This could terminate the current process without 1280785Sgshapiro starting a new daemon. Problem reported by Wolfgang Breyha 1380785Sgshapiro of SE Netway Communications. 1480785Sgshapiro Only apply MaxHeadersLength when receiving a message via SMTP or 1580785Sgshapiro the command line. Problem noted by Andrey J. Melnikoff. 1680785Sgshapiro When finding the system's local hostname on an IPv6-enabled system 1780785Sgshapiro which doesn't have any IPv6 interface addresses, fall back 1880785Sgshapiro to looking up only IPv4 addresses. Problem noted by Tim 1980785Sgshapiro Bosserman of EarthLink. 2080785Sgshapiro When commands were being rejected due to check_relay or TCP 2180785Sgshapiro Wrappers, the ETRN command was not giving a response. 2280785Sgshapiro Incoming IPv4 connections on a Family=inet6 daemon (using 2380785Sgshapiro IPv4-mapped addresses) were incorrectly labeled as "may be 2480785Sgshapiro forged". Problem noted by Per Steinar Iversen of Oslo 2580785Sgshapiro University College. 2680785Sgshapiro Shutdown address test mode cleanly on SIGTERM. Problem noted by 2780785Sgshapiro Greg King of the OAO Corporation. 2880785Sgshapiro Restore the original real uid (changed in main() to prevent 2980785Sgshapiro out of band signals) before invoking a delivery agent. 3080785Sgshapiro Some delivery agents use this for the "From " envelope 3180785Sgshapiro "header". Problem noted by Leslie Carroll of the 3280785Sgshapiro University at Albany. 3380785Sgshapiro Mark closed file descriptors properly to avoid reuse. Problem 3480785Sgshapiro noted by Jeff Bronson of J.D. Bronson, Inc. 3580785Sgshapiro Setting Timeout options on the command line will also override 3680785Sgshapiro their sub-suboptions in the .cf file, e.g., -O 3780785Sgshapiro Timeout.queuereturn=2d will set all queuereturn timeouts 3880785Sgshapiro to 2 days. Problem noted by Roger B.A. Klorese. 3980785Sgshapiro Portability: 4080785Sgshapiro BSD/OS has a broken setreuid() implementation. Problem 4180785Sgshapiro noted by Vernon Schryver of Rhyolite Software. 4280785Sgshapiro BSD/OS has /dev/urandom(4) (as of version 4.1/199910 ?). 4380785Sgshapiro Noted by Vernon Schryver of Rhyolite Software. 4480785Sgshapiro BSD/OS has fchown(2). Noted by Dave Yadallee of Netline 4580785Sgshapiro 2000 Internet Solutions Inc. 4680785Sgshapiro Solaris 2.X and later have strerror(3). From Sebastian 4780785Sgshapiro Hagedorn of Cologne University. 4880785Sgshapiro CONFIG: Fix parsing for IPv6 domain literals in addresses 4980785Sgshapiro (user@[IPv6:address]). Problem noted by Liyuan Zhou. 5080785Sgshapiro 5177349Sgshapiro8.11.4/8.11.4 2001/05/28 5277349Sgshapiro Clean up signal handling routines to reduce the chances of heap 5377349Sgshapiro corruption and other potential race conditions. 5477349Sgshapiro Terminating and restarting the daemon may not be 5577349Sgshapiro instantaneous due to this change. Also, non-root users can 5677349Sgshapiro no longer send out-of-band signals. Problem reported by 5777349Sgshapiro Michal Zalewski of BindView. 5877349Sgshapiro If LogLevel is greater than 9 and SASL fails to negotiate an 5977349Sgshapiro encryption layer, avoid core dump logging the encryption 6077349Sgshapiro strength. Problem noted by Miroslav Zubcic of Crol. 6177349Sgshapiro If a server offers "AUTH=" and "AUTH " and the list of mechanisms is 6277349Sgshapiro different in those two lines, sendmail might not have 6377349Sgshapiro recognized (and used) all of the offered mechanisms. 6477349Sgshapiro Fix an IP address lookup problem on Solaris 2.0 - 2.3. Patch 6577349Sgshapiro from Kenji Miyake. 6677349Sgshapiro This time, really don't use the .. directory when expanding 6777349Sgshapiro QueueDirectory wildcards. 6877349Sgshapiro If a process is interrupted while closing a map, don't try to close 6977349Sgshapiro the same map again while exiting. 7077349Sgshapiro Allow local mailers (F=l) to contact remote hosts (e.g., via 7177349Sgshapiro LMTP). Problem noted by Norbert Klasen of the University 7277349Sgshapiro of Tuebingen. 7377349Sgshapiro If Timeout.QueueReturn was set to a value less the time it took 7477349Sgshapiro to write a new queue file (e.g., 0 seconds), the bounce 7577349Sgshapiro message would be lost. Problem noted by Lorraine L Goff of 7677349Sgshapiro Oklahoma State University. 7777349Sgshapiro Pass map argument vector into map rewriting engine for the regex 7877349Sgshapiro and prog map types. Problem noted by Stephen Gildea of 7977349Sgshapiro InTouch Systems, Inc. 8077349Sgshapiro When closing an LDAP map due to a temporary error, close all of the 8177349Sgshapiro other LDAP maps which share the original map's connection 8277349Sgshapiro to the LDAP server. Patch from Victor Duchovni of 8377349Sgshapiro Morgan Stanley. 8477349Sgshapiro To detect changes of NDBM aliases files check the timestamp of the 8577349Sgshapiro .pag file instead of the .dir file. Problem noted by Neil 8677349Sgshapiro Rickert of Northern Illinois University. 8777349Sgshapiro Don't treat temporary hesiod lookup failures as permanent. Patch 8877349Sgshapiro from Werner Wiethege. 8977349Sgshapiro If ClientPortOptions is set, make sure to create the outgoing socket 9077349Sgshapiro with the family set in that option. Patch from Sean Farley. 9177349Sgshapiro Avoid a segmentation fault trying to dereference a NULL pointer 9277349Sgshapiro when logging a MaxHopCount exceeded error with an empty 9377349Sgshapiro recipient list. Problem noted by Chris Adams of HiWAAY 9477349Sgshapiro Internet Services. 9577349Sgshapiro Fix DSN for "Too many hops" bounces. Problem noticed by Ulrich 9677349Sgshapiro Windl of the Universitaet Regensburg. 9777349Sgshapiro Fix DSN for "mail loops back to me" bounces. Problem noticed by 9877349Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 9977349Sgshapiro Portability: 10077349Sgshapiro OpenBSD has a broken setreuid() implementation. 10177349Sgshapiro CONFIG: Undo change from 8.11.1: change 501 SMTP reply code back 10277349Sgshapiro to 553 since it is allowed by DRUMS. 10377349Sgshapiro CONFIG: Add OSTYPE(freebsd4) for FreeBSD 4.X. 10477349Sgshapiro DEVTOOLS: install.sh did not properly handle paths in the source 10577349Sgshapiro file name argument. Noted by Kari Hurtta of the Finnish 10677349Sgshapiro Meteorological Institute. 10777349Sgshapiro DEVTOOLS: Add FAST_PID_RECYCLE to compile time options for OpenBSD 10877349Sgshapiro since it generates random process ids. 10977349Sgshapiro PRALIASES: Add back adaptive algorithm to deal with different endings 11077349Sgshapiro of entries in the database (with/without trailing '\0'). 11177349Sgshapiro Patch from John Beck of Sun Microsystems. 11277349Sgshapiro New Files: 11377349Sgshapiro cf/ostype/freebsd4.m4 11477349Sgshapiro 11573188Sgshapiro8.11.3/8.11.3 2001/02/27 11673188Sgshapiro Prevent a segmentation fault when a bogus value was used in the 11773188Sgshapiro LDAPDefaultSpec option's -r, -s, or -M flags and if a bogus 11873188Sgshapiro option was used. Problem noted by Allan E Johannesen of 11973188Sgshapiro Worcester Polytechnic Institute. 12073188Sgshapiro Prevent "token too long" message by shortening {currHeader} which 12173188Sgshapiro could be too long if the last copied character was a quote. 12273188Sgshapiro Problem detected by Jan Krueger of digitalanswers 12373188Sgshapiro communications consulting gmbh. 12473188Sgshapiro Additional IPv6 check for unspecified addresses. Patch from 12573188Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 12673188Sgshapiro Do not ignore the ClientPortOptions setting if DaemonPortOptions 12773188Sgshapiro Modifier=b (bind to same interface) is set and the 12873188Sgshapiro connection came in from the command line. 12973188Sgshapiro Do not bind to the loopback address if DaemonPortOptions 13073188Sgshapiro Modifier=b (bind to same interface) is set. Patch from 13173188Sgshapiro John Beck of Sun Microsystems. 13273188Sgshapiro Properly deal with open failures on non-optional maps used in 13373188Sgshapiro check_* rulesets by returning a temporary failure. 13473188Sgshapiro Buffered file I/O files were not being properly fsync'ed to disk 13573188Sgshapiro when they were committed. 13673188Sgshapiro Properly encode '=' for the AUTH= parameter of the MAIL command. 13773188Sgshapiro Problem noted by Hadmut Danisch. 13873188Sgshapiro Under certain circumstances the macro {server_name} could be set 13973188Sgshapiro to the wrong hostname (of a previous connection), which may 14073188Sgshapiro cause some rulesets to return wrong results. This would 14173188Sgshapiro usually cause mail to be queued up and delivered later on. 14273188Sgshapiro Ignore F=z (LMTP) mailer flag if $u is given in the mailer A= 14373188Sgshapiro equate. Problem noted by Motonori Nakamura of Kyoto 14473188Sgshapiro University. 14573188Sgshapiro Work around broken accept() implementations which only partially 14673188Sgshapiro fill in the peer address if the socket is closed before 14773188Sgshapiro accept() completes. 14873188Sgshapiro Return an SMTP "421" temporary failure if the data file can't be 14973188Sgshapiro opened where the "354" reply would normally be given. 15073188Sgshapiro Prevent a CPU loop in trying to expand a macro which doesn't exist 15173188Sgshapiro in a queue run. Problem noted by Gordon Lack of Glaxo 15273188Sgshapiro Wellcome. 15373188Sgshapiro If delivering via a program and that program exits with EX_TEMPFAIL, 15473188Sgshapiro note that fact for the mailq display instead of just showing 15573188Sgshapiro "Deferred". Problem noted by Motonori Nakamura of Kyoto 15673188Sgshapiro University. 15773188Sgshapiro If doing canonification via /etc/hosts, try both the fully 15873188Sgshapiro qualified hostname as well as the first portion of the 15973188Sgshapiro hostname. Problem noted by David Bremner of the 16073188Sgshapiro University of New Brunswick. 16173188Sgshapiro Portability: 16273188Sgshapiro Fix a compilation problem for mail.local and rmail if SFIO 16373188Sgshapiro is in use.

Miller of Courtesan Consulting. 17073188Sgshapiro Unixware 7.1.1 doesn't allow h_errno to be set directly if 17173188Sgshapiro sendmail is being compiled with -kthread. Problem 17273188Sgshapiro noted by Orion Poplawski of CQG, Inc. 17373188Sgshapiro CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and 17473188Sgshapiro current left hand side for $LHS in virtuser files. 17573188Sgshapiro DEVTOOLS: Do not pass make targets to recursive Build invocations. 17673188Sgshapiro Problem noted by Jeff Bronson of J.D. Bronson, Inc. 17773188Sgshapiro MAIL.LOCAL: In LMTP mode, do not return errors regarding problems 17873188Sgshapiro storing the temporary message file until after the remote 17973188Sgshapiro side has sent the final DATA termination dot. Problem 18073188Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic 18173188Sgshapiro Institute. 18273188Sgshapiro MAIL.LOCAL: If LMTP mode is set, give a temporary error if users 18373188Sgshapiro are also specified on the command line. Patch from 18473188Sgshapiro Motonori Nakamura of Kyoto University. 18573188Sgshapiro PRALIASES: Skip over AliasFile specifications which aren't based on 18673188Sgshapiro database files (i.e., only show dbm, hash, and btree). 18773188Sgshapiro Renamed Files: 18873188Sgshapiro devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x 18973188Sgshapiro 19071345Sgshapiro8.11.2/8.11.2 2000/12/29 19171345Sgshapiro Prevent a segmentation fault when trying to set a class in 19271345Sgshapiro address test mode due to a negative array index. Audit 19371345Sgshapiro other array indexing. This bug is not believed to be 19471345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 19571345Sgshapiro Schools" project (IdS). 19671345Sgshapiro Add an FFR (for future release) to drop privileges when using 19771345Sgshapiro address test mode. This will be turned on in 8.12. It can 19871345Sgshapiro be enabled by compiling with: 19971345Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 20071345Sgshapiro in your devtools/Site/site.config.m4 file. Suggested by 20171345Sgshapiro Michal Zalewski of the "Internet for Schools" project (IdS). 20271345Sgshapiro Fix potential problem with Cyrus-SASL security layer which may have 20371345Sgshapiro caused I/O errors, especially for mechanism DIGEST-MD5. 20471345Sgshapiro When QueueSortOrder was set to host, sendmail might not read 20571345Sgshapiro enough of the queue file to determine the host, making the 20671345Sgshapiro sort sub-optimal. Problem noted by Jeff Earickson of 20771345Sgshapiro Colby College. 20871345Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 20971345Sgshapiro RFC 1891) but don't have FAILURE as value. 21071345Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 21171345Sgshapiro This implies that every change to SASL related files requires 21271345Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 21371345Sgshapiro mechanisms (in form of shared libraries). 21471345Sgshapiro Properly set the STARTTLS related macros during a queue run for 21571345Sgshapiro a cached connection. Bug reported by Michael Kellen of 21671345Sgshapiro NxNetworks, Inc. 21771345Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 21871345Sgshapiro client name. 21971345Sgshapiro Include original length of bad field/header when reporting 22071345Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 22171345Sgshapiro the Universitat Regensburg. 22271345Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 22371345Sgshapiro DeliveryMode queue. Problem noted by Ric Anderson of the 22471345Sgshapiro University of Arizona. 22571345Sgshapiro Fix LDAP map -m (match only) flag. Problem noted by Jeff Giuliano 22671345Sgshapiro of Collective Technologies. 22771345Sgshapiro Avoid using a negative argument for sleep() calls when delaying answers 22871345Sgshapiro to EXPN/VRFY commands on systems which respond very slowly. 22971345Sgshapiro Problem noted by Mikolaj J. Habryn of Optus Internet 23071345Sgshapiro Engineering. 23171345Sgshapiro Make sure the F=u flag is set in the default prog mailer 23271345Sgshapiro definition. Problem noted by Kari Hurtta of the Finnish 23371345Sgshapiro Meteorological Institute. 23471345Sgshapiro Fix IPv6 check for unspecified addresses. Patch from 23571345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 23671345Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 23771345Sgshapiro Meteorological Institute. 23871345Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 23971345Sgshapiro of the parameters to find Family= setting before trying to 24071345Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 24171345Sgshapiro Kletnieks of Virginia Tech. 24271345Sgshapiro When delivering to a file directly from an alias, do not call 24371345Sgshapiro initgroups(); instead use the DefaultUser group information. 24471345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 24571345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 24671345Sgshapiro created. Otherwise, sendmail can not remove it upon 24771345Sgshapiro close. Problem noted by Werner Wiethege. 24871345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 24971345Sgshapiro overall connections, not the number of connections per 25071345Sgshapiro socket. A future version may change this to per socket 25171345Sgshapiro counting. 25271345Sgshapiro Portability: 25371345Sgshapiro Clean up libsmdb so it functions properly on platforms 25471345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t). Problem 25571345Sgshapiro noted by Rein Tollevik of Basefarm AS. 25671345Sgshapiro Fix man page formatting for compatibility with Solaris' 25771345Sgshapiro whatis. From Stephen Gildea of InTouch Systems, Inc. 25871345Sgshapiro UnixWare 7 includes snprintf() support. From Larry 25971345Sgshapiro Rosenman. 26071345Sgshapiro IPv6 changes for platforms using KAME.

Problem noted by Bob Hughes 26471345Sgshapiro of Pacific Access. 26571345Sgshapiro Add preliminary support for AIX 5. Contributed by 26671345Sgshapiro Valdis Kletnieks of Virginia Tech. 26771345Sgshapiro Solaris 9 load average support from Andrew Tucker of Sun 26871345Sgshapiro Microsystems. 26971345Sgshapiro CONFIG: Reject addresses of the form a!b if FEATURE(`nouucp', `r') 27071345Sgshapiro is used. Problem noted by Phil Homewood of Asia Online, 27171345Sgshapiro patch from Neil Rickert of Northern Illinois University. 27271345Sgshapiro CONFIG: Change the default DNS based blacklist server for 27373188Sgshapiro FEATURE(`dnsbl') to blackholes.mail-abuse.org. 27471345Sgshapiro CONFIG: Deal correctly with the 'C' flag in {daemon_flags}, i.e., 27571345Sgshapiro implicitly assume canonical host names. 27671345Sgshapiro CONFIG: Deal with "::" in IPv6 addresses for access_db. Based on 27771345Sgshapiro patch by Motonori Nakamura of Kyoto University. 27871345Sgshapiro CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of 27971345Sgshapiro Virginia Tech. 28071345Sgshapiro CONFIG: Pass the illegal header form <list:;> through untouched 28171345Sgshapiro instead of making it worse. Problem noted by Motonori 28271345Sgshapiro Nakamura of Kyoto University. 28371345Sgshapiro CONTRIB: Added buildvirtuser (see `perldoc contrib/buildvirtuser`). 28471345Sgshapiro CONTRIB: qtool.pl: An empty queue is not an error. Problem noted 28571345Sgshapiro by Jan Krueger of digitalanswers communications consulting 28671345Sgshapiro gmbh. 28771345Sgshapiro CONTRIB: domainmap.m4: Handle domains with '-' in them. From Mark 28871345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 28971345Sgshapiro DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4 29071345Sgshapiro variables into bldOS, bldREL, and bldARCH to prevent 29173188Sgshapiro namespace collisions. Problem noted by Motonori Nakamura 29271345Sgshapiro of Kyoto University. 29371345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 29471345Sgshapiro causes some changes in behavior and may break rmail for 29571345Sgshapiro installations where sendmail is actually a wrapper to 29671345Sgshapiro another MTA. The change will re-appear in a future 29771345Sgshapiro version. 29871345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 29971345Sgshapiro and SunOS 5.8. Requested by Jeff A. Earickson of Colby 30071345Sgshapiro College and John Beck of Sun Microsystems. 30171345Sgshapiro VACATION: Fix pattern matching for addresses to ignore. 30271345Sgshapiro VACATION: Don't reply to addresses of the form owner-* 30371345Sgshapiro or *-owner. 30471345Sgshapiro New Files: 30571345Sgshapiro cf/ostype/aix5.m4 30671345Sgshapiro contrib/buildvirtuser 30771345Sgshapiro devtools/OS/AIX.5.0 30871345Sgshapiro 30966494Sgshapiro8.11.1/8.11.1 2000/09/27 31066494Sgshapiro Fix SMTP EXPN command output if the address expands to a single 31166494Sgshapiro name. Fix from John Beck of Sun Microsystems. 31266494Sgshapiro Don't try STARTTLS in the client if the PRNG has not been properly 31366494Sgshapiro seeded. This problem only occurs on systems without 31466494Sgshapiro /dev/urandom. Problem detected by Jan Krueger of 31566494Sgshapiro digitalanswers communications consulting gmbh and 31666494Sgshapiro Neil Rickert of Northern Illinois University. 31766494Sgshapiro Don't use the . and .. directories when expanding QueueDirectory 31866494Sgshapiro wildcards. 31966494Sgshapiro Do not try to cache LDAP connections across processes as a parent 32066494Sgshapiro process may close the connection before the child process 32166494Sgshapiro has completed.

If sendmail needs to drop 42364562Sgshapiro these privileges and the operating system doesn't set the 42464562Sgshapiro saved-uid as well, exit with an error. Problem noted by 42564562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 42664562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 42764562Sgshapiro it populates. It is possible that some broken 42864562Sgshapiro implementations of snprintf() exist that do not do this. 42964562Sgshapiro Systems in this category should compile with 43064562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 43164562Sgshapiro system and report broken implementations to 43264562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 43364562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 43464562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 43564562Sgshapiro Implementation influenced by the example programs of 43664562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 43764562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 43864562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 43964562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 44064562Sgshapiro cf/README and doc/op/op.*. 44164562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 44264562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 44364562Sgshapiro ${server_name}, and ${server_addr}. These are documented 44464562Sgshapiro in cf/README and doc/op/op.*. 44564562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 44664562Sgshapiro random data. 44764562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 44864562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 44964562Sgshapiro try to use STARTTLS despite the security problems. 45064562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 45164562Sgshapiro support encryption. Based on code contributed by Tim 45264562Sgshapiro Martin of CMU. 45364562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 45464562Sgshapiro strength factor. 45564562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 45664562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 45764562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 45864562Sgshapiro of CMU. 45964562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 46064562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 46164562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 46264562Sgshapiro Fix the default family selection for DaemonPortOptions. As 46364562Sgshapiro documented, unless a family is specified in a 46464562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 46564562Sgshapiro also the default if no DaemonPortOptions value is set. 46664562Sgshapiro Therefore, IPv6 users should configure additional sockets 46764562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 46864562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 46964562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 47064562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 47164562Sgshapiro the interface information for an outgoing connection. 47264562Sgshapiro Not doing so was creating a mismatch between the socket 47364562Sgshapiro family and address used in subsequent connections if the 47464562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 47564562Sgshapiro by John Beck of Sun Microsystems. 47664562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 47764562Sgshapiro family based on the IP address. ${if_family} is no longer 47864562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 47964562Sgshapiro of Sun Microsystems. 48064562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 48164562Sgshapiro macros for both the incoming interface address/family and 48264562Sgshapiro the outgoing interface address/family. In order for M=b 48364562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 48464562Sgshapiro the incoming information in the queue file for later 48564562Sgshapiro delivery attempts. 48664562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 48764562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 48864562Sgshapiro smoe.org. 48964562Sgshapiro Add more vigilance in checking for putc() errors on output streams 49064562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 49164562Sgshapiro noted by Graeme Hewson of Oracle. 49264562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 49364562Sgshapiro Problem noted by Ajay Matia. 49464562Sgshapiro Under certain circumstances, an address could be listed as deferred 49564562Sgshapiro but would be bounced back to the sender as failed to be 49664562Sgshapiro delivered when it really should have been queued.

Problem 50664562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 50764562Sgshapiro Convert the free disk space shown in a control socket status query 50864562Sgshapiro to kilobyte units. 50964562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 51064562Sgshapiro looking up the hostname, requeue the message for a later 51164562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 51264562Sgshapiro Polytechnic. 51364562Sgshapiro Under the proper circumstances, failed connections would be recorded 51464562Sgshapiro as "Bad file number" instead of "Connection failed" in the 51564562Sgshapiro queue file and persistent host status. Problem noted by 51664562Sgshapiro Graeme Hewson of Oracle. 51764562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 51864562Sgshapiro within the hoststatus directory (e.g., lost+found). 51964562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 52064562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 52164562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 52264562Sgshapiro If a message data file can't be opened at delivery time, panic and 52364562Sgshapiro abort the attempt instead of delivering a message that 52464562Sgshapiro states "<<< No Message Collected >>>". 52564562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 52664562Sgshapiro restrictive.

This option and 79964562Sgshapiro its use is deprecated and will be removed from a future 80064562Sgshapiro version of sendmail. 80164562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 80264562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 80364562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 80464562Sgshapiro (IdS). 80564562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 80664562Sgshapiro a large number of files. See cf/README for more details. 80764562Sgshapiro The directory structure of the distribution has changed slightly 80864562Sgshapiro for easier code sharing among the programs. 80964562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 81064562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 81164562Sgshapiro which hold the client's authentication credentials, 81264562Sgshapiro the mechanism used for authentication, and the 81364562Sgshapiro authorization identity (i.e., the AUTH= parameter if 81464562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 81564562Sgshapiro On systems which use the Torek stdio library (all of the BSD 81664562Sgshapiro distributions), use memory-buffered files to reduce 81764562Sgshapiro file system overhead by not creating temporary files on 81864562Sgshapiro disk. Contributed by Exactis.com, Inc. 81964562Sgshapiro New option DataFileBufferSize to control the maximum size of a 82064562Sgshapiro memory-buffered data (df) file before a disk-based file is 82164562Sgshapiro used. Contributed by Exactis.com, Inc. 82264562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 82364562Sgshapiro memory-buffered transcript (xf) file before a disk-based 82464562Sgshapiro file is used. Contributed by Exactis.com, Inc. 82564562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 82664562Sgshapiro now listen on several different ports. Use: 82764562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 82864562Sgshapiro to run a Message Submission Agent (MSA); this is turned 82964562Sgshapiro on by default in m4-generated .cf files; it can be turned 83064562Sgshapiro off with FEATURE(`no_default_msa'). 83164562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 83264562Sgshapiro begin using RFC 2476 Message Submission for initial user 83364562Sgshapiro message submission. XUSR may disappear from a future release. 83464562Sgshapiro The new '-G' (relay (gateway) submission) command line option 83564562Sgshapiro indicates that the message being submitted from the command 83664562Sgshapiro line is for relaying, not initial submission. This means 83764562Sgshapiro the message will be rejected if the addresses are not fully 83864562Sgshapiro qualified and no canonicalization will be done. Future 83964562Sgshapiro releases may even reject improperly formed messages. 84064562Sgshapiro The '-U' (initial user submission) command line option is 84164562Sgshapiro deprecated and may be removed from a future release. 84264562Sgshapiro Mail user agents should begin using '-G' to indicate that 84364562Sgshapiro this is a relay submission (the inverse of -U). 84464562Sgshapiro The next release of sendmail will assume that any message submitted 84564562Sgshapiro from the command line is an initial user submission and act 84664562Sgshapiro accordingly. 84764562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 84864562Sgshapiro program or deliver to file as the owner of that file, the 84964562Sgshapiro address is marked as unsafe. This means if RunAsUser is 85064562Sgshapiro set, users won't be able to use programs or delivery to 85164562Sgshapiro files in their .forward files. Administrators can override 85264562Sgshapiro this by setting the DontBlameSendmail option to the new 85364562Sgshapiro setting NonRootSafeAddr. 85464562Sgshapiro Allow group or world writable directories if the sticky bit is set 85564562Sgshapiro on the directory and DontBlameSendmail is set to 85664562Sgshapiro TrustStickyBit.

To use multiple queues, supply 88964562Sgshapiro a QueueDirectory option value ending with an asterisk. For 89064562Sgshapiro example, /var/spool/mqueue/q* will use all of the 89164562Sgshapiro directories or symbolic links to directories beginning with 89264562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 89364562Sgshapiro mind, the queue directory structure should not be changed 89464562Sgshapiro while sendmail is running. Queue runs create a separate 89564562Sgshapiro process for running each queue unless the verbose flag is 89664562Sgshapiro given on a non-daemon queue run. New items are randomly 89764562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 89864562Sgshapiro Support different directories for qf, df, and xf queue files; if 89964562Sgshapiro subdirectories or symbolic links to directories of those names 90064562Sgshapiro exist in the queue directories, they are used for the 90164562Sgshapiro corresponding queue files. Keep in mind, the queue 90264562Sgshapiro directory structure should not be changed while sendmail is 90364562Sgshapiro running. Proposed by Mathias Koerber of Singapore 90464562Sgshapiro Telecommunications Ltd. 90564562Sgshapiro New queue file naming system which uses a filename guaranteed to be 90664562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 90764562Sgshapiro without fancy file system locking. Queued items can be 90864562Sgshapiro moved between queues easily.

Contributed by Exactis.com, Inc. 91564562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 91664562Sgshapiro avoids opening and reading each queue file when preparing 91764562Sgshapiro to run the queue.

This can be used with LMTP 93364562Sgshapiro local delivery agents which listen on a named socket. An 93464562Sgshapiro example mailer might be: 93564562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 93664562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 93764562Sgshapiro A=FILE /var/run/lmtpd 93864562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 93964562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 94064562Sgshapiro instead. 94164562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 94264562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 94364562Sgshapiro connections), IPC (which will be deprecated in a future 94464562Sgshapiro version), and FILE (for UNIX domain socket delivery). 94564562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 94664562Sgshapiro flags. 94764562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 94864562Sgshapiro body of the original message on delivery status 94964562Sgshapiro notifications. 95064562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 95164562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 95264562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 95364562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 95464562Sgshapiro Steve Schweinhart of America Online. 95564562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 95664562Sgshapiro not be set after rulesets are defined. Suggested by 95764562Sgshapiro Mitchell Blank Jr of Exec-PC. 95864562Sgshapiro Do not report temporary failure on delivery to files. In 95964562Sgshapiro interactive delivery mode, this would result in two SMTP 96064562Sgshapiro responses after the DATA command. Problem noted by 96164562Sgshapiro Nik Conwell of Boston University. 96264562Sgshapiro Check file close when mailing to files. Problem noted by Nik 96364562Sgshapiro Conwell of Boston University. 96464562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 96564562Sgshapiro Curtis W. Hillegas of Princeton University. 96664562Sgshapiro Always bind to the LDAP server regardless of whether you are using 96764562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 96864562Sgshapiro @Home Network. 96964562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 97064562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 97164562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 97264562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 97364562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 97464562Sgshapiro similar to check_rcpt etc. 97564562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 97664562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 97764562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 97864562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 97964562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 98064562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 98164562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 98264562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 98364562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 98464562Sgshapiro the corresponding DSN parameter values. Proposed by 98564562Sgshapiro Mathias Herberts. 98664562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 98764562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 98864562Sgshapiro before the message has been collected, thereafter it holds 98964562Sgshapiro the message size as computed by sendmail (and can be used 99064562Sgshapiro in check_compat). 99164562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 99264562Sgshapiro sendmail is using instead of the value of the DeliveryMode 99364562Sgshapiro option. 99464562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 99564562Sgshapiro Drop explicit From: if same as what would be generated only if it is 99664562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 99764562Sgshapiro Write pid to file also if sendmail only processes the queue. 99864562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 99964562Sgshapiro Log "low on disk space" only when necessary. 100064562Sgshapiro New macro ${load_avg} can be used to check the current load average. 100164562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 100264562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 100364562Sgshapiro is set. 100464562Sgshapiro Flag -S for maps to specify the character which is substituted 100564562Sgshapiro for spaces (instead of the default given by O BlankSub). 100664562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 100764562Sgshapiro This flag is set by default for the host map. Based on a 100864562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 100964562Sgshapiro Open maps only on demand, not at startup. 101064562Sgshapiro Log warning about unsupported IP address families. 101164562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 101264562Sgshapiro of the sum of all headers. This can be used to prevent 101364562Sgshapiro a denial-of-service attack. 101464562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 101564562Sgshapiro headers and parameters within those headers. This option 101664562Sgshapiro is intended to protect mail user agents from buffer 101764562Sgshapiro overflow attacks. 101864562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 101964562Sgshapiro alias recursion. 102064562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 102164562Sgshapiro Map type syslog to log the key via syslogd. 102264562Sgshapiro Entries in the alias file can be continued by putting a backslash 102364562Sgshapiro directly before the newline. 102464562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 102564562Sgshapiro dead.letter file, formerly hardcoded to 102664562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 102764562Sgshapiro default), sendmail will not attempt to save to a 102864562Sgshapiro system-wide dead.letter file if it can not bounce the mail 102964562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 103064562Sgshapiro file as it has in the past when the dead.letter file 103164562Sgshapiro could not be opened. 103264562Sgshapiro New option PidFile to define the location of the pid file. The 103364562Sgshapiro value of this option is macro expanded. 103464562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 103564562Sgshapiro process title shown in 'ps' listings. 103664562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 103764562Sgshapiro (along with the already existing macros): 103864562Sgshapiro ${daemon_info} Daemon information, e.g. 103964562Sgshapiro SMTP+queueing@00:30:00 104064562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 104164562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 104264562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 104364562Sgshapiro ${daemon_port} Daemon port, e.g., 25 104464562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 104564562Sgshapiro New macros especially for virtual hosting: 104664562Sgshapiro ${if_name} hostname of interface of incoming connection. 104764562Sgshapiro ${if_addr} address of interface of incoming connection. 104864562Sgshapiro The latter is only set if the interface does not belong to the 104964562Sgshapiro loopback net. 105064562Sgshapiro If a message being accepted via a method other than SMTP and 105164562Sgshapiro would be rejected by a header check, do not send the message. 105264562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 105364562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 105464562Sgshapiro Provide header value as quoted string in the macro 105564562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 105664562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 105764562Sgshapiro The length of the header value is stored in ${hdrlen}. 105864562Sgshapiro H*: allows to specify a default ruleset for header checks. This 105964562Sgshapiro ruleset will only be called if the individual header does 106064562Sgshapiro not have its own ruleset assigned. Suggested by Jan 106164562Sgshapiro Krueger of Unix-AG of University of Hannover. 106264562Sgshapiro The name of the header field stored in ${hdr_name}. 106364562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 106464562Sgshapiro removed if the config file version is greater than or equal 106564562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 106664562Sgshapiro input "token (1)" but does not match "token". 106764562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 106864562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 106964562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 107064562Sgshapiro Ericsson. 107164562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 107264562Sgshapiro messages with 8-bit text in headers. Problem noted by 107364562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 107464562Sgshapiro of Ericsson. 107564562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 107664562Sgshapiro modified database map file. Problem noted by Chris Adams 107764562Sgshapiro of Renaissance Internet Services. 107864562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 107964562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 108064562Sgshapiro queue up the message instead of bouncing it. 108164562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 108264562Sgshapiro standard does not provide any indication of what to do when 108364562Sgshapiro something other than 250 is received. Based on a patch 108464562Sgshapiro from Steve Schweinhart of America Online. 108564562Sgshapiro New option TrustedUser allows to specify a user who can own 108664562Sgshapiro important files instead of root. This requires HASFCHOWN. 108764562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 108864562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 108964562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 109064562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 109164562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 109264562Sgshapiro $? tests also whether the macro is non-null. 109364562Sgshapiro Print an error message if a mailer definition contains an invalid 109464562Sgshapiro equate name. 109564562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 109664562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 109764562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 109864562Sgshapiro mailer to return after sending all data to it. 109964562Sgshapiro Only free memory from the process list when adding a new process 110064562Sgshapiro into a previously filled slot. Previously, the memory was 110164562Sgshapiro freed at removal time. Since removal can happen in a 110264562Sgshapiro signal handler, this may leave the memory map in an 110364562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 110464562Sgshapiro David Cooley of Colby College. 110564562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 110664562Sgshapiro local users in the passwd file. The UserDB code has 110764562Sgshapiro already decided the message will be passed to another host 110864562Sgshapiro for processing. Fix from Tony Landells of Burdett 110964562Sgshapiro Buckeridge Young Limited. 111064562Sgshapiro Support LDAP authorization via either a file containing the 111164562Sgshapiro password or Kerberos V4 using the new map options 111264562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 111364562Sgshapiro distinguished_name is who to login as. The method can be 111464562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 111564562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 111664562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 111764562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 111864562Sgshapiro of Stanford University. 111964562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 112064562Sgshapiro deprecated and will be removed in a future version. 112164562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 112264562Sgshapiro and the map has the column delimiter set, it turns that 112364562Sgshapiro response into a delimiter separated string. The LDAP map 112464562Sgshapiro will traverse multiple entries as well. LDAP alias maps 112564562Sgshapiro automatically set the column delimiter to the comma. 112664562Sgshapiro Based on patch from Booker Bense of Stanford University and 112764562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 112864562Sgshapiro Support return of multiple values for a single LDAP lookup. The 112964562Sgshapiro values to be returned should be in a comma separated string. 113064562Sgshapiro For example, `-v "email,emailother"'. Patch from 113164562Sgshapiro Curtis W. Hillegas of Princeton University. 113264562Sgshapiro Allow the use of LDAP for alias maps. 113364562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 113464562Sgshapiro attributes found in the match will be returned. 113564562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 113664562Sgshapiro breaking up a single entry into multiple entries. This is 113764562Sgshapiro needed for LDAP alias file specifications to allow for 113864562Sgshapiro comma separated key and value strings. 113964562Sgshapiro Keep connections to LDAP server open instead of opening and closing 114064562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 114164562Sgshapiro connections such that multiple maps which use the same 114264562Sgshapiro host, port, bind DN, and authentication will only result in 114364562Sgshapiro a single connection to that host. 114464562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 114564562Sgshapiro Be more careful about checking for errors and freeing memory on 114664562Sgshapiro LDAP lookups. 114764562Sgshapiro Use asynchronous LDAP searches to save memory and network 114864562Sgshapiro resources. 114964562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 115064562Sgshapiro Increase portability to the Netscape LDAP libraries. 115164562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 115264562Sgshapiro replaced with the literal contents of the map lookup key -- 115364562Sgshapiro note that this means a lookup can be done using the LDAP 115464562Sgshapiro special characters. The new '%0' token can be used instead 115564562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 115664562Sgshapiro For example, if the LDAP map specification contains '-k 115764562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 115864562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 115964562Sgshapiro user attribute. Instead, if the LDAP map specification 116064562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 116164562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 116264562Sgshapiro with the name "*". 116364562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 116464562Sgshapiro more than one is returned, it is equivalent to no records 116564562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 116664562Sgshapiro alias dereference option; "-Z size" limits the number of 116764562Sgshapiro matches to return. 116864562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 116964562Sgshapiro LDAP maps. The value should only contain LDAP specific 117064562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 117164562Sgshapiro settings will be used for all LDAP maps unless they are 117264562Sgshapiro specified in the individual map specification ('K' 117364562Sgshapiro command). This option should be set before any LDAP maps 117464562Sgshapiro are defined. 117564562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 117664562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 117764562Sgshapiro Tech. 117864562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 117964562Sgshapiro particular, class entries get much smaller, which can be 118064562Sgshapiro important if you have large classes. 118164562Sgshapiro On network-related temporary failures, record the hostname which 118264562Sgshapiro gave error in the queued status message. Requested by 118364562Sgshapiro Ulrich Windl of the Universitat Regensburg. 118464562Sgshapiro Add new F=% mailer flag to allow for a store and forward 118564562Sgshapiro configuration. Mailers which have this flag will not attempt 118671345Sgshapiro delivery on initial receipt of a message or on queue runs 118764562Sgshapiro unless the queued message is selected using one of the 118864562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 118964562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 119064562Sgshapiro New option ControlSocketName which, when set, creates a daemon 119164562Sgshapiro control socket. This socket allows an external program to 119264562Sgshapiro control and query status from the running sendmail daemon 119364562Sgshapiro via a named socket, similar to the ctlinnd interface to the 119464562Sgshapiro INN news server. Access to this interface is controlled by 119564562Sgshapiro the UNIX file permissions on the named socket on most UNIX 119664562Sgshapiro systems (see sendmail/README for more information). An 119764562Sgshapiro example control program is provided as contrib/smcontrol.pl. 119864562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 119964562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 120064562Sgshapiro number of processors online on the system (if that can be 120164562Sgshapiro determined). For single processor machines, this change 120264562Sgshapiro has no effect. 120364562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 120464562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 120564562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 120664562Sgshapiro Motonori Nakamura of Kyoto University. 120764562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 120864562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 120964562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 121064562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 121164562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 121264562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 121364562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 121464562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 121564562Sgshapiro connection-based denial of service attacks. 121664562Sgshapiro Log basic information about authenticated connections at LogLevel 121764562Sgshapiro 10 or higher. 121864562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 121964562Sgshapiro information (from= syslog line). 122064562Sgshapiro Log the DSN code for each recipient if one is available as a new 122164562Sgshapiro equate (dsn=). 122264562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 122364562Sgshapiro New "ph" map for performing ph queries in rulesets.

Problem noted by Kari Hurtta of the 122964562Sgshapiro Finnish Meteorological Institute. 123064562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 123164562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 123264562Sgshapiro When a forward file points to an alias which runs a program, run 123364562Sgshapiro the program as the default user and the default group, not 123464562Sgshapiro the forward file user. This change also assures the 123564562Sgshapiro :include: directives in aliases are also processed using 123664562Sgshapiro the default user and group. Problem noted by Sergiu 123764562Sgshapiro Popovici of DNT Romania. 123864562Sgshapiro Prevent attempts to save a dead.letter file for a user with 123964562Sgshapiro no home directory (/no/such/directory). Problem noted by 124064562Sgshapiro Michael Brown of Finnigan FT/MS. 124164562Sgshapiro Include message delay and number of tries when logging that a 124264562Sgshapiro message has been completely delivered (LogLevel of 10 or 124364562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 124464562Sgshapiro Log the sender of a message even if none of the recipients were 124564562Sgshapiro accepted. If some of the recipients were rejected, it is 124664562Sgshapiro helpful to know the sender of the message. 124764562Sgshapiro Check the root directory (/) when checking a path for safety. 124864562Sgshapiro Problem noted by John Beck of Sun Microsystems. 124964562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 125064562Sgshapiro interactive and delivering to an alias which resolves to 125164562Sgshapiro multiple files. 125264562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 125364562Sgshapiro greater (see below); the help function doesn't print the 125464562Sgshapiro version of sendmail any longer, instead it is placed in 125564562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 125664562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 125764562Sgshapiro skipped and a version line (#vers) is introduced. The 125864562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 125964562Sgshapiro version is found, a warning is logged. The '#vers' 126064562Sgshapiro directive should be placed at the top of the help file. 126164562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 126264562Sgshapiro disk succeeded. Suggested by Nick Christenson. 126364562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 126464562Sgshapiro length before the attempt. 126564562Sgshapiro If a forward points to a filename for delivery, change to the 126664562Sgshapiro user's uid before checking permissions on the file. This 126764562Sgshapiro allows delivery to files on NFS mounted directories where 126864562Sgshapiro root is remapped to nobody. Problem noted by Harald 126964562Sgshapiro Daeubler of Universitaet Ulm. 127064562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 127164562Sgshapiro host status files, not all files. 127264562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 127364562Sgshapiro in the queue file for the message and set when delivery 127464562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 127564562Sgshapiro Wonderworks Inc. 127664562Sgshapiro Add support for storing information between rulesets using the new 127764562Sgshapiro macro map class. This can be used to store information 127864562Sgshapiro between queue runs as well using $={persistentMacros}. 127964562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 128064562Sgshapiro of Hannover. 128164562Sgshapiro New map class arith to allow for computations in rules. The 128264562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 128364562Sgshapiro as key. The two operands are specified as arguments; the 128464562Sgshapiro lookup returns the result of the computation. For example, 128564562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 128664562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 128764562Sgshapiro Add new syntax for header declarations which decide whether to 128864562Sgshapiro include the header based on a macro rather than a mailer 128964562Sgshapiro flag: 129064562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 129164562Sgshapiro This should be used along with $={persistentMacros}. 129264562Sgshapiro It can be used for adding headers to a message based on 129364562Sgshapiro the results of check_* and header check rulesets. 129464562Sgshapiro Allow new named config file rule check_eoh which is called after 129564562Sgshapiro all of the headers have been collected. The input to the 129664562Sgshapiro ruleset the number of headers and the size of all of the 129764562Sgshapiro headers in bytes separated by $|. This ruleset along with 129864562Sgshapiro the macro storage map can be used to correlate information 129964562Sgshapiro gathered between headers and to check for missing headers. 130064562Sgshapiro See cf/README or doc/op/op.ps for an example. 130164562Sgshapiro Change the default for the MeToo option to True to correspond 130264562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 130364562Sgshapiro option is deprecated and will be removed from a future 130464562Sgshapiro version. 130564562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 130664562Sgshapiro Change the sendmail binary default for SuperSafe to True. 130764562Sgshapiro Display ruleset names in debug and address test mode output 130864562Sgshapiro if referencing a named ruleset. 130964562Sgshapiro New mailer equate m= which will limit the number of messages 131064562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 131164562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 131264562Sgshapiro using it to sort. Now all the same domains are really run 131364562Sgshapiro through the queue together. If they have the same MX host, 131464562Sgshapiro then they will have a much better opportunity to use the 131564562Sgshapiro connection cache if available. This should be a reasonable 131664562Sgshapiro performance improvement. Patch from Randall Winchester of 131764562Sgshapiro the University of Maryland. 131864562Sgshapiro If a message is rejected by a header check ruleset, log who would 131964562Sgshapiro have received the message if it had not been rejected. 132064562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 132164562Sgshapiro queue immediately. No delivery attempt is made. 132264562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 132364562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 132464562Sgshapiro COMMANDS). 132564562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 132664562Sgshapiro but for outgoing connections. 132764562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 132864562Sgshapiro error messages and logging) and Modifiers, i.e. 132964562Sgshapiro a require authentication 133064562Sgshapiro b bind to interface through which mail has 133164562Sgshapiro been received 133264562Sgshapiro c perform hostname canonification 133364562Sgshapiro f require fully qualified hostname 133464562Sgshapiro h use name of interface for outgoing HELO 133564562Sgshapiro command 133664562Sgshapiro C don't perform hostname canonification 133764562Sgshapiro E disallow ETRN (see RFC 2476) 133864562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 133964562Sgshapiro h use name of interface for HELO command 134064562Sgshapiro The version number for queue files (qf) has been incremented to 4. 134164562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 134264562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 134364562Sgshapiro Institutes of Health. 134464562Sgshapiro If a mailer dies, print the status in decimal instead of octal 134564562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 134664562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 134764562Sgshapiro Move message priority from sender to recipient logging. Suggested by 134864562Sgshapiro Ulrich Windl of the Universitat Regensburg. 134964562Sgshapiro Add support for Berkeley DB 3.X. 135064562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 135164562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 135264562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 135364562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 135464562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 135564562Sgshapiro sub-options is set on the command line. Problem noted by 135664562Sgshapiro Graeme Hewson of Oracle. 135764562Sgshapiro Randomize equal preference MX records each time delivery is 135864562Sgshapiro attempted via a new connection to a host instead of once per 135964562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 136064562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 136164562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 136264562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 136364562Sgshapiro to hosts which have dynamically assigned names. 136464562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 136564562Sgshapiro the bounce for the same reason. If the body is not 8-bit 136664562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 136764562Sgshapiro not be included in the bounce. Problem noted by Valdis 136864562Sgshapiro Kletnieks of Virginia Tech. 136964562Sgshapiro The timeout for sending a message via SMTP has been changed from 137064562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 137164562Sgshapiro simply checks for progress on sending data every 5 minutes. 137264562Sgshapiro This will detect the inability to send information quicker 137364562Sgshapiro and reduce the number of processes simply waiting to 137464562Sgshapiro timeout. 137564562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 137664562Sgshapiro interface address structure when loading the system network 137764562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 137864562Sgshapiro Nanoteq. 137964562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 138064562Sgshapiro indicates the number of interfaces to read when probing 138164562Sgshapiro for hostnames and IP addresses for class w ($=w). The 138264562Sgshapiro default value is 512.

Prindeville of Enteka Enterprise Technology 173964562Sgshapiro Services. 174064562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 174164562Sgshapiro names. Problem noted by Randall Winchester of Swales 174264562Sgshapiro Aerospace. 174364562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 174464562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 174564562Sgshapiro University and Brian Candler. 174664562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 174764562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 174864562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 174964562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 175064562Sgshapiro Institute. 175164562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 175264562Sgshapiro i.e., to set, add, or delete flags. 175364562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 175464562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 175564562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 175664562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 175764562Sgshapiro after check_rcpt and allows for exceptions from the checks. 175864562Sgshapiro CONFIG: Map declarations have been moved into their associated 175964562Sgshapiro feature files to allow greater flexibility in use of 176064562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 176164562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 176264562Sgshapiro line string for the local mailer. Requested by Il Oh of 176364562Sgshapiro Willamette Industries, Inc. 176464562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 176564562Sgshapiro converted to <user@d> 176664562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 176764562Sgshapiro Sun's older, broken configuration files. 176864562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 176964562Sgshapiro normal configuration, allowing anti-spam checks to be 177064562Sgshapiro performed. 177164562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 177264562Sgshapiro ${client_name} can't be resolved just temporarily. 177364562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 177464562Sgshapiro Institute. 177564562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 177664562Sgshapiro be accessed by their numbers). 177764562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 177864562Sgshapiro which describes whether to disallow "!" in the local part 177964562Sgshapiro of an address. 178064562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 178164562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 178264562Sgshapiro set. If the ruleset returns a mailer, the appropriate 178364562Sgshapiro action is taken, otherwise the returned tokens are ignored. 178464562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 178564562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 178664562Sgshapiro The latter is kept around for backward compatibility. 178764562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 178864562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 178964562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 179064562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 179164562Sgshapiro line.

Problem noted by Ezequiel H. Panepucci of 181664562Sgshapiro Yale University. 181764562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 181864562Sgshapiro be used for building. 181964562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 182064562Sgshapiro used for a fresh build. 182164562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 182264562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 182364562Sgshapiro ranlib. 182464562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 182564562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 182664562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 182764562Sgshapiro building of the man pages when defined. Suggested by Bryan 182864562Sgshapiro Costales. 182964562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 183064562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 183164562Sgshapiro installation of the sendmail helpfile and statistics file 183264562Sgshapiro respectively. Suggested by Bryan Costales. 183364562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 183464562Sgshapiro of Siemens Business Services. 183564562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 183664562Sgshapiro stdio library. The new buffered file I/O depends on the 183764562Sgshapiro Torek stdio library. This option can be either portable or 183864562Sgshapiro torek. 183964562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 184064562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 184164562Sgshapiro They should contain the C source files for the object files 184264562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 184364562Sgshapiro will be passed to the 'make depend' stage of compilation. 184464562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 184564562Sgshapiro in the sendmail distribution. Each has the form 184664562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 184764562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 184864562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 184964562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 185064562Sgshapiro building the distribution, but documentation on the changes 185164562Sgshapiro are in devtools/README. 185264562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 185364562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 185464562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 185564562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 185664562Sgshapiro new variable which identifies the root of the source 185764562Sgshapiro directories for all of the programs in the distribution. 185864562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 185964562Sgshapiro time. They can both still be overridden by setting the m4 186064562Sgshapiro macro. 186164562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 186264562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 186364562Sgshapiro build configurations, and places objects in obj.prefix.*/. 186464562Sgshapiro Complains as 'Build -f file' does for existing object 186564562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 186664562Sgshapiro Corporation. 186764562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 186864562Sgshapiro manual pages in the directory tree specified by 186964562Sgshapiro confMANROOTMAN. 187064562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 187164562Sgshapiro preformatted pages from the distribution. The new variable 187264562Sgshapiro confCOPY specifies the copying program. 187364562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 187464562Sgshapiro question. Suggested by Terry Lambert of Whistle 187564562Sgshapiro Communications. 187664562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 187764562Sgshapiro of the installed statistics and help files, respectively. 187864562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 187964562Sgshapiro operating system identity. Problem noted by Erik 188064562Sgshapiro Wachtenheim of Dartmouth College. 188164562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 188264562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 188364562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 188464562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 188564562Sgshapiro how to strip binaries. These are used by the new 188664562Sgshapiro install-strip target. 188764562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 188864562Sgshapiro the others (if it exists). 188964562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 189064562Sgshapiro then the default ones. 189180785Sgshapiro MAIL.LOCAL: Will not be installed set-user-id root. To use mail.local 189264562Sgshapiro as local delivery agent without LMTP mode, use 189364562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 189464562Sgshapiro to set the S flag. 189564562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 189664562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 189764562Sgshapiro Northern Illinois University. 189864562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 189964562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 190064562Sgshapiro the Finnish Meteorological Institute. 190164562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 190264562Sgshapiro MAILLOCK when compiling. Also requires linking with 190364562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 190464562Sgshapiro University. 190564562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 190664562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 190764562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 190864562Sgshapiro University. 190964562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 191064562Sgshapiro structure to the beginning of the program. This ensures that 191164562Sgshapiro the getservbyname() is done before any seteuid to a possibly 191264562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 191364562Sgshapiro on a Solaris system, this avoids syslog messages such as, 191464562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 191564562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 191664562Sgshapiro University. 191764562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 191864562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 191964562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 192064562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 192164562Sgshapiro characters (in LMTP mode), mail.local split the incoming 192264562Sgshapiro line up into 2046-character output lines (excluding the 192364562Sgshapiro newline). If an input line was 2047 characters long 192464562Sgshapiro (excluding CR-LF) and the last character was a '.', 192564562Sgshapiro mail.local saw it as the end of input, transfered it to the 192664562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 192764562Sgshapiro If the message was much longer, both sendmail and 192864562Sgshapiro mail.local would deadlock waiting for each other to read 192964562Sgshapiro what they have written. Problem noted by Peter Jeremy of 193064562Sgshapiro Alcatel Australia Limited. 193164562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 193264562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 193364562Sgshapiro Neil Rickert of Northern Illinois University. 193464562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 193564562Sgshapiro timeout to avoid starvation. 193664562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 193764562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 193864562Sgshapiro Infinite Monkeys & Co. 193964562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J.

Sites 242138032Speter which need the ability to override security can use the 242238032Speter DontBlameSendmail option. See the README file for more 242338032Speter information. 242438032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 242538032Speter if maps or alias files are in world writable directories. 242638032Speter This fixes the change added to 8.8.6 to prevent links in these 242738032Speter world writable directories. 242838032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 242938032Speter it is in a world writable directory. 243038032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 243138032Speter tty it may be able to push bytes back to the senders input. 243238032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 244138032Speter reverts back to the old behavior of using uid 1 and gid 1. 244238032Speter This is a security problem for Linux which has chosen that 244338032Speter uid and gid for user bin instead of daemon. If DefaultUser 244438032Speter is set in the configuration file, that value overrides this 244538032Speter default. 244680785Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-id binaries 244738032Speter interfered with setting an alternate group id for the 244838032Speter RunAsUser option.

Fix from Andreas Luik 248538032Speter of ISA Informationssysteme GmbH. 248638032Speter Tokenize $&x expansions on right hand side of rules. This eliminates 248738032Speter the need to use tricks like $(dequote "" $&{client_name} $) 248838032Speter to cause the ${client_name} macro to be properly tokenized. 248938032Speter Add the MaxRecipientsPerMessage option: this limits the number of 249038032Speter recipients that will be accepted in a single SMTP 249138032Speter transaction. After this number is reached, sendmail 249238032Speter starts returning "452 Too many recipients" to all RCPT 249338032Speter commands. This can be used to limit the number of recipients 249438032Speter per envelope (in particular, to discourage use of the server 249538032Speter for spamming). Note: a better approach is to restrict 249638032Speter relaying entirely. 249738032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 249838032Speter to ldapx map and added timeout for ldap_open call to 249938032Speter avoid hanging sendmail in the event of hung LDAP servers. 250038032Speter Patch from Booker Bense of Stanford University. 250138032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 252438032Speter of Procter & Gamble. 252538032Speter New DontBlameSendmail option. This option allows administrators to 252638032Speter bypass some of sendmail's file security checks at the expense 252738032Speter of system security.

In particular, if you 256338032Speter have lots of virtual interfaces, this option will speed up 256438032Speter startup. However, unless you make other arrangements, mail 256538032Speter sent to those addresses will be bounced. 256638032Speter Automatically create alias databases if they don't exist and 256738032Speter AutoRebuildAliases is set. 256838032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 256938032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 257038032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 257138032Speter When determining the client host name ($&{client_name} macro), do 257238032Speter a forward (A) DNS lookup on the result of the PTR lookup 257338032Speter and compare results. If they differ or if the PTR lookup 257438032Speter fails, &{client_name} will contain the IP address 257564562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 257638032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 257738032Speter (i.e, it is like -ax for the temporary failure case, in 257838032Speter contrast to the success case). 257938032Speter New syntax to do limited checking of header syntax. A config line 258038032Speter of the form: 258138032Speter HHeader: $>Ruleset 258238032Speter causes the indicated Ruleset to be invoked on the Header 258338032Speter when read. This ruleset works like the check_* rulesets -- 258438032Speter that is, it can reject mail on the basis of the contents. 258538032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 258638032Speter from hiding their connection information in Received: 258738032Speter headers. 258838032Speter When SingleThreadDelivery is active, deliveries to locked hosts 258938032Speter are skipped. This will cause the delivering process to 259038032Speter try the next MX host or queue the message if no other MX 259138032Speter hosts are available. Suggested by Alexander Litvin. 259238032Speter The [FILE] mailer type now delivers to the file specified in the 259338032Speter A= equate of the mailer definition instead of $u. It also 259438032Speter obeys all of the F= mailer flags such as the MIME 259538032Speter 7/8 bit conversion flags. This is useful for defining 259638032Speter a mailer which delivers to the same file regardless of the 259764562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 259838032Speter Do not assume the identity of a remote connection is root@localhost 259938032Speter if the remote connection closes the socket before the 260038032Speter remote identity can be queried. 260138032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 260238032Speter Some mailers, including procmail, require that the real 260338032Speter uid is left unchanged by sendmail. Problem noted by Per 260438032Speter Hedeland of Ericsson. 260538032Speter No longer is the src/obj*/Makefile selected from a large list -- it 260638032Speter is now generated using the information in BuildTools/OS/ -- 260738032Speter some of the details are determined dynamically via 260838032Speter BuildTools/bin/configure.sh. 260938032Speter The other programs in the sendmail distribution -- mail.local, 261038032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 261138032Speter the new Build method which creates an operating system 261238032Speter specific Makefile using the information in BuildTools. 261338032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 261438032Speter a failure on one message won't affect future messages to the 261538032Speter same host). This is necessary if the remote host sends 261638032Speter a 451 error if the domain of the sender does not resolve 261738032Speter as is common in anti-spam configurations. Problem noted 261838032Speter by Mitchell Blank Jr of Exec-PC. 261938032Speter New "discard" mailer for check_* rulesets and header checking 262038032Speter rulesets. If one of the above rulesets resolves to the 262138032Speter $#discard mailer, the commands will be accepted but the 262238032Speter message will be completely discarded after it is accepting. 262338032Speter This means that even if only one of the recipients 262438032Speter resolves to the $#discard mailer, none of the recipients 262538032Speter will receive the mail. Suggested by Brian Kantor. 262638032Speter All but the last cloned envelope of a split envelope were queued 262738032Speter instead of being delivered.

Suggested by Scott 264438032Speter Gifford of The Internet Ramp. 264538032Speter Sendmail would get a segmentation fault if a mailer exited with an 264638032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 264738032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 264838032Speter Institute. 264938032Speter Separate snprintf/vsnprintf routines into separate file for use by 265038032Speter mail.local. 265138032Speter Allow multiple map lookups on right hand side, e.g., 265238032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 265338032Speter Christophe Wolfhugel of the Pasteur Institute. 265438032Speter Properly generate success DSN messages if requested for aliases 265538032Speter which have owner- aliases.

Patch from 273138032Speter Robert Harker of Harker Systems. 273238032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 273338032Speter directory for certain programs. 273438032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 273538032Speter local mail delivery. By the default, /usr/libexec/mail.local 273638032Speter is used. This is expected to be the mail.local shipped 273738032Speter with 8.9 which is LMTP capable. The path is based on the 273838032Speter new confEBINDIR m4 variable. 273938032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 274038032Speter FEATURE(smrsh). Note that this changes the default from 274138032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 274238032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 274338032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 274438032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 274538032Speter the user to setup different .forward files for 274638032Speter user+detail addressing. 274738032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 274838032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 274938032Speter DontProbeInterfaces, and DontBlameSendmail options. 275038032Speter CONFIG: by default do not allow relaying (that is, accepting mail 275138032Speter from outside your domain and sending it to another host 275238032Speter outside your domain). 275338032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 275438032Speter any site to any site. 275538032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 275638032Speter domain as defined by the 'm' class ($=m) to relay. 275738032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 275838032Speter the MX records of the host portion of an incoming recipient. 275938032Speter CONFIG: new FEATURE(access_db) which turns on the access database 276077349Sgshapiro feature. This database gives you the ability to allow 276138032Speter or refuse to accept mail from specified domains for 276238032Speter administrative reasons. By default, names that are listed 276338032Speter as "OK" in the access db are domain names, not host names. 276438032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 276538032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 276638032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 276738032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 276838032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 276938032Speter of FEATURE(access_db) and class 'R' to lookup individual 277038032Speter host names only. 277138032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 277238032Speter using % addressing is used, e.g. user%site@othersite, 277338032Speter and othersite is in class 'R', the check_rcpt ruleset 277438032Speter will strip @othersite and recheck user@site for relaying. 277538032Speter This feature changes that behavior. It should not be 277638032Speter needed for most installations. 277738032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 277838032Speter domain portion of the mail sender is a local host. This 277938032Speter should only be used if absolutely necessary as it opens 278038032Speter a window for spammers. Patch from Randall S. Winchester of 278138032Speter the University of Maryland. 278238032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 278338032Speter block incoming mail destined for certain recipient 278438032Speter usernames, hostnames, or addresses. 278538032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 278638032Speter refused if the host part of the argument to MAIL FROM: cannot 278738032Speter be located in the host name service (e.g., DNS). 278838032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 278938032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 279038032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 279138032Speter MAIL FROM: senders which do not include a domain. 279238032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 279338032Speter Realtime Blackhole List. You can specify the RBL name 279438032Speter server to contact by specifying it as an optional argument. 279538032Speter The default is rbl.maps.vix.com. For details, see 279638032Speter http://maps.vix.com/rbl/. 279738032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 279838032Speter Local_check_rcpt from check_relay, check_mail, and 279938032Speter check_rcpt. Users with local rulesets should place the 280038032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 280138032Speter returns $#OK, the message is accepted. If the ruleset 280238032Speter returns a mailer, the appropriate action is taken, else 280338032Speter the return of the ruleset is ignored. 280438032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 280538032Speter default to support file, :include:, and program deliveries. 280638032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 280738032Speter pick the proper default value. See the SECURITY note 280838032Speter above for more information. 280938032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 281038032Speter no-op. Patch from Kari Hurtta of the Finnish 281138032Speter Meteorological Institute. 281238032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 281338032Speter daemon since DEC's /bin/mail will drop the envelope 281438032Speter sender if run as mailnull. See the Digital UNIX section 281538032Speter of src/README for more information. Problem noted by 281638032Speter Kari Hurtta of the Finnish Meteorological Institute. 281738032Speter CONFIG: .cf files are now stored in the same directory with the 281838032Speter .mc files instead of in the obj directory. 281964562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 282038032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 282138032Speter setting SingleLineFromHeader, AllowBogusHELO, and 282238032Speter MustQuoteChars respectively. 282338032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.

Problem noted by Kari Hurtta of the Finnish 294138032Speter Meteorological Institute. 294238032Speter If /usr/tmp/dead.letter already existed, sendmail could not 294338032Speter add additional bounces to it. Problem noted by Thomas J. 294438032Speter Arseneault of SRI International. 294538032Speter If an SMTP mailer used a non-standard port number for the outgoing 294638032Speter connection, it would be displayed incorrectly in verbose mode. 294738032Speter Problem noted by John Kennedy of Cal State University, Chico. 294838032Speter Log the ETRN parameter specified by the client before altering them 294938032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 295038032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 295138032Speter User unknown with bogus delay= values. Change them to log 295238032Speter the same as compliant addresses. Problem noted by Kari E. 295338032Speter Hurtta of the Finnish Meteorological Institute. 295438032Speter Ignore the debug resolver option unless using sendmail debug trace 295538032Speter option for resolver. Problem noted by Greg Nichols of Wind 295638032Speter River Systems. 295738032Speter If SingleThreadDelivery was enabled and the remote server returned a 295838032Speter protocol error on the DATA command, the connection would be 295938032Speter closed but the persistent host status file would not be 296038032Speter unlocked so other sendmail processes could not deliver to 296138032Speter that host. Problem noted by Peter Wemm of DIALix. 296238032Speter If queueing up a message due to an expensive mailer, don't increment 296338032Speter the number of delivery attempts or set the last delivery 296438032Speter attempt time so the message will be delivered on the next 296538032Speter queue run regardless of MinQueueAge. Problem noted by 296638032Speter Brian J. Coan of the Institute for Global Communications. 296738032Speter Authentication warnings of "Processed from queue _directory_" and 296838032Speter "Processed by _username_ with -C _filename_" would be logged 296938032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 297038032Speter of the Finnish Meteorological Institute. 297138032Speter Use a better heuristic for detecting GDBM. 297238032Speter Log null connections on dropped connections. Problem noted by 297338032Speter Jon Lewis of Florida Digital Turnpike. 297438032Speter If class dbm maps are rebuilt, sendmail will now detect this and 297538032Speter reopen the map. Previously, they could give stale 297638032Speter results during a single message processing (but would 297738032Speter recover when the next message was received). Fix from 297838032Speter Joe Pruett of Q7 Enterprises. 297938032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 298038032Speter requests. Problem noted by Kari E. Hurtta of the 298138032Speter Finnish Meteorological Institute. 298238032Speter Do not send a bounce message back to the sender regarding bad 298338032Speter recipients if the SMTP connection is dropped before the 298438032Speter message is accepted. Problem noted by Kari E. Hurtta of the 298538032Speter Finnish Meteorological Institute. 298638032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 298738032Speter sendmail via a UNIX pipe. This will allow rulesets using 298838032Speter $&{client_name} to process without sending the string through 298938032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 299038032Speter A combination of deferred delivery mode, a double bounce situation, 299138032Speter and the inability to save a bounce message to 299238032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 299338032Speter to postmaster but not remove the offending envelope from the 299438032Speter queue causing it to create a new bounce message each time the 299538032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 299638032Speter Associates. 299738032Speter Remove newlines from hostname information returned via DNS. There are 299838032Speter no known security implications of newlines in hostnames as 299938032Speter sendmail filters newlines in all vital areas; however, this 300038032Speter could cause confusing error messages. 300138032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 300238032Speter rejected if any of the specified addresses were bad. This 300338032Speter behavior was modified to only reject the bad addresses and not 300438032Speter the entire message. Problem noted by Jozsef Hollosi of 300538032Speter SuperNet, Inc. 300638032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 300738032Speter Bryan Costales of InfoBeat, Inc. 300838032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 300938032Speter mailers. Problem noted by Kari E. Hurtta of the 301038032Speter Finnish Meteorological Institute. 301138032Speter An error in calculating the available space in the list of addresses 301238032Speter for logging deliveries could cause an address to be silently 301338032Speter dropped. 301438032Speter Include the initial user environment if sendmail is restarted via 301538032Speter a HUP signal. This will give room for the process title. 301638032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 301738032Speter Mail could be delivered without a body if the machine does not 301838032Speter support flock locking and runs out of processes during 301938032Speter delivery. Fix from Chuck Lever of the University of Michigan. 302038032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 302138032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 302238032Speter Institute. 302338032Speter Make sure non-rebuildable database maps are opened before the 302464562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 302538032Speter are needed for verifying the left hand side of the aliases. 302638032Speter Problem noted by Lloyd Parkes of Victoria University. 302738032Speter Make sure sender RFC822 source route addresses are alias expanded for 302838032Speter bounce messages. Problem noted by Juergen Georgi of 302938032Speter RUS University of Stuttgart. 303038032Speter Minor lint fixes. 303138032Speter Return a temporary error instead of a permanent error if an LDAP map 303238032Speter search returns an error. This will allow sequenced maps which 303338032Speter use other LDAP servers to be checked. Fix from Booker Bense 303438032Speter of Stanford University. 303538032Speter When automatically converting from quoted printable to 8bit text do 303638032Speter not pad bare linefeeds with a space. Problem noted by Theo 303738032Speter Nolte of the University of Technology Aachen, Germany. 303838032Speter Portability: 303938032Speter Non-standard C compilers may have had a problem compiling 304038032Speter conf.c due to a standard C external declaration of 304138032Speter setproctitle(). Problem noted by Ted Roberts of 304238032Speter Electronic Data Systems. 304338032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 304438032Speter Jagielski of jaguNET Access Services. 304538032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 304638032Speter Digital UNIX: Digital UNIX (and possibly others) moves 304738032Speter loader environment variables into the loader memory 304838032Speter area. If one of these environment variables (such as 304938032Speter LD_LIBRARY_PATH) was the last environment variable, 305038032Speter an invalid memory address would be used by the process 305138032Speter title routine causing memory corruption. Problem 305238032Speter noted by Sam Hartman of Mesa Internet Systems. 305338032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 305438032Speter chownsafe() to always return 0 even if the OS does 305538032Speter not permit file giveaways. Problem noted by 305638032Speter Yasutaka Sumi of The University of Tokyo. 305764562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 305838032Speter Gerald Rinske of Siemens Business Services VAS. 305938032Speter Linux: Pad process title with NULLs. Problem noted by 306038032Speter Jon Lewis of Florida Digital Turnpike. 306138032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 306238032Speter incorrect value for the number of interfaces. 306338032Speter Problem noted by Chris Loelke of JetStream Internet 306438032Speter Services. 306538032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 306638032Speter Rinske of Siemens Business Services VAS. 306738032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 306838032Speter used on a Solaris machine. Problem noted by 306938032Speter Stephen Ma of Jtec Pty Limited. 307038032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 307138032Speter Services VAS. 307238032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 307338032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 307438032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 307538032Speter Ericsson. 307638032Speter 307764562Sgshapiro8.8.7/8.8.7 1997/08/03 307838032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 307938032Speter an exclusive lock already set -- i.e., almost all systems 308038032Speter except 4.4-BSD derived systems), the initial attempt at 308138032Speter rebuilding aliases file if the database didn't already 308238032Speter exist would fail. Patch from Raymund Will of LST Software 308338032Speter GmbH. 308438032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 308538032Speter Problem noted by Fredrik J�nsson of the Royal Institute 308638032Speter of Technology, Stockholm. 308738032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 308838032Speter some environments could give "multiple definitions" for these 308938032Speter routines during compilation. If using TCP Wrappers, assume 309038032Speter that these routines are included as though they were in the 309138032Speter C library. Patch from Robert La Ferla. 309238032Speter When a NEWDB database map was rebuilt at the same time it was being 309338032Speter used by a queue run, the maps could be left locked for the 309438032Speter duration of the queue run, causing other processes to hang. 309538032Speter Problem noted by Kendall Libby of Shore.NET. 309638032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 309738032Speter mail was passed on without any recipient header. This could 309838032Speter cause problems downstream. Problem noted by Xander Jansen 309938032Speter of SURFnet ExpertiseCentrum. 310038032Speter Give error when GDBM is used with sendmail. GDBM's locking and 310138032Speter linking of the .dir and .pag files interferes with sendmail's 310238032Speter locking and security checks. Problems noted by Fyodor 310338032Speter Yarochkin of the Kyrgyz Republic FreeNet. 310438032Speter Don't fsync qf files if SuperSafe option is not set. 310538032Speter Avoid extra calls to gethostbyname for addresses for which a 310638032Speter gethostbyaddr found no value. Also, ignore any returns 310738032Speter from gethostbyaddr that look like a dotted quad. 310838032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 310938032Speter "may be forged", since at the network level we pretty much 311038032Speter have to assume that the information is good. 311138032Speter In some cases, errors during an SMTP session could leave files 311238032Speter open or locked. 311338032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 311480785Sgshapiro Better handling of non-set-user-id binaries -- avoids certain obnoxious 311538032Speter errors during testing. 311638032Speter Errors in file locking of NEWDB maps had the incorrect file name 311738032Speter printed in the error message. 311838032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 311938032Speter missing parameter were issued, the EHLO behaved like a HELO. 312038032Speter Load limiting never kicked in for incoming SMTP transactions if the 312143730Speter DeliveryMode=background and any recipient was an alias or 312238032Speter had a .forward file. From Nik Conwell of Boston University. 312338032Speter On some non-Posix systems, the decision of whether chown(2) permits 312438032Speter file giveaway was undefined. From Tetsu Ushijima of the 312538032Speter Tokyo Institute of Technology. 312638032Speter Fix race condition that could cause the body of a message to be 312738032Speter lost (so only the header was delivered). This only occurs 312838032Speter on systems that do not use flock(2), and only when a queue 312938032Speter runner runs during a critical section in another message 313038032Speter delivery. Based on a patch from Steve Schweinhart of 313138032Speter Results Computing. 313238032Speter If a qf file was found in a mail queue directory that had a problem 313338032Speter (wrong ownership, bad format, etc.) and the file name was 313438032Speter exactly MAXQFNAME bytes long, then instead of being tried 313538032Speter once, it would be tried on every queue run. Problem noted 313638032Speter by Bryan Costales of Mercury Mail. 313738032Speter If the system supports an st_gen field in the status structure, 313838032Speter include it when reporting that a file has changed after open. 313938032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 314038032Speter This out to be checked as well as reported, since it is 314138032Speter theoretically possible for an attacker to remove a file after 314238032Speter it is opened and replace it with another file that has the 314338032Speter same i-number, but some filesystems (notably AFS) return 314438032Speter garbage in this field, and hence always look like the file 314538032Speter has changed. As a practical matter this is not a security 314638032Speter problem, since the files can be neither hard nor soft links, 314738032Speter and on no filesystem (that I am aware of) is it possible to 314838032Speter have two files on the same filesystem with the same i-number 314938032Speter simultaneously. 315038032Speter Delete the root Makefile from the distribution -- it is only for 315138032Speter use internally, and does not work at customer sites. 315238032Speter Fix botch that caused the second MAIL FROM: command in a single 315338032Speter transaction to clear the entire transaction. Problem 315438032Speter noted by John Kennedy of Cal State University, Chico. 315538032Speter Work properly on machines that have _PATH_VARTMP defined without 315638032Speter a trailing slash. (And a pox on vendors that decide to 315738032Speter ignore the established conventions!) Problem noted by 315838032Speter Gregory Neil Shapiro of WPI. 315938032Speter Internal changes to make it easier to add another protocol family 316038032Speter (intended for IPv6). Patches are from John Kennedy of 316138032Speter CSU Chico. 316238032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 316338032Speter an extra space at the beginning of some lines. Problem 316438032Speter noted by Charles Karney of Princeton University; fix based 316538032Speter on a patch from Christophe Wolfhugel. 316638032Speter Portability: 316738032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 316838032Speter with the _Sendmail_ book, 2nd edition. Note that 316938032Speter the book is actually wrong: _PATH_SENDMAILCF should 317038032Speter be used instead. 317138032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 317238032Speter of Argonne National Laboratory. 317338032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 317438032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 317538032Speter SunOS: Include <memory.h> to fix warning from util.c. From 317638032Speter James Aldridge of EUnet Ltd. 317738032Speter Solaris: Change STDIR (location of status file) to /etc/mail 317838032Speter in Makefiles. 317938032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 318038032Speter Makefiles. Use NEWDB on Linux instead. 318138032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 318238032Speter exists but behaves differently than other OSes. 318338032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 318438032Speter around the problem. Problem noted by Tom Moore of 318538032Speter NCR Corp. 318638032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 318738032Speter noted by Tom Smith of Digital Equipment Corp. 318838032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 318938032Speter noted by Tom Good of the Community Access Information 319038032Speter Resource Network 319138032Speter SCO 4.2: compile problems caused by a change in the type of 319238032Speter the "length" parameters passed to accept, getpeername, 319338032Speter getsockname, and getsockopt. Adds new compile flags 319438032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.

This makes it possible to create a root 323938032Speter owned file in an arbitrary directory by inserting the symlink 324038032Speter into a writable directory after the initial lstat(2) check 324138032Speter determined that the file did not exist. The only verified 324238032Speter example of a system having these odd semantics for O_EXCL 324338032Speter and symbolic links was HP-UX prior to version 9.07. Most 324438032Speter systems do not have the problem, since a exclusive create 324538032Speter of a file disallows symbolic links. Systems that have been 324638032Speter verified to NOT have the problem include AIX 3.x, *BSD, 324738032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 324838032Speter and Ultrix. This is a potential exposure on systems that 324938032Speter have this bug and which do not have a MAILER-DAEMON alias 325038032Speter pointing at a legitimate account, since this will cause old 325138032Speter mail to be dropped in /var/tmp/dead.letter. 325238032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 325338032Speter if maps or alias files are in world writable directories. 325438032Speter If your system has alias maps in writable directories, it 325538032Speter is potentially possible for an attacker to replace the .db 325638032Speter (or .dir and .pag) files by symbolic links pointing at 325738032Speter another database; this can be used either to expose 325838032Speter information (e.g., by pointing an alias file at /etc/spwd.db 325938032Speter and probing for accounts), or as a denial-of-service attack 326038032Speter (by trashing the password database). The fix disallows 326138032Speter symbolic links entirely when rebuilding alias files or on 326238032Speter maps that are in writable directories, and always warns on 326338032Speter writable directories; 8.9 will probably consider writable 326438032Speter directories to be fatal errors. This does not represent an 326538032Speter exposure on systems that have alias files in unwritable 326638032Speter system directories. 326738032Speter SECURITY: disallow .forward or :include: files that are links (hard 326838032Speter or soft) if the parent directory (or any directory in the 326938032Speter path) is writable by anyone other than the owner. This is 327038032Speter similar to the previous case for user files. This change 327138032Speter should not affect most systems, but is necessary to prevent 327238032Speter an attacker who can write the directory from pointing such 327338032Speter files at other files that are readable only by the owner. 327438032Speter SECURITY: Tighten safechown rules: many systems will say that they 327538032Speter have a safe (restricted to root) chown even on files that 327638032Speter are mounted from another system that allows owners to give 327738032Speter away files. The new rules are very strict, trusting file 327838032Speter ownership only in those few cases where the system has 327938032Speter been verified to be at least as paranoid as necessary. 328038032Speter However, it is possible to relax the rules to partially 328138032Speter trust the ownership if the directory path is not world or 328238032Speter group writable. This might allow someone who has a legitimate 328338032Speter :include: file (referenced directly from /etc/aliases) to 328438032Speter become another non-root user if the :include: file is in a 328538032Speter non-writable directory on an NFS-mounted filesystem where 328638032Speter the local system says that giveaway is denied but it is 328738032Speter actually permitted. I believe this to be a very small set 328838032Speter of cases. If in doubt, do not point :include: aliases at 328938032Speter NFS-mounted filesystems. 329038032Speter SECURITY: When setting a numeric group id using the RunAsUser option 329138032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 329238032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 329338032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 329438032Speter The user id was still set properly. Problem noted by Uli 329538032Speter Pralle of the Technical University of Berlin. 329638032Speter Save the initial gid set for use when checking for if the 329738032Speter PrivacyOptions=restrictmailq option is set. Problem reported 329838032Speter by Wolfgang Ley of DFN-CERT. 329938032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 330038032Speter failure on one message won't affect future messages to the 330138032Speter same host). 330238032Speter IP source route printing had an "off by one" error that would 330338032Speter affect any options that came after the route option. Patch 330438032Speter from Theo de Raadt. 330538032Speter The "Message is too large" error didn't successfully bounce the error 330638032Speter back to the sender. Problem reported by Stephen More of 330738032Speter PSI; patch from Gregory Neil Shapiro of WPI. 330838032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 330938032Speter of 5.1.3); it apparently gets used in multiple ways. 331038032Speter Suggested by John Myers of Portola Communications. 331138032Speter Fix possible extra null byte generated during collection if errors 331238032Speter occur at the beginning of the stream. Patch contributed by 331338032Speter Andrey A. Chernov and Gregory Neil Shapiro. 331438032Speter Code changes to avoid possible reentrant call of malloc/free within 331538032Speter a signal handler. Problem noted by John Beck of Sun 331638032Speter Microsystems. 331738032Speter Move map initialization to be earlier so that check_relay ruleset 331838032Speter will have the latest version of the map data. Problem noted 331938032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 332038032Speter If there are fatal errors during the collection phase (e.g., message 332138032Speter too large) don't send the bogus message. 332238032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 332338032Speter have errors and have owner- aliases. Problem noted by Michael 332438032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 332538032Speter Avoid null pointer dereference on illegal Boundary= parameters in 332638032Speter multipart/mixed Content-Type: header. Problem noted by 332738032Speter Richard Muirden of RMIT University. 332838032Speter Always print error messages during newaliases (-bi) even if the 332938032Speter ErrorMode is not set to "print". Fix from Gregory Neil 333038032Speter Shapiro. 333138032Speter Test mode could core dump if you did a /map lookup in an optional map 333238032Speter that could not be opened. Based on a fix from John Beck of 333338032Speter Sun Microsystems. 333438032Speter If DNS is misconfigured so that the last MX record tried points to 333538032Speter a host that does not have an A record, but other MX records 333638032Speter pointed to something reasonable, don't bounce the message 333738032Speter with a "host unknown" error. Note that this should really 333838032Speter be fixed in the zone file for the domain. Problem noted by 333938032Speter Joe Rhett of Navigist, Inc. 334038032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 334138032Speter the message as having been tried; otherwise the next queue 334238032Speter run will not realize that this is a second attempt and will 334338032Speter retry immediately. Problem noted by Bryan Costales of 334438032Speter Mercury Mail. 334538032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 334638032Speter will be run until the later setting of the clock is reached. 334738032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 334838032Speter Morgan Stanley. 334938032Speter If the load average rises above the cutoff threshold (above which 335038032Speter sendmail will not process the queue at all) during a queue 335138032Speter run, abort the queue run immediately. Problem noted by 335238032Speter Bryan Costales of Mercury Mail. 335338032Speter The variable queue processing algorithm (based on the message size, 335438032Speter number of recipients, message precedence, and job age) was 335538032Speter non-functional -- either the entire queue was processed or 335638032Speter none of the queue was processed. The updated algorithm 335738032Speter does no queue run if a single recipient zero size job will 335838032Speter not be run. 335938032Speter If there is a fatal ("panic") message that will cause sendmail to 336038032Speter die immediately, never hold the error message for future 336138032Speter printing. 336238032Speter Force ErrorMode=print in -bt mode so that all errors are printed 336338032Speter regardless of the setting of the ErrorMode option in the 336438032Speter configuration file. Patch from Gregory Neil Shapiro. 336538032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 336638032Speter routine available in one of the libraries. Use it in conf.h. 336738032Speter The -m (match only) flag now works on host class maps. 336838032Speter If class hash or btree maps are rebuilt, sendmail will now detect 336938032Speter this and reopen the map. Previously, they could give 337038032Speter erroneous results during a single message processing 337138032Speter (but would recover when the next message was received). 337238032Speter Don't delete zero length queue files when doing queue runs until the 337338032Speter files are at least ten minutes old. This avoids a potential 337438032Speter race condition: the creator creates the qf file, getting back 337538032Speter a file descriptor. The queue runner locks it and deletes it 337638032Speter because it is zero length. The creator then writes the 337738032Speter descriptor that is now for a disconnected file, and the 337838032Speter job goes away. Based on a suggestion by Bryan Costales. 337938032Speter When determining the "validated" host name ($_ macro), do a forward 338038032Speter (A) DNS lookup on the result of the PTR lookup and compare 338138032Speter results. If they differ or if the PTR lookup fails, tag the 338238032Speter address as "may be forged". 338338032Speter Log null connections (i.e., hosts that connect but do not do any 338438032Speter substantive activity on the connection before disconnecting; 338538032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 338638032Speter Always permit "writes" to /dev/null regardless of the link count. 338738032Speter This is safe because /dev/null is special cased, and no open 338838032Speter or write is ever actually attempted. Patch from Villy Kruse 338938032Speter of TwinCom. 339038032Speter If a message cannot be sent because of a 552 (exceeded storage 339138032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 339238032Speter was given, don't return the body in the bounce, since there 339338032Speter is a very good chance that the message will double-bounce. 339438032Speter Fix possible line truncation if a quoted-printable had an =00 escape 339538032Speter in the body. Problem noted by Charles Karney of the Princeton 339638032Speter Plasma Physics Laboratory. 339738032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 339838032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 339938032Speter Institute. 340038032Speter The MaxDaemonChildren option wasn't applying to queue runs as 340138032Speter documented. Note that this increases the potential denial 340238032Speter of service problems with this option: an attacker can 340338032Speter connect many times, and thereby lock out queue runs as well 340438032Speter as incoming connections. If you use this option, you should 340538032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 340638032Speter to avoid this attack. Failure to limit noted by Matthew 340738032Speter Dillon of BEST Internet Communications. 340838032Speter Always give a message in newaliases if alias files cannot be 340938032Speter opened instead of failing silently. Suggested by Gregory 341038032Speter Neil Shapiro. This change makes the code match the O'Reilly 341138032Speter book (2nd edition). 341238032Speter Some older versions of the resolver could return with h_errno == -1 341338032Speter if no name server could be reached, causing mail to bounce 341438032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 341538032Speter John Beck of SunSoft. 341638032Speter If a :include: file is owned by a user that does not have an entry 341738032Speter in the passwd file, sendmail could dereference a null pointer. 341838032Speter Problem noted by Satish Mynam of Sun Microsystems. 341938032Speter Take precautions to make sure that the SMTP protocol cannot get out 342038032Speter of sync if (for example) an alias file cannot be opened. 342138032Speter Fix a possible race condition that can cause a SIGALRM to come in 342238032Speter immediately after a SIGHUP, causing the new sendmail to die. 342338032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 342438032Speter from Villy Kruse of TwinCom. 342538032Speter Ignore improperly formatted SMTP reply codes. Previously these were 342638032Speter partially processed, which could cause confusing error 342738032Speter returns. 342838032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 342938032Speter on some architectures. 343038032Speter Portability: 343138032Speter A/UX: from Jim Jagielski of NASA/GSFC. 343238032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 343338032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 343438032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 343538032Speter defined. Problem reported by A Sun of the University 343638032Speter of Washington. 343738032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 343838032Speter the system rather than guessing at compile time. 343938032Speter Patch contributed by John Beck of Sun Microsystems. 344038032Speter Intel Paragon: from Wendy Lin of Purdue University. 344138032Speter GNU Hurd: from Miles Bader of the GNU project. 344238032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 344338032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 344438032Speter Unfortunately releasing them opens a race condition, 344538032Speter but there appears to be no fix for this. Patch from 344638032Speter Gregory Neil Shapiro. 344738032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 344838032Speter Solaris: a bug in strcasecmp caused characters with the 344938032Speter high order bit set to apparently randomly match 345038032Speter letters -- for example, $| (0233) matches "i" and "I". 345138032Speter Problem noted by John Gregson of the University of 345238032Speter Cambridge. 345338032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 345438032Speter Kari Hurtta. 345538032Speter IRIX 6.x: Create Makefiles for systems that claim to be 345638032Speter IRIX64 but are 6.2 or higher (so use the regular 345738032Speter IRIX Makefile). 345838032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 345938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 346038032Speter CONFIG: Some canonification was still done for UUCP-like addresses 346138032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 346238032Speter Brian Candler. 346338032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 346438032Speter local names as local. Problem noted by Jeff Polk of BSDI; 346538032Speter fix provided by Gregory Neil Shapiro. 346638032Speter CONFIG: The "local:user" syntax entries in mailertables and other 346738032Speter "mailer:user" syntax locations returned an incorrect value 346838032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 346938032Speter CONFIG: Retain "+detail" information when forwarding mail to a 347038032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 347138032Speter Guenther of Gustavus Adolphus College. 347238032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 347338032Speter rules are the same as for aliasing. Based on a patch from 347438032Speter Gregory Neil Shapiro. 347538032Speter CONFIG: Break up parsing rules into several pieces; this should 347638032Speter have no functional change in this release, but makes it 347738032Speter possible to have better anti-spam rulesets in the future. 347838032Speter CONFIG: Disallow double dots in host names to avoid having the 347938032Speter HostStatusDirectory store status under the wrong name. 348038032Speter In some cases this can be used as a denial-of-service attack. 348138032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 348238032Speter Gregory Neil Shapiro. 348338032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 348438032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 348538032Speter don't include From_, and convert to 8-bit). Suggestions 348638032Speter from Kimmo Suominen and Roderick Schertler. 348764562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 348838032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 348938032Speter was specified, even when it wasn't. 349038032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 349138032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 349238032Speter "slip in" a symbolic link between the lstat(2) call and the 349338032Speter exclusive open. This is only a problem on System V derived 349438032Speter systems that allow an exclusive create on files that are 349538032Speter symbolic links pointing nowhere. 349638032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 349738032Speter not reset back to root, which on some systems would cause 349838032Speter later mailboxes to fail. Also, any partial message would 349938032Speter not be truncated, which could result in repeated deliveries. 350038032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 350138032Speter developers). 350238032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 350338032Speter change to the sendmail map code was made in 8.8.3. Problem 350438032Speter noted by Gregory Neil Shapiro. 350538032Speter MAKEMAP: Give warnings on file problems such as map files that are 350680785Sgshapiro symbolic links; although makemap is not set-user-id root, it is 350738032Speter often run as root and hence has the potential for the same 350838032Speter sorts of problems as alias rebuilds. 350938032Speter MAKEMAP: Change compilation so that it will link properly on 351038032Speter NEXTSTEP. 351138032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 351238032Speter Accept an optional list of arguments following the server 351338032Speter name for the ETRN arguments to use (instead of $=w).

This 351738032Speter Perl script converts GECOS information in the /etc/passwd 351838032Speter file into aliases, allowing for faster access to full name 351938032Speter lookups; it is also clever about adding aliases (to root) 352038032Speter for system accounts. 352138032Speter NEW FILES: 352238032Speter src/safefile.c 352338032Speter cf/ostype/gnuhurd.m4 352438032Speter cf/ostype/irix6.m4 352538032Speter contrib/passwd-to-alias.pl 352638032Speter src/Makefiles/Makefile.IRIX64.6.1 352738032Speter src/Makefiles/Makefile.IRIX64.6.x 352838032Speter RENAMED FILES: 352938032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 353038032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 353138032Speter 353264562Sgshapiro8.8.5/8.8.5 1997/01/21 353338032Speter SECURITY: Clear out group list during startup. Without this, sendmail 353438032Speter will continue to run with the group permissions of the caller, 353538032Speter even if RunAsUser is specified. 353638032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 353738032Speter to any known attack, but it's best to be conservative. 353838032Speter Suggested by Peter Wemm of DIALix. 353938032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 354038032Speter security implications. Patch from Alex Garthwaite of the 354138032Speter University of Pennsylvania. 354238032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 354338032Speter would truncate the address after "Full". Although the -f 354438032Speter syntax is incorrect (since it is in the envelope, it 354538032Speter shouldn't have comments and full names), the failure mode 354638032Speter was unnecessarily awful. 354738032Speter Fix a possible null pointer dereference when converting 8-bit data 354838032Speter to a 7-bit format. Problem noted by Jim Hutchins of 354938032Speter Sandia National Labs and David James of British Telecom. 355038032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 355138032Speter runs. Although this really shouldn't be used (F=9 is for 355238032Speter final delivery only, and using it on an SMTP mailer makes 355338032Speter it possible for a message to be converted from 8->7->8->7 355438032Speter bits several times), it shouldn't have failed with a syserr. 355538032Speter Problem noted by Eric Hagberg of Morgan Stanley. 355638032Speter _Really_ fix the multiple :maildrop code in the user database 355738032Speter module. Patch from Roy Mongiovi of Georgia Tech. 355838032Speter Let F lines in the configuration file actually read root-only 355938032Speter files if the configuration file is safe. Based on a 356038032Speter patch from Keith Reynolds of SCO. 356138032Speter ETRN followed by QUIT would hold the connection open until the queue 356238032Speter run completed. Problem noted by Truck Lewis of TDK 356338032Speter Semiconductor Corp. 356438032Speter It turns out that despite the documentation, the TCP wrappers library 356538032Speter does _not_ log rejected connections. Do the logging ourselves. 356638032Speter Problem noted by Fletcher Mattox of the University of Texas 356738032Speter at Austin. 356838032Speter If sendmail finds a qf file in its queue directory that is an unknown 356938032Speter version (e.g., when backing out to an old version), the 357038032Speter error is reported on every queue run. Change it to only 357138032Speter give the error once (and rename the qf => Qf). Patch from 357238032Speter William A. Gianopoulos of Raytheon Company. 357338032Speter Start a new session when doing background delivery; currently it 357438032Speter ignored signals but didn't start a new signal, that caused 357538032Speter some problems if a background process tried to send mail 357638032Speter under certain circumstances. Problem noted by Eric Hagberg 357738032Speter of Morgan Stanley; fix from Kari Hurtta. 357838032Speter Simplify test for skipping a queue run to just check if the current 357938032Speter load average is >= the queueing load average. Previously 358038032Speter the check factored in some other parameters that caused it 358138032Speter to essentially never skip the queue run. Patch from Bryan 358238032Speter Costales. 358338032Speter If the SMTP server is running in "nullserver" mode (that is, it is 358438032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 358538032Speter (25) commands; this helps prevent a bad guy from putting 358638032Speter you into a tight loop as a denial-of-service attack. Based 358738032Speter on an e-mail conversation with Brad Knowles of AOL. 358838032Speter Slow down when too many "light weight" commands have been issued; 358938032Speter this helps prevent a class of denial-of-service attacks. 359038032Speter The current values and defaults are: 359138032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 359238032Speter MAXHELOCOMMANDS 3 HELO, EHLO 359338032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 359438032Speter MAXETRNCOMMANDS 8 ETRN 359538032Speter These will probably be configurable in a future release. 359638032Speter On systems that have uid_t typedefed to be an unsigned short, programs 359738032Speter that had the F=S flag and no U= equate would be invoked with 359838032Speter the real uid set to 65535 rather than being left unchanged. 359938032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 360038032Speter by Steve Hubert of the University of Washington, Seattle. 360138032Speter Mail that was Quoted-Printable encoded and had a soft line break on 360238032Speter the last line (i.e., an incomplete continuation) had the last 360338032Speter line dropped. Since this appears to be illegal it isn't 360438032Speter clear what to do with it, but flushing the last line seems 360538032Speter to be a better "fail soft" approach. Based on a patch from 360638032Speter Eric Hagberg. 360738032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 360838032Speter bogus HELO command still causes the "Polite people say HELO 360938032Speter first" error message. Problem pointed out by Chris Thomas 361038032Speter of UCLA; patch from John Beck of SunSoft. 361138032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 361271345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 361371345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 361471345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 361538032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 361638032Speter in a DATA transaction to be sticky; these can occur because 361738032Speter a message is too large, and smaller messages should still go 361838032Speter through. Problem noted by Matt Dillon of Best Internet 361938032Speter Communications. 362038032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 362138032Speter had been successfully delivered to the envelope sender. 362238032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 362338032Speter Gregory Neil Shapiro of WPI. 362438032Speter Give better diagnostics on long alias lines. Based on code contributed 362538032Speter by Patrick Gosling of the University of Cambridge. 362638032Speter Increase the number of virtual interfaces that will be probed for 362738032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 362838032Speter PORTABILITY: 362938032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 363038032Speter Toshiaki Nomura of Fujitsu Limited. 363138032Speter SunOS with LDAP support: compile problems with struct timeval. 363238032Speter Patch from Nick Cuccia of TCSI Corporation. 363338032Speter SCO: from Keith Reynolds of SCO. 363438032Speter Solaris: kstat load average computation wasn't being used. 363538032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 363638032Speter (Moscow). 363738032Speter OpenBSD: from Jason Downs of teeny.org. 363838032Speter Altos System V: from Tim Rice. 363938032Speter Solaris 2.5: from Alan Perry of SunSoft. 364038032Speter Solaris 2.6: from John Beck of SunSoft. 364138032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 364238032Speter of Pratt & Whitney <miorelli@pweh.com>. 364338032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 364438032Speter _just_right_ yet. Tweak it again. I'll omit the names 364538032Speter of the "contributors" (quantity two) in this one case. 364638032Speter As of now, NO MORE DISCUSSION about the syntax of the 364738032Speter Received: line. 364838032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 364938032Speter it never inserts that class into the output file. Fix it 365038032Speter so it will honor EXPOSED_USER but will _not_ include root 365138032Speter automatically in this class. Problem noted by Ronan KERYELL 365238032Speter of Centre de Recherche en Informatique de l'�cole Nationale 365338032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 365438032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 365538032Speter such as LUSER_RELAY. This change permits the following 365638032Speter syntaxes: ``local:'' will send to the same user on the 365738032Speter local machine (e.g., in a mailertable entry for "host", 365838032Speter ``local:'' will cause an address addressed to user@host to 365938032Speter go to user on the local machone). ``local:user'' will send 366038032Speter to the named user on the local machine. ``local:user@host'' 366138032Speter is equivalent to ``local:user'' (the host is ignored). In 366238032Speter all cases, the original user@host is passed in $@ (i.e., the 366338032Speter detail information). Inspired by a report from Michael Fuhr. 366438032Speter CONFIG: Strip quotes from the first word of an "error:" host 366538032Speter indication. This lets you set (for example) the LUSER_RELAY 366638032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 366738032Speter of the \" so that the resulting string is properly quoted. 366838032Speter Problem noted by Gregory Neil Shapiro of WPI. 366938032Speter OP.ME: documentation was inconsistent about whether sendmail did a 367038032Speter NOOP or a RSET to probe the connection (it does a RSET). 367138032Speter Inconsistency noted by Deeran Peethamparam. 367238032Speter OP.ME: insert additional blank pages so it will print properly on 367338032Speter a duplex printer. From Matthew Black of Cal State University, 367438032Speter Long Beach. 367538032Speter 367664562Sgshapiro8.8.4/8.8.4 1996/12/02 367738032Speter SECURITY: under some circumstances, an attacker could get additional 367838032Speter permissions by hard linking to files that were group 367938032Speter writable by the attacker. The solution is to disallow any 368038032Speter files that have hard links -- this will affect .forward, 368138032Speter :include:, and output files. Problem noted by Terry 368238032Speter Kyriacopoulos of Interlog Internet Services. As a 368338032Speter workaround, set UnsafeGroupWrites -- always a good idea. 368438032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 368538032Speter is, it is possible to do a denial-of-service attack on 368638032Speter MX hosts that rely on the use of the null MX list. There 368738032Speter is no danger if you have this option turned off (the default). 368838032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 368938032Speter unsafe. I know of no specific attack against this, although 369038032Speter a denial-of-service attack is probably possible, but in theory 369138032Speter you should not be able to safely tweak anything that affects 369238032Speter the permissions that are used when mail is delivered. 369338032Speter Purgestat could go into an infinite loop if one of the host status 369438032Speter directories somehow became empty. Problem noted by Roy 369538032Speter Mongiovi of Georgia Tech. 369638032Speter Processes got "lost" when counting children due to a race condition. 369738032Speter This caused "proc_list_probe: lost pid" messages to be logged. 369838032Speter Problem noted by several people. 369938032Speter On systems with System V SIGCLD child signal semantics (notably AIX 370038032Speter and HP-UX), mail transactions would print the message "451 370138032Speter SMTP-MAIL: lost child: No child processes". Problem noted 370238032Speter by several people. 370338032Speter Miscellaneous compiler warnings on picky compilers (or when setting 370438032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 370538032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 370638032Speter not be persistent between runs, since they are based on the 370738032Speter message rather than the host. Problem noted by Matt Dillon 370838032Speter of Best Internet Communications. 370938032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 371038032Speter of NCR (a.k.a., AT&T Global Information Solutions). 371138032Speter Avoid the possibility of having a child daemon run to completion 371238032Speter (including closing the SMTP socket) before the parent has 371338032Speter had a chance to close the socket; this can cause the parent 371438032Speter to hang for a long time waiting for the socket to drain. 371538032Speter Patch from Don Lewis of TDK Semiconductor. 371638032Speter If the fork() failed in a queue run, the queue runners would not be 371738032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 371838032Speter Some error conditions in ETRN could cause output without an SMTP 371938032Speter status code. Problem noted by Don Lewis. 372038032Speter Multiple :maildrop addresses in the user database didn't work properly. 372138032Speter Patch from Roy Mongiovi of Georgia Tech. 372238032Speter Add ".db" automatically onto any user database spec that does not 372338032Speter already have it; this is for consistency with makemap, the 372438032Speter K line, and the documentation. Inconsistency pointed out 372538032Speter by Roy Mongiovi. 372638032Speter Allow sendmail to be properly called in nohup mode. Patch from 372738032Speter Kyle Jones of UUNET. 372838032Speter Change ETRN to ignore but still update host status files; previously 372938032Speter it would ignore them and not save the updated status, which 373038032Speter caused stale information to be maintained. Based on a patch 373138032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 373238032Speter ETRN ignore the MinQueueAge option. 373338032Speter Patch long term host status to recover more gracefully from an empty 373438032Speter host status file condition. Patch from NAKAMURA Motonori 373538032Speter of Kyoto University. 373638032Speter Several patches to signal handling code to fix potential race 373738032Speter conditions from Don Lewis. 373838032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 373938032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 374038032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 374138032Speter compile flag; use NETINET instead. Solution based on a 374238032Speter patch from Bryan Costales. 374338032Speter PORTABILITY FIXES: 374438032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 374538032Speter /etc/security/passwd file when called as root. This 374638032Speter is very slow on some systems. To speed it up, use the 374738032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 374838032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 374938032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 375038032Speter Glicker of Burrelle's Information Service. 375138032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 375238032Speter from Makoto MATSUSHITA of Osaka University. 375338032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 375438032Speter Leeds University and SASABE Tetsuro of the University 375538032Speter of Tokyo. 375638032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 375738032Speter Services, Inc. 375838032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 375938032Speter I believe this to have only been a problem if you 376038032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 376138032Speter to stick with /etc/sendmail.cf as your One True Path. 376238032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 376338032Speter Martin Laubach of the Technischen Universit�t Wien. 376438032Speter CONFIG: change default Received: line to be multiple lines rather 376538032Speter than one long one. By popular demand. 376638032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 376738032Speter from Jerome Berkman of U.C. Berkeley. 376838032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 376938032Speter to take a very long time. Problem noted by Yoshiro YONEYA 377038032Speter of NTT Software Corporation. 377138032Speter CONTRIB: add etrn.pl, contributed by John Beck. 377238032Speter NEW FILES: 377338032Speter contrib/etrn.pl 377438032Speter 377564562Sgshapiro8.8.3/8.8.3 1996/11/17 377638032Speter SECURITY: it was possible to get a root shell by lying to sendmail 377738032Speter about argv[0] and then sending it a signal. Problem noted 377838032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 377938032Speter best-of-security list. 378038032Speter Log sendmail binary version number in "Warning: .cf version level 378138032Speter (%d) exceeds program functionality (%d) message" -- this 378238032Speter should make it clearer to people that they are running 378338032Speter the wrong binary. 378438032Speter Fix a problem that occurs when you open an SMTP connection and then 378538032Speter do one or more ETRN commands followed by a MAIL command; at 378638032Speter the end of the DATA phase sendmail would incorrectly report 378738032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 378838032Speter noted by Eric Bishop of Virginia Tech. 378938032Speter When doing text-based host canonification (typically /etc/hosts 379038032Speter lookup), a null host name would match any /etc/hosts entry 379138032Speter with space at the end of the line. Problem noted by Steve 379238032Speter Hubert of the University of Washington, Seattle. 379338032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 379438032Speter Problem reported by Tom Smith of Digital Equipment Corp. 379538032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 379638032Speter size PACKETSZ (512) is not sufficient for some nameserver 379738032Speter answers containing very many resource records. The resolver 379838032Speter may also switch to TCP and retry if it detects UDP packet 379938032Speter overflow. Also, allow for the fact that the resolver 380038032Speter routines res_query and res_search return the size of the 380138032Speter *un*truncated answer in case the supplied answer buffer it 380238032Speter not big enough to accommodate the entire answer. Patch from 380338032Speter Eric Wassenaar. 380438032Speter Improvements to MaxDaemonChildren code. If you think you have too 380538032Speter many children, probe the ones you have to verify that they 380638032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 380738032Speter Also, do this probe before growing the vector of children 380838032Speter pids; this previously caused the vector to grow indefinitely 380938032Speter due to a race condition. Problem reported by Kyle Jones of 381038032Speter UUNET. 381138032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 381238032Speter O_EXLOCK to zero; this fools the map compilation code into 381338032Speter thinking that it can avoid race conditions by locking on open. 381438032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 381538032Speter Leif Erlingsson of Data Lege. 381638032Speter Always call res_init() on startup (if compiled in, of course) to 381738032Speter allow the sendmail.cf file to tweak resolver flags; without 381838032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 381938032Speter Andrew Sun of Merrill Lynch. 382038032Speter Improvements to host status printing code. Suggested by Steve Hubert 382138032Speter of the University of Washington, Seattle. 382238032Speter Change MinQueueAge option processing to do the check for the job age 382338032Speter when reading the queue file, rather than at the end; this 382438032Speter avoids parsing the addresses, which can do DNS lookups. 382538032Speter Problem noted by John Beck of InReference, Inc. 382638032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 382738032Speter properly escaped. Problem noted by Peter Nilsson of the 382838032Speter University of Linkoping. 382938032Speter In some cases, sendmail would retain root permissions during queue 383038032Speter runs even if RunAsUser was set. Problem noted by Mark 383138032Speter Thomas of Mark G. Thomas Consulting. 383238032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 383338032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 383438032Speter the envelope, and the receiving SMTP server speaks DSN, then 383538032Speter the DSN would be both generated locally and propagated to the 383638032Speter other end. 383738032Speter The U= mailer field didn't correctly extract the group id if the 383838032Speter user id was numeric. Problem noted by Kenneth Herron of 383938032Speter MCI Telecommunications Communications. 384038032Speter If a message exceeded the fixed maximum size on input, the body of 384138032Speter the message was included in the bounce. Note that this did 384238032Speter not occur if it exceeded the maximum _output_ size. Problem 384338032Speter reported by Kyle Jones of UUNET. 384438032Speter PORTABILITY FIXES: 384538032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 384638032Speter AIX4 defines to use seteuid(2) instead, which 384738032Speter works on 4.1 as well as 4.2. Problem noted by 384838032Speter H�kan Lindholm of interAF, Sweden. 384938032Speter AIX4: use tzname[] vector to determine time zone name. 385038032Speter Patch from NAKAMURA Motonori of Kyoto University. 385138032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 385238032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 385338032Speter Solaris: kstat(3k) support for retrieving the load average. 385438032Speter This adds the LA_KSTAT definition for LA_TYPE. 385538032Speter The outline of the implementation was contributed 385638032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 385738032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 385838032Speter declaration of struct rusage at the top of conf.h; 385938032Speter change it to only be included if you are using gcc, 386038032Speter which is apparently the only compiler that requires 386138032Speter it in the first place. Problem noted by Jeff 386238032Speter Earickson of Colby College. 386338032Speter IRIX: don't default to using gcc. IRIX is a civilized 386438032Speter operating system that comes with a decent compiler 386538032Speter by default. Problem noted by Barry Bouwsma and 386638032Speter Kari Hurtta. 386738032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 386838032Speter consistency with other local mailers. Inconsistency 386938032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 387038032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 387138032Speter overhead) as part of the bestmx_is_local feature, the 387238032Speter domain part was dropped from the name. Patch from Steve 387338032Speter Hubert of the University of Washington, Seattle. 387438032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 387538032Speter end up being translated to the null host name, which would 387638032Speter return any entry in /etc/hosts that had a space at the end 387738032Speter of the line. Problem noted by Steve Hubert of the 387838032Speter University of Washington, Seattle. 387938032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 388038032Speter Polytechnic Institute. 388138032Speter MAKEMAP: tweak hash and btree parameters for better performance. 388238032Speter Patch from Matt Dillon of Best Internet Communications. 388338032Speter NEW FILES: 388438032Speter src/Makefiles/Makefile.Linux.ppc 388538032Speter cf/ostype/aix4.m4 388638032Speter cf/ostype/mklinux.m4 388738032Speter 388864562Sgshapiro8.8.2/8.8.2 1996/10/18 388938032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 389038032Speter changed the code but didn't fix the problem. 389138032Speter PORTABILITY FIXES: 389238032Speter Solaris: Don't use the system getusershell(3); it can 389338032Speter apparently corrupt the heap in some circumstances. 389438032Speter Problem found by Ken Pizzini of Spry, Inc. 389538032Speter OP.ME: document several mailer flags that were accidentally omitted 389638032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 389738032Speter CONFIG: no changes. 389838032Speter 389964562Sgshapiro8.8.1/8.8.1 1996/10/17 390038032Speter SECURITY: unset all environment variables that the resolver will 390138032Speter examine during queue runs and daemon mode. Problem noted 390238032Speter by Dan Bernstein of the University of Illinois at Chicago. 390338032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 390438032Speter message could overflow a buffer if it was converted back 390538032Speter to 8 bits. This caused core dumps and has the potential 390638032Speter for a remote attack. Problem first noted by Gregory Shapiro 390738032Speter of WPI. 390838032Speter Avoid duplicate deliveries of error messages on systems that don't 390938032Speter have flock(2) support. Patch from Motonori Nakamura of 391038032Speter Kyoto University. 391138032Speter Ignore null FallBackMX (V) options. If this option is null (as 391238032Speter opposed to undefined) it can cause "null signature" syserrs 391338032Speter on illegal host names. 391438032Speter If a Base64 encoded text/plain message has no trailing newline in 391538032Speter the encoded text, conversion back to 8 bits will drop the 391638032Speter final line. Problem noted by Pierre David. 391738032Speter If running with a RunAsUser, sendmail would give bogus "cannot 391838032Speter setuid" (or seteuid, or setreuid) messages on some systems. 391938032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 392038032Speter Always print error messages in -bv mode -- previously, -bv would 392138032Speter be absolutely silent on errors if the error mode was sent 392238032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 392338032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 392438032Speter term host status. This is necessary because it is common 392538032Speter to do this when you know a host has just come back up. 392638032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 392738032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 392838032Speter University of Leicester. 392938032Speter If a service (such as NIS) is specified as the last entry in the 393038032Speter service switch, but that service is not compiled in, sendmail 393138032Speter would return a temporary failure when an entry was not found 393238032Speter in the map. This caused the message to be queued instead of 393338032Speter bouncing immediately. Problem noted by Harry Edmon of the 393438032Speter University of Washington. 393538032Speter PORTABILITY FIXES: 393638032Speter Solaris 2.3 had compilation problems in conf.c. Several 393738032Speter people pointed this out. 393838032Speter NetBSD from Charles Hannum of MIT. 393938032Speter AIX4 improvements based on info from Steve Bauer of South 394038032Speter Dakota School of Mines & Technology. 394138032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 394238032Speter Patch from Gil Kloepfer Jr. 394338032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 394438032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 394538032Speter were also in $=w. Problem noted by Zoltan Basti of 394638032Speter Softec. 394738032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 394838032Speter on a patch from Eric Hagberg of Morgan Stanley. 394938032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 395038032Speter of Stanford via Robert La Ferla. 395138032Speter 395264562Sgshapiro8.8.0/8.8.0 1996/09/26 395338032Speter Under some circumstances, Bcc: headers would not be properly 395438032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 395538032Speter Log a warning if the sendmail daemon is invoked without a full 395638032Speter pathname, which prevents "kill -1" from working. I was 395738032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 395838032Speter Fix small buffer overflow. Since the data in this buffer was not 395938032Speter read externally, there was no security problem (and in fact 396038032Speter probably wouldn't really overflow on most compilers). Pointed 396138032Speter out by KIZU takashi of Osaka University. 396238032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 396338032Speter if a FallbackMXHost was specified in the configuration file 396438032Speter -- all mail would be sent to the fallback even if the original 396538032Speter host was accessible. Pointed out by Munenari Hirayama of 396638032Speter NSC (Japan). 396738032Speter A message that didn't terminate with a newline would (sometimes) not 396838032Speter have the trailing "." added properly in the SMTP dialogue, 396938032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 397038032Speter The DaemonPortOptions suboption to bind to a particular address was 397138032Speter incorrect and nonfunctional due to a misunderstanding of the 397238032Speter semantics of binding on a passive socket. Patch from 397338032Speter NIIBE Yutaka of Mitsubishi Research Institute. 397438032Speter Increase the number of MX hosts for a single name to 100 to better 397538032Speter handle the truly huge service providers such as AOL, which 397638032Speter has 13 at the moment (and climbing). In order to avoid 397738032Speter trashing memory, the buffer for all names has only been 397838032Speter slightly increased in size, to 12.8K from 10.2K -- this means 397938032Speter that if a single name had 100 MX records, the average size 398038032Speter of those records could not exceed 128 bytes. Requested by 398138032Speter Brad Knowles of America On Line. 398238032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 398338032Speter Urged by Dan Bernstein of U.C. Berkeley. 398438032Speter Print q_statdate and q_specificity in address structure debugging 398538032Speter printout. 398638032Speter Expand MCI structure flag bits for debugging output. 398738032Speter Support IPv6-style domain literals, which can have colons between 398838032Speter square braces. 398938032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 399038032Speter this is an attempt to track down a bug that one person seems 399138032Speter to be having (it may be a Solaris bug!). 399238032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 399338032Speter this caused the NOTIFY info to sometimes be lost. Problem 399438032Speter pointed out by Claus Assmann of the 399538032Speter Christian-Albrechts-University of Kiel. 399638032Speter The statistics gathered in the sendmail.st file were too high; in 399738032Speter some cases failures (e.g., user unknown or temporary failure) 399838032Speter would count as a delivery as far as the statistics were 399938032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 400038032Speter Systems that don't have flock() would not send split envelopes in 400138032Speter the initial run. Problem pointed out by Leonard Zubkoff of 400238032Speter Dandelion Digital. 400338032Speter Move buffer overflow checking -- these primarily involve distrusting 400438032Speter results that may come from NIS and DNS. 400538032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 400638032Speter include <paths.h> and hence had the wrong pathnames for a few 400738032Speter things like /var/tmp. Reported by Matthew Green. 400838032Speter Conditions were reversed for the Priority: header, resulting in all 400938032Speter values being interpreted as non-urgent except for non-urgent, 401038032Speter which was interpreted as normal. Patch from Bryan Costales. 401138032Speter The -o (optional) flag was being ignored on hash and btree maps 401238032Speter since 8.7.2. Fix from Bryan Costales. 401338032Speter Content-Types listed in class "q" will always be encoded as 401438032Speter Quoted-Printable (or more accurately, will never be encoded 401538032Speter as base64). The class can have primary types (e.g., "text") 401638032Speter or full types (e.g., "text/plain"). Based on a suggestion by 401738032Speter Marius Olafsson of the University of Iceland. 401838032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 401938032Speter dialogue) so it can be passed to programs in mailers. 402038032Speter Define ${bodytype} to be the body type (from the -B flag or the 402138032Speter BODY= ESMTP parameter) so it can be passed to programs in 402238032Speter mailers. 402338032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 402438032Speter flag is set in the mailer descriptor. Suggested by John 402538032Speter Myers of CMU. 402638032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 402738032Speter The command takes a host name; data for that host is 402838032Speter immediately (and asynchronously) flushed. Because this shares 402938032Speter the -qR implementation, other hosts may be attempted, but 403038032Speter there should be no security implications. Implementation 403138032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 403238032Speter Add three new command line flags to pass in DSN parameters: -V envid 403338032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 403438032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 403538032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 403638032Speter that the -N flag applies to all recipients; there is no way 403738032Speter to specify per-address notifications on the command line, 403838032Speter nor is there an equivalent for the ORCPT= per-address 403938032Speter parameter. 404038032Speter Restore LogLevel option to be safe (it can only be increased); 404138032Speter apparently I went into paranoid mode between 8.6 and 8.7 404238032Speter and made it unsafe. Pointed out by Dabe Murphy of the 404338032Speter University of Maryland. 404438032Speter New logging on log level 15: all SMTP traffic. Patches from 404538032Speter Andrew Gross of San Diego Supercomputer Center. 404638032Speter NetInfo property value searching code wasn't stopping when it found 404738032Speter a match. This was causing the wrong values to be found (and 404838032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 404938032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 405038032Speter out by Bill Wisner of Electronics for Imaging that you can't 405138032Speter use the bracket address form for the MAIL_HUB macro, since 405238032Speter that causes the brackets to remain in the envelope recipient 405338032Speter address used for delivery. The simple fix (stripping off the 405438032Speter brackets in the config file) breaks the use of IP literal 405538032Speter addresses. This flag will solve that problem. 405638032Speter Add MustQuoteChars option. This is a list of characters that must 405738032Speter be quoted if they are found in the phrase part of an address 405838032Speter (that is, the full name part). The characters @,;:\()[] are 405938032Speter always in this list and cannot be removed. The default is 406038032Speter this list plus . and ' to match RFC 822. 406138032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 406238032Speter that do not include a host name for back compatibility with 406338032Speter some stupid SMTP clients. Setting this violates RFC 1123 406438032Speter section 5.2.5. 406538032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 406638032Speter rejecting connections if it has more than this many 406738032Speter outstanding children accepting mail. Note that you may 406838032Speter see more processes than this because of outgoing mail; this 406938032Speter is for incoming connections only. 407038032Speter Add ConnectionRateThrottle option. If set to a positive value, the 407138032Speter number of incoming SMTP connections that will be permitted 407238032Speter in a single second is limited to this number. Connections are 407338032Speter not refused during this time, just deferred. The intent is to 407438032Speter flatten out demand so that load average limiting can kick in. 407538032Speter It is less radical than MaxDaemonChildren, which will stop 407638032Speter accepting connections even if all the connections are idle 407738032Speter (e.g., due to connection caching). 407838032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 407938032Speter specifies how long cached information about the state of a 408038032Speter host will be kept before they are considered stale and the 408138032Speter host is retried. If you are using persistent host status 408238032Speter (i.e., the HostStatusDirectory option is set) this will apply 408338032Speter between runs; otherwise, it applies only within a single queue 408438032Speter run and hence is useful only for hosts that have large queues 408538032Speter that take a very long time to run. 408638032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 408738032Speter into being a single line even if they had newlines in them 408838032Speter when read. This is to get around a botch in Lotus Notes. 408938032Speter Text class maps were totally broken -- if you ever retrieved the last 409038032Speter item in a table it would be truncated. Problem noted by 409138032Speter Gregory Neil Shapiro of WPI. 409238032Speter Extend the lines printed by the mailq command (== the -bp flag) when 409338032Speter -v is given to 120 characters; this allows more information 409438032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 409538032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 409638032Speter this was treated as end-of-input. Problem noted by Bryan 409738032Speter Costales. 409838032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 409938032Speter to the queue file. Fix from John Hughes of Atlantic 410038032Speter Technologies, Inc. 410138032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 410238032Speter if this happens in a queue run it can cause nasty delays. 410338032Speter Problem noted by Mark Horton of AT&T. 410438032Speter If userdb entries pointed to userdb entries, and there were multiple 410538032Speter values for a given key, the database cursor would get 410638032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 410738032Speter of Georgia Tech. Fixed by reading all the values and creating 410838032Speter a comma-separated list; thus, the -v output will be somewhat 410938032Speter different for this case. 411038032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 411138032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 411238032Speter of Stanford University. 411338032Speter When envelopes were split due to aliases with owner- aliases, and 411438032Speter there was some error on one of the lists, more than one of 411538032Speter the owners would get the message. Problem pointed out by 411638032Speter Roy Mongiovi of Georgia Tech. 411738032Speter Detect excessive recursion in macro expansions, e.g., $X defined 411838032Speter in terms of $Y which is defined in terms of $X. Problem 411938032Speter noted by Bryan Costales; patch from Eric Wassenaar. 412038032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 412138032Speter some cases get trashed causing bogus From_ lines. Fix from 412238032Speter Kyle Jones of UUNET. 412338032Speter When doing load average initialization, if the nlist call for avenrun 412438032Speter failed, the second and subsequent lookups wouldn't notice 412538032Speter that fact causing bogus load averages to be returned. Noted 412638032Speter by Casper Dik of Sun Holland. 412738032Speter Fix problem with incompatibility with some versions of inet_aton that 412838032Speter have changed the return value to unsigned, so a check for an 412938032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 413038032Speter This could cause mail to addresses such as [foo.com] to bounce 413138032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 413238032Speter Pasteur Institute. 413338032Speter DSNs were inconsistent if a failure occurred during the DATA phase 413438032Speter rather than the RCPT phase: the Action: would be correct, but 413538032Speter the detailed status information would be wrong. Problem noted 413638032Speter by Bob Snyder of General Electric Company. 413738032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 413838032Speter that this is the initial MUA->MTA submission. The flag current 413938032Speter does nothing, but in future releases (when MUAs start using 414038032Speter these flags) it will probably turn on things like DNS 414138032Speter canonification. 414238032Speter Default end-of-line string (E= specification on mailer [M] lines) 414338032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 414438032Speter mailers. 414538032Speter Change the internal definition for the *file* and *include* mailers 414638032Speter to have $u in the argument vectors so that they aren't 414738032Speter misinterpreted as SMTP mailers and thus use \r\n line 414838032Speter termination. This will affect anyone who has redefined 414938032Speter either of these in their configuration file. 415038032Speter Don't assume that IDENT servers close the connection after a query; 415138032Speter responses can be newline terminated. From Terry Kennedy of 415238032Speter St. Peter's College. 415338032Speter Avoid core dumps on erroneous configuration files that have 415438032Speter $#mailer with nothing following. From Bryan Costales. 415538032Speter Avoid null pointer dereference with high debug values in unlockqueue. 415638032Speter Fix from Randy Martin of Clemson University. 415738032Speter Fix possible buffer overrun when expanding very large macros. Fix 415838032Speter from Kyle Jones of UUNET. 415938032Speter After 25 EXPN or VRFY commands, start pausing for a second before 416038032Speter processing each one. This avoids a certain form of denial 416138032Speter of service attack. Potential attack pointed out by Bryan 416238032Speter Costales. 416338032Speter Allow new named (not numbered!) config file rules to do validity 416438032Speter checking on SMTP arguments: check_mail for MAIL commands and 416538032Speter check_rcpt for RCPT commands. These rulesets can do anything 416638032Speter they want; their result is ignored unless they resolve to the 416738032Speter $#error mailer, in which case the indicated message is printed 416838032Speter and the command is rejected. Similarly, the check_compat 416938032Speter ruleset is called before delivery with "from_addr $| to_addr" 417038032Speter (the $| is a meta-symbol used to separate the two addresses); 417138032Speter it can give a "this sender can't send to this recipient" 417238032Speter notification. Note that this patch allows $| to stand alone 417338032Speter in rulesets. 417438032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 417538032Speter that have the name, IP address, and port number (respectively) 417638032Speter of the SMTP client (that is, the entity at the other end of 417738032Speter the connection. These can be used in (e.g.) check_rcpt to 417838032Speter verify that someone isn't trying to relay mail through your 417938032Speter host inappropriately. Be sure to use the deferred evaluation 418038032Speter form, for example $&{client_name}, to avoid having these bound 418138032Speter when sendmail reads the configuration file. 418238032Speter Add new config file rule check_relay to check the incoming connection 418338032Speter information. Like check_compat, it is passed the host name 418438032Speter and host address separated by $| and can reject connections 418538032Speter on that basis. 418638032Speter Allow IDA-style recursive function calls. Code contributed by Mark 418738032Speter Lovell and Paul Vixie. 418838032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 418938032Speter a virtual UUCP address using either a domain address or the $k 419038032Speter macro. Based on code contributed by Mark Lovell and Paul 419138032Speter Vixie. 419238032Speter Add Stanford LDAP map. Requires special libraries that are not 419338032Speter included with sendmail. Contributed by Booker C. Bense 419438032Speter <bbense@networking.stanford.edu>; contact him for support. 419538032Speter See also the src/READ_ME file. 419638032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 419738032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 419838032Speter only for debugging deep bits of code where it is important to 419938032Speter distinguish between the single-character metasymbol $+ and the 420038032Speter two characters $, +. 420138032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 420238032Speter debug_dumpstate. 420338032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 420438032Speter files that are group writable are considered "unsafe" -- that 420538032Speter is, programs and files referenced from such files are not 420638032Speter valid recipients. 420738032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 420838032Speter name that was not in DNS or was a domain-literal. Problem 420938032Speter noted by Tom May. 421038032Speter Change the introduction to error messages to more clearly delineate 421138032Speter permanent from temporary failures; if both existed in a 421238032Speter single message it could be confusing. Suggested by John 421338032Speter Beck of InReference, Inc. 421438032Speter The IngoreDot (i) option didn't work for lines that were terminated 421538032Speter with CRLF. Problem noted by Ted Stockwell of Secure 421638032Speter Computing Corporation. 421738032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 421838032Speter message headers. Problem reported by Matt Dillon of Best 421938032Speter Internet Communications. 422038032Speter Check for bogus characters in the 0200-0237 range; since these are 422138032Speter used internally, very strange errors can occur if those 422238032Speter characters appear in headers. Problem noted by Anders Gertz 422338032Speter of Lysator. 422438032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 422538032Speter recipient mailer has the F=9 flag set, and only works on 422638032Speter text/plain body types. Code contributed by Marius Olafsson 422738032Speter of the University of Iceland. 422838032Speter Special case "postmaster" name so that it is always treated as lower 422938032Speter case in alias files regardless of configuration settings; 423038032Speter this prevents some potential problems where "Postmaster" or 423138032Speter "POSTMASTER" might not match "postmaster". In most cases 423238032Speter this change is a no-op. 423338032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 423438032Speter Costales. 423538032Speter The -a map flag was ignored for dequote maps. Problem noted by 423638032Speter Bryan Costales. 423738032Speter Fix core dump when a lookup of a class "prog" map returns no 423838032Speter response. Patch from Bryan Costales. 423938032Speter Log instances where sendmail is deferring or rejecting connections 424038032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 424138032Speter Include port number in process title for network daemons. Suggested 424238032Speter by Kyle Jones of UUNET. 424338032Speter Send ``double bounces'' (errors that occur when sending an error 424438032Speter message) to the address indicated in the DoubleBounceAddress 424538032Speter option (default: postmaster). Previously they were always 424638032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 424738032Speter Add new mode, -bD, that acts like -bd in all respects except that 424838032Speter it runs in foreground. This is useful for using with a 424938032Speter wrapper that "watches" system services. Suggested by Kyle 425038032Speter Jones of UUNET. 425138032Speter Fix botch in spacing around (parenthesized) comments in addresses 425238032Speter when the comment comes before the address. Patch from 425338032Speter Motonori Nakamura of Kyoto University. 425438032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 425538032Speter that are being bounced to postmaster, rather than "Returned 425638032Speter mail". This permits the person who is postmaster more 425738032Speter easily determine what messages are to their role as 425838032Speter postmaster versus bounces to mail they actually sent. Based 425938032Speter on a suggestion by Motonori Nakamura. 426038032Speter Add new value "time" for QueueSortOrder option; this causes the queue 426138032Speter to be sorted strictly by the time of submission. Note that 426243730Speter this can cause very bad behavior over slow lines (because 426338032Speter large jobs will tend to delay small jobs) and on nodes with 426438032Speter heavy traffic (because old things in the queue for hosts that 426538032Speter are down delay processing of new jobs). Also, this does not 426638032Speter guarantee that jobs will be delivered in submission order 426738032Speter unless you also set DeliveryMode=queue. In general, it should 426838032Speter probably only be used on the command line, and only in 426938032Speter conjunction with -qRhost.domain. In fact, there are very few 427038032Speter cases where it should be used at all. Based on an 427138032Speter implementation by Motonori Nakamura. 427238032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 427338032Speter the same manner as other rulesets. Previously a temporary 427438032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 427538032Speter of Stanford University. 427638032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 427738032Speter 5yz (permanent failure) code. The next MX host will still be 427838032Speter tried if the connection cannot be opened in the first place 427938032Speter or if the MAIL command returns a 4yz (temporary failure) code. 428038032Speter (It's hard to know what to do here, since neither RFC 974 nor 428138032Speter RFC 1123 specify when to proceed to the next MX host.) 428238032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 428338032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 428438032Speter This causes map lookups that get a temporary failure (e.g., 428538032Speter name server failure) to _not_ defer the delivery of the 428638032Speter message. This should only be used if your configuration file 428738032Speter is prepared to do something sensible in this case. Based on 428838032Speter an idea by Gregory Shapiro of WPI. 428938032Speter Fix problem finding network interface addresses. Patch from 429038032Speter Motonori Nakamura. 429138032Speter Don't reject qf entries that are not owned by your effective uid if 429280785Sgshapiro you are not running set-user-id; this makes management of 429380785Sgshapiro certain kinds of firewall setups difficult. Patch 429480785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 429538032Speter Add persistent host status. This keeps the information normally 429638032Speter maintained within a single queue run in disk files that are 429738032Speter shared between sendmail instances. The HostStatusDirectory 429838032Speter is the directory in which the information is maintained. If 429938032Speter not set, persistent host status is turned off. If not a full 430038032Speter pathname, it is relative to the queue directory. A common 430138032Speter value is ".hoststat". 430238032Speter There are also two new operation modes: 430338032Speter * -bh prints the status of hosts that have had recent 430438032Speter connections. 430538032Speter * -bH purges the host statuses. No attempt is made to save 430638032Speter recent status information. 430738032Speter This feature was originally written by Paul Vixie of Vixie 430838032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 430938032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 431038032Speter with my insistence that things fit cleanly into the V8 431138032Speter framework is gratefully appreciated. 431238032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 431338032Speter operate). Avoids letting two sendmails on the local machine 431464562Sgshapiro open connections to the same remote host at the same time. 431538032Speter This reduces load on the other machine, but can cause mail to 431638032Speter be delayed (for example, if one sendmail is delivering a huge 431738032Speter message, other sendmails won't be able to send even small 431838032Speter messages). Also, it requires another file descriptor (for the 431938032Speter lock file) per connection, so you may have to reduce 432038032Speter ConnectionCacheSize to avoid running out of per-process 432138032Speter file descriptors. Based on the persistent host status code 432238032Speter contributed by Paul Vixie and Mark Lovell. 432338032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 432438032Speter SafeFileEnvironment option is set. Problem noted by Bryan 432538032Speter Costales. 432638032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 432738032Speter file. Problem noted by Bryan Costales. 432838032Speter If a job was aborted using the interrupt signal (e.g., control-C from 432938032Speter the keyboard), on some occasions an empty df file would be 433038032Speter left around; these would collect in the queue directory. 433138032Speter Problem noted by Bryan Costales. 433238032Speter Change the makesendmail script to enhance the search for Makefiles 433338032Speter based on release number. For example, on SunOS 5.5.1, it will 433438032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 433538032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 433638032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 433738032Speter Webmasters. 433838032Speter When creating maps using "newaliases", always map the keys to lower 433938032Speter case when creating the map unless the -f flag is specified on 434038032Speter the map itself. Previously this was done based on the F=u 434138032Speter flag in the local mailer, which meant you could create aliases 434238032Speter that you could never access. Problem noted by Bob Wu of DEC. 434338032Speter When a job was read from the queue, the bits causing notification on 434438032Speter failure or delay were always set. This caused those 434538032Speter notifications to be sent even if NOTIFY=NEVER had been 434638032Speter specified. Problem noted by Steve Hubert of the University 434738032Speter of Washington, Seattle. 434838032Speter Add new configurable routine validate_connection (in conf.c). This 434938032Speter lets you decide if you are willing to accept traffic from 435038032Speter this host. If it returns FALSE, all SMTP commands will return 435138032Speter "550 Access denied". -DTCPWRAPPERS will include support for 435238032Speter TCP wrappers; you will need to add -lwrap to the link line. 435338032Speter (See src/READ_ME for details.) 435438032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 435538032Speter bounces. Some people seemed to think that this could be 435638032Speter confusing (even though it is true). Suggested by Motonori 435738032Speter Nakamura. 435838032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 435938032Speter user early in processing to avoid potential security problems. 436038032Speter However, this means that all .forward and :include: files must 436138032Speter be readable by that user, and all files to be written must be 436238032Speter writable by that user and all programs will be executed by that 436338032Speter user. It is also incompatible with the SafeFileEnvironment 436438032Speter option. In other words, it may not actually add much to 436538032Speter security. However, it should be useful on firewalls and other 436638032Speter places where users don't have accounts and the aliases file is 436738032Speter well constrained. 436838032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 436938032Speter only on the first attempt to delivery to an address. It could 437038032Speter be set to be lower than Timeout.connect on the principle that 437138032Speter the mail should go through quickly to responsive hosts; less 437238032Speter responsive hosts get to wait for the next queue run. 437338032Speter Fix a problem on Solaris that occasionally causes programs 437438032Speter (such as vacation) to hang with their standard input connected 437538032Speter to a UDP port. It also created some signal handling problems. 437638032Speter The problems turned out to be an interaction between vfork(2) 437738032Speter and some of the libraries, particularly NIS/NIS+. I am 437838032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 437938032Speter Change user class map to do the same matching that actual delivery 438038032Speter will do instead of just a /etc/passwd lookup. This adds 438138032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 438238032Speter The Timeout.* options are not safe -- they can be used to create a 438338032Speter denial-of-service attack. Problem noted by Christophe 438438032Speter Wolfhugel. 438543730Speter Don't send PostmasterCopy messages in the event of a "delayed" 438638032Speter notification. Suggested by Barry Bouwsma. 438738032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 438838032Speter option is set, since this disables VERB mode. Suggested 438938032Speter by John Hawkinson of MIT. 439038032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 439138032Speter by Motonori Nakamura of Kyoto University. 439238032Speter Only queue messages on transient .forward open failures if there 439343730Speter were no successful opens. The previous behavior caused it 439438032Speter to queue even if a "fall back" .forward was found. Problem 439538032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 439638032Speter and Computer Science (DISCS), NUS, Singapore. 439738032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 439838032Speter is bouncing because of a MIME error during 8->7 bit conversion; 439938032Speter the encapsulated message will bounce again, causing a loop. 440038032Speter Problem noted by Steve Hubert of the University of Washington. 440138032Speter Create xf (transcript) files using the TempFileMode option value 440238032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 440338032Speter National University of Singapore. 440438032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 440538032Speter detect cases where DefaultUid is set to something that the 440638032Speter system can't cope with. 440738032Speter PORTABILITY FIXES: 440838032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 440938032Speter Atlas International. 441038032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 441138032Speter <bicknell@ufp.org>. 441238032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 441338032Speter work on the first recipient of a message due to a 441438032Speter bug in the getpwent family.

Based on a patch from Randall 445738032Speter Winchester of the University of Maryland. 445838032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 445938032Speter Robert La Ferla of Hot Software. 446038032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 446138032Speter (where "code" is an exit status) on domains (previously 446238032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 446338032Speter Foundation. 446438032Speter CONFIG: hooks for IPv6-style domain literals. 446538032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 446638032Speter if it is undefined the AliasFile option is never set; this 446738032Speter should be transparent for most everyone. Suggested by John 446838032Speter Myers of CMU. 446938032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 447038032Speter domain listed in $=w is masqueraded. With it, only those 447138032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 447238032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 447338032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 447438032Speter hosts under those domains as well as the domain headers 447538032Speter themselves. For example, if a configuration had 447638032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 447738032Speter foo.com would be masqueraded; with it, *.foo.com would be 447838032Speter masqueraded as well. Based on an implementation by Richard 447938032Speter (Pug) Bainter of U. Texas. 448038032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 448138032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 448238032Speter Keys are user names; values are outgoing mail addresses. Yes, 448338032Speter this does overlap with the user database, and figuring out 448438032Speter just when to use which one may be tricky. Based on code 448538032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 448638032Speter from Per Hedeland of Ericsson. 448738032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 448838032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 448938032Speter Keys are either fully qualified addresses or just the host 449038032Speter part (with the @ sign). For example, a table containing: 449138032Speter info@foo.com foo-info 449238032Speter info@bar.com bar-info 449338032Speter @baz.org jane@elsewhere.net 449438032Speter would send all mail destined for info@foo.com to foo-info 449538032Speter (which is presumably an alias), mail addressed to info@bar.com 449638032Speter to bar-info, and anything addressed to anyone at baz.org will 449738032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 449838032Speter and baz.org must all be in $=w. Based on discussions with 449938032Speter a great many people. 450038032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 450138032Speter Suggested by Richard Bainter. 450238032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 450338032Speter "fax" mailer. 450438032Speter CONFIG: allow mailertable entries to resolve to local:user; this 450538032Speter passes the original user@host in to procmail-style local 450638032Speter mailers as the "detail" information to allow them to do 450738032Speter additional clever processing. From Joe Pruett of 450838032Speter Teleport Corporation. Delivery to the original user can 450938032Speter be done by specifying "local:" (with nothing after the colon). 451038032Speter CONFIG: allow any context that takes "mailer:domain" to also take 451138032Speter "mailer:user@domain" to force mailing to the given user; 451238032Speter "local:user" can also be used to do local delivery. This 451338032Speter applies on *_RELAY and in the mailertable entries. Based 451438032Speter on a suggestion by Ribert Kiessling of Easynet. 451538032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 451638032Speter limits the possible domains; this reduces the number of DNS 451738032Speter lookups required to support this feature. For example, 451838032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 451938032Speter to domains under my.site.com. Code contributed by Anthony 452038032Speter Thyssen <anthony@cit.gu.edu.au>. 452138032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 452238032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 452338032Speter of WPI. 452438032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 452538032Speter event you have to define local mailers. Suggested by 452638032Speter Gregory Shapiro of WPI. 452738032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 452838032Speter be misinterpreted as a list:...; syntax. Based on a patch by 452938032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 453038032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 453138032Speter remotely connected. The address host!user was being 453238032Speter converted to host!user@thishost instead of host!user@uurelay. 453338032Speter Problem noted by William Gianopoulos of Raytheon Company. 453438032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 453538032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 453638032Speter "User has moved"; the former wording was confusing if the 453738032Speter new address is still on the local host. Based on a suggestion 453838032Speter by Andreas Luik. 453938032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 454038032Speter However, the class is not pre-initialized to contain root. 454138032Speter Suggested by Gregory Neil Shapiro. 454238032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 454338032Speter Wolfhugel. 454438032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 454538032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 454638032Speter well: this produces a slightly different mailbox format (no 454738032Speter Content-Length: headers), file ownerships and modes are 454838032Speter different (not owned by group mail; mode 600 instead of 660), 454938032Speter and the local mailer flags will have to be tweaked (make them 455038032Speter match bsd4.4) in order to use this mailer. Patches from Paul 455138032Speter Hammann of the Missouri Research and Education Network. 455238032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 455338032Speter was a delivery error, such as if the ownership on the file 455438032Speter was wrong or the mode changed between the initial stat and 455538032Speter the open. Problem reported by William Colburn of the New 455638032Speter Mexico Institute of Mining and Technology. 455738032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 455838032Speter Costales. 455938032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 456038032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 456138032Speter honored. Fix from Michael Scott Shappe. 456238032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 456338032Speter NEW FILES: 456438032Speter src/Makefiles/Makefile.AIX.2 456538032Speter src/Makefiles/Makefile.IRIX.6.2 456638032Speter src/Makefiles/Makefile.maxion 456738032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 456838032Speter src/Makefiles/Makefile.SCO.5.x 456938032Speter src/Makefiles/Makefile.UXPDSV20 457038032Speter mailstats/mailstats.8 457138032Speter praliases/praliases.8 457238032Speter cf/cf/generic-nextstep3.3.mc 457338032Speter cf/feature/genericstable.m4 457438032Speter cf/feature/limited_masquerade.m4 457538032Speter cf/feature/masquerade_entire_domain.m4 457638032Speter cf/feature/virtusertable.m4 457738032Speter cf/ostype/aix2.m4 457838032Speter cf/ostype/altos.m4 457938032Speter cf/ostype/maxion.m4 458038032Speter cf/ostype/solaris2.ml.m4 458138032Speter cf/ostype/uxpds.m4 458238032Speter contrib/re-mqueue.pl 458338032Speter DELETED FILES: 458438032Speter src/Makefiles/Makefile.Solaris 458538032Speter contrib/xla/README 458638032Speter contrib/xla/xla.c 458738032Speter RENAMED FILES: 458838032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 458938032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 459038032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 459138032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 459238032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 459338032Speter 459464562Sgshapiro8.7.6/8.7.3 1996/09/17 459538032Speter SECURITY: It is possible to force getpwuid to fail when writing the 459638032Speter queue file, causing sendmail to fall back to running programs 459738032Speter as the default user. This is not exploitable from off-site. 459838032Speter Workarounds include using a unique user for the DefaultUser 459938032Speter (old u & g options) and using smrsh as the local shell. 460038032Speter SECURITY: fix some buffer overruns; in at least one case this allows 460138032Speter a local user to get root. This is not known to be exploitable 460238032Speter from off-site. The workaround is to disable chfn(1) commands. 460338032Speter 460464562Sgshapiro8.7.5/8.7.3 1996/03/04 460538032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 460638032Speter in some case cause connections to hang or messages to have 460738032Speter extra spaces in odd places. Patch from Eric Wassenaar; 460838032Speter reports from Eric Hall of Chiron Corporation, Stephen 460938032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 461038032Speter and others. 461138032Speter 461264562Sgshapiro8.7.4/8.7.3 1996/02/18 461338032Speter SECURITY: In some cases it was still possible for an attacker to 461438032Speter insert newlines into a queue file, thus allowing access to 461538032Speter any user (except root). 461638032Speter CONFIG: no changes -- it is not a bug that the configuration 461738032Speter version number is unchanged. 461838032Speter 461964562Sgshapiro8.7.3/8.7.3 1995/12/03 462038032Speter Fix botch in name server timeout in RCPT code; this problem caused 462138032Speter two responses in SMTP, which breaks things horribly. Fix 462238032Speter from Gregory Neil Shapiro of WPI. 462338032Speter Verify that L= value on M lines cannot be negative, which could cause 462438032Speter negative array subscripting. Not a security problem since 462538032Speter this has to be in the config file, but it could have caused 462638032Speter core dumps. Pointed out by Bryan Costales. 462738032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 462838032Speter Costales. 462938032Speter PORTABILITY FIXES: 463038032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 463138032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 463238032Speter order. Tweak it to work properly. Based on fixes 463338032Speter from Fletcher Mattox of UTexas and Betty Lee of 463438032Speter Stanford University. 463538032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 463638032Speter Deficiency pointed out by Bryan Costales of ICSI. 463738032Speter 463864562Sgshapiro8.7.2/8.7.2 1995/11/19 463938032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 464038032Speter OperatorChars, and UnixFromLine options. They were not 464138032Speter properly repaired in 8.7.1. 464238032Speter Completely delete the Bcc: header if and only if there are other 464338032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 464438032Speter last being a historic botch, of course). If Bcc: is the 464538032Speter only recipient header in the message, its value is tossed, 464643730Speter but the header name is kept. The old behavior (always keep 464738032Speter the header name and toss the value) allowed primary recipients 464838032Speter to see that a Bcc: went to _someone_. 464938032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 465038032Speter sender to <address> using -f'' syslog messages. Suggested 465138032Speter by Kari Hurtta. 465238032Speter If a sequence or switch map lookup entry gets a tempfail but then 465338032Speter continues on to another map type, but the name is not found, 465438032Speter return a temporary failure from the sequence or switch map. 465538032Speter For example, if hosts search ``dns files'' and DNS fails 465638032Speter with a tempfail, the hosts map will go on and search files, 465738032Speter but if it fails the whole thing should be a tempfail, not 465838032Speter a permanent (host unknown) failure, even though that is the 465938032Speter failure in the hosts.files map. This error caused hard 466038032Speter bounces when it should have requeued. 466138032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 466280785Sgshapiro owned by bar mode 700 and inbox being set-user-id bar stopped 466338032Speter working properly due to excessive paranoia. Pointed out by 466438032Speter John Hawkinson of Panix. 466538032Speter An SMTP RCPT command referencing a host that gave a nameserver 466638032Speter timeout would return a 451 command (8.6 accepted it and 466743730Speter queued it locally). Revert to the 8.6 behavior in order 466838032Speter to simplify queue management for clustered systems. Suggested 466938032Speter by Gregory Neil Shapiro of WPI. The same problem could break 467038032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 467138032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 467238032Speter Infobiogen. 467338032Speter Fix possible buffer overflow in munchstring(). This was not a security 467438032Speter problem because you couldn't specify any argument to this 467538032Speter without first giving up root privileges, but it is still a 467638032Speter good idea to avoid future problems. Problem noted by John 467738032Speter Hawkinson and Sam Hartman of MIT. 467838032Speter ``452 Out of disk space for temp file'' messages weren't being 467938032Speter printed. Fix from David Perlin of Nanosoft. 468043730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 468138032Speter is not set, since this is required to get the actual DSNs 468238032Speter created. Problem pointed out by John Gardiner Myers of CMU. 468338032Speter Log permission problems that cause .forward and :include: files to 468438032Speter be untrusted or ignored on log level 12 and higher. Suggested 468538032Speter by Randy Martin of Clemson University. 468638032Speter Allow user ids in U= clauses of M lines to have hyphens and 468738032Speter underscores. 468838032Speter Fix overcounting of recipients -- only happened when sending to an 468938032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 469038032Speter of Systems and Computer Technology Corporation. 469138032Speter If a message is sent to an address that fails, the error message that 469238032Speter is returned could show some extraneous "success" information 469338032Speter included even if the user did not request success notification, 469438032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 469538032Speter Config files that had no AliasFile definition were defaulting to 469638032Speter using /etc/aliases; this caused problems with nullclient 469738032Speter configurations. Change it back to the 8.6 semantics of 469838032Speter having no local alias file unless it is declared. Problem 469938032Speter noted by Charles Karney of Princeton University. 470038032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 470138032Speter Costales of ICSI. 470238032Speter Map lookups of class "userdb" maps were always case sensitive; they 470338032Speter should be controlled by the -f flag like other maps. Pointed 470438032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 470538032Speter Fix problem that caused some addresses to be passed through ruleset 5 470638032Speter even when they were tagged as "sticky" by prefixing the 470738032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 470838032Speter Technological University. 470938032Speter When converting a message to Quoted-Printable, prevent any lines with 471038032Speter dots alone on a line by themselves. This is because of the 471138032Speter preponderance of broken mailers that still get this wrong. 471238032Speter Code contributed by Per Hedeland of Ericsson. 471338032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 471438032Speter out by Bjart Kvarme of USIT/UiO (Norway). 471538032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 471638032Speter Requested by Allan Johannesen. 471738032Speter Delete check for text format of alias files -- it should be legal 471838032Speter to have the database format of the alias files without the 471938032Speter text version. Problem pointed out by Joe Rhett of Navigist, 472038032Speter Inc. 472138032Speter If "Ot" was specified with no value, the TZ variable was not properly 472238032Speter imported from the environment. Pointed out by Frank Crawford 472338032Speter <frank@ansto.gov.au>. 472438032Speter Some architectures core dumped on "program" maps that didn't have 472538032Speter extra arguments. Patch from Booker C. Bense of Stanford 472638032Speter University. 472738032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 472838032Speter the parent should do this. Fix from Brian Coan of the 472938032Speter Association for Progressive Communications. 473038032Speter If MinQueueAge was set and a message was considered but not run 473138032Speter during a queue run and the Timeout.queuereturn interval was 473238032Speter reached, a "timed out" error message would be returned that 473338032Speter didn't include the failed address (and claimed to be a warning 473438032Speter even though it was fatal). The fix is to not return such 473538032Speter messages until they are actually tried, i.e., in the next 473638032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 473738032Speter SINTEF RUNIT, Oslo. 473838032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 473938032Speter that have the hes_getmailhost() routine.

Bug 478638032Speter pointed out by John Hawkinson of MIT. 478738032Speter Fix strange case of an executable called by a program map that 478838032Speter returns a value but also a non-zero exit status; this 478938032Speter would give contradictory results in the higher level; in 479038032Speter particular, the default clause in the map lookup would be 479138032Speter ignored. Change to ignore the value if the program returns 479238032Speter non-zero exit status. From Tom Moore of AT&T GIS. 479338032Speter Shorten parameters passed to syslog() in some contexts to avoid a 479438032Speter bug in many vendors' implementations of that routine. Although 479538032Speter this isn't really a bug in sendmail per se, and my solution 479638032Speter has to assume that syslog() has at least a 1K buffer size 479738032Speter internally (I know some vendors have shortened this 479838032Speter dramatically -- they're on their own), sendmail is a popular 479938032Speter target. Also, limit the size of %s arguments in sprintf. 480038032Speter These both have possible security implications. Solutions 480138032Speter suggested by Casper Dik of Sun's Network Security Group 480238032Speter (Holland), Mark Seiden, and others. 480338032Speter Fix a problem that might cause a non-standard -B (body type) 480438032Speter parameter to be passed to the next server with undefined 480538032Speter results. This could have security implications. 480638032Speter If a filesystem was at > 100% utilization, the freediskspace() 480738032Speter routine incorrectly returned an error rather than zero. 480838032Speter Problem noted by G. Paul Ziemba of Alantec. 480938032Speter Change MX sort order so that local hostnames (those in $=w) always 481038032Speter sort first within a given preference. This forces the bestmx 481138032Speter map to always return the local host first, if it is included 481238032Speter in the list of highest priority MX records. From K. Robert 481338032Speter Elz. 481438032Speter Avoid some possible null pointer dereferences. Fixes from Randy 481538032Speter Martin <WOLF@CLEMSON.EDU> 481638032Speter When sendmail starts up on systems that have no fully qualified 481738032Speter domain name (FQDN) anywhere in the first matching host map 481838032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 481938032Speter sendmail would sleep to try to find a FQDN, which it really 482038032Speter really needs. This has been changed to fall through to the 482138032Speter next map type if it can't find a FQDN -- i.e., if the hosts 482238032Speter file doesn't have a FQDN, it will try dns even though the 482338032Speter short name was found in /etc/hosts. This is probably a crock, 482438032Speter but many people have hosts files without FQDNs. Remember: 482538032Speter domain names are your friends. 482638032Speter Log a high-priority message if you can't find your FQDN during startup. 482738032Speter Suggested by Simon Barnes of Schlumberger Limited. 482838032Speter When using Hesiod, initialize it early to improve error reporting. 482938032Speter Patch from Don Lewis of Silicon Systems, Inc. 483038032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 483138032Speter connection timeout in the kernel. Add a new "connect" timeout 483238032Speter to limit this time. Defaults to zero (use whatever the 483338032Speter kernel provides). Based on code contributed by J.R. Oldroyd 483438032Speter of TerraNet. 483538032Speter Under some circumstances, a failed message would not be properly 483638032Speter removed from the queue, causing tons of bogus error messages. 483738032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 483838032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 483938032Speter of WPI. 484038032Speter PORTABILITY FIXES: 484138032Speter On IRIX 5.x, there was an inconsistency in the setting 484238032Speter of sendmail.st location. Change the Makefile to 484338032Speter install it in /var/sendmail.st to match the OSTYPE 484438032Speter file and SGI standards.

Suggested by Per Hedeland of Ericsson. 485838032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 485938032Speter otherwise the F=S causes the From_ line to imply that root is 486038032Speter the sender. Problem pointed out by Claude Scarpelli of 486138032Speter Infobiogen (France). 486238032Speter NEW FILES: 486338032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 486438032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 486538032Speter src/Makefiles/Makefile.UXPDS 486638032Speter 486764562Sgshapiro8.7/8.7 1995/09/16 486838032Speter Fix a problem that could cause sendmail to run out of file 486938032Speter descriptors due to a trashed data structure after a 487038032Speter vfork. Fix from Brian Coan of the Institute for 487138032Speter Global Communications. 487238032Speter Change the VRFY response if you have disabled VRFY -- some 487338032Speter people seemed to think that it was too rude. 487438032Speter Avoid reference to uninitialized file descriptor if HASFLOCK 487538032Speter was not defined. This was used "safely" in the sense 487638032Speter that it only did a stat, but it would have set the 487738032Speter map modification time improperly. Problem pointed out 487838032Speter by Roy Mongiovi of Georgia Tech. 487938032Speter Clean up the Subject: line on warning messages and return 488038032Speter receipts so that they don't say "Returned mail:"; this 488138032Speter can be confusing. 488238032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 488338032Speter useful enough to make it worthwhile printing on "-d". 488438032Speter Avoid logging alias statistics every time you read the alias 488538032Speter file on systems with no database method compiled in. 488638032Speter If you have a name with a trailing dot, and you try looking it 488738032Speter up using gethostbyname without the dot (for /etc/hosts 488838032Speter compatibility), be sure to turn off RES_DEFNAMES and 488938032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 489038032Speter Problem noted by Charles Amos of the University of 489138032Speter Maryland. 489238032Speter Don't do timeouts in collect if you are not running SMTP. 489338032Speter There is nothing that says you can't have a long 489438032Speter running program piped into sendmail (possibly via 489538032Speter /bin/mail, which just execs sendmail). Problem reported 489638032Speter by Don "Truck" Lewis of Silicon Systems. 489738032Speter Try gethostbyname() even if the DNS lookup fails iff option I 489838032Speter is not set. This allows you to have hosts listed in 489938032Speter NIS or /etc/hosts that are not known to DNS. It's normally 490038032Speter a bad idea, but can be useful on firewall machines. This 490138032Speter should really be broken out on a separate flag, I suppose. 490238032Speter Avoid compile warnings against BIND 4.9.3, which uses function 490338032Speter prototypes.

From Kyle Jones of UUNET. 490838032Speter SECURITY: avoid denial-of-service attacks possible by destroying 490938032Speter the alias database file by setting resource limits low. 491038032Speter This involves adding two new compile-time options: 491138032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 491238032Speter available) and HASULIMIT (indicating that ulimit(2) support 491338032Speter is available -- the Release 3 form is used). The former 491438032Speter is assumed on BSD-based systems, the latter on System 491538032Speter V-based systems. Attack noted by Phil Brandenberger of 491638032Speter Swarthmore University. 491738032Speter New syntaxes in test (-bt) mode: 491838032Speter ``.Dmvalue'' will define macro "m" to "value". 491938032Speter ``.Ccvalue'' will add "value" to class "c". 492038032Speter ``=Sruleset'' will dump the contents of the indicated 492138032Speter ruleset. 492238032Speter ``=M'' will display the known mailers. 492338032Speter ``-ddebug-spec'' is equivalent to the command-line 492438032Speter -d debug flag. 492538032Speter ``$m'' will print the value of macro $m. 492638032Speter ``$=c'' will print the contents of class $=c. 492738032Speter ``/mx host'' returns the MX records for ``host''. 492838032Speter ``/parse address'' will parse address, returning the value of 492938032Speter crackaddr (essentially, the comment information) 493038032Speter and the parsed address. 493138032Speter ``/try mailer address'' will rewrite address into the form 493238032Speter it will have when presented to the indicated mailer. 493338032Speter ``/tryflags flags'' will set flags used by parsing. The 493438032Speter flags can be `H' for header or `E' for envelope, 493538032Speter and `S' for sender or `R' for recipient. These 493638032Speter can be combined, so `HR' sets flags for header 493738032Speter recipients. 493838032Speter ``/canon hostname'' will try to canonify hostname and 493938032Speter return the result. 494038032Speter ``/map mapname key'' will look up `key' in the indicated 494138032Speter `mapname' and return the result. 494238032Speter Somewhat better handling of UNIX-domain socket addresses -- it 494338032Speter should show the pathname rather than hex bytes. 494438032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 494538032Speter the header for envelope sender information and uses 494638032Speter CR-LF as message terminators. It was thought to be 494738032Speter obsolete (used only for Arpanet NCP protocols), but it 494838032Speter turns out that the UK ``Grey Book'' protocols require 494938032Speter that functionality. 495038032Speter Fix a fix in previous release -- if gethostname and gethostbyname 495138032Speter return a name without dots, and if an attempt to canonify 495238032Speter that name fails, wait one minute and try again. This can 495338032Speter result in an extra 60 second delay on startup if your system 495438032Speter hostname (as returned by hostname(1)) has no dot and no names 495538032Speter listed in /etc/hosts or your NIS map have a dot. 495638032Speter Check for proper domain name on HELO and EHLO commands per 495738032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 495838032Speter of Michigan Technological University. 495938032Speter Relax chownsafe rules slightly -- old version said that if you 496038032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 496138032Speter if fpathconf returned EINVAL or ENOSYS), assume that 496238032Speter chown is not safe. The new version falls back to whether 496338032Speter you are on a BSD system or not. This is important for 496438032Speter SunOS, which apparently always returns one of those 496538032Speter error codes. This impacts whether you can mail to files 496638032Speter or not. 496738032Speter Syntax errors such as unbalanced parentheses in the configuration 496838032Speter file could be omitted if you had "Oem" prior to the 496938032Speter syntax error in the config file. Change to always print 497038032Speter the error message. It was especially weird because it 497138032Speter would cause a "warning" message to be sent to the Postmaster 497238032Speter for every message sent (but with no transcript). Problem 497338032Speter noted by Gregory Paris of Motorola. 497438032Speter Rewrite collect and putbody to handle full 8-bit data, including 497538032Speter zero bytes.

This is to handle the 504438032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 504538032Speter assume that ``group name:'' is a comment on the first 504638032Speter address and the ``;'' is a comment on the last address). 504738032Speter This requires config file support to get right. It does 504838032Speter understand that :: is NOT this syntax, and can be turned 504938032Speter off completely by setting the ColonOkInAddresses option. 505038032Speter Level 6 config files added with new mailer flags: 505138032Speter A Addresses are aliasable. 505238032Speter i Do udb rewriting on envelope as well as header 505338032Speter sender lines. Applies to the from address mailer 505438032Speter flags rather than the recipient mailer flags. 505538032Speter j Do udb rewriting on header recipient addresses. 505638032Speter Applies to the sender mailer flags rather than the 505738032Speter recipient mailer flags. 505838032Speter k Disable check for loops when doing HELO command. 505938032Speter o Always run as the mail recipient, even on local 506038032Speter delivery. 506138032Speter w Check for an /etc/passwd entry for this user. 506238032Speter 5 Pass addresses through ruleset 5. 506338032Speter : Check for :include: on this address. 506438032Speter | Check for |program on this address. 506538032Speter / Check for /file on this address. 506638032Speter @ Look up sender header addresses in the user 506738032Speter database. Applies to the mailer flags for the 506838032Speter mailer corresponding to the envelope sender 506938032Speter address, rather than to recipient mailer flags. 507038032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 507138032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 507238032Speter mailers, and the ColonOkInAddresses option. 507338032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 507438032Speter John Beck of Hewlett-Packard, who generously contributed 507538032Speter their implementation to me, which I then didn't use (see 507638032Speter mime.c for an explanation of why). This adds the 507738032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 507838032Speter to control handling of 8-bit data. These have to cope with 507938032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 508038032Speter 8-bit data that is entered without declaring it as 8-bit 508138032Speter MIME -- technically this is illegal according to the 508238032Speter specs) and labelled 8-bit data (that is, it was declared 508338032Speter as 8BITMIME in the ESMTP session or by using the 508438032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 508538032Speter set then 8-bit data is sent to non-8BITMIME machines 508638032Speter instead of converting to 7 bit (essentially using 508738032Speter just-send-8 semantics). The values for EightBitMode are: 508838032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 508938032Speter any necessary conversion of 8BITMIME to 7BIT 509038032Speter (essentially, the full MIME option). 509138032Speter p pass unlabelled 8-bit input, but convert labelled 509238032Speter 8BITMIME input to 7BIT as required (default). 509338032Speter s strict adherence: reject unlabelled 8-bit input, 509438032Speter convert 8BITMIME to 7BIT as required. The F=8 509538032Speter flag is ignored. 509638032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 509738032Speter the setting of F=8. 509838032Speter Add new internal class 'n', which is the set of MIME Content-Types 509938032Speter which can not be 8 to 7 bit encoded because of other 510038032Speter considerations. Types "multipart/*" and "message/*" are 510138032Speter never directly encoded (although their components can be). 510238032Speter Add new internal class 's', which is the set of subtypes of the 510338032Speter MIME message/* content type that can be treated as though 510438032Speter they are an RFC822 message. It is predefined to have 510538032Speter "rfc822". Suggested By Kari Hurtta. 510638032Speter Add new internal class 'e'. This is the set of MIME 510738032Speter Content-Transfer-Encodings that can be converted to 510838032Speter a seven bit format (Quoted-Printable or Base64). It is 510938032Speter preinitialized to contain "7bit", "8bit", and "binary". 511038032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 511138032Speter short name) to set the default character set to use in the 511238032Speter Content-Type: header when doing encoding of an 8-bit message 511338032Speter which isn't marked as MIME into MIME format. If the C= 511438032Speter parameter is set on the Envelope From address, use that as 511538032Speter the default encoding; else use the DefaultCharSet option. 511638032Speter If neither is set, it defaults to "unknown-8bit" as 511738032Speter suggested by RFC 1428 section 3. 511838032Speter Allow ``U=user:group'' field in mailer definition to set a default 511938032Speter user and group that a mailer will be executed as. This 512038032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 512138032Speter also set, it is the uid/gid that will always be used (that 512238032Speter is, the controlling address is ignored). The values may be 512338032Speter numeric or symbolic; if only a symbolic user is given (no 512438032Speter group) that user's default group in the passwd file is used 512538032Speter as the group. Based on code donated by Chip Rosenthal of 512638032Speter Unicom. 512738032Speter Allow `u' option to also accept user:group as a value, in the same 512838032Speter fashion as the U= mailer option. 512938032Speter Add the symbolic time zone name in the Arpanet format dates (as 513038032Speter a comment). This adds a new compile-time configuration 513138032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 513238032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 513338032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 513438032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 513538032Speter timezone()), or TZ_NONE (don't include the comment). Code 513638032Speter from Chip Rosenthal. 513738032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 513838032Speter For example, 513938032Speter O Timeout.helo = 2m 514038032Speter There are also two new suboptions "queuereturn" and 514138032Speter "queuewarn"; these subsume the old T option. Thus, to 514238032Speter set them both the preferred new syntax is 514338032Speter O Timeout.queuereturn = 5d 514438032Speter O Timeout.queuewarn = 4h 514538032Speter Sort queue by host name instead of by message priority if the 514638032Speter QueueSortOrder option (no short name) is set is set to 514738032Speter ``host''. This makes better use of the connection cache, 514838032Speter but may delay more ``interactive'' messages behind large 514938032Speter backlogs under some circumstances. This is probably a 515038032Speter good option if you have high speed links or don't do lots 515138032Speter of ``batch'' messages, but less good if you are using 515238032Speter something like PPP on a 14.4 modem. Based on code 515338032Speter contributed by Roy Mongiovi of Georgia Tech (my main 515438032Speter contribution was to make it configurable). 515538032Speter Save i-number of df file in qf file to simplify rebuilding of queue 515638032Speter after disastrous disk crash. Suggested by Kyle Jones of 515738032Speter UUNET; closely based on code from KJS DECWRL code written 515838032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 515938032Speter are NOT back compatible with 8.6 -- that is, you can convert 516038032Speter from 8.6 to 8.7, but not the other direction. 516138032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 516238032Speter route-addrs in envelopes; this is because in some cases 516338032Speter they can be sent to the shell, which interprets them as 516438032Speter I/O redirection. 516538032Speter Don't include error file (option E) with return-receipts; this 516638032Speter can be confusing. 516738032Speter Don't send "Warning: cannot send" messages to owner-* or 516838032Speter *-request addresses. Suggested by Christophe Wolfhugel 516938032Speter of the Institut Pasteur, Paris. 517038032Speter Allow -O command line flag to set long form options. 517138032Speter Add "MinQueueAge" option to set the minimum time between attempts 517238032Speter to run the queue. For example, if the queue interval 517338032Speter (-q value) is five minutes, but the minimum queue age 517438032Speter is fifteen minutes, jobs won't be tried more often than 517538032Speter once every fifteen minutes. This can be used to give 517638032Speter you more responsiveness if your delivery mode is set to 517738032Speter queue-only. 517838032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 517938032Speter :include: and .forward files. 518038032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 518138032Speter key field name, the value field name, and the field 518238032Speter delimiter. The field delimiter can be a single character 518338032Speter or the sequence "\t" or "\n" for tab or newline. 518438032Speter These are for use by NIS+ and similar access methods. 518538032Speter Change maps to always strip quotes before lookups; the -q flag 518643730Speter turns off this behavior. Suggested by Motonori Nakamura. 518738032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 518838032Speter key and value field names respectively. Code donated by 518938032Speter Sun Microsystems. 519038032Speter Add "hesiod" map class. The "file name" is used as the 519138032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 519238032Speter first value found for the match. Code donated by Scott 519338032Speter Hutton of Indiana University. 519438032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 519538032Speter specify the name of the property that is searched as the 519638032Speter key and a -v flag to specify the name of the property that 519738032Speter is returned as the value (defaults to "members"). The 519838032Speter default map is "/aliases". Some code based on code 519938032Speter contributed by Robert La Ferla of Hot Software. 520038032Speter Add "text" map class. This does slow, linear searches through 520138032Speter text files. The -z flag specifies a column delimiter 520238032Speter (defaults to any sequence of white space), the -k flag 520338032Speter sets the key column number, and the -v flag sets the 520438032Speter value column number. Lines beginning with `#' are treated 520538032Speter as comments. 520638032Speter Add "program" map class to execute arbitrary programs. The search 520738032Speter key is presented as the last argument; the output is one 520838032Speter line read from the programs standard output. Exit statuses 520938032Speter are from sysexits.h. 521038032Speter Add "sequence" map class -- searches maps in sequence until it 521138032Speter finds a match. For example, the declarations: 521238032Speter Kmap1 ... 521338032Speter Kmap2 ... 521438032Speter Kmapseq sequence map1 map2 521538032Speter defines a map "mapseq" that first searches map1; if the 521638032Speter value is found it is returned immediately, otherwise 521738032Speter map2 is searched and the value returned. 521838032Speter Add "switch" map class. This is much like "sequence" except that 521938032Speter the ordering is fetched from an external file, usually 522038032Speter the system service switch. The parameter is the name of 522138032Speter the service to switch on, and the maps that it will use 522238032Speter are the name of the switch map followed by ".service_type". 522338032Speter For example, if the declaration of the map is 522438032Speter Ksample switch hosts 522538032Speter and the system service switch specifies that hosts are 522638032Speter looked up using dns and nis in that order, then this is 522738032Speter equivalent to 522838032Speter Ksample sequence sample.dns sample.nis 522938032Speter The subordinate maps (sample.*) must already be defined. 523038032Speter Add "user" map class -- looks up users using getpwnam. Takes a 523138032Speter "-v field" flag on the definition that tells what passwd 523238032Speter entry to return -- legal values are name, passwd, uid, gid, 523338032Speter gecos, dir, and shell. Generally expected to be used with 523438032Speter the -m (matchonly) flag. 523538032Speter Add "bestmx" map class -- returns the best MX value for the host 523638032Speter listed as the value. If there are several "best" MX records 523738032Speter for this host, one will be chosen at random. 523838032Speter Add "userdb" map class -- looks up entries in the user database. 523938032Speter The "file name" is actually the tag that will be used, 524038032Speter typically "mailname". If there are multiple entries 524138032Speter matching the name, the one chosen is undefined. 524238032Speter Add multiple queue timeouts (both return and warning). These are 524338032Speter set by the Precedence: or Priority: header fields to one of 524438032Speter three values. If a Priority: is set and has value "normal", 524564562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 524638032Speter used. If no priority is set, the Precedence: is consulted; 524738032Speter if negative, non-urgent timeouts are used; if greater than 524838032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 524938032Speter are used. The timeouts are set by setting the six timeouts 525038032Speter queue{warn,return}.{urgent,normal,non-urgent}. 525138032Speter Fix problem when a mail address is resolved to a $#error mailer 525238032Speter with a temporary failure indication; it works in SMTP, 525338032Speter but when delivering locally the mail is silently discarded. 525438032Speter This patch, from Kyle Jones of UUNET, bounces it instead 525538032Speter of queueing it (queueing is very hard). 525638032Speter When using /etc/hosts or NIS-style lookups, don't assume that 525738032Speter the first name in the list is the best one -- instead, 525838032Speter search for the first one with a dot. For example, if 525938032Speter an /etc/hosts entry reads 526038032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 526138032Speter this change will use the second name as the canonical 526238032Speter machine name instead of the initial, unqualified name. 526338032Speter Change dequote map to replace spaces in quoted text with a value 526438032Speter indicated by the -s flag on the dequote map definition. 526538032Speter For example, ``Mdequote dequote -s_'' will change 526638032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 526738032Speter quoted (because of the space character). Suggested by Dan 526838032Speter Oscarsson for use in X.400 addresses. 526938032Speter Implement long macro names as ${name}; long class names can 527038032Speter be similarly referenced as $={name} and $~{name}. 527138032Speter Definitions are (e.g.) ``D{name}value''. Names that have 527238032Speter a leading lower case letter or punctuation characters are 527338032Speter reserved for internal use by sendmail; i.e., config files 527438032Speter should use names that begin with a capital letter. Based 527538032Speter on code contributed by Dan Oscarsson. 527638032Speter Fix core dump if getgrgid returns a null group list (as opposed 527738032Speter to an empty group list, that is, a pointer to a list 527838032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 527938032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 528038032Speter failed, it called syserr which called newstr which called 528138032Speter xalloc.... The newstr is now avoided for "panic" messages. 528238032Speter Reported by Stuart Kemp of James Cook University. 528338032Speter Improve connection cache timeouts; previously, they were not even 528438032Speter checked if you were delivering to anything other than an 528538032Speter IPC-connected host, so a series of (say) local mail 528638032Speter deliveries could cause cached connections to be open 528738032Speter much longer than the specified timeout. 528838032Speter If an incoming message exceeds the maximum message size, stop 528938032Speter writing the incoming bytes to the queue data file, since 529038032Speter this can fill your mqueue partition -- this is a possible 529138032Speter denial-of-service attack. 529238032Speter Don't reject all numeric local user names unless HESIOD is 529338032Speter defined. It turns out that Posix allows all-numeric 529438032Speter user names. Fix from Tony Sanders of BSDI. 529538032Speter Add service switch support. If the local OS has a service 529638032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 529738032Speter on DEC systems) that will be used; otherwise, it falls back 529838032Speter to using a local mechanism based on the ServiceSwitchFile 529938032Speter option (default: /etc/service.switch). For example, if the 530038032Speter service switch lists "files" and "nis" for the aliases 530138032Speter service, that will be the default lookup order. the "files" 530238032Speter ("local" on DEC) service type expands to any alias files 530338032Speter you listed in the configuration file, even if they aren't 530438032Speter actually file lookups. 530538032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 530638032Speter variable which tells whether or not DNS should be considered 530738032Speter canonical. This is now determined based on whether or not 530838032Speter "dns" is in the service list for "hosts". 530938032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 531038032Speter Status Notifications). DSN notifications override 531138032Speter Return-Receipt-To: headers, which are bogus anyhow -- 531238032Speter support for them has been removed. 531338032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 531438032Speter definitions to define the types used in DSN returns for 531538032Speter MTA names, addresses, and diagnostics respectively. 531638032Speter Extend heuristic to force running in ESMTP mode to look for the 531738032Speter five-character string "ESMTP" anywhere in the 220 greeting 531838032Speter message (not just the second line). This is to provide 531938032Speter better compatibility with other ESMTP servers. 532038032Speter Print sequence number of job when running the queue so you can 532138032Speter easily see how much progress you have made. Suggested 532238032Speter by Peter Wemm of DIALix. 532338032Speter Map newlines to spaces in logged message-ids; some versions of 532438032Speter syslog truncate the rest of the line after newlines. 532538032Speter Suggested by Fletcher Mattox of U. Texas. 532638032Speter Move up forking for job runs so that if a message is split into 532738032Speter multiple envelopes you don't get "fork storms" -- this 532838032Speter also improves the connection cache utilization. 532938032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 533038032Speter the purposes of refusing to send error returns. Suggested 533138032Speter by Motonori Nakamura of Ritsumeikan University. 533238032Speter Relax rules on when a file can be written when referenced from 533338032Speter the aliases file: use the default uid/gid instead of the 533438032Speter real uid/gid. This allows you to create a file owned by 533538032Speter and writable only by the default uid/gid that will work 533680785Sgshapiro all the time (without having the set-user-id bit set). Change 533738032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 533838032Speter Microsystems. 533938032Speter Add "DialDelay" option (no short name) to provide an "extra" 534038032Speter delay for dial on demand systems. If this is non-zero 534138032Speter and a connect fails, sendmail will wait this long and 534238032Speter then try again. If it takes longer than the kernel 534338032Speter timeout interval to establish the connection, this 534438032Speter option can give the network software time to establish 534538032Speter the link. The default units are seconds. 534638032Speter Move logging of sender information to be as early as possible; 534738032Speter previously, it could be delayed a while for SMTP mail 534838032Speter sent to aliases. Suggested by Brad Knowles of the 534938032Speter Defense Information Systems Agency. 535038032Speter Call res_init() before setting RES_DEBUG; this is required by 535138032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 535238032Speter the National Computer Security Center. 535338032Speter Add xdelay= field in logs -- this is a transaction delay, telling 535438032Speter you how long it took to deliver to this address on the 535538032Speter last try. It is intended to be used for sorting mailing 535638032Speter lists to favor "quick" addresses. Provided for use by 535738032Speter the mailprio scripts (see below). 535838032Speter If a map cannot be opened, and that map is non-optional, and 535938032Speter an address requires that map for resolution, queue the 536038032Speter map instead of bouncing it. This involves creating a 536138032Speter pseudo-class of maps called "bogus-map" -- if a required 536238032Speter map cannot be opened, the class is changed to bogus-map; 536338032Speter all queries against bogus-map return "tempfail". The 536438032Speter bogus-map class is not directly accessible. A sample 536538032Speter implementation was donated by Jem Taylor of Glasgow 536638032Speter University Computing Service. 536738032Speter Fix a possible core dump when mailing to a program that talks 536838032Speter SMTP on its standard input. Fix from Keith Moore of 536938032Speter the University of Kentucky. 537038032Speter Make it possible to resolve filenames to $#local $: @ /filename; 537138032Speter previously, the "@" would cause it to not be recognized 537238032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 537338032Speter Accept a -1 signal to re-exec the daemon. This only works if 537438032Speter argv[0] is a full path to sendmail. 537538032Speter Fix bug in "addr=..." field in O option on little-endian machines 537638032Speter -- the network number wasn't being converted to network 537738032Speter byte order. Patch from Kurt Lidl of Pix Technologies 537838032Speter Corporation. 537938032Speter Pre-initialize the resolver early on; this is to avoid a bug with 538038032Speter BIND 4.9.3 that can cause the _res.retry field to get 538138032Speter reset to zero, causing all name server lookups to time 538238032Speter out. Fix from Matt Day of Artisoft. 538338032Speter Restore T line (trusted users) in config file -- but instead of 538438032Speter locking out the -f flag, they just tell whether or not 538538032Speter an X-Authentication-Warning: will be added. This really 538638032Speter just creates new entries in class 't', so "Ft/file/name" 538738032Speter can be used to read trusted user names from a file. 538838032Speter Trusted users are also allowed to execute programs even 538938032Speter if they have a shell that isn't in /etc/shells. 539038032Speter Improve NEWDB alias file rebuilding so it will create them 539138032Speter properly if they do not already exist. This had been 539238032Speter a MAYBENEXTRELEASE feature in 8.6.9. 539338032Speter Check for @:@ entry in NIS maps before starting up to avoid 539438032Speter (but not prevent, sigh) race conditions. This ought to 539538032Speter be handled properly in ypserv, but isn't. Suggested by 539638032Speter Michael Beirne of Motorola. 539738032Speter Refuse connections if there isn't enough space on the filesystem 539838032Speter holding the queue. Contributed by Robert Dana of Wolf 539938032Speter Communications. 540038032Speter Skip checking for directory permissions in the path to a file 540138032Speter when checking for file permissions iff setreuid() 540238032Speter succeeded -- it is unnecessary in that case. This avoids 540338032Speter significant performance problems when looking for .forward 540438032Speter files. Based on a suggestion by Win Bent of USC. 540538032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 540638032Speter arbitrary ruleset number assigned or "Sname = integer" 540738032Speter to assign a specific ruleset number. Reference is 540838032Speter $>name_or_number. Names can be composed of alphas, digits, 540938032Speter underscore, or hyphen (first character must be non-numeric). 541038032Speter Allow -o flag on AliasFile lines to make the alias file optional. 541138032Speter From Bryan Costales of ICSI. 541238032Speter Add NoRecipientAction option to handle the case where there is 541338032Speter no legal recipient header in the message. It can take 541438032Speter on values: 541538032Speter None Leave the message as is. The 541638032Speter message will be passed on even 541738032Speter though it is in technically 541838032Speter illegal syntax. 541938032Speter Add-To Add a To: header with any 542038032Speter recipients that it can find from 542138032Speter the envelope. This risks exposing 542238032Speter Bcc: recipients. 542338032Speter Add-Apparently-To Add an Apparently-To: header. This 542438032Speter has almost no redeeming social value, 542538032Speter and is provided only for back 542638032Speter compatibility. 542738032Speter Add-To-Undisclosed Add a header reading 542838032Speter To: undisclosed-recipients:; 542938032Speter which will have the effect of 543038032Speter making the message legal without 543138032Speter exposing Bcc: recipients. 543238032Speter Add-Bcc To add an empty Bcc: header. 543338032Speter There is a chance that mailers down 543438032Speter the line will delete this header, 543538032Speter which could cause exposure of Bcc: 543638032Speter recipients. 543738032Speter The default is NoRecipientAction=None. 543838032Speter Truncate (rather than delete) Bcc: lines in the header. This 543938032Speter should prevent later sendmails (at least, those that don't 544038032Speter themselves delete Bcc:) from considering this message to 544138032Speter be non-conforming -- although it does imply that non-blind 544238032Speter recipients can see that a Bcc: was sent, albeit not to whom. 544338032Speter Add SafeFileEnvironment option. If declared, files named as delivery 544438032Speter targets must be regular files in addition to the regular 544538032Speter checks. Also, if the option is non-null then it is used as 544638032Speter the name of a directory that is used as a chroot(2) 544738032Speter environment for the delivery; the file names listed in an 544838032Speter alias or forward should include the name of this root. 544938032Speter For example, if you run with 545038032Speter O SafeFileEnvironment=/arch 545138032Speter then aliases should reference "/arch/rest/of/path". If a 545238032Speter value is given, sendmail also won't try to save to 545338032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 545438032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 545538032Speter Support -A flag for alias files; this will comma concatenate like 545638032Speter entries. For example, given the aliases: 545738032Speter list: member1 545838032Speter list: member2 545938032Speter and an alias file declared as: 546038032Speter OAhash:-A /etc/aliases 546138032Speter the final alias inserted will be "list: member1,member2"; 546238032Speter without -A you will get an error on the second and subsequent 546338032Speter alias for "list". Contributed by Bryan Costales of ICSI. 546438032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 546538032Speter Fix a problem that could cause very long addresses to core dump in 546638032Speter some special circumstances. Problem pointed out by Allan 546738032Speter Johannesen. 546838032Speter (Internal change.) Change interface to expand() (macro expansion) 546938032Speter to be simpler and more consistent. 547038032Speter Delete check for funny qf file names. This didn't really give 547138032Speter any extra security and caused some people some problems. 547238032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 547338032Speter at compile time.) Suggested by Kyle Jones of UUNET. 547438032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 547538032Speter merge with DSN code; this is simpler and more consistent. 547638032Speter This may affect some people who have written their own 547738032Speter checkcompat() routine. 547838032Speter (Internal change.) Eliminate `D' line in qf file. The df file 547938032Speter is now assumed to be the same name as the qf file (with 548038032Speter the `q' changed to a `d', of course). 548138032Speter Avoid forking for delivery if all recipient mailers are marked as 548238032Speter "expensive" -- this can be a major cost on some systems. 548338032Speter Essentially, this forces sendmail into "queue only" mode 548438032Speter if all it is going to do is queue anyway. 548538032Speter Avoid sending a null message in some rather unusual circumstances 548638032Speter (specifically, the RCPT command returns a temporary 548738032Speter failure but the connection is lost before the DATA 548838032Speter command). Fix from Scott Hammond of Secure Computing 548938032Speter Corporation. 549038032Speter Change makesendmail to use a somewhat more rational naming scheme: 549138032Speter Makefiles and obj directories are named $os.$rel.$arch, 549238032Speter where $os is the operating system (e.g., SunOS), $rel is 549338032Speter the release number (e.g., 5.3), and $arch is the machine 549438032Speter architecture (e.g., sun4). Any of these can be omitted, 549538032Speter and anything after the first dot in a release number can 549638032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 549738032Speter version used $os.$arch.$rel and was rather less general. 549838032Speter Change makesendmail to do a "make depend" in the target directory 549938032Speter when it is being created. This involves adding an empty 550038032Speter "depend:" entry in most Makefiles. 550138032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 550238032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 550338032Speter of the Finnish Meteorological Institute. 550438032Speter Fix problem that could cause multiple responses to DATA command 550538032Speter on header syntax errors (e.g., lines beginning with colons). 550638032Speter Problem noted by Jens Thomassen of the University of Oslo. 550738032Speter Don't let null bytes in headers cause truncation of the rest of 550838032Speter the header. 550938032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 551038032Speter Increase timeouts on message data puts to allow time for receivers 551138032Speter to canonify addresses in headers on the fly. This is still 551238032Speter a rather ugly heuristic. From Motonori Nakamura. 551338032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 551438032Speter records are not used when canonifying names, and when MX 551538032Speter lookups are done for addressing they must be fully 551638032Speter qualified. This is useful if you have a wildcard MX record, 551738032Speter although it may cause other problems. In general, don't use 551838032Speter wildcard MX records. Patch from Motonori Nakamura. 551938032Speter Eliminate default two-line SMTP greeting message. Instead of 552038032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 552138032Speter is added between the first and second word of the first 552238032Speter line of the greeting message (i.e., immediately after the 552338032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 552438032Speter compile flag. Old sendmails won't see the ESMTP, but that's 552538032Speter acceptable because SIZE was the only useful extension that 552638032Speter old sendmails understand. 552738032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 552838032Speter invoked state dumps. From Masaharu Onishi. 552938032Speter Allow on-line comments in .forward and :include: files; they are 553038032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 553138032Speter is a space or a tab. This is intended for native 553238032Speter representation of non-ASCII sets such as Japanese, where 553338032Speter existing encodings would be unreadable or would lose 553438032Speter data -- for example, 553538032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 553638032Speter (romanized/less information) 553738032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 553838032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 553938032Speter (with MIME encoding, not human readable) 554038032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 554138032Speter (native encoding with ISO-2022-JP) 554238032Speter The last form is human readable in the Japanese environment. 554338032Speter Based on a fix from (surprise!) Motonori Nakamura. 554438032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 554538032Speter messages to that host; these are most frequently associated 554638032Speter with addresses rather than the host, with the exception of 554738032Speter 421 (service shutting down). The effect was to cause queues 554838032Speter to sometimes take an excessive time to flush. Reported by 554938032Speter Robert Sargent of Southern Geographics Technologies and 555038032Speter Eric Prestemon of American University. 555138032Speter Add Nice=N mailer option to set the niceness at which a mailer will 555238032Speter run. This is actually a relative niceness (that is, an 555338032Speter increment on the background value). 555438032Speter Log queue runs that are skipped due to high loads. They are logged 555538032Speter at LOG_INFO priority iff the log level is > 8. Contributed 555638032Speter by Bruce Nagel of Data General. 555738032Speter Allow the error mailer to accept a DSN-style error status code 555838032Speter instead of an sysexits status code in the host part. 555938032Speter Anything with a dot will be interpreted as a DSN-style code. 556038032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 556138032Speter to encode characters that might be munged by an EBCDIC system 556238032Speter in addition to the set required by RFC 1521. The additional 556338032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 556438032Speter (Think of "IBM 360" as the mnemonic for this flag.) 556538032Speter Change check for mailing to files to look for a pathname of [FILE] 556638032Speter rather than looking for the mailer named *file*. The mapping 556738032Speter of leading slashes still goes to the *file* mailer. This 556838032Speter allows you to implement the *file* mailer as a separate 556938032Speter program, for example, to insert a Content-Length: header 557038032Speter or do special security policy. However, note that the usual 557138032Speter initial checking for the file permissions is still done, and 557238032Speter the program in question needs to be very careful about how 557338032Speter it does the file write to avoid security problems. 557438032Speter Be able to read ~root/.forward even if the path isn't accessible to 557538032Speter regular users. This is disrecommended because sendmail 557638032Speter sometimes does not run as root (e.g., when an unsafe option 557738032Speter is specified on the command line), but should otherwise be 557838032Speter safe because .forward files must be owned by the user for 557938032Speter whom mail is being forwarded, and cannot be a symbolic link. 558038032Speter Suggested by Forrest Aldrich of Wang Laboratories. 558138032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 558238032Speter file. This is used for canonifying hostnames when the 558338032Speter service type is "files". 558438032Speter Implement programs on F (read class from file) line. The syntax is 558538032Speter Fc|/path/to/program to read the output from the program 558638032Speter into class "c". 558738032Speter Probe the network interfaces to find alternate names for this 558838032Speter host. Requires the SIOCGIFCONF ioctl call. Code 558938032Speter contributed by SunSoft. 559038032Speter Add "E" configuration line to set or propagate environment 559138032Speter variables into children. "E<envar>" will propagate 559238032Speter the named variable from the environment when sendmail 559338032Speter was invoked into any children it calls; "E<envar>=<value>" 559438032Speter sets the named variable to the indicated value. Any 559538032Speter variables not explicitly named will not be in the child 559638032Speter environment. However, sendmail still forces an 559738032Speter "AGENT=sendmail" environment variable, in part to enforce 559838032Speter at least one environment variable, since many programs and 559938032Speter libraries die horribly if this is not guaranteed. 560038032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 560138032Speter alias databases -- new algorithm looks for the substring 560238032Speter "/yp/" in the file name. This is more portable and involves 560338032Speter less overhead. Suggested by Motonori Nakamura. 560438032Speter Dynamically allocate the queue work list so that you don't lose 560538032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 560638032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 560738032Speter should not need to be changed) and the MaxQueueRunSize option, 560838032Speter which is the absolute maximum number of jobs that will ever 560938032Speter be handled in a single queue run. Based on code contributed 561038032Speter by Brian Coan of the Institute for Global Communications. 561138032Speter Log message when a message is dropped because it exceeds the maximum 561238032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 561338032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 561438032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 561538032Speter of Mark G. Thomas Consulting. 561638032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 561738032Speter OS-dependent defines). The old semantic of -d0.1 to not 561838032Speter run the daemon in background has been moved to -d99.100, 561938032Speter and the old 52.5 flag (to avoid disconnect() from closing 562038032Speter all output files) has been moved to 52.100. This makes 562138032Speter things more consistent (flags below .100 don't change 562238032Speter semantics) and separates out the backgrounding so that 562338032Speter it doesn't happen automatically on other unrelated debugging 562438032Speter flags. 562538032Speter If -t is used but no addresses are found in the header, give an 562638032Speter error message rather than just doing nothing. Fix from 562738032Speter Motonori Nakamura. 562838032Speter On systems (like SunOS) where the effective gid is not necessarily 562938032Speter included in the group list returned by getgroups(), the 563038032Speter `restrictmailq' option could sometimes cause an authorized 563138032Speter user to not be able to use `mailq'. Fix from Charles Hannum 563238032Speter of MIT. 563338032Speter Allow symbolic service names for [IPC] mailers. Suggested by 563438032Speter Gerry Magennis of Logica International. 563538032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 563638032Speter when running DNS. For example, if the name FTP.Foo.ORG is 563738032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 563838032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 563938032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 564038032Speter This is technically illegal under RFC 822 and 1123, but the 564138032Speter IETF is moving toward legalizing it. Note that turning on 564238032Speter this option is not sufficient to guarantee that a downstream 564338032Speter neighbor won't rewrite the address for you. 564438032Speter Add "-m" flag to makesendmail script -- this tells you what object 564538032Speter directory and Makefile it will use, but doesn't actually do 564638032Speter the make. 564738032Speter Do some additional checking on the contents of the qf file to try 564838032Speter to detect attacks against the qf file. In particular, 564938032Speter abort on any line beginning "From ", and add an "end of 565038032Speter file" line -- any data after that line is prohibited. 565138032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 565238032Speter choices. This can be overridden in the Makefile by using 565338032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 565438032Speter (to the extent that we know it) or by defining 565538032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 565638032Speter sendmail 8 to have more consistent installation instructions. 565738032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 565838032Speter of Sun Microsystems. 565938032Speter Improved symbol table hash function from Eric Wassenaar. This one 566038032Speter is at least 50% faster. 566138032Speter Fix problem that didn't notice that timeout on file open was a 566238032Speter transient error. Fix from Larry Parmelee of Cornell 566338032Speter University. 566438032Speter Allow comments (lines beginning with a `#') in files read for 566538032Speter classes. Suggested by Motonori Nakamura. 566638032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 566738032Speter of dropping out entirely. This makes testing some of the 566838032Speter name server lookups easier to deal with when there are 566938032Speter hung servers. From Motonori Nakamura. 567038032Speter Add new ${opMode} macro that is set to the current operation mode 567138032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 567238032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 567338032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 567438032Speter Kind of like queue-only mode (Odq) except it tries to avoid 567538032Speter any external service requests; for dial-on-demand hosts that 567638032Speter want to minimize DNS lookups when mail is being queued. For 567738032Speter this to work you will also have to make sure that gethostbyname 567838032Speter of your local host name does not do a DNS lookup. 567938032Speter Improved handling of "out of space" conditions from John Myers of 568038032Speter Carnegie Mellon. 568138032Speter Improved security for mailing to files on systems that have fchmod(2) 568238032Speter support. 568338032Speter Improve "cannot send message for N days" message -- now says "could 568438032Speter not send for past N days". Suggested by Tom Moore of AT&T 568538032Speter Global Information Solutions. 568638032Speter Less misleading Subject: line on messages sent to postmaster only. 568738032Speter From Motonori Nakamura. 568838032Speter Avoid duplicate error messages on bad command line flags. From 568938032Speter Motonori Nakamura. 569038032Speter Better error message for case where ruleset 0 falls off the end 569138032Speter or otherwise does not resolve to a canonical triple. 569238032Speter Fix a problem that could cause multiple bounce messages if a bad 569338032Speter address was sent along with a good address to an SMTP 569438032Speter site where that SMTP site returned a 4yz code in response 569538032Speter to the final dot of the data. Problem reported by David 569638032Speter James of British Telecom. 569738032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 569838032Speter from Alexander Dupuy of System Management ARTS. 569938032Speter Delete duplicates in MX lists -- believe it or not, there are sites 570038032Speter that list the same host twice in an MX list. This deletion 570138032Speter only works on adjacent preferences, so an MX list that 570238032Speter had A=5, B=10, A=15 would leave both As, but one that had 570338032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 570438032Speter just in case there is something weird I haven't thought of. 570538032Speter Suggested by Barry Shein of Software Tool & Die. 570638032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 580138032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 580238032Speter University of Brno (Czech Republic). 580338032Speter KSR OS 1.2.2 support from Todd Miller of the University 580438032Speter of Colorado. 580538032Speter UX4800 support from Kazuhisa Shimizu of NEC. 580638032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 580738032Speter in type ``btree'' maps. The semantics of this are undefined 580838032Speter for regular maps, but it can be useful for the user database. 580938032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 581038032Speter lookups while the rebuild is going on. There is a race 581138032Speter condition between the open(... O_TRUNC ...) and the lock 581238032Speter on the file, but it should be quite small. 581338032Speter SMRSH: sendmail restricted shell added to the release. This can 581438032Speter be used as an alternative to /bin/sh for the "prog" mailer, 581538032Speter giving the local administrator more control over what 581638032Speter programs can be run from sendmail. 581738032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 581838032Speter part of the release proper, and isn't fully supported; in 581938032Speter particular, it does not run on System V based systems and 582038032Speter never will. 582138032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 582238032Speter to allow rmail to compile on systems that don't have 582338032Speter function prototypes and systems that don't have snprintf. 582438032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 582538032Speter lists by transaction delay times so that addresses that 582638032Speter respond quickly get sent first. This is to prevent very 582738032Speter sluggish servers from delaying other peoples' mail. 582838032Speter Contributed by Tony Sanders of BSDI. 582938032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 583038032Speter of BSDI. This has a lot of comments to help people out. 583138032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 583238032Speter put this on the m4 command line. On GNU m4 (which 583338032Speter supports the __file__ primitive) you can run m4 in an 583438032Speter arbitrary directory -- use either: 583538032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 583638032Speter or 583738032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 583838032Speter On other versions of m4 that don't support __file__, you 583938032Speter can use: 584038032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 584138032Speter (Note the trailing slash on the _CF_DIR_ definition.) 584238032Speter Old versions of m4 will default to _CF_DIR_=.. for back 584338032Speter compatibility. 584438032Speter CONFIG: fix mail from <> so it will properly convert to 584538032Speter MAILER-DAEMON on local addresses. 584638032Speter CONFIG: fix code that was supposed to catch colons in host 584738032Speter names. Problem noted by John Gardiner Myers of CMU. 584838032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 584938032Speter From Paul Riddle of the University of Maryland, Baltimore 585038032Speter County. 585138032Speter CONFIG: Catch and reject "." as a host address. 585238032Speter CONFIG: Generalize domaintable to look up all domains, not 585338032Speter just unqualified ones. 585438032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 585538032Speter was never used and didn't work anyway. 585638032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 585738032Speter and d on all mailers in the UUCP class. 585838032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 585938032Speter look for an alias for "user+detail", then for "user+*", and 586038032Speter finally for "user". This is intended for forwarding mail 586138032Speter for system aliases such as root and postmaster to a 586238032Speter centralized hub. 586338032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 586438032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 586538032Speter The F=8 flag is also set on the "relay" mailer, since 586638032Speter this is expected to be another sendmail. 586738032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 586838032Speter the name of the UUCP_RELAY -- in some cases, this is the 586938032Speter wrong value (e.g., when we have local UUCP connections), 587038032Speter and this can create unreplyable addresses. From Chip 587138032Speter Rosenthal of Unicom. 587238032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 587364562Sgshapiro Received: header inserted into all messages. Suggested by 587438032Speter Gary Mills of the University of Manitoba. 587538032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 587643730Speter to get the old behavior. I did this upon observing 587738032Speter that almost everyone needed this feature, and that the 587838032Speter concept I was trying to make happen didn't work with 587938032Speter some user agents anyway. FEATURE(notsticky) still works, 588038032Speter but it is a no-op. 588138032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 588238032Speter names are sent, rather than immediately diagnosing them 588338032Speter as User Unknown. 588438032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 588538032Speter and RELAY_MAILER_ARGS to set the arguments for the 588638032Speter indicated mailers. All default to "IPC $h". Patch from 588738032Speter Larry Parmelee of Cornell University. 588838032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 588938032Speter on the client side" and F=P to get an appropriate 589038032Speter return-path. From Kimmo Suominen. 589138032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 589238032Speter as the local mailer. For addresses of the form "user+detail" 589338032Speter the "detail" part is passed to procmail via the -a flag. 589438032Speter Contributed by Kimmo Suominen. 589538032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 589638032Speter use from mailertables. This lets you execute arbitrary 589738032Speter procmail scripts. Contributed by Kimmo Suominen. 589838032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 589938032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 590038032Speter Paul Southworth of CICNet Systems Support. 590138032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 590238032Speter This causes the null return path to be rewritten as 590338032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 590438032Speter From Michael Hohmuth of Technische Universitat Dresden. 590538032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 590638032Speter list us as the best possible MX record to be treated as 590738032Speter though they were local (essentially, assume that they 590838032Speter are included in $=w). This can cause additional DNS 590938032Speter traffic, but is easier to administer if this fits your 591038032Speter local model. It does not work reliably if there are 591138032Speter multiple hosts that share the best MX preference. 591238032Speter Code contributed by John Oleynick of Rutgers. 591338032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 591438032Speter SHell) instead of /bin/sh as the program used for delivery 591538032Speter to programs. If an argument is included, it is used as 591638032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 591738032Speter assumed. 591838032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 591938032Speter size of messages to the local and procmail mailers 592038032Speter respectively. Contributed by Brad Knowles of the Defense 592138032Speter Information Systems Agency. 592238032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 592338032Speter (just like text outside of angle brackets) in order to 592438032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 592538032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 592638032Speter any real systems any more) and tweak the DOMAIN macro 592738032Speter so that it is less likely that users will accidentally use 592838032Speter the Berkeley defaults. Also, create some generic files 592938032Speter that really can be used in the real world. 593038032Speter CONFIG: Add new configuration macros to set character sets for 593138032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 593238032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 593338032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 593438032Speter The old name will still be accepted for a while at least. 593538032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 593638032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 593738032Speter As with all relays, it can be ``mailer:hostname''. Suggested 593838032Speter by Scott Hutton. 593938032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 594038032Speter by Barb Dijker of Labyrinth Computer Services. 594138032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 594238032Speter performance for large alias files, and this confused many 594338032Speter people. 594438032Speter CONFIG: Add confCF_VERSION to append local information to the 594538032Speter configuration version number displayed during SMTP startup. 594638032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 594738032Speter would only work when locally addressed. Fix from 594838032Speter Edvard Tuinder of Cistron Internet Services. 594938032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 595043730Speter "n" (CheckAliases) is set when rebuilding alias database. 595138032Speter Based on code contributed by Claude Marinier. 595238032Speter CONFIG: Allow mailertable to have values of the form 595338032Speter ``error:code message''. The ``code'' is a status code 595438032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 595538032Speter Contributed by David James <dwj@agw.bt.co.uk>. 595638032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 595738032Speter sender domains that will be replaced with the masquerade name. 595838032Speter These domains will not be treated as local, but if mail passes 595938032Speter through with sender addresses in those domains they will be 596038032Speter replaced by the masquerade name. These can also be specified 596138032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 596238032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 596338032Speter as well as the header. Substantial improvements to this 596438032Speter code were contributed by Per Hedeland. 596538032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 596638032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 596738032Speter by Kimmo Suominen. 596838032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 596938032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 597038032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 597138032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 597238032Speter UUCP addressing.

This caused UnixWare 611538032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 611638032Speter Novell Labs Europe. 611738032Speter Fix problem with static linking of local getopt routine when 611838032Speter using GNU's ld command. Fix from John Kennedy of 611938032Speter Cal State Chico. 612038032Speter It was possible to turn off privacy flags. Problem noted by 612138032Speter *Hobbit*. 612238032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 612338032Speter and Liudvikas Bukys. 612438032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 612538032Speter from Spider Boardman. 612638032Speter CONFIG: No changes (version number only, to keep it in sync 612738032Speter with the binaries). 612838032Speter 612964562Sgshapiro8.6.10/8.6.10 1995/02/10 613038032Speter SECURITY: Diagnose bogus values to some command line flags that 613138032Speter could allow trash to get into headers and qf files. 613238032Speter Validate the name of the user returned by the IDENT protocol. 613338032Speter Some systems that really dislike IDENT send intentionally 613438032Speter bogus information. Problem pointed out by Michael Bushnell 613538032Speter of the Free Software Foundation. Has some security 613638032Speter implications. 613738032Speter Fix a problem causing error messages about DNS problems when 613838032Speter the host name contained a percent sign to act oddly 613938032Speter because it was passed as a printf-style format string. 614038032Speter In some cases this could cause core dumps. 614138032Speter Avoid possible buffer overrun in returntosender() if error 614238032Speter message is quite long. From Fletcher Mattox of the 614338032Speter University of Texas. 614438032Speter Fix a problem that would silently drop "too many hops" error 614538032Speter messages if and only if you were sending to an alias. 614638032Speter From Jon Giltner of the University of Colorado and 614738032Speter Dan Harton of Oak Ridge National Laboratory. 614838032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 614938032Speter set and e->e_message was null. Fix from Bruce Nagel of 615038032Speter Data General. 615138032Speter Fix problem that can still cause df files to be left around 615238032Speter after "hop count exceeded" messages. Fix from Andrew 615338032Speter Chang and Shau-Ping Lo of SunSoft. 615438032Speter Fix a problem that can cause buffer overflows on very long 615538032Speter user names (as might occur if you piped to a program 615638032Speter with a lot of arguments). 615738032Speter Avoid returning an error and re-queueing if the host signature 615838032Speter is null; this can occur on addresses like ``user@.''. 615938032Speter Problem noted by Wesley Craig and the University of 616038032Speter Michigan. 616138032Speter Avoid possible calls to malloc(0) if MCI caching is turned 616238032Speter off. Bug fix from Pierre David of the Laboratoire 616338032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 616438032Speter Universite de Versailles - St Quentin, and Jacky 616538032Speter Thibault. 616638032Speter Make a local copy of the line being sent via senttolist() -- in 616738032Speter some cases, buffers could get trashed by map lookups 616838032Speter causing it to do unexpected things. This also simplifies 616938032Speter some of the map code. 617038032Speter CONFIG: No changes (version number only, to keep it in sync 617138032Speter with the binaries). 617238032Speter 617364562Sgshapiro8.6.9/8.6.9 1994/04/19 617438032Speter Do all mail delivery completely disconnected from any terminal. 617538032Speter This provides consistency with daemon delivery and 617638032Speter may have some security implications. 617738032Speter Make sure that malloc doesn't get called with zero size, 617838032Speter since that fails on some systems. Reported by Ed 617938032Speter Hill of the University of Iowa. 618038032Speter Fix multi-line values for $e (SMTP greeting message). Reported 618138032Speter by Mike O'Connor of Ford Motor Company. 618238032Speter Avoid syserr if no NIS domain name is defined, but the map it 618338032Speter is trying to open is optional. From Win Bent of USC. 618438032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 618538032Speter Hesiod support for UDB from Todd Miller of the University of 618638032Speter Colorado. Use "hesiod" as the service name in the U 618738032Speter option. 618838032Speter Fix a problem that failed to set the "authentic" host name (that 618938032Speter is, the one derived from the socket info) if you called 619038032Speter sendmail -bs from inetd. Based on code contributed by 619138032Speter Todd Miller (this problem was also reported by Guy Helmer 619238032Speter of Dakota State University). This also fixes a related 619338032Speter problem reported by Liudvikas Bukys of the University of 619438032Speter Rochester. 619538032Speter Parameterize "nroff -h" in all the Makefiles so people with 619638032Speter variant versions can use them easily. Suggested by 619738032Speter Peter Collinson of Hillside Systems. 619838032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 619938032Speter spaces between parameters instead of one. Reported by 620038032Speter Valdis Kletnieks of Virginia Tech. 620138032Speter Reduce the number of system calls during message collection by 620238032Speter using global timeouts around the collect() loop. This 620338032Speter code was contributed by Eric Wassenaar. 620438032Speter If the initial hostname name gathering results in a name 620538032Speter without a dot (usually caused by NIS misconfiguration) 620638032Speter and BIND is compiled in, directly access DNS to get 620738032Speter the canonical name. This should make life easier for 620838032Speter Solaris systems. If it still can't be resolved, and 620938032Speter if the name server is listed as "required", try again 621038032Speter in 30 seconds. If that also fails, exit immediately to 621138032Speter avoid bogus "config error: mail loops back to myself" 621238032Speter messages. 621338032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 621438032Speter message to explain how much space was available and 621538032Speter sound a bit less threatening. Suggested by Stan Janet 621638032Speter of the National Institute of Standards and Technology. 621738032Speter If mail is delivered to an alias that has an owner, deliver any 621838032Speter requested return-receipt immediately, and strip the 621938032Speter Return-Receipt-To: header from the subsequent message. 622038032Speter This prevents a certain class of denial of service 622138032Speter attack, arguably gives more reasonable semantics, and 622238032Speter moves things more towards what will probably become a 622338032Speter network standard. Suggested by Christopher Davis of 622438032Speter Kapor Enterprises. 622538032Speter Add a "noreceipts" privacy flag to turn off all return receipts 622638032Speter without recompiling. 622738032Speter Avoid printing ESMTP parameters as part of the error message 622838032Speter if there are errors during parsing. This change is 622938032Speter purely cosmetic. 623038032Speter Avoid sending out error messages during the collect phase of 623138032Speter SMTP; there is an MVS mailer from UCLA that gets 623238032Speter confused by this. Of course, I think it's their bug.... 623338032Speter Check for the $j macro getting undefined, losing a dot, or getting 623438032Speter lost from $=w in the daemon before accepting a connection; 623538032Speter if it is, it dumps state, prints a LOG_ALERT message, 623638032Speter and drops core for debugging. This is an attempt to 623738032Speter track down a bug that I thought was long since gone. 623838032Speter If you see this, please forward the log fragment to 623938032Speter sendmail@sendmail.ORG. 624038032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 624138032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 624238032Speter Wolfhugel. 624338032Speter Instead of trying to truncate the listen queue for the server 624438032Speter SMTP port when the load average is too high, just close 624538032Speter the port completely and reopen it later as needed. 624638032Speter This ensures that the other end gets a quick "connection 624738032Speter refused" response, and that the connection can be 624838032Speter recovered later. In particular, some socket emulations 624938032Speter seem to get confused if you tweak the listen queue 625038032Speter size around and can never start listening to connections 625138032Speter again. The down side is that someone could start up 625238032Speter another daemon process in the interim, so you could 625338032Speter have multiple daemons all not listening to connections; 625438032Speter this could in turn cause the sendmail.pid file to be 625538032Speter incorrect. A better approach might be to accept the 625638032Speter connection and give a 421 code, but that could break 625743730Speter other mailers in mysterious ways and have paging behavior 625838032Speter implications. 625938032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 626038032Speter set debugging on the wrong socket. From Eric Wassenaar. 626138032Speter When creating a df* temporary file, be sure you truncate any 626238032Speter existing data in the file -- otherwise system crashes 626338032Speter and the like could result in extra data being sent. 626438032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 626538032Speter doc directory. This includes some additional 626638032Speter information. 626738032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 626838032Speter of recipient envelope addresses. This should have been 626938032Speter handled by the $&h trick, but broke if people were 627038032Speter mixing domainized and UUCP addresses. They should 627138032Speter probably have converted all the way over to uucp-uudom 627238032Speter instead of uucp-{new,old}, but the failure mode was to 627338032Speter loop the mail, which was bad news. 627438032Speter Portability fixes: 627538032Speter Newer BSDI systems (several people). 627638032Speter Older BSDI systems from Christophe Wolfhugel. 627738032Speter Intergraph CLIX, from Paul Southworth of CICNet. 627838032Speter UnixWare, from Evan Champion. 627938032Speter NetBSD from Adam Glass. 628038032Speter Solaris from Quentin Campbell of the University of 628138032Speter Newcastle upon Tyne. 628238032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 628338032Speter Corporation. 628438032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 628538032Speter SunOS (it has setsid() and setvbuf() calls) from 628638032Speter Jonathan Kamens of OpenVision Technologies. 628738032Speter HP-UX from Tor Lillqvist. 628838032Speter New Files: 628938032Speter src/Makefile.CLIX 629038032Speter src/Makefile.NCR3000 629138032Speter doc/changes/Makefile 629238032Speter doc/changes/changes.me 629338032Speter doc/changes/changes.ps 629438032Speter 629564562Sgshapiro8.6.8/8.6.6 1994/03/21 629638032Speter SECURITY: it was possible to read any file as root using the 629738032Speter E (error message) option. Reported by Richard Jones; 629838032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 629938032Speter 630064562Sgshapiro8.6.7/8.6.6 1994/03/14 630138032Speter SECURITY: it was possible to get root access by using weird 630238032Speter values to the -d flag. Thanks to Alain Durand of 630338032Speter INRIA for forwarding me the notice from the bugtraq 630438032Speter list. 630538032Speter 630664562Sgshapiro8.6.6/8.6.6 1994/03/13 630738032Speter SECURITY: the ability to give files away on System V-based 630838032Speter systems proved dangerous -- don't run as the owner 630938032Speter of a :include: file on a system that allows giveaways. 631038032Speter Unfortunately, this also applies to determining a 631138032Speter valid shell. 631238032Speter IMPORTANT: Previous versions weren't expiring old connections 631338032Speter in the connection cache for a long time under some 631438032Speter circumstances. This could result in resource exhaustion, 631538032Speter both at your end and at the other end. This checks the 631638032Speter connections for timeouts much more frequently. From 631738032Speter Doug Anderson of NCSC. 631838032Speter Fix a glitch that snuck in that caused programs to be run as 631938032Speter the sender instead of the recipient if the mail was 632038032Speter from a local user to another local user. From 632138032Speter Motonori Nakamura of Kyoto University. 632238032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 632338032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 632438032Speter Bryan Costales of ICSI. 632538032Speter Change the method used to declare the "statfs" availability; 632638032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 632738032Speter tweaking in conf.c, there is a single #define called 632838032Speter SFS_TYPE which takes on one of six values (SFS_NONE 632938032Speter for no statfs availability, SFS_USTAT for the ustat(2) 633038032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 633138032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 633238032Speter statfs(2) call with the declarations in <sys/vfs.h>, 633338032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 633438032Speter Fix glitch in NetInfo support that could return garbage if 633538032Speter there was no "/locations/sendmail" property. From 633638032Speter David Meyer of the University of Virginia. 633738032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 633838032Speter to allow Linux to turn it off even though it is a 633938032Speter BSD-like system. 634038032Speter Allow setting of "ident" timeout to zero to turn off the ident 634138032Speter protocol entirely. 634238032Speter Make 7-bit stripping local to a connection (instead of to a 634338032Speter mailer); this allows you to specify that SMTP is a 634438032Speter 7-bit channel, but revert to 8-bit should it advertise 634538032Speter that it supports 8BITMIME. You still have to specify 634638032Speter mailer flag 7 to get this stripping at all. 634738032Speter Improve makesendmail script so it handles more cases automatically. 634838032Speter Tighten up restrictions on taking ownership of :include: files 634938032Speter to avoid problems on systems that allow you to give away 635038032Speter files. 635138032Speter Fix a problem that made it impossible to rebuild the alias 635238032Speter file if it was on a read-only file system. From 635338032Speter Harry Edmon of the University of Washington. 635438032Speter Improve MX randomization function. From John Gardiner Myers 635538032Speter of CMU. 635638032Speter Fix a minor glitch causing a bogus message to be printed (used 635738032Speter %s instead of %d in a printf string for the line number) 635838032Speter when a bad queue file was read. From Harry Edmon. 635938032Speter Allow $s to remain NULL on locally generated mail. I'm not 636038032Speter sure this is necessary, but a lot of people have complained 636138032Speter about it, and there is a legitimate question as to whether 636238032Speter "localhost" is legal as an 822-style domain. 636338032Speter Fix a problem with very short line lengths (mailer L= flag) in 636438032Speter headers. This causes a leading space to be added onto 636538032Speter continuation lines (including in the body!), and also 636638032Speter tries to wrap headers containing addresses (From:, To:, 636738032Speter etc) intelligently at the shorter line lengths. Problem 636838032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 636938032Speter Log the real user name when logging syserrs, since these can have 637038032Speter security implications. Suggested by several people. 637138032Speter Fix address logging of cached connections -- it used to always 637238032Speter log the numeric address as zero. This is a somewhat 637338032Speter bogus implementation in that it does an extra system 637438032Speter call, but it should be an inexpensive one. Fix from 637538032Speter Motonori Nakamura. 637638032Speter Tighten up handling of short syslog buffers even more -- there 637738032Speter were cases where the outgoing relay= name was too long 637838032Speter to share a line with delay= and mailer= logging. 637938032Speter Limit the overhead on split envelopes to one open file descriptor 638038032Speter per envelope -- previously the overhead was three 638138032Speter descriptors. This was in response to a problem reported 638238032Speter by P{r (Pell) Emanuelsson. 638338032Speter Fixes to better handle the case of unexpected connection closes; 638438032Speter this redirects the output to the transcript so the info 638538032Speter is not lost. From Eric Wassenaar. 638638032Speter Fix potential string overrun if you macro evaluate a string that 638738032Speter has a naked $ at the end. Problem noted by James Matheson 638838032Speter <jmrm@eng.cam.ac.uk>. 638938032Speter Make default error number on $#error messages 553 (``Requested 639038032Speter action not taken: mailbox name not allowed'') instead of 639138032Speter 501 (``Syntax error in parameters or arguments'') to 639238032Speter avoid bogus "protocol error" messages. 639338032Speter Strip off any existing trailing dot on names during $[ ... $] 639438032Speter lookup. This prevents it from ending up with two dots 639538032Speter on the end of dot terminated names. From Wesley Craig 639638032Speter of the University of Michigan and Bryan Costales of ICSI. 639738032Speter Clean up file class reading so that the debugging information is 639838032Speter more informative. It hadn't been using setclass, so you 639938032Speter didn't see the class items being added. 640038032Speter Avoid core dump if you are running a version of sendmail where 640138032Speter NIS is compiled in, and you specify an NIS map, but 640238032Speter NIS is not running. Fix from John Oleynick of 640338032Speter Rutgers. 640438032Speter Diagnose bizarre case where res_search returns a failure value, 640538032Speter but sets h_errno to a success value. 640638032Speter Make sure that "too many hops" messages are considered important 640738032Speter enough to send an error to the Postmaster (that is, the 640838032Speter address specified in the P option). This fix should 640938032Speter help problems that cause the df file to be left around 641038032Speter sometimes -- unfortunately, I can't seem to reproduce 641138032Speter the problem myself. 641238032Speter Avoid core dump (null pointer reference) on EXPN command; this 641338032Speter only occurred if your log level was set to 10 or higher 641438032Speter and the target account was an alias or had a .forward file. 641538032Speter Problem noted by Janne Himanka. 641638032Speter Avoid "denial of service" attacks by someone who is flooding your 641738032Speter SMTP port with bad commands by shutting the connection 641838032Speter after 25 bad commands are issued. From Kyle Jones of 641938032Speter UUNET. 642038032Speter Fix core dump on error messages with very long "to" buffers; 642138032Speter fmtmsg overflows the message buffer. Fixed by trimming 642238032Speter the to address to 203 characters. Problem reported by 642338032Speter John Oleynick. 642438032Speter Fix configuration for HASFLOCK -- there were some spots where 642538032Speter a #ifndef was incorrectly #ifdef. Pointed out by 642638032Speter George Baltz of the University of Maryland. 642738032Speter Fix a typo in savemail() that could cause the error message To: 642838032Speter lists to be incorrect in some places. From Motonori 642938032Speter Nakamura. 643038032Speter Fix a glitch that can cause duplicate error messages on split 643138032Speter envelopes where an address on one of the lists has a 643238032Speter name server failure. Fix from Voradesh Yenbut of the 643338032Speter University of Washington. 643438032Speter Fix possible bogus pointer reference on ESMTP parameters that 643538032Speter don't have an ``=value'' part. 643638032Speter CNAME loops caused an error message to be generated, but also 643738032Speter re-queued the message. Changed to just re-queue the 643838032Speter message (it's really hard to just bounce it because 643938032Speter of the weird way the name server works in the presence 644038032Speter of CNAME loops). Problem noted by James M.R.Matheson 644138032Speter of Cambridge University. 644238032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 644338032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 644438032Speter user name. Suggested by Andreas Stolcke of ICSI. 644538032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 644638032Speter override it easily in the Makefile -- that is, you can 644738032Speter turn it off using -DNAMED_BIND=0. 644838032Speter If a gethostbyname(...) of an address with a trailing dot fails, 644938032Speter try it without the trailing dot. This is because if 645038032Speter you have a version of gethostbyname() that falls back 645138032Speter to NIS or the /etc/hosts file it will fail to find 645238032Speter perfectly reasonable names that just don't happen to 645338032Speter be dot terminated in the hosts file. You don't want to 645438032Speter strip the dot first though because we're trying to ensure 645538032Speter that country names that match one of your subdomains get 645638032Speter a chance. 645738032Speter PRALIASES: fix bogus output on non-null-terminated strings. 645838032Speter From Bill Gianopoulos of Raytheon. 645938032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 646038032Speter This was in code intended to only catch the self-literal 646138032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 646238032Speter IP address), but the code was broken. However, it will 646338032Speter still do this if $M is defined; this is necessary to 646438032Speter get client configurations to work (sigh). Note that this 646538032Speter means that $M overrides :mailname entries in the user 646638032Speter database! Problem noted by Paul Southworth. 646738032Speter CONFIG: Fix definition of Solaris help file location. From 646838032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 646938032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 647038032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 647138032Speter and USENET_MAILER_MAX to tweak the maximum message 647238032Speter size for various mailers. 647338032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 647438032Speter instead of assuming that it is "inews" for consistency 647538032Speter with other mailers. From Michael Corrigan of UC San Diego. 647638032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 647738032Speter qualify the address in the SMTP envelope as user@{relay|hub} 647838032Speter instead of user@$j. From Bill Wisner of The Well. 647938032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 648038032Speter CONFIG: Don't turn off case mapping of user names in the local 648138032Speter mailer for IRIX. This was different than most every other 648238032Speter system. 648338032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 648438032Speter envelope. Noted by Thierry Besancon 648538032Speter <besancon@excalibur.ens.fr>. 648638032Speter CONFIG: Don't include -z by default on uux line -- most systems 648738032Speter don't want it set by default. Pointed out by Philippe 648838032Speter Michel of Thomson CSF. 648938032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 649038032Speter host name was foo.bar.ray.com and you matched against 649138032Speter ".ray.com", the old implementation bound %1 to "bar" 649238032Speter instead of "foo.bar". Also, allow "." in the mailertable 649338032Speter to match anything -- essentially, take over SMART_HOST. 649438032Speter This also moves matching of explicit local host names 649538032Speter before the mailertable so they don't have to be special 649638032Speter cased in the mailertable data. Reported by Bill 649738032Speter Gianopoulos of Raytheon; the fix for the %1 binding 649838032Speter problem was contributed by Nicholas Comanos of the 649938032Speter University of Sydney. 650038032Speter CONFIG: Don't include "root" in class $=L (users to deliver 650138032Speter locally, even if a hub or relay exists) by default. 650238032Speter This is because of the known bug where definition of 650338032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 650438032Speter both and deliver into the local mailbox. 650538032Speter CONFIG: Move up bitdomain and uudomain handling so that they 650638032Speter are done before .UUCP class matching; uudomain was 650738032Speter reported as ineffective before. This also frees up 650838032Speter diversion 8 for future use. Problem reported by Kimmo 650938032Speter Suominen. 651038032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 651138032Speter into host names. As pointed out by Jonathan Kamens, 651238032Speter these are often used because either the forward or reverse 651338032Speter mapping is broken; this translation makes it broken again. 651438032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 651538032Speter Suominen. 651638032Speter Portability fixes: 651738032Speter Unicos from David L.

From 654138032Speter Bob Campbell at U.C. Berkeley. 654238032Speter Security fix: group ids were not completely set when programs 654338032Speter were invoked. This caused programs to have group 654438032Speter permissions they should not have had (usually group 654538032Speter daemon instead of their own group). In particular, 654638032Speter Perl scripts would refuse to run. 654738032Speter Security: check to make sure files that are written are not 654838032Speter symbolic links (at least under some circumstances). 654938032Speter Although this does not respond to a specific known 655038032Speter attack, it's just a good idea. Suggested by 655138032Speter Christian Wettergren. 655238032Speter Security fix: if a user had an NFS mounted home directory on 655338032Speter a system with a restricted shell listed in their 655438032Speter /etc/passwd entry, they could still execute any 655538032Speter program by putting that in their .forward file. 655638032Speter This fix prevents that by insisting that their shell 655738032Speter appear in /etc/shells before allowing a .forward to 655838032Speter execute a program or write a file. You can disable 655938032Speter this by putting "*" in /etc/shells. It also won't 656038032Speter permit world-writable :include: files to reference 656138032Speter programs or files (there's no way to disable this). 656243730Speter These behaviors are only one level deep -- for 656338032Speter example, it is legal for a world-writable :include: 656438032Speter file to reference an alias that writes a file, on 656538032Speter the assumption that the alias file is well controlled. 656638032Speter Security fix: root was not treated suspiciously enough when 656738032Speter looking into subdirectories. This would potentially 656838032Speter allow a cracker to examine files that were publicly 656938032Speter readable but in a non-publicly searchable directory. 657038032Speter Fix a problem that causes an error on QUIT on a cached 657138032Speter connection to create problems on the current job. 657238032Speter These are typically unrelated, so errors occur in 657338032Speter the wrong place. 657438032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 657538032Speter runs more responsive to load average, and fixes a 657638032Speter problem that ignored the load average in locally 657738032Speter generated mail. From Eric Wassenaar. 657838032Speter Fix possible core dump on aliases with null LHS. From 657938032Speter John Orthoefer of BB&N. 658038032Speter Revert to using flock() whenever possible -- there are just 658138032Speter too many bugs in fcntl() locking, particularly over 658238032Speter NFS, that cause sendmail to fail in perverse ways. 658338032Speter Fix a bug that causes the connection cache to get confused 658438032Speter when sending error messages. This resulted in 658538032Speter "unexpected close" messages. It should fix itself 658638032Speter on the following queue run. Problem noted by 658738032Speter Liudvikas Bukys of the University of Rochester. 658838032Speter Include $k in $=k as documented in the Install & Op Guide. 658938032Speter This seems odd, but it was documented.... From 659038032Speter Michael Corrigan of UCSD. 659138032Speter Fix problem that caused :include:s from alias files to be 659238032Speter forced to be owned by root instead of daemon 659338032Speter (actually DefUid). From Tim Irvin. 659438032Speter Diagnose unrecognized I option values -- from Mortin Forssen 659538032Speter of the Chalmers University of Technology. 659638032Speter Make "error" mailer work consistently when there is no error 659738032Speter code associated with it -- previously it returned OK 659838032Speter even though there was a real problem. Now it assumes 659938032Speter EX_UNAVAILABLE. 660038032Speter Fix bug that caused the last header line of messages that had 660138032Speter no body and which were terminated with EOF instead of 660238032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 660338032Speter Fix core dump on SMTP mail to programs that failed -- it tried 660438032Speter to go to a "next MX host" when none existed, causing 660538032Speter a core dump. From der Mouse at McGill University. 660638032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 660738032Speter this makes it easier to turn it off (using 660838032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 660938032Speter Fix YP_MASTER_NAME store to use the unupdated result of 661038032Speter gethostname() (instead of myhostname(), which tries 661138032Speter to fully qualify the name) to be consistent with 661238032Speter SunOS. If your hostname is unqualified, this fixes 661338032Speter transfers to slave servers. Bug noted by Keith 661438032Speter McMillan of Ameritech Services, Inc. 661538032Speter Fix Ultrix problem: gethostbyname() can return a very large 661638032Speter (> 500) h_length field, which causes the sockaddr 661738032Speter to be trashed. Use the size of the sockaddr instead. 661838032Speter Fix from Bob Manson of Ohio State. 661938032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 662038032Speter defined -- this confuses gethostbyname on hosts 662138032Speter file lookups, which doesn't understand the trailing 662238032Speter dot convention. 662338032Speter Log SMTP server subprocesses that die with a signal instead 662438032Speter of from a clean exit. 662538032Speter If you don't have option "I" set, don't assume that a DNS 662638032Speter "host unknown" message is authoritative -- it 662738032Speter might still be found in /etc/hosts. 662838032Speter Fix a problem that would cause Deferred: messages to be sent 662938032Speter as the subject of an error message, even though the 663038032Speter actual cause of a message was more severe than that. 663138032Speter Problem noted by Chris Seabrook of OSSI. 663238032Speter Fix race condition in DBM alias file locking. From Kyle 663338032Speter Jones of UUNET. 663438032Speter Limit delivery syslog line length to avoid bugs in some 663538032Speter versions of syslog(3). This adds a new compile time 663638032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 663738032Speter University, which is in turn derived from IDA. 663838032Speter Fix quotes inside of comments in addresses -- previously 663938032Speter it insisted that they be balanced, but the 822 spec 664038032Speter says that they should be ignored. 664138032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 664238032Speter debugging). This also evaluates ruleset 89, if set 664338032Speter (with the null input), and logs the result. This 664438032Speter should be used sparingly, since the rewrite process 664538032Speter is not reentrant. 664638032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 664738032Speter documented in the Bat Book. 664838032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 664938032Speter return an error message and did not requeue the message. 665038032Speter Fix based on code from Roland Dirlewanger of 665138032Speter Reseau Regional Aquarel, Bordeaux, France. 665238032Speter Fix a problem that caused a seg fault if you got a 421 error 665338032Speter code during some parts of connection initialization. 665438032Speter I've only seen this when talking to buggy mailers on 665538032Speter the other end, but it shouldn't give a seg fault in 665638032Speter any case. From Amir Plivatsky. 665738032Speter Fix core dump caused by a ruleset call that returns null. 665838032Speter Fix from Bryan Costales of ICSI. 665938032Speter Full-Name: field was being ignored.

Suggested by 666638032Speter Bryan Costales. 666738032Speter Initialize non-alias maps during alias rebuilds -- they may be 666838032Speter needed for parsing. Problem noted by Douglas Anderson. 666938032Speter Log sender address even if no message was collected in SMTP 667038032Speter (e.g., if all RCPTs failed). Suggested by Motonori 667138032Speter Nakamura. 667238032Speter Don't reflect the owner-list contents into the envelope sender 667338032Speter address if the value contains ", :, /, or | (to avoid 667438032Speter illegal addresses appearing there). 667538032Speter Efficiency hack for toktype macro -- from Craig Partridge of 667638032Speter BB&N. 667738032Speter Clean up DNS error printing so that a host name is always 667838032Speter included. 667938032Speter Remember to set $i during queue runs. Reported by Stephen 668038032Speter Campbell of Dartmouth University. 668138032Speter If the environment variable HOSTALIASES is set, use it during 668238032Speter canonification as the name of a file with per-user host 668338032Speter translations so that headers are properly mapped.

From Vince 669338032Speter DeMarco. 669438032Speter Fix a glitch that sometimes caused :include:s that pointed to 669538032Speter NFS filesystems that were down to give an "aliasing/ 669638032Speter forwarding loop broken" message instead of queueing 669738032Speter the message for retry. Noted by William C Fenner of 669838032Speter the NRL Connection Machine Facility. 669938032Speter Fix a problem that could cause a core dump if the input sequence 670038032Speter had (or somehow acquired) a \231 character. 670138032Speter Make sure that route-addrs always have <angle brackets> around 670238032Speter them in non-SMTP envelopes (SMTP envelopes already do 670338032Speter this properly). 670438032Speter Avoid weird headers on unbalanced punctuation of the form: 670538032Speter ``Joe User <user)'' -- this caused reference to the 670638032Speter null macro. Fix from Rick McCarty of IO.COM. 670738032Speter Fix a problem that caused an alias "user: user@local.host" to 670838032Speter not have the QNOTREMOTE bit set; this caused configs 670938032Speter to act as if FEATURE(notsticky) was defined even when 671038032Speter it was not. The effect of the problem was to make it 671138032Speter very hard to to set up satellite sites that had a few 671238032Speter local accounts, with everything else forwarded to a 671338032Speter corporate hub. Reported by Detlef Drewanz of the 671438032Speter University of Rostock and Mark Frost of NCD. 671538032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 671638032Speter addresses. This is more efficient (fewer name server 671738032Speter calls) and fixes certain unusual configurations, such 671838032Speter as those that have ruleset 4 do something that is 671938032Speter non-idempotent unless a mailer-specific ruleset did 672038032Speter something else. Problem reported by Brian J.

Briefly, if you are sending to host 678938032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 679038032Speter "foo!baz" remains "foo!baz", and anything else has 679138032Speter the local name prepended. 679238032Speter CONFIG: portability fixes for HP-UX. 679338032Speter DOC: several minor problems fixed in the Install & Op Guide. 679438032Speter MAKEMAP: fix core dump problem on lines that are too long or 679538032Speter which lack newline. From Mark Delany. 679638032Speter MAILSTATS: print sums of columns (total messages & kbytes 679738032Speter in and out of the system). From Tom Ferrin of UC 679838032Speter San Francisco Computer Graphics Lab. 679938032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 680038032Speter On HP-UX, /etc/sendmail.cf has been moved to 680138032Speter /usr/lib/sendmail.cf to match HP sendmail. 680238032Speter Permissions have been tightened up on world-writable 680338032Speter :include: files and accounts that have shells 680438032Speter that are not listed in /etc/shells. This may 680538032Speter cause some .forward files that have worked 680638032Speter before to start failing. 680738032Speter SIGUSR1 dumps some state to the log. 680838032Speter NEW FILES: 680938032Speter src/Makefile.DGUX 681038032Speter src/Makefile.Dynix 681138032Speter src/Makefile.FreeBSD 681238032Speter src/Makefile.Mach386 681338032Speter src/Makefile.NetBSD 681438032Speter src/Makefile.RISCos 681538032Speter src/Makefile.SCO 681638032Speter src/Makefile.SVR4 681738032Speter src/Makefile.Titan 681838032Speter cf/mailer/pop.m4 681938032Speter cf/ostype/bsdi1.0.m4 682038032Speter cf/ostype/dgux.m4 682138032Speter cf/ostype/dynix3.2.m4 682238032Speter cf/ostype/sco3.2.m4 682338032Speter makemap/Makefile.dist 682438032Speter praliases/Makefile.dist 682538032Speter 682664562Sgshapiro8.6.4/8.6.4 1993/10/31 682738032Speter Repair core-dump problem (write to read-only memory segment) 682838032Speter if you fall back to the return-to-Postmaster case in 682938032Speter savemail. Problem reported by Richard Liu. 683038032Speter Immediately diagnose bogus sender addresses in SMTP. This 683138032Speter makes quite certain that crackers can't use this 683238032Speter class of attack. 683338032Speter Reliability Fix: check return value from fclose() and fsync() 683438032Speter in a few critical places. 683538032Speter Minor problem in initsys() that reversed a condition for 683638032Speter redirecting the output channel on queue runs. It's 683738032Speter not clear this code even does anything. From Eric 683838032Speter Wassenaar of the Dutch National Institute for Nuclear 683938032Speter and High-Energy Physics. 684038032Speter Fix some problems that caused queue runs to do "too much work", 684138032Speter such as double-reading the Errors-To: header. From 684238032Speter Eric Wassenaar. 684338032Speter Error messages on writing the temporary file (including the 684438032Speter data file) were getting suppressed in SMTP -- this 684538032Speter fix causes them to be properly reported. From Eric 684638032Speter Wassenaar. 684738032Speter Some changes to support AF_UNIX sockets -- this will only 684838032Speter really become relevant in the next release, but some 684938032Speter people need it for local patches. From Michael 685038032Speter Corrigan of UC San Diego. 685138032Speter Use dynamically allocated memory (instead of static buffers) 685238032Speter for macros defined in initsys() and settime(); since 685338032Speter these can have different values depending on which 685438032Speter envelope they are in. From Eric Wassenaar. 685538032Speter Improve logging to show ctladdr on to= logging; this tells you 685638032Speter what uid/gid processes ran as. 685738032Speter Fix a problem that caused error messages to be discarded if 685838032Speter the sender address was unparseable for some reason; 685938032Speter this was supposed to fall back to the "return to 686038032Speter postmaster" case. 686138032Speter Improve aliaswait backoff algorithm. 686238032Speter Portability patches for Linux (8.6.3 required another header 686338032Speter file) (from Karl London) and SCO UNIX. 686438032Speter CONFIG: patch prog mailer to not strip host name off of envelope 686538032Speter addresses (so that it matches local again). From 686638032Speter Christopher Davis. 686738032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 686838032Speter this prevents uux from seeing lines with null names like 686938032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 687038032Speter Nakamura of Kyoto University. 687138032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 687238032Speter it shouldn't fail miserably. From Motonori Nakamura. 687338032Speter 687464562Sgshapiro8.6.2/8.6.2 1993/10/15 687538032Speter Put a "successful delivery" message in the transcript for 687638032Speter addresses that get return-receipts. 687738032Speter Put a prominent "this is only a warning" message in warning 687838032Speter messages -- some people don't read carefully enough 687938032Speter and end up sending the message several times. 688038032Speter Include reason for temporary failure in the "warning" return 688138032Speter message. Currently, it just says "cannot send for 688238032Speter four hours". 688338032Speter Fix the "Original message received" time generated for 688438032Speter returntosender messages. It was previously listed as 688538032Speter the current time. Bug reported by Eric Hagberg of 688638032Speter Cornell University Medical College. 688738032Speter If there is an error when writing the body of a message, 688838032Speter don't send the trailing dot and wait for a response 688938032Speter in sender SMTP, as this could cause the connection to 689038032Speter hang up under some bizarre circumstances. From Eric 689138032Speter Wassenaar. 689238032Speter Fix some server SMTP synchronization problems caused when 689338032Speter connections fail during message collection. From 689438032Speter Eric Wassenaar. 689538032Speter Fix a problem that can cause srvrsmtp to reject mail if the 689638032Speter name server is down -- it accepts the RCPT but rejects 689738032Speter the DATA command. Problem reported by Jim Murray of 689838032Speter Stratus. 689938032Speter Fix a problem that can cause core dumps if the config file 690038032Speter incorrectly resolves to a null hostname. Reported by 690138032Speter Allan Johannesen of WPI. 690238032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 690338032Speter by non-root users were not put into 690438032Speter X-Authentication-Warning:s as intended because the 690543730Speter config file hadn't set the PrivacyOptions yet. Fix 690638032Speter from Sven-Ove Westberg of the University of Lulea. 690738032Speter Under very odd circumstances, the alias file rebuild code 690838032Speter could get confused as to whether a database was 690938032Speter open or not. 691038032Speter Check "vendor code" on the end of V lines -- this is 691138032Speter intended to provide a hook for vendor-specific 691238032Speter configuration syntax. (This is a "new feature", 691338032Speter but I've made an exception to my rule in a belief 691438032Speter that this is a highly exceptional case.) 691538032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 691638032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 691738032Speter (from Jon Forrest of UC Berkeley) 691838032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 691938032Speter 692064562Sgshapiro8.6.1/8.6 1993/10/08 692138032Speter Portability fixes for A/UX and Encore UMAX V. 692238032Speter Fix error message handling -- if you had a name server down 692338032Speter causing an error during parsing, that message was never 692438032Speter propagated to the queue file. 692538032Speter 692664562Sgshapiro8.6/8.6 1993/10/05 692738032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 692838032Speter conf.h (other systems have the same bug). 692938032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 693038032Speter getdtablesize() instead of sysconf(); a disturbingly 693138032Speter large number of systems defined _SC_OPEN_MAX in the 693238032Speter header files but don't have the syscall. 693338032Speter Another patch to really truly ignore MX records in getcanonname 693438032Speter if trymx == FALSE. 693538032Speter Fix problem that caused the "250 IAA25499 Message accepted for 693638032Speter delivery" message to be omitted if there was an error 693738032Speter in the header of the message (e.g., a bad Errors-To: 693838032Speter line). Pointed out by Michael Corrigan of UCSD. 693938032Speter Announce name of host we are chatting when we get errors; this 694038032Speter is an IDA-ism suggested by Christophe Wolfhugel. 694138032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 694238032Speter Australian Artificial Intelligence Institute), SCO Unix 694338032Speter (from Murray Kucherawy of Hookup Communication Corp.), 694438032Speter NeXT (from Vince DeMarco and myself), Linux (from 694538032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 694638032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 694738032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 694838032Speter Some changes to get around gcc optimizer bugs. From Takahiro 694938032Speter Kanbe. 695038032Speter Fix error recovery in queueup if another tf file of the same 695138032Speter name already exists. Problem stumbled over by Bill 695238032Speter Wisner of The Well. 695338032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 695438032Speter Problem noted by Keith McMillan of Ameritech Services. 695538032Speter Deal with group permissions properly when opening .forward and 695638032Speter :include: files. This relaxes the 8.1C restrictions 695738032Speter slightly more. This includes proper setting of groups 695838032Speter when reading :include: files, allowing you to read some 695938032Speter files that you should be able to read but have previously 696038032Speter been denied unless you owned them or they had "other" 696138032Speter read permission. 696238032Speter Make certain that $j is in $=w (after the .cf is read) so that 696338032Speter if the user is forced to override some silly system, 696438032Speter MX suppression will still work. 696538032Speter Fix a couple of efficiency problems where newstr was double- 696638032Speter calling expensive routines. In at least one case, it 696738032Speter wasn't guaranteed that they would always return the 696838032Speter same result. Problem noted by Christophe Wolfhugel. 696938032Speter Fix null pointer dereference in putoutmsg -- only on an error 697038032Speter condition from a non-SMTP mailer. From Motonori 697138032Speter Nakamura. 697238032Speter Macro expand "C" line class definitions before scanning so that 697338032Speter "CX $Z" works. 697438032Speter Fix problem that caused error message to be sent while still 697538032Speter trying to send the original message if the connection 697638032Speter is closed during a DATA command after getting an error 697738032Speter on an RCPT command (pretty obscure). Problem reported 697838032Speter by John Myers of CMU. 697938032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 698038032Speter term bug. 698138032Speter Fix a nasty bug causing core dumps when returning the "warning: 698238032Speter cannot deliver for N hours -- will keep trying" message; 698343730Speter it only occurred if you had PostmasterCopy set and 698438032Speter only on some architectures. Although sendmail would 698538032Speter keep trying, it would send error messages on each 698638032Speter queue interval. This is an important fix. 698738032Speter Allow u and g options to take user and group names respectively. 698838032Speter Don't do a chdir into the queue directory in -bt mode to make 698938032Speter ruleset testing a bit easier. 699038032Speter Don't allow users to turn off logging (using -oL) on the command 699138032Speter line -- command line can only raise, not lower, logging 699238032Speter level. 699338032Speter Set $u to the original recipient on the SMTP transaction or on 699438032Speter the command line. This is only done if there is exactly 699538032Speter one recipient. Technically, this does not meet the 699638032Speter specs, because it does not guarantee a domain on the 699738032Speter address. 699838032Speter Fix a problem that dumped error messages on bad addresses if 699938032Speter you used the -t flag. Problem noted by Josh Smith of 700038032Speter Harvey Mudd College. 700138032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 700238032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 700338032Speter avoid the problem of people who use angle brackets in 700438032Speter their full name information. 700538032Speter Fix a null pointer dereference if you set option "l", have 700638032Speter an Errors-To: header in the message, and have Errors-To: 700738032Speter defined in the config file H lines. From J.R. Oldroyd. 700838032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 700938032Speter wrong when compiling. Suggested by Rick McCarty of TI. 701038032Speter Fix a problem that could pass negative SIZE parameter if the 701138032Speter df file got lost; this would cause servers to always 701238032Speter give a temporary failure, making the problem even worse. 701338032Speter Problem noted by Allan Johannesen of WPI. 701438032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 701538032Speter protocol timeouts (30s default). Requested by Murray 701638032Speter Kucherawy of HookUp Communication Corp. to handle bogus 701738032Speter PC TCP/IP implementations. 701838032Speter Change $w default definition to be just the first component of 701938032Speter the domain name on config level 5. The $j macro defaults 702038032Speter to the FQDN; $m remains as before. This lets well-behaved 702138032Speter config files use any of the short, long, or subdomain 702238032Speter names. 702338032Speter Add makesendmail script in src to try to automate multi-architecture 702438032Speter builds. I know, this is sub-optimal, but it is still 702538032Speter helpful. 702638032Speter Fix very obscure race condition that can cause a queue run to 702738032Speter get a queue file for an already completed job. This 702838032Speter problem has existed for years. Problem noted by the 702938032Speter long suffering Allan Johannesen of WPI. 703038032Speter Fix a problem that caused the raw sender name to be passed to 703138032Speter udbsender instead of the canonified name -- this caused 703238032Speter it to sometimes miss records that it should have found. 703338032Speter Relax check of name on HELO packet so that a program using -bs 703438032Speter that claims to be itself works properly. 703538032Speter Restore rewriting of $: part of address through 2, R, 4 in 703638032Speter buildaddr -- this requires passing a lot of flags to get 703738032Speter it right. Unlike old versions, this ONLY rewrites 703838032Speter recipient addresses, not sender addresses. 703938032Speter Fix a bug that caused core dumps in config files that cannot 704038032Speter resolve /file/name style addresses. Fix from Jonathan 704138032Speter Kamens of OpenVision Technologies. 704238032Speter Fix problem with fcntl locking that can cause error returns to 704338032Speter be lost if the lock is lost; this required fully 704438032Speter queueing everything, dropping the envelope (so errors 704538032Speter would get returned), and then re-reading the queue from 704638032Speter scratch. 704738032Speter Fix a problem that caused aliases that redefine an otherwise 704838032Speter true address to still send to the original address 704938032Speter if and only if the alias failed in certain bizarre 705038032Speter ways (e.g, if they pointed at a list:; syntax address). 705138032Speter Problem pointed out by Jonathan Kamens. 705238032Speter Remove support for frozen configuration files. They caused 705338032Speter more trouble than it was worth. 705438032Speter Fix problem that can cause error messages to get ignored when 705538032Speter using both -odb and -t flags. Problem noted by Rob 705638032Speter McNicholas at U.C. Berkeley. 705738032Speter Include all "normal" variations on hostname in $=w. For example, 705838032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 705938032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 706038032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 706138032Speter the queue. 706238032Speter Reset SmtpPhase global on initial connection creation so that 706338032Speter messages don't come out with stale information. 706438032Speter Pass an "ext" argument to lockfile so that error/log messages 706538032Speter will properly reflect the true filename being locked. 706638032Speter Put all [...] address forms into $=w -- this eliminates the need 706738032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 706838032Speter Myers of CMU. 706938032Speter Fix a bug that can cause qf files to be left around even after 707038032Speter an SMTP RSET command. Problem and fix from Michael 707138032Speter Corrigan. 707243730Speter Don't send a PostmasterCopy to errors when the Precedence: is 707338032Speter negative. Error reports still go to the envelope 707438032Speter sender address. 707538032Speter Add LA_SHORT for load averages. 707638032Speter Lock sendmail.st file when posting statistics. 707738032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 707838032Speter set the size of the TCP send and receive buffers; if you 707938032Speter run over a slow slip line you may need to set these down 708038032Speter (although it would be better to fix the SLIP implementation 708138032Speter so that it's not necessary to recompile every program 708238032Speter that does bulk data transfer). 708338032Speter Allow null defaults on $( ... $) lookups. Problem reported by 708438032Speter Amir Plivatsky. 708538032Speter Diagnose crufty S and V config lines. This resulted from an 708638032Speter observation that some people were using the SITE macro 708738032Speter without the SITECONFIG macro first, which was causing 708838032Speter bogus config files that were not caught. 708938032Speter Fix makemap -f flag to turn off case folding (it was turning it 709038032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 709138032Speter Fix a problem that caused multiple error messages to be sent if 709238032Speter you used "sendmail -t -oem -odb", your system uses fcntl 709338032Speter locking, and one of the recipient addresses is unknown. 709438032Speter Reset uid earlier in include() so that recursive .forwards or 709538032Speter :include:s don't use the wrong uid. 709638032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 709738032Speter called, the code to recover the descriptor was broken. 709838032Speter This sometimes (only sometimes) caused problems with the 709938032Speter alias file. Fix from Motonori Nakamura. 710038032Speter Fix a problem that caused aliaswait to go into infinite recursion 710138032Speter if the @:@ metasymbol wasn't found in the alias file. 710238032Speter Improve error message on newaliases if database files cannot be 710338032Speter opened or if running with no database format defined. 710438032Speter Do a better estimation of the size of error messages when NoReturn 710538032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 710638032Speter Fix a problem causing the "c" option (don't connect to expensive 710738032Speter mailers) to be ignored in SMTP. Problem noted and the 710838032Speter solution suggested by Robert Elz of The University of 710938032Speter Melbourne. 711038032Speter Improve connection caching algorithm by passing "[host]" to 711138032Speter hostsignature, which strips the square brackets and 711238032Speter returns the real name. This allows mailertable entries 711338032Speter to match regular entries. 711438032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 711538032Speter feature, even if it doesn't work right. 711638032Speter Catch and log attempts to try the "wiz" command in server SMTP. 711738032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 711838032Speter Be more generous at assigning $z to the home directory -- do this 711938032Speter for programs that are specified through a .forward file. 712038032Speter Fix from Andrew Chang of Sun Microsystems. 712138032Speter Always save a fatal error message in preference to a non-fatal 712238032Speter error message so that the "subject" line of return 712338032Speter messages is the best possible. 712438032Speter CONFIG: reduce the number of quotes needed to quote configuration 712538032Speter parameters with commas: two quotes should work now, e.g., 712638032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 712738032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 712838032Speter connections (domain-ized UUCP). 712938032Speter CONFIG: fix bug in default maps (-o must be before database file 713064562Sgshapiro name). Pointed out by Christophe Wolfhugel. 713138032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 713238032Speter DNS. This would presumably be used in UUCP islands. 713338032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 713438032Speter CONFIG: log $u in Received: line. This is in technical violation 713538032Speter of the standards, since it doesn't guarantee a domain 713638032Speter on the address. 713738032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 713838032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 713938032Speter the "m" flag should you want it. Apparently some Solaris 2.2 714038032Speter installations can't handle multiple local recipients. 714138032Speter Problem noted by Josh Smith. 714238032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 714338032Speter CONFIG: change default version level from 4 to 5. 714438032Speter CONFIG: add FEATURE(nullclient) to create a config file that 714538032Speter forwards all mail to a hub without ever looking at the 714638032Speter addresses in any detail. 714738032Speter CONFIG: properly strip mailer: information off of relays when 714838032Speter used to change .BITNET form into %-hack form. 714938032Speter CONFIG: fix a problem that caused infinite loops if presented 715038032Speter with an address such as "!foo". 715138032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 715238032Speter the reverse "PTR" mapping is broken. There's a better 715338032Speter way to do this, but the change is fairly major and I 715438032Speter want to hold it for another release. Problem noted by 715538032Speter Bret Marquis. 715638032Speter 715764562Sgshapiro8.5/8.5 1993/07/23 715838032Speter Serious bug: if you used a command line recipient that was unknown 715938032Speter sendmail would not send a return message (it was treating 716038032Speter everything as though it had an SMTP-style client that 716138032Speter would do the return itself). Problem noted by Josh Smith. 716238032Speter Change "trymx" option in getcanonname() to ignore all MX data, 716338032Speter even during a T_ANY query. This actually didn't break 716438032Speter anything, because the only time you called getcanonname 716538032Speter with !trymx was if you already knew there were no MX 716638032Speter records, but it is somewhat cleaner. From Motonori 716738032Speter Nakamura. 716838032Speter Don't call getcanonname from getmxrr if you already know there 716938032Speter are no DNS records matching the name. 717038032Speter Fix a problem causing error messages to always include "The 717138032Speter original message was received ... from localhost". 717238032Speter The correct original host information is now included. 717338032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 717438032Speter version of "test" doesn't have the -x flag). Change it 717538032Speter to use -f instead. From John Myers. 717638032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 717738032Speter esmtp -- it should be smtp. 717838032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 717938032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 718038032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 718138032Speter this cleans up the configs somewhat. This fixes a serious 718238032Speter problem that caused route-addrs to get mistaken as relays, 718338032Speter pointed out by John Myers. WARNING: this also causes 718438032Speter the default on SMART_HOST to change from "suucp" to 718538032Speter "relay" if you have MAILER(smtp) specified. 718638032Speter 718764562Sgshapiro8.4/8.4 1993/07/22 718838032Speter Add option `w'. If you receive a message that comes to you because 718938032Speter you are the best (lowest preference) target of an MX, and 719038032Speter you haven't explicitly recognized the source MX host in 719138032Speter your .cf file, this option will cause you to try the target 719238032Speter host directly (as if there were no MX for it at all). If 719338032Speter `w' is not set, this case is a configuration error. 719438032Speter Beware: if `w' is set, senders may get bogus errors like 719538032Speter "message timed out" or "host unknown" for problems that 719638032Speter are really configuration errors. This option is 719738032Speter disrecommended, provided only for compatibility with 719838032Speter UIUC sendmail. 719938032Speter Fix a problem that caused the incoming socket to be left open 720038032Speter when sendmail forks after the DATA command. This caused 720138032Speter calling systems to wait in FIN_WAIT_2 state until the 720238032Speter entire list was processed and the child closed -- a 720338032Speter potentially prodigious amount of time. Problem noted 720438032Speter by Neil Rickert. 720538032Speter Fix problem (created in 6.64) that caused mail sent to multiple 720638032Speter addresses, one of which was a bad address, to completely 720738032Speter suppress the sending of the message. This changes 720838032Speter handling of EF_FATALERRS somewhat, and adds an 720938032Speter EF_GLOBALERRS flag. This also fixes a potential problem 721038032Speter with duplicate error messages if there is a syntax error 721138032Speter in the header of a message that isn't noticed until late 721238032Speter in processing. Original problem pointed out by Josh Smith 721338032Speter of Harvey Mudd College. This release includes quite a bit 721438032Speter of dickering with error handling (see below). 721538032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 721638032Speter will only hurt already-broken software and should help 721738032Speter humans. 721838032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 721938032Speter compiled in. It would never read the alias file. 722038032Speter Repair unbalanced `)' and `>' (the "open" versions are already 722138032Speter repaired). 722238032Speter Logging of "done" in dropenvelope() was incorrect: it would 722338032Speter log this even when the queue file still existed. Change 722438032Speter this to only log "done" (at log level 11) when the 722538032Speter queue file is actually removed. From John Myers. 722638032Speter Log "lost connection" in server SMTP at log level 20 if there 722738032Speter is no pending transaction. Some senders just close the 722838032Speter connection rather than sending QUIT. 722938032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 723038032Speter domains that do not have MX records -- this would cause 723138032Speter the subsequent host name lookup to fail. The problem 723238032Speter only occurred if you had FEATURE(nocanonify) set. 723338032Speter Problem noted by Rick McCarty of Texas Instruments. 723438032Speter Fix invocation of setvbuf when passed a -X flag -- I had 723538032Speter unwittingly used an ANSI C extension, and this caused 723638032Speter core dumps on some machines. 723738032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 723838032Speter Previously it just gave an empty send queue, which 723938032Speter then gave either "Need RCPT (recipient)" at the DATA 724038032Speter (confusing, since you had given an RCPT command which 724138032Speter returned 250) or just dropped the email, depending on 724238032Speter whether you were running VERBose mode. Now it usually 724338032Speter diagnoses this case as "aliasing/forwarding loop broken". 724438032Speter Unfortunately, it still doesn't adequately diagnose 724538032Speter some true error conditions. 724638032Speter Add internal concept of "warning messages" using 6xx codes. 724738032Speter These are not reported only to Postmaster. Unbalanced 724838032Speter parens, brackets, and quotes are printed as 653 codes. 724938032Speter They are always mapped to 5xx codes before use in SMTP. 725038032Speter Clean up error messages to tell both the actual address that 725138032Speter failed and the alias they arose from. This makes it 725238032Speter somewhat easier to diagnose problems. Difficulty noted 725338032Speter by Motonori Nakamura. 725438032Speter Fix a problem that inappropriately added a ctladdr to addresses 725538032Speter that shouldn't have had one during a queue run. This 725638032Speter caused error messages to be handled differently during 725738032Speter a queue run than a direct run. 725838032Speter Don't print the qf name and line number if you get errors during 725938032Speter the direct run of the queue from srvrsmtp -- this was 726038032Speter just extra stuff for users to crawl through. 726138032Speter Put command line flags on second line of pid file so you can 726238032Speter auto-restart the daemon with all appropriate arguments. 726338032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 726438032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 726538032Speter restart it. 726638032Speter Remove the ``setuid(getuid())'' in main -- this caused the 726738032Speter IDENT daemon to screw up. This required that I change 726838032Speter HASSETEUID to HASSETREUID and complicate the mode 726938032Speter changing somewhat because both Ultrix and SunOS seem 727038032Speter to have a bug causing seteuid() to set the saved uid 727138032Speter as well as the effective. The program test/t_setreuid.c 727238032Speter will test to see if your implementation of setreuid(2) 727338032Speter is appropriately functional. 727438032Speter The FallBackMX (option V) handling failed to properly identify 727538032Speter fallback to yourself -- most of the code was there, 727638032Speter but it wasn't being enabled. Problem noted by Murray 727738032Speter Kucherawy of the University of Waterloo. 727838032Speter Change :include: open timeout from ETIMEDOUT to an internal 727938032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 728038032Speter with CurHostName" in error messages, which can be 728138032Speter confusing. Reported by Jonathan Kamens of OpenVision 728238032Speter Technologies. 728338032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 728438032Speter process group id. The original fix was to get around 728538032Speter some problems with recalcitrant MUAs, but it breaks 728638032Speter any call from a shell that creates a process group id 728738032Speter different from the process id. I could try to fix 728838032Speter this by diddling the tty owner (using tcsetpgrp or 728938032Speter equivalent) but this is too likely to break other 729038032Speter things. 729138032Speter Portability changes: 729238032Speter Support -M as equivalent to -oM on Ultrix -- apparently 729338032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 729438032Speter instead of using standard flags. Oh joy. This 729543730Speter behavior reported by Jon Giltner of University 729638032Speter of Colorado. 729738032Speter SGI IRIX -- this includes several changes that should 729838032Speter help other strict ANSI compilers. 729938032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 730038032Speter Corporation. 730138032Speter Solaris running the Sun C compiler (which despite the 730238032Speter documentation apparently doesn't define 730338032Speter __STDC__ by default). 730438032Speter ConvexOS from Eric Schnoebelen of Convex. 730538032Speter Sony NEWS workstations and Omron LUNA workstations from 730638032Speter Motonori Nakamura. 730738032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 730838032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 730938032Speter several people have made a good argument that this 731038032Speter creates more problems than it solves (although this 731138032Speter may prove painful in the short run). 731238032Speter CONFIG: generalize all the relays to accept a "mailer:host" 731338032Speter format. 731438032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 731538032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 731638032Speter addresses are also passed through this ruleset. 731738032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 731838032Speter internet-style addresses would "fall off the end" of 731938032Speter ruleset zero and be interpreted as local -- however, 732038032Speter the angle brackets confused the recursive call. 732138032Speter These are now diagnosed as "Unrecognized host name". 732238032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 732338032Speter ifdef(`_MAILER_USENET_') instead of 732438032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 732538032Speter of SINTEF RUNIT, Oslo. 732638032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 732738032Speter early in ruleset 0; this allows .mc authors to bypass 732838032Speter things like the "short circuit" code for local addresses. 732938032Speter Prompted by a comment by Bill Wisner of The Well. 733038032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 733138032Speter esmtp) to send SMTP mail. This allows you to default 733238032Speter to esmtp but use a mailertable or other override to 733338032Speter deal with broken servers. This logic was pointed out 733438032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 733538032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 733638032Speter environments. Ugly as sin. 733738032Speter 733864562Sgshapiro8.3/8.3 1993/07/13 733938032Speter Fix setuid problems introduced in 8.2 that caused messages 734038032Speter like "Cannot create qfXXXXXX: Invalid argument" 734138032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 734238032Speter involved a new compile flag "HASSETEUID" that takes 734338032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 734438032Speter that the POSIX interface is broken enough to break 734538032Speter some systems badly. This includes some fixes for 734638032Speter HP-UX. Also fixes problems where the real uid is 734738032Speter not reset properly on startup (from Neil Rickert). 734838032Speter Fix a problem that caused timed out messages to not report the 734938032Speter addresses that timed out. Error messages are also more 735038032Speter "user friendly". 735138032Speter Drop required bandwidth on connections from 64 bytes/sec to 735238032Speter 16 bytes/sec. 735338032Speter Further Solaris portability changes -- doesn't require the BSD 735438032Speter compatibility library. This also adds a new 735538032Speter "HASGETDTABLESIZE" compile flag which can be used if 735638032Speter you want to use getdtablesize(2) instead of sysconf(2). 735738032Speter These are loosely based on changes from David Meyer at 735838032Speter University of Oregon. This now seems to work, at least 735938032Speter for quick test cases. 736038032Speter Fix a problem that can cause duplicate error messages to be 736138032Speter sent if you are in SMTP, you send to multiple addresses, 736238032Speter and at least one of those addresses is good and points 736338032Speter to an account that has a .forward file (whew!). 736438032Speter Fix a problem causing messages to be discarded if checkcompat() 736538032Speter returned EX_TEMPFAIL (because it didn't properly mark 736638032Speter the "to" address). Problem noted by John Myers. 736738032Speter Fix dfopen to return NULL if the open failed; I was depending 736838032Speter on fdopen(-1) returning NULL, which isn't the case. This 736938032Speter isn't serious, but does result in weird error diagnoses. 737038032Speter From Michael Corrigan. 737138032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 737238032Speter messages sent through UUCP-family mailers. Suggested 737338032Speter by Bill Wisner of The Well. 737438032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 737538032Speter include a "uucp-dom" mailer that uses domain-style 737638032Speter addressing. Suggested by Bill Wisner. 737738032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 737838032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 737938032Speter Christophe Wolfhugel. 738038032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 738138032Speter 738264562Sgshapiro8.2/8.2 1993/07/11 738338032Speter Don't drop out on config file parse errors in -bt mode. 738438032Speter On older configuration files, assume option "l" (use Errors-To 738538032Speter header) for back compatibility. NOTE: this DOES NOT 738638032Speter imply an endorsement of the Errors-To: header in any way. 738738032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 738838032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 738938032Speter SMTP server to give an error on this command, and 739038032Speter logging it in the transcript can be confusing. Fix 739138032Speter from Bill Wisner. 739238032Speter IRIX compatibility changes provided by Dan Rich 739338032Speter <drich@sandman.lerc.nasa.gov>. 739438032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 739538032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 739638032Speter <juo@klinzhai.rutgers.edu> 739738032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 739838032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 739938032Speter match the other flags in that file. 740038032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 740138032Speter Save h_errno in mci struct and improve error message display. 740238032Speter Changes from Eric Wassenaar. 740338032Speter Open /dev/null for the transcript if the create of the xf file 740438032Speter failed; this avoids at least one possible null pointer 740538032Speter reference in very weird cases. From Eric Wassenaar. 740638032Speter Clean up statistics gathering; it was over-reporting because of 740738032Speter forks. From Eric Wassenaar. 740838032Speter Fix problem that causes old Return-Path: line to override new 740938032Speter Return-Path: line (conf.c needs H_FORCE to avoid 741038032Speter re-using old value). From Motonori Nakamura. 741138032Speter Fix broken -m flag in K definition -- even if -m (match only) 741238032Speter was specified, it would still replace the key with the 741338032Speter value. Noted by Rick McCarty of Texas Instruments. 741438032Speter If the name server timed out over several days, no "timed out" 741538032Speter message would ever be sent back. The timeout code 741638032Speter has been moved from markfailure() to dropenvelope() 741738032Speter so that all such failures should be diagnosed. Pointed 741838032Speter out by Christophe Wolfhugel and others. 741938032Speter Relax safefile() constraints: directories in an include or 742038032Speter forward path must be readable by self if the controlling 742138032Speter user owns the entry, readable by all otherwise (e.g., 742238032Speter when reading your .forward file, you have to own and 742338032Speter have X permission in it; everyone needs X permission in 742438032Speter the root and directories leading up to your home); 742538032Speter include files must be readable by anyone, but need not 742638032Speter be owned by you. 742738032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 742838032Speter reading a .forward file; this gets around some problems 742938032Speter on NFS mounts if root permission is not exported and 743038032Speter the user's home directory isn't x'able. 743138032Speter Additional NeXT portability enhancements from Axel Zinser. 743238032Speter Additional HP-UX portability enhancements from Brian Bullen. 743338032Speter Add a timeout around SMTP message writes; this assumes you can 743438032Speter get throughput of at least 64 bytes/second. Note that 743538032Speter this does not impact the "datafinal" default, which 743638032Speter is separate; this is just intended to work around 743738032Speter network clogs that will occur before the final dot 743838032Speter is sent. From Eric Wassenaar. 743938032Speter Change map code to set the "include null" flag adaptively -- 744038032Speter it initially tries both, but if it finds anything 744138032Speter matching without a null it never tries again with a 744238032Speter null and vice versa. If -N is specified, it never 744338032Speter tries without the null and creates new maps with a 744438032Speter null byte. If -O is specified, it never tries with 744538032Speter the null (for efficiency). If -N and -O are specified, 744638032Speter you get -NO (get it?) lookup at all, so this would 744738032Speter be a bad idea. If you don't specify either -N or -O, 744838032Speter it adapts. 744938032Speter Fix recognition of "same from address" so that MH submissions 745038032Speter will insert the appropriate full name information; 745138032Speter this used to work and got broken somewhere along the 745238032Speter way. 745338032Speter Some changes to eliminate some unnecessary SYSERRs in the 745438032Speter log. For example, if you lost a connection, don't 745538032Speter bother reporting that fact on the connection you lost. 745638032Speter Add some "extended debugging" flags to try to track down 745738032Speter why we get occasional problems with file descriptor 745838032Speter one being closed when execing a mailer; it seems to 745938032Speter only happen when there has been another error in the 746038032Speter same transaction. This requires XDEBUG, defined 746138032Speter by default in conf.h. 746238032Speter Add "-X filename" command line flag, which logs both sides of 746338032Speter all SMTP transactions. This is intended ONLY for 746438032Speter debugging bad implementations of other mailers; start 746538032Speter it up, send a message from a mailer that is failing, 746638032Speter and then kill it off and examine the indicated log. 746738032Speter This output is not intended to be particularly human 746838032Speter readable. This also adds the HASSETVBUF compile 746938032Speter flag, defaulted on if your compiler defines __STDC__. 747038032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 747138032Speter have a local net that should get direct connects, you 747238032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 747338032Speter See cf/README for an example. 747438032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 747538032Speter sites that don't use the -d flag. 747638032Speter CONFIG: hide recipient addresses as well as sender addresses 747738032Speter behind $M if FEATURE(allmasquerade) is specified; this 747838032Speter has been requested by several people, but can break 747938032Speter local aliases. For example, if you mail to "localalias" 748038032Speter this will be rewritten as "localalias@masqueradehost"; 748138032Speter although initial delivery will work, replies will be 748238032Speter broken. Use it sparingly. 748338032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 748438032Speter to qualified domains in headers. I believe this is 748538032Speter largely equivalent to the IDA feature of the same name. 748638032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 748738032Speter to override the "system name" as your UUCP name -- 748838032Speter in particular, to use domain-ized UUCP names. From 748938032Speter Bill Wisner of The Well. 749038032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 749138032Speter first. This is currently unused in the config files, 749238032Speter but could be used in a mailertable entry. 749338032Speter 749464562Sgshapiro8.1C/8.1B 1993/06/27 749538032Speter Serious security bug fix: it was possible to read any file on 749638032Speter the system, regardless of ownership and permissions. 749738032Speter If a subroutine returns a fully qualified address, return it 749838032Speter immediately instead of feeding it back into rewriting. 749938032Speter This fixes a problem with mailertable lookups. 750038032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 750138032Speter 750264562Sgshapiro8.1B/8.1A 1993/06/12 750338032Speter Serious bug fix: pattern matching backup algorithm stepped by 750438032Speter two tokens in classes instead of one. Found by Claus 750538032Speter Assmann at University of Kiel, Germany. 750638032Speter 750764562Sgshapiro8.1A/8.1A 1993/06/08 750838032Speter Another mailertable fix.... 750938032Speter 751064562Sgshapiro8.1/8.1 1993/06/07 751138032Speter 4.4BSD freeze.
