Problem noted by Allan E Johannesen of 1377349Sgshapiro Worcester Polytechnic Institute. 1477349Sgshapiro Prevent "token too long" message by shortening {currHeader} which 1577349Sgshapiro could be too long if the last copied character was a quote. 1677349Sgshapiro Problem detected by Jan Krueger of digitalanswers 1777349Sgshapiro communications consulting gmbh. 1877349Sgshapiro Additional IPv6 check for unspecified addresses. Patch from 1977349Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 2077349Sgshapiro Do not ignore the ClientPortOptions setting if DaemonPortOptions 2177349Sgshapiro Modifier=b (bind to same interface) is set and the 2277349Sgshapiro connection came in from the command line. 2377349Sgshapiro Do not bind to the loopback address if DaemonPortOptions 2477349Sgshapiro Modifier=b (bind to same interface) is set. Patch from 2577349Sgshapiro John Beck of Sun Microsystems. 2677349Sgshapiro Properly deal with open failures on non-optional maps used in 2777349Sgshapiro check_* rulesets by returning a temporary failure. 2877349Sgshapiro Buffered file I/O files were not being properly fsync'ed to disk 2977349Sgshapiro when they were committed. 3077349Sgshapiro Properly encode '=' for the AUTH= parameter of the MAIL command. 3177349Sgshapiro Problem noted by Hadmut Danisch. 3277349Sgshapiro Under certain circumstances the macro {server_name} could be set 3377349Sgshapiro to the wrong hostname (of a previous connection), which may 3477349Sgshapiro cause some rulesets to return wrong results. This would 3577349Sgshapiro usually cause mail to be queued up and delivered later on. 3677349Sgshapiro Ignore F=z (LMTP) mailer flag if $u is given in the mailer A= 3777349Sgshapiro equate. Problem noted by Motonori Nakamura of Kyoto 3877349Sgshapiro University. 3977349Sgshapiro Work around broken accept() implementations which only partially 4077349Sgshapiro fill in the peer address if the socket is closed before 4177349Sgshapiro accept() completes. 4277349Sgshapiro Return an SMTP "421" temporary failure if the data file can't be 4377349Sgshapiro opened where the "354" reply would normally be given. 4477349Sgshapiro Prevent a CPU loop in trying to expand a macro which doesn't exist 4577349Sgshapiro in a queue run. Problem noted by Gordon Lack of Glaxo 4677349Sgshapiro Wellcome. 4777349Sgshapiro If delivering via a program and that program exits with EX_TEMPFAIL, 4877349Sgshapiro note that fact for the mailq display instead of just showing 4977349Sgshapiro "Deferred". Problem noted by Motonori Nakamura of Kyoto 5077349Sgshapiro University. 5177349Sgshapiro If doing canonification via /etc/hosts, try both the fully 5277349Sgshapiro qualified hostname as well as the first portion of the 5377349Sgshapiro hostname. Problem noted by David Bremner of the 5477349Sgshapiro University of New Brunswick. 5577349Sgshapiro Portability: 5677349Sgshapiro Fix a compilation problem for mail.local and rmail if SFIO 5777349Sgshapiro is in use. Problem noted by Auteria Wally 5877349Sgshapiro Winzer Jr. of Champion Nutrition. 5977349Sgshapiro IPv6 changes for platforms using KAME. Patch from 6077349Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 6177349Sgshapiro OpenBSD 2.7 and higher has srandomdev(3). OpenBSD 2.8 and 6277349Sgshapiro higher has BSDI-style login classes. Patch from 6377349Sgshapiro Todd C. Miller of Courtesan Consulting. 6477349Sgshapiro Unixware 7.1.1 doesn't allow h_errno to be set directly if 6577349Sgshapiro sendmail is being compiled with -kthread. Problem 6677349Sgshapiro noted by Orion Poplawski of CQG, Inc. 6777349Sgshapiro CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and 6877349Sgshapiro current left hand side for $LHS in virtuser files. 6977349Sgshapiro DEVTOOLS: Do not pass make targets to recursive Build invocations. 7077349Sgshapiro Problem noted by Jeff Bronson of J.D. Bronson, Inc. 7177349Sgshapiro MAIL.LOCAL: In LMTP mode, do not return errors regarding problems 7277349Sgshapiro storing the temporary message file until after the remote 7373188Sgshapiro side has sent the final DATA termination dot. Problem 7473188Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic 7573188Sgshapiro Institute. 7673188Sgshapiro MAIL.LOCAL: If LMTP mode is set, give a temporary error if users 7773188Sgshapiro are also specified on the command line. Patch from 7873188Sgshapiro Motonori Nakamura of Kyoto University. 7973188Sgshapiro PRALIASES: Skip over AliasFile specifications which aren't based on 8073188Sgshapiro database files (i.e., only show dbm, hash, and btree). 8173188Sgshapiro Renamed Files: 8273188Sgshapiro devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x 8373188Sgshapiro 8473188Sgshapiro8.11.2/8.11.2 2000/12/29 8573188Sgshapiro Prevent a segmentation fault when trying to set a class in 8673188Sgshapiro address test mode due to a negative array index. Audit 8773188Sgshapiro other array indexing. This bug is not believed to be 8873188Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 8973188Sgshapiro Schools" project (IdS). 9073188Sgshapiro Add an FFR (for future release) to drop privileges when using 9173188Sgshapiro address test mode. This will be turned on in 8.12. It can 9273188Sgshapiro be enabled by compiling with: 9373188Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 9473188Sgshapiro in your devtools/Site/site.config.m4 file. Suggested by 9573188Sgshapiro Michal Zalewski of the "Internet for Schools" project (IdS). 9673188Sgshapiro Fix potential problem with Cyrus-SASL security layer which may have 9773188Sgshapiro caused I/O errors, especially for mechanism DIGEST-MD5. 9873188Sgshapiro When QueueSortOrder was set to host, sendmail might not read 9973188Sgshapiro enough of the queue file to determine the host, making the 10073188Sgshapiro sort sub-optimal. Problem noted by Jeff Earickson of 10173188Sgshapiro Colby College. 10273188Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 10373188Sgshapiro RFC 1891) but don't have FAILURE as value. 10473188Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 10573188Sgshapiro This implies that every change to SASL related files requires 10673188Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 10773188Sgshapiro mechanisms (in form of shared libraries). 10873188Sgshapiro Properly set the STARTTLS related macros during a queue run for 10973188Sgshapiro a cached connection. Bug reported by Michael Kellen of 11073188Sgshapiro NxNetworks, Inc. 11173188Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 11273188Sgshapiro client name. 11373188Sgshapiro Include original length of bad field/header when reporting 11473188Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 11573188Sgshapiro the Universitat Regensburg. 11673188Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 11773188Sgshapiro DeliveryMode queue. Problem noted by Ric Anderson of the 11873188Sgshapiro University of Arizona. 11973188Sgshapiro Fix LDAP map -m (match only) flag. Problem noted by Jeff Giuliano 12073188Sgshapiro of Collective Technologies. 12173188Sgshapiro Avoid using a negative argument for sleep() calls when delaying answers 12273188Sgshapiro to EXPN/VRFY commands on systems which respond very slowly. 12373188Sgshapiro Problem noted by Mikolaj J. Habryn of Optus Internet 12473188Sgshapiro Engineering. 12573188Sgshapiro Make sure the F=u flag is set in the default prog mailer 12673188Sgshapiro definition. Problem noted by Kari Hurtta of the Finnish 12773188Sgshapiro Meteorological Institute. 12873188Sgshapiro Fix IPv6 check for unspecified addresses. Patch from 12973188Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 13073188Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 13173188Sgshapiro Meteorological Institute. 13273188Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 13373188Sgshapiro of the parameters to find Family= setting before trying to 13473188Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 13573188Sgshapiro Kletnieks of Virginia Tech. 13673188Sgshapiro When delivering to a file directly from an alias, do not call 13773188Sgshapiro initgroups(); instead use the DefaultUser group information. 13873188Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 13973188Sgshapiro RunAsUser now overrides the ownership of the control socket, if 14073188Sgshapiro created. Otherwise, sendmail can not remove it upon 14173188Sgshapiro close. Problem noted by Werner Wiethege. 14273188Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 14373188Sgshapiro overall connections, not the number of connections per 14473188Sgshapiro socket. A future version may change this to per socket 14573188Sgshapiro counting. 14673188Sgshapiro Portability: 14773188Sgshapiro Clean up libsmdb so it functions properly on platforms 14871345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t). Problem 14971345Sgshapiro noted by Rein Tollevik of Basefarm AS. 15071345Sgshapiro Fix man page formatting for compatibility with Solaris' 15171345Sgshapiro whatis.

Contributed by 16071345Sgshapiro Valdis Kletnieks of Virginia Tech. 16171345Sgshapiro Solaris 9 load average support from Andrew Tucker of Sun 16271345Sgshapiro Microsystems. 16371345Sgshapiro CONFIG: Reject addresses of the form a!b if FEATURE(`nouucp', `r') 16471345Sgshapiro is used. Problem noted by Phil Homewood of Asia Online, 16571345Sgshapiro patch from Neil Rickert of Northern Illinois University. 16671345Sgshapiro CONFIG: Change the default DNS based blacklist server for 16771345Sgshapiro FEATURE(`dnsbl') to blackholes.mail-abuse.org. 16871345Sgshapiro CONFIG: Deal correctly with the 'C' flag in {daemon_flags}, i.e., 16971345Sgshapiro implicitly assume canonical host names. 17071345Sgshapiro CONFIG: Deal with "::" in IPv6 addresses for access_db. Based on 17171345Sgshapiro patch by Motonori Nakamura of Kyoto University. 17271345Sgshapiro CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of 17371345Sgshapiro Virginia Tech. 17471345Sgshapiro CONFIG: Pass the illegal header form <list:;> through untouched 17571345Sgshapiro instead of making it worse.

Problem noted 17971345Sgshapiro by Jan Krueger of digitalanswers communications consulting 18071345Sgshapiro gmbh. 18171345Sgshapiro CONTRIB: domainmap.m4: Handle domains with '-' in them. From Mark 18271345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 18371345Sgshapiro DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4 18471345Sgshapiro variables into bldOS, bldREL, and bldARCH to prevent 18571345Sgshapiro namespace collisions. Problem noted by Motonori Nakamura 18671345Sgshapiro of Kyoto University. 18771345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 18871345Sgshapiro causes some changes in behavior and may break rmail for 18971345Sgshapiro installations where sendmail is actually a wrapper to 19071345Sgshapiro another MTA. The change will re-appear in a future 19171345Sgshapiro version. 19271345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 19371345Sgshapiro and SunOS 5.8. Requested by Jeff A. Earickson of Colby 19471345Sgshapiro College and John Beck of Sun Microsystems. 19571345Sgshapiro VACATION: Fix pattern matching for addresses to ignore. 19671345Sgshapiro VACATION: Don't reply to addresses of the form owner-* 19771345Sgshapiro or *-owner. 19871345Sgshapiro New Files: 19971345Sgshapiro cf/ostype/aix5.m4 20071345Sgshapiro contrib/buildvirtuser 20171345Sgshapiro devtools/OS/AIX.5.0 20271345Sgshapiro 20371345Sgshapiro8.11.1/8.11.1 2000/09/27 20471345Sgshapiro Fix SMTP EXPN command output if the address expands to a single 20571345Sgshapiro name. Fix from John Beck of Sun Microsystems. 20671345Sgshapiro Don't try STARTTLS in the client if the PRNG has not been properly 20771345Sgshapiro seeded. This problem only occurs on systems without 20871345Sgshapiro /dev/urandom. Problem detected by Jan Krueger of 20971345Sgshapiro digitalanswers communications consulting gmbh and 21071345Sgshapiro Neil Rickert of Northern Illinois University. 21171345Sgshapiro Don't use the . and .. directories when expanding QueueDirectory 21271345Sgshapiro wildcards. 21371345Sgshapiro Do not try to cache LDAP connections across processes as a parent 21471345Sgshapiro process may close the connection before the child process 21571345Sgshapiro has completed. Problem noted by Lai Yiu Fai of the Hong 21671345Sgshapiro Kong University of Science and Technology and Wolfgang 21771345Sgshapiro Hottgenroth of UUNET. 21871345Sgshapiro Use Timeout.fileopen to limit the amount of time spent trying to 21971345Sgshapiro read the LDAP secret from a file. 22071345Sgshapiro Prevent SIGTERM from removing a command line submitted item after 22171345Sgshapiro the user submits the message and before the first delivery 22271345Sgshapiro attempt completes. Problem noted by Max France of AlphaNet. 22371345Sgshapiro Fix from Neil Rickert of Northern Illinois University. 22471345Sgshapiro Deal correctly with MaxMessageSize restriction if message size is 22571345Sgshapiro greater than 2^31. Problem noted by Tim "Darth Dice" Bosserman 22671345Sgshapiro of EarthLink. 22771345Sgshapiro Turn off queue checkpointing if CheckpointInterval is set to zero. 22871345Sgshapiro Treat an empty home directory (from getpw*() or $HOME) as 22971345Sgshapiro non-existent instead of treating it as /. Problem noted by 23071345Sgshapiro Todd C. Miller of Courtesan Consulting. 23173188Sgshapiro Don't drop duplicate headers when reading a queued item. Problem 23271345Sgshapiro noted by Motonori Nakamura of Kyoto University. 23371345Sgshapiro Avoid bogus error text when logging the savemail panic "cannot 23471345Sgshapiro save rejected email anywhere". Problem noted by Marc G. 23571345Sgshapiro Fournier of Acadia University. 23671345Sgshapiro If an LDAP search fails because the LDAP server went down, close 23771345Sgshapiro the map so subsequent searches reopen the map. If there are 23871345Sgshapiro multiple LDAP servers, the down server will be skipped and 23971345Sgshapiro one of the others may be able to take over. 24071345Sgshapiro Set the ${load_avg} macro to the current load average, not the 24171345Sgshapiro previous load average query result. 24271345Sgshapiro If a non-optional map used in a check_* ruleset can't be opened, 24371345Sgshapiro return a temporary failure to the remote SMTP client 24471345Sgshapiro instead of ignoring the map. Problem noted by Allan E 24571345Sgshapiro Johannesen of Worcester Polytechnic Institute. 24671345Sgshapiro Avoid a race condition when queuing up split envelopes by saving 24771345Sgshapiro the split envelopes before the original envelope. 24871345Sgshapiro Fix a bug in the PH_MAP code which caused mail to bounce instead of 24973188Sgshapiro defer if the PH server could not be contacted. From Mark 25071345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 25171345Sgshapiro Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and 25271345Sgshapiro ETRN. Problem noted by Erik R. Leo of SoVerNet. 25371345Sgshapiro Change error code for unrecognized parameters to the SMTP MAIL and 25471345Sgshapiro RCPT commands from 501 to 555 per RFC 1869.

Suggested by 26571345Sgshapiro Henrik Nordstrom of Ericsson. 26671345Sgshapiro On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of 26766494Sgshapiro /usr/lib/sendmail for rmail and vacation. From 26866494Sgshapiro Jeff A. Earickson of Colby College. 26966494Sgshapiro On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which 27066494Sgshapiro does not exist). From Jeff A. Earickson of Colby 27166494Sgshapiro College. 27266494Sgshapiro Avoid using the UCB subsystem on NCR MP-RAS 3.x. From 27366494Sgshapiro Tom Moore of NCR. 27466494Sgshapiro NeXT 3.X and 4.X installs man pages in /usr/man. From 27566494Sgshapiro Hisanori Gogota of NTT/InterCommunicationCenter. 27666494Sgshapiro Solaris 8 and later include /var/run. The default PID file 27766494Sgshapiro location is now /var/run/sendmail.pid. From John 27866494Sgshapiro Beck of Sun Microsystems. 27966494Sgshapiro SFIO includes snprintf() for those operating systems 28066494Sgshapiro which do not. From Todd C. Miller of Courtesan 28166494Sgshapiro Consulting. 28266494Sgshapiro CONFIG: Use the result of _CERT_REGEX_SUBJECT_ not {cert_subject}. 28366494Sgshapiro Problem noted by Kaspar Brand of futureLab AG. 28466494Sgshapiro CONFIG: Change 553 SMTP reply code to 501 to avoid problems with 28566494Sgshapiro errors in the MAIL address. 28666494Sgshapiro CONFIG: Fix FEATURE(nouucp) usage in example .mc files.

This more closely 29266494Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 29366494Sgshapiro Ericsson. 29466494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 29566494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 29666494Sgshapiro mailer as described in cf/README. 29766494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 29866494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 29966494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 30066494Sgshapiro makemap to 'unmake' the map. 30166494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 30266494Sgshapiro sendmail. 30366494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 30466494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 30566494Sgshapiro Meteorological Institute. 30666494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 30766494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 30866494Sgshapiro dot as the only character on the line. 30966494Sgshapiro New Files: 31066494Sgshapiro cf/ostype/solaris8.m4 31166494Sgshapiro 31266494Sgshapiro8.11.0/8.11.0 2000/07/19 31366494Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 31466494Sgshapiro (not the normal case), some operating systems will still 31566494Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 31666494Sgshapiro to drop all of its privileges. If sendmail needs to drop 31766494Sgshapiro these privileges and the operating system doesn't set the 31866494Sgshapiro saved-uid as well, exit with an error. Problem noted by 31966494Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 32066494Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 32166494Sgshapiro it populates. It is possible that some broken 32266494Sgshapiro implementations of snprintf() exist that do not do this. 32366494Sgshapiro Systems in this category should compile with 32466494Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 32566494Sgshapiro system and report broken implementations to 32666494Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 32766494Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 32866494Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 32966494Sgshapiro Implementation influenced by the example programs of 33066494Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 33166494Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 33266494Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 33366494Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 33466494Sgshapiro cf/README and doc/op/op.*. 33566494Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 33666494Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 33766494Sgshapiro ${server_name}, and ${server_addr}. These are documented 33866494Sgshapiro in cf/README and doc/op/op.*. 33966494Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 34066494Sgshapiro random data. 34166494Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 34266494Sgshapiro don't properly seed the PRNG for OpenSSL but want to 34366494Sgshapiro try to use STARTTLS despite the security problems. 34466494Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 34566494Sgshapiro support encryption. Based on code contributed by Tim 34666494Sgshapiro Martin of CMU. 34766494Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 34866494Sgshapiro strength factor. 34966494Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 35066494Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 35166494Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 35266494Sgshapiro of CMU. 35366494Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 35466494Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 35566494Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 35666494Sgshapiro Fix the default family selection for DaemonPortOptions. As 35766494Sgshapiro documented, unless a family is specified in a 35866494Sgshapiro DaemonPortOptions option, "inet" is the default. It is 35966494Sgshapiro also the default if no DaemonPortOptions value is set. 36066494Sgshapiro Therefore, IPv6 users should configure additional sockets 36166494Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 36266494Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 36366494Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 36466494Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 36566494Sgshapiro the interface information for an outgoing connection. 36666494Sgshapiro Not doing so was creating a mismatch between the socket 36766494Sgshapiro family and address used in subsequent connections if the 36866494Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 36966494Sgshapiro by John Beck of Sun Microsystems. 37066494Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 37166494Sgshapiro family based on the IP address. ${if_family} is no longer 37266494Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 37366494Sgshapiro of Sun Microsystems. 37466494Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 37566494Sgshapiro macros for both the incoming interface address/family and 37664562Sgshapiro the outgoing interface address/family. In order for M=b 37764562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 37864562Sgshapiro the incoming information in the queue file for later 37964562Sgshapiro delivery attempts. 38064562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 38164562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 38264562Sgshapiro smoe.org. 38364562Sgshapiro Add more vigilance in checking for putc() errors on output streams 38464562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 38564562Sgshapiro noted by Graeme Hewson of Oracle. 38664562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 38764562Sgshapiro Problem noted by Ajay Matia. 38864562Sgshapiro Under certain circumstances, an address could be listed as deferred 38964562Sgshapiro but would be bounced back to the sender as failed to be 39064562Sgshapiro delivered when it really should have been queued. Problem 39164562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 39264562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 39364562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 39464562Sgshapiro Hedeland of Ericsson. 39564562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 39664562Sgshapiro is defined to avoid a core dump due to incompatibilities 39764562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 39864562Sgshapiro of Northern Illinois University. 39964562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 40064562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 40164562Sgshapiro Convert the free disk space shown in a control socket status query 40264562Sgshapiro to kilobyte units. 40364562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 40464562Sgshapiro looking up the hostname, requeue the message for a later 40564562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 40664562Sgshapiro Polytechnic. 40764562Sgshapiro Under the proper circumstances, failed connections would be recorded 40864562Sgshapiro as "Bad file number" instead of "Connection failed" in the 40964562Sgshapiro queue file and persistent host status. Problem noted by 41064562Sgshapiro Graeme Hewson of Oracle. 41164562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 41264562Sgshapiro within the hoststatus directory (e.g., lost+found). 41364562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 41464562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 41564562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 41664562Sgshapiro If a message data file can't be opened at delivery time, panic and 41764562Sgshapiro abort the attempt instead of delivering a message that 41864562Sgshapiro states "<<< No Message Collected >>>". 41964562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 42064562Sgshapiro restrictive. Problem noted by Mark G. Thomas of Mark 42164562Sgshapiro G. Thomas Consulting. 42264562Sgshapiro Preserve source port number instead of replacing it with the ident 42364562Sgshapiro port number (113). 42464562Sgshapiro Document the queue status characters in the mailq man page. 42564562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 42664562Sgshapiro Process queued items in which none of the recipient addresses have 42764562Sgshapiro host portions (or there are no recipients). Problem noted 42864562Sgshapiro by Valdis Kletnieks of Virginia Tech. 42964562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 43064562Sgshapiro only the first to open the connection is allowed to close 43164562Sgshapiro it so a later map close doesn't break the connection for 43264562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 43364562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 43464562Sgshapiro authentication. Patch from Rainer Schoepf of the 43564562Sgshapiro University of Mainz. 43664562Sgshapiro Provide workaround for inconsistent handling of data passed 43764562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 43864562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

Suggested by 64664562Sgshapiro Martin Mokrejs of The Charles University and Neil Rickert of 64764562Sgshapiro Northern Illinois University. 64864562Sgshapiro PRALIASES: Restore 8.9.X functionality of being able to search for 64964562Sgshapiro particular keys in a database by specifying the keys on the 65064562Sgshapiro command line. Man page updated accordingly. Patch from 65164562Sgshapiro John Beck of Sun Microsystems. 65264562Sgshapiro VACATION: SunOS 4.X portability from Charles Levert of Ecole 65364562Sgshapiro Polytechnique de Montreal. 65464562Sgshapiro VACATION: Fix -t option which is ignored but available for 65564562Sgshapiro compatibility with Sun's version, based on patch from 65664562Sgshapiro Volker Dobler of Infratest Burke. 65764562Sgshapiro Added Files: 65864562Sgshapiro devtools/M4/UNIX/smlib.m4 65964562Sgshapiro devtools/OS/OSF1.V5.0 66064562Sgshapiro Deleted Files: 66164562Sgshapiro contrib/converting.sun.configs 66264562Sgshapiro Deleted Directories (already done in 8.10.0 but not listed): 66364562Sgshapiro doc/intro 66464562Sgshapiro doc/usenix 66564562Sgshapiro doc/changes 66664562Sgshapiro 66764562Sgshapiro8.10.0/8.10.0 2000/03/01 66864562Sgshapiro ************************************************************* 66964562Sgshapiro * The engineering department at Sendmail, Inc. has suffered * 67064562Sgshapiro * the tragic loss of a key member of our engineering team. * 67164562Sgshapiro * Julie Van Bourg was the Vice President of Engineering * 67264562Sgshapiro * at Sendmail, Inc. during the development and deployment * 67364562Sgshapiro * of this release.

Problem noted by Michal Zalewski of the 68864562Sgshapiro "Internet for Schools" project (IdS). 68964562Sgshapiro SECURITY: There is a potential for a denial of service attack if 69064562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 69164562Sgshapiro sendmail process while it is rebuilding the aliases file 69264562Sgshapiro (leaving it in an inconsistent state). This option and 69364562Sgshapiro its use is deprecated and will be removed from a future 69464562Sgshapiro version of sendmail. 69564562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 69664562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 69764562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 69864562Sgshapiro (IdS). 69964562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 70064562Sgshapiro a large number of files. See cf/README for more details. 70164562Sgshapiro The directory structure of the distribution has changed slightly 70264562Sgshapiro for easier code sharing among the programs. 70364562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 70464562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 70564562Sgshapiro which hold the client's authentication credentials, 70664562Sgshapiro the mechanism used for authentication, and the 70764562Sgshapiro authorization identity (i.e., the AUTH= parameter if 70864562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 70964562Sgshapiro On systems which use the Torek stdio library (all of the BSD 71064562Sgshapiro distributions), use memory-buffered files to reduce 71164562Sgshapiro file system overhead by not creating temporary files on 71264562Sgshapiro disk. Contributed by Exactis.com, Inc. 71364562Sgshapiro New option DataFileBufferSize to control the maximum size of a 71464562Sgshapiro memory-buffered data (df) file before a disk-based file is 71564562Sgshapiro used. Contributed by Exactis.com, Inc. 71664562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 71764562Sgshapiro memory-buffered transcript (xf) file before a disk-based 71864562Sgshapiro file is used. Contributed by Exactis.com, Inc. 71964562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 72064562Sgshapiro now listen on several different ports. Use: 72164562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 72264562Sgshapiro to run a Message Submission Agent (MSA); this is turned 72364562Sgshapiro on by default in m4-generated .cf files; it can be turned 72464562Sgshapiro off with FEATURE(`no_default_msa'). 72564562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 72664562Sgshapiro begin using RFC 2476 Message Submission for initial user 72764562Sgshapiro message submission. XUSR may disappear from a future release. 72864562Sgshapiro The new '-G' (relay (gateway) submission) command line option 72964562Sgshapiro indicates that the message being submitted from the command 73064562Sgshapiro line is for relaying, not initial submission. This means 73164562Sgshapiro the message will be rejected if the addresses are not fully 73264562Sgshapiro qualified and no canonicalization will be done. Future 73364562Sgshapiro releases may even reject improperly formed messages. 73464562Sgshapiro The '-U' (initial user submission) command line option is 73564562Sgshapiro deprecated and may be removed from a future release. 73664562Sgshapiro Mail user agents should begin using '-G' to indicate that 73764562Sgshapiro this is a relay submission (the inverse of -U). 73864562Sgshapiro The next release of sendmail will assume that any message submitted 73964562Sgshapiro from the command line is an initial user submission and act 74064562Sgshapiro accordingly. 74164562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 74264562Sgshapiro program or deliver to file as the owner of that file, the 74364562Sgshapiro address is marked as unsafe. This means if RunAsUser is 74464562Sgshapiro set, users won't be able to use programs or delivery to 74564562Sgshapiro files in their .forward files. Administrators can override 74664562Sgshapiro this by setting the DontBlameSendmail option to the new 74764562Sgshapiro setting NonRootSafeAddr. 74864562Sgshapiro Allow group or world writable directories if the sticky bit is set 74964562Sgshapiro on the directory and DontBlameSendmail is set to 75064562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 75164562Sgshapiro InCert Software. 75264562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 75364562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 75464562Sgshapiro set in the DontBlameSendmail option. Requested by many. 75564562Sgshapiro New Timeout.control option to limit the total time spent satisfying 75664562Sgshapiro a control socket request. 75764562Sgshapiro New Timeout.resolver options for controlling BIND resolver 75864562Sgshapiro settings: 75964562Sgshapiro Timeout.resolver.retrans 76064562Sgshapiro Sets the resolver's retransmission time interval (in 76164562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 76264562Sgshapiro and Timeout.resolver.retrans.normal. 76364562Sgshapiro Timeout.resolver.retrans.first 76464562Sgshapiro Sets the resolver's retransmission time interval (in 76564562Sgshapiro seconds) for the first attempt to deliver a message. 76664562Sgshapiro Timeout.resolver.retrans.normal 76764562Sgshapiro Sets the resolver's retransmission time interval (in 76864562Sgshapiro seconds) for all resolver lookups except the first 76964562Sgshapiro delivery attempt. 77064562Sgshapiro Timeout.resolver.retry 77164562Sgshapiro Sets the number of times to retransmit a resolver 77264562Sgshapiro query. Sets both Timeout.resolver.retry.first 77364562Sgshapiro and Timeout.resolver.retry.normal. 77464562Sgshapiro Timeout.resolver.retry.first 77564562Sgshapiro Sets the number of times to retransmit a resolver 77664562Sgshapiro query for the first attempt to deliver a message. 77764562Sgshapiro Timeout.resolver.retry.normal 77864562Sgshapiro Sets the number of times to retransmit a resolver 77964562Sgshapiro query for all resolver lookups except the first 78064562Sgshapiro delivery attempt. 78164562Sgshapiro Contributed by Exactis.com, Inc. 78264562Sgshapiro Support multiple queue directories. To use multiple queues, supply 78364562Sgshapiro a QueueDirectory option value ending with an asterisk. For 78464562Sgshapiro example, /var/spool/mqueue/q* will use all of the 78564562Sgshapiro directories or symbolic links to directories beginning with 78664562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 78764562Sgshapiro mind, the queue directory structure should not be changed 78864562Sgshapiro while sendmail is running. Queue runs create a separate 78964562Sgshapiro process for running each queue unless the verbose flag is 79064562Sgshapiro given on a non-daemon queue run. New items are randomly 79164562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 79264562Sgshapiro Support different directories for qf, df, and xf queue files; if 79364562Sgshapiro subdirectories or symbolic links to directories of those names 79464562Sgshapiro exist in the queue directories, they are used for the 79564562Sgshapiro corresponding queue files. Keep in mind, the queue 79664562Sgshapiro directory structure should not be changed while sendmail is 79764562Sgshapiro running. Proposed by Mathias Koerber of Singapore 79864562Sgshapiro Telecommunications Ltd. 79964562Sgshapiro New queue file naming system which uses a filename guaranteed to be 80064562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 80164562Sgshapiro without fancy file system locking. Queued items can be 80264562Sgshapiro moved between queues easily. Contributed by Exactis.com, 80364562Sgshapiro Inc. 80464562Sgshapiro Messages which are undeliverable due to temporary address failures 80564562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 80664562Sgshapiro set. Contributed by Exactis.com, Inc. 80764562Sgshapiro New command line option '-L tag' which sets the identifier used for 80864562Sgshapiro syslog. Contributed by Exactis.com, Inc. 80964562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 81064562Sgshapiro avoids opening and reading each queue file when preparing 81164562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 81264562Sgshapiro Shared memory counters and microtimers functionality has been 81364562Sgshapiro donated by Exactis.com, Inc. 81464562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 81564562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 81664562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 81764562Sgshapiro being added. Suggested by Michael K. Sanders. 81864562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 81964562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 82064562Sgshapiro and John Beck of Sun Microsystems. 82164562Sgshapiro In low-disk space situations, where sendmail would previously refuse 82264562Sgshapiro connections, still accept them, but only allow ETRN commands. 82364562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 82464562Sgshapiro Ltd. 82564562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 82664562Sgshapiro on systems which support them. This can be used with LMTP 82764562Sgshapiro local delivery agents which listen on a named socket. An 82864562Sgshapiro example mailer might be: 82964562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 83064562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 83164562Sgshapiro A=FILE /var/run/lmtpd 83264562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 83364562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 83464562Sgshapiro instead. 83564562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 83664562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 83764562Sgshapiro connections), IPC (which will be deprecated in a future 83864562Sgshapiro version), and FILE (for UNIX domain socket delivery). 83964562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 84064562Sgshapiro flags. 84164562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 84264562Sgshapiro body of the original message on delivery status 84364562Sgshapiro notifications. 84464562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 84564562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 84664562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 84764562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 84864562Sgshapiro Steve Schweinhart of America Online. 84964562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 85064562Sgshapiro not be set after rulesets are defined. Suggested by 85164562Sgshapiro Mitchell Blank Jr of Exec-PC. 85264562Sgshapiro Do not report temporary failure on delivery to files. In 85364562Sgshapiro interactive delivery mode, this would result in two SMTP 85464562Sgshapiro responses after the DATA command. Problem noted by 85564562Sgshapiro Nik Conwell of Boston University. 85664562Sgshapiro Check file close when mailing to files. Problem noted by Nik 85764562Sgshapiro Conwell of Boston University. 85864562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 85964562Sgshapiro Curtis W. Hillegas of Princeton University. 86064562Sgshapiro Always bind to the LDAP server regardless of whether you are using 86164562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 86264562Sgshapiro @Home Network. 86364562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 86464562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 86564562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 86664562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 86764562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 86864562Sgshapiro similar to check_rcpt etc. 86964562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 87064562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 87164562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 87264562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 87364562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 87464562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 87564562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 87664562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 87764562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 87864562Sgshapiro the corresponding DSN parameter values. Proposed by 87964562Sgshapiro Mathias Herberts. 88064562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 88164562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 88264562Sgshapiro before the message has been collected, thereafter it holds 88364562Sgshapiro the message size as computed by sendmail (and can be used 88464562Sgshapiro in check_compat). 88564562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 88664562Sgshapiro sendmail is using instead of the value of the DeliveryMode 88764562Sgshapiro option. 88864562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 88964562Sgshapiro Drop explicit From: if same as what would be generated only if it is 89064562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 89164562Sgshapiro Write pid to file also if sendmail only processes the queue. 89264562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 89364562Sgshapiro Log "low on disk space" only when necessary. 89464562Sgshapiro New macro ${load_avg} can be used to check the current load average. 89564562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 89664562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 89764562Sgshapiro is set. 89864562Sgshapiro Flag -S for maps to specify the character which is substituted 89964562Sgshapiro for spaces (instead of the default given by O BlankSub). 90064562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 90164562Sgshapiro This flag is set by default for the host map. Based on a 90264562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 90364562Sgshapiro Open maps only on demand, not at startup. 90464562Sgshapiro Log warning about unsupported IP address families. 90564562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 90664562Sgshapiro of the sum of all headers. This can be used to prevent 90764562Sgshapiro a denial-of-service attack. 90864562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 90964562Sgshapiro headers and parameters within those headers. This option 91064562Sgshapiro is intended to protect mail user agents from buffer 91164562Sgshapiro overflow attacks. 91264562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 91364562Sgshapiro alias recursion. 91464562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 91564562Sgshapiro Map type syslog to log the key via syslogd. 91664562Sgshapiro Entries in the alias file can be continued by putting a backslash 91764562Sgshapiro directly before the newline. 91864562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 91964562Sgshapiro dead.letter file, formerly hardcoded to 92064562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 92164562Sgshapiro default), sendmail will not attempt to save to a 92264562Sgshapiro system-wide dead.letter file if it can not bounce the mail 92364562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 92464562Sgshapiro file as it has in the past when the dead.letter file 92564562Sgshapiro could not be opened. 92664562Sgshapiro New option PidFile to define the location of the pid file. The 92764562Sgshapiro value of this option is macro expanded. 92864562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 92964562Sgshapiro process title shown in 'ps' listings. 93064562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 93164562Sgshapiro (along with the already existing macros): 93264562Sgshapiro ${daemon_info} Daemon information, e.g. 93364562Sgshapiro SMTP+queueing@00:30:00 93464562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 93564562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 93664562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 93764562Sgshapiro ${daemon_port} Daemon port, e.g., 25 93864562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 93964562Sgshapiro New macros especially for virtual hosting: 94064562Sgshapiro ${if_name} hostname of interface of incoming connection. 94164562Sgshapiro ${if_addr} address of interface of incoming connection. 94264562Sgshapiro The latter is only set if the interface does not belong to the 94364562Sgshapiro loopback net. 94464562Sgshapiro If a message being accepted via a method other than SMTP and 94564562Sgshapiro would be rejected by a header check, do not send the message. 94664562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 94764562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 94864562Sgshapiro Provide header value as quoted string in the macro 94964562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 95064562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 95164562Sgshapiro The length of the header value is stored in ${hdrlen}. 95264562Sgshapiro H*: allows to specify a default ruleset for header checks. This 95364562Sgshapiro ruleset will only be called if the individual header does 95464562Sgshapiro not have its own ruleset assigned. Suggested by Jan 95564562Sgshapiro Krueger of Unix-AG of University of Hannover. 95664562Sgshapiro The name of the header field stored in ${hdr_name}. 95764562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 95864562Sgshapiro removed if the config file version is greater than or equal 95964562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 96064562Sgshapiro input "token (1)" but does not match "token". 96164562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 96264562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 96364562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 96464562Sgshapiro Ericsson. 96564562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 96664562Sgshapiro messages with 8-bit text in headers. Problem noted by 96764562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 96864562Sgshapiro of Ericsson. 96964562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 97064562Sgshapiro modified database map file. Problem noted by Chris Adams 97164562Sgshapiro of Renaissance Internet Services. 97264562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 97364562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 97464562Sgshapiro queue up the message instead of bouncing it. 97564562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 97664562Sgshapiro standard does not provide any indication of what to do when 97764562Sgshapiro something other than 250 is received. Based on a patch 97864562Sgshapiro from Steve Schweinhart of America Online. 97964562Sgshapiro New option TrustedUser allows to specify a user who can own 98064562Sgshapiro important files instead of root. This requires HASFCHOWN. 98164562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 98264562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 98364562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 98464562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 98564562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 98664562Sgshapiro $? tests also whether the macro is non-null. 98764562Sgshapiro Print an error message if a mailer definition contains an invalid 98864562Sgshapiro equate name. 98964562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 99064562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 99164562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 99264562Sgshapiro mailer to return after sending all data to it. 99364562Sgshapiro Only free memory from the process list when adding a new process 99464562Sgshapiro into a previously filled slot. Previously, the memory was 99564562Sgshapiro freed at removal time. Since removal can happen in a 99664562Sgshapiro signal handler, this may leave the memory map in an 99764562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 99864562Sgshapiro David Cooley of Colby College. 99964562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 100064562Sgshapiro local users in the passwd file. The UserDB code has 100164562Sgshapiro already decided the message will be passed to another host 100264562Sgshapiro for processing. Fix from Tony Landells of Burdett 100364562Sgshapiro Buckeridge Young Limited. 100464562Sgshapiro Support LDAP authorization via either a file containing the 100564562Sgshapiro password or Kerberos V4 using the new map options 100664562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 100764562Sgshapiro distinguished_name is who to login as. The method can be 100864562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 100964562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 101064562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 101164562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 101264562Sgshapiro of Stanford University. 101364562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 101464562Sgshapiro deprecated and will be removed in a future version. 101564562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 101664562Sgshapiro and the map has the column delimiter set, it turns that 101764562Sgshapiro response into a delimiter separated string. The LDAP map 101864562Sgshapiro will traverse multiple entries as well. LDAP alias maps 101964562Sgshapiro automatically set the column delimiter to the comma. 102064562Sgshapiro Based on patch from Booker Bense of Stanford University and 102164562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 102264562Sgshapiro Support return of multiple values for a single LDAP lookup. The 102364562Sgshapiro values to be returned should be in a comma separated string. 102464562Sgshapiro For example, `-v "email,emailother"'. Patch from 102564562Sgshapiro Curtis W. Hillegas of Princeton University. 102664562Sgshapiro Allow the use of LDAP for alias maps. 102764562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 102864562Sgshapiro attributes found in the match will be returned. 102964562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 103064562Sgshapiro breaking up a single entry into multiple entries. This is 103164562Sgshapiro needed for LDAP alias file specifications to allow for 103264562Sgshapiro comma separated key and value strings. 103364562Sgshapiro Keep connections to LDAP server open instead of opening and closing 103464562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 103564562Sgshapiro connections such that multiple maps which use the same 103664562Sgshapiro host, port, bind DN, and authentication will only result in 103764562Sgshapiro a single connection to that host. 103864562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 103964562Sgshapiro Be more careful about checking for errors and freeing memory on 104064562Sgshapiro LDAP lookups. 104164562Sgshapiro Use asynchronous LDAP searches to save memory and network 104264562Sgshapiro resources. 104364562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 104464562Sgshapiro Increase portability to the Netscape LDAP libraries. 104564562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 104664562Sgshapiro replaced with the literal contents of the map lookup key -- 104764562Sgshapiro note that this means a lookup can be done using the LDAP 104864562Sgshapiro special characters. The new '%0' token can be used instead 104964562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 105064562Sgshapiro For example, if the LDAP map specification contains '-k 105164562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 105264562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 105364562Sgshapiro user attribute. Instead, if the LDAP map specification 105464562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 105564562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 105664562Sgshapiro with the name "*". 105764562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 105864562Sgshapiro more than one is returned, it is equivalent to no records 105964562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 106064562Sgshapiro alias dereference option; "-Z size" limits the number of 106164562Sgshapiro matches to return. 106264562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 106364562Sgshapiro LDAP maps. The value should only contain LDAP specific 106464562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 106564562Sgshapiro settings will be used for all LDAP maps unless they are 106664562Sgshapiro specified in the individual map specification ('K' 106764562Sgshapiro command). This option should be set before any LDAP maps 106864562Sgshapiro are defined. 106964562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 107064562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 107164562Sgshapiro Tech. 107264562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 107364562Sgshapiro particular, class entries get much smaller, which can be 107464562Sgshapiro important if you have large classes. 107564562Sgshapiro On network-related temporary failures, record the hostname which 107664562Sgshapiro gave error in the queued status message. Requested by 107764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 107864562Sgshapiro Add new F=% mailer flag to allow for a store and forward 107964562Sgshapiro configuration. Mailers which have this flag will not attempt 108064562Sgshapiro delivery on initial receipt of a message or on queue runs 108164562Sgshapiro unless the queued message is selected using one of the 108264562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 108364562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 108464562Sgshapiro New option ControlSocketName which, when set, creates a daemon 108564562Sgshapiro control socket. This socket allows an external program to 108664562Sgshapiro control and query status from the running sendmail daemon 108764562Sgshapiro via a named socket, similar to the ctlinnd interface to the 108864562Sgshapiro INN news server. Access to this interface is controlled by 108964562Sgshapiro the UNIX file permissions on the named socket on most UNIX 109064562Sgshapiro systems (see sendmail/README for more information). An 109164562Sgshapiro example control program is provided as contrib/smcontrol.pl. 109264562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 109364562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 109464562Sgshapiro number of processors online on the system (if that can be 109564562Sgshapiro determined). For single processor machines, this change 109664562Sgshapiro has no effect. 109764562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 109864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 109964562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 110064562Sgshapiro Motonori Nakamura of Kyoto University. 110164562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 110264562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 110364562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 110464562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 110564562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 110664562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 110764562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 110864562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 110964562Sgshapiro connection-based denial of service attacks. 111064562Sgshapiro Log basic information about authenticated connections at LogLevel 111164562Sgshapiro 10 or higher. 111264562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 111364562Sgshapiro information (from= syslog line). 111464562Sgshapiro Log the DSN code for each recipient if one is available as a new 111564562Sgshapiro equate (dsn=). 111664562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 111764562Sgshapiro New "ph" map for performing ph queries in rulesets.

Contributed by Mark 112064562Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 112164562Sgshapiro Detect temporary lookup failures in the host map if looking up a 112264562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 112364562Sgshapiro Finnish Meteorological Institute. 112464562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 112564562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 112664562Sgshapiro When a forward file points to an alias which runs a program, run 112764562Sgshapiro the program as the default user and the default group, not 112864562Sgshapiro the forward file user. This change also assures the 112964562Sgshapiro :include: directives in aliases are also processed using 113064562Sgshapiro the default user and group. Problem noted by Sergiu 113164562Sgshapiro Popovici of DNT Romania. 113264562Sgshapiro Prevent attempts to save a dead.letter file for a user with 113364562Sgshapiro no home directory (/no/such/directory). Problem noted by 113464562Sgshapiro Michael Brown of Finnigan FT/MS. 113564562Sgshapiro Include message delay and number of tries when logging that a 113664562Sgshapiro message has been completely delivered (LogLevel of 10 or 113764562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 113864562Sgshapiro Log the sender of a message even if none of the recipients were 113964562Sgshapiro accepted. If some of the recipients were rejected, it is 114064562Sgshapiro helpful to know the sender of the message. 114164562Sgshapiro Check the root directory (/) when checking a path for safety. 114264562Sgshapiro Problem noted by John Beck of Sun Microsystems. 114364562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 114471345Sgshapiro interactive and delivering to an alias which resolves to 114564562Sgshapiro multiple files. 114664562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 114764562Sgshapiro greater (see below); the help function doesn't print the 114864562Sgshapiro version of sendmail any longer, instead it is placed in 114964562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 115064562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 115164562Sgshapiro skipped and a version line (#vers) is introduced. The 115264562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 115364562Sgshapiro version is found, a warning is logged. The '#vers' 115464562Sgshapiro directive should be placed at the top of the help file. 115564562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 115664562Sgshapiro disk succeeded. Suggested by Nick Christenson. 115764562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 115864562Sgshapiro length before the attempt. 115964562Sgshapiro If a forward points to a filename for delivery, change to the 116064562Sgshapiro user's uid before checking permissions on the file. This 116164562Sgshapiro allows delivery to files on NFS mounted directories where 116264562Sgshapiro root is remapped to nobody. Problem noted by Harald 116364562Sgshapiro Daeubler of Universitaet Ulm. 116464562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 116564562Sgshapiro host status files, not all files. 116664562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 116764562Sgshapiro in the queue file for the message and set when delivery 116864562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 116964562Sgshapiro Wonderworks Inc. 117064562Sgshapiro Add support for storing information between rulesets using the new 117164562Sgshapiro macro map class. This can be used to store information 117264562Sgshapiro between queue runs as well using $={persistentMacros}. 117364562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 117464562Sgshapiro of Hannover. 117564562Sgshapiro New map class arith to allow for computations in rules. The 117664562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 117764562Sgshapiro as key. The two operands are specified as arguments; the 117864562Sgshapiro lookup returns the result of the computation. For example, 117964562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 118064562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 118164562Sgshapiro Add new syntax for header declarations which decide whether to 118264562Sgshapiro include the header based on a macro rather than a mailer 118371345Sgshapiro flag: 118471345Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 118564562Sgshapiro This should be used along with $={persistentMacros}. 118664562Sgshapiro It can be used for adding headers to a message based on 118764562Sgshapiro the results of check_* and header check rulesets. 118864562Sgshapiro Allow new named config file rule check_eoh which is called after 118964562Sgshapiro all of the headers have been collected. The input to the 119064562Sgshapiro ruleset the number of headers and the size of all of the 119164562Sgshapiro headers in bytes separated by $|. This ruleset along with 119264562Sgshapiro the macro storage map can be used to correlate information 119364562Sgshapiro gathered between headers and to check for missing headers. 119464562Sgshapiro See cf/README or doc/op/op.ps for an example. 119564562Sgshapiro Change the default for the MeToo option to True to correspond 119664562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 119764562Sgshapiro option is deprecated and will be removed from a future 119864562Sgshapiro version. 119964562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 120064562Sgshapiro Change the sendmail binary default for SuperSafe to True. 120164562Sgshapiro Display ruleset names in debug and address test mode output 120264562Sgshapiro if referencing a named ruleset. 120364562Sgshapiro New mailer equate m= which will limit the number of messages 120464562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 120564562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 120664562Sgshapiro using it to sort. Now all the same domains are really run 120764562Sgshapiro through the queue together. If they have the same MX host, 120864562Sgshapiro then they will have a much better opportunity to use the 120964562Sgshapiro connection cache if available. This should be a reasonable 121064562Sgshapiro performance improvement. Patch from Randall Winchester of 121164562Sgshapiro the University of Maryland. 121264562Sgshapiro If a message is rejected by a header check ruleset, log who would 121364562Sgshapiro have received the message if it had not been rejected. 121464562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 121564562Sgshapiro queue immediately. No delivery attempt is made. 121664562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 121764562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 121864562Sgshapiro COMMANDS). 121964562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 122064562Sgshapiro but for outgoing connections. 122164562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 122264562Sgshapiro error messages and logging) and Modifiers, i.e. 122364562Sgshapiro a require authentication 122464562Sgshapiro b bind to interface through which mail has 122564562Sgshapiro been received 122664562Sgshapiro c perform hostname canonification 122764562Sgshapiro f require fully qualified hostname 122864562Sgshapiro h use name of interface for outgoing HELO 122964562Sgshapiro command 123064562Sgshapiro C don't perform hostname canonification 123164562Sgshapiro E disallow ETRN (see RFC 2476) 123264562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 123364562Sgshapiro h use name of interface for HELO command 123464562Sgshapiro The version number for queue files (qf) has been incremented to 4. 123564562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 123664562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 123764562Sgshapiro Institutes of Health. 123864562Sgshapiro If a mailer dies, print the status in decimal instead of octal 123964562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 124064562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 124164562Sgshapiro Move message priority from sender to recipient logging. Suggested by 124264562Sgshapiro Ulrich Windl of the Universitat Regensburg. 124364562Sgshapiro Add support for Berkeley DB 3.X. 124464562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 124564562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 124664562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 124764562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 124864562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 124964562Sgshapiro sub-options is set on the command line. Problem noted by 125064562Sgshapiro Graeme Hewson of Oracle. 125164562Sgshapiro Randomize equal preference MX records each time delivery is 125264562Sgshapiro attempted via a new connection to a host instead of once per 125364562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 125464562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 125564562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 125664562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 125764562Sgshapiro to hosts which have dynamically assigned names. 125864562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 125964562Sgshapiro the bounce for the same reason. If the body is not 8-bit 126064562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 126164562Sgshapiro not be included in the bounce. Problem noted by Valdis 126264562Sgshapiro Kletnieks of Virginia Tech. 126364562Sgshapiro The timeout for sending a message via SMTP has been changed from 126464562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 126564562Sgshapiro simply checks for progress on sending data every 5 minutes. 126664562Sgshapiro This will detect the inability to send information quicker 126764562Sgshapiro and reduce the number of processes simply waiting to 126864562Sgshapiro timeout. 126964562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 127064562Sgshapiro interface address structure when loading the system network 127164562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 127264562Sgshapiro Nanoteq. 127364562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 127464562Sgshapiro indicates the number of interfaces to read when probing 127564562Sgshapiro for hostnames and IP addresses for class w ($=w).

Proposed by Arne Wichmann 159164562Sgshapiro of MPI Saarbruecken, Griff Miller of PGS Tensor, 159264562Sgshapiro Jayme Cox of Broderbund Software Inc. 159364562Sgshapiro CONFIG: A list of exceptions for FEATURE(`nocanonify') can be 159464562Sgshapiro specified by CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE, 159564562Sgshapiro i.e., a list of domains which are passed to $[ ... $] 159664562Sgshapiro for canonification. Based on an idea from Neil Rickert 159764562Sgshapiro of Northern Illinois University. 159864562Sgshapiro CONFIG: If `canonify_hosts' is specified as parameter for 159964562Sgshapiro FEATURE(`nocanonify') then addresses which have only 160064562Sgshapiro a hostname, e.g., <user@host>, will be canonified. 160164562Sgshapiro CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is 160264562Sgshapiro nevertheless added to addresses with more than one component 160364562Sgshapiro in it. 160464562Sgshapiro CONFIG: Canonification is no longer attempted for any host or domain 160564562Sgshapiro in class 'P' ($=P). 160664562Sgshapiro CONFIG: New class for matching virtusertable entries $={VirtHost} that 160764562Sgshapiro can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE. 160864562Sgshapiro FEATURE(`virtuser_entire_domain') can be used to apply this 160964562Sgshapiro class also to entire subdomains. Hosts in this class are 161064562Sgshapiro treated as canonical in SCanonify2, i.e., a trailing dot 161164562Sgshapiro is added. 161264562Sgshapiro CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used, 161364562Sgshapiro include $={VirtHost} in $=R (hosts allowed to relay). 161464562Sgshapiro CONFIG: FEATURE(`generics_entire_domain') can be used to apply the 161564562Sgshapiro genericstable also to subdomains of $=G. 161664562Sgshapiro CONFIG: Pass "+detail" as %2 for virtusertable lookups. 161764562Sgshapiro Patch from Noam Freedman from University of Chicago. 161864562Sgshapiro CONFIG: Pass "+detail" as %1 for genericstable lookups. Suggested 161964562Sgshapiro by Raymond S Brand of rsbx.net. 162064562Sgshapiro CONFIG: Allow @domain in genericstable to override masquerading. 162164562Sgshapiro Suggested by Owen Duffy from Owen Duffy & Associates. 162264562Sgshapiro CONFIG: LOCAL_DOMAIN() adds entries to class w. Suggested by Steve 162364562Sgshapiro Hubert of University of Washington. 162464562Sgshapiro CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as 162564562Sgshapiro GNU is now the canonical system name. From Mark 162664562Sgshapiro Kettenis of the University of Amsterdam. 162764562Sgshapiro CONFIG: OSTYPE(`unixware7') updates from Larry Rosenman. 162864562Sgshapiro CONFIG: Do not include '=' in option expansion if there is no value 162964562Sgshapiro associated with the option. From Andrew Brown of 163064562Sgshapiro Graffiti World Wide, Inc. 163164562Sgshapiro CONFIG: Add MAILER(`qpage') to define a new pager mailer. Contributed 163264562Sgshapiro by Philip A. Prindeville of Enteka Enterprise Technology 163364562Sgshapiro Services. 163464562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 163564562Sgshapiro names. Problem noted by Randall Winchester of Swales 163664562Sgshapiro Aerospace. 163764562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 163864562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 163964562Sgshapiro University and Brian Candler. 164064562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 164164562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 164264562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 164364562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 164464562Sgshapiro Institute. 164564562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 164664562Sgshapiro i.e., to set, add, or delete flags. 164764562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 164864562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 164964562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 165064562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 165164562Sgshapiro after check_rcpt and allows for exceptions from the checks. 165264562Sgshapiro CONFIG: Map declarations have been moved into their associated 165364562Sgshapiro feature files to allow greater flexibility in use of 165464562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 165564562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 165664562Sgshapiro line string for the local mailer. Requested by Il Oh of 165764562Sgshapiro Willamette Industries, Inc. 165864562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 165964562Sgshapiro converted to <user@d> 166064562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 166164562Sgshapiro Sun's older, broken configuration files. 166264562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 166364562Sgshapiro normal configuration, allowing anti-spam checks to be 166464562Sgshapiro performed. 166564562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 166664562Sgshapiro ${client_name} can't be resolved just temporarily. 166764562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 166864562Sgshapiro Institute. 166964562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 167064562Sgshapiro be accessed by their numbers). 167164562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 167264562Sgshapiro which describes whether to disallow "!" in the local part 167364562Sgshapiro of an address. 167464562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 167564562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 167664562Sgshapiro set. If the ruleset returns a mailer, the appropriate 167764562Sgshapiro action is taken, otherwise the returned tokens are ignored. 167864562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 167964562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 168064562Sgshapiro The latter is kept around for backward compatibility. 168164562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 168264562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 168364562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 168464562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 168564562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 168664562Sgshapiro Institute. 168764562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 168864562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 168964562Sgshapiro arguments overriding the mailer program, arguments, and 169064562Sgshapiro mailer definition flags. This makes it possible to use 169164562Sgshapiro other programs such as maildrop for local delivery. 169264562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 169364562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 169464562Sgshapiro Patch from Richard A. Nelson of IBM. 169564562Sgshapiro CONFIG: Add SMTP Authentication information to Received: header 169664562Sgshapiro default value (confRECEIVED_HEADER). 169764562Sgshapiro CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a 169864562Sgshapiro local mailer. Problem noted by Per Hedeland of Ericsson. 169964562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 170064562Sgshapiro University of California at Berkeley. 170164562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of 170264562Sgshapiro Illinois at Urbana-Champaign. 170364562Sgshapiro CONTRIB: etrn.pl now recognizes bogus host names. Patch from 170464562Sgshapiro Bruce Barnett of GE's R&D Lab. 170564562Sgshapiro CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle 170664562Sgshapiro Corporation UK. 170764562Sgshapiro CONTRIB: Added qtool.pl to assist in managing the queues. 170864562Sgshapiro DEVTOOLS: Prevent user environment variables from interfering with 170964562Sgshapiro the Build scripts. Problem noted by Ezequiel H. Panepucci of 171064562Sgshapiro Yale University. 171164562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 171264562Sgshapiro be used for building. 171364562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 171464562Sgshapiro used for a fresh build. 171564562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 171664562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 171764562Sgshapiro ranlib. 171864562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 171964562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 172064562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 172164562Sgshapiro building of the man pages when defined. Suggested by Bryan 172264562Sgshapiro Costales. 172364562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 172464562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 172564562Sgshapiro installation of the sendmail helpfile and statistics file 172664562Sgshapiro respectively. Suggested by Bryan Costales. 172764562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 172864562Sgshapiro of Siemens Business Services. 172964562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 173064562Sgshapiro stdio library. The new buffered file I/O depends on the 173164562Sgshapiro Torek stdio library. This option can be either portable or 173264562Sgshapiro torek. 173364562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 173464562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 173564562Sgshapiro They should contain the C source files for the object files 173664562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 173764562Sgshapiro will be passed to the 'make depend' stage of compilation. 173864562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 173964562Sgshapiro in the sendmail distribution. Each has the form 174064562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 174164562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 174264562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 174364562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 174464562Sgshapiro building the distribution, but documentation on the changes 174564562Sgshapiro are in devtools/README. 174664562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 174764562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 174864562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 174964562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 175064562Sgshapiro new variable which identifies the root of the source 175164562Sgshapiro directories for all of the programs in the distribution. 175264562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 175364562Sgshapiro time. They can both still be overridden by setting the m4 175464562Sgshapiro macro. 175564562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 175664562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 175764562Sgshapiro build configurations, and places objects in obj.prefix.*/. 175864562Sgshapiro Complains as 'Build -f file' does for existing object 175964562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 176064562Sgshapiro Corporation. 176164562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 176264562Sgshapiro manual pages in the directory tree specified by 176364562Sgshapiro confMANROOTMAN. 176464562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 176564562Sgshapiro preformatted pages from the distribution. The new variable 176664562Sgshapiro confCOPY specifies the copying program. 176764562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 176864562Sgshapiro question. Suggested by Terry Lambert of Whistle 176964562Sgshapiro Communications. 177064562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 177164562Sgshapiro of the installed statistics and help files, respectively. 177264562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 177364562Sgshapiro operating system identity. Problem noted by Erik 177464562Sgshapiro Wachtenheim of Dartmouth College. 177564562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 177664562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 177764562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 177864562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 177964562Sgshapiro how to strip binaries. These are used by the new 178064562Sgshapiro install-strip target. 178164562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 178264562Sgshapiro the others (if it exists). 178364562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 178464562Sgshapiro then the default ones. 178564562Sgshapiro MAIL.LOCAL: Will not be installed setuid root. To use mail.local 178664562Sgshapiro as local delivery agent without LMTP mode, use 178764562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 178864562Sgshapiro to set the S flag. 178964562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 179064562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 179164562Sgshapiro Northern Illinois University. 179264562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 179364562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 179464562Sgshapiro the Finnish Meteorological Institute. 179564562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 179664562Sgshapiro MAILLOCK when compiling. Also requires linking with 179764562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 179864562Sgshapiro University. 179964562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 180064562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 180164562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 180264562Sgshapiro University. 180364562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 180464562Sgshapiro structure to the beginning of the program. This ensures that 180564562Sgshapiro the getservbyname() is done before any seteuid to a possibly 180664562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 180764562Sgshapiro on a Solaris system, this avoids syslog messages such as, 180864562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 180964562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 181064562Sgshapiro University. 181164562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 181264562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 181364562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 181464562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 181564562Sgshapiro characters (in LMTP mode), mail.local split the incoming 181664562Sgshapiro line up into 2046-character output lines (excluding the 181764562Sgshapiro newline). If an input line was 2047 characters long 181864562Sgshapiro (excluding CR-LF) and the last character was a '.', 181964562Sgshapiro mail.local saw it as the end of input, transfered it to the 182064562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 182164562Sgshapiro If the message was much longer, both sendmail and 182264562Sgshapiro mail.local would deadlock waiting for each other to read 182364562Sgshapiro what they have written. Problem noted by Peter Jeremy of 182464562Sgshapiro Alcatel Australia Limited. 182564562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 182664562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 182764562Sgshapiro Neil Rickert of Northern Illinois University. 182864562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 182964562Sgshapiro timeout to avoid starvation. 183064562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 183164562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 183264562Sgshapiro Infinite Monkeys & Co. 183364562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 183464562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 183564562Sgshapiro printed in a machine readable fashion and the stats file 183664562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 183764562Sgshapiro of Maryland. 183864562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 183964562Sgshapiro generated maps to the TrustedUser as specified in the 184064562Sgshapiro sendmail configuration file. 184164562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 184264562Sgshapiro configuration file to use for finding the TrustedUser 184364562Sgshapiro option. 184464562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 184564562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 184664562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 184764562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 184864562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 184964562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 185064562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 185164562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 185264562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 185364562Sgshapiro Corporation UK. 185464562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 185564562Sgshapiro (e.g., sendmail would not drop root privileges if the 185664562Sgshapiro option was specified on the command line). Problem noted 185764562Sgshapiro by Todd C. Miller of Courtesan Consulting. 185864562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 185964562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 186064562Sgshapiro Institute for Global Communications. 186164562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 186264562Sgshapiro alias file(s) if the -f option is not used. Patch from 186364562Sgshapiro John Beck of Sun Microsystems. 186464562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 186564562Sgshapiro configuration file to use for finding alias file(s). Patch 186664562Sgshapiro from John Beck of Sun Microsystems. 186764562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 186864562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 186964562Sgshapiro of the Institute for Global Communications. 187064562Sgshapiro SMRSH: Update README for the new Build system.

This change will match the wording to be 199964562Sgshapiro published in the updated SMTP specification from the DRUMS 200064562Sgshapiro group of the IETF. 200164562Sgshapiro Portability: 200264562Sgshapiro AIX 4.2.0 or 4.2.1 may become updated by the fileset 200364562Sgshapiro bos.rte.net level 4.2.0.2. This introduces the 200464562Sgshapiro softlink /usr/lib/libbind.a which should 200564562Sgshapiro not be used. It conflicts with the resolver 200664562Sgshapiro built into libc.a. "bind" has been removed 200764562Sgshapiro from the confLIBSEARCH BuildTools variable. 200864562Sgshapiro Users who have installed BIND 8.X will have 200964562Sgshapiro to add it back in their site.config.m4 file. 201064562Sgshapiro Problem noted by Ole Holm Nielsen of the 201164562Sgshapiro Technical University of Denmark. 201264562Sgshapiro CRAY TS 10.0.x from Sven Nielsen of San Diego 201364562Sgshapiro Supercomputer Center. 201464562Sgshapiro Improved LDAP version 3 integration based on input 201564562Sgshapiro from Kurt D.

Problem 208843730Speter noted by Josef Svitak of Montana State University. 208943730Speter Close all maps when exiting the process with one exception. 209043730Speter Berkeley DB can use internal shared memory locking for 209143730Speter its memory pool. Closing a map opened by another process 209243730Speter will interfere with the shared memory and locks of the 209343730Speter parent process leaving things in a bad state. For 209443730Speter Berkeley DB, only close the map if the current process 209543730Speter is also the one that opened the map, otherwise only close 209643730Speter the map file descriptor.

Sites 231538032Speter which need the ability to override security can use the 231638032Speter DontBlameSendmail option. See the README file for more 231743730Speter information. 231838032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 231938032Speter if maps or alias files are in world writable directories. 232038032Speter This fixes the change added to 8.8.6 to prevent links in these 232138032Speter world writable directories. 232238032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 232338032Speter it is in a world writable directory. 232438032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 232538032Speter tty it may be able to push bytes back to the senders input. 232638032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 233538032Speter reverts back to the old behavior of using uid 1 and gid 1. 233638032Speter This is a security problem for Linux which has chosen that 233738032Speter uid and gid for user bin instead of daemon. If DefaultUser 233838032Speter is set in the configuration file, that value overrides this 233938032Speter default. 234038032Speter SECURITY: Since 8.8.7, the check for non-setuid binaries 234138032Speter interfered with setting an alternate group id for the 234238032Speter RunAsUser option.

After this number is reached, sendmail 238638032Speter starts returning "452 Too many recipients" to all RCPT 238738032Speter commands. This can be used to limit the number of recipients 238838032Speter per envelope (in particular, to discourage use of the server 238938032Speter for spamming). Note: a better approach is to restrict 239038032Speter relaying entirely. 239138032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 239238032Speter to ldapx map and added timeout for ldap_open call to 239338032Speter avoid hanging sendmail in the event of hung LDAP servers. 239438032Speter Patch from Booker Bense of Stanford University. 239538032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 241438032Speter of Procter & Gamble. 241538032Speter The LDAP map -s flag was not properly parsed and the error message 241638032Speter given included the remainder of the arguments instead of 241738032Speter solely the argument in error. Problem noted by Aidan Nichol 241838032Speter of Procter & Gamble. 241938032Speter New DontBlameSendmail option. This option allows administrators to 242038032Speter bypass some of sendmail's file security checks at the expense 242138032Speter of system security. This should only be used if you are 242238032Speter absolutely sure you know the consequences. The available 242338032Speter DontBlameSendmail options are: 242438032Speter Safe 242538032Speter AssumeSafeChown 242638032Speter ClassFileInUnsafeDirPath 242738032Speter ErrorHeaderInUnsafeDirPath 242838032Speter GroupWritableDirPathSafe 242938032Speter GroupWritableForwardFileSafe 243038032Speter GroupWritableIncludeFileSafe 243138032Speter GroupWritableAliasFile 243264562Sgshapiro HelpFileinUnsafeDirPath 243338032Speter WorldWritableAliasFile 243438032Speter ForwardFileInGroupWritableDirPath 243538032Speter IncludeFileInGroupWritableDirPath 243638032Speter ForwardFileInUnsafeDirPath 243738032Speter IncludeFileInUnsafeDirPath 243838032Speter ForwardFileInUnsafeDirPathSafe 243938032Speter IncludeFileInUnsafeDirPathSafe 244038032Speter MapInUnsafeDirPath 244138032Speter LinkedAliasFileInWritableDir 244238032Speter LinkedClassFileInWritableDir 244338032Speter LinkedForwardFileInWritableDir 244438032Speter LinkedIncludeFileInWritableDir 244538032Speter LinkedMapInWritableDir 244638032Speter LinkedServiceSwitchFileInWritableDir 244738032Speter FileDeliveryToHardLink 244838032Speter FileDeliveryToSymLink 244938032Speter WriteMapToHardLink 245038032Speter WriteMapToSymLink 245138032Speter WriteStatsToHardLink 245238032Speter WriteStatsToSymLink 245338032Speter RunProgramInUnsafeDirPath 245438032Speter RunWritableProgram 245538032Speter New DontProbeInterfaces option to turn off the inclusion of all the 245638032Speter interface names in $=w on startup. In particular, if you 245738032Speter have lots of virtual interfaces, this option will speed up 245838032Speter startup. However, unless you make other arrangements, mail 245938032Speter sent to those addresses will be bounced. 246038032Speter Automatically create alias databases if they don't exist and 246138032Speter AutoRebuildAliases is set. 246238032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 246338032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 246438032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 246538032Speter When determining the client host name ($&{client_name} macro), do 246638032Speter a forward (A) DNS lookup on the result of the PTR lookup 246738032Speter and compare results. If they differ or if the PTR lookup 246838032Speter fails, &{client_name} will contain the IP address 246938032Speter surrounded by square brackets (e.g., [127.0.0.1]). 247038032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 247138032Speter (i.e, it is like -ax for the temporary failure case, in 247238032Speter contrast to the success case). 247338032Speter New syntax to do limited checking of header syntax. A config line 247438032Speter of the form: 247538032Speter HHeader: $>Ruleset 247664562Sgshapiro causes the indicated Ruleset to be invoked on the Header 247738032Speter when read. This ruleset works like the check_* rulesets -- 247838032Speter that is, it can reject mail on the basis of the contents. 247938032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 248064562Sgshapiro from hiding their connection information in Received: 248138032Speter headers. 248238032Speter When SingleThreadDelivery is active, deliveries to locked hosts 248338032Speter are skipped. This will cause the delivering process to 248438032Speter try the next MX host or queue the message if no other MX 248538032Speter hosts are available. Suggested by Alexander Litvin. 248638032Speter The [FILE] mailer type now delivers to the file specified in the 248738032Speter A= equate of the mailer definition instead of $u. It also 248838032Speter obeys all of the F= mailer flags such as the MIME 248938032Speter 7/8 bit conversion flags. This is useful for defining 249038032Speter a mailer which delivers to the same file regardless of the 249138032Speter recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 249238032Speter Do not assume the identity of a remote connection is root@localhost 249338032Speter if the remote connection closes the socket before the 249438032Speter remote identity can be queried. 249538032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 249638032Speter Some mailers, including procmail, require that the real 249738032Speter uid is left unchanged by sendmail. Problem noted by Per 249838032Speter Hedeland of Ericsson. 249938032Speter No longer is the src/obj*/Makefile selected from a large list -- it 250038032Speter is now generated using the information in BuildTools/OS/ -- 250138032Speter some of the details are determined dynamically via 250238032Speter BuildTools/bin/configure.sh. 250338032Speter The other programs in the sendmail distribution -- mail.local, 250438032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 250538032Speter the new Build method which creates an operating system 250638032Speter specific Makefile using the information in BuildTools. 250738032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 250838032Speter a failure on one message won't affect future messages to the 250938032Speter same host). This is necessary if the remote host sends 251038032Speter a 451 error if the domain of the sender does not resolve 251138032Speter as is common in anti-spam configurations. Problem noted 251238032Speter by Mitchell Blank Jr of Exec-PC. 251338032Speter New "discard" mailer for check_* rulesets and header checking 251438032Speter rulesets. If one of the above rulesets resolves to the 251538032Speter $#discard mailer, the commands will be accepted but the 251638032Speter message will be completely discarded after it is accepting. 251738032Speter This means that even if only one of the recipients 251838032Speter resolves to the $#discard mailer, none of the recipients 251938032Speter will receive the mail. Suggested by Brian Kantor. 252038032Speter All but the last cloned envelope of a split envelope were queued 252138032Speter instead of being delivered.

Patch from John Beck of Sun 262138032Speter Microsystems. 262238032Speter CONFIG: Increment version number of config file. 262338032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 262438032Speter map for the various maps. The default is hash. Patch from 262538032Speter Robert Harker of Harker Systems. 262638032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 262738032Speter directory for certain programs. 262838032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 262938032Speter local mail delivery. By the default, /usr/libexec/mail.local 263038032Speter is used. This is expected to be the mail.local shipped 263138032Speter with 8.9 which is LMTP capable. The path is based on the 263238032Speter new confEBINDIR m4 variable. 263338032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 263438032Speter FEATURE(smrsh). Note that this changes the default from 263538032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 263638032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 263738032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 263838032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 263938032Speter the user to setup different .forward files for 264038032Speter user+detail addressing. 264138032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 264238032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 264338032Speter DontProbeInterfaces, and DontBlameSendmail options. 264438032Speter CONFIG: by default do not allow relaying (that is, accepting mail 264538032Speter from outside your domain and sending it to another host 264638032Speter outside your domain). 264738032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 264838032Speter any site to any site. 264938032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 265038032Speter domain as defined by the 'm' class ($=m) to relay. 265138032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 265238032Speter the MX records of the host portion of an incoming recipient. 265338032Speter CONFIG: new FEATURE(access_db) which turns on the access database 265438032Speter feature. This database give you the ability to allow 265538032Speter or refuse to accept mail from specified domains for 265638032Speter administrative reasons. By default, names that are listed 265738032Speter as "OK" in the access db are domain names, not host names. 265838032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 265938032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 266038032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 266138032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 266238032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 266338032Speter of FEATURE(access_db) and class 'R' to lookup individual 266438032Speter host names only. 266538032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 266638032Speter using % addressing is used, e.g. user%site@othersite, 266738032Speter and othersite is in class 'R', the check_rcpt ruleset 266838032Speter will strip @othersite and recheck user@site for relaying. 266938032Speter This feature changes that behavior. It should not be 267038032Speter needed for most installations. 267138032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 267238032Speter domain portion of the mail sender is a local host. This 267338032Speter should only be used if absolutely necessary as it opens 267438032Speter a window for spammers. Patch from Randall S. Winchester of 267538032Speter the University of Maryland. 267638032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 267738032Speter block incoming mail destined for certain recipient 267838032Speter usernames, hostnames, or addresses. 267938032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 268038032Speter refused if the host part of the argument to MAIL FROM: cannot 268138032Speter be located in the host name service (e.g., DNS). 268238032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 268338032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 268438032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 268538032Speter MAIL FROM: senders which do not include a domain. 268638032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 268738032Speter Realtime Blackhole List. You can specify the RBL name 268838032Speter server to contact by specifying it as an optional argument. 268938032Speter The default is rbl.maps.vix.com. For details, see 269038032Speter http://maps.vix.com/rbl/. 269138032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 269238032Speter Local_check_rcpt from check_relay, check_mail, and 269338032Speter check_rcpt. Users with local rulesets should place the 269438032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 269538032Speter returns $#OK, the message is accepted. If the ruleset 269638032Speter returns a mailer, the appropriate action is taken, else 269738032Speter the return of the ruleset is ignored. 269838032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 269938032Speter default to support file, :include:, and program deliveries. 270038032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 270138032Speter pick the proper default value. See the SECURITY note 270238032Speter above for more information. 270338032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 270438032Speter no-op. Patch from Kari Hurtta of the Finnish 270538032Speter Meteorological Institute. 270638032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 270738032Speter daemon since DEC's /bin/mail will drop the envelope 270838032Speter sender if run as mailnull. See the Digital UNIX section 270938032Speter of src/README for more information. Problem noted by 271038032Speter Kari Hurtta of the Finnish Meteorological Institute. 271138032Speter CONFIG: .cf files are now stored in the same directory with the 271238032Speter .mc files instead of in the obj directory. 271338032Speter CONFIG: New options confSINGLE_LINE_FROM_HEADER, 271438032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 271538032Speter setting SingleLineFromHeader, AllowBogusHELO, and 271638032Speter MustQuoteChars respectively. 271738032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.

Problem noted by Alan Barrett of Internet Africa. 288438032Speter A combination of deferred delivery mode, a double bounce situation, 288538032Speter and the inability to save a bounce message to 288638032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 288738032Speter to postmaster but not remove the offending envelope from the 288838032Speter queue causing it to create a new bounce message each time the 288938032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 289038032Speter Associates. 289138032Speter Remove newlines from hostname information returned via DNS. There are 289238032Speter no known security implications of newlines in hostnames as 289338032Speter sendmail filters newlines in all vital areas; however, this 289438032Speter could cause confusing error messages. 289538032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 289664562Sgshapiro rejected if any of the specified addresses were bad. This 289738032Speter behavior was modified to only reject the bad addresses and not 289838032Speter the entire message.

From Tetsu Ushijima of the 301938032Speter Tokyo Institute of Technology. 302038032Speter Fix race condition that could cause the body of a message to be 302138032Speter lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of 302538032Speter Results Computing. 302638032Speter If a qf file was found in a mail queue directory that had a problem 302738032Speter (wrong ownership, bad format, etc.) and the file name was 302838032Speter exactly MAXQFNAME bytes long, then instead of being tried 302938032Speter once, it would be tried on every queue run. Problem noted 303038032Speter by Bryan Costales of Mercury Mail. 303138032Speter If the system supports an st_gen field in the status structure, 303238032Speter include it when reporting that a file has changed after open. 303338032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 303438032Speter This out to be checked as well as reported, since it is 303564562Sgshapiro theoretically possible for an attacker to remove a file after 303638032Speter it is opened and replace it with another file that has the 303738032Speter same i-number, but some filesystems (notably AFS) return 303838032Speter garbage in this field, and hence always look like the file 303938032Speter has changed. As a practical matter this is not a security 304038032Speter problem, since the files can be neither hard nor soft links, 304138032Speter and on no filesystem (that I am aware of) is it possible to 304238032Speter have two files on the same filesystem with the same i-number 304338032Speter simultaneously. 304438032Speter Delete the root Makefile from the distribution -- it is only for 304538032Speter use internally, and does not work at customer sites. 304638032Speter Fix botch that caused the second MAIL FROM: command in a single 304738032Speter transaction to clear the entire transaction.

This makes it possible to create a root 313338032Speter owned file in an arbitrary directory by inserting the symlink 313438032Speter into a writable directory after the initial lstat(2) check 313538032Speter determined that the file did not exist. The only verified 313638032Speter example of a system having these odd semantics for O_EXCL 313738032Speter and symbolic links was HP-UX prior to version 9.07. Most 313838032Speter systems do not have the problem, since a exclusive create 313938032Speter of a file disallows symbolic links. Systems that have been 314038032Speter verified to NOT have the problem include AIX 3.x, *BSD, 314138032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 314238032Speter and Ultrix. This is a potential exposure on systems that 314338032Speter have this bug and which do not have a MAILER-DAEMON alias 314438032Speter pointing at a legitimate account, since this will cause old 314538032Speter mail to be dropped in /var/tmp/dead.letter. 314638032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 314738032Speter if maps or alias files are in world writable directories. 314838032Speter If your system has alias maps in writable directories, it 314938032Speter is potentially possible for an attacker to replace the .db 315038032Speter (or .dir and .pag) files by symbolic links pointing at 315138032Speter another database; this can be used either to expose 315238032Speter information (e.g., by pointing an alias file at /etc/spwd.db 315338032Speter and probing for accounts), or as a denial-of-service attack 315438032Speter (by trashing the password database). The fix disallows 315538032Speter symbolic links entirely when rebuilding alias files or on 315638032Speter maps that are in writable directories, and always warns on 315738032Speter writable directories; 8.9 will probably consider writable 315838032Speter directories to be fatal errors. This does not represent an 315938032Speter exposure on systems that have alias files in unwritable 316038032Speter system directories. 316138032Speter SECURITY: disallow .forward or :include: files that are links (hard 316238032Speter or soft) if the parent directory (or any directory in the 316338032Speter path) is writable by anyone other than the owner. This is 316438032Speter similar to the previous case for user files. This change 316538032Speter should not affect most systems, but is necessary to prevent 316638032Speter an attacker who can write the directory from pointing such 316738032Speter files at other files that are readable only by the owner. 316838032Speter SECURITY: Tighten safechown rules: many systems will say that they 316938032Speter have a safe (restricted to root) chown even on files that 317038032Speter are mounted from another system that allows owners to give 317138032Speter away files. The new rules are very strict, trusting file 317238032Speter ownership only in those few cases where the system has 317338032Speter been verified to be at least as paranoid as necessary. 317438032Speter However, it is possible to relax the rules to partially 317538032Speter trust the ownership if the directory path is not world or 317638032Speter group writable. This might allow someone who has a legitimate 317738032Speter :include: file (referenced directly from /etc/aliases) to 317838032Speter become another non-root user if the :include: file is in a 317938032Speter non-writable directory on an NFS-mounted filesystem where 318038032Speter the local system says that giveaway is denied but it is 318138032Speter actually permitted. I believe this to be a very small set 318238032Speter of cases. If in doubt, do not point :include: aliases at 318338032Speter NFS-mounted filesystems. 318438032Speter SECURITY: When setting a numeric group id using the RunAsUser option 318538032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 318638032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 318764562Sgshapiro group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 318838032Speter The user id was still set properly.

Problem noted by 322138032Speter Richard Muirden of RMIT University. 322238032Speter Always print error messages during newaliases (-bi) even if the 322338032Speter ErrorMode is not set to "print". Fix from Gregory Neil 322438032Speter Shapiro. 322538032Speter Test mode could core dump if you did a /map lookup in an optional map 322638032Speter that could not be opened. Based on a fix from John Beck of 322738032Speter Sun Microsystems. 322838032Speter If DNS is misconfigured so that the last MX record tried points to 322938032Speter a host that does not have an A record, but other MX records 323038032Speter pointed to something reasonable, don't bounce the message 323138032Speter with a "host unknown" error. Note that this should really 323238032Speter be fixed in the zone file for the domain. Problem noted by 323338032Speter Joe Rhett of Navigist, Inc. 323438032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 323538032Speter the message as having been tried; otherwise the next queue 323638032Speter run will not realize that this is a second attempt and will 323738032Speter retry immediately. Problem noted by Bryan Costales of 323838032Speter Mercury Mail. 323938032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 324038032Speter will be run until the later setting of the clock is reached. 324138032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 324238032Speter Morgan Stanley. 324338032Speter If the load average rises above the cutoff threshold (above which 324438032Speter sendmail will not process the queue at all) during a queue 324538032Speter run, abort the queue run immediately. Problem noted by 324638032Speter Bryan Costales of Mercury Mail. 324738032Speter The variable queue processing algorithm (based on the message size, 324838032Speter number of recipients, message precedence, and job age) was 324938032Speter non-functional -- either the entire queue was processed or 325038032Speter none of the queue was processed. The updated algorithm 325138032Speter does no queue run if a single recipient zero size job will 325238032Speter not be run. 325338032Speter If there is a fatal ("panic") message that will cause sendmail to 325438032Speter die immediately, never hold the error message for future 325538032Speter printing. 325638032Speter Force ErrorMode=print in -bt mode so that all errors are printed 325738032Speter regardless of the setting of the ErrorMode option in the 325838032Speter configuration file. Patch from Gregory Neil Shapiro. 325938032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 326038032Speter routine available in one of the libraries. Use it in conf.h. 326138032Speter The -m (match only) flag now works on host class maps. 326238032Speter If class hash or btree maps are rebuilt, sendmail will now detect 326338032Speter this and reopen the map. Previously, they could give 326438032Speter erroneous results during a single message processing 326538032Speter (but would recover when the next message was received). 326638032Speter Don't delete zero length queue files when doing queue runs until the 326738032Speter files are at least ten minutes old. This avoids a potential 326838032Speter race condition: the creator creates the qf file, getting back 326938032Speter a file descriptor. The queue runner locks it and deletes it 327038032Speter because it is zero length. The creator then writes the 327138032Speter descriptor that is now for a disconnected file, and the 327238032Speter job goes away. Based on a suggestion by Bryan Costales. 327338032Speter When determining the "validated" host name ($_ macro), do a forward 327438032Speter (A) DNS lookup on the result of the PTR lookup and compare 327538032Speter results. If they differ or if the PTR lookup fails, tag the 327638032Speter address as "may be forged". 327738032Speter Log null connections (i.e., hosts that connect but do not do any 327838032Speter substantive activity on the connection before disconnecting; 327938032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 328038032Speter Always permit "writes" to /dev/null regardless of the link count. 328138032Speter This is safe because /dev/null is special cased, and no open 328238032Speter or write is ever actually attempted. Patch from Villy Kruse 328338032Speter of TwinCom. 328438032Speter If a message cannot be sent because of a 552 (exceeded storage 328538032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 328638032Speter was given, don't return the body in the bounce, since there 328738032Speter is a very good chance that the message will double-bounce. 328838032Speter Fix possible line truncation if a quoted-printable had an =00 escape 328938032Speter in the body. Problem noted by Charles Karney of the Princeton 329038032Speter Plasma Physics Laboratory. 329138032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 329238032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 329338032Speter Institute. 329438032Speter The MaxDaemonChildren option wasn't applying to queue runs as 329538032Speter documented. Note that this increases the potential denial 329638032Speter of service problems with this option: an attacker can 329738032Speter connect many times, and thereby lock out queue runs as well 329838032Speter as incoming connections. If you use this option, you should 329938032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 330038032Speter to avoid this attack. Failure to limit noted by Matthew 330138032Speter Dillon of BEST Internet Communications. 330238032Speter Always give a message in newaliases if alias files cannot be 330338032Speter opened instead of failing silently. Suggested by Gregory 330438032Speter Neil Shapiro. This change makes the code match the O'Reilly 330538032Speter book (2nd edition). 330638032Speter Some older versions of the resolver could return with h_errno == -1 330738032Speter if no name server could be reached, causing mail to bounce 330838032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 330938032Speter John Beck of SunSoft. 331038032Speter If a :include: file is owned by a user that does not have an entry 331138032Speter in the passwd file, sendmail could dereference a null pointer. 331238032Speter Problem noted by Satish Mynam of Sun Microsystems. 331338032Speter Take precautions to make sure that the SMTP protocol cannot get out 331438032Speter of sync if (for example) an alias file cannot be opened. 331538032Speter Fix a possible race condition that can cause a SIGALRM to come in 331638032Speter immediately after a SIGHUP, causing the new sendmail to die. 331738032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 331838032Speter from Villy Kruse of TwinCom. 331938032Speter Ignore improperly formatted SMTP reply codes. Previously these were 332038032Speter partially processed, which could cause confusing error 332138032Speter returns. 332238032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 332338032Speter on some architectures. 332438032Speter Portability: 332538032Speter A/UX: from Jim Jagielski of NASA/GSFC. 332638032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 332738032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 332838032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 332938032Speter defined. Problem reported by A Sun of the University 333038032Speter of Washington. 333138032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 333238032Speter the system rather than guessing at compile time. 333338032Speter Patch contributed by John Beck of Sun Microsystems. 333438032Speter Intel Paragon: from Wendy Lin of Purdue University. 333538032Speter GNU Hurd: from Miles Bader of the GNU project. 333638032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 333738032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 333838032Speter Unfortunately releasing them opens a race condition, 333938032Speter but there appears to be no fix for this. Patch from 334038032Speter Gregory Neil Shapiro. 334138032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 334238032Speter Solaris: a bug in strcasecmp caused characters with the 334338032Speter high order bit set to apparently randomly match 334438032Speter letters -- for example, $| (0233) matches "i" and "I". 334538032Speter Problem noted by John Gregson of the University of 334638032Speter Cambridge. 334738032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 334838032Speter Kari Hurtta. 334938032Speter IRIX 6.x: Create Makefiles for systems that claim to be 335038032Speter IRIX64 but are 6.2 or higher (so use the regular 335138032Speter IRIX Makefile). 335238032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 335338032Speter Problem noted by Eric Hagberg of Morgan Stanley. 335438032Speter CONFIG: Some canonification was still done for UUCP-like addresses 335538032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 335638032Speter Brian Candler. 335738032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 335838032Speter local names as local. Problem noted by Jeff Polk of BSDI; 335938032Speter fix provided by Gregory Neil Shapiro. 336038032Speter CONFIG: The "local:user" syntax entries in mailertables and other 336138032Speter "mailer:user" syntax locations returned an incorrect value 336238032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 336338032Speter CONFIG: Retain "+detail" information when forwarding mail to a 336438032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 336538032Speter Guenther of Gustavus Adolphus College. 336638032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 336738032Speter rules are the same as for aliasing. Based on a patch from 336838032Speter Gregory Neil Shapiro. 336938032Speter CONFIG: Break up parsing rules into several pieces; this should 337038032Speter have no functional change in this release, but makes it 337138032Speter possible to have better anti-spam rulesets in the future. 337238032Speter CONFIG: Disallow double dots in host names to avoid having the 337338032Speter HostStatusDirectory store status under the wrong name. 337438032Speter In some cases this can be used as a denial-of-service attack. 337538032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 337638032Speter Gregory Neil Shapiro. 337738032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 337838032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 337938032Speter don't include From_, and convert to 8-bit). Suggestions 338038032Speter from Kimmo Suominen and Roderick Schertler. 338138032Speter CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 338238032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 338338032Speter was specified, even when it wasn't. 338438032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 338538032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 338638032Speter "slip in" a symbolic link between the lstat(2) call and the 338738032Speter exclusive open. This is only a problem on System V derived 338838032Speter systems that allow an exclusive create on files that are 338938032Speter symbolic links pointing nowhere. 339038032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 339138032Speter not reset back to root, which on some systems would cause 339238032Speter later mailboxes to fail. Also, any partial message would 339338032Speter not be truncated, which could result in repeated deliveries. 339438032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 339538032Speter developers). 339638032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 339738032Speter change to the sendmail map code was made in 8.8.3. Problem 339838032Speter noted by Gregory Neil Shapiro. 339938032Speter MAKEMAP: Give warnings on file problems such as map files that are 340038032Speter symbolic links; although makemap is not setuid root, it is 340138032Speter often run as root and hence has the potential for the same 340238032Speter sorts of problems as alias rebuilds. 340338032Speter MAKEMAP: Change compilation so that it will link properly on 340438032Speter NEXTSTEP. 340538032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 340638032Speter Accept an optional list of arguments following the server 340738032Speter name for the ETRN arguments to use (instead of $=w). Other 340838032Speter miscellaneous bug fixes. From Christian von Roques via 340938032Speter John Beck of Sun Microsystems. 341038032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 341138032Speter Perl script converts GECOS information in the /etc/passwd 341238032Speter file into aliases, allowing for faster access to full name 341338032Speter lookups; it is also clever about adding aliases (to root) 341438032Speter for system accounts. 341538032Speter NEW FILES: 341638032Speter src/safefile.c 341738032Speter cf/ostype/gnuhurd.m4 341838032Speter cf/ostype/irix6.m4 341938032Speter contrib/passwd-to-alias.pl 342038032Speter src/Makefiles/Makefile.IRIX64.6.1 342138032Speter src/Makefiles/Makefile.IRIX64.6.x 342238032Speter RENAMED FILES: 342338032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 342438032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 342538032Speter 342638032Speter8.8.5/8.8.5 1997/01/21 342738032Speter SECURITY: Clear out group list during startup. Without this, sendmail 342838032Speter will continue to run with the group permissions of the caller, 342938032Speter even if RunAsUser is specified. 343038032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 343138032Speter to any known attack, but it's best to be conservative. 343238032Speter Suggested by Peter Wemm of DIALix. 343338032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 343438032Speter security implications. Patch from Alex Garthwaite of the 343538032Speter University of Pennsylvania. 343638032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 343738032Speter would truncate the address after "Full". Although the -f 343838032Speter syntax is incorrect (since it is in the envelope, it 343938032Speter shouldn't have comments and full names), the failure mode 344038032Speter was unnecessarily awful. 344138032Speter Fix a possible null pointer dereference when converting 8-bit data 344238032Speter to a 7-bit format. Problem noted by Jim Hutchins of 344338032Speter Sandia National Labs and David James of British Telecom. 344438032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 344564562Sgshapiro runs. Although this really shouldn't be used (F=9 is for 344638032Speter final delivery only, and using it on an SMTP mailer makes 344738032Speter it possible for a message to be converted from 8->7->8->7 344838032Speter bits several times), it shouldn't have failed with a syserr. 344938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 345038032Speter _Really_ fix the multiple :maildrop code in the user database 345138032Speter module. Patch from Roy Mongiovi of Georgia Tech. 345238032Speter Let F lines in the configuration file actually read root-only 345338032Speter files if the configuration file is safe. Based on a 345438032Speter patch from Keith Reynolds of SCO. 345538032Speter ETRN followed by QUIT would hold the connection open until the queue 345638032Speter run completed. Problem noted by Truck Lewis of TDK 345738032Speter Semiconductor Corp. 345838032Speter It turns out that despite the documentation, the TCP wrappers library 345938032Speter does _not_ log rejected connections. Do the logging ourselves. 346038032Speter Problem noted by Fletcher Mattox of the University of Texas 346138032Speter at Austin. 346238032Speter If sendmail finds a qf file in its queue directory that is an unknown 346338032Speter version (e.g., when backing out to an old version), the 346438032Speter error is reported on every queue run. Change it to only 346538032Speter give the error once (and rename the qf => Qf). Patch from 346638032Speter William A. Gianopoulos of Raytheon Company. 346738032Speter Start a new session when doing background delivery; currently it 346838032Speter ignored signals but didn't start a new signal, that caused 346938032Speter some problems if a background process tried to send mail 347038032Speter under certain circumstances. Problem noted by Eric Hagberg 347138032Speter of Morgan Stanley; fix from Kari Hurtta. 347238032Speter Simplify test for skipping a queue run to just check if the current 347338032Speter load average is >= the queueing load average. Previously 347438032Speter the check factored in some other parameters that caused it 347538032Speter to essentially never skip the queue run. Patch from Bryan 347638032Speter Costales. 347738032Speter If the SMTP server is running in "nullserver" mode (that is, it is 347838032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 347938032Speter (25) commands; this helps prevent a bad guy from putting 348038032Speter you into a tight loop as a denial-of-service attack. Based 348138032Speter on an e-mail conversation with Brad Knowles of AOL. 348238032Speter Slow down when too many "light weight" commands have been issued; 348338032Speter this helps prevent a class of denial-of-service attacks. 348438032Speter The current values and defaults are: 348538032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 348638032Speter MAXHELOCOMMANDS 3 HELO, EHLO 348738032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 348838032Speter MAXETRNCOMMANDS 8 ETRN 348938032Speter These will probably be configurable in a future release. 349064562Sgshapiro On systems that have uid_t typedefed to be an unsigned short, programs 349138032Speter that had the F=S flag and no U= equate would be invoked with 349238032Speter the real uid set to 65535 rather than being left unchanged. 349338032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 349438032Speter by Steve Hubert of the University of Washington, Seattle. 349538032Speter Mail that was Quoted-Printable encoded and had a soft line break on 349638032Speter the last line (i.e., an incomplete continuation) had the last 349738032Speter line dropped. Since this appears to be illegal it isn't 349838032Speter clear what to do with it, but flushing the last line seems 349938032Speter to be a better "fail soft" approach. Based on a patch from 350038032Speter Eric Hagberg. 350138032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 350238032Speter bogus HELO command still causes the "Polite people say HELO 350338032Speter first" error message. Problem pointed out by Chris Thomas 350438032Speter of UCLA; patch from John Beck of SunSoft. 350538032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 350638032Speter in PrivacyOptions. The -q shouldn't turn this command off. 350738032Speter Problem noted by Murray Kucherawy of Pacific Bell Internet; 350838032Speter based on a patch from Gregory Neil Shapiro of WPI. 350938032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 351038032Speter in a DATA transaction to be sticky; these can occur because 351138032Speter a message is too large, and smaller messages should still go 351238032Speter through. Problem noted by Matt Dillon of Best Internet 351338032Speter Communications. 351438032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 351538032Speter had been successfully delivered to the envelope sender. 351638032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 351738032Speter Gregory Neil Shapiro of WPI. 351838032Speter Give better diagnostics on long alias lines.

Problem noted by Ronan KERYELL 354638032Speter of Centre de Recherche en Informatique de l'�cole Nationale 354738032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 354838032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 354938032Speter such as LUSER_RELAY. This change permits the following 355038032Speter syntaxes: ``local:'' will send to the same user on the 355138032Speter local machine (e.g., in a mailertable entry for "host", 355238032Speter ``local:'' will cause an address addressed to user@host to 355338032Speter go to user on the local machone). ``local:user'' will send 355438032Speter to the named user on the local machine. ``local:user@host'' 355538032Speter is equivalent to ``local:user'' (the host is ignored). In 355638032Speter all cases, the original user@host is passed in $@ (i.e., the 355738032Speter detail information). Inspired by a report from Michael Fuhr. 355838032Speter CONFIG: Strip quotes from the first word of an "error:" host 355938032Speter indication. This lets you set (for example) the LUSER_RELAY 356038032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 356138032Speter of the \" so that the resulting string is properly quoted. 356238032Speter Problem noted by Gregory Neil Shapiro of WPI. 356338032Speter OP.ME: documentation was inconsistent about whether sendmail did a 356438032Speter NOOP or a RSET to probe the connection (it does a RSET). 356538032Speter Inconsistency noted by Deeran Peethamparam. 356638032Speter OP.ME: insert additional blank pages so it will print properly on 356738032Speter a duplex printer. From Matthew Black of Cal State University, 356838032Speter Long Beach. 356938032Speter 357071345Sgshapiro8.8.4/8.8.4 1996/12/02 357171345Sgshapiro SECURITY: under some circumstances, an attacker could get additional 357271345Sgshapiro permissions by hard linking to files that were group 357338032Speter writable by the attacker. The solution is to disallow any 357438032Speter files that have hard links -- this will affect .forward, 357538032Speter :include:, and output files. Problem noted by Terry 357638032Speter Kyriacopoulos of Interlog Internet Services. As a 357738032Speter workaround, set UnsafeGroupWrites -- always a good idea. 357838032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 357938032Speter is, it is possible to do a denial-of-service attack on 358038032Speter MX hosts that rely on the use of the null MX list. There 358138032Speter is no danger if you have this option turned off (the default). 358238032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 358338032Speter unsafe. I know of no specific attack against this, although 358438032Speter a denial-of-service attack is probably possible, but in theory 358538032Speter you should not be able to safely tweak anything that affects 358638032Speter the permissions that are used when mail is delivered. 358738032Speter Purgestat could go into an infinite loop if one of the host status 358838032Speter directories somehow became empty. Problem noted by Roy 358938032Speter Mongiovi of Georgia Tech. 359038032Speter Processes got "lost" when counting children due to a race condition. 359138032Speter This caused "proc_list_probe: lost pid" messages to be logged. 359238032Speter Problem noted by several people. 359338032Speter On systems with System V SIGCLD child signal semantics (notably AIX 359438032Speter and HP-UX), mail transactions would print the message "451 359538032Speter SMTP-MAIL: lost child: No child processes". Problem noted 359638032Speter by several people. 359738032Speter Miscellaneous compiler warnings on picky compilers (or when setting 359838032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 359938032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 360038032Speter not be persistent between runs, since they are based on the 360138032Speter message rather than the host. Problem noted by Matt Dillon 360238032Speter of Best Internet Communications. 360338032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 360438032Speter of NCR (a.k.a., AT&T Global Information Solutions). 360538032Speter Avoid the possibility of having a child daemon run to completion 360638032Speter (including closing the SMTP socket) before the parent has 360738032Speter had a chance to close the socket; this can cause the parent 360838032Speter to hang for a long time waiting for the socket to drain. 360938032Speter Patch from Don Lewis of TDK Semiconductor. 361038032Speter If the fork() failed in a queue run, the queue runners would not be 361138032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 361238032Speter Some error conditions in ETRN could cause output without an SMTP 361338032Speter status code. Problem noted by Don Lewis. 361438032Speter Multiple :maildrop addresses in the user database didn't work properly. 361538032Speter Patch from Roy Mongiovi of Georgia Tech. 361638032Speter Add ".db" automatically onto any user database spec that does not 361738032Speter already have it; this is for consistency with makemap, the 361838032Speter K line, and the documentation. Inconsistency pointed out 361938032Speter by Roy Mongiovi. 362038032Speter Allow sendmail to be properly called in nohup mode. Patch from 362138032Speter Kyle Jones of UUNET. 362238032Speter Change ETRN to ignore but still update host status files; previously 362338032Speter it would ignore them and not save the updated status, which 362438032Speter caused stale information to be maintained. Based on a patch 362538032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 362638032Speter ETRN ignore the MinQueueAge option. 362738032Speter Patch long term host status to recover more gracefully from an empty 362838032Speter host status file condition. Patch from NAKAMURA Motonori 362938032Speter of Kyoto University. 363038032Speter Several patches to signal handling code to fix potential race 363138032Speter conditions from Don Lewis. 363238032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 363338032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 363464562Sgshapiro 0/1 compilation flags. Note that DAEMON is an obsolete 363538032Speter compile flag; use NETINET instead. Solution based on a 363638032Speter patch from Bryan Costales. 363738032Speter PORTABILITY FIXES: 363838032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 363938032Speter /etc/security/passwd file when called as root. This 364038032Speter is very slow on some systems. To speed it up, use the 364138032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 364238032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 364338032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 364438032Speter Glicker of Burrelle's Information Service. 364538032Speter NEWS-OS 4.x: need a definition for MODE_T to compile.

Problem 368238032Speter noted by Eric Bishop of Virginia Tech. 368338032Speter When doing text-based host canonification (typically /etc/hosts 368438032Speter lookup), a null host name would match any /etc/hosts entry 368538032Speter with space at the end of the line. Problem noted by Steve 368638032Speter Hubert of the University of Washington, Seattle. 368738032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 368838032Speter Problem reported by Tom Smith of Digital Equipment Corp. 368938032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 369038032Speter size PACKETSZ (512) is not sufficient for some nameserver 369138032Speter answers containing very many resource records. The resolver 369238032Speter may also switch to TCP and retry if it detects UDP packet 369338032Speter overflow. Also, allow for the fact that the resolver 369438032Speter routines res_query and res_search return the size of the 369538032Speter *un*truncated answer in case the supplied answer buffer it 369638032Speter not big enough to accommodate the entire answer. Patch from 369738032Speter Eric Wassenaar. 369838032Speter Improvements to MaxDaemonChildren code. If you think you have too 369938032Speter many children, probe the ones you have to verify that they 370038032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 370138032Speter Also, do this probe before growing the vector of children 370238032Speter pids; this previously caused the vector to grow indefinitely 370338032Speter due to a race condition. Problem reported by Kyle Jones of 370438032Speter UUNET. 370538032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 370638032Speter O_EXLOCK to zero; this fools the map compilation code into 370738032Speter thinking that it can avoid race conditions by locking on open. 370838032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 370938032Speter Leif Erlingsson of Data Lege. 371038032Speter Always call res_init() on startup (if compiled in, of course) to 371138032Speter allow the sendmail.cf file to tweak resolver flags; without 371238032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 371338032Speter Andrew Sun of Merrill Lynch. 371438032Speter Improvements to host status printing code. Suggested by Steve Hubert 371538032Speter of the University of Washington, Seattle. 371638032Speter Change MinQueueAge option processing to do the check for the job age 371738032Speter when reading the queue file, rather than at the end; this 371838032Speter avoids parsing the addresses, which can do DNS lookups. 371938032Speter Problem noted by John Beck of InReference, Inc. 372038032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 372138032Speter properly escaped. Problem noted by Peter Nilsson of the 372238032Speter University of Linkoping. 372338032Speter In some cases, sendmail would retain root permissions during queue 372438032Speter runs even if RunAsUser was set. Problem noted by Mark 372538032Speter Thomas of Mark G. Thomas Consulting. 372638032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 372738032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 372838032Speter the envelope, and the receiving SMTP server speaks DSN, then 372938032Speter the DSN would be both generated locally and propagated to the 373038032Speter other end. 373138032Speter The U= mailer field didn't correctly extract the group id if the 373238032Speter user id was numeric.

If this option is null (as 380638032Speter opposed to undefined) it can cause "null signature" syserrs 380738032Speter on illegal host names. 380838032Speter If a Base64 encoded text/plain message has no trailing newline in 380938032Speter the encoded text, conversion back to 8 bits will drop the 381038032Speter final line. Problem noted by Pierre David. 381138032Speter If running with a RunAsUser, sendmail would give bogus "cannot 381238032Speter setuid" (or seteuid, or setreuid) messages on some systems. 381338032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 381438032Speter Always print error messages in -bv mode -- previously, -bv would 381538032Speter be absolutely silent on errors if the error mode was sent 381638032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 381738032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 381838032Speter term host status. This is necessary because it is common 381938032Speter to do this when you know a host has just come back up. 382038032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 382138032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 382238032Speter University of Leicester. 382338032Speter If a service (such as NIS) is specified as the last entry in the 382438032Speter service switch, but that service is not compiled in, sendmail 382538032Speter would return a temporary failure when an entry was not found 382638032Speter in the map. This caused the message to be queued instead of 382738032Speter bouncing immediately.

Patch from Per Hedeland of Ericsson. 386438032Speter The DaemonPortOptions suboption to bind to a particular address was 386538032Speter incorrect and nonfunctional due to a misunderstanding of the 386638032Speter semantics of binding on a passive socket.

In order to avoid 387138032Speter trashing memory, the buffer for all names has only been 387238032Speter slightly increased in size, to 12.8K from 10.2K -- this means 387338032Speter that if a single name had 100 MX records, the average size 387438032Speter of those records could not exceed 128 bytes. Requested by 387538032Speter Brad Knowles of America On Line. 387638032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 387738032Speter Urged by Dan Bernstein of U.C. Berkeley. 387838032Speter Print q_statdate and q_specificity in address structure debugging 387938032Speter printout. 388038032Speter Expand MCI structure flag bits for debugging output. 388138032Speter Support IPv6-style domain literals, which can have colons between 388238032Speter square braces. 388338032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 388438032Speter this is an attempt to track down a bug that one person seems 388538032Speter to be having (it may be a Solaris bug!). 388638032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 388738032Speter this caused the NOTIFY info to sometimes be lost. Problem 388838032Speter pointed out by Claus Assmann of the 388938032Speter Christian-Albrechts-University of Kiel. 389038032Speter The statistics gathered in the sendmail.st file were too high; in 389138032Speter some cases failures (e.g., user unknown or temporary failure) 389238032Speter would count as a delivery as far as the statistics were 389338032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 389438032Speter Systems that don't have flock() would not send split envelopes in 389538032Speter the initial run. Problem pointed out by Leonard Zubkoff of 389638032Speter Dandelion Digital. 389738032Speter Move buffer overflow checking -- these primarily involve distrusting 389838032Speter results that may come from NIS and DNS. 389938032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 390038032Speter include <paths.h> and hence had the wrong pathnames for a few 390138032Speter things like /var/tmp. Reported by Matthew Green. 390238032Speter Conditions were reversed for the Priority: header, resulting in all 390338032Speter values being interpreted as non-urgent except for non-urgent, 390438032Speter which was interpreted as normal. Patch from Bryan Costales. 390538032Speter The -o (optional) flag was being ignored on hash and btree maps 390638032Speter since 8.7.2. Fix from Bryan Costales. 390738032Speter Content-Types listed in class "q" will always be encoded as 390838032Speter Quoted-Printable (or more accurately, will never be encoded 390938032Speter as base64). The class can have primary types (e.g., "text") 391064562Sgshapiro or full types (e.g., "text/plain"). Based on a suggestion by 391138032Speter Marius Olafsson of the University of Iceland. 391238032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 391338032Speter dialogue) so it can be passed to programs in mailers. 391438032Speter Define ${bodytype} to be the body type (from the -B flag or the 391538032Speter BODY= ESMTP parameter) so it can be passed to programs in 391638032Speter mailers. 391738032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 391838032Speter flag is set in the mailer descriptor. Suggested by John 391938032Speter Myers of CMU. 392038032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 392138032Speter The command takes a host name; data for that host is 392238032Speter immediately (and asynchronously) flushed. Because this shares 392338032Speter the -qR implementation, other hosts may be attempted, but 392438032Speter there should be no security implications. Implementation 392538032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 392638032Speter Add three new command line flags to pass in DSN parameters: -V envid 392738032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 392838032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 392938032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 393038032Speter that the -N flag applies to all recipients; there is no way 393138032Speter to specify per-address notifications on the command line, 393238032Speter nor is there an equivalent for the ORCPT= per-address 393338032Speter parameter. 393438032Speter Restore LogLevel option to be safe (it can only be increased); 393538032Speter apparently I went into paranoid mode between 8.6 and 8.7 393638032Speter and made it unsafe. Pointed out by Dabe Murphy of the 393738032Speter University of Maryland. 393838032Speter New logging on log level 15: all SMTP traffic. Patches from 393938032Speter Andrew Gross of San Diego Supercomputer Center. 394038032Speter NetInfo property value searching code wasn't stopping when it found 394138032Speter a match. This was causing the wrong values to be found (and 394238032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 394338032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 394438032Speter out by Bill Wisner of Electronics for Imaging that you can't 394538032Speter use the bracket address form for the MAIL_HUB macro, since 394638032Speter that causes the brackets to remain in the envelope recipient 394738032Speter address used for delivery. The simple fix (stripping off the 394838032Speter brackets in the config file) breaks the use of IP literal 394938032Speter addresses. This flag will solve that problem. 395038032Speter Add MustQuoteChars option. This is a list of characters that must 395138032Speter be quoted if they are found in the phrase part of an address 395238032Speter (that is, the full name part). The characters @,;:\()[] are 395338032Speter always in this list and cannot be removed. The default is 395438032Speter this list plus . and ' to match RFC 822. 395538032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 395638032Speter that do not include a host name for back compatibility with 395738032Speter some stupid SMTP clients. Setting this violates RFC 1123 395838032Speter section 5.2.5. 395938032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 396038032Speter rejecting connections if it has more than this many 396138032Speter outstanding children accepting mail. Note that you may 396238032Speter see more processes than this because of outgoing mail; this 396338032Speter is for incoming connections only. 396438032Speter Add ConnectionRateThrottle option. If set to a positive value, the 396538032Speter number of incoming SMTP connections that will be permitted 396638032Speter in a single second is limited to this number. Connections are 396738032Speter not refused during this time, just deferred. The intent is to 396838032Speter flatten out demand so that load average limiting can kick in. 396938032Speter It is less radical than MaxDaemonChildren, which will stop 397038032Speter accepting connections even if all the connections are idle 397138032Speter (e.g., due to connection caching). 397238032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 397338032Speter specifies how long cached information about the state of a 397438032Speter host will be kept before they are considered stale and the 397538032Speter host is retried. If you are using persistent host status 397638032Speter (i.e., the HostStatusDirectory option is set) this will apply 397738032Speter between runs; otherwise, it applies only within a single queue 397838032Speter run and hence is useful only for hosts that have large queues 397938032Speter that take a very long time to run. 398038032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 398138032Speter into being a single line even if they had newlines in them 398238032Speter when read. This is to get around a botch in Lotus Notes. 398338032Speter Text class maps were totally broken -- if you ever retrieved the last 398438032Speter item in a table it would be truncated. Problem noted by 398538032Speter Gregory Neil Shapiro of WPI. 398638032Speter Extend the lines printed by the mailq command (== the -bp flag) when 398738032Speter -v is given to 120 characters; this allows more information 398838032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 398938032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 399038032Speter this was treated as end-of-input. Problem noted by Bryan 399138032Speter Costales. 399238032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 399338032Speter to the queue file. Fix from John Hughes of Atlantic 399438032Speter Technologies, Inc. 399538032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 399638032Speter if this happens in a queue run it can cause nasty delays. 399738032Speter Problem noted by Mark Horton of AT&T. 399838032Speter If userdb entries pointed to userdb entries, and there were multiple 399938032Speter values for a given key, the database cursor would get 400038032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 400138032Speter of Georgia Tech. Fixed by reading all the values and creating 400238032Speter a comma-separated list; thus, the -v output will be somewhat 400338032Speter different for this case. 400438032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 400538032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 400638032Speter of Stanford University. 400738032Speter When envelopes were split due to aliases with owner- aliases, and 400838032Speter there was some error on one of the lists, more than one of 400938032Speter the owners would get the message. Problem pointed out by 401038032Speter Roy Mongiovi of Georgia Tech. 401138032Speter Detect excessive recursion in macro expansions, e.g., $X defined 401238032Speter in terms of $Y which is defined in terms of $X. Problem 401338032Speter noted by Bryan Costales; patch from Eric Wassenaar. 401438032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 401538032Speter some cases get trashed causing bogus From_ lines. Fix from 401638032Speter Kyle Jones of UUNET. 401738032Speter When doing load average initialization, if the nlist call for avenrun 401838032Speter failed, the second and subsequent lookups wouldn't notice 401938032Speter that fact causing bogus load averages to be returned. Noted 402038032Speter by Casper Dik of Sun Holland. 402138032Speter Fix problem with incompatibility with some versions of inet_aton that 402238032Speter have changed the return value to unsigned, so a check for an 402338032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 402438032Speter This could cause mail to addresses such as [foo.com] to bounce 402538032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 402638032Speter Pasteur Institute. 402738032Speter DSNs were inconsistent if a failure occurred during the DATA phase 402838032Speter rather than the RCPT phase: the Action: would be correct, but 402938032Speter the detailed status information would be wrong. Problem noted 403038032Speter by Bob Snyder of General Electric Company. 403138032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 403238032Speter that this is the initial MUA->MTA submission. The flag current 403338032Speter does nothing, but in future releases (when MUAs start using 403438032Speter these flags) it will probably turn on things like DNS 403538032Speter canonification. 403638032Speter Default end-of-line string (E= specification on mailer [M] lines) 403738032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 403838032Speter mailers. 403938032Speter Change the internal definition for the *file* and *include* mailers 404038032Speter to have $u in the argument vectors so that they aren't 404138032Speter misinterpreted as SMTP mailers and thus use \r\n line 404238032Speter termination. This will affect anyone who has redefined 404338032Speter either of these in their configuration file. 404438032Speter Don't assume that IDENT servers close the connection after a query; 404538032Speter responses can be newline terminated. From Terry Kennedy of 404638032Speter St. Peter's College. 404738032Speter Avoid core dumps on erroneous configuration files that have 404838032Speter $#mailer with nothing following. From Bryan Costales. 404938032Speter Avoid null pointer dereference with high debug values in unlockqueue. 405038032Speter Fix from Randy Martin of Clemson University. 405138032Speter Fix possible buffer overrun when expanding very large macros. Fix 405238032Speter from Kyle Jones of UUNET. 405338032Speter After 25 EXPN or VRFY commands, start pausing for a second before 405438032Speter processing each one. This avoids a certain form of denial 405538032Speter of service attack. Potential attack pointed out by Bryan 405638032Speter Costales. 405738032Speter Allow new named (not numbered!) config file rules to do validity 405838032Speter checking on SMTP arguments: check_mail for MAIL commands and 405938032Speter check_rcpt for RCPT commands. These rulesets can do anything 406038032Speter they want; their result is ignored unless they resolve to the 406138032Speter $#error mailer, in which case the indicated message is printed 406238032Speter and the command is rejected. Similarly, the check_compat 406338032Speter ruleset is called before delivery with "from_addr $| to_addr" 406438032Speter (the $| is a meta-symbol used to separate the two addresses); 406538032Speter it can give a "this sender can't send to this recipient" 406638032Speter notification. Note that this patch allows $| to stand alone 406738032Speter in rulesets. 406838032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 406938032Speter that have the name, IP address, and port number (respectively) 407038032Speter of the SMTP client (that is, the entity at the other end of 407138032Speter the connection. These can be used in (e.g.) check_rcpt to 407238032Speter verify that someone isn't trying to relay mail through your 407338032Speter host inappropriately. Be sure to use the deferred evaluation 407438032Speter form, for example $&{client_name}, to avoid having these bound 407538032Speter when sendmail reads the configuration file. 407638032Speter Add new config file rule check_relay to check the incoming connection 407738032Speter information. Like check_compat, it is passed the host name 407838032Speter and host address separated by $| and can reject connections 407938032Speter on that basis. 408038032Speter Allow IDA-style recursive function calls. Code contributed by Mark 408138032Speter Lovell and Paul Vixie. 408238032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 408338032Speter a virtual UUCP address using either a domain address or the $k 408438032Speter macro. Based on code contributed by Mark Lovell and Paul 408538032Speter Vixie. 408638032Speter Add Stanford LDAP map. Requires special libraries that are not 408738032Speter included with sendmail. Contributed by Booker C. Bense 408838032Speter <bbense@networking.stanford.edu>; contact him for support. 408938032Speter See also the src/READ_ME file. 409038032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 409138032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 409238032Speter only for debugging deep bits of code where it is important to 409338032Speter distinguish between the single-character metasymbol $+ and the 409438032Speter two characters $, +. 409538032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 409638032Speter debug_dumpstate. 409738032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 409838032Speter files that are group writable are considered "unsafe" -- that 409938032Speter is, programs and files referenced from such files are not 410038032Speter valid recipients. 410138032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 410238032Speter name that was not in DNS or was a domain-literal. Problem 410338032Speter noted by Tom May. 410438032Speter Change the introduction to error messages to more clearly delineate 410538032Speter permanent from temporary failures; if both existed in a 410638032Speter single message it could be confusing. Suggested by John 410738032Speter Beck of InReference, Inc. 410838032Speter The IngoreDot (i) option didn't work for lines that were terminated 410938032Speter with CRLF. Problem noted by Ted Stockwell of Secure 411038032Speter Computing Corporation. 411138032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 411238032Speter message headers. Problem reported by Matt Dillon of Best 411338032Speter Internet Communications. 411438032Speter Check for bogus characters in the 0200-0237 range; since these are 411538032Speter used internally, very strange errors can occur if those 411638032Speter characters appear in headers. Problem noted by Anders Gertz 411738032Speter of Lysator. 411838032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 411938032Speter recipient mailer has the F=9 flag set, and only works on 412038032Speter text/plain body types. Code contributed by Marius Olafsson 412138032Speter of the University of Iceland. 412238032Speter Special case "postmaster" name so that it is always treated as lower 412338032Speter case in alias files regardless of configuration settings; 412438032Speter this prevents some potential problems where "Postmaster" or 412538032Speter "POSTMASTER" might not match "postmaster". In most cases 412638032Speter this change is a no-op. 412738032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 412838032Speter Costales. 412938032Speter The -a map flag was ignored for dequote maps. Problem noted by 413038032Speter Bryan Costales. 413138032Speter Fix core dump when a lookup of a class "prog" map returns no 413238032Speter response. Patch from Bryan Costales. 413338032Speter Log instances where sendmail is deferring or rejecting connections 413438032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 413538032Speter Include port number in process title for network daemons. Suggested 413638032Speter by Kyle Jones of UUNET. 413738032Speter Send ``double bounces'' (errors that occur when sending an error 413838032Speter message) to the address indicated in the DoubleBounceAddress 413938032Speter option (default: postmaster). Previously they were always 414038032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 414138032Speter Add new mode, -bD, that acts like -bd in all respects except that 414238032Speter it runs in foreground. This is useful for using with a 414338032Speter wrapper that "watches" system services. Suggested by Kyle 414438032Speter Jones of UUNET. 414538032Speter Fix botch in spacing around (parenthesized) comments in addresses 414638032Speter when the comment comes before the address. Patch from 414738032Speter Motonori Nakamura of Kyoto University. 414838032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 414938032Speter that are being bounced to postmaster, rather than "Returned 415038032Speter mail". This permits the person who is postmaster more 415138032Speter easily determine what messages are to their role as 415238032Speter postmaster versus bounces to mail they actually sent. Based 415338032Speter on a suggestion by Motonori Nakamura. 415438032Speter Add new value "time" for QueueSortOrder option; this causes the queue 415538032Speter to be sorted strictly by the time of submission. Note that 415638032Speter this can cause very bad behavior over slow lines (because 415738032Speter large jobs will tend to delay small jobs) and on nodes with 415838032Speter heavy traffic (because old things in the queue for hosts that 415938032Speter are down delay processing of new jobs). Also, this does not 416038032Speter guarantee that jobs will be delivered in submission order 416138032Speter unless you also set DeliveryMode=queue. In general, it should 416238032Speter probably only be used on the command line, and only in 416338032Speter conjunction with -qRhost.domain. In fact, there are very few 416438032Speter cases where it should be used at all. Based on an 416538032Speter implementation by Motonori Nakamura. 416638032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 416738032Speter the same manner as other rulesets. Previously a temporary 416838032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 416938032Speter of Stanford University. 417038032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 417138032Speter 5yz (permanent failure) code. The next MX host will still be 417238032Speter tried if the connection cannot be opened in the first place 417338032Speter or if the MAIL command returns a 4yz (temporary failure) code. 417438032Speter (It's hard to know what to do here, since neither RFC 974 nor 417538032Speter RFC 1123 specify when to proceed to the next MX host.) 417638032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 417738032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 417838032Speter This causes map lookups that get a temporary failure (e.g., 417938032Speter name server failure) to _not_ defer the delivery of the 418038032Speter message. This should only be used if your configuration file 418138032Speter is prepared to do something sensible in this case. Based on 418238032Speter an idea by Gregory Shapiro of WPI. 418338032Speter Fix problem finding network interface addresses. Patch from 418438032Speter Motonori Nakamura. 418538032Speter Don't reject qf entries that are not owned by your effective uid if 418638032Speter you are not running setuid; this makes management of certain 418738032Speter kinds of firewall setups difficult. Patch suggested by 418838032Speter Eamonn Coleman of Qualcomm. 418938032Speter Add persistent host status. This keeps the information normally 419038032Speter maintained within a single queue run in disk files that are 419138032Speter shared between sendmail instances. The HostStatusDirectory 419238032Speter is the directory in which the information is maintained. If 419338032Speter not set, persistent host status is turned off. If not a full 419438032Speter pathname, it is relative to the queue directory. A common 419538032Speter value is ".hoststat". 419638032Speter There are also two new operation modes: 419738032Speter * -bh prints the status of hosts that have had recent 419838032Speter connections. 419938032Speter * -bH purges the host statuses. No attempt is made to save 420038032Speter recent status information. 420138032Speter This feature was originally written by Paul Vixie of Vixie 420238032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 420338032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 420438032Speter with my insistence that things fit cleanly into the V8 420538032Speter framework is gratefully appreciated. 420638032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 420738032Speter operate). Avoids letting two sendmails on the local machine 420838032Speter open connections to the same remote host at the same time. 420938032Speter This reduces load on the other machine, but can cause mail to 421038032Speter be delayed (for example, if one sendmail is delivering a huge 421138032Speter message, other sendmails won't be able to send even small 421238032Speter messages). Also, it requires another file descriptor (for the 421338032Speter lock file) per connection, so you may have to reduce 421438032Speter ConnectionCacheSize to avoid running out of per-process 421538032Speter file descriptors. Based on the persistent host status code 421638032Speter contributed by Paul Vixie and Mark Lovell. 421738032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 421838032Speter SafeFileEnvironment option is set. Problem noted by Bryan 421938032Speter Costales. 422043730Speter The -qR flag mistakenly matched flags in the "R" line of the queue 422138032Speter file. Problem noted by Bryan Costales. 422238032Speter If a job was aborted using the interrupt signal (e.g., control-C from 422338032Speter the keyboard), on some occasions an empty df file would be 422438032Speter left around; these would collect in the queue directory. 422538032Speter Problem noted by Bryan Costales. 422638032Speter Change the makesendmail script to enhance the search for Makefiles 422738032Speter based on release number. For example, on SunOS 5.5.1, it will 422838032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 422938032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 423038032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 423138032Speter Webmasters. 423238032Speter When creating maps using "newaliases", always map the keys to lower 423338032Speter case when creating the map unless the -f flag is specified on 423438032Speter the map itself. Previously this was done based on the F=u 423538032Speter flag in the local mailer, which meant you could create aliases 423638032Speter that you could never access. Problem noted by Bob Wu of DEC. 423738032Speter When a job was read from the queue, the bits causing notification on 423838032Speter failure or delay were always set. This caused those 423938032Speter notifications to be sent even if NOTIFY=NEVER had been 424038032Speter specified. Problem noted by Steve Hubert of the University 424138032Speter of Washington, Seattle. 424238032Speter Add new configurable routine validate_connection (in conf.c). This 424338032Speter lets you decide if you are willing to accept traffic from 424438032Speter this host. If it returns FALSE, all SMTP commands will return 424538032Speter "550 Access denied". -DTCPWRAPPERS will include support for 424638032Speter TCP wrappers; you will need to add -lwrap to the link line. 424738032Speter (See src/READ_ME for details.) 424838032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 424938032Speter bounces. Some people seemed to think that this could be 425038032Speter confusing (even though it is true). Suggested by Motonori 425138032Speter Nakamura. 425238032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 425338032Speter user early in processing to avoid potential security problems. 425438032Speter However, this means that all .forward and :include: files must 425538032Speter be readable by that user, and all files to be written must be 425638032Speter writable by that user and all programs will be executed by that 425738032Speter user. It is also incompatible with the SafeFileEnvironment 425838032Speter option. In other words, it may not actually add much to 425938032Speter security. However, it should be useful on firewalls and other 426038032Speter places where users don't have accounts and the aliases file is 426138032Speter well constrained. 426238032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 426338032Speter only on the first attempt to delivery to an address. It could 426438032Speter be set to be lower than Timeout.connect on the principle that 426538032Speter the mail should go through quickly to responsive hosts; less 426638032Speter responsive hosts get to wait for the next queue run. 426738032Speter Fix a problem on Solaris that occasionally causes programs 426838032Speter (such as vacation) to hang with their standard input connected 426938032Speter to a UDP port. It also created some signal handling problems. 427038032Speter The problems turned out to be an interaction between vfork(2) 427138032Speter and some of the libraries, particularly NIS/NIS+. I am 427264562Sgshapiro indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 427338032Speter Change user class map to do the same matching that actual delivery 427438032Speter will do instead of just a /etc/passwd lookup. This adds 427538032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 427638032Speter The Timeout.* options are not safe -- they can be used to create a 427738032Speter denial-of-service attack. Problem noted by Christophe 427838032Speter Wolfhugel. 427938032Speter Don't send PostmasterCopy messages in the event of a "delayed" 428038032Speter notification. Suggested by Barry Bouwsma. 428138032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 428238032Speter option is set, since this disables VERB mode. Suggested 428338032Speter by John Hawkinson of MIT. 428438032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 428538032Speter by Motonori Nakamura of Kyoto University. 428638032Speter Only queue messages on transient .forward open failures if there 428738032Speter were no successful opens. The previous behavior caused it 428838032Speter to queue even if a "fall back" .forward was found. Problem 428938032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 429038032Speter and Computer Science (DISCS), NUS, Singapore. 429138032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 429238032Speter is bouncing because of a MIME error during 8->7 bit conversion; 429338032Speter the encapsulated message will bounce again, causing a loop. 429438032Speter Problem noted by Steve Hubert of the University of Washington. 429538032Speter Create xf (transcript) files using the TempFileMode option value 429638032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 429738032Speter National University of Singapore. 429838032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 429938032Speter detect cases where DefaultUid is set to something that the 430038032Speter system can't cope with. 430138032Speter PORTABILITY FIXES: 430238032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 430338032Speter Atlas International. 430438032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 430538032Speter <bicknell@ufp.org>. 430638032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 430738032Speter work on the first recipient of a message due to a 430838032Speter bug in the getpwent family. If this is something you 430938032Speter use, you can define DEC_OSF_BROKEN_GETPWENT=1 for a 431038032Speter workaround.

Noted by David Linn of 434738032Speter Vanderbilt University. 434838032Speter Solaris changes for praliases, makemap, mailstats, and smrsh. 434938032Speter Previously you had to add -DSOLARIS in Makefile.dist; 435038032Speter this auto-detects. Based on a patch from Randall 435143730Speter Winchester of the University of Maryland. 435238032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 435338032Speter Robert La Ferla of Hot Software. 435438032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 435538032Speter (where "code" is an exit status) on domains (previously 435638032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 435738032Speter Foundation. 435838032Speter CONFIG: hooks for IPv6-style domain literals. 435938032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 436038032Speter if it is undefined the AliasFile option is never set; this 436138032Speter should be transparent for most everyone. Suggested by John 436238032Speter Myers of CMU. 436338032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 436438032Speter domain listed in $=w is masqueraded. With it, only those 436538032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 436638032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 436738032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 436838032Speter hosts under those domains as well as the domain headers 436938032Speter themselves. For example, if a configuration had 437038032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 437138032Speter foo.com would be masqueraded; with it, *.foo.com would be 437238032Speter masqueraded as well. Based on an implementation by Richard 437338032Speter (Pug) Bainter of U. Texas. 437438032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 437538032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 437638032Speter Keys are user names; values are outgoing mail addresses. Yes, 437738032Speter this does overlap with the user database, and figuring out 437838032Speter just when to use which one may be tricky. Based on code 437938032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 438038032Speter from Per Hedeland of Ericsson. 438138032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 438238032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 438338032Speter Keys are either fully qualified addresses or just the host 438438032Speter part (with the @ sign). For example, a table containing: 438538032Speter info@foo.com foo-info 438638032Speter info@bar.com bar-info 438738032Speter @baz.org jane@elsewhere.net 438838032Speter would send all mail destined for info@foo.com to foo-info 438938032Speter (which is presumably an alias), mail addressed to info@bar.com 439038032Speter to bar-info, and anything addressed to anyone at baz.org will 439138032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 439238032Speter and baz.org must all be in $=w. Based on discussions with 439338032Speter a great many people. 439438032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 439538032Speter Suggested by Richard Bainter. 439638032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 439738032Speter "fax" mailer. 439838032Speter CONFIG: allow mailertable entries to resolve to local:user; this 439938032Speter passes the original user@host in to procmail-style local 440038032Speter mailers as the "detail" information to allow them to do 440138032Speter additional clever processing. From Joe Pruett of 440238032Speter Teleport Corporation. Delivery to the original user can 440338032Speter be done by specifying "local:" (with nothing after the colon). 440438032Speter CONFIG: allow any context that takes "mailer:domain" to also take 440538032Speter "mailer:user@domain" to force mailing to the given user; 440638032Speter "local:user" can also be used to do local delivery. This 440738032Speter applies on *_RELAY and in the mailertable entries. Based 440838032Speter on a suggestion by Ribert Kiessling of Easynet. 440938032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 441038032Speter limits the possible domains; this reduces the number of DNS 441138032Speter lookups required to support this feature. For example, 441238032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 441338032Speter to domains under my.site.com. Code contributed by Anthony 441438032Speter Thyssen <anthony@cit.gu.edu.au>. 441538032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 441638032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 441738032Speter of WPI. 441838032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 441938032Speter event you have to define local mailers. Suggested by 442038032Speter Gregory Shapiro of WPI. 442138032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 442238032Speter be misinterpreted as a list:...; syntax. Based on a patch by 442338032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 442438032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 442538032Speter remotely connected. The address host!user was being 442638032Speter converted to host!user@thishost instead of host!user@uurelay. 442738032Speter Problem noted by William Gianopoulos of Raytheon Company. 442838032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 442938032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 443038032Speter "User has moved"; the former wording was confusing if the 443138032Speter new address is still on the local host. Based on a suggestion 443238032Speter by Andreas Luik. 443338032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 443438032Speter However, the class is not pre-initialized to contain root. 443538032Speter Suggested by Gregory Neil Shapiro. 443638032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 443738032Speter Wolfhugel. 443838032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 443938032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 444038032Speter well: this produces a slightly different mailbox format (no 444138032Speter Content-Length: headers), file ownerships and modes are 444238032Speter different (not owned by group mail; mode 600 instead of 660), 444338032Speter and the local mailer flags will have to be tweaked (make them 444438032Speter match bsd4.4) in order to use this mailer. Patches from Paul 444538032Speter Hammann of the Missouri Research and Education Network. 444638032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 444738032Speter was a delivery error, such as if the ownership on the file 444838032Speter was wrong or the mode changed between the initial stat and 444938032Speter the open.

They were not 453538032Speter properly repaired in 8.7.1. 453638032Speter Completely delete the Bcc: header if and only if there are other 453738032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 453838032Speter last being a historic botch, of course). If Bcc: is the 453938032Speter only recipient header in the message, its value is tossed, 454038032Speter but the header name is kept. The old behavior (always keep 454138032Speter the header name and toss the value) allowed primary recipients 454238032Speter to see that a Bcc: went to _someone_. 454338032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 454438032Speter sender to <address> using -f'' syslog messages.

This error caused hard 455438032Speter bounces when it should have requeued. 455538032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 455638032Speter owned by bar mode 700 and inbox being setuid bar stopped 455738032Speter working properly due to excessive paranoia.

From Tom Moore of AT&T GIS. 468738032Speter Shorten parameters passed to syslog() in some contexts to avoid a 468838032Speter bug in many vendors' implementations of that routine. Although 468938032Speter this isn't really a bug in sendmail per se, and my solution 469038032Speter has to assume that syslog() has at least a 1K buffer size 469138032Speter internally (I know some vendors have shortened this 469238032Speter dramatically -- they're on their own), sendmail is a popular 469338032Speter target. Also, limit the size of %s arguments in sprintf. 469438032Speter These both have possible security implications. Solutions 469538032Speter suggested by Casper Dik of Sun's Network Security Group 469638032Speter (Holland), Mark Seiden, and others. 469738032Speter Fix a problem that might cause a non-standard -B (body type) 469838032Speter parameter to be passed to the next server with undefined 469938032Speter results.

Fixes from Randy 470938032Speter Martin <WOLF@CLEMSON.EDU> 471038032Speter When sendmail starts up on systems that have no fully qualified 471138032Speter domain name (FQDN) anywhere in the first matching host map 471238032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 471338032Speter sendmail would sleep to try to find a FQDN, which it really 471438032Speter really needs. This has been changed to fall through to the 471538032Speter next map type if it can't find a FQDN -- i.e., if the hosts 471638032Speter file doesn't have a FQDN, it will try dns even though the 471738032Speter short name was found in /etc/hosts. This is probably a crock, 471838032Speter but many people have hosts files without FQDNs. Remember: 471938032Speter domain names are your friends. 472038032Speter Log a high-priority message if you can't find your FQDN during startup. 472138032Speter Suggested by Simon Barnes of Schlumberger Limited. 472238032Speter When using Hesiod, initialize it early to improve error reporting. 472338032Speter Patch from Don Lewis of Silicon Systems, Inc. 472438032Speter Apparently at least some versions of Linux have a 90 !minute!

This can 484738032Speter result in an extra 60 second delay on startup if your system 484838032Speter hostname (as returned by hostname(1)) has no dot and no names 484938032Speter listed in /etc/hosts or your NIS map have a dot. 485038032Speter Check for proper domain name on HELO and EHLO commands per 485138032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 485238032Speter of Michigan Technological University. 485338032Speter Relax chownsafe rules slightly -- old version said that if you 485438032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 485538032Speter if fpathconf returned EINVAL or ENOSYS), assume that 485638032Speter chown is not safe. The new version falls back to whether 485738032Speter you are on a BSD system or not. This is important for 485838032Speter SunOS, which apparently always returns one of those 485938032Speter error codes. This impacts whether you can mail to files 486038032Speter or not. 486138032Speter Syntax errors such as unbalanced parentheses in the configuration 486238032Speter file could be omitted if you had "Oem" prior to the 486338032Speter syntax error in the config file. Change to always print 486438032Speter the error message. It was especially weird because it 486538032Speter would cause a "warning" message to be sent to the Postmaster 486638032Speter for every message sent (but with no transcript). Problem 486738032Speter noted by Gregory Paris of Motorola. 486838032Speter Rewrite collect and putbody to handle full 8-bit data, including 486938032Speter zero bytes. These changes are internally extensive, but 487038032Speter should have minimal impact on external function. 487138032Speter Allow full words for option names -- if the option letter is 487238032Speter (apparently) a space, then take the word following -- e.g., 487338032Speter O MatchGECOS=TRUE 487438032Speter The full list of old and new names is as follows: 487538032Speter 7 SevenBitInput 487638032Speter 8 EightBitMode 487738032Speter A AliasFile 487838032Speter a AliasWait 487938032Speter B BlankSub 488038032Speter b MinFreeBlocks/MaxMessageSize 488138032Speter C CheckpointInterval 488238032Speter c HoldExpensive 488338032Speter D AutoRebuildAliases 488438032Speter d DeliveryMode 488538032Speter E ErrorHeader 488638032Speter e ErrorMode 488738032Speter f SaveFromLine 488838032Speter F TempFileMode 488938032Speter G MatchGECOS 489038032Speter H HelpFile 489138032Speter h MaxHopCount 489238032Speter i IgnoreDots 489338032Speter I ResolverOptions 489438032Speter J ForwardPath 489538032Speter j SendMimeErrors 489638032Speter k ConnectionCacheSize 489738032Speter K ConnectionCacheTimeout 489838032Speter L LogLevel 489938032Speter l UseErrorsTo 490038032Speter m MeToo 490138032Speter n CheckAliases 490238032Speter O DaemonPortOptions 490338032Speter o OldStyleHeaders 490438032Speter P PostmasterCopy 490538032Speter p PrivacyOptions 490638032Speter Q QueueDirectory 490738032Speter q QueueFactor 490838032Speter R DontPruneRoutes 490938032Speter r, T Timeout 491038032Speter S StatusFile 491138032Speter s SuperSafe 491238032Speter t TimeZoneSpec 491338032Speter u DefaultUser 491438032Speter U UserDatabaseSpec 491538032Speter V FallbackMXHost 491638032Speter v Verbose 491738032Speter w TryNullMXList 491838032Speter x QueueLA 491938032Speter X RefuseLA 492038032Speter Y ForkEachJob 492138032Speter y RecipientFactor 492238032Speter z ClassFactor 492338032Speter Z RetryFactor 492438032Speter The old macros that passed information into sendmail have 492538032Speter been changed to options; those correspondences are: 492638032Speter $e SmtpGreetingMessage 492738032Speter $l UnixFromLine 492838032Speter $o OperatorChars 492938032Speter $q (deleted -- not necessary) 493038032Speter To avoid possible problems with an older sendmail, 493138032Speter configuration level 6 is accepted by this version of 493238032Speter sendmail; any config file using the new names should 493338032Speter specify "V6" in the configuration. 493438032Speter Change address parsing to properly note that a phrase before a 493538032Speter colon and a trailing semicolon are essentially the same 493638032Speter as text outside of angle brackets (i.e., sendmail should 493738032Speter treat them as comments). This is to handle the 493838032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 493938032Speter assume that ``group name:'' is a comment on the first 494038032Speter address and the ``;'' is a comment on the last address). 494138032Speter This requires config file support to get right. It does 494238032Speter understand that :: is NOT this syntax, and can be turned 494338032Speter off completely by setting the ColonOkInAddresses option. 494438032Speter Level 6 config files added with new mailer flags: 494538032Speter A Addresses are aliasable. 494638032Speter i Do udb rewriting on envelope as well as header 494738032Speter sender lines. Applies to the from address mailer 494838032Speter flags rather than the recipient mailer flags. 494938032Speter j Do udb rewriting on header recipient addresses. 495038032Speter Applies to the sender mailer flags rather than the 495138032Speter recipient mailer flags. 495238032Speter k Disable check for loops when doing HELO command. 495338032Speter o Always run as the mail recipient, even on local 495438032Speter delivery. 495538032Speter w Check for an /etc/passwd entry for this user. 495638032Speter 5 Pass addresses through ruleset 5. 495738032Speter : Check for :include: on this address. 495838032Speter | Check for |program on this address. 495938032Speter / Check for /file on this address. 496038032Speter @ Look up sender header addresses in the user 496138032Speter database. Applies to the mailer flags for the 496238032Speter mailer corresponding to the envelope sender 496338032Speter address, rather than to recipient mailer flags. 496438032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 496538032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 496638032Speter mailers, and the ColonOkInAddresses option. 496738032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 496838032Speter John Beck of Hewlett-Packard, who generously contributed 496938032Speter their implementation to me, which I then didn't use (see 497038032Speter mime.c for an explanation of why). This adds the 497138032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 497238032Speter to control handling of 8-bit data. These have to cope with 497338032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 497438032Speter 8-bit data that is entered without declaring it as 8-bit 497538032Speter MIME -- technically this is illegal according to the 497638032Speter specs) and labelled 8-bit data (that is, it was declared 497738032Speter as 8BITMIME in the ESMTP session or by using the 497838032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 497943730Speter set then 8-bit data is sent to non-8BITMIME machines 498038032Speter instead of converting to 7 bit (essentially using 498138032Speter just-send-8 semantics). The values for EightBitMode are: 498238032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 498338032Speter any necessary conversion of 8BITMIME to 7BIT 498438032Speter (essentially, the full MIME option). 498538032Speter p pass unlabelled 8-bit input, but convert labelled 498638032Speter 8BITMIME input to 7BIT as required (default). 498738032Speter s strict adherence: reject unlabelled 8-bit input, 498838032Speter convert 8BITMIME to 7BIT as required. The F=8 498938032Speter flag is ignored. 499038032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 499138032Speter the setting of F=8. 499238032Speter Add new internal class 'n', which is the set of MIME Content-Types 499338032Speter which can not be 8 to 7 bit encoded because of other 499438032Speter considerations. Types "multipart/*" and "message/*" are 499538032Speter never directly encoded (although their components can be). 499638032Speter Add new internal class 's', which is the set of subtypes of the 499738032Speter MIME message/* content type that can be treated as though 499838032Speter they are an RFC822 message. It is predefined to have 499938032Speter "rfc822". Suggested By Kari Hurtta. 500038032Speter Add new internal class 'e'. This is the set of MIME 500138032Speter Content-Transfer-Encodings that can be converted to 500238032Speter a seven bit format (Quoted-Printable or Base64). It is 500338032Speter preinitialized to contain "7bit", "8bit", and "binary". 500438032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 500538032Speter short name) to set the default character set to use in the 500638032Speter Content-Type: header when doing encoding of an 8-bit message 500738032Speter which isn't marked as MIME into MIME format. If the C= 500838032Speter parameter is set on the Envelope From address, use that as 500938032Speter the default encoding; else use the DefaultCharSet option. 501038032Speter If neither is set, it defaults to "unknown-8bit" as 501138032Speter suggested by RFC 1428 section 3. 501238032Speter Allow ``U=user:group'' field in mailer definition to set a default 501338032Speter user and group that a mailer will be executed as. This 501438032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 501538032Speter also set, it is the uid/gid that will always be used (that 501638032Speter is, the controlling address is ignored). The values may be 501738032Speter numeric or symbolic; if only a symbolic user is given (no 501838032Speter group) that user's default group in the passwd file is used 501938032Speter as the group. Based on code donated by Chip Rosenthal of 502038032Speter Unicom. 502138032Speter Allow `u' option to also accept user:group as a value, in the same 502238032Speter fashion as the U= mailer option. 502338032Speter Add the symbolic time zone name in the Arpanet format dates (as 502438032Speter a comment). This adds a new compile-time configuration 502538032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 502638032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 502738032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 502838032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 502938032Speter timezone()), or TZ_NONE (don't include the comment). Code 503038032Speter from Chip Rosenthal. 503138032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 503238032Speter For example, 503338032Speter O Timeout.helo = 2m 503438032Speter There are also two new suboptions "queuereturn" and 503538032Speter "queuewarn"; these subsume the old T option. Thus, to 503638032Speter set them both the preferred new syntax is 503738032Speter O Timeout.queuereturn = 5d 503838032Speter O Timeout.queuewarn = 4h 503938032Speter Sort queue by host name instead of by message priority if the 504038032Speter QueueSortOrder option (no short name) is set is set to 504138032Speter ``host''. This makes better use of the connection cache, 504238032Speter but may delay more ``interactive'' messages behind large 504338032Speter backlogs under some circumstances. This is probably a 504438032Speter good option if you have high speed links or don't do lots 504538032Speter of ``batch'' messages, but less good if you are using 504638032Speter something like PPP on a 14.4 modem. Based on code 504738032Speter contributed by Roy Mongiovi of Georgia Tech (my main 504838032Speter contribution was to make it configurable). 504938032Speter Save i-number of df file in qf file to simplify rebuilding of queue 505038032Speter after disastrous disk crash. Suggested by Kyle Jones of 505138032Speter UUNET; closely based on code from KJS DECWRL code written 505238032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 505338032Speter are NOT back compatible with 8.6 -- that is, you can convert 505438032Speter from 8.6 to 8.7, but not the other direction. 505538032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 505638032Speter route-addrs in envelopes; this is because in some cases 505738032Speter they can be sent to the shell, which interprets them as 505838032Speter I/O redirection. 505938032Speter Don't include error file (option E) with return-receipts; this 506038032Speter can be confusing. 506138032Speter Don't send "Warning: cannot send" messages to owner-* or 506238032Speter *-request addresses. Suggested by Christophe Wolfhugel 506338032Speter of the Institut Pasteur, Paris. 506438032Speter Allow -O command line flag to set long form options. 506538032Speter Add "MinQueueAge" option to set the minimum time between attempts 506638032Speter to run the queue. For example, if the queue interval 506738032Speter (-q value) is five minutes, but the minimum queue age 506838032Speter is fifteen minutes, jobs won't be tried more often than 506938032Speter once every fifteen minutes. This can be used to give 507038032Speter you more responsiveness if your delivery mode is set to 507138032Speter queue-only. 507238032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 507338032Speter :include: and .forward files. 507438032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 507538032Speter key field name, the value field name, and the field 507638032Speter delimiter. The field delimiter can be a single character 507738032Speter or the sequence "\t" or "\n" for tab or newline. 507838032Speter These are for use by NIS+ and similar access methods. 507938032Speter Change maps to always strip quotes before lookups; the -q flag 508038032Speter turns off this behavior. Suggested by Motonori Nakamura. 508138032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 508238032Speter key and value field names respectively. Code donated by 508338032Speter Sun Microsystems. 508438032Speter Add "hesiod" map class. The "file name" is used as the 508538032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 508638032Speter first value found for the match. Code donated by Scott 508738032Speter Hutton of Indiana University. 508838032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 508938032Speter specify the name of the property that is searched as the 509038032Speter key and a -v flag to specify the name of the property that 509138032Speter is returned as the value (defaults to "members"). The 509238032Speter default map is "/aliases". Some code based on code 509338032Speter contributed by Robert La Ferla of Hot Software. 509438032Speter Add "text" map class. This does slow, linear searches through 509538032Speter text files. The -z flag specifies a column delimiter 509638032Speter (defaults to any sequence of white space), the -k flag 509738032Speter sets the key column number, and the -v flag sets the 509838032Speter value column number. Lines beginning with `#' are treated 509938032Speter as comments. 510038032Speter Add "program" map class to execute arbitrary programs. The search 510138032Speter key is presented as the last argument; the output is one 510238032Speter line read from the programs standard output. Exit statuses 510338032Speter are from sysexits.h. 510438032Speter Add "sequence" map class -- searches maps in sequence until it 510538032Speter finds a match. For example, the declarations: 510638032Speter Kmap1 ... 510738032Speter Kmap2 ... 510838032Speter Kmapseq sequence map1 map2 510938032Speter defines a map "mapseq" that first searches map1; if the 511038032Speter value is found it is returned immediately, otherwise 511138032Speter map2 is searched and the value returned. 511238032Speter Add "switch" map class. This is much like "sequence" except that 511338032Speter the ordering is fetched from an external file, usually 511438032Speter the system service switch. The parameter is the name of 511538032Speter the service to switch on, and the maps that it will use 511638032Speter are the name of the switch map followed by ".service_type". 511738032Speter For example, if the declaration of the map is 511838032Speter Ksample switch hosts 511938032Speter and the system service switch specifies that hosts are 512038032Speter looked up using dns and nis in that order, then this is 512138032Speter equivalent to 512238032Speter Ksample sequence sample.dns sample.nis 512338032Speter The subordinate maps (sample.*) must already be defined. 512438032Speter Add "user" map class -- looks up users using getpwnam. Takes a 512538032Speter "-v field" flag on the definition that tells what passwd 512638032Speter entry to return -- legal values are name, passwd, uid, gid, 512738032Speter gecos, dir, and shell. Generally expected to be used with 512838032Speter the -m (matchonly) flag. 512938032Speter Add "bestmx" map class -- returns the best MX value for the host 513038032Speter listed as the value. If there are several "best" MX records 513138032Speter for this host, one will be chosen at random. 513238032Speter Add "userdb" map class -- looks up entries in the user database. 513338032Speter The "file name" is actually the tag that will be used, 513438032Speter typically "mailname". If there are multiple entries 513538032Speter matching the name, the one chosen is undefined. 513638032Speter Add multiple queue timeouts (both return and warning). These are 513738032Speter set by the Precedence: or Priority: header fields to one of 513838032Speter three values. If a Priority: is set and has value "normal", 513938032Speter "urgent", or "non-urgent" the corresponding timeouts are 514038032Speter used. If no priority is set, the Precedence: is consulted; 514138032Speter if negative, non-urgent timeouts are used; if greater than 514238032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 514338032Speter are used. The timeouts are set by setting the six timeouts 514443730Speter queue{warn,return}.{urgent,normal,non-urgent}. 514538032Speter Fix problem when a mail address is resolved to a $#error mailer 514638032Speter with a temporary failure indication; it works in SMTP, 514738032Speter but when delivering locally the mail is silently discarded. 514838032Speter This patch, from Kyle Jones of UUNET, bounces it instead 514938032Speter of queueing it (queueing is very hard). 515038032Speter When using /etc/hosts or NIS-style lookups, don't assume that 515138032Speter the first name in the list is the best one -- instead, 515238032Speter search for the first one with a dot. For example, if 515338032Speter an /etc/hosts entry reads 515438032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 515538032Speter this change will use the second name as the canonical 515638032Speter machine name instead of the initial, unqualified name. 515738032Speter Change dequote map to replace spaces in quoted text with a value 515838032Speter indicated by the -s flag on the dequote map definition. 515938032Speter For example, ``Mdequote dequote -s_'' will change 516038032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 516138032Speter quoted (because of the space character). Suggested by Dan 516238032Speter Oscarsson for use in X.400 addresses. 516338032Speter Implement long macro names as ${name}; long class names can 516438032Speter be similarly referenced as $={name} and $~{name}. 516538032Speter Definitions are (e.g.) ``D{name}value''. Names that have 516638032Speter a leading lower case letter or punctuation characters are 516738032Speter reserved for internal use by sendmail; i.e., config files 516838032Speter should use names that begin with a capital letter. Based 516938032Speter on code contributed by Dan Oscarsson. 517038032Speter Fix core dump if getgrgid returns a null group list (as opposed 517138032Speter to an empty group list, that is, a pointer to a list 517238032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 517338032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 517438032Speter failed, it called syserr which called newstr which called 517538032Speter xalloc.... The newstr is now avoided for "panic" messages. 517638032Speter Reported by Stuart Kemp of James Cook University. 517738032Speter Improve connection cache timeouts; previously, they were not even 517838032Speter checked if you were delivering to anything other than an 517938032Speter IPC-connected host, so a series of (say) local mail 518038032Speter deliveries could cause cached connections to be open 518138032Speter much longer than the specified timeout. 518238032Speter If an incoming message exceeds the maximum message size, stop 518338032Speter writing the incoming bytes to the queue data file, since 518438032Speter this can fill your mqueue partition -- this is a possible 518538032Speter denial-of-service attack. 518638032Speter Don't reject all numeric local user names unless HESIOD is 518738032Speter defined. It turns out that Posix allows all-numeric 518838032Speter user names. Fix from Tony Sanders of BSDI. 518938032Speter Add service switch support. If the local OS has a service 519038032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 519138032Speter on DEC systems) that will be used; otherwise, it falls back 519238032Speter to using a local mechanism based on the ServiceSwitchFile 519338032Speter option (default: /etc/service.switch). For example, if the 519438032Speter service switch lists "files" and "nis" for the aliases 519538032Speter service, that will be the default lookup order. the "files" 519638032Speter ("local" on DEC) service type expands to any alias files 519738032Speter you listed in the configuration file, even if they aren't 519838032Speter actually file lookups. 519938032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 520038032Speter variable which tells whether or not DNS should be considered 520138032Speter canonical. This is now determined based on whether or not 520238032Speter "dns" is in the service list for "hosts". 520364562Sgshapiro Add preliminary support for the ESMTP "DSN" extension (Delivery 520438032Speter Status Notifications). DSN notifications override 520538032Speter Return-Receipt-To: headers, which are bogus anyhow -- 520638032Speter support for them has been removed. 520738032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 520838032Speter definitions to define the types used in DSN returns for 520938032Speter MTA names, addresses, and diagnostics respectively. 521038032Speter Extend heuristic to force running in ESMTP mode to look for the 521138032Speter five-character string "ESMTP" anywhere in the 220 greeting 521238032Speter message (not just the second line). This is to provide 521338032Speter better compatibility with other ESMTP servers. 521438032Speter Print sequence number of job when running the queue so you can 521538032Speter easily see how much progress you have made. Suggested 521638032Speter by Peter Wemm of DIALix. 521738032Speter Map newlines to spaces in logged message-ids; some versions of 521838032Speter syslog truncate the rest of the line after newlines. 521938032Speter Suggested by Fletcher Mattox of U. Texas. 522038032Speter Move up forking for job runs so that if a message is split into 522138032Speter multiple envelopes you don't get "fork storms" -- this 522238032Speter also improves the connection cache utilization. 522338032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 522438032Speter the purposes of refusing to send error returns. Suggested 522538032Speter by Motonori Nakamura of Ritsumeikan University. 522638032Speter Relax rules on when a file can be written when referenced from 522738032Speter the aliases file: use the default uid/gid instead of the 522838032Speter real uid/gid. This allows you to create a file owned by 522938032Speter and writable only by the default uid/gid that will work 523038032Speter all the time (without having the setuid bit set). Change 523138032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 523238032Speter Microsystems. 523338032Speter Add "DialDelay" option (no short name) to provide an "extra" 523438032Speter delay for dial on demand systems. If this is non-zero 523538032Speter and a connect fails, sendmail will wait this long and 523638032Speter then try again. If it takes longer than the kernel 523738032Speter timeout interval to establish the connection, this 523838032Speter option can give the network software time to establish 523938032Speter the link. The default units are seconds. 524038032Speter Move logging of sender information to be as early as possible; 524138032Speter previously, it could be delayed a while for SMTP mail 524238032Speter sent to aliases. Suggested by Brad Knowles of the 524338032Speter Defense Information Systems Agency. 524438032Speter Call res_init() before setting RES_DEBUG; this is required by 524538032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 524638032Speter the National Computer Security Center. 524738032Speter Add xdelay= field in logs -- this is a transaction delay, telling 524838032Speter you how long it took to deliver to this address on the 524938032Speter last try. It is intended to be used for sorting mailing 525038032Speter lists to favor "quick" addresses. Provided for use by 525138032Speter the mailprio scripts (see below). 525238032Speter If a map cannot be opened, and that map is non-optional, and 525338032Speter an address requires that map for resolution, queue the 525438032Speter map instead of bouncing it. This involves creating a 525538032Speter pseudo-class of maps called "bogus-map" -- if a required 525638032Speter map cannot be opened, the class is changed to bogus-map; 525738032Speter all queries against bogus-map return "tempfail". The 525838032Speter bogus-map class is not directly accessible. A sample 525938032Speter implementation was donated by Jem Taylor of Glasgow 526038032Speter University Computing Service. 526138032Speter Fix a possible core dump when mailing to a program that talks 526238032Speter SMTP on its standard input. Fix from Keith Moore of 526338032Speter the University of Kentucky. 526438032Speter Make it possible to resolve filenames to $#local $: @ /filename; 526538032Speter previously, the "@" would cause it to not be recognized 526638032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 526738032Speter Accept a -1 signal to re-exec the daemon. This only works if 526838032Speter argv[0] is a full path to sendmail. 526938032Speter Fix bug in "addr=..." field in O option on little-endian machines 527038032Speter -- the network number wasn't being converted to network 527138032Speter byte order. Patch from Kurt Lidl of Pix Technologies 527238032Speter Corporation. 527338032Speter Pre-initialize the resolver early on; this is to avoid a bug with 527438032Speter BIND 4.9.3 that can cause the _res.retry field to get 527538032Speter reset to zero, causing all name server lookups to time 527638032Speter out. Fix from Matt Day of Artisoft. 527738032Speter Restore T line (trusted users) in config file -- but instead of 527838032Speter locking out the -f flag, they just tell whether or not 527938032Speter an X-Authentication-Warning: will be added. This really 528038032Speter just creates new entries in class 't', so "Ft/file/name" 528138032Speter can be used to read trusted user names from a file. 528238032Speter Trusted users are also allowed to execute programs even 528338032Speter if they have a shell that isn't in /etc/shells. 528438032Speter Improve NEWDB alias file rebuilding so it will create them 528538032Speter properly if they do not already exist. This had been 528638032Speter a MAYBENEXTRELEASE feature in 8.6.9. 528738032Speter Check for @:@ entry in NIS maps before starting up to avoid 528838032Speter (but not prevent, sigh) race conditions. This ought to 528938032Speter be handled properly in ypserv, but isn't. Suggested by 529038032Speter Michael Beirne of Motorola. 529138032Speter Refuse connections if there isn't enough space on the filesystem 529238032Speter holding the queue. Contributed by Robert Dana of Wolf 529338032Speter Communications. 529438032Speter Skip checking for directory permissions in the path to a file 529538032Speter when checking for file permissions iff setreuid() 529638032Speter succeeded -- it is unnecessary in that case. This avoids 529738032Speter significant performance problems when looking for .forward 529838032Speter files. Based on a suggestion by Win Bent of USC. 529938032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 530038032Speter arbitrary ruleset number assigned or "Sname = integer" 530138032Speter to assign a specific ruleset number. Reference is 530238032Speter $>name_or_number. Names can be composed of alphas, digits, 530338032Speter underscore, or hyphen (first character must be non-numeric). 530438032Speter Allow -o flag on AliasFile lines to make the alias file optional. 530538032Speter From Bryan Costales of ICSI. 530638032Speter Add NoRecipientAction option to handle the case where there is 530738032Speter no legal recipient header in the message. It can take 530838032Speter on values: 530938032Speter None Leave the message as is. The 531038032Speter message will be passed on even 531138032Speter though it is in technically 531238032Speter illegal syntax. 531338032Speter Add-To Add a To: header with any 531438032Speter recipients that it can find from 531538032Speter the envelope. This risks exposing 531638032Speter Bcc: recipients. 531738032Speter Add-Apparently-To Add an Apparently-To: header. This 531838032Speter has almost no redeeming social value, 531938032Speter and is provided only for back 532038032Speter compatibility. 532138032Speter Add-To-Undisclosed Add a header reading 532238032Speter To: undisclosed-recipients:; 532338032Speter which will have the effect of 532438032Speter making the message legal without 532538032Speter exposing Bcc: recipients. 532638032Speter Add-Bcc To add an empty Bcc: header. 532738032Speter There is a chance that mailers down 532838032Speter the line will delete this header, 532938032Speter which could cause exposure of Bcc: 533038032Speter recipients. 533138032Speter The default is NoRecipientAction=None. 533238032Speter Truncate (rather than delete) Bcc: lines in the header. This 533338032Speter should prevent later sendmails (at least, those that don't 533438032Speter themselves delete Bcc:) from considering this message to 533538032Speter be non-conforming -- although it does imply that non-blind 533638032Speter recipients can see that a Bcc: was sent, albeit not to whom. 533738032Speter Add SafeFileEnvironment option. If declared, files named as delivery 533838032Speter targets must be regular files in addition to the regular 533938032Speter checks. Also, if the option is non-null then it is used as 534038032Speter the name of a directory that is used as a chroot(2) 534138032Speter environment for the delivery; the file names listed in an 534238032Speter alias or forward should include the name of this root. 534338032Speter For example, if you run with 534438032Speter O SafeFileEnvironment=/arch 534538032Speter then aliases should reference "/arch/rest/of/path". If a 534638032Speter value is given, sendmail also won't try to save to 534738032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 534838032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 534938032Speter Support -A flag for alias files; this will comma concatenate like 535038032Speter entries. For example, given the aliases: 535138032Speter list: member1 535238032Speter list: member2 535338032Speter and an alias file declared as: 535438032Speter OAhash:-A /etc/aliases 535538032Speter the final alias inserted will be "list: member1,member2"; 535638032Speter without -A you will get an error on the second and subsequent 535738032Speter alias for "list".

Suggested by Liudvikas Bukys. 535938032Speter Fix a problem that could cause very long addresses to core dump in 536038032Speter some special circumstances. Problem pointed out by Allan 536138032Speter Johannesen. 536238032Speter (Internal change.) Change interface to expand() (macro expansion) 536338032Speter to be simpler and more consistent. 536438032Speter Delete check for funny qf file names. This didn't really give 536538032Speter any extra security and caused some people some problems. 536638032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 536738032Speter at compile time.) Suggested by Kyle Jones of UUNET. 536838032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 536938032Speter merge with DSN code; this is simpler and more consistent. 537038032Speter This may affect some people who have written their own 537138032Speter checkcompat() routine. 537238032Speter (Internal change.) Eliminate `D' line in qf file. The df file 537338032Speter is now assumed to be the same name as the qf file (with 537438032Speter the `q' changed to a `d', of course). 537538032Speter Avoid forking for delivery if all recipient mailers are marked as 537638032Speter "expensive" -- this can be a major cost on some systems. 537738032Speter Essentially, this forces sendmail into "queue only" mode 537838032Speter if all it is going to do is queue anyway. 537938032Speter Avoid sending a null message in some rather unusual circumstances 538038032Speter (specifically, the RCPT command returns a temporary 538138032Speter failure but the connection is lost before the DATA 538238032Speter command). Fix from Scott Hammond of Secure Computing 538338032Speter Corporation. 538438032Speter Change makesendmail to use a somewhat more rational naming scheme: 538538032Speter Makefiles and obj directories are named $os.$rel.$arch, 538638032Speter where $os is the operating system (e.g., SunOS), $rel is 538738032Speter the release number (e.g., 5.3), and $arch is the machine 538838032Speter architecture (e.g., sun4). Any of these can be omitted, 538938032Speter and anything after the first dot in a release number can 539038032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 539138032Speter version used $os.$arch.$rel and was rather less general. 539238032Speter Change makesendmail to do a "make depend" in the target directory 539338032Speter when it is being created. This involves adding an empty 539438032Speter "depend:" entry in most Makefiles. 539538032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 539638032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 539738032Speter of the Finnish Meteorological Institute. 539838032Speter Fix problem that could cause multiple responses to DATA command 539938032Speter on header syntax errors (e.g., lines beginning with colons). 540038032Speter Problem noted by Jens Thomassen of the University of Oslo. 540138032Speter Don't let null bytes in headers cause truncation of the rest of 540238032Speter the header. 540338032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 540438032Speter Increase timeouts on message data puts to allow time for receivers 540538032Speter to canonify addresses in headers on the fly. This is still 540638032Speter a rather ugly heuristic. From Motonori Nakamura. 540738032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 540838032Speter records are not used when canonifying names, and when MX 540938032Speter lookups are done for addressing they must be fully 541038032Speter qualified. This is useful if you have a wildcard MX record, 541138032Speter although it may cause other problems. In general, don't use 541238032Speter wildcard MX records. Patch from Motonori Nakamura. 541338032Speter Eliminate default two-line SMTP greeting message. Instead of 541438032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 541538032Speter is added between the first and second word of the first 541638032Speter line of the greeting message (i.e., immediately after the 541738032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 541838032Speter compile flag. Old sendmails won't see the ESMTP, but that's 541938032Speter acceptable because SIZE was the only useful extension that 542038032Speter old sendmails understand. 542138032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 542238032Speter invoked state dumps. From Masaharu Onishi. 542338032Speter Allow on-line comments in .forward and :include: files; they are 542438032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 542538032Speter is a space or a tab. This is intended for native 542638032Speter representation of non-ASCII sets such as Japanese, where 542738032Speter existing encodings would be unreadable or would lose 542838032Speter data -- for example, 542938032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 543038032Speter (romanized/less information) 543138032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 543238032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 543338032Speter (with MIME encoding, not human readable) 543438032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 543538032Speter (native encoding with ISO-2022-JP) 543638032Speter The last form is human readable in the Japanese environment. 543738032Speter Based on a fix from (surprise!) Motonori Nakamura. 543838032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 543938032Speter messages to that host; these are most frequently associated 544038032Speter with addresses rather than the host, with the exception of 544138032Speter 421 (service shutting down). The effect was to cause queues 544238032Speter to sometimes take an excessive time to flush. Reported by 544338032Speter Robert Sargent of Southern Geographics Technologies and 544438032Speter Eric Prestemon of American University. 544538032Speter Add Nice=N mailer option to set the niceness at which a mailer will 544638032Speter run. This is actually a relative niceness (that is, an 544738032Speter increment on the background value). 544838032Speter Log queue runs that are skipped due to high loads. They are logged 544938032Speter at LOG_INFO priority iff the log level is > 8. Contributed 545038032Speter by Bruce Nagel of Data General. 545138032Speter Allow the error mailer to accept a DSN-style error status code 545238032Speter instead of an sysexits status code in the host part. 545338032Speter Anything with a dot will be interpreted as a DSN-style code. 545438032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 545538032Speter to encode characters that might be munged by an EBCDIC system 545638032Speter in addition to the set required by RFC 1521. The additional 545738032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 545838032Speter (Think of "IBM 360" as the mnemonic for this flag.) 545938032Speter Change check for mailing to files to look for a pathname of [FILE] 546038032Speter rather than looking for the mailer named *file*. The mapping 546138032Speter of leading slashes still goes to the *file* mailer. This 546238032Speter allows you to implement the *file* mailer as a separate 546338032Speter program, for example, to insert a Content-Length: header 546438032Speter or do special security policy. However, note that the usual 546538032Speter initial checking for the file permissions is still done, and 546638032Speter the program in question needs to be very careful about how 546738032Speter it does the file write to avoid security problems. 546838032Speter Be able to read ~root/.forward even if the path isn't accessible to 546938032Speter regular users. This is disrecommended because sendmail 547038032Speter sometimes does not run as root (e.g., when an unsafe option 547138032Speter is specified on the command line), but should otherwise be 547238032Speter safe because .forward files must be owned by the user for 547338032Speter whom mail is being forwarded, and cannot be a symbolic link. 547438032Speter Suggested by Forrest Aldrich of Wang Laboratories. 547538032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 547638032Speter file. This is used for canonifying hostnames when the 547738032Speter service type is "files". 547838032Speter Implement programs on F (read class from file) line. The syntax is 547938032Speter Fc|/path/to/program to read the output from the program 548038032Speter into class "c". 548138032Speter Probe the network interfaces to find alternate names for this 548238032Speter host. Requires the SIOCGIFCONF ioctl call. Code 548338032Speter contributed by SunSoft. 548438032Speter Add "E" configuration line to set or propagate environment 548538032Speter variables into children. "E<envar>" will propagate 548638032Speter the named variable from the environment when sendmail 548738032Speter was invoked into any children it calls; "E<envar>=<value>" 548838032Speter sets the named variable to the indicated value. Any 548938032Speter variables not explicitly named will not be in the child 549038032Speter environment. However, sendmail still forces an 549138032Speter "AGENT=sendmail" environment variable, in part to enforce 549238032Speter at least one environment variable, since many programs and 549338032Speter libraries die horribly if this is not guaranteed. 549438032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 549538032Speter alias databases -- new algorithm looks for the substring 549638032Speter "/yp/" in the file name. This is more portable and involves 549738032Speter less overhead.

The old QUEUESIZE compile parameter 550038032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 550138032Speter should not need to be changed) and the MaxQueueRunSize option, 550238032Speter which is the absolute maximum number of jobs that will ever 550338032Speter be handled in a single queue run. Based on code contributed 550438032Speter by Brian Coan of the Institute for Global Communications. 550538032Speter Log message when a message is dropped because it exceeds the maximum 550638032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 550738032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 550838032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 550938032Speter of Mark G. Thomas Consulting. 551038032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 551138032Speter OS-dependent defines). The old semantic of -d0.1 to not 551238032Speter run the daemon in background has been moved to -d99.100, 551338032Speter and the old 52.5 flag (to avoid disconnect() from closing 551438032Speter all output files) has been moved to 52.100. This makes 551538032Speter things more consistent (flags below .100 don't change 551638032Speter semantics) and separates out the backgrounding so that 551738032Speter it doesn't happen automatically on other unrelated debugging 551838032Speter flags. 551938032Speter If -t is used but no addresses are found in the header, give an 552038032Speter error message rather than just doing nothing. Fix from 552138032Speter Motonori Nakamura. 552238032Speter On systems (like SunOS) where the effective gid is not necessarily 552338032Speter included in the group list returned by getgroups(), the 552438032Speter `restrictmailq' option could sometimes cause an authorized 552538032Speter user to not be able to use `mailq'. Fix from Charles Hannum 552638032Speter of MIT. 552738032Speter Allow symbolic service names for [IPC] mailers. Suggested by 552838032Speter Gerry Magennis of Logica International. 552938032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 553038032Speter when running DNS. For example, if the name FTP.Foo.ORG is 553138032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 553238032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 553338032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 553438032Speter This is technically illegal under RFC 822 and 1123, but the 553538032Speter IETF is moving toward legalizing it. Note that turning on 553638032Speter this option is not sufficient to guarantee that a downstream 553738032Speter neighbor won't rewrite the address for you. 553838032Speter Add "-m" flag to makesendmail script -- this tells you what object 553938032Speter directory and Makefile it will use, but doesn't actually do 554038032Speter the make. 554138032Speter Do some additional checking on the contents of the qf file to try 554238032Speter to detect attacks against the qf file. In particular, 554338032Speter abort on any line beginning "From ", and add an "end of 554438032Speter file" line -- any data after that line is prohibited. 554538032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 554638032Speter choices. This can be overridden in the Makefile by using 554738032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 554838032Speter (to the extent that we know it) or by defining 554938032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 555038032Speter sendmail 8 to have more consistent installation instructions. 555138032Speter Allow macros on `K' line in config file.

Suggested by Motonori Nakamura. 556038032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 556138032Speter of dropping out entirely. This makes testing some of the 556238032Speter name server lookups easier to deal with when there are 556338032Speter hung servers. From Motonori Nakamura. 556438032Speter Add new ${opMode} macro that is set to the current operation mode 556538032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 556638032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 556738032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 556838032Speter Kind of like queue-only mode (Odq) except it tries to avoid 556938032Speter any external service requests; for dial-on-demand hosts that 557038032Speter want to minimize DNS lookups when mail is being queued. For 557138032Speter this to work you will also have to make sure that gethostbyname 557238032Speter of your local host name does not do a DNS lookup. 557338032Speter Improved handling of "out of space" conditions from John Myers of 557438032Speter Carnegie Mellon. 557538032Speter Improved security for mailing to files on systems that have fchmod(2) 557638032Speter support. 557738032Speter Improve "cannot send message for N days" message -- now says "could 557838032Speter not send for past N days".

Patches 559238032Speter from Alexander Dupuy of System Management ARTS. 559338032Speter Delete duplicates in MX lists -- believe it or not, there are sites 559438032Speter that list the same host twice in an MX list. This deletion 559538032Speter only works on adjacent preferences, so an MX list that 559638032Speter had A=5, B=10, A=15 would leave both As, but one that had 559738032Speter A=5, A=10, B=15 would reduce to A, B.

This is intended for forwarding mail 575538032Speter for system aliases such as root and postmaster to a 575638032Speter centralized hub. 575738032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 575838032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 575938032Speter The F=8 flag is also set on the "relay" mailer, since 576038032Speter this is expected to be another sendmail. 576138032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 576238032Speter the name of the UUCP_RELAY -- in some cases, this is the 576338032Speter wrong value (e.g., when we have local UUCP connections), 576438032Speter and this can create unreplyable addresses. From Chip 576538032Speter Rosenthal of Unicom. 576638032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 576738032Speter Received: header inserted into all messages.

From Kimmo Suominen. 578538032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 578638032Speter as the local mailer. For addresses of the form "user+detail" 578738032Speter the "detail" part is passed to procmail via the -a flag. 578838032Speter Contributed by Kimmo Suominen. 578938032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 579038032Speter use from mailertables.

Contributed by Kimmo Suominen. 579238032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 579338032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 579438032Speter Paul Southworth of CICNet Systems Support. 579538032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 579638032Speter This causes the null return path to be rewritten as 579738032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 579838032Speter From Michael Hohmuth of Technische Universitat Dresden. 579938032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 580038032Speter list us as the best possible MX record to be treated as 580138032Speter though they were local (essentially, assume that they 580238032Speter are included in $=w). This can cause additional DNS 580338032Speter traffic, but is easier to administer if this fits your 580438032Speter local model. It does not work reliably if there are 580538032Speter multiple hosts that share the best MX preference. 580638032Speter Code contributed by John Oleynick of Rutgers. 580738032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 580838032Speter SHell) instead of /bin/sh as the program used for delivery 580938032Speter to programs. If an argument is included, it is used as 581038032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 581138032Speter assumed. 581238032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 581338032Speter size of messages to the local and procmail mailers 581438032Speter respectively. Contributed by Brad Knowles of the Defense 581538032Speter Information Systems Agency. 581638032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 581738032Speter (just like text outside of angle brackets) in order to 581838032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 581938032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 582038032Speter any real systems any more) and tweak the DOMAIN macro 582138032Speter so that it is less likely that users will accidentally use 582238032Speter the Berkeley defaults. Also, create some generic files 582338032Speter that really can be used in the real world. 582438032Speter CONFIG: Add new configuration macros to set character sets for 582538032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 582638032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 582738032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 582838032Speter The old name will still be accepted for a while at least. 582938032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 583038032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 583164562Sgshapiro As with all relays, it can be ``mailer:hostname''. Suggested 583238032Speter by Scott Hutton. 583338032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 583443730Speter by Barb Dijker of Labyrinth Computer Services. 583538032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 583638032Speter performance for large alias files, and this confused many 583738032Speter people. 583838032Speter CONFIG: Add confCF_VERSION to append local information to the 583938032Speter configuration version number displayed during SMTP startup. 584038032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 584138032Speter would only work when locally addressed. Fix from 584238032Speter Edvard Tuinder of Cistron Internet Services. 584338032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 584438032Speter "n" (CheckAliases) is set when rebuilding alias database. 584538032Speter Based on code contributed by Claude Marinier. 584638032Speter CONFIG: Allow mailertable to have values of the form 584738032Speter ``error:code message''. The ``code'' is a status code 584838032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 584938032Speter Contributed by David James <dwj@agw.bt.co.uk>. 585038032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 585138032Speter sender domains that will be replaced with the masquerade name. 585238032Speter These domains will not be treated as local, but if mail passes 585338032Speter through with sender addresses in those domains they will be 585438032Speter replaced by the masquerade name. These can also be specified 585538032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 585638032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 585738032Speter as well as the header. Substantial improvements to this 585838032Speter code were contributed by Per Hedeland. 585938032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 586038032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 586138032Speter by Kimmo Suominen. 586238032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 586338032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 586438032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 586538032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 586638032Speter UUCP addressing.

597738032Speter8.6.12/8.6.12 1995/03/28 597838032Speter Fix to IDENT code (it was getting the size of the reply buffer 597938032Speter too small, so nothing was ever accepted). Fix from several 598038032Speter people, including Allan Johannesen, Shane Castle of the 598138032Speter Boulder County Information Services, and Jeff Smith of 598238032Speter Warwick University (all arrived within a few hours of 598338032Speter each other!). 598438032Speter Fix a problem that could cause large jobs to run out of 598538032Speter file descriptors on systems that use vfork() rather 598638032Speter than fork(). 598738032Speter 598838032Speter8.6.11/8.6.11 1995/03/08 598938032Speter The ``possible attack'' message would be logged more often 599038032Speter than necessary if you are using Pine as a user agent. 599138032Speter The wrong host would be reported in the ``possible attack'' 599238032Speter message when attempted from IDENT. 599338032Speter In some cases the syslog buffer could be overflowed when 599438032Speter reporting the ``possible attack'' message. This can 599538032Speter cause denial of service attacks. Truncate the message 599638032Speter to 80 characters to prevent this problem. 599738032Speter When reading the IDENT response a loop is needed around the 599838032Speter read from the network to ensure that you don't get 599938032Speter partial lines. 600038032Speter Password entries without any shell listed (that is, a null 600138032Speter shell) wouldn't match as "ok". Problem noted by 600238032Speter Rob McMahon. 600338032Speter When running BIND 4.9.x a problem could occur because the 600438032Speter _res.options field is initialized differently than it 600538032Speter was historically -- this requires that sendmail call 600638032Speter res_init before it tweaks any bits. 600738032Speter Fix an incompatibility in openxscript() between the file open mode 600838032Speter and the stdio mode passed to fdopen. This caused UnixWare 600938032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 601038032Speter Novell Labs Europe. 601138032Speter Fix problem with static linking of local getopt routine when 601238032Speter using GNU's ld command. Fix from John Kennedy of 601338032Speter Cal State Chico. 601438032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 601738032Speter and Liudvikas Bukys. 601838032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 601938032Speter from Spider Boardman. 602038032Speter CONFIG: No changes (version number only, to keep it in sync 602138032Speter with the binaries). 602238032Speter 602338032Speter8.6.10/8.6.10 1995/02/10 602438032Speter SECURITY: Diagnose bogus values to some command line flags that 602538032Speter could allow trash to get into headers and qf files. 602638032Speter Validate the name of the user returned by the IDENT protocol. 602738032Speter Some systems that really dislike IDENT send intentionally 602838032Speter bogus information. Problem pointed out by Michael Bushnell 602938032Speter of the Free Software Foundation. Has some security 603038032Speter implications. 603138032Speter Fix a problem causing error messages about DNS problems when 603238032Speter the host name contained a percent sign to act oddly 603338032Speter because it was passed as a printf-style format string. 603464562Sgshapiro In some cases this could cause core dumps. 603538032Speter Avoid possible buffer overrun in returntosender() if error 603638032Speter message is quite long. From Fletcher Mattox of the 603738032Speter University of Texas. 603838032Speter Fix a problem that would silently drop "too many hops" error 603938032Speter messages if and only if you were sending to an alias. 604038032Speter From Jon Giltner of the University of Colorado and 604164562Sgshapiro Dan Harton of Oak Ridge National Laboratory. 604238032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 604338032Speter set and e->e_message was null. Fix from Bruce Nagel of 604438032Speter Data General. 604538032Speter Fix problem that can still cause df files to be left around 604638032Speter after "hop count exceeded" messages. Fix from Andrew 604738032Speter Chang and Shau-Ping Lo of SunSoft. 604838032Speter Fix a problem that can cause buffer overflows on very long 604938032Speter user names (as might occur if you piped to a program 605038032Speter with a lot of arguments). 605138032Speter Avoid returning an error and re-queueing if the host signature 605264562Sgshapiro is null; this can occur on addresses like ``user@.''. 605338032Speter Problem noted by Wesley Craig and the University of 605438032Speter Michigan. 605538032Speter Avoid possible calls to malloc(0) if MCI caching is turned 605638032Speter off. Bug fix from Pierre David of the Laboratoire 605738032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 605838032Speter Universite de Versailles - St Quentin, and Jacky 605938032Speter Thibault. 606038032Speter Make a local copy of the line being sent via senttolist() -- in 606138032Speter some cases, buffers could get trashed by map lookups 606238032Speter causing it to do unexpected things. This also simplifies 606338032Speter some of the map code. 606438032Speter CONFIG: No changes (version number only, to keep it in sync 606538032Speter with the binaries). 606638032Speter 606738032Speter8.6.9/8.6.9 1994/04/19 606838032Speter Do all mail delivery completely disconnected from any terminal. 606938032Speter This provides consistency with daemon delivery and 607038032Speter may have some security implications. 607138032Speter Make sure that malloc doesn't get called with zero size, 607238032Speter since that fails on some systems. Reported by Ed 607338032Speter Hill of the University of Iowa. 607438032Speter Fix multi-line values for $e (SMTP greeting message). Reported 607538032Speter by Mike O'Connor of Ford Motor Company. 607638032Speter Avoid syserr if no NIS domain name is defined, but the map it 607738032Speter is trying to open is optional. From Win Bent of USC. 607838032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 607938032Speter Hesiod support for UDB from Todd Miller of the University of 608038032Speter Colorado. Use "hesiod" as the service name in the U 608138032Speter option. 608238032Speter Fix a problem that failed to set the "authentic" host name (that 608338032Speter is, the one derived from the socket info) if you called 608438032Speter sendmail -bs from inetd. Based on code contributed by 608538032Speter Todd Miller (this problem was also reported by Guy Helmer 608638032Speter of Dakota State University). This also fixes a related 608764562Sgshapiro problem reported by Liudvikas Bukys of the University of 608838032Speter Rochester. 608938032Speter Parameterize "nroff -h" in all the Makefiles so people with 609038032Speter variant versions can use them easily. Suggested by 609138032Speter Peter Collinson of Hillside Systems. 609238032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 609338032Speter spaces between parameters instead of one. Reported by 609438032Speter Valdis Kletnieks of Virginia Tech. 609538032Speter Reduce the number of system calls during message collection by 609638032Speter using global timeouts around the collect() loop. This 609738032Speter code was contributed by Eric Wassenaar. 609838032Speter If the initial hostname name gathering results in a name 609938032Speter without a dot (usually caused by NIS misconfiguration) 610038032Speter and BIND is compiled in, directly access DNS to get 610138032Speter the canonical name. This should make life easier for 610238032Speter Solaris systems. If it still can't be resolved, and 610338032Speter if the name server is listed as "required", try again 610438032Speter in 30 seconds. If that also fails, exit immediately to 610538032Speter avoid bogus "config error: mail loops back to myself" 610638032Speter messages. 610738032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 610838032Speter message to explain how much space was available and 610938032Speter sound a bit less threatening. Suggested by Stan Janet 611038032Speter of the National Institute of Standards and Technology. 611138032Speter If mail is delivered to an alias that has an owner, deliver any 611238032Speter requested return-receipt immediately, and strip the 611338032Speter Return-Receipt-To: header from the subsequent message. 611438032Speter This prevents a certain class of denial of service 611538032Speter attack, arguably gives more reasonable semantics, and 611638032Speter moves things more towards what will probably become a 611738032Speter network standard. Suggested by Christopher Davis of 611838032Speter Kapor Enterprises. 611938032Speter Add a "noreceipts" privacy flag to turn off all return receipts 612038032Speter without recompiling. 612138032Speter Avoid printing ESMTP parameters as part of the error message 612238032Speter if there are errors during parsing. This change is 612338032Speter purely cosmetic. 612438032Speter Avoid sending out error messages during the collect phase of 612538032Speter SMTP; there is an MVS mailer from UCLA that gets 612638032Speter confused by this. Of course, I think it's their bug.... 612738032Speter Check for the $j macro getting undefined, losing a dot, or getting 612838032Speter lost from $=w in the daemon before accepting a connection; 612938032Speter if it is, it dumps state, prints a LOG_ALERT message, 613038032Speter and drops core for debugging. This is an attempt to 613164562Sgshapiro track down a bug that I thought was long since gone. 613238032Speter If you see this, please forward the log fragment to 613338032Speter sendmail@sendmail.ORG. 613438032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 613538032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 613638032Speter Wolfhugel. 613738032Speter Instead of trying to truncate the listen queue for the server 613838032Speter SMTP port when the load average is too high, just close 613938032Speter the port completely and reopen it later as needed. 614038032Speter This ensures that the other end gets a quick "connection 614138032Speter refused" response, and that the connection can be 614238032Speter recovered later. In particular, some socket emulations 614338032Speter seem to get confused if you tweak the listen queue 614438032Speter size around and can never start listening to connections 614538032Speter again. The down side is that someone could start up 614638032Speter another daemon process in the interim, so you could 614738032Speter have multiple daemons all not listening to connections; 614838032Speter this could in turn cause the sendmail.pid file to be 614938032Speter incorrect. A better approach might be to accept the 615038032Speter connection and give a 421 code, but that could break 615138032Speter other mailers in mysterious ways and have paging behavior 615238032Speter implications. 615338032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 615438032Speter set debugging on the wrong socket. From Eric Wassenaar. 615538032Speter When creating a df* temporary file, be sure you truncate any 615638032Speter existing data in the file -- otherwise system crashes 615738032Speter and the like could result in extra data being sent. 615838032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 615938032Speter doc directory. This includes some additional 616038032Speter information. 616138032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 616238032Speter of recipient envelope addresses. This should have been 616338032Speter handled by the $&h trick, but broke if people were 616438032Speter mixing domainized and UUCP addresses. They should 616538032Speter probably have converted all the way over to uucp-uudom 616638032Speter instead of uucp-{new,old}, but the failure mode was to 616738032Speter loop the mail, which was bad news. 616838032Speter Portability fixes: 616938032Speter Newer BSDI systems (several people). 617038032Speter Older BSDI systems from Christophe Wolfhugel. 617138032Speter Intergraph CLIX, from Paul Southworth of CICNet. 617238032Speter UnixWare, from Evan Champion. 617338032Speter NetBSD from Adam Glass. 617438032Speter Solaris from Quentin Campbell of the University of 617538032Speter Newcastle upon Tyne. 617638032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 617738032Speter Corporation. 617838032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 617938032Speter SunOS (it has setsid() and setvbuf() calls) from 618038032Speter Jonathan Kamens of OpenVision Technologies. 618138032Speter HP-UX from Tor Lillqvist. 618238032Speter New Files: 618338032Speter src/Makefile.CLIX 618438032Speter src/Makefile.NCR3000 618538032Speter doc/changes/Makefile 618638032Speter doc/changes/changes.me 618738032Speter doc/changes/changes.ps 618838032Speter 618938032Speter8.6.8/8.6.6 1994/03/21 619038032Speter SECURITY: it was possible to read any file as root using the 619138032Speter E (error message) option. Reported by Richard Jones; 619238032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 619338032Speter 619438032Speter8.6.7/8.6.6 1994/03/14 619538032Speter SECURITY: it was possible to get root access by using weird 619638032Speter values to the -d flag. Thanks to Alain Durand of 619738032Speter INRIA for forwarding me the notice from the bugtraq 619838032Speter list. 619938032Speter 620038032Speter8.6.6/8.6.6 1994/03/13 620138032Speter SECURITY: the ability to give files away on System V-based 620238032Speter systems proved dangerous -- don't run as the owner 620338032Speter of a :include: file on a system that allows giveaways. 620438032Speter Unfortunately, this also applies to determining a 620538032Speter valid shell. 620638032Speter IMPORTANT: Previous versions weren't expiring old connections 620738032Speter in the connection cache for a long time under some 620838032Speter circumstances. This could result in resource exhaustion, 620938032Speter both at your end and at the other end. This checks the 621038032Speter connections for timeouts much more frequently. From 621138032Speter Doug Anderson of NCSC. 621238032Speter Fix a glitch that snuck in that caused programs to be run as 621338032Speter the sender instead of the recipient if the mail was 621438032Speter from a local user to another local user. From 621543730Speter Motonori Nakamura of Kyoto University. 621638032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 621738032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 621838032Speter Bryan Costales of ICSI. 621938032Speter Change the method used to declare the "statfs" availability; 622038032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 622138032Speter tweaking in conf.c, there is a single #define called 622238032Speter SFS_TYPE which takes on one of six values (SFS_NONE 622338032Speter for no statfs availability, SFS_USTAT for the ustat(2) 622438032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 622538032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 622638032Speter statfs(2) call with the declarations in <sys/vfs.h>, 622738032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 622838032Speter Fix glitch in NetInfo support that could return garbage if 622938032Speter there was no "/locations/sendmail" property. From 623038032Speter David Meyer of the University of Virginia. 623138032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 623238032Speter to allow Linux to turn it off even though it is a 623338032Speter BSD-like system. 623438032Speter Allow setting of "ident" timeout to zero to turn off the ident 623538032Speter protocol entirely. 623638032Speter Make 7-bit stripping local to a connection (instead of to a 623738032Speter mailer); this allows you to specify that SMTP is a 623838032Speter 7-bit channel, but revert to 8-bit should it advertise 623938032Speter that it supports 8BITMIME. You still have to specify 624038032Speter mailer flag 7 to get this stripping at all. 624138032Speter Improve makesendmail script so it handles more cases automatically. 624238032Speter Tighten up restrictions on taking ownership of :include: files 624338032Speter to avoid problems on systems that allow you to give away 624438032Speter files. 624538032Speter Fix a problem that made it impossible to rebuild the alias 624638032Speter file if it was on a read-only file system. From 624738032Speter Harry Edmon of the University of Washington. 624838032Speter Improve MX randomization function. From John Gardiner Myers 624938032Speter of CMU. 625038032Speter Fix a minor glitch causing a bogus message to be printed (used 625138032Speter %s instead of %d in a printf string for the line number) 625238032Speter when a bad queue file was read. From Harry Edmon. 625364562Sgshapiro Allow $s to remain NULL on locally generated mail. I'm not 625438032Speter sure this is necessary, but a lot of people have complained 625538032Speter about it, and there is a legitimate question as to whether 625638032Speter "localhost" is legal as an 822-style domain. 625738032Speter Fix a problem with very short line lengths (mailer L= flag) in 625864562Sgshapiro headers. This causes a leading space to be added onto 625938032Speter continuation lines (including in the body!), and also 626038032Speter tries to wrap headers containing addresses (From:, To:, 626138032Speter etc) intelligently at the shorter line lengths. Problem 626238032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 626338032Speter Log the real user name when logging syserrs, since these can have 626464562Sgshapiro security implications. Suggested by several people. 626538032Speter Fix address logging of cached connections -- it used to always 626638032Speter log the numeric address as zero. This is a somewhat 626738032Speter bogus implementation in that it does an extra system 626838032Speter call, but it should be an inexpensive one. Fix from 626938032Speter Motonori Nakamura. 627038032Speter Tighten up handling of short syslog buffers even more -- there 627138032Speter were cases where the outgoing relay= name was too long 627238032Speter to share a line with delay= and mailer= logging. 627338032Speter Limit the overhead on split envelopes to one open file descriptor 627438032Speter per envelope -- previously the overhead was three 627538032Speter descriptors. This was in response to a problem reported 627638032Speter by P{r (Pell) Emanuelsson. 627738032Speter Fixes to better handle the case of unexpected connection closes; 627838032Speter this redirects the output to the transcript so the info 627938032Speter is not lost. From Eric Wassenaar. 628038032Speter Fix potential string overrun if you macro evaluate a string that 628138032Speter has a naked $ at the end. Problem noted by James Matheson 628238032Speter <jmrm@eng.cam.ac.uk>. 628338032Speter Make default error number on $#error messages 553 (``Requested 628438032Speter action not taken: mailbox name not allowed'') instead of 628538032Speter 501 (``Syntax error in parameters or arguments'') to 628638032Speter avoid bogus "protocol error" messages. 628738032Speter Strip off any existing trailing dot on names during $[ ... $] 628838032Speter lookup. This prevents it from ending up with two dots 628938032Speter on the end of dot terminated names. From Wesley Craig 629038032Speter of the University of Michigan and Bryan Costales of ICSI. 629138032Speter Clean up file class reading so that the debugging information is 629238032Speter more informative. It hadn't been using setclass, so you 629338032Speter didn't see the class items being added. 629438032Speter Avoid core dump if you are running a version of sendmail where 629538032Speter NIS is compiled in, and you specify an NIS map, but 629638032Speter NIS is not running. Fix from John Oleynick of 629738032Speter Rutgers. 629838032Speter Diagnose bizarre case where res_search returns a failure value, 629938032Speter but sets h_errno to a success value. 630038032Speter Make sure that "too many hops" messages are considered important 630138032Speter enough to send an error to the Postmaster (that is, the 630238032Speter address specified in the P option). This fix should 630338032Speter help problems that cause the df file to be left around 630438032Speter sometimes -- unfortunately, I can't seem to reproduce 630538032Speter the problem myself. 630638032Speter Avoid core dump (null pointer reference) on EXPN command; this 630738032Speter only occurred if your log level was set to 10 or higher 630838032Speter and the target account was an alias or had a .forward file. 630938032Speter Problem noted by Janne Himanka. 631038032Speter Avoid "denial of service" attacks by someone who is flooding your 631138032Speter SMTP port with bad commands by shutting the connection 631238032Speter after 25 bad commands are issued. From Kyle Jones of 631338032Speter UUNET. 631438032Speter Fix core dump on error messages with very long "to" buffers; 631538032Speter fmtmsg overflows the message buffer. Fixed by trimming 631638032Speter the to address to 203 characters. Problem reported by 631738032Speter John Oleynick. 631838032Speter Fix configuration for HASFLOCK -- there were some spots where 631938032Speter a #ifndef was incorrectly #ifdef. Pointed out by 632038032Speter George Baltz of the University of Maryland. 632138032Speter Fix a typo in savemail() that could cause the error message To: 632238032Speter lists to be incorrect in some places. From Motonori 632338032Speter Nakamura. 632438032Speter Fix a glitch that can cause duplicate error messages on split 632538032Speter envelopes where an address on one of the lists has a 632638032Speter name server failure. Fix from Voradesh Yenbut of the 632738032Speter University of Washington. 632838032Speter Fix possible bogus pointer reference on ESMTP parameters that 632938032Speter don't have an ``=value'' part. 633038032Speter CNAME loops caused an error message to be generated, but also 633138032Speter re-queued the message. Changed to just re-queue the 633238032Speter message (it's really hard to just bounce it because 633338032Speter of the weird way the name server works in the presence 633438032Speter of CNAME loops). Problem noted by James M.R.Matheson 633538032Speter of Cambridge University. 633638032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 633738032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 633838032Speter user name. Suggested by Andreas Stolcke of ICSI. 633938032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 634038032Speter override it easily in the Makefile -- that is, you can 634138032Speter turn it off using -DNAMED_BIND=0. 634238032Speter If a gethostbyname(...) of an address with a trailing dot fails, 634338032Speter try it without the trailing dot. This is because if 634438032Speter you have a version of gethostbyname() that falls back 634538032Speter to NIS or the /etc/hosts file it will fail to find 634638032Speter perfectly reasonable names that just don't happen to 634738032Speter be dot terminated in the hosts file. You don't want to 634838032Speter strip the dot first though because we're trying to ensure 634938032Speter that country names that match one of your subdomains get 635038032Speter a chance. 635138032Speter PRALIASES: fix bogus output on non-null-terminated strings. 635238032Speter From Bill Gianopoulos of Raytheon. 635338032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 635438032Speter This was in code intended to only catch the self-literal 635538032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 635638032Speter IP address), but the code was broken. However, it will 635738032Speter still do this if $M is defined; this is necessary to 635838032Speter get client configurations to work (sigh). Note that this 635938032Speter means that $M overrides :mailname entries in the user 636038032Speter database! Problem noted by Paul Southworth. 636138032Speter CONFIG: Fix definition of Solaris help file location. From 636238032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 636338032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 636438032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 636538032Speter and USENET_MAILER_MAX to tweak the maximum message 636638032Speter size for various mailers. 636738032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 636838032Speter instead of assuming that it is "inews" for consistency 636938032Speter with other mailers. From Michael Corrigan of UC San Diego. 637038032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 637138032Speter qualify the address in the SMTP envelope as user@{relay|hub} 637238032Speter instead of user@$j. From Bill Wisner of The Well. 637338032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 637438032Speter CONFIG: Don't turn off case mapping of user names in the local 637538032Speter mailer for IRIX. This was different than most every other 637638032Speter system. 637738032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 637838032Speter envelope. Noted by Thierry Besancon 637938032Speter <besancon@excalibur.ens.fr>. 638038032Speter CONFIG: Don't include -z by default on uux line -- most systems 638138032Speter don't want it set by default. Pointed out by Philippe 638238032Speter Michel of Thomson CSF. 638338032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 638438032Speter host name was foo.bar.ray.com and you matched against 638538032Speter ".ray.com", the old implementation bound %1 to "bar" 638638032Speter instead of "foo.bar". Also, allow "." in the mailertable 638738032Speter to match anything -- essentially, take over SMART_HOST. 638838032Speter This also moves matching of explicit local host names 638938032Speter before the mailertable so they don't have to be special 639038032Speter cased in the mailertable data. Reported by Bill 639138032Speter Gianopoulos of Raytheon; the fix for the %1 binding 639238032Speter problem was contributed by Nicholas Comanos of the 639338032Speter University of Sydney. 639438032Speter CONFIG: Don't include "root" in class $=L (users to deliver 639538032Speter locally, even if a hub or relay exists) by default. 639638032Speter This is because of the known bug where definition of 639738032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 639838032Speter both and deliver into the local mailbox. 639938032Speter CONFIG: Move up bitdomain and uudomain handling so that they 640038032Speter are done before .UUCP class matching; uudomain was 640138032Speter reported as ineffective before. This also frees up 640238032Speter diversion 8 for future use. Problem reported by Kimmo 640338032Speter Suominen. 640438032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 640538032Speter into host names. As pointed out by Jonathan Kamens, 640638032Speter these are often used because either the forward or reverse 640738032Speter mapping is broken; this translation makes it broken again. 640838032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 640938032Speter Suominen. 641038032Speter Portability fixes: 641138032Speter Unicos from David L. Kensiski of Sterling Software. 641238032Speter DomainOS from Don Lewis of Silicon Systems. 641338032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 641438032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 641538032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 641638032Speter BSD/386 from Tony Sanders of BSDI. 641738032Speter Apollo from Eric Wassenaar. 641838032Speter DGUX from Doug Anderson. 641938032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 642038032Speter NEW FILES: 642138032Speter src/Makefile.DomainOS 642238032Speter src/Makefile.PTX 642338032Speter src/Makefile.SunOS.5.1 642438032Speter src/Makefile.SunOS.5.2 642538032Speter src/Makefile.SunOS.5.x 642638032Speter src/mailq.1 642738032Speter cf/ostype/domainos.m4 642838032Speter doc/op/Makefile 642938032Speter doc/intro/Makefile 643038032Speter doc/usenix/Makefile 643138032Speter 643238032Speter8.6.5/8.6.5 1994/01/13 643338032Speter Security fix: /.forward could be owned by anyone (the test 643438032Speter to allow root to own any file was backwards). From 643538032Speter Bob Campbell at U.C. Berkeley. 643638032Speter Security fix: group ids were not completely set when programs 643738032Speter were invoked. This caused programs to have group 643838032Speter permissions they should not have had (usually group 643938032Speter daemon instead of their own group). In particular, 644038032Speter Perl scripts would refuse to run. 644138032Speter Security: check to make sure files that are written are not 644238032Speter symbolic links (at least under some circumstances). 644338032Speter Although this does not respond to a specific known 644438032Speter attack, it's just a good idea. Suggested by 644538032Speter Christian Wettergren. 644638032Speter Security fix: if a user had an NFS mounted home directory on 644738032Speter a system with a restricted shell listed in their 644838032Speter /etc/passwd entry, they could still execute any 644938032Speter program by putting that in their .forward file. 645038032Speter This fix prevents that by insisting that their shell 645138032Speter appear in /etc/shells before allowing a .forward to 645238032Speter execute a program or write a file. You can disable 645338032Speter this by putting "*" in /etc/shells. It also won't 645438032Speter permit world-writable :include: files to reference 645538032Speter programs or files (there's no way to disable this). 645638032Speter These behaviors are only one level deep -- for 645738032Speter example, it is legal for a world-writable :include: 645838032Speter file to reference an alias that writes a file, on 645938032Speter the assumption that the alias file is well controlled. 646038032Speter Security fix: root was not treated suspiciously enough when 646138032Speter looking into subdirectories. This would potentially 646238032Speter allow a cracker to examine files that were publicly 646338032Speter readable but in a non-publicly searchable directory. 646438032Speter Fix a problem that causes an error on QUIT on a cached 646538032Speter connection to create problems on the current job. 646638032Speter These are typically unrelated, so errors occur in 646738032Speter the wrong place. 646838032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 646938032Speter runs more responsive to load average, and fixes a 647038032Speter problem that ignored the load average in locally 647138032Speter generated mail. From Eric Wassenaar. 647238032Speter Fix possible core dump on aliases with null LHS. From 647338032Speter John Orthoefer of BB&N. 647438032Speter Revert to using flock() whenever possible -- there are just 647538032Speter too many bugs in fcntl() locking, particularly over 647638032Speter NFS, that cause sendmail to fail in perverse ways. 647738032Speter Fix a bug that causes the connection cache to get confused 647838032Speter when sending error messages. This resulted in 647938032Speter "unexpected close" messages. It should fix itself 648038032Speter on the following queue run. Problem noted by 648138032Speter Liudvikas Bukys of the University of Rochester. 648238032Speter Include $k in $=k as documented in the Install & Op Guide. 648338032Speter This seems odd, but it was documented.... From 648438032Speter Michael Corrigan of UCSD. 648538032Speter Fix problem that caused :include:s from alias files to be 648638032Speter forced to be owned by root instead of daemon 648738032Speter (actually DefUid). From Tim Irvin. 648838032Speter Diagnose unrecognized I option values -- from Mortin Forssen 648938032Speter of the Chalmers University of Technology. 649038032Speter Make "error" mailer work consistently when there is no error 649138032Speter code associated with it -- previously it returned OK 649238032Speter even though there was a real problem. Now it assumes 649338032Speter EX_UNAVAILABLE. 649438032Speter Fix bug that caused the last header line of messages that had 649538032Speter no body and which were terminated with EOF instead of 649664562Sgshapiro "." to be discarded. Problem noted by Liudvikas Bukys. 649738032Speter Fix core dump on SMTP mail to programs that failed -- it tried 649838032Speter to go to a "next MX host" when none existed, causing 649938032Speter a core dump. From der Mouse at McGill University. 650038032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 650138032Speter this makes it easier to turn it off (using 650238032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 650338032Speter Fix YP_MASTER_NAME store to use the unupdated result of 650438032Speter gethostname() (instead of myhostname(), which tries 650538032Speter to fully qualify the name) to be consistent with 650638032Speter SunOS. If your hostname is unqualified, this fixes 650738032Speter transfers to slave servers. Bug noted by Keith 650838032Speter McMillan of Ameritech Services, Inc. 650938032Speter Fix Ultrix problem: gethostbyname() can return a very large 651038032Speter (> 500) h_length field, which causes the sockaddr 651138032Speter to be trashed. Use the size of the sockaddr instead. 651238032Speter Fix from Bob Manson of Ohio State. 651338032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 651438032Speter defined -- this confuses gethostbyname on hosts 651538032Speter file lookups, which doesn't understand the trailing 651638032Speter dot convention. 651738032Speter Log SMTP server subprocesses that die with a signal instead 651838032Speter of from a clean exit. 651938032Speter If you don't have option "I" set, don't assume that a DNS 652043730Speter "host unknown" message is authoritative -- it 652138032Speter might still be found in /etc/hosts. 652238032Speter Fix a problem that would cause Deferred: messages to be sent 652338032Speter as the subject of an error message, even though the 652438032Speter actual cause of a message was more severe than that. 652538032Speter Problem noted by Chris Seabrook of OSSI. 652638032Speter Fix race condition in DBM alias file locking. From Kyle 652738032Speter Jones of UUNET. 652838032Speter Limit delivery syslog line length to avoid bugs in some 652938032Speter versions of syslog(3). This adds a new compile time 653038032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 653138032Speter University, which is in turn derived from IDA. 653238032Speter Fix quotes inside of comments in addresses -- previously 653338032Speter it insisted that they be balanced, but the 822 spec 653438032Speter says that they should be ignored. 653538032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 653638032Speter debugging). This also evaluates ruleset 89, if set 653738032Speter (with the null input), and logs the result. This 653838032Speter should be used sparingly, since the rewrite process 653938032Speter is not reentrant. 654038032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 654138032Speter documented in the Bat Book. 654238032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 654338032Speter return an error message and did not requeue the message. 654438032Speter Fix based on code from Roland Dirlewanger of 654538032Speter Reseau Regional Aquarel, Bordeaux, France. 654638032Speter Fix a problem that caused a seg fault if you got a 421 error 654738032Speter code during some parts of connection initialization. 654838032Speter I've only seen this when talking to buggy mailers on 654938032Speter the other end, but it shouldn't give a seg fault in 655038032Speter any case. From Amir Plivatsky. 655138032Speter Fix core dump caused by a ruleset call that returns null. 655238032Speter Fix from Bryan Costales of ICSI. 655338032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 655438032Speter of Kyoto University. 655538032Speter Fix a possible problem with very long input lines in setproctitle. 655638032Speter From P{r Emanuelsson. 655738032Speter Avoid putting "This is a warning message" out on return receipts. 655838032Speter Suggested by Douglas Anderson. 655938032Speter Detect loops caused by recursive ruleset calls. Suggested by 656038032Speter Bryan Costales. 656138032Speter Initialize non-alias maps during alias rebuilds -- they may be 656238032Speter needed for parsing. Problem noted by Douglas Anderson. 656338032Speter Log sender address even if no message was collected in SMTP 656438032Speter (e.g., if all RCPTs failed). Suggested by Motonori 656538032Speter Nakamura. 656638032Speter Don't reflect the owner-list contents into the envelope sender 656738032Speter address if the value contains ", :, /, or | (to avoid 656838032Speter illegal addresses appearing there). 656938032Speter Efficiency hack for toktype macro -- from Craig Partridge of 657038032Speter BB&N. 657138032Speter Clean up DNS error printing so that a host name is always 657238032Speter included. 657338032Speter Remember to set $i during queue runs. Reported by Stephen 657438032Speter Campbell of Dartmouth University. 657538032Speter If the environment variable HOSTALIASES is set, use it during 657638032Speter canonification as the name of a file with per-user host 657738032Speter translations so that headers are properly mapped. Reported 657838032Speter by Anne Bennett of Concordia University. 657938032Speter Avoid printing misleading error message if SMTP mailer (not 658038032Speter using [IPC]) should die on a core dump. 658138032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 658238032Speter by the other end closing the connection. From 658338032Speter Dave Morrison of Oracle. 658438032Speter Improve several of the error messages printed by "mailq" 658538032Speter to include a host name or other useful information. 658638032Speter Add NetInfo preliminary support for NeXT systems. From Vince 658738032Speter DeMarco. 658838032Speter Fix a glitch that sometimes caused :include:s that pointed to 658938032Speter NFS filesystems that were down to give an "aliasing/ 659038032Speter forwarding loop broken" message instead of queueing 659138032Speter the message for retry. Noted by William C Fenner of 659238032Speter the NRL Connection Machine Facility. 659338032Speter Fix a problem that could cause a core dump if the input sequence 659438032Speter had (or somehow acquired) a \231 character. 659538032Speter Make sure that route-addrs always have <angle brackets> around 659638032Speter them in non-SMTP envelopes (SMTP envelopes already do 659738032Speter this properly). 659838032Speter Avoid weird headers on unbalanced punctuation of the form: 659938032Speter ``Joe User <user)'' -- this caused reference to the 660038032Speter null macro. Fix from Rick McCarty of IO.COM. 660138032Speter Fix a problem that caused an alias "user: user@local.host" to 660238032Speter not have the QNOTREMOTE bit set; this caused configs 660338032Speter to act as if FEATURE(notsticky) was defined even when 660438032Speter it was not. The effect of the problem was to make it 660538032Speter very hard to to set up satellite sites that had a few 660638032Speter local accounts, with everything else forwarded to a 660738032Speter corporate hub. Reported by Detlef Drewanz of the 660838032Speter University of Rostock and Mark Frost of NCD. 660938032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 661038032Speter addresses. This is more efficient (fewer name server 661138032Speter calls) and fixes certain unusual configurations, such 661238032Speter as those that have ruleset 4 do something that is 661338032Speter non-idempotent unless a mailer-specific ruleset did 661438032Speter something else. Problem reported by Brian J. Coan 661538032Speter of the Institute for Global Communications. 661638032Speter Fix the "obsolete argument" routine in main to better understand 661738032Speter new arguments. For example, if you used ``sendmail 661838032Speter -C config -v -q'' it would choke on the -q because 661938032Speter the -C would stop looking for old-format arguments. 662038032Speter Fix the code that was intended to allow two users to forward their 662138032Speter mail to the same program and have them appear unique. 662238032Speter Portability fixes for: 662338032Speter SCO UNIX from Murray Kucherawy. 662438032Speter SCO Open Server 3.2v4 from Philippe Brand. 662538032Speter System V Release 4 from Rick Ellis and others. 662638032Speter OSF/1 from Steve Campbell. 662738032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 662838032Speter of Stoner Associates. 662938032Speter Motorola SysV88 from Kevin Johnson of Motorola. 663038032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 664438032Speter of the config file has moved to /usr/lib 664538032Speter to match the HP-UX version of sendmail. 664638032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 664738032Speter since this is intended only for internal use, the 664838032Speter usual RFC 821/822/1123 rules can be relaxed. The 664938032Speter main point of this is to avoid munging (ugh) UUCP 665038032Speter addresses when relaying internally. 665138032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 665238032Speter syntax addresses delivered via UUCP. Solution 665338032Speter provided by Peter Wemm. 665438032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 665538032Speter zero; it caused double @ signs in addresses. From 665638032Speter Irving Reid of the University of Toronto. 665738032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 665838032Speter from Markku Toijala of ICL Personal Systems Oy. 665938032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 666038032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 666138032Speter that made it hard to recognize your own pseudodomain 666238032Speter names. 666338032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 666438032Speter rather than letting them get "local configuration 666538032Speter error"s. Problem noted by John Gardiner Myers. 666638032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 666738032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 666838032Speter has uucp-dom semantics but old UUCP syntax. This 666938032Speter also permits "uucp-old" as an alias for "uucp" and 667038032Speter "uucp-new" as a synonym for "suucp" for consistency. 667138032Speter CONFIG: add POP mailer support (from Kimmo Suominen 667238032Speter <kim@grendel.lut.fi>). 667338032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 667438032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 667538032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 667638032Speter was set; it would get an additional @masquerade.host 667738032Speter added to the address. Problem noted by Peter Wan 667838032Speter of Georgia Tech. 667938032Speter CONFIG: make sure that the local UUCP name is in $=w. From 668038032Speter Jim Murray of Stratus. 668138032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 668238032Speter mailer flag. Briefly, if you are sending to host 668338032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 668438032Speter "foo!baz" remains "foo!baz", and anything else has 668538032Speter the local name prepended. 668638032Speter CONFIG: portability fixes for HP-UX. 668738032Speter DOC: several minor problems fixed in the Install & Op Guide. 668838032Speter MAKEMAP: fix core dump problem on lines that are too long or 668938032Speter which lack newline.

This 672538032Speter makes quite certain that crackers can't use this 672638032Speter class of attack. 672738032Speter Reliability Fix: check return value from fclose() and fsync() 672838032Speter in a few critical places. 672938032Speter Minor problem in initsys() that reversed a condition for 673038032Speter redirecting the output channel on queue runs. It's 673138032Speter not clear this code even does anything. From Eric 673238032Speter Wassenaar of the Dutch National Institute for Nuclear 673338032Speter and High-Energy Physics. 673438032Speter Fix some problems that caused queue runs to do "too much work", 673538032Speter such as double-reading the Errors-To: header. From 673638032Speter Eric Wassenaar. 673738032Speter Error messages on writing the temporary file (including the 673838032Speter data file) were getting suppressed in SMTP -- this 673938032Speter fix causes them to be properly reported. From Eric 674038032Speter Wassenaar. 674138032Speter Some changes to support AF_UNIX sockets -- this will only 674238032Speter really become relevant in the next release, but some 674338032Speter people need it for local patches. From Michael 674438032Speter Corrigan of UC San Diego. 674538032Speter Use dynamically allocated memory (instead of static buffers) 674638032Speter for macros defined in initsys() and settime(); since 674738032Speter these can have different values depending on which 674838032Speter envelope they are in. From Eric Wassenaar. 674938032Speter Improve logging to show ctladdr on to= logging; this tells you 675038032Speter what uid/gid processes ran as. 675138032Speter Fix a problem that caused error messages to be discarded if 675238032Speter the sender address was unparseable for some reason; 675338032Speter this was supposed to fall back to the "return to 675438032Speter postmaster" case. 675538032Speter Improve aliaswait backoff algorithm. 675638032Speter Portability patches for Linux (8.6.3 required another header 675738032Speter file) (from Karl London) and SCO UNIX. 675838032Speter CONFIG: patch prog mailer to not strip host name off of envelope 675938032Speter addresses (so that it matches local again). From 676038032Speter Christopher Davis. 676138032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 676238032Speter this prevents uux from seeing lines with null names like 676338032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 676438032Speter Nakamura of Kyoto University. 676538032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 676638032Speter it shouldn't fail miserably.

Currently, it just says "cannot send for 677638032Speter four hours". 677738032Speter Fix the "Original message received" time generated for 677838032Speter returntosender messages. It was previously listed as 677938032Speter the current time. Bug reported by Eric Hagberg of 678038032Speter Cornell University Medical College. 678138032Speter If there is an error when writing the body of a message, 678238032Speter don't send the trailing dot and wait for a response 678338032Speter in sender SMTP, as this could cause the connection to 678464562Sgshapiro hang up under some bizarre circumstances. From Eric 678538032Speter Wassenaar. 678638032Speter Fix some server SMTP synchronization problems caused when 678738032Speter connections fail during message collection. From 678838032Speter Eric Wassenaar. 678938032Speter Fix a problem that can cause srvrsmtp to reject mail if the 679038032Speter name server is down -- it accepts the RCPT but rejects 679138032Speter the DATA command. Problem reported by Jim Murray of 679238032Speter Stratus. 679338032Speter Fix a problem that can cause core dumps if the config file 679438032Speter incorrectly resolves to a null hostname. Reported by 679538032Speter Allan Johannesen of WPI. 679638032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 679738032Speter by non-root users were not put into 679838032Speter X-Authentication-Warning:s as intended because the 679938032Speter config file hadn't set the PrivacyOptions yet. Fix 680038032Speter from Sven-Ove Westberg of the University of Lulea. 680138032Speter Under very odd circumstances, the alias file rebuild code 680238032Speter could get confused as to whether a database was 680338032Speter open or not. 680438032Speter Check "vendor code" on the end of V lines -- this is 680538032Speter intended to provide a hook for vendor-specific 680638032Speter configuration syntax. (This is a "new feature", 680738032Speter but I've made an exception to my rule in a belief 680838032Speter that this is a highly exceptional case.) 680938032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 681038032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 681138032Speter (from Jon Forrest of UC Berkeley) 681238032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 681338032Speter 681438032Speter8.6.1/8.6 1993/10/08 681538032Speter Portability fixes for A/UX and Encore UMAX V. 681638032Speter Fix error message handling -- if you had a name server down 681738032Speter causing an error during parsing, that message was never 681838032Speter propagated to the queue file. 681938032Speter 682038032Speter8.6/8.6 1993/10/05 682138032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 682238032Speter conf.h (other systems have the same bug). 682338032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 682438032Speter getdtablesize() instead of sysconf(); a disturbingly 682538032Speter large number of systems defined _SC_OPEN_MAX in the 682638032Speter header files but don't have the syscall. 682738032Speter Another patch to really truly ignore MX records in getcanonname 682838032Speter if trymx == FALSE. 682938032Speter Fix problem that caused the "250 IAA25499 Message accepted for 683038032Speter delivery" message to be omitted if there was an error 683138032Speter in the header of the message (e.g., a bad Errors-To: 683264562Sgshapiro line). Pointed out by Michael Corrigan of UCSD. 683338032Speter Announce name of host we are chatting when we get errors; this 683438032Speter is an IDA-ism suggested by Christophe Wolfhugel. 683538032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 683638032Speter Australian Artificial Intelligence Institute), SCO Unix 683738032Speter (from Murray Kucherawy of Hookup Communication Corp.), 683838032Speter NeXT (from Vince DeMarco and myself), Linux (from 683938032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 684038032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 684138032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 684238032Speter Some changes to get around gcc optimizer bugs. From Takahiro 684338032Speter Kanbe. 684438032Speter Fix error recovery in queueup if another tf file of the same 684538032Speter name already exists. Problem stumbled over by Bill 684638032Speter Wisner of The Well. 684738032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 684838032Speter Problem noted by Keith McMillan of Ameritech Services. 684938032Speter Deal with group permissions properly when opening .forward and 685038032Speter :include: files. This relaxes the 8.1C restrictions 685138032Speter slightly more. This includes proper setting of groups 685238032Speter when reading :include: files, allowing you to read some 685338032Speter files that you should be able to read but have previously 685438032Speter been denied unless you owned them or they had "other" 685538032Speter read permission. 685638032Speter Make certain that $j is in $=w (after the .cf is read) so that 685738032Speter if the user is forced to override some silly system, 685838032Speter MX suppression will still work. 685938032Speter Fix a couple of efficiency problems where newstr was double- 686038032Speter calling expensive routines. In at least one case, it 686138032Speter wasn't guaranteed that they would always return the 686238032Speter same result. Problem noted by Christophe Wolfhugel. 686343730Speter Fix null pointer dereference in putoutmsg -- only on an error 686438032Speter condition from a non-SMTP mailer. From Motonori 686538032Speter Nakamura. 686638032Speter Macro expand "C" line class definitions before scanning so that 686738032Speter "CX $Z" works. 686838032Speter Fix problem that caused error message to be sent while still 686938032Speter trying to send the original message if the connection 687038032Speter is closed during a DATA command after getting an error 687138032Speter on an RCPT command (pretty obscure). Problem reported 687238032Speter by John Myers of CMU. 687338032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 687438032Speter term bug. 687538032Speter Fix a nasty bug causing core dumps when returning the "warning: 687638032Speter cannot deliver for N hours -- will keep trying" message; 687738032Speter it only occurred if you had PostmasterCopy set and 687864562Sgshapiro only on some architectures. Although sendmail would 687938032Speter keep trying, it would send error messages on each 688038032Speter queue interval. This is an important fix. 688138032Speter Allow u and g options to take user and group names respectively. 688238032Speter Don't do a chdir into the queue directory in -bt mode to make 688338032Speter ruleset testing a bit easier. 688464562Sgshapiro Don't allow users to turn off logging (using -oL) on the command 688538032Speter line -- command line can only raise, not lower, logging 688638032Speter level. 688738032Speter Set $u to the original recipient on the SMTP transaction or on 688838032Speter the command line. This is only done if there is exactly 688938032Speter one recipient. Technically, this does not meet the 689038032Speter specs, because it does not guarantee a domain on the 689138032Speter address. 689238032Speter Fix a problem that dumped error messages on bad addresses if 689338032Speter you used the -t flag. Problem noted by Josh Smith of 689438032Speter Harvey Mudd College. 689538032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 689638032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 689738032Speter avoid the problem of people who use angle brackets in 689838032Speter their full name information. 689938032Speter Fix a null pointer dereference if you set option "l", have 690038032Speter an Errors-To: header in the message, and have Errors-To: 690138032Speter defined in the config file H lines. From J.R. Oldroyd. 690238032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 690338032Speter wrong when compiling. Suggested by Rick McCarty of TI. 690438032Speter Fix a problem that could pass negative SIZE parameter if the 690538032Speter df file got lost; this would cause servers to always 690638032Speter give a temporary failure, making the problem even worse. 690738032Speter Problem noted by Allan Johannesen of WPI. 690838032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 690938032Speter protocol timeouts (30s default). Requested by Murray 691038032Speter Kucherawy of HookUp Communication Corp. to handle bogus 691138032Speter PC TCP/IP implementations. 691238032Speter Change $w default definition to be just the first component of 691338032Speter the domain name on config level 5. The $j macro defaults 691438032Speter to the FQDN; $m remains as before. This lets well-behaved 691538032Speter config files use any of the short, long, or subdomain 691638032Speter names. 691738032Speter Add makesendmail script in src to try to automate multi-architecture 691838032Speter builds. I know, this is sub-optimal, but it is still 691938032Speter helpful. 692038032Speter Fix very obscure race condition that can cause a queue run to 692138032Speter get a queue file for an already completed job. This 692238032Speter problem has existed for years. Problem noted by the 692338032Speter long suffering Allan Johannesen of WPI. 692438032Speter Fix a problem that caused the raw sender name to be passed to 692538032Speter udbsender instead of the canonified name -- this caused 692638032Speter it to sometimes miss records that it should have found. 692738032Speter Relax check of name on HELO packet so that a program using -bs 692838032Speter that claims to be itself works properly. 692938032Speter Restore rewriting of $: part of address through 2, R, 4 in 693038032Speter buildaddr -- this requires passing a lot of flags to get 693138032Speter it right. Unlike old versions, this ONLY rewrites 693238032Speter recipient addresses, not sender addresses. 693338032Speter Fix a bug that caused core dumps in config files that cannot 693438032Speter resolve /file/name style addresses. Fix from Jonathan 693538032Speter Kamens of OpenVision Technologies. 693638032Speter Fix problem with fcntl locking that can cause error returns to 693738032Speter be lost if the lock is lost; this required fully 693838032Speter queueing everything, dropping the envelope (so errors 693938032Speter would get returned), and then re-reading the queue from 694038032Speter scratch. 694143730Speter Fix a problem that caused aliases that redefine an otherwise 694238032Speter true address to still send to the original address 694338032Speter if and only if the alias failed in certain bizarre 694438032Speter ways (e.g, if they pointed at a list:; syntax address). 694538032Speter Problem pointed out by Jonathan Kamens. 694638032Speter Remove support for frozen configuration files. They caused 694738032Speter more trouble than it was worth. 694838032Speter Fix problem that can cause error messages to get ignored when 694938032Speter using both -odb and -t flags. Problem noted by Rob 695038032Speter McNicholas at U.C. Berkeley. 695138032Speter Include all "normal" variations on hostname in $=w. For example, 695238032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 695338032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 695438032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 695538032Speter the queue. 695638032Speter Reset SmtpPhase global on initial connection creation so that 695738032Speter messages don't come out with stale information. 695838032Speter Pass an "ext" argument to lockfile so that error/log messages 695938032Speter will properly reflect the true filename being locked. 696038032Speter Put all [...] address forms into $=w -- this eliminates the need 696138032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 696238032Speter Myers of CMU. 696338032Speter Fix a bug that can cause qf files to be left around even after 696438032Speter an SMTP RSET command. Problem and fix from Michael 696538032Speter Corrigan. 696638032Speter Don't send a PostmasterCopy to errors when the Precedence: is 696738032Speter negative. Error reports still go to the envelope 696838032Speter sender address. 696938032Speter Add LA_SHORT for load averages. 697038032Speter Lock sendmail.st file when posting statistics. 697138032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 697238032Speter set the size of the TCP send and receive buffers; if you 697338032Speter run over a slow slip line you may need to set these down 697438032Speter (although it would be better to fix the SLIP implementation 697538032Speter so that it's not necessary to recompile every program 697638032Speter that does bulk data transfer). 697738032Speter Allow null defaults on $( ... $) lookups. Problem reported by 697838032Speter Amir Plivatsky. 697938032Speter Diagnose crufty S and V config lines. This resulted from an 698038032Speter observation that some people were using the SITE macro 698138032Speter without the SITECONFIG macro first, which was causing 698238032Speter bogus config files that were not caught. 698338032Speter Fix makemap -f flag to turn off case folding (it was turning it 698438032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 698538032Speter Fix a problem that caused multiple error messages to be sent if 698638032Speter you used "sendmail -t -oem -odb", your system uses fcntl 698738032Speter locking, and one of the recipient addresses is unknown. 698838032Speter Reset uid earlier in include() so that recursive .forwards or 698938032Speter :include:s don't use the wrong uid. 699038032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 699138032Speter called, the code to recover the descriptor was broken. 699238032Speter This sometimes (only sometimes) caused problems with the 699338032Speter alias file. Fix from Motonori Nakamura. 699438032Speter Fix a problem that caused aliaswait to go into infinite recursion 699538032Speter if the @:@ metasymbol wasn't found in the alias file. 699638032Speter Improve error message on newaliases if database files cannot be 699738032Speter opened or if running with no database format defined. 699838032Speter Do a better estimation of the size of error messages when NoReturn 699938032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 700038032Speter Fix a problem causing the "c" option (don't connect to expensive 700138032Speter mailers) to be ignored in SMTP. Problem noted and the 700238032Speter solution suggested by Robert Elz of The University of 700338032Speter Melbourne. 700438032Speter Improve connection caching algorithm by passing "[host]" to 700538032Speter hostsignature, which strips the square brackets and 700638032Speter returns the real name. This allows mailertable entries 700738032Speter to match regular entries. 700838032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 700938032Speter feature, even if it doesn't work right. 701038032Speter Catch and log attempts to try the "wiz" command in server SMTP. 701138032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 701238032Speter Be more generous at assigning $z to the home directory -- do this 701338032Speter for programs that are specified through a .forward file. 701438032Speter Fix from Andrew Chang of Sun Microsystems. 701538032Speter Always save a fatal error message in preference to a non-fatal 701638032Speter error message so that the "subject" line of return 701738032Speter messages is the best possible. 701838032Speter CONFIG: reduce the number of quotes needed to quote configuration 701938032Speter parameters with commas: two quotes should work now, e.g., 702038032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 702138032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 702238032Speter connections (domain-ized UUCP). 702338032Speter CONFIG: fix bug in default maps (-o must be before database file 702438032Speter name). Pointed out by Christophe Wolfhugel. 702538032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 702638032Speter DNS. This would presumably be used in UUCP islands. 702738032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 702838032Speter CONFIG: log $u in Received: line. This is in technical violation 702938032Speter of the standards, since it doesn't guarantee a domain 703043730Speter on the address. 703138032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 703238032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 703338032Speter the "m" flag should you want it. Apparently some Solaris 2.2 703438032Speter installations can't handle multiple local recipients. 703538032Speter Problem noted by Josh Smith. 703638032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 703738032Speter CONFIG: change default version level from 4 to 5. 703838032Speter CONFIG: add FEATURE(nullclient) to create a config file that 703938032Speter forwards all mail to a hub without ever looking at the 704038032Speter addresses in any detail. 704138032Speter CONFIG: properly strip mailer: information off of relays when 704238032Speter used to change .BITNET form into %-hack form. 704338032Speter CONFIG: fix a problem that caused infinite loops if presented 704438032Speter with an address such as "!foo". 704538032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 704638032Speter the reverse "PTR" mapping is broken. There's a better 704738032Speter way to do this, but the change is fairly major and I 704838032Speter want to hold it for another release. Problem noted by 704938032Speter Bret Marquis. 705038032Speter 705138032Speter8.5/8.5 1993/07/23 705238032Speter Serious bug: if you used a command line recipient that was unknown 705338032Speter sendmail would not send a return message (it was treating 705438032Speter everything as though it had an SMTP-style client that 705538032Speter would do the return itself). Problem noted by Josh Smith. 705638032Speter Change "trymx" option in getcanonname() to ignore all MX data, 705738032Speter even during a T_ANY query. This actually didn't break 705838032Speter anything, because the only time you called getcanonname 705938032Speter with !trymx was if you already knew there were no MX 706038032Speter records, but it is somewhat cleaner. From Motonori 706138032Speter Nakamura. 706238032Speter Don't call getcanonname from getmxrr if you already know there 706338032Speter are no DNS records matching the name. 706438032Speter Fix a problem causing error messages to always include "The 706538032Speter original message was received ... from localhost". 706638032Speter The correct original host information is now included. 706738032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 706838032Speter version of "test" doesn't have the -x flag). Change it 706938032Speter to use -f instead. From John Myers. 707038032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 707138032Speter esmtp -- it should be smtp. 707238032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 707338032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 707438032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 707538032Speter this cleans up the configs somewhat. This fixes a serious 707638032Speter problem that caused route-addrs to get mistaken as relays, 707738032Speter pointed out by John Myers. WARNING: this also causes 707838032Speter the default on SMART_HOST to change from "suucp" to 707938032Speter "relay" if you have MAILER(smtp) specified. 708038032Speter 708138032Speter8.4/8.4 1993/07/22 708238032Speter Add option `w'. If you receive a message that comes to you because 708338032Speter you are the best (lowest preference) target of an MX, and 708438032Speter you haven't explicitly recognized the source MX host in 708538032Speter your .cf file, this option will cause you to try the target 708638032Speter host directly (as if there were no MX for it at all). If 708738032Speter `w' is not set, this case is a configuration error. 708864562Sgshapiro Beware: if `w' is set, senders may get bogus errors like 708938032Speter "message timed out" or "host unknown" for problems that 709038032Speter are really configuration errors. This option is 709138032Speter disrecommended, provided only for compatibility with 709238032Speter UIUC sendmail. 709338032Speter Fix a problem that caused the incoming socket to be left open 709438032Speter when sendmail forks after the DATA command. This caused 709538032Speter calling systems to wait in FIN_WAIT_2 state until the 709638032Speter entire list was processed and the child closed -- a 709738032Speter potentially prodigious amount of time. Problem noted 709838032Speter by Neil Rickert. 709938032Speter Fix problem (created in 6.64) that caused mail sent to multiple 710038032Speter addresses, one of which was a bad address, to completely 710138032Speter suppress the sending of the message. This changes 710238032Speter handling of EF_FATALERRS somewhat, and adds an 710338032Speter EF_GLOBALERRS flag. This also fixes a potential problem 710438032Speter with duplicate error messages if there is a syntax error 710538032Speter in the header of a message that isn't noticed until late 710638032Speter in processing. Original problem pointed out by Josh Smith 710738032Speter of Harvey Mudd College. This release includes quite a bit 710838032Speter of dickering with error handling (see below). 710938032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 711038032Speter will only hurt already-broken software and should help 711138032Speter humans. 711238032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 711338032Speter compiled in. It would never read the alias file. 711438032Speter Repair unbalanced `)' and `>' (the "open" versions are already 711564562Sgshapiro repaired). 711638032Speter Logging of "done" in dropenvelope() was incorrect: it would 711738032Speter log this even when the queue file still existed. Change 711838032Speter this to only log "done" (at log level 11) when the 711938032Speter queue file is actually removed. From John Myers. 712038032Speter Log "lost connection" in server SMTP at log level 20 if there 712138032Speter is no pending transaction. Some senders just close the 712238032Speter connection rather than sending QUIT. 712338032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 712438032Speter domains that do not have MX records -- this would cause 712538032Speter the subsequent host name lookup to fail. The problem 712638032Speter only occurred if you had FEATURE(nocanonify) set. 712738032Speter Problem noted by Rick McCarty of Texas Instruments. 712838032Speter Fix invocation of setvbuf when passed a -X flag -- I had 712938032Speter unwittingly used an ANSI C extension, and this caused 713038032Speter core dumps on some machines. 713138032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 713238032Speter Previously it just gave an empty send queue, which 713338032Speter then gave either "Need RCPT (recipient)" at the DATA 713438032Speter (confusing, since you had given an RCPT command which 713538032Speter returned 250) or just dropped the email, depending on 713638032Speter whether you were running VERBose mode. Now it usually 713738032Speter diagnoses this case as "aliasing/forwarding loop broken". 713838032Speter Unfortunately, it still doesn't adequately diagnose 713938032Speter some true error conditions. 714038032Speter Add internal concept of "warning messages" using 6xx codes. 714138032Speter These are not reported only to Postmaster. Unbalanced 714238032Speter parens, brackets, and quotes are printed as 653 codes. 714338032Speter They are always mapped to 5xx codes before use in SMTP. 714438032Speter Clean up error messages to tell both the actual address that 714564562Sgshapiro failed and the alias they arose from. This makes it 714638032Speter somewhat easier to diagnose problems. Difficulty noted 714738032Speter by Motonori Nakamura. 714838032Speter Fix a problem that inappropriately added a ctladdr to addresses 714938032Speter that shouldn't have had one during a queue run. This 715038032Speter caused error messages to be handled differently during 715138032Speter a queue run than a direct run. 715238032Speter Don't print the qf name and line number if you get errors during 715338032Speter the direct run of the queue from srvrsmtp -- this was 715438032Speter just extra stuff for users to crawl through. 715538032Speter Put command line flags on second line of pid file so you can 715638032Speter auto-restart the daemon with all appropriate arguments. 715738032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 715838032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 715938032Speter restart it. 716038032Speter Remove the ``setuid(getuid())'' in main -- this caused the 716138032Speter IDENT daemon to screw up. This required that I change 716238032Speter HASSETEUID to HASSETREUID and complicate the mode 716338032Speter changing somewhat because both Ultrix and SunOS seem 716438032Speter to have a bug causing seteuid() to set the saved uid 716538032Speter as well as the effective. The program test/t_setreuid.c 716638032Speter will test to see if your implementation of setreuid(2) 716738032Speter is appropriately functional. 716838032Speter The FallBackMX (option V) handling failed to properly identify 716938032Speter fallback to yourself -- most of the code was there, 717038032Speter but it wasn't being enabled. Problem noted by Murray 717138032Speter Kucherawy of the University of Waterloo. 717238032Speter Change :include: open timeout from ETIMEDOUT to an internal 717338032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 717438032Speter with CurHostName" in error messages, which can be 717538032Speter confusing. Reported by Jonathan Kamens of OpenVision 717638032Speter Technologies. 717738032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 717838032Speter process group id. The original fix was to get around 717938032Speter some problems with recalcitrant MUAs, but it breaks 718038032Speter any call from a shell that creates a process group id 718138032Speter different from the process id. I could try to fix 718238032Speter this by diddling the tty owner (using tcsetpgrp or 718338032Speter equivalent) but this is too likely to break other 718438032Speter things. 718538032Speter Portability changes: 718638032Speter Support -M as equivalent to -oM on Ultrix -- apparently 718738032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 718838032Speter instead of using standard flags. Oh joy. This 718938032Speter behavior reported by Jon Giltner of University 719038032Speter of Colorado. 719138032Speter SGI IRIX -- this includes several changes that should 719238032Speter help other strict ANSI compilers. 719338032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 719438032Speter Corporation. 719538032Speter Solaris running the Sun C compiler (which despite the 719638032Speter documentation apparently doesn't define 719738032Speter __STDC__ by default). 719838032Speter ConvexOS from Eric Schnoebelen of Convex. 719938032Speter Sony NEWS workstations and Omron LUNA workstations from 720038032Speter Motonori Nakamura. 720138032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 720238032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 720338032Speter several people have made a good argument that this 720438032Speter creates more problems than it solves (although this 720538032Speter may prove painful in the short run). 720638032Speter CONFIG: generalize all the relays to accept a "mailer:host" 720738032Speter format. 720838032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 720938032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 721038032Speter addresses are also passed through this ruleset. 721138032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 721238032Speter internet-style addresses would "fall off the end" of 721338032Speter ruleset zero and be interpreted as local -- however, 721438032Speter the angle brackets confused the recursive call. 721538032Speter These are now diagnosed as "Unrecognized host name". 721638032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 721738032Speter ifdef(`_MAILER_USENET_') instead of 721838032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 721938032Speter of SINTEF RUNIT, Oslo. 722038032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 722138032Speter early in ruleset 0; this allows .mc authors to bypass 722238032Speter things like the "short circuit" code for local addresses. 722338032Speter Prompted by a comment by Bill Wisner of The Well. 722438032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 722538032Speter esmtp) to send SMTP mail. This allows you to default 722638032Speter to esmtp but use a mailertable or other override to 722738032Speter deal with broken servers. This logic was pointed out 722838032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 722938032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 723038032Speter environments. Ugly as sin. 723138032Speter 723238032Speter8.3/8.3 1993/07/13 723338032Speter Fix setuid problems introduced in 8.2 that caused messages 723438032Speter like "Cannot create qfXXXXXX: Invalid argument" 723538032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 723638032Speter involved a new compile flag "HASSETEUID" that takes 723738032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 723838032Speter that the POSIX interface is broken enough to break 723938032Speter some systems badly. This includes some fixes for 724038032Speter HP-UX. Also fixes problems where the real uid is 724138032Speter not reset properly on startup (from Neil Rickert). 724238032Speter Fix a problem that caused timed out messages to not report the 724338032Speter addresses that timed out. Error messages are also more 724438032Speter "user friendly". 724538032Speter Drop required bandwidth on connections from 64 bytes/sec to 724638032Speter 16 bytes/sec. 724738032Speter Further Solaris portability changes -- doesn't require the BSD 724838032Speter compatibility library. This also adds a new 724938032Speter "HASGETDTABLESIZE" compile flag which can be used if 725038032Speter you want to use getdtablesize(2) instead of sysconf(2). 725138032Speter These are loosely based on changes from David Meyer at 725238032Speter University of Oregon. This now seems to work, at least 725343730Speter for quick test cases. 725438032Speter Fix a problem that can cause duplicate error messages to be 725538032Speter sent if you are in SMTP, you send to multiple addresses, 725638032Speter and at least one of those addresses is good and points 725738032Speter to an account that has a .forward file (whew!). 725838032Speter Fix a problem causing messages to be discarded if checkcompat() 725938032Speter returned EX_TEMPFAIL (because it didn't properly mark 726038032Speter the "to" address). Problem noted by John Myers. 726138032Speter Fix dfopen to return NULL if the open failed; I was depending 726238032Speter on fdopen(-1) returning NULL, which isn't the case. This 726338032Speter isn't serious, but does result in weird error diagnoses. 726438032Speter From Michael Corrigan. 726538032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 726638032Speter messages sent through UUCP-family mailers. Suggested 726738032Speter by Bill Wisner of The Well. 726838032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 726938032Speter include a "uucp-dom" mailer that uses domain-style 727038032Speter addressing. Suggested by Bill Wisner. 727138032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 727238032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 727338032Speter Christophe Wolfhugel. 727438032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 727538032Speter 727638032Speter8.2/8.2 1993/07/11 727738032Speter Don't drop out on config file parse errors in -bt mode. 727838032Speter On older configuration files, assume option "l" (use Errors-To 727938032Speter header) for back compatibility. NOTE: this DOES NOT 728038032Speter imply an endorsement of the Errors-To: header in any way. 728138032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 728238032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 728338032Speter SMTP server to give an error on this command, and 728438032Speter logging it in the transcript can be confusing. Fix 728538032Speter from Bill Wisner. 728638032Speter IRIX compatibility changes provided by Dan Rich 728738032Speter <drich@sandman.lerc.nasa.gov>. 728838032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 728938032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 729038032Speter <juo@klinzhai.rutgers.edu> 729138032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 729238032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 729338032Speter match the other flags in that file. 729438032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 729538032Speter Save h_errno in mci struct and improve error message display. 729664562Sgshapiro Changes from Eric Wassenaar. 729738032Speter Open /dev/null for the transcript if the create of the xf file 729838032Speter failed; this avoids at least one possible null pointer 729938032Speter reference in very weird cases. From Eric Wassenaar. 730038032Speter Clean up statistics gathering; it was over-reporting because of 730138032Speter forks. From Eric Wassenaar. 730238032Speter Fix problem that causes old Return-Path: line to override new 730338032Speter Return-Path: line (conf.c needs H_FORCE to avoid 730438032Speter re-using old value). From Motonori Nakamura. 730538032Speter Fix broken -m flag in K definition -- even if -m (match only) 730638032Speter was specified, it would still replace the key with the 730738032Speter value. Noted by Rick McCarty of Texas Instruments. 730838032Speter If the name server timed out over several days, no "timed out" 730938032Speter message would ever be sent back. The timeout code 731038032Speter has been moved from markfailure() to dropenvelope() 731138032Speter so that all such failures should be diagnosed. Pointed 731238032Speter out by Christophe Wolfhugel and others. 731338032Speter Relax safefile() constraints: directories in an include or 731438032Speter forward path must be readable by self if the controlling 731538032Speter user owns the entry, readable by all otherwise (e.g., 731638032Speter when reading your .forward file, you have to own and 731738032Speter have X permission in it; everyone needs X permission in 731838032Speter the root and directories leading up to your home); 731938032Speter include files must be readable by anyone, but need not 732038032Speter be owned by you. 732138032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 732238032Speter reading a .forward file; this gets around some problems 732338032Speter on NFS mounts if root permission is not exported and 732438032Speter the user's home directory isn't x'able. 732538032Speter Additional NeXT portability enhancements from Axel Zinser. 732638032Speter Additional HP-UX portability enhancements from Brian Bullen. 732738032Speter Add a timeout around SMTP message writes; this assumes you can 732838032Speter get throughput of at least 64 bytes/second. Note that 732938032Speter this does not impact the "datafinal" default, which 733038032Speter is separate; this is just intended to work around 733138032Speter network clogs that will occur before the final dot 733238032Speter is sent. From Eric Wassenaar. 733338032Speter Change map code to set the "include null" flag adaptively -- 733438032Speter it initially tries both, but if it finds anything 733538032Speter matching without a null it never tries again with a 733638032Speter null and vice versa. If -N is specified, it never 733738032Speter tries without the null and creates new maps with a 733838032Speter null byte. If -O is specified, it never tries with 733938032Speter the null (for efficiency). If -N and -O are specified, 734064562Sgshapiro you get -NO (get it?) lookup at all, so this would 734138032Speter be a bad idea. If you don't specify either -N or -O, 734238032Speter it adapts. 734338032Speter Fix recognition of "same from address" so that MH submissions 734438032Speter will insert the appropriate full name information; 734538032Speter this used to work and got broken somewhere along the 734638032Speter way. 734738032Speter Some changes to eliminate some unnecessary SYSERRs in the 734838032Speter log. For example, if you lost a connection, don't 734938032Speter bother reporting that fact on the connection you lost. 735038032Speter Add some "extended debugging" flags to try to track down 735138032Speter why we get occasional problems with file descriptor 735238032Speter one being closed when execing a mailer; it seems to 735338032Speter only happen when there has been another error in the 735438032Speter same transaction. This requires XDEBUG, defined 735538032Speter by default in conf.h. 735638032Speter Add "-X filename" command line flag, which logs both sides of 735738032Speter all SMTP transactions. This is intended ONLY for 735838032Speter debugging bad implementations of other mailers; start 735938032Speter it up, send a message from a mailer that is failing, 736038032Speter and then kill it off and examine the indicated log. 736138032Speter This output is not intended to be particularly human 736238032Speter readable. This also adds the HASSETVBUF compile 736338032Speter flag, defaulted on if your compiler defines __STDC__. 736438032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 736538032Speter have a local net that should get direct connects, you 736638032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 736738032Speter See cf/README for an example. 736838032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 736938032Speter sites that don't use the -d flag. 737038032Speter CONFIG: hide recipient addresses as well as sender addresses 737138032Speter behind $M if FEATURE(allmasquerade) is specified; this 737238032Speter has been requested by several people, but can break 737338032Speter local aliases. For example, if you mail to "localalias" 737438032Speter this will be rewritten as "localalias@masqueradehost"; 737538032Speter although initial delivery will work, replies will be 737638032Speter broken. Use it sparingly. 737738032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 737838032Speter to qualified domains in headers. I believe this is 737938032Speter largely equivalent to the IDA feature of the same name. 738038032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 738138032Speter to override the "system name" as your UUCP name -- 738238032Speter in particular, to use domain-ized UUCP names. From 738338032Speter Bill Wisner of The Well. 738438032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 738538032Speter first. This is currently unused in the config files, 738638032Speter but could be used in a mailertable entry. 738738032Speter 738838032Speter8.1C/8.1B 1993/06/27 738938032Speter Serious security bug fix: it was possible to read any file on 739038032Speter the system, regardless of ownership and permissions. 739138032Speter If a subroutine returns a fully qualified address, return it 739238032Speter immediately instead of feeding it back into rewriting. 739338032Speter This fixes a problem with mailertable lookups. 739438032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 739538032Speter 739638032Speter8.1B/8.1A 1993/06/12 739738032Speter Serious bug fix: pattern matching backup algorithm stepped by 739838032Speter two tokens in classes instead of one.
