 872538032Speter Security fix: group ids were not completely set when programs 872638032Speter were invoked. This caused programs to have group 872738032Speter permissions they should not have had (usually group 872838032Speter daemon instead of their own group). In particular, 872938032Speter Perl scripts would refuse to run. 873038032Speter Security: check to make sure files that are written are not 873138032Speter symbolic links (at least under some circumstances). 873238032Speter Although this does not respond to a specific known 873338032Speter attack, it's just a good idea. Suggested by 873438032Speter Christian Wettergren. 873538032Speter Security fix: if a user had an NFS mounted home directory on 873638032Speter a system with a restricted shell listed in their 873738032Speter /etc/passwd entry, they could still execute any 873838032Speter program by putting that in their .forward file. 873938032Speter This fix prevents that by insisting that their shell 874038032Speter appear in /etc/shells before allowing a .forward to 874138032Speter execute a program or write a file. You can disable 874238032Speter this by putting "*" in /etc/shells. It also won't 874338032Speter permit world-writable :include: files to reference 874438032Speter programs or files (there's no way to disable this). 874538032Speter These behaviors are only one level deep -- for 874638032Speter example, it is legal for a world-writable :include: 874738032Speter file to reference an alias that writes a file, on 874838032Speter the assumption that the alias file is well controlled. 874938032Speter Security fix: root was not treated suspiciously enough when 875038032Speter looking into subdirectories. This would potentially 875138032Speter allow a cracker to examine files that were publicly 875238032Speter readable but in a non-publicly searchable directory. 875338032Speter Fix a problem that causes an error on QUIT on a cached 875438032Speter connection to create problems on the current job. 875538032Speter These are typically unrelated, so errors occur in 875638032Speter the wrong place. 875738032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 875838032Speter runs more responsive to load average, and fixes a 875938032Speter problem that ignored the load average in locally 876038032Speter generated mail. From Eric Wassenaar. 876138032Speter Fix possible core dump on aliases with null LHS. From 876238032Speter John Orthoefer of BB&N. 876338032Speter Revert to using flock() whenever possible -- there are just 876438032Speter too many bugs in fcntl() locking, particularly over 876538032Speter NFS, that cause sendmail to fail in perverse ways. 876638032Speter Fix a bug that causes the connection cache to get confused 876738032Speter when sending error messages. This resulted in 876838032Speter "unexpected close" messages. It should fix itself 876938032Speter on the following queue run. Problem noted by 877038032Speter Liudvikas Bukys of the University of Rochester. 877138032Speter Include $k in $=k as documented in the Install & Op Guide. 877238032Speter This seems odd, but it was documented.... From 877338032Speter Michael Corrigan of UCSD. 877438032Speter Fix problem that caused :include:s from alias files to be 877538032Speter forced to be owned by root instead of daemon 877638032Speter (actually DefUid). From Tim Irvin. 877738032Speter Diagnose unrecognized I option values -- from Mortin Forssen 877838032Speter of the Chalmers University of Technology. 877938032Speter Make "error" mailer work consistently when there is no error 878038032Speter code associated with it -- previously it returned OK 878138032Speter even though there was a real problem. Now it assumes 878238032Speter EX_UNAVAILABLE. 878338032Speter Fix bug that caused the last header line of messages that had 878438032Speter no body and which were terminated with EOF instead of 878538032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 878638032Speter Fix core dump on SMTP mail to programs that failed -- it tried 878738032Speter to go to a "next MX host" when none existed, causing 878838032Speter a core dump. From der Mouse at McGill University. 878938032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 879038032Speter this makes it easier to turn it off (using 879138032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 879238032Speter Fix YP_MASTER_NAME store to use the unupdated result of 879338032Speter gethostname() (instead of myhostname(), which tries 879438032Speter to fully qualify the name) to be consistent with 879538032Speter SunOS. If your hostname is unqualified, this fixes 879638032Speter transfers to slave servers. Bug noted by Keith 879738032Speter McMillan of Ameritech Services, Inc. 879838032Speter Fix Ultrix problem: gethostbyname() can return a very large 879938032Speter (> 500) h_length field, which causes the sockaddr 880038032Speter to be trashed. Use the size of the sockaddr instead. 880138032Speter Fix from Bob Manson of Ohio State. 880238032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 880338032Speter defined -- this confuses gethostbyname on hosts 880438032Speter file lookups, which doesn't understand the trailing 880538032Speter dot convention. 880638032Speter Log SMTP server subprocesses that die with a signal instead 880738032Speter of from a clean exit. 880838032Speter If you don't have option "I" set, don't assume that a DNS 880938032Speter "host unknown" message is authoritative -- it 881038032Speter might still be found in /etc/hosts. 881138032Speter Fix a problem that would cause Deferred: messages to be sent 881238032Speter as the subject of an error message, even though the 881338032Speter actual cause of a message was more severe than that. 881438032Speter Problem noted by Chris Seabrook of OSSI. 881538032Speter Fix race condition in DBM alias file locking. From Kyle 881638032Speter Jones of UUNET. 881738032Speter Limit delivery syslog line length to avoid bugs in some 881838032Speter versions of syslog(3). This adds a new compile time 881938032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 882038032Speter University, which is in turn derived from IDA. 882138032Speter Fix quotes inside of comments in addresses -- previously 882238032Speter it insisted that they be balanced, but the 822 spec 882338032Speter says that they should be ignored. 882438032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 882538032Speter debugging). This also evaluates ruleset 89, if set 882638032Speter (with the null input), and logs the result. This 882738032Speter should be used sparingly, since the rewrite process 882838032Speter is not reentrant. 882938032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 883038032Speter documented in the Bat Book. 883138032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 883238032Speter return an error message and did not requeue the message. 883338032Speter Fix based on code from Roland Dirlewanger of 883438032Speter Reseau Regional Aquarel, Bordeaux, France. 883538032Speter Fix a problem that caused a seg fault if you got a 421 error 883638032Speter code during some parts of connection initialization. 883738032Speter I've only seen this when talking to buggy mailers on 883838032Speter the other end, but it shouldn't give a seg fault in 883938032Speter any case.

From Vince 887638032Speter DeMarco. 887738032Speter Fix a glitch that sometimes caused :include:s that pointed to 887838032Speter NFS filesystems that were down to give an "aliasing/ 887938032Speter forwarding loop broken" message instead of queueing 888038032Speter the message for retry. Noted by William C Fenner of 888138032Speter the NRL Connection Machine Facility. 888238032Speter Fix a problem that could cause a core dump if the input sequence 888338032Speter had (or somehow acquired) a \231 character. 888464562Sgshapiro Make sure that route-addrs always have <angle brackets> around 888538032Speter them in non-SMTP envelopes (SMTP envelopes already do 888638032Speter this properly). 888738032Speter Avoid weird headers on unbalanced punctuation of the form: 888838032Speter ``Joe User <user)'' -- this caused reference to the 888938032Speter null macro. Fix from Rick McCarty of IO.COM. 889038032Speter Fix a problem that caused an alias "user: user@local.host" to 889138032Speter not have the QNOTREMOTE bit set; this caused configs 889238032Speter to act as if FEATURE(notsticky) was defined even when 889338032Speter it was not. The effect of the problem was to make it 889438032Speter very hard to to set up satellite sites that had a few 889538032Speter local accounts, with everything else forwarded to a 889638032Speter corporate hub. Reported by Detlef Drewanz of the 889738032Speter University of Rostock and Mark Frost of NCD. 889838032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 889938032Speter addresses. This is more efficient (fewer name server 890038032Speter calls) and fixes certain unusual configurations, such 890138032Speter as those that have ruleset 4 do something that is 890238032Speter non-idempotent unless a mailer-specific ruleset did 890338032Speter something else. Problem reported by Brian J. Coan 890438032Speter of the Institute for Global Communications. 890538032Speter Fix the "obsolete argument" routine in main to better understand 890638032Speter new arguments. For example, if you used ``sendmail 890738032Speter -C config -v -q'' it would choke on the -q because 890843730Speter the -C would stop looking for old-format arguments. 890938032Speter Fix the code that was intended to allow two users to forward their 891038032Speter mail to the same program and have them appear unique. 891138032Speter Portability fixes for: 891238032Speter SCO UNIX from Murray Kucherawy. 891338032Speter SCO Open Server 3.2v4 from Philippe Brand. 891438032Speter System V Release 4 from Rick Ellis and others. 891538032Speter OSF/1 from Steve Campbell. 891638032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 891738032Speter of Stoner Associates. 891838032Speter Motorola SysV88 from Kevin Johnson of Motorola. 891938032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 893338032Speter of the config file has moved to /usr/lib 893438032Speter to match the HP-UX version of sendmail. 893538032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 893638032Speter since this is intended only for internal use, the 893738032Speter usual RFC 821/822/1123 rules can be relaxed. The 893838032Speter main point of this is to avoid munging (ugh) UUCP 893938032Speter addresses when relaying internally. 894038032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 894138032Speter syntax addresses delivered via UUCP. Solution 894238032Speter provided by Peter Wemm. 894338032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 894438032Speter zero; it caused double @ signs in addresses. From 894538032Speter Irving Reid of the University of Toronto. 894638032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 894738032Speter from Markku Toijala of ICL Personal Systems Oy. 894838032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 894938032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 895038032Speter that made it hard to recognize your own pseudodomain 895138032Speter names. 895238032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 895338032Speter rather than letting them get "local configuration 895438032Speter error"s. Problem noted by John Gardiner Myers. 895538032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 895638032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 895738032Speter has uucp-dom semantics but old UUCP syntax. This 895838032Speter also permits "uucp-old" as an alias for "uucp" and 895938032Speter "uucp-new" as a synonym for "suucp" for consistency. 896038032Speter CONFIG: add POP mailer support (from Kimmo Suominen 896138032Speter <kim@grendel.lut.fi>). 896238032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 896338032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 896438032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 896538032Speter was set; it would get an additional @masquerade.host 896638032Speter added to the address. Problem noted by Peter Wan 896738032Speter of Georgia Tech. 896838032Speter CONFIG: make sure that the local UUCP name is in $=w. From 896938032Speter Jim Murray of Stratus. 897038032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 897138032Speter mailer flag. Briefly, if you are sending to host 897238032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 897338032Speter "foo!baz" remains "foo!baz", and anything else has 897438032Speter the local name prepended. 897538032Speter CONFIG: portability fixes for HP-UX. 897638032Speter DOC: several minor problems fixed in the Install & Op Guide. 897738032Speter MAKEMAP: fix core dump problem on lines that are too long or 897838032Speter which lack newline. From Mark Delany. 897938032Speter MAILSTATS: print sums of columns (total messages & kbytes 898038032Speter in and out of the system). From Tom Ferrin of UC 898138032Speter San Francisco Computer Graphics Lab. 898238032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 898338032Speter On HP-UX, /etc/sendmail.cf has been moved to 898438032Speter /usr/lib/sendmail.cf to match HP sendmail. 898538032Speter Permissions have been tightened up on world-writable 898638032Speter :include: files and accounts that have shells 898738032Speter that are not listed in /etc/shells. This may 898838032Speter cause some .forward files that have worked 898938032Speter before to start failing. 899038032Speter SIGUSR1 dumps some state to the log. 899138032Speter NEW FILES: 899238032Speter src/Makefile.DGUX 899338032Speter src/Makefile.Dynix 899438032Speter src/Makefile.FreeBSD 899538032Speter src/Makefile.Mach386 899638032Speter src/Makefile.NetBSD 899738032Speter src/Makefile.RISCos 899838032Speter src/Makefile.SCO 899938032Speter src/Makefile.SVR4 900038032Speter src/Makefile.Titan 900138032Speter cf/mailer/pop.m4 900238032Speter cf/ostype/bsdi1.0.m4 900338032Speter cf/ostype/dgux.m4 900438032Speter cf/ostype/dynix3.2.m4 900538032Speter cf/ostype/sco3.2.m4 900638032Speter makemap/Makefile.dist 900738032Speter praliases/Makefile.dist 900838032Speter 900938032Speter8.6.4/8.6.4 1993/10/31 901038032Speter Repair core-dump problem (write to read-only memory segment) 901138032Speter if you fall back to the return-to-Postmaster case in 901238032Speter savemail. Problem reported by Richard Liu. 901338032Speter Immediately diagnose bogus sender addresses in SMTP. This 901438032Speter makes quite certain that crackers can't use this 901538032Speter class of attack. 901638032Speter Reliability Fix: check return value from fclose() and fsync() 901738032Speter in a few critical places. 901838032Speter Minor problem in initsys() that reversed a condition for 901938032Speter redirecting the output channel on queue runs. It's 902038032Speter not clear this code even does anything. From Eric 902138032Speter Wassenaar of the Dutch National Institute for Nuclear 902238032Speter and High-Energy Physics. 902338032Speter Fix some problems that caused queue runs to do "too much work", 902438032Speter such as double-reading the Errors-To: header. From 902538032Speter Eric Wassenaar. 902638032Speter Error messages on writing the temporary file (including the 902738032Speter data file) were getting suppressed in SMTP -- this 902838032Speter fix causes them to be properly reported. From Eric 902938032Speter Wassenaar. 903038032Speter Some changes to support AF_UNIX sockets -- this will only 903138032Speter really become relevant in the next release, but some 903238032Speter people need it for local patches. From Michael 903338032Speter Corrigan of UC San Diego. 903438032Speter Use dynamically allocated memory (instead of static buffers) 903538032Speter for macros defined in initsys() and settime(); since 903638032Speter these can have different values depending on which 903738032Speter envelope they are in. From Eric Wassenaar. 903838032Speter Improve logging to show ctladdr on to= logging; this tells you 903938032Speter what uid/gid processes ran as. 904038032Speter Fix a problem that caused error messages to be discarded if 904138032Speter the sender address was unparseable for some reason; 904238032Speter this was supposed to fall back to the "return to 904338032Speter postmaster" case. 904438032Speter Improve aliaswait backoff algorithm. 904538032Speter Portability patches for Linux (8.6.3 required another header 904638032Speter file) (from Karl London) and SCO UNIX. 904738032Speter CONFIG: patch prog mailer to not strip host name off of envelope 904838032Speter addresses (so that it matches local again). From 904938032Speter Christopher Davis. 905038032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 905138032Speter this prevents uux from seeing lines with null names like 905238032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 905338032Speter Nakamura of Kyoto University. 905438032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 905538032Speter it shouldn't fail miserably. From Motonori Nakamura. 905638032Speter 905738032Speter8.6.2/8.6.2 1993/10/15 905838032Speter Put a "successful delivery" message in the transcript for 905938032Speter addresses that get return-receipts. 906038032Speter Put a prominent "this is only a warning" message in warning 906138032Speter messages -- some people don't read carefully enough 906238032Speter and end up sending the message several times. 906338032Speter Include reason for temporary failure in the "warning" return 906438032Speter message. Currently, it just says "cannot send for 906538032Speter four hours". 906638032Speter Fix the "Original message received" time generated for 906738032Speter returntosender messages. It was previously listed as 906838032Speter the current time. Bug reported by Eric Hagberg of 906938032Speter Cornell University Medical College. 907038032Speter If there is an error when writing the body of a message, 907138032Speter don't send the trailing dot and wait for a response 907238032Speter in sender SMTP, as this could cause the connection to 907338032Speter hang up under some bizarre circumstances. From Eric 907438032Speter Wassenaar. 907538032Speter Fix some server SMTP synchronization problems caused when 907638032Speter connections fail during message collection. From 907738032Speter Eric Wassenaar. 907838032Speter Fix a problem that can cause srvrsmtp to reject mail if the 907938032Speter name server is down -- it accepts the RCPT but rejects 908038032Speter the DATA command. Problem reported by Jim Murray of 908138032Speter Stratus. 908238032Speter Fix a problem that can cause core dumps if the config file 908338032Speter incorrectly resolves to a null hostname. Reported by 908438032Speter Allan Johannesen of WPI. 908538032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 908638032Speter by non-root users were not put into 908738032Speter X-Authentication-Warning:s as intended because the 908838032Speter config file hadn't set the PrivacyOptions yet. Fix 908938032Speter from Sven-Ove Westberg of the University of Lulea. 909038032Speter Under very odd circumstances, the alias file rebuild code 909138032Speter could get confused as to whether a database was 909238032Speter open or not. 909338032Speter Check "vendor code" on the end of V lines -- this is 909438032Speter intended to provide a hook for vendor-specific 909538032Speter configuration syntax. (This is a "new feature", 909638032Speter but I've made an exception to my rule in a belief 909738032Speter that this is a highly exceptional case.) 909838032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 909938032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 910038032Speter (from Jon Forrest of UC Berkeley) 910138032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 910238032Speter 910338032Speter8.6.1/8.6 1993/10/08 910438032Speter Portability fixes for A/UX and Encore UMAX V. 910538032Speter Fix error message handling -- if you had a name server down 910638032Speter causing an error during parsing, that message was never 910738032Speter propagated to the queue file. 910838032Speter 910938032Speter8.6/8.6 1993/10/05 911038032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 911138032Speter conf.h (other systems have the same bug). 911238032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 911338032Speter getdtablesize() instead of sysconf(); a disturbingly 911438032Speter large number of systems defined _SC_OPEN_MAX in the 911538032Speter header files but don't have the syscall. 911638032Speter Another patch to really truly ignore MX records in getcanonname 911738032Speter if trymx == FALSE. 911838032Speter Fix problem that caused the "250 IAA25499 Message accepted for 911938032Speter delivery" message to be omitted if there was an error 912038032Speter in the header of the message (e.g., a bad Errors-To: 912138032Speter line). Pointed out by Michael Corrigan of UCSD. 912238032Speter Announce name of host we are chatting when we get errors; this 912338032Speter is an IDA-ism suggested by Christophe Wolfhugel. 912438032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 912538032Speter Australian Artificial Intelligence Institute), SCO Unix 912638032Speter (from Murray Kucherawy of Hookup Communication Corp.), 912738032Speter NeXT (from Vince DeMarco and myself), Linux (from 912838032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 912938032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 913038032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 913138032Speter Some changes to get around gcc optimizer bugs. From Takahiro 913238032Speter Kanbe. 913338032Speter Fix error recovery in queueup if another tf file of the same 913438032Speter name already exists. Problem stumbled over by Bill 913538032Speter Wisner of The Well. 913638032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 913738032Speter Problem noted by Keith McMillan of Ameritech Services. 913838032Speter Deal with group permissions properly when opening .forward and 913938032Speter :include: files. This relaxes the 8.1C restrictions 914038032Speter slightly more. This includes proper setting of groups 914138032Speter when reading :include: files, allowing you to read some 914238032Speter files that you should be able to read but have previously 914338032Speter been denied unless you owned them or they had "other" 914438032Speter read permission. 914538032Speter Make certain that $j is in $=w (after the .cf is read) so that 914638032Speter if the user is forced to override some silly system, 914738032Speter MX suppression will still work. 914838032Speter Fix a couple of efficiency problems where newstr was double- 914938032Speter calling expensive routines. In at least one case, it 915038032Speter wasn't guaranteed that they would always return the 915138032Speter same result. Problem noted by Christophe Wolfhugel. 915238032Speter Fix null pointer dereference in putoutmsg -- only on an error 915338032Speter condition from a non-SMTP mailer. From Motonori 915438032Speter Nakamura. 915538032Speter Macro expand "C" line class definitions before scanning so that 915638032Speter "CX $Z" works. 915738032Speter Fix problem that caused error message to be sent while still 915838032Speter trying to send the original message if the connection 915938032Speter is closed during a DATA command after getting an error 916038032Speter on an RCPT command (pretty obscure). Problem reported 916138032Speter by John Myers of CMU. 916238032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 916338032Speter term bug. 916438032Speter Fix a nasty bug causing core dumps when returning the "warning: 916538032Speter cannot deliver for N hours -- will keep trying" message; 916638032Speter it only occurred if you had PostmasterCopy set and 916738032Speter only on some architectures. Although sendmail would 916838032Speter keep trying, it would send error messages on each 916938032Speter queue interval. This is an important fix. 917038032Speter Allow u and g options to take user and group names respectively. 917138032Speter Don't do a chdir into the queue directory in -bt mode to make 917264562Sgshapiro ruleset testing a bit easier. 917338032Speter Don't allow users to turn off logging (using -oL) on the command 917438032Speter line -- command line can only raise, not lower, logging 917538032Speter level. 917638032Speter Set $u to the original recipient on the SMTP transaction or on 917738032Speter the command line. This is only done if there is exactly 917838032Speter one recipient. Technically, this does not meet the 917938032Speter specs, because it does not guarantee a domain on the 918038032Speter address. 918138032Speter Fix a problem that dumped error messages on bad addresses if 918238032Speter you used the -t flag. Problem noted by Josh Smith of 918338032Speter Harvey Mudd College. 918438032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 918538032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 918638032Speter avoid the problem of people who use angle brackets in 918738032Speter their full name information. 918838032Speter Fix a null pointer dereference if you set option "l", have 918938032Speter an Errors-To: header in the message, and have Errors-To: 919038032Speter defined in the config file H lines. From J.R. Oldroyd. 919138032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 919238032Speter wrong when compiling. Suggested by Rick McCarty of TI. 919338032Speter Fix a problem that could pass negative SIZE parameter if the 919438032Speter df file got lost; this would cause servers to always 919538032Speter give a temporary failure, making the problem even worse. 919638032Speter Problem noted by Allan Johannesen of WPI. 919738032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 919838032Speter protocol timeouts (30s default). Requested by Murray 919938032Speter Kucherawy of HookUp Communication Corp. to handle bogus 920038032Speter PC TCP/IP implementations. 920138032Speter Change $w default definition to be just the first component of 920238032Speter the domain name on config level 5. The $j macro defaults 920338032Speter to the FQDN; $m remains as before. This lets well-behaved 920438032Speter config files use any of the short, long, or subdomain 920538032Speter names. 920638032Speter Add makesendmail script in src to try to automate multi-architecture 920738032Speter builds. I know, this is sub-optimal, but it is still 920838032Speter helpful. 920938032Speter Fix very obscure race condition that can cause a queue run to 921038032Speter get a queue file for an already completed job. This 921138032Speter problem has existed for years. Problem noted by the 921238032Speter long suffering Allan Johannesen of WPI. 921338032Speter Fix a problem that caused the raw sender name to be passed to 921438032Speter udbsender instead of the canonified name -- this caused 921538032Speter it to sometimes miss records that it should have found. 921638032Speter Relax check of name on HELO packet so that a program using -bs 921738032Speter that claims to be itself works properly. 921838032Speter Restore rewriting of $: part of address through 2, R, 4 in 921938032Speter buildaddr -- this requires passing a lot of flags to get 922064562Sgshapiro it right. Unlike old versions, this ONLY rewrites 922138032Speter recipient addresses, not sender addresses. 922238032Speter Fix a bug that caused core dumps in config files that cannot 922338032Speter resolve /file/name style addresses. Fix from Jonathan 922438032Speter Kamens of OpenVision Technologies. 922538032Speter Fix problem with fcntl locking that can cause error returns to 922638032Speter be lost if the lock is lost; this required fully 922738032Speter queueing everything, dropping the envelope (so errors 922838032Speter would get returned), and then re-reading the queue from 922938032Speter scratch. 923038032Speter Fix a problem that caused aliases that redefine an otherwise 923138032Speter true address to still send to the original address 923238032Speter if and only if the alias failed in certain bizarre 923338032Speter ways (e.g, if they pointed at a list:; syntax address). 923438032Speter Problem pointed out by Jonathan Kamens. 923538032Speter Remove support for frozen configuration files. They caused 923638032Speter more trouble than it was worth. 923738032Speter Fix problem that can cause error messages to get ignored when 923838032Speter using both -odb and -t flags. Problem noted by Rob 923938032Speter McNicholas at U.C. Berkeley. 924038032Speter Include all "normal" variations on hostname in $=w. For example, 924138032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 924238032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 924338032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 924438032Speter the queue. 924538032Speter Reset SmtpPhase global on initial connection creation so that 924638032Speter messages don't come out with stale information. 924738032Speter Pass an "ext" argument to lockfile so that error/log messages 924838032Speter will properly reflect the true filename being locked. 924938032Speter Put all [...] address forms into $=w -- this eliminates the need 925038032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 925143730Speter Myers of CMU. 925238032Speter Fix a bug that can cause qf files to be left around even after 925338032Speter an SMTP RSET command. Problem and fix from Michael 925438032Speter Corrigan. 925538032Speter Don't send a PostmasterCopy to errors when the Precedence: is 925638032Speter negative. Error reports still go to the envelope 925738032Speter sender address. 925838032Speter Add LA_SHORT for load averages. 925938032Speter Lock sendmail.st file when posting statistics. 926038032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 926138032Speter set the size of the TCP send and receive buffers; if you 926238032Speter run over a slow slip line you may need to set these down 926338032Speter (although it would be better to fix the SLIP implementation 926438032Speter so that it's not necessary to recompile every program 926538032Speter that does bulk data transfer). 926664562Sgshapiro Allow null defaults on $( ... $) lookups. Problem reported by 926738032Speter Amir Plivatsky. 926838032Speter Diagnose crufty S and V config lines. This resulted from an 926938032Speter observation that some people were using the SITE macro 927038032Speter without the SITECONFIG macro first, which was causing 927138032Speter bogus config files that were not caught. 927264562Sgshapiro Fix makemap -f flag to turn off case folding (it was turning it 927338032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 927438032Speter Fix a problem that caused multiple error messages to be sent if 927538032Speter you used "sendmail -t -oem -odb", your system uses fcntl 927638032Speter locking, and one of the recipient addresses is unknown. 927738032Speter Reset uid earlier in include() so that recursive .forwards or 927838032Speter :include:s don't use the wrong uid. 927938032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 928038032Speter called, the code to recover the descriptor was broken. 928138032Speter This sometimes (only sometimes) caused problems with the 928238032Speter alias file. Fix from Motonori Nakamura. 928338032Speter Fix a problem that caused aliaswait to go into infinite recursion 928438032Speter if the @:@ metasymbol wasn't found in the alias file. 928538032Speter Improve error message on newaliases if database files cannot be 928638032Speter opened or if running with no database format defined. 928738032Speter Do a better estimation of the size of error messages when NoReturn 928838032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 928938032Speter Fix a problem causing the "c" option (don't connect to expensive 929038032Speter mailers) to be ignored in SMTP. Problem noted and the 929138032Speter solution suggested by Robert Elz of The University of 929238032Speter Melbourne. 929338032Speter Improve connection caching algorithm by passing "[host]" to 929438032Speter hostsignature, which strips the square brackets and 929538032Speter returns the real name. This allows mailertable entries 929638032Speter to match regular entries. 929738032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 929838032Speter feature, even if it doesn't work right. 929938032Speter Catch and log attempts to try the "wiz" command in server SMTP. 930038032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 930138032Speter Be more generous at assigning $z to the home directory -- do this 930238032Speter for programs that are specified through a .forward file. 930338032Speter Fix from Andrew Chang of Sun Microsystems. 930438032Speter Always save a fatal error message in preference to a non-fatal 930538032Speter error message so that the "subject" line of return 930638032Speter messages is the best possible. 930738032Speter CONFIG: reduce the number of quotes needed to quote configuration 930838032Speter parameters with commas: two quotes should work now, e.g., 930938032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 931038032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 931138032Speter connections (domain-ized UUCP). 931238032Speter CONFIG: fix bug in default maps (-o must be before database file 931338032Speter name). Pointed out by Christophe Wolfhugel. 931438032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 931538032Speter DNS. This would presumably be used in UUCP islands. 931638032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 931738032Speter CONFIG: log $u in Received: line. This is in technical violation 931838032Speter of the standards, since it doesn't guarantee a domain 931938032Speter on the address. 932038032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 932138032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 932238032Speter the "m" flag should you want it. Apparently some Solaris 2.2 932338032Speter installations can't handle multiple local recipients. 932438032Speter Problem noted by Josh Smith. 932538032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 932638032Speter CONFIG: change default version level from 4 to 5. 932738032Speter CONFIG: add FEATURE(nullclient) to create a config file that 932838032Speter forwards all mail to a hub without ever looking at the 932943730Speter addresses in any detail. 933038032Speter CONFIG: properly strip mailer: information off of relays when 933138032Speter used to change .BITNET form into %-hack form. 933238032Speter CONFIG: fix a problem that caused infinite loops if presented 933338032Speter with an address such as "!foo". 933438032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 933538032Speter the reverse "PTR" mapping is broken. There's a better 933638032Speter way to do this, but the change is fairly major and I 933738032Speter want to hold it for another release. Problem noted by 933838032Speter Bret Marquis. 933938032Speter 934038032Speter8.5/8.5 1993/07/23 934138032Speter Serious bug: if you used a command line recipient that was unknown 934238032Speter sendmail would not send a return message (it was treating 934338032Speter everything as though it had an SMTP-style client that 934438032Speter would do the return itself). Problem noted by Josh Smith. 934538032Speter Change "trymx" option in getcanonname() to ignore all MX data, 934638032Speter even during a T_ANY query. This actually didn't break 934738032Speter anything, because the only time you called getcanonname 934838032Speter with !trymx was if you already knew there were no MX 934938032Speter records, but it is somewhat cleaner. From Motonori 935038032Speter Nakamura. 935138032Speter Don't call getcanonname from getmxrr if you already know there 935238032Speter are no DNS records matching the name. 935338032Speter Fix a problem causing error messages to always include "The 935438032Speter original message was received ... from localhost". 935538032Speter The correct original host information is now included. 935638032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 935738032Speter version of "test" doesn't have the -x flag). Change it 935838032Speter to use -f instead. From John Myers. 935938032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 936038032Speter esmtp -- it should be smtp. 936138032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 936238032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 936338032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 936438032Speter this cleans up the configs somewhat. This fixes a serious 936538032Speter problem that caused route-addrs to get mistaken as relays, 936638032Speter pointed out by John Myers. WARNING: this also causes 936738032Speter the default on SMART_HOST to change from "suucp" to 936838032Speter "relay" if you have MAILER(smtp) specified. 936938032Speter 937038032Speter8.4/8.4 1993/07/22 937138032Speter Add option `w'. If you receive a message that comes to you because 937238032Speter you are the best (lowest preference) target of an MX, and 937338032Speter you haven't explicitly recognized the source MX host in 937438032Speter your .cf file, this option will cause you to try the target 937538032Speter host directly (as if there were no MX for it at all). If 937638032Speter `w' is not set, this case is a configuration error. 937738032Speter Beware: if `w' is set, senders may get bogus errors like 937838032Speter "message timed out" or "host unknown" for problems that 937938032Speter are really configuration errors. This option is 938038032Speter disrecommended, provided only for compatibility with 938138032Speter UIUC sendmail. 938238032Speter Fix a problem that caused the incoming socket to be left open 938338032Speter when sendmail forks after the DATA command. This caused 938438032Speter calling systems to wait in FIN_WAIT_2 state until the 938538032Speter entire list was processed and the child closed -- a 938638032Speter potentially prodigious amount of time. Problem noted 938738032Speter by Neil Rickert. 938838032Speter Fix problem (created in 6.64) that caused mail sent to multiple 938938032Speter addresses, one of which was a bad address, to completely 939038032Speter suppress the sending of the message. This changes 939138032Speter handling of EF_FATALERRS somewhat, and adds an 939238032Speter EF_GLOBALERRS flag. This also fixes a potential problem 939338032Speter with duplicate error messages if there is a syntax error 939438032Speter in the header of a message that isn't noticed until late 939538032Speter in processing. Original problem pointed out by Josh Smith 939638032Speter of Harvey Mudd College. This release includes quite a bit 939738032Speter of dickering with error handling (see below). 939838032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 939938032Speter will only hurt already-broken software and should help 940038032Speter humans. 940138032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 940238032Speter compiled in. It would never read the alias file. 940338032Speter Repair unbalanced `)' and `>' (the "open" versions are already 940438032Speter repaired). 940538032Speter Logging of "done" in dropenvelope() was incorrect: it would 940638032Speter log this even when the queue file still existed. Change 940738032Speter this to only log "done" (at log level 11) when the 940838032Speter queue file is actually removed. From John Myers. 940938032Speter Log "lost connection" in server SMTP at log level 20 if there 941038032Speter is no pending transaction. Some senders just close the 941138032Speter connection rather than sending QUIT. 941238032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 941338032Speter domains that do not have MX records -- this would cause 941438032Speter the subsequent host name lookup to fail. The problem 941538032Speter only occurred if you had FEATURE(nocanonify) set. 941638032Speter Problem noted by Rick McCarty of Texas Instruments. 941738032Speter Fix invocation of setvbuf when passed a -X flag -- I had 941843730Speter unwittingly used an ANSI C extension, and this caused 941938032Speter core dumps on some machines. 942038032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 942138032Speter Previously it just gave an empty send queue, which 942238032Speter then gave either "Need RCPT (recipient)" at the DATA 942338032Speter (confusing, since you had given an RCPT command which 942438032Speter returned 250) or just dropped the email, depending on 942538032Speter whether you were running VERBose mode. Now it usually 942638032Speter diagnoses this case as "aliasing/forwarding loop broken". 942738032Speter Unfortunately, it still doesn't adequately diagnose 942838032Speter some true error conditions. 942938032Speter Add internal concept of "warning messages" using 6xx codes. 943038032Speter These are not reported only to Postmaster. Unbalanced 943138032Speter parens, brackets, and quotes are printed as 653 codes. 943238032Speter They are always mapped to 5xx codes before use in SMTP. 943338032Speter Clean up error messages to tell both the actual address that 943438032Speter failed and the alias they arose from. This makes it 943538032Speter somewhat easier to diagnose problems. Difficulty noted 943638032Speter by Motonori Nakamura. 943738032Speter Fix a problem that inappropriately added a ctladdr to addresses 943838032Speter that shouldn't have had one during a queue run. This 943938032Speter caused error messages to be handled differently during 944038032Speter a queue run than a direct run. 944138032Speter Don't print the qf name and line number if you get errors during 944238032Speter the direct run of the queue from srvrsmtp -- this was 944338032Speter just extra stuff for users to crawl through. 944438032Speter Put command line flags on second line of pid file so you can 944538032Speter auto-restart the daemon with all appropriate arguments. 944638032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 944738032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 944838032Speter restart it. 944938032Speter Remove the ``setuid(getuid())'' in main -- this caused the 945038032Speter IDENT daemon to screw up. This required that I change 945138032Speter HASSETEUID to HASSETREUID and complicate the mode 945238032Speter changing somewhat because both Ultrix and SunOS seem 945338032Speter to have a bug causing seteuid() to set the saved uid 945438032Speter as well as the effective. The program test/t_setreuid.c 945538032Speter will test to see if your implementation of setreuid(2) 945638032Speter is appropriately functional. 945738032Speter The FallBackMX (option V) handling failed to properly identify 945838032Speter fallback to yourself -- most of the code was there, 945938032Speter but it wasn't being enabled. Problem noted by Murray 946038032Speter Kucherawy of the University of Waterloo. 946138032Speter Change :include: open timeout from ETIMEDOUT to an internal 946238032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 946338032Speter with CurHostName" in error messages, which can be 946438032Speter confusing. Reported by Jonathan Kamens of OpenVision 946538032Speter Technologies. 946638032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 946738032Speter process group id. The original fix was to get around 946838032Speter some problems with recalcitrant MUAs, but it breaks 946938032Speter any call from a shell that creates a process group id 947038032Speter different from the process id. I could try to fix 947138032Speter this by diddling the tty owner (using tcsetpgrp or 947238032Speter equivalent) but this is too likely to break other 947338032Speter things. 947438032Speter Portability changes: 947538032Speter Support -M as equivalent to -oM on Ultrix -- apparently 947664562Sgshapiro DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 947738032Speter instead of using standard flags. Oh joy. This 947838032Speter behavior reported by Jon Giltner of University 947938032Speter of Colorado. 948038032Speter SGI IRIX -- this includes several changes that should 948138032Speter help other strict ANSI compilers. 948238032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 948338032Speter Corporation. 948438032Speter Solaris running the Sun C compiler (which despite the 948538032Speter documentation apparently doesn't define 948638032Speter __STDC__ by default). 948738032Speter ConvexOS from Eric Schnoebelen of Convex. 948838032Speter Sony NEWS workstations and Omron LUNA workstations from 948938032Speter Motonori Nakamura. 949038032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 949138032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 949238032Speter several people have made a good argument that this 949338032Speter creates more problems than it solves (although this 949438032Speter may prove painful in the short run). 949538032Speter CONFIG: generalize all the relays to accept a "mailer:host" 949638032Speter format. 949738032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 949838032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 949938032Speter addresses are also passed through this ruleset. 950038032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 950138032Speter internet-style addresses would "fall off the end" of 950238032Speter ruleset zero and be interpreted as local -- however, 950364562Sgshapiro the angle brackets confused the recursive call. 950438032Speter These are now diagnosed as "Unrecognized host name". 950538032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 950638032Speter ifdef(`_MAILER_USENET_') instead of 950738032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 950838032Speter of SINTEF RUNIT, Oslo. 950938032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 951038032Speter early in ruleset 0; this allows .mc authors to bypass 951138032Speter things like the "short circuit" code for local addresses. 951238032Speter Prompted by a comment by Bill Wisner of The Well. 951338032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 951438032Speter esmtp) to send SMTP mail. This allows you to default 951538032Speter to esmtp but use a mailertable or other override to 951638032Speter deal with broken servers. This logic was pointed out 951738032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 951838032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 951938032Speter environments. Ugly as sin. 952038032Speter 952138032Speter8.3/8.3 1993/07/13 952238032Speter Fix setuid problems introduced in 8.2 that caused messages 952338032Speter like "Cannot create qfXXXXXX: Invalid argument" 952438032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 952538032Speter involved a new compile flag "HASSETEUID" that takes 952638032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 952738032Speter that the POSIX interface is broken enough to break 952838032Speter some systems badly. This includes some fixes for 952938032Speter HP-UX. Also fixes problems where the real uid is 953038032Speter not reset properly on startup (from Neil Rickert). 953138032Speter Fix a problem that caused timed out messages to not report the 953238032Speter addresses that timed out. Error messages are also more 953364562Sgshapiro "user friendly". 953438032Speter Drop required bandwidth on connections from 64 bytes/sec to 953538032Speter 16 bytes/sec. 953638032Speter Further Solaris portability changes -- doesn't require the BSD 953738032Speter compatibility library. This also adds a new 953838032Speter "HASGETDTABLESIZE" compile flag which can be used if 953938032Speter you want to use getdtablesize(2) instead of sysconf(2). 954038032Speter These are loosely based on changes from David Meyer at 954138032Speter University of Oregon. This now seems to work, at least 954238032Speter for quick test cases. 954338032Speter Fix a problem that can cause duplicate error messages to be 954438032Speter sent if you are in SMTP, you send to multiple addresses, 954538032Speter and at least one of those addresses is good and points 954638032Speter to an account that has a .forward file (whew!). 954738032Speter Fix a problem causing messages to be discarded if checkcompat() 954838032Speter returned EX_TEMPFAIL (because it didn't properly mark 954938032Speter the "to" address). Problem noted by John Myers. 955038032Speter Fix dfopen to return NULL if the open failed; I was depending 955138032Speter on fdopen(-1) returning NULL, which isn't the case. This 955238032Speter isn't serious, but does result in weird error diagnoses. 955338032Speter From Michael Corrigan. 955438032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 955538032Speter messages sent through UUCP-family mailers. Suggested 955638032Speter by Bill Wisner of The Well. 955738032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 955838032Speter include a "uucp-dom" mailer that uses domain-style 955938032Speter addressing. Suggested by Bill Wisner. 956038032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 956138032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 956238032Speter Christophe Wolfhugel. 956338032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 956438032Speter 956538032Speter8.2/8.2 1993/07/11 956638032Speter Don't drop out on config file parse errors in -bt mode. 956738032Speter On older configuration files, assume option "l" (use Errors-To 956838032Speter header) for back compatibility. NOTE: this DOES NOT 956938032Speter imply an endorsement of the Errors-To: header in any way. 957038032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 957138032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 957238032Speter SMTP server to give an error on this command, and 957338032Speter logging it in the transcript can be confusing. Fix 957438032Speter from Bill Wisner. 957538032Speter IRIX compatibility changes provided by Dan Rich 957638032Speter <drich@sandman.lerc.nasa.gov>. 957738032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 957838032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 957938032Speter <juo@klinzhai.rutgers.edu> 958038032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 958138032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 958238032Speter match the other flags in that file. 958338032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 958438032Speter Save h_errno in mci struct and improve error message display. 958538032Speter Changes from Eric Wassenaar. 958638032Speter Open /dev/null for the transcript if the create of the xf file 958738032Speter failed; this avoids at least one possible null pointer 958838032Speter reference in very weird cases. From Eric Wassenaar. 958938032Speter Clean up statistics gathering; it was over-reporting because of 959038032Speter forks. From Eric Wassenaar. 959138032Speter Fix problem that causes old Return-Path: line to override new 959238032Speter Return-Path: line (conf.c needs H_FORCE to avoid 959338032Speter re-using old value). From Motonori Nakamura. 959438032Speter Fix broken -m flag in K definition -- even if -m (match only) 959538032Speter was specified, it would still replace the key with the 959638032Speter value. Noted by Rick McCarty of Texas Instruments. 959738032Speter If the name server timed out over several days, no "timed out" 959838032Speter message would ever be sent back. The timeout code 959938032Speter has been moved from markfailure() to dropenvelope() 960038032Speter so that all such failures should be diagnosed. Pointed 960138032Speter out by Christophe Wolfhugel and others. 960238032Speter Relax safefile() constraints: directories in an include or 960338032Speter forward path must be readable by self if the controlling 960438032Speter user owns the entry, readable by all otherwise (e.g., 960538032Speter when reading your .forward file, you have to own and 960638032Speter have X permission in it; everyone needs X permission in 960738032Speter the root and directories leading up to your home); 960838032Speter include files must be readable by anyone, but need not 960938032Speter be owned by you. 961038032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 961138032Speter reading a .forward file; this gets around some problems 961238032Speter on NFS mounts if root permission is not exported and 961338032Speter the user's home directory isn't x'able. 961438032Speter Additional NeXT portability enhancements from Axel Zinser. 961538032Speter Additional HP-UX portability enhancements from Brian Bullen. 961638032Speter Add a timeout around SMTP message writes; this assumes you can 961738032Speter get throughput of at least 64 bytes/second. Note that 961838032Speter this does not impact the "datafinal" default, which 961938032Speter is separate; this is just intended to work around 962038032Speter network clogs that will occur before the final dot 962138032Speter is sent. From Eric Wassenaar. 962238032Speter Change map code to set the "include null" flag adaptively -- 962338032Speter it initially tries both, but if it finds anything 962438032Speter matching without a null it never tries again with a 962538032Speter null and vice versa. If -N is specified, it never 962638032Speter tries without the null and creates new maps with a 962738032Speter null byte. If -O is specified, it never tries with 962838032Speter the null (for efficiency). If -N and -O are specified, 962938032Speter you get -NO (get it?) lookup at all, so this would 963038032Speter be a bad idea. If you don't specify either -N or -O, 963138032Speter it adapts. 963238032Speter Fix recognition of "same from address" so that MH submissions 963338032Speter will insert the appropriate full name information; 963438032Speter this used to work and got broken somewhere along the 963538032Speter way. 963638032Speter Some changes to eliminate some unnecessary SYSERRs in the 963738032Speter log. For example, if you lost a connection, don't 963838032Speter bother reporting that fact on the connection you lost. 963938032Speter Add some "extended debugging" flags to try to track down 964038032Speter why we get occasional problems with file descriptor 964143730Speter one being closed when execing a mailer; it seems to 964238032Speter only happen when there has been another error in the 964338032Speter same transaction. This requires XDEBUG, defined 964438032Speter by default in conf.h. 964538032Speter Add "-X filename" command line flag, which logs both sides of 964638032Speter all SMTP transactions. This is intended ONLY for 964738032Speter debugging bad implementations of other mailers; start 964838032Speter it up, send a message from a mailer that is failing, 964938032Speter and then kill it off and examine the indicated log. 965038032Speter This output is not intended to be particularly human 965138032Speter readable. This also adds the HASSETVBUF compile 965238032Speter flag, defaulted on if your compiler defines __STDC__. 965338032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 965438032Speter have a local net that should get direct connects, you 965538032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 965638032Speter See cf/README for an example. 965738032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 965838032Speter sites that don't use the -d flag. 965938032Speter CONFIG: hide recipient addresses as well as sender addresses 966038032Speter behind $M if FEATURE(allmasquerade) is specified; this 966138032Speter has been requested by several people, but can break 966238032Speter local aliases. For example, if you mail to "localalias" 966338032Speter this will be rewritten as "localalias@masqueradehost"; 966438032Speter although initial delivery will work, replies will be 966538032Speter broken. Use it sparingly. 966638032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 966738032Speter to qualified domains in headers. I believe this is 966838032Speter largely equivalent to the IDA feature of the same name. 966938032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 967038032Speter to override the "system name" as your UUCP name -- 967138032Speter in particular, to use domain-ized UUCP names. From 967238032Speter Bill Wisner of The Well. 967338032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 967438032Speter first. This is currently unused in the config files, 967538032Speter but could be used in a mailertable entry. 967638032Speter 967738032Speter8.1C/8.1B 1993/06/27 967838032Speter Serious security bug fix: it was possible to read any file on 967938032Speter the system, regardless of ownership and permissions. 968038032Speter If a subroutine returns a fully qualified address, return it 968138032Speter immediately instead of feeding it back into rewriting. 968238032Speter This fixes a problem with mailertable lookups. 968338032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 968464562Sgshapiro 968538032Speter8.1B/8.1A 1993/06/12 968638032Speter Serious bug fix: pattern matching backup algorithm stepped by 968738032Speter two tokens in classes instead of one.
