Problem detected by 1282017Sgshapiro Cade Cairns of SecurityFocus. 1382017Sgshapiro Avoid leaking recipient information in unrelated DSNs. This could 1482017Sgshapiro happen if a connection is aborted, several mails had been 1582017Sgshapiro scheduled for delivery via that connection, and the timeout 1682017Sgshapiro is reached such that several DSNs are sent next. Problem 1782017Sgshapiro noted by Dileepan Moorkanat of Hewlett-Packard. 1882017Sgshapiro Fix a possible segmentation violation when specifying too many 1982017Sgshapiro wildcard operators in a rule. Problem detected by 2082017Sgshapiro Werner Wiethege. 2182017Sgshapiro Avoid a segmentation fault on non-matching Hesiod lookups.

This could terminate the current process without 2780785Sgshapiro starting a new daemon. Problem reported by Wolfgang Breyha 2880785Sgshapiro of SE Netway Communications. 2980785Sgshapiro Only apply MaxHeadersLength when receiving a message via SMTP or 3080785Sgshapiro the command line. Problem noted by Andrey J. Melnikoff. 3180785Sgshapiro When finding the system's local hostname on an IPv6-enabled system 3280785Sgshapiro which doesn't have any IPv6 interface addresses, fall back 3380785Sgshapiro to looking up only IPv4 addresses. Problem noted by Tim 3480785Sgshapiro Bosserman of EarthLink. 3580785Sgshapiro When commands were being rejected due to check_relay or TCP 3680785Sgshapiro Wrappers, the ETRN command was not giving a response. 3780785Sgshapiro Incoming IPv4 connections on a Family=inet6 daemon (using 3880785Sgshapiro IPv4-mapped addresses) were incorrectly labeled as "may be 3980785Sgshapiro forged". Problem noted by Per Steinar Iversen of Oslo 4080785Sgshapiro University College. 4180785Sgshapiro Shutdown address test mode cleanly on SIGTERM. Problem noted by 4280785Sgshapiro Greg King of the OAO Corporation. 4380785Sgshapiro Restore the original real uid (changed in main() to prevent 4480785Sgshapiro out of band signals) before invoking a delivery agent. 4580785Sgshapiro Some delivery agents use this for the "From " envelope 4680785Sgshapiro "header". Problem noted by Leslie Carroll of the 4780785Sgshapiro University at Albany. 4880785Sgshapiro Mark closed file descriptors properly to avoid reuse. Problem 4980785Sgshapiro noted by Jeff Bronson of J.D. Bronson, Inc. 5080785Sgshapiro Setting Timeout options on the command line will also override 5180785Sgshapiro their sub-suboptions in the .cf file, e.g., -O 5280785Sgshapiro Timeout.queuereturn=2d will set all queuereturn timeouts 5380785Sgshapiro to 2 days. Problem noted by Roger B.A. Klorese. 5480785Sgshapiro Portability: 5580785Sgshapiro BSD/OS has a broken setreuid() implementation. Problem 5680785Sgshapiro noted by Vernon Schryver of Rhyolite Software. 5780785Sgshapiro BSD/OS has /dev/urandom(4) (as of version 4.1/199910 ?). 5880785Sgshapiro Noted by Vernon Schryver of Rhyolite Software. 5980785Sgshapiro BSD/OS has fchown(2). Noted by Dave Yadallee of Netline 6080785Sgshapiro 2000 Internet Solutions Inc. 6180785Sgshapiro Solaris 2.X and later have strerror(3).

Problem noted by Liyuan Zhou. 6580785Sgshapiro 6677349Sgshapiro8.11.4/8.11.4 2001/05/28 6777349Sgshapiro Clean up signal handling routines to reduce the chances of heap 6877349Sgshapiro corruption and other potential race conditions. 6977349Sgshapiro Terminating and restarting the daemon may not be 7077349Sgshapiro instantaneous due to this change. Also, non-root users can 7177349Sgshapiro no longer send out-of-band signals. Problem reported by 7277349Sgshapiro Michal Zalewski of BindView. 7377349Sgshapiro If LogLevel is greater than 9 and SASL fails to negotiate an 7477349Sgshapiro encryption layer, avoid core dump logging the encryption 7577349Sgshapiro strength. Problem noted by Miroslav Zubcic of Crol. 7677349Sgshapiro If a server offers "AUTH=" and "AUTH " and the list of mechanisms is 7777349Sgshapiro different in those two lines, sendmail might not have 7877349Sgshapiro recognized (and used) all of the offered mechanisms. 7977349Sgshapiro Fix an IP address lookup problem on Solaris 2.0 - 2.3. Patch 8077349Sgshapiro from Kenji Miyake. 8177349Sgshapiro This time, really don't use the .. directory when expanding 8277349Sgshapiro QueueDirectory wildcards. 8377349Sgshapiro If a process is interrupted while closing a map, don't try to close 8477349Sgshapiro the same map again while exiting. 8577349Sgshapiro Allow local mailers (F=l) to contact remote hosts (e.g., via 8677349Sgshapiro LMTP). Problem noted by Norbert Klasen of the University 8777349Sgshapiro of Tuebingen. 8877349Sgshapiro If Timeout.QueueReturn was set to a value less the time it took 8977349Sgshapiro to write a new queue file (e.g., 0 seconds), the bounce 9077349Sgshapiro message would be lost. Problem noted by Lorraine L Goff of 9177349Sgshapiro Oklahoma State University. 9277349Sgshapiro Pass map argument vector into map rewriting engine for the regex 9377349Sgshapiro and prog map types. Problem noted by Stephen Gildea of 9477349Sgshapiro InTouch Systems, Inc. 9577349Sgshapiro When closing an LDAP map due to a temporary error, close all of the 9677349Sgshapiro other LDAP maps which share the original map's connection 9777349Sgshapiro to the LDAP server. Patch from Victor Duchovni of 9877349Sgshapiro Morgan Stanley. 9977349Sgshapiro To detect changes of NDBM aliases files check the timestamp of the 10077349Sgshapiro .pag file instead of the .dir file. Problem noted by Neil 10177349Sgshapiro Rickert of Northern Illinois University. 10277349Sgshapiro Don't treat temporary hesiod lookup failures as permanent. Patch 10377349Sgshapiro from Werner Wiethege. 10477349Sgshapiro If ClientPortOptions is set, make sure to create the outgoing socket 10577349Sgshapiro with the family set in that option. Patch from Sean Farley. 10677349Sgshapiro Avoid a segmentation fault trying to dereference a NULL pointer 10777349Sgshapiro when logging a MaxHopCount exceeded error with an empty 10877349Sgshapiro recipient list. Problem noted by Chris Adams of HiWAAY 10977349Sgshapiro Internet Services. 11077349Sgshapiro Fix DSN for "Too many hops" bounces.

Problem noticed by 11377349Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 11477349Sgshapiro Portability: 11577349Sgshapiro OpenBSD has a broken setreuid() implementation. 11677349Sgshapiro CONFIG: Undo change from 8.11.1: change 501 SMTP reply code back 11777349Sgshapiro to 553 since it is allowed by DRUMS. 11877349Sgshapiro CONFIG: Add OSTYPE(freebsd4) for FreeBSD 4.X. 11977349Sgshapiro DEVTOOLS: install.sh did not properly handle paths in the source 12077349Sgshapiro file name argument. Noted by Kari Hurtta of the Finnish 12177349Sgshapiro Meteorological Institute. 12277349Sgshapiro DEVTOOLS: Add FAST_PID_RECYCLE to compile time options for OpenBSD 12377349Sgshapiro since it generates random process ids. 12477349Sgshapiro PRALIASES: Add back adaptive algorithm to deal with different endings 12577349Sgshapiro of entries in the database (with/without trailing '\0'). 12677349Sgshapiro Patch from John Beck of Sun Microsystems. 12777349Sgshapiro New Files: 12877349Sgshapiro cf/ostype/freebsd4.m4 12977349Sgshapiro 13073188Sgshapiro8.11.3/8.11.3 2001/02/27 13173188Sgshapiro Prevent a segmentation fault when a bogus value was used in the 13273188Sgshapiro LDAPDefaultSpec option's -r, -s, or -M flags and if a bogus 13373188Sgshapiro option was used. Problem noted by Allan E Johannesen of 13473188Sgshapiro Worcester Polytechnic Institute. 13573188Sgshapiro Prevent "token too long" message by shortening {currHeader} which 13673188Sgshapiro could be too long if the last copied character was a quote. 13773188Sgshapiro Problem detected by Jan Krueger of digitalanswers 13873188Sgshapiro communications consulting gmbh. 13973188Sgshapiro Additional IPv6 check for unspecified addresses. Patch from 14073188Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 14173188Sgshapiro Do not ignore the ClientPortOptions setting if DaemonPortOptions 14273188Sgshapiro Modifier=b (bind to same interface) is set and the 14373188Sgshapiro connection came in from the command line. 14473188Sgshapiro Do not bind to the loopback address if DaemonPortOptions 14573188Sgshapiro Modifier=b (bind to same interface) is set. Patch from 14673188Sgshapiro John Beck of Sun Microsystems. 14773188Sgshapiro Properly deal with open failures on non-optional maps used in 14873188Sgshapiro check_* rulesets by returning a temporary failure. 14973188Sgshapiro Buffered file I/O files were not being properly fsync'ed to disk 15073188Sgshapiro when they were committed. 15173188Sgshapiro Properly encode '=' for the AUTH= parameter of the MAIL command. 15273188Sgshapiro Problem noted by Hadmut Danisch. 15373188Sgshapiro Under certain circumstances the macro {server_name} could be set 15473188Sgshapiro to the wrong hostname (of a previous connection), which may 15573188Sgshapiro cause some rulesets to return wrong results. This would 15673188Sgshapiro usually cause mail to be queued up and delivered later on. 15773188Sgshapiro Ignore F=z (LMTP) mailer flag if $u is given in the mailer A= 15873188Sgshapiro equate. Problem noted by Motonori Nakamura of Kyoto 15973188Sgshapiro University. 16073188Sgshapiro Work around broken accept() implementations which only partially 16173188Sgshapiro fill in the peer address if the socket is closed before 16273188Sgshapiro accept() completes. 16373188Sgshapiro Return an SMTP "421" temporary failure if the data file can't be 16473188Sgshapiro opened where the "354" reply would normally be given. 16573188Sgshapiro Prevent a CPU loop in trying to expand a macro which doesn't exist 16673188Sgshapiro in a queue run. Problem noted by Gordon Lack of Glaxo 16773188Sgshapiro Wellcome. 16873188Sgshapiro If delivering via a program and that program exits with EX_TEMPFAIL, 16973188Sgshapiro note that fact for the mailq display instead of just showing 17073188Sgshapiro "Deferred". Problem noted by Motonori Nakamura of Kyoto 17173188Sgshapiro University. 17273188Sgshapiro If doing canonification via /etc/hosts, try both the fully 17373188Sgshapiro qualified hostname as well as the first portion of the 17473188Sgshapiro hostname. Problem noted by David Bremner of the 17573188Sgshapiro University of New Brunswick. 17673188Sgshapiro Portability: 17773188Sgshapiro Fix a compilation problem for mail.local and rmail if SFIO 17873188Sgshapiro is in use.

Miller of Courtesan Consulting. 18573188Sgshapiro Unixware 7.1.1 doesn't allow h_errno to be set directly if 18673188Sgshapiro sendmail is being compiled with -kthread. Problem 18773188Sgshapiro noted by Orion Poplawski of CQG, Inc. 18873188Sgshapiro CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and 18973188Sgshapiro current left hand side for $LHS in virtuser files. 19073188Sgshapiro DEVTOOLS: Do not pass make targets to recursive Build invocations. 19173188Sgshapiro Problem noted by Jeff Bronson of J.D. Bronson, Inc. 19273188Sgshapiro MAIL.LOCAL: In LMTP mode, do not return errors regarding problems 19373188Sgshapiro storing the temporary message file until after the remote 19473188Sgshapiro side has sent the final DATA termination dot. Problem 19573188Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic 19673188Sgshapiro Institute. 19773188Sgshapiro MAIL.LOCAL: If LMTP mode is set, give a temporary error if users 19873188Sgshapiro are also specified on the command line. Patch from 19973188Sgshapiro Motonori Nakamura of Kyoto University. 20073188Sgshapiro PRALIASES: Skip over AliasFile specifications which aren't based on 20173188Sgshapiro database files (i.e., only show dbm, hash, and btree). 20273188Sgshapiro Renamed Files: 20373188Sgshapiro devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x 20473188Sgshapiro 20571345Sgshapiro8.11.2/8.11.2 2000/12/29 20671345Sgshapiro Prevent a segmentation fault when trying to set a class in 20771345Sgshapiro address test mode due to a negative array index. Audit 20871345Sgshapiro other array indexing. This bug is not believed to be 20971345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 21071345Sgshapiro Schools" project (IdS). 21171345Sgshapiro Add an FFR (for future release) to drop privileges when using 21271345Sgshapiro address test mode. This will be turned on in 8.12. It can 21371345Sgshapiro be enabled by compiling with: 21471345Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 21571345Sgshapiro in your devtools/Site/site.config.m4 file. Suggested by 21671345Sgshapiro Michal Zalewski of the "Internet for Schools" project (IdS). 21771345Sgshapiro Fix potential problem with Cyrus-SASL security layer which may have 21871345Sgshapiro caused I/O errors, especially for mechanism DIGEST-MD5. 21971345Sgshapiro When QueueSortOrder was set to host, sendmail might not read 22071345Sgshapiro enough of the queue file to determine the host, making the 22171345Sgshapiro sort sub-optimal. Problem noted by Jeff Earickson of 22271345Sgshapiro Colby College. 22371345Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 22471345Sgshapiro RFC 1891) but don't have FAILURE as value. 22571345Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 22671345Sgshapiro This implies that every change to SASL related files requires 22771345Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 22871345Sgshapiro mechanisms (in form of shared libraries). 22971345Sgshapiro Properly set the STARTTLS related macros during a queue run for 23071345Sgshapiro a cached connection. Bug reported by Michael Kellen of 23171345Sgshapiro NxNetworks, Inc. 23271345Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 23371345Sgshapiro client name. 23471345Sgshapiro Include original length of bad field/header when reporting 23571345Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 23671345Sgshapiro the Universitat Regensburg. 23771345Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 23871345Sgshapiro DeliveryMode queue. Problem noted by Ric Anderson of the 23971345Sgshapiro University of Arizona. 24071345Sgshapiro Fix LDAP map -m (match only) flag. Problem noted by Jeff Giuliano 24171345Sgshapiro of Collective Technologies. 24271345Sgshapiro Avoid using a negative argument for sleep() calls when delaying answers 24371345Sgshapiro to EXPN/VRFY commands on systems which respond very slowly. 24471345Sgshapiro Problem noted by Mikolaj J. Habryn of Optus Internet 24571345Sgshapiro Engineering. 24671345Sgshapiro Make sure the F=u flag is set in the default prog mailer 24771345Sgshapiro definition. Problem noted by Kari Hurtta of the Finnish 24871345Sgshapiro Meteorological Institute. 24971345Sgshapiro Fix IPv6 check for unspecified addresses. Patch from 25071345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 25171345Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 25271345Sgshapiro Meteorological Institute. 25371345Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 25471345Sgshapiro of the parameters to find Family= setting before trying to 25571345Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 25671345Sgshapiro Kletnieks of Virginia Tech. 25771345Sgshapiro When delivering to a file directly from an alias, do not call 25871345Sgshapiro initgroups(); instead use the DefaultUser group information. 25971345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 26071345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 26171345Sgshapiro created. Otherwise, sendmail can not remove it upon 26271345Sgshapiro close. Problem noted by Werner Wiethege. 26371345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 26471345Sgshapiro overall connections, not the number of connections per 26571345Sgshapiro socket. A future version may change this to per socket 26671345Sgshapiro counting. 26771345Sgshapiro Portability: 26871345Sgshapiro Clean up libsmdb so it functions properly on platforms 26971345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t). Problem 27071345Sgshapiro noted by Rein Tollevik of Basefarm AS. 27171345Sgshapiro Fix man page formatting for compatibility with Solaris' 27271345Sgshapiro whatis. From Stephen Gildea of InTouch Systems, Inc. 27371345Sgshapiro UnixWare 7 includes snprintf() support. From Larry 27471345Sgshapiro Rosenman. 27571345Sgshapiro IPv6 changes for platforms using KAME.

Problem noted by Bob Hughes 27971345Sgshapiro of Pacific Access. 28071345Sgshapiro Add preliminary support for AIX 5. Contributed by 28171345Sgshapiro Valdis Kletnieks of Virginia Tech. 28271345Sgshapiro Solaris 9 load average support from Andrew Tucker of Sun 28371345Sgshapiro Microsystems. 28471345Sgshapiro CONFIG: Reject addresses of the form a!b if FEATURE(`nouucp', `r') 28571345Sgshapiro is used. Problem noted by Phil Homewood of Asia Online, 28671345Sgshapiro patch from Neil Rickert of Northern Illinois University. 28771345Sgshapiro CONFIG: Change the default DNS based blacklist server for 28873188Sgshapiro FEATURE(`dnsbl') to blackholes.mail-abuse.org. 28971345Sgshapiro CONFIG: Deal correctly with the 'C' flag in {daemon_flags}, i.e., 29071345Sgshapiro implicitly assume canonical host names. 29171345Sgshapiro CONFIG: Deal with "::" in IPv6 addresses for access_db. Based on 29271345Sgshapiro patch by Motonori Nakamura of Kyoto University. 29371345Sgshapiro CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of 29471345Sgshapiro Virginia Tech. 29571345Sgshapiro CONFIG: Pass the illegal header form <list:;> through untouched 29671345Sgshapiro instead of making it worse. Problem noted by Motonori 29771345Sgshapiro Nakamura of Kyoto University. 29871345Sgshapiro CONTRIB: Added buildvirtuser (see `perldoc contrib/buildvirtuser`). 29971345Sgshapiro CONTRIB: qtool.pl: An empty queue is not an error. Problem noted 30071345Sgshapiro by Jan Krueger of digitalanswers communications consulting 30171345Sgshapiro gmbh. 30271345Sgshapiro CONTRIB: domainmap.m4: Handle domains with '-' in them. From Mark 30371345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 30471345Sgshapiro DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4 30571345Sgshapiro variables into bldOS, bldREL, and bldARCH to prevent 30673188Sgshapiro namespace collisions. Problem noted by Motonori Nakamura 30771345Sgshapiro of Kyoto University. 30871345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 30971345Sgshapiro causes some changes in behavior and may break rmail for 31071345Sgshapiro installations where sendmail is actually a wrapper to 31171345Sgshapiro another MTA. The change will re-appear in a future 31271345Sgshapiro version. 31371345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 31471345Sgshapiro and SunOS 5.8. Requested by Jeff A. Earickson of Colby 31571345Sgshapiro College and John Beck of Sun Microsystems. 31671345Sgshapiro VACATION: Fix pattern matching for addresses to ignore. 31771345Sgshapiro VACATION: Don't reply to addresses of the form owner-* 31871345Sgshapiro or *-owner. 31971345Sgshapiro New Files: 32071345Sgshapiro cf/ostype/aix5.m4 32171345Sgshapiro contrib/buildvirtuser 32271345Sgshapiro devtools/OS/AIX.5.0 32371345Sgshapiro 32466494Sgshapiro8.11.1/8.11.1 2000/09/27 32566494Sgshapiro Fix SMTP EXPN command output if the address expands to a single 32666494Sgshapiro name.

Problem noted by Marc G. 35666494Sgshapiro Fournier of Acadia University. 35766494Sgshapiro If an LDAP search fails because the LDAP server went down, close 35866494Sgshapiro the map so subsequent searches reopen the map. If there are 35966494Sgshapiro multiple LDAP servers, the down server will be skipped and 36066494Sgshapiro one of the others may be able to take over. 36166494Sgshapiro Set the ${load_avg} macro to the current load average, not the 36266494Sgshapiro previous load average query result. 36366494Sgshapiro If a non-optional map used in a check_* ruleset can't be opened, 36466494Sgshapiro return a temporary failure to the remote SMTP client 36566494Sgshapiro instead of ignoring the map.

Problem noted by Damian Kuczynski of NIK. 42066494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 42166494Sgshapiro makemap to 'unmake' the map. 42266494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 42366494Sgshapiro sendmail. 42466494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 42566494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 42666494Sgshapiro Meteorological Institute. 42766494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 42866494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 42966494Sgshapiro dot as the only character on the line. 43066494Sgshapiro New Files: 43166494Sgshapiro cf/ostype/solaris8.m4 43266494Sgshapiro 43364562Sgshapiro8.11.0/8.11.0 2000/07/19 43464562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 43564562Sgshapiro (not the normal case), some operating systems will still 43664562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 43764562Sgshapiro to drop all of its privileges. If sendmail needs to drop 43864562Sgshapiro these privileges and the operating system doesn't set the 43964562Sgshapiro saved-uid as well, exit with an error. Problem noted by 44064562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 44164562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 44264562Sgshapiro it populates. It is possible that some broken 44364562Sgshapiro implementations of snprintf() exist that do not do this. 44464562Sgshapiro Systems in this category should compile with 44564562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 44664562Sgshapiro system and report broken implementations to 44764562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 44864562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 44964562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 45064562Sgshapiro Implementation influenced by the example programs of 45164562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 45264562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 45364562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 45464562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 45564562Sgshapiro cf/README and doc/op/op.*. 45664562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 45764562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 45864562Sgshapiro ${server_name}, and ${server_addr}. These are documented 45964562Sgshapiro in cf/README and doc/op/op.*. 46064562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 46164562Sgshapiro random data. 46264562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 46364562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 46464562Sgshapiro try to use STARTTLS despite the security problems. 46564562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 46664562Sgshapiro support encryption. Based on code contributed by Tim 46764562Sgshapiro Martin of CMU. 46864562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 46964562Sgshapiro strength factor. 47064562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 47164562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 47264562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 47364562Sgshapiro of CMU. 47464562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 47564562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 47664562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 47764562Sgshapiro Fix the default family selection for DaemonPortOptions. As 47864562Sgshapiro documented, unless a family is specified in a 47964562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 48064562Sgshapiro also the default if no DaemonPortOptions value is set. 48164562Sgshapiro Therefore, IPv6 users should configure additional sockets 48264562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 48364562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 48464562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 48564562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 48664562Sgshapiro the interface information for an outgoing connection. 48764562Sgshapiro Not doing so was creating a mismatch between the socket 48864562Sgshapiro family and address used in subsequent connections if the 48964562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 49064562Sgshapiro by John Beck of Sun Microsystems. 49164562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 49264562Sgshapiro family based on the IP address. ${if_family} is no longer 49364562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 49464562Sgshapiro of Sun Microsystems. 49564562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 49664562Sgshapiro macros for both the incoming interface address/family and 49764562Sgshapiro the outgoing interface address/family. In order for M=b 49864562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 49964562Sgshapiro the incoming information in the queue file for later 50064562Sgshapiro delivery attempts. 50164562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 50264562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 50364562Sgshapiro smoe.org. 50464562Sgshapiro Add more vigilance in checking for putc() errors on output streams 50564562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 50664562Sgshapiro noted by Graeme Hewson of Oracle. 50764562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 50864562Sgshapiro Problem noted by Ajay Matia. 50964562Sgshapiro Under certain circumstances, an address could be listed as deferred 51064562Sgshapiro but would be bounced back to the sender as failed to be 51164562Sgshapiro delivered when it really should have been queued. Problem 51264562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 51364562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 51464562Sgshapiro the SMTP transaction out of sync.

Problem noted by Neil Rickert 51964562Sgshapiro of Northern Illinois University. 52064562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 52164562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 52264562Sgshapiro Convert the free disk space shown in a control socket status query 52364562Sgshapiro to kilobyte units. 52464562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 52564562Sgshapiro looking up the hostname, requeue the message for a later 52664562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 52764562Sgshapiro Polytechnic. 52864562Sgshapiro Under the proper circumstances, failed connections would be recorded 52964562Sgshapiro as "Bad file number" instead of "Connection failed" in the 53064562Sgshapiro queue file and persistent host status. Problem noted by 53164562Sgshapiro Graeme Hewson of Oracle. 53264562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 53364562Sgshapiro within the hoststatus directory (e.g., lost+found). 53464562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 53564562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 53664562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 53764562Sgshapiro If a message data file can't be opened at delivery time, panic and 53864562Sgshapiro abort the attempt instead of delivering a message that 53964562Sgshapiro states "<<< No Message Collected >>>". 54064562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 54164562Sgshapiro restrictive.

Problem noted 54964562Sgshapiro by Valdis Kletnieks of Virginia Tech. 55064562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 55164562Sgshapiro only the first to open the connection is allowed to close 55264562Sgshapiro it so a later map close doesn't break the connection for 55364562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 55464562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 55564562Sgshapiro authentication. Patch from Rainer Schoepf of the 55664562Sgshapiro University of Mainz. 55764562Sgshapiro Provide workaround for inconsistent handling of data passed 55864562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 55964562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

This option and 81464562Sgshapiro its use is deprecated and will be removed from a future 81564562Sgshapiro version of sendmail. 81664562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 81764562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 81864562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 81964562Sgshapiro (IdS). 82064562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 82164562Sgshapiro a large number of files. See cf/README for more details. 82264562Sgshapiro The directory structure of the distribution has changed slightly 82364562Sgshapiro for easier code sharing among the programs. 82464562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 82564562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 82664562Sgshapiro which hold the client's authentication credentials, 82764562Sgshapiro the mechanism used for authentication, and the 82864562Sgshapiro authorization identity (i.e., the AUTH= parameter if 82964562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 83064562Sgshapiro On systems which use the Torek stdio library (all of the BSD 83164562Sgshapiro distributions), use memory-buffered files to reduce 83264562Sgshapiro file system overhead by not creating temporary files on 83364562Sgshapiro disk. Contributed by Exactis.com, Inc. 83464562Sgshapiro New option DataFileBufferSize to control the maximum size of a 83564562Sgshapiro memory-buffered data (df) file before a disk-based file is 83664562Sgshapiro used. Contributed by Exactis.com, Inc. 83764562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 83864562Sgshapiro memory-buffered transcript (xf) file before a disk-based 83964562Sgshapiro file is used. Contributed by Exactis.com, Inc. 84064562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 84164562Sgshapiro now listen on several different ports. Use: 84264562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 84364562Sgshapiro to run a Message Submission Agent (MSA); this is turned 84464562Sgshapiro on by default in m4-generated .cf files; it can be turned 84564562Sgshapiro off with FEATURE(`no_default_msa'). 84664562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 84764562Sgshapiro begin using RFC 2476 Message Submission for initial user 84864562Sgshapiro message submission. XUSR may disappear from a future release. 84964562Sgshapiro The new '-G' (relay (gateway) submission) command line option 85064562Sgshapiro indicates that the message being submitted from the command 85164562Sgshapiro line is for relaying, not initial submission. This means 85264562Sgshapiro the message will be rejected if the addresses are not fully 85364562Sgshapiro qualified and no canonicalization will be done. Future 85464562Sgshapiro releases may even reject improperly formed messages. 85564562Sgshapiro The '-U' (initial user submission) command line option is 85664562Sgshapiro deprecated and may be removed from a future release. 85764562Sgshapiro Mail user agents should begin using '-G' to indicate that 85864562Sgshapiro this is a relay submission (the inverse of -U). 85964562Sgshapiro The next release of sendmail will assume that any message submitted 86064562Sgshapiro from the command line is an initial user submission and act 86164562Sgshapiro accordingly. 86264562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 86364562Sgshapiro program or deliver to file as the owner of that file, the 86464562Sgshapiro address is marked as unsafe. This means if RunAsUser is 86564562Sgshapiro set, users won't be able to use programs or delivery to 86664562Sgshapiro files in their .forward files. Administrators can override 86764562Sgshapiro this by setting the DontBlameSendmail option to the new 86864562Sgshapiro setting NonRootSafeAddr. 86964562Sgshapiro Allow group or world writable directories if the sticky bit is set 87064562Sgshapiro on the directory and DontBlameSendmail is set to 87164562Sgshapiro TrustStickyBit.

To use multiple queues, supply 90464562Sgshapiro a QueueDirectory option value ending with an asterisk. For 90564562Sgshapiro example, /var/spool/mqueue/q* will use all of the 90664562Sgshapiro directories or symbolic links to directories beginning with 90764562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 90864562Sgshapiro mind, the queue directory structure should not be changed 90964562Sgshapiro while sendmail is running. Queue runs create a separate 91064562Sgshapiro process for running each queue unless the verbose flag is 91164562Sgshapiro given on a non-daemon queue run. New items are randomly 91264562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 91364562Sgshapiro Support different directories for qf, df, and xf queue files; if 91464562Sgshapiro subdirectories or symbolic links to directories of those names 91564562Sgshapiro exist in the queue directories, they are used for the 91664562Sgshapiro corresponding queue files. Keep in mind, the queue 91764562Sgshapiro directory structure should not be changed while sendmail is 91864562Sgshapiro running. Proposed by Mathias Koerber of Singapore 91964562Sgshapiro Telecommunications Ltd. 92064562Sgshapiro New queue file naming system which uses a filename guaranteed to be 92164562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 92264562Sgshapiro without fancy file system locking. Queued items can be 92364562Sgshapiro moved between queues easily. Contributed by Exactis.com, 92464562Sgshapiro Inc. 92564562Sgshapiro Messages which are undeliverable due to temporary address failures 92664562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 92764562Sgshapiro set.

Contributed by Exactis.com, Inc. 93064562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 93164562Sgshapiro avoids opening and reading each queue file when preparing 93264562Sgshapiro to run the queue.

This can be used with LMTP 94864562Sgshapiro local delivery agents which listen on a named socket. An 94964562Sgshapiro example mailer might be: 95064562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 95164562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 95264562Sgshapiro A=FILE /var/run/lmtpd 95364562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 95464562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 95564562Sgshapiro instead. 95664562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 95764562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 95864562Sgshapiro connections), IPC (which will be deprecated in a future 95964562Sgshapiro version), and FILE (for UNIX domain socket delivery). 96064562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 96164562Sgshapiro flags. 96264562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 96364562Sgshapiro body of the original message on delivery status 96464562Sgshapiro notifications. 96564562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 96664562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 96764562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 96864562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 96964562Sgshapiro Steve Schweinhart of America Online. 97064562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 97164562Sgshapiro not be set after rulesets are defined. Suggested by 97264562Sgshapiro Mitchell Blank Jr of Exec-PC. 97364562Sgshapiro Do not report temporary failure on delivery to files. In 97464562Sgshapiro interactive delivery mode, this would result in two SMTP 97564562Sgshapiro responses after the DATA command.

Problem noted by Nik 97864562Sgshapiro Conwell of Boston University. 97964562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 98064562Sgshapiro Curtis W. Hillegas of Princeton University. 98164562Sgshapiro Always bind to the LDAP server regardless of whether you are using 98264562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 98364562Sgshapiro @Home Network. 98464562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 98564562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 98664562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 98764562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 98864562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 98964562Sgshapiro similar to check_rcpt etc. 99064562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 99164562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 99264562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 99364562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 99464562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 99564562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 99664562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 99764562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 99864562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 99964562Sgshapiro the corresponding DSN parameter values. Proposed by 100064562Sgshapiro Mathias Herberts. 100164562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 100264562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 100364562Sgshapiro before the message has been collected, thereafter it holds 100464562Sgshapiro the message size as computed by sendmail (and can be used 100564562Sgshapiro in check_compat). 100664562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 100764562Sgshapiro sendmail is using instead of the value of the DeliveryMode 100864562Sgshapiro option. 100964562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 101064562Sgshapiro Drop explicit From: if same as what would be generated only if it is 101164562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 101264562Sgshapiro Write pid to file also if sendmail only processes the queue. 101364562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 101464562Sgshapiro Log "low on disk space" only when necessary. 101564562Sgshapiro New macro ${load_avg} can be used to check the current load average. 101664562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 101764562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 101864562Sgshapiro is set. 101964562Sgshapiro Flag -S for maps to specify the character which is substituted 102064562Sgshapiro for spaces (instead of the default given by O BlankSub). 102164562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 102264562Sgshapiro This flag is set by default for the host map. Based on a 102364562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 102464562Sgshapiro Open maps only on demand, not at startup. 102564562Sgshapiro Log warning about unsupported IP address families. 102664562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 102764562Sgshapiro of the sum of all headers. This can be used to prevent 102864562Sgshapiro a denial-of-service attack. 102964562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 103064562Sgshapiro headers and parameters within those headers. This option 103164562Sgshapiro is intended to protect mail user agents from buffer 103264562Sgshapiro overflow attacks. 103364562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 103464562Sgshapiro alias recursion. 103564562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 103664562Sgshapiro Map type syslog to log the key via syslogd. 103764562Sgshapiro Entries in the alias file can be continued by putting a backslash 103864562Sgshapiro directly before the newline. 103964562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 104064562Sgshapiro dead.letter file, formerly hardcoded to 104164562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 104264562Sgshapiro default), sendmail will not attempt to save to a 104364562Sgshapiro system-wide dead.letter file if it can not bounce the mail 104464562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 104564562Sgshapiro file as it has in the past when the dead.letter file 104664562Sgshapiro could not be opened. 104764562Sgshapiro New option PidFile to define the location of the pid file. The 104864562Sgshapiro value of this option is macro expanded. 104964562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 105064562Sgshapiro process title shown in 'ps' listings. 105164562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 105264562Sgshapiro (along with the already existing macros): 105364562Sgshapiro ${daemon_info} Daemon information, e.g. 105464562Sgshapiro SMTP+queueing@00:30:00 105564562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 105664562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 105764562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 105864562Sgshapiro ${daemon_port} Daemon port, e.g., 25 105964562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 106064562Sgshapiro New macros especially for virtual hosting: 106164562Sgshapiro ${if_name} hostname of interface of incoming connection. 106264562Sgshapiro ${if_addr} address of interface of incoming connection. 106364562Sgshapiro The latter is only set if the interface does not belong to the 106464562Sgshapiro loopback net. 106564562Sgshapiro If a message being accepted via a method other than SMTP and 106664562Sgshapiro would be rejected by a header check, do not send the message. 106764562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 106864562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 106964562Sgshapiro Provide header value as quoted string in the macro 107064562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 107164562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 107264562Sgshapiro The length of the header value is stored in ${hdrlen}. 107364562Sgshapiro H*: allows to specify a default ruleset for header checks. This 107464562Sgshapiro ruleset will only be called if the individual header does 107564562Sgshapiro not have its own ruleset assigned. Suggested by Jan 107664562Sgshapiro Krueger of Unix-AG of University of Hannover. 107764562Sgshapiro The name of the header field stored in ${hdr_name}. 107864562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 107964562Sgshapiro removed if the config file version is greater than or equal 108064562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 108164562Sgshapiro input "token (1)" but does not match "token". 108264562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 108364562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 108464562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 108564562Sgshapiro Ericsson. 108664562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 108764562Sgshapiro messages with 8-bit text in headers. Problem noted by 108864562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 108964562Sgshapiro of Ericsson. 109064562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 109164562Sgshapiro modified database map file. Problem noted by Chris Adams 109264562Sgshapiro of Renaissance Internet Services. 109364562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 109464562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 109564562Sgshapiro queue up the message instead of bouncing it. 109664562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 109764562Sgshapiro standard does not provide any indication of what to do when 109864562Sgshapiro something other than 250 is received. Based on a patch 109964562Sgshapiro from Steve Schweinhart of America Online. 110064562Sgshapiro New option TrustedUser allows to specify a user who can own 110164562Sgshapiro important files instead of root. This requires HASFCHOWN. 110264562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 110364562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 110464562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 110564562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 110664562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 110764562Sgshapiro $? tests also whether the macro is non-null. 110864562Sgshapiro Print an error message if a mailer definition contains an invalid 110964562Sgshapiro equate name. 111064562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 111164562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 111264562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 111364562Sgshapiro mailer to return after sending all data to it. 111464562Sgshapiro Only free memory from the process list when adding a new process 111564562Sgshapiro into a previously filled slot. Previously, the memory was 111664562Sgshapiro freed at removal time. Since removal can happen in a 111764562Sgshapiro signal handler, this may leave the memory map in an 111864562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 111964562Sgshapiro David Cooley of Colby College. 112064562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 112164562Sgshapiro local users in the passwd file. The UserDB code has 112264562Sgshapiro already decided the message will be passed to another host 112364562Sgshapiro for processing. Fix from Tony Landells of Burdett 112464562Sgshapiro Buckeridge Young Limited. 112564562Sgshapiro Support LDAP authorization via either a file containing the 112664562Sgshapiro password or Kerberos V4 using the new map options 112764562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 112864562Sgshapiro distinguished_name is who to login as. The method can be 112964562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 113064562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 113164562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 113264562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 113364562Sgshapiro of Stanford University. 113464562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 113564562Sgshapiro deprecated and will be removed in a future version. 113664562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 113764562Sgshapiro and the map has the column delimiter set, it turns that 113864562Sgshapiro response into a delimiter separated string. The LDAP map 113964562Sgshapiro will traverse multiple entries as well. LDAP alias maps 114064562Sgshapiro automatically set the column delimiter to the comma. 114164562Sgshapiro Based on patch from Booker Bense of Stanford University and 114264562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 114364562Sgshapiro Support return of multiple values for a single LDAP lookup. The 114464562Sgshapiro values to be returned should be in a comma separated string. 114564562Sgshapiro For example, `-v "email,emailother"'. Patch from 114664562Sgshapiro Curtis W. Hillegas of Princeton University. 114764562Sgshapiro Allow the use of LDAP for alias maps. 114864562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 114964562Sgshapiro attributes found in the match will be returned. 115064562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 115164562Sgshapiro breaking up a single entry into multiple entries. This is 115264562Sgshapiro needed for LDAP alias file specifications to allow for 115364562Sgshapiro comma separated key and value strings. 115464562Sgshapiro Keep connections to LDAP server open instead of opening and closing 115564562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 115664562Sgshapiro connections such that multiple maps which use the same 115764562Sgshapiro host, port, bind DN, and authentication will only result in 115864562Sgshapiro a single connection to that host. 115964562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 116064562Sgshapiro Be more careful about checking for errors and freeing memory on 116164562Sgshapiro LDAP lookups. 116264562Sgshapiro Use asynchronous LDAP searches to save memory and network 116364562Sgshapiro resources. 116464562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 116564562Sgshapiro Increase portability to the Netscape LDAP libraries. 116664562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 116764562Sgshapiro replaced with the literal contents of the map lookup key -- 116864562Sgshapiro note that this means a lookup can be done using the LDAP 116964562Sgshapiro special characters. The new '%0' token can be used instead 117064562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 117164562Sgshapiro For example, if the LDAP map specification contains '-k 117264562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 117364562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 117464562Sgshapiro user attribute. Instead, if the LDAP map specification 117564562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 117664562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 117764562Sgshapiro with the name "*". 117864562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 117964562Sgshapiro more than one is returned, it is equivalent to no records 118064562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 118164562Sgshapiro alias dereference option; "-Z size" limits the number of 118264562Sgshapiro matches to return. 118364562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 118464562Sgshapiro LDAP maps. The value should only contain LDAP specific 118564562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 118664562Sgshapiro settings will be used for all LDAP maps unless they are 118764562Sgshapiro specified in the individual map specification ('K' 118864562Sgshapiro command). This option should be set before any LDAP maps 118964562Sgshapiro are defined. 119064562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 119164562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 119264562Sgshapiro Tech. 119364562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 119464562Sgshapiro particular, class entries get much smaller, which can be 119564562Sgshapiro important if you have large classes. 119664562Sgshapiro On network-related temporary failures, record the hostname which 119764562Sgshapiro gave error in the queued status message. Requested by 119864562Sgshapiro Ulrich Windl of the Universitat Regensburg. 119964562Sgshapiro Add new F=% mailer flag to allow for a store and forward 120064562Sgshapiro configuration. Mailers which have this flag will not attempt 120171345Sgshapiro delivery on initial receipt of a message or on queue runs 120264562Sgshapiro unless the queued message is selected using one of the 120364562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 120464562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 120564562Sgshapiro New option ControlSocketName which, when set, creates a daemon 120664562Sgshapiro control socket. This socket allows an external program to 120764562Sgshapiro control and query status from the running sendmail daemon 120864562Sgshapiro via a named socket, similar to the ctlinnd interface to the 120964562Sgshapiro INN news server. Access to this interface is controlled by 121064562Sgshapiro the UNIX file permissions on the named socket on most UNIX 121164562Sgshapiro systems (see sendmail/README for more information). An 121264562Sgshapiro example control program is provided as contrib/smcontrol.pl. 121364562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 121464562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 121564562Sgshapiro number of processors online on the system (if that can be 121664562Sgshapiro determined). For single processor machines, this change 121764562Sgshapiro has no effect. 121864562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 121964562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 122064562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 122164562Sgshapiro Motonori Nakamura of Kyoto University. 122264562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 122364562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 122464562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 122564562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 122664562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 122764562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 122864562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 122964562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 123064562Sgshapiro connection-based denial of service attacks. 123164562Sgshapiro Log basic information about authenticated connections at LogLevel 123264562Sgshapiro 10 or higher. 123364562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 123464562Sgshapiro information (from= syslog line). 123564562Sgshapiro Log the DSN code for each recipient if one is available as a new 123664562Sgshapiro equate (dsn=). 123764562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 123864562Sgshapiro New "ph" map for performing ph queries in rulesets.

Problem noted by Kari Hurtta of the 124464562Sgshapiro Finnish Meteorological Institute. 124564562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 124664562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 124764562Sgshapiro When a forward file points to an alias which runs a program, run 124864562Sgshapiro the program as the default user and the default group, not 124964562Sgshapiro the forward file user. This change also assures the 125064562Sgshapiro :include: directives in aliases are also processed using 125164562Sgshapiro the default user and group. Problem noted by Sergiu 125264562Sgshapiro Popovici of DNT Romania. 125364562Sgshapiro Prevent attempts to save a dead.letter file for a user with 125464562Sgshapiro no home directory (/no/such/directory). Problem noted by 125564562Sgshapiro Michael Brown of Finnigan FT/MS. 125664562Sgshapiro Include message delay and number of tries when logging that a 125764562Sgshapiro message has been completely delivered (LogLevel of 10 or 125864562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 125964562Sgshapiro Log the sender of a message even if none of the recipients were 126064562Sgshapiro accepted. If some of the recipients were rejected, it is 126164562Sgshapiro helpful to know the sender of the message. 126264562Sgshapiro Check the root directory (/) when checking a path for safety. 126364562Sgshapiro Problem noted by John Beck of Sun Microsystems. 126464562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 126564562Sgshapiro interactive and delivering to an alias which resolves to 126664562Sgshapiro multiple files. 126764562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 126864562Sgshapiro greater (see below); the help function doesn't print the 126964562Sgshapiro version of sendmail any longer, instead it is placed in 127064562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 127164562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 127264562Sgshapiro skipped and a version line (#vers) is introduced. The 127364562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 127464562Sgshapiro version is found, a warning is logged. The '#vers' 127564562Sgshapiro directive should be placed at the top of the help file. 127664562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 127764562Sgshapiro disk succeeded. Suggested by Nick Christenson. 127864562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 127964562Sgshapiro length before the attempt. 128064562Sgshapiro If a forward points to a filename for delivery, change to the 128164562Sgshapiro user's uid before checking permissions on the file. This 128264562Sgshapiro allows delivery to files on NFS mounted directories where 128364562Sgshapiro root is remapped to nobody. Problem noted by Harald 128464562Sgshapiro Daeubler of Universitaet Ulm. 128564562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 128664562Sgshapiro host status files, not all files. 128764562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 128864562Sgshapiro in the queue file for the message and set when delivery 128964562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 129064562Sgshapiro Wonderworks Inc. 129164562Sgshapiro Add support for storing information between rulesets using the new 129264562Sgshapiro macro map class. This can be used to store information 129364562Sgshapiro between queue runs as well using $={persistentMacros}. 129464562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 129564562Sgshapiro of Hannover. 129664562Sgshapiro New map class arith to allow for computations in rules. The 129764562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 129864562Sgshapiro as key. The two operands are specified as arguments; the 129964562Sgshapiro lookup returns the result of the computation. For example, 130064562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 130164562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 130264562Sgshapiro Add new syntax for header declarations which decide whether to 130364562Sgshapiro include the header based on a macro rather than a mailer 130464562Sgshapiro flag: 130564562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 130664562Sgshapiro This should be used along with $={persistentMacros}. 130764562Sgshapiro It can be used for adding headers to a message based on 130864562Sgshapiro the results of check_* and header check rulesets. 130964562Sgshapiro Allow new named config file rule check_eoh which is called after 131064562Sgshapiro all of the headers have been collected. The input to the 131164562Sgshapiro ruleset the number of headers and the size of all of the 131264562Sgshapiro headers in bytes separated by $|. This ruleset along with 131364562Sgshapiro the macro storage map can be used to correlate information 131464562Sgshapiro gathered between headers and to check for missing headers. 131564562Sgshapiro See cf/README or doc/op/op.ps for an example. 131664562Sgshapiro Change the default for the MeToo option to True to correspond 131764562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 131864562Sgshapiro option is deprecated and will be removed from a future 131964562Sgshapiro version. 132064562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 132164562Sgshapiro Change the sendmail binary default for SuperSafe to True. 132264562Sgshapiro Display ruleset names in debug and address test mode output 132364562Sgshapiro if referencing a named ruleset. 132464562Sgshapiro New mailer equate m= which will limit the number of messages 132564562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 132664562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 132764562Sgshapiro using it to sort. Now all the same domains are really run 132864562Sgshapiro through the queue together. If they have the same MX host, 132964562Sgshapiro then they will have a much better opportunity to use the 133064562Sgshapiro connection cache if available. This should be a reasonable 133164562Sgshapiro performance improvement. Patch from Randall Winchester of 133264562Sgshapiro the University of Maryland. 133364562Sgshapiro If a message is rejected by a header check ruleset, log who would 133464562Sgshapiro have received the message if it had not been rejected. 133564562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 133664562Sgshapiro queue immediately. No delivery attempt is made. 133764562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 133864562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 133964562Sgshapiro COMMANDS). 134064562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 134164562Sgshapiro but for outgoing connections. 134264562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 134364562Sgshapiro error messages and logging) and Modifiers, i.e. 134464562Sgshapiro a require authentication 134564562Sgshapiro b bind to interface through which mail has 134664562Sgshapiro been received 134764562Sgshapiro c perform hostname canonification 134864562Sgshapiro f require fully qualified hostname 134964562Sgshapiro h use name of interface for outgoing HELO 135064562Sgshapiro command 135164562Sgshapiro C don't perform hostname canonification 135264562Sgshapiro E disallow ETRN (see RFC 2476) 135364562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 135464562Sgshapiro h use name of interface for HELO command 135564562Sgshapiro The version number for queue files (qf) has been incremented to 4. 135664562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 135764562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 135864562Sgshapiro Institutes of Health. 135964562Sgshapiro If a mailer dies, print the status in decimal instead of octal 136064562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 136164562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 136264562Sgshapiro Move message priority from sender to recipient logging. Suggested by 136364562Sgshapiro Ulrich Windl of the Universitat Regensburg. 136464562Sgshapiro Add support for Berkeley DB 3.X. 136564562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 136664562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 136764562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 136864562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 136964562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 137064562Sgshapiro sub-options is set on the command line. Problem noted by 137164562Sgshapiro Graeme Hewson of Oracle. 137264562Sgshapiro Randomize equal preference MX records each time delivery is 137364562Sgshapiro attempted via a new connection to a host instead of once per 137464562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 137564562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 137664562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 137764562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 137864562Sgshapiro to hosts which have dynamically assigned names. 137964562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 138064562Sgshapiro the bounce for the same reason. If the body is not 8-bit 138164562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 138264562Sgshapiro not be included in the bounce. Problem noted by Valdis 138364562Sgshapiro Kletnieks of Virginia Tech. 138464562Sgshapiro The timeout for sending a message via SMTP has been changed from 138564562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 138664562Sgshapiro simply checks for progress on sending data every 5 minutes. 138764562Sgshapiro This will detect the inability to send information quicker 138864562Sgshapiro and reduce the number of processes simply waiting to 138964562Sgshapiro timeout. 139064562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 139164562Sgshapiro interface address structure when loading the system network 139264562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 139364562Sgshapiro Nanoteq. 139464562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 139564562Sgshapiro indicates the number of interfaces to read when probing 139664562Sgshapiro for hostnames and IP addresses for class w ($=w). The 139764562Sgshapiro default value is 512. Based on idea from Reinier 139864562Sgshapiro Bezuidenhout of Nanoteq. 139964562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 140064562Sgshapiro on load average. 140164562Sgshapiro Allow ruleset 0 to have a name.

Prindeville of Enteka Enterprise Technology 175464562Sgshapiro Services. 175564562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 175664562Sgshapiro names. Problem noted by Randall Winchester of Swales 175764562Sgshapiro Aerospace. 175864562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 175964562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 176064562Sgshapiro University and Brian Candler. 176164562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 176264562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 176364562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 176464562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 176564562Sgshapiro Institute. 176664562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 176764562Sgshapiro i.e., to set, add, or delete flags. 176864562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 176964562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 177064562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 177164562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 177264562Sgshapiro after check_rcpt and allows for exceptions from the checks. 177364562Sgshapiro CONFIG: Map declarations have been moved into their associated 177464562Sgshapiro feature files to allow greater flexibility in use of 177564562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 177664562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 177764562Sgshapiro line string for the local mailer. Requested by Il Oh of 177864562Sgshapiro Willamette Industries, Inc. 177964562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 178064562Sgshapiro converted to <user@d> 178164562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 178264562Sgshapiro Sun's older, broken configuration files. 178364562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 178464562Sgshapiro normal configuration, allowing anti-spam checks to be 178564562Sgshapiro performed. 178664562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 178764562Sgshapiro ${client_name} can't be resolved just temporarily. 178864562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 178964562Sgshapiro Institute. 179064562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 179164562Sgshapiro be accessed by their numbers). 179264562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 179364562Sgshapiro which describes whether to disallow "!" in the local part 179464562Sgshapiro of an address. 179564562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 179664562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 179764562Sgshapiro set. If the ruleset returns a mailer, the appropriate 179864562Sgshapiro action is taken, otherwise the returned tokens are ignored. 179964562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 180064562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 180164562Sgshapiro The latter is kept around for backward compatibility. 180264562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 180364562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 180464562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 180564562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 180664562Sgshapiro line.

Problem noted by Ezequiel H. Panepucci of 183164562Sgshapiro Yale University. 183264562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 183364562Sgshapiro be used for building. 183464562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 183564562Sgshapiro used for a fresh build. 183664562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 183764562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 183864562Sgshapiro ranlib. 183964562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 184064562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 184164562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 184264562Sgshapiro building of the man pages when defined. Suggested by Bryan 184364562Sgshapiro Costales. 184464562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 184564562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 184664562Sgshapiro installation of the sendmail helpfile and statistics file 184764562Sgshapiro respectively. Suggested by Bryan Costales. 184864562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 184964562Sgshapiro of Siemens Business Services. 185064562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 185164562Sgshapiro stdio library. The new buffered file I/O depends on the 185264562Sgshapiro Torek stdio library. This option can be either portable or 185364562Sgshapiro torek. 185464562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 185564562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 185664562Sgshapiro They should contain the C source files for the object files 185764562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 185864562Sgshapiro will be passed to the 'make depend' stage of compilation. 185964562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 186064562Sgshapiro in the sendmail distribution. Each has the form 186164562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 186264562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 186364562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 186464562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 186564562Sgshapiro building the distribution, but documentation on the changes 186664562Sgshapiro are in devtools/README. 186764562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 186864562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 186964562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 187064562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 187164562Sgshapiro new variable which identifies the root of the source 187264562Sgshapiro directories for all of the programs in the distribution. 187364562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 187464562Sgshapiro time. They can both still be overridden by setting the m4 187564562Sgshapiro macro. 187664562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 187764562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 187864562Sgshapiro build configurations, and places objects in obj.prefix.*/. 187964562Sgshapiro Complains as 'Build -f file' does for existing object 188064562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 188164562Sgshapiro Corporation. 188264562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 188364562Sgshapiro manual pages in the directory tree specified by 188464562Sgshapiro confMANROOTMAN. 188564562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 188664562Sgshapiro preformatted pages from the distribution. The new variable 188764562Sgshapiro confCOPY specifies the copying program. 188864562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 188964562Sgshapiro question. Suggested by Terry Lambert of Whistle 189064562Sgshapiro Communications. 189164562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 189264562Sgshapiro of the installed statistics and help files, respectively. 189364562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 189464562Sgshapiro operating system identity. Problem noted by Erik 189564562Sgshapiro Wachtenheim of Dartmouth College. 189664562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 189764562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 189864562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 189964562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 190064562Sgshapiro how to strip binaries. These are used by the new 190164562Sgshapiro install-strip target. 190264562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 190364562Sgshapiro the others (if it exists). 190464562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 190564562Sgshapiro then the default ones. 190680785Sgshapiro MAIL.LOCAL: Will not be installed set-user-id root. To use mail.local 190764562Sgshapiro as local delivery agent without LMTP mode, use 190864562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 190964562Sgshapiro to set the S flag. 191064562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 191164562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 191264562Sgshapiro Northern Illinois University. 191364562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 191464562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 191564562Sgshapiro the Finnish Meteorological Institute. 191664562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 191764562Sgshapiro MAILLOCK when compiling. Also requires linking with 191864562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 191964562Sgshapiro University. 192064562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 192164562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 192264562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 192364562Sgshapiro University. 192464562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 192564562Sgshapiro structure to the beginning of the program. This ensures that 192664562Sgshapiro the getservbyname() is done before any seteuid to a possibly 192764562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 192864562Sgshapiro on a Solaris system, this avoids syslog messages such as, 192964562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 193064562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 193164562Sgshapiro University. 193264562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 193364562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 193464562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 193564562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 193664562Sgshapiro characters (in LMTP mode), mail.local split the incoming 193764562Sgshapiro line up into 2046-character output lines (excluding the 193864562Sgshapiro newline). If an input line was 2047 characters long 193964562Sgshapiro (excluding CR-LF) and the last character was a '.', 194064562Sgshapiro mail.local saw it as the end of input, transfered it to the 194164562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 194264562Sgshapiro If the message was much longer, both sendmail and 194364562Sgshapiro mail.local would deadlock waiting for each other to read 194464562Sgshapiro what they have written. Problem noted by Peter Jeremy of 194564562Sgshapiro Alcatel Australia Limited. 194664562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 194764562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 194864562Sgshapiro Neil Rickert of Northern Illinois University. 194964562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 195064562Sgshapiro timeout to avoid starvation. 195164562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 195264562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 195364562Sgshapiro Infinite Monkeys & Co. 195464562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 195564562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 195664562Sgshapiro printed in a machine readable fashion and the stats file 195764562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 195864562Sgshapiro of Maryland. 195964562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 196064562Sgshapiro generated maps to the TrustedUser as specified in the 196164562Sgshapiro sendmail configuration file. 196264562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 196364562Sgshapiro configuration file to use for finding the TrustedUser 196464562Sgshapiro option. 196564562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database.

From Graeme Hewson of Oracle 197464562Sgshapiro Corporation UK. 197564562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 197664562Sgshapiro (e.g., sendmail would not drop root privileges if the 197764562Sgshapiro option was specified on the command line). Problem noted 197864562Sgshapiro by Todd C. Miller of Courtesan Consulting. 197964562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 198064562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 198164562Sgshapiro Institute for Global Communications. 198264562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 198364562Sgshapiro alias file(s) if the -f option is not used. Patch from 198464562Sgshapiro John Beck of Sun Microsystems. 198564562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 198664562Sgshapiro configuration file to use for finding alias file(s).

Sites 243638032Speter which need the ability to override security can use the 243738032Speter DontBlameSendmail option. See the README file for more 243838032Speter information. 243938032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 244038032Speter if maps or alias files are in world writable directories. 244138032Speter This fixes the change added to 8.8.6 to prevent links in these 244238032Speter world writable directories. 244338032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 244438032Speter it is in a world writable directory. 244538032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 244638032Speter tty it may be able to push bytes back to the senders input. 244738032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 245638032Speter reverts back to the old behavior of using uid 1 and gid 1. 245738032Speter This is a security problem for Linux which has chosen that 245838032Speter uid and gid for user bin instead of daemon. If DefaultUser 245938032Speter is set in the configuration file, that value overrides this 246038032Speter default. 246180785Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-id binaries 246238032Speter interfered with setting an alternate group id for the 246338032Speter RunAsUser option.

After this number is reached, sendmail 250738032Speter starts returning "452 Too many recipients" to all RCPT 250838032Speter commands. This can be used to limit the number of recipients 250938032Speter per envelope (in particular, to discourage use of the server 251038032Speter for spamming). Note: a better approach is to restrict 251138032Speter relaying entirely. 251238032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 251338032Speter to ldapx map and added timeout for ldap_open call to 251438032Speter avoid hanging sendmail in the event of hung LDAP servers. 251538032Speter Patch from Booker Bense of Stanford University. 251638032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 253938032Speter of Procter & Gamble. 254038032Speter New DontBlameSendmail option. This option allows administrators to 254138032Speter bypass some of sendmail's file security checks at the expense 254238032Speter of system security. This should only be used if you are 254338032Speter absolutely sure you know the consequences.

In particular, if you 257838032Speter have lots of virtual interfaces, this option will speed up 257938032Speter startup. However, unless you make other arrangements, mail 258038032Speter sent to those addresses will be bounced. 258138032Speter Automatically create alias databases if they don't exist and 258238032Speter AutoRebuildAliases is set. 258338032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 258438032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 258538032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 258638032Speter When determining the client host name ($&{client_name} macro), do 258738032Speter a forward (A) DNS lookup on the result of the PTR lookup 258838032Speter and compare results. If they differ or if the PTR lookup 258938032Speter fails, &{client_name} will contain the IP address 259064562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 259138032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 259238032Speter (i.e, it is like -ax for the temporary failure case, in 259338032Speter contrast to the success case). 259438032Speter New syntax to do limited checking of header syntax. A config line 259538032Speter of the form: 259638032Speter HHeader: $>Ruleset 259738032Speter causes the indicated Ruleset to be invoked on the Header 259838032Speter when read. This ruleset works like the check_* rulesets -- 259938032Speter that is, it can reject mail on the basis of the contents. 260038032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 260138032Speter from hiding their connection information in Received: 260238032Speter headers. 260338032Speter When SingleThreadDelivery is active, deliveries to locked hosts 260438032Speter are skipped. This will cause the delivering process to 260538032Speter try the next MX host or queue the message if no other MX 260638032Speter hosts are available. Suggested by Alexander Litvin. 260738032Speter The [FILE] mailer type now delivers to the file specified in the 260838032Speter A= equate of the mailer definition instead of $u. It also 260938032Speter obeys all of the F= mailer flags such as the MIME 261038032Speter 7/8 bit conversion flags. This is useful for defining 261138032Speter a mailer which delivers to the same file regardless of the 261264562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 261338032Speter Do not assume the identity of a remote connection is root@localhost 261438032Speter if the remote connection closes the socket before the 261538032Speter remote identity can be queried. 261638032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 261738032Speter Some mailers, including procmail, require that the real 261838032Speter uid is left unchanged by sendmail. Problem noted by Per 261938032Speter Hedeland of Ericsson. 262038032Speter No longer is the src/obj*/Makefile selected from a large list -- it 262138032Speter is now generated using the information in BuildTools/OS/ -- 262238032Speter some of the details are determined dynamically via 262338032Speter BuildTools/bin/configure.sh. 262438032Speter The other programs in the sendmail distribution -- mail.local, 262538032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 262638032Speter the new Build method which creates an operating system 262738032Speter specific Makefile using the information in BuildTools. 262838032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 262938032Speter a failure on one message won't affect future messages to the 263038032Speter same host). This is necessary if the remote host sends 263138032Speter a 451 error if the domain of the sender does not resolve 263238032Speter as is common in anti-spam configurations. Problem noted 263338032Speter by Mitchell Blank Jr of Exec-PC. 263438032Speter New "discard" mailer for check_* rulesets and header checking 263538032Speter rulesets. If one of the above rulesets resolves to the 263638032Speter $#discard mailer, the commands will be accepted but the 263738032Speter message will be completely discarded after it is accepting. 263838032Speter This means that even if only one of the recipients 263938032Speter resolves to the $#discard mailer, none of the recipients 264038032Speter will receive the mail. Suggested by Brian Kantor. 264138032Speter All but the last cloned envelope of a split envelope were queued 264238032Speter instead of being delivered.

Suggested by Scott 265938032Speter Gifford of The Internet Ramp. 266038032Speter Sendmail would get a segmentation fault if a mailer exited with an 266138032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 266238032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 266338032Speter Institute. 266438032Speter Separate snprintf/vsnprintf routines into separate file for use by 266538032Speter mail.local. 266638032Speter Allow multiple map lookups on right hand side, e.g., 266738032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 266838032Speter Christophe Wolfhugel of the Pasteur Institute. 266938032Speter Properly generate success DSN messages if requested for aliases 267038032Speter which have owner- aliases.

Patch from 274638032Speter Robert Harker of Harker Systems. 274738032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 274838032Speter directory for certain programs. 274938032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 275038032Speter local mail delivery. By the default, /usr/libexec/mail.local 275138032Speter is used. This is expected to be the mail.local shipped 275238032Speter with 8.9 which is LMTP capable. The path is based on the 275338032Speter new confEBINDIR m4 variable. 275438032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 275538032Speter FEATURE(smrsh). Note that this changes the default from 275638032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 275738032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 275838032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 275938032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 276038032Speter the user to setup different .forward files for 276138032Speter user+detail addressing. 276238032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 276338032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 276438032Speter DontProbeInterfaces, and DontBlameSendmail options. 276538032Speter CONFIG: by default do not allow relaying (that is, accepting mail 276638032Speter from outside your domain and sending it to another host 276738032Speter outside your domain). 276838032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 276938032Speter any site to any site. 277038032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 277138032Speter domain as defined by the 'm' class ($=m) to relay. 277238032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 277338032Speter the MX records of the host portion of an incoming recipient. 277438032Speter CONFIG: new FEATURE(access_db) which turns on the access database 277577349Sgshapiro feature. This database gives you the ability to allow 277638032Speter or refuse to accept mail from specified domains for 277738032Speter administrative reasons. By default, names that are listed 277838032Speter as "OK" in the access db are domain names, not host names. 277938032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 278038032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 278138032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 278238032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 278338032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 278438032Speter of FEATURE(access_db) and class 'R' to lookup individual 278538032Speter host names only. 278638032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 278738032Speter using % addressing is used, e.g. user%site@othersite, 278838032Speter and othersite is in class 'R', the check_rcpt ruleset 278938032Speter will strip @othersite and recheck user@site for relaying. 279038032Speter This feature changes that behavior. It should not be 279138032Speter needed for most installations. 279238032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 279338032Speter domain portion of the mail sender is a local host. This 279438032Speter should only be used if absolutely necessary as it opens 279538032Speter a window for spammers. Patch from Randall S. Winchester of 279638032Speter the University of Maryland. 279738032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 279838032Speter block incoming mail destined for certain recipient 279938032Speter usernames, hostnames, or addresses. 280038032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 280138032Speter refused if the host part of the argument to MAIL FROM: cannot 280238032Speter be located in the host name service (e.g., DNS). 280338032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 280438032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 280538032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 280638032Speter MAIL FROM: senders which do not include a domain. 280738032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 280838032Speter Realtime Blackhole List. You can specify the RBL name 280938032Speter server to contact by specifying it as an optional argument. 281038032Speter The default is rbl.maps.vix.com. For details, see 281138032Speter http://maps.vix.com/rbl/. 281238032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 281338032Speter Local_check_rcpt from check_relay, check_mail, and 281438032Speter check_rcpt. Users with local rulesets should place the 281538032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 281638032Speter returns $#OK, the message is accepted. If the ruleset 281738032Speter returns a mailer, the appropriate action is taken, else 281838032Speter the return of the ruleset is ignored. 281938032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 282038032Speter default to support file, :include:, and program deliveries. 282138032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 282238032Speter pick the proper default value. See the SECURITY note 282338032Speter above for more information. 282438032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 282538032Speter no-op. Patch from Kari Hurtta of the Finnish 282638032Speter Meteorological Institute. 282738032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 282838032Speter daemon since DEC's /bin/mail will drop the envelope 282938032Speter sender if run as mailnull. See the Digital UNIX section 283038032Speter of src/README for more information. Problem noted by 283138032Speter Kari Hurtta of the Finnish Meteorological Institute. 283238032Speter CONFIG: .cf files are now stored in the same directory with the 283338032Speter .mc files instead of in the obj directory. 283464562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 283538032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 283638032Speter setting SingleLineFromHeader, AllowBogusHELO, and 283738032Speter MustQuoteChars respectively. 283838032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.

Problem noted by Kari Hurtta of the Finnish 295638032Speter Meteorological Institute. 295738032Speter If /usr/tmp/dead.letter already existed, sendmail could not 295838032Speter add additional bounces to it. Problem noted by Thomas J. 295938032Speter Arseneault of SRI International. 296038032Speter If an SMTP mailer used a non-standard port number for the outgoing 296138032Speter connection, it would be displayed incorrectly in verbose mode. 296238032Speter Problem noted by John Kennedy of Cal State University, Chico. 296338032Speter Log the ETRN parameter specified by the client before altering them 296438032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 296538032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 296638032Speter User unknown with bogus delay= values. Change them to log 296738032Speter the same as compliant addresses. Problem noted by Kari E. 296838032Speter Hurtta of the Finnish Meteorological Institute. 296938032Speter Ignore the debug resolver option unless using sendmail debug trace 297038032Speter option for resolver. Problem noted by Greg Nichols of Wind 297138032Speter River Systems. 297238032Speter If SingleThreadDelivery was enabled and the remote server returned a 297338032Speter protocol error on the DATA command, the connection would be 297438032Speter closed but the persistent host status file would not be 297538032Speter unlocked so other sendmail processes could not deliver to 297638032Speter that host. Problem noted by Peter Wemm of DIALix. 297738032Speter If queueing up a message due to an expensive mailer, don't increment 297838032Speter the number of delivery attempts or set the last delivery 297938032Speter attempt time so the message will be delivered on the next 298038032Speter queue run regardless of MinQueueAge. Problem noted by 298138032Speter Brian J. Coan of the Institute for Global Communications. 298238032Speter Authentication warnings of "Processed from queue _directory_" and 298338032Speter "Processed by _username_ with -C _filename_" would be logged 298438032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 298538032Speter of the Finnish Meteorological Institute. 298638032Speter Use a better heuristic for detecting GDBM. 298738032Speter Log null connections on dropped connections. Problem noted by 298838032Speter Jon Lewis of Florida Digital Turnpike. 298938032Speter If class dbm maps are rebuilt, sendmail will now detect this and 299038032Speter reopen the map. Previously, they could give stale 299138032Speter results during a single message processing (but would 299238032Speter recover when the next message was received). Fix from 299338032Speter Joe Pruett of Q7 Enterprises. 299438032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 299538032Speter requests. Problem noted by Kari E. Hurtta of the 299638032Speter Finnish Meteorological Institute. 299738032Speter Do not send a bounce message back to the sender regarding bad 299838032Speter recipients if the SMTP connection is dropped before the 299938032Speter message is accepted. Problem noted by Kari E. Hurtta of the 300038032Speter Finnish Meteorological Institute. 300138032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 300238032Speter sendmail via a UNIX pipe. This will allow rulesets using 300338032Speter $&{client_name} to process without sending the string through 300438032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 300538032Speter A combination of deferred delivery mode, a double bounce situation, 300638032Speter and the inability to save a bounce message to 300738032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 300838032Speter to postmaster but not remove the offending envelope from the 300938032Speter queue causing it to create a new bounce message each time the 301038032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 301138032Speter Associates. 301238032Speter Remove newlines from hostname information returned via DNS. There are 301338032Speter no known security implications of newlines in hostnames as 301438032Speter sendmail filters newlines in all vital areas; however, this 301538032Speter could cause confusing error messages. 301638032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 301738032Speter rejected if any of the specified addresses were bad. This 301838032Speter behavior was modified to only reject the bad addresses and not 301938032Speter the entire message. Problem noted by Jozsef Hollosi of 302038032Speter SuperNet, Inc. 302138032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 302238032Speter Bryan Costales of InfoBeat, Inc. 302338032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 302438032Speter mailers. Problem noted by Kari E. Hurtta of the 302538032Speter Finnish Meteorological Institute. 302638032Speter An error in calculating the available space in the list of addresses 302738032Speter for logging deliveries could cause an address to be silently 302838032Speter dropped. 302938032Speter Include the initial user environment if sendmail is restarted via 303038032Speter a HUP signal. This will give room for the process title. 303138032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 303238032Speter Mail could be delivered without a body if the machine does not 303338032Speter support flock locking and runs out of processes during 303438032Speter delivery. Fix from Chuck Lever of the University of Michigan. 303538032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 303638032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 303738032Speter Institute. 303838032Speter Make sure non-rebuildable database maps are opened before the 303964562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 304038032Speter are needed for verifying the left hand side of the aliases. 304138032Speter Problem noted by Lloyd Parkes of Victoria University. 304238032Speter Make sure sender RFC822 source route addresses are alias expanded for 304338032Speter bounce messages. Problem noted by Juergen Georgi of 304438032Speter RUS University of Stuttgart. 304538032Speter Minor lint fixes. 304638032Speter Return a temporary error instead of a permanent error if an LDAP map 304738032Speter search returns an error. This will allow sequenced maps which 304838032Speter use other LDAP servers to be checked. Fix from Booker Bense 304938032Speter of Stanford University. 305038032Speter When automatically converting from quoted printable to 8bit text do 305138032Speter not pad bare linefeeds with a space. Problem noted by Theo 305238032Speter Nolte of the University of Technology Aachen, Germany. 305338032Speter Portability: 305438032Speter Non-standard C compilers may have had a problem compiling 305538032Speter conf.c due to a standard C external declaration of 305638032Speter setproctitle(). Problem noted by Ted Roberts of 305738032Speter Electronic Data Systems. 305838032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 305938032Speter Jagielski of jaguNET Access Services. 306038032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 306138032Speter Digital UNIX: Digital UNIX (and possibly others) moves 306238032Speter loader environment variables into the loader memory 306338032Speter area. If one of these environment variables (such as 306438032Speter LD_LIBRARY_PATH) was the last environment variable, 306538032Speter an invalid memory address would be used by the process 306638032Speter title routine causing memory corruption. Problem 306738032Speter noted by Sam Hartman of Mesa Internet Systems. 306838032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 306938032Speter chownsafe() to always return 0 even if the OS does 307038032Speter not permit file giveaways. Problem noted by 307138032Speter Yasutaka Sumi of The University of Tokyo. 307264562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 307338032Speter Gerald Rinske of Siemens Business Services VAS. 307438032Speter Linux: Pad process title with NULLs. Problem noted by 307538032Speter Jon Lewis of Florida Digital Turnpike. 307638032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 307738032Speter incorrect value for the number of interfaces. 307838032Speter Problem noted by Chris Loelke of JetStream Internet 307938032Speter Services. 308038032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 308138032Speter Rinske of Siemens Business Services VAS. 308238032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 308338032Speter used on a Solaris machine. Problem noted by 308438032Speter Stephen Ma of Jtec Pty Limited. 308538032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 308638032Speter Services VAS. 308738032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 308838032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 308938032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 309038032Speter Ericsson. 309138032Speter 309264562Sgshapiro8.8.7/8.8.7 1997/08/03 309338032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 309438032Speter an exclusive lock already set -- i.e., almost all systems 309538032Speter except 4.4-BSD derived systems), the initial attempt at 309638032Speter rebuilding aliases file if the database didn't already 309738032Speter exist would fail. Patch from Raymund Will of LST Software 309838032Speter GmbH. 309938032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 310038032Speter Problem noted by Fredrik J�nsson of the Royal Institute 310138032Speter of Technology, Stockholm. 310238032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 310338032Speter some environments could give "multiple definitions" for these 310438032Speter routines during compilation. If using TCP Wrappers, assume 310538032Speter that these routines are included as though they were in the 310638032Speter C library. Patch from Robert La Ferla. 310738032Speter When a NEWDB database map was rebuilt at the same time it was being 310838032Speter used by a queue run, the maps could be left locked for the 310938032Speter duration of the queue run, causing other processes to hang. 311038032Speter Problem noted by Kendall Libby of Shore.NET. 311138032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 311238032Speter mail was passed on without any recipient header. This could 311338032Speter cause problems downstream. Problem noted by Xander Jansen 311438032Speter of SURFnet ExpertiseCentrum. 311538032Speter Give error when GDBM is used with sendmail. GDBM's locking and 311638032Speter linking of the .dir and .pag files interferes with sendmail's 311738032Speter locking and security checks. Problems noted by Fyodor 311838032Speter Yarochkin of the Kyrgyz Republic FreeNet. 311938032Speter Don't fsync qf files if SuperSafe option is not set. 312038032Speter Avoid extra calls to gethostbyname for addresses for which a 312138032Speter gethostbyaddr found no value. Also, ignore any returns 312238032Speter from gethostbyaddr that look like a dotted quad. 312338032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 312438032Speter "may be forged", since at the network level we pretty much 312538032Speter have to assume that the information is good. 312638032Speter In some cases, errors during an SMTP session could leave files 312738032Speter open or locked. 312838032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 312980785Sgshapiro Better handling of non-set-user-id binaries -- avoids certain obnoxious 313038032Speter errors during testing. 313138032Speter Errors in file locking of NEWDB maps had the incorrect file name 313238032Speter printed in the error message. 313338032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 313438032Speter missing parameter were issued, the EHLO behaved like a HELO. 313538032Speter Load limiting never kicked in for incoming SMTP transactions if the 313643730Speter DeliveryMode=background and any recipient was an alias or 313738032Speter had a .forward file. From Nik Conwell of Boston University. 313838032Speter On some non-Posix systems, the decision of whether chown(2) permits 313938032Speter file giveaway was undefined. From Tetsu Ushijima of the 314038032Speter Tokyo Institute of Technology. 314138032Speter Fix race condition that could cause the body of a message to be 314238032Speter lost (so only the header was delivered). This only occurs 314338032Speter on systems that do not use flock(2), and only when a queue 314438032Speter runner runs during a critical section in another message 314538032Speter delivery. Based on a patch from Steve Schweinhart of 314638032Speter Results Computing. 314738032Speter If a qf file was found in a mail queue directory that had a problem 314838032Speter (wrong ownership, bad format, etc.) and the file name was 314938032Speter exactly MAXQFNAME bytes long, then instead of being tried 315038032Speter once, it would be tried on every queue run. Problem noted 315138032Speter by Bryan Costales of Mercury Mail. 315238032Speter If the system supports an st_gen field in the status structure, 315338032Speter include it when reporting that a file has changed after open. 315438032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 315538032Speter This out to be checked as well as reported, since it is 315638032Speter theoretically possible for an attacker to remove a file after 315738032Speter it is opened and replace it with another file that has the 315838032Speter same i-number, but some filesystems (notably AFS) return 315938032Speter garbage in this field, and hence always look like the file 316038032Speter has changed. As a practical matter this is not a security 316138032Speter problem, since the files can be neither hard nor soft links, 316238032Speter and on no filesystem (that I am aware of) is it possible to 316338032Speter have two files on the same filesystem with the same i-number 316438032Speter simultaneously. 316538032Speter Delete the root Makefile from the distribution -- it is only for 316638032Speter use internally, and does not work at customer sites. 316738032Speter Fix botch that caused the second MAIL FROM: command in a single 316838032Speter transaction to clear the entire transaction. Problem 316938032Speter noted by John Kennedy of Cal State University, Chico. 317038032Speter Work properly on machines that have _PATH_VARTMP defined without 317138032Speter a trailing slash. (And a pox on vendors that decide to 317238032Speter ignore the established conventions!) Problem noted by 317338032Speter Gregory Neil Shapiro of WPI. 317438032Speter Internal changes to make it easier to add another protocol family 317538032Speter (intended for IPv6). Patches are from John Kennedy of 317638032Speter CSU Chico. 317738032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 317838032Speter an extra space at the beginning of some lines. Problem 317938032Speter noted by Charles Karney of Princeton University; fix based 318038032Speter on a patch from Christophe Wolfhugel. 318138032Speter Portability: 318238032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 318338032Speter with the _Sendmail_ book, 2nd edition. Note that 318438032Speter the book is actually wrong: _PATH_SENDMAILCF should 318538032Speter be used instead. 318638032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 318738032Speter of Argonne National Laboratory. 318838032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 318938032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 319038032Speter SunOS: Include <memory.h> to fix warning from util.c. From 319138032Speter James Aldridge of EUnet Ltd. 319238032Speter Solaris: Change STDIR (location of status file) to /etc/mail 319338032Speter in Makefiles. 319438032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 319538032Speter Makefiles. Use NEWDB on Linux instead. 319638032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 319738032Speter exists but behaves differently than other OSes. 319838032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 319938032Speter around the problem. Problem noted by Tom Moore of 320038032Speter NCR Corp. 320138032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 320238032Speter noted by Tom Smith of Digital Equipment Corp. 320338032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 320438032Speter noted by Tom Good of the Community Access Information 320538032Speter Resource Network 320638032Speter SCO 4.2: compile problems caused by a change in the type of 320738032Speter the "length" parameters passed to accept, getpeername, 320838032Speter getsockname, and getsockopt. Adds new compile flags 320938032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.

This makes it possible to create a root 325438032Speter owned file in an arbitrary directory by inserting the symlink 325538032Speter into a writable directory after the initial lstat(2) check 325638032Speter determined that the file did not exist. The only verified 325738032Speter example of a system having these odd semantics for O_EXCL 325838032Speter and symbolic links was HP-UX prior to version 9.07. Most 325938032Speter systems do not have the problem, since a exclusive create 326038032Speter of a file disallows symbolic links. Systems that have been 326138032Speter verified to NOT have the problem include AIX 3.x, *BSD, 326238032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 326338032Speter and Ultrix. This is a potential exposure on systems that 326438032Speter have this bug and which do not have a MAILER-DAEMON alias 326538032Speter pointing at a legitimate account, since this will cause old 326638032Speter mail to be dropped in /var/tmp/dead.letter. 326738032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 326838032Speter if maps or alias files are in world writable directories. 326938032Speter If your system has alias maps in writable directories, it 327038032Speter is potentially possible for an attacker to replace the .db 327138032Speter (or .dir and .pag) files by symbolic links pointing at 327238032Speter another database; this can be used either to expose 327338032Speter information (e.g., by pointing an alias file at /etc/spwd.db 327438032Speter and probing for accounts), or as a denial-of-service attack 327538032Speter (by trashing the password database). The fix disallows 327638032Speter symbolic links entirely when rebuilding alias files or on 327738032Speter maps that are in writable directories, and always warns on 327838032Speter writable directories; 8.9 will probably consider writable 327938032Speter directories to be fatal errors. This does not represent an 328038032Speter exposure on systems that have alias files in unwritable 328138032Speter system directories. 328238032Speter SECURITY: disallow .forward or :include: files that are links (hard 328338032Speter or soft) if the parent directory (or any directory in the 328438032Speter path) is writable by anyone other than the owner. This is 328538032Speter similar to the previous case for user files. This change 328638032Speter should not affect most systems, but is necessary to prevent 328738032Speter an attacker who can write the directory from pointing such 328838032Speter files at other files that are readable only by the owner. 328938032Speter SECURITY: Tighten safechown rules: many systems will say that they 329038032Speter have a safe (restricted to root) chown even on files that 329138032Speter are mounted from another system that allows owners to give 329238032Speter away files. The new rules are very strict, trusting file 329338032Speter ownership only in those few cases where the system has 329438032Speter been verified to be at least as paranoid as necessary. 329538032Speter However, it is possible to relax the rules to partially 329638032Speter trust the ownership if the directory path is not world or 329738032Speter group writable. This might allow someone who has a legitimate 329838032Speter :include: file (referenced directly from /etc/aliases) to 329938032Speter become another non-root user if the :include: file is in a 330038032Speter non-writable directory on an NFS-mounted filesystem where 330138032Speter the local system says that giveaway is denied but it is 330238032Speter actually permitted. I believe this to be a very small set 330338032Speter of cases. If in doubt, do not point :include: aliases at 330438032Speter NFS-mounted filesystems. 330538032Speter SECURITY: When setting a numeric group id using the RunAsUser option 330638032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 330738032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 330838032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 330938032Speter The user id was still set properly. Problem noted by Uli 331038032Speter Pralle of the Technical University of Berlin. 331138032Speter Save the initial gid set for use when checking for if the 331238032Speter PrivacyOptions=restrictmailq option is set. Problem reported 331338032Speter by Wolfgang Ley of DFN-CERT. 331438032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 331538032Speter failure on one message won't affect future messages to the 331638032Speter same host). 331738032Speter IP source route printing had an "off by one" error that would 331838032Speter affect any options that came after the route option. Patch 331938032Speter from Theo de Raadt. 332038032Speter The "Message is too large" error didn't successfully bounce the error 332138032Speter back to the sender. Problem reported by Stephen More of 332238032Speter PSI; patch from Gregory Neil Shapiro of WPI. 332338032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 332438032Speter of 5.1.3); it apparently gets used in multiple ways. 332538032Speter Suggested by John Myers of Portola Communications. 332638032Speter Fix possible extra null byte generated during collection if errors 332738032Speter occur at the beginning of the stream. Patch contributed by 332838032Speter Andrey A. Chernov and Gregory Neil Shapiro. 332938032Speter Code changes to avoid possible reentrant call of malloc/free within 333038032Speter a signal handler. Problem noted by John Beck of Sun 333138032Speter Microsystems. 333238032Speter Move map initialization to be earlier so that check_relay ruleset 333338032Speter will have the latest version of the map data. Problem noted 333438032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 333538032Speter If there are fatal errors during the collection phase (e.g., message 333638032Speter too large) don't send the bogus message. 333738032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 333838032Speter have errors and have owner- aliases. Problem noted by Michael 333938032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 334038032Speter Avoid null pointer dereference on illegal Boundary= parameters in 334138032Speter multipart/mixed Content-Type: header. Problem noted by 334238032Speter Richard Muirden of RMIT University. 334338032Speter Always print error messages during newaliases (-bi) even if the 334438032Speter ErrorMode is not set to "print". Fix from Gregory Neil 334538032Speter Shapiro. 334638032Speter Test mode could core dump if you did a /map lookup in an optional map 334738032Speter that could not be opened. Based on a fix from John Beck of 334838032Speter Sun Microsystems. 334938032Speter If DNS is misconfigured so that the last MX record tried points to 335038032Speter a host that does not have an A record, but other MX records 335138032Speter pointed to something reasonable, don't bounce the message 335238032Speter with a "host unknown" error. Note that this should really 335338032Speter be fixed in the zone file for the domain. Problem noted by 335438032Speter Joe Rhett of Navigist, Inc. 335538032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 335638032Speter the message as having been tried; otherwise the next queue 335738032Speter run will not realize that this is a second attempt and will 335838032Speter retry immediately. Problem noted by Bryan Costales of 335938032Speter Mercury Mail. 336038032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 336138032Speter will be run until the later setting of the clock is reached. 336238032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 336338032Speter Morgan Stanley. 336438032Speter If the load average rises above the cutoff threshold (above which 336538032Speter sendmail will not process the queue at all) during a queue 336638032Speter run, abort the queue run immediately. Problem noted by 336738032Speter Bryan Costales of Mercury Mail. 336838032Speter The variable queue processing algorithm (based on the message size, 336938032Speter number of recipients, message precedence, and job age) was 337038032Speter non-functional -- either the entire queue was processed or 337138032Speter none of the queue was processed. The updated algorithm 337238032Speter does no queue run if a single recipient zero size job will 337338032Speter not be run. 337438032Speter If there is a fatal ("panic") message that will cause sendmail to 337538032Speter die immediately, never hold the error message for future 337638032Speter printing. 337738032Speter Force ErrorMode=print in -bt mode so that all errors are printed 337838032Speter regardless of the setting of the ErrorMode option in the 337938032Speter configuration file. Patch from Gregory Neil Shapiro. 338038032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 338138032Speter routine available in one of the libraries. Use it in conf.h. 338238032Speter The -m (match only) flag now works on host class maps. 338338032Speter If class hash or btree maps are rebuilt, sendmail will now detect 338438032Speter this and reopen the map. Previously, they could give 338538032Speter erroneous results during a single message processing 338638032Speter (but would recover when the next message was received). 338738032Speter Don't delete zero length queue files when doing queue runs until the 338838032Speter files are at least ten minutes old. This avoids a potential 338938032Speter race condition: the creator creates the qf file, getting back 339038032Speter a file descriptor. The queue runner locks it and deletes it 339138032Speter because it is zero length. The creator then writes the 339238032Speter descriptor that is now for a disconnected file, and the 339338032Speter job goes away. Based on a suggestion by Bryan Costales. 339438032Speter When determining the "validated" host name ($_ macro), do a forward 339538032Speter (A) DNS lookup on the result of the PTR lookup and compare 339638032Speter results. If they differ or if the PTR lookup fails, tag the 339738032Speter address as "may be forged". 339838032Speter Log null connections (i.e., hosts that connect but do not do any 339938032Speter substantive activity on the connection before disconnecting; 340038032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 340138032Speter Always permit "writes" to /dev/null regardless of the link count. 340238032Speter This is safe because /dev/null is special cased, and no open 340338032Speter or write is ever actually attempted. Patch from Villy Kruse 340438032Speter of TwinCom. 340538032Speter If a message cannot be sent because of a 552 (exceeded storage 340638032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 340738032Speter was given, don't return the body in the bounce, since there 340838032Speter is a very good chance that the message will double-bounce. 340938032Speter Fix possible line truncation if a quoted-printable had an =00 escape 341038032Speter in the body. Problem noted by Charles Karney of the Princeton 341138032Speter Plasma Physics Laboratory. 341238032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 341338032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 341438032Speter Institute. 341538032Speter The MaxDaemonChildren option wasn't applying to queue runs as 341638032Speter documented. Note that this increases the potential denial 341738032Speter of service problems with this option: an attacker can 341838032Speter connect many times, and thereby lock out queue runs as well 341938032Speter as incoming connections. If you use this option, you should 342038032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 342138032Speter to avoid this attack. Failure to limit noted by Matthew 342238032Speter Dillon of BEST Internet Communications. 342338032Speter Always give a message in newaliases if alias files cannot be 342438032Speter opened instead of failing silently. Suggested by Gregory 342538032Speter Neil Shapiro. This change makes the code match the O'Reilly 342638032Speter book (2nd edition). 342738032Speter Some older versions of the resolver could return with h_errno == -1 342838032Speter if no name server could be reached, causing mail to bounce 342938032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 343038032Speter John Beck of SunSoft. 343138032Speter If a :include: file is owned by a user that does not have an entry 343238032Speter in the passwd file, sendmail could dereference a null pointer. 343338032Speter Problem noted by Satish Mynam of Sun Microsystems. 343438032Speter Take precautions to make sure that the SMTP protocol cannot get out 343538032Speter of sync if (for example) an alias file cannot be opened. 343638032Speter Fix a possible race condition that can cause a SIGALRM to come in 343738032Speter immediately after a SIGHUP, causing the new sendmail to die. 343838032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 343938032Speter from Villy Kruse of TwinCom. 344038032Speter Ignore improperly formatted SMTP reply codes. Previously these were 344138032Speter partially processed, which could cause confusing error 344238032Speter returns. 344338032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 344438032Speter on some architectures. 344538032Speter Portability: 344638032Speter A/UX: from Jim Jagielski of NASA/GSFC. 344738032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 344838032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 344938032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 345038032Speter defined. Problem reported by A Sun of the University 345138032Speter of Washington. 345238032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 345338032Speter the system rather than guessing at compile time. 345438032Speter Patch contributed by John Beck of Sun Microsystems. 345538032Speter Intel Paragon: from Wendy Lin of Purdue University. 345638032Speter GNU Hurd: from Miles Bader of the GNU project. 345738032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 345838032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 345938032Speter Unfortunately releasing them opens a race condition, 346038032Speter but there appears to be no fix for this. Patch from 346138032Speter Gregory Neil Shapiro. 346238032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 346338032Speter Solaris: a bug in strcasecmp caused characters with the 346438032Speter high order bit set to apparently randomly match 346538032Speter letters -- for example, $| (0233) matches "i" and "I". 346638032Speter Problem noted by John Gregson of the University of 346738032Speter Cambridge. 346838032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 346938032Speter Kari Hurtta. 347038032Speter IRIX 6.x: Create Makefiles for systems that claim to be 347138032Speter IRIX64 but are 6.2 or higher (so use the regular 347238032Speter IRIX Makefile). 347338032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 347438032Speter Problem noted by Eric Hagberg of Morgan Stanley. 347538032Speter CONFIG: Some canonification was still done for UUCP-like addresses 347638032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 347738032Speter Brian Candler. 347838032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 347938032Speter local names as local. Problem noted by Jeff Polk of BSDI; 348038032Speter fix provided by Gregory Neil Shapiro. 348138032Speter CONFIG: The "local:user" syntax entries in mailertables and other 348238032Speter "mailer:user" syntax locations returned an incorrect value 348338032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 348438032Speter CONFIG: Retain "+detail" information when forwarding mail to a 348538032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 348638032Speter Guenther of Gustavus Adolphus College. 348738032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 348838032Speter rules are the same as for aliasing. Based on a patch from 348938032Speter Gregory Neil Shapiro. 349038032Speter CONFIG: Break up parsing rules into several pieces; this should 349138032Speter have no functional change in this release, but makes it 349238032Speter possible to have better anti-spam rulesets in the future. 349338032Speter CONFIG: Disallow double dots in host names to avoid having the 349438032Speter HostStatusDirectory store status under the wrong name. 349538032Speter In some cases this can be used as a denial-of-service attack. 349638032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 349738032Speter Gregory Neil Shapiro. 349838032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 349938032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 350038032Speter don't include From_, and convert to 8-bit). Suggestions 350138032Speter from Kimmo Suominen and Roderick Schertler. 350264562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 350338032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 350438032Speter was specified, even when it wasn't. 350538032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 350638032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 350738032Speter "slip in" a symbolic link between the lstat(2) call and the 350838032Speter exclusive open. This is only a problem on System V derived 350938032Speter systems that allow an exclusive create on files that are 351038032Speter symbolic links pointing nowhere. 351138032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 351238032Speter not reset back to root, which on some systems would cause 351338032Speter later mailboxes to fail. Also, any partial message would 351438032Speter not be truncated, which could result in repeated deliveries. 351538032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 351638032Speter developers). 351738032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 351838032Speter change to the sendmail map code was made in 8.8.3. Problem 351938032Speter noted by Gregory Neil Shapiro. 352038032Speter MAKEMAP: Give warnings on file problems such as map files that are 352180785Sgshapiro symbolic links; although makemap is not set-user-id root, it is 352238032Speter often run as root and hence has the potential for the same 352338032Speter sorts of problems as alias rebuilds. 352438032Speter MAKEMAP: Change compilation so that it will link properly on 352538032Speter NEXTSTEP. 352638032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 352738032Speter Accept an optional list of arguments following the server 352838032Speter name for the ETRN arguments to use (instead of $=w).

This 353238032Speter Perl script converts GECOS information in the /etc/passwd 353338032Speter file into aliases, allowing for faster access to full name 353438032Speter lookups; it is also clever about adding aliases (to root) 353538032Speter for system accounts. 353638032Speter NEW FILES: 353738032Speter src/safefile.c 353838032Speter cf/ostype/gnuhurd.m4 353938032Speter cf/ostype/irix6.m4 354038032Speter contrib/passwd-to-alias.pl 354138032Speter src/Makefiles/Makefile.IRIX64.6.1 354238032Speter src/Makefiles/Makefile.IRIX64.6.x 354338032Speter RENAMED FILES: 354438032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 354538032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 354638032Speter 354764562Sgshapiro8.8.5/8.8.5 1997/01/21 354838032Speter SECURITY: Clear out group list during startup. Without this, sendmail 354938032Speter will continue to run with the group permissions of the caller, 355038032Speter even if RunAsUser is specified. 355138032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 355238032Speter to any known attack, but it's best to be conservative. 355338032Speter Suggested by Peter Wemm of DIALix. 355438032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 355538032Speter security implications. Patch from Alex Garthwaite of the 355638032Speter University of Pennsylvania. 355738032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 355838032Speter would truncate the address after "Full". Although the -f 355938032Speter syntax is incorrect (since it is in the envelope, it 356038032Speter shouldn't have comments and full names), the failure mode 356138032Speter was unnecessarily awful. 356238032Speter Fix a possible null pointer dereference when converting 8-bit data 356338032Speter to a 7-bit format. Problem noted by Jim Hutchins of 356438032Speter Sandia National Labs and David James of British Telecom. 356538032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 356638032Speter runs. Although this really shouldn't be used (F=9 is for 356738032Speter final delivery only, and using it on an SMTP mailer makes 356838032Speter it possible for a message to be converted from 8->7->8->7 356938032Speter bits several times), it shouldn't have failed with a syserr. 357038032Speter Problem noted by Eric Hagberg of Morgan Stanley. 357138032Speter _Really_ fix the multiple :maildrop code in the user database 357238032Speter module. Patch from Roy Mongiovi of Georgia Tech. 357338032Speter Let F lines in the configuration file actually read root-only 357438032Speter files if the configuration file is safe. Based on a 357538032Speter patch from Keith Reynolds of SCO. 357638032Speter ETRN followed by QUIT would hold the connection open until the queue 357738032Speter run completed. Problem noted by Truck Lewis of TDK 357838032Speter Semiconductor Corp. 357938032Speter It turns out that despite the documentation, the TCP wrappers library 358038032Speter does _not_ log rejected connections. Do the logging ourselves. 358138032Speter Problem noted by Fletcher Mattox of the University of Texas 358238032Speter at Austin. 358338032Speter If sendmail finds a qf file in its queue directory that is an unknown 358438032Speter version (e.g., when backing out to an old version), the 358538032Speter error is reported on every queue run. Change it to only 358638032Speter give the error once (and rename the qf => Qf). Patch from 358738032Speter William A. Gianopoulos of Raytheon Company. 358838032Speter Start a new session when doing background delivery; currently it 358938032Speter ignored signals but didn't start a new signal, that caused 359038032Speter some problems if a background process tried to send mail 359138032Speter under certain circumstances. Problem noted by Eric Hagberg 359238032Speter of Morgan Stanley; fix from Kari Hurtta. 359338032Speter Simplify test for skipping a queue run to just check if the current 359438032Speter load average is >= the queueing load average. Previously 359538032Speter the check factored in some other parameters that caused it 359638032Speter to essentially never skip the queue run. Patch from Bryan 359738032Speter Costales. 359838032Speter If the SMTP server is running in "nullserver" mode (that is, it is 359938032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 360038032Speter (25) commands; this helps prevent a bad guy from putting 360138032Speter you into a tight loop as a denial-of-service attack. Based 360238032Speter on an e-mail conversation with Brad Knowles of AOL. 360338032Speter Slow down when too many "light weight" commands have been issued; 360438032Speter this helps prevent a class of denial-of-service attacks. 360538032Speter The current values and defaults are: 360638032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 360738032Speter MAXHELOCOMMANDS 3 HELO, EHLO 360838032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 360938032Speter MAXETRNCOMMANDS 8 ETRN 361038032Speter These will probably be configurable in a future release. 361138032Speter On systems that have uid_t typedefed to be an unsigned short, programs 361238032Speter that had the F=S flag and no U= equate would be invoked with 361338032Speter the real uid set to 65535 rather than being left unchanged. 361438032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 361538032Speter by Steve Hubert of the University of Washington, Seattle. 361638032Speter Mail that was Quoted-Printable encoded and had a soft line break on 361738032Speter the last line (i.e., an incomplete continuation) had the last 361838032Speter line dropped. Since this appears to be illegal it isn't 361938032Speter clear what to do with it, but flushing the last line seems 362038032Speter to be a better "fail soft" approach. Based on a patch from 362138032Speter Eric Hagberg. 362238032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 362338032Speter bogus HELO command still causes the "Polite people say HELO 362438032Speter first" error message. Problem pointed out by Chris Thomas 362538032Speter of UCLA; patch from John Beck of SunSoft. 362638032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 362771345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 362871345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 362971345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 363038032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 363138032Speter in a DATA transaction to be sticky; these can occur because 363238032Speter a message is too large, and smaller messages should still go 363338032Speter through. Problem noted by Matt Dillon of Best Internet 363438032Speter Communications. 363538032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 363638032Speter had been successfully delivered to the envelope sender. 363738032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 363838032Speter Gregory Neil Shapiro of WPI. 363938032Speter Give better diagnostics on long alias lines. Based on code contributed 364038032Speter by Patrick Gosling of the University of Cambridge. 364138032Speter Increase the number of virtual interfaces that will be probed for 364238032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 364338032Speter PORTABILITY: 364438032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 364538032Speter Toshiaki Nomura of Fujitsu Limited. 364638032Speter SunOS with LDAP support: compile problems with struct timeval. 364738032Speter Patch from Nick Cuccia of TCSI Corporation. 364838032Speter SCO: from Keith Reynolds of SCO. 364938032Speter Solaris: kstat load average computation wasn't being used. 365038032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 365138032Speter (Moscow). 365238032Speter OpenBSD: from Jason Downs of teeny.org. 365338032Speter Altos System V: from Tim Rice. 365438032Speter Solaris 2.5: from Alan Perry of SunSoft. 365538032Speter Solaris 2.6: from John Beck of SunSoft. 365638032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 365738032Speter of Pratt & Whitney <miorelli@pweh.com>. 365838032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 365938032Speter _just_right_ yet. Tweak it again. I'll omit the names 366038032Speter of the "contributors" (quantity two) in this one case. 366138032Speter As of now, NO MORE DISCUSSION about the syntax of the 366238032Speter Received: line. 366338032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 366438032Speter it never inserts that class into the output file. Fix it 366538032Speter so it will honor EXPOSED_USER but will _not_ include root 366638032Speter automatically in this class. Problem noted by Ronan KERYELL 366738032Speter of Centre de Recherche en Informatique de l'�cole Nationale 366838032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 366938032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 367038032Speter such as LUSER_RELAY. This change permits the following 367138032Speter syntaxes: ``local:'' will send to the same user on the 367238032Speter local machine (e.g., in a mailertable entry for "host", 367338032Speter ``local:'' will cause an address addressed to user@host to 367438032Speter go to user on the local machone). ``local:user'' will send 367538032Speter to the named user on the local machine. ``local:user@host'' 367638032Speter is equivalent to ``local:user'' (the host is ignored). In 367738032Speter all cases, the original user@host is passed in $@ (i.e., the 367838032Speter detail information). Inspired by a report from Michael Fuhr. 367938032Speter CONFIG: Strip quotes from the first word of an "error:" host 368038032Speter indication. This lets you set (for example) the LUSER_RELAY 368138032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 368238032Speter of the \" so that the resulting string is properly quoted. 368338032Speter Problem noted by Gregory Neil Shapiro of WPI. 368438032Speter OP.ME: documentation was inconsistent about whether sendmail did a 368538032Speter NOOP or a RSET to probe the connection (it does a RSET). 368638032Speter Inconsistency noted by Deeran Peethamparam. 368738032Speter OP.ME: insert additional blank pages so it will print properly on 368838032Speter a duplex printer. From Matthew Black of Cal State University, 368938032Speter Long Beach. 369038032Speter 369164562Sgshapiro8.8.4/8.8.4 1996/12/02 369238032Speter SECURITY: under some circumstances, an attacker could get additional 369338032Speter permissions by hard linking to files that were group 369438032Speter writable by the attacker. The solution is to disallow any 369538032Speter files that have hard links -- this will affect .forward, 369638032Speter :include:, and output files. Problem noted by Terry 369738032Speter Kyriacopoulos of Interlog Internet Services. As a 369838032Speter workaround, set UnsafeGroupWrites -- always a good idea. 369938032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 370038032Speter is, it is possible to do a denial-of-service attack on 370138032Speter MX hosts that rely on the use of the null MX list. There 370238032Speter is no danger if you have this option turned off (the default). 370338032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 370438032Speter unsafe. I know of no specific attack against this, although 370538032Speter a denial-of-service attack is probably possible, but in theory 370638032Speter you should not be able to safely tweak anything that affects 370738032Speter the permissions that are used when mail is delivered. 370838032Speter Purgestat could go into an infinite loop if one of the host status 370938032Speter directories somehow became empty. Problem noted by Roy 371038032Speter Mongiovi of Georgia Tech. 371138032Speter Processes got "lost" when counting children due to a race condition. 371238032Speter This caused "proc_list_probe: lost pid" messages to be logged. 371338032Speter Problem noted by several people. 371438032Speter On systems with System V SIGCLD child signal semantics (notably AIX 371538032Speter and HP-UX), mail transactions would print the message "451 371638032Speter SMTP-MAIL: lost child: No child processes". Problem noted 371738032Speter by several people. 371838032Speter Miscellaneous compiler warnings on picky compilers (or when setting 371938032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 372038032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 372138032Speter not be persistent between runs, since they are based on the 372238032Speter message rather than the host. Problem noted by Matt Dillon 372338032Speter of Best Internet Communications. 372438032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 372538032Speter of NCR (a.k.a., AT&T Global Information Solutions). 372638032Speter Avoid the possibility of having a child daemon run to completion 372738032Speter (including closing the SMTP socket) before the parent has 372838032Speter had a chance to close the socket; this can cause the parent 372938032Speter to hang for a long time waiting for the socket to drain. 373038032Speter Patch from Don Lewis of TDK Semiconductor. 373138032Speter If the fork() failed in a queue run, the queue runners would not be 373238032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 373338032Speter Some error conditions in ETRN could cause output without an SMTP 373438032Speter status code. Problem noted by Don Lewis. 373538032Speter Multiple :maildrop addresses in the user database didn't work properly. 373638032Speter Patch from Roy Mongiovi of Georgia Tech. 373738032Speter Add ".db" automatically onto any user database spec that does not 373838032Speter already have it; this is for consistency with makemap, the 373938032Speter K line, and the documentation. Inconsistency pointed out 374038032Speter by Roy Mongiovi. 374138032Speter Allow sendmail to be properly called in nohup mode. Patch from 374238032Speter Kyle Jones of UUNET. 374338032Speter Change ETRN to ignore but still update host status files; previously 374438032Speter it would ignore them and not save the updated status, which 374538032Speter caused stale information to be maintained. Based on a patch 374638032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 374738032Speter ETRN ignore the MinQueueAge option. 374838032Speter Patch long term host status to recover more gracefully from an empty 374938032Speter host status file condition. Patch from NAKAMURA Motonori 375038032Speter of Kyoto University. 375138032Speter Several patches to signal handling code to fix potential race 375238032Speter conditions from Don Lewis. 375338032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 375438032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 375538032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 375638032Speter compile flag; use NETINET instead. Solution based on a 375738032Speter patch from Bryan Costales. 375838032Speter PORTABILITY FIXES: 375938032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 376038032Speter /etc/security/passwd file when called as root. This 376138032Speter is very slow on some systems. To speed it up, use the 376238032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 376338032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 376438032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 376538032Speter Glicker of Burrelle's Information Service. 376638032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 376738032Speter from Makoto MATSUSHITA of Osaka University. 376838032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 376938032Speter Leeds University and SASABE Tetsuro of the University 377038032Speter of Tokyo. 377138032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 377238032Speter Services, Inc. 377338032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 377438032Speter I believe this to have only been a problem if you 377538032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 377638032Speter to stick with /etc/sendmail.cf as your One True Path. 377738032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 377838032Speter Martin Laubach of the Technischen Universit�t Wien. 377938032Speter CONFIG: change default Received: line to be multiple lines rather 378038032Speter than one long one. By popular demand. 378138032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 378238032Speter from Jerome Berkman of U.C. Berkeley. 378338032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 378438032Speter to take a very long time. Problem noted by Yoshiro YONEYA 378538032Speter of NTT Software Corporation. 378638032Speter CONTRIB: add etrn.pl, contributed by John Beck. 378738032Speter NEW FILES: 378838032Speter contrib/etrn.pl 378938032Speter 379064562Sgshapiro8.8.3/8.8.3 1996/11/17 379138032Speter SECURITY: it was possible to get a root shell by lying to sendmail 379238032Speter about argv[0] and then sending it a signal. Problem noted 379338032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 379438032Speter best-of-security list. 379538032Speter Log sendmail binary version number in "Warning: .cf version level 379638032Speter (%d) exceeds program functionality (%d) message" -- this 379738032Speter should make it clearer to people that they are running 379838032Speter the wrong binary. 379938032Speter Fix a problem that occurs when you open an SMTP connection and then 380038032Speter do one or more ETRN commands followed by a MAIL command; at 380138032Speter the end of the DATA phase sendmail would incorrectly report 380238032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 380338032Speter noted by Eric Bishop of Virginia Tech. 380438032Speter When doing text-based host canonification (typically /etc/hosts 380538032Speter lookup), a null host name would match any /etc/hosts entry 380638032Speter with space at the end of the line. Problem noted by Steve 380738032Speter Hubert of the University of Washington, Seattle. 380838032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 380938032Speter Problem reported by Tom Smith of Digital Equipment Corp. 381038032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 381138032Speter size PACKETSZ (512) is not sufficient for some nameserver 381238032Speter answers containing very many resource records. The resolver 381338032Speter may also switch to TCP and retry if it detects UDP packet 381438032Speter overflow. Also, allow for the fact that the resolver 381538032Speter routines res_query and res_search return the size of the 381638032Speter *un*truncated answer in case the supplied answer buffer it 381738032Speter not big enough to accommodate the entire answer. Patch from 381838032Speter Eric Wassenaar. 381938032Speter Improvements to MaxDaemonChildren code. If you think you have too 382038032Speter many children, probe the ones you have to verify that they 382138032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 382238032Speter Also, do this probe before growing the vector of children 382338032Speter pids; this previously caused the vector to grow indefinitely 382438032Speter due to a race condition. Problem reported by Kyle Jones of 382538032Speter UUNET. 382638032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 382738032Speter O_EXLOCK to zero; this fools the map compilation code into 382838032Speter thinking that it can avoid race conditions by locking on open. 382938032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 383038032Speter Leif Erlingsson of Data Lege. 383138032Speter Always call res_init() on startup (if compiled in, of course) to 383238032Speter allow the sendmail.cf file to tweak resolver flags; without 383338032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 383438032Speter Andrew Sun of Merrill Lynch. 383538032Speter Improvements to host status printing code. Suggested by Steve Hubert 383638032Speter of the University of Washington, Seattle. 383738032Speter Change MinQueueAge option processing to do the check for the job age 383838032Speter when reading the queue file, rather than at the end; this 383938032Speter avoids parsing the addresses, which can do DNS lookups. 384038032Speter Problem noted by John Beck of InReference, Inc. 384138032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 384238032Speter properly escaped. Problem noted by Peter Nilsson of the 384338032Speter University of Linkoping. 384438032Speter In some cases, sendmail would retain root permissions during queue 384538032Speter runs even if RunAsUser was set. Problem noted by Mark 384638032Speter Thomas of Mark G. Thomas Consulting. 384738032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 384838032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 384938032Speter the envelope, and the receiving SMTP server speaks DSN, then 385038032Speter the DSN would be both generated locally and propagated to the 385138032Speter other end. 385238032Speter The U= mailer field didn't correctly extract the group id if the 385338032Speter user id was numeric. Problem noted by Kenneth Herron of 385438032Speter MCI Telecommunications Communications. 385538032Speter If a message exceeded the fixed maximum size on input, the body of 385638032Speter the message was included in the bounce. Note that this did 385738032Speter not occur if it exceeded the maximum _output_ size. Problem 385838032Speter reported by Kyle Jones of UUNET. 385938032Speter PORTABILITY FIXES: 386038032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 386138032Speter AIX4 defines to use seteuid(2) instead, which 386238032Speter works on 4.1 as well as 4.2. Problem noted by 386338032Speter H�kan Lindholm of interAF, Sweden. 386438032Speter AIX4: use tzname[] vector to determine time zone name. 386538032Speter Patch from NAKAMURA Motonori of Kyoto University. 386638032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 386738032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 386838032Speter Solaris: kstat(3k) support for retrieving the load average. 386938032Speter This adds the LA_KSTAT definition for LA_TYPE. 387038032Speter The outline of the implementation was contributed 387138032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 387238032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 387338032Speter declaration of struct rusage at the top of conf.h; 387438032Speter change it to only be included if you are using gcc, 387538032Speter which is apparently the only compiler that requires 387638032Speter it in the first place. Problem noted by Jeff 387738032Speter Earickson of Colby College. 387838032Speter IRIX: don't default to using gcc. IRIX is a civilized 387938032Speter operating system that comes with a decent compiler 388038032Speter by default. Problem noted by Barry Bouwsma and 388138032Speter Kari Hurtta. 388238032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 388338032Speter consistency with other local mailers. Inconsistency 388438032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 388538032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 388638032Speter overhead) as part of the bestmx_is_local feature, the 388738032Speter domain part was dropped from the name. Patch from Steve 388838032Speter Hubert of the University of Washington, Seattle. 388938032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 389038032Speter end up being translated to the null host name, which would 389138032Speter return any entry in /etc/hosts that had a space at the end 389238032Speter of the line. Problem noted by Steve Hubert of the 389338032Speter University of Washington, Seattle. 389438032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 389538032Speter Polytechnic Institute. 389638032Speter MAKEMAP: tweak hash and btree parameters for better performance. 389738032Speter Patch from Matt Dillon of Best Internet Communications. 389838032Speter NEW FILES: 389938032Speter src/Makefiles/Makefile.Linux.ppc 390038032Speter cf/ostype/aix4.m4 390138032Speter cf/ostype/mklinux.m4 390238032Speter 390364562Sgshapiro8.8.2/8.8.2 1996/10/18 390438032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 390538032Speter changed the code but didn't fix the problem. 390638032Speter PORTABILITY FIXES: 390738032Speter Solaris: Don't use the system getusershell(3); it can 390838032Speter apparently corrupt the heap in some circumstances. 390938032Speter Problem found by Ken Pizzini of Spry, Inc. 391038032Speter OP.ME: document several mailer flags that were accidentally omitted 391138032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 391238032Speter CONFIG: no changes. 391338032Speter 391464562Sgshapiro8.8.1/8.8.1 1996/10/17 391538032Speter SECURITY: unset all environment variables that the resolver will 391638032Speter examine during queue runs and daemon mode. Problem noted 391738032Speter by Dan Bernstein of the University of Illinois at Chicago. 391838032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 391938032Speter message could overflow a buffer if it was converted back 392038032Speter to 8 bits. This caused core dumps and has the potential 392138032Speter for a remote attack. Problem first noted by Gregory Shapiro 392238032Speter of WPI. 392338032Speter Avoid duplicate deliveries of error messages on systems that don't 392438032Speter have flock(2) support. Patch from Motonori Nakamura of 392538032Speter Kyoto University. 392638032Speter Ignore null FallBackMX (V) options. If this option is null (as 392738032Speter opposed to undefined) it can cause "null signature" syserrs 392838032Speter on illegal host names. 392938032Speter If a Base64 encoded text/plain message has no trailing newline in 393038032Speter the encoded text, conversion back to 8 bits will drop the 393138032Speter final line. Problem noted by Pierre David. 393238032Speter If running with a RunAsUser, sendmail would give bogus "cannot 393338032Speter setuid" (or seteuid, or setreuid) messages on some systems. 393438032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 393538032Speter Always print error messages in -bv mode -- previously, -bv would 393638032Speter be absolutely silent on errors if the error mode was sent 393738032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 393838032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 393938032Speter term host status. This is necessary because it is common 394038032Speter to do this when you know a host has just come back up. 394138032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 394238032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 394338032Speter University of Leicester. 394438032Speter If a service (such as NIS) is specified as the last entry in the 394538032Speter service switch, but that service is not compiled in, sendmail 394638032Speter would return a temporary failure when an entry was not found 394738032Speter in the map. This caused the message to be queued instead of 394838032Speter bouncing immediately. Problem noted by Harry Edmon of the 394938032Speter University of Washington. 395038032Speter PORTABILITY FIXES: 395138032Speter Solaris 2.3 had compilation problems in conf.c. Several 395238032Speter people pointed this out. 395338032Speter NetBSD from Charles Hannum of MIT. 395438032Speter AIX4 improvements based on info from Steve Bauer of South 395538032Speter Dakota School of Mines & Technology. 395638032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 395738032Speter Patch from Gil Kloepfer Jr. 395838032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 395938032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 396038032Speter were also in $=w. Problem noted by Zoltan Basti of 396138032Speter Softec. 396238032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 396338032Speter on a patch from Eric Hagberg of Morgan Stanley. 396438032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 396538032Speter of Stanford via Robert La Ferla. 396638032Speter 396764562Sgshapiro8.8.0/8.8.0 1996/09/26 396838032Speter Under some circumstances, Bcc: headers would not be properly 396938032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 397038032Speter Log a warning if the sendmail daemon is invoked without a full 397138032Speter pathname, which prevents "kill -1" from working. I was 397238032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 397338032Speter Fix small buffer overflow. Since the data in this buffer was not 397438032Speter read externally, there was no security problem (and in fact 397538032Speter probably wouldn't really overflow on most compilers). Pointed 397638032Speter out by KIZU takashi of Osaka University. 397738032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 397838032Speter if a FallbackMXHost was specified in the configuration file 397938032Speter -- all mail would be sent to the fallback even if the original 398038032Speter host was accessible. Pointed out by Munenari Hirayama of 398138032Speter NSC (Japan). 398238032Speter A message that didn't terminate with a newline would (sometimes) not 398338032Speter have the trailing "." added properly in the SMTP dialogue, 398438032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 398538032Speter The DaemonPortOptions suboption to bind to a particular address was 398638032Speter incorrect and nonfunctional due to a misunderstanding of the 398738032Speter semantics of binding on a passive socket. Patch from 398838032Speter NIIBE Yutaka of Mitsubishi Research Institute. 398938032Speter Increase the number of MX hosts for a single name to 100 to better 399038032Speter handle the truly huge service providers such as AOL, which 399138032Speter has 13 at the moment (and climbing). In order to avoid 399238032Speter trashing memory, the buffer for all names has only been 399338032Speter slightly increased in size, to 12.8K from 10.2K -- this means 399438032Speter that if a single name had 100 MX records, the average size 399538032Speter of those records could not exceed 128 bytes. Requested by 399638032Speter Brad Knowles of America On Line. 399738032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 399838032Speter Urged by Dan Bernstein of U.C. Berkeley. 399938032Speter Print q_statdate and q_specificity in address structure debugging 400038032Speter printout. 400138032Speter Expand MCI structure flag bits for debugging output. 400238032Speter Support IPv6-style domain literals, which can have colons between 400338032Speter square braces. 400438032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 400538032Speter this is an attempt to track down a bug that one person seems 400638032Speter to be having (it may be a Solaris bug!). 400738032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 400838032Speter this caused the NOTIFY info to sometimes be lost. Problem 400938032Speter pointed out by Claus Assmann of the 401038032Speter Christian-Albrechts-University of Kiel. 401138032Speter The statistics gathered in the sendmail.st file were too high; in 401238032Speter some cases failures (e.g., user unknown or temporary failure) 401338032Speter would count as a delivery as far as the statistics were 401438032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 401538032Speter Systems that don't have flock() would not send split envelopes in 401638032Speter the initial run. Problem pointed out by Leonard Zubkoff of 401738032Speter Dandelion Digital. 401838032Speter Move buffer overflow checking -- these primarily involve distrusting 401938032Speter results that may come from NIS and DNS. 402038032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 402138032Speter include <paths.h> and hence had the wrong pathnames for a few 402238032Speter things like /var/tmp. Reported by Matthew Green. 402338032Speter Conditions were reversed for the Priority: header, resulting in all 402438032Speter values being interpreted as non-urgent except for non-urgent, 402538032Speter which was interpreted as normal. Patch from Bryan Costales. 402638032Speter The -o (optional) flag was being ignored on hash and btree maps 402738032Speter since 8.7.2. Fix from Bryan Costales. 402838032Speter Content-Types listed in class "q" will always be encoded as 402938032Speter Quoted-Printable (or more accurately, will never be encoded 403038032Speter as base64). The class can have primary types (e.g., "text") 403138032Speter or full types (e.g., "text/plain"). Based on a suggestion by 403238032Speter Marius Olafsson of the University of Iceland. 403338032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 403438032Speter dialogue) so it can be passed to programs in mailers. 403538032Speter Define ${bodytype} to be the body type (from the -B flag or the 403638032Speter BODY= ESMTP parameter) so it can be passed to programs in 403738032Speter mailers. 403838032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 403938032Speter flag is set in the mailer descriptor. Suggested by John 404038032Speter Myers of CMU. 404138032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 404238032Speter The command takes a host name; data for that host is 404338032Speter immediately (and asynchronously) flushed. Because this shares 404438032Speter the -qR implementation, other hosts may be attempted, but 404538032Speter there should be no security implications. Implementation 404638032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 404738032Speter Add three new command line flags to pass in DSN parameters: -V envid 404838032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 404938032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 405038032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 405138032Speter that the -N flag applies to all recipients; there is no way 405238032Speter to specify per-address notifications on the command line, 405338032Speter nor is there an equivalent for the ORCPT= per-address 405438032Speter parameter. 405538032Speter Restore LogLevel option to be safe (it can only be increased); 405638032Speter apparently I went into paranoid mode between 8.6 and 8.7 405738032Speter and made it unsafe. Pointed out by Dabe Murphy of the 405838032Speter University of Maryland. 405938032Speter New logging on log level 15: all SMTP traffic. Patches from 406038032Speter Andrew Gross of San Diego Supercomputer Center. 406138032Speter NetInfo property value searching code wasn't stopping when it found 406238032Speter a match. This was causing the wrong values to be found (and 406338032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 406438032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 406538032Speter out by Bill Wisner of Electronics for Imaging that you can't 406638032Speter use the bracket address form for the MAIL_HUB macro, since 406738032Speter that causes the brackets to remain in the envelope recipient 406838032Speter address used for delivery. The simple fix (stripping off the 406938032Speter brackets in the config file) breaks the use of IP literal 407038032Speter addresses. This flag will solve that problem. 407138032Speter Add MustQuoteChars option. This is a list of characters that must 407238032Speter be quoted if they are found in the phrase part of an address 407338032Speter (that is, the full name part). The characters @,;:\()[] are 407438032Speter always in this list and cannot be removed. The default is 407538032Speter this list plus . and ' to match RFC 822. 407638032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 407738032Speter that do not include a host name for back compatibility with 407838032Speter some stupid SMTP clients. Setting this violates RFC 1123 407938032Speter section 5.2.5. 408038032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 408138032Speter rejecting connections if it has more than this many 408238032Speter outstanding children accepting mail. Note that you may 408338032Speter see more processes than this because of outgoing mail; this 408438032Speter is for incoming connections only. 408538032Speter Add ConnectionRateThrottle option. If set to a positive value, the 408638032Speter number of incoming SMTP connections that will be permitted 408738032Speter in a single second is limited to this number. Connections are 408838032Speter not refused during this time, just deferred. The intent is to 408938032Speter flatten out demand so that load average limiting can kick in. 409038032Speter It is less radical than MaxDaemonChildren, which will stop 409138032Speter accepting connections even if all the connections are idle 409238032Speter (e.g., due to connection caching). 409338032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 409438032Speter specifies how long cached information about the state of a 409538032Speter host will be kept before they are considered stale and the 409638032Speter host is retried. If you are using persistent host status 409738032Speter (i.e., the HostStatusDirectory option is set) this will apply 409838032Speter between runs; otherwise, it applies only within a single queue 409938032Speter run and hence is useful only for hosts that have large queues 410038032Speter that take a very long time to run. 410138032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 410238032Speter into being a single line even if they had newlines in them 410338032Speter when read. This is to get around a botch in Lotus Notes. 410438032Speter Text class maps were totally broken -- if you ever retrieved the last 410538032Speter item in a table it would be truncated. Problem noted by 410638032Speter Gregory Neil Shapiro of WPI. 410738032Speter Extend the lines printed by the mailq command (== the -bp flag) when 410838032Speter -v is given to 120 characters; this allows more information 410938032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 411038032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 411138032Speter this was treated as end-of-input. Problem noted by Bryan 411238032Speter Costales. 411338032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 411438032Speter to the queue file. Fix from John Hughes of Atlantic 411538032Speter Technologies, Inc. 411638032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 411738032Speter if this happens in a queue run it can cause nasty delays. 411838032Speter Problem noted by Mark Horton of AT&T. 411938032Speter If userdb entries pointed to userdb entries, and there were multiple 412038032Speter values for a given key, the database cursor would get 412138032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 412238032Speter of Georgia Tech. Fixed by reading all the values and creating 412338032Speter a comma-separated list; thus, the -v output will be somewhat 412438032Speter different for this case. 412538032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 412638032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 412738032Speter of Stanford University. 412838032Speter When envelopes were split due to aliases with owner- aliases, and 412938032Speter there was some error on one of the lists, more than one of 413038032Speter the owners would get the message. Problem pointed out by 413138032Speter Roy Mongiovi of Georgia Tech. 413238032Speter Detect excessive recursion in macro expansions, e.g., $X defined 413338032Speter in terms of $Y which is defined in terms of $X. Problem 413438032Speter noted by Bryan Costales; patch from Eric Wassenaar. 413538032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 413638032Speter some cases get trashed causing bogus From_ lines. Fix from 413738032Speter Kyle Jones of UUNET. 413838032Speter When doing load average initialization, if the nlist call for avenrun 413938032Speter failed, the second and subsequent lookups wouldn't notice 414038032Speter that fact causing bogus load averages to be returned. Noted 414138032Speter by Casper Dik of Sun Holland. 414238032Speter Fix problem with incompatibility with some versions of inet_aton that 414338032Speter have changed the return value to unsigned, so a check for an 414438032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 414538032Speter This could cause mail to addresses such as [foo.com] to bounce 414638032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 414738032Speter Pasteur Institute. 414838032Speter DSNs were inconsistent if a failure occurred during the DATA phase 414938032Speter rather than the RCPT phase: the Action: would be correct, but 415038032Speter the detailed status information would be wrong. Problem noted 415138032Speter by Bob Snyder of General Electric Company. 415238032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 415338032Speter that this is the initial MUA->MTA submission. The flag current 415438032Speter does nothing, but in future releases (when MUAs start using 415538032Speter these flags) it will probably turn on things like DNS 415638032Speter canonification. 415738032Speter Default end-of-line string (E= specification on mailer [M] lines) 415838032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 415938032Speter mailers. 416038032Speter Change the internal definition for the *file* and *include* mailers 416138032Speter to have $u in the argument vectors so that they aren't 416238032Speter misinterpreted as SMTP mailers and thus use \r\n line 416338032Speter termination. This will affect anyone who has redefined 416438032Speter either of these in their configuration file. 416538032Speter Don't assume that IDENT servers close the connection after a query; 416638032Speter responses can be newline terminated. From Terry Kennedy of 416738032Speter St. Peter's College. 416838032Speter Avoid core dumps on erroneous configuration files that have 416938032Speter $#mailer with nothing following. From Bryan Costales. 417038032Speter Avoid null pointer dereference with high debug values in unlockqueue. 417138032Speter Fix from Randy Martin of Clemson University. 417238032Speter Fix possible buffer overrun when expanding very large macros. Fix 417338032Speter from Kyle Jones of UUNET. 417438032Speter After 25 EXPN or VRFY commands, start pausing for a second before 417538032Speter processing each one. This avoids a certain form of denial 417638032Speter of service attack. Potential attack pointed out by Bryan 417738032Speter Costales. 417838032Speter Allow new named (not numbered!) config file rules to do validity 417938032Speter checking on SMTP arguments: check_mail for MAIL commands and 418038032Speter check_rcpt for RCPT commands. These rulesets can do anything 418138032Speter they want; their result is ignored unless they resolve to the 418238032Speter $#error mailer, in which case the indicated message is printed 418338032Speter and the command is rejected. Similarly, the check_compat 418438032Speter ruleset is called before delivery with "from_addr $| to_addr" 418538032Speter (the $| is a meta-symbol used to separate the two addresses); 418638032Speter it can give a "this sender can't send to this recipient" 418738032Speter notification. Note that this patch allows $| to stand alone 418838032Speter in rulesets. 418938032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 419038032Speter that have the name, IP address, and port number (respectively) 419138032Speter of the SMTP client (that is, the entity at the other end of 419238032Speter the connection. These can be used in (e.g.) check_rcpt to 419338032Speter verify that someone isn't trying to relay mail through your 419438032Speter host inappropriately. Be sure to use the deferred evaluation 419538032Speter form, for example $&{client_name}, to avoid having these bound 419638032Speter when sendmail reads the configuration file. 419738032Speter Add new config file rule check_relay to check the incoming connection 419838032Speter information. Like check_compat, it is passed the host name 419938032Speter and host address separated by $| and can reject connections 420038032Speter on that basis. 420138032Speter Allow IDA-style recursive function calls. Code contributed by Mark 420238032Speter Lovell and Paul Vixie. 420338032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 420438032Speter a virtual UUCP address using either a domain address or the $k 420538032Speter macro. Based on code contributed by Mark Lovell and Paul 420638032Speter Vixie. 420738032Speter Add Stanford LDAP map. Requires special libraries that are not 420838032Speter included with sendmail. Contributed by Booker C. Bense 420938032Speter <bbense@networking.stanford.edu>; contact him for support. 421038032Speter See also the src/READ_ME file. 421138032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 421238032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 421338032Speter only for debugging deep bits of code where it is important to 421438032Speter distinguish between the single-character metasymbol $+ and the 421538032Speter two characters $, +. 421638032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 421738032Speter debug_dumpstate. 421838032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 421938032Speter files that are group writable are considered "unsafe" -- that 422038032Speter is, programs and files referenced from such files are not 422138032Speter valid recipients. 422238032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 422338032Speter name that was not in DNS or was a domain-literal. Problem 422438032Speter noted by Tom May. 422538032Speter Change the introduction to error messages to more clearly delineate 422638032Speter permanent from temporary failures; if both existed in a 422738032Speter single message it could be confusing. Suggested by John 422838032Speter Beck of InReference, Inc. 422938032Speter The IngoreDot (i) option didn't work for lines that were terminated 423038032Speter with CRLF. Problem noted by Ted Stockwell of Secure 423138032Speter Computing Corporation. 423238032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 423338032Speter message headers. Problem reported by Matt Dillon of Best 423438032Speter Internet Communications. 423538032Speter Check for bogus characters in the 0200-0237 range; since these are 423638032Speter used internally, very strange errors can occur if those 423738032Speter characters appear in headers. Problem noted by Anders Gertz 423838032Speter of Lysator. 423938032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 424038032Speter recipient mailer has the F=9 flag set, and only works on 424138032Speter text/plain body types. Code contributed by Marius Olafsson 424238032Speter of the University of Iceland. 424338032Speter Special case "postmaster" name so that it is always treated as lower 424438032Speter case in alias files regardless of configuration settings; 424538032Speter this prevents some potential problems where "Postmaster" or 424638032Speter "POSTMASTER" might not match "postmaster". In most cases 424738032Speter this change is a no-op. 424838032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 424938032Speter Costales. 425038032Speter The -a map flag was ignored for dequote maps. Problem noted by 425138032Speter Bryan Costales. 425238032Speter Fix core dump when a lookup of a class "prog" map returns no 425338032Speter response. Patch from Bryan Costales. 425438032Speter Log instances where sendmail is deferring or rejecting connections 425538032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 425638032Speter Include port number in process title for network daemons. Suggested 425738032Speter by Kyle Jones of UUNET. 425838032Speter Send ``double bounces'' (errors that occur when sending an error 425938032Speter message) to the address indicated in the DoubleBounceAddress 426038032Speter option (default: postmaster). Previously they were always 426138032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 426238032Speter Add new mode, -bD, that acts like -bd in all respects except that 426338032Speter it runs in foreground. This is useful for using with a 426438032Speter wrapper that "watches" system services. Suggested by Kyle 426538032Speter Jones of UUNET. 426638032Speter Fix botch in spacing around (parenthesized) comments in addresses 426738032Speter when the comment comes before the address. Patch from 426838032Speter Motonori Nakamura of Kyoto University. 426938032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 427038032Speter that are being bounced to postmaster, rather than "Returned 427138032Speter mail". This permits the person who is postmaster more 427238032Speter easily determine what messages are to their role as 427338032Speter postmaster versus bounces to mail they actually sent. Based 427438032Speter on a suggestion by Motonori Nakamura. 427538032Speter Add new value "time" for QueueSortOrder option; this causes the queue 427638032Speter to be sorted strictly by the time of submission. Note that 427743730Speter this can cause very bad behavior over slow lines (because 427838032Speter large jobs will tend to delay small jobs) and on nodes with 427938032Speter heavy traffic (because old things in the queue for hosts that 428038032Speter are down delay processing of new jobs). Also, this does not 428138032Speter guarantee that jobs will be delivered in submission order 428238032Speter unless you also set DeliveryMode=queue. In general, it should 428338032Speter probably only be used on the command line, and only in 428438032Speter conjunction with -qRhost.domain. In fact, there are very few 428538032Speter cases where it should be used at all. Based on an 428638032Speter implementation by Motonori Nakamura. 428738032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 428838032Speter the same manner as other rulesets. Previously a temporary 428938032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 429038032Speter of Stanford University. 429138032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 429238032Speter 5yz (permanent failure) code. The next MX host will still be 429338032Speter tried if the connection cannot be opened in the first place 429438032Speter or if the MAIL command returns a 4yz (temporary failure) code. 429538032Speter (It's hard to know what to do here, since neither RFC 974 nor 429638032Speter RFC 1123 specify when to proceed to the next MX host.) 429738032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 429838032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 429938032Speter This causes map lookups that get a temporary failure (e.g., 430038032Speter name server failure) to _not_ defer the delivery of the 430138032Speter message. This should only be used if your configuration file 430238032Speter is prepared to do something sensible in this case. Based on 430338032Speter an idea by Gregory Shapiro of WPI. 430438032Speter Fix problem finding network interface addresses. Patch from 430538032Speter Motonori Nakamura. 430638032Speter Don't reject qf entries that are not owned by your effective uid if 430780785Sgshapiro you are not running set-user-id; this makes management of 430880785Sgshapiro certain kinds of firewall setups difficult. Patch 430980785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 431038032Speter Add persistent host status. This keeps the information normally 431138032Speter maintained within a single queue run in disk files that are 431238032Speter shared between sendmail instances. The HostStatusDirectory 431338032Speter is the directory in which the information is maintained. If 431438032Speter not set, persistent host status is turned off. If not a full 431538032Speter pathname, it is relative to the queue directory. A common 431638032Speter value is ".hoststat". 431738032Speter There are also two new operation modes: 431838032Speter * -bh prints the status of hosts that have had recent 431938032Speter connections. 432038032Speter * -bH purges the host statuses. No attempt is made to save 432138032Speter recent status information. 432238032Speter This feature was originally written by Paul Vixie of Vixie 432338032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 432438032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 432538032Speter with my insistence that things fit cleanly into the V8 432638032Speter framework is gratefully appreciated. 432738032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 432838032Speter operate). Avoids letting two sendmails on the local machine 432964562Sgshapiro open connections to the same remote host at the same time. 433038032Speter This reduces load on the other machine, but can cause mail to 433138032Speter be delayed (for example, if one sendmail is delivering a huge 433238032Speter message, other sendmails won't be able to send even small 433338032Speter messages). Also, it requires another file descriptor (for the 433438032Speter lock file) per connection, so you may have to reduce 433538032Speter ConnectionCacheSize to avoid running out of per-process 433638032Speter file descriptors. Based on the persistent host status code 433738032Speter contributed by Paul Vixie and Mark Lovell. 433838032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 433938032Speter SafeFileEnvironment option is set. Problem noted by Bryan 434038032Speter Costales. 434138032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 434238032Speter file. Problem noted by Bryan Costales. 434338032Speter If a job was aborted using the interrupt signal (e.g., control-C from 434438032Speter the keyboard), on some occasions an empty df file would be 434538032Speter left around; these would collect in the queue directory. 434638032Speter Problem noted by Bryan Costales. 434738032Speter Change the makesendmail script to enhance the search for Makefiles 434838032Speter based on release number. For example, on SunOS 5.5.1, it will 434938032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 435038032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 435138032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 435238032Speter Webmasters. 435338032Speter When creating maps using "newaliases", always map the keys to lower 435438032Speter case when creating the map unless the -f flag is specified on 435538032Speter the map itself. Previously this was done based on the F=u 435638032Speter flag in the local mailer, which meant you could create aliases 435738032Speter that you could never access. Problem noted by Bob Wu of DEC. 435838032Speter When a job was read from the queue, the bits causing notification on 435938032Speter failure or delay were always set. This caused those 436038032Speter notifications to be sent even if NOTIFY=NEVER had been 436138032Speter specified. Problem noted by Steve Hubert of the University 436238032Speter of Washington, Seattle. 436338032Speter Add new configurable routine validate_connection (in conf.c). This 436438032Speter lets you decide if you are willing to accept traffic from 436538032Speter this host. If it returns FALSE, all SMTP commands will return 436638032Speter "550 Access denied". -DTCPWRAPPERS will include support for 436738032Speter TCP wrappers; you will need to add -lwrap to the link line. 436838032Speter (See src/READ_ME for details.) 436938032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 437038032Speter bounces. Some people seemed to think that this could be 437138032Speter confusing (even though it is true). Suggested by Motonori 437238032Speter Nakamura. 437338032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 437438032Speter user early in processing to avoid potential security problems. 437538032Speter However, this means that all .forward and :include: files must 437638032Speter be readable by that user, and all files to be written must be 437738032Speter writable by that user and all programs will be executed by that 437838032Speter user. It is also incompatible with the SafeFileEnvironment 437938032Speter option. In other words, it may not actually add much to 438038032Speter security. However, it should be useful on firewalls and other 438138032Speter places where users don't have accounts and the aliases file is 438238032Speter well constrained. 438338032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 438438032Speter only on the first attempt to delivery to an address. It could 438538032Speter be set to be lower than Timeout.connect on the principle that 438638032Speter the mail should go through quickly to responsive hosts; less 438738032Speter responsive hosts get to wait for the next queue run. 438838032Speter Fix a problem on Solaris that occasionally causes programs 438938032Speter (such as vacation) to hang with their standard input connected 439038032Speter to a UDP port. It also created some signal handling problems. 439138032Speter The problems turned out to be an interaction between vfork(2) 439238032Speter and some of the libraries, particularly NIS/NIS+. I am 439338032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 439438032Speter Change user class map to do the same matching that actual delivery 439538032Speter will do instead of just a /etc/passwd lookup. This adds 439638032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 439738032Speter The Timeout.* options are not safe -- they can be used to create a 439838032Speter denial-of-service attack. Problem noted by Christophe 439938032Speter Wolfhugel. 440043730Speter Don't send PostmasterCopy messages in the event of a "delayed" 440138032Speter notification. Suggested by Barry Bouwsma. 440238032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 440338032Speter option is set, since this disables VERB mode. Suggested 440438032Speter by John Hawkinson of MIT. 440538032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 440638032Speter by Motonori Nakamura of Kyoto University. 440738032Speter Only queue messages on transient .forward open failures if there 440843730Speter were no successful opens. The previous behavior caused it 440938032Speter to queue even if a "fall back" .forward was found. Problem 441038032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 441138032Speter and Computer Science (DISCS), NUS, Singapore. 441238032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 441338032Speter is bouncing because of a MIME error during 8->7 bit conversion; 441438032Speter the encapsulated message will bounce again, causing a loop. 441538032Speter Problem noted by Steve Hubert of the University of Washington. 441638032Speter Create xf (transcript) files using the TempFileMode option value 441738032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 441838032Speter National University of Singapore. 441938032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 442038032Speter detect cases where DefaultUid is set to something that the 442138032Speter system can't cope with. 442238032Speter PORTABILITY FIXES: 442338032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 442438032Speter Atlas International. 442538032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 442638032Speter <bicknell@ufp.org>. 442738032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 442838032Speter work on the first recipient of a message due to a 442938032Speter bug in the getpwent family.

Based on a patch from Randall 447238032Speter Winchester of the University of Maryland. 447338032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 447438032Speter Robert La Ferla of Hot Software. 447538032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 447638032Speter (where "code" is an exit status) on domains (previously 447738032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 447838032Speter Foundation. 447938032Speter CONFIG: hooks for IPv6-style domain literals. 448038032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 448138032Speter if it is undefined the AliasFile option is never set; this 448238032Speter should be transparent for most everyone. Suggested by John 448338032Speter Myers of CMU. 448438032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 448538032Speter domain listed in $=w is masqueraded. With it, only those 448638032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 448738032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 448838032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 448938032Speter hosts under those domains as well as the domain headers 449038032Speter themselves. For example, if a configuration had 449138032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 449238032Speter foo.com would be masqueraded; with it, *.foo.com would be 449338032Speter masqueraded as well. Based on an implementation by Richard 449438032Speter (Pug) Bainter of U. Texas. 449538032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 449638032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 449738032Speter Keys are user names; values are outgoing mail addresses. Yes, 449838032Speter this does overlap with the user database, and figuring out 449938032Speter just when to use which one may be tricky. Based on code 450038032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 450138032Speter from Per Hedeland of Ericsson. 450238032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 450338032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 450438032Speter Keys are either fully qualified addresses or just the host 450538032Speter part (with the @ sign). For example, a table containing: 450638032Speter info@foo.com foo-info 450738032Speter info@bar.com bar-info 450838032Speter @baz.org jane@elsewhere.net 450938032Speter would send all mail destined for info@foo.com to foo-info 451038032Speter (which is presumably an alias), mail addressed to info@bar.com 451138032Speter to bar-info, and anything addressed to anyone at baz.org will 451238032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 451338032Speter and baz.org must all be in $=w. Based on discussions with 451438032Speter a great many people. 451538032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 451638032Speter Suggested by Richard Bainter. 451738032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 451838032Speter "fax" mailer. 451938032Speter CONFIG: allow mailertable entries to resolve to local:user; this 452038032Speter passes the original user@host in to procmail-style local 452138032Speter mailers as the "detail" information to allow them to do 452238032Speter additional clever processing. From Joe Pruett of 452338032Speter Teleport Corporation. Delivery to the original user can 452438032Speter be done by specifying "local:" (with nothing after the colon). 452538032Speter CONFIG: allow any context that takes "mailer:domain" to also take 452638032Speter "mailer:user@domain" to force mailing to the given user; 452738032Speter "local:user" can also be used to do local delivery. This 452838032Speter applies on *_RELAY and in the mailertable entries. Based 452938032Speter on a suggestion by Ribert Kiessling of Easynet. 453038032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 453138032Speter limits the possible domains; this reduces the number of DNS 453238032Speter lookups required to support this feature. For example, 453338032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 453438032Speter to domains under my.site.com. Code contributed by Anthony 453538032Speter Thyssen <anthony@cit.gu.edu.au>. 453638032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 453738032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 453838032Speter of WPI. 453938032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 454038032Speter event you have to define local mailers. Suggested by 454138032Speter Gregory Shapiro of WPI. 454238032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 454338032Speter be misinterpreted as a list:...; syntax. Based on a patch by 454438032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 454538032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 454638032Speter remotely connected. The address host!user was being 454738032Speter converted to host!user@thishost instead of host!user@uurelay. 454838032Speter Problem noted by William Gianopoulos of Raytheon Company. 454938032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 455038032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 455138032Speter "User has moved"; the former wording was confusing if the 455238032Speter new address is still on the local host. Based on a suggestion 455338032Speter by Andreas Luik. 455438032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 455538032Speter However, the class is not pre-initialized to contain root. 455638032Speter Suggested by Gregory Neil Shapiro. 455738032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 455838032Speter Wolfhugel. 455938032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 456038032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 456138032Speter well: this produces a slightly different mailbox format (no 456238032Speter Content-Length: headers), file ownerships and modes are 456338032Speter different (not owned by group mail; mode 600 instead of 660), 456438032Speter and the local mailer flags will have to be tweaked (make them 456538032Speter match bsd4.4) in order to use this mailer. Patches from Paul 456638032Speter Hammann of the Missouri Research and Education Network. 456738032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 456838032Speter was a delivery error, such as if the ownership on the file 456938032Speter was wrong or the mode changed between the initial stat and 457038032Speter the open. Problem reported by William Colburn of the New 457138032Speter Mexico Institute of Mining and Technology. 457238032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 457338032Speter Costales. 457438032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 457538032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 457638032Speter honored. Fix from Michael Scott Shappe. 457738032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 457838032Speter NEW FILES: 457938032Speter src/Makefiles/Makefile.AIX.2 458038032Speter src/Makefiles/Makefile.IRIX.6.2 458138032Speter src/Makefiles/Makefile.maxion 458238032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 458338032Speter src/Makefiles/Makefile.SCO.5.x 458438032Speter src/Makefiles/Makefile.UXPDSV20 458538032Speter mailstats/mailstats.8 458638032Speter praliases/praliases.8 458738032Speter cf/cf/generic-nextstep3.3.mc 458838032Speter cf/feature/genericstable.m4 458938032Speter cf/feature/limited_masquerade.m4 459038032Speter cf/feature/masquerade_entire_domain.m4 459138032Speter cf/feature/virtusertable.m4 459238032Speter cf/ostype/aix2.m4 459338032Speter cf/ostype/altos.m4 459438032Speter cf/ostype/maxion.m4 459538032Speter cf/ostype/solaris2.ml.m4 459638032Speter cf/ostype/uxpds.m4 459738032Speter contrib/re-mqueue.pl 459838032Speter DELETED FILES: 459938032Speter src/Makefiles/Makefile.Solaris 460038032Speter contrib/xla/README 460138032Speter contrib/xla/xla.c 460238032Speter RENAMED FILES: 460338032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 460438032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 460538032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 460638032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 460738032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 460838032Speter 460964562Sgshapiro8.7.6/8.7.3 1996/09/17 461038032Speter SECURITY: It is possible to force getpwuid to fail when writing the 461138032Speter queue file, causing sendmail to fall back to running programs 461238032Speter as the default user. This is not exploitable from off-site. 461338032Speter Workarounds include using a unique user for the DefaultUser 461438032Speter (old u & g options) and using smrsh as the local shell. 461538032Speter SECURITY: fix some buffer overruns; in at least one case this allows 461638032Speter a local user to get root. This is not known to be exploitable 461738032Speter from off-site. The workaround is to disable chfn(1) commands. 461838032Speter 461964562Sgshapiro8.7.5/8.7.3 1996/03/04 462038032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 462138032Speter in some case cause connections to hang or messages to have 462238032Speter extra spaces in odd places. Patch from Eric Wassenaar; 462338032Speter reports from Eric Hall of Chiron Corporation, Stephen 462438032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 462538032Speter and others. 462638032Speter 462764562Sgshapiro8.7.4/8.7.3 1996/02/18 462838032Speter SECURITY: In some cases it was still possible for an attacker to 462938032Speter insert newlines into a queue file, thus allowing access to 463038032Speter any user (except root). 463138032Speter CONFIG: no changes -- it is not a bug that the configuration 463238032Speter version number is unchanged. 463338032Speter 463464562Sgshapiro8.7.3/8.7.3 1995/12/03 463538032Speter Fix botch in name server timeout in RCPT code; this problem caused 463638032Speter two responses in SMTP, which breaks things horribly. Fix 463738032Speter from Gregory Neil Shapiro of WPI. 463838032Speter Verify that L= value on M lines cannot be negative, which could cause 463938032Speter negative array subscripting. Not a security problem since 464038032Speter this has to be in the config file, but it could have caused 464138032Speter core dumps. Pointed out by Bryan Costales. 464238032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 464338032Speter Costales. 464438032Speter PORTABILITY FIXES: 464538032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 464638032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 464738032Speter order. Tweak it to work properly. Based on fixes 464838032Speter from Fletcher Mattox of UTexas and Betty Lee of 464938032Speter Stanford University. 465038032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 465138032Speter Deficiency pointed out by Bryan Costales of ICSI. 465238032Speter 465364562Sgshapiro8.7.2/8.7.2 1995/11/19 465438032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 465538032Speter OperatorChars, and UnixFromLine options. They were not 465638032Speter properly repaired in 8.7.1. 465738032Speter Completely delete the Bcc: header if and only if there are other 465838032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 465938032Speter last being a historic botch, of course). If Bcc: is the 466038032Speter only recipient header in the message, its value is tossed, 466143730Speter but the header name is kept. The old behavior (always keep 466238032Speter the header name and toss the value) allowed primary recipients 466338032Speter to see that a Bcc: went to _someone_. 466438032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 466538032Speter sender to <address> using -f'' syslog messages. Suggested 466638032Speter by Kari Hurtta. 466738032Speter If a sequence or switch map lookup entry gets a tempfail but then 466838032Speter continues on to another map type, but the name is not found, 466938032Speter return a temporary failure from the sequence or switch map. 467038032Speter For example, if hosts search ``dns files'' and DNS fails 467138032Speter with a tempfail, the hosts map will go on and search files, 467238032Speter but if it fails the whole thing should be a tempfail, not 467338032Speter a permanent (host unknown) failure, even though that is the 467438032Speter failure in the hosts.files map. This error caused hard 467538032Speter bounces when it should have requeued. 467638032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 467780785Sgshapiro owned by bar mode 700 and inbox being set-user-id bar stopped 467838032Speter working properly due to excessive paranoia. Pointed out by 467938032Speter John Hawkinson of Panix. 468038032Speter An SMTP RCPT command referencing a host that gave a nameserver 468138032Speter timeout would return a 451 command (8.6 accepted it and 468243730Speter queued it locally). Revert to the 8.6 behavior in order 468338032Speter to simplify queue management for clustered systems. Suggested 468438032Speter by Gregory Neil Shapiro of WPI. The same problem could break 468538032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 468638032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 468738032Speter Infobiogen. 468838032Speter Fix possible buffer overflow in munchstring(). This was not a security 468938032Speter problem because you couldn't specify any argument to this 469038032Speter without first giving up root privileges, but it is still a 469138032Speter good idea to avoid future problems. Problem noted by John 469238032Speter Hawkinson and Sam Hartman of MIT. 469338032Speter ``452 Out of disk space for temp file'' messages weren't being 469438032Speter printed. Fix from David Perlin of Nanosoft. 469543730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 469638032Speter is not set, since this is required to get the actual DSNs 469738032Speter created. Problem pointed out by John Gardiner Myers of CMU. 469838032Speter Log permission problems that cause .forward and :include: files to 469938032Speter be untrusted or ignored on log level 12 and higher. Suggested 470038032Speter by Randy Martin of Clemson University. 470138032Speter Allow user ids in U= clauses of M lines to have hyphens and 470238032Speter underscores. 470338032Speter Fix overcounting of recipients -- only happened when sending to an 470438032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 470538032Speter of Systems and Computer Technology Corporation. 470638032Speter If a message is sent to an address that fails, the error message that 470738032Speter is returned could show some extraneous "success" information 470838032Speter included even if the user did not request success notification, 470938032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 471038032Speter Config files that had no AliasFile definition were defaulting to 471138032Speter using /etc/aliases; this caused problems with nullclient 471238032Speter configurations. Change it back to the 8.6 semantics of 471338032Speter having no local alias file unless it is declared. Problem 471438032Speter noted by Charles Karney of Princeton University. 471538032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 471638032Speter Costales of ICSI. 471738032Speter Map lookups of class "userdb" maps were always case sensitive; they 471838032Speter should be controlled by the -f flag like other maps. Pointed 471938032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 472038032Speter Fix problem that caused some addresses to be passed through ruleset 5 472138032Speter even when they were tagged as "sticky" by prefixing the 472238032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 472338032Speter Technological University. 472438032Speter When converting a message to Quoted-Printable, prevent any lines with 472538032Speter dots alone on a line by themselves. This is because of the 472638032Speter preponderance of broken mailers that still get this wrong. 472738032Speter Code contributed by Per Hedeland of Ericsson. 472838032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 472938032Speter out by Bjart Kvarme of USIT/UiO (Norway). 473038032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 473138032Speter Requested by Allan Johannesen. 473238032Speter Delete check for text format of alias files -- it should be legal 473338032Speter to have the database format of the alias files without the 473438032Speter text version. Problem pointed out by Joe Rhett of Navigist, 473538032Speter Inc. 473638032Speter If "Ot" was specified with no value, the TZ variable was not properly 473738032Speter imported from the environment. Pointed out by Frank Crawford 473838032Speter <frank@ansto.gov.au>. 473938032Speter Some architectures core dumped on "program" maps that didn't have 474038032Speter extra arguments. Patch from Booker C. Bense of Stanford 474138032Speter University. 474238032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 474338032Speter the parent should do this. Fix from Brian Coan of the 474438032Speter Association for Progressive Communications. 474538032Speter If MinQueueAge was set and a message was considered but not run 474638032Speter during a queue run and the Timeout.queuereturn interval was 474738032Speter reached, a "timed out" error message would be returned that 474838032Speter didn't include the failed address (and claimed to be a warning 474938032Speter even though it was fatal). The fix is to not return such 475038032Speter messages until they are actually tried, i.e., in the next 475138032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 475238032Speter SINTEF RUNIT, Oslo. 475338032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 475438032Speter that have the hes_getmailhost() routine.

Bug 480138032Speter pointed out by John Hawkinson of MIT. 480238032Speter Fix strange case of an executable called by a program map that 480338032Speter returns a value but also a non-zero exit status; this 480438032Speter would give contradictory results in the higher level; in 480538032Speter particular, the default clause in the map lookup would be 480638032Speter ignored. Change to ignore the value if the program returns 480738032Speter non-zero exit status. From Tom Moore of AT&T GIS. 480838032Speter Shorten parameters passed to syslog() in some contexts to avoid a 480938032Speter bug in many vendors' implementations of that routine. Although 481038032Speter this isn't really a bug in sendmail per se, and my solution 481138032Speter has to assume that syslog() has at least a 1K buffer size 481238032Speter internally (I know some vendors have shortened this 481338032Speter dramatically -- they're on their own), sendmail is a popular 481438032Speter target. Also, limit the size of %s arguments in sprintf. 481538032Speter These both have possible security implications. Solutions 481638032Speter suggested by Casper Dik of Sun's Network Security Group 481738032Speter (Holland), Mark Seiden, and others. 481838032Speter Fix a problem that might cause a non-standard -B (body type) 481938032Speter parameter to be passed to the next server with undefined 482038032Speter results. This could have security implications. 482138032Speter If a filesystem was at > 100% utilization, the freediskspace() 482238032Speter routine incorrectly returned an error rather than zero. 482338032Speter Problem noted by G. Paul Ziemba of Alantec. 482438032Speter Change MX sort order so that local hostnames (those in $=w) always 482538032Speter sort first within a given preference. This forces the bestmx 482638032Speter map to always return the local host first, if it is included 482738032Speter in the list of highest priority MX records. From K. Robert 482838032Speter Elz. 482938032Speter Avoid some possible null pointer dereferences. Fixes from Randy 483038032Speter Martin <WOLF@CLEMSON.EDU> 483138032Speter When sendmail starts up on systems that have no fully qualified 483238032Speter domain name (FQDN) anywhere in the first matching host map 483338032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 483438032Speter sendmail would sleep to try to find a FQDN, which it really 483538032Speter really needs. This has been changed to fall through to the 483638032Speter next map type if it can't find a FQDN -- i.e., if the hosts 483738032Speter file doesn't have a FQDN, it will try dns even though the 483838032Speter short name was found in /etc/hosts. This is probably a crock, 483938032Speter but many people have hosts files without FQDNs. Remember: 484038032Speter domain names are your friends. 484138032Speter Log a high-priority message if you can't find your FQDN during startup. 484238032Speter Suggested by Simon Barnes of Schlumberger Limited. 484338032Speter When using Hesiod, initialize it early to improve error reporting. 484438032Speter Patch from Don Lewis of Silicon Systems, Inc. 484538032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 484638032Speter connection timeout in the kernel. Add a new "connect" timeout 484738032Speter to limit this time. Defaults to zero (use whatever the 484838032Speter kernel provides). Based on code contributed by J.R. Oldroyd 484938032Speter of TerraNet. 485038032Speter Under some circumstances, a failed message would not be properly 485138032Speter removed from the queue, causing tons of bogus error messages. 485238032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 485338032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 485438032Speter of WPI. 485538032Speter PORTABILITY FIXES: 485638032Speter On IRIX 5.x, there was an inconsistency in the setting 485738032Speter of sendmail.st location. Change the Makefile to 485838032Speter install it in /var/sendmail.st to match the OSTYPE 485938032Speter file and SGI standards.

Suggested by Per Hedeland of Ericsson. 487338032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 487438032Speter otherwise the F=S causes the From_ line to imply that root is 487538032Speter the sender. Problem pointed out by Claude Scarpelli of 487638032Speter Infobiogen (France). 487738032Speter NEW FILES: 487838032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 487938032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 488038032Speter src/Makefiles/Makefile.UXPDS 488138032Speter 488264562Sgshapiro8.7/8.7 1995/09/16 488338032Speter Fix a problem that could cause sendmail to run out of file 488438032Speter descriptors due to a trashed data structure after a 488538032Speter vfork.

This was used "safely" in the sense 489138032Speter that it only did a stat, but it would have set the 489238032Speter map modification time improperly. Problem pointed out 489338032Speter by Roy Mongiovi of Georgia Tech. 489438032Speter Clean up the Subject: line on warning messages and return 489538032Speter receipts so that they don't say "Returned mail:"; this 489638032Speter can be confusing. 489738032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 489838032Speter useful enough to make it worthwhile printing on "-d". 489938032Speter Avoid logging alias statistics every time you read the alias 490038032Speter file on systems with no database method compiled in. 490138032Speter If you have a name with a trailing dot, and you try looking it 490238032Speter up using gethostbyname without the dot (for /etc/hosts 490338032Speter compatibility), be sure to turn off RES_DEFNAMES and 490438032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 490538032Speter Problem noted by Charles Amos of the University of 490638032Speter Maryland. 490738032Speter Don't do timeouts in collect if you are not running SMTP. 490838032Speter There is nothing that says you can't have a long 490938032Speter running program piped into sendmail (possibly via 491038032Speter /bin/mail, which just execs sendmail). Problem reported 491138032Speter by Don "Truck" Lewis of Silicon Systems. 491238032Speter Try gethostbyname() even if the DNS lookup fails iff option I 491338032Speter is not set. This allows you to have hosts listed in 491438032Speter NIS or /etc/hosts that are not known to DNS. It's normally 491538032Speter a bad idea, but can be useful on firewall machines. This 491638032Speter should really be broken out on a separate flag, I suppose. 491738032Speter Avoid compile warnings against BIND 4.9.3, which uses function 491838032Speter prototypes.

From Kyle Jones of UUNET. 492338032Speter SECURITY: avoid denial-of-service attacks possible by destroying 492438032Speter the alias database file by setting resource limits low. 492538032Speter This involves adding two new compile-time options: 492638032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 492738032Speter available) and HASULIMIT (indicating that ulimit(2) support 492838032Speter is available -- the Release 3 form is used). The former 492938032Speter is assumed on BSD-based systems, the latter on System 493038032Speter V-based systems. Attack noted by Phil Brandenberger of 493138032Speter Swarthmore University. 493238032Speter New syntaxes in test (-bt) mode: 493338032Speter ``.Dmvalue'' will define macro "m" to "value". 493438032Speter ``.Ccvalue'' will add "value" to class "c". 493538032Speter ``=Sruleset'' will dump the contents of the indicated 493638032Speter ruleset. 493738032Speter ``=M'' will display the known mailers. 493838032Speter ``-ddebug-spec'' is equivalent to the command-line 493938032Speter -d debug flag. 494038032Speter ``$m'' will print the value of macro $m. 494138032Speter ``$=c'' will print the contents of class $=c. 494238032Speter ``/mx host'' returns the MX records for ``host''. 494338032Speter ``/parse address'' will parse address, returning the value of 494438032Speter crackaddr (essentially, the comment information) 494538032Speter and the parsed address. 494638032Speter ``/try mailer address'' will rewrite address into the form 494738032Speter it will have when presented to the indicated mailer. 494838032Speter ``/tryflags flags'' will set flags used by parsing. The 494938032Speter flags can be `H' for header or `E' for envelope, 495038032Speter and `S' for sender or `R' for recipient. These 495138032Speter can be combined, so `HR' sets flags for header 495238032Speter recipients. 495338032Speter ``/canon hostname'' will try to canonify hostname and 495438032Speter return the result. 495538032Speter ``/map mapname key'' will look up `key' in the indicated 495638032Speter `mapname' and return the result. 495738032Speter Somewhat better handling of UNIX-domain socket addresses -- it 495838032Speter should show the pathname rather than hex bytes. 495938032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 496038032Speter the header for envelope sender information and uses 496138032Speter CR-LF as message terminators. It was thought to be 496238032Speter obsolete (used only for Arpanet NCP protocols), but it 496338032Speter turns out that the UK ``Grey Book'' protocols require 496438032Speter that functionality. 496538032Speter Fix a fix in previous release -- if gethostname and gethostbyname 496638032Speter return a name without dots, and if an attempt to canonify 496738032Speter that name fails, wait one minute and try again. This can 496838032Speter result in an extra 60 second delay on startup if your system 496938032Speter hostname (as returned by hostname(1)) has no dot and no names 497038032Speter listed in /etc/hosts or your NIS map have a dot. 497138032Speter Check for proper domain name on HELO and EHLO commands per 497238032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 497338032Speter of Michigan Technological University. 497438032Speter Relax chownsafe rules slightly -- old version said that if you 497538032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 497638032Speter if fpathconf returned EINVAL or ENOSYS), assume that 497738032Speter chown is not safe. The new version falls back to whether 497838032Speter you are on a BSD system or not. This is important for 497938032Speter SunOS, which apparently always returns one of those 498038032Speter error codes. This impacts whether you can mail to files 498138032Speter or not. 498238032Speter Syntax errors such as unbalanced parentheses in the configuration 498338032Speter file could be omitted if you had "Oem" prior to the 498438032Speter syntax error in the config file. Change to always print 498538032Speter the error message. It was especially weird because it 498638032Speter would cause a "warning" message to be sent to the Postmaster 498738032Speter for every message sent (but with no transcript). Problem 498838032Speter noted by Gregory Paris of Motorola. 498938032Speter Rewrite collect and putbody to handle full 8-bit data, including 499038032Speter zero bytes.

This is to handle the 505938032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 506038032Speter assume that ``group name:'' is a comment on the first 506138032Speter address and the ``;'' is a comment on the last address). 506238032Speter This requires config file support to get right. It does 506338032Speter understand that :: is NOT this syntax, and can be turned 506438032Speter off completely by setting the ColonOkInAddresses option. 506538032Speter Level 6 config files added with new mailer flags: 506638032Speter A Addresses are aliasable. 506738032Speter i Do udb rewriting on envelope as well as header 506838032Speter sender lines. Applies to the from address mailer 506938032Speter flags rather than the recipient mailer flags. 507038032Speter j Do udb rewriting on header recipient addresses. 507138032Speter Applies to the sender mailer flags rather than the 507238032Speter recipient mailer flags. 507338032Speter k Disable check for loops when doing HELO command. 507438032Speter o Always run as the mail recipient, even on local 507538032Speter delivery. 507638032Speter w Check for an /etc/passwd entry for this user. 507738032Speter 5 Pass addresses through ruleset 5. 507838032Speter : Check for :include: on this address. 507938032Speter | Check for |program on this address. 508038032Speter / Check for /file on this address. 508138032Speter @ Look up sender header addresses in the user 508238032Speter database. Applies to the mailer flags for the 508338032Speter mailer corresponding to the envelope sender 508438032Speter address, rather than to recipient mailer flags. 508538032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 508638032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 508738032Speter mailers, and the ColonOkInAddresses option. 508838032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 508938032Speter John Beck of Hewlett-Packard, who generously contributed 509038032Speter their implementation to me, which I then didn't use (see 509138032Speter mime.c for an explanation of why). This adds the 509238032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 509338032Speter to control handling of 8-bit data. These have to cope with 509438032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 509538032Speter 8-bit data that is entered without declaring it as 8-bit 509638032Speter MIME -- technically this is illegal according to the 509738032Speter specs) and labelled 8-bit data (that is, it was declared 509838032Speter as 8BITMIME in the ESMTP session or by using the 509938032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 510038032Speter set then 8-bit data is sent to non-8BITMIME machines 510138032Speter instead of converting to 7 bit (essentially using 510238032Speter just-send-8 semantics). The values for EightBitMode are: 510338032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 510438032Speter any necessary conversion of 8BITMIME to 7BIT 510538032Speter (essentially, the full MIME option). 510638032Speter p pass unlabelled 8-bit input, but convert labelled 510738032Speter 8BITMIME input to 7BIT as required (default). 510838032Speter s strict adherence: reject unlabelled 8-bit input, 510938032Speter convert 8BITMIME to 7BIT as required. The F=8 511038032Speter flag is ignored. 511138032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 511238032Speter the setting of F=8. 511338032Speter Add new internal class 'n', which is the set of MIME Content-Types 511438032Speter which can not be 8 to 7 bit encoded because of other 511538032Speter considerations. Types "multipart/*" and "message/*" are 511638032Speter never directly encoded (although their components can be). 511738032Speter Add new internal class 's', which is the set of subtypes of the 511838032Speter MIME message/* content type that can be treated as though 511938032Speter they are an RFC822 message. It is predefined to have 512038032Speter "rfc822". Suggested By Kari Hurtta. 512138032Speter Add new internal class 'e'. This is the set of MIME 512238032Speter Content-Transfer-Encodings that can be converted to 512338032Speter a seven bit format (Quoted-Printable or Base64). It is 512438032Speter preinitialized to contain "7bit", "8bit", and "binary". 512538032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 512638032Speter short name) to set the default character set to use in the 512738032Speter Content-Type: header when doing encoding of an 8-bit message 512838032Speter which isn't marked as MIME into MIME format. If the C= 512938032Speter parameter is set on the Envelope From address, use that as 513038032Speter the default encoding; else use the DefaultCharSet option. 513138032Speter If neither is set, it defaults to "unknown-8bit" as 513238032Speter suggested by RFC 1428 section 3. 513338032Speter Allow ``U=user:group'' field in mailer definition to set a default 513438032Speter user and group that a mailer will be executed as. This 513538032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 513638032Speter also set, it is the uid/gid that will always be used (that 513738032Speter is, the controlling address is ignored). The values may be 513838032Speter numeric or symbolic; if only a symbolic user is given (no 513938032Speter group) that user's default group in the passwd file is used 514038032Speter as the group. Based on code donated by Chip Rosenthal of 514138032Speter Unicom. 514238032Speter Allow `u' option to also accept user:group as a value, in the same 514338032Speter fashion as the U= mailer option. 514438032Speter Add the symbolic time zone name in the Arpanet format dates (as 514538032Speter a comment). This adds a new compile-time configuration 514638032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 514738032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 514838032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 514938032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 515038032Speter timezone()), or TZ_NONE (don't include the comment). Code 515138032Speter from Chip Rosenthal. 515238032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 515338032Speter For example, 515438032Speter O Timeout.helo = 2m 515538032Speter There are also two new suboptions "queuereturn" and 515638032Speter "queuewarn"; these subsume the old T option. Thus, to 515738032Speter set them both the preferred new syntax is 515838032Speter O Timeout.queuereturn = 5d 515938032Speter O Timeout.queuewarn = 4h 516038032Speter Sort queue by host name instead of by message priority if the 516138032Speter QueueSortOrder option (no short name) is set is set to 516238032Speter ``host''. This makes better use of the connection cache, 516338032Speter but may delay more ``interactive'' messages behind large 516438032Speter backlogs under some circumstances. This is probably a 516538032Speter good option if you have high speed links or don't do lots 516638032Speter of ``batch'' messages, but less good if you are using 516738032Speter something like PPP on a 14.4 modem. Based on code 516838032Speter contributed by Roy Mongiovi of Georgia Tech (my main 516938032Speter contribution was to make it configurable). 517038032Speter Save i-number of df file in qf file to simplify rebuilding of queue 517138032Speter after disastrous disk crash. Suggested by Kyle Jones of 517238032Speter UUNET; closely based on code from KJS DECWRL code written 517338032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 517438032Speter are NOT back compatible with 8.6 -- that is, you can convert 517538032Speter from 8.6 to 8.7, but not the other direction. 517638032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 517738032Speter route-addrs in envelopes; this is because in some cases 517838032Speter they can be sent to the shell, which interprets them as 517938032Speter I/O redirection. 518038032Speter Don't include error file (option E) with return-receipts; this 518138032Speter can be confusing. 518238032Speter Don't send "Warning: cannot send" messages to owner-* or 518338032Speter *-request addresses. Suggested by Christophe Wolfhugel 518438032Speter of the Institut Pasteur, Paris. 518538032Speter Allow -O command line flag to set long form options. 518638032Speter Add "MinQueueAge" option to set the minimum time between attempts 518738032Speter to run the queue. For example, if the queue interval 518838032Speter (-q value) is five minutes, but the minimum queue age 518938032Speter is fifteen minutes, jobs won't be tried more often than 519038032Speter once every fifteen minutes. This can be used to give 519138032Speter you more responsiveness if your delivery mode is set to 519238032Speter queue-only. 519338032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 519438032Speter :include: and .forward files. 519538032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 519638032Speter key field name, the value field name, and the field 519738032Speter delimiter. The field delimiter can be a single character 519838032Speter or the sequence "\t" or "\n" for tab or newline. 519938032Speter These are for use by NIS+ and similar access methods. 520038032Speter Change maps to always strip quotes before lookups; the -q flag 520143730Speter turns off this behavior. Suggested by Motonori Nakamura. 520238032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 520338032Speter key and value field names respectively. Code donated by 520438032Speter Sun Microsystems. 520538032Speter Add "hesiod" map class. The "file name" is used as the 520638032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 520738032Speter first value found for the match. Code donated by Scott 520838032Speter Hutton of Indiana University. 520938032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 521038032Speter specify the name of the property that is searched as the 521138032Speter key and a -v flag to specify the name of the property that 521238032Speter is returned as the value (defaults to "members"). The 521338032Speter default map is "/aliases". Some code based on code 521438032Speter contributed by Robert La Ferla of Hot Software. 521538032Speter Add "text" map class. This does slow, linear searches through 521638032Speter text files. The -z flag specifies a column delimiter 521738032Speter (defaults to any sequence of white space), the -k flag 521838032Speter sets the key column number, and the -v flag sets the 521938032Speter value column number. Lines beginning with `#' are treated 522038032Speter as comments. 522138032Speter Add "program" map class to execute arbitrary programs. The search 522238032Speter key is presented as the last argument; the output is one 522338032Speter line read from the programs standard output. Exit statuses 522438032Speter are from sysexits.h. 522538032Speter Add "sequence" map class -- searches maps in sequence until it 522638032Speter finds a match. For example, the declarations: 522738032Speter Kmap1 ... 522838032Speter Kmap2 ... 522938032Speter Kmapseq sequence map1 map2 523038032Speter defines a map "mapseq" that first searches map1; if the 523138032Speter value is found it is returned immediately, otherwise 523238032Speter map2 is searched and the value returned. 523338032Speter Add "switch" map class. This is much like "sequence" except that 523438032Speter the ordering is fetched from an external file, usually 523538032Speter the system service switch. The parameter is the name of 523638032Speter the service to switch on, and the maps that it will use 523738032Speter are the name of the switch map followed by ".service_type". 523838032Speter For example, if the declaration of the map is 523938032Speter Ksample switch hosts 524038032Speter and the system service switch specifies that hosts are 524138032Speter looked up using dns and nis in that order, then this is 524238032Speter equivalent to 524338032Speter Ksample sequence sample.dns sample.nis 524438032Speter The subordinate maps (sample.*) must already be defined. 524538032Speter Add "user" map class -- looks up users using getpwnam. Takes a 524638032Speter "-v field" flag on the definition that tells what passwd 524738032Speter entry to return -- legal values are name, passwd, uid, gid, 524838032Speter gecos, dir, and shell. Generally expected to be used with 524938032Speter the -m (matchonly) flag. 525038032Speter Add "bestmx" map class -- returns the best MX value for the host 525138032Speter listed as the value. If there are several "best" MX records 525238032Speter for this host, one will be chosen at random. 525338032Speter Add "userdb" map class -- looks up entries in the user database. 525438032Speter The "file name" is actually the tag that will be used, 525538032Speter typically "mailname". If there are multiple entries 525638032Speter matching the name, the one chosen is undefined. 525738032Speter Add multiple queue timeouts (both return and warning). These are 525838032Speter set by the Precedence: or Priority: header fields to one of 525938032Speter three values. If a Priority: is set and has value "normal", 526064562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 526138032Speter used. If no priority is set, the Precedence: is consulted; 526238032Speter if negative, non-urgent timeouts are used; if greater than 526338032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 526438032Speter are used. The timeouts are set by setting the six timeouts 526538032Speter queue{warn,return}.{urgent,normal,non-urgent}. 526638032Speter Fix problem when a mail address is resolved to a $#error mailer 526738032Speter with a temporary failure indication; it works in SMTP, 526838032Speter but when delivering locally the mail is silently discarded. 526938032Speter This patch, from Kyle Jones of UUNET, bounces it instead 527038032Speter of queueing it (queueing is very hard). 527138032Speter When using /etc/hosts or NIS-style lookups, don't assume that 527238032Speter the first name in the list is the best one -- instead, 527338032Speter search for the first one with a dot. For example, if 527438032Speter an /etc/hosts entry reads 527538032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 527638032Speter this change will use the second name as the canonical 527738032Speter machine name instead of the initial, unqualified name. 527838032Speter Change dequote map to replace spaces in quoted text with a value 527938032Speter indicated by the -s flag on the dequote map definition. 528038032Speter For example, ``Mdequote dequote -s_'' will change 528138032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 528238032Speter quoted (because of the space character). Suggested by Dan 528338032Speter Oscarsson for use in X.400 addresses. 528438032Speter Implement long macro names as ${name}; long class names can 528538032Speter be similarly referenced as $={name} and $~{name}. 528638032Speter Definitions are (e.g.) ``D{name}value''. Names that have 528738032Speter a leading lower case letter or punctuation characters are 528838032Speter reserved for internal use by sendmail; i.e., config files 528938032Speter should use names that begin with a capital letter. Based 529038032Speter on code contributed by Dan Oscarsson. 529138032Speter Fix core dump if getgrgid returns a null group list (as opposed 529238032Speter to an empty group list, that is, a pointer to a list 529338032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 529438032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 529538032Speter failed, it called syserr which called newstr which called 529638032Speter xalloc.... The newstr is now avoided for "panic" messages. 529738032Speter Reported by Stuart Kemp of James Cook University. 529838032Speter Improve connection cache timeouts; previously, they were not even 529938032Speter checked if you were delivering to anything other than an 530038032Speter IPC-connected host, so a series of (say) local mail 530138032Speter deliveries could cause cached connections to be open 530238032Speter much longer than the specified timeout. 530338032Speter If an incoming message exceeds the maximum message size, stop 530438032Speter writing the incoming bytes to the queue data file, since 530538032Speter this can fill your mqueue partition -- this is a possible 530638032Speter denial-of-service attack. 530738032Speter Don't reject all numeric local user names unless HESIOD is 530838032Speter defined. It turns out that Posix allows all-numeric 530938032Speter user names. Fix from Tony Sanders of BSDI. 531038032Speter Add service switch support. If the local OS has a service 531138032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 531238032Speter on DEC systems) that will be used; otherwise, it falls back 531338032Speter to using a local mechanism based on the ServiceSwitchFile 531438032Speter option (default: /etc/service.switch). For example, if the 531538032Speter service switch lists "files" and "nis" for the aliases 531638032Speter service, that will be the default lookup order. the "files" 531738032Speter ("local" on DEC) service type expands to any alias files 531838032Speter you listed in the configuration file, even if they aren't 531938032Speter actually file lookups. 532038032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 532138032Speter variable which tells whether or not DNS should be considered 532238032Speter canonical. This is now determined based on whether or not 532338032Speter "dns" is in the service list for "hosts". 532438032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 532538032Speter Status Notifications). DSN notifications override 532638032Speter Return-Receipt-To: headers, which are bogus anyhow -- 532738032Speter support for them has been removed. 532838032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 532938032Speter definitions to define the types used in DSN returns for 533038032Speter MTA names, addresses, and diagnostics respectively. 533138032Speter Extend heuristic to force running in ESMTP mode to look for the 533238032Speter five-character string "ESMTP" anywhere in the 220 greeting 533338032Speter message (not just the second line). This is to provide 533438032Speter better compatibility with other ESMTP servers. 533538032Speter Print sequence number of job when running the queue so you can 533638032Speter easily see how much progress you have made. Suggested 533738032Speter by Peter Wemm of DIALix. 533838032Speter Map newlines to spaces in logged message-ids; some versions of 533938032Speter syslog truncate the rest of the line after newlines. 534038032Speter Suggested by Fletcher Mattox of U. Texas. 534138032Speter Move up forking for job runs so that if a message is split into 534238032Speter multiple envelopes you don't get "fork storms" -- this 534338032Speter also improves the connection cache utilization. 534438032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 534538032Speter the purposes of refusing to send error returns. Suggested 534638032Speter by Motonori Nakamura of Ritsumeikan University. 534738032Speter Relax rules on when a file can be written when referenced from 534838032Speter the aliases file: use the default uid/gid instead of the 534938032Speter real uid/gid. This allows you to create a file owned by 535038032Speter and writable only by the default uid/gid that will work 535180785Sgshapiro all the time (without having the set-user-id bit set). Change 535238032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 535338032Speter Microsystems. 535438032Speter Add "DialDelay" option (no short name) to provide an "extra" 535538032Speter delay for dial on demand systems. If this is non-zero 535638032Speter and a connect fails, sendmail will wait this long and 535738032Speter then try again. If it takes longer than the kernel 535838032Speter timeout interval to establish the connection, this 535938032Speter option can give the network software time to establish 536038032Speter the link. The default units are seconds. 536138032Speter Move logging of sender information to be as early as possible; 536238032Speter previously, it could be delayed a while for SMTP mail 536338032Speter sent to aliases. Suggested by Brad Knowles of the 536438032Speter Defense Information Systems Agency. 536538032Speter Call res_init() before setting RES_DEBUG; this is required by 536638032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 536738032Speter the National Computer Security Center. 536838032Speter Add xdelay= field in logs -- this is a transaction delay, telling 536938032Speter you how long it took to deliver to this address on the 537038032Speter last try. It is intended to be used for sorting mailing 537138032Speter lists to favor "quick" addresses. Provided for use by 537238032Speter the mailprio scripts (see below). 537338032Speter If a map cannot be opened, and that map is non-optional, and 537438032Speter an address requires that map for resolution, queue the 537538032Speter map instead of bouncing it. This involves creating a 537638032Speter pseudo-class of maps called "bogus-map" -- if a required 537738032Speter map cannot be opened, the class is changed to bogus-map; 537838032Speter all queries against bogus-map return "tempfail". The 537938032Speter bogus-map class is not directly accessible. A sample 538038032Speter implementation was donated by Jem Taylor of Glasgow 538138032Speter University Computing Service. 538238032Speter Fix a possible core dump when mailing to a program that talks 538338032Speter SMTP on its standard input. Fix from Keith Moore of 538438032Speter the University of Kentucky. 538538032Speter Make it possible to resolve filenames to $#local $: @ /filename; 538638032Speter previously, the "@" would cause it to not be recognized 538738032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 538838032Speter Accept a -1 signal to re-exec the daemon. This only works if 538938032Speter argv[0] is a full path to sendmail. 539038032Speter Fix bug in "addr=..." field in O option on little-endian machines 539138032Speter -- the network number wasn't being converted to network 539238032Speter byte order. Patch from Kurt Lidl of Pix Technologies 539338032Speter Corporation. 539438032Speter Pre-initialize the resolver early on; this is to avoid a bug with 539538032Speter BIND 4.9.3 that can cause the _res.retry field to get 539638032Speter reset to zero, causing all name server lookups to time 539738032Speter out. Fix from Matt Day of Artisoft. 539838032Speter Restore T line (trusted users) in config file -- but instead of 539938032Speter locking out the -f flag, they just tell whether or not 540038032Speter an X-Authentication-Warning: will be added. This really 540138032Speter just creates new entries in class 't', so "Ft/file/name" 540238032Speter can be used to read trusted user names from a file. 540338032Speter Trusted users are also allowed to execute programs even 540438032Speter if they have a shell that isn't in /etc/shells. 540538032Speter Improve NEWDB alias file rebuilding so it will create them 540638032Speter properly if they do not already exist. This had been 540738032Speter a MAYBENEXTRELEASE feature in 8.6.9. 540838032Speter Check for @:@ entry in NIS maps before starting up to avoid 540938032Speter (but not prevent, sigh) race conditions. This ought to 541038032Speter be handled properly in ypserv, but isn't. Suggested by 541138032Speter Michael Beirne of Motorola. 541238032Speter Refuse connections if there isn't enough space on the filesystem 541338032Speter holding the queue. Contributed by Robert Dana of Wolf 541438032Speter Communications. 541538032Speter Skip checking for directory permissions in the path to a file 541638032Speter when checking for file permissions iff setreuid() 541738032Speter succeeded -- it is unnecessary in that case. This avoids 541838032Speter significant performance problems when looking for .forward 541938032Speter files. Based on a suggestion by Win Bent of USC. 542038032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 542138032Speter arbitrary ruleset number assigned or "Sname = integer" 542238032Speter to assign a specific ruleset number. Reference is 542338032Speter $>name_or_number. Names can be composed of alphas, digits, 542438032Speter underscore, or hyphen (first character must be non-numeric). 542538032Speter Allow -o flag on AliasFile lines to make the alias file optional. 542638032Speter From Bryan Costales of ICSI. 542738032Speter Add NoRecipientAction option to handle the case where there is 542838032Speter no legal recipient header in the message. It can take 542938032Speter on values: 543038032Speter None Leave the message as is. The 543138032Speter message will be passed on even 543238032Speter though it is in technically 543338032Speter illegal syntax. 543438032Speter Add-To Add a To: header with any 543538032Speter recipients that it can find from 543638032Speter the envelope. This risks exposing 543738032Speter Bcc: recipients. 543838032Speter Add-Apparently-To Add an Apparently-To: header. This 543938032Speter has almost no redeeming social value, 544038032Speter and is provided only for back 544138032Speter compatibility. 544238032Speter Add-To-Undisclosed Add a header reading 544338032Speter To: undisclosed-recipients:; 544438032Speter which will have the effect of 544538032Speter making the message legal without 544638032Speter exposing Bcc: recipients. 544738032Speter Add-Bcc To add an empty Bcc: header. 544838032Speter There is a chance that mailers down 544938032Speter the line will delete this header, 545038032Speter which could cause exposure of Bcc: 545138032Speter recipients. 545238032Speter The default is NoRecipientAction=None. 545338032Speter Truncate (rather than delete) Bcc: lines in the header. This 545438032Speter should prevent later sendmails (at least, those that don't 545538032Speter themselves delete Bcc:) from considering this message to 545638032Speter be non-conforming -- although it does imply that non-blind 545738032Speter recipients can see that a Bcc: was sent, albeit not to whom. 545838032Speter Add SafeFileEnvironment option. If declared, files named as delivery 545938032Speter targets must be regular files in addition to the regular 546038032Speter checks. Also, if the option is non-null then it is used as 546138032Speter the name of a directory that is used as a chroot(2) 546238032Speter environment for the delivery; the file names listed in an 546338032Speter alias or forward should include the name of this root. 546438032Speter For example, if you run with 546538032Speter O SafeFileEnvironment=/arch 546638032Speter then aliases should reference "/arch/rest/of/path". If a 546738032Speter value is given, sendmail also won't try to save to 546838032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 546938032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 547038032Speter Support -A flag for alias files; this will comma concatenate like 547138032Speter entries. For example, given the aliases: 547238032Speter list: member1 547338032Speter list: member2 547438032Speter and an alias file declared as: 547538032Speter OAhash:-A /etc/aliases 547638032Speter the final alias inserted will be "list: member1,member2"; 547738032Speter without -A you will get an error on the second and subsequent 547838032Speter alias for "list". Contributed by Bryan Costales of ICSI. 547938032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 548038032Speter Fix a problem that could cause very long addresses to core dump in 548138032Speter some special circumstances. Problem pointed out by Allan 548238032Speter Johannesen. 548338032Speter (Internal change.) Change interface to expand() (macro expansion) 548438032Speter to be simpler and more consistent. 548538032Speter Delete check for funny qf file names. This didn't really give 548638032Speter any extra security and caused some people some problems. 548738032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 548838032Speter at compile time.) Suggested by Kyle Jones of UUNET. 548938032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 549038032Speter merge with DSN code; this is simpler and more consistent. 549138032Speter This may affect some people who have written their own 549238032Speter checkcompat() routine. 549338032Speter (Internal change.) Eliminate `D' line in qf file. The df file 549438032Speter is now assumed to be the same name as the qf file (with 549538032Speter the `q' changed to a `d', of course). 549638032Speter Avoid forking for delivery if all recipient mailers are marked as 549738032Speter "expensive" -- this can be a major cost on some systems. 549838032Speter Essentially, this forces sendmail into "queue only" mode 549938032Speter if all it is going to do is queue anyway. 550038032Speter Avoid sending a null message in some rather unusual circumstances 550138032Speter (specifically, the RCPT command returns a temporary 550238032Speter failure but the connection is lost before the DATA 550338032Speter command). Fix from Scott Hammond of Secure Computing 550438032Speter Corporation. 550538032Speter Change makesendmail to use a somewhat more rational naming scheme: 550638032Speter Makefiles and obj directories are named $os.$rel.$arch, 550738032Speter where $os is the operating system (e.g., SunOS), $rel is 550838032Speter the release number (e.g., 5.3), and $arch is the machine 550938032Speter architecture (e.g., sun4). Any of these can be omitted, 551038032Speter and anything after the first dot in a release number can 551138032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 551238032Speter version used $os.$arch.$rel and was rather less general. 551338032Speter Change makesendmail to do a "make depend" in the target directory 551438032Speter when it is being created. This involves adding an empty 551538032Speter "depend:" entry in most Makefiles. 551638032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 551738032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 551838032Speter of the Finnish Meteorological Institute. 551938032Speter Fix problem that could cause multiple responses to DATA command 552038032Speter on header syntax errors (e.g., lines beginning with colons). 552138032Speter Problem noted by Jens Thomassen of the University of Oslo. 552238032Speter Don't let null bytes in headers cause truncation of the rest of 552338032Speter the header. 552438032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 552538032Speter Increase timeouts on message data puts to allow time for receivers 552638032Speter to canonify addresses in headers on the fly. This is still 552738032Speter a rather ugly heuristic. From Motonori Nakamura. 552838032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 552938032Speter records are not used when canonifying names, and when MX 553038032Speter lookups are done for addressing they must be fully 553138032Speter qualified. This is useful if you have a wildcard MX record, 553238032Speter although it may cause other problems. In general, don't use 553338032Speter wildcard MX records. Patch from Motonori Nakamura. 553438032Speter Eliminate default two-line SMTP greeting message. Instead of 553538032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 553638032Speter is added between the first and second word of the first 553738032Speter line of the greeting message (i.e., immediately after the 553838032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 553938032Speter compile flag. Old sendmails won't see the ESMTP, but that's 554038032Speter acceptable because SIZE was the only useful extension that 554138032Speter old sendmails understand. 554238032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 554338032Speter invoked state dumps. From Masaharu Onishi. 554438032Speter Allow on-line comments in .forward and :include: files; they are 554538032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 554638032Speter is a space or a tab. This is intended for native 554738032Speter representation of non-ASCII sets such as Japanese, where 554838032Speter existing encodings would be unreadable or would lose 554938032Speter data -- for example, 555038032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 555138032Speter (romanized/less information) 555238032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 555338032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 555438032Speter (with MIME encoding, not human readable) 555538032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 555638032Speter (native encoding with ISO-2022-JP) 555738032Speter The last form is human readable in the Japanese environment. 555838032Speter Based on a fix from (surprise!) Motonori Nakamura. 555938032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 556038032Speter messages to that host; these are most frequently associated 556138032Speter with addresses rather than the host, with the exception of 556238032Speter 421 (service shutting down). The effect was to cause queues 556338032Speter to sometimes take an excessive time to flush. Reported by 556438032Speter Robert Sargent of Southern Geographics Technologies and 556538032Speter Eric Prestemon of American University. 556638032Speter Add Nice=N mailer option to set the niceness at which a mailer will 556738032Speter run. This is actually a relative niceness (that is, an 556838032Speter increment on the background value). 556938032Speter Log queue runs that are skipped due to high loads. They are logged 557038032Speter at LOG_INFO priority iff the log level is > 8. Contributed 557138032Speter by Bruce Nagel of Data General. 557238032Speter Allow the error mailer to accept a DSN-style error status code 557338032Speter instead of an sysexits status code in the host part. 557438032Speter Anything with a dot will be interpreted as a DSN-style code. 557538032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 557638032Speter to encode characters that might be munged by an EBCDIC system 557738032Speter in addition to the set required by RFC 1521. The additional 557838032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 557938032Speter (Think of "IBM 360" as the mnemonic for this flag.) 558038032Speter Change check for mailing to files to look for a pathname of [FILE] 558138032Speter rather than looking for the mailer named *file*. The mapping 558238032Speter of leading slashes still goes to the *file* mailer. This 558338032Speter allows you to implement the *file* mailer as a separate 558438032Speter program, for example, to insert a Content-Length: header 558538032Speter or do special security policy. However, note that the usual 558638032Speter initial checking for the file permissions is still done, and 558738032Speter the program in question needs to be very careful about how 558838032Speter it does the file write to avoid security problems. 558938032Speter Be able to read ~root/.forward even if the path isn't accessible to 559038032Speter regular users. This is disrecommended because sendmail 559138032Speter sometimes does not run as root (e.g., when an unsafe option 559238032Speter is specified on the command line), but should otherwise be 559338032Speter safe because .forward files must be owned by the user for 559438032Speter whom mail is being forwarded, and cannot be a symbolic link. 559538032Speter Suggested by Forrest Aldrich of Wang Laboratories. 559638032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 559738032Speter file. This is used for canonifying hostnames when the 559838032Speter service type is "files". 559938032Speter Implement programs on F (read class from file) line. The syntax is 560038032Speter Fc|/path/to/program to read the output from the program 560138032Speter into class "c". 560238032Speter Probe the network interfaces to find alternate names for this 560338032Speter host. Requires the SIOCGIFCONF ioctl call. Code 560438032Speter contributed by SunSoft. 560538032Speter Add "E" configuration line to set or propagate environment 560638032Speter variables into children. "E<envar>" will propagate 560738032Speter the named variable from the environment when sendmail 560838032Speter was invoked into any children it calls; "E<envar>=<value>" 560938032Speter sets the named variable to the indicated value. Any 561038032Speter variables not explicitly named will not be in the child 561138032Speter environment. However, sendmail still forces an 561238032Speter "AGENT=sendmail" environment variable, in part to enforce 561338032Speter at least one environment variable, since many programs and 561438032Speter libraries die horribly if this is not guaranteed. 561538032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 561638032Speter alias databases -- new algorithm looks for the substring 561738032Speter "/yp/" in the file name. This is more portable and involves 561838032Speter less overhead. Suggested by Motonori Nakamura. 561938032Speter Dynamically allocate the queue work list so that you don't lose 562038032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 562138032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 562238032Speter should not need to be changed) and the MaxQueueRunSize option, 562338032Speter which is the absolute maximum number of jobs that will ever 562438032Speter be handled in a single queue run. Based on code contributed 562538032Speter by Brian Coan of the Institute for Global Communications. 562638032Speter Log message when a message is dropped because it exceeds the maximum 562738032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 562838032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 562938032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 563038032Speter of Mark G. Thomas Consulting. 563138032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 563238032Speter OS-dependent defines). The old semantic of -d0.1 to not 563338032Speter run the daemon in background has been moved to -d99.100, 563438032Speter and the old 52.5 flag (to avoid disconnect() from closing 563538032Speter all output files) has been moved to 52.100. This makes 563638032Speter things more consistent (flags below .100 don't change 563738032Speter semantics) and separates out the backgrounding so that 563838032Speter it doesn't happen automatically on other unrelated debugging 563938032Speter flags. 564038032Speter If -t is used but no addresses are found in the header, give an 564138032Speter error message rather than just doing nothing. Fix from 564238032Speter Motonori Nakamura. 564338032Speter On systems (like SunOS) where the effective gid is not necessarily 564438032Speter included in the group list returned by getgroups(), the 564538032Speter `restrictmailq' option could sometimes cause an authorized 564638032Speter user to not be able to use `mailq'. Fix from Charles Hannum 564738032Speter of MIT. 564838032Speter Allow symbolic service names for [IPC] mailers. Suggested by 564938032Speter Gerry Magennis of Logica International. 565038032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 565138032Speter when running DNS. For example, if the name FTP.Foo.ORG is 565238032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 565338032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 565438032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 565538032Speter This is technically illegal under RFC 822 and 1123, but the 565638032Speter IETF is moving toward legalizing it. Note that turning on 565738032Speter this option is not sufficient to guarantee that a downstream 565838032Speter neighbor won't rewrite the address for you. 565938032Speter Add "-m" flag to makesendmail script -- this tells you what object 566038032Speter directory and Makefile it will use, but doesn't actually do 566138032Speter the make. 566238032Speter Do some additional checking on the contents of the qf file to try 566338032Speter to detect attacks against the qf file. In particular, 566438032Speter abort on any line beginning "From ", and add an "end of 566538032Speter file" line -- any data after that line is prohibited. 566638032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 566738032Speter choices. This can be overridden in the Makefile by using 566838032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 566938032Speter (to the extent that we know it) or by defining 567038032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 567138032Speter sendmail 8 to have more consistent installation instructions. 567238032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 567338032Speter of Sun Microsystems. 567438032Speter Improved symbol table hash function from Eric Wassenaar. This one 567538032Speter is at least 50% faster. 567638032Speter Fix problem that didn't notice that timeout on file open was a 567738032Speter transient error. Fix from Larry Parmelee of Cornell 567838032Speter University. 567938032Speter Allow comments (lines beginning with a `#') in files read for 568038032Speter classes. Suggested by Motonori Nakamura. 568138032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 568238032Speter of dropping out entirely. This makes testing some of the 568338032Speter name server lookups easier to deal with when there are 568438032Speter hung servers. From Motonori Nakamura. 568538032Speter Add new ${opMode} macro that is set to the current operation mode 568638032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 568738032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 568838032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 568938032Speter Kind of like queue-only mode (Odq) except it tries to avoid 569038032Speter any external service requests; for dial-on-demand hosts that 569138032Speter want to minimize DNS lookups when mail is being queued. For 569238032Speter this to work you will also have to make sure that gethostbyname 569338032Speter of your local host name does not do a DNS lookup. 569438032Speter Improved handling of "out of space" conditions from John Myers of 569538032Speter Carnegie Mellon. 569638032Speter Improved security for mailing to files on systems that have fchmod(2) 569738032Speter support. 569838032Speter Improve "cannot send message for N days" message -- now says "could 569938032Speter not send for past N days". Suggested by Tom Moore of AT&T 570038032Speter Global Information Solutions. 570138032Speter Less misleading Subject: line on messages sent to postmaster only. 570238032Speter From Motonori Nakamura. 570338032Speter Avoid duplicate error messages on bad command line flags.

Problem reported by David 571138032Speter James of British Telecom. 571238032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 571338032Speter from Alexander Dupuy of System Management ARTS. 571438032Speter Delete duplicates in MX lists -- believe it or not, there are sites 571538032Speter that list the same host twice in an MX list. This deletion 571638032Speter only works on adjacent preferences, so an MX list that 571738032Speter had A=5, B=10, A=15 would leave both As, but one that had 571838032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 571938032Speter just in case there is something weird I haven't thought of. 572038032Speter Suggested by Barry Shein of Software Tool & Die. 572138032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 581638032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 581738032Speter University of Brno (Czech Republic). 581838032Speter KSR OS 1.2.2 support from Todd Miller of the University 581938032Speter of Colorado. 582038032Speter UX4800 support from Kazuhisa Shimizu of NEC. 582138032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 582238032Speter in type ``btree'' maps. The semantics of this are undefined 582338032Speter for regular maps, but it can be useful for the user database. 582438032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 582538032Speter lookups while the rebuild is going on. There is a race 582638032Speter condition between the open(... O_TRUNC ...) and the lock 582738032Speter on the file, but it should be quite small. 582838032Speter SMRSH: sendmail restricted shell added to the release. This can 582938032Speter be used as an alternative to /bin/sh for the "prog" mailer, 583038032Speter giving the local administrator more control over what 583138032Speter programs can be run from sendmail. 583238032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 583338032Speter part of the release proper, and isn't fully supported; in 583438032Speter particular, it does not run on System V based systems and 583538032Speter never will. 583638032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 583738032Speter to allow rmail to compile on systems that don't have 583838032Speter function prototypes and systems that don't have snprintf. 583938032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 584038032Speter lists by transaction delay times so that addresses that 584138032Speter respond quickly get sent first. This is to prevent very 584238032Speter sluggish servers from delaying other peoples' mail. 584338032Speter Contributed by Tony Sanders of BSDI. 584438032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 584538032Speter of BSDI. This has a lot of comments to help people out. 584638032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 584738032Speter put this on the m4 command line. On GNU m4 (which 584838032Speter supports the __file__ primitive) you can run m4 in an 584938032Speter arbitrary directory -- use either: 585038032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 585138032Speter or 585238032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 585338032Speter On other versions of m4 that don't support __file__, you 585438032Speter can use: 585538032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 585638032Speter (Note the trailing slash on the _CF_DIR_ definition.) 585738032Speter Old versions of m4 will default to _CF_DIR_=.. for back 585838032Speter compatibility. 585938032Speter CONFIG: fix mail from <> so it will properly convert to 586038032Speter MAILER-DAEMON on local addresses. 586138032Speter CONFIG: fix code that was supposed to catch colons in host 586238032Speter names. Problem noted by John Gardiner Myers of CMU. 586338032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 586438032Speter From Paul Riddle of the University of Maryland, Baltimore 586538032Speter County. 586638032Speter CONFIG: Catch and reject "." as a host address. 586738032Speter CONFIG: Generalize domaintable to look up all domains, not 586838032Speter just unqualified ones. 586938032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 587038032Speter was never used and didn't work anyway. 587138032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 587238032Speter and d on all mailers in the UUCP class. 587338032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 587438032Speter look for an alias for "user+detail", then for "user+*", and 587538032Speter finally for "user". This is intended for forwarding mail 587638032Speter for system aliases such as root and postmaster to a 587738032Speter centralized hub. 587838032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 587938032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 588038032Speter The F=8 flag is also set on the "relay" mailer, since 588138032Speter this is expected to be another sendmail. 588238032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 588338032Speter the name of the UUCP_RELAY -- in some cases, this is the 588438032Speter wrong value (e.g., when we have local UUCP connections), 588538032Speter and this can create unreplyable addresses. From Chip 588638032Speter Rosenthal of Unicom. 588738032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 588864562Sgshapiro Received: header inserted into all messages. Suggested by 588938032Speter Gary Mills of the University of Manitoba. 589038032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 589143730Speter to get the old behavior. I did this upon observing 589238032Speter that almost everyone needed this feature, and that the 589338032Speter concept I was trying to make happen didn't work with 589438032Speter some user agents anyway. FEATURE(notsticky) still works, 589538032Speter but it is a no-op. 589638032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 589738032Speter names are sent, rather than immediately diagnosing them 589838032Speter as User Unknown. 589938032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 590038032Speter and RELAY_MAILER_ARGS to set the arguments for the 590138032Speter indicated mailers. All default to "IPC $h". Patch from 590238032Speter Larry Parmelee of Cornell University. 590338032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 590438032Speter on the client side" and F=P to get an appropriate 590538032Speter return-path. From Kimmo Suominen. 590638032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 590738032Speter as the local mailer. For addresses of the form "user+detail" 590838032Speter the "detail" part is passed to procmail via the -a flag. 590938032Speter Contributed by Kimmo Suominen. 591038032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 591138032Speter use from mailertables. This lets you execute arbitrary 591238032Speter procmail scripts. Contributed by Kimmo Suominen. 591338032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 591438032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 591538032Speter Paul Southworth of CICNet Systems Support. 591638032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 591738032Speter This causes the null return path to be rewritten as 591838032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 591938032Speter From Michael Hohmuth of Technische Universitat Dresden. 592038032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 592138032Speter list us as the best possible MX record to be treated as 592238032Speter though they were local (essentially, assume that they 592338032Speter are included in $=w). This can cause additional DNS 592438032Speter traffic, but is easier to administer if this fits your 592538032Speter local model. It does not work reliably if there are 592638032Speter multiple hosts that share the best MX preference. 592738032Speter Code contributed by John Oleynick of Rutgers. 592838032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 592938032Speter SHell) instead of /bin/sh as the program used for delivery 593038032Speter to programs. If an argument is included, it is used as 593138032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 593238032Speter assumed. 593338032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 593438032Speter size of messages to the local and procmail mailers 593538032Speter respectively. Contributed by Brad Knowles of the Defense 593638032Speter Information Systems Agency. 593738032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 593838032Speter (just like text outside of angle brackets) in order to 593938032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 594038032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 594138032Speter any real systems any more) and tweak the DOMAIN macro 594238032Speter so that it is less likely that users will accidentally use 594338032Speter the Berkeley defaults. Also, create some generic files 594438032Speter that really can be used in the real world. 594538032Speter CONFIG: Add new configuration macros to set character sets for 594638032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 594738032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 594838032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 594938032Speter The old name will still be accepted for a while at least. 595038032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 595138032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 595238032Speter As with all relays, it can be ``mailer:hostname''. Suggested 595338032Speter by Scott Hutton. 595438032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 595538032Speter by Barb Dijker of Labyrinth Computer Services. 595638032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 595738032Speter performance for large alias files, and this confused many 595838032Speter people. 595938032Speter CONFIG: Add confCF_VERSION to append local information to the 596038032Speter configuration version number displayed during SMTP startup. 596138032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 596238032Speter would only work when locally addressed. Fix from 596338032Speter Edvard Tuinder of Cistron Internet Services. 596438032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 596543730Speter "n" (CheckAliases) is set when rebuilding alias database. 596638032Speter Based on code contributed by Claude Marinier. 596738032Speter CONFIG: Allow mailertable to have values of the form 596838032Speter ``error:code message''. The ``code'' is a status code 596938032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 597038032Speter Contributed by David James <dwj@agw.bt.co.uk>. 597138032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 597238032Speter sender domains that will be replaced with the masquerade name. 597338032Speter These domains will not be treated as local, but if mail passes 597438032Speter through with sender addresses in those domains they will be 597538032Speter replaced by the masquerade name. These can also be specified 597638032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 597738032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 597838032Speter as well as the header. Substantial improvements to this 597938032Speter code were contributed by Per Hedeland. 598038032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 598138032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 598238032Speter by Kimmo Suominen. 598338032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 598438032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 598538032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 598638032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 598738032Speter UUCP addressing.

This caused UnixWare 613038032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 613138032Speter Novell Labs Europe. 613238032Speter Fix problem with static linking of local getopt routine when 613338032Speter using GNU's ld command. Fix from John Kennedy of 613438032Speter Cal State Chico. 613538032Speter It was possible to turn off privacy flags. Problem noted by 613638032Speter *Hobbit*. 613738032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 613838032Speter and Liudvikas Bukys. 613938032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 614038032Speter from Spider Boardman. 614138032Speter CONFIG: No changes (version number only, to keep it in sync 614238032Speter with the binaries). 614338032Speter 614464562Sgshapiro8.6.10/8.6.10 1995/02/10 614538032Speter SECURITY: Diagnose bogus values to some command line flags that 614638032Speter could allow trash to get into headers and qf files. 614738032Speter Validate the name of the user returned by the IDENT protocol. 614838032Speter Some systems that really dislike IDENT send intentionally 614938032Speter bogus information. Problem pointed out by Michael Bushnell 615038032Speter of the Free Software Foundation. Has some security 615138032Speter implications. 615238032Speter Fix a problem causing error messages about DNS problems when 615338032Speter the host name contained a percent sign to act oddly 615438032Speter because it was passed as a printf-style format string. 615538032Speter In some cases this could cause core dumps. 615638032Speter Avoid possible buffer overrun in returntosender() if error 615738032Speter message is quite long. From Fletcher Mattox of the 615838032Speter University of Texas. 615938032Speter Fix a problem that would silently drop "too many hops" error 616038032Speter messages if and only if you were sending to an alias. 616138032Speter From Jon Giltner of the University of Colorado and 616238032Speter Dan Harton of Oak Ridge National Laboratory. 616338032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 616438032Speter set and e->e_message was null. Fix from Bruce Nagel of 616538032Speter Data General. 616638032Speter Fix problem that can still cause df files to be left around 616738032Speter after "hop count exceeded" messages. Fix from Andrew 616838032Speter Chang and Shau-Ping Lo of SunSoft. 616938032Speter Fix a problem that can cause buffer overflows on very long 617038032Speter user names (as might occur if you piped to a program 617138032Speter with a lot of arguments). 617238032Speter Avoid returning an error and re-queueing if the host signature 617338032Speter is null; this can occur on addresses like ``user@.''. 617438032Speter Problem noted by Wesley Craig and the University of 617538032Speter Michigan. 617638032Speter Avoid possible calls to malloc(0) if MCI caching is turned 617738032Speter off. Bug fix from Pierre David of the Laboratoire 617838032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 617938032Speter Universite de Versailles - St Quentin, and Jacky 618038032Speter Thibault. 618138032Speter Make a local copy of the line being sent via senttolist() -- in 618238032Speter some cases, buffers could get trashed by map lookups 618338032Speter causing it to do unexpected things. This also simplifies 618438032Speter some of the map code. 618538032Speter CONFIG: No changes (version number only, to keep it in sync 618638032Speter with the binaries). 618738032Speter 618864562Sgshapiro8.6.9/8.6.9 1994/04/19 618938032Speter Do all mail delivery completely disconnected from any terminal. 619038032Speter This provides consistency with daemon delivery and 619138032Speter may have some security implications. 619238032Speter Make sure that malloc doesn't get called with zero size, 619338032Speter since that fails on some systems. Reported by Ed 619438032Speter Hill of the University of Iowa. 619538032Speter Fix multi-line values for $e (SMTP greeting message). Reported 619638032Speter by Mike O'Connor of Ford Motor Company. 619738032Speter Avoid syserr if no NIS domain name is defined, but the map it 619838032Speter is trying to open is optional. From Win Bent of USC. 619938032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 620038032Speter Hesiod support for UDB from Todd Miller of the University of 620138032Speter Colorado. Use "hesiod" as the service name in the U 620238032Speter option. 620338032Speter Fix a problem that failed to set the "authentic" host name (that 620438032Speter is, the one derived from the socket info) if you called 620538032Speter sendmail -bs from inetd. Based on code contributed by 620638032Speter Todd Miller (this problem was also reported by Guy Helmer 620738032Speter of Dakota State University). This also fixes a related 620838032Speter problem reported by Liudvikas Bukys of the University of 620938032Speter Rochester. 621038032Speter Parameterize "nroff -h" in all the Makefiles so people with 621138032Speter variant versions can use them easily. Suggested by 621238032Speter Peter Collinson of Hillside Systems. 621338032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 621438032Speter spaces between parameters instead of one. Reported by 621538032Speter Valdis Kletnieks of Virginia Tech. 621638032Speter Reduce the number of system calls during message collection by 621738032Speter using global timeouts around the collect() loop. This 621838032Speter code was contributed by Eric Wassenaar. 621938032Speter If the initial hostname name gathering results in a name 622038032Speter without a dot (usually caused by NIS misconfiguration) 622138032Speter and BIND is compiled in, directly access DNS to get 622238032Speter the canonical name. This should make life easier for 622338032Speter Solaris systems. If it still can't be resolved, and 622438032Speter if the name server is listed as "required", try again 622538032Speter in 30 seconds. If that also fails, exit immediately to 622638032Speter avoid bogus "config error: mail loops back to myself" 622738032Speter messages. 622838032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 622938032Speter message to explain how much space was available and 623038032Speter sound a bit less threatening. Suggested by Stan Janet 623138032Speter of the National Institute of Standards and Technology. 623238032Speter If mail is delivered to an alias that has an owner, deliver any 623338032Speter requested return-receipt immediately, and strip the 623438032Speter Return-Receipt-To: header from the subsequent message. 623538032Speter This prevents a certain class of denial of service 623638032Speter attack, arguably gives more reasonable semantics, and 623738032Speter moves things more towards what will probably become a 623838032Speter network standard. Suggested by Christopher Davis of 623938032Speter Kapor Enterprises. 624038032Speter Add a "noreceipts" privacy flag to turn off all return receipts 624138032Speter without recompiling. 624238032Speter Avoid printing ESMTP parameters as part of the error message 624338032Speter if there are errors during parsing. This change is 624438032Speter purely cosmetic. 624538032Speter Avoid sending out error messages during the collect phase of 624638032Speter SMTP; there is an MVS mailer from UCLA that gets 624738032Speter confused by this. Of course, I think it's their bug.... 624838032Speter Check for the $j macro getting undefined, losing a dot, or getting 624938032Speter lost from $=w in the daemon before accepting a connection; 625038032Speter if it is, it dumps state, prints a LOG_ALERT message, 625138032Speter and drops core for debugging. This is an attempt to 625238032Speter track down a bug that I thought was long since gone. 625338032Speter If you see this, please forward the log fragment to 625438032Speter sendmail@sendmail.ORG. 625538032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 625638032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 625738032Speter Wolfhugel. 625838032Speter Instead of trying to truncate the listen queue for the server 625938032Speter SMTP port when the load average is too high, just close 626038032Speter the port completely and reopen it later as needed. 626138032Speter This ensures that the other end gets a quick "connection 626238032Speter refused" response, and that the connection can be 626338032Speter recovered later. In particular, some socket emulations 626438032Speter seem to get confused if you tweak the listen queue 626538032Speter size around and can never start listening to connections 626638032Speter again. The down side is that someone could start up 626738032Speter another daemon process in the interim, so you could 626838032Speter have multiple daemons all not listening to connections; 626938032Speter this could in turn cause the sendmail.pid file to be 627038032Speter incorrect. A better approach might be to accept the 627138032Speter connection and give a 421 code, but that could break 627243730Speter other mailers in mysterious ways and have paging behavior 627338032Speter implications. 627438032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 627538032Speter set debugging on the wrong socket. From Eric Wassenaar. 627638032Speter When creating a df* temporary file, be sure you truncate any 627738032Speter existing data in the file -- otherwise system crashes 627838032Speter and the like could result in extra data being sent. 627938032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 628038032Speter doc directory. This includes some additional 628138032Speter information. 628238032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 628338032Speter of recipient envelope addresses. This should have been 628438032Speter handled by the $&h trick, but broke if people were 628538032Speter mixing domainized and UUCP addresses. They should 628638032Speter probably have converted all the way over to uucp-uudom 628738032Speter instead of uucp-{new,old}, but the failure mode was to 628838032Speter loop the mail, which was bad news. 628938032Speter Portability fixes: 629038032Speter Newer BSDI systems (several people). 629138032Speter Older BSDI systems from Christophe Wolfhugel. 629238032Speter Intergraph CLIX, from Paul Southworth of CICNet. 629338032Speter UnixWare, from Evan Champion. 629438032Speter NetBSD from Adam Glass. 629538032Speter Solaris from Quentin Campbell of the University of 629638032Speter Newcastle upon Tyne. 629738032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 629838032Speter Corporation. 629938032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 630038032Speter SunOS (it has setsid() and setvbuf() calls) from 630138032Speter Jonathan Kamens of OpenVision Technologies. 630238032Speter HP-UX from Tor Lillqvist. 630338032Speter New Files: 630438032Speter src/Makefile.CLIX 630538032Speter src/Makefile.NCR3000 630638032Speter doc/changes/Makefile 630738032Speter doc/changes/changes.me 630838032Speter doc/changes/changes.ps 630938032Speter 631064562Sgshapiro8.6.8/8.6.6 1994/03/21 631138032Speter SECURITY: it was possible to read any file as root using the 631238032Speter E (error message) option. Reported by Richard Jones; 631338032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 631438032Speter 631564562Sgshapiro8.6.7/8.6.6 1994/03/14 631638032Speter SECURITY: it was possible to get root access by using weird 631738032Speter values to the -d flag. Thanks to Alain Durand of 631838032Speter INRIA for forwarding me the notice from the bugtraq 631938032Speter list. 632038032Speter 632164562Sgshapiro8.6.6/8.6.6 1994/03/13 632238032Speter SECURITY: the ability to give files away on System V-based 632338032Speter systems proved dangerous -- don't run as the owner 632438032Speter of a :include: file on a system that allows giveaways. 632538032Speter Unfortunately, this also applies to determining a 632638032Speter valid shell. 632738032Speter IMPORTANT: Previous versions weren't expiring old connections 632838032Speter in the connection cache for a long time under some 632938032Speter circumstances. This could result in resource exhaustion, 633038032Speter both at your end and at the other end. This checks the 633138032Speter connections for timeouts much more frequently. From 633238032Speter Doug Anderson of NCSC. 633338032Speter Fix a glitch that snuck in that caused programs to be run as 633438032Speter the sender instead of the recipient if the mail was 633538032Speter from a local user to another local user. From 633638032Speter Motonori Nakamura of Kyoto University. 633738032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 633838032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 633938032Speter Bryan Costales of ICSI. 634038032Speter Change the method used to declare the "statfs" availability; 634138032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 634238032Speter tweaking in conf.c, there is a single #define called 634338032Speter SFS_TYPE which takes on one of six values (SFS_NONE 634438032Speter for no statfs availability, SFS_USTAT for the ustat(2) 634538032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 634638032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 634738032Speter statfs(2) call with the declarations in <sys/vfs.h>, 634838032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 634938032Speter Fix glitch in NetInfo support that could return garbage if 635038032Speter there was no "/locations/sendmail" property. From 635138032Speter David Meyer of the University of Virginia. 635238032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 635338032Speter to allow Linux to turn it off even though it is a 635438032Speter BSD-like system. 635538032Speter Allow setting of "ident" timeout to zero to turn off the ident 635638032Speter protocol entirely. 635738032Speter Make 7-bit stripping local to a connection (instead of to a 635838032Speter mailer); this allows you to specify that SMTP is a 635938032Speter 7-bit channel, but revert to 8-bit should it advertise 636038032Speter that it supports 8BITMIME. You still have to specify 636138032Speter mailer flag 7 to get this stripping at all. 636238032Speter Improve makesendmail script so it handles more cases automatically. 636338032Speter Tighten up restrictions on taking ownership of :include: files 636438032Speter to avoid problems on systems that allow you to give away 636538032Speter files. 636638032Speter Fix a problem that made it impossible to rebuild the alias 636738032Speter file if it was on a read-only file system. From 636838032Speter Harry Edmon of the University of Washington. 636938032Speter Improve MX randomization function. From John Gardiner Myers 637038032Speter of CMU. 637138032Speter Fix a minor glitch causing a bogus message to be printed (used 637238032Speter %s instead of %d in a printf string for the line number) 637338032Speter when a bad queue file was read. From Harry Edmon. 637438032Speter Allow $s to remain NULL on locally generated mail. I'm not 637538032Speter sure this is necessary, but a lot of people have complained 637638032Speter about it, and there is a legitimate question as to whether 637738032Speter "localhost" is legal as an 822-style domain. 637838032Speter Fix a problem with very short line lengths (mailer L= flag) in 637938032Speter headers. This causes a leading space to be added onto 638038032Speter continuation lines (including in the body!), and also 638138032Speter tries to wrap headers containing addresses (From:, To:, 638238032Speter etc) intelligently at the shorter line lengths. Problem 638338032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 638438032Speter Log the real user name when logging syserrs, since these can have 638538032Speter security implications. Suggested by several people. 638638032Speter Fix address logging of cached connections -- it used to always 638738032Speter log the numeric address as zero. This is a somewhat 638838032Speter bogus implementation in that it does an extra system 638938032Speter call, but it should be an inexpensive one. Fix from 639038032Speter Motonori Nakamura. 639138032Speter Tighten up handling of short syslog buffers even more -- there 639238032Speter were cases where the outgoing relay= name was too long 639338032Speter to share a line with delay= and mailer= logging. 639438032Speter Limit the overhead on split envelopes to one open file descriptor 639538032Speter per envelope -- previously the overhead was three 639638032Speter descriptors. This was in response to a problem reported 639738032Speter by P{r (Pell) Emanuelsson. 639838032Speter Fixes to better handle the case of unexpected connection closes; 639938032Speter this redirects the output to the transcript so the info 640038032Speter is not lost. From Eric Wassenaar. 640138032Speter Fix potential string overrun if you macro evaluate a string that 640238032Speter has a naked $ at the end. Problem noted by James Matheson 640338032Speter <jmrm@eng.cam.ac.uk>. 640438032Speter Make default error number on $#error messages 553 (``Requested 640538032Speter action not taken: mailbox name not allowed'') instead of 640638032Speter 501 (``Syntax error in parameters or arguments'') to 640738032Speter avoid bogus "protocol error" messages. 640838032Speter Strip off any existing trailing dot on names during $[ ... $] 640938032Speter lookup. This prevents it from ending up with two dots 641038032Speter on the end of dot terminated names. From Wesley Craig 641138032Speter of the University of Michigan and Bryan Costales of ICSI. 641238032Speter Clean up file class reading so that the debugging information is 641338032Speter more informative. It hadn't been using setclass, so you 641438032Speter didn't see the class items being added. 641538032Speter Avoid core dump if you are running a version of sendmail where 641638032Speter NIS is compiled in, and you specify an NIS map, but 641738032Speter NIS is not running. Fix from John Oleynick of 641838032Speter Rutgers. 641938032Speter Diagnose bizarre case where res_search returns a failure value, 642038032Speter but sets h_errno to a success value. 642138032Speter Make sure that "too many hops" messages are considered important 642238032Speter enough to send an error to the Postmaster (that is, the 642338032Speter address specified in the P option). This fix should 642438032Speter help problems that cause the df file to be left around 642538032Speter sometimes -- unfortunately, I can't seem to reproduce 642638032Speter the problem myself. 642738032Speter Avoid core dump (null pointer reference) on EXPN command; this 642838032Speter only occurred if your log level was set to 10 or higher 642938032Speter and the target account was an alias or had a .forward file. 643038032Speter Problem noted by Janne Himanka. 643138032Speter Avoid "denial of service" attacks by someone who is flooding your 643238032Speter SMTP port with bad commands by shutting the connection 643338032Speter after 25 bad commands are issued. From Kyle Jones of 643438032Speter UUNET. 643538032Speter Fix core dump on error messages with very long "to" buffers; 643638032Speter fmtmsg overflows the message buffer. Fixed by trimming 643738032Speter the to address to 203 characters. Problem reported by 643838032Speter John Oleynick. 643938032Speter Fix configuration for HASFLOCK -- there were some spots where 644038032Speter a #ifndef was incorrectly #ifdef. Pointed out by 644138032Speter George Baltz of the University of Maryland. 644238032Speter Fix a typo in savemail() that could cause the error message To: 644338032Speter lists to be incorrect in some places. From Motonori 644438032Speter Nakamura. 644538032Speter Fix a glitch that can cause duplicate error messages on split 644638032Speter envelopes where an address on one of the lists has a 644738032Speter name server failure. Fix from Voradesh Yenbut of the 644838032Speter University of Washington. 644938032Speter Fix possible bogus pointer reference on ESMTP parameters that 645038032Speter don't have an ``=value'' part. 645138032Speter CNAME loops caused an error message to be generated, but also 645238032Speter re-queued the message. Changed to just re-queue the 645338032Speter message (it's really hard to just bounce it because 645438032Speter of the weird way the name server works in the presence 645538032Speter of CNAME loops). Problem noted by James M.R.Matheson 645638032Speter of Cambridge University. 645738032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 645838032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 645938032Speter user name. Suggested by Andreas Stolcke of ICSI. 646038032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 646138032Speter override it easily in the Makefile -- that is, you can 646238032Speter turn it off using -DNAMED_BIND=0. 646338032Speter If a gethostbyname(...) of an address with a trailing dot fails, 646438032Speter try it without the trailing dot. This is because if 646538032Speter you have a version of gethostbyname() that falls back 646638032Speter to NIS or the /etc/hosts file it will fail to find 646738032Speter perfectly reasonable names that just don't happen to 646838032Speter be dot terminated in the hosts file. You don't want to 646938032Speter strip the dot first though because we're trying to ensure 647038032Speter that country names that match one of your subdomains get 647138032Speter a chance. 647238032Speter PRALIASES: fix bogus output on non-null-terminated strings. 647338032Speter From Bill Gianopoulos of Raytheon. 647438032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 647538032Speter This was in code intended to only catch the self-literal 647638032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 647738032Speter IP address), but the code was broken. However, it will 647838032Speter still do this if $M is defined; this is necessary to 647938032Speter get client configurations to work (sigh). Note that this 648038032Speter means that $M overrides :mailname entries in the user 648138032Speter database! Problem noted by Paul Southworth. 648238032Speter CONFIG: Fix definition of Solaris help file location. From 648338032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 648438032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 648538032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 648638032Speter and USENET_MAILER_MAX to tweak the maximum message 648738032Speter size for various mailers. 648838032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 648938032Speter instead of assuming that it is "inews" for consistency 649038032Speter with other mailers. From Michael Corrigan of UC San Diego. 649138032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 649238032Speter qualify the address in the SMTP envelope as user@{relay|hub} 649338032Speter instead of user@$j. From Bill Wisner of The Well. 649438032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 649538032Speter CONFIG: Don't turn off case mapping of user names in the local 649638032Speter mailer for IRIX. This was different than most every other 649738032Speter system. 649838032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 649938032Speter envelope. Noted by Thierry Besancon 650038032Speter <besancon@excalibur.ens.fr>. 650138032Speter CONFIG: Don't include -z by default on uux line -- most systems 650238032Speter don't want it set by default. Pointed out by Philippe 650338032Speter Michel of Thomson CSF. 650438032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 650538032Speter host name was foo.bar.ray.com and you matched against 650638032Speter ".ray.com", the old implementation bound %1 to "bar" 650738032Speter instead of "foo.bar". Also, allow "." in the mailertable 650838032Speter to match anything -- essentially, take over SMART_HOST. 650938032Speter This also moves matching of explicit local host names 651038032Speter before the mailertable so they don't have to be special 651138032Speter cased in the mailertable data. Reported by Bill 651238032Speter Gianopoulos of Raytheon; the fix for the %1 binding 651338032Speter problem was contributed by Nicholas Comanos of the 651438032Speter University of Sydney. 651538032Speter CONFIG: Don't include "root" in class $=L (users to deliver 651638032Speter locally, even if a hub or relay exists) by default. 651738032Speter This is because of the known bug where definition of 651838032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 651938032Speter both and deliver into the local mailbox. 652038032Speter CONFIG: Move up bitdomain and uudomain handling so that they 652138032Speter are done before .UUCP class matching; uudomain was 652238032Speter reported as ineffective before. This also frees up 652338032Speter diversion 8 for future use. Problem reported by Kimmo 652438032Speter Suominen. 652538032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 652638032Speter into host names. As pointed out by Jonathan Kamens, 652738032Speter these are often used because either the forward or reverse 652838032Speter mapping is broken; this translation makes it broken again. 652938032Speter DOC: Clarify $@ and $: in the Install & Op Guide.

From 655638032Speter Bob Campbell at U.C. Berkeley. 655738032Speter Security fix: group ids were not completely set when programs 655838032Speter were invoked. This caused programs to have group 655938032Speter permissions they should not have had (usually group 656038032Speter daemon instead of their own group). In particular, 656138032Speter Perl scripts would refuse to run. 656238032Speter Security: check to make sure files that are written are not 656338032Speter symbolic links (at least under some circumstances). 656438032Speter Although this does not respond to a specific known 656538032Speter attack, it's just a good idea. Suggested by 656638032Speter Christian Wettergren. 656738032Speter Security fix: if a user had an NFS mounted home directory on 656838032Speter a system with a restricted shell listed in their 656938032Speter /etc/passwd entry, they could still execute any 657038032Speter program by putting that in their .forward file. 657138032Speter This fix prevents that by insisting that their shell 657238032Speter appear in /etc/shells before allowing a .forward to 657338032Speter execute a program or write a file. You can disable 657438032Speter this by putting "*" in /etc/shells. It also won't 657538032Speter permit world-writable :include: files to reference 657638032Speter programs or files (there's no way to disable this). 657743730Speter These behaviors are only one level deep -- for 657838032Speter example, it is legal for a world-writable :include: 657938032Speter file to reference an alias that writes a file, on 658038032Speter the assumption that the alias file is well controlled. 658138032Speter Security fix: root was not treated suspiciously enough when 658238032Speter looking into subdirectories. This would potentially 658338032Speter allow a cracker to examine files that were publicly 658438032Speter readable but in a non-publicly searchable directory. 658538032Speter Fix a problem that causes an error on QUIT on a cached 658638032Speter connection to create problems on the current job. 658738032Speter These are typically unrelated, so errors occur in 658838032Speter the wrong place. 658938032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 659038032Speter runs more responsive to load average, and fixes a 659138032Speter problem that ignored the load average in locally 659238032Speter generated mail. From Eric Wassenaar. 659338032Speter Fix possible core dump on aliases with null LHS. From 659438032Speter John Orthoefer of BB&N. 659538032Speter Revert to using flock() whenever possible -- there are just 659638032Speter too many bugs in fcntl() locking, particularly over 659738032Speter NFS, that cause sendmail to fail in perverse ways. 659838032Speter Fix a bug that causes the connection cache to get confused 659938032Speter when sending error messages. This resulted in 660038032Speter "unexpected close" messages. It should fix itself 660138032Speter on the following queue run. Problem noted by 660238032Speter Liudvikas Bukys of the University of Rochester. 660338032Speter Include $k in $=k as documented in the Install & Op Guide. 660438032Speter This seems odd, but it was documented.... From 660538032Speter Michael Corrigan of UCSD. 660638032Speter Fix problem that caused :include:s from alias files to be 660738032Speter forced to be owned by root instead of daemon 660838032Speter (actually DefUid). From Tim Irvin. 660938032Speter Diagnose unrecognized I option values -- from Mortin Forssen 661038032Speter of the Chalmers University of Technology. 661138032Speter Make "error" mailer work consistently when there is no error 661238032Speter code associated with it -- previously it returned OK 661338032Speter even though there was a real problem. Now it assumes 661438032Speter EX_UNAVAILABLE. 661538032Speter Fix bug that caused the last header line of messages that had 661638032Speter no body and which were terminated with EOF instead of 661738032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 661838032Speter Fix core dump on SMTP mail to programs that failed -- it tried 661938032Speter to go to a "next MX host" when none existed, causing 662038032Speter a core dump. From der Mouse at McGill University. 662138032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 662238032Speter this makes it easier to turn it off (using 662338032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 662438032Speter Fix YP_MASTER_NAME store to use the unupdated result of 662538032Speter gethostname() (instead of myhostname(), which tries 662638032Speter to fully qualify the name) to be consistent with 662738032Speter SunOS. If your hostname is unqualified, this fixes 662838032Speter transfers to slave servers. Bug noted by Keith 662938032Speter McMillan of Ameritech Services, Inc. 663038032Speter Fix Ultrix problem: gethostbyname() can return a very large 663138032Speter (> 500) h_length field, which causes the sockaddr 663238032Speter to be trashed. Use the size of the sockaddr instead. 663338032Speter Fix from Bob Manson of Ohio State. 663438032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 663538032Speter defined -- this confuses gethostbyname on hosts 663638032Speter file lookups, which doesn't understand the trailing 663738032Speter dot convention. 663838032Speter Log SMTP server subprocesses that die with a signal instead 663938032Speter of from a clean exit. 664038032Speter If you don't have option "I" set, don't assume that a DNS 664138032Speter "host unknown" message is authoritative -- it 664238032Speter might still be found in /etc/hosts. 664338032Speter Fix a problem that would cause Deferred: messages to be sent 664438032Speter as the subject of an error message, even though the 664538032Speter actual cause of a message was more severe than that. 664638032Speter Problem noted by Chris Seabrook of OSSI. 664738032Speter Fix race condition in DBM alias file locking. From Kyle 664838032Speter Jones of UUNET. 664938032Speter Limit delivery syslog line length to avoid bugs in some 665038032Speter versions of syslog(3). This adds a new compile time 665138032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 665238032Speter University, which is in turn derived from IDA. 665338032Speter Fix quotes inside of comments in addresses -- previously 665438032Speter it insisted that they be balanced, but the 822 spec 665538032Speter says that they should be ignored. 665638032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 665738032Speter debugging). This also evaluates ruleset 89, if set 665838032Speter (with the null input), and logs the result. This 665938032Speter should be used sparingly, since the rewrite process 666038032Speter is not reentrant. 666138032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 666238032Speter documented in the Bat Book. 666338032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 666438032Speter return an error message and did not requeue the message. 666538032Speter Fix based on code from Roland Dirlewanger of 666638032Speter Reseau Regional Aquarel, Bordeaux, France. 666738032Speter Fix a problem that caused a seg fault if you got a 421 error 666838032Speter code during some parts of connection initialization. 666938032Speter I've only seen this when talking to buggy mailers on 667038032Speter the other end, but it shouldn't give a seg fault in 667138032Speter any case. From Amir Plivatsky. 667238032Speter Fix core dump caused by a ruleset call that returns null. 667338032Speter Fix from Bryan Costales of ICSI. 667438032Speter Full-Name: field was being ignored.

Suggested by 668138032Speter Bryan Costales. 668238032Speter Initialize non-alias maps during alias rebuilds -- they may be 668338032Speter needed for parsing. Problem noted by Douglas Anderson. 668438032Speter Log sender address even if no message was collected in SMTP 668538032Speter (e.g., if all RCPTs failed). Suggested by Motonori 668638032Speter Nakamura. 668738032Speter Don't reflect the owner-list contents into the envelope sender 668838032Speter address if the value contains ", :, /, or | (to avoid 668938032Speter illegal addresses appearing there). 669038032Speter Efficiency hack for toktype macro -- from Craig Partridge of 669138032Speter BB&N. 669238032Speter Clean up DNS error printing so that a host name is always 669338032Speter included. 669438032Speter Remember to set $i during queue runs. Reported by Stephen 669538032Speter Campbell of Dartmouth University. 669638032Speter If the environment variable HOSTALIASES is set, use it during 669738032Speter canonification as the name of a file with per-user host 669838032Speter translations so that headers are properly mapped.

From Vince 670838032Speter DeMarco. 670938032Speter Fix a glitch that sometimes caused :include:s that pointed to 671038032Speter NFS filesystems that were down to give an "aliasing/ 671138032Speter forwarding loop broken" message instead of queueing 671238032Speter the message for retry. Noted by William C Fenner of 671338032Speter the NRL Connection Machine Facility. 671438032Speter Fix a problem that could cause a core dump if the input sequence 671538032Speter had (or somehow acquired) a \231 character. 671638032Speter Make sure that route-addrs always have <angle brackets> around 671738032Speter them in non-SMTP envelopes (SMTP envelopes already do 671838032Speter this properly). 671938032Speter Avoid weird headers on unbalanced punctuation of the form: 672038032Speter ``Joe User <user)'' -- this caused reference to the 672138032Speter null macro. Fix from Rick McCarty of IO.COM. 672238032Speter Fix a problem that caused an alias "user: user@local.host" to 672338032Speter not have the QNOTREMOTE bit set; this caused configs 672438032Speter to act as if FEATURE(notsticky) was defined even when 672538032Speter it was not. The effect of the problem was to make it 672638032Speter very hard to to set up satellite sites that had a few 672738032Speter local accounts, with everything else forwarded to a 672838032Speter corporate hub. Reported by Detlef Drewanz of the 672938032Speter University of Rostock and Mark Frost of NCD. 673038032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 673138032Speter addresses. This is more efficient (fewer name server 673238032Speter calls) and fixes certain unusual configurations, such 673338032Speter as those that have ruleset 4 do something that is 673438032Speter non-idempotent unless a mailer-specific ruleset did 673538032Speter something else. Problem reported by Brian J. Coan 673638032Speter of the Institute for Global Communications. 673738032Speter Fix the "obsolete argument" routine in main to better understand 673838032Speter new arguments.

Briefly, if you are sending to host 680438032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 680538032Speter "foo!baz" remains "foo!baz", and anything else has 680638032Speter the local name prepended. 680738032Speter CONFIG: portability fixes for HP-UX. 680838032Speter DOC: several minor problems fixed in the Install & Op Guide. 680938032Speter MAKEMAP: fix core dump problem on lines that are too long or 681038032Speter which lack newline. From Mark Delany. 681138032Speter MAILSTATS: print sums of columns (total messages & kbytes 681238032Speter in and out of the system). From Tom Ferrin of UC 681338032Speter San Francisco Computer Graphics Lab. 681438032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 681538032Speter On HP-UX, /etc/sendmail.cf has been moved to 681638032Speter /usr/lib/sendmail.cf to match HP sendmail. 681738032Speter Permissions have been tightened up on world-writable 681838032Speter :include: files and accounts that have shells 681938032Speter that are not listed in /etc/shells. This may 682038032Speter cause some .forward files that have worked 682138032Speter before to start failing. 682238032Speter SIGUSR1 dumps some state to the log. 682338032Speter NEW FILES: 682438032Speter src/Makefile.DGUX 682538032Speter src/Makefile.Dynix 682638032Speter src/Makefile.FreeBSD 682738032Speter src/Makefile.Mach386 682838032Speter src/Makefile.NetBSD 682938032Speter src/Makefile.RISCos 683038032Speter src/Makefile.SCO 683138032Speter src/Makefile.SVR4 683238032Speter src/Makefile.Titan 683338032Speter cf/mailer/pop.m4 683438032Speter cf/ostype/bsdi1.0.m4 683538032Speter cf/ostype/dgux.m4 683638032Speter cf/ostype/dynix3.2.m4 683738032Speter cf/ostype/sco3.2.m4 683838032Speter makemap/Makefile.dist 683938032Speter praliases/Makefile.dist 684038032Speter 684164562Sgshapiro8.6.4/8.6.4 1993/10/31 684238032Speter Repair core-dump problem (write to read-only memory segment) 684338032Speter if you fall back to the return-to-Postmaster case in 684438032Speter savemail. Problem reported by Richard Liu. 684538032Speter Immediately diagnose bogus sender addresses in SMTP. This 684638032Speter makes quite certain that crackers can't use this 684738032Speter class of attack. 684838032Speter Reliability Fix: check return value from fclose() and fsync() 684938032Speter in a few critical places. 685038032Speter Minor problem in initsys() that reversed a condition for 685138032Speter redirecting the output channel on queue runs. It's 685238032Speter not clear this code even does anything. From Eric 685338032Speter Wassenaar of the Dutch National Institute for Nuclear 685438032Speter and High-Energy Physics. 685538032Speter Fix some problems that caused queue runs to do "too much work", 685638032Speter such as double-reading the Errors-To: header. From 685738032Speter Eric Wassenaar. 685838032Speter Error messages on writing the temporary file (including the 685938032Speter data file) were getting suppressed in SMTP -- this 686038032Speter fix causes them to be properly reported. From Eric 686138032Speter Wassenaar. 686238032Speter Some changes to support AF_UNIX sockets -- this will only 686338032Speter really become relevant in the next release, but some 686438032Speter people need it for local patches. From Michael 686538032Speter Corrigan of UC San Diego. 686638032Speter Use dynamically allocated memory (instead of static buffers) 686738032Speter for macros defined in initsys() and settime(); since 686838032Speter these can have different values depending on which 686938032Speter envelope they are in. From Eric Wassenaar. 687038032Speter Improve logging to show ctladdr on to= logging; this tells you 687138032Speter what uid/gid processes ran as. 687238032Speter Fix a problem that caused error messages to be discarded if 687338032Speter the sender address was unparseable for some reason; 687438032Speter this was supposed to fall back to the "return to 687538032Speter postmaster" case. 687638032Speter Improve aliaswait backoff algorithm. 687738032Speter Portability patches for Linux (8.6.3 required another header 687838032Speter file) (from Karl London) and SCO UNIX. 687938032Speter CONFIG: patch prog mailer to not strip host name off of envelope 688038032Speter addresses (so that it matches local again). From 688138032Speter Christopher Davis. 688238032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 688338032Speter this prevents uux from seeing lines with null names like 688438032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 688538032Speter Nakamura of Kyoto University. 688638032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 688738032Speter it shouldn't fail miserably. From Motonori Nakamura. 688838032Speter 688964562Sgshapiro8.6.2/8.6.2 1993/10/15 689038032Speter Put a "successful delivery" message in the transcript for 689138032Speter addresses that get return-receipts. 689238032Speter Put a prominent "this is only a warning" message in warning 689338032Speter messages -- some people don't read carefully enough 689438032Speter and end up sending the message several times. 689538032Speter Include reason for temporary failure in the "warning" return 689638032Speter message. Currently, it just says "cannot send for 689738032Speter four hours". 689838032Speter Fix the "Original message received" time generated for 689938032Speter returntosender messages. It was previously listed as 690038032Speter the current time. Bug reported by Eric Hagberg of 690138032Speter Cornell University Medical College. 690238032Speter If there is an error when writing the body of a message, 690338032Speter don't send the trailing dot and wait for a response 690438032Speter in sender SMTP, as this could cause the connection to 690538032Speter hang up under some bizarre circumstances. From Eric 690638032Speter Wassenaar. 690738032Speter Fix some server SMTP synchronization problems caused when 690838032Speter connections fail during message collection. From 690938032Speter Eric Wassenaar. 691038032Speter Fix a problem that can cause srvrsmtp to reject mail if the 691138032Speter name server is down -- it accepts the RCPT but rejects 691238032Speter the DATA command. Problem reported by Jim Murray of 691338032Speter Stratus. 691438032Speter Fix a problem that can cause core dumps if the config file 691538032Speter incorrectly resolves to a null hostname. Reported by 691638032Speter Allan Johannesen of WPI. 691738032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 691838032Speter by non-root users were not put into 691938032Speter X-Authentication-Warning:s as intended because the 692043730Speter config file hadn't set the PrivacyOptions yet. Fix 692138032Speter from Sven-Ove Westberg of the University of Lulea. 692238032Speter Under very odd circumstances, the alias file rebuild code 692338032Speter could get confused as to whether a database was 692438032Speter open or not. 692538032Speter Check "vendor code" on the end of V lines -- this is 692638032Speter intended to provide a hook for vendor-specific 692738032Speter configuration syntax. (This is a "new feature", 692838032Speter but I've made an exception to my rule in a belief 692938032Speter that this is a highly exceptional case.) 693038032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 693138032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 693238032Speter (from Jon Forrest of UC Berkeley) 693338032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 693438032Speter 693564562Sgshapiro8.6.1/8.6 1993/10/08 693638032Speter Portability fixes for A/UX and Encore UMAX V. 693738032Speter Fix error message handling -- if you had a name server down 693838032Speter causing an error during parsing, that message was never 693938032Speter propagated to the queue file. 694038032Speter 694164562Sgshapiro8.6/8.6 1993/10/05 694238032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 694338032Speter conf.h (other systems have the same bug). 694438032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 694538032Speter getdtablesize() instead of sysconf(); a disturbingly 694638032Speter large number of systems defined _SC_OPEN_MAX in the 694738032Speter header files but don't have the syscall. 694838032Speter Another patch to really truly ignore MX records in getcanonname 694938032Speter if trymx == FALSE. 695038032Speter Fix problem that caused the "250 IAA25499 Message accepted for 695138032Speter delivery" message to be omitted if there was an error 695238032Speter in the header of the message (e.g., a bad Errors-To: 695338032Speter line). Pointed out by Michael Corrigan of UCSD. 695438032Speter Announce name of host we are chatting when we get errors; this 695538032Speter is an IDA-ism suggested by Christophe Wolfhugel. 695638032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 695738032Speter Australian Artificial Intelligence Institute), SCO Unix 695838032Speter (from Murray Kucherawy of Hookup Communication Corp.), 695938032Speter NeXT (from Vince DeMarco and myself), Linux (from 696038032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 696138032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 696238032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 696338032Speter Some changes to get around gcc optimizer bugs. From Takahiro 696438032Speter Kanbe. 696538032Speter Fix error recovery in queueup if another tf file of the same 696638032Speter name already exists. Problem stumbled over by Bill 696738032Speter Wisner of The Well. 696838032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 696938032Speter Problem noted by Keith McMillan of Ameritech Services. 697038032Speter Deal with group permissions properly when opening .forward and 697138032Speter :include: files. This relaxes the 8.1C restrictions 697238032Speter slightly more. This includes proper setting of groups 697338032Speter when reading :include: files, allowing you to read some 697438032Speter files that you should be able to read but have previously 697538032Speter been denied unless you owned them or they had "other" 697638032Speter read permission. 697738032Speter Make certain that $j is in $=w (after the .cf is read) so that 697838032Speter if the user is forced to override some silly system, 697938032Speter MX suppression will still work. 698038032Speter Fix a couple of efficiency problems where newstr was double- 698138032Speter calling expensive routines. In at least one case, it 698238032Speter wasn't guaranteed that they would always return the 698338032Speter same result. Problem noted by Christophe Wolfhugel. 698438032Speter Fix null pointer dereference in putoutmsg -- only on an error 698538032Speter condition from a non-SMTP mailer. From Motonori 698638032Speter Nakamura. 698738032Speter Macro expand "C" line class definitions before scanning so that 698838032Speter "CX $Z" works. 698938032Speter Fix problem that caused error message to be sent while still 699038032Speter trying to send the original message if the connection 699138032Speter is closed during a DATA command after getting an error 699238032Speter on an RCPT command (pretty obscure). Problem reported 699338032Speter by John Myers of CMU. 699438032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 699538032Speter term bug. 699638032Speter Fix a nasty bug causing core dumps when returning the "warning: 699738032Speter cannot deliver for N hours -- will keep trying" message; 699843730Speter it only occurred if you had PostmasterCopy set and 699938032Speter only on some architectures. Although sendmail would 700038032Speter keep trying, it would send error messages on each 700138032Speter queue interval. This is an important fix. 700238032Speter Allow u and g options to take user and group names respectively. 700338032Speter Don't do a chdir into the queue directory in -bt mode to make 700438032Speter ruleset testing a bit easier. 700538032Speter Don't allow users to turn off logging (using -oL) on the command 700638032Speter line -- command line can only raise, not lower, logging 700738032Speter level. 700838032Speter Set $u to the original recipient on the SMTP transaction or on 700938032Speter the command line. This is only done if there is exactly 701038032Speter one recipient. Technically, this does not meet the 701138032Speter specs, because it does not guarantee a domain on the 701238032Speter address. 701338032Speter Fix a problem that dumped error messages on bad addresses if 701438032Speter you used the -t flag. Problem noted by Josh Smith of 701538032Speter Harvey Mudd College. 701638032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 701738032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 701838032Speter avoid the problem of people who use angle brackets in 701938032Speter their full name information. 702038032Speter Fix a null pointer dereference if you set option "l", have 702138032Speter an Errors-To: header in the message, and have Errors-To: 702238032Speter defined in the config file H lines. From J.R. Oldroyd. 702338032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 702438032Speter wrong when compiling. Suggested by Rick McCarty of TI. 702538032Speter Fix a problem that could pass negative SIZE parameter if the 702638032Speter df file got lost; this would cause servers to always 702738032Speter give a temporary failure, making the problem even worse. 702838032Speter Problem noted by Allan Johannesen of WPI. 702938032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 703038032Speter protocol timeouts (30s default). Requested by Murray 703138032Speter Kucherawy of HookUp Communication Corp. to handle bogus 703238032Speter PC TCP/IP implementations. 703338032Speter Change $w default definition to be just the first component of 703438032Speter the domain name on config level 5. The $j macro defaults 703538032Speter to the FQDN; $m remains as before. This lets well-behaved 703638032Speter config files use any of the short, long, or subdomain 703738032Speter names. 703838032Speter Add makesendmail script in src to try to automate multi-architecture 703938032Speter builds. I know, this is sub-optimal, but it is still 704038032Speter helpful. 704138032Speter Fix very obscure race condition that can cause a queue run to 704238032Speter get a queue file for an already completed job. This 704338032Speter problem has existed for years. Problem noted by the 704438032Speter long suffering Allan Johannesen of WPI. 704538032Speter Fix a problem that caused the raw sender name to be passed to 704638032Speter udbsender instead of the canonified name -- this caused 704738032Speter it to sometimes miss records that it should have found. 704838032Speter Relax check of name on HELO packet so that a program using -bs 704938032Speter that claims to be itself works properly. 705038032Speter Restore rewriting of $: part of address through 2, R, 4 in 705138032Speter buildaddr -- this requires passing a lot of flags to get 705238032Speter it right. Unlike old versions, this ONLY rewrites 705338032Speter recipient addresses, not sender addresses. 705438032Speter Fix a bug that caused core dumps in config files that cannot 705538032Speter resolve /file/name style addresses. Fix from Jonathan 705638032Speter Kamens of OpenVision Technologies. 705738032Speter Fix problem with fcntl locking that can cause error returns to 705838032Speter be lost if the lock is lost; this required fully 705938032Speter queueing everything, dropping the envelope (so errors 706038032Speter would get returned), and then re-reading the queue from 706138032Speter scratch. 706238032Speter Fix a problem that caused aliases that redefine an otherwise 706338032Speter true address to still send to the original address 706438032Speter if and only if the alias failed in certain bizarre 706538032Speter ways (e.g, if they pointed at a list:; syntax address). 706638032Speter Problem pointed out by Jonathan Kamens. 706738032Speter Remove support for frozen configuration files. They caused 706838032Speter more trouble than it was worth. 706938032Speter Fix problem that can cause error messages to get ignored when 707038032Speter using both -odb and -t flags. Problem noted by Rob 707138032Speter McNicholas at U.C. Berkeley. 707238032Speter Include all "normal" variations on hostname in $=w. For example, 707338032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 707438032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 707538032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 707638032Speter the queue. 707738032Speter Reset SmtpPhase global on initial connection creation so that 707838032Speter messages don't come out with stale information. 707938032Speter Pass an "ext" argument to lockfile so that error/log messages 708038032Speter will properly reflect the true filename being locked. 708138032Speter Put all [...] address forms into $=w -- this eliminates the need 708238032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 708338032Speter Myers of CMU. 708438032Speter Fix a bug that can cause qf files to be left around even after 708538032Speter an SMTP RSET command. Problem and fix from Michael 708638032Speter Corrigan. 708743730Speter Don't send a PostmasterCopy to errors when the Precedence: is 708838032Speter negative. Error reports still go to the envelope 708938032Speter sender address. 709038032Speter Add LA_SHORT for load averages. 709138032Speter Lock sendmail.st file when posting statistics. 709238032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 709338032Speter set the size of the TCP send and receive buffers; if you 709438032Speter run over a slow slip line you may need to set these down 709538032Speter (although it would be better to fix the SLIP implementation 709638032Speter so that it's not necessary to recompile every program 709738032Speter that does bulk data transfer). 709838032Speter Allow null defaults on $( ... $) lookups. Problem reported by 709938032Speter Amir Plivatsky. 710038032Speter Diagnose crufty S and V config lines. This resulted from an 710138032Speter observation that some people were using the SITE macro 710238032Speter without the SITECONFIG macro first, which was causing 710338032Speter bogus config files that were not caught. 710438032Speter Fix makemap -f flag to turn off case folding (it was turning it 710538032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 710638032Speter Fix a problem that caused multiple error messages to be sent if 710738032Speter you used "sendmail -t -oem -odb", your system uses fcntl 710838032Speter locking, and one of the recipient addresses is unknown. 710938032Speter Reset uid earlier in include() so that recursive .forwards or 711038032Speter :include:s don't use the wrong uid. 711138032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 711238032Speter called, the code to recover the descriptor was broken. 711338032Speter This sometimes (only sometimes) caused problems with the 711438032Speter alias file. Fix from Motonori Nakamura. 711538032Speter Fix a problem that caused aliaswait to go into infinite recursion 711638032Speter if the @:@ metasymbol wasn't found in the alias file. 711738032Speter Improve error message on newaliases if database files cannot be 711838032Speter opened or if running with no database format defined. 711938032Speter Do a better estimation of the size of error messages when NoReturn 712038032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 712138032Speter Fix a problem causing the "c" option (don't connect to expensive 712238032Speter mailers) to be ignored in SMTP. Problem noted and the 712338032Speter solution suggested by Robert Elz of The University of 712438032Speter Melbourne. 712538032Speter Improve connection caching algorithm by passing "[host]" to 712638032Speter hostsignature, which strips the square brackets and 712738032Speter returns the real name. This allows mailertable entries 712838032Speter to match regular entries. 712938032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 713038032Speter feature, even if it doesn't work right. 713138032Speter Catch and log attempts to try the "wiz" command in server SMTP. 713238032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 713338032Speter Be more generous at assigning $z to the home directory -- do this 713438032Speter for programs that are specified through a .forward file. 713538032Speter Fix from Andrew Chang of Sun Microsystems. 713638032Speter Always save a fatal error message in preference to a non-fatal 713738032Speter error message so that the "subject" line of return 713838032Speter messages is the best possible. 713938032Speter CONFIG: reduce the number of quotes needed to quote configuration 714038032Speter parameters with commas: two quotes should work now, e.g., 714138032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 714238032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 714338032Speter connections (domain-ized UUCP). 714438032Speter CONFIG: fix bug in default maps (-o must be before database file 714564562Sgshapiro name). Pointed out by Christophe Wolfhugel. 714638032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 714738032Speter DNS. This would presumably be used in UUCP islands. 714838032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 714938032Speter CONFIG: log $u in Received: line. This is in technical violation 715038032Speter of the standards, since it doesn't guarantee a domain 715138032Speter on the address. 715238032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 715338032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 715438032Speter the "m" flag should you want it. Apparently some Solaris 2.2 715538032Speter installations can't handle multiple local recipients. 715638032Speter Problem noted by Josh Smith. 715738032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 715838032Speter CONFIG: change default version level from 4 to 5. 715938032Speter CONFIG: add FEATURE(nullclient) to create a config file that 716038032Speter forwards all mail to a hub without ever looking at the 716138032Speter addresses in any detail. 716238032Speter CONFIG: properly strip mailer: information off of relays when 716338032Speter used to change .BITNET form into %-hack form. 716438032Speter CONFIG: fix a problem that caused infinite loops if presented 716538032Speter with an address such as "!foo". 716638032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 716738032Speter the reverse "PTR" mapping is broken. There's a better 716838032Speter way to do this, but the change is fairly major and I 716938032Speter want to hold it for another release. Problem noted by 717038032Speter Bret Marquis. 717138032Speter 717264562Sgshapiro8.5/8.5 1993/07/23 717338032Speter Serious bug: if you used a command line recipient that was unknown 717438032Speter sendmail would not send a return message (it was treating 717538032Speter everything as though it had an SMTP-style client that 717638032Speter would do the return itself). Problem noted by Josh Smith. 717738032Speter Change "trymx" option in getcanonname() to ignore all MX data, 717838032Speter even during a T_ANY query. This actually didn't break 717938032Speter anything, because the only time you called getcanonname 718038032Speter with !trymx was if you already knew there were no MX 718138032Speter records, but it is somewhat cleaner. From Motonori 718238032Speter Nakamura. 718338032Speter Don't call getcanonname from getmxrr if you already know there 718438032Speter are no DNS records matching the name. 718538032Speter Fix a problem causing error messages to always include "The 718638032Speter original message was received ... from localhost". 718738032Speter The correct original host information is now included. 718838032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 718938032Speter version of "test" doesn't have the -x flag). Change it 719038032Speter to use -f instead. From John Myers. 719138032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 719238032Speter esmtp -- it should be smtp. 719338032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 719438032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 719538032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 719638032Speter this cleans up the configs somewhat. This fixes a serious 719738032Speter problem that caused route-addrs to get mistaken as relays, 719838032Speter pointed out by John Myers. WARNING: this also causes 719938032Speter the default on SMART_HOST to change from "suucp" to 720038032Speter "relay" if you have MAILER(smtp) specified. 720138032Speter 720264562Sgshapiro8.4/8.4 1993/07/22 720338032Speter Add option `w'. If you receive a message that comes to you because 720438032Speter you are the best (lowest preference) target of an MX, and 720538032Speter you haven't explicitly recognized the source MX host in 720638032Speter your .cf file, this option will cause you to try the target 720738032Speter host directly (as if there were no MX for it at all). If 720838032Speter `w' is not set, this case is a configuration error. 720938032Speter Beware: if `w' is set, senders may get bogus errors like 721038032Speter "message timed out" or "host unknown" for problems that 721138032Speter are really configuration errors. This option is 721238032Speter disrecommended, provided only for compatibility with 721338032Speter UIUC sendmail. 721438032Speter Fix a problem that caused the incoming socket to be left open 721538032Speter when sendmail forks after the DATA command. This caused 721638032Speter calling systems to wait in FIN_WAIT_2 state until the 721738032Speter entire list was processed and the child closed -- a 721838032Speter potentially prodigious amount of time. Problem noted 721938032Speter by Neil Rickert. 722038032Speter Fix problem (created in 6.64) that caused mail sent to multiple 722138032Speter addresses, one of which was a bad address, to completely 722238032Speter suppress the sending of the message. This changes 722338032Speter handling of EF_FATALERRS somewhat, and adds an 722438032Speter EF_GLOBALERRS flag. This also fixes a potential problem 722538032Speter with duplicate error messages if there is a syntax error 722638032Speter in the header of a message that isn't noticed until late 722738032Speter in processing. Original problem pointed out by Josh Smith 722838032Speter of Harvey Mudd College. This release includes quite a bit 722938032Speter of dickering with error handling (see below). 723038032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 723138032Speter will only hurt already-broken software and should help 723238032Speter humans. 723338032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 723438032Speter compiled in. It would never read the alias file. 723538032Speter Repair unbalanced `)' and `>' (the "open" versions are already 723638032Speter repaired). 723738032Speter Logging of "done" in dropenvelope() was incorrect: it would 723838032Speter log this even when the queue file still existed. Change 723938032Speter this to only log "done" (at log level 11) when the 724038032Speter queue file is actually removed. From John Myers. 724138032Speter Log "lost connection" in server SMTP at log level 20 if there 724238032Speter is no pending transaction. Some senders just close the 724338032Speter connection rather than sending QUIT. 724438032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 724538032Speter domains that do not have MX records -- this would cause 724638032Speter the subsequent host name lookup to fail. The problem 724738032Speter only occurred if you had FEATURE(nocanonify) set. 724838032Speter Problem noted by Rick McCarty of Texas Instruments. 724938032Speter Fix invocation of setvbuf when passed a -X flag -- I had 725038032Speter unwittingly used an ANSI C extension, and this caused 725138032Speter core dumps on some machines. 725238032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 725338032Speter Previously it just gave an empty send queue, which 725438032Speter then gave either "Need RCPT (recipient)" at the DATA 725538032Speter (confusing, since you had given an RCPT command which 725638032Speter returned 250) or just dropped the email, depending on 725738032Speter whether you were running VERBose mode. Now it usually 725838032Speter diagnoses this case as "aliasing/forwarding loop broken". 725938032Speter Unfortunately, it still doesn't adequately diagnose 726038032Speter some true error conditions. 726138032Speter Add internal concept of "warning messages" using 6xx codes. 726238032Speter These are not reported only to Postmaster. Unbalanced 726338032Speter parens, brackets, and quotes are printed as 653 codes. 726438032Speter They are always mapped to 5xx codes before use in SMTP. 726538032Speter Clean up error messages to tell both the actual address that 726638032Speter failed and the alias they arose from. This makes it 726738032Speter somewhat easier to diagnose problems. Difficulty noted 726838032Speter by Motonori Nakamura. 726938032Speter Fix a problem that inappropriately added a ctladdr to addresses 727038032Speter that shouldn't have had one during a queue run. This 727138032Speter caused error messages to be handled differently during 727238032Speter a queue run than a direct run. 727338032Speter Don't print the qf name and line number if you get errors during 727438032Speter the direct run of the queue from srvrsmtp -- this was 727538032Speter just extra stuff for users to crawl through. 727638032Speter Put command line flags on second line of pid file so you can 727738032Speter auto-restart the daemon with all appropriate arguments. 727838032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 727938032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 728038032Speter restart it. 728138032Speter Remove the ``setuid(getuid())'' in main -- this caused the 728238032Speter IDENT daemon to screw up. This required that I change 728338032Speter HASSETEUID to HASSETREUID and complicate the mode 728438032Speter changing somewhat because both Ultrix and SunOS seem 728538032Speter to have a bug causing seteuid() to set the saved uid 728638032Speter as well as the effective. The program test/t_setreuid.c 728738032Speter will test to see if your implementation of setreuid(2) 728838032Speter is appropriately functional. 728938032Speter The FallBackMX (option V) handling failed to properly identify 729038032Speter fallback to yourself -- most of the code was there, 729138032Speter but it wasn't being enabled. Problem noted by Murray 729238032Speter Kucherawy of the University of Waterloo. 729338032Speter Change :include: open timeout from ETIMEDOUT to an internal 729438032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 729538032Speter with CurHostName" in error messages, which can be 729638032Speter confusing. Reported by Jonathan Kamens of OpenVision 729738032Speter Technologies. 729838032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 729938032Speter process group id. The original fix was to get around 730038032Speter some problems with recalcitrant MUAs, but it breaks 730138032Speter any call from a shell that creates a process group id 730238032Speter different from the process id. I could try to fix 730338032Speter this by diddling the tty owner (using tcsetpgrp or 730438032Speter equivalent) but this is too likely to break other 730538032Speter things. 730638032Speter Portability changes: 730738032Speter Support -M as equivalent to -oM on Ultrix -- apparently 730838032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 730938032Speter instead of using standard flags. Oh joy. This 731043730Speter behavior reported by Jon Giltner of University 731138032Speter of Colorado. 731238032Speter SGI IRIX -- this includes several changes that should 731338032Speter help other strict ANSI compilers. 731438032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 731538032Speter Corporation. 731638032Speter Solaris running the Sun C compiler (which despite the 731738032Speter documentation apparently doesn't define 731838032Speter __STDC__ by default). 731938032Speter ConvexOS from Eric Schnoebelen of Convex. 732038032Speter Sony NEWS workstations and Omron LUNA workstations from 732138032Speter Motonori Nakamura. 732238032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 732338032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 732438032Speter several people have made a good argument that this 732538032Speter creates more problems than it solves (although this 732638032Speter may prove painful in the short run). 732738032Speter CONFIG: generalize all the relays to accept a "mailer:host" 732838032Speter format. 732938032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 733038032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 733138032Speter addresses are also passed through this ruleset. 733238032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 733338032Speter internet-style addresses would "fall off the end" of 733438032Speter ruleset zero and be interpreted as local -- however, 733538032Speter the angle brackets confused the recursive call. 733638032Speter These are now diagnosed as "Unrecognized host name". 733738032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 733838032Speter ifdef(`_MAILER_USENET_') instead of 733938032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 734038032Speter of SINTEF RUNIT, Oslo. 734138032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 734238032Speter early in ruleset 0; this allows .mc authors to bypass 734338032Speter things like the "short circuit" code for local addresses. 734438032Speter Prompted by a comment by Bill Wisner of The Well. 734538032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 734638032Speter esmtp) to send SMTP mail. This allows you to default 734738032Speter to esmtp but use a mailertable or other override to 734838032Speter deal with broken servers. This logic was pointed out 734938032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 735038032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 735138032Speter environments. Ugly as sin. 735238032Speter 735364562Sgshapiro8.3/8.3 1993/07/13 735438032Speter Fix setuid problems introduced in 8.2 that caused messages 735538032Speter like "Cannot create qfXXXXXX: Invalid argument" 735638032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 735738032Speter involved a new compile flag "HASSETEUID" that takes 735838032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 735938032Speter that the POSIX interface is broken enough to break 736038032Speter some systems badly. This includes some fixes for 736138032Speter HP-UX. Also fixes problems where the real uid is 736238032Speter not reset properly on startup (from Neil Rickert). 736338032Speter Fix a problem that caused timed out messages to not report the 736438032Speter addresses that timed out. Error messages are also more 736538032Speter "user friendly". 736638032Speter Drop required bandwidth on connections from 64 bytes/sec to 736738032Speter 16 bytes/sec. 736838032Speter Further Solaris portability changes -- doesn't require the BSD 736938032Speter compatibility library. This also adds a new 737038032Speter "HASGETDTABLESIZE" compile flag which can be used if 737138032Speter you want to use getdtablesize(2) instead of sysconf(2). 737238032Speter These are loosely based on changes from David Meyer at 737338032Speter University of Oregon. This now seems to work, at least 737438032Speter for quick test cases. 737538032Speter Fix a problem that can cause duplicate error messages to be 737638032Speter sent if you are in SMTP, you send to multiple addresses, 737738032Speter and at least one of those addresses is good and points 737838032Speter to an account that has a .forward file (whew!). 737938032Speter Fix a problem causing messages to be discarded if checkcompat() 738038032Speter returned EX_TEMPFAIL (because it didn't properly mark 738138032Speter the "to" address). Problem noted by John Myers. 738238032Speter Fix dfopen to return NULL if the open failed; I was depending 738338032Speter on fdopen(-1) returning NULL, which isn't the case. This 738438032Speter isn't serious, but does result in weird error diagnoses. 738538032Speter From Michael Corrigan. 738638032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 738738032Speter messages sent through UUCP-family mailers. Suggested 738838032Speter by Bill Wisner of The Well. 738938032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 739038032Speter include a "uucp-dom" mailer that uses domain-style 739138032Speter addressing. Suggested by Bill Wisner. 739238032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 739338032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 739438032Speter Christophe Wolfhugel. 739538032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 739638032Speter 739764562Sgshapiro8.2/8.2 1993/07/11 739838032Speter Don't drop out on config file parse errors in -bt mode. 739938032Speter On older configuration files, assume option "l" (use Errors-To 740038032Speter header) for back compatibility. NOTE: this DOES NOT 740138032Speter imply an endorsement of the Errors-To: header in any way. 740238032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 740338032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 740438032Speter SMTP server to give an error on this command, and 740538032Speter logging it in the transcript can be confusing. Fix 740638032Speter from Bill Wisner. 740738032Speter IRIX compatibility changes provided by Dan Rich 740838032Speter <drich@sandman.lerc.nasa.gov>. 740938032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 741038032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 741138032Speter <juo@klinzhai.rutgers.edu> 741238032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 741338032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 741438032Speter match the other flags in that file. 741538032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 741638032Speter Save h_errno in mci struct and improve error message display. 741738032Speter Changes from Eric Wassenaar. 741838032Speter Open /dev/null for the transcript if the create of the xf file 741938032Speter failed; this avoids at least one possible null pointer 742038032Speter reference in very weird cases. From Eric Wassenaar. 742138032Speter Clean up statistics gathering; it was over-reporting because of 742238032Speter forks. From Eric Wassenaar. 742338032Speter Fix problem that causes old Return-Path: line to override new 742438032Speter Return-Path: line (conf.c needs H_FORCE to avoid 742538032Speter re-using old value). From Motonori Nakamura. 742638032Speter Fix broken -m flag in K definition -- even if -m (match only) 742738032Speter was specified, it would still replace the key with the 742838032Speter value. Noted by Rick McCarty of Texas Instruments. 742938032Speter If the name server timed out over several days, no "timed out" 743038032Speter message would ever be sent back. The timeout code 743138032Speter has been moved from markfailure() to dropenvelope() 743238032Speter so that all such failures should be diagnosed. Pointed 743338032Speter out by Christophe Wolfhugel and others. 743438032Speter Relax safefile() constraints: directories in an include or 743538032Speter forward path must be readable by self if the controlling 743638032Speter user owns the entry, readable by all otherwise (e.g., 743738032Speter when reading your .forward file, you have to own and 743838032Speter have X permission in it; everyone needs X permission in 743938032Speter the root and directories leading up to your home); 744038032Speter include files must be readable by anyone, but need not 744138032Speter be owned by you. 744238032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 744338032Speter reading a .forward file; this gets around some problems 744438032Speter on NFS mounts if root permission is not exported and 744538032Speter the user's home directory isn't x'able. 744638032Speter Additional NeXT portability enhancements from Axel Zinser. 744738032Speter Additional HP-UX portability enhancements from Brian Bullen. 744838032Speter Add a timeout around SMTP message writes; this assumes you can 744938032Speter get throughput of at least 64 bytes/second. Note that 745038032Speter this does not impact the "datafinal" default, which 745138032Speter is separate; this is just intended to work around 745238032Speter network clogs that will occur before the final dot 745338032Speter is sent. From Eric Wassenaar. 745438032Speter Change map code to set the "include null" flag adaptively -- 745538032Speter it initially tries both, but if it finds anything 745638032Speter matching without a null it never tries again with a 745738032Speter null and vice versa. If -N is specified, it never 745838032Speter tries without the null and creates new maps with a 745938032Speter null byte. If -O is specified, it never tries with 746038032Speter the null (for efficiency). If -N and -O are specified, 746138032Speter you get -NO (get it?) lookup at all, so this would 746238032Speter be a bad idea. If you don't specify either -N or -O, 746338032Speter it adapts. 746438032Speter Fix recognition of "same from address" so that MH submissions 746538032Speter will insert the appropriate full name information; 746638032Speter this used to work and got broken somewhere along the 746738032Speter way. 746838032Speter Some changes to eliminate some unnecessary SYSERRs in the 746938032Speter log. For example, if you lost a connection, don't 747038032Speter bother reporting that fact on the connection you lost. 747138032Speter Add some "extended debugging" flags to try to track down 747238032Speter why we get occasional problems with file descriptor 747338032Speter one being closed when execing a mailer; it seems to 747438032Speter only happen when there has been another error in the 747538032Speter same transaction. This requires XDEBUG, defined 747638032Speter by default in conf.h. 747738032Speter Add "-X filename" command line flag, which logs both sides of 747838032Speter all SMTP transactions. This is intended ONLY for 747938032Speter debugging bad implementations of other mailers; start 748038032Speter it up, send a message from a mailer that is failing, 748138032Speter and then kill it off and examine the indicated log. 748238032Speter This output is not intended to be particularly human 748338032Speter readable. This also adds the HASSETVBUF compile 748438032Speter flag, defaulted on if your compiler defines __STDC__. 748538032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 748638032Speter have a local net that should get direct connects, you 748738032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 748838032Speter See cf/README for an example. 748938032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 749038032Speter sites that don't use the -d flag. 749138032Speter CONFIG: hide recipient addresses as well as sender addresses 749238032Speter behind $M if FEATURE(allmasquerade) is specified; this 749338032Speter has been requested by several people, but can break 749438032Speter local aliases. For example, if you mail to "localalias" 749538032Speter this will be rewritten as "localalias@masqueradehost"; 749638032Speter although initial delivery will work, replies will be 749738032Speter broken. Use it sparingly. 749838032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 749938032Speter to qualified domains in headers. I believe this is 750038032Speter largely equivalent to the IDA feature of the same name. 750138032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 750238032Speter to override the "system name" as your UUCP name -- 750338032Speter in particular, to use domain-ized UUCP names. From 750438032Speter Bill Wisner of The Well. 750538032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 750638032Speter first. This is currently unused in the config files, 750738032Speter but could be used in a mailertable entry. 750838032Speter 750964562Sgshapiro8.1C/8.1B 1993/06/27 751038032Speter Serious security bug fix: it was possible to read any file on 751138032Speter the system, regardless of ownership and permissions. 751238032Speter If a subroutine returns a fully qualified address, return it 751338032Speter immediately instead of feeding it back into rewriting. 751438032Speter This fixes a problem with mailertable lookups. 751538032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 751638032Speter 751764562Sgshapiro8.1B/8.1A 1993/06/12 751838032Speter Serious bug fix: pattern matching backup algorithm stepped by 751938032Speter two tokens in classes instead of one. Found by Claus 752038032Speter Assmann at University of Kiel, Germany. 752138032Speter 752264562Sgshapiro8.1A/8.1A 1993/06/08 752338032Speter Another mailertable fix.... 752438032Speter 752564562Sgshapiro8.1/8.1 1993/06/07 752638032Speter 4.4BSD freeze.
