Problem noted by Michael Sims. 14147078Sgshapiro Deal with empty hostnames in hostsignature(). This bug could lead 15147078Sgshapiro to an endless loop when doing LMTP deliveries to another 16147078Sgshapiro host. Problem first reported by Martin Lathoud and 17147078Sgshapiro tracked down by Gael Roualland. 18147078Sgshapiro Make sure return parameters are initialized in getmxrr(). Problem 19147078Sgshapiro found by Gael Roualland using valgrind. 20147078Sgshapiro If shared memory is used and the RunAsUser option is set, then the 21147078Sgshapiro owner and group of the shared memory segment is set to 22147078Sgshapiro the ids specified RunAsUser and the access mode is set 23147078Sgshapiro to 0660 to allow for updates by sendmail processes. 24147078Sgshapiro The number of queue entries that is (optionally) kept in shared 25147078Sgshapiro memory was wrong in some cases, e.g., envelope splitting 26147078Sgshapiro and bounce generation. 27147078Sgshapiro Undo a change made in 8.13.0 to silently truncate long strings 28147078Sgshapiro in address rewriting because the message can be triggered 29147078Sgshapiro for header checks where long strings are legitimate. 30147078Sgshapiro Problem reported by Mary Verge DeSisto, and tracked 31147078Sgshapiro down with the help of John Beck of Sun Microsystems. 32147078Sgshapiro The internal stab map did not obey the -m flag. Patch from 33147078Sgshapiro Rob McMahon of Warwick University, England. 34147078Sgshapiro The socket map did not obey the -f flag. Problem noted by 35147078Sgshapiro Dan Ringdahl, forwarded by Andrzej Filip. 36147078Sgshapiro The addition of LDAP recursion in 8.13.0 broke enforcement of 37147078Sgshapiro the LDAP map -1 argument which tells the MTA to only 38147078Sgshapiro return success if and only if a single LDAP match is found. 39147078Sgshapiro Add additional error checks in the MTA for milter communication 40147078Sgshapiro to avoid a possible segmentation fault. Based on patch 41147078Sgshapiro by Joe Maimon. 42147078Sgshapiro Do not trigger an assertion if X509_digest() returns success but 43147078Sgshapiro does not assign a value to its output parameter. Based 44147078Sgshapiro on patch by Brian Kantor. 45147078Sgshapiro Add more checks when resetting internal AUTH data (applies only 46147078Sgshapiro to Cyrus SASL version 2). Otherwise an SMTP session might 47147078Sgshapiro be dropped after an AUTH failure. 48147078Sgshapiro Portability: 49147078Sgshapiro Add LA_LONGLONG as valid LA_TYPE type for systems that use 50147078Sgshapiro "long long" to read load average data, e.g., 51147078Sgshapiro AIX 5.1 in 32 bit mode. Note: this has to be set 52147078Sgshapiro "by hand", it is not (yet) automatically detected. 53147078Sgshapiro Problem noted by Burak Bilen. 54147078Sgshapiro Use socklen_t for accept(), etc. on AIX 5.x. This should 55147078Sgshapiro fix problems when compiling in 64 bit mode. 56147078Sgshapiro Problem first reported by Harry Meiert of 57147078Sgshapiro University of Bremen. 58147078Sgshapiro New Files: 59147078Sgshapiro include/sm/sem.h 60147078Sgshapiro libsm/sem.c 61147078Sgshapiro libsm/t-sem.c 62147078Sgshapiro 63141858Sgshapiro8.13.3/8.13.3 2005/01/11 64141858Sgshapiro Enhance handling of I/O errors, especially EOF, when STARTTLS 65141858Sgshapiro is active. 66141858Sgshapiro Make sure a connection is not reused after it has been closed 67141858Sgshapiro due to a 421 error. Problem found by Allan E Johannesen 68141858Sgshapiro of Worcester Polytechnic Institute. 69141858Sgshapiro Avoid triggering an assertion when sendmail is interrupted while 70141858Sgshapiro closing a connection. Problem found by Allan E Johannesen 71141858Sgshapiro of Worcester Polytechnic Institute. 72141858Sgshapiro Regression: a change in 8.13.2 caused sendmail not to try the 73141858Sgshapiro next MX host (or FallbackMXhost if configured) when, at 74141858Sgshapiro connection open, the current server returns a 4xy or 5xy 75141858Sgshapiro SMTP reply code. Problem noted by Mark Tranchant. 76141858Sgshapiro 77141858Sgshapiro8.13.2/8.13.2 2004/12/15 78141858Sgshapiro Do not split the first header even if it exceeds the internal 79141858Sgshapiro buffer size. Previously a part of such a header would 80141858Sgshapiro end up in the body of the message. Problem noted by 81141858Sgshapiro Simple Nomad of BindView. 82141858Sgshapiro Do not complain about "cataddr: string too long" when checking 83141858Sgshapiro headers that do not contain RFC 2822 addresses. 84141858Sgshapiro Problem noted by Rich Graves of Brandeis University. 85141858Sgshapiro If a server returns a 421 reply to the RSET command between 86141858Sgshapiro message deliveries, do not attempt to deliver any more 87141858Sgshapiro messages on that connection. This prevents bogus "Bad 88141858Sgshapiro file number" recipient status. Problem noted by 89141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 90141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 91141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 92141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 93141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 94141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 95141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 96141858Sgshapiro them off at a comma. Problem noted by Krzysztof Oledzki. 97141858Sgshapiro Add more logging to milter change header functions to 98141858Sgshapiro complement existing logging. Based on patch from 99141858Sgshapiro Gurusamy Sarathy of Active State. 100141858Sgshapiro Include <lber.h> in include/sm/config.h when LDAPMAP is defined. 101141858Sgshapiro Patch from Edgar Hoch of the University of Stuttgart. 102141858Sgshapiro Fix DNS lookup if IPv6 is enabled when converting an IP address 103141858Sgshapiro to a hostname for use with SASL. Problem noted by Ken Jones; 104141858Sgshapiro patch from Hajimu UMEMOTO. 105141858Sgshapiro CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog 106141858Sgshapiro mailer. Patch from John Beck of Sun Microsystems. 107141858Sgshapiro LIBMILTER: It was possible that xxfi_abort() was called after 108141858Sgshapiro xxfi_eom() for a message if some timeouts were triggered. 109141858Sgshapiro Patch from Alexey Kravchuk. 110141858Sgshapiro LIBMILTER: Slightly rearrange mutex use in listener.c to allow 111141858Sgshapiro different threads to call smfi_opensocket() and smfi_main(). 112141858Sgshapiro Patch from Jordan Ritter of Cloudmark. 113141858Sgshapiro MAIL.LOCAL: Properly terminate MBDB before exiting. Problem 114141858Sgshapiro noted by Nelson Fung. 115141858Sgshapiro MAIL.LOCAL: make strip-mail.local used a wrong path to access 116141858Sgshapiro mail.local. Problem noted by William Park. 117141858Sgshapiro VACATION: Properly terminate MBDB before exiting. Problem noted 118141858Sgshapiro by Nelson Fung. 119141858Sgshapiro Portability: 120141858Sgshapiro Add support for DragonFly BSD. 121141858Sgshapiro New Files: 122141858Sgshapiro cf/ostype/dragonfly.m4 123141858Sgshapiro devtools/OS/DragonFly 124141858Sgshapiro include/sm/os/sm_os_dragonfly.h 125141858Sgshapiro Deleted Files: 126141858Sgshapiro libsm/vsscanf.c 127141858Sgshapiro 128132943Sgshapiro8.13.1/8.13.1 2004/07/30 129132943Sgshapiro Using the default AliasFile ldap: specification would cause the 130132943Sgshapiro objectClasses of the LDAP response to be included in the 131132943Sgshapiro alias expansion. Problem noted by Brenden Conte of 132132943Sgshapiro Rensselaer Polytechnic Institute. 133132943Sgshapiro Fix support for a fallback smart host for system where DNS is 134132943Sgshapiro (partially) available. From John Beck of Sun Microsystems. 135132943Sgshapiro Fix SuperSafe=PostMilter behavior when a milter replaces a body 136132943Sgshapiro but the data file is not yet stored on disk because it is 137132943Sgshapiro smaller than the size of the memory buffer. Problem noted 138132943Sgshapiro by David Russell. 139132943Sgshapiro Fix certificate revocation list support; if a CRL was specified 140132943Sgshapiro but the other side presented a cert that was signed by 141132943Sgshapiro a different (trusted) CA than the one which issued the CRL, 142132943Sgshapiro verification would always fail. Problem noted by Al Smith. 143132943Sgshapiro Run mailer programs as the RunAsUser when RunAsUser is set and 144132943Sgshapiro the F=S mailer flag is set without a U= mailer equate. 145132943Sgshapiro Problem noted by John Gardiner Myers of Proofpoint. 146132943Sgshapiro ${nbadrcpts} was off by one if BadRcptThrottle is zero. 147132943Sgshapiro Patch from Sung-hoon Choi of DreamWiz Inc. 148132943Sgshapiro CONFIG: Emit a warning if FEATURE(`access_db') is used after 149132943Sgshapiro FEATURE(`greet_pause') because then the latter will not 150132943Sgshapiro use the access map. Note: if no default value is given 151132943Sgshapiro for FEATURE(`greet_pause') then it issues an error if 152132943Sgshapiro FEATURE(`access_db') is not specified before it. 153132943Sgshapiro Problem noted by Alexander Dalloz of University of 154132943Sgshapiro Bielefeld. 155132943Sgshapiro CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause') 156132943Sgshapiro is used to give more flexibility for local changes. 157132943Sgshapiro Portability: 158132943Sgshapiro Fix a 64 bit problem in the socket map code. Problem 159132943Sgshapiro noted by Geoff Adams. 160132943Sgshapiro NetBSD 2.0F has closefrom(3). Patch from Andrew Brown. 161132943Sgshapiro NetBSD can use sysctl(3) to get the number of CPUs in 162132943Sgshapiro a system. Patch from Andrew Brown. 163132943Sgshapiro Add a README file in doc/op/ to explain potential 164132943Sgshapiro incompatibilities with various *roff related 165132943Sgshapiro tools. Problem tracked down by Per Hedeland. 166132943Sgshapiro New Files: 167132943Sgshapiro doc/op/README 168132943Sgshapiro 169132943Sgshapiro8.13.0/8.13.0 2004/06/20 170132943Sgshapiro Do not include AUTH data in a bounce to avoid leaking confidential 171132943Sgshapiro information. See also cf/README about MSP and the section 172132943Sgshapiro "Providing SMTP AUTH Data when sendmail acts as Client". 173132943Sgshapiro Problem noted by Neil Rickert of Northern Illinois 174132943Sgshapiro University. 175132943Sgshapiro Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n 176132943Sgshapiro and -DSM_CONF_SETITIMER=0. Problem noted by Juergen Georgi 177132943Sgshapiro of RUS University of Stuttgart. 178132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 179132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 180132943Sgshapiro Add support for LDAP recursion based on types given to attribute 181132943Sgshapiro specifications in an LDAP map definition. This allows 182132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 183132943Sgshapiro URL which will in turn be queried. See the ``LDAP 184132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 185132943Sgshapiro Based on patch from Andrew Baucom. 186132943Sgshapiro Extend the default LDAP specifications for AliasFile 187132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 188132943Sgshapiro include support for LDAP recursion via new attributes. 189132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 190132943Sgshapiro of cf/README for more information. 191132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 192132943Sgshapiro LDAP API/protocol version to use. The default depends on 193132943Sgshapiro the LDAP library. 194132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 195132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 196132943Sgshapiro and -p port. This also allows for the use of LDAP over 197132943Sgshapiro SSL and connections via named sockets if your LDAP 198132943Sgshapiro library supports it. 199132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 200132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 201132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 202132943Sgshapiro during a SMTP session then terminate it just like it is 203132943Sgshapiro done for too many bad SMTP commands. 204132943Sgshapiro Basic connection rate control support has been added: the daemon 205132943Sgshapiro maintains the number of incoming connections per client 206132943Sgshapiro IP address and total in the macros {client_rate} and 207132943Sgshapiro {total_rate}, respectively. These macros can be used 208132943Sgshapiro in the cf file to impose connection rate limits. 209132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 210132943Sgshapiro determines the length of the interval for which the 211132943Sgshapiro number of connections is stored. Based on patch from 212132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 213132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 214132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 215132943Sgshapiro If enabled by the new ruleset greet_pause (see 216132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 217132943Sgshapiro amount of time before sending the initial 220 SMTP 218132943Sgshapiro greeting. If any traffic is received before then, a 554 219132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 220132943Sgshapiro during that connection. 221132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 222132943Sgshapiro server could sleep for a very long time. Fix based on 223132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 224132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 225132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 226132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 227132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 228132943Sgshapiro misinterpret it as a permanent error. 229132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 230132943Sgshapiro all milters accepted the mail. This can increase 231132943Sgshapiro performance if many mails are rejected by milters due to 232132943Sgshapiro body scans. Based on patch from David F. Skoll. 233132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 234132943Sgshapiro header, whether provided by the client or generated by 235132943Sgshapiro sendmail. 236132943Sgshapiro New macro {client_connections} which contains the number of open 237132943Sgshapiro connections in the SMTP server for the client IP address. 238132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 239132943Sgshapiro Mines de Paris. 240132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 241132943Sgshapiro to prevent confusion caused by running sendmail stop 242132943Sgshapiro scripts two or more times, where the second and subsequent 243141858Sgshapiro runs would report misleading error messages about sendmail's 244132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 245132943Sgshapiro for a discussion of the implications of this, including 246132943Sgshapiro how to correct broken scripts which may have depended on 247132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 248132943Sgshapiro Support per-daemon input filter lists which override the default 249132943Sgshapiro filter list specified in InputMailFilters. The filters 250132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 251132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 252132943Sgshapiro your configuration relies on this behavior, you have to 253132943Sgshapiro add those names to class 'w' yourself. Problem noted 254132943Sgshapiro by Sander Eerkes. 255132943Sgshapiro Support message quarantining in the mail queue. Quarantined 256132943Sgshapiro messages are not run on normal queue displays or runs 257132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 258132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 259132943Sgshapiro The -q command line option now can specify which queue to display 260132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 261132943Sgshapiro operates on lost queue items. 262132943Sgshapiro Restricted mail queue runs and displays can be done based on the 263132943Sgshapiro quarantined reason using -qQtext to run or display 264132943Sgshapiro quarantined items if the quarantine reason contains the 265132943Sgshapiro given text. Similarly, -q!Qtext will run or display 266132943Sgshapiro quarantined items which do not have the given text in the 267132943Sgshapiro quarantine reason. 268132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 269132943Sgshapiro new -Q option. See doc/op/op.me for more information. 270132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 271132943Sgshapiro quarantine reason is shown in a new line prefixed by 272132943Sgshapiro "QUARANTINE:". 273132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 274132943Sgshapiro to quarantine messages in check_* (except check_compat) and 275132943Sgshapiro header check rulesets. The $: of the mailer triplet will 276132943Sgshapiro be used for the quarantine reason. 277132943Sgshapiro Add a new quarantine count to the mailstats collected. 278132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 279132943Sgshapiro message if it is quarantined. 280132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 281132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 282132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 283132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 284132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 285132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 286132943Sgshapiro lookup for the client IP address. Note: this is the same 287132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 288132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 289132943Sgshapiro recipients received so far in a transaction. 290132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 291132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 292132943Sgshapiro noted by Kai Schlichting. 293132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 294132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 295132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 296132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 297132943Sgshapiro Wolfhugel of France Telecom Oleane. 298132943Sgshapiro Do not silently truncate long strings in address rewriting. 299132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 300132943Sgshapiro Oceana Matrix Ltd. 301132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 302132943Sgshapiro support mutual authentication. From Kenneth Murchison of 303132943Sgshapiro Oceana Matrix Ltd. 304132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 305132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 306132943Sgshapiro format just like the STARTTLS related macros to avoid 307132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 308132943Sgshapiro Masarati of SysNet s.n.c. 309132943Sgshapiro New option AuthRealm to set the authentication realm that is 310132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 311132943Sgshapiro of the University of Manitoba. 312132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 313132943Sgshapiro successful, otherwise relaying would be allowed if 314132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 315132943Sgshapiro is active. 316132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 317132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 318132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 319132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 320132943Sgshapiro DIGEST-MD5 and LOGIN. 321132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 322132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 323132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 324132943Sgshapiro overwrite each other's pid files. 325132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 326132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 327132943Sgshapiro Wolfhugel of France Telecom. 328132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 329132943Sgshapiro LogLevel 12 or higher. 330132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 331132943Sgshapiro try to use the SMTP command VERB to propagate this option 332132943Sgshapiro to the MTA which in turn will show the delivery just like 333132943Sgshapiro it was done before the default 8.12 separation of MSP and 334132943Sgshapiro MTA. Based on patch by Per Hedeland. 335132943Sgshapiro If a daemon is refusing connections for longer than the time specified 336132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 337132943Sgshapiro to high load, log this information. Patch from John Beck 338132943Sgshapiro of Sun Microsystems. 339132943Sgshapiro Remove the ability for non-trusted users to raise the value of 340132943Sgshapiro CheckpointInterval on the command line. 341132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 342132943Sgshapiro subset of the functionality of the 's' flag. 343132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 344132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 345132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 346132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 347132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 348132943Sgshapiro causing subsequent messages to be sent instead of being 349132943Sgshapiro discarded. This also caused milter callbacks to be called 350132943Sgshapiro out of order after the SMTP session was reset. 351132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 352132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 353132943Sgshapiro further information. 354132943Sgshapiro New command line option -D logfile to send debug output to 355132943Sgshapiro the indicated log file instead of stdout. 356132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 357132943Sgshapiro queue return and warning times for delivery status 358132943Sgshapiro notifications. 359132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 360132943Sgshapiro at all. 361132943Sgshapiro Several more return values for ruleset srv_features have been added 362132943Sgshapiro to enable/disable certain features in the server per 363132943Sgshapiro connection. See doc/op/op.me for details. 364132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 365132943Sgshapiro for DaemonPortOptions. 366132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 367132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 368132943Sgshapiro of Northern Illinois University. 369132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 370132943Sgshapiro be tried as a last resort after all other fallbacks. This 371132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 372132943Sgshapiro view of inside the company, but an incomplete view of 373132943Sgshapiro outside). From John Beck of Sun Microsystems. 374132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 375132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 376132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 377132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 378132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 379132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 380132943Sgshapiro of the University of Illinois at Urbana-Champaign. 381132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 382132943Sgshapiro applications for use in the xxfi_eom() callback. 383132943Sgshapiro New macro {time} which contains the output of the time(3) function, 384132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 385132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 386132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 387132943Sgshapiro terminate the SMTP session with a 421 error message. 388132943Sgshapiro Get rid of dead code that tried to access the environment variable 389132943Sgshapiro HOSTALIASES. 390132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 391132943Sgshapiro compile with -DUSE_TTYPATH=1. 392132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 393132943Sgshapiro the header value passed in without balancing quotes, 394132943Sgshapiro parentheses, and angle brackets. Based on patch from 395132943Sgshapiro Oleg Bulyzhin. 396132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 397132943Sgshapiro angle brackets when reading in rulesets. This allows 398132943Sgshapiro rules to be written for header checks to catch strings 399132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 400132943Sgshapiro Based on patch from Oleg Bulyzhin. 401132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 402132943Sgshapiro some temporary errors like ECONNABORTED. 403132943Sgshapiro Added list of CA certificates that are used by members of the 404132943Sgshapiro sendmail consortium, see CACerts. 405132943Sgshapiro Portability: 406132943Sgshapiro Two new compile options have been added: 407132943Sgshapiro HASCLOSEFROM System has closefrom(3). 408132943Sgshapiro HASFDWALK System has fdwalk(3). 409132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 410132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 411132943Sgshapiro change to using fcntl() locking until they can fix 412132943Sgshapiro it. Be sure to update other sendmail related 413132943Sgshapiro programs to match locking techniques. 414132943Sgshapiro New compile time option NEEDINTERRNO which should be set 415132943Sgshapiro if <errno.h> does not declare errno itself. 416132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 417132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 418132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 419132943Sgshapiro Center for Scientific Computing. 420132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 421132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 422132943Sgshapiro Remove path from compiler definition for Interix because 423132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 424132943Sgshapiro Also use <sys/mkdev.h> to get the correct 425132943Sgshapiro major()/minor() definitions. Based on feedback 426132943Sgshapiro from Mark Funkenhauser. 427132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 428132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 429132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 430132943Sgshapiro cf/sendmail.schema for more information. 431132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 432132943Sgshapiro is of the form "user:group" when used for submit.mc. 433132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 434132943Sgshapiro of Northern Illinois University. 435132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 436132943Sgshapiro instructs the check_* (except check_compat) to quarantine 437132943Sgshapiro the message using the given reason. 438132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 439132943Sgshapiro instead of "host" to avoid problem with looking up other 440132943Sgshapiro DNS records than just A. 441132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 442132943Sgshapiro length of the interval for which the number of incoming 443132943Sgshapiro connections is maintained. 444132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 445132943Sgshapiro rate control for individual hosts or nets. 446132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 447132943Sgshapiro number of open SMTP connections for individual hosts or nets. 448132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 449132943Sgshapiro slamming protection described above. The feature can 450132943Sgshapiro take an argument specifying the milliseconds to wait and/or 451132943Sgshapiro use the access database to look the pause time based on 452132943Sgshapiro client hostname, domain, IP address, or subnet. 453132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 454132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 455132943Sgshapiro rejections based on the unverified hostname of client, 456132943Sgshapiro which turns on the same behavior as in earlier sendmail 457132943Sgshapiro versions when delay_checks was not in use. See also entry 458132943Sgshapiro above about check_relay being invoked with ${client_name}. 459132943Sgshapiro CONFIG: New option confREJECT_LOG_INTERVAL to specify the log 460132943Sgshapiro interval when refusing connections for this long. 461132943Sgshapiro CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases 462132943Sgshapiro this requires a change in a mc file. Requested by 463132943Sgshapiro Ted Roberts of Electronic Data Systems. 464132943Sgshapiro CONFIG: New option confAUTH_REALM to set the authentication realm 465132943Sgshapiro that is passed to the Cyrus SASL library.

See cf/README for more information. 497132943Sgshapiro CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which 498132943Sgshapiro instructs the rulesets on whether or not to do a domain 499132943Sgshapiro lookup if a full address lookup doesn't match. See cf/README 500132943Sgshapiro for more information. 501132943Sgshapiro CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which 502132943Sgshapiro instructs the rulesets on whether or not to queue the mail 503132943Sgshapiro or give an SMTP temporary error if the LDAP server can't be 504132943Sgshapiro reached. See cf/README for more information. Based on 505132943Sgshapiro patch from Billy Ray Miller of Caterpillar. 506132943Sgshapiro CONFIG: Experimental support for MTAMark, see cf/README for details. 507132943Sgshapiro CONFIG: New option confMESSAGEID_HEADER to define a different 508132943Sgshapiro Message-Id: header format. Patch from Bastiaan Bakker 509132943Sgshapiro of LifeLine Networks. 510132943Sgshapiro CONTRIB: New version of cidrexpand which uses Net::CIDR. From 511132943Sgshapiro Derek J. Balling. 512132943Sgshapiro CONTRIB: oldbind.compat.c has been removed due to security problems. 513132943Sgshapiro Found by code inspection done by Reasoning, Inc. 514132943Sgshapiro DEVTOOLS: Add an example file for devtools/Site/, contributed 515132943Sgshapiro by Neil Rickert of Northern Illinois University. 516132943Sgshapiro LIBMILTER: Add new function smfi_quarantine() which allows the 517132943Sgshapiro filter's EOM routine to quarantine the current message. 518132943Sgshapiro Filters which use this function must include the 519132943Sgshapiro SMFIF_QUARANTINE flag in the registered smfiDesc structure. 520132943Sgshapiro LIBMILTER: If a milter sets the reply code to "421", the SMTP server 521132943Sgshapiro will terminate the SMTP session with that error. 522132943Sgshapiro LIBMILTER: Upon filter shutdown, libmilter will not remove a 523132943Sgshapiro named socket in the file system if it is running as root. 524132943Sgshapiro LIBMILTER: Add new function smfi_progress() which allows the filter 525132943Sgshapiro to notify the MTA that an EOM operation is still in progress, 526132943Sgshapiro resetting the timeout. 527132943Sgshapiro LIBMILTER: Add new function smfi_opensocket() which allows the filter 528132943Sgshapiro to attempt to establish the interface socket, and detect 529132943Sgshapiro failure to do so before calling smfi_main(). 530132943Sgshapiro LIBMILTER: Add new function smfi_setmlreply() which allows the 531132943Sgshapiro filter to return a multi-line SMTP reply. 532132943Sgshapiro LIBMILTER: Deal with more temporary errors in accept() by ignoring 533132943Sgshapiro them instead of stopping after too many occurred. 534132943Sgshapiro Suggested by James Carlson of Sun Microsystems. 535132943Sgshapiro LIBMILTER: Fix a descriptor leak in the sample program found in 536132943Sgshapiro docs/sample.html.

If you have an example of improper 620125820Sgshapiro 7 to 8 bit conversion please send it to us. 621125820Sgshapiro Return normal error code for unknown SMTP commands instead of 622125820Sgshapiro the one specified by check_relay or a milter for a 623125820Sgshapiro connection. Problem noted by Andrzej Filip. 624125820Sgshapiro Some ident responses contain data after the terminating CRLF which 625125820Sgshapiro causes sendmail to log "POSSIBLE ATTACK...newline in string". 626125820Sgshapiro To avoid this everything after LF is ignored. 627125820Sgshapiro If the operating system supports O_EXLOCK and HASFLOCK is set 628125820Sgshapiro then a possible race condition for creating qf files 629125820Sgshapiro can be avoided. Note: the race condition does not 630125820Sgshapiro exist within sendmail, but between sendmail and an 631125820Sgshapiro external application that accesses qf files. 632125820Sgshapiro Log the proper options name for TLS related mising files for 633125820Sgshapiro the CACertPath, CACertFile, and DHParameters options. 634125820Sgshapiro Do not split an envelope if it will be discarded, otherwise df 635125820Sgshapiro files could be left behind. Problem found by Wolfgang 636125820Sgshapiro Breyha. 637125820Sgshapiro The use of the environment variables HOME and HOSTALIASES has been 638125820Sgshapiro deprecated and will be removed in version 8.13. This only 639125820Sgshapiro effects configuration which preserve those variable via the 640125820Sgshapiro 'E' command in the cf file as sendmail clears out its entire 641125820Sgshapiro environment. 642125820Sgshapiro Portability: 643125820Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a.

Problem noted by Neil 925102528Sgshapiro Rickert of Northern Illinois University. 926102528Sgshapiro If applying a header check to a header with unstructured data, 927102528Sgshapiro e.g., Subject:, then do not run syntax checks that are 928102528Sgshapiro supposed for addresses on the header content. 929102528Sgshapiro Count messages rejected/discarded via the check_data ruleset. 930102528Sgshapiro Portability: 931102528Sgshapiro Fix compilation on systems which do not allow simple 932102528Sgshapiro copying of the variable argument va_list.

From Michel Bourget of SGI. 935102528Sgshapiro Add some additional IRIX shells to the default shell 936102528Sgshapiro list. From Michel Bourget of SGI. 937102528Sgshapiro Fix compilation issues on Mac OS X 10.2 (Darwin 6.0). 938102528Sgshapiro NETISO support has been dropped. 939102528Sgshapiro CONFIG: There was a seemingly minor change in 8.12.4 with respect 940102528Sgshapiro to handling entries of IP nets/addresses with RHS REJECT. 941102528Sgshapiro These would be rejected in check_rcpt instead of only 942102528Sgshapiro being activated in check_relay. This change has been made to 943102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 944102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 945102528Sgshapiro record for ..." if delay_checks is enabled. However, this 946102528Sgshapiro modification causes a change of behavior if an IP net/address 947102528Sgshapiro is listed in the access map with REJECT and a host/domain 948102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 949102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 950102528Sgshapiro change was made on request of Neil Rickert of Northern 951102528Sgshapiro Illinois University, the side effect has been found by 952102528Sgshapiro Stefaan Van Hoornick. 953102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 954102528Sgshapiro using the local hostname ($j) or domains in class {P}. 955102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 956102528Sgshapiro University. 957102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 958102528Sgshapiro Fix from Andrzej Filip. 959102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 960102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 961102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 962102528Sgshapiro NULL pointer.

Problem noted by Kevin 99498841Sgshapiro A. McGrail of Peregrine Hardware. 99598841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 99698841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 99798841Sgshapiro 8.13 will change the default locking method to 99898841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 99998841Sgshapiro want to do this in 8.12 by compiling with 100098841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 100198841Sgshapiro related programs to match locking techniques. 100298841Sgshapiro 100398121Sgshapiro8.12.4/8.12.4 2002/06/03 100498121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 100598121Sgshapiro can leave systems open to a local denial of service 100698121Sgshapiro attack.

In previous versions this could cause mail 109994334Sgshapiro not to be delivered if a queue file is repeatedly moved 110094334Sgshapiro by an external process whenever sendmail moved it back 110194334Sgshapiro into the right place. Some precautions have been taken 110294334Sgshapiro to avoid moving queue files if not really necessary. 110394334Sgshapiro sendmail may use links to refer to queue files and it 110494334Sgshapiro may store the path of data files in queue files. Hence 110594334Sgshapiro queue files should not be moved unless those internals 110694334Sgshapiro are understood and the integrity of the files is not 110794334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 110894334Sgshapiro University. 110994334Sgshapiro If an error mail is created, and the mail is split across different 111094334Sgshapiro queue directories, and SuperSafe is off, then write the mail 111194334Sgshapiro to disk before splitting it, otherwise an assertion is 111294334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 111394334Sgshapiro of INTERMETA. 111494334Sgshapiro Fix possible race condition that could cause sendmail to forget 111594334Sgshapiro running queues.

From 120994334Sgshapiro Rajesh Somasund of Hewlett-Packard. 121094334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 121194334Sgshapiro SMTP AUTH information. This feature was actually added in 121294334Sgshapiro 8.12.0 but a release note was not included. 121394334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 121494334Sgshapiro parameter is set and the LDAP lookup returns a temporary 121594334Sgshapiro error. 121694334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 121794334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 121894334Sgshapiro Krzysztof Oledzki. 121994334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 122094334Sgshapiro initialization as aliases are not needed for the MSP. 122194334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 122294334Sgshapiro is in use. Patch from Andrzej Filip. 122394334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 122494334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 122594334Sgshapiro This will only have an effect if a parameter is specified, 122694334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 122794334Sgshapiro it is embedded in square brackets. Problem noted by 122894334Sgshapiro Theo Van Dinter of Collective Technologies. 122994334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 123094334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 123194334Sgshapiro to allow for the proper time zone on systems where the 123294334Sgshapiro default results in misleading time stamps. That is, syslog 123394334Sgshapiro time stamps and Date headers on submitted mail will use the 123494334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 123594334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 123694334Sgshapiro by Neil Rickert of Northern Illinois University. 123794334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 123894334Sgshapiro binary.

Problem noted by Bjoern Voigt of TU Berlin. 133790792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 133890792Sgshapiro server gets stuck while processing that command. Problem 133990792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 134090792Sgshapiro In addition to printing errors when parsing recipients during 134190792Sgshapiro command line invocations log them to make it simpler 134290792Sgshapiro to understand possible DSNs to postmaster. 134390792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 134490792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 134590792Sgshapiro instead of forcing localhost. 134690792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 134790792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 134890792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 134990792Sgshapiro noted by Neil Rickert of Northern Illinois University. 135090792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 135190792Sgshapiro dropping the connection during an SMTP transaction, stop 135290792Sgshapiro sending commands. This prevents bogus "Bad file number" 135390792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 135490792Sgshapiro Worcester Polytechnic Institute. 135590792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 135690792Sgshapiro almost always too small; do not guess the size at all. 135790792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 135890792Sgshapiro Compaq Computer Corp. 135990792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 136090792Sgshapiro properly.

Problem 143590792Sgshapiro found by Michal Zalewski. 143690792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 143790792Sgshapiro privileges by disabling debugging (command line -d flag) 143890792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 143990792Sgshapiro used. Suggested by Michal Zalewski. 144090792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 144190792Sgshapiro Problem found by Michal Zalewski. 144290792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 144390792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 144490792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 144590792Sgshapiro If debugging is turned on (-d0.10) print not just the default 144690792Sgshapiro values for configuration file and pid file but also the 144790792Sgshapiro selected values. Problem noted by Brad Chapman. 144890792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 144990792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 145090792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 145190792Sgshapiro this only applied to hostname canonification. Problem 145290792Sgshapiro noted by Bill Fenner of AT&T Research. 145390792Sgshapiro Ignore comments in NIS host records when trying to find the 145490792Sgshapiro canonical name for a host. 145590792Sgshapiro When sendmail has extra privileges, limit mail submission command 145690792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 145790792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 145890792Sgshapiro suggestion from Michal Zalewski. 145990792Sgshapiro Portability: 146090792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 146190792Sgshapiro `uname` does not given complete information. 146290792Sgshapiro Problem noted by Keith Neufeld of the Cessna 146390792Sgshapiro Aircraft Company. 146490792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 146590792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 146690792Sgshapiro Avoid compiler warnings by not using pointers to pass 146790792Sgshapiro integers.

Suggested 151490792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 151590792Sgshapiro (IdS). 151690792Sgshapiro Fixed problem of a global variable being used for a timeout jump 151790792Sgshapiro point where the variable could become overused for more than 151890792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 151990792Sgshapiro a corrupted stack causing a core dump. The timeout is now 152090792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 152190792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 152290792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 152390792Sgshapiro checks (group ID of RunAsUser). This allows use of a 152490792Sgshapiro set-group-ID sendmail binary for initial message submission 152590792Sgshapiro and no set-user-ID root sendmail is needed. For details 152690792Sgshapiro see sendmail/SECURITY. 152790792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 152890792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 152990792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 153090792Sgshapiro with a fallback of sendmail.cf as configuration file. See 153190792Sgshapiro sendmail/SECURITY. 153290792Sgshapiro New configuration file option UseMSP to allow group writable queue 153390792Sgshapiro files if the group is the same as that of a set-group-ID 153490792Sgshapiro sendmail binary. See sendmail/SECURITY. 153590792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 153690792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 153790792Sgshapiro is sendmail.cf (to be backward compatible). This selection 153890792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 153990792Sgshapiro file: client or mta). See sendmail/SECURITY. 154090792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 154190792Sgshapiro command has been removed. 154290792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 154390792Sgshapiro at compile time or per host (ruleset). 154490792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 154590792Sgshapiro used to look up local mail recipients; the default value 154690792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 154790792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 154890792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 154990792Sgshapiro long, to accomodate envelope splitting. File systems with 155090792Sgshapiro a 14 character file name length limit are no longer 155190792Sgshapiro supported. 155290792Sgshapiro Recipient list used for delivery now gets internally ordered by 155390792Sgshapiro hostsignature (character string version of MX RR). This orders 155490792Sgshapiro recipients for the same MX RR's together meaning smaller 155590792Sgshapiro portions of the list need to be scanned (instead of the whole 155690792Sgshapiro list) each delivery() pass to determine piggybacking. The 155790792Sgshapiro significance of the change is better the larger the recipient 155890792Sgshapiro list. Hostsignature is now created during recipient list 155990792Sgshapiro creation rather than just before delivery. 156090792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 156190792Sgshapiro piggybacking (called coincidental) extended to coattail 156290792Sgshapiro piggybacking. Rather than complete MX RR matching 156390792Sgshapiro (coincidental) piggybacking is done if just the lowest value 156490792Sgshapiro preference matches (coattail). 156590792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 156690792Sgshapiro try other MX hosts if available. 156790792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 156890792Sgshapiro outgoing (client-side) SMTP Authentication. 156990792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 157090792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 157190792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 157290792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 157390792Sgshapiro A new ruleset authinfo can be used to return client side 157490792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 157590792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 157690792Sgshapiro removed in future versions. 157790792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 157890792Sgshapiro requires 334. Mercury 1.48 is a known offender. 157990792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 158090792Sgshapiro for the security layer in SMTP AUTH (SASL). See 158190792Sgshapiro doc/op/op.me for details. 158290792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 158390792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 158490792Sgshapiro signed the presented certificate, the CN and the MD5 hash 158590792Sgshapiro of the presented certificate, respectively. 158690792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 158790792Sgshapiro New ruleset srv_features to enable/disable certain features in the 158890792Sgshapiro server per connection. See doc/op/op.me for details. 158990792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 159090792Sgshapiro recipient; useful to decide whether a conection is secure 159190792Sgshapiro enough on a per recipient basis. 159290792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 159390792Sgshapiro for STARTTLS. 159490792Sgshapiro If no certificate has been requested, the macro {verify} has the 159590792Sgshapiro value "NOT". 159690792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 159790792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 159890792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 159990792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 160090792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 160190792Sgshapiro really required. This change results in a noticable 160290792Sgshapiro performance gains on most machines. Moreover, if shared 160390792Sgshapiro memory is in use, reuse the key several times. 160490792Sgshapiro Add queue groups which can be used to group queue directories with 160590792Sgshapiro the same behavior together. See doc/op/op.me for details. 160690792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 160790792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 160890792Sgshapiro are initially sorted which may result in faster envelope 160990792Sgshapiro splitting. If the mail is submitted directly from the 161090792Sgshapiro command line, then the value also limits the number of 161190792Sgshapiro processes to deliver the envelopes; if more envelopes are 161290792Sgshapiro created they are only queued up and must be taken care of 161390792Sgshapiro by a queue run. 161490792Sgshapiro The check for 'enough disk space' now pays attention to which file 161590792Sgshapiro system each queue directory resides in. 161690792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 161790792Sgshapiro New option QueueFileMode for the default permissions of queue files. 161890792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 161990792Sgshapiro group (one or more queues in a multi-queue environment 162090792Sgshapiro collected together) to process the same work list at the 162190792Sgshapiro same time. 162290792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 162390792Sgshapiro active queue runner processes. 162490792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 162590792Sgshapiro runners per queue group. 162690792Sgshapiro Queue member selection by substring pattern matching now allows 162790792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 162890792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 162990792Sgshapiro of the queue that match during processing. 163090792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 163190792Sgshapiro periodically forking a child to process the queue, a single 163290792Sgshapiro child is forked for each queue that sleeps between queue 163390792Sgshapiro runs. A SIGHUP signal can be sent to restart this 163490792Sgshapiro persistent queue runner. 163590792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 163690792Sgshapiro sendmail process which only runs the queue at an interval: 163790792Sgshapiro sendmail -q15m). 163890792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 163990792Sgshapiro Proposed by Thom O'Connor. 164090792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 164190792Sgshapiro unless the new -qf option or -v is used. 164290792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 164390792Sgshapiro several queue runners are started by hand to avoid contention. 164490792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 164590792Sgshapiro of the qf file (older entries first). 164690792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 164790792Sgshapiro a client to specify an amount of time within which an e-mail 164890792Sgshapiro should be delivered. New option DeliverByMin added to set the 164990792Sgshapiro minimum amount of time or disable the extension. 165090792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 165190792Sgshapiro not allowed unless escaped or quoted. 165290792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 165390792Sgshapiro by Leif Johansson of Stockholm University, which was based on 165490792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 165590792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 165690792Sgshapiro Technology, Stockholm, Sweden. 165790792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 165890792Sgshapiro behavior (no MX lookups), put the name in square brackets. 165990792Sgshapiro Proposed by Thom O'Connor. 166090792Sgshapiro Use shared memory to store free space of filesystems that are used 166190792Sgshapiro for queues, if shared memory is available and if a key is set 166290792Sgshapiro via SharedMemoryKey. This minimizes the number of system 166390792Sgshapiro calls to check the available space. See doc/op/op.me for 166490792Sgshapiro details. 166590792Sgshapiro If shared memory is compiled in the option -bP can be used to print 166690792Sgshapiro the number of entries in the queue(s). 166790792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 166890792Sgshapiro and the usual documentation for details. 166990792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 167090792Sgshapiro Remove '-U' (initial user submission) command line option as 167190792Sgshapiro announced in 8.10. 167290792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 167390792Sgshapiro New macro {addr_type} which contains whether the current address is 167490792Sgshapiro an envelope sender or recipient address. Suggested by 167590792Sgshapiro Neil Rickert of Northern Illinois University. 167690792Sgshapiro Two new options for host maps: -d (retransmission timeout), 167790792Sgshapiro -r (number of retries). 167890792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 167990792Sgshapiro separator such that a lookup can return both an attribute 168090792Sgshapiro and value separated by the given separator. 168190792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 168290792Sgshapiro to map class arith. 168390792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 168490792Sgshapiro (errors that occur when sending an error message) are dropped. 168590792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 168690792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 168790792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 168890792Sgshapiro requirements for files containing secret keys. This is 168990792Sgshapiro necessary for the MSP if client authentification is used. 169090792Sgshapiro Properly handle quoted filenames for class files (to allow for 169190792Sgshapiro filenames with spaces). 169290792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 169390792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 169490792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 169590792Sgshapiro {if_addr_out} address of interface of outgoing connection. 169690792Sgshapiro {if_family_out} family of interface of outgoing connection. 169790792Sgshapiro The latter two are only set if the interface does not belong 169890792Sgshapiro to the loopback net. 169990792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 170090792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 170190792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 170290792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 170390792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 170490792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 170590792Sgshapiro all connections for a single delivery attempt to succeed. 170690792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 170790792Sgshapiro a threshold number of recipients has been rejected (option 170890792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 170990792Sgshapiro Development Group. 171090792Sgshapiro New option DelayLA to delay connections if the load averages 171190792Sgshapiro exceeds the specified value. The default of 0 does not 171290792Sgshapiro change the previous behavior. A value greater than 0 171390792Sgshapiro will cause sendmail to sleep for one second on most 171490792Sgshapiro SMTP commands and before accepting connections if that 171590792Sgshapiro load average is exceeded. 171690792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 171790792Sgshapiro recipients that are sent during a connection to a mailer. 171890792Sgshapiro This also introduces a new mailer field 'r' which defines 171990792Sgshapiro the maximum number of recipients (defaults to 100). 172090792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 172190792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 172290792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 172390792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 172490792Sgshapiro instead. 172590792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 172690792Sgshapiro builtin mailer pathnames. Use TCP instead. 172790792Sgshapiro PH map code updated to use the new libphclient API instead of the 172890792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 172990792Sgshapiro University of Illinois at Urbana-Champaign. 173090792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 173190792Sgshapiro for direct (command line) submissions. 173290792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 173390792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 173490792Sgshapiro Hagino of the KAME Project. 173590792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 173690792Sgshapiro whose content is rewritten similar to Reply-To:. 173790792Sgshapiro Proposed by Andrzej Filip. 173890792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 173990792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 174090792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 174190792Sgshapiro AUTH/STARTTLS related logfile entries. 174290792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 174390792Sgshapiro before logging. 174490792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 174590792Sgshapiro (at LogLevel 9/10 or higher). 174690792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 174790792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 174890792Sgshapiro in which most commands are rejected due to check_relay or 174990792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 175090792Sgshapiro Change logging format for cloned envelopes to be similar to that for 175190792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 175290792Sgshapiro of the Universitat Regensburg. 175390792Sgshapiro Added libsm, a C library of general purpose abstractions including 175490792Sgshapiro assertions, tracing and debugging with named debug categories, 175590792Sgshapiro exception handling, malloc debugging, resource pools, 175690792Sgshapiro portability abstractions, and an extensible buffered I/O 175790792Sgshapiro package. It will at some point replace libsmutil. 175890792Sgshapiro See libsm/index.html for details. 175990792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 176090792Sgshapiro care of by fork() and exit(). 176190792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 176290792Sgshapiro more consistent portablity amongst different platforms 176390792Sgshapiro new and old (from new libsm). 176490792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 176590792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 176690792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 176790792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 176890792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 176990792Sgshapiro synchronizations calls. 177090792Sgshapiro Add per-recipient status information to mailq -v output. 177190792Sgshapiro T_ANY queries are no longer used by sendmail. 177290792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 177390792Sgshapiro too (see include/sm/cdefs.h for more info). 177490792Sgshapiro sendmail -d now has general support for named debug categories. 177590792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 177690792Sgshapiro for details. 177790792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 177890792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 177990792Sgshapiro generated by this condition were illegal (not RFC conform). 178090792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 178190792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 178290792Sgshapiro mailer and the recipient has hence been rejected during the 178390792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 178490792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 178590792Sgshapiro that do not have postmaster defined. If an email was sent 178690792Sgshapiro from an address to which a DSN cannot be returned and 178790792Sgshapiro in which at least one recipient address is non-deliverable, 178890792Sgshapiro then that email had been delivered in each queue run. 178990792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 179090792Sgshapiro degli Studi dell'Insubria. 179190792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 179290792Sgshapiro i.e., the corresponding code is always compiled in now. 179390792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 179490792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 179590792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 179690792Sgshapiro attempting to canonify a hostname, some broken nameservers 179790792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 179890792Sgshapiro lookups. If you want to excuse this behavior, use this new 179990792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 180090792Sgshapiro Mark Roth of the University of Illinois at 180190792Sgshapiro Urbana-Champaign. 180290792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 180390792Sgshapiro noted by Joy Latten of IBM. 180490792Sgshapiro ConnectionRateThrottle limits the number of connections per second 180590792Sgshapiro to each daemon individually, not the overall number of 180690792Sgshapiro connections. 180790792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 180890792Sgshapiro sendmail to use a default alias schema as outlined in the 180990792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 181090792Sgshapiro cf/README. 181190792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 181290792Sgshapiro the first character after the class name is not a '/' or a 181390792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 181490792Sgshapiro rest of the line will be parsed as a map lookup. This 181590792Sgshapiro allows classes to be filled via a map lookup. See op.me 181690792Sgshapiro for more syntax information. Specifically, this can be 181790792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 181890792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 181990792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 182090792Sgshapiro example). 182190792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 182290792Sgshapiro the default schema used in the above two items. 182390792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 182490792Sgshapiro warning if a program being run from a mailer or file class 182590792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 182690792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 182790792Sgshapiro if a program being run from a mailer or file class 182890792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 182990792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 183090792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 183190792Sgshapiro (without quotes) will disable this and return to the 183290792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 183390792Sgshapiro Suggested by Bryan Stansell of GNAC. 183490792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 183590792Sgshapiro HELO/EHLO commands. 183690792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 183790792Sgshapiro possible protocol family which may be used for outgoing 183890792Sgshapiro connections. Restrictions placed on one family only affect 183990792Sgshapiro outgoing connections on that particular family. Because of 184090792Sgshapiro this change, the ${client_flags} macro is not set until the 184190792Sgshapiro connection is established. Based on patch from Motonori 184290792Sgshapiro Nakamura of Kyoto University. 184390792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 184490792Sgshapiro when the -bv option is given by users who are neither root 184590792Sgshapiro nor the TrustedUser so users can not read private aliases, 184690792Sgshapiro forwards, or :include: files. It also will override the -v 184790792Sgshapiro (verbose) command line option. 184890792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 184990792Sgshapiro address can't be used for the outgoing connection, fall 185090792Sgshapiro back to the settings in ClientPortOptions (if set). 185190792Sgshapiro Problem noted by John Beck of Sun Microsystems. 185290792Sgshapiro New named config file rule check_data for DATA command (input: 185390792Sgshapiro number of recipients). Based on patch from Mark Roth of 185490792Sgshapiro the University of Illinois at Urbana-Champaign. 185590792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 185690792Sgshapiro can be specified using the '#' option character. For 185790792Sgshapiro example, 'ETRN #queuegroup'. 185890792Sgshapiro If an LDAP server times out or becomes unavailable, close the 185990792Sgshapiro current connection and reopen to get to one of the fallback 186090792Sgshapiro servers. Patch from Paul Hilchey of the University of 186190792Sgshapiro British Columbia. 186290792Sgshapiro Make default error number on $#error messages 550 instead of 501 186390792Sgshapiro because 501 is not allowed on all commands. 186490792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 186590792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 186690792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 186790792Sgshapiro if required. 186890792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 186990792Sgshapiro class instead. 187090792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 187190792Sgshapiro "IPv6:" tag to identify the address properly. For example, 187290792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 187390792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 187490792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 187590792Sgshapiro MTA is running. For example, during a queue run. 187690792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 187790792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 187890792Sgshapiro Nelson of IBM. 187990792Sgshapiro The maximum number of commands before the MTA slows down when too 188090792Sgshapiro many "light weight" commands have been received are now 188190792Sgshapiro configurable during compile time. The current values and 188290792Sgshapiro their defaults are: 188390792Sgshapiro MAXBADCOMMANDS 25 unknown commands 188490792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 188590792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 188690792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 188790792Sgshapiro MAXETRNCOMMANDS 8 ETRN 188890792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 188990792Sgshapiro Costales of SL3D, Inc. 189090792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 189190792Sgshapiro ${MyMacro} is defined but also that it is not empty. 189290792Sgshapiro Properly quote usernames with special characters if they are used 189390792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 189490792Sgshapiro Meteorological Institute. 189590792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 189690792Sgshapiro messages for messages for mailing list expanded addresses 189790792Sgshapiro which are not delivered on the initial attempt. 189890792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 189990792Sgshapiro the final dot has been sent to avoid affecting future 190090792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 190190792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 190290792Sgshapiro file systems that require to call fsync() for a directory 190390792Sgshapiro if the meta-data in it has been changed. This should be 190490792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 190590792Sgshapiro See sendmail/README for further information. 190690792Sgshapiro Avoid file locking deadlock when updating the statistics file if 190790792Sgshapiro sendmail is signaled to terminate. Problem noted by 190890792Sgshapiro Christophe Wolfhugel of France Telecom. 190990792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 191090792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 191190792Sgshapiro the Finnish Meteorological Institute. 191290792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 191390792Sgshapiro from Peter A. Friend of EarthLink. 191490792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 191590792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 191690792Sgshapiro flora.ca. 191790792Sgshapiro Portability: 191890792Sgshapiro Remove support for AIX 2, which supports only 14 character 191990792Sgshapiro filenames and is outdated anyway. Suggested by 192090792Sgshapiro Valdis Kletnieks of Virginia Tech. 192190792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 192290792Sgshapiro i.e., use default /usr/sbin, change owner/group 192390792Sgshapiro of man pages and user-executable to root/sys, set 192490792Sgshapiro optimization limit to 0 (unlimited). Based on patch 192590792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 192690792Sgshapiro Hurtta of the Finnish Meteorological Institute. 192790792Sgshapiro Do not assume LDAP support is installed by default under 192890792Sgshapiro Solaris 8 and later. 192990792Sgshapiro Add support for OpenUNIX. 193090792Sgshapiro CONFIG: Increment version number of config file to 10. 193190792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 193290792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 193390792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 193490792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 193590792Sgshapiro temporary lookup failures. 193690792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 193790792Sgshapiro action to be taken by aborting the search for domain names 193890792Sgshapiro or IP nets. 193990792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 194090792Sgshapiro relay address as long as the other part allows the email 194190792Sgshapiro to get through. 194290792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 194390792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 194490792Sgshapiro entry like user+*@domain. This allows handling of details by 194590792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 194690792Sgshapiro introduced to match only non-empty details of addresses. 194790792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 194890792Sgshapiro and hence there is no required order within the MAILER 194990792Sgshapiro section anymore except for MAILER(`uucp') which must come 195090792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 195190792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 195290792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 195390792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 195490792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 195590792Sgshapiro in the access map which returns OK or RELAY actually 195690792Sgshapiro terminates check_* ruleset checking. 195790792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 195890792Sgshapiro tls_rcpt, see cf/README for details. 195990792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 196090792Sgshapiro STARTTLS has been used to "(version=${tls_version} 196190792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 196290792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 196390792Sgshapiro options friends/haters instead of "To:" and enable 196490792Sgshapiro specification of whole domains instead of just users. 196590792Sgshapiro Notice: this change is not backward compatible. 196690792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 196790792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 196890792Sgshapiro cf/README for details. 196990792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 197090792Sgshapiro the access map.

Gumpertz of Computer Problem 198090792Sgshapiro Solving. 198190792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 198290792Sgshapiro options, see doc/op/op.me for details. 198390792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 198490792Sgshapiro the security layer in SMTP AUTH (SASL). 198590792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 198690792Sgshapiro immediately. 198790792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 198890792Sgshapiro allows checking of the return values of the DNS lookups. 198990792Sgshapiro See cf/README for details. 199090792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 199190792Sgshapiro temporary lookup failures. 199290792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 199390792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 199490792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 199590792Sgshapiro memory use. 199690792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 199790792Sgshapiro of the sender and the recipient address delimited by the 199890792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 199990792Sgshapiro in the access map. Based on code contributed by Mathias 200090792Sgshapiro Koerber of Singapore Telecommunications Ltd. 200190792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 200290792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 200390792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 200490792Sgshapiro via LMTP.

New option -D mbdb specifies the 209690792Sgshapiro mailbox database type. 209790792Sgshapiro MAIL.LOCAL: New option "-h filename" which instructs mail.local to 209890792Sgshapiro deliver the mail to the named file in the user's home 209990792Sgshapiro directory instead of the system mail spool area. Based on 210090792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 210190792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 210290792Sgshapiro doesn't truncate the statistics file. 210390792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 210490792Sgshapiro instead of white space. 210590792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 210690792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 210790792Sgshapiro Meteorological Institute. 210890792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 210990792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 211090792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 211190792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 211290792Sgshapiro instead of syslog. 211390792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 211490792Sgshapiro in the password file. The -f and -m options must be used 211590792Sgshapiro to specify the database and message file since there is no 211690792Sgshapiro home directory for the default settings for these options. 211790792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 211890792Sgshapiro local mail recipients; it reads the MailboxDatabase option 211990792Sgshapiro from the sendmail.cf file. New option -C cffile which 212090792Sgshapiro specifies the path of the sendmail.cf file. 212190792Sgshapiro New Directories: 212290792Sgshapiro libmilter/docs 212390792Sgshapiro New Files: 212490792Sgshapiro cf/cf/README 212590792Sgshapiro cf/cf/submit.cf 212690792Sgshapiro cf/cf/submit.mc 212790792Sgshapiro cf/feature/authinfo.m4 212890792Sgshapiro cf/feature/compat_check.m4 212990792Sgshapiro cf/feature/enhdnsbl.m4 213090792Sgshapiro cf/feature/msp.m4 213190792Sgshapiro cf/feature/local_no_masquerade.m4 213290792Sgshapiro cf/feature/lookupdotdomain.m4 213390792Sgshapiro cf/feature/preserve_luser_host.m4 213490792Sgshapiro cf/feature/preserve_local_plus_detail.m4 213590792Sgshapiro cf/feature/queuegroup.m4 213690792Sgshapiro cf/sendmail.schema 213790792Sgshapiro contrib/dnsblaccess.m4 213890792Sgshapiro devtools/M4/UNIX/sm-test.m4 213990792Sgshapiro devtools/OS/OpenUNIX.5.i386 214090792Sgshapiro editmap/* 214190792Sgshapiro include/sm/* 214290792Sgshapiro libsm/* 214390792Sgshapiro libsmutil/cf.c 214490792Sgshapiro libsmutil/err.c 214590792Sgshapiro sendmail/SECURITY 214690792Sgshapiro sendmail/TUNING 214790792Sgshapiro sendmail/bf.c 214890792Sgshapiro sendmail/bf.h 214990792Sgshapiro sendmail/sasl.c 215090792Sgshapiro sendmail/sm_resolve.c 215190792Sgshapiro sendmail/sm_resolve.h 215290792Sgshapiro sendmail/tls.c 215390792Sgshapiro Deleted Files: 215490792Sgshapiro cf/feature/rbl.m4 215590792Sgshapiro cf/ostype/aix2.m4 215690792Sgshapiro devtools/OS/AIX.2 215790792Sgshapiro include/sendmail/cdefs.h 215890792Sgshapiro include/sendmail/errstring.h 215990792Sgshapiro include/sendmail/useful.h 216090792Sgshapiro libsmutil/errstring.c 216190792Sgshapiro sendmail/bf_portable.c 216290792Sgshapiro sendmail/bf_portable.h 216390792Sgshapiro sendmail/bf_torek.c 216490792Sgshapiro sendmail/bf_torek.h 216590792Sgshapiro sendmail/clock.c 216690792Sgshapiro Renamed Files: 216790792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 216890792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 216990792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 217090792Sgshapiro 2171120256Sgshapiro8.11.7/8.11.7 2003/03/29 2172120256Sgshapiro SECURITY: Fix a remote buffer overflow in header parsing by 2173120256Sgshapiro dropping sender and recipient header comments if the 2174120256Sgshapiro comments are too long. Problem noted by Mark Dowd 2175120256Sgshapiro of ISS X-Force. 2176120256Sgshapiro SECURITY: Fix a buffer overflow in address parsing due to 2177120256Sgshapiro a char to int conversion problem which is potentially 2178120256Sgshapiro remotely exploitable. Problem found by Michal Zalewski. 2179120256Sgshapiro Note: an MTA that is not patched might be vulnerable to 2180120256Sgshapiro data that it receives from untrusted sources, which 2181120256Sgshapiro includes DNS. 2182120256Sgshapiro To provide partial protection to internal, unpatched sendmail MTAs, 2183120256Sgshapiro 8.11.7 changes by default (char)0xff to (char)0x7f in 2184120256Sgshapiro headers etc. To turn off this conversion compile with 2185120256Sgshapiro -DALLOW_255 or use the command line option -d82.101. 2186120256Sgshapiro To provide partial protection for internal, unpatched MTAs that may be 2187120256Sgshapiro performing 7->8 or 8->7 bit MIME conversions, the default 2188120256Sgshapiro for MaxMimeHeaderLength has been changed to 2048/1024. 2189120256Sgshapiro Note: this does have a performance impact, and it only 2190120256Sgshapiro protects against frontal attacks from the outside. 2191120256Sgshapiro To disable the checks and return to pre-8.11.7 defaults, 2192120256Sgshapiro set MaxMimeHeaderLength to 0/0. 2193120256Sgshapiro Properly clean up macros to avoid persistence of session data 2194120256Sgshapiro across various connections. This could cause session 2195120256Sgshapiro oriented restrictions, e.g., STARTTLS requirements, 2196120256Sgshapiro to erroneously allow a connection.

Audit 243171345Sgshapiro other array indexing. This bug is not believed to be 243271345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 243371345Sgshapiro Schools" project (IdS). 243471345Sgshapiro Add an FFR (for future release) to drop privileges when using 243571345Sgshapiro address test mode. This will be turned on in 8.12. It can 243671345Sgshapiro be enabled by compiling with: 243771345Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 243871345Sgshapiro in your devtools/Site/site.config.m4 file. Suggested by 243971345Sgshapiro Michal Zalewski of the "Internet for Schools" project (IdS). 244071345Sgshapiro Fix potential problem with Cyrus-SASL security layer which may have 244171345Sgshapiro caused I/O errors, especially for mechanism DIGEST-MD5. 244271345Sgshapiro When QueueSortOrder was set to host, sendmail might not read 244371345Sgshapiro enough of the queue file to determine the host, making the 244471345Sgshapiro sort sub-optimal. Problem noted by Jeff Earickson of 244571345Sgshapiro Colby College. 244671345Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 244771345Sgshapiro RFC 1891) but don't have FAILURE as value. 244871345Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 244971345Sgshapiro This implies that every change to SASL related files requires 245071345Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 245171345Sgshapiro mechanisms (in form of shared libraries). 245271345Sgshapiro Properly set the STARTTLS related macros during a queue run for 245371345Sgshapiro a cached connection. Bug reported by Michael Kellen of 245471345Sgshapiro NxNetworks, Inc. 245571345Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 245671345Sgshapiro client name. 245771345Sgshapiro Include original length of bad field/header when reporting 245871345Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 245971345Sgshapiro the Universitat Regensburg. 246071345Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 246171345Sgshapiro DeliveryMode queue.

Patch from 247371345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 247471345Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 247571345Sgshapiro Meteorological Institute. 247671345Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 247771345Sgshapiro of the parameters to find Family= setting before trying to 247871345Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 247971345Sgshapiro Kletnieks of Virginia Tech. 248071345Sgshapiro When delivering to a file directly from an alias, do not call 248171345Sgshapiro initgroups(); instead use the DefaultUser group information. 248271345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 248371345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 248471345Sgshapiro created. Otherwise, sendmail can not remove it upon 248571345Sgshapiro close. Problem noted by Werner Wiethege. 248671345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 248771345Sgshapiro overall connections, not the number of connections per 248871345Sgshapiro socket. A future version may change this to per socket 248971345Sgshapiro counting. 249071345Sgshapiro Portability: 249171345Sgshapiro Clean up libsmdb so it functions properly on platforms 249271345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t). Problem 249371345Sgshapiro noted by Rein Tollevik of Basefarm AS. 249471345Sgshapiro Fix man page formatting for compatibility with Solaris' 249571345Sgshapiro whatis.

From Mark 252671345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 252771345Sgshapiro DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4 252871345Sgshapiro variables into bldOS, bldREL, and bldARCH to prevent 252973188Sgshapiro namespace collisions. Problem noted by Motonori Nakamura 253071345Sgshapiro of Kyoto University. 253171345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 253271345Sgshapiro causes some changes in behavior and may break rmail for 253371345Sgshapiro installations where sendmail is actually a wrapper to 253471345Sgshapiro another MTA. The change will re-appear in a future 253571345Sgshapiro version. 253671345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 253771345Sgshapiro and SunOS 5.8.

Fix from John Beck of Sun Microsystems. 255066494Sgshapiro Don't try STARTTLS in the client if the PRNG has not been properly 255166494Sgshapiro seeded. This problem only occurs on systems without 255266494Sgshapiro /dev/urandom. Problem detected by Jan Krueger of 255366494Sgshapiro digitalanswers communications consulting gmbh and 255466494Sgshapiro Neil Rickert of Northern Illinois University. 255566494Sgshapiro Don't use the . and .. directories when expanding QueueDirectory 255666494Sgshapiro wildcards. 255766494Sgshapiro Do not try to cache LDAP connections across processes as a parent 255866494Sgshapiro process may close the connection before the child process 255966494Sgshapiro has completed. Problem noted by Lai Yiu Fai of the Hong 256066494Sgshapiro Kong University of Science and Technology and Wolfgang 256166494Sgshapiro Hottgenroth of UUNET. 256266494Sgshapiro Use Timeout.fileopen to limit the amount of time spent trying to 256366494Sgshapiro read the LDAP secret from a file. 256466494Sgshapiro Prevent SIGTERM from removing a command line submitted item after 256566494Sgshapiro the user submits the message and before the first delivery 256666494Sgshapiro attempt completes. Problem noted by Max France of AlphaNet. 256766494Sgshapiro Fix from Neil Rickert of Northern Illinois University. 256866494Sgshapiro Deal correctly with MaxMessageSize restriction if message size is 256971345Sgshapiro greater than 2^31. Problem noted by Tim "Darth Dice" Bosserman 257071345Sgshapiro of EarthLink. 257166494Sgshapiro Turn off queue checkpointing if CheckpointInterval is set to zero. 257266494Sgshapiro Treat an empty home directory (from getpw*() or $HOME) as 257366494Sgshapiro non-existent instead of treating it as /. Problem noted by 257466494Sgshapiro Todd C. Miller of Courtesan Consulting. 257566494Sgshapiro Don't drop duplicate headers when reading a queued item. Problem 257666494Sgshapiro noted by Motonori Nakamura of Kyoto University. 257766494Sgshapiro Avoid bogus error text when logging the savemail panic "cannot 257866494Sgshapiro save rejected email anywhere". Problem noted by Marc G. 257966494Sgshapiro Fournier of Acadia University. 258066494Sgshapiro If an LDAP search fails because the LDAP server went down, close 258166494Sgshapiro the map so subsequent searches reopen the map. If there are 258266494Sgshapiro multiple LDAP servers, the down server will be skipped and 258366494Sgshapiro one of the others may be able to take over. 258466494Sgshapiro Set the ${load_avg} macro to the current load average, not the 258566494Sgshapiro previous load average query result. 258666494Sgshapiro If a non-optional map used in a check_* ruleset can't be opened, 258766494Sgshapiro return a temporary failure to the remote SMTP client 258866494Sgshapiro instead of ignoring the map. Problem noted by Allan E 258966494Sgshapiro Johannesen of Worcester Polytechnic Institute. 259066494Sgshapiro Avoid a race condition when queuing up split envelopes by saving 259166494Sgshapiro the split envelopes before the original envelope. 259266494Sgshapiro Fix a bug in the PH_MAP code which caused mail to bounce instead of 259366494Sgshapiro defer if the PH server could not be contacted. From Mark 259466494Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 259566494Sgshapiro Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and 259666494Sgshapiro ETRN.

Patch from Paul Hilchey of the 260466494Sgshapiro University of British Columbia. 260566494Sgshapiro Portability: 260666494Sgshapiro Move the NETINET6 define to devtools/OS/SunOS.5.{8,9} 260766494Sgshapiro instead of defining it in conf.h so users can 260866494Sgshapiro override the setting. Suggested by 260966494Sgshapiro Henrik Nordstrom of Ericsson. 261066494Sgshapiro On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of 261166494Sgshapiro /usr/lib/sendmail for rmail and vacation. From 261266494Sgshapiro Jeff A. Earickson of Colby College. 261366494Sgshapiro On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which 261466494Sgshapiro does not exist). From Jeff A. Earickson of Colby 261566494Sgshapiro College. 261666494Sgshapiro Avoid using the UCB subsystem on NCR MP-RAS 3.x. From 261766494Sgshapiro Tom Moore of NCR. 261866494Sgshapiro NeXT 3.X and 4.X installs man pages in /usr/man. From 261966494Sgshapiro Hisanori Gogota of NTT/InterCommunicationCenter. 262066494Sgshapiro Solaris 8 and later include /var/run. The default PID file 262166494Sgshapiro location is now /var/run/sendmail.pid. From John 262266494Sgshapiro Beck of Sun Microsystems. 262366494Sgshapiro SFIO includes snprintf() for those operating systems 262466494Sgshapiro which do not. From Todd C. Miller of Courtesan 262566494Sgshapiro Consulting. 262666494Sgshapiro CONFIG: Use the result of _CERT_REGEX_SUBJECT_ not {cert_subject}. 262766494Sgshapiro Problem noted by Kaspar Brand of futureLab AG. 262866494Sgshapiro CONFIG: Change 553 SMTP reply code to 501 to avoid problems with 262966494Sgshapiro errors in the MAIL address. 263066494Sgshapiro CONFIG: Fix FEATURE(nouucp) usage in example .mc files. Problem 263166494Sgshapiro noted by Ron Jarrell of Virginia Tech. 263266494Sgshapiro CONFIG: Add support for Solaris 8 (and later) as OSTYPE(solaris8). 263366494Sgshapiro Contributed by John Beck of Sun Microsystems. 263466494Sgshapiro CONFIG: Set confFROM_HEADER such that the mail hub can possibly add 263566494Sgshapiro GECOS information for an address. This more closely 263666494Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 263766494Sgshapiro Ericsson. 263866494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 263966494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 264066494Sgshapiro mailer as described in cf/README. 264166494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 264266494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 264366494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 264466494Sgshapiro makemap to 'unmake' the map. 264566494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 264666494Sgshapiro sendmail. 264766494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 264866494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 264966494Sgshapiro Meteorological Institute. 265066494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 265166494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 265266494Sgshapiro dot as the only character on the line. 265366494Sgshapiro New Files: 265466494Sgshapiro cf/ostype/solaris8.m4 265566494Sgshapiro 265664562Sgshapiro8.11.0/8.11.0 2000/07/19 265764562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 265864562Sgshapiro (not the normal case), some operating systems will still 265964562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 266064562Sgshapiro to drop all of its privileges. If sendmail needs to drop 266164562Sgshapiro these privileges and the operating system doesn't set the 266264562Sgshapiro saved-uid as well, exit with an error. Problem noted by 266364562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 266464562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 266564562Sgshapiro it populates. It is possible that some broken 266664562Sgshapiro implementations of snprintf() exist that do not do this. 266764562Sgshapiro Systems in this category should compile with 266864562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 266964562Sgshapiro system and report broken implementations to 267064562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 267164562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 267264562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 267364562Sgshapiro Implementation influenced by the example programs of 267464562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 267564562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 267664562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 267764562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 267864562Sgshapiro cf/README and doc/op/op.*. 267964562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 268064562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 268164562Sgshapiro ${server_name}, and ${server_addr}. These are documented 268264562Sgshapiro in cf/README and doc/op/op.*. 268364562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 268464562Sgshapiro random data. 268564562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 268664562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 268764562Sgshapiro try to use STARTTLS despite the security problems. 268864562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 268964562Sgshapiro support encryption. Based on code contributed by Tim 269064562Sgshapiro Martin of CMU. 269164562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 269264562Sgshapiro strength factor. 269364562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 269464562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 269564562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 269664562Sgshapiro of CMU. 269764562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 269864562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 269964562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 270064562Sgshapiro Fix the default family selection for DaemonPortOptions. As 270164562Sgshapiro documented, unless a family is specified in a 270264562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 270364562Sgshapiro also the default if no DaemonPortOptions value is set. 270464562Sgshapiro Therefore, IPv6 users should configure additional sockets 270564562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 270664562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 270764562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 270864562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 270964562Sgshapiro the interface information for an outgoing connection. 271064562Sgshapiro Not doing so was creating a mismatch between the socket 271164562Sgshapiro family and address used in subsequent connections if the 271264562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 271364562Sgshapiro by John Beck of Sun Microsystems. 271464562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 271564562Sgshapiro family based on the IP address. ${if_family} is no longer 271664562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 271764562Sgshapiro of Sun Microsystems. 271864562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 271964562Sgshapiro macros for both the incoming interface address/family and 272064562Sgshapiro the outgoing interface address/family.

This option and 303764562Sgshapiro its use is deprecated and will be removed from a future 303864562Sgshapiro version of sendmail. 303964562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 304064562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 304164562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 304264562Sgshapiro (IdS). 304364562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 304464562Sgshapiro a large number of files. See cf/README for more details. 304564562Sgshapiro The directory structure of the distribution has changed slightly 304664562Sgshapiro for easier code sharing among the programs. 304764562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 304864562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 304964562Sgshapiro which hold the client's authentication credentials, 305064562Sgshapiro the mechanism used for authentication, and the 305164562Sgshapiro authorization identity (i.e., the AUTH= parameter if 305264562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 305364562Sgshapiro On systems which use the Torek stdio library (all of the BSD 305464562Sgshapiro distributions), use memory-buffered files to reduce 305564562Sgshapiro file system overhead by not creating temporary files on 305664562Sgshapiro disk. Contributed by Exactis.com, Inc. 305764562Sgshapiro New option DataFileBufferSize to control the maximum size of a 305864562Sgshapiro memory-buffered data (df) file before a disk-based file is 305964562Sgshapiro used. Contributed by Exactis.com, Inc. 306064562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 306164562Sgshapiro memory-buffered transcript (xf) file before a disk-based 306264562Sgshapiro file is used. Contributed by Exactis.com, Inc. 306364562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 306464562Sgshapiro now listen on several different ports. Use: 306564562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 306664562Sgshapiro to run a Message Submission Agent (MSA); this is turned 306764562Sgshapiro on by default in m4-generated .cf files; it can be turned 306864562Sgshapiro off with FEATURE(`no_default_msa'). 306964562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 307064562Sgshapiro begin using RFC 2476 Message Submission for initial user 307164562Sgshapiro message submission. XUSR may disappear from a future release. 307264562Sgshapiro The new '-G' (relay (gateway) submission) command line option 307364562Sgshapiro indicates that the message being submitted from the command 307464562Sgshapiro line is for relaying, not initial submission. This means 307564562Sgshapiro the message will be rejected if the addresses are not fully 307664562Sgshapiro qualified and no canonicalization will be done. Future 307764562Sgshapiro releases may even reject improperly formed messages. 307864562Sgshapiro The '-U' (initial user submission) command line option is 307964562Sgshapiro deprecated and may be removed from a future release. 308064562Sgshapiro Mail user agents should begin using '-G' to indicate that 308164562Sgshapiro this is a relay submission (the inverse of -U). 308264562Sgshapiro The next release of sendmail will assume that any message submitted 308364562Sgshapiro from the command line is an initial user submission and act 308464562Sgshapiro accordingly. 308564562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 308664562Sgshapiro program or deliver to file as the owner of that file, the 308764562Sgshapiro address is marked as unsafe. This means if RunAsUser is 308864562Sgshapiro set, users won't be able to use programs or delivery to 308964562Sgshapiro files in their .forward files. Administrators can override 309064562Sgshapiro this by setting the DontBlameSendmail option to the new 309164562Sgshapiro setting NonRootSafeAddr. 309264562Sgshapiro Allow group or world writable directories if the sticky bit is set 309364562Sgshapiro on the directory and DontBlameSendmail is set to 309464562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 309564562Sgshapiro InCert Software. 309664562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 309764562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 309864562Sgshapiro set in the DontBlameSendmail option. Requested by many. 309964562Sgshapiro New Timeout.control option to limit the total time spent satisfying 310064562Sgshapiro a control socket request. 310164562Sgshapiro New Timeout.resolver options for controlling BIND resolver 310264562Sgshapiro settings: 310364562Sgshapiro Timeout.resolver.retrans 310464562Sgshapiro Sets the resolver's retransmission time interval (in 310564562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 310664562Sgshapiro and Timeout.resolver.retrans.normal. 310764562Sgshapiro Timeout.resolver.retrans.first 310864562Sgshapiro Sets the resolver's retransmission time interval (in 310964562Sgshapiro seconds) for the first attempt to deliver a message. 311064562Sgshapiro Timeout.resolver.retrans.normal 311164562Sgshapiro Sets the resolver's retransmission time interval (in 311264562Sgshapiro seconds) for all resolver lookups except the first 311364562Sgshapiro delivery attempt. 311464562Sgshapiro Timeout.resolver.retry 311564562Sgshapiro Sets the number of times to retransmit a resolver 311664562Sgshapiro query. Sets both Timeout.resolver.retry.first 311764562Sgshapiro and Timeout.resolver.retry.normal. 311864562Sgshapiro Timeout.resolver.retry.first 311964562Sgshapiro Sets the number of times to retransmit a resolver 312064562Sgshapiro query for the first attempt to deliver a message. 312164562Sgshapiro Timeout.resolver.retry.normal 312264562Sgshapiro Sets the number of times to retransmit a resolver 312364562Sgshapiro query for all resolver lookups except the first 312464562Sgshapiro delivery attempt. 312564562Sgshapiro Contributed by Exactis.com, Inc. 312664562Sgshapiro Support multiple queue directories. To use multiple queues, supply 312764562Sgshapiro a QueueDirectory option value ending with an asterisk. For 312864562Sgshapiro example, /var/spool/mqueue/q* will use all of the 312964562Sgshapiro directories or symbolic links to directories beginning with 313064562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 313164562Sgshapiro mind, the queue directory structure should not be changed 313264562Sgshapiro while sendmail is running. Queue runs create a separate 313364562Sgshapiro process for running each queue unless the verbose flag is 313464562Sgshapiro given on a non-daemon queue run. New items are randomly 313564562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 313664562Sgshapiro Support different directories for qf, df, and xf queue files; if 313764562Sgshapiro subdirectories or symbolic links to directories of those names 313864562Sgshapiro exist in the queue directories, they are used for the 313964562Sgshapiro corresponding queue files. Keep in mind, the queue 314064562Sgshapiro directory structure should not be changed while sendmail is 314164562Sgshapiro running. Proposed by Mathias Koerber of Singapore 314264562Sgshapiro Telecommunications Ltd. 314364562Sgshapiro New queue file naming system which uses a filename guaranteed to be 314464562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 314564562Sgshapiro without fancy file system locking. Queued items can be 314664562Sgshapiro moved between queues easily. Contributed by Exactis.com, 314764562Sgshapiro Inc. 314864562Sgshapiro Messages which are undeliverable due to temporary address failures 314964562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 315064562Sgshapiro set. Contributed by Exactis.com, Inc. 315164562Sgshapiro New command line option '-L tag' which sets the identifier used for 315264562Sgshapiro syslog. Contributed by Exactis.com, Inc. 315364562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 315464562Sgshapiro avoids opening and reading each queue file when preparing 315564562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 315664562Sgshapiro Shared memory counters and microtimers functionality has been 315764562Sgshapiro donated by Exactis.com, Inc. 315864562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 315964562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 316064562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 316164562Sgshapiro being added. Suggested by Michael K. Sanders. 316264562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 316364562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 316464562Sgshapiro and John Beck of Sun Microsystems. 316564562Sgshapiro In low-disk space situations, where sendmail would previously refuse 316664562Sgshapiro connections, still accept them, but only allow ETRN commands. 316764562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 316864562Sgshapiro Ltd. 316964562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 317064562Sgshapiro on systems which support them. This can be used with LMTP 317164562Sgshapiro local delivery agents which listen on a named socket. An 317264562Sgshapiro example mailer might be: 317364562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 317464562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 317564562Sgshapiro A=FILE /var/run/lmtpd 317664562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 317764562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 317864562Sgshapiro instead. 317964562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 318064562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 318164562Sgshapiro connections), IPC (which will be deprecated in a future 318264562Sgshapiro version), and FILE (for UNIX domain socket delivery). 318364562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 318464562Sgshapiro flags. 318564562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 318664562Sgshapiro body of the original message on delivery status 318764562Sgshapiro notifications. 318864562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 318964562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 319064562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 319164562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 319264562Sgshapiro Steve Schweinhart of America Online. 319364562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 319464562Sgshapiro not be set after rulesets are defined. Suggested by 319564562Sgshapiro Mitchell Blank Jr of Exec-PC. 319664562Sgshapiro Do not report temporary failure on delivery to files. In 319764562Sgshapiro interactive delivery mode, this would result in two SMTP 319864562Sgshapiro responses after the DATA command. Problem noted by 319964562Sgshapiro Nik Conwell of Boston University. 320064562Sgshapiro Check file close when mailing to files. Problem noted by Nik 320164562Sgshapiro Conwell of Boston University. 320264562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 320364562Sgshapiro Curtis W. Hillegas of Princeton University. 320464562Sgshapiro Always bind to the LDAP server regardless of whether you are using 320564562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 320664562Sgshapiro @Home Network. 320764562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 320864562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 320964562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 321064562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 321164562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 321264562Sgshapiro similar to check_rcpt etc. 321364562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 321464562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 321564562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 321664562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 321764562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 321864562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 321964562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 322064562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 322164562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 322264562Sgshapiro the corresponding DSN parameter values. Proposed by 322364562Sgshapiro Mathias Herberts. 322464562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 322564562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 322664562Sgshapiro before the message has been collected, thereafter it holds 322764562Sgshapiro the message size as computed by sendmail (and can be used 322864562Sgshapiro in check_compat). 322964562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 323064562Sgshapiro sendmail is using instead of the value of the DeliveryMode 323164562Sgshapiro option. 323264562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 323364562Sgshapiro Drop explicit From: if same as what would be generated only if it is 323464562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 323564562Sgshapiro Write pid to file also if sendmail only processes the queue. 323664562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 323764562Sgshapiro Log "low on disk space" only when necessary. 323864562Sgshapiro New macro ${load_avg} can be used to check the current load average. 323964562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 324064562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 324164562Sgshapiro is set. 324264562Sgshapiro Flag -S for maps to specify the character which is substituted 324364562Sgshapiro for spaces (instead of the default given by O BlankSub). 324464562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 324564562Sgshapiro This flag is set by default for the host map. Based on a 324664562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 324764562Sgshapiro Open maps only on demand, not at startup. 324864562Sgshapiro Log warning about unsupported IP address families. 324964562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 325064562Sgshapiro of the sum of all headers. This can be used to prevent 325164562Sgshapiro a denial-of-service attack. 325264562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 325364562Sgshapiro headers and parameters within those headers. This option 325464562Sgshapiro is intended to protect mail user agents from buffer 325564562Sgshapiro overflow attacks. 325664562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 325764562Sgshapiro alias recursion. 325864562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 325964562Sgshapiro Map type syslog to log the key via syslogd. 326064562Sgshapiro Entries in the alias file can be continued by putting a backslash 326164562Sgshapiro directly before the newline. 326264562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 326364562Sgshapiro dead.letter file, formerly hardcoded to 326464562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 326564562Sgshapiro default), sendmail will not attempt to save to a 326664562Sgshapiro system-wide dead.letter file if it can not bounce the mail 326764562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 326864562Sgshapiro file as it has in the past when the dead.letter file 326964562Sgshapiro could not be opened. 327064562Sgshapiro New option PidFile to define the location of the pid file. The 327164562Sgshapiro value of this option is macro expanded. 327264562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 327364562Sgshapiro process title shown in 'ps' listings. 327464562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 327564562Sgshapiro (along with the already existing macros): 327664562Sgshapiro ${daemon_info} Daemon information, e.g. 327764562Sgshapiro SMTP+queueing@00:30:00 327864562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 327964562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 328064562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 328164562Sgshapiro ${daemon_port} Daemon port, e.g., 25 328264562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 328364562Sgshapiro New macros especially for virtual hosting: 328464562Sgshapiro ${if_name} hostname of interface of incoming connection. 328564562Sgshapiro ${if_addr} address of interface of incoming connection. 328664562Sgshapiro The latter is only set if the interface does not belong to the 328764562Sgshapiro loopback net. 328864562Sgshapiro If a message being accepted via a method other than SMTP and 328964562Sgshapiro would be rejected by a header check, do not send the message. 329064562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 329164562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 329264562Sgshapiro Provide header value as quoted string in the macro 329364562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 329464562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 329564562Sgshapiro The length of the header value is stored in ${hdrlen}. 329664562Sgshapiro H*: allows to specify a default ruleset for header checks. This 329764562Sgshapiro ruleset will only be called if the individual header does 329864562Sgshapiro not have its own ruleset assigned. Suggested by Jan 329964562Sgshapiro Krueger of Unix-AG of University of Hannover. 330064562Sgshapiro The name of the header field stored in ${hdr_name}. 330164562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 330264562Sgshapiro removed if the config file version is greater than or equal 330364562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 330464562Sgshapiro input "token (1)" but does not match "token". 330564562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 330664562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 330764562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 330864562Sgshapiro Ericsson. 330964562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 331064562Sgshapiro messages with 8-bit text in headers. Problem noted by 331164562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 331264562Sgshapiro of Ericsson. 331364562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 331464562Sgshapiro modified database map file. Problem noted by Chris Adams 331564562Sgshapiro of Renaissance Internet Services. 331664562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 331764562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 331864562Sgshapiro queue up the message instead of bouncing it. 331964562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 332064562Sgshapiro standard does not provide any indication of what to do when 332164562Sgshapiro something other than 250 is received. Based on a patch 332264562Sgshapiro from Steve Schweinhart of America Online. 332364562Sgshapiro New option TrustedUser allows to specify a user who can own 332464562Sgshapiro important files instead of root. This requires HASFCHOWN. 332564562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 332664562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 332764562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 332864562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 332964562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 333064562Sgshapiro $? tests also whether the macro is non-null. 333164562Sgshapiro Print an error message if a mailer definition contains an invalid 333264562Sgshapiro equate name. 333364562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 333464562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 333564562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 333664562Sgshapiro mailer to return after sending all data to it. 333764562Sgshapiro Only free memory from the process list when adding a new process 333864562Sgshapiro into a previously filled slot. Previously, the memory was 333964562Sgshapiro freed at removal time. Since removal can happen in a 334064562Sgshapiro signal handler, this may leave the memory map in an 334164562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 334264562Sgshapiro David Cooley of Colby College. 334364562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 334464562Sgshapiro local users in the passwd file. The UserDB code has 334564562Sgshapiro already decided the message will be passed to another host 334664562Sgshapiro for processing. Fix from Tony Landells of Burdett 334764562Sgshapiro Buckeridge Young Limited. 334864562Sgshapiro Support LDAP authorization via either a file containing the 334964562Sgshapiro password or Kerberos V4 using the new map options 335064562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 335164562Sgshapiro distinguished_name is who to login as. The method can be 335264562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 335364562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 335464562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 335564562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 335664562Sgshapiro of Stanford University. 335764562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 335864562Sgshapiro deprecated and will be removed in a future version. 335964562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 336064562Sgshapiro and the map has the column delimiter set, it turns that 336164562Sgshapiro response into a delimiter separated string. The LDAP map 336264562Sgshapiro will traverse multiple entries as well. LDAP alias maps 336364562Sgshapiro automatically set the column delimiter to the comma. 336464562Sgshapiro Based on patch from Booker Bense of Stanford University and 336564562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 336664562Sgshapiro Support return of multiple values for a single LDAP lookup. The 336764562Sgshapiro values to be returned should be in a comma separated string. 336864562Sgshapiro For example, `-v "email,emailother"'. Patch from 336964562Sgshapiro Curtis W. Hillegas of Princeton University. 337064562Sgshapiro Allow the use of LDAP for alias maps. 337164562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 337264562Sgshapiro attributes found in the match will be returned. 337364562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 337464562Sgshapiro breaking up a single entry into multiple entries. This is 337564562Sgshapiro needed for LDAP alias file specifications to allow for 337664562Sgshapiro comma separated key and value strings. 337764562Sgshapiro Keep connections to LDAP server open instead of opening and closing 337864562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 337964562Sgshapiro connections such that multiple maps which use the same 338064562Sgshapiro host, port, bind DN, and authentication will only result in 338164562Sgshapiro a single connection to that host. 338264562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 338364562Sgshapiro Be more careful about checking for errors and freeing memory on 338464562Sgshapiro LDAP lookups. 338564562Sgshapiro Use asynchronous LDAP searches to save memory and network 338664562Sgshapiro resources. 338764562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 338864562Sgshapiro Increase portability to the Netscape LDAP libraries. 338964562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 339064562Sgshapiro replaced with the literal contents of the map lookup key -- 339164562Sgshapiro note that this means a lookup can be done using the LDAP 339264562Sgshapiro special characters. The new '%0' token can be used instead 339364562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 339464562Sgshapiro For example, if the LDAP map specification contains '-k 339564562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 339664562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 339764562Sgshapiro user attribute. Instead, if the LDAP map specification 339864562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 339964562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 340064562Sgshapiro with the name "*". 340164562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 340264562Sgshapiro more than one is returned, it is equivalent to no records 340364562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 340464562Sgshapiro alias dereference option; "-Z size" limits the number of 340564562Sgshapiro matches to return. 340664562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 340764562Sgshapiro LDAP maps. The value should only contain LDAP specific 340864562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 340964562Sgshapiro settings will be used for all LDAP maps unless they are 341064562Sgshapiro specified in the individual map specification ('K' 341164562Sgshapiro command). This option should be set before any LDAP maps 341264562Sgshapiro are defined. 341364562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 341464562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 341564562Sgshapiro Tech. 341664562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 341764562Sgshapiro particular, class entries get much smaller, which can be 341864562Sgshapiro important if you have large classes. 341964562Sgshapiro On network-related temporary failures, record the hostname which 342064562Sgshapiro gave error in the queued status message. Requested by 342164562Sgshapiro Ulrich Windl of the Universitat Regensburg. 342264562Sgshapiro Add new F=% mailer flag to allow for a store and forward 342364562Sgshapiro configuration. Mailers which have this flag will not attempt 342471345Sgshapiro delivery on initial receipt of a message or on queue runs 342564562Sgshapiro unless the queued message is selected using one of the 342664562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 342764562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 342864562Sgshapiro New option ControlSocketName which, when set, creates a daemon 342964562Sgshapiro control socket. This socket allows an external program to 343064562Sgshapiro control and query status from the running sendmail daemon 343164562Sgshapiro via a named socket, similar to the ctlinnd interface to the 343264562Sgshapiro INN news server. Access to this interface is controlled by 343364562Sgshapiro the UNIX file permissions on the named socket on most UNIX 343464562Sgshapiro systems (see sendmail/README for more information). An 343564562Sgshapiro example control program is provided as contrib/smcontrol.pl. 343664562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 343764562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 343864562Sgshapiro number of processors online on the system (if that can be 343964562Sgshapiro determined). For single processor machines, this change 344064562Sgshapiro has no effect. 344164562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 344264562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 344364562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 344464562Sgshapiro Motonori Nakamura of Kyoto University. 344564562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 344664562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 344764562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 344864562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 344964562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 345064562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 345164562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 345264562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 345364562Sgshapiro connection-based denial of service attacks. 345464562Sgshapiro Log basic information about authenticated connections at LogLevel 345564562Sgshapiro 10 or higher. 345664562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 345764562Sgshapiro information (from= syslog line). 345864562Sgshapiro Log the DSN code for each recipient if one is available as a new 345964562Sgshapiro equate (dsn=). 346064562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 3461120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 3462120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 3463120256Sgshapiro of the University of Illinois at Urbana-Champaign. 346464562Sgshapiro Detect temporary lookup failures in the host map if looking up a 346564562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 346664562Sgshapiro Finnish Meteorological Institute. 346764562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 346864562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 346964562Sgshapiro When a forward file points to an alias which runs a program, run 347064562Sgshapiro the program as the default user and the default group, not 347164562Sgshapiro the forward file user. This change also assures the 347264562Sgshapiro :include: directives in aliases are also processed using 347364562Sgshapiro the default user and group. Problem noted by Sergiu 347464562Sgshapiro Popovici of DNT Romania. 347564562Sgshapiro Prevent attempts to save a dead.letter file for a user with 347664562Sgshapiro no home directory (/no/such/directory). Problem noted by 347764562Sgshapiro Michael Brown of Finnigan FT/MS. 347864562Sgshapiro Include message delay and number of tries when logging that a 347964562Sgshapiro message has been completely delivered (LogLevel of 10 or 348064562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 348164562Sgshapiro Log the sender of a message even if none of the recipients were 348264562Sgshapiro accepted. If some of the recipients were rejected, it is 348364562Sgshapiro helpful to know the sender of the message. 348464562Sgshapiro Check the root directory (/) when checking a path for safety. 348564562Sgshapiro Problem noted by John Beck of Sun Microsystems. 348664562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 348764562Sgshapiro interactive and delivering to an alias which resolves to 348864562Sgshapiro multiple files. 348964562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 349064562Sgshapiro greater (see below); the help function doesn't print the 349164562Sgshapiro version of sendmail any longer, instead it is placed in 349264562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 349364562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 349464562Sgshapiro skipped and a version line (#vers) is introduced. The 349564562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 349664562Sgshapiro version is found, a warning is logged. The '#vers' 349764562Sgshapiro directive should be placed at the top of the help file. 349864562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 349964562Sgshapiro disk succeeded. Suggested by Nick Christenson. 350064562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 350164562Sgshapiro length before the attempt. 350264562Sgshapiro If a forward points to a filename for delivery, change to the 350364562Sgshapiro user's uid before checking permissions on the file. This 350464562Sgshapiro allows delivery to files on NFS mounted directories where 350564562Sgshapiro root is remapped to nobody. Problem noted by Harald 350664562Sgshapiro Daeubler of Universitaet Ulm. 350764562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 350864562Sgshapiro host status files, not all files. 350964562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 351064562Sgshapiro in the queue file for the message and set when delivery 351164562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 351264562Sgshapiro Wonderworks Inc. 351364562Sgshapiro Add support for storing information between rulesets using the new 351464562Sgshapiro macro map class. This can be used to store information 351564562Sgshapiro between queue runs as well using $={persistentMacros}. 351664562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 351764562Sgshapiro of Hannover. 351864562Sgshapiro New map class arith to allow for computations in rules. The 351964562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 352064562Sgshapiro as key. The two operands are specified as arguments; the 352164562Sgshapiro lookup returns the result of the computation. For example, 352264562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 352364562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 352464562Sgshapiro Add new syntax for header declarations which decide whether to 352564562Sgshapiro include the header based on a macro rather than a mailer 352664562Sgshapiro flag: 352764562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 352864562Sgshapiro This should be used along with $={persistentMacros}. 352964562Sgshapiro It can be used for adding headers to a message based on 353064562Sgshapiro the results of check_* and header check rulesets. 353164562Sgshapiro Allow new named config file rule check_eoh which is called after 353264562Sgshapiro all of the headers have been collected. The input to the 353364562Sgshapiro ruleset the number of headers and the size of all of the 353464562Sgshapiro headers in bytes separated by $|. This ruleset along with 353564562Sgshapiro the macro storage map can be used to correlate information 353664562Sgshapiro gathered between headers and to check for missing headers. 353764562Sgshapiro See cf/README or doc/op/op.ps for an example. 353864562Sgshapiro Change the default for the MeToo option to True to correspond 353964562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 354064562Sgshapiro option is deprecated and will be removed from a future 354164562Sgshapiro version. 354264562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 354364562Sgshapiro Change the sendmail binary default for SuperSafe to True. 354464562Sgshapiro Display ruleset names in debug and address test mode output 354564562Sgshapiro if referencing a named ruleset. 354664562Sgshapiro New mailer equate m= which will limit the number of messages 354764562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 354864562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 354964562Sgshapiro using it to sort. Now all the same domains are really run 355064562Sgshapiro through the queue together. If they have the same MX host, 355164562Sgshapiro then they will have a much better opportunity to use the 355264562Sgshapiro connection cache if available. This should be a reasonable 355364562Sgshapiro performance improvement. Patch from Randall Winchester of 355464562Sgshapiro the University of Maryland. 355564562Sgshapiro If a message is rejected by a header check ruleset, log who would 355664562Sgshapiro have received the message if it had not been rejected. 355764562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 355864562Sgshapiro queue immediately. No delivery attempt is made. 355964562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 356064562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 356164562Sgshapiro COMMANDS). 356264562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 356364562Sgshapiro but for outgoing connections. 356464562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 356564562Sgshapiro error messages and logging) and Modifiers, i.e. 356664562Sgshapiro a require authentication 356764562Sgshapiro b bind to interface through which mail has 356864562Sgshapiro been received 356964562Sgshapiro c perform hostname canonification 357064562Sgshapiro f require fully qualified hostname 357164562Sgshapiro h use name of interface for outgoing HELO 357264562Sgshapiro command 357364562Sgshapiro C don't perform hostname canonification 357464562Sgshapiro E disallow ETRN (see RFC 2476) 357564562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 357664562Sgshapiro h use name of interface for HELO command 357764562Sgshapiro The version number for queue files (qf) has been incremented to 4. 357864562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 357964562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 358064562Sgshapiro Institutes of Health. 358164562Sgshapiro If a mailer dies, print the status in decimal instead of octal 358264562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 358364562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 358464562Sgshapiro Move message priority from sender to recipient logging. Suggested by 358564562Sgshapiro Ulrich Windl of the Universitat Regensburg. 358664562Sgshapiro Add support for Berkeley DB 3.X. 358764562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 358864562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 358964562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 359064562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 359164562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 359264562Sgshapiro sub-options is set on the command line. Problem noted by 359364562Sgshapiro Graeme Hewson of Oracle. 359464562Sgshapiro Randomize equal preference MX records each time delivery is 359564562Sgshapiro attempted via a new connection to a host instead of once per 359664562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 359764562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 359864562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 359964562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 360064562Sgshapiro to hosts which have dynamically assigned names. 360164562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 360264562Sgshapiro the bounce for the same reason. If the body is not 8-bit 360364562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 360464562Sgshapiro not be included in the bounce. Problem noted by Valdis 360564562Sgshapiro Kletnieks of Virginia Tech. 360664562Sgshapiro The timeout for sending a message via SMTP has been changed from 360764562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 360864562Sgshapiro simply checks for progress on sending data every 5 minutes. 360964562Sgshapiro This will detect the inability to send information quicker 361064562Sgshapiro and reduce the number of processes simply waiting to 361164562Sgshapiro timeout. 361264562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 361364562Sgshapiro interface address structure when loading the system network 361464562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 361564562Sgshapiro Nanoteq. 361664562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 361764562Sgshapiro indicates the number of interfaces to read when probing 361864562Sgshapiro for hostnames and IP addresses for class w ($=w). The 361964562Sgshapiro default value is 512. Based on idea from Reinier 362064562Sgshapiro Bezuidenhout of Nanoteq. 362164562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 362264562Sgshapiro on load average. 362364562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 362464562Sgshapiro Northern Illinois University. 362564562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 362664562Sgshapiro envelope splitting has occurred. 362764562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 362864562Sgshapiro Luke Mewburn from RMIT University. 362964562Sgshapiro Add a "/quit" command to address test mode. 363064562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 363164562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 363264562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 363364562Sgshapiro Institute. 363464562Sgshapiro The contents of a class can now be copied to another class using 363564562Sgshapiro the syntax: "C{Dest} $={Source}".

Problem noted by Per 373364562Sgshapiro Hedeland of Ericsson. 373464562Sgshapiro mailq displays unprintable characters in addresses as their octal 373564562Sgshapiro representation and a leading backslash. This avoids problems 373664562Sgshapiro with "unprintable" characters. Problem noted by Michal 373764562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 373864562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 373964562Sgshapiro one character past the limit. This would cause subsequent 374064562Sgshapiro hops to break the line again. The '!' is now placed in 374164562Sgshapiro the last column of the limit if the line needs to be broken. 374264562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 374364562Sgshapiro from Per Hedeland of Ericsson. 374464562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 374564562Sgshapiro resolver will fall back to TCP. However, some 374664562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 374764562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 374864562Sgshapiro don't fail on ANY queries. 374964562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 375064562Sgshapiro address, do not send an empty postmaster notification DSN 375164562Sgshapiro to the postmaster.

Based on an idea from Neil Rickert 394064562Sgshapiro of Northern Illinois University. 394164562Sgshapiro CONFIG: If `canonify_hosts' is specified as parameter for 394264562Sgshapiro FEATURE(`nocanonify') then addresses which have only 394364562Sgshapiro a hostname, e.g., <user@host>, will be canonified. 394464562Sgshapiro CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is 394564562Sgshapiro nevertheless added to addresses with more than one component 394664562Sgshapiro in it. 394764562Sgshapiro CONFIG: Canonification is no longer attempted for any host or domain 394864562Sgshapiro in class 'P' ($=P). 394964562Sgshapiro CONFIG: New class for matching virtusertable entries $={VirtHost} that 395064562Sgshapiro can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE. 395164562Sgshapiro FEATURE(`virtuser_entire_domain') can be used to apply this 395264562Sgshapiro class also to entire subdomains. Hosts in this class are 395364562Sgshapiro treated as canonical in SCanonify2, i.e., a trailing dot 395464562Sgshapiro is added. 395564562Sgshapiro CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used, 395664562Sgshapiro include $={VirtHost} in $=R (hosts allowed to relay). 395764562Sgshapiro CONFIG: FEATURE(`generics_entire_domain') can be used to apply the 395864562Sgshapiro genericstable also to subdomains of $=G. 395964562Sgshapiro CONFIG: Pass "+detail" as %2 for virtusertable lookups. 396064562Sgshapiro Patch from Noam Freedman from University of Chicago. 396164562Sgshapiro CONFIG: Pass "+detail" as %1 for genericstable lookups. Suggested 396264562Sgshapiro by Raymond S Brand of rsbx.net. 396364562Sgshapiro CONFIG: Allow @domain in genericstable to override masquerading. 396464562Sgshapiro Suggested by Owen Duffy from Owen Duffy & Associates. 396564562Sgshapiro CONFIG: LOCAL_DOMAIN() adds entries to class w. Suggested by Steve 396664562Sgshapiro Hubert of University of Washington. 396764562Sgshapiro CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as 396864562Sgshapiro GNU is now the canonical system name. From Mark 396964562Sgshapiro Kettenis of the University of Amsterdam. 397064562Sgshapiro CONFIG: OSTYPE(`unixware7') updates from Larry Rosenman. 397164562Sgshapiro CONFIG: Do not include '=' in option expansion if there is no value 397264562Sgshapiro associated with the option.

Prindeville of Enteka Enterprise Technology 397664562Sgshapiro Services. 397764562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 397864562Sgshapiro names. Problem noted by Randall Winchester of Swales 397964562Sgshapiro Aerospace. 398064562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 398164562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 398264562Sgshapiro University and Brian Candler. 398364562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 398464562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 398564562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 398664562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 398764562Sgshapiro Institute. 398864562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 398964562Sgshapiro i.e., to set, add, or delete flags. 399064562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 399164562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 399264562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 399364562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 399464562Sgshapiro after check_rcpt and allows for exceptions from the checks. 399564562Sgshapiro CONFIG: Map declarations have been moved into their associated 399664562Sgshapiro feature files to allow greater flexibility in use of 399764562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 399864562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 399964562Sgshapiro line string for the local mailer. Requested by Il Oh of 400064562Sgshapiro Willamette Industries, Inc. 400164562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 400264562Sgshapiro converted to <user@d> 400364562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 400464562Sgshapiro Sun's older, broken configuration files. 400564562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 400664562Sgshapiro normal configuration, allowing anti-spam checks to be 400764562Sgshapiro performed. 400864562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 400964562Sgshapiro ${client_name} can't be resolved just temporarily. 401064562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 401164562Sgshapiro Institute. 401264562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 401364562Sgshapiro be accessed by their numbers). 401464562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 401564562Sgshapiro which describes whether to disallow "!" in the local part 401664562Sgshapiro of an address. 401764562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 401864562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 401964562Sgshapiro set. If the ruleset returns a mailer, the appropriate 402064562Sgshapiro action is taken, otherwise the returned tokens are ignored. 402164562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 402264562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 402364562Sgshapiro The latter is kept around for backward compatibility. 402464562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 402564562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 402664562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 402764562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 402864562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 402964562Sgshapiro Institute. 403064562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 403164562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 403264562Sgshapiro arguments overriding the mailer program, arguments, and 403364562Sgshapiro mailer definition flags. This makes it possible to use 403464562Sgshapiro other programs such as maildrop for local delivery. 403564562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 403664562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 403764562Sgshapiro Patch from Richard A. Nelson of IBM. 403864562Sgshapiro CONFIG: Add SMTP Authentication information to Received: header 403964562Sgshapiro default value (confRECEIVED_HEADER). 404064562Sgshapiro CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a 404164562Sgshapiro local mailer. Problem noted by Per Hedeland of Ericsson. 404264562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 404364562Sgshapiro University of California at Berkeley. 404464562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of 404564562Sgshapiro Illinois at Urbana-Champaign. 404664562Sgshapiro CONTRIB: etrn.pl now recognizes bogus host names. Patch from 404764562Sgshapiro Bruce Barnett of GE's R&D Lab. 404864562Sgshapiro CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle 404964562Sgshapiro Corporation UK. 405064562Sgshapiro CONTRIB: Added qtool.pl to assist in managing the queues. 405164562Sgshapiro DEVTOOLS: Prevent user environment variables from interfering with 405264562Sgshapiro the Build scripts. Problem noted by Ezequiel H. Panepucci of 405364562Sgshapiro Yale University. 405464562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 405564562Sgshapiro be used for building. 405664562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 405764562Sgshapiro used for a fresh build. 405864562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 405964562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 406064562Sgshapiro ranlib. 406164562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 406264562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 406364562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 406464562Sgshapiro building of the man pages when defined. Suggested by Bryan 406564562Sgshapiro Costales. 406664562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 406764562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 406864562Sgshapiro installation of the sendmail helpfile and statistics file 406964562Sgshapiro respectively. Suggested by Bryan Costales. 407064562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 407164562Sgshapiro of Siemens Business Services. 407264562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 407364562Sgshapiro stdio library. The new buffered file I/O depends on the 407464562Sgshapiro Torek stdio library. This option can be either portable or 407564562Sgshapiro torek. 407664562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 407764562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 407864562Sgshapiro They should contain the C source files for the object files 407964562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 408064562Sgshapiro will be passed to the 'make depend' stage of compilation. 408164562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 408264562Sgshapiro in the sendmail distribution. Each has the form 408364562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 408464562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 408564562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 408664562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 408764562Sgshapiro building the distribution, but documentation on the changes 408864562Sgshapiro are in devtools/README. 408964562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 409064562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 409164562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 409264562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 409364562Sgshapiro new variable which identifies the root of the source 409464562Sgshapiro directories for all of the programs in the distribution. 409564562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 409664562Sgshapiro time. They can both still be overridden by setting the m4 409764562Sgshapiro macro. 409864562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 409964562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 410064562Sgshapiro build configurations, and places objects in obj.prefix.*/. 410164562Sgshapiro Complains as 'Build -f file' does for existing object 410264562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 410364562Sgshapiro Corporation. 410464562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 410564562Sgshapiro manual pages in the directory tree specified by 410664562Sgshapiro confMANROOTMAN. 410764562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 410864562Sgshapiro preformatted pages from the distribution. The new variable 410964562Sgshapiro confCOPY specifies the copying program. 411064562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 411164562Sgshapiro question. Suggested by Terry Lambert of Whistle 411264562Sgshapiro Communications. 411364562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 411464562Sgshapiro of the installed statistics and help files, respectively. 411564562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 411664562Sgshapiro operating system identity. Problem noted by Erik 411764562Sgshapiro Wachtenheim of Dartmouth College. 411864562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 411964562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 412064562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 412164562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 412264562Sgshapiro how to strip binaries. These are used by the new 412364562Sgshapiro install-strip target. 412464562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 412564562Sgshapiro the others (if it exists). 412664562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 412764562Sgshapiro then the default ones. 412890792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 412964562Sgshapiro as local delivery agent without LMTP mode, use 413064562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 413164562Sgshapiro to set the S flag. 413264562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 413364562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 413464562Sgshapiro Northern Illinois University. 413564562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 413664562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 413764562Sgshapiro the Finnish Meteorological Institute. 413864562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 413964562Sgshapiro MAILLOCK when compiling. Also requires linking with 414064562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 414164562Sgshapiro University. 414264562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 414364562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 414464562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 414564562Sgshapiro University. 414664562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 414764562Sgshapiro structure to the beginning of the program. This ensures that 414864562Sgshapiro the getservbyname() is done before any seteuid to a possibly 414964562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 415064562Sgshapiro on a Solaris system, this avoids syslog messages such as, 415164562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 415264562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 415364562Sgshapiro University. 415464562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 415564562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 415664562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 415764562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 415864562Sgshapiro characters (in LMTP mode), mail.local split the incoming 415964562Sgshapiro line up into 2046-character output lines (excluding the 416064562Sgshapiro newline). If an input line was 2047 characters long 416164562Sgshapiro (excluding CR-LF) and the last character was a '.', 416264562Sgshapiro mail.local saw it as the end of input, transfered it to the 416364562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 416464562Sgshapiro If the message was much longer, both sendmail and 416564562Sgshapiro mail.local would deadlock waiting for each other to read 416664562Sgshapiro what they have written. Problem noted by Peter Jeremy of 416764562Sgshapiro Alcatel Australia Limited. 416864562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 416964562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 417064562Sgshapiro Neil Rickert of Northern Illinois University. 417164562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 417264562Sgshapiro timeout to avoid starvation. 417364562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 417464562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 417564562Sgshapiro Infinite Monkeys & Co. 417664562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 417764562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 417864562Sgshapiro printed in a machine readable fashion and the stats file 417964562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 418064562Sgshapiro of Maryland. 418164562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 418264562Sgshapiro generated maps to the TrustedUser as specified in the 418364562Sgshapiro sendmail configuration file. 418464562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 418564562Sgshapiro configuration file to use for finding the TrustedUser 418664562Sgshapiro option. 418764562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 418864562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 418964562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 419064562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 419164562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 419264562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 419364562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 419464562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 419564562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 419664562Sgshapiro Corporation UK. 419764562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 419864562Sgshapiro (e.g., sendmail would not drop root privileges if the 419964562Sgshapiro option was specified on the command line). Problem noted 420064562Sgshapiro by Todd C. Miller of Courtesan Consulting. 420164562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 420264562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 420364562Sgshapiro Institute for Global Communications. 420464562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 420564562Sgshapiro alias file(s) if the -f option is not used. Patch from 420664562Sgshapiro John Beck of Sun Microsystems. 420764562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 420864562Sgshapiro configuration file to use for finding alias file(s). Patch 420964562Sgshapiro from John Beck of Sun Microsystems. 421064562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 421164562Sgshapiro lists using || and &&.

Sites 465838032Speter which need the ability to override security can use the 465938032Speter DontBlameSendmail option. See the README file for more 466038032Speter information. 466138032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 466238032Speter if maps or alias files are in world writable directories. 466338032Speter This fixes the change added to 8.8.6 to prevent links in these 466438032Speter world writable directories. 466538032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 466638032Speter it is in a world writable directory. 466738032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 466838032Speter tty it may be able to push bytes back to the senders input. 466938032Speter Unfortunately this breaks -v mode.

After this number is reached, sendmail 472938032Speter starts returning "452 Too many recipients" to all RCPT 473038032Speter commands. This can be used to limit the number of recipients 473138032Speter per envelope (in particular, to discourage use of the server 473238032Speter for spamming). Note: a better approach is to restrict 473338032Speter relaying entirely. 473438032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 473538032Speter to ldapx map and added timeout for ldap_open call to 473638032Speter avoid hanging sendmail in the event of hung LDAP servers. 473738032Speter Patch from Booker Bense of Stanford University. 473838032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 475738032Speter of Procter & Gamble. 475838032Speter The LDAP map -s flag was not properly parsed and the error message 475964562Sgshapiro given included the remainder of the arguments instead of 476038032Speter solely the argument in error. Problem noted by Aidan Nichol 476138032Speter of Procter & Gamble. 476238032Speter New DontBlameSendmail option. This option allows administrators to 476338032Speter bypass some of sendmail's file security checks at the expense 476438032Speter of system security.

In particular, if you 480038032Speter have lots of virtual interfaces, this option will speed up 480138032Speter startup. However, unless you make other arrangements, mail 480238032Speter sent to those addresses will be bounced. 480338032Speter Automatically create alias databases if they don't exist and 480438032Speter AutoRebuildAliases is set. 480538032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 480638032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 480738032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 480838032Speter When determining the client host name ($&{client_name} macro), do 480938032Speter a forward (A) DNS lookup on the result of the PTR lookup 481038032Speter and compare results. If they differ or if the PTR lookup 481138032Speter fails, &{client_name} will contain the IP address 481264562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 481338032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 481438032Speter (i.e, it is like -ax for the temporary failure case, in 481538032Speter contrast to the success case). 481638032Speter New syntax to do limited checking of header syntax. A config line 481738032Speter of the form: 481838032Speter HHeader: $>Ruleset 481938032Speter causes the indicated Ruleset to be invoked on the Header 482038032Speter when read. This ruleset works like the check_* rulesets -- 482138032Speter that is, it can reject mail on the basis of the contents. 482238032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 482338032Speter from hiding their connection information in Received: 482438032Speter headers. 482538032Speter When SingleThreadDelivery is active, deliveries to locked hosts 482638032Speter are skipped. This will cause the delivering process to 482738032Speter try the next MX host or queue the message if no other MX 482838032Speter hosts are available. Suggested by Alexander Litvin. 482938032Speter The [FILE] mailer type now delivers to the file specified in the 483038032Speter A= equate of the mailer definition instead of $u. It also 483138032Speter obeys all of the F= mailer flags such as the MIME 483238032Speter 7/8 bit conversion flags. This is useful for defining 483338032Speter a mailer which delivers to the same file regardless of the 483464562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 483538032Speter Do not assume the identity of a remote connection is root@localhost 483638032Speter if the remote connection closes the socket before the 483738032Speter remote identity can be queried. 483838032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 483938032Speter Some mailers, including procmail, require that the real 484038032Speter uid is left unchanged by sendmail. Problem noted by Per 484138032Speter Hedeland of Ericsson. 484238032Speter No longer is the src/obj*/Makefile selected from a large list -- it 484338032Speter is now generated using the information in BuildTools/OS/ -- 484438032Speter some of the details are determined dynamically via 484538032Speter BuildTools/bin/configure.sh. 484638032Speter The other programs in the sendmail distribution -- mail.local, 484738032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 484838032Speter the new Build method which creates an operating system 484938032Speter specific Makefile using the information in BuildTools. 485038032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 485138032Speter a failure on one message won't affect future messages to the 485238032Speter same host). This is necessary if the remote host sends 485338032Speter a 451 error if the domain of the sender does not resolve 485438032Speter as is common in anti-spam configurations. Problem noted 485538032Speter by Mitchell Blank Jr of Exec-PC. 485638032Speter New "discard" mailer for check_* rulesets and header checking 485738032Speter rulesets. If one of the above rulesets resolves to the 485838032Speter $#discard mailer, the commands will be accepted but the 485938032Speter message will be completely discarded after it is accepting. 486038032Speter This means that even if only one of the recipients 486138032Speter resolves to the $#discard mailer, none of the recipients 486238032Speter will receive the mail. Suggested by Brian Kantor. 486338032Speter All but the last cloned envelope of a split envelope were queued 486438032Speter instead of being delivered.

Problem noted by 489838032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 489938032Speter Include a magic number and version in the StatusFile for the 490038032Speter mailstats command. 490138032Speter Record the number of rejected and discarded messages in the 490238032Speter StatusFile for display by the mailstats command. Patch 490338032Speter from Randall Winchester of the University of Maryland. 490438032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 490538032Speter user portion as IDENT:username@site instead of 490638032Speter username@site to differentiate the two. Suggested by 490738032Speter Kari Hurtta of the Finnish Meteorological Institute. 490838032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 490938032Speter Ericsson. 491038032Speter Change persistent host status filename substitution so '/' is 491138032Speter replaced by ':' instead of '|' to avoid clashes. Also 491238032Speter avoid clashes with hostnames with leading dots. Fix from 491338032Speter Mitchell Blank Jr. of Exec-PC. 491438032Speter If the system lock table is full, only attempt to create a new 491538032Speter queue entry five times before giving up. Previously, it 491638032Speter was attempted indefinitely which could cause the partition 491738032Speter to run out of inodes. Problem noted by Suzie Weigand of 491838032Speter Stratus Computer, Inc. 491938032Speter In verbose mode, warn if the sendmail.cf version is less than the 492038032Speter currently supported version. 492138032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 492238032Speter from Randall S. Winchester of the University of Maryland. 492338032Speter Properly quote a full name passed via the -F command line option, 492438032Speter the Full-Name: header, or the NAME environment variable if 492538032Speter it contains characters which must be quoted. Problem noted 492638032Speter by Kari Hurtta of the Finnish Meteorological Institute. 492738032Speter Avoid possible race condition that unlocked a mail job before 492838032Speter releasing the transcript file on systems that use flock(2). 492938032Speter In some cases, this might result in a "Transcript Unavailable" 493038032Speter message in error bounces. 493138032Speter Accept SMTP replies which contain only a reply code and no 493238032Speter accompanying text. Problem noted by Fernando Fraticelli of 493338032Speter Digital Equipment Corporation. 493438032Speter Portability: 493538032Speter AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura 493638032Speter of Kyoto University. 493738032Speter AIX 4.2 requires <userpw.h> before <usersec.h>.

From Guillermo Freige of 495838032Speter Gobernacion de la Pcia de Buenos Aires and Paul 495938032Speter Fischer of BTG, Inc. 496038032Speter SunOS 4.X does not include memmove(). Patch from 496138032Speter Per Hedeland of Ericsson. 496238032Speter SunOS 5.7 includes getloadavg() function for determining 496338032Speter load average. Patch from John Beck of Sun 496438032Speter Microsystems. 496538032Speter CONFIG: Increment version number of config file. 496638032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 496738032Speter map for the various maps. The default is hash. Patch from 496838032Speter Robert Harker of Harker Systems. 496938032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 497038032Speter directory for certain programs. 497138032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 497238032Speter local mail delivery. By the default, /usr/libexec/mail.local 497338032Speter is used. This is expected to be the mail.local shipped 497438032Speter with 8.9 which is LMTP capable. The path is based on the 497538032Speter new confEBINDIR m4 variable. 497638032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 497738032Speter FEATURE(smrsh). Note that this changes the default from 497838032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 497938032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 498038032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 498138032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 498238032Speter the user to setup different .forward files for 498338032Speter user+detail addressing. 498438032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 498538032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 498638032Speter DontProbeInterfaces, and DontBlameSendmail options. 498738032Speter CONFIG: by default do not allow relaying (that is, accepting mail 498838032Speter from outside your domain and sending it to another host 498938032Speter outside your domain). 499038032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 499138032Speter any site to any site. 499238032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 499338032Speter domain as defined by the 'm' class ($=m) to relay. 499438032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 499538032Speter the MX records of the host portion of an incoming recipient. 499638032Speter CONFIG: new FEATURE(access_db) which turns on the access database 499777349Sgshapiro feature. This database gives you the ability to allow 499838032Speter or refuse to accept mail from specified domains for 499938032Speter administrative reasons. By default, names that are listed 500038032Speter as "OK" in the access db are domain names, not host names. 500138032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 500238032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 500338032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 500438032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 500538032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 500638032Speter of FEATURE(access_db) and class 'R' to lookup individual 500738032Speter host names only. 500838032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 500938032Speter using % addressing is used, e.g. user%site@othersite, 501038032Speter and othersite is in class 'R', the check_rcpt ruleset 501138032Speter will strip @othersite and recheck user@site for relaying. 501238032Speter This feature changes that behavior. It should not be 501338032Speter needed for most installations. 501438032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 501538032Speter domain portion of the mail sender is a local host. This 501638032Speter should only be used if absolutely necessary as it opens 501738032Speter a window for spammers. Patch from Randall S. Winchester of 501838032Speter the University of Maryland. 501938032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 502038032Speter block incoming mail destined for certain recipient 502138032Speter usernames, hostnames, or addresses. 502238032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 502338032Speter refused if the host part of the argument to MAIL FROM: cannot 502438032Speter be located in the host name service (e.g., DNS). 502538032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 502638032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 502738032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 502838032Speter MAIL FROM: senders which do not include a domain. 502938032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 503038032Speter Realtime Blackhole List. You can specify the RBL name 503138032Speter server to contact by specifying it as an optional argument. 503238032Speter The default is rbl.maps.vix.com. For details, see 503338032Speter http://maps.vix.com/rbl/. 503438032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 503538032Speter Local_check_rcpt from check_relay, check_mail, and 503638032Speter check_rcpt. Users with local rulesets should place the 503738032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 503838032Speter returns $#OK, the message is accepted. If the ruleset 503938032Speter returns a mailer, the appropriate action is taken, else 504038032Speter the return of the ruleset is ignored. 504138032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 504238032Speter default to support file, :include:, and program deliveries. 504338032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 504438032Speter pick the proper default value. See the SECURITY note 504538032Speter above for more information. 504638032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 504738032Speter no-op. Patch from Kari Hurtta of the Finnish 504838032Speter Meteorological Institute. 504938032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 505038032Speter daemon since DEC's /bin/mail will drop the envelope 505138032Speter sender if run as mailnull. See the Digital UNIX section 505238032Speter of src/README for more information. Problem noted by 505338032Speter Kari Hurtta of the Finnish Meteorological Institute. 505438032Speter CONFIG: .cf files are now stored in the same directory with the 505538032Speter .mc files instead of in the obj directory. 505664562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 505738032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 505838032Speter setting SingleLineFromHeader, AllowBogusHELO, and 505938032Speter MustQuoteChars respectively. 506038032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This 506138032Speter SMTP-like protocol allows detailed reporting of delivery 506238032Speter status on a per-user basis. Code donated by John Myers of 506338032Speter CMU (now of Netscape). 506438032Speter MAIL.LOCAL: HP-UX support from Randall S. Winchester of the 506564562Sgshapiro University of Maryland. NOTE: mail.local is not 506638032Speter compatible with the stock HP-UX mail format. Be sure to 506738032Speter read mail.local/README. 506838032Speter MAIL.LOCAL: Prevent other mail delivery agents from stealing a 506938032Speter mailbox lock. Patch from Randall S.

Problem noted by Kari E. 519038032Speter Hurtta of the Finnish Meteorological Institute. 519138032Speter Ignore the debug resolver option unless using sendmail debug trace 519238032Speter option for resolver. Problem noted by Greg Nichols of Wind 519338032Speter River Systems. 519438032Speter If SingleThreadDelivery was enabled and the remote server returned a 519538032Speter protocol error on the DATA command, the connection would be 519638032Speter closed but the persistent host status file would not be 519738032Speter unlocked so other sendmail processes could not deliver to 519838032Speter that host. Problem noted by Peter Wemm of DIALix. 519938032Speter If queueing up a message due to an expensive mailer, don't increment 520038032Speter the number of delivery attempts or set the last delivery 520138032Speter attempt time so the message will be delivered on the next 520238032Speter queue run regardless of MinQueueAge. Problem noted by 520338032Speter Brian J. Coan of the Institute for Global Communications. 520438032Speter Authentication warnings of "Processed from queue _directory_" and 520538032Speter "Processed by _username_ with -C _filename_" would be logged 520638032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 520738032Speter of the Finnish Meteorological Institute. 520838032Speter Use a better heuristic for detecting GDBM. 520938032Speter Log null connections on dropped connections. Problem noted by 521038032Speter Jon Lewis of Florida Digital Turnpike. 521138032Speter If class dbm maps are rebuilt, sendmail will now detect this and 521238032Speter reopen the map. Previously, they could give stale 521338032Speter results during a single message processing (but would 521438032Speter recover when the next message was received). Fix from 521538032Speter Joe Pruett of Q7 Enterprises. 521638032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 521738032Speter requests. Problem noted by Kari E. Hurtta of the 521838032Speter Finnish Meteorological Institute. 521938032Speter Do not send a bounce message back to the sender regarding bad 522038032Speter recipients if the SMTP connection is dropped before the 522138032Speter message is accepted. Problem noted by Kari E. Hurtta of the 522238032Speter Finnish Meteorological Institute. 522338032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 522438032Speter sendmail via a UNIX pipe. This will allow rulesets using 522538032Speter $&{client_name} to process without sending the string through 522638032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 522738032Speter A combination of deferred delivery mode, a double bounce situation, 522838032Speter and the inability to save a bounce message to 522938032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 523038032Speter to postmaster but not remove the offending envelope from the 523138032Speter queue causing it to create a new bounce message each time the 523238032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 523338032Speter Associates. 523438032Speter Remove newlines from hostname information returned via DNS. There are 523538032Speter no known security implications of newlines in hostnames as 523638032Speter sendmail filters newlines in all vital areas; however, this 523738032Speter could cause confusing error messages. 523838032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 523938032Speter rejected if any of the specified addresses were bad. This 524038032Speter behavior was modified to only reject the bad addresses and not 524138032Speter the entire message.

From Tetsu Ushijima of the 536238032Speter Tokyo Institute of Technology. 536338032Speter Fix race condition that could cause the body of a message to be 536438032Speter lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of 536838032Speter Results Computing. 536938032Speter If a qf file was found in a mail queue directory that had a problem 537038032Speter (wrong ownership, bad format, etc.) and the file name was 537138032Speter exactly MAXQFNAME bytes long, then instead of being tried 537238032Speter once, it would be tried on every queue run. Problem noted 537338032Speter by Bryan Costales of Mercury Mail. 537438032Speter If the system supports an st_gen field in the status structure, 537538032Speter include it when reporting that a file has changed after open. 537638032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 537738032Speter This out to be checked as well as reported, since it is 537838032Speter theoretically possible for an attacker to remove a file after 537938032Speter it is opened and replace it with another file that has the 538038032Speter same i-number, but some filesystems (notably AFS) return 538138032Speter garbage in this field, and hence always look like the file 538238032Speter has changed. As a practical matter this is not a security 538338032Speter problem, since the files can be neither hard nor soft links, 538438032Speter and on no filesystem (that I am aware of) is it possible to 538538032Speter have two files on the same filesystem with the same i-number 538638032Speter simultaneously. 538738032Speter Delete the root Makefile from the distribution -- it is only for 538838032Speter use internally, and does not work at customer sites. 538938032Speter Fix botch that caused the second MAIL FROM: command in a single 539038032Speter transaction to clear the entire transaction.

This makes it possible to create a root 547638032Speter owned file in an arbitrary directory by inserting the symlink 547738032Speter into a writable directory after the initial lstat(2) check 547838032Speter determined that the file did not exist. The only verified 547938032Speter example of a system having these odd semantics for O_EXCL 548038032Speter and symbolic links was HP-UX prior to version 9.07. Most 548138032Speter systems do not have the problem, since a exclusive create 548238032Speter of a file disallows symbolic links. Systems that have been 548338032Speter verified to NOT have the problem include AIX 3.x, *BSD, 548438032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 548538032Speter and Ultrix. This is a potential exposure on systems that 548638032Speter have this bug and which do not have a MAILER-DAEMON alias 548738032Speter pointing at a legitimate account, since this will cause old 548838032Speter mail to be dropped in /var/tmp/dead.letter. 548938032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 549038032Speter if maps or alias files are in world writable directories. 549138032Speter If your system has alias maps in writable directories, it 549238032Speter is potentially possible for an attacker to replace the .db 549338032Speter (or .dir and .pag) files by symbolic links pointing at 549438032Speter another database; this can be used either to expose 549538032Speter information (e.g., by pointing an alias file at /etc/spwd.db 549638032Speter and probing for accounts), or as a denial-of-service attack 549738032Speter (by trashing the password database). The fix disallows 549838032Speter symbolic links entirely when rebuilding alias files or on 549938032Speter maps that are in writable directories, and always warns on 550038032Speter writable directories; 8.9 will probably consider writable 550138032Speter directories to be fatal errors. This does not represent an 550238032Speter exposure on systems that have alias files in unwritable 550338032Speter system directories. 550438032Speter SECURITY: disallow .forward or :include: files that are links (hard 550538032Speter or soft) if the parent directory (or any directory in the 550638032Speter path) is writable by anyone other than the owner. This is 550738032Speter similar to the previous case for user files. This change 550838032Speter should not affect most systems, but is necessary to prevent 550938032Speter an attacker who can write the directory from pointing such 551038032Speter files at other files that are readable only by the owner. 551138032Speter SECURITY: Tighten safechown rules: many systems will say that they 551238032Speter have a safe (restricted to root) chown even on files that 551338032Speter are mounted from another system that allows owners to give 551438032Speter away files. The new rules are very strict, trusting file 551538032Speter ownership only in those few cases where the system has 551638032Speter been verified to be at least as paranoid as necessary. 551738032Speter However, it is possible to relax the rules to partially 551838032Speter trust the ownership if the directory path is not world or 551938032Speter group writable. This might allow someone who has a legitimate 552038032Speter :include: file (referenced directly from /etc/aliases) to 552138032Speter become another non-root user if the :include: file is in a 552238032Speter non-writable directory on an NFS-mounted filesystem where 552338032Speter the local system says that giveaway is denied but it is 552438032Speter actually permitted. I believe this to be a very small set 552538032Speter of cases. If in doubt, do not point :include: aliases at 552638032Speter NFS-mounted filesystems. 552738032Speter SECURITY: When setting a numeric group id using the RunAsUser option 552838032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 552938032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 553038032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 553138032Speter The user id was still set properly. Problem noted by Uli 553238032Speter Pralle of the Technical University of Berlin. 553338032Speter Save the initial gid set for use when checking for if the 553438032Speter PrivacyOptions=restrictmailq option is set.

Patch 554138032Speter from Theo de Raadt. 554238032Speter The "Message is too large" error didn't successfully bounce the error 554338032Speter back to the sender.

Note that this should really 557538032Speter be fixed in the zone file for the domain. Problem noted by 557638032Speter Joe Rhett of Navigist, Inc. 557738032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 557838032Speter the message as having been tried; otherwise the next queue 557938032Speter run will not realize that this is a second attempt and will 558038032Speter retry immediately. Problem noted by Bryan Costales of 558138032Speter Mercury Mail. 558238032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 558338032Speter will be run until the later setting of the clock is reached. 558438032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 558538032Speter Morgan Stanley. 558638032Speter If the load average rises above the cutoff threshold (above which 558738032Speter sendmail will not process the queue at all) during a queue 558838032Speter run, abort the queue run immediately. Problem noted by 558938032Speter Bryan Costales of Mercury Mail. 559038032Speter The variable queue processing algorithm (based on the message size, 559138032Speter number of recipients, message precedence, and job age) was 559238032Speter non-functional -- either the entire queue was processed or 559338032Speter none of the queue was processed. The updated algorithm 559438032Speter does no queue run if a single recipient zero size job will 559538032Speter not be run. 559638032Speter If there is a fatal ("panic") message that will cause sendmail to 559738032Speter die immediately, never hold the error message for future 559838032Speter printing. 559938032Speter Force ErrorMode=print in -bt mode so that all errors are printed 560038032Speter regardless of the setting of the ErrorMode option in the 560138032Speter configuration file. Patch from Gregory Neil Shapiro. 560238032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 560338032Speter routine available in one of the libraries. Use it in conf.h. 560438032Speter The -m (match only) flag now works on host class maps. 560538032Speter If class hash or btree maps are rebuilt, sendmail will now detect 560638032Speter this and reopen the map. Previously, they could give 560738032Speter erroneous results during a single message processing 560838032Speter (but would recover when the next message was received). 560938032Speter Don't delete zero length queue files when doing queue runs until the 561038032Speter files are at least ten minutes old. This avoids a potential 561138032Speter race condition: the creator creates the qf file, getting back 561238032Speter a file descriptor. The queue runner locks it and deletes it 561338032Speter because it is zero length. The creator then writes the 561438032Speter descriptor that is now for a disconnected file, and the 561538032Speter job goes away. Based on a suggestion by Bryan Costales. 561638032Speter When determining the "validated" host name ($_ macro), do a forward 561738032Speter (A) DNS lookup on the result of the PTR lookup and compare 561838032Speter results. If they differ or if the PTR lookup fails, tag the 561938032Speter address as "may be forged". 562038032Speter Log null connections (i.e., hosts that connect but do not do any 562138032Speter substantive activity on the connection before disconnecting; 562238032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 562338032Speter Always permit "writes" to /dev/null regardless of the link count. 562438032Speter This is safe because /dev/null is special cased, and no open 562538032Speter or write is ever actually attempted. Patch from Villy Kruse 562638032Speter of TwinCom. 562738032Speter If a message cannot be sent because of a 552 (exceeded storage 562838032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 562938032Speter was given, don't return the body in the bounce, since there 563038032Speter is a very good chance that the message will double-bounce. 563138032Speter Fix possible line truncation if a quoted-printable had an =00 escape 563238032Speter in the body. Problem noted by Charles Karney of the Princeton 563338032Speter Plasma Physics Laboratory. 563438032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 563538032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 563638032Speter Institute. 563738032Speter The MaxDaemonChildren option wasn't applying to queue runs as 563838032Speter documented. Note that this increases the potential denial 563938032Speter of service problems with this option: an attacker can 564038032Speter connect many times, and thereby lock out queue runs as well 564138032Speter as incoming connections. If you use this option, you should 564238032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 564338032Speter to avoid this attack. Failure to limit noted by Matthew 564438032Speter Dillon of BEST Internet Communications. 564538032Speter Always give a message in newaliases if alias files cannot be 564638032Speter opened instead of failing silently. Suggested by Gregory 564738032Speter Neil Shapiro. This change makes the code match the O'Reilly 564838032Speter book (2nd edition). 564938032Speter Some older versions of the resolver could return with h_errno == -1 565038032Speter if no name server could be reached, causing mail to bounce 565138032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 565238032Speter John Beck of SunSoft. 565338032Speter If a :include: file is owned by a user that does not have an entry 565438032Speter in the passwd file, sendmail could dereference a null pointer. 565538032Speter Problem noted by Satish Mynam of Sun Microsystems. 565638032Speter Take precautions to make sure that the SMTP protocol cannot get out 565738032Speter of sync if (for example) an alias file cannot be opened. 565838032Speter Fix a possible race condition that can cause a SIGALRM to come in 565938032Speter immediately after a SIGHUP, causing the new sendmail to die. 566038032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 566138032Speter from Villy Kruse of TwinCom. 566238032Speter Ignore improperly formatted SMTP reply codes. Previously these were 566338032Speter partially processed, which could cause confusing error 566438032Speter returns. 566538032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 566638032Speter on some architectures. 566738032Speter Portability: 566838032Speter A/UX: from Jim Jagielski of NASA/GSFC. 566938032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 567038032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 567138032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 567238032Speter defined. Problem reported by A Sun of the University 567338032Speter of Washington. 567438032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 567538032Speter the system rather than guessing at compile time. 567638032Speter Patch contributed by John Beck of Sun Microsystems. 567738032Speter Intel Paragon: from Wendy Lin of Purdue University. 567838032Speter GNU Hurd: from Miles Bader of the GNU project. 567938032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 568038032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 568138032Speter Unfortunately releasing them opens a race condition, 568238032Speter but there appears to be no fix for this. Patch from 568338032Speter Gregory Neil Shapiro. 568438032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 568538032Speter Solaris: a bug in strcasecmp caused characters with the 568638032Speter high order bit set to apparently randomly match 568738032Speter letters -- for example, $| (0233) matches "i" and "I". 568838032Speter Problem noted by John Gregson of the University of 568938032Speter Cambridge. 569038032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 569138032Speter Kari Hurtta. 569238032Speter IRIX 6.x: Create Makefiles for systems that claim to be 569338032Speter IRIX64 but are 6.2 or higher (so use the regular 569438032Speter IRIX Makefile). 569538032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 569638032Speter Problem noted by Eric Hagberg of Morgan Stanley. 569738032Speter CONFIG: Some canonification was still done for UUCP-like addresses 569838032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 569938032Speter Brian Candler. 570038032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 570138032Speter local names as local. Problem noted by Jeff Polk of BSDI; 570238032Speter fix provided by Gregory Neil Shapiro. 570338032Speter CONFIG: The "local:user" syntax entries in mailertables and other 570438032Speter "mailer:user" syntax locations returned an incorrect value 570538032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 570638032Speter CONFIG: Retain "+detail" information when forwarding mail to a 570738032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 570838032Speter Guenther of Gustavus Adolphus College. 570938032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 571038032Speter rules are the same as for aliasing. Based on a patch from 571138032Speter Gregory Neil Shapiro. 571238032Speter CONFIG: Break up parsing rules into several pieces; this should 571338032Speter have no functional change in this release, but makes it 571438032Speter possible to have better anti-spam rulesets in the future. 571538032Speter CONFIG: Disallow double dots in host names to avoid having the 571638032Speter HostStatusDirectory store status under the wrong name. 571738032Speter In some cases this can be used as a denial-of-service attack. 571838032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 571938032Speter Gregory Neil Shapiro. 572038032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 572138032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 572238032Speter don't include From_, and convert to 8-bit). Suggestions 572338032Speter from Kimmo Suominen and Roderick Schertler. 572464562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 572538032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 572638032Speter was specified, even when it wasn't. 572738032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 572838032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 572938032Speter "slip in" a symbolic link between the lstat(2) call and the 573038032Speter exclusive open. This is only a problem on System V derived 573138032Speter systems that allow an exclusive create on files that are 573238032Speter symbolic links pointing nowhere. 573338032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 573438032Speter not reset back to root, which on some systems would cause 573538032Speter later mailboxes to fail. Also, any partial message would 573638032Speter not be truncated, which could result in repeated deliveries. 573738032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 573838032Speter developers). 573938032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 574038032Speter change to the sendmail map code was made in 8.8.3. Problem 574138032Speter noted by Gregory Neil Shapiro. 574238032Speter MAKEMAP: Give warnings on file problems such as map files that are 574390792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 574438032Speter often run as root and hence has the potential for the same 574538032Speter sorts of problems as alias rebuilds. 574638032Speter MAKEMAP: Change compilation so that it will link properly on 574738032Speter NEXTSTEP. 574838032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 574938032Speter Accept an optional list of arguments following the server 575038032Speter name for the ETRN arguments to use (instead of $=w). Other 575138032Speter miscellaneous bug fixes. From Christian von Roques via 575238032Speter John Beck of Sun Microsystems. 575338032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 575438032Speter Perl script converts GECOS information in the /etc/passwd 575538032Speter file into aliases, allowing for faster access to full name 575638032Speter lookups; it is also clever about adding aliases (to root) 575738032Speter for system accounts. 575838032Speter NEW FILES: 575938032Speter src/safefile.c 576038032Speter cf/ostype/gnuhurd.m4 576138032Speter cf/ostype/irix6.m4 576238032Speter contrib/passwd-to-alias.pl 576338032Speter src/Makefiles/Makefile.IRIX64.6.1 576438032Speter src/Makefiles/Makefile.IRIX64.6.x 576538032Speter RENAMED FILES: 576638032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 576738032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 576838032Speter 576964562Sgshapiro8.8.5/8.8.5 1997/01/21 577038032Speter SECURITY: Clear out group list during startup. Without this, sendmail 577138032Speter will continue to run with the group permissions of the caller, 577238032Speter even if RunAsUser is specified. 577338032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 577438032Speter to any known attack, but it's best to be conservative. 577538032Speter Suggested by Peter Wemm of DIALix. 577638032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 577738032Speter security implications. Patch from Alex Garthwaite of the 577838032Speter University of Pennsylvania. 577938032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 578038032Speter would truncate the address after "Full". Although the -f 578138032Speter syntax is incorrect (since it is in the envelope, it 578238032Speter shouldn't have comments and full names), the failure mode 578338032Speter was unnecessarily awful. 578438032Speter Fix a possible null pointer dereference when converting 8-bit data 578538032Speter to a 7-bit format. Problem noted by Jim Hutchins of 578638032Speter Sandia National Labs and David James of British Telecom. 578738032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 578838032Speter runs. Although this really shouldn't be used (F=9 is for 578938032Speter final delivery only, and using it on an SMTP mailer makes 579038032Speter it possible for a message to be converted from 8->7->8->7 579138032Speter bits several times), it shouldn't have failed with a syserr. 579238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 579338032Speter _Really_ fix the multiple :maildrop code in the user database 579438032Speter module. Patch from Roy Mongiovi of Georgia Tech. 579538032Speter Let F lines in the configuration file actually read root-only 579638032Speter files if the configuration file is safe. Based on a 579738032Speter patch from Keith Reynolds of SCO. 579838032Speter ETRN followed by QUIT would hold the connection open until the queue 579938032Speter run completed. Problem noted by Truck Lewis of TDK 580038032Speter Semiconductor Corp. 580138032Speter It turns out that despite the documentation, the TCP wrappers library 580238032Speter does _not_ log rejected connections. Do the logging ourselves. 580338032Speter Problem noted by Fletcher Mattox of the University of Texas 580438032Speter at Austin. 580538032Speter If sendmail finds a qf file in its queue directory that is an unknown 580638032Speter version (e.g., when backing out to an old version), the 580738032Speter error is reported on every queue run. Change it to only 580838032Speter give the error once (and rename the qf => Qf). Patch from 580938032Speter William A. Gianopoulos of Raytheon Company. 581038032Speter Start a new session when doing background delivery; currently it 581138032Speter ignored signals but didn't start a new signal, that caused 581238032Speter some problems if a background process tried to send mail 581338032Speter under certain circumstances. Problem noted by Eric Hagberg 581438032Speter of Morgan Stanley; fix from Kari Hurtta. 581538032Speter Simplify test for skipping a queue run to just check if the current 581638032Speter load average is >= the queueing load average. Previously 581738032Speter the check factored in some other parameters that caused it 581838032Speter to essentially never skip the queue run. Patch from Bryan 581938032Speter Costales. 582038032Speter If the SMTP server is running in "nullserver" mode (that is, it is 582138032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 582238032Speter (25) commands; this helps prevent a bad guy from putting 582338032Speter you into a tight loop as a denial-of-service attack. Based 582438032Speter on an e-mail conversation with Brad Knowles of AOL. 582538032Speter Slow down when too many "light weight" commands have been issued; 582638032Speter this helps prevent a class of denial-of-service attacks. 582738032Speter The current values and defaults are: 582838032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 582938032Speter MAXHELOCOMMANDS 3 HELO, EHLO 583038032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 583138032Speter MAXETRNCOMMANDS 8 ETRN 583238032Speter These will probably be configurable in a future release. 583338032Speter On systems that have uid_t typedefed to be an unsigned short, programs 583438032Speter that had the F=S flag and no U= equate would be invoked with 583538032Speter the real uid set to 65535 rather than being left unchanged. 583638032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 583738032Speter by Steve Hubert of the University of Washington, Seattle. 583838032Speter Mail that was Quoted-Printable encoded and had a soft line break on 583938032Speter the last line (i.e., an incomplete continuation) had the last 584038032Speter line dropped. Since this appears to be illegal it isn't 584138032Speter clear what to do with it, but flushing the last line seems 584238032Speter to be a better "fail soft" approach. Based on a patch from 584338032Speter Eric Hagberg. 584438032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 584538032Speter bogus HELO command still causes the "Polite people say HELO 584638032Speter first" error message. Problem pointed out by Chris Thomas 584738032Speter of UCLA; patch from John Beck of SunSoft. 584838032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 584971345Sgshapiro in PrivacyOptions.

Problem noted by Ronan KERYELL 588938032Speter of Centre de Recherche en Informatique de l'�cole Nationale 589038032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 589138032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 589238032Speter such as LUSER_RELAY. This change permits the following 589338032Speter syntaxes: ``local:'' will send to the same user on the 589438032Speter local machine (e.g., in a mailertable entry for "host", 589538032Speter ``local:'' will cause an address addressed to user@host to 589638032Speter go to user on the local machone). ``local:user'' will send 589738032Speter to the named user on the local machine. ``local:user@host'' 589838032Speter is equivalent to ``local:user'' (the host is ignored). In 589938032Speter all cases, the original user@host is passed in $@ (i.e., the 590038032Speter detail information). Inspired by a report from Michael Fuhr. 590138032Speter CONFIG: Strip quotes from the first word of an "error:" host 590238032Speter indication. This lets you set (for example) the LUSER_RELAY 590338032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 590438032Speter of the \" so that the resulting string is properly quoted. 590538032Speter Problem noted by Gregory Neil Shapiro of WPI. 590638032Speter OP.ME: documentation was inconsistent about whether sendmail did a 590738032Speter NOOP or a RSET to probe the connection (it does a RSET). 590838032Speter Inconsistency noted by Deeran Peethamparam. 590938032Speter OP.ME: insert additional blank pages so it will print properly on 591038032Speter a duplex printer. From Matthew Black of Cal State University, 591138032Speter Long Beach. 591238032Speter 591364562Sgshapiro8.8.4/8.8.4 1996/12/02 591438032Speter SECURITY: under some circumstances, an attacker could get additional 591538032Speter permissions by hard linking to files that were group 591638032Speter writable by the attacker. The solution is to disallow any 591738032Speter files that have hard links -- this will affect .forward, 591838032Speter :include:, and output files. Problem noted by Terry 591938032Speter Kyriacopoulos of Interlog Internet Services. As a 592038032Speter workaround, set UnsafeGroupWrites -- always a good idea. 592138032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 592238032Speter is, it is possible to do a denial-of-service attack on 592338032Speter MX hosts that rely on the use of the null MX list. There 592438032Speter is no danger if you have this option turned off (the default). 592538032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 592638032Speter unsafe. I know of no specific attack against this, although 592738032Speter a denial-of-service attack is probably possible, but in theory 592838032Speter you should not be able to safely tweak anything that affects 592938032Speter the permissions that are used when mail is delivered. 593038032Speter Purgestat could go into an infinite loop if one of the host status 593138032Speter directories somehow became empty. Problem noted by Roy 593238032Speter Mongiovi of Georgia Tech. 593338032Speter Processes got "lost" when counting children due to a race condition. 593438032Speter This caused "proc_list_probe: lost pid" messages to be logged. 593538032Speter Problem noted by several people. 593638032Speter On systems with System V SIGCLD child signal semantics (notably AIX 593738032Speter and HP-UX), mail transactions would print the message "451 593838032Speter SMTP-MAIL: lost child: No child processes". Problem noted 593938032Speter by several people. 594038032Speter Miscellaneous compiler warnings on picky compilers (or when setting 594138032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 594238032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 594338032Speter not be persistent between runs, since they are based on the 594438032Speter message rather than the host. Problem noted by Matt Dillon 594538032Speter of Best Internet Communications. 594638032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 594738032Speter of NCR (a.k.a., AT&T Global Information Solutions). 594838032Speter Avoid the possibility of having a child daemon run to completion 594938032Speter (including closing the SMTP socket) before the parent has 595038032Speter had a chance to close the socket; this can cause the parent 595138032Speter to hang for a long time waiting for the socket to drain. 595238032Speter Patch from Don Lewis of TDK Semiconductor. 595338032Speter If the fork() failed in a queue run, the queue runners would not be 595438032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 595538032Speter Some error conditions in ETRN could cause output without an SMTP 595638032Speter status code. Problem noted by Don Lewis. 595738032Speter Multiple :maildrop addresses in the user database didn't work properly. 595838032Speter Patch from Roy Mongiovi of Georgia Tech. 595938032Speter Add ".db" automatically onto any user database spec that does not 596038032Speter already have it; this is for consistency with makemap, the 596138032Speter K line, and the documentation. Inconsistency pointed out 596238032Speter by Roy Mongiovi. 596338032Speter Allow sendmail to be properly called in nohup mode. Patch from 596438032Speter Kyle Jones of UUNET. 596538032Speter Change ETRN to ignore but still update host status files; previously 596638032Speter it would ignore them and not save the updated status, which 596738032Speter caused stale information to be maintained. Based on a patch 596838032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 596938032Speter ETRN ignore the MinQueueAge option. 597038032Speter Patch long term host status to recover more gracefully from an empty 597138032Speter host status file condition. Patch from NAKAMURA Motonori 597238032Speter of Kyoto University. 597338032Speter Several patches to signal handling code to fix potential race 597438032Speter conditions from Don Lewis. 597538032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 597638032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 597738032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 597838032Speter compile flag; use NETINET instead. Solution based on a 597938032Speter patch from Bryan Costales. 598038032Speter PORTABILITY FIXES: 598138032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 598238032Speter /etc/security/passwd file when called as root. This 598338032Speter is very slow on some systems. To speed it up, use the 598438032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 598538032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 598638032Speter SCO 5.x: include -lprot in the Makefile.

Problem 602538032Speter noted by Eric Bishop of Virginia Tech. 602638032Speter When doing text-based host canonification (typically /etc/hosts 602738032Speter lookup), a null host name would match any /etc/hosts entry 602838032Speter with space at the end of the line. Problem noted by Steve 602938032Speter Hubert of the University of Washington, Seattle. 603038032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 603138032Speter Problem reported by Tom Smith of Digital Equipment Corp. 603238032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 603338032Speter size PACKETSZ (512) is not sufficient for some nameserver 603438032Speter answers containing very many resource records. The resolver 603538032Speter may also switch to TCP and retry if it detects UDP packet 603638032Speter overflow. Also, allow for the fact that the resolver 603738032Speter routines res_query and res_search return the size of the 603838032Speter *un*truncated answer in case the supplied answer buffer it 603938032Speter not big enough to accommodate the entire answer. Patch from 604038032Speter Eric Wassenaar. 604138032Speter Improvements to MaxDaemonChildren code. If you think you have too 604238032Speter many children, probe the ones you have to verify that they 604338032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 604438032Speter Also, do this probe before growing the vector of children 604538032Speter pids; this previously caused the vector to grow indefinitely 604638032Speter due to a race condition. Problem reported by Kyle Jones of 604738032Speter UUNET. 604838032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 604938032Speter O_EXLOCK to zero; this fools the map compilation code into 605038032Speter thinking that it can avoid race conditions by locking on open. 605138032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 605238032Speter Leif Erlingsson of Data Lege. 605338032Speter Always call res_init() on startup (if compiled in, of course) to 605438032Speter allow the sendmail.cf file to tweak resolver flags; without 605538032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 605638032Speter Andrew Sun of Merrill Lynch. 605738032Speter Improvements to host status printing code. Suggested by Steve Hubert 605838032Speter of the University of Washington, Seattle. 605938032Speter Change MinQueueAge option processing to do the check for the job age 606038032Speter when reading the queue file, rather than at the end; this 606138032Speter avoids parsing the addresses, which can do DNS lookups. 606238032Speter Problem noted by John Beck of InReference, Inc. 606338032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 606438032Speter properly escaped. Problem noted by Peter Nilsson of the 606538032Speter University of Linkoping. 606638032Speter In some cases, sendmail would retain root permissions during queue 606738032Speter runs even if RunAsUser was set. Problem noted by Mark 606838032Speter Thomas of Mark G. Thomas Consulting. 606938032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 607038032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 607138032Speter the envelope, and the receiving SMTP server speaks DSN, then 607238032Speter the DSN would be both generated locally and propagated to the 607338032Speter other end. 607438032Speter The U= mailer field didn't correctly extract the group id if the 607538032Speter user id was numeric.

If this option is null (as 614938032Speter opposed to undefined) it can cause "null signature" syserrs 615038032Speter on illegal host names. 615138032Speter If a Base64 encoded text/plain message has no trailing newline in 615238032Speter the encoded text, conversion back to 8 bits will drop the 615338032Speter final line. Problem noted by Pierre David. 615438032Speter If running with a RunAsUser, sendmail would give bogus "cannot 615538032Speter setuid" (or seteuid, or setreuid) messages on some systems. 615638032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 615738032Speter Always print error messages in -bv mode -- previously, -bv would 615838032Speter be absolutely silent on errors if the error mode was sent 615938032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 616038032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 616138032Speter term host status. This is necessary because it is common 616238032Speter to do this when you know a host has just come back up. 616338032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 616438032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 616538032Speter University of Leicester. 616638032Speter If a service (such as NIS) is specified as the last entry in the 616738032Speter service switch, but that service is not compiled in, sendmail 616838032Speter would return a temporary failure when an entry was not found 616938032Speter in the map. This caused the message to be queued instead of 617038032Speter bouncing immediately.

In order to avoid 621438032Speter trashing memory, the buffer for all names has only been 621538032Speter slightly increased in size, to 12.8K from 10.2K -- this means 621638032Speter that if a single name had 100 MX records, the average size 621738032Speter of those records could not exceed 128 bytes.

Berkeley. 622138032Speter Print q_statdate and q_specificity in address structure debugging 622238032Speter printout. 622338032Speter Expand MCI structure flag bits for debugging output. 622438032Speter Support IPv6-style domain literals, which can have colons between 622538032Speter square braces. 622638032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 622738032Speter this is an attempt to track down a bug that one person seems 622838032Speter to be having (it may be a Solaris bug!). 622938032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 623038032Speter this caused the NOTIFY info to sometimes be lost. Problem 623138032Speter pointed out by Claus Assmann of the 623238032Speter Christian-Albrechts-University of Kiel. 623338032Speter The statistics gathered in the sendmail.st file were too high; in 623438032Speter some cases failures (e.g., user unknown or temporary failure) 623538032Speter would count as a delivery as far as the statistics were 623638032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 623738032Speter Systems that don't have flock() would not send split envelopes in 623838032Speter the initial run. Problem pointed out by Leonard Zubkoff of 623938032Speter Dandelion Digital. 624038032Speter Move buffer overflow checking -- these primarily involve distrusting 624138032Speter results that may come from NIS and DNS. 624238032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 624338032Speter include <paths.h> and hence had the wrong pathnames for a few 624438032Speter things like /var/tmp. Reported by Matthew Green. 624538032Speter Conditions were reversed for the Priority: header, resulting in all 624638032Speter values being interpreted as non-urgent except for non-urgent, 624738032Speter which was interpreted as normal. Patch from Bryan Costales. 624838032Speter The -o (optional) flag was being ignored on hash and btree maps 624938032Speter since 8.7.2. Fix from Bryan Costales. 625038032Speter Content-Types listed in class "q" will always be encoded as 625138032Speter Quoted-Printable (or more accurately, will never be encoded 625238032Speter as base64). The class can have primary types (e.g., "text") 625338032Speter or full types (e.g., "text/plain"). Based on a suggestion by 625438032Speter Marius Olafsson of the University of Iceland. 625538032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 625638032Speter dialogue) so it can be passed to programs in mailers. 625738032Speter Define ${bodytype} to be the body type (from the -B flag or the 625838032Speter BODY= ESMTP parameter) so it can be passed to programs in 625938032Speter mailers. 626038032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 626138032Speter flag is set in the mailer descriptor. Suggested by John 626238032Speter Myers of CMU. 626338032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 626438032Speter The command takes a host name; data for that host is 626538032Speter immediately (and asynchronously) flushed. Because this shares 626638032Speter the -qR implementation, other hosts may be attempted, but 626738032Speter there should be no security implications. Implementation 626838032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 626938032Speter Add three new command line flags to pass in DSN parameters: -V envid 627038032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 627138032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 627238032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 627338032Speter that the -N flag applies to all recipients; there is no way 627438032Speter to specify per-address notifications on the command line, 627538032Speter nor is there an equivalent for the ORCPT= per-address 627638032Speter parameter. 627738032Speter Restore LogLevel option to be safe (it can only be increased); 627838032Speter apparently I went into paranoid mode between 8.6 and 8.7 627938032Speter and made it unsafe. Pointed out by Dabe Murphy of the 628038032Speter University of Maryland. 628138032Speter New logging on log level 15: all SMTP traffic. Patches from 628238032Speter Andrew Gross of San Diego Supercomputer Center. 628338032Speter NetInfo property value searching code wasn't stopping when it found 628438032Speter a match. This was causing the wrong values to be found (and 628538032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 628638032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 628738032Speter out by Bill Wisner of Electronics for Imaging that you can't 628838032Speter use the bracket address form for the MAIL_HUB macro, since 628938032Speter that causes the brackets to remain in the envelope recipient 629038032Speter address used for delivery. The simple fix (stripping off the 629138032Speter brackets in the config file) breaks the use of IP literal 629238032Speter addresses. This flag will solve that problem. 629338032Speter Add MustQuoteChars option. This is a list of characters that must 629438032Speter be quoted if they are found in the phrase part of an address 629538032Speter (that is, the full name part). The characters @,;:\()[] are 629638032Speter always in this list and cannot be removed. The default is 629738032Speter this list plus . and ' to match RFC 822. 629838032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 629938032Speter that do not include a host name for back compatibility with 630038032Speter some stupid SMTP clients. Setting this violates RFC 1123 630138032Speter section 5.2.5. 630238032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 630338032Speter rejecting connections if it has more than this many 630438032Speter outstanding children accepting mail. Note that you may 630538032Speter see more processes than this because of outgoing mail; this 630638032Speter is for incoming connections only. 630738032Speter Add ConnectionRateThrottle option. If set to a positive value, the 630838032Speter number of incoming SMTP connections that will be permitted 630938032Speter in a single second is limited to this number. Connections are 631038032Speter not refused during this time, just deferred. The intent is to 631138032Speter flatten out demand so that load average limiting can kick in. 631238032Speter It is less radical than MaxDaemonChildren, which will stop 631338032Speter accepting connections even if all the connections are idle 631438032Speter (e.g., due to connection caching). 631538032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 631638032Speter specifies how long cached information about the state of a 631738032Speter host will be kept before they are considered stale and the 631838032Speter host is retried. If you are using persistent host status 631938032Speter (i.e., the HostStatusDirectory option is set) this will apply 632038032Speter between runs; otherwise, it applies only within a single queue 632138032Speter run and hence is useful only for hosts that have large queues 632238032Speter that take a very long time to run. 632338032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 632438032Speter into being a single line even if they had newlines in them 632538032Speter when read. This is to get around a botch in Lotus Notes. 632638032Speter Text class maps were totally broken -- if you ever retrieved the last 632738032Speter item in a table it would be truncated. Problem noted by 632838032Speter Gregory Neil Shapiro of WPI. 632938032Speter Extend the lines printed by the mailq command (== the -bp flag) when 633038032Speter -v is given to 120 characters; this allows more information 633138032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 633238032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 633338032Speter this was treated as end-of-input. Problem noted by Bryan 633438032Speter Costales. 633538032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 633638032Speter to the queue file. Fix from John Hughes of Atlantic 633738032Speter Technologies, Inc. 633838032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 633938032Speter if this happens in a queue run it can cause nasty delays. 634038032Speter Problem noted by Mark Horton of AT&T. 634138032Speter If userdb entries pointed to userdb entries, and there were multiple 634238032Speter values for a given key, the database cursor would get 634338032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 634438032Speter of Georgia Tech. Fixed by reading all the values and creating 634538032Speter a comma-separated list; thus, the -v output will be somewhat 634638032Speter different for this case. 634738032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 634838032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 634938032Speter of Stanford University. 635038032Speter When envelopes were split due to aliases with owner- aliases, and 635138032Speter there was some error on one of the lists, more than one of 635238032Speter the owners would get the message. Problem pointed out by 635338032Speter Roy Mongiovi of Georgia Tech. 635438032Speter Detect excessive recursion in macro expansions, e.g., $X defined 635538032Speter in terms of $Y which is defined in terms of $X. Problem 635638032Speter noted by Bryan Costales; patch from Eric Wassenaar. 635738032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 635838032Speter some cases get trashed causing bogus From_ lines. Fix from 635938032Speter Kyle Jones of UUNET. 636038032Speter When doing load average initialization, if the nlist call for avenrun 636138032Speter failed, the second and subsequent lookups wouldn't notice 636238032Speter that fact causing bogus load averages to be returned. Noted 636338032Speter by Casper Dik of Sun Holland. 636438032Speter Fix problem with incompatibility with some versions of inet_aton that 636538032Speter have changed the return value to unsigned, so a check for an 636638032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 636738032Speter This could cause mail to addresses such as [foo.com] to bounce 636838032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 636938032Speter Pasteur Institute. 637038032Speter DSNs were inconsistent if a failure occurred during the DATA phase 637138032Speter rather than the RCPT phase: the Action: would be correct, but 637238032Speter the detailed status information would be wrong. Problem noted 637338032Speter by Bob Snyder of General Electric Company. 637438032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 637538032Speter that this is the initial MUA->MTA submission. The flag current 637638032Speter does nothing, but in future releases (when MUAs start using 637738032Speter these flags) it will probably turn on things like DNS 637838032Speter canonification. 637938032Speter Default end-of-line string (E= specification on mailer [M] lines) 638038032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 638138032Speter mailers. 638238032Speter Change the internal definition for the *file* and *include* mailers 638338032Speter to have $u in the argument vectors so that they aren't 638438032Speter misinterpreted as SMTP mailers and thus use \r\n line 638538032Speter termination. This will affect anyone who has redefined 638638032Speter either of these in their configuration file. 638738032Speter Don't assume that IDENT servers close the connection after a query; 638838032Speter responses can be newline terminated. From Terry Kennedy of 638938032Speter St. Peter's College. 639038032Speter Avoid core dumps on erroneous configuration files that have 639138032Speter $#mailer with nothing following. From Bryan Costales. 639238032Speter Avoid null pointer dereference with high debug values in unlockqueue. 639338032Speter Fix from Randy Martin of Clemson University. 639438032Speter Fix possible buffer overrun when expanding very large macros. Fix 639538032Speter from Kyle Jones of UUNET. 639638032Speter After 25 EXPN or VRFY commands, start pausing for a second before 639738032Speter processing each one. This avoids a certain form of denial 639838032Speter of service attack. Potential attack pointed out by Bryan 639938032Speter Costales. 640038032Speter Allow new named (not numbered!) config file rules to do validity 640138032Speter checking on SMTP arguments: check_mail for MAIL commands and 640238032Speter check_rcpt for RCPT commands. These rulesets can do anything 640338032Speter they want; their result is ignored unless they resolve to the 640438032Speter $#error mailer, in which case the indicated message is printed 640538032Speter and the command is rejected. Similarly, the check_compat 640638032Speter ruleset is called before delivery with "from_addr $| to_addr" 640738032Speter (the $| is a meta-symbol used to separate the two addresses); 640838032Speter it can give a "this sender can't send to this recipient" 640938032Speter notification. Note that this patch allows $| to stand alone 641038032Speter in rulesets. 641138032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 641238032Speter that have the name, IP address, and port number (respectively) 641338032Speter of the SMTP client (that is, the entity at the other end of 641438032Speter the connection. These can be used in (e.g.) check_rcpt to 641538032Speter verify that someone isn't trying to relay mail through your 641638032Speter host inappropriately. Be sure to use the deferred evaluation 641738032Speter form, for example $&{client_name}, to avoid having these bound 641838032Speter when sendmail reads the configuration file. 641938032Speter Add new config file rule check_relay to check the incoming connection 642038032Speter information. Like check_compat, it is passed the host name 642138032Speter and host address separated by $| and can reject connections 642238032Speter on that basis. 642338032Speter Allow IDA-style recursive function calls. Code contributed by Mark 642438032Speter Lovell and Paul Vixie. 642538032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 642638032Speter a virtual UUCP address using either a domain address or the $k 642738032Speter macro. Based on code contributed by Mark Lovell and Paul 642838032Speter Vixie. 642938032Speter Add Stanford LDAP map. Requires special libraries that are not 643038032Speter included with sendmail. Contributed by Booker C. Bense 643138032Speter <bbense@networking.stanford.edu>; contact him for support. 643238032Speter See also the src/READ_ME file. 643338032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 643438032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 643538032Speter only for debugging deep bits of code where it is important to 643638032Speter distinguish between the single-character metasymbol $+ and the 643738032Speter two characters $, +. 643838032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 643938032Speter debug_dumpstate. 644038032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 644138032Speter files that are group writable are considered "unsafe" -- that 644238032Speter is, programs and files referenced from such files are not 644338032Speter valid recipients. 644438032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 644538032Speter name that was not in DNS or was a domain-literal. Problem 644638032Speter noted by Tom May. 644738032Speter Change the introduction to error messages to more clearly delineate 644838032Speter permanent from temporary failures; if both existed in a 644938032Speter single message it could be confusing. Suggested by John 645038032Speter Beck of InReference, Inc. 645138032Speter The IngoreDot (i) option didn't work for lines that were terminated 645238032Speter with CRLF. Problem noted by Ted Stockwell of Secure 645338032Speter Computing Corporation. 645438032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 645538032Speter message headers. Problem reported by Matt Dillon of Best 645638032Speter Internet Communications. 645738032Speter Check for bogus characters in the 0200-0237 range; since these are 645838032Speter used internally, very strange errors can occur if those 645938032Speter characters appear in headers. Problem noted by Anders Gertz 646038032Speter of Lysator. 646138032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 646238032Speter recipient mailer has the F=9 flag set, and only works on 646338032Speter text/plain body types. Code contributed by Marius Olafsson 646438032Speter of the University of Iceland. 646538032Speter Special case "postmaster" name so that it is always treated as lower 646638032Speter case in alias files regardless of configuration settings; 646738032Speter this prevents some potential problems where "Postmaster" or 646838032Speter "POSTMASTER" might not match "postmaster". In most cases 646938032Speter this change is a no-op. 647038032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 647138032Speter Costales. 647238032Speter The -a map flag was ignored for dequote maps. Problem noted by 647338032Speter Bryan Costales. 647438032Speter Fix core dump when a lookup of a class "prog" map returns no 647538032Speter response. Patch from Bryan Costales. 647638032Speter Log instances where sendmail is deferring or rejecting connections 647738032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 647838032Speter Include port number in process title for network daemons. Suggested 647938032Speter by Kyle Jones of UUNET. 648038032Speter Send ``double bounces'' (errors that occur when sending an error 648138032Speter message) to the address indicated in the DoubleBounceAddress 648238032Speter option (default: postmaster). Previously they were always 648338032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 648438032Speter Add new mode, -bD, that acts like -bd in all respects except that 648538032Speter it runs in foreground. This is useful for using with a 648638032Speter wrapper that "watches" system services. Suggested by Kyle 648738032Speter Jones of UUNET. 648838032Speter Fix botch in spacing around (parenthesized) comments in addresses 648938032Speter when the comment comes before the address. Patch from 649038032Speter Motonori Nakamura of Kyoto University. 649138032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 649238032Speter that are being bounced to postmaster, rather than "Returned 649338032Speter mail". This permits the person who is postmaster more 649438032Speter easily determine what messages are to their role as 649538032Speter postmaster versus bounces to mail they actually sent. Based 649638032Speter on a suggestion by Motonori Nakamura. 649738032Speter Add new value "time" for QueueSortOrder option; this causes the queue 649838032Speter to be sorted strictly by the time of submission. Note that 649943730Speter this can cause very bad behavior over slow lines (because 650038032Speter large jobs will tend to delay small jobs) and on nodes with 650138032Speter heavy traffic (because old things in the queue for hosts that 650238032Speter are down delay processing of new jobs). Also, this does not 650338032Speter guarantee that jobs will be delivered in submission order 650438032Speter unless you also set DeliveryMode=queue. In general, it should 650538032Speter probably only be used on the command line, and only in 650638032Speter conjunction with -qRhost.domain. In fact, there are very few 650738032Speter cases where it should be used at all. Based on an 650838032Speter implementation by Motonori Nakamura. 650938032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 651038032Speter the same manner as other rulesets. Previously a temporary 651138032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 651238032Speter of Stanford University. 651338032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 651438032Speter 5yz (permanent failure) code. The next MX host will still be 651538032Speter tried if the connection cannot be opened in the first place 651638032Speter or if the MAIL command returns a 4yz (temporary failure) code. 651738032Speter (It's hard to know what to do here, since neither RFC 974 nor 651838032Speter RFC 1123 specify when to proceed to the next MX host.) 651938032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 652038032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 652138032Speter This causes map lookups that get a temporary failure (e.g., 652238032Speter name server failure) to _not_ defer the delivery of the 652338032Speter message. This should only be used if your configuration file 652438032Speter is prepared to do something sensible in this case. Based on 652538032Speter an idea by Gregory Shapiro of WPI. 652638032Speter Fix problem finding network interface addresses. Patch from 652738032Speter Motonori Nakamura. 652838032Speter Don't reject qf entries that are not owned by your effective uid if 652990792Sgshapiro you are not running set-user-ID; this makes management of 653080785Sgshapiro certain kinds of firewall setups difficult. Patch 653180785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 653238032Speter Add persistent host status. This keeps the information normally 653338032Speter maintained within a single queue run in disk files that are 653438032Speter shared between sendmail instances. The HostStatusDirectory 653538032Speter is the directory in which the information is maintained. If 653638032Speter not set, persistent host status is turned off. If not a full 653738032Speter pathname, it is relative to the queue directory. A common 653838032Speter value is ".hoststat". 653938032Speter There are also two new operation modes: 654038032Speter * -bh prints the status of hosts that have had recent 654138032Speter connections. 654238032Speter * -bH purges the host statuses. No attempt is made to save 654338032Speter recent status information. 654438032Speter This feature was originally written by Paul Vixie of Vixie 654538032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 654638032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 654738032Speter with my insistence that things fit cleanly into the V8 654838032Speter framework is gratefully appreciated. 654938032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 655038032Speter operate). Avoids letting two sendmails on the local machine 655164562Sgshapiro open connections to the same remote host at the same time. 655238032Speter This reduces load on the other machine, but can cause mail to 655338032Speter be delayed (for example, if one sendmail is delivering a huge 655438032Speter message, other sendmails won't be able to send even small 655538032Speter messages). Also, it requires another file descriptor (for the 655638032Speter lock file) per connection, so you may have to reduce 655738032Speter ConnectionCacheSize to avoid running out of per-process 655838032Speter file descriptors. Based on the persistent host status code 655938032Speter contributed by Paul Vixie and Mark Lovell. 656038032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 656138032Speter SafeFileEnvironment option is set. Problem noted by Bryan 656238032Speter Costales. 656338032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 656438032Speter file. Problem noted by Bryan Costales. 656538032Speter If a job was aborted using the interrupt signal (e.g., control-C from 656638032Speter the keyboard), on some occasions an empty df file would be 656738032Speter left around; these would collect in the queue directory. 656838032Speter Problem noted by Bryan Costales. 656938032Speter Change the makesendmail script to enhance the search for Makefiles 657038032Speter based on release number. For example, on SunOS 5.5.1, it will 657138032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 657238032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 657338032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 657438032Speter Webmasters. 657538032Speter When creating maps using "newaliases", always map the keys to lower 657638032Speter case when creating the map unless the -f flag is specified on 657738032Speter the map itself. Previously this was done based on the F=u 657838032Speter flag in the local mailer, which meant you could create aliases 657938032Speter that you could never access. Problem noted by Bob Wu of DEC. 658038032Speter When a job was read from the queue, the bits causing notification on 658138032Speter failure or delay were always set. This caused those 658238032Speter notifications to be sent even if NOTIFY=NEVER had been 658338032Speter specified. Problem noted by Steve Hubert of the University 658438032Speter of Washington, Seattle. 658538032Speter Add new configurable routine validate_connection (in conf.c). This 658638032Speter lets you decide if you are willing to accept traffic from 658738032Speter this host. If it returns FALSE, all SMTP commands will return 658838032Speter "550 Access denied". -DTCPWRAPPERS will include support for 658938032Speter TCP wrappers; you will need to add -lwrap to the link line. 659038032Speter (See src/READ_ME for details.) 659138032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 659238032Speter bounces. Some people seemed to think that this could be 659338032Speter confusing (even though it is true). Suggested by Motonori 659438032Speter Nakamura. 659538032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 659638032Speter user early in processing to avoid potential security problems. 659738032Speter However, this means that all .forward and :include: files must 659838032Speter be readable by that user, and all files to be written must be 659938032Speter writable by that user and all programs will be executed by that 660038032Speter user. It is also incompatible with the SafeFileEnvironment 660138032Speter option. In other words, it may not actually add much to 660238032Speter security. However, it should be useful on firewalls and other 660338032Speter places where users don't have accounts and the aliases file is 660438032Speter well constrained. 660538032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 660638032Speter only on the first attempt to delivery to an address. It could 660738032Speter be set to be lower than Timeout.connect on the principle that 660838032Speter the mail should go through quickly to responsive hosts; less 660938032Speter responsive hosts get to wait for the next queue run. 661038032Speter Fix a problem on Solaris that occasionally causes programs 661138032Speter (such as vacation) to hang with their standard input connected 661238032Speter to a UDP port. It also created some signal handling problems. 661338032Speter The problems turned out to be an interaction between vfork(2) 661438032Speter and some of the libraries, particularly NIS/NIS+. I am 661538032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 661638032Speter Change user class map to do the same matching that actual delivery 661738032Speter will do instead of just a /etc/passwd lookup. This adds 661838032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 661938032Speter The Timeout.* options are not safe -- they can be used to create a 662038032Speter denial-of-service attack. Problem noted by Christophe 662138032Speter Wolfhugel. 662243730Speter Don't send PostmasterCopy messages in the event of a "delayed" 662338032Speter notification. Suggested by Barry Bouwsma. 662438032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 662538032Speter option is set, since this disables VERB mode. Suggested 662638032Speter by John Hawkinson of MIT. 662738032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 662838032Speter by Motonori Nakamura of Kyoto University. 662938032Speter Only queue messages on transient .forward open failures if there 663043730Speter were no successful opens. The previous behavior caused it 663138032Speter to queue even if a "fall back" .forward was found. Problem 663238032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 663338032Speter and Computer Science (DISCS), NUS, Singapore. 663438032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 663538032Speter is bouncing because of a MIME error during 8->7 bit conversion; 663638032Speter the encapsulated message will bounce again, causing a loop. 663738032Speter Problem noted by Steve Hubert of the University of Washington. 663838032Speter Create xf (transcript) files using the TempFileMode option value 663938032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 664038032Speter National University of Singapore. 664138032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 664238032Speter detect cases where DefaultUid is set to something that the 664338032Speter system can't cope with. 664438032Speter PORTABILITY FIXES: 664538032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 664638032Speter Atlas International. 664738032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 664838032Speter <bicknell@ufp.org>. 664938032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 665038032Speter work on the first recipient of a message due to a 665138032Speter bug in the getpwent family.

Based on a patch from Randall 669438032Speter Winchester of the University of Maryland. 669538032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 669638032Speter Robert La Ferla of Hot Software. 669738032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 669838032Speter (where "code" is an exit status) on domains (previously 669938032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 670038032Speter Foundation. 670138032Speter CONFIG: hooks for IPv6-style domain literals. 670238032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 670338032Speter if it is undefined the AliasFile option is never set; this 670438032Speter should be transparent for most everyone. Suggested by John 670538032Speter Myers of CMU. 670638032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 670738032Speter domain listed in $=w is masqueraded. With it, only those 670838032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 670938032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 671038032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 671138032Speter hosts under those domains as well as the domain headers 671238032Speter themselves. For example, if a configuration had 671338032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 671438032Speter foo.com would be masqueraded; with it, *.foo.com would be 671538032Speter masqueraded as well. Based on an implementation by Richard 671638032Speter (Pug) Bainter of U. Texas. 671738032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 671838032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 671938032Speter Keys are user names; values are outgoing mail addresses. Yes, 672038032Speter this does overlap with the user database, and figuring out 672138032Speter just when to use which one may be tricky. Based on code 672238032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 672338032Speter from Per Hedeland of Ericsson. 672438032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 672538032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 672638032Speter Keys are either fully qualified addresses or just the host 672738032Speter part (with the @ sign). For example, a table containing: 672838032Speter info@foo.com foo-info 672938032Speter info@bar.com bar-info 673038032Speter @baz.org jane@elsewhere.net 673138032Speter would send all mail destined for info@foo.com to foo-info 673238032Speter (which is presumably an alias), mail addressed to info@bar.com 673338032Speter to bar-info, and anything addressed to anyone at baz.org will 673438032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 673538032Speter and baz.org must all be in $=w. Based on discussions with 673638032Speter a great many people. 673738032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 673838032Speter Suggested by Richard Bainter. 673938032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 674038032Speter "fax" mailer. 674138032Speter CONFIG: allow mailertable entries to resolve to local:user; this 674238032Speter passes the original user@host in to procmail-style local 674338032Speter mailers as the "detail" information to allow them to do 674438032Speter additional clever processing. From Joe Pruett of 674538032Speter Teleport Corporation. Delivery to the original user can 674638032Speter be done by specifying "local:" (with nothing after the colon). 674738032Speter CONFIG: allow any context that takes "mailer:domain" to also take 674838032Speter "mailer:user@domain" to force mailing to the given user; 674938032Speter "local:user" can also be used to do local delivery. This 675038032Speter applies on *_RELAY and in the mailertable entries. Based 675138032Speter on a suggestion by Ribert Kiessling of Easynet. 675238032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 675338032Speter limits the possible domains; this reduces the number of DNS 675438032Speter lookups required to support this feature. For example, 675538032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 675638032Speter to domains under my.site.com. Code contributed by Anthony 675738032Speter Thyssen <anthony@cit.gu.edu.au>. 675838032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 675938032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 676038032Speter of WPI. 676138032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 676238032Speter event you have to define local mailers. Suggested by 676338032Speter Gregory Shapiro of WPI. 676438032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 676538032Speter be misinterpreted as a list:...; syntax. Based on a patch by 676638032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 676738032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 676838032Speter remotely connected. The address host!user was being 676938032Speter converted to host!user@thishost instead of host!user@uurelay. 677038032Speter Problem noted by William Gianopoulos of Raytheon Company. 677138032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 677238032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 677338032Speter "User has moved"; the former wording was confusing if the 677438032Speter new address is still on the local host. Based on a suggestion 677538032Speter by Andreas Luik. 677638032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 677738032Speter However, the class is not pre-initialized to contain root. 677838032Speter Suggested by Gregory Neil Shapiro. 677938032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 678038032Speter Wolfhugel. 678138032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 678238032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 678338032Speter well: this produces a slightly different mailbox format (no 678438032Speter Content-Length: headers), file ownerships and modes are 678538032Speter different (not owned by group mail; mode 600 instead of 660), 678638032Speter and the local mailer flags will have to be tweaked (make them 678738032Speter match bsd4.4) in order to use this mailer. Patches from Paul 678838032Speter Hammann of the Missouri Research and Education Network. 678938032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 679038032Speter was a delivery error, such as if the ownership on the file 679138032Speter was wrong or the mode changed between the initial stat and 679238032Speter the open.

They were not 687838032Speter properly repaired in 8.7.1. 687938032Speter Completely delete the Bcc: header if and only if there are other 688038032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 688138032Speter last being a historic botch, of course). If Bcc: is the 688238032Speter only recipient header in the message, its value is tossed, 688343730Speter but the header name is kept. The old behavior (always keep 688438032Speter the header name and toss the value) allowed primary recipients 688538032Speter to see that a Bcc: went to _someone_. 688638032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 688738032Speter sender to <address> using -f'' syslog messages. Suggested 688838032Speter by Kari Hurtta. 688938032Speter If a sequence or switch map lookup entry gets a tempfail but then 689038032Speter continues on to another map type, but the name is not found, 689138032Speter return a temporary failure from the sequence or switch map. 689238032Speter For example, if hosts search ``dns files'' and DNS fails 689338032Speter with a tempfail, the hosts map will go on and search files, 689438032Speter but if it fails the whole thing should be a tempfail, not 689538032Speter a permanent (host unknown) failure, even though that is the 689638032Speter failure in the hosts.files map. This error caused hard 689738032Speter bounces when it should have requeued. 689838032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 689990792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 690038032Speter working properly due to excessive paranoia. Pointed out by 690138032Speter John Hawkinson of Panix. 690238032Speter An SMTP RCPT command referencing a host that gave a nameserver 690338032Speter timeout would return a 451 command (8.6 accepted it and 690443730Speter queued it locally). Revert to the 8.6 behavior in order 690538032Speter to simplify queue management for clustered systems. Suggested 690638032Speter by Gregory Neil Shapiro of WPI. The same problem could break 690738032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 690838032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 690938032Speter Infobiogen. 691038032Speter Fix possible buffer overflow in munchstring(). This was not a security 691138032Speter problem because you couldn't specify any argument to this 691238032Speter without first giving up root privileges, but it is still a 691338032Speter good idea to avoid future problems.

Pointed out by Allan Johannesen of WPI. 693238032Speter Config files that had no AliasFile definition were defaulting to 693338032Speter using /etc/aliases; this caused problems with nullclient 693438032Speter configurations.

Fix from Brian Coan of the 696638032Speter Association for Progressive Communications. 696738032Speter If MinQueueAge was set and a message was considered but not run 696838032Speter during a queue run and the Timeout.queuereturn interval was 696938032Speter reached, a "timed out" error message would be returned that 697038032Speter didn't include the failed address (and claimed to be a warning 697138032Speter even though it was fatal). The fix is to not return such 697238032Speter messages until they are actually tried, i.e., in the next 697338032Speter MinQueueAge interval.

From Tom Moore of AT&T GIS. 703038032Speter Shorten parameters passed to syslog() in some contexts to avoid a 703138032Speter bug in many vendors' implementations of that routine. Although 703238032Speter this isn't really a bug in sendmail per se, and my solution 703338032Speter has to assume that syslog() has at least a 1K buffer size 703438032Speter internally (I know some vendors have shortened this 703538032Speter dramatically -- they're on their own), sendmail is a popular 703638032Speter target. Also, limit the size of %s arguments in sprintf. 703738032Speter These both have possible security implications. Solutions 703838032Speter suggested by Casper Dik of Sun's Network Security Group 703938032Speter (Holland), Mark Seiden, and others. 704038032Speter Fix a problem that might cause a non-standard -B (body type) 704138032Speter parameter to be passed to the next server with undefined 704238032Speter results.

Robert 705038032Speter Elz. 705138032Speter Avoid some possible null pointer dereferences. Fixes from Randy 705238032Speter Martin <WOLF@CLEMSON.EDU> 705338032Speter When sendmail starts up on systems that have no fully qualified 705438032Speter domain name (FQDN) anywhere in the first matching host map 705538032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 705638032Speter sendmail would sleep to try to find a FQDN, which it really 705738032Speter really needs. This has been changed to fall through to the 705838032Speter next map type if it can't find a FQDN -- i.e., if the hosts 705938032Speter file doesn't have a FQDN, it will try dns even though the 706038032Speter short name was found in /etc/hosts. This is probably a crock, 706138032Speter but many people have hosts files without FQDNs. Remember: 706238032Speter domain names are your friends. 706338032Speter Log a high-priority message if you can't find your FQDN during startup. 706438032Speter Suggested by Simon Barnes of Schlumberger Limited. 706538032Speter When using Hesiod, initialize it early to improve error reporting. 706638032Speter Patch from Don Lewis of Silicon Systems, Inc. 706738032Speter Apparently at least some versions of Linux have a 90 !minute!

Problem noted by Thomas Dwyer III 719538032Speter of Michigan Technological University. 719638032Speter Relax chownsafe rules slightly -- old version said that if you 719738032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 719838032Speter if fpathconf returned EINVAL or ENOSYS), assume that 719938032Speter chown is not safe. The new version falls back to whether 720038032Speter you are on a BSD system or not. This is important for 720138032Speter SunOS, which apparently always returns one of those 720238032Speter error codes. This impacts whether you can mail to files 720338032Speter or not. 720438032Speter Syntax errors such as unbalanced parentheses in the configuration 720538032Speter file could be omitted if you had "Oem" prior to the 720638032Speter syntax error in the config file. Change to always print 720738032Speter the error message. It was especially weird because it 720838032Speter would cause a "warning" message to be sent to the Postmaster 720938032Speter for every message sent (but with no transcript). Problem 721038032Speter noted by Gregory Paris of Motorola. 721138032Speter Rewrite collect and putbody to handle full 8-bit data, including 721238032Speter zero bytes. These changes are internally extensive, but 721338032Speter should have minimal impact on external function. 721438032Speter Allow full words for option names -- if the option letter is 721538032Speter (apparently) a space, then take the word following -- e.g., 721638032Speter O MatchGECOS=TRUE 721738032Speter The full list of old and new names is as follows: 721838032Speter 7 SevenBitInput 721938032Speter 8 EightBitMode 722038032Speter A AliasFile 722138032Speter a AliasWait 722238032Speter B BlankSub 722338032Speter b MinFreeBlocks/MaxMessageSize 722438032Speter C CheckpointInterval 722538032Speter c HoldExpensive 722638032Speter D AutoRebuildAliases 722738032Speter d DeliveryMode 722838032Speter E ErrorHeader 722938032Speter e ErrorMode 723038032Speter f SaveFromLine 723138032Speter F TempFileMode 723238032Speter G MatchGECOS 723338032Speter H HelpFile 723438032Speter h MaxHopCount 723538032Speter i IgnoreDots 723638032Speter I ResolverOptions 723738032Speter J ForwardPath 723838032Speter j SendMimeErrors 723938032Speter k ConnectionCacheSize 724038032Speter K ConnectionCacheTimeout 724138032Speter L LogLevel 724238032Speter l UseErrorsTo 724338032Speter m MeToo 724438032Speter n CheckAliases 724538032Speter O DaemonPortOptions 724638032Speter o OldStyleHeaders 724738032Speter P PostmasterCopy 724838032Speter p PrivacyOptions 724938032Speter Q QueueDirectory 725038032Speter q QueueFactor 725138032Speter R DontPruneRoutes 725238032Speter r, T Timeout 725338032Speter S StatusFile 725438032Speter s SuperSafe 725538032Speter t TimeZoneSpec 725638032Speter u DefaultUser 725738032Speter U UserDatabaseSpec 725843730Speter V FallbackMXHost 725938032Speter v Verbose 726038032Speter w TryNullMXList 726138032Speter x QueueLA 726238032Speter X RefuseLA 726338032Speter Y ForkEachJob 726438032Speter y RecipientFactor 726538032Speter z ClassFactor 726638032Speter Z RetryFactor 726738032Speter The old macros that passed information into sendmail have 726838032Speter been changed to options; those correspondences are: 726938032Speter $e SmtpGreetingMessage 727038032Speter $l UnixFromLine 727138032Speter $o OperatorChars 727238032Speter $q (deleted -- not necessary) 727338032Speter To avoid possible problems with an older sendmail, 727438032Speter configuration level 6 is accepted by this version of 727538032Speter sendmail; any config file using the new names should 727638032Speter specify "V6" in the configuration. 727738032Speter Change address parsing to properly note that a phrase before a 727838032Speter colon and a trailing semicolon are essentially the same 727938032Speter as text outside of angle brackets (i.e., sendmail should 728038032Speter treat them as comments). This is to handle the 728138032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 728238032Speter assume that ``group name:'' is a comment on the first 728338032Speter address and the ``;'' is a comment on the last address). 728438032Speter This requires config file support to get right. It does 728538032Speter understand that :: is NOT this syntax, and can be turned 728638032Speter off completely by setting the ColonOkInAddresses option. 728738032Speter Level 6 config files added with new mailer flags: 728838032Speter A Addresses are aliasable. 728938032Speter i Do udb rewriting on envelope as well as header 729038032Speter sender lines. Applies to the from address mailer 729138032Speter flags rather than the recipient mailer flags. 729238032Speter j Do udb rewriting on header recipient addresses. 729338032Speter Applies to the sender mailer flags rather than the 729438032Speter recipient mailer flags. 729538032Speter k Disable check for loops when doing HELO command. 729638032Speter o Always run as the mail recipient, even on local 729738032Speter delivery. 729838032Speter w Check for an /etc/passwd entry for this user. 729938032Speter 5 Pass addresses through ruleset 5. 730038032Speter : Check for :include: on this address. 730138032Speter | Check for |program on this address. 730238032Speter / Check for /file on this address. 730338032Speter @ Look up sender header addresses in the user 730438032Speter database. Applies to the mailer flags for the 730538032Speter mailer corresponding to the envelope sender 730638032Speter address, rather than to recipient mailer flags. 730738032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 730838032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 730938032Speter mailers, and the ColonOkInAddresses option. 731038032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 731138032Speter John Beck of Hewlett-Packard, who generously contributed 731238032Speter their implementation to me, which I then didn't use (see 731338032Speter mime.c for an explanation of why). This adds the 731438032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 731538032Speter to control handling of 8-bit data. These have to cope with 731638032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 731738032Speter 8-bit data that is entered without declaring it as 8-bit 731838032Speter MIME -- technically this is illegal according to the 731938032Speter specs) and labelled 8-bit data (that is, it was declared 732038032Speter as 8BITMIME in the ESMTP session or by using the 732138032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 732238032Speter set then 8-bit data is sent to non-8BITMIME machines 732338032Speter instead of converting to 7 bit (essentially using 732438032Speter just-send-8 semantics). The values for EightBitMode are: 732538032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 732638032Speter any necessary conversion of 8BITMIME to 7BIT 732738032Speter (essentially, the full MIME option). 732838032Speter p pass unlabelled 8-bit input, but convert labelled 732938032Speter 8BITMIME input to 7BIT as required (default). 733038032Speter s strict adherence: reject unlabelled 8-bit input, 733138032Speter convert 8BITMIME to 7BIT as required. The F=8 733238032Speter flag is ignored. 733338032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 733438032Speter the setting of F=8. 733538032Speter Add new internal class 'n', which is the set of MIME Content-Types 733638032Speter which can not be 8 to 7 bit encoded because of other 733738032Speter considerations. Types "multipart/*" and "message/*" are 733838032Speter never directly encoded (although their components can be). 733938032Speter Add new internal class 's', which is the set of subtypes of the 734038032Speter MIME message/* content type that can be treated as though 734138032Speter they are an RFC822 message. It is predefined to have 734238032Speter "rfc822". Suggested By Kari Hurtta. 734338032Speter Add new internal class 'e'. This is the set of MIME 734438032Speter Content-Transfer-Encodings that can be converted to 734538032Speter a seven bit format (Quoted-Printable or Base64). It is 734638032Speter preinitialized to contain "7bit", "8bit", and "binary". 734738032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 734838032Speter short name) to set the default character set to use in the 734938032Speter Content-Type: header when doing encoding of an 8-bit message 735038032Speter which isn't marked as MIME into MIME format. If the C= 735138032Speter parameter is set on the Envelope From address, use that as 735238032Speter the default encoding; else use the DefaultCharSet option. 735338032Speter If neither is set, it defaults to "unknown-8bit" as 735438032Speter suggested by RFC 1428 section 3. 735538032Speter Allow ``U=user:group'' field in mailer definition to set a default 735638032Speter user and group that a mailer will be executed as. This 735738032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 735838032Speter also set, it is the uid/gid that will always be used (that 735938032Speter is, the controlling address is ignored). The values may be 736038032Speter numeric or symbolic; if only a symbolic user is given (no 736138032Speter group) that user's default group in the passwd file is used 736238032Speter as the group. Based on code donated by Chip Rosenthal of 736338032Speter Unicom. 736438032Speter Allow `u' option to also accept user:group as a value, in the same 736538032Speter fashion as the U= mailer option. 736638032Speter Add the symbolic time zone name in the Arpanet format dates (as 736738032Speter a comment). This adds a new compile-time configuration 736838032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 736938032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 737038032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 737138032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 737238032Speter timezone()), or TZ_NONE (don't include the comment). Code 737338032Speter from Chip Rosenthal. 737438032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 737538032Speter For example, 737638032Speter O Timeout.helo = 2m 737738032Speter There are also two new suboptions "queuereturn" and 737838032Speter "queuewarn"; these subsume the old T option. Thus, to 737938032Speter set them both the preferred new syntax is 738038032Speter O Timeout.queuereturn = 5d 738138032Speter O Timeout.queuewarn = 4h 738238032Speter Sort queue by host name instead of by message priority if the 738338032Speter QueueSortOrder option (no short name) is set is set to 738438032Speter ``host''. This makes better use of the connection cache, 738538032Speter but may delay more ``interactive'' messages behind large 738638032Speter backlogs under some circumstances. This is probably a 738738032Speter good option if you have high speed links or don't do lots 738838032Speter of ``batch'' messages, but less good if you are using 738938032Speter something like PPP on a 14.4 modem. Based on code 739038032Speter contributed by Roy Mongiovi of Georgia Tech (my main 739138032Speter contribution was to make it configurable). 739238032Speter Save i-number of df file in qf file to simplify rebuilding of queue 739338032Speter after disastrous disk crash. Suggested by Kyle Jones of 739438032Speter UUNET; closely based on code from KJS DECWRL code written 739538032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 739638032Speter are NOT back compatible with 8.6 -- that is, you can convert 739738032Speter from 8.6 to 8.7, but not the other direction. 739838032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 739938032Speter route-addrs in envelopes; this is because in some cases 740038032Speter they can be sent to the shell, which interprets them as 740138032Speter I/O redirection. 740238032Speter Don't include error file (option E) with return-receipts; this 740338032Speter can be confusing. 740438032Speter Don't send "Warning: cannot send" messages to owner-* or 740538032Speter *-request addresses. Suggested by Christophe Wolfhugel 740638032Speter of the Institut Pasteur, Paris. 740738032Speter Allow -O command line flag to set long form options. 740838032Speter Add "MinQueueAge" option to set the minimum time between attempts 740938032Speter to run the queue. For example, if the queue interval 741038032Speter (-q value) is five minutes, but the minimum queue age 741138032Speter is fifteen minutes, jobs won't be tried more often than 741238032Speter once every fifteen minutes. This can be used to give 741338032Speter you more responsiveness if your delivery mode is set to 741438032Speter queue-only. 741538032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 741638032Speter :include: and .forward files. 741738032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 741838032Speter key field name, the value field name, and the field 741938032Speter delimiter. The field delimiter can be a single character 742038032Speter or the sequence "\t" or "\n" for tab or newline. 742138032Speter These are for use by NIS+ and similar access methods. 742238032Speter Change maps to always strip quotes before lookups; the -q flag 742343730Speter turns off this behavior. Suggested by Motonori Nakamura. 742438032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 742538032Speter key and value field names respectively. Code donated by 742638032Speter Sun Microsystems. 742738032Speter Add "hesiod" map class. The "file name" is used as the 742838032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 742938032Speter first value found for the match. Code donated by Scott 743038032Speter Hutton of Indiana University. 743138032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 743238032Speter specify the name of the property that is searched as the 743338032Speter key and a -v flag to specify the name of the property that 743438032Speter is returned as the value (defaults to "members"). The 743538032Speter default map is "/aliases". Some code based on code 743638032Speter contributed by Robert La Ferla of Hot Software. 743738032Speter Add "text" map class. This does slow, linear searches through 743838032Speter text files. The -z flag specifies a column delimiter 743938032Speter (defaults to any sequence of white space), the -k flag 744038032Speter sets the key column number, and the -v flag sets the 744138032Speter value column number. Lines beginning with `#' are treated 744238032Speter as comments. 744338032Speter Add "program" map class to execute arbitrary programs. The search 744438032Speter key is presented as the last argument; the output is one 744538032Speter line read from the programs standard output. Exit statuses 744638032Speter are from sysexits.h. 744738032Speter Add "sequence" map class -- searches maps in sequence until it 744838032Speter finds a match. For example, the declarations: 744938032Speter Kmap1 ... 745038032Speter Kmap2 ... 745138032Speter Kmapseq sequence map1 map2 745238032Speter defines a map "mapseq" that first searches map1; if the 745338032Speter value is found it is returned immediately, otherwise 745438032Speter map2 is searched and the value returned. 745538032Speter Add "switch" map class. This is much like "sequence" except that 745638032Speter the ordering is fetched from an external file, usually 745738032Speter the system service switch. The parameter is the name of 745838032Speter the service to switch on, and the maps that it will use 745938032Speter are the name of the switch map followed by ".service_type". 746038032Speter For example, if the declaration of the map is 746138032Speter Ksample switch hosts 746238032Speter and the system service switch specifies that hosts are 746338032Speter looked up using dns and nis in that order, then this is 746438032Speter equivalent to 746538032Speter Ksample sequence sample.dns sample.nis 746638032Speter The subordinate maps (sample.*) must already be defined. 746738032Speter Add "user" map class -- looks up users using getpwnam. Takes a 746838032Speter "-v field" flag on the definition that tells what passwd 746938032Speter entry to return -- legal values are name, passwd, uid, gid, 747038032Speter gecos, dir, and shell. Generally expected to be used with 747138032Speter the -m (matchonly) flag. 747238032Speter Add "bestmx" map class -- returns the best MX value for the host 747338032Speter listed as the value. If there are several "best" MX records 747438032Speter for this host, one will be chosen at random. 747538032Speter Add "userdb" map class -- looks up entries in the user database. 747638032Speter The "file name" is actually the tag that will be used, 747738032Speter typically "mailname". If there are multiple entries 747838032Speter matching the name, the one chosen is undefined. 747938032Speter Add multiple queue timeouts (both return and warning). These are 748038032Speter set by the Precedence: or Priority: header fields to one of 748138032Speter three values. If a Priority: is set and has value "normal", 748264562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 748338032Speter used. If no priority is set, the Precedence: is consulted; 748438032Speter if negative, non-urgent timeouts are used; if greater than 748538032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 748638032Speter are used. The timeouts are set by setting the six timeouts 748738032Speter queue{warn,return}.{urgent,normal,non-urgent}. 748838032Speter Fix problem when a mail address is resolved to a $#error mailer 748938032Speter with a temporary failure indication; it works in SMTP, 749038032Speter but when delivering locally the mail is silently discarded. 749138032Speter This patch, from Kyle Jones of UUNET, bounces it instead 749238032Speter of queueing it (queueing is very hard). 749338032Speter When using /etc/hosts or NIS-style lookups, don't assume that 749438032Speter the first name in the list is the best one -- instead, 749538032Speter search for the first one with a dot. For example, if 749638032Speter an /etc/hosts entry reads 749738032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 749838032Speter this change will use the second name as the canonical 749938032Speter machine name instead of the initial, unqualified name. 750038032Speter Change dequote map to replace spaces in quoted text with a value 750138032Speter indicated by the -s flag on the dequote map definition. 750238032Speter For example, ``Mdequote dequote -s_'' will change 750338032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 750438032Speter quoted (because of the space character). Suggested by Dan 750538032Speter Oscarsson for use in X.400 addresses. 750638032Speter Implement long macro names as ${name}; long class names can 750738032Speter be similarly referenced as $={name} and $~{name}. 750838032Speter Definitions are (e.g.) ``D{name}value''. Names that have 750938032Speter a leading lower case letter or punctuation characters are 751038032Speter reserved for internal use by sendmail; i.e., config files 751138032Speter should use names that begin with a capital letter. Based 751238032Speter on code contributed by Dan Oscarsson. 751338032Speter Fix core dump if getgrgid returns a null group list (as opposed 751438032Speter to an empty group list, that is, a pointer to a list 751538032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 751638032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 751738032Speter failed, it called syserr which called newstr which called 751838032Speter xalloc.... The newstr is now avoided for "panic" messages. 751938032Speter Reported by Stuart Kemp of James Cook University. 752038032Speter Improve connection cache timeouts; previously, they were not even 752138032Speter checked if you were delivering to anything other than an 752238032Speter IPC-connected host, so a series of (say) local mail 752338032Speter deliveries could cause cached connections to be open 752438032Speter much longer than the specified timeout. 752538032Speter If an incoming message exceeds the maximum message size, stop 752638032Speter writing the incoming bytes to the queue data file, since 752738032Speter this can fill your mqueue partition -- this is a possible 752838032Speter denial-of-service attack. 752938032Speter Don't reject all numeric local user names unless HESIOD is 753038032Speter defined. It turns out that Posix allows all-numeric 753138032Speter user names. Fix from Tony Sanders of BSDI. 753238032Speter Add service switch support. If the local OS has a service 753338032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 753438032Speter on DEC systems) that will be used; otherwise, it falls back 753538032Speter to using a local mechanism based on the ServiceSwitchFile 753638032Speter option (default: /etc/service.switch). For example, if the 753738032Speter service switch lists "files" and "nis" for the aliases 753838032Speter service, that will be the default lookup order. the "files" 753938032Speter ("local" on DEC) service type expands to any alias files 754038032Speter you listed in the configuration file, even if they aren't 754138032Speter actually file lookups. 754238032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 754338032Speter variable which tells whether or not DNS should be considered 754438032Speter canonical. This is now determined based on whether or not 754538032Speter "dns" is in the service list for "hosts". 754638032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 754738032Speter Status Notifications). DSN notifications override 754838032Speter Return-Receipt-To: headers, which are bogus anyhow -- 754938032Speter support for them has been removed. 755038032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 755138032Speter definitions to define the types used in DSN returns for 755238032Speter MTA names, addresses, and diagnostics respectively. 755338032Speter Extend heuristic to force running in ESMTP mode to look for the 755438032Speter five-character string "ESMTP" anywhere in the 220 greeting 755538032Speter message (not just the second line). This is to provide 755638032Speter better compatibility with other ESMTP servers. 755738032Speter Print sequence number of job when running the queue so you can 755838032Speter easily see how much progress you have made. Suggested 755938032Speter by Peter Wemm of DIALix. 756038032Speter Map newlines to spaces in logged message-ids; some versions of 756138032Speter syslog truncate the rest of the line after newlines. 756238032Speter Suggested by Fletcher Mattox of U. Texas. 756338032Speter Move up forking for job runs so that if a message is split into 756438032Speter multiple envelopes you don't get "fork storms" -- this 756538032Speter also improves the connection cache utilization. 756638032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 756738032Speter the purposes of refusing to send error returns. Suggested 756838032Speter by Motonori Nakamura of Ritsumeikan University. 756938032Speter Relax rules on when a file can be written when referenced from 757038032Speter the aliases file: use the default uid/gid instead of the 757138032Speter real uid/gid. This allows you to create a file owned by 757238032Speter and writable only by the default uid/gid that will work 757390792Sgshapiro all the time (without having the set-user-ID bit set). Change 757438032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 757538032Speter Microsystems. 757638032Speter Add "DialDelay" option (no short name) to provide an "extra" 757738032Speter delay for dial on demand systems. If this is non-zero 757838032Speter and a connect fails, sendmail will wait this long and 757938032Speter then try again. If it takes longer than the kernel 758038032Speter timeout interval to establish the connection, this 758138032Speter option can give the network software time to establish 758238032Speter the link. The default units are seconds. 758338032Speter Move logging of sender information to be as early as possible; 758438032Speter previously, it could be delayed a while for SMTP mail 758538032Speter sent to aliases. Suggested by Brad Knowles of the 758638032Speter Defense Information Systems Agency. 758738032Speter Call res_init() before setting RES_DEBUG; this is required by 758838032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 758938032Speter the National Computer Security Center. 759038032Speter Add xdelay= field in logs -- this is a transaction delay, telling 759138032Speter you how long it took to deliver to this address on the 759238032Speter last try. It is intended to be used for sorting mailing 759338032Speter lists to favor "quick" addresses. Provided for use by 759438032Speter the mailprio scripts (see below). 759538032Speter If a map cannot be opened, and that map is non-optional, and 759638032Speter an address requires that map for resolution, queue the 759738032Speter map instead of bouncing it. This involves creating a 759838032Speter pseudo-class of maps called "bogus-map" -- if a required 759938032Speter map cannot be opened, the class is changed to bogus-map; 760038032Speter all queries against bogus-map return "tempfail". The 760138032Speter bogus-map class is not directly accessible. A sample 760238032Speter implementation was donated by Jem Taylor of Glasgow 760338032Speter University Computing Service. 760438032Speter Fix a possible core dump when mailing to a program that talks 760538032Speter SMTP on its standard input. Fix from Keith Moore of 760638032Speter the University of Kentucky. 760738032Speter Make it possible to resolve filenames to $#local $: @ /filename; 760838032Speter previously, the "@" would cause it to not be recognized 760938032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 761038032Speter Accept a -1 signal to re-exec the daemon. This only works if 761138032Speter argv[0] is a full path to sendmail. 761238032Speter Fix bug in "addr=..." field in O option on little-endian machines 761338032Speter -- the network number wasn't being converted to network 761438032Speter byte order. Patch from Kurt Lidl of Pix Technologies 761538032Speter Corporation. 761638032Speter Pre-initialize the resolver early on; this is to avoid a bug with 761738032Speter BIND 4.9.3 that can cause the _res.retry field to get 761838032Speter reset to zero, causing all name server lookups to time 761938032Speter out. Fix from Matt Day of Artisoft. 762038032Speter Restore T line (trusted users) in config file -- but instead of 762138032Speter locking out the -f flag, they just tell whether or not 762238032Speter an X-Authentication-Warning: will be added. This really 762338032Speter just creates new entries in class 't', so "Ft/file/name" 762438032Speter can be used to read trusted user names from a file. 762538032Speter Trusted users are also allowed to execute programs even 762638032Speter if they have a shell that isn't in /etc/shells. 762738032Speter Improve NEWDB alias file rebuilding so it will create them 762838032Speter properly if they do not already exist. This had been 762938032Speter a MAYBENEXTRELEASE feature in 8.6.9. 763038032Speter Check for @:@ entry in NIS maps before starting up to avoid 763138032Speter (but not prevent, sigh) race conditions. This ought to 763238032Speter be handled properly in ypserv, but isn't. Suggested by 763338032Speter Michael Beirne of Motorola. 763438032Speter Refuse connections if there isn't enough space on the filesystem 763538032Speter holding the queue. Contributed by Robert Dana of Wolf 763638032Speter Communications. 763738032Speter Skip checking for directory permissions in the path to a file 763838032Speter when checking for file permissions iff setreuid() 763938032Speter succeeded -- it is unnecessary in that case. This avoids 764038032Speter significant performance problems when looking for .forward 764138032Speter files. Based on a suggestion by Win Bent of USC. 764238032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 764338032Speter arbitrary ruleset number assigned or "Sname = integer" 764438032Speter to assign a specific ruleset number. Reference is 764538032Speter $>name_or_number. Names can be composed of alphas, digits, 764638032Speter underscore, or hyphen (first character must be non-numeric). 764738032Speter Allow -o flag on AliasFile lines to make the alias file optional. 764838032Speter From Bryan Costales of ICSI. 764938032Speter Add NoRecipientAction option to handle the case where there is 765038032Speter no legal recipient header in the message. It can take 765138032Speter on values: 765238032Speter None Leave the message as is. The 765338032Speter message will be passed on even 765438032Speter though it is in technically 765538032Speter illegal syntax. 765638032Speter Add-To Add a To: header with any 765738032Speter recipients that it can find from 765838032Speter the envelope. This risks exposing 765938032Speter Bcc: recipients. 766038032Speter Add-Apparently-To Add an Apparently-To: header. This 766138032Speter has almost no redeeming social value, 766238032Speter and is provided only for back 766338032Speter compatibility. 766438032Speter Add-To-Undisclosed Add a header reading 766538032Speter To: undisclosed-recipients:; 766638032Speter which will have the effect of 766738032Speter making the message legal without 766838032Speter exposing Bcc: recipients. 766938032Speter Add-Bcc To add an empty Bcc: header. 767038032Speter There is a chance that mailers down 767138032Speter the line will delete this header, 767238032Speter which could cause exposure of Bcc: 767338032Speter recipients. 767438032Speter The default is NoRecipientAction=None. 767538032Speter Truncate (rather than delete) Bcc: lines in the header. This 767638032Speter should prevent later sendmails (at least, those that don't 767738032Speter themselves delete Bcc:) from considering this message to 767838032Speter be non-conforming -- although it does imply that non-blind 767938032Speter recipients can see that a Bcc: was sent, albeit not to whom. 768038032Speter Add SafeFileEnvironment option. If declared, files named as delivery 768138032Speter targets must be regular files in addition to the regular 768238032Speter checks. Also, if the option is non-null then it is used as 768338032Speter the name of a directory that is used as a chroot(2) 768438032Speter environment for the delivery; the file names listed in an 768538032Speter alias or forward should include the name of this root. 768638032Speter For example, if you run with 768738032Speter O SafeFileEnvironment=/arch 768838032Speter then aliases should reference "/arch/rest/of/path". If a 768938032Speter value is given, sendmail also won't try to save to 769038032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 769138032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 769238032Speter Support -A flag for alias files; this will comma concatenate like 769338032Speter entries. For example, given the aliases: 769438032Speter list: member1 769538032Speter list: member2 769638032Speter and an alias file declared as: 769738032Speter OAhash:-A /etc/aliases 769838032Speter the final alias inserted will be "list: member1,member2"; 769938032Speter without -A you will get an error on the second and subsequent 770038032Speter alias for "list". Contributed by Bryan Costales of ICSI. 770138032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 770238032Speter Fix a problem that could cause very long addresses to core dump in 770338032Speter some special circumstances. Problem pointed out by Allan 770438032Speter Johannesen. 770538032Speter (Internal change.) Change interface to expand() (macro expansion) 770638032Speter to be simpler and more consistent. 770738032Speter Delete check for funny qf file names. This didn't really give 770838032Speter any extra security and caused some people some problems. 770938032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 771038032Speter at compile time.) Suggested by Kyle Jones of UUNET. 771138032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 771238032Speter merge with DSN code; this is simpler and more consistent. 771338032Speter This may affect some people who have written their own 771438032Speter checkcompat() routine. 771538032Speter (Internal change.) Eliminate `D' line in qf file. The df file 771638032Speter is now assumed to be the same name as the qf file (with 771738032Speter the `q' changed to a `d', of course). 771838032Speter Avoid forking for delivery if all recipient mailers are marked as 771938032Speter "expensive" -- this can be a major cost on some systems. 772038032Speter Essentially, this forces sendmail into "queue only" mode 772138032Speter if all it is going to do is queue anyway. 772238032Speter Avoid sending a null message in some rather unusual circumstances 772338032Speter (specifically, the RCPT command returns a temporary 772438032Speter failure but the connection is lost before the DATA 772538032Speter command). Fix from Scott Hammond of Secure Computing 772638032Speter Corporation. 772738032Speter Change makesendmail to use a somewhat more rational naming scheme: 772838032Speter Makefiles and obj directories are named $os.$rel.$arch, 772938032Speter where $os is the operating system (e.g., SunOS), $rel is 773038032Speter the release number (e.g., 5.3), and $arch is the machine 773138032Speter architecture (e.g., sun4). Any of these can be omitted, 773238032Speter and anything after the first dot in a release number can 773338032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 773438032Speter version used $os.$arch.$rel and was rather less general. 773538032Speter Change makesendmail to do a "make depend" in the target directory 773638032Speter when it is being created. This involves adding an empty 773738032Speter "depend:" entry in most Makefiles. 773838032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 773938032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 774038032Speter of the Finnish Meteorological Institute. 774138032Speter Fix problem that could cause multiple responses to DATA command 774238032Speter on header syntax errors (e.g., lines beginning with colons). 774338032Speter Problem noted by Jens Thomassen of the University of Oslo. 774438032Speter Don't let null bytes in headers cause truncation of the rest of 774538032Speter the header. 774638032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 774738032Speter Increase timeouts on message data puts to allow time for receivers 774838032Speter to canonify addresses in headers on the fly. This is still 774938032Speter a rather ugly heuristic. From Motonori Nakamura. 775038032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 775138032Speter records are not used when canonifying names, and when MX 775238032Speter lookups are done for addressing they must be fully 775338032Speter qualified. This is useful if you have a wildcard MX record, 775438032Speter although it may cause other problems. In general, don't use 775538032Speter wildcard MX records. Patch from Motonori Nakamura. 775638032Speter Eliminate default two-line SMTP greeting message. Instead of 775738032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 775838032Speter is added between the first and second word of the first 775938032Speter line of the greeting message (i.e., immediately after the 776038032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 776138032Speter compile flag. Old sendmails won't see the ESMTP, but that's 776238032Speter acceptable because SIZE was the only useful extension that 776338032Speter old sendmails understand. 776438032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 776538032Speter invoked state dumps. From Masaharu Onishi. 776638032Speter Allow on-line comments in .forward and :include: files; they are 776738032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 776838032Speter is a space or a tab. This is intended for native 776938032Speter representation of non-ASCII sets such as Japanese, where 777038032Speter existing encodings would be unreadable or would lose 777138032Speter data -- for example, 777238032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 777338032Speter (romanized/less information) 777438032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 777538032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 777638032Speter (with MIME encoding, not human readable) 777738032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 777838032Speter (native encoding with ISO-2022-JP) 777938032Speter The last form is human readable in the Japanese environment. 778038032Speter Based on a fix from (surprise!) Motonori Nakamura. 778138032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 778238032Speter messages to that host; these are most frequently associated 778338032Speter with addresses rather than the host, with the exception of 778438032Speter 421 (service shutting down). The effect was to cause queues 778538032Speter to sometimes take an excessive time to flush. Reported by 778638032Speter Robert Sargent of Southern Geographics Technologies and 778738032Speter Eric Prestemon of American University. 778838032Speter Add Nice=N mailer option to set the niceness at which a mailer will 778938032Speter run. This is actually a relative niceness (that is, an 779038032Speter increment on the background value). 779138032Speter Log queue runs that are skipped due to high loads. They are logged 779238032Speter at LOG_INFO priority iff the log level is > 8. Contributed 779338032Speter by Bruce Nagel of Data General. 779438032Speter Allow the error mailer to accept a DSN-style error status code 779538032Speter instead of an sysexits status code in the host part. 779638032Speter Anything with a dot will be interpreted as a DSN-style code. 779738032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 779838032Speter to encode characters that might be munged by an EBCDIC system 779938032Speter in addition to the set required by RFC 1521. The additional 780038032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 780138032Speter (Think of "IBM 360" as the mnemonic for this flag.) 780238032Speter Change check for mailing to files to look for a pathname of [FILE] 780338032Speter rather than looking for the mailer named *file*. The mapping 780438032Speter of leading slashes still goes to the *file* mailer. This 780538032Speter allows you to implement the *file* mailer as a separate 780638032Speter program, for example, to insert a Content-Length: header 780738032Speter or do special security policy. However, note that the usual 780838032Speter initial checking for the file permissions is still done, and 780938032Speter the program in question needs to be very careful about how 781038032Speter it does the file write to avoid security problems. 781138032Speter Be able to read ~root/.forward even if the path isn't accessible to 781238032Speter regular users. This is disrecommended because sendmail 781338032Speter sometimes does not run as root (e.g., when an unsafe option 781438032Speter is specified on the command line), but should otherwise be 781538032Speter safe because .forward files must be owned by the user for 781638032Speter whom mail is being forwarded, and cannot be a symbolic link. 781738032Speter Suggested by Forrest Aldrich of Wang Laboratories. 781838032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 781938032Speter file. This is used for canonifying hostnames when the 782038032Speter service type is "files". 782138032Speter Implement programs on F (read class from file) line. The syntax is 782238032Speter Fc|/path/to/program to read the output from the program 782338032Speter into class "c". 782438032Speter Probe the network interfaces to find alternate names for this 782538032Speter host. Requires the SIOCGIFCONF ioctl call. Code 782638032Speter contributed by SunSoft. 782738032Speter Add "E" configuration line to set or propagate environment 782838032Speter variables into children. "E<envar>" will propagate 782938032Speter the named variable from the environment when sendmail 783038032Speter was invoked into any children it calls; "E<envar>=<value>" 783138032Speter sets the named variable to the indicated value. Any 783238032Speter variables not explicitly named will not be in the child 783338032Speter environment. However, sendmail still forces an 783438032Speter "AGENT=sendmail" environment variable, in part to enforce 783538032Speter at least one environment variable, since many programs and 783638032Speter libraries die horribly if this is not guaranteed. 783738032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 783838032Speter alias databases -- new algorithm looks for the substring 783938032Speter "/yp/" in the file name. This is more portable and involves 784038032Speter less overhead. Suggested by Motonori Nakamura. 784138032Speter Dynamically allocate the queue work list so that you don't lose 784238032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 784338032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 784438032Speter should not need to be changed) and the MaxQueueRunSize option, 784538032Speter which is the absolute maximum number of jobs that will ever 784638032Speter be handled in a single queue run. Based on code contributed 784738032Speter by Brian Coan of the Institute for Global Communications. 784838032Speter Log message when a message is dropped because it exceeds the maximum 784938032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 785038032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 785138032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 785238032Speter of Mark G. Thomas Consulting. 785338032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 785438032Speter OS-dependent defines). The old semantic of -d0.1 to not 785538032Speter run the daemon in background has been moved to -d99.100, 785638032Speter and the old 52.5 flag (to avoid disconnect() from closing 785738032Speter all output files) has been moved to 52.100. This makes 785838032Speter things more consistent (flags below .100 don't change 785938032Speter semantics) and separates out the backgrounding so that 786038032Speter it doesn't happen automatically on other unrelated debugging 786138032Speter flags. 786238032Speter If -t is used but no addresses are found in the header, give an 786338032Speter error message rather than just doing nothing. Fix from 786438032Speter Motonori Nakamura. 786538032Speter On systems (like SunOS) where the effective gid is not necessarily 786638032Speter included in the group list returned by getgroups(), the 786738032Speter `restrictmailq' option could sometimes cause an authorized 786838032Speter user to not be able to use `mailq'. Fix from Charles Hannum 786938032Speter of MIT. 787038032Speter Allow symbolic service names for [IPC] mailers. Suggested by 787138032Speter Gerry Magennis of Logica International. 787238032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 787338032Speter when running DNS. For example, if the name FTP.Foo.ORG is 787438032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 787538032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 787638032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 787738032Speter This is technically illegal under RFC 822 and 1123, but the 787838032Speter IETF is moving toward legalizing it. Note that turning on 787938032Speter this option is not sufficient to guarantee that a downstream 788038032Speter neighbor won't rewrite the address for you. 788138032Speter Add "-m" flag to makesendmail script -- this tells you what object 788238032Speter directory and Makefile it will use, but doesn't actually do 788338032Speter the make. 788438032Speter Do some additional checking on the contents of the qf file to try 788538032Speter to detect attacks against the qf file. In particular, 788638032Speter abort on any line beginning "From ", and add an "end of 788738032Speter file" line -- any data after that line is prohibited. 788838032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 788938032Speter choices. This can be overridden in the Makefile by using 789038032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 789138032Speter (to the extent that we know it) or by defining 789238032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 789338032Speter sendmail 8 to have more consistent installation instructions. 789438032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 789538032Speter of Sun Microsystems. 789638032Speter Improved symbol table hash function from Eric Wassenaar. This one 789738032Speter is at least 50% faster. 789838032Speter Fix problem that didn't notice that timeout on file open was a 789938032Speter transient error. Fix from Larry Parmelee of Cornell 790038032Speter University. 790138032Speter Allow comments (lines beginning with a `#') in files read for 790238032Speter classes. Suggested by Motonori Nakamura. 790338032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 790438032Speter of dropping out entirely. This makes testing some of the 790538032Speter name server lookups easier to deal with when there are 790638032Speter hung servers. From Motonori Nakamura. 790738032Speter Add new ${opMode} macro that is set to the current operation mode 790838032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 790938032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 791038032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 791138032Speter Kind of like queue-only mode (Odq) except it tries to avoid 791238032Speter any external service requests; for dial-on-demand hosts that 791338032Speter want to minimize DNS lookups when mail is being queued. For 791438032Speter this to work you will also have to make sure that gethostbyname 791538032Speter of your local host name does not do a DNS lookup. 791638032Speter Improved handling of "out of space" conditions from John Myers of 791738032Speter Carnegie Mellon. 791838032Speter Improved security for mailing to files on systems that have fchmod(2) 791938032Speter support. 792038032Speter Improve "cannot send message for N days" message -- now says "could 792138032Speter not send for past N days". Suggested by Tom Moore of AT&T 792238032Speter Global Information Solutions. 792338032Speter Less misleading Subject: line on messages sent to postmaster only. 792438032Speter From Motonori Nakamura. 792538032Speter Avoid duplicate error messages on bad command line flags. From 792638032Speter Motonori Nakamura. 792738032Speter Better error message for case where ruleset 0 falls off the end 792838032Speter or otherwise does not resolve to a canonical triple. 792938032Speter Fix a problem that could cause multiple bounce messages if a bad 793038032Speter address was sent along with a good address to an SMTP 793138032Speter site where that SMTP site returned a 4yz code in response 793238032Speter to the final dot of the data. Problem reported by David 793338032Speter James of British Telecom. 793438032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 793538032Speter from Alexander Dupuy of System Management ARTS. 793638032Speter Delete duplicates in MX lists -- believe it or not, there are sites 793738032Speter that list the same host twice in an MX list. This deletion 793838032Speter only works on adjacent preferences, so an MX list that 793938032Speter had A=5, B=10, A=15 would leave both As, but one that had 794038032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 794138032Speter just in case there is something weird I haven't thought of. 794238032Speter Suggested by Barry Shein of Software Tool & Die. 794338032Speter SECURITY: .forward files cannot be symbolic links. If they are, 794438032Speter a bad guy can read your private files. 794538032Speter PORTABILITY FIXES: 794638032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 794738032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 794838032Speter University.

This means that the 796238032Speter sizeof operator returns only multiples of 8. 796338032Speter This requires adaptation of code that really 796438032Speter deals with 32 bit or 16 bit fields, such as IP 796538032Speter addresses or nameserver fields.'' 796638032Speter DG/UX 5.4.3 from Mark T.

This can 805138032Speter be used as an alternative to /bin/sh for the "prog" mailer, 805238032Speter giving the local administrator more control over what 805338032Speter programs can be run from sendmail. 805438032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 805538032Speter part of the release proper, and isn't fully supported; in 805638032Speter particular, it does not run on System V based systems and 805738032Speter never will. 805838032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 805938032Speter to allow rmail to compile on systems that don't have 806038032Speter function prototypes and systems that don't have snprintf. 806138032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 806238032Speter lists by transaction delay times so that addresses that 806338032Speter respond quickly get sent first. This is to prevent very 806438032Speter sluggish servers from delaying other peoples' mail. 806538032Speter Contributed by Tony Sanders of BSDI. 806638032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 806738032Speter of BSDI. This has a lot of comments to help people out. 806838032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 806938032Speter put this on the m4 command line. On GNU m4 (which 807038032Speter supports the __file__ primitive) you can run m4 in an 807138032Speter arbitrary directory -- use either: 807238032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 807338032Speter or 807438032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 807538032Speter On other versions of m4 that don't support __file__, you 807638032Speter can use: 807738032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 807838032Speter (Note the trailing slash on the _CF_DIR_ definition.) 807938032Speter Old versions of m4 will default to _CF_DIR_=.. for back 808038032Speter compatibility. 808138032Speter CONFIG: fix mail from <> so it will properly convert to 808238032Speter MAILER-DAEMON on local addresses. 808338032Speter CONFIG: fix code that was supposed to catch colons in host 808438032Speter names. Problem noted by John Gardiner Myers of CMU. 808538032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 808638032Speter From Paul Riddle of the University of Maryland, Baltimore 808738032Speter County. 808838032Speter CONFIG: Catch and reject "." as a host address. 808938032Speter CONFIG: Generalize domaintable to look up all domains, not 809038032Speter just unqualified ones. 809138032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 809238032Speter was never used and didn't work anyway. 809338032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 809438032Speter and d on all mailers in the UUCP class. 809538032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 809638032Speter look for an alias for "user+detail", then for "user+*", and 809738032Speter finally for "user". This is intended for forwarding mail 809838032Speter for system aliases such as root and postmaster to a 809938032Speter centralized hub. 810038032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 810138032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 810238032Speter The F=8 flag is also set on the "relay" mailer, since 810338032Speter this is expected to be another sendmail. 810438032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 810538032Speter the name of the UUCP_RELAY -- in some cases, this is the 810638032Speter wrong value (e.g., when we have local UUCP connections), 810738032Speter and this can create unreplyable addresses. From Chip 810838032Speter Rosenthal of Unicom. 810938032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 811064562Sgshapiro Received: header inserted into all messages. Suggested by 811138032Speter Gary Mills of the University of Manitoba. 811238032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 811343730Speter to get the old behavior. I did this upon observing 811438032Speter that almost everyone needed this feature, and that the 811538032Speter concept I was trying to make happen didn't work with 811638032Speter some user agents anyway. FEATURE(notsticky) still works, 811738032Speter but it is a no-op. 811838032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 811938032Speter names are sent, rather than immediately diagnosing them 812038032Speter as User Unknown. 812138032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 812238032Speter and RELAY_MAILER_ARGS to set the arguments for the 812338032Speter indicated mailers. All default to "IPC $h". Patch from 812438032Speter Larry Parmelee of Cornell University. 812538032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 812638032Speter on the client side" and F=P to get an appropriate 812738032Speter return-path. From Kimmo Suominen. 812838032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 812938032Speter as the local mailer. For addresses of the form "user+detail" 813038032Speter the "detail" part is passed to procmail via the -a flag. 813138032Speter Contributed by Kimmo Suominen. 813238032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 813338032Speter use from mailertables. This lets you execute arbitrary 813438032Speter procmail scripts. Contributed by Kimmo Suominen. 813538032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 813638032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 813738032Speter Paul Southworth of CICNet Systems Support. 813838032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 813938032Speter This causes the null return path to be rewritten as 814038032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 814138032Speter From Michael Hohmuth of Technische Universitat Dresden. 814238032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 814338032Speter list us as the best possible MX record to be treated as 814438032Speter though they were local (essentially, assume that they 814538032Speter are included in $=w). This can cause additional DNS 814638032Speter traffic, but is easier to administer if this fits your 814738032Speter local model. It does not work reliably if there are 814838032Speter multiple hosts that share the best MX preference. 814938032Speter Code contributed by John Oleynick of Rutgers. 815038032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 815138032Speter SHell) instead of /bin/sh as the program used for delivery 815238032Speter to programs. If an argument is included, it is used as 815338032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 815438032Speter assumed. 815538032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 815638032Speter size of messages to the local and procmail mailers 815738032Speter respectively. Contributed by Brad Knowles of the Defense 815838032Speter Information Systems Agency. 815938032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 816038032Speter (just like text outside of angle brackets) in order to 816138032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 816238032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 816338032Speter any real systems any more) and tweak the DOMAIN macro 816438032Speter so that it is less likely that users will accidentally use 816538032Speter the Berkeley defaults. Also, create some generic files 816638032Speter that really can be used in the real world. 816738032Speter CONFIG: Add new configuration macros to set character sets for 816838032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 816938032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 817038032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 817138032Speter The old name will still be accepted for a while at least. 817238032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 817338032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 817438032Speter As with all relays, it can be ``mailer:hostname''. Suggested 817538032Speter by Scott Hutton. 817638032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 817738032Speter by Barb Dijker of Labyrinth Computer Services. 817838032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 817938032Speter performance for large alias files, and this confused many 818038032Speter people. 818138032Speter CONFIG: Add confCF_VERSION to append local information to the 818238032Speter configuration version number displayed during SMTP startup. 818338032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 818438032Speter would only work when locally addressed. Fix from 818538032Speter Edvard Tuinder of Cistron Internet Services. 818638032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 818743730Speter "n" (CheckAliases) is set when rebuilding alias database. 818838032Speter Based on code contributed by Claude Marinier. 818938032Speter CONFIG: Allow mailertable to have values of the form 819038032Speter ``error:code message''. The ``code'' is a status code 819138032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 819238032Speter Contributed by David James <dwj@agw.bt.co.uk>. 819338032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 819438032Speter sender domains that will be replaced with the masquerade name. 819538032Speter These domains will not be treated as local, but if mail passes 819638032Speter through with sender addresses in those domains they will be 819738032Speter replaced by the masquerade name. These can also be specified 819838032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 819938032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 820038032Speter as well as the header. Substantial improvements to this 820138032Speter code were contributed by Per Hedeland. 820238032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 820338032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 820438032Speter by Kimmo Suominen. 820538032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 820638032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 820738032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 820838032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 820938032Speter UUCP addressing.

832064562Sgshapiro8.6.12/8.6.12 1995/03/28 832138032Speter Fix to IDENT code (it was getting the size of the reply buffer 832238032Speter too small, so nothing was ever accepted). Fix from several 832338032Speter people, including Allan Johannesen, Shane Castle of the 832438032Speter Boulder County Information Services, and Jeff Smith of 832538032Speter Warwick University (all arrived within a few hours of 832638032Speter each other!). 832738032Speter Fix a problem that could cause large jobs to run out of 832838032Speter file descriptors on systems that use vfork() rather 832938032Speter than fork(). 833038032Speter 833164562Sgshapiro8.6.11/8.6.11 1995/03/08 833238032Speter The ``possible attack'' message would be logged more often 833338032Speter than necessary if you are using Pine as a user agent. 833438032Speter The wrong host would be reported in the ``possible attack'' 833538032Speter message when attempted from IDENT. 833638032Speter In some cases the syslog buffer could be overflowed when 833738032Speter reporting the ``possible attack'' message. This can 833838032Speter cause denial of service attacks. Truncate the message 833938032Speter to 80 characters to prevent this problem. 834038032Speter When reading the IDENT response a loop is needed around the 834138032Speter read from the network to ensure that you don't get 834238032Speter partial lines. 834338032Speter Password entries without any shell listed (that is, a null 834438032Speter shell) wouldn't match as "ok". Problem noted by 834538032Speter Rob McMahon. 834638032Speter When running BIND 4.9.x a problem could occur because the 834738032Speter _res.options field is initialized differently than it 834838032Speter was historically -- this requires that sendmail call 834938032Speter res_init before it tweaks any bits. 835038032Speter Fix an incompatibility in openxscript() between the file open mode 835138032Speter and the stdio mode passed to fdopen. This caused UnixWare 835238032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 835338032Speter Novell Labs Europe. 835438032Speter Fix problem with static linking of local getopt routine when 835538032Speter using GNU's ld command. Fix from John Kennedy of 835638032Speter Cal State Chico. 835738032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 836038032Speter and Liudvikas Bukys. 836138032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 836238032Speter from Spider Boardman. 836338032Speter CONFIG: No changes (version number only, to keep it in sync 836438032Speter with the binaries). 836538032Speter 836664562Sgshapiro8.6.10/8.6.10 1995/02/10 836738032Speter SECURITY: Diagnose bogus values to some command line flags that 836838032Speter could allow trash to get into headers and qf files. 836938032Speter Validate the name of the user returned by the IDENT protocol. 837038032Speter Some systems that really dislike IDENT send intentionally 837138032Speter bogus information. Problem pointed out by Michael Bushnell 837238032Speter of the Free Software Foundation. Has some security 837338032Speter implications. 837438032Speter Fix a problem causing error messages about DNS problems when 837538032Speter the host name contained a percent sign to act oddly 837638032Speter because it was passed as a printf-style format string. 837738032Speter In some cases this could cause core dumps. 837838032Speter Avoid possible buffer overrun in returntosender() if error 837938032Speter message is quite long. From Fletcher Mattox of the 838038032Speter University of Texas. 838138032Speter Fix a problem that would silently drop "too many hops" error 838238032Speter messages if and only if you were sending to an alias. 838338032Speter From Jon Giltner of the University of Colorado and 838438032Speter Dan Harton of Oak Ridge National Laboratory. 838538032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 838638032Speter set and e->e_message was null. Fix from Bruce Nagel of 838738032Speter Data General. 838838032Speter Fix problem that can still cause df files to be left around 838938032Speter after "hop count exceeded" messages. Fix from Andrew 839038032Speter Chang and Shau-Ping Lo of SunSoft. 839138032Speter Fix a problem that can cause buffer overflows on very long 839238032Speter user names (as might occur if you piped to a program 839338032Speter with a lot of arguments). 839438032Speter Avoid returning an error and re-queueing if the host signature 839538032Speter is null; this can occur on addresses like ``user@.''. 839638032Speter Problem noted by Wesley Craig and the University of 839738032Speter Michigan. 839838032Speter Avoid possible calls to malloc(0) if MCI caching is turned 839938032Speter off. Bug fix from Pierre David of the Laboratoire 840038032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 840138032Speter Universite de Versailles - St Quentin, and Jacky 840238032Speter Thibault. 840338032Speter Make a local copy of the line being sent via senttolist() -- in 840438032Speter some cases, buffers could get trashed by map lookups 840538032Speter causing it to do unexpected things. This also simplifies 840638032Speter some of the map code. 840738032Speter CONFIG: No changes (version number only, to keep it in sync 840838032Speter with the binaries). 840938032Speter 841064562Sgshapiro8.6.9/8.6.9 1994/04/19 841138032Speter Do all mail delivery completely disconnected from any terminal. 841238032Speter This provides consistency with daemon delivery and 841338032Speter may have some security implications. 841438032Speter Make sure that malloc doesn't get called with zero size, 841538032Speter since that fails on some systems. Reported by Ed 841638032Speter Hill of the University of Iowa. 841738032Speter Fix multi-line values for $e (SMTP greeting message). Reported 841838032Speter by Mike O'Connor of Ford Motor Company. 841938032Speter Avoid syserr if no NIS domain name is defined, but the map it 842038032Speter is trying to open is optional. From Win Bent of USC. 842138032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 842238032Speter Hesiod support for UDB from Todd Miller of the University of 842338032Speter Colorado. Use "hesiod" as the service name in the U 842438032Speter option. 842538032Speter Fix a problem that failed to set the "authentic" host name (that 842638032Speter is, the one derived from the socket info) if you called 842738032Speter sendmail -bs from inetd. Based on code contributed by 842838032Speter Todd Miller (this problem was also reported by Guy Helmer 842938032Speter of Dakota State University). This also fixes a related 843038032Speter problem reported by Liudvikas Bukys of the University of 843138032Speter Rochester. 843238032Speter Parameterize "nroff -h" in all the Makefiles so people with 843338032Speter variant versions can use them easily. Suggested by 843438032Speter Peter Collinson of Hillside Systems. 843538032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 843638032Speter spaces between parameters instead of one. Reported by 843738032Speter Valdis Kletnieks of Virginia Tech. 843838032Speter Reduce the number of system calls during message collection by 843938032Speter using global timeouts around the collect() loop. This 844038032Speter code was contributed by Eric Wassenaar. 844138032Speter If the initial hostname name gathering results in a name 844238032Speter without a dot (usually caused by NIS misconfiguration) 844338032Speter and BIND is compiled in, directly access DNS to get 844438032Speter the canonical name. This should make life easier for 844538032Speter Solaris systems. If it still can't be resolved, and 844638032Speter if the name server is listed as "required", try again 844738032Speter in 30 seconds. If that also fails, exit immediately to 844838032Speter avoid bogus "config error: mail loops back to myself" 844938032Speter messages. 845038032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 845138032Speter message to explain how much space was available and 845238032Speter sound a bit less threatening. Suggested by Stan Janet 845338032Speter of the National Institute of Standards and Technology. 845438032Speter If mail is delivered to an alias that has an owner, deliver any 845538032Speter requested return-receipt immediately, and strip the 845638032Speter Return-Receipt-To: header from the subsequent message. 845738032Speter This prevents a certain class of denial of service 845838032Speter attack, arguably gives more reasonable semantics, and 845938032Speter moves things more towards what will probably become a 846038032Speter network standard. Suggested by Christopher Davis of 846138032Speter Kapor Enterprises. 846238032Speter Add a "noreceipts" privacy flag to turn off all return receipts 846338032Speter without recompiling. 846438032Speter Avoid printing ESMTP parameters as part of the error message 846538032Speter if there are errors during parsing. This change is 846638032Speter purely cosmetic. 846738032Speter Avoid sending out error messages during the collect phase of 846838032Speter SMTP; there is an MVS mailer from UCLA that gets 846938032Speter confused by this. Of course, I think it's their bug.... 847038032Speter Check for the $j macro getting undefined, losing a dot, or getting 847138032Speter lost from $=w in the daemon before accepting a connection; 847238032Speter if it is, it dumps state, prints a LOG_ALERT message, 847338032Speter and drops core for debugging. This is an attempt to 847438032Speter track down a bug that I thought was long since gone. 847538032Speter If you see this, please forward the log fragment to 847638032Speter sendmail@sendmail.ORG. 847738032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 847838032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 847938032Speter Wolfhugel. 848038032Speter Instead of trying to truncate the listen queue for the server 848138032Speter SMTP port when the load average is too high, just close 848238032Speter the port completely and reopen it later as needed. 848338032Speter This ensures that the other end gets a quick "connection 848438032Speter refused" response, and that the connection can be 848538032Speter recovered later. In particular, some socket emulations 848638032Speter seem to get confused if you tweak the listen queue 848738032Speter size around and can never start listening to connections 848838032Speter again. The down side is that someone could start up 848938032Speter another daemon process in the interim, so you could 849038032Speter have multiple daemons all not listening to connections; 849138032Speter this could in turn cause the sendmail.pid file to be 849238032Speter incorrect. A better approach might be to accept the 849338032Speter connection and give a 421 code, but that could break 849443730Speter other mailers in mysterious ways and have paging behavior 849538032Speter implications. 849638032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 849738032Speter set debugging on the wrong socket. From Eric Wassenaar. 849838032Speter When creating a df* temporary file, be sure you truncate any 849938032Speter existing data in the file -- otherwise system crashes 850038032Speter and the like could result in extra data being sent. 850138032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 850238032Speter doc directory. This includes some additional 850338032Speter information. 850438032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 850538032Speter of recipient envelope addresses. This should have been 850638032Speter handled by the $&h trick, but broke if people were 850738032Speter mixing domainized and UUCP addresses. They should 850838032Speter probably have converted all the way over to uucp-uudom 850938032Speter instead of uucp-{new,old}, but the failure mode was to 851038032Speter loop the mail, which was bad news. 851138032Speter Portability fixes: 851238032Speter Newer BSDI systems (several people). 851338032Speter Older BSDI systems from Christophe Wolfhugel. 851438032Speter Intergraph CLIX, from Paul Southworth of CICNet. 851538032Speter UnixWare, from Evan Champion. 851638032Speter NetBSD from Adam Glass. 851738032Speter Solaris from Quentin Campbell of the University of 851838032Speter Newcastle upon Tyne. 851938032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 852038032Speter Corporation. 852138032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 852238032Speter SunOS (it has setsid() and setvbuf() calls) from 852338032Speter Jonathan Kamens of OpenVision Technologies. 852438032Speter HP-UX from Tor Lillqvist. 852538032Speter New Files: 852638032Speter src/Makefile.CLIX 852738032Speter src/Makefile.NCR3000 852838032Speter doc/changes/Makefile 852938032Speter doc/changes/changes.me 853038032Speter doc/changes/changes.ps 853138032Speter 853264562Sgshapiro8.6.8/8.6.6 1994/03/21 853338032Speter SECURITY: it was possible to read any file as root using the 853438032Speter E (error message) option. Reported by Richard Jones; 853538032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 853638032Speter 853764562Sgshapiro8.6.7/8.6.6 1994/03/14 853838032Speter SECURITY: it was possible to get root access by using weird 853938032Speter values to the -d flag. Thanks to Alain Durand of 854038032Speter INRIA for forwarding me the notice from the bugtraq 854138032Speter list. 854238032Speter 854364562Sgshapiro8.6.6/8.6.6 1994/03/13 854438032Speter SECURITY: the ability to give files away on System V-based 854538032Speter systems proved dangerous -- don't run as the owner 854638032Speter of a :include: file on a system that allows giveaways. 854738032Speter Unfortunately, this also applies to determining a 854838032Speter valid shell. 854938032Speter IMPORTANT: Previous versions weren't expiring old connections 855038032Speter in the connection cache for a long time under some 855138032Speter circumstances. This could result in resource exhaustion, 855238032Speter both at your end and at the other end. This checks the 855338032Speter connections for timeouts much more frequently. From 855438032Speter Doug Anderson of NCSC. 855538032Speter Fix a glitch that snuck in that caused programs to be run as 855638032Speter the sender instead of the recipient if the mail was 855738032Speter from a local user to another local user. From 855838032Speter Motonori Nakamura of Kyoto University. 855938032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 856038032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 856138032Speter Bryan Costales of ICSI. 856238032Speter Change the method used to declare the "statfs" availability; 856338032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 856438032Speter tweaking in conf.c, there is a single #define called 856538032Speter SFS_TYPE which takes on one of six values (SFS_NONE 856638032Speter for no statfs availability, SFS_USTAT for the ustat(2) 856738032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 856838032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 856938032Speter statfs(2) call with the declarations in <sys/vfs.h>, 857038032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 857138032Speter Fix glitch in NetInfo support that could return garbage if 857238032Speter there was no "/locations/sendmail" property. From 857338032Speter David Meyer of the University of Virginia. 857438032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 857538032Speter to allow Linux to turn it off even though it is a 857638032Speter BSD-like system. 857738032Speter Allow setting of "ident" timeout to zero to turn off the ident 857838032Speter protocol entirely. 857938032Speter Make 7-bit stripping local to a connection (instead of to a 858038032Speter mailer); this allows you to specify that SMTP is a 858138032Speter 7-bit channel, but revert to 8-bit should it advertise 858238032Speter that it supports 8BITMIME. You still have to specify 858338032Speter mailer flag 7 to get this stripping at all. 858438032Speter Improve makesendmail script so it handles more cases automatically. 858538032Speter Tighten up restrictions on taking ownership of :include: files 858638032Speter to avoid problems on systems that allow you to give away 858738032Speter files. 858838032Speter Fix a problem that made it impossible to rebuild the alias 858938032Speter file if it was on a read-only file system. From 859038032Speter Harry Edmon of the University of Washington. 859138032Speter Improve MX randomization function. From John Gardiner Myers 859238032Speter of CMU. 859338032Speter Fix a minor glitch causing a bogus message to be printed (used 859438032Speter %s instead of %d in a printf string for the line number) 859538032Speter when a bad queue file was read. From Harry Edmon. 859638032Speter Allow $s to remain NULL on locally generated mail. I'm not 859738032Speter sure this is necessary, but a lot of people have complained 859838032Speter about it, and there is a legitimate question as to whether 859938032Speter "localhost" is legal as an 822-style domain. 860038032Speter Fix a problem with very short line lengths (mailer L= flag) in 860138032Speter headers. This causes a leading space to be added onto 860238032Speter continuation lines (including in the body!), and also 860338032Speter tries to wrap headers containing addresses (From:, To:, 860438032Speter etc) intelligently at the shorter line lengths. Problem 860538032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 860638032Speter Log the real user name when logging syserrs, since these can have 860738032Speter security implications. Suggested by several people. 860838032Speter Fix address logging of cached connections -- it used to always 860938032Speter log the numeric address as zero. This is a somewhat 861038032Speter bogus implementation in that it does an extra system 861138032Speter call, but it should be an inexpensive one. Fix from 861238032Speter Motonori Nakamura. 861338032Speter Tighten up handling of short syslog buffers even more -- there 861438032Speter were cases where the outgoing relay= name was too long 861538032Speter to share a line with delay= and mailer= logging. 861638032Speter Limit the overhead on split envelopes to one open file descriptor 861738032Speter per envelope -- previously the overhead was three 861838032Speter descriptors. This was in response to a problem reported 861938032Speter by P{r (Pell) Emanuelsson. 862038032Speter Fixes to better handle the case of unexpected connection closes; 862138032Speter this redirects the output to the transcript so the info 862238032Speter is not lost. From Eric Wassenaar. 862338032Speter Fix potential string overrun if you macro evaluate a string that 862438032Speter has a naked $ at the end. Problem noted by James Matheson 862538032Speter <jmrm@eng.cam.ac.uk>. 862638032Speter Make default error number on $#error messages 553 (``Requested 862738032Speter action not taken: mailbox name not allowed'') instead of 862838032Speter 501 (``Syntax error in parameters or arguments'') to 862938032Speter avoid bogus "protocol error" messages. 863038032Speter Strip off any existing trailing dot on names during $[ ... $] 863138032Speter lookup. This prevents it from ending up with two dots 863238032Speter on the end of dot terminated names. From Wesley Craig 863338032Speter of the University of Michigan and Bryan Costales of ICSI. 863438032Speter Clean up file class reading so that the debugging information is 863538032Speter more informative. It hadn't been using setclass, so you 863638032Speter didn't see the class items being added. 863738032Speter Avoid core dump if you are running a version of sendmail where 863838032Speter NIS is compiled in, and you specify an NIS map, but 863938032Speter NIS is not running. Fix from John Oleynick of 864038032Speter Rutgers. 864138032Speter Diagnose bizarre case where res_search returns a failure value, 864238032Speter but sets h_errno to a success value. 864338032Speter Make sure that "too many hops" messages are considered important 864438032Speter enough to send an error to the Postmaster (that is, the 864538032Speter address specified in the P option). This fix should 864638032Speter help problems that cause the df file to be left around 864738032Speter sometimes -- unfortunately, I can't seem to reproduce 864838032Speter the problem myself. 864938032Speter Avoid core dump (null pointer reference) on EXPN command; this 865038032Speter only occurred if your log level was set to 10 or higher 865138032Speter and the target account was an alias or had a .forward file. 865238032Speter Problem noted by Janne Himanka. 865338032Speter Avoid "denial of service" attacks by someone who is flooding your 865438032Speter SMTP port with bad commands by shutting the connection 865538032Speter after 25 bad commands are issued. From Kyle Jones of 865638032Speter UUNET. 865738032Speter Fix core dump on error messages with very long "to" buffers; 865838032Speter fmtmsg overflows the message buffer. Fixed by trimming 865938032Speter the to address to 203 characters. Problem reported by 866038032Speter John Oleynick. 866138032Speter Fix configuration for HASFLOCK -- there were some spots where 866238032Speter a #ifndef was incorrectly #ifdef. Pointed out by 866338032Speter George Baltz of the University of Maryland. 866438032Speter Fix a typo in savemail() that could cause the error message To: 866538032Speter lists to be incorrect in some places. From Motonori 866638032Speter Nakamura. 866738032Speter Fix a glitch that can cause duplicate error messages on split 866838032Speter envelopes where an address on one of the lists has a 866938032Speter name server failure. Fix from Voradesh Yenbut of the 867038032Speter University of Washington. 867138032Speter Fix possible bogus pointer reference on ESMTP parameters that 867238032Speter don't have an ``=value'' part. 867338032Speter CNAME loops caused an error message to be generated, but also 867438032Speter re-queued the message. Changed to just re-queue the 867538032Speter message (it's really hard to just bounce it because 867638032Speter of the weird way the name server works in the presence 867738032Speter of CNAME loops). Problem noted by James M.R.Matheson 867838032Speter of Cambridge University. 867938032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 868038032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 868138032Speter user name. Suggested by Andreas Stolcke of ICSI. 868238032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 868338032Speter override it easily in the Makefile -- that is, you can 868438032Speter turn it off using -DNAMED_BIND=0. 868538032Speter If a gethostbyname(...) of an address with a trailing dot fails, 868638032Speter try it without the trailing dot. This is because if 868738032Speter you have a version of gethostbyname() that falls back 868838032Speter to NIS or the /etc/hosts file it will fail to find 868938032Speter perfectly reasonable names that just don't happen to 869038032Speter be dot terminated in the hosts file. You don't want to 869138032Speter strip the dot first though because we're trying to ensure 869238032Speter that country names that match one of your subdomains get 869338032Speter a chance. 869438032Speter PRALIASES: fix bogus output on non-null-terminated strings. 869538032Speter From Bill Gianopoulos of Raytheon. 869638032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 869738032Speter This was in code intended to only catch the self-literal 869838032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 869938032Speter IP address), but the code was broken. However, it will 870038032Speter still do this if $M is defined; this is necessary to 870138032Speter get client configurations to work (sigh). Note that this 870238032Speter means that $M overrides :mailname entries in the user 870338032Speter database! Problem noted by Paul Southworth. 870438032Speter CONFIG: Fix definition of Solaris help file location. From 870538032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 870638032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 870738032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 870838032Speter and USENET_MAILER_MAX to tweak the maximum message 870938032Speter size for various mailers. 871038032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 871138032Speter instead of assuming that it is "inews" for consistency 871238032Speter with other mailers. From Michael Corrigan of UC San Diego. 871338032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 871438032Speter qualify the address in the SMTP envelope as user@{relay|hub} 871538032Speter instead of user@$j. From Bill Wisner of The Well. 871638032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 871738032Speter CONFIG: Don't turn off case mapping of user names in the local 871838032Speter mailer for IRIX. This was different than most every other 871938032Speter system. 872038032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 872138032Speter envelope. Noted by Thierry Besancon 872238032Speter <besancon@excalibur.ens.fr>. 872338032Speter CONFIG: Don't include -z by default on uux line -- most systems 872438032Speter don't want it set by default. Pointed out by Philippe 872538032Speter Michel of Thomson CSF. 872638032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 872738032Speter host name was foo.bar.ray.com and you matched against 872838032Speter ".ray.com", the old implementation bound %1 to "bar" 872938032Speter instead of "foo.bar". Also, allow "." in the mailertable 873038032Speter to match anything -- essentially, take over SMART_HOST. 873138032Speter This also moves matching of explicit local host names 873238032Speter before the mailertable so they don't have to be special 873338032Speter cased in the mailertable data. Reported by Bill 873438032Speter Gianopoulos of Raytheon; the fix for the %1 binding 873538032Speter problem was contributed by Nicholas Comanos of the 873638032Speter University of Sydney. 873738032Speter CONFIG: Don't include "root" in class $=L (users to deliver 873838032Speter locally, even if a hub or relay exists) by default. 873938032Speter This is because of the known bug where definition of 874038032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 874138032Speter both and deliver into the local mailbox. 874238032Speter CONFIG: Move up bitdomain and uudomain handling so that they 874338032Speter are done before .UUCP class matching; uudomain was 874438032Speter reported as ineffective before. This also frees up 874538032Speter diversion 8 for future use. Problem reported by Kimmo 874638032Speter Suominen. 874738032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 874838032Speter into host names. As pointed out by Jonathan Kamens, 874938032Speter these are often used because either the forward or reverse 875038032Speter mapping is broken; this translation makes it broken again. 875138032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 875238032Speter Suominen. 875338032Speter Portability fixes: 875438032Speter Unicos from David L. Kensiski of Sterling Software. 875538032Speter DomainOS from Don Lewis of Silicon Systems. 875638032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 875738032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 875838032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 875938032Speter BSD/386 from Tony Sanders of BSDI. 876038032Speter Apollo from Eric Wassenaar. 876138032Speter DGUX from Doug Anderson. 876238032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 876338032Speter NEW FILES: 876438032Speter src/Makefile.DomainOS 876538032Speter src/Makefile.PTX 876638032Speter src/Makefile.SunOS.5.1 876738032Speter src/Makefile.SunOS.5.2 876838032Speter src/Makefile.SunOS.5.x 876938032Speter src/mailq.1 877038032Speter cf/ostype/domainos.m4 877138032Speter doc/op/Makefile 877238032Speter doc/intro/Makefile 877338032Speter doc/usenix/Makefile 877438032Speter 877564562Sgshapiro8.6.5/8.6.5 1994/01/13 877638032Speter Security fix: /.forward could be owned by anyone (the test 877738032Speter to allow root to own any file was backwards). From 877838032Speter Bob Campbell at U.C. Berkeley. 877938032Speter Security fix: group ids were not completely set when programs 878038032Speter were invoked. This caused programs to have group 878138032Speter permissions they should not have had (usually group 878238032Speter daemon instead of their own group). In particular, 878338032Speter Perl scripts would refuse to run. 878438032Speter Security: check to make sure files that are written are not 878538032Speter symbolic links (at least under some circumstances). 878638032Speter Although this does not respond to a specific known 878738032Speter attack, it's just a good idea. Suggested by 878838032Speter Christian Wettergren. 878938032Speter Security fix: if a user had an NFS mounted home directory on 879038032Speter a system with a restricted shell listed in their 879138032Speter /etc/passwd entry, they could still execute any 879238032Speter program by putting that in their .forward file. 879338032Speter This fix prevents that by insisting that their shell 879438032Speter appear in /etc/shells before allowing a .forward to 879538032Speter execute a program or write a file. You can disable 879638032Speter this by putting "*" in /etc/shells. It also won't 879738032Speter permit world-writable :include: files to reference 879838032Speter programs or files (there's no way to disable this). 879943730Speter These behaviors are only one level deep -- for 880038032Speter example, it is legal for a world-writable :include: 880138032Speter file to reference an alias that writes a file, on 880238032Speter the assumption that the alias file is well controlled. 880338032Speter Security fix: root was not treated suspiciously enough when 880438032Speter looking into subdirectories. This would potentially 880538032Speter allow a cracker to examine files that were publicly 880638032Speter readable but in a non-publicly searchable directory. 880738032Speter Fix a problem that causes an error on QUIT on a cached 880838032Speter connection to create problems on the current job. 880938032Speter These are typically unrelated, so errors occur in 881038032Speter the wrong place. 881138032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 881238032Speter runs more responsive to load average, and fixes a 881338032Speter problem that ignored the load average in locally 881438032Speter generated mail. From Eric Wassenaar. 881538032Speter Fix possible core dump on aliases with null LHS. From 881638032Speter John Orthoefer of BB&N. 881738032Speter Revert to using flock() whenever possible -- there are just 881838032Speter too many bugs in fcntl() locking, particularly over 881938032Speter NFS, that cause sendmail to fail in perverse ways. 882038032Speter Fix a bug that causes the connection cache to get confused 882138032Speter when sending error messages. This resulted in 882238032Speter "unexpected close" messages. It should fix itself 882338032Speter on the following queue run. Problem noted by 882438032Speter Liudvikas Bukys of the University of Rochester. 882538032Speter Include $k in $=k as documented in the Install & Op Guide. 882638032Speter This seems odd, but it was documented.... From 882738032Speter Michael Corrigan of UCSD. 882838032Speter Fix problem that caused :include:s from alias files to be 882938032Speter forced to be owned by root instead of daemon 883038032Speter (actually DefUid). From Tim Irvin. 883138032Speter Diagnose unrecognized I option values -- from Mortin Forssen 883238032Speter of the Chalmers University of Technology. 883338032Speter Make "error" mailer work consistently when there is no error 883438032Speter code associated with it -- previously it returned OK 883538032Speter even though there was a real problem. Now it assumes 883638032Speter EX_UNAVAILABLE. 883738032Speter Fix bug that caused the last header line of messages that had 883838032Speter no body and which were terminated with EOF instead of 883938032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 884038032Speter Fix core dump on SMTP mail to programs that failed -- it tried 884138032Speter to go to a "next MX host" when none existed, causing 884238032Speter a core dump. From der Mouse at McGill University. 884338032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 884438032Speter this makes it easier to turn it off (using 884538032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 884638032Speter Fix YP_MASTER_NAME store to use the unupdated result of 884738032Speter gethostname() (instead of myhostname(), which tries 884838032Speter to fully qualify the name) to be consistent with 884938032Speter SunOS. If your hostname is unqualified, this fixes 885038032Speter transfers to slave servers. Bug noted by Keith 885138032Speter McMillan of Ameritech Services, Inc. 885238032Speter Fix Ultrix problem: gethostbyname() can return a very large 885338032Speter (> 500) h_length field, which causes the sockaddr 885438032Speter to be trashed. Use the size of the sockaddr instead. 885538032Speter Fix from Bob Manson of Ohio State. 885638032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 885738032Speter defined -- this confuses gethostbyname on hosts 885838032Speter file lookups, which doesn't understand the trailing 885938032Speter dot convention. 886038032Speter Log SMTP server subprocesses that die with a signal instead 886138032Speter of from a clean exit. 886238032Speter If you don't have option "I" set, don't assume that a DNS 886338032Speter "host unknown" message is authoritative -- it 886438032Speter might still be found in /etc/hosts. 886538032Speter Fix a problem that would cause Deferred: messages to be sent 886638032Speter as the subject of an error message, even though the 886738032Speter actual cause of a message was more severe than that. 886838032Speter Problem noted by Chris Seabrook of OSSI. 886938032Speter Fix race condition in DBM alias file locking. From Kyle 887038032Speter Jones of UUNET. 887138032Speter Limit delivery syslog line length to avoid bugs in some 887238032Speter versions of syslog(3). This adds a new compile time 887338032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 887438032Speter University, which is in turn derived from IDA. 887538032Speter Fix quotes inside of comments in addresses -- previously 887638032Speter it insisted that they be balanced, but the 822 spec 887738032Speter says that they should be ignored. 887838032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 887938032Speter debugging). This also evaluates ruleset 89, if set 888038032Speter (with the null input), and logs the result. This 888138032Speter should be used sparingly, since the rewrite process 888238032Speter is not reentrant. 888338032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 888438032Speter documented in the Bat Book. 888538032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 888638032Speter return an error message and did not requeue the message. 888738032Speter Fix based on code from Roland Dirlewanger of 888838032Speter Reseau Regional Aquarel, Bordeaux, France. 888938032Speter Fix a problem that caused a seg fault if you got a 421 error 889038032Speter code during some parts of connection initialization. 889138032Speter I've only seen this when talking to buggy mailers on 889238032Speter the other end, but it shouldn't give a seg fault in 889338032Speter any case. From Amir Plivatsky. 889438032Speter Fix core dump caused by a ruleset call that returns null. 889538032Speter Fix from Bryan Costales of ICSI. 889638032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 889738032Speter of Kyoto University. 889838032Speter Fix a possible problem with very long input lines in setproctitle. 889938032Speter From P{r Emanuelsson. 890038032Speter Avoid putting "This is a warning message" out on return receipts. 890138032Speter Suggested by Douglas Anderson. 890238032Speter Detect loops caused by recursive ruleset calls. Suggested by 890338032Speter Bryan Costales. 890438032Speter Initialize non-alias maps during alias rebuilds -- they may be 890538032Speter needed for parsing. Problem noted by Douglas Anderson. 890638032Speter Log sender address even if no message was collected in SMTP 890738032Speter (e.g., if all RCPTs failed). Suggested by Motonori 890838032Speter Nakamura. 890938032Speter Don't reflect the owner-list contents into the envelope sender 891038032Speter address if the value contains ", :, /, or | (to avoid 891138032Speter illegal addresses appearing there). 891238032Speter Efficiency hack for toktype macro -- from Craig Partridge of 891338032Speter BB&N. 891438032Speter Clean up DNS error printing so that a host name is always 891538032Speter included. 891638032Speter Remember to set $i during queue runs. Reported by Stephen 891738032Speter Campbell of Dartmouth University. 891838032Speter If the environment variable HOSTALIASES is set, use it during 891938032Speter canonification as the name of a file with per-user host 892038032Speter translations so that headers are properly mapped. Reported 892138032Speter by Anne Bennett of Concordia University. 892238032Speter Avoid printing misleading error message if SMTP mailer (not 892338032Speter using [IPC]) should die on a core dump. 892438032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 892538032Speter by the other end closing the connection. From 892638032Speter Dave Morrison of Oracle. 892738032Speter Improve several of the error messages printed by "mailq" 892838032Speter to include a host name or other useful information. 892938032Speter Add NetInfo preliminary support for NeXT systems. From Vince 893038032Speter DeMarco. 893138032Speter Fix a glitch that sometimes caused :include:s that pointed to 893238032Speter NFS filesystems that were down to give an "aliasing/ 893338032Speter forwarding loop broken" message instead of queueing 893438032Speter the message for retry. Noted by William C Fenner of 893538032Speter the NRL Connection Machine Facility. 893638032Speter Fix a problem that could cause a core dump if the input sequence 893738032Speter had (or somehow acquired) a \231 character. 893838032Speter Make sure that route-addrs always have <angle brackets> around 893938032Speter them in non-SMTP envelopes (SMTP envelopes already do 894038032Speter this properly). 894138032Speter Avoid weird headers on unbalanced punctuation of the form: 894238032Speter ``Joe User <user)'' -- this caused reference to the 894338032Speter null macro. Fix from Rick McCarty of IO.COM. 894438032Speter Fix a problem that caused an alias "user: user@local.host" to 894538032Speter not have the QNOTREMOTE bit set; this caused configs 894638032Speter to act as if FEATURE(notsticky) was defined even when 894738032Speter it was not. The effect of the problem was to make it 894838032Speter very hard to to set up satellite sites that had a few 894938032Speter local accounts, with everything else forwarded to a 895038032Speter corporate hub. Reported by Detlef Drewanz of the 895138032Speter University of Rostock and Mark Frost of NCD. 895238032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 895338032Speter addresses. This is more efficient (fewer name server 895438032Speter calls) and fixes certain unusual configurations, such 895538032Speter as those that have ruleset 4 do something that is 895638032Speter non-idempotent unless a mailer-specific ruleset did 895738032Speter something else. Problem reported by Brian J. Coan 895838032Speter of the Institute for Global Communications. 895938032Speter Fix the "obsolete argument" routine in main to better understand 896038032Speter new arguments. For example, if you used ``sendmail 896138032Speter -C config -v -q'' it would choke on the -q because 896238032Speter the -C would stop looking for old-format arguments. 896338032Speter Fix the code that was intended to allow two users to forward their 896438032Speter mail to the same program and have them appear unique. 896538032Speter Portability fixes for: 896638032Speter SCO UNIX from Murray Kucherawy. 896738032Speter SCO Open Server 3.2v4 from Philippe Brand. 896838032Speter System V Release 4 from Rick Ellis and others. 896938032Speter OSF/1 from Steve Campbell. 897038032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 897138032Speter of Stoner Associates. 897238032Speter Motorola SysV88 from Kevin Johnson of Motorola. 897338032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 898738032Speter of the config file has moved to /usr/lib 898838032Speter to match the HP-UX version of sendmail. 898938032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 899038032Speter since this is intended only for internal use, the 899138032Speter usual RFC 821/822/1123 rules can be relaxed. The 899238032Speter main point of this is to avoid munging (ugh) UUCP 899338032Speter addresses when relaying internally. 899438032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 899538032Speter syntax addresses delivered via UUCP. Solution 899638032Speter provided by Peter Wemm. 899738032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 899838032Speter zero; it caused double @ signs in addresses. From 899938032Speter Irving Reid of the University of Toronto. 900038032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 900138032Speter from Markku Toijala of ICL Personal Systems Oy. 900238032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 900338032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 900438032Speter that made it hard to recognize your own pseudodomain 900538032Speter names. 900638032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 900738032Speter rather than letting them get "local configuration 900838032Speter error"s. Problem noted by John Gardiner Myers. 900938032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 901038032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 901138032Speter has uucp-dom semantics but old UUCP syntax. This 901238032Speter also permits "uucp-old" as an alias for "uucp" and 901338032Speter "uucp-new" as a synonym for "suucp" for consistency. 901438032Speter CONFIG: add POP mailer support (from Kimmo Suominen 901538032Speter <kim@grendel.lut.fi>). 901638032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 901738032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 901838032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 901938032Speter was set; it would get an additional @masquerade.host 902038032Speter added to the address. Problem noted by Peter Wan 902138032Speter of Georgia Tech. 902238032Speter CONFIG: make sure that the local UUCP name is in $=w. From 902338032Speter Jim Murray of Stratus. 902438032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 902538032Speter mailer flag. Briefly, if you are sending to host 902638032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 902738032Speter "foo!baz" remains "foo!baz", and anything else has 902838032Speter the local name prepended. 902938032Speter CONFIG: portability fixes for HP-UX. 903038032Speter DOC: several minor problems fixed in the Install & Op Guide. 903138032Speter MAKEMAP: fix core dump problem on lines that are too long or 903238032Speter which lack newline.

This 906838032Speter makes quite certain that crackers can't use this 906938032Speter class of attack. 907038032Speter Reliability Fix: check return value from fclose() and fsync() 907138032Speter in a few critical places. 907238032Speter Minor problem in initsys() that reversed a condition for 907338032Speter redirecting the output channel on queue runs. It's 907438032Speter not clear this code even does anything. From Eric 907538032Speter Wassenaar of the Dutch National Institute for Nuclear 907638032Speter and High-Energy Physics. 907738032Speter Fix some problems that caused queue runs to do "too much work", 907838032Speter such as double-reading the Errors-To: header. From 907938032Speter Eric Wassenaar. 908038032Speter Error messages on writing the temporary file (including the 908138032Speter data file) were getting suppressed in SMTP -- this 908238032Speter fix causes them to be properly reported. From Eric 908338032Speter Wassenaar. 908438032Speter Some changes to support AF_UNIX sockets -- this will only 908538032Speter really become relevant in the next release, but some 908638032Speter people need it for local patches. From Michael 908738032Speter Corrigan of UC San Diego. 908838032Speter Use dynamically allocated memory (instead of static buffers) 908938032Speter for macros defined in initsys() and settime(); since 909038032Speter these can have different values depending on which 909138032Speter envelope they are in. From Eric Wassenaar. 909238032Speter Improve logging to show ctladdr on to= logging; this tells you 909338032Speter what uid/gid processes ran as. 909438032Speter Fix a problem that caused error messages to be discarded if 909538032Speter the sender address was unparseable for some reason; 909638032Speter this was supposed to fall back to the "return to 909738032Speter postmaster" case. 909838032Speter Improve aliaswait backoff algorithm. 909938032Speter Portability patches for Linux (8.6.3 required another header 910038032Speter file) (from Karl London) and SCO UNIX. 910138032Speter CONFIG: patch prog mailer to not strip host name off of envelope 910238032Speter addresses (so that it matches local again). From 910338032Speter Christopher Davis. 910438032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 910538032Speter this prevents uux from seeing lines with null names like 910638032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 910738032Speter Nakamura of Kyoto University. 910838032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 910938032Speter it shouldn't fail miserably.

From Eric 912838032Speter Wassenaar. 912938032Speter Fix some server SMTP synchronization problems caused when 913038032Speter connections fail during message collection. From 913138032Speter Eric Wassenaar. 913238032Speter Fix a problem that can cause srvrsmtp to reject mail if the 913338032Speter name server is down -- it accepts the RCPT but rejects 913438032Speter the DATA command. Problem reported by Jim Murray of 913538032Speter Stratus. 913638032Speter Fix a problem that can cause core dumps if the config file 913738032Speter incorrectly resolves to a null hostname.

Fix 914338032Speter from Sven-Ove Westberg of the University of Lulea. 914438032Speter Under very odd circumstances, the alias file rebuild code 914538032Speter could get confused as to whether a database was 914638032Speter open or not. 914738032Speter Check "vendor code" on the end of V lines -- this is 914838032Speter intended to provide a hook for vendor-specific 914938032Speter configuration syntax. (This is a "new feature", 915038032Speter but I've made an exception to my rule in a belief 915138032Speter that this is a highly exceptional case.) 915238032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 915338032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 915438032Speter (from Jon Forrest of UC Berkeley) 915538032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 915638032Speter 915764562Sgshapiro8.6.1/8.6 1993/10/08 915838032Speter Portability fixes for A/UX and Encore UMAX V. 915938032Speter Fix error message handling -- if you had a name server down 916038032Speter causing an error during parsing, that message was never 916138032Speter propagated to the queue file. 916238032Speter 916364562Sgshapiro8.6/8.6 1993/10/05 916438032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 916538032Speter conf.h (other systems have the same bug). 916638032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 916738032Speter getdtablesize() instead of sysconf(); a disturbingly 916838032Speter large number of systems defined _SC_OPEN_MAX in the 916938032Speter header files but don't have the syscall. 917038032Speter Another patch to really truly ignore MX records in getcanonname 917138032Speter if trymx == FALSE. 917238032Speter Fix problem that caused the "250 IAA25499 Message accepted for 917338032Speter delivery" message to be omitted if there was an error 917438032Speter in the header of the message (e.g., a bad Errors-To: 917538032Speter line). Pointed out by Michael Corrigan of UCSD. 917638032Speter Announce name of host we are chatting when we get errors; this 917738032Speter is an IDA-ism suggested by Christophe Wolfhugel. 917838032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 917938032Speter Australian Artificial Intelligence Institute), SCO Unix 918038032Speter (from Murray Kucherawy of Hookup Communication Corp.), 918138032Speter NeXT (from Vince DeMarco and myself), Linux (from 918238032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 918338032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 918438032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 918538032Speter Some changes to get around gcc optimizer bugs. From Takahiro 918638032Speter Kanbe. 918738032Speter Fix error recovery in queueup if another tf file of the same 918838032Speter name already exists. Problem stumbled over by Bill 918938032Speter Wisner of The Well. 919038032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 919138032Speter Problem noted by Keith McMillan of Ameritech Services. 919238032Speter Deal with group permissions properly when opening .forward and 919338032Speter :include: files. This relaxes the 8.1C restrictions 919438032Speter slightly more. This includes proper setting of groups 919538032Speter when reading :include: files, allowing you to read some 919638032Speter files that you should be able to read but have previously 919738032Speter been denied unless you owned them or they had "other" 919838032Speter read permission. 919938032Speter Make certain that $j is in $=w (after the .cf is read) so that 920038032Speter if the user is forced to override some silly system, 920138032Speter MX suppression will still work. 920238032Speter Fix a couple of efficiency problems where newstr was double- 920338032Speter calling expensive routines. In at least one case, it 920438032Speter wasn't guaranteed that they would always return the 920538032Speter same result. Problem noted by Christophe Wolfhugel. 920638032Speter Fix null pointer dereference in putoutmsg -- only on an error 920738032Speter condition from a non-SMTP mailer. From Motonori 920838032Speter Nakamura. 920938032Speter Macro expand "C" line class definitions before scanning so that 921038032Speter "CX $Z" works. 921138032Speter Fix problem that caused error message to be sent while still 921238032Speter trying to send the original message if the connection 921338032Speter is closed during a DATA command after getting an error 921438032Speter on an RCPT command (pretty obscure). Problem reported 921538032Speter by John Myers of CMU. 921638032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 921738032Speter term bug. 921838032Speter Fix a nasty bug causing core dumps when returning the "warning: 921938032Speter cannot deliver for N hours -- will keep trying" message; 922043730Speter it only occurred if you had PostmasterCopy set and 922138032Speter only on some architectures. Although sendmail would 922238032Speter keep trying, it would send error messages on each 922338032Speter queue interval. This is an important fix. 922438032Speter Allow u and g options to take user and group names respectively. 922538032Speter Don't do a chdir into the queue directory in -bt mode to make 922638032Speter ruleset testing a bit easier. 922738032Speter Don't allow users to turn off logging (using -oL) on the command 922838032Speter line -- command line can only raise, not lower, logging 922938032Speter level. 923038032Speter Set $u to the original recipient on the SMTP transaction or on 923138032Speter the command line. This is only done if there is exactly 923238032Speter one recipient. Technically, this does not meet the 923338032Speter specs, because it does not guarantee a domain on the 923438032Speter address. 923538032Speter Fix a problem that dumped error messages on bad addresses if 923638032Speter you used the -t flag. Problem noted by Josh Smith of 923738032Speter Harvey Mudd College. 923838032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 923938032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 924038032Speter avoid the problem of people who use angle brackets in 924138032Speter their full name information. 924238032Speter Fix a null pointer dereference if you set option "l", have 924338032Speter an Errors-To: header in the message, and have Errors-To: 924438032Speter defined in the config file H lines. From J.R. Oldroyd. 924538032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 924638032Speter wrong when compiling. Suggested by Rick McCarty of TI. 924738032Speter Fix a problem that could pass negative SIZE parameter if the 924838032Speter df file got lost; this would cause servers to always 924938032Speter give a temporary failure, making the problem even worse. 925038032Speter Problem noted by Allan Johannesen of WPI. 925138032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 925238032Speter protocol timeouts (30s default). Requested by Murray 925338032Speter Kucherawy of HookUp Communication Corp. to handle bogus 925438032Speter PC TCP/IP implementations. 925538032Speter Change $w default definition to be just the first component of 925638032Speter the domain name on config level 5. The $j macro defaults 925738032Speter to the FQDN; $m remains as before. This lets well-behaved 925838032Speter config files use any of the short, long, or subdomain 925938032Speter names. 926038032Speter Add makesendmail script in src to try to automate multi-architecture 926138032Speter builds. I know, this is sub-optimal, but it is still 926238032Speter helpful. 926338032Speter Fix very obscure race condition that can cause a queue run to 926438032Speter get a queue file for an already completed job. This 926538032Speter problem has existed for years. Problem noted by the 926638032Speter long suffering Allan Johannesen of WPI. 926738032Speter Fix a problem that caused the raw sender name to be passed to 926838032Speter udbsender instead of the canonified name -- this caused 926938032Speter it to sometimes miss records that it should have found. 927038032Speter Relax check of name on HELO packet so that a program using -bs 927138032Speter that claims to be itself works properly. 927238032Speter Restore rewriting of $: part of address through 2, R, 4 in 927338032Speter buildaddr -- this requires passing a lot of flags to get 927438032Speter it right. Unlike old versions, this ONLY rewrites 927538032Speter recipient addresses, not sender addresses. 927638032Speter Fix a bug that caused core dumps in config files that cannot 927738032Speter resolve /file/name style addresses. Fix from Jonathan 927838032Speter Kamens of OpenVision Technologies. 927938032Speter Fix problem with fcntl locking that can cause error returns to 928038032Speter be lost if the lock is lost; this required fully 928138032Speter queueing everything, dropping the envelope (so errors 928238032Speter would get returned), and then re-reading the queue from 928338032Speter scratch. 928438032Speter Fix a problem that caused aliases that redefine an otherwise 928538032Speter true address to still send to the original address 928638032Speter if and only if the alias failed in certain bizarre 928738032Speter ways (e.g, if they pointed at a list:; syntax address). 928838032Speter Problem pointed out by Jonathan Kamens. 928938032Speter Remove support for frozen configuration files. They caused 929038032Speter more trouble than it was worth. 929138032Speter Fix problem that can cause error messages to get ignored when 929238032Speter using both -odb and -t flags. Problem noted by Rob 929338032Speter McNicholas at U.C. Berkeley. 929438032Speter Include all "normal" variations on hostname in $=w. For example, 929538032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 929638032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 929738032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 929838032Speter the queue. 929938032Speter Reset SmtpPhase global on initial connection creation so that 930038032Speter messages don't come out with stale information. 930138032Speter Pass an "ext" argument to lockfile so that error/log messages 930238032Speter will properly reflect the true filename being locked. 930338032Speter Put all [...] address forms into $=w -- this eliminates the need 930438032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 930538032Speter Myers of CMU. 930638032Speter Fix a bug that can cause qf files to be left around even after 930738032Speter an SMTP RSET command. Problem and fix from Michael 930838032Speter Corrigan. 930943730Speter Don't send a PostmasterCopy to errors when the Precedence: is 931038032Speter negative. Error reports still go to the envelope 931138032Speter sender address. 931238032Speter Add LA_SHORT for load averages. 931338032Speter Lock sendmail.st file when posting statistics. 931438032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 931538032Speter set the size of the TCP send and receive buffers; if you 931638032Speter run over a slow slip line you may need to set these down 931738032Speter (although it would be better to fix the SLIP implementation 931838032Speter so that it's not necessary to recompile every program 931938032Speter that does bulk data transfer). 932038032Speter Allow null defaults on $( ... $) lookups. Problem reported by 932138032Speter Amir Plivatsky. 932238032Speter Diagnose crufty S and V config lines. This resulted from an 932338032Speter observation that some people were using the SITE macro 932438032Speter without the SITECONFIG macro first, which was causing 932538032Speter bogus config files that were not caught. 932638032Speter Fix makemap -f flag to turn off case folding (it was turning it 932738032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 932838032Speter Fix a problem that caused multiple error messages to be sent if 932938032Speter you used "sendmail -t -oem -odb", your system uses fcntl 933038032Speter locking, and one of the recipient addresses is unknown. 933138032Speter Reset uid earlier in include() so that recursive .forwards or 933238032Speter :include:s don't use the wrong uid. 933338032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 933438032Speter called, the code to recover the descriptor was broken. 933538032Speter This sometimes (only sometimes) caused problems with the 933638032Speter alias file. Fix from Motonori Nakamura. 933738032Speter Fix a problem that caused aliaswait to go into infinite recursion 933838032Speter if the @:@ metasymbol wasn't found in the alias file. 933938032Speter Improve error message on newaliases if database files cannot be 934038032Speter opened or if running with no database format defined. 934138032Speter Do a better estimation of the size of error messages when NoReturn 934238032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 934338032Speter Fix a problem causing the "c" option (don't connect to expensive 934438032Speter mailers) to be ignored in SMTP. Problem noted and the 934538032Speter solution suggested by Robert Elz of The University of 934638032Speter Melbourne. 934738032Speter Improve connection caching algorithm by passing "[host]" to 934838032Speter hostsignature, which strips the square brackets and 934938032Speter returns the real name. This allows mailertable entries 935038032Speter to match regular entries. 935138032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 935238032Speter feature, even if it doesn't work right. 935338032Speter Catch and log attempts to try the "wiz" command in server SMTP. 935438032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 935538032Speter Be more generous at assigning $z to the home directory -- do this 935638032Speter for programs that are specified through a .forward file. 935738032Speter Fix from Andrew Chang of Sun Microsystems. 935838032Speter Always save a fatal error message in preference to a non-fatal 935938032Speter error message so that the "subject" line of return 936038032Speter messages is the best possible. 936138032Speter CONFIG: reduce the number of quotes needed to quote configuration 936238032Speter parameters with commas: two quotes should work now, e.g., 936338032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 936438032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 936538032Speter connections (domain-ized UUCP). 936638032Speter CONFIG: fix bug in default maps (-o must be before database file 936764562Sgshapiro name). Pointed out by Christophe Wolfhugel. 936838032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 936938032Speter DNS. This would presumably be used in UUCP islands. 937038032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 937138032Speter CONFIG: log $u in Received: line. This is in technical violation 937238032Speter of the standards, since it doesn't guarantee a domain 937338032Speter on the address. 937438032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 937538032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 937638032Speter the "m" flag should you want it. Apparently some Solaris 2.2 937738032Speter installations can't handle multiple local recipients. 937838032Speter Problem noted by Josh Smith. 937938032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 938038032Speter CONFIG: change default version level from 4 to 5. 938138032Speter CONFIG: add FEATURE(nullclient) to create a config file that 938238032Speter forwards all mail to a hub without ever looking at the 938338032Speter addresses in any detail. 938438032Speter CONFIG: properly strip mailer: information off of relays when 938538032Speter used to change .BITNET form into %-hack form. 938638032Speter CONFIG: fix a problem that caused infinite loops if presented 938738032Speter with an address such as "!foo". 938838032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 938938032Speter the reverse "PTR" mapping is broken. There's a better 939038032Speter way to do this, but the change is fairly major and I 939138032Speter want to hold it for another release. Problem noted by 939238032Speter Bret Marquis. 939338032Speter 939464562Sgshapiro8.5/8.5 1993/07/23 939538032Speter Serious bug: if you used a command line recipient that was unknown 939638032Speter sendmail would not send a return message (it was treating 939738032Speter everything as though it had an SMTP-style client that 939838032Speter would do the return itself). Problem noted by Josh Smith. 939938032Speter Change "trymx" option in getcanonname() to ignore all MX data, 940038032Speter even during a T_ANY query. This actually didn't break 940138032Speter anything, because the only time you called getcanonname 940238032Speter with !trymx was if you already knew there were no MX 940338032Speter records, but it is somewhat cleaner. From Motonori 940438032Speter Nakamura. 940538032Speter Don't call getcanonname from getmxrr if you already know there 940638032Speter are no DNS records matching the name. 940738032Speter Fix a problem causing error messages to always include "The 940838032Speter original message was received ... from localhost". 940938032Speter The correct original host information is now included. 941038032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 941138032Speter version of "test" doesn't have the -x flag). Change it 941238032Speter to use -f instead. From John Myers. 941338032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 941438032Speter esmtp -- it should be smtp. 941538032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 941638032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 941738032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 941838032Speter this cleans up the configs somewhat. This fixes a serious 941938032Speter problem that caused route-addrs to get mistaken as relays, 942038032Speter pointed out by John Myers. WARNING: this also causes 942138032Speter the default on SMART_HOST to change from "suucp" to 942238032Speter "relay" if you have MAILER(smtp) specified. 942338032Speter 942464562Sgshapiro8.4/8.4 1993/07/22 942538032Speter Add option `w'. If you receive a message that comes to you because 942638032Speter you are the best (lowest preference) target of an MX, and 942738032Speter you haven't explicitly recognized the source MX host in 942838032Speter your .cf file, this option will cause you to try the target 942938032Speter host directly (as if there were no MX for it at all). If 943038032Speter `w' is not set, this case is a configuration error. 943138032Speter Beware: if `w' is set, senders may get bogus errors like 943238032Speter "message timed out" or "host unknown" for problems that 943338032Speter are really configuration errors. This option is 943438032Speter disrecommended, provided only for compatibility with 943538032Speter UIUC sendmail. 943638032Speter Fix a problem that caused the incoming socket to be left open 943738032Speter when sendmail forks after the DATA command. This caused 943838032Speter calling systems to wait in FIN_WAIT_2 state until the 943938032Speter entire list was processed and the child closed -- a 944038032Speter potentially prodigious amount of time. Problem noted 944138032Speter by Neil Rickert. 944238032Speter Fix problem (created in 6.64) that caused mail sent to multiple 944338032Speter addresses, one of which was a bad address, to completely 944438032Speter suppress the sending of the message. This changes 944538032Speter handling of EF_FATALERRS somewhat, and adds an 944638032Speter EF_GLOBALERRS flag. This also fixes a potential problem 944738032Speter with duplicate error messages if there is a syntax error 944838032Speter in the header of a message that isn't noticed until late 944938032Speter in processing. Original problem pointed out by Josh Smith 945038032Speter of Harvey Mudd College. This release includes quite a bit 945138032Speter of dickering with error handling (see below). 945238032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 945338032Speter will only hurt already-broken software and should help 945438032Speter humans. 945538032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 945638032Speter compiled in. It would never read the alias file. 945738032Speter Repair unbalanced `)' and `>' (the "open" versions are already 945838032Speter repaired). 945938032Speter Logging of "done" in dropenvelope() was incorrect: it would 946038032Speter log this even when the queue file still existed. Change 946138032Speter this to only log "done" (at log level 11) when the 946238032Speter queue file is actually removed. From John Myers. 946338032Speter Log "lost connection" in server SMTP at log level 20 if there 946438032Speter is no pending transaction. Some senders just close the 946538032Speter connection rather than sending QUIT. 946638032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 946738032Speter domains that do not have MX records -- this would cause 946838032Speter the subsequent host name lookup to fail. The problem 946938032Speter only occurred if you had FEATURE(nocanonify) set. 947038032Speter Problem noted by Rick McCarty of Texas Instruments. 947138032Speter Fix invocation of setvbuf when passed a -X flag -- I had 947238032Speter unwittingly used an ANSI C extension, and this caused 947338032Speter core dumps on some machines. 947438032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 947538032Speter Previously it just gave an empty send queue, which 947638032Speter then gave either "Need RCPT (recipient)" at the DATA 947738032Speter (confusing, since you had given an RCPT command which 947838032Speter returned 250) or just dropped the email, depending on 947938032Speter whether you were running VERBose mode. Now it usually 948038032Speter diagnoses this case as "aliasing/forwarding loop broken". 948138032Speter Unfortunately, it still doesn't adequately diagnose 948238032Speter some true error conditions. 948338032Speter Add internal concept of "warning messages" using 6xx codes. 948438032Speter These are not reported only to Postmaster. Unbalanced 948538032Speter parens, brackets, and quotes are printed as 653 codes. 948638032Speter They are always mapped to 5xx codes before use in SMTP. 948738032Speter Clean up error messages to tell both the actual address that 948838032Speter failed and the alias they arose from. This makes it 948938032Speter somewhat easier to diagnose problems. Difficulty noted 949038032Speter by Motonori Nakamura. 949138032Speter Fix a problem that inappropriately added a ctladdr to addresses 949238032Speter that shouldn't have had one during a queue run. This 949338032Speter caused error messages to be handled differently during 949438032Speter a queue run than a direct run. 949538032Speter Don't print the qf name and line number if you get errors during 949638032Speter the direct run of the queue from srvrsmtp -- this was 949738032Speter just extra stuff for users to crawl through. 949838032Speter Put command line flags on second line of pid file so you can 949938032Speter auto-restart the daemon with all appropriate arguments. 950038032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 950138032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 950238032Speter restart it. 950338032Speter Remove the ``setuid(getuid())'' in main -- this caused the 950438032Speter IDENT daemon to screw up. This required that I change 950538032Speter HASSETEUID to HASSETREUID and complicate the mode 950638032Speter changing somewhat because both Ultrix and SunOS seem 950738032Speter to have a bug causing seteuid() to set the saved uid 950838032Speter as well as the effective. The program test/t_setreuid.c 950938032Speter will test to see if your implementation of setreuid(2) 951038032Speter is appropriately functional. 951138032Speter The FallBackMX (option V) handling failed to properly identify 951238032Speter fallback to yourself -- most of the code was there, 951338032Speter but it wasn't being enabled. Problem noted by Murray 951438032Speter Kucherawy of the University of Waterloo. 951538032Speter Change :include: open timeout from ETIMEDOUT to an internal 951638032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 951738032Speter with CurHostName" in error messages, which can be 951838032Speter confusing. Reported by Jonathan Kamens of OpenVision 951938032Speter Technologies. 952038032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 952138032Speter process group id. The original fix was to get around 952238032Speter some problems with recalcitrant MUAs, but it breaks 952338032Speter any call from a shell that creates a process group id 952438032Speter different from the process id. I could try to fix 952538032Speter this by diddling the tty owner (using tcsetpgrp or 952638032Speter equivalent) but this is too likely to break other 952738032Speter things. 952838032Speter Portability changes: 952938032Speter Support -M as equivalent to -oM on Ultrix -- apparently 953038032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 953138032Speter instead of using standard flags. Oh joy. This 953243730Speter behavior reported by Jon Giltner of University 953338032Speter of Colorado. 953438032Speter SGI IRIX -- this includes several changes that should 953538032Speter help other strict ANSI compilers. 953638032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 953738032Speter Corporation. 953838032Speter Solaris running the Sun C compiler (which despite the 953938032Speter documentation apparently doesn't define 954038032Speter __STDC__ by default). 954138032Speter ConvexOS from Eric Schnoebelen of Convex. 954238032Speter Sony NEWS workstations and Omron LUNA workstations from 954338032Speter Motonori Nakamura. 954438032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 954538032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 954638032Speter several people have made a good argument that this 954738032Speter creates more problems than it solves (although this 954838032Speter may prove painful in the short run). 954938032Speter CONFIG: generalize all the relays to accept a "mailer:host" 955038032Speter format. 955138032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 955238032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 955338032Speter addresses are also passed through this ruleset. 955438032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 955538032Speter internet-style addresses would "fall off the end" of 955638032Speter ruleset zero and be interpreted as local -- however, 955738032Speter the angle brackets confused the recursive call. 955838032Speter These are now diagnosed as "Unrecognized host name". 955938032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 956038032Speter ifdef(`_MAILER_USENET_') instead of 956138032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 956238032Speter of SINTEF RUNIT, Oslo. 956338032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 956438032Speter early in ruleset 0; this allows .mc authors to bypass 956538032Speter things like the "short circuit" code for local addresses. 956638032Speter Prompted by a comment by Bill Wisner of The Well. 956738032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 956838032Speter esmtp) to send SMTP mail. This allows you to default 956938032Speter to esmtp but use a mailertable or other override to 957038032Speter deal with broken servers. This logic was pointed out 957138032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 957238032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 957338032Speter environments. Ugly as sin. 957438032Speter 957564562Sgshapiro8.3/8.3 1993/07/13 957638032Speter Fix setuid problems introduced in 8.2 that caused messages 957738032Speter like "Cannot create qfXXXXXX: Invalid argument" 957838032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 957938032Speter involved a new compile flag "HASSETEUID" that takes 958038032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 958138032Speter that the POSIX interface is broken enough to break 958238032Speter some systems badly. This includes some fixes for 958338032Speter HP-UX. Also fixes problems where the real uid is 958438032Speter not reset properly on startup (from Neil Rickert). 958538032Speter Fix a problem that caused timed out messages to not report the 958638032Speter addresses that timed out. Error messages are also more 958738032Speter "user friendly". 958838032Speter Drop required bandwidth on connections from 64 bytes/sec to 958938032Speter 16 bytes/sec. 959038032Speter Further Solaris portability changes -- doesn't require the BSD 959138032Speter compatibility library. This also adds a new 959238032Speter "HASGETDTABLESIZE" compile flag which can be used if 959338032Speter you want to use getdtablesize(2) instead of sysconf(2). 959438032Speter These are loosely based on changes from David Meyer at 959538032Speter University of Oregon. This now seems to work, at least 959638032Speter for quick test cases. 959738032Speter Fix a problem that can cause duplicate error messages to be 959838032Speter sent if you are in SMTP, you send to multiple addresses, 959938032Speter and at least one of those addresses is good and points 960038032Speter to an account that has a .forward file (whew!). 960138032Speter Fix a problem causing messages to be discarded if checkcompat() 960238032Speter returned EX_TEMPFAIL (because it didn't properly mark 960338032Speter the "to" address). Problem noted by John Myers. 960438032Speter Fix dfopen to return NULL if the open failed; I was depending 960538032Speter on fdopen(-1) returning NULL, which isn't the case. This 960638032Speter isn't serious, but does result in weird error diagnoses. 960738032Speter From Michael Corrigan. 960838032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 960938032Speter messages sent through UUCP-family mailers. Suggested 961038032Speter by Bill Wisner of The Well. 961138032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 961238032Speter include a "uucp-dom" mailer that uses domain-style 961338032Speter addressing. Suggested by Bill Wisner. 961438032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 961538032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 961638032Speter Christophe Wolfhugel. 961738032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 961838032Speter 961964562Sgshapiro8.2/8.2 1993/07/11 962038032Speter Don't drop out on config file parse errors in -bt mode. 962138032Speter On older configuration files, assume option "l" (use Errors-To 962238032Speter header) for back compatibility. NOTE: this DOES NOT 962338032Speter imply an endorsement of the Errors-To: header in any way. 962438032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 962538032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 962638032Speter SMTP server to give an error on this command, and 962738032Speter logging it in the transcript can be confusing. Fix 962838032Speter from Bill Wisner. 962938032Speter IRIX compatibility changes provided by Dan Rich 963038032Speter <drich@sandman.lerc.nasa.gov>. 963138032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 963238032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 963338032Speter <juo@klinzhai.rutgers.edu> 963438032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 963538032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 963638032Speter match the other flags in that file. 963738032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 963838032Speter Save h_errno in mci struct and improve error message display. 963938032Speter Changes from Eric Wassenaar. 964038032Speter Open /dev/null for the transcript if the create of the xf file 964138032Speter failed; this avoids at least one possible null pointer 964238032Speter reference in very weird cases. From Eric Wassenaar. 964338032Speter Clean up statistics gathering; it was over-reporting because of 964438032Speter forks. From Eric Wassenaar. 964538032Speter Fix problem that causes old Return-Path: line to override new 964638032Speter Return-Path: line (conf.c needs H_FORCE to avoid 964738032Speter re-using old value). From Motonori Nakamura. 964838032Speter Fix broken -m flag in K definition -- even if -m (match only) 964938032Speter was specified, it would still replace the key with the 965038032Speter value. Noted by Rick McCarty of Texas Instruments. 965138032Speter If the name server timed out over several days, no "timed out" 965238032Speter message would ever be sent back. The timeout code 965338032Speter has been moved from markfailure() to dropenvelope() 965438032Speter so that all such failures should be diagnosed. Pointed 965538032Speter out by Christophe Wolfhugel and others. 965638032Speter Relax safefile() constraints: directories in an include or 965738032Speter forward path must be readable by self if the controlling 965838032Speter user owns the entry, readable by all otherwise (e.g., 965938032Speter when reading your .forward file, you have to own and 966038032Speter have X permission in it; everyone needs X permission in 966138032Speter the root and directories leading up to your home); 966238032Speter include files must be readable by anyone, but need not 966338032Speter be owned by you. 966438032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 966538032Speter reading a .forward file; this gets around some problems 966638032Speter on NFS mounts if root permission is not exported and 966738032Speter the user's home directory isn't x'able. 966838032Speter Additional NeXT portability enhancements from Axel Zinser. 966938032Speter Additional HP-UX portability enhancements from Brian Bullen. 967038032Speter Add a timeout around SMTP message writes; this assumes you can 967138032Speter get throughput of at least 64 bytes/second. Note that 967238032Speter this does not impact the "datafinal" default, which 967338032Speter is separate; this is just intended to work around 967438032Speter network clogs that will occur before the final dot 967538032Speter is sent. From Eric Wassenaar. 967638032Speter Change map code to set the "include null" flag adaptively -- 967738032Speter it initially tries both, but if it finds anything 967838032Speter matching without a null it never tries again with a 967938032Speter null and vice versa. If -N is specified, it never 968038032Speter tries without the null and creates new maps with a 968138032Speter null byte. If -O is specified, it never tries with 968238032Speter the null (for efficiency). If -N and -O are specified, 968338032Speter you get -NO (get it?) lookup at all, so this would 968438032Speter be a bad idea. If you don't specify either -N or -O, 968538032Speter it adapts. 968638032Speter Fix recognition of "same from address" so that MH submissions 968738032Speter will insert the appropriate full name information; 968838032Speter this used to work and got broken somewhere along the 968938032Speter way. 969038032Speter Some changes to eliminate some unnecessary SYSERRs in the 969138032Speter log. For example, if you lost a connection, don't 969238032Speter bother reporting that fact on the connection you lost. 969338032Speter Add some "extended debugging" flags to try to track down 969438032Speter why we get occasional problems with file descriptor 969538032Speter one being closed when execing a mailer; it seems to 969638032Speter only happen when there has been another error in the 969738032Speter same transaction. This requires XDEBUG, defined 969838032Speter by default in conf.h. 969938032Speter Add "-X filename" command line flag, which logs both sides of 970038032Speter all SMTP transactions. This is intended ONLY for 970138032Speter debugging bad implementations of other mailers; start 970238032Speter it up, send a message from a mailer that is failing, 970338032Speter and then kill it off and examine the indicated log. 970438032Speter This output is not intended to be particularly human 970538032Speter readable. This also adds the HASSETVBUF compile 970638032Speter flag, defaulted on if your compiler defines __STDC__. 970738032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 970838032Speter have a local net that should get direct connects, you 970938032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 971038032Speter See cf/README for an example. 971138032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 971238032Speter sites that don't use the -d flag. 971338032Speter CONFIG: hide recipient addresses as well as sender addresses 971438032Speter behind $M if FEATURE(allmasquerade) is specified; this 971538032Speter has been requested by several people, but can break 971638032Speter local aliases. For example, if you mail to "localalias" 971738032Speter this will be rewritten as "localalias@masqueradehost"; 971838032Speter although initial delivery will work, replies will be 971938032Speter broken. Use it sparingly. 972038032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 972138032Speter to qualified domains in headers. I believe this is 972238032Speter largely equivalent to the IDA feature of the same name. 972338032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 972438032Speter to override the "system name" as your UUCP name -- 972538032Speter in particular, to use domain-ized UUCP names. From 972638032Speter Bill Wisner of The Well. 972738032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 972838032Speter first. This is currently unused in the config files, 972938032Speter but could be used in a mailertable entry. 973038032Speter 973164562Sgshapiro8.1C/8.1B 1993/06/27 973238032Speter Serious security bug fix: it was possible to read any file on 973338032Speter the system, regardless of ownership and permissions. 973438032Speter If a subroutine returns a fully qualified address, return it 973538032Speter immediately instead of feeding it back into rewriting. 973638032Speter This fixes a problem with mailertable lookups. 973738032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 973838032Speter 973964562Sgshapiro8.1B/8.1A 1993/06/12 974038032Speter Serious bug fix: pattern matching backup algorithm stepped by 974138032Speter two tokens in classes instead of one. Found by Claus 974238032Speter Assmann at University of Kiel, Germany. 974338032Speter 974464562Sgshapiro8.1A/8.1A 1993/06/08 974538032Speter Another mailertable fix.... 974638032Speter 974764562Sgshapiro8.1/8.1 1993/06/07 974838032Speter 4.4BSD freeze.
