Audit 1271345Sgshapiro other array indexing. This bug is not believed to be 1371345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 1471345Sgshapiro Schools" project (IdS). 1571345Sgshapiro Add an FFR (for future release) to drop privileges when using 1671345Sgshapiro address test mode. This will be turned on in 8.12. It can 1771345Sgshapiro be enabled by compiling with: 1871345Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 1971345Sgshapiro in your devtools/Site/site.config.m4 file. Suggested by 2071345Sgshapiro Michal Zalewski of the "Internet for Schools" project (IdS). 2171345Sgshapiro Fix potential problem with Cyrus-SASL security layer which may have 2271345Sgshapiro caused I/O errors, especially for mechanism DIGEST-MD5. 2371345Sgshapiro When QueueSortOrder was set to host, sendmail might not read 2471345Sgshapiro enough of the queue file to determine the host, making the 2571345Sgshapiro sort sub-optimal. Problem noted by Jeff Earickson of 2671345Sgshapiro Colby College. 2771345Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 2871345Sgshapiro RFC 1891) but don't have FAILURE as value. 2971345Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 3071345Sgshapiro This implies that every change to SASL related files requires 3171345Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 3271345Sgshapiro mechanisms (in form of shared libraries). 3371345Sgshapiro Properly set the STARTTLS related macros during a queue run for 3471345Sgshapiro a cached connection. Bug reported by Michael Kellen of 3571345Sgshapiro NxNetworks, Inc. 3671345Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 3771345Sgshapiro client name. 3871345Sgshapiro Include original length of bad field/header when reporting 3971345Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 4071345Sgshapiro the Universitat Regensburg. 4171345Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 4271345Sgshapiro DeliveryMode queue. Problem noted by Ric Anderson of the 4371345Sgshapiro University of Arizona. 4471345Sgshapiro Fix LDAP map -m (match only) flag. Problem noted by Jeff Giuliano 4571345Sgshapiro of Collective Technologies. 4671345Sgshapiro Avoid using a negative argument for sleep() calls when delaying answers 4771345Sgshapiro to EXPN/VRFY commands on systems which respond very slowly. 4871345Sgshapiro Problem noted by Mikolaj J. Habryn of Optus Internet 4971345Sgshapiro Engineering. 5071345Sgshapiro Make sure the F=u flag is set in the default prog mailer 5171345Sgshapiro definition. Problem noted by Kari Hurtta of the Finnish 5271345Sgshapiro Meteorological Institute. 5371345Sgshapiro Fix IPv6 check for unspecified addresses. Patch from 5471345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 5571345Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 5671345Sgshapiro Meteorological Institute. 5771345Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 5871345Sgshapiro of the parameters to find Family= setting before trying to 5971345Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 6071345Sgshapiro Kletnieks of Virginia Tech. 6171345Sgshapiro When delivering to a file directly from an alias, do not call 6271345Sgshapiro initgroups(); instead use the DefaultUser group information. 6371345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 6471345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 6571345Sgshapiro created. Otherwise, sendmail can not remove it upon 6671345Sgshapiro close. Problem noted by Werner Wiethege. 6771345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 6871345Sgshapiro overall connections, not the number of connections per 6971345Sgshapiro socket. A future version may change this to per socket 7071345Sgshapiro counting. 7171345Sgshapiro Portability: 7271345Sgshapiro Clean up libsmdb so it functions properly on platforms 7371345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t). Problem 7471345Sgshapiro noted by Rein Tollevik of Basefarm AS. 7571345Sgshapiro Fix man page formatting for compatibility with Solaris' 7671345Sgshapiro whatis. From Stephen Gildea of InTouch Systems, Inc. 7771345Sgshapiro UnixWare 7 includes snprintf() support. From Larry 7871345Sgshapiro Rosenman. 7971345Sgshapiro IPv6 changes for platforms using KAME. Patch from 8071345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 8171345Sgshapiro Avoid a typedef compile conflict with Berkeley DB 3.X and 8271345Sgshapiro Solaris 2.5 or earlier. Problem noted by Bob Hughes 8371345Sgshapiro of Pacific Access. 8471345Sgshapiro Add preliminary support for AIX 5. Contributed by 8571345Sgshapiro Valdis Kletnieks of Virginia Tech. 8671345Sgshapiro Solaris 9 load average support from Andrew Tucker of Sun 8771345Sgshapiro Microsystems. 8871345Sgshapiro CONFIG: Reject addresses of the form a!b if FEATURE(`nouucp', `r') 8971345Sgshapiro is used. Problem noted by Phil Homewood of Asia Online, 9071345Sgshapiro patch from Neil Rickert of Northern Illinois University. 9171345Sgshapiro CONFIG: Change the default DNS based blacklist server for 9271345Sgshapiro FEATURE(`dnsbl') to blackholes.mail-abuse.org. 9371345Sgshapiro CONFIG: Deal correctly with the 'C' flag in {daemon_flags}, i.e., 9471345Sgshapiro implicitly assume canonical host names. 9571345Sgshapiro CONFIG: Deal with "::" in IPv6 addresses for access_db. Based on 9671345Sgshapiro patch by Motonori Nakamura of Kyoto University. 9771345Sgshapiro CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of 9871345Sgshapiro Virginia Tech. 9971345Sgshapiro CONFIG: Pass the illegal header form <list:;> through untouched 10071345Sgshapiro instead of making it worse. Problem noted by Motonori 10171345Sgshapiro Nakamura of Kyoto University. 10271345Sgshapiro CONTRIB: Added buildvirtuser (see `perldoc contrib/buildvirtuser`). 10371345Sgshapiro CONTRIB: qtool.pl: An empty queue is not an error. Problem noted 10471345Sgshapiro by Jan Krueger of digitalanswers communications consulting 10571345Sgshapiro gmbh. 10671345Sgshapiro CONTRIB: domainmap.m4: Handle domains with '-' in them. From Mark 10771345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 10871345Sgshapiro DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4 10971345Sgshapiro variables into bldOS, bldREL, and bldARCH to prevent 11071345Sgshapiro namespace collisions. Problem noted by Motonori Nakamura 11171345Sgshapiro of Kyoto University. 11271345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 11371345Sgshapiro causes some changes in behavior and may break rmail for 11471345Sgshapiro installations where sendmail is actually a wrapper to 11571345Sgshapiro another MTA. The change will re-appear in a future 11671345Sgshapiro version. 11771345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 11871345Sgshapiro and SunOS 5.8. Requested by Jeff A. Earickson of Colby 11971345Sgshapiro College and John Beck of Sun Microsystems. 12071345Sgshapiro VACATION: Fix pattern matching for addresses to ignore. 12171345Sgshapiro VACATION: Don't reply to addresses of the form owner-* 12271345Sgshapiro or *-owner. 12371345Sgshapiro New Files: 12471345Sgshapiro cf/ostype/aix5.m4 12571345Sgshapiro contrib/buildvirtuser 12671345Sgshapiro devtools/OS/AIX.5.0 12771345Sgshapiro 12866494Sgshapiro8.11.1/8.11.1 2000/09/27 12966494Sgshapiro Fix SMTP EXPN command output if the address expands to a single 13066494Sgshapiro name. Fix from John Beck of Sun Microsystems. 13166494Sgshapiro Don't try STARTTLS in the client if the PRNG has not been properly 13266494Sgshapiro seeded. This problem only occurs on systems without 13366494Sgshapiro /dev/urandom. Problem detected by Jan Krueger of 13466494Sgshapiro digitalanswers communications consulting gmbh and 13566494Sgshapiro Neil Rickert of Northern Illinois University. 13666494Sgshapiro Don't use the . and .. directories when expanding QueueDirectory 13766494Sgshapiro wildcards. 13866494Sgshapiro Do not try to cache LDAP connections across processes as a parent 13966494Sgshapiro process may close the connection before the child process 14066494Sgshapiro has completed. Problem noted by Lai Yiu Fai of the Hong 14166494Sgshapiro Kong University of Science and Technology and Wolfgang 14266494Sgshapiro Hottgenroth of UUNET. 14366494Sgshapiro Use Timeout.fileopen to limit the amount of time spent trying to 14466494Sgshapiro read the LDAP secret from a file. 14566494Sgshapiro Prevent SIGTERM from removing a command line submitted item after 14666494Sgshapiro the user submits the message and before the first delivery 14766494Sgshapiro attempt completes. Problem noted by Max France of AlphaNet. 14866494Sgshapiro Fix from Neil Rickert of Northern Illinois University. 14966494Sgshapiro Deal correctly with MaxMessageSize restriction if message size is 15071345Sgshapiro greater than 2^31. Problem noted by Tim "Darth Dice" Bosserman 15171345Sgshapiro of EarthLink. 15266494Sgshapiro Turn off queue checkpointing if CheckpointInterval is set to zero. 15366494Sgshapiro Treat an empty home directory (from getpw*() or $HOME) as 15466494Sgshapiro non-existent instead of treating it as /. Problem noted by 15566494Sgshapiro Todd C. Miller of Courtesan Consulting. 15666494Sgshapiro Don't drop duplicate headers when reading a queued item. Problem 15766494Sgshapiro noted by Motonori Nakamura of Kyoto University. 15866494Sgshapiro Avoid bogus error text when logging the savemail panic "cannot 15966494Sgshapiro save rejected email anywhere". Problem noted by Marc G. 16066494Sgshapiro Fournier of Acadia University. 16166494Sgshapiro If an LDAP search fails because the LDAP server went down, close 16266494Sgshapiro the map so subsequent searches reopen the map. If there are 16366494Sgshapiro multiple LDAP servers, the down server will be skipped and 16466494Sgshapiro one of the others may be able to take over. 16566494Sgshapiro Set the ${load_avg} macro to the current load average, not the 16666494Sgshapiro previous load average query result. 16766494Sgshapiro If a non-optional map used in a check_* ruleset can't be opened, 16866494Sgshapiro return a temporary failure to the remote SMTP client 16966494Sgshapiro instead of ignoring the map. Problem noted by Allan E 17066494Sgshapiro Johannesen of Worcester Polytechnic Institute. 17166494Sgshapiro Avoid a race condition when queuing up split envelopes by saving 17266494Sgshapiro the split envelopes before the original envelope. 17366494Sgshapiro Fix a bug in the PH_MAP code which caused mail to bounce instead of 17466494Sgshapiro defer if the PH server could not be contacted. From Mark 17566494Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 17666494Sgshapiro Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and 17766494Sgshapiro ETRN. Problem noted by Erik R. Leo of SoVerNet. 17866494Sgshapiro Change error code for unrecognized parameters to the SMTP MAIL and 17966494Sgshapiro RCPT commands from 501 to 555 per RFC 1869. Problem 18066494Sgshapiro reported to Postfix by Robert Norris of Monash University. 18166494Sgshapiro Prevent overwriting the argument of -B on certain OS. Problem 18266494Sgshapiro noted by Matteo Gelosa of I.NET S.p.A. 18366494Sgshapiro Use the proper routine for freeing memory with Netscape's LDAP 18466494Sgshapiro client libraries. Patch from Paul Hilchey of the 18566494Sgshapiro University of British Columbia. 18666494Sgshapiro Portability: 18766494Sgshapiro Move the NETINET6 define to devtools/OS/SunOS.5.{8,9} 18866494Sgshapiro instead of defining it in conf.h so users can 18966494Sgshapiro override the setting. Suggested by 19066494Sgshapiro Henrik Nordstrom of Ericsson. 19166494Sgshapiro On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of 19266494Sgshapiro /usr/lib/sendmail for rmail and vacation. From 19366494Sgshapiro Jeff A. Earickson of Colby College. 19466494Sgshapiro On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which 19566494Sgshapiro does not exist). From Jeff A. Earickson of Colby 19666494Sgshapiro College. 19766494Sgshapiro Avoid using the UCB subsystem on NCR MP-RAS 3.x. From 19866494Sgshapiro Tom Moore of NCR. 19966494Sgshapiro NeXT 3.X and 4.X installs man pages in /usr/man. From 20066494Sgshapiro Hisanori Gogota of NTT/InterCommunicationCenter. 20166494Sgshapiro Solaris 8 and later include /var/run. The default PID file 20266494Sgshapiro location is now /var/run/sendmail.pid. From John 20366494Sgshapiro Beck of Sun Microsystems. 20466494Sgshapiro SFIO includes snprintf() for those operating systems 20566494Sgshapiro which do not. From Todd C. Miller of Courtesan 20666494Sgshapiro Consulting. 20766494Sgshapiro CONFIG: Use the result of _CERT_REGEX_SUBJECT_ not {cert_subject}. 20866494Sgshapiro Problem noted by Kaspar Brand of futureLab AG. 20966494Sgshapiro CONFIG: Change 553 SMTP reply code to 501 to avoid problems with 21066494Sgshapiro errors in the MAIL address. 21166494Sgshapiro CONFIG: Fix FEATURE(nouucp) usage in example .mc files. Problem 21266494Sgshapiro noted by Ron Jarrell of Virginia Tech. 21366494Sgshapiro CONFIG: Add support for Solaris 8 (and later) as OSTYPE(solaris8). 21466494Sgshapiro Contributed by John Beck of Sun Microsystems. 21566494Sgshapiro CONFIG: Set confFROM_HEADER such that the mail hub can possibly add 21666494Sgshapiro GECOS information for an address. This more closely 21766494Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 21866494Sgshapiro Ericsson. 21966494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 22066494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 22166494Sgshapiro mailer as described in cf/README. 22266494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 22366494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 22466494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 22566494Sgshapiro makemap to 'unmake' the map. 22666494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 22766494Sgshapiro sendmail. 22866494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 22966494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 23066494Sgshapiro Meteorological Institute. 23166494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 23266494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 23366494Sgshapiro dot as the only character on the line. 23466494Sgshapiro New Files: 23566494Sgshapiro cf/ostype/solaris8.m4 23666494Sgshapiro 23764562Sgshapiro8.11.0/8.11.0 2000/07/19 23864562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 23964562Sgshapiro (not the normal case), some operating systems will still 24064562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 24164562Sgshapiro to drop all of its privileges. If sendmail needs to drop 24264562Sgshapiro these privileges and the operating system doesn't set the 24364562Sgshapiro saved-uid as well, exit with an error. Problem noted by 24464562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 24564562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 24664562Sgshapiro it populates. It is possible that some broken 24764562Sgshapiro implementations of snprintf() exist that do not do this. 24864562Sgshapiro Systems in this category should compile with 24964562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 25064562Sgshapiro system and report broken implementations to 25164562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 25264562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 25364562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 25464562Sgshapiro Implementation influenced by the example programs of 25564562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 25664562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 25764562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 25864562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 25964562Sgshapiro cf/README and doc/op/op.*. 26064562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 26164562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 26264562Sgshapiro ${server_name}, and ${server_addr}. These are documented 26364562Sgshapiro in cf/README and doc/op/op.*. 26464562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 26564562Sgshapiro random data. 26664562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 26764562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 26864562Sgshapiro try to use STARTTLS despite the security problems. 26964562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 27064562Sgshapiro support encryption. Based on code contributed by Tim 27164562Sgshapiro Martin of CMU. 27264562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 27364562Sgshapiro strength factor. 27464562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 27564562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 27664562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 27764562Sgshapiro of CMU. 27864562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 27964562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 28064562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 28164562Sgshapiro Fix the default family selection for DaemonPortOptions. As 28264562Sgshapiro documented, unless a family is specified in a 28364562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 28464562Sgshapiro also the default if no DaemonPortOptions value is set. 28564562Sgshapiro Therefore, IPv6 users should configure additional sockets 28664562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 28764562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 28864562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 28964562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 29064562Sgshapiro the interface information for an outgoing connection. 29164562Sgshapiro Not doing so was creating a mismatch between the socket 29264562Sgshapiro family and address used in subsequent connections if the 29364562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 29464562Sgshapiro by John Beck of Sun Microsystems. 29564562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 29664562Sgshapiro family based on the IP address. ${if_family} is no longer 29764562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 29864562Sgshapiro of Sun Microsystems. 29964562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 30064562Sgshapiro macros for both the incoming interface address/family and 30164562Sgshapiro the outgoing interface address/family. In order for M=b 30264562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 30364562Sgshapiro the incoming information in the queue file for later 30464562Sgshapiro delivery attempts. 30564562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 30664562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 30764562Sgshapiro smoe.org. 30864562Sgshapiro Add more vigilance in checking for putc() errors on output streams 30964562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 31064562Sgshapiro noted by Graeme Hewson of Oracle. 31164562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 31264562Sgshapiro Problem noted by Ajay Matia. 31364562Sgshapiro Under certain circumstances, an address could be listed as deferred 31464562Sgshapiro but would be bounced back to the sender as failed to be 31564562Sgshapiro delivered when it really should have been queued. Problem 31664562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 31764562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 31864562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 31964562Sgshapiro Hedeland of Ericsson. 32064562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 32164562Sgshapiro is defined to avoid a core dump due to incompatibilities 32264562Sgshapiro between sfio and stdio.

XUSR may disappear from a future release. 65364562Sgshapiro The new '-G' (relay (gateway) submission) command line option 65464562Sgshapiro indicates that the message being submitted from the command 65564562Sgshapiro line is for relaying, not initial submission. This means 65664562Sgshapiro the message will be rejected if the addresses are not fully 65764562Sgshapiro qualified and no canonicalization will be done. Future 65864562Sgshapiro releases may even reject improperly formed messages. 65964562Sgshapiro The '-U' (initial user submission) command line option is 66064562Sgshapiro deprecated and may be removed from a future release. 66164562Sgshapiro Mail user agents should begin using '-G' to indicate that 66264562Sgshapiro this is a relay submission (the inverse of -U). 66364562Sgshapiro The next release of sendmail will assume that any message submitted 66464562Sgshapiro from the command line is an initial user submission and act 66564562Sgshapiro accordingly. 66664562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 66764562Sgshapiro program or deliver to file as the owner of that file, the 66864562Sgshapiro address is marked as unsafe. This means if RunAsUser is 66964562Sgshapiro set, users won't be able to use programs or delivery to 67064562Sgshapiro files in their .forward files. Administrators can override 67164562Sgshapiro this by setting the DontBlameSendmail option to the new 67264562Sgshapiro setting NonRootSafeAddr. 67364562Sgshapiro Allow group or world writable directories if the sticky bit is set 67464562Sgshapiro on the directory and DontBlameSendmail is set to 67564562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 67664562Sgshapiro InCert Software. 67764562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 67864562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 67964562Sgshapiro set in the DontBlameSendmail option. Requested by many. 68064562Sgshapiro New Timeout.control option to limit the total time spent satisfying 68164562Sgshapiro a control socket request. 68264562Sgshapiro New Timeout.resolver options for controlling BIND resolver 68364562Sgshapiro settings: 68464562Sgshapiro Timeout.resolver.retrans 68564562Sgshapiro Sets the resolver's retransmission time interval (in 68664562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 68764562Sgshapiro and Timeout.resolver.retrans.normal. 68864562Sgshapiro Timeout.resolver.retrans.first 68964562Sgshapiro Sets the resolver's retransmission time interval (in 69064562Sgshapiro seconds) for the first attempt to deliver a message. 69164562Sgshapiro Timeout.resolver.retrans.normal 69264562Sgshapiro Sets the resolver's retransmission time interval (in 69364562Sgshapiro seconds) for all resolver lookups except the first 69464562Sgshapiro delivery attempt. 69564562Sgshapiro Timeout.resolver.retry 69664562Sgshapiro Sets the number of times to retransmit a resolver 69764562Sgshapiro query. Sets both Timeout.resolver.retry.first 69864562Sgshapiro and Timeout.resolver.retry.normal. 69964562Sgshapiro Timeout.resolver.retry.first 70064562Sgshapiro Sets the number of times to retransmit a resolver 70164562Sgshapiro query for the first attempt to deliver a message. 70264562Sgshapiro Timeout.resolver.retry.normal 70364562Sgshapiro Sets the number of times to retransmit a resolver 70464562Sgshapiro query for all resolver lookups except the first 70564562Sgshapiro delivery attempt. 70664562Sgshapiro Contributed by Exactis.com, Inc. 70764562Sgshapiro Support multiple queue directories. To use multiple queues, supply 70864562Sgshapiro a QueueDirectory option value ending with an asterisk. For 70964562Sgshapiro example, /var/spool/mqueue/q* will use all of the 71064562Sgshapiro directories or symbolic links to directories beginning with 71164562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 71264562Sgshapiro mind, the queue directory structure should not be changed 71364562Sgshapiro while sendmail is running. Queue runs create a separate 71464562Sgshapiro process for running each queue unless the verbose flag is 71564562Sgshapiro given on a non-daemon queue run. New items are randomly 71664562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 71764562Sgshapiro Support different directories for qf, df, and xf queue files; if 71864562Sgshapiro subdirectories or symbolic links to directories of those names 71964562Sgshapiro exist in the queue directories, they are used for the 72064562Sgshapiro corresponding queue files. Keep in mind, the queue 72164562Sgshapiro directory structure should not be changed while sendmail is 72264562Sgshapiro running. Proposed by Mathias Koerber of Singapore 72364562Sgshapiro Telecommunications Ltd. 72464562Sgshapiro New queue file naming system which uses a filename guaranteed to be 72564562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 72664562Sgshapiro without fancy file system locking. Queued items can be 72764562Sgshapiro moved between queues easily.

This can be used with LMTP 75264562Sgshapiro local delivery agents which listen on a named socket. An 75364562Sgshapiro example mailer might be: 75464562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 75564562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 75664562Sgshapiro A=FILE /var/run/lmtpd 75764562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 75864562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 75964562Sgshapiro instead. 76064562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 76164562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 76264562Sgshapiro connections), IPC (which will be deprecated in a future 76364562Sgshapiro version), and FILE (for UNIX domain socket delivery). 76464562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 76564562Sgshapiro flags. 76664562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 76764562Sgshapiro body of the original message on delivery status 76864562Sgshapiro notifications. 76964562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 77064562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 77164562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 77264562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 77364562Sgshapiro Steve Schweinhart of America Online. 77464562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 77564562Sgshapiro not be set after rulesets are defined. Suggested by 77664562Sgshapiro Mitchell Blank Jr of Exec-PC. 77764562Sgshapiro Do not report temporary failure on delivery to files. In 77864562Sgshapiro interactive delivery mode, this would result in two SMTP 77964562Sgshapiro responses after the DATA command. Problem noted by 78064562Sgshapiro Nik Conwell of Boston University. 78164562Sgshapiro Check file close when mailing to files.

Fix from Raj Kunjithapadam of 78764562Sgshapiro @Home Network. 78864562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 78964562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 79064562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 79164562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 79264562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 79364562Sgshapiro similar to check_rcpt etc. 79464562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 79564562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 79664562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 79764562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 79864562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 79964562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 80064562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 80164562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 80264562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 80364562Sgshapiro the corresponding DSN parameter values. Proposed by 80464562Sgshapiro Mathias Herberts. 80564562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 80664562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 80764562Sgshapiro before the message has been collected, thereafter it holds 80864562Sgshapiro the message size as computed by sendmail (and can be used 80964562Sgshapiro in check_compat). 81064562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 81164562Sgshapiro sendmail is using instead of the value of the DeliveryMode 81264562Sgshapiro option. 81364562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 81464562Sgshapiro Drop explicit From: if same as what would be generated only if it is 81564562Sgshapiro a local address.

Mongiovi of Georgia Tech. 81864562Sgshapiro Log "low on disk space" only when necessary. 81964562Sgshapiro New macro ${load_avg} can be used to check the current load average. 82064562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 82164562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 82264562Sgshapiro is set. 82364562Sgshapiro Flag -S for maps to specify the character which is substituted 82464562Sgshapiro for spaces (instead of the default given by O BlankSub). 82564562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 82664562Sgshapiro This flag is set by default for the host map. Based on a 82764562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 82864562Sgshapiro Open maps only on demand, not at startup. 82964562Sgshapiro Log warning about unsupported IP address families. 83064562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 83164562Sgshapiro of the sum of all headers. This can be used to prevent 83264562Sgshapiro a denial-of-service attack. 83364562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 83464562Sgshapiro headers and parameters within those headers. This option 83564562Sgshapiro is intended to protect mail user agents from buffer 83664562Sgshapiro overflow attacks. 83764562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 83864562Sgshapiro alias recursion. 83964562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 84064562Sgshapiro Map type syslog to log the key via syslogd. 84164562Sgshapiro Entries in the alias file can be continued by putting a backslash 84264562Sgshapiro directly before the newline. 84364562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 84464562Sgshapiro dead.letter file, formerly hardcoded to 84564562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 84664562Sgshapiro default), sendmail will not attempt to save to a 84764562Sgshapiro system-wide dead.letter file if it can not bounce the mail 84864562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 84964562Sgshapiro file as it has in the past when the dead.letter file 85064562Sgshapiro could not be opened. 85164562Sgshapiro New option PidFile to define the location of the pid file. The 85264562Sgshapiro value of this option is macro expanded. 85364562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 85464562Sgshapiro process title shown in 'ps' listings. 85564562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 85664562Sgshapiro (along with the already existing macros): 85764562Sgshapiro ${daemon_info} Daemon information, e.g. 85864562Sgshapiro SMTP+queueing@00:30:00 85964562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 86064562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 86164562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 86264562Sgshapiro ${daemon_port} Daemon port, e.g., 25 86364562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 86464562Sgshapiro New macros especially for virtual hosting: 86564562Sgshapiro ${if_name} hostname of interface of incoming connection. 86664562Sgshapiro ${if_addr} address of interface of incoming connection. 86764562Sgshapiro The latter is only set if the interface does not belong to the 86864562Sgshapiro loopback net. 86964562Sgshapiro If a message being accepted via a method other than SMTP and 87064562Sgshapiro would be rejected by a header check, do not send the message. 87164562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 87264562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 87364562Sgshapiro Provide header value as quoted string in the macro 87464562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 87564562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 87664562Sgshapiro The length of the header value is stored in ${hdrlen}. 87764562Sgshapiro H*: allows to specify a default ruleset for header checks. This 87864562Sgshapiro ruleset will only be called if the individual header does 87964562Sgshapiro not have its own ruleset assigned. Suggested by Jan 88064562Sgshapiro Krueger of Unix-AG of University of Hannover. 88164562Sgshapiro The name of the header field stored in ${hdr_name}. 88264562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 88364562Sgshapiro removed if the config file version is greater than or equal 88464562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 88564562Sgshapiro input "token (1)" but does not match "token". 88664562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 88764562Sgshapiro MIME messages.

Problem noted by Chris Adams 89664562Sgshapiro of Renaissance Internet Services. 89764562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 89864562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 89964562Sgshapiro queue up the message instead of bouncing it. 90064562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 90164562Sgshapiro standard does not provide any indication of what to do when 90264562Sgshapiro something other than 250 is received. Based on a patch 90364562Sgshapiro from Steve Schweinhart of America Online. 90464562Sgshapiro New option TrustedUser allows to specify a user who can own 90564562Sgshapiro important files instead of root. This requires HASFCHOWN. 90664562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 90764562Sgshapiro setting USERDB=0 works.

Suggested by Igor Vinokurov. 91664562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 91764562Sgshapiro mailer to return after sending all data to it. 91864562Sgshapiro Only free memory from the process list when adding a new process 91964562Sgshapiro into a previously filled slot. Previously, the memory was 92064562Sgshapiro freed at removal time. Since removal can happen in a 92164562Sgshapiro signal handler, this may leave the memory map in an 92264562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 92364562Sgshapiro David Cooley of Colby College. 92464562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 92564562Sgshapiro local users in the passwd file. The UserDB code has 92664562Sgshapiro already decided the message will be passed to another host 92764562Sgshapiro for processing. Fix from Tony Landells of Burdett 92864562Sgshapiro Buckeridge Young Limited. 92964562Sgshapiro Support LDAP authorization via either a file containing the 93064562Sgshapiro password or Kerberos V4 using the new map options 93164562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 93264562Sgshapiro distinguished_name is who to login as. The method can be 93364562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 93464562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 93564562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 93664562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 93764562Sgshapiro of Stanford University. 93864562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 93964562Sgshapiro deprecated and will be removed in a future version. 94064562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 94164562Sgshapiro and the map has the column delimiter set, it turns that 94264562Sgshapiro response into a delimiter separated string. The LDAP map 94364562Sgshapiro will traverse multiple entries as well. LDAP alias maps 94464562Sgshapiro automatically set the column delimiter to the comma. 94564562Sgshapiro Based on patch from Booker Bense of Stanford University and 94664562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 94764562Sgshapiro Support return of multiple values for a single LDAP lookup. The 94864562Sgshapiro values to be returned should be in a comma separated string. 94964562Sgshapiro For example, `-v "email,emailother"'. Patch from 95064562Sgshapiro Curtis W. Hillegas of Princeton University. 95164562Sgshapiro Allow the use of LDAP for alias maps. 95264562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 95364562Sgshapiro attributes found in the match will be returned. 95464562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 95564562Sgshapiro breaking up a single entry into multiple entries. This is 95664562Sgshapiro needed for LDAP alias file specifications to allow for 95764562Sgshapiro comma separated key and value strings. 95864562Sgshapiro Keep connections to LDAP server open instead of opening and closing 95964562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 96064562Sgshapiro connections such that multiple maps which use the same 96164562Sgshapiro host, port, bind DN, and authentication will only result in 96264562Sgshapiro a single connection to that host. 96364562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 96464562Sgshapiro Be more careful about checking for errors and freeing memory on 96564562Sgshapiro LDAP lookups. 96664562Sgshapiro Use asynchronous LDAP searches to save memory and network 96764562Sgshapiro resources. 96864562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 96964562Sgshapiro Increase portability to the Netscape LDAP libraries. 97064562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 97164562Sgshapiro replaced with the literal contents of the map lookup key -- 97264562Sgshapiro note that this means a lookup can be done using the LDAP 97364562Sgshapiro special characters. The new '%0' token can be used instead 97464562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 97564562Sgshapiro For example, if the LDAP map specification contains '-k 97664562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 97764562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 97864562Sgshapiro user attribute. Instead, if the LDAP map specification 97964562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 98064562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 98164562Sgshapiro with the name "*". 98264562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 98364562Sgshapiro more than one is returned, it is equivalent to no records 98464562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 98564562Sgshapiro alias dereference option; "-Z size" limits the number of 98664562Sgshapiro matches to return. 98764562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 98864562Sgshapiro LDAP maps. The value should only contain LDAP specific 98964562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 99064562Sgshapiro settings will be used for all LDAP maps unless they are 99164562Sgshapiro specified in the individual map specification ('K' 99264562Sgshapiro command). This option should be set before any LDAP maps 99364562Sgshapiro are defined. 99464562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 99564562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 99664562Sgshapiro Tech. 99764562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 99864562Sgshapiro particular, class entries get much smaller, which can be 99964562Sgshapiro important if you have large classes. 100064562Sgshapiro On network-related temporary failures, record the hostname which 100164562Sgshapiro gave error in the queued status message. Requested by 100264562Sgshapiro Ulrich Windl of the Universitat Regensburg. 100364562Sgshapiro Add new F=% mailer flag to allow for a store and forward 100464562Sgshapiro configuration. Mailers which have this flag will not attempt 100571345Sgshapiro delivery on initial receipt of a message or on queue runs 100664562Sgshapiro unless the queued message is selected using one of the 100764562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 100864562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 100964562Sgshapiro New option ControlSocketName which, when set, creates a daemon 101064562Sgshapiro control socket. This socket allows an external program to 101164562Sgshapiro control and query status from the running sendmail daemon 101264562Sgshapiro via a named socket, similar to the ctlinnd interface to the 101364562Sgshapiro INN news server. Access to this interface is controlled by 101464562Sgshapiro the UNIX file permissions on the named socket on most UNIX 101564562Sgshapiro systems (see sendmail/README for more information). An 101664562Sgshapiro example control program is provided as contrib/smcontrol.pl. 101764562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 101864562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 101964562Sgshapiro number of processors online on the system (if that can be 102064562Sgshapiro determined). For single processor machines, this change 102164562Sgshapiro has no effect. 102264562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 102364562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 102464562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 102564562Sgshapiro Motonori Nakamura of Kyoto University. 102664562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 102764562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 102864562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 102964562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 103064562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 103164562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 103264562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 103364562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 103464562Sgshapiro connection-based denial of service attacks. 103564562Sgshapiro Log basic information about authenticated connections at LogLevel 103664562Sgshapiro 10 or higher. 103764562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 103864562Sgshapiro information (from= syslog line). 103964562Sgshapiro Log the DSN code for each recipient if one is available as a new 104064562Sgshapiro equate (dsn=). 104164562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 104264562Sgshapiro New "ph" map for performing ph queries in rulesets. More 104364562Sgshapiro information is available at 104471345Sgshapiro http://www-dev.cso.uiuc.edu/sendmail/. Contributed by Mark 104571345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 104664562Sgshapiro Detect temporary lookup failures in the host map if looking up a 104764562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 104864562Sgshapiro Finnish Meteorological Institute. 104964562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 105064562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 105164562Sgshapiro When a forward file points to an alias which runs a program, run 105264562Sgshapiro the program as the default user and the default group, not 105364562Sgshapiro the forward file user. This change also assures the 105464562Sgshapiro :include: directives in aliases are also processed using 105564562Sgshapiro the default user and group. Problem noted by Sergiu 105664562Sgshapiro Popovici of DNT Romania. 105764562Sgshapiro Prevent attempts to save a dead.letter file for a user with 105864562Sgshapiro no home directory (/no/such/directory). Problem noted by 105964562Sgshapiro Michael Brown of Finnigan FT/MS. 106064562Sgshapiro Include message delay and number of tries when logging that a 106164562Sgshapiro message has been completely delivered (LogLevel of 10 or 106264562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 106364562Sgshapiro Log the sender of a message even if none of the recipients were 106464562Sgshapiro accepted. If some of the recipients were rejected, it is 106564562Sgshapiro helpful to know the sender of the message. 106664562Sgshapiro Check the root directory (/) when checking a path for safety. 106764562Sgshapiro Problem noted by John Beck of Sun Microsystems. 106864562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 106964562Sgshapiro interactive and delivering to an alias which resolves to 107064562Sgshapiro multiple files. 107164562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 107264562Sgshapiro greater (see below); the help function doesn't print the 107364562Sgshapiro version of sendmail any longer, instead it is placed in 107464562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 107564562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 107664562Sgshapiro skipped and a version line (#vers) is introduced. The 107764562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 107864562Sgshapiro version is found, a warning is logged. The '#vers' 107964562Sgshapiro directive should be placed at the top of the help file. 108064562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 108164562Sgshapiro disk succeeded. Suggested by Nick Christenson. 108264562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 108364562Sgshapiro length before the attempt. 108464562Sgshapiro If a forward points to a filename for delivery, change to the 108564562Sgshapiro user's uid before checking permissions on the file. This 108664562Sgshapiro allows delivery to files on NFS mounted directories where 108764562Sgshapiro root is remapped to nobody. Problem noted by Harald 108864562Sgshapiro Daeubler of Universitaet Ulm. 108964562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 109064562Sgshapiro host status files, not all files. 109164562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 109264562Sgshapiro in the queue file for the message and set when delivery 109364562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 109464562Sgshapiro Wonderworks Inc. 109564562Sgshapiro Add support for storing information between rulesets using the new 109664562Sgshapiro macro map class. This can be used to store information 109764562Sgshapiro between queue runs as well using $={persistentMacros}. 109864562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 109964562Sgshapiro of Hannover. 110064562Sgshapiro New map class arith to allow for computations in rules. The 110164562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 110264562Sgshapiro as key. The two operands are specified as arguments; the 110364562Sgshapiro lookup returns the result of the computation. For example, 110464562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 110564562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 110664562Sgshapiro Add new syntax for header declarations which decide whether to 110764562Sgshapiro include the header based on a macro rather than a mailer 110864562Sgshapiro flag: 110964562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 111064562Sgshapiro This should be used along with $={persistentMacros}. 111164562Sgshapiro It can be used for adding headers to a message based on 111264562Sgshapiro the results of check_* and header check rulesets. 111364562Sgshapiro Allow new named config file rule check_eoh which is called after 111464562Sgshapiro all of the headers have been collected. The input to the 111564562Sgshapiro ruleset the number of headers and the size of all of the 111664562Sgshapiro headers in bytes separated by $|. This ruleset along with 111764562Sgshapiro the macro storage map can be used to correlate information 111864562Sgshapiro gathered between headers and to check for missing headers. 111964562Sgshapiro See cf/README or doc/op/op.ps for an example. 112064562Sgshapiro Change the default for the MeToo option to True to correspond 112164562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 112264562Sgshapiro option is deprecated and will be removed from a future 112364562Sgshapiro version. 112464562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 112564562Sgshapiro Change the sendmail binary default for SuperSafe to True. 112664562Sgshapiro Display ruleset names in debug and address test mode output 112764562Sgshapiro if referencing a named ruleset. 112864562Sgshapiro New mailer equate m= which will limit the number of messages 112964562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 113064562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 113164562Sgshapiro using it to sort. Now all the same domains are really run 113264562Sgshapiro through the queue together. If they have the same MX host, 113364562Sgshapiro then they will have a much better opportunity to use the 113464562Sgshapiro connection cache if available. This should be a reasonable 113564562Sgshapiro performance improvement. Patch from Randall Winchester of 113664562Sgshapiro the University of Maryland. 113764562Sgshapiro If a message is rejected by a header check ruleset, log who would 113864562Sgshapiro have received the message if it had not been rejected. 113964562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 114064562Sgshapiro queue immediately. No delivery attempt is made. 114164562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 114264562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 114364562Sgshapiro COMMANDS). 114464562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 114564562Sgshapiro but for outgoing connections. 114664562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 114764562Sgshapiro error messages and logging) and Modifiers, i.e. 114864562Sgshapiro a require authentication 114964562Sgshapiro b bind to interface through which mail has 115064562Sgshapiro been received 115164562Sgshapiro c perform hostname canonification 115264562Sgshapiro f require fully qualified hostname 115364562Sgshapiro h use name of interface for outgoing HELO 115464562Sgshapiro command 115564562Sgshapiro C don't perform hostname canonification 115664562Sgshapiro E disallow ETRN (see RFC 2476) 115764562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 115864562Sgshapiro h use name of interface for HELO command 115964562Sgshapiro The version number for queue files (qf) has been incremented to 4. 116064562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 116164562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 116264562Sgshapiro Institutes of Health. 116364562Sgshapiro If a mailer dies, print the status in decimal instead of octal 116464562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 116564562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 116664562Sgshapiro Move message priority from sender to recipient logging. Suggested by 116764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 116864562Sgshapiro Add support for Berkeley DB 3.X. 116964562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 117064562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 117164562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 117264562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 117364562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 117464562Sgshapiro sub-options is set on the command line. Problem noted by 117564562Sgshapiro Graeme Hewson of Oracle. 117664562Sgshapiro Randomize equal preference MX records each time delivery is 117764562Sgshapiro attempted via a new connection to a host instead of once per 117864562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 117964562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 118064562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 118164562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 118264562Sgshapiro to hosts which have dynamically assigned names. 118364562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 118464562Sgshapiro the bounce for the same reason. If the body is not 8-bit 118564562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 118664562Sgshapiro not be included in the bounce. Problem noted by Valdis 118764562Sgshapiro Kletnieks of Virginia Tech. 118864562Sgshapiro The timeout for sending a message via SMTP has been changed from 118964562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 119064562Sgshapiro simply checks for progress on sending data every 5 minutes. 119164562Sgshapiro This will detect the inability to send information quicker 119264562Sgshapiro and reduce the number of processes simply waiting to 119364562Sgshapiro timeout. 119464562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 119564562Sgshapiro interface address structure when loading the system network 119664562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 119764562Sgshapiro Nanoteq. 119864562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 119964562Sgshapiro indicates the number of interfaces to read when probing 120064562Sgshapiro for hostnames and IP addresses for class w ($=w). The 120164562Sgshapiro default value is 512. Based on idea from Reinier 120264562Sgshapiro Bezuidenhout of Nanoteq. 120364562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 120464562Sgshapiro on load average. 120564562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 120664562Sgshapiro Northern Illinois University. 120764562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 120864562Sgshapiro envelope splitting has occurred. 120964562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 121064562Sgshapiro Luke Mewburn from RMIT University. 121164562Sgshapiro Add a "/quit" command to address test mode. 121264562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 121364562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 121464562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 121564562Sgshapiro Institute. 121664562Sgshapiro The contents of a class can now be copied to another class using 121764562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 121864562Sgshapiro the items in class $={Source} into the class $={Dest}. 121964562Sgshapiro Include original envelope's error transcript in bounces created for 122064562Sgshapiro split (owner-) envelopes to see the original errors when 122164562Sgshapiro the recipients were added. Based on fix from Motonori 122264562Sgshapiro Nakamura of Kyoto University. 122364562Sgshapiro Show reason for permanent delivery errors directly after the 122464562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 122564562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 122664562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 122764562Sgshapiro If the specification for the queue run interval (-q###) has a 122864562Sgshapiro syntax error, consider the error fatal and exit. 122964562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 123064562Sgshapiro noted by Motonori Nakamura of Kyoto University. 123164562Sgshapiro On operating systems which have setlogin(2), use it to set the 123264562Sgshapiro login name to the RunAsUserName when starting as a daemon. 123364562Sgshapiro This is for delivery to programs which use getlogin(). 123464562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 123564562Sgshapiro Differentiate between "command not implemented" and "command 123664562Sgshapiro unrecognized" in the SMTP dialogue. 123764562Sgshapiro Strip returns from forward and include files. Problem noted by 123864562Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 123964562Sgshapiro Prevent a core dump when using 'sendmail -bv' on an address which 124064562Sgshapiro resolves to the $#error mailer with a temporary failure. 124164562Sgshapiro Based on fix from Neil Rickert of Northern Illinois 124264562Sgshapiro University. 124364562Sgshapiro Prevent multiple deliveries of a message with a "non-local alias" 124464562Sgshapiro pointing to a local user, if canonicalization fails 124564562Sgshapiro the message was requeued *and* delivered to the alias. 124664562Sgshapiro If an invalid ruleset is declared, the ruleset name could be 124764562Sgshapiro ignored and its rules added to S0. Instead, ignore the 124864562Sgshapiro ruleset lines as well. 124964562Sgshapiro Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient 125064562Sgshapiro success DSN fields as well as duplicate entries for a 125164562Sgshapiro single address due to S5 and UserDB processing. Problems 125264562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological 125364562Sgshapiro Institute. 125464562Sgshapiro Turn off timeouts when exiting sendmail due to an interrupt signal 125564562Sgshapiro to prevent the timeout from firing during the exit process. 125664562Sgshapiro Problem noted by Michael Shapiro of Sun Microsystems. 125764562Sgshapiro Do not append @MyHostName to non-RFC822 addresses output by the EXPN 125864562Sgshapiro command or on Final-Recipient: and X-Actual-Recipient: DSN 125964562Sgshapiro headers. Non-RFC822 addresses include deliveries to 126064562Sgshapiro programs, file, DECnet, etc. 126164562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 126264562Sgshapiro spoof their return address. Based on idea from Neil Rickert 126364562Sgshapiro of Northern Illinois University and patch from Per Hedeland 126464562Sgshapiro of Ericsson. 126564562Sgshapiro Report the proper UID in the bounce message if an :include: file is 126664562Sgshapiro owned by a uid that doesn't map to a username and the 126764562Sgshapiro :include: file contains delivery to a file or program. 126864562Sgshapiro Problem noted by John Beck of Sun Microsystems. 126964562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 127064562Sgshapiro the remote server responds to the first QUIT with a 4xx 127164562Sgshapiro response code and drops the connection. This behavior was 127264562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 127364562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 127464562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 127564562Sgshapiro file is not present, the lookup failure would be marked as 127664562Sgshapiro a permanent failure instead of a temporary failure. Fix 127764562Sgshapiro from Russell King of the ARM Linux Project. 127864562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 127964562Sgshapiro instead of spaces between arguments. Problem noted by Randy 128064562Sgshapiro Wormser.

Problem noted by Juergen Georgi of RUS University 129264562Sgshapiro of Stuttgart and Kyle Tucker of Parexel International. 129364562Sgshapiro Prevent +detail information from interfering with local delivery to 129464562Sgshapiro multiple users in the same transaction (F=m). 129564562Sgshapiro Add H_FORCE flag for the X-Authentication-Warning: header, so it 129664562Sgshapiro will be added even if one already exists. Problem noted 129764562Sgshapiro by Michal Zalewski of Marchew Industries. 129864562Sgshapiro Stop processing SMTP commands if the SMTP connection is dropped. 129964562Sgshapiro This prevents a remote system from flooding the connection 130064562Sgshapiro with commands and then disconnecting. Previously, the 130164562Sgshapiro server would process all of the buffered commands. Problem 130264562Sgshapiro noted by Michal Zalewski of Marchew Industries. 130364562Sgshapiro Properly process user-supplied headers beginning with '?'. Problem 130464562Sgshapiro noted by Michal Zalewski of Marchew Industries. 130564562Sgshapiro If multiple header checks resolve to the $#error mailer, use the 130664562Sgshapiro last permanent (5XX) failure if any exist. Otherwise, use 130764562Sgshapiro the last temporary (4XX) failure. 130864562Sgshapiro RFC 1891 requires "hexchar" in a "xtext" to be upper case. Patch 130964562Sgshapiro from Ronald F. Guilmette of Infinite Monkeys & Co. 131064562Sgshapiro Timeout.ident now defaults to 5 seconds instead of 30 seconds to 131164562Sgshapiro prevent the now common delays associated with mailing to a 131264562Sgshapiro site which drops IDENT packets. Suggested by many. 131364562Sgshapiro Persistent host status data is not reloaded disk when current data 131464562Sgshapiro is available in the in-memory cache. Problem noted by Per 131564562Sgshapiro Hedeland of Ericsson. 131664562Sgshapiro mailq displays unprintable characters in addresses as their octal 131764562Sgshapiro representation and a leading backslash. This avoids problems 131864562Sgshapiro with "unprintable" characters. Problem noted by Michal 131964562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 132064562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 132164562Sgshapiro one character past the limit. This would cause subsequent 132264562Sgshapiro hops to break the line again. The '!' is now placed in 132364562Sgshapiro the last column of the limit if the line needs to be broken. 132464562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 132564562Sgshapiro from Per Hedeland of Ericsson. 132664562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 132764562Sgshapiro resolver will fall back to TCP. However, some 132864562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 132964562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 133064562Sgshapiro don't fail on ANY queries. 133164562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 133264562Sgshapiro address, do not send an empty postmaster notification DSN 133364562Sgshapiro to the postmaster. Problem noted by Neil Rickert of 133464562Sgshapiro Northern Illinois University. 133564562Sgshapiro Allow '_' and '.' in map names when parsing a sequence map 133664562Sgshapiro specification.

Suggested by Per Hedeland of Ericsson. 156764562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 156864562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 156964562Sgshapiro Institute. 157064562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 157164562Sgshapiro i.e., to set, add, or delete flags. 157264562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 157364562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 157464562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 157564562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 157664562Sgshapiro after check_rcpt and allows for exceptions from the checks. 157764562Sgshapiro CONFIG: Map declarations have been moved into their associated 157864562Sgshapiro feature files to allow greater flexibility in use of 157964562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 158064562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 158164562Sgshapiro line string for the local mailer. Requested by Il Oh of 158264562Sgshapiro Willamette Industries, Inc. 158364562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 158464562Sgshapiro converted to <user@d> 158564562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 158664562Sgshapiro Sun's older, broken configuration files. 158764562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 158864562Sgshapiro normal configuration, allowing anti-spam checks to be 158964562Sgshapiro performed. 159064562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 159164562Sgshapiro ${client_name} can't be resolved just temporarily. 159264562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 159364562Sgshapiro Institute. 159464562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 159564562Sgshapiro be accessed by their numbers). 159664562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 159764562Sgshapiro which describes whether to disallow "!" in the local part 159864562Sgshapiro of an address. 159964562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 160064562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 160164562Sgshapiro set. If the ruleset returns a mailer, the appropriate 160264562Sgshapiro action is taken, otherwise the returned tokens are ignored. 160364562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 160464562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 160564562Sgshapiro The latter is kept around for backward compatibility. 160664562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 160764562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 160864562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 160964562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 161064562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 161164562Sgshapiro Institute. 161264562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 161364562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 161464562Sgshapiro arguments overriding the mailer program, arguments, and 161564562Sgshapiro mailer definition flags. This makes it possible to use 161664562Sgshapiro other programs such as maildrop for local delivery. 161764562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 161864562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 161964562Sgshapiro Patch from Richard A. Nelson of IBM. 162064562Sgshapiro CONFIG: Add SMTP Authentication information to Received: header 162164562Sgshapiro default value (confRECEIVED_HEADER). 162264562Sgshapiro CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a 162364562Sgshapiro local mailer. Problem noted by Per Hedeland of Ericsson. 162464562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 162564562Sgshapiro University of California at Berkeley. 162664562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of 162764562Sgshapiro Illinois at Urbana-Champaign. 162864562Sgshapiro CONTRIB: etrn.pl now recognizes bogus host names. Patch from 162964562Sgshapiro Bruce Barnett of GE's R&D Lab. 163064562Sgshapiro CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle 163164562Sgshapiro Corporation UK. 163264562Sgshapiro CONTRIB: Added qtool.pl to assist in managing the queues. 163364562Sgshapiro DEVTOOLS: Prevent user environment variables from interfering with 163464562Sgshapiro the Build scripts. Problem noted by Ezequiel H. Panepucci of 163564562Sgshapiro Yale University. 163664562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 163764562Sgshapiro be used for building. 163864562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 163964562Sgshapiro used for a fresh build. 164064562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 164164562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 164264562Sgshapiro ranlib. 164364562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 164464562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 164564562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 164664562Sgshapiro building of the man pages when defined. Suggested by Bryan 164764562Sgshapiro Costales. 164864562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 164964562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 165064562Sgshapiro installation of the sendmail helpfile and statistics file 165164562Sgshapiro respectively. Suggested by Bryan Costales. 165264562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 165364562Sgshapiro of Siemens Business Services. 165464562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 165564562Sgshapiro stdio library. The new buffered file I/O depends on the 165664562Sgshapiro Torek stdio library. This option can be either portable or 165764562Sgshapiro torek. 165864562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 165964562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 166064562Sgshapiro They should contain the C source files for the object files 166164562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 166264562Sgshapiro will be passed to the 'make depend' stage of compilation. 166364562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 166464562Sgshapiro in the sendmail distribution. Each has the form 166564562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 166664562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 166764562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 166864562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 166964562Sgshapiro building the distribution, but documentation on the changes 167064562Sgshapiro are in devtools/README. 167164562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 167264562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 167364562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 167464562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 167564562Sgshapiro new variable which identifies the root of the source 167664562Sgshapiro directories for all of the programs in the distribution. 167764562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 167864562Sgshapiro time. They can both still be overridden by setting the m4 167964562Sgshapiro macro. 168064562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 168164562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 168264562Sgshapiro build configurations, and places objects in obj.prefix.*/. 168364562Sgshapiro Complains as 'Build -f file' does for existing object 168464562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 168564562Sgshapiro Corporation. 168664562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 168764562Sgshapiro manual pages in the directory tree specified by 168864562Sgshapiro confMANROOTMAN. 168964562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 169064562Sgshapiro preformatted pages from the distribution. The new variable 169164562Sgshapiro confCOPY specifies the copying program. 169264562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 169364562Sgshapiro question. Suggested by Terry Lambert of Whistle 169464562Sgshapiro Communications. 169564562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 169664562Sgshapiro of the installed statistics and help files, respectively. 169764562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 169864562Sgshapiro operating system identity. Problem noted by Erik 169964562Sgshapiro Wachtenheim of Dartmouth College. 170064562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 170164562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 170264562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 170364562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 170464562Sgshapiro how to strip binaries. These are used by the new 170564562Sgshapiro install-strip target. 170664562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 170764562Sgshapiro the others (if it exists). 170864562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 170964562Sgshapiro then the default ones. 171064562Sgshapiro MAIL.LOCAL: Will not be installed setuid root. To use mail.local 171164562Sgshapiro as local delivery agent without LMTP mode, use 171264562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 171364562Sgshapiro to set the S flag. 171464562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 171564562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 171664562Sgshapiro Northern Illinois University. 171764562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 171864562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 171964562Sgshapiro the Finnish Meteorological Institute. 172064562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 172164562Sgshapiro MAILLOCK when compiling. Also requires linking with 172264562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 172364562Sgshapiro University. 172464562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 172564562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 172664562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 172764562Sgshapiro University. 172864562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 172964562Sgshapiro structure to the beginning of the program. This ensures that 173064562Sgshapiro the getservbyname() is done before any seteuid to a possibly 173164562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 173264562Sgshapiro on a Solaris system, this avoids syslog messages such as, 173364562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 173464562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 173564562Sgshapiro University. 173664562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 173764562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 173864562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 173964562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 174064562Sgshapiro characters (in LMTP mode), mail.local split the incoming 174164562Sgshapiro line up into 2046-character output lines (excluding the 174264562Sgshapiro newline). If an input line was 2047 characters long 174364562Sgshapiro (excluding CR-LF) and the last character was a '.', 174464562Sgshapiro mail.local saw it as the end of input, transfered it to the 174564562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 174664562Sgshapiro If the message was much longer, both sendmail and 174764562Sgshapiro mail.local would deadlock waiting for each other to read 174864562Sgshapiro what they have written. Problem noted by Peter Jeremy of 174964562Sgshapiro Alcatel Australia Limited. 175064562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 175164562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 175264562Sgshapiro Neil Rickert of Northern Illinois University. 175364562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 175464562Sgshapiro timeout to avoid starvation. 175564562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 175664562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 175764562Sgshapiro Infinite Monkeys & Co. 175864562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 175964562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 176064562Sgshapiro printed in a machine readable fashion and the stats file 176164562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 176264562Sgshapiro of Maryland. 176364562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 176464562Sgshapiro generated maps to the TrustedUser as specified in the 176564562Sgshapiro sendmail configuration file. 176664562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 176764562Sgshapiro configuration file to use for finding the TrustedUser 176864562Sgshapiro option. 176964562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 177064562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 177164562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 177264562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 177364562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 177464562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 177564562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 177664562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 177764562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 177864562Sgshapiro Corporation UK. 177964562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 178064562Sgshapiro (e.g., sendmail would not drop root privileges if the 178164562Sgshapiro option was specified on the command line). Problem noted 178264562Sgshapiro by Todd C. Miller of Courtesan Consulting. 178364562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 178464562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 178564562Sgshapiro Institute for Global Communications. 178664562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 178764562Sgshapiro alias file(s) if the -f option is not used. Patch from 178864562Sgshapiro John Beck of Sun Microsystems. 178964562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 179064562Sgshapiro configuration file to use for finding alias file(s). Patch 179164562Sgshapiro from John Beck of Sun Microsystems. 179264562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 179364562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 179464562Sgshapiro of the Institute for Global Communications. 179564562Sgshapiro SMRSH: Update README for the new Build system.

Sites 224038032Speter which need the ability to override security can use the 224138032Speter DontBlameSendmail option. See the README file for more 224238032Speter information. 224338032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 224438032Speter if maps or alias files are in world writable directories. 224538032Speter This fixes the change added to 8.8.6 to prevent links in these 224638032Speter world writable directories. 224738032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 224838032Speter it is in a world writable directory. 224938032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 225038032Speter tty it may be able to push bytes back to the senders input. 225138032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 226038032Speter reverts back to the old behavior of using uid 1 and gid 1. 226138032Speter This is a security problem for Linux which has chosen that 226238032Speter uid and gid for user bin instead of daemon. If DefaultUser 226338032Speter is set in the configuration file, that value overrides this 226438032Speter default. 226538032Speter SECURITY: Since 8.8.7, the check for non-setuid binaries 226638032Speter interfered with setting an alternate group id for the 226738032Speter RunAsUser option.

After this number is reached, sendmail 231138032Speter starts returning "452 Too many recipients" to all RCPT 231238032Speter commands. This can be used to limit the number of recipients 231338032Speter per envelope (in particular, to discourage use of the server 231438032Speter for spamming). Note: a better approach is to restrict 231538032Speter relaying entirely. 231638032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 231738032Speter to ldapx map and added timeout for ldap_open call to 231838032Speter avoid hanging sendmail in the event of hung LDAP servers. 231938032Speter Patch from Booker Bense of Stanford University. 232038032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 233938032Speter of Procter & Gamble. 234038032Speter The LDAP map -s flag was not properly parsed and the error message 234164562Sgshapiro given included the remainder of the arguments instead of 234238032Speter solely the argument in error. Problem noted by Aidan Nichol 234338032Speter of Procter & Gamble. 234438032Speter New DontBlameSendmail option. This option allows administrators to 234538032Speter bypass some of sendmail's file security checks at the expense 234638032Speter of system security.

In particular, if you 238238032Speter have lots of virtual interfaces, this option will speed up 238338032Speter startup. However, unless you make other arrangements, mail 238438032Speter sent to those addresses will be bounced. 238538032Speter Automatically create alias databases if they don't exist and 238638032Speter AutoRebuildAliases is set. 238738032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 238838032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 238938032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 239038032Speter When determining the client host name ($&{client_name} macro), do 239138032Speter a forward (A) DNS lookup on the result of the PTR lookup 239238032Speter and compare results. If they differ or if the PTR lookup 239338032Speter fails, &{client_name} will contain the IP address 239464562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 239538032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 239638032Speter (i.e, it is like -ax for the temporary failure case, in 239738032Speter contrast to the success case). 239838032Speter New syntax to do limited checking of header syntax. A config line 239938032Speter of the form: 240038032Speter HHeader: $>Ruleset 240138032Speter causes the indicated Ruleset to be invoked on the Header 240238032Speter when read. This ruleset works like the check_* rulesets -- 240338032Speter that is, it can reject mail on the basis of the contents. 240438032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 240538032Speter from hiding their connection information in Received: 240638032Speter headers. 240738032Speter When SingleThreadDelivery is active, deliveries to locked hosts 240838032Speter are skipped. This will cause the delivering process to 240938032Speter try the next MX host or queue the message if no other MX 241038032Speter hosts are available. Suggested by Alexander Litvin. 241138032Speter The [FILE] mailer type now delivers to the file specified in the 241238032Speter A= equate of the mailer definition instead of $u. It also 241338032Speter obeys all of the F= mailer flags such as the MIME 241438032Speter 7/8 bit conversion flags. This is useful for defining 241538032Speter a mailer which delivers to the same file regardless of the 241664562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 241738032Speter Do not assume the identity of a remote connection is root@localhost 241838032Speter if the remote connection closes the socket before the 241938032Speter remote identity can be queried. 242038032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 242138032Speter Some mailers, including procmail, require that the real 242238032Speter uid is left unchanged by sendmail. Problem noted by Per 242338032Speter Hedeland of Ericsson. 242438032Speter No longer is the src/obj*/Makefile selected from a large list -- it 242538032Speter is now generated using the information in BuildTools/OS/ -- 242638032Speter some of the details are determined dynamically via 242738032Speter BuildTools/bin/configure.sh. 242838032Speter The other programs in the sendmail distribution -- mail.local, 242938032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 243038032Speter the new Build method which creates an operating system 243138032Speter specific Makefile using the information in BuildTools. 243238032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 243338032Speter a failure on one message won't affect future messages to the 243438032Speter same host). This is necessary if the remote host sends 243538032Speter a 451 error if the domain of the sender does not resolve 243638032Speter as is common in anti-spam configurations. Problem noted 243738032Speter by Mitchell Blank Jr of Exec-PC. 243838032Speter New "discard" mailer for check_* rulesets and header checking 243938032Speter rulesets. If one of the above rulesets resolves to the 244038032Speter $#discard mailer, the commands will be accepted but the 244138032Speter message will be completely discarded after it is accepting. 244238032Speter This means that even if only one of the recipients 244338032Speter resolves to the $#discard mailer, none of the recipients 244438032Speter will receive the mail. Suggested by Brian Kantor. 244538032Speter All but the last cloned envelope of a split envelope were queued 244638032Speter instead of being delivered.

Problem noted by 248038032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 248138032Speter Include a magic number and version in the StatusFile for the 248238032Speter mailstats command. 248338032Speter Record the number of rejected and discarded messages in the 248438032Speter StatusFile for display by the mailstats command. Patch 248538032Speter from Randall Winchester of the University of Maryland. 248638032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 248738032Speter user portion as IDENT:username@site instead of 248838032Speter username@site to differentiate the two. Suggested by 248938032Speter Kari Hurtta of the Finnish Meteorological Institute. 249038032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 249138032Speter Ericsson. 249238032Speter Change persistent host status filename substitution so '/' is 249338032Speter replaced by ':' instead of '|' to avoid clashes. Also 249438032Speter avoid clashes with hostnames with leading dots. Fix from 249538032Speter Mitchell Blank Jr. of Exec-PC. 249638032Speter If the system lock table is full, only attempt to create a new 249738032Speter queue entry five times before giving up. Previously, it 249838032Speter was attempted indefinitely which could cause the partition 249938032Speter to run out of inodes. Problem noted by Suzie Weigand of 250038032Speter Stratus Computer, Inc. 250138032Speter In verbose mode, warn if the sendmail.cf version is less than the 250238032Speter currently supported version. 250338032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 250438032Speter from Randall S. Winchester of the University of Maryland. 250538032Speter Properly quote a full name passed via the -F command line option, 250638032Speter the Full-Name: header, or the NAME environment variable if 250738032Speter it contains characters which must be quoted. Problem noted 250838032Speter by Kari Hurtta of the Finnish Meteorological Institute. 250938032Speter Avoid possible race condition that unlocked a mail job before 251038032Speter releasing the transcript file on systems that use flock(2). 251138032Speter In some cases, this might result in a "Transcript Unavailable" 251238032Speter message in error bounces. 251338032Speter Accept SMTP replies which contain only a reply code and no 251438032Speter accompanying text. Problem noted by Fernando Fraticelli of 251538032Speter Digital Equipment Corporation. 251638032Speter Portability: 251738032Speter AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura 251838032Speter of Kyoto University. 251938032Speter AIX 4.2 requires <userpw.h> before <usersec.h>.

Patch from 254338032Speter Per Hedeland of Ericsson. 254438032Speter SunOS 5.7 includes getloadavg() function for determining 254538032Speter load average. Patch from John Beck of Sun 254638032Speter Microsystems. 254738032Speter CONFIG: Increment version number of config file. 254838032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 254938032Speter map for the various maps. The default is hash. Patch from 255038032Speter Robert Harker of Harker Systems. 255138032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 255238032Speter directory for certain programs. 255338032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 255438032Speter local mail delivery. By the default, /usr/libexec/mail.local 255538032Speter is used. This is expected to be the mail.local shipped 255638032Speter with 8.9 which is LMTP capable. The path is based on the 255738032Speter new confEBINDIR m4 variable. 255838032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 255938032Speter FEATURE(smrsh). Note that this changes the default from 256038032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 256138032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 256238032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 256338032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 256438032Speter the user to setup different .forward files for 256538032Speter user+detail addressing. 256638032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 256738032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 256838032Speter DontProbeInterfaces, and DontBlameSendmail options. 256938032Speter CONFIG: by default do not allow relaying (that is, accepting mail 257038032Speter from outside your domain and sending it to another host 257138032Speter outside your domain). 257238032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 257338032Speter any site to any site. 257438032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 257538032Speter domain as defined by the 'm' class ($=m) to relay. 257638032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 257738032Speter the MX records of the host portion of an incoming recipient. 257838032Speter CONFIG: new FEATURE(access_db) which turns on the access database 257938032Speter feature. This database give you the ability to allow 258038032Speter or refuse to accept mail from specified domains for 258138032Speter administrative reasons. By default, names that are listed 258238032Speter as "OK" in the access db are domain names, not host names. 258338032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 258438032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 258538032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 258638032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 258738032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 258838032Speter of FEATURE(access_db) and class 'R' to lookup individual 258938032Speter host names only. 259038032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 259138032Speter using % addressing is used, e.g. user%site@othersite, 259238032Speter and othersite is in class 'R', the check_rcpt ruleset 259338032Speter will strip @othersite and recheck user@site for relaying. 259438032Speter This feature changes that behavior. It should not be 259538032Speter needed for most installations. 259638032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 259738032Speter domain portion of the mail sender is a local host. This 259838032Speter should only be used if absolutely necessary as it opens 259938032Speter a window for spammers. Patch from Randall S. Winchester of 260038032Speter the University of Maryland. 260138032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 260238032Speter block incoming mail destined for certain recipient 260338032Speter usernames, hostnames, or addresses. 260438032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 260538032Speter refused if the host part of the argument to MAIL FROM: cannot 260638032Speter be located in the host name service (e.g., DNS). 260738032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 260838032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 260938032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 261038032Speter MAIL FROM: senders which do not include a domain. 261138032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 261238032Speter Realtime Blackhole List. You can specify the RBL name 261338032Speter server to contact by specifying it as an optional argument. 261438032Speter The default is rbl.maps.vix.com. For details, see 261538032Speter http://maps.vix.com/rbl/. 261638032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 261738032Speter Local_check_rcpt from check_relay, check_mail, and 261838032Speter check_rcpt. Users with local rulesets should place the 261938032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 262038032Speter returns $#OK, the message is accepted. If the ruleset 262138032Speter returns a mailer, the appropriate action is taken, else 262238032Speter the return of the ruleset is ignored. 262338032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 262438032Speter default to support file, :include:, and program deliveries. 262538032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 262638032Speter pick the proper default value. See the SECURITY note 262738032Speter above for more information. 262838032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 262938032Speter no-op. Patch from Kari Hurtta of the Finnish 263038032Speter Meteorological Institute. 263138032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 263238032Speter daemon since DEC's /bin/mail will drop the envelope 263338032Speter sender if run as mailnull. See the Digital UNIX section 263438032Speter of src/README for more information. Problem noted by 263538032Speter Kari Hurtta of the Finnish Meteorological Institute. 263638032Speter CONFIG: .cf files are now stored in the same directory with the 263738032Speter .mc files instead of in the obj directory. 263864562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 263938032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 264038032Speter setting SingleLineFromHeader, AllowBogusHELO, and 264138032Speter MustQuoteChars respectively. 264238032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This 264338032Speter SMTP-like protocol allows detailed reporting of delivery 264438032Speter status on a per-user basis.

Problem noted by Greg Nichols of Wind 277538032Speter River Systems. 277638032Speter If SingleThreadDelivery was enabled and the remote server returned a 277738032Speter protocol error on the DATA command, the connection would be 277838032Speter closed but the persistent host status file would not be 277938032Speter unlocked so other sendmail processes could not deliver to 278038032Speter that host. Problem noted by Peter Wemm of DIALix. 278138032Speter If queueing up a message due to an expensive mailer, don't increment 278238032Speter the number of delivery attempts or set the last delivery 278338032Speter attempt time so the message will be delivered on the next 278438032Speter queue run regardless of MinQueueAge. Problem noted by 278538032Speter Brian J. Coan of the Institute for Global Communications. 278638032Speter Authentication warnings of "Processed from queue _directory_" and 278738032Speter "Processed by _username_ with -C _filename_" would be logged 278838032Speter with the incorrect timestamp.

Problem noted by 279238032Speter Jon Lewis of Florida Digital Turnpike. 279338032Speter If class dbm maps are rebuilt, sendmail will now detect this and 279438032Speter reopen the map. Previously, they could give stale 279538032Speter results during a single message processing (but would 279638032Speter recover when the next message was received). Fix from 279738032Speter Joe Pruett of Q7 Enterprises. 279838032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 279938032Speter requests. Problem noted by Kari E.

Problem noted by Kari E. Hurtta of the 280438032Speter Finnish Meteorological Institute. 280538032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 280638032Speter sendmail via a UNIX pipe. This will allow rulesets using 280738032Speter $&{client_name} to process without sending the string through 280838032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 280938032Speter A combination of deferred delivery mode, a double bounce situation, 281038032Speter and the inability to save a bounce message to 281138032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 281238032Speter to postmaster but not remove the offending envelope from the 281338032Speter queue causing it to create a new bounce message each time the 281438032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 281538032Speter Associates. 281638032Speter Remove newlines from hostname information returned via DNS. There are 281738032Speter no known security implications of newlines in hostnames as 281838032Speter sendmail filters newlines in all vital areas; however, this 281938032Speter could cause confusing error messages. 282038032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 282138032Speter rejected if any of the specified addresses were bad. This 282238032Speter behavior was modified to only reject the bad addresses and not 282338032Speter the entire message.

From Nik Conwell of Boston University. 294238032Speter On some non-Posix systems, the decision of whether chown(2) permits 294338032Speter file giveaway was undefined. From Tetsu Ushijima of the 294438032Speter Tokyo Institute of Technology. 294538032Speter Fix race condition that could cause the body of a message to be 294638032Speter lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of 295038032Speter Results Computing. 295138032Speter If a qf file was found in a mail queue directory that had a problem 295238032Speter (wrong ownership, bad format, etc.) and the file name was 295338032Speter exactly MAXQFNAME bytes long, then instead of being tried 295438032Speter once, it would be tried on every queue run. Problem noted 295538032Speter by Bryan Costales of Mercury Mail. 295638032Speter If the system supports an st_gen field in the status structure, 295738032Speter include it when reporting that a file has changed after open. 295838032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 295938032Speter This out to be checked as well as reported, since it is 296038032Speter theoretically possible for an attacker to remove a file after 296138032Speter it is opened and replace it with another file that has the 296238032Speter same i-number, but some filesystems (notably AFS) return 296338032Speter garbage in this field, and hence always look like the file 296438032Speter has changed. As a practical matter this is not a security 296538032Speter problem, since the files can be neither hard nor soft links, 296638032Speter and on no filesystem (that I am aware of) is it possible to 296738032Speter have two files on the same filesystem with the same i-number 296838032Speter simultaneously. 296938032Speter Delete the root Makefile from the distribution -- it is only for 297038032Speter use internally, and does not work at customer sites. 297138032Speter Fix botch that caused the second MAIL FROM: command in a single 297238032Speter transaction to clear the entire transaction.

This makes it possible to create a root 305838032Speter owned file in an arbitrary directory by inserting the symlink 305938032Speter into a writable directory after the initial lstat(2) check 306038032Speter determined that the file did not exist. The only verified 306138032Speter example of a system having these odd semantics for O_EXCL 306238032Speter and symbolic links was HP-UX prior to version 9.07. Most 306338032Speter systems do not have the problem, since a exclusive create 306438032Speter of a file disallows symbolic links. Systems that have been 306538032Speter verified to NOT have the problem include AIX 3.x, *BSD, 306638032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 306738032Speter and Ultrix. This is a potential exposure on systems that 306838032Speter have this bug and which do not have a MAILER-DAEMON alias 306938032Speter pointing at a legitimate account, since this will cause old 307038032Speter mail to be dropped in /var/tmp/dead.letter. 307138032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 307238032Speter if maps or alias files are in world writable directories. 307338032Speter If your system has alias maps in writable directories, it 307438032Speter is potentially possible for an attacker to replace the .db 307538032Speter (or .dir and .pag) files by symbolic links pointing at 307638032Speter another database; this can be used either to expose 307738032Speter information (e.g., by pointing an alias file at /etc/spwd.db 307838032Speter and probing for accounts), or as a denial-of-service attack 307938032Speter (by trashing the password database). The fix disallows 308038032Speter symbolic links entirely when rebuilding alias files or on 308138032Speter maps that are in writable directories, and always warns on 308238032Speter writable directories; 8.9 will probably consider writable 308338032Speter directories to be fatal errors. This does not represent an 308438032Speter exposure on systems that have alias files in unwritable 308538032Speter system directories. 308638032Speter SECURITY: disallow .forward or :include: files that are links (hard 308738032Speter or soft) if the parent directory (or any directory in the 308838032Speter path) is writable by anyone other than the owner. This is 308938032Speter similar to the previous case for user files. This change 309038032Speter should not affect most systems, but is necessary to prevent 309138032Speter an attacker who can write the directory from pointing such 309238032Speter files at other files that are readable only by the owner. 309338032Speter SECURITY: Tighten safechown rules: many systems will say that they 309438032Speter have a safe (restricted to root) chown even on files that 309538032Speter are mounted from another system that allows owners to give 309638032Speter away files. The new rules are very strict, trusting file 309738032Speter ownership only in those few cases where the system has 309838032Speter been verified to be at least as paranoid as necessary. 309938032Speter However, it is possible to relax the rules to partially 310038032Speter trust the ownership if the directory path is not world or 310138032Speter group writable. This might allow someone who has a legitimate 310238032Speter :include: file (referenced directly from /etc/aliases) to 310338032Speter become another non-root user if the :include: file is in a 310438032Speter non-writable directory on an NFS-mounted filesystem where 310538032Speter the local system says that giveaway is denied but it is 310638032Speter actually permitted. I believe this to be a very small set 310738032Speter of cases. If in doubt, do not point :include: aliases at 310838032Speter NFS-mounted filesystems. 310938032Speter SECURITY: When setting a numeric group id using the RunAsUser option 311038032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 311138032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 311238032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 311338032Speter The user id was still set properly. Problem noted by Uli 311438032Speter Pralle of the Technical University of Berlin. 311538032Speter Save the initial gid set for use when checking for if the 311638032Speter PrivacyOptions=restrictmailq option is set.

Patch 312338032Speter from Theo de Raadt. 312438032Speter The "Message is too large" error didn't successfully bounce the error 312538032Speter back to the sender.

Note that this should really 315738032Speter be fixed in the zone file for the domain. Problem noted by 315838032Speter Joe Rhett of Navigist, Inc. 315938032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 316038032Speter the message as having been tried; otherwise the next queue 316138032Speter run will not realize that this is a second attempt and will 316238032Speter retry immediately. Problem noted by Bryan Costales of 316338032Speter Mercury Mail. 316438032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 316538032Speter will be run until the later setting of the clock is reached. 316638032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 316738032Speter Morgan Stanley. 316838032Speter If the load average rises above the cutoff threshold (above which 316938032Speter sendmail will not process the queue at all) during a queue 317038032Speter run, abort the queue run immediately. Problem noted by 317138032Speter Bryan Costales of Mercury Mail. 317238032Speter The variable queue processing algorithm (based on the message size, 317338032Speter number of recipients, message precedence, and job age) was 317438032Speter non-functional -- either the entire queue was processed or 317538032Speter none of the queue was processed. The updated algorithm 317638032Speter does no queue run if a single recipient zero size job will 317738032Speter not be run. 317838032Speter If there is a fatal ("panic") message that will cause sendmail to 317938032Speter die immediately, never hold the error message for future 318038032Speter printing. 318138032Speter Force ErrorMode=print in -bt mode so that all errors are printed 318238032Speter regardless of the setting of the ErrorMode option in the 318338032Speter configuration file. Patch from Gregory Neil Shapiro. 318438032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 318538032Speter routine available in one of the libraries. Use it in conf.h. 318638032Speter The -m (match only) flag now works on host class maps. 318738032Speter If class hash or btree maps are rebuilt, sendmail will now detect 318838032Speter this and reopen the map. Previously, they could give 318938032Speter erroneous results during a single message processing 319038032Speter (but would recover when the next message was received). 319138032Speter Don't delete zero length queue files when doing queue runs until the 319238032Speter files are at least ten minutes old. This avoids a potential 319338032Speter race condition: the creator creates the qf file, getting back 319438032Speter a file descriptor. The queue runner locks it and deletes it 319538032Speter because it is zero length. The creator then writes the 319638032Speter descriptor that is now for a disconnected file, and the 319738032Speter job goes away. Based on a suggestion by Bryan Costales. 319838032Speter When determining the "validated" host name ($_ macro), do a forward 319938032Speter (A) DNS lookup on the result of the PTR lookup and compare 320038032Speter results. If they differ or if the PTR lookup fails, tag the 320138032Speter address as "may be forged". 320238032Speter Log null connections (i.e., hosts that connect but do not do any 320338032Speter substantive activity on the connection before disconnecting; 320438032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 320538032Speter Always permit "writes" to /dev/null regardless of the link count. 320638032Speter This is safe because /dev/null is special cased, and no open 320738032Speter or write is ever actually attempted. Patch from Villy Kruse 320838032Speter of TwinCom. 320938032Speter If a message cannot be sent because of a 552 (exceeded storage 321038032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 321138032Speter was given, don't return the body in the bounce, since there 321238032Speter is a very good chance that the message will double-bounce. 321338032Speter Fix possible line truncation if a quoted-printable had an =00 escape 321438032Speter in the body. Problem noted by Charles Karney of the Princeton 321538032Speter Plasma Physics Laboratory. 321638032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 321738032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 321838032Speter Institute. 321938032Speter The MaxDaemonChildren option wasn't applying to queue runs as 322038032Speter documented. Note that this increases the potential denial 322138032Speter of service problems with this option: an attacker can 322238032Speter connect many times, and thereby lock out queue runs as well 322338032Speter as incoming connections. If you use this option, you should 322438032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 322538032Speter to avoid this attack. Failure to limit noted by Matthew 322638032Speter Dillon of BEST Internet Communications. 322738032Speter Always give a message in newaliases if alias files cannot be 322838032Speter opened instead of failing silently. Suggested by Gregory 322938032Speter Neil Shapiro. This change makes the code match the O'Reilly 323038032Speter book (2nd edition). 323138032Speter Some older versions of the resolver could return with h_errno == -1 323238032Speter if no name server could be reached, causing mail to bounce 323338032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 323438032Speter John Beck of SunSoft. 323538032Speter If a :include: file is owned by a user that does not have an entry 323638032Speter in the passwd file, sendmail could dereference a null pointer. 323738032Speter Problem noted by Satish Mynam of Sun Microsystems. 323838032Speter Take precautions to make sure that the SMTP protocol cannot get out 323938032Speter of sync if (for example) an alias file cannot be opened. 324038032Speter Fix a possible race condition that can cause a SIGALRM to come in 324138032Speter immediately after a SIGHUP, causing the new sendmail to die. 324238032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 324338032Speter from Villy Kruse of TwinCom. 324438032Speter Ignore improperly formatted SMTP reply codes. Previously these were 324538032Speter partially processed, which could cause confusing error 324638032Speter returns. 324738032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 324838032Speter on some architectures. 324938032Speter Portability: 325038032Speter A/UX: from Jim Jagielski of NASA/GSFC. 325138032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 325238032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 325338032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 325438032Speter defined. Problem reported by A Sun of the University 325538032Speter of Washington. 325638032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 325738032Speter the system rather than guessing at compile time. 325838032Speter Patch contributed by John Beck of Sun Microsystems. 325938032Speter Intel Paragon: from Wendy Lin of Purdue University. 326038032Speter GNU Hurd: from Miles Bader of the GNU project. 326138032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 326238032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 326338032Speter Unfortunately releasing them opens a race condition, 326438032Speter but there appears to be no fix for this. Patch from 326538032Speter Gregory Neil Shapiro. 326638032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 326738032Speter Solaris: a bug in strcasecmp caused characters with the 326838032Speter high order bit set to apparently randomly match 326938032Speter letters -- for example, $| (0233) matches "i" and "I". 327038032Speter Problem noted by John Gregson of the University of 327138032Speter Cambridge. 327238032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 327338032Speter Kari Hurtta. 327438032Speter IRIX 6.x: Create Makefiles for systems that claim to be 327538032Speter IRIX64 but are 6.2 or higher (so use the regular 327638032Speter IRIX Makefile). 327738032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 327838032Speter Problem noted by Eric Hagberg of Morgan Stanley. 327938032Speter CONFIG: Some canonification was still done for UUCP-like addresses 328038032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 328138032Speter Brian Candler. 328238032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 328338032Speter local names as local. Problem noted by Jeff Polk of BSDI; 328438032Speter fix provided by Gregory Neil Shapiro. 328538032Speter CONFIG: The "local:user" syntax entries in mailertables and other 328638032Speter "mailer:user" syntax locations returned an incorrect value 328738032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 328838032Speter CONFIG: Retain "+detail" information when forwarding mail to a 328938032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 329038032Speter Guenther of Gustavus Adolphus College. 329138032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 329238032Speter rules are the same as for aliasing. Based on a patch from 329338032Speter Gregory Neil Shapiro. 329438032Speter CONFIG: Break up parsing rules into several pieces; this should 329538032Speter have no functional change in this release, but makes it 329638032Speter possible to have better anti-spam rulesets in the future. 329738032Speter CONFIG: Disallow double dots in host names to avoid having the 329838032Speter HostStatusDirectory store status under the wrong name. 329938032Speter In some cases this can be used as a denial-of-service attack. 330038032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 330138032Speter Gregory Neil Shapiro. 330238032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 330338032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 330438032Speter don't include From_, and convert to 8-bit). Suggestions 330538032Speter from Kimmo Suominen and Roderick Schertler. 330664562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 330738032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 330838032Speter was specified, even when it wasn't. 330938032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 331038032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 331138032Speter "slip in" a symbolic link between the lstat(2) call and the 331238032Speter exclusive open. This is only a problem on System V derived 331338032Speter systems that allow an exclusive create on files that are 331438032Speter symbolic links pointing nowhere. 331538032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 331638032Speter not reset back to root, which on some systems would cause 331738032Speter later mailboxes to fail. Also, any partial message would 331838032Speter not be truncated, which could result in repeated deliveries. 331938032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 332038032Speter developers). 332138032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 332238032Speter change to the sendmail map code was made in 8.8.3. Problem 332338032Speter noted by Gregory Neil Shapiro. 332438032Speter MAKEMAP: Give warnings on file problems such as map files that are 332538032Speter symbolic links; although makemap is not setuid root, it is 332638032Speter often run as root and hence has the potential for the same 332738032Speter sorts of problems as alias rebuilds. 332838032Speter MAKEMAP: Change compilation so that it will link properly on 332938032Speter NEXTSTEP. 333038032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 333138032Speter Accept an optional list of arguments following the server 333238032Speter name for the ETRN arguments to use (instead of $=w). Other 333338032Speter miscellaneous bug fixes. From Christian von Roques via 333438032Speter John Beck of Sun Microsystems. 333538032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 333638032Speter Perl script converts GECOS information in the /etc/passwd 333738032Speter file into aliases, allowing for faster access to full name 333838032Speter lookups; it is also clever about adding aliases (to root) 333938032Speter for system accounts. 334038032Speter NEW FILES: 334138032Speter src/safefile.c 334238032Speter cf/ostype/gnuhurd.m4 334338032Speter cf/ostype/irix6.m4 334438032Speter contrib/passwd-to-alias.pl 334538032Speter src/Makefiles/Makefile.IRIX64.6.1 334638032Speter src/Makefiles/Makefile.IRIX64.6.x 334738032Speter RENAMED FILES: 334838032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 334938032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 335038032Speter 335164562Sgshapiro8.8.5/8.8.5 1997/01/21 335238032Speter SECURITY: Clear out group list during startup. Without this, sendmail 335338032Speter will continue to run with the group permissions of the caller, 335438032Speter even if RunAsUser is specified. 335538032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 335638032Speter to any known attack, but it's best to be conservative. 335738032Speter Suggested by Peter Wemm of DIALix. 335838032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 335938032Speter security implications. Patch from Alex Garthwaite of the 336038032Speter University of Pennsylvania. 336138032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 336238032Speter would truncate the address after "Full". Although the -f 336338032Speter syntax is incorrect (since it is in the envelope, it 336438032Speter shouldn't have comments and full names), the failure mode 336538032Speter was unnecessarily awful. 336638032Speter Fix a possible null pointer dereference when converting 8-bit data 336738032Speter to a 7-bit format. Problem noted by Jim Hutchins of 336838032Speter Sandia National Labs and David James of British Telecom. 336938032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 337038032Speter runs. Although this really shouldn't be used (F=9 is for 337138032Speter final delivery only, and using it on an SMTP mailer makes 337238032Speter it possible for a message to be converted from 8->7->8->7 337338032Speter bits several times), it shouldn't have failed with a syserr. 337438032Speter Problem noted by Eric Hagberg of Morgan Stanley. 337538032Speter _Really_ fix the multiple :maildrop code in the user database 337638032Speter module. Patch from Roy Mongiovi of Georgia Tech. 337738032Speter Let F lines in the configuration file actually read root-only 337838032Speter files if the configuration file is safe. Based on a 337938032Speter patch from Keith Reynolds of SCO. 338038032Speter ETRN followed by QUIT would hold the connection open until the queue 338138032Speter run completed. Problem noted by Truck Lewis of TDK 338238032Speter Semiconductor Corp. 338338032Speter It turns out that despite the documentation, the TCP wrappers library 338438032Speter does _not_ log rejected connections. Do the logging ourselves. 338538032Speter Problem noted by Fletcher Mattox of the University of Texas 338638032Speter at Austin. 338738032Speter If sendmail finds a qf file in its queue directory that is an unknown 338838032Speter version (e.g., when backing out to an old version), the 338938032Speter error is reported on every queue run. Change it to only 339038032Speter give the error once (and rename the qf => Qf). Patch from 339138032Speter William A. Gianopoulos of Raytheon Company. 339238032Speter Start a new session when doing background delivery; currently it 339338032Speter ignored signals but didn't start a new signal, that caused 339438032Speter some problems if a background process tried to send mail 339538032Speter under certain circumstances. Problem noted by Eric Hagberg 339638032Speter of Morgan Stanley; fix from Kari Hurtta. 339738032Speter Simplify test for skipping a queue run to just check if the current 339838032Speter load average is >= the queueing load average. Previously 339938032Speter the check factored in some other parameters that caused it 340038032Speter to essentially never skip the queue run. Patch from Bryan 340138032Speter Costales. 340238032Speter If the SMTP server is running in "nullserver" mode (that is, it is 340338032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 340438032Speter (25) commands; this helps prevent a bad guy from putting 340538032Speter you into a tight loop as a denial-of-service attack. Based 340638032Speter on an e-mail conversation with Brad Knowles of AOL. 340738032Speter Slow down when too many "light weight" commands have been issued; 340838032Speter this helps prevent a class of denial-of-service attacks. 340938032Speter The current values and defaults are: 341038032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 341138032Speter MAXHELOCOMMANDS 3 HELO, EHLO 341238032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 341338032Speter MAXETRNCOMMANDS 8 ETRN 341438032Speter These will probably be configurable in a future release. 341538032Speter On systems that have uid_t typedefed to be an unsigned short, programs 341638032Speter that had the F=S flag and no U= equate would be invoked with 341738032Speter the real uid set to 65535 rather than being left unchanged. 341838032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 341938032Speter by Steve Hubert of the University of Washington, Seattle. 342038032Speter Mail that was Quoted-Printable encoded and had a soft line break on 342138032Speter the last line (i.e., an incomplete continuation) had the last 342238032Speter line dropped. Since this appears to be illegal it isn't 342338032Speter clear what to do with it, but flushing the last line seems 342438032Speter to be a better "fail soft" approach. Based on a patch from 342538032Speter Eric Hagberg. 342638032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 342738032Speter bogus HELO command still causes the "Polite people say HELO 342838032Speter first" error message. Problem pointed out by Chris Thomas 342938032Speter of UCLA; patch from John Beck of SunSoft. 343038032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 343171345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 343271345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 343371345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 343438032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 343538032Speter in a DATA transaction to be sticky; these can occur because 343638032Speter a message is too large, and smaller messages should still go 343738032Speter through. Problem noted by Matt Dillon of Best Internet 343838032Speter Communications. 343938032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 344038032Speter had been successfully delivered to the envelope sender. 344138032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 344238032Speter Gregory Neil Shapiro of WPI. 344338032Speter Give better diagnostics on long alias lines.

Problem noted by Ronan KERYELL 347138032Speter of Centre de Recherche en Informatique de l'�cole Nationale 347238032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 347338032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 347438032Speter such as LUSER_RELAY. This change permits the following 347538032Speter syntaxes: ``local:'' will send to the same user on the 347638032Speter local machine (e.g., in a mailertable entry for "host", 347738032Speter ``local:'' will cause an address addressed to user@host to 347838032Speter go to user on the local machone). ``local:user'' will send 347938032Speter to the named user on the local machine. ``local:user@host'' 348038032Speter is equivalent to ``local:user'' (the host is ignored). In 348138032Speter all cases, the original user@host is passed in $@ (i.e., the 348238032Speter detail information). Inspired by a report from Michael Fuhr. 348338032Speter CONFIG: Strip quotes from the first word of an "error:" host 348438032Speter indication. This lets you set (for example) the LUSER_RELAY 348538032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 348638032Speter of the \" so that the resulting string is properly quoted. 348738032Speter Problem noted by Gregory Neil Shapiro of WPI. 348838032Speter OP.ME: documentation was inconsistent about whether sendmail did a 348938032Speter NOOP or a RSET to probe the connection (it does a RSET). 349038032Speter Inconsistency noted by Deeran Peethamparam. 349138032Speter OP.ME: insert additional blank pages so it will print properly on 349238032Speter a duplex printer.

The solution is to disallow any 349938032Speter files that have hard links -- this will affect .forward, 350038032Speter :include:, and output files. Problem noted by Terry 350138032Speter Kyriacopoulos of Interlog Internet Services. As a 350238032Speter workaround, set UnsafeGroupWrites -- always a good idea. 350338032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 350438032Speter is, it is possible to do a denial-of-service attack on 350538032Speter MX hosts that rely on the use of the null MX list. There 350638032Speter is no danger if you have this option turned off (the default). 350738032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 350838032Speter unsafe. I know of no specific attack against this, although 350938032Speter a denial-of-service attack is probably possible, but in theory 351038032Speter you should not be able to safely tweak anything that affects 351138032Speter the permissions that are used when mail is delivered. 351238032Speter Purgestat could go into an infinite loop if one of the host status 351338032Speter directories somehow became empty. Problem noted by Roy 351438032Speter Mongiovi of Georgia Tech. 351538032Speter Processes got "lost" when counting children due to a race condition. 351638032Speter This caused "proc_list_probe: lost pid" messages to be logged. 351738032Speter Problem noted by several people. 351838032Speter On systems with System V SIGCLD child signal semantics (notably AIX 351938032Speter and HP-UX), mail transactions would print the message "451 352038032Speter SMTP-MAIL: lost child: No child processes". Problem noted 352138032Speter by several people. 352238032Speter Miscellaneous compiler warnings on picky compilers (or when setting 352338032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 352438032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 352538032Speter not be persistent between runs, since they are based on the 352638032Speter message rather than the host. Problem noted by Matt Dillon 352738032Speter of Best Internet Communications. 352838032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 352938032Speter of NCR (a.k.a., AT&T Global Information Solutions). 353038032Speter Avoid the possibility of having a child daemon run to completion 353138032Speter (including closing the SMTP socket) before the parent has 353238032Speter had a chance to close the socket; this can cause the parent 353338032Speter to hang for a long time waiting for the socket to drain. 353438032Speter Patch from Don Lewis of TDK Semiconductor. 353538032Speter If the fork() failed in a queue run, the queue runners would not be 353638032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 353738032Speter Some error conditions in ETRN could cause output without an SMTP 353838032Speter status code. Problem noted by Don Lewis. 353938032Speter Multiple :maildrop addresses in the user database didn't work properly. 354038032Speter Patch from Roy Mongiovi of Georgia Tech. 354138032Speter Add ".db" automatically onto any user database spec that does not 354238032Speter already have it; this is for consistency with makemap, the 354338032Speter K line, and the documentation. Inconsistency pointed out 354438032Speter by Roy Mongiovi. 354538032Speter Allow sendmail to be properly called in nohup mode. Patch from 354638032Speter Kyle Jones of UUNET. 354738032Speter Change ETRN to ignore but still update host status files; previously 354838032Speter it would ignore them and not save the updated status, which 354938032Speter caused stale information to be maintained. Based on a patch 355038032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 355138032Speter ETRN ignore the MinQueueAge option. 355238032Speter Patch long term host status to recover more gracefully from an empty 355338032Speter host status file condition. Patch from NAKAMURA Motonori 355438032Speter of Kyoto University. 355538032Speter Several patches to signal handling code to fix potential race 355638032Speter conditions from Don Lewis. 355738032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 355838032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 355938032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 356038032Speter compile flag; use NETINET instead. Solution based on a 356138032Speter patch from Bryan Costales. 356238032Speter PORTABILITY FIXES: 356338032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 356438032Speter /etc/security/passwd file when called as root. This 356538032Speter is very slow on some systems. To speed it up, use the 356638032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 356738032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 356838032Speter SCO 5.x: include -lprot in the Makefile.

Problem 360738032Speter noted by Eric Bishop of Virginia Tech. 360838032Speter When doing text-based host canonification (typically /etc/hosts 360938032Speter lookup), a null host name would match any /etc/hosts entry 361038032Speter with space at the end of the line. Problem noted by Steve 361138032Speter Hubert of the University of Washington, Seattle. 361238032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 361338032Speter Problem reported by Tom Smith of Digital Equipment Corp. 361438032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 361538032Speter size PACKETSZ (512) is not sufficient for some nameserver 361638032Speter answers containing very many resource records. The resolver 361738032Speter may also switch to TCP and retry if it detects UDP packet 361838032Speter overflow. Also, allow for the fact that the resolver 361938032Speter routines res_query and res_search return the size of the 362038032Speter *un*truncated answer in case the supplied answer buffer it 362138032Speter not big enough to accommodate the entire answer. Patch from 362238032Speter Eric Wassenaar. 362338032Speter Improvements to MaxDaemonChildren code. If you think you have too 362438032Speter many children, probe the ones you have to verify that they 362538032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 362638032Speter Also, do this probe before growing the vector of children 362738032Speter pids; this previously caused the vector to grow indefinitely 362838032Speter due to a race condition. Problem reported by Kyle Jones of 362938032Speter UUNET. 363038032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 363138032Speter O_EXLOCK to zero; this fools the map compilation code into 363238032Speter thinking that it can avoid race conditions by locking on open. 363338032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 363438032Speter Leif Erlingsson of Data Lege. 363538032Speter Always call res_init() on startup (if compiled in, of course) to 363638032Speter allow the sendmail.cf file to tweak resolver flags; without 363738032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 363838032Speter Andrew Sun of Merrill Lynch. 363938032Speter Improvements to host status printing code. Suggested by Steve Hubert 364038032Speter of the University of Washington, Seattle. 364138032Speter Change MinQueueAge option processing to do the check for the job age 364238032Speter when reading the queue file, rather than at the end; this 364338032Speter avoids parsing the addresses, which can do DNS lookups. 364438032Speter Problem noted by John Beck of InReference, Inc. 364538032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 364638032Speter properly escaped. Problem noted by Peter Nilsson of the 364738032Speter University of Linkoping. 364838032Speter In some cases, sendmail would retain root permissions during queue 364938032Speter runs even if RunAsUser was set. Problem noted by Mark 365038032Speter Thomas of Mark G. Thomas Consulting. 365138032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 365238032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 365338032Speter the envelope, and the receiving SMTP server speaks DSN, then 365438032Speter the DSN would be both generated locally and propagated to the 365538032Speter other end. 365638032Speter The U= mailer field didn't correctly extract the group id if the 365738032Speter user id was numeric. Problem noted by Kenneth Herron of 365838032Speter MCI Telecommunications Communications. 365938032Speter If a message exceeded the fixed maximum size on input, the body of 366038032Speter the message was included in the bounce.

If this option is null (as 373138032Speter opposed to undefined) it can cause "null signature" syserrs 373238032Speter on illegal host names. 373338032Speter If a Base64 encoded text/plain message has no trailing newline in 373438032Speter the encoded text, conversion back to 8 bits will drop the 373538032Speter final line. Problem noted by Pierre David. 373638032Speter If running with a RunAsUser, sendmail would give bogus "cannot 373738032Speter setuid" (or seteuid, or setreuid) messages on some systems. 373838032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 373938032Speter Always print error messages in -bv mode -- previously, -bv would 374038032Speter be absolutely silent on errors if the error mode was sent 374138032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 374238032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 374338032Speter term host status. This is necessary because it is common 374438032Speter to do this when you know a host has just come back up. 374538032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 374638032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 374738032Speter University of Leicester. 374838032Speter If a service (such as NIS) is specified as the last entry in the 374938032Speter service switch, but that service is not compiled in, sendmail 375038032Speter would return a temporary failure when an entry was not found 375138032Speter in the map. This caused the message to be queued instead of 375238032Speter bouncing immediately.

Pointed out by Munenari Hirayama of 378538032Speter NSC (Japan). 378638032Speter A message that didn't terminate with a newline would (sometimes) not 378738032Speter have the trailing "." added properly in the SMTP dialogue, 378838032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 378938032Speter The DaemonPortOptions suboption to bind to a particular address was 379038032Speter incorrect and nonfunctional due to a misunderstanding of the 379138032Speter semantics of binding on a passive socket.

In order to avoid 379638032Speter trashing memory, the buffer for all names has only been 379738032Speter slightly increased in size, to 12.8K from 10.2K -- this means 379838032Speter that if a single name had 100 MX records, the average size 379938032Speter of those records could not exceed 128 bytes.

Berkeley. 380338032Speter Print q_statdate and q_specificity in address structure debugging 380438032Speter printout. 380538032Speter Expand MCI structure flag bits for debugging output. 380638032Speter Support IPv6-style domain literals, which can have colons between 380738032Speter square braces. 380838032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 380938032Speter this is an attempt to track down a bug that one person seems 381038032Speter to be having (it may be a Solaris bug!). 381138032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 381238032Speter this caused the NOTIFY info to sometimes be lost. Problem 381338032Speter pointed out by Claus Assmann of the 381438032Speter Christian-Albrechts-University of Kiel. 381538032Speter The statistics gathered in the sendmail.st file were too high; in 381638032Speter some cases failures (e.g., user unknown or temporary failure) 381738032Speter would count as a delivery as far as the statistics were 381838032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 381938032Speter Systems that don't have flock() would not send split envelopes in 382038032Speter the initial run. Problem pointed out by Leonard Zubkoff of 382138032Speter Dandelion Digital. 382238032Speter Move buffer overflow checking -- these primarily involve distrusting 382338032Speter results that may come from NIS and DNS. 382438032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 382538032Speter include <paths.h> and hence had the wrong pathnames for a few 382638032Speter things like /var/tmp. Reported by Matthew Green. 382738032Speter Conditions were reversed for the Priority: header, resulting in all 382838032Speter values being interpreted as non-urgent except for non-urgent, 382938032Speter which was interpreted as normal. Patch from Bryan Costales. 383038032Speter The -o (optional) flag was being ignored on hash and btree maps 383138032Speter since 8.7.2. Fix from Bryan Costales. 383238032Speter Content-Types listed in class "q" will always be encoded as 383338032Speter Quoted-Printable (or more accurately, will never be encoded 383438032Speter as base64). The class can have primary types (e.g., "text") 383538032Speter or full types (e.g., "text/plain"). Based on a suggestion by 383638032Speter Marius Olafsson of the University of Iceland. 383738032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 383838032Speter dialogue) so it can be passed to programs in mailers. 383938032Speter Define ${bodytype} to be the body type (from the -B flag or the 384038032Speter BODY= ESMTP parameter) so it can be passed to programs in 384138032Speter mailers. 384238032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 384338032Speter flag is set in the mailer descriptor. Suggested by John 384438032Speter Myers of CMU. 384538032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 384638032Speter The command takes a host name; data for that host is 384738032Speter immediately (and asynchronously) flushed. Because this shares 384838032Speter the -qR implementation, other hosts may be attempted, but 384938032Speter there should be no security implications. Implementation 385038032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 385138032Speter Add three new command line flags to pass in DSN parameters: -V envid 385238032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 385338032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 385438032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 385538032Speter that the -N flag applies to all recipients; there is no way 385638032Speter to specify per-address notifications on the command line, 385738032Speter nor is there an equivalent for the ORCPT= per-address 385838032Speter parameter. 385938032Speter Restore LogLevel option to be safe (it can only be increased); 386038032Speter apparently I went into paranoid mode between 8.6 and 8.7 386138032Speter and made it unsafe. Pointed out by Dabe Murphy of the 386238032Speter University of Maryland. 386338032Speter New logging on log level 15: all SMTP traffic. Patches from 386438032Speter Andrew Gross of San Diego Supercomputer Center. 386538032Speter NetInfo property value searching code wasn't stopping when it found 386638032Speter a match. This was causing the wrong values to be found (and 386738032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 386838032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 386938032Speter out by Bill Wisner of Electronics for Imaging that you can't 387038032Speter use the bracket address form for the MAIL_HUB macro, since 387138032Speter that causes the brackets to remain in the envelope recipient 387238032Speter address used for delivery. The simple fix (stripping off the 387338032Speter brackets in the config file) breaks the use of IP literal 387438032Speter addresses. This flag will solve that problem. 387538032Speter Add MustQuoteChars option. This is a list of characters that must 387638032Speter be quoted if they are found in the phrase part of an address 387738032Speter (that is, the full name part). The characters @,;:\()[] are 387838032Speter always in this list and cannot be removed. The default is 387938032Speter this list plus . and ' to match RFC 822. 388038032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 388138032Speter that do not include a host name for back compatibility with 388238032Speter some stupid SMTP clients. Setting this violates RFC 1123 388338032Speter section 5.2.5. 388438032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 388538032Speter rejecting connections if it has more than this many 388638032Speter outstanding children accepting mail. Note that you may 388738032Speter see more processes than this because of outgoing mail; this 388838032Speter is for incoming connections only. 388938032Speter Add ConnectionRateThrottle option. If set to a positive value, the 389038032Speter number of incoming SMTP connections that will be permitted 389138032Speter in a single second is limited to this number. Connections are 389238032Speter not refused during this time, just deferred. The intent is to 389338032Speter flatten out demand so that load average limiting can kick in. 389438032Speter It is less radical than MaxDaemonChildren, which will stop 389538032Speter accepting connections even if all the connections are idle 389638032Speter (e.g., due to connection caching). 389738032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 389838032Speter specifies how long cached information about the state of a 389938032Speter host will be kept before they are considered stale and the 390038032Speter host is retried. If you are using persistent host status 390138032Speter (i.e., the HostStatusDirectory option is set) this will apply 390238032Speter between runs; otherwise, it applies only within a single queue 390338032Speter run and hence is useful only for hosts that have large queues 390438032Speter that take a very long time to run. 390538032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 390638032Speter into being a single line even if they had newlines in them 390738032Speter when read. This is to get around a botch in Lotus Notes. 390838032Speter Text class maps were totally broken -- if you ever retrieved the last 390938032Speter item in a table it would be truncated. Problem noted by 391038032Speter Gregory Neil Shapiro of WPI. 391138032Speter Extend the lines printed by the mailq command (== the -bp flag) when 391238032Speter -v is given to 120 characters; this allows more information 391338032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 391438032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 391538032Speter this was treated as end-of-input. Problem noted by Bryan 391638032Speter Costales. 391738032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 391838032Speter to the queue file. Fix from John Hughes of Atlantic 391938032Speter Technologies, Inc. 392038032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 392138032Speter if this happens in a queue run it can cause nasty delays. 392238032Speter Problem noted by Mark Horton of AT&T. 392338032Speter If userdb entries pointed to userdb entries, and there were multiple 392438032Speter values for a given key, the database cursor would get 392538032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 392638032Speter of Georgia Tech. Fixed by reading all the values and creating 392738032Speter a comma-separated list; thus, the -v output will be somewhat 392838032Speter different for this case. 392938032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 393038032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 393138032Speter of Stanford University. 393238032Speter When envelopes were split due to aliases with owner- aliases, and 393338032Speter there was some error on one of the lists, more than one of 393438032Speter the owners would get the message. Problem pointed out by 393538032Speter Roy Mongiovi of Georgia Tech. 393638032Speter Detect excessive recursion in macro expansions, e.g., $X defined 393738032Speter in terms of $Y which is defined in terms of $X. Problem 393838032Speter noted by Bryan Costales; patch from Eric Wassenaar. 393938032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 394038032Speter some cases get trashed causing bogus From_ lines. Fix from 394138032Speter Kyle Jones of UUNET. 394238032Speter When doing load average initialization, if the nlist call for avenrun 394338032Speter failed, the second and subsequent lookups wouldn't notice 394438032Speter that fact causing bogus load averages to be returned. Noted 394538032Speter by Casper Dik of Sun Holland. 394638032Speter Fix problem with incompatibility with some versions of inet_aton that 394738032Speter have changed the return value to unsigned, so a check for an 394838032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 394938032Speter This could cause mail to addresses such as [foo.com] to bounce 395038032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 395138032Speter Pasteur Institute. 395238032Speter DSNs were inconsistent if a failure occurred during the DATA phase 395338032Speter rather than the RCPT phase: the Action: would be correct, but 395438032Speter the detailed status information would be wrong. Problem noted 395538032Speter by Bob Snyder of General Electric Company. 395638032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 395738032Speter that this is the initial MUA->MTA submission. The flag current 395838032Speter does nothing, but in future releases (when MUAs start using 395938032Speter these flags) it will probably turn on things like DNS 396038032Speter canonification. 396138032Speter Default end-of-line string (E= specification on mailer [M] lines) 396238032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 396338032Speter mailers. 396438032Speter Change the internal definition for the *file* and *include* mailers 396538032Speter to have $u in the argument vectors so that they aren't 396638032Speter misinterpreted as SMTP mailers and thus use \r\n line 396738032Speter termination. This will affect anyone who has redefined 396838032Speter either of these in their configuration file. 396938032Speter Don't assume that IDENT servers close the connection after a query; 397038032Speter responses can be newline terminated. From Terry Kennedy of 397138032Speter St. Peter's College. 397238032Speter Avoid core dumps on erroneous configuration files that have 397338032Speter $#mailer with nothing following. From Bryan Costales. 397438032Speter Avoid null pointer dereference with high debug values in unlockqueue. 397538032Speter Fix from Randy Martin of Clemson University. 397638032Speter Fix possible buffer overrun when expanding very large macros. Fix 397738032Speter from Kyle Jones of UUNET. 397838032Speter After 25 EXPN or VRFY commands, start pausing for a second before 397938032Speter processing each one. This avoids a certain form of denial 398038032Speter of service attack. Potential attack pointed out by Bryan 398138032Speter Costales. 398238032Speter Allow new named (not numbered!) config file rules to do validity 398338032Speter checking on SMTP arguments: check_mail for MAIL commands and 398438032Speter check_rcpt for RCPT commands. These rulesets can do anything 398538032Speter they want; their result is ignored unless they resolve to the 398638032Speter $#error mailer, in which case the indicated message is printed 398738032Speter and the command is rejected. Similarly, the check_compat 398838032Speter ruleset is called before delivery with "from_addr $| to_addr" 398938032Speter (the $| is a meta-symbol used to separate the two addresses); 399038032Speter it can give a "this sender can't send to this recipient" 399138032Speter notification. Note that this patch allows $| to stand alone 399238032Speter in rulesets. 399338032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 399438032Speter that have the name, IP address, and port number (respectively) 399538032Speter of the SMTP client (that is, the entity at the other end of 399638032Speter the connection. These can be used in (e.g.) check_rcpt to 399738032Speter verify that someone isn't trying to relay mail through your 399838032Speter host inappropriately. Be sure to use the deferred evaluation 399938032Speter form, for example $&{client_name}, to avoid having these bound 400038032Speter when sendmail reads the configuration file. 400138032Speter Add new config file rule check_relay to check the incoming connection 400238032Speter information. Like check_compat, it is passed the host name 400338032Speter and host address separated by $| and can reject connections 400438032Speter on that basis. 400538032Speter Allow IDA-style recursive function calls. Code contributed by Mark 400638032Speter Lovell and Paul Vixie. 400738032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 400838032Speter a virtual UUCP address using either a domain address or the $k 400938032Speter macro. Based on code contributed by Mark Lovell and Paul 401038032Speter Vixie. 401138032Speter Add Stanford LDAP map. Requires special libraries that are not 401238032Speter included with sendmail. Contributed by Booker C. Bense 401338032Speter <bbense@networking.stanford.edu>; contact him for support. 401438032Speter See also the src/READ_ME file. 401538032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 401638032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 401738032Speter only for debugging deep bits of code where it is important to 401838032Speter distinguish between the single-character metasymbol $+ and the 401938032Speter two characters $, +. 402038032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 402138032Speter debug_dumpstate. 402238032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 402338032Speter files that are group writable are considered "unsafe" -- that 402438032Speter is, programs and files referenced from such files are not 402538032Speter valid recipients. 402638032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 402738032Speter name that was not in DNS or was a domain-literal. Problem 402838032Speter noted by Tom May. 402938032Speter Change the introduction to error messages to more clearly delineate 403038032Speter permanent from temporary failures; if both existed in a 403138032Speter single message it could be confusing. Suggested by John 403238032Speter Beck of InReference, Inc. 403338032Speter The IngoreDot (i) option didn't work for lines that were terminated 403438032Speter with CRLF. Problem noted by Ted Stockwell of Secure 403538032Speter Computing Corporation. 403638032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 403738032Speter message headers. Problem reported by Matt Dillon of Best 403838032Speter Internet Communications. 403938032Speter Check for bogus characters in the 0200-0237 range; since these are 404038032Speter used internally, very strange errors can occur if those 404138032Speter characters appear in headers. Problem noted by Anders Gertz 404238032Speter of Lysator. 404338032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 404438032Speter recipient mailer has the F=9 flag set, and only works on 404538032Speter text/plain body types. Code contributed by Marius Olafsson 404638032Speter of the University of Iceland. 404738032Speter Special case "postmaster" name so that it is always treated as lower 404838032Speter case in alias files regardless of configuration settings; 404938032Speter this prevents some potential problems where "Postmaster" or 405038032Speter "POSTMASTER" might not match "postmaster". In most cases 405138032Speter this change is a no-op. 405238032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 405338032Speter Costales. 405438032Speter The -a map flag was ignored for dequote maps. Problem noted by 405538032Speter Bryan Costales. 405638032Speter Fix core dump when a lookup of a class "prog" map returns no 405738032Speter response. Patch from Bryan Costales. 405838032Speter Log instances where sendmail is deferring or rejecting connections 405938032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 406038032Speter Include port number in process title for network daemons. Suggested 406138032Speter by Kyle Jones of UUNET. 406238032Speter Send ``double bounces'' (errors that occur when sending an error 406338032Speter message) to the address indicated in the DoubleBounceAddress 406438032Speter option (default: postmaster). Previously they were always 406538032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 406638032Speter Add new mode, -bD, that acts like -bd in all respects except that 406738032Speter it runs in foreground. This is useful for using with a 406838032Speter wrapper that "watches" system services. Suggested by Kyle 406938032Speter Jones of UUNET. 407038032Speter Fix botch in spacing around (parenthesized) comments in addresses 407138032Speter when the comment comes before the address. Patch from 407238032Speter Motonori Nakamura of Kyoto University. 407338032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 407438032Speter that are being bounced to postmaster, rather than "Returned 407538032Speter mail". This permits the person who is postmaster more 407638032Speter easily determine what messages are to their role as 407738032Speter postmaster versus bounces to mail they actually sent. Based 407838032Speter on a suggestion by Motonori Nakamura. 407938032Speter Add new value "time" for QueueSortOrder option; this causes the queue 408038032Speter to be sorted strictly by the time of submission. Note that 408143730Speter this can cause very bad behavior over slow lines (because 408238032Speter large jobs will tend to delay small jobs) and on nodes with 408338032Speter heavy traffic (because old things in the queue for hosts that 408438032Speter are down delay processing of new jobs). Also, this does not 408538032Speter guarantee that jobs will be delivered in submission order 408638032Speter unless you also set DeliveryMode=queue. In general, it should 408738032Speter probably only be used on the command line, and only in 408838032Speter conjunction with -qRhost.domain. In fact, there are very few 408938032Speter cases where it should be used at all. Based on an 409038032Speter implementation by Motonori Nakamura. 409138032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 409238032Speter the same manner as other rulesets. Previously a temporary 409338032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 409438032Speter of Stanford University. 409538032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 409638032Speter 5yz (permanent failure) code. The next MX host will still be 409738032Speter tried if the connection cannot be opened in the first place 409838032Speter or if the MAIL command returns a 4yz (temporary failure) code. 409938032Speter (It's hard to know what to do here, since neither RFC 974 nor 410038032Speter RFC 1123 specify when to proceed to the next MX host.) 410138032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 410238032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 410338032Speter This causes map lookups that get a temporary failure (e.g., 410438032Speter name server failure) to _not_ defer the delivery of the 410538032Speter message. This should only be used if your configuration file 410638032Speter is prepared to do something sensible in this case. Based on 410738032Speter an idea by Gregory Shapiro of WPI. 410838032Speter Fix problem finding network interface addresses. Patch from 410938032Speter Motonori Nakamura. 411038032Speter Don't reject qf entries that are not owned by your effective uid if 411138032Speter you are not running setuid; this makes management of certain 411238032Speter kinds of firewall setups difficult. Patch suggested by 411338032Speter Eamonn Coleman of Qualcomm. 411438032Speter Add persistent host status. This keeps the information normally 411538032Speter maintained within a single queue run in disk files that are 411638032Speter shared between sendmail instances. The HostStatusDirectory 411738032Speter is the directory in which the information is maintained. If 411838032Speter not set, persistent host status is turned off. If not a full 411938032Speter pathname, it is relative to the queue directory. A common 412038032Speter value is ".hoststat". 412138032Speter There are also two new operation modes: 412238032Speter * -bh prints the status of hosts that have had recent 412338032Speter connections. 412438032Speter * -bH purges the host statuses. No attempt is made to save 412538032Speter recent status information. 412638032Speter This feature was originally written by Paul Vixie of Vixie 412738032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 412838032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 412938032Speter with my insistence that things fit cleanly into the V8 413038032Speter framework is gratefully appreciated. 413138032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 413238032Speter operate). Avoids letting two sendmails on the local machine 413364562Sgshapiro open connections to the same remote host at the same time. 413438032Speter This reduces load on the other machine, but can cause mail to 413538032Speter be delayed (for example, if one sendmail is delivering a huge 413638032Speter message, other sendmails won't be able to send even small 413738032Speter messages). Also, it requires another file descriptor (for the 413838032Speter lock file) per connection, so you may have to reduce 413938032Speter ConnectionCacheSize to avoid running out of per-process 414038032Speter file descriptors. Based on the persistent host status code 414138032Speter contributed by Paul Vixie and Mark Lovell. 414238032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 414338032Speter SafeFileEnvironment option is set. Problem noted by Bryan 414438032Speter Costales. 414538032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 414638032Speter file. Problem noted by Bryan Costales. 414738032Speter If a job was aborted using the interrupt signal (e.g., control-C from 414838032Speter the keyboard), on some occasions an empty df file would be 414938032Speter left around; these would collect in the queue directory. 415038032Speter Problem noted by Bryan Costales. 415138032Speter Change the makesendmail script to enhance the search for Makefiles 415238032Speter based on release number. For example, on SunOS 5.5.1, it will 415338032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 415438032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 415538032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 415638032Speter Webmasters. 415738032Speter When creating maps using "newaliases", always map the keys to lower 415838032Speter case when creating the map unless the -f flag is specified on 415938032Speter the map itself. Previously this was done based on the F=u 416038032Speter flag in the local mailer, which meant you could create aliases 416138032Speter that you could never access. Problem noted by Bob Wu of DEC. 416238032Speter When a job was read from the queue, the bits causing notification on 416338032Speter failure or delay were always set. This caused those 416438032Speter notifications to be sent even if NOTIFY=NEVER had been 416538032Speter specified. Problem noted by Steve Hubert of the University 416638032Speter of Washington, Seattle. 416738032Speter Add new configurable routine validate_connection (in conf.c). This 416838032Speter lets you decide if you are willing to accept traffic from 416938032Speter this host. If it returns FALSE, all SMTP commands will return 417038032Speter "550 Access denied". -DTCPWRAPPERS will include support for 417138032Speter TCP wrappers; you will need to add -lwrap to the link line. 417238032Speter (See src/READ_ME for details.) 417338032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 417438032Speter bounces. Some people seemed to think that this could be 417538032Speter confusing (even though it is true). Suggested by Motonori 417638032Speter Nakamura. 417738032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 417838032Speter user early in processing to avoid potential security problems. 417938032Speter However, this means that all .forward and :include: files must 418038032Speter be readable by that user, and all files to be written must be 418138032Speter writable by that user and all programs will be executed by that 418238032Speter user. It is also incompatible with the SafeFileEnvironment 418338032Speter option. In other words, it may not actually add much to 418438032Speter security. However, it should be useful on firewalls and other 418538032Speter places where users don't have accounts and the aliases file is 418638032Speter well constrained. 418738032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 418838032Speter only on the first attempt to delivery to an address. It could 418938032Speter be set to be lower than Timeout.connect on the principle that 419038032Speter the mail should go through quickly to responsive hosts; less 419138032Speter responsive hosts get to wait for the next queue run. 419238032Speter Fix a problem on Solaris that occasionally causes programs 419338032Speter (such as vacation) to hang with their standard input connected 419438032Speter to a UDP port. It also created some signal handling problems. 419538032Speter The problems turned out to be an interaction between vfork(2) 419638032Speter and some of the libraries, particularly NIS/NIS+. I am 419738032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 419838032Speter Change user class map to do the same matching that actual delivery 419938032Speter will do instead of just a /etc/passwd lookup. This adds 420038032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 420138032Speter The Timeout.* options are not safe -- they can be used to create a 420238032Speter denial-of-service attack. Problem noted by Christophe 420338032Speter Wolfhugel. 420443730Speter Don't send PostmasterCopy messages in the event of a "delayed" 420538032Speter notification. Suggested by Barry Bouwsma. 420638032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 420738032Speter option is set, since this disables VERB mode. Suggested 420838032Speter by John Hawkinson of MIT. 420938032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 421038032Speter by Motonori Nakamura of Kyoto University. 421138032Speter Only queue messages on transient .forward open failures if there 421243730Speter were no successful opens. The previous behavior caused it 421338032Speter to queue even if a "fall back" .forward was found. Problem 421438032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 421538032Speter and Computer Science (DISCS), NUS, Singapore. 421638032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 421738032Speter is bouncing because of a MIME error during 8->7 bit conversion; 421838032Speter the encapsulated message will bounce again, causing a loop. 421938032Speter Problem noted by Steve Hubert of the University of Washington. 422038032Speter Create xf (transcript) files using the TempFileMode option value 422138032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 422238032Speter National University of Singapore. 422338032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 422438032Speter detect cases where DefaultUid is set to something that the 422538032Speter system can't cope with. 422638032Speter PORTABILITY FIXES: 422738032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 422838032Speter Atlas International. 422938032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 423038032Speter <bicknell@ufp.org>. 423138032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 423238032Speter work on the first recipient of a message due to a 423338032Speter bug in the getpwent family.

Based on a patch from Randall 427638032Speter Winchester of the University of Maryland. 427738032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 427838032Speter Robert La Ferla of Hot Software. 427938032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 428038032Speter (where "code" is an exit status) on domains (previously 428138032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 428238032Speter Foundation. 428338032Speter CONFIG: hooks for IPv6-style domain literals. 428438032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 428538032Speter if it is undefined the AliasFile option is never set; this 428638032Speter should be transparent for most everyone. Suggested by John 428738032Speter Myers of CMU. 428838032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 428938032Speter domain listed in $=w is masqueraded. With it, only those 429038032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 429138032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 429238032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 429338032Speter hosts under those domains as well as the domain headers 429438032Speter themselves. For example, if a configuration had 429538032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 429638032Speter foo.com would be masqueraded; with it, *.foo.com would be 429738032Speter masqueraded as well. Based on an implementation by Richard 429838032Speter (Pug) Bainter of U. Texas. 429938032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 430038032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 430138032Speter Keys are user names; values are outgoing mail addresses. Yes, 430238032Speter this does overlap with the user database, and figuring out 430338032Speter just when to use which one may be tricky. Based on code 430438032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 430538032Speter from Per Hedeland of Ericsson. 430638032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 430738032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 430838032Speter Keys are either fully qualified addresses or just the host 430938032Speter part (with the @ sign). For example, a table containing: 431038032Speter info@foo.com foo-info 431138032Speter info@bar.com bar-info 431238032Speter @baz.org jane@elsewhere.net 431338032Speter would send all mail destined for info@foo.com to foo-info 431438032Speter (which is presumably an alias), mail addressed to info@bar.com 431538032Speter to bar-info, and anything addressed to anyone at baz.org will 431638032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 431738032Speter and baz.org must all be in $=w. Based on discussions with 431838032Speter a great many people. 431938032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 432038032Speter Suggested by Richard Bainter. 432138032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 432238032Speter "fax" mailer. 432338032Speter CONFIG: allow mailertable entries to resolve to local:user; this 432438032Speter passes the original user@host in to procmail-style local 432538032Speter mailers as the "detail" information to allow them to do 432638032Speter additional clever processing. From Joe Pruett of 432738032Speter Teleport Corporation. Delivery to the original user can 432838032Speter be done by specifying "local:" (with nothing after the colon). 432938032Speter CONFIG: allow any context that takes "mailer:domain" to also take 433038032Speter "mailer:user@domain" to force mailing to the given user; 433138032Speter "local:user" can also be used to do local delivery. This 433238032Speter applies on *_RELAY and in the mailertable entries. Based 433338032Speter on a suggestion by Ribert Kiessling of Easynet. 433438032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 433538032Speter limits the possible domains; this reduces the number of DNS 433638032Speter lookups required to support this feature. For example, 433738032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 433838032Speter to domains under my.site.com. Code contributed by Anthony 433938032Speter Thyssen <anthony@cit.gu.edu.au>. 434038032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 434138032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 434238032Speter of WPI. 434338032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 434438032Speter event you have to define local mailers. Suggested by 434538032Speter Gregory Shapiro of WPI. 434638032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 434738032Speter be misinterpreted as a list:...; syntax. Based on a patch by 434838032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 434938032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 435038032Speter remotely connected. The address host!user was being 435138032Speter converted to host!user@thishost instead of host!user@uurelay. 435238032Speter Problem noted by William Gianopoulos of Raytheon Company. 435338032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 435438032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 435538032Speter "User has moved"; the former wording was confusing if the 435638032Speter new address is still on the local host. Based on a suggestion 435738032Speter by Andreas Luik. 435838032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 435938032Speter However, the class is not pre-initialized to contain root. 436038032Speter Suggested by Gregory Neil Shapiro. 436138032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 436238032Speter Wolfhugel. 436338032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 436438032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 436538032Speter well: this produces a slightly different mailbox format (no 436638032Speter Content-Length: headers), file ownerships and modes are 436738032Speter different (not owned by group mail; mode 600 instead of 660), 436838032Speter and the local mailer flags will have to be tweaked (make them 436938032Speter match bsd4.4) in order to use this mailer. Patches from Paul 437038032Speter Hammann of the Missouri Research and Education Network. 437138032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 437238032Speter was a delivery error, such as if the ownership on the file 437338032Speter was wrong or the mode changed between the initial stat and 437438032Speter the open.

They were not 446038032Speter properly repaired in 8.7.1. 446138032Speter Completely delete the Bcc: header if and only if there are other 446238032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 446338032Speter last being a historic botch, of course). If Bcc: is the 446438032Speter only recipient header in the message, its value is tossed, 446543730Speter but the header name is kept. The old behavior (always keep 446638032Speter the header name and toss the value) allowed primary recipients 446738032Speter to see that a Bcc: went to _someone_. 446838032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 446938032Speter sender to <address> using -f'' syslog messages. Suggested 447038032Speter by Kari Hurtta. 447138032Speter If a sequence or switch map lookup entry gets a tempfail but then 447238032Speter continues on to another map type, but the name is not found, 447338032Speter return a temporary failure from the sequence or switch map. 447438032Speter For example, if hosts search ``dns files'' and DNS fails 447538032Speter with a tempfail, the hosts map will go on and search files, 447638032Speter but if it fails the whole thing should be a tempfail, not 447738032Speter a permanent (host unknown) failure, even though that is the 447838032Speter failure in the hosts.files map. This error caused hard 447938032Speter bounces when it should have requeued. 448038032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 448138032Speter owned by bar mode 700 and inbox being setuid bar stopped 448238032Speter working properly due to excessive paranoia.

Pointed out by Allan Johannesen of WPI. 451438032Speter Config files that had no AliasFile definition were defaulting to 451538032Speter using /etc/aliases; this caused problems with nullclient 451638032Speter configurations.

Fix from Brian Coan of the 454838032Speter Association for Progressive Communications. 454938032Speter If MinQueueAge was set and a message was considered but not run 455038032Speter during a queue run and the Timeout.queuereturn interval was 455138032Speter reached, a "timed out" error message would be returned that 455238032Speter didn't include the failed address (and claimed to be a warning 455338032Speter even though it was fatal). The fix is to not return such 455438032Speter messages until they are actually tried, i.e., in the next 455538032Speter MinQueueAge interval.

From Tom Moore of AT&T GIS. 461238032Speter Shorten parameters passed to syslog() in some contexts to avoid a 461338032Speter bug in many vendors' implementations of that routine. Although 461438032Speter this isn't really a bug in sendmail per se, and my solution 461538032Speter has to assume that syslog() has at least a 1K buffer size 461638032Speter internally (I know some vendors have shortened this 461738032Speter dramatically -- they're on their own), sendmail is a popular 461838032Speter target. Also, limit the size of %s arguments in sprintf. 461938032Speter These both have possible security implications. Solutions 462038032Speter suggested by Casper Dik of Sun's Network Security Group 462138032Speter (Holland), Mark Seiden, and others. 462238032Speter Fix a problem that might cause a non-standard -B (body type) 462338032Speter parameter to be passed to the next server with undefined 462438032Speter results.

Robert 463238032Speter Elz. 463338032Speter Avoid some possible null pointer dereferences. Fixes from Randy 463438032Speter Martin <WOLF@CLEMSON.EDU> 463538032Speter When sendmail starts up on systems that have no fully qualified 463638032Speter domain name (FQDN) anywhere in the first matching host map 463738032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 463838032Speter sendmail would sleep to try to find a FQDN, which it really 463938032Speter really needs. This has been changed to fall through to the 464038032Speter next map type if it can't find a FQDN -- i.e., if the hosts 464138032Speter file doesn't have a FQDN, it will try dns even though the 464238032Speter short name was found in /etc/hosts. This is probably a crock, 464338032Speter but many people have hosts files without FQDNs. Remember: 464438032Speter domain names are your friends. 464538032Speter Log a high-priority message if you can't find your FQDN during startup. 464638032Speter Suggested by Simon Barnes of Schlumberger Limited. 464738032Speter When using Hesiod, initialize it early to improve error reporting. 464838032Speter Patch from Don Lewis of Silicon Systems, Inc. 464938032Speter Apparently at least some versions of Linux have a 90 !minute!

Problem noted by Thomas Dwyer III 477738032Speter of Michigan Technological University. 477838032Speter Relax chownsafe rules slightly -- old version said that if you 477938032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 478038032Speter if fpathconf returned EINVAL or ENOSYS), assume that 478138032Speter chown is not safe. The new version falls back to whether 478238032Speter you are on a BSD system or not. This is important for 478338032Speter SunOS, which apparently always returns one of those 478438032Speter error codes. This impacts whether you can mail to files 478538032Speter or not. 478638032Speter Syntax errors such as unbalanced parentheses in the configuration 478738032Speter file could be omitted if you had "Oem" prior to the 478838032Speter syntax error in the config file. Change to always print 478938032Speter the error message. It was especially weird because it 479038032Speter would cause a "warning" message to be sent to the Postmaster 479138032Speter for every message sent (but with no transcript). Problem 479238032Speter noted by Gregory Paris of Motorola. 479338032Speter Rewrite collect and putbody to handle full 8-bit data, including 479438032Speter zero bytes. These changes are internally extensive, but 479538032Speter should have minimal impact on external function. 479638032Speter Allow full words for option names -- if the option letter is 479738032Speter (apparently) a space, then take the word following -- e.g., 479838032Speter O MatchGECOS=TRUE 479938032Speter The full list of old and new names is as follows: 480038032Speter 7 SevenBitInput 480138032Speter 8 EightBitMode 480238032Speter A AliasFile 480338032Speter a AliasWait 480438032Speter B BlankSub 480538032Speter b MinFreeBlocks/MaxMessageSize 480638032Speter C CheckpointInterval 480738032Speter c HoldExpensive 480838032Speter D AutoRebuildAliases 480938032Speter d DeliveryMode 481038032Speter E ErrorHeader 481138032Speter e ErrorMode 481238032Speter f SaveFromLine 481338032Speter F TempFileMode 481438032Speter G MatchGECOS 481538032Speter H HelpFile 481638032Speter h MaxHopCount 481738032Speter i IgnoreDots 481838032Speter I ResolverOptions 481938032Speter J ForwardPath 482038032Speter j SendMimeErrors 482138032Speter k ConnectionCacheSize 482238032Speter K ConnectionCacheTimeout 482338032Speter L LogLevel 482438032Speter l UseErrorsTo 482538032Speter m MeToo 482638032Speter n CheckAliases 482738032Speter O DaemonPortOptions 482838032Speter o OldStyleHeaders 482938032Speter P PostmasterCopy 483038032Speter p PrivacyOptions 483138032Speter Q QueueDirectory 483238032Speter q QueueFactor 483338032Speter R DontPruneRoutes 483438032Speter r, T Timeout 483538032Speter S StatusFile 483638032Speter s SuperSafe 483738032Speter t TimeZoneSpec 483838032Speter u DefaultUser 483938032Speter U UserDatabaseSpec 484043730Speter V FallbackMXHost 484138032Speter v Verbose 484238032Speter w TryNullMXList 484338032Speter x QueueLA 484438032Speter X RefuseLA 484538032Speter Y ForkEachJob 484638032Speter y RecipientFactor 484738032Speter z ClassFactor 484838032Speter Z RetryFactor 484938032Speter The old macros that passed information into sendmail have 485038032Speter been changed to options; those correspondences are: 485138032Speter $e SmtpGreetingMessage 485238032Speter $l UnixFromLine 485338032Speter $o OperatorChars 485438032Speter $q (deleted -- not necessary) 485538032Speter To avoid possible problems with an older sendmail, 485638032Speter configuration level 6 is accepted by this version of 485738032Speter sendmail; any config file using the new names should 485838032Speter specify "V6" in the configuration. 485938032Speter Change address parsing to properly note that a phrase before a 486038032Speter colon and a trailing semicolon are essentially the same 486138032Speter as text outside of angle brackets (i.e., sendmail should 486238032Speter treat them as comments). This is to handle the 486338032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 486438032Speter assume that ``group name:'' is a comment on the first 486538032Speter address and the ``;'' is a comment on the last address). 486638032Speter This requires config file support to get right. It does 486738032Speter understand that :: is NOT this syntax, and can be turned 486838032Speter off completely by setting the ColonOkInAddresses option. 486938032Speter Level 6 config files added with new mailer flags: 487038032Speter A Addresses are aliasable. 487138032Speter i Do udb rewriting on envelope as well as header 487238032Speter sender lines. Applies to the from address mailer 487338032Speter flags rather than the recipient mailer flags. 487438032Speter j Do udb rewriting on header recipient addresses. 487538032Speter Applies to the sender mailer flags rather than the 487638032Speter recipient mailer flags. 487738032Speter k Disable check for loops when doing HELO command. 487838032Speter o Always run as the mail recipient, even on local 487938032Speter delivery. 488038032Speter w Check for an /etc/passwd entry for this user. 488138032Speter 5 Pass addresses through ruleset 5. 488238032Speter : Check for :include: on this address. 488338032Speter | Check for |program on this address. 488438032Speter / Check for /file on this address. 488538032Speter @ Look up sender header addresses in the user 488638032Speter database. Applies to the mailer flags for the 488738032Speter mailer corresponding to the envelope sender 488838032Speter address, rather than to recipient mailer flags. 488938032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 489038032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 489138032Speter mailers, and the ColonOkInAddresses option. 489238032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 489338032Speter John Beck of Hewlett-Packard, who generously contributed 489438032Speter their implementation to me, which I then didn't use (see 489538032Speter mime.c for an explanation of why). This adds the 489638032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 489738032Speter to control handling of 8-bit data. These have to cope with 489838032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 489938032Speter 8-bit data that is entered without declaring it as 8-bit 490038032Speter MIME -- technically this is illegal according to the 490138032Speter specs) and labelled 8-bit data (that is, it was declared 490238032Speter as 8BITMIME in the ESMTP session or by using the 490338032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 490438032Speter set then 8-bit data is sent to non-8BITMIME machines 490538032Speter instead of converting to 7 bit (essentially using 490638032Speter just-send-8 semantics). The values for EightBitMode are: 490738032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 490838032Speter any necessary conversion of 8BITMIME to 7BIT 490938032Speter (essentially, the full MIME option). 491038032Speter p pass unlabelled 8-bit input, but convert labelled 491138032Speter 8BITMIME input to 7BIT as required (default). 491238032Speter s strict adherence: reject unlabelled 8-bit input, 491338032Speter convert 8BITMIME to 7BIT as required. The F=8 491438032Speter flag is ignored. 491538032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 491638032Speter the setting of F=8. 491738032Speter Add new internal class 'n', which is the set of MIME Content-Types 491838032Speter which can not be 8 to 7 bit encoded because of other 491938032Speter considerations. Types "multipart/*" and "message/*" are 492038032Speter never directly encoded (although their components can be). 492138032Speter Add new internal class 's', which is the set of subtypes of the 492238032Speter MIME message/* content type that can be treated as though 492338032Speter they are an RFC822 message. It is predefined to have 492438032Speter "rfc822". Suggested By Kari Hurtta. 492538032Speter Add new internal class 'e'. This is the set of MIME 492638032Speter Content-Transfer-Encodings that can be converted to 492738032Speter a seven bit format (Quoted-Printable or Base64). It is 492838032Speter preinitialized to contain "7bit", "8bit", and "binary". 492938032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 493038032Speter short name) to set the default character set to use in the 493138032Speter Content-Type: header when doing encoding of an 8-bit message 493238032Speter which isn't marked as MIME into MIME format. If the C= 493338032Speter parameter is set on the Envelope From address, use that as 493438032Speter the default encoding; else use the DefaultCharSet option. 493538032Speter If neither is set, it defaults to "unknown-8bit" as 493638032Speter suggested by RFC 1428 section 3. 493738032Speter Allow ``U=user:group'' field in mailer definition to set a default 493838032Speter user and group that a mailer will be executed as. This 493938032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 494038032Speter also set, it is the uid/gid that will always be used (that 494138032Speter is, the controlling address is ignored). The values may be 494238032Speter numeric or symbolic; if only a symbolic user is given (no 494338032Speter group) that user's default group in the passwd file is used 494438032Speter as the group. Based on code donated by Chip Rosenthal of 494538032Speter Unicom. 494638032Speter Allow `u' option to also accept user:group as a value, in the same 494738032Speter fashion as the U= mailer option. 494838032Speter Add the symbolic time zone name in the Arpanet format dates (as 494938032Speter a comment). This adds a new compile-time configuration 495038032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 495138032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 495238032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 495338032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 495438032Speter timezone()), or TZ_NONE (don't include the comment). Code 495538032Speter from Chip Rosenthal. 495638032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 495738032Speter For example, 495838032Speter O Timeout.helo = 2m 495938032Speter There are also two new suboptions "queuereturn" and 496038032Speter "queuewarn"; these subsume the old T option. Thus, to 496138032Speter set them both the preferred new syntax is 496238032Speter O Timeout.queuereturn = 5d 496338032Speter O Timeout.queuewarn = 4h 496438032Speter Sort queue by host name instead of by message priority if the 496538032Speter QueueSortOrder option (no short name) is set is set to 496638032Speter ``host''. This makes better use of the connection cache, 496738032Speter but may delay more ``interactive'' messages behind large 496838032Speter backlogs under some circumstances. This is probably a 496938032Speter good option if you have high speed links or don't do lots 497038032Speter of ``batch'' messages, but less good if you are using 497138032Speter something like PPP on a 14.4 modem. Based on code 497238032Speter contributed by Roy Mongiovi of Georgia Tech (my main 497338032Speter contribution was to make it configurable). 497438032Speter Save i-number of df file in qf file to simplify rebuilding of queue 497538032Speter after disastrous disk crash. Suggested by Kyle Jones of 497638032Speter UUNET; closely based on code from KJS DECWRL code written 497738032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 497838032Speter are NOT back compatible with 8.6 -- that is, you can convert 497938032Speter from 8.6 to 8.7, but not the other direction. 498038032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 498138032Speter route-addrs in envelopes; this is because in some cases 498238032Speter they can be sent to the shell, which interprets them as 498338032Speter I/O redirection. 498438032Speter Don't include error file (option E) with return-receipts; this 498538032Speter can be confusing. 498638032Speter Don't send "Warning: cannot send" messages to owner-* or 498738032Speter *-request addresses. Suggested by Christophe Wolfhugel 498838032Speter of the Institut Pasteur, Paris. 498938032Speter Allow -O command line flag to set long form options. 499038032Speter Add "MinQueueAge" option to set the minimum time between attempts 499138032Speter to run the queue. For example, if the queue interval 499238032Speter (-q value) is five minutes, but the minimum queue age 499338032Speter is fifteen minutes, jobs won't be tried more often than 499438032Speter once every fifteen minutes. This can be used to give 499538032Speter you more responsiveness if your delivery mode is set to 499638032Speter queue-only. 499738032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 499838032Speter :include: and .forward files. 499938032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 500038032Speter key field name, the value field name, and the field 500138032Speter delimiter. The field delimiter can be a single character 500238032Speter or the sequence "\t" or "\n" for tab or newline. 500338032Speter These are for use by NIS+ and similar access methods. 500438032Speter Change maps to always strip quotes before lookups; the -q flag 500543730Speter turns off this behavior. Suggested by Motonori Nakamura. 500638032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 500738032Speter key and value field names respectively. Code donated by 500838032Speter Sun Microsystems. 500938032Speter Add "hesiod" map class. The "file name" is used as the 501038032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 501138032Speter first value found for the match. Code donated by Scott 501238032Speter Hutton of Indiana University. 501338032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 501438032Speter specify the name of the property that is searched as the 501538032Speter key and a -v flag to specify the name of the property that 501638032Speter is returned as the value (defaults to "members"). The 501738032Speter default map is "/aliases". Some code based on code 501838032Speter contributed by Robert La Ferla of Hot Software. 501938032Speter Add "text" map class. This does slow, linear searches through 502038032Speter text files. The -z flag specifies a column delimiter 502138032Speter (defaults to any sequence of white space), the -k flag 502238032Speter sets the key column number, and the -v flag sets the 502338032Speter value column number. Lines beginning with `#' are treated 502438032Speter as comments. 502538032Speter Add "program" map class to execute arbitrary programs. The search 502638032Speter key is presented as the last argument; the output is one 502738032Speter line read from the programs standard output. Exit statuses 502838032Speter are from sysexits.h. 502938032Speter Add "sequence" map class -- searches maps in sequence until it 503038032Speter finds a match. For example, the declarations: 503138032Speter Kmap1 ... 503238032Speter Kmap2 ... 503338032Speter Kmapseq sequence map1 map2 503438032Speter defines a map "mapseq" that first searches map1; if the 503538032Speter value is found it is returned immediately, otherwise 503638032Speter map2 is searched and the value returned. 503738032Speter Add "switch" map class. This is much like "sequence" except that 503838032Speter the ordering is fetched from an external file, usually 503938032Speter the system service switch. The parameter is the name of 504038032Speter the service to switch on, and the maps that it will use 504138032Speter are the name of the switch map followed by ".service_type". 504238032Speter For example, if the declaration of the map is 504338032Speter Ksample switch hosts 504438032Speter and the system service switch specifies that hosts are 504538032Speter looked up using dns and nis in that order, then this is 504638032Speter equivalent to 504738032Speter Ksample sequence sample.dns sample.nis 504838032Speter The subordinate maps (sample.*) must already be defined. 504938032Speter Add "user" map class -- looks up users using getpwnam. Takes a 505038032Speter "-v field" flag on the definition that tells what passwd 505138032Speter entry to return -- legal values are name, passwd, uid, gid, 505238032Speter gecos, dir, and shell. Generally expected to be used with 505338032Speter the -m (matchonly) flag. 505438032Speter Add "bestmx" map class -- returns the best MX value for the host 505538032Speter listed as the value. If there are several "best" MX records 505638032Speter for this host, one will be chosen at random. 505738032Speter Add "userdb" map class -- looks up entries in the user database. 505838032Speter The "file name" is actually the tag that will be used, 505938032Speter typically "mailname". If there are multiple entries 506038032Speter matching the name, the one chosen is undefined. 506138032Speter Add multiple queue timeouts (both return and warning). These are 506238032Speter set by the Precedence: or Priority: header fields to one of 506338032Speter three values. If a Priority: is set and has value "normal", 506464562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 506538032Speter used. If no priority is set, the Precedence: is consulted; 506638032Speter if negative, non-urgent timeouts are used; if greater than 506738032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 506838032Speter are used. The timeouts are set by setting the six timeouts 506938032Speter queue{warn,return}.{urgent,normal,non-urgent}. 507038032Speter Fix problem when a mail address is resolved to a $#error mailer 507138032Speter with a temporary failure indication; it works in SMTP, 507238032Speter but when delivering locally the mail is silently discarded. 507338032Speter This patch, from Kyle Jones of UUNET, bounces it instead 507438032Speter of queueing it (queueing is very hard). 507538032Speter When using /etc/hosts or NIS-style lookups, don't assume that 507638032Speter the first name in the list is the best one -- instead, 507738032Speter search for the first one with a dot. For example, if 507838032Speter an /etc/hosts entry reads 507938032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 508038032Speter this change will use the second name as the canonical 508138032Speter machine name instead of the initial, unqualified name. 508238032Speter Change dequote map to replace spaces in quoted text with a value 508338032Speter indicated by the -s flag on the dequote map definition. 508438032Speter For example, ``Mdequote dequote -s_'' will change 508538032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 508638032Speter quoted (because of the space character). Suggested by Dan 508738032Speter Oscarsson for use in X.400 addresses. 508838032Speter Implement long macro names as ${name}; long class names can 508938032Speter be similarly referenced as $={name} and $~{name}. 509038032Speter Definitions are (e.g.) ``D{name}value''. Names that have 509138032Speter a leading lower case letter or punctuation characters are 509238032Speter reserved for internal use by sendmail; i.e., config files 509338032Speter should use names that begin with a capital letter. Based 509438032Speter on code contributed by Dan Oscarsson. 509538032Speter Fix core dump if getgrgid returns a null group list (as opposed 509638032Speter to an empty group list, that is, a pointer to a list 509738032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 509838032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 509938032Speter failed, it called syserr which called newstr which called 510038032Speter xalloc.... The newstr is now avoided for "panic" messages. 510138032Speter Reported by Stuart Kemp of James Cook University. 510238032Speter Improve connection cache timeouts; previously, they were not even 510338032Speter checked if you were delivering to anything other than an 510438032Speter IPC-connected host, so a series of (say) local mail 510538032Speter deliveries could cause cached connections to be open 510638032Speter much longer than the specified timeout. 510738032Speter If an incoming message exceeds the maximum message size, stop 510838032Speter writing the incoming bytes to the queue data file, since 510938032Speter this can fill your mqueue partition -- this is a possible 511038032Speter denial-of-service attack. 511138032Speter Don't reject all numeric local user names unless HESIOD is 511238032Speter defined. It turns out that Posix allows all-numeric 511338032Speter user names. Fix from Tony Sanders of BSDI. 511438032Speter Add service switch support. If the local OS has a service 511538032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 511638032Speter on DEC systems) that will be used; otherwise, it falls back 511738032Speter to using a local mechanism based on the ServiceSwitchFile 511838032Speter option (default: /etc/service.switch). For example, if the 511938032Speter service switch lists "files" and "nis" for the aliases 512038032Speter service, that will be the default lookup order. the "files" 512138032Speter ("local" on DEC) service type expands to any alias files 512238032Speter you listed in the configuration file, even if they aren't 512338032Speter actually file lookups. 512438032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 512538032Speter variable which tells whether or not DNS should be considered 512638032Speter canonical. This is now determined based on whether or not 512738032Speter "dns" is in the service list for "hosts". 512838032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 512938032Speter Status Notifications). DSN notifications override 513038032Speter Return-Receipt-To: headers, which are bogus anyhow -- 513138032Speter support for them has been removed. 513238032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 513338032Speter definitions to define the types used in DSN returns for 513438032Speter MTA names, addresses, and diagnostics respectively. 513538032Speter Extend heuristic to force running in ESMTP mode to look for the 513638032Speter five-character string "ESMTP" anywhere in the 220 greeting 513738032Speter message (not just the second line). This is to provide 513838032Speter better compatibility with other ESMTP servers. 513938032Speter Print sequence number of job when running the queue so you can 514038032Speter easily see how much progress you have made. Suggested 514138032Speter by Peter Wemm of DIALix. 514238032Speter Map newlines to spaces in logged message-ids; some versions of 514338032Speter syslog truncate the rest of the line after newlines. 514438032Speter Suggested by Fletcher Mattox of U. Texas. 514538032Speter Move up forking for job runs so that if a message is split into 514638032Speter multiple envelopes you don't get "fork storms" -- this 514738032Speter also improves the connection cache utilization. 514838032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 514938032Speter the purposes of refusing to send error returns. Suggested 515038032Speter by Motonori Nakamura of Ritsumeikan University. 515138032Speter Relax rules on when a file can be written when referenced from 515238032Speter the aliases file: use the default uid/gid instead of the 515338032Speter real uid/gid. This allows you to create a file owned by 515438032Speter and writable only by the default uid/gid that will work 515538032Speter all the time (without having the setuid bit set). Change 515638032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 515738032Speter Microsystems. 515838032Speter Add "DialDelay" option (no short name) to provide an "extra" 515938032Speter delay for dial on demand systems. If this is non-zero 516038032Speter and a connect fails, sendmail will wait this long and 516138032Speter then try again. If it takes longer than the kernel 516238032Speter timeout interval to establish the connection, this 516338032Speter option can give the network software time to establish 516438032Speter the link. The default units are seconds. 516538032Speter Move logging of sender information to be as early as possible; 516638032Speter previously, it could be delayed a while for SMTP mail 516738032Speter sent to aliases. Suggested by Brad Knowles of the 516838032Speter Defense Information Systems Agency. 516938032Speter Call res_init() before setting RES_DEBUG; this is required by 517038032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 517138032Speter the National Computer Security Center. 517238032Speter Add xdelay= field in logs -- this is a transaction delay, telling 517338032Speter you how long it took to deliver to this address on the 517438032Speter last try. It is intended to be used for sorting mailing 517538032Speter lists to favor "quick" addresses. Provided for use by 517638032Speter the mailprio scripts (see below). 517738032Speter If a map cannot be opened, and that map is non-optional, and 517838032Speter an address requires that map for resolution, queue the 517938032Speter map instead of bouncing it. This involves creating a 518038032Speter pseudo-class of maps called "bogus-map" -- if a required 518138032Speter map cannot be opened, the class is changed to bogus-map; 518238032Speter all queries against bogus-map return "tempfail". The 518338032Speter bogus-map class is not directly accessible. A sample 518438032Speter implementation was donated by Jem Taylor of Glasgow 518538032Speter University Computing Service. 518638032Speter Fix a possible core dump when mailing to a program that talks 518738032Speter SMTP on its standard input. Fix from Keith Moore of 518838032Speter the University of Kentucky. 518938032Speter Make it possible to resolve filenames to $#local $: @ /filename; 519038032Speter previously, the "@" would cause it to not be recognized 519138032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 519238032Speter Accept a -1 signal to re-exec the daemon. This only works if 519338032Speter argv[0] is a full path to sendmail. 519438032Speter Fix bug in "addr=..." field in O option on little-endian machines 519538032Speter -- the network number wasn't being converted to network 519638032Speter byte order. Patch from Kurt Lidl of Pix Technologies 519738032Speter Corporation. 519838032Speter Pre-initialize the resolver early on; this is to avoid a bug with 519938032Speter BIND 4.9.3 that can cause the _res.retry field to get 520038032Speter reset to zero, causing all name server lookups to time 520138032Speter out. Fix from Matt Day of Artisoft. 520238032Speter Restore T line (trusted users) in config file -- but instead of 520338032Speter locking out the -f flag, they just tell whether or not 520438032Speter an X-Authentication-Warning: will be added. This really 520538032Speter just creates new entries in class 't', so "Ft/file/name" 520638032Speter can be used to read trusted user names from a file. 520738032Speter Trusted users are also allowed to execute programs even 520838032Speter if they have a shell that isn't in /etc/shells. 520938032Speter Improve NEWDB alias file rebuilding so it will create them 521038032Speter properly if they do not already exist. This had been 521138032Speter a MAYBENEXTRELEASE feature in 8.6.9. 521238032Speter Check for @:@ entry in NIS maps before starting up to avoid 521338032Speter (but not prevent, sigh) race conditions. This ought to 521438032Speter be handled properly in ypserv, but isn't. Suggested by 521538032Speter Michael Beirne of Motorola. 521638032Speter Refuse connections if there isn't enough space on the filesystem 521738032Speter holding the queue. Contributed by Robert Dana of Wolf 521838032Speter Communications. 521938032Speter Skip checking for directory permissions in the path to a file 522038032Speter when checking for file permissions iff setreuid() 522138032Speter succeeded -- it is unnecessary in that case. This avoids 522238032Speter significant performance problems when looking for .forward 522338032Speter files. Based on a suggestion by Win Bent of USC. 522438032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 522538032Speter arbitrary ruleset number assigned or "Sname = integer" 522638032Speter to assign a specific ruleset number. Reference is 522738032Speter $>name_or_number. Names can be composed of alphas, digits, 522838032Speter underscore, or hyphen (first character must be non-numeric). 522938032Speter Allow -o flag on AliasFile lines to make the alias file optional. 523038032Speter From Bryan Costales of ICSI. 523138032Speter Add NoRecipientAction option to handle the case where there is 523238032Speter no legal recipient header in the message. It can take 523338032Speter on values: 523438032Speter None Leave the message as is. The 523538032Speter message will be passed on even 523638032Speter though it is in technically 523738032Speter illegal syntax. 523838032Speter Add-To Add a To: header with any 523938032Speter recipients that it can find from 524038032Speter the envelope. This risks exposing 524138032Speter Bcc: recipients. 524238032Speter Add-Apparently-To Add an Apparently-To: header. This 524338032Speter has almost no redeeming social value, 524438032Speter and is provided only for back 524538032Speter compatibility. 524638032Speter Add-To-Undisclosed Add a header reading 524738032Speter To: undisclosed-recipients:; 524838032Speter which will have the effect of 524938032Speter making the message legal without 525038032Speter exposing Bcc: recipients. 525138032Speter Add-Bcc To add an empty Bcc: header. 525238032Speter There is a chance that mailers down 525338032Speter the line will delete this header, 525438032Speter which could cause exposure of Bcc: 525538032Speter recipients. 525638032Speter The default is NoRecipientAction=None. 525738032Speter Truncate (rather than delete) Bcc: lines in the header. This 525838032Speter should prevent later sendmails (at least, those that don't 525938032Speter themselves delete Bcc:) from considering this message to 526038032Speter be non-conforming -- although it does imply that non-blind 526138032Speter recipients can see that a Bcc: was sent, albeit not to whom. 526238032Speter Add SafeFileEnvironment option. If declared, files named as delivery 526338032Speter targets must be regular files in addition to the regular 526438032Speter checks. Also, if the option is non-null then it is used as 526538032Speter the name of a directory that is used as a chroot(2) 526638032Speter environment for the delivery; the file names listed in an 526738032Speter alias or forward should include the name of this root. 526838032Speter For example, if you run with 526938032Speter O SafeFileEnvironment=/arch 527038032Speter then aliases should reference "/arch/rest/of/path". If a 527138032Speter value is given, sendmail also won't try to save to 527238032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 527338032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 527438032Speter Support -A flag for alias files; this will comma concatenate like 527538032Speter entries. For example, given the aliases: 527638032Speter list: member1 527738032Speter list: member2 527838032Speter and an alias file declared as: 527938032Speter OAhash:-A /etc/aliases 528038032Speter the final alias inserted will be "list: member1,member2"; 528138032Speter without -A you will get an error on the second and subsequent 528238032Speter alias for "list". Contributed by Bryan Costales of ICSI. 528338032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 528438032Speter Fix a problem that could cause very long addresses to core dump in 528538032Speter some special circumstances. Problem pointed out by Allan 528638032Speter Johannesen. 528738032Speter (Internal change.) Change interface to expand() (macro expansion) 528838032Speter to be simpler and more consistent. 528938032Speter Delete check for funny qf file names. This didn't really give 529038032Speter any extra security and caused some people some problems. 529138032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 529238032Speter at compile time.) Suggested by Kyle Jones of UUNET. 529338032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 529438032Speter merge with DSN code; this is simpler and more consistent. 529538032Speter This may affect some people who have written their own 529638032Speter checkcompat() routine. 529738032Speter (Internal change.) Eliminate `D' line in qf file. The df file 529838032Speter is now assumed to be the same name as the qf file (with 529938032Speter the `q' changed to a `d', of course). 530038032Speter Avoid forking for delivery if all recipient mailers are marked as 530138032Speter "expensive" -- this can be a major cost on some systems. 530238032Speter Essentially, this forces sendmail into "queue only" mode 530338032Speter if all it is going to do is queue anyway. 530438032Speter Avoid sending a null message in some rather unusual circumstances 530538032Speter (specifically, the RCPT command returns a temporary 530638032Speter failure but the connection is lost before the DATA 530738032Speter command). Fix from Scott Hammond of Secure Computing 530838032Speter Corporation. 530938032Speter Change makesendmail to use a somewhat more rational naming scheme: 531038032Speter Makefiles and obj directories are named $os.$rel.$arch, 531138032Speter where $os is the operating system (e.g., SunOS), $rel is 531238032Speter the release number (e.g., 5.3), and $arch is the machine 531338032Speter architecture (e.g., sun4). Any of these can be omitted, 531438032Speter and anything after the first dot in a release number can 531538032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 531638032Speter version used $os.$arch.$rel and was rather less general. 531738032Speter Change makesendmail to do a "make depend" in the target directory 531838032Speter when it is being created. This involves adding an empty 531938032Speter "depend:" entry in most Makefiles. 532038032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 532138032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 532238032Speter of the Finnish Meteorological Institute. 532338032Speter Fix problem that could cause multiple responses to DATA command 532438032Speter on header syntax errors (e.g., lines beginning with colons). 532538032Speter Problem noted by Jens Thomassen of the University of Oslo. 532638032Speter Don't let null bytes in headers cause truncation of the rest of 532738032Speter the header. 532838032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 532938032Speter Increase timeouts on message data puts to allow time for receivers 533038032Speter to canonify addresses in headers on the fly. This is still 533138032Speter a rather ugly heuristic. From Motonori Nakamura. 533238032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 533338032Speter records are not used when canonifying names, and when MX 533438032Speter lookups are done for addressing they must be fully 533538032Speter qualified. This is useful if you have a wildcard MX record, 533638032Speter although it may cause other problems. In general, don't use 533738032Speter wildcard MX records. Patch from Motonori Nakamura. 533838032Speter Eliminate default two-line SMTP greeting message. Instead of 533938032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 534038032Speter is added between the first and second word of the first 534138032Speter line of the greeting message (i.e., immediately after the 534238032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 534338032Speter compile flag. Old sendmails won't see the ESMTP, but that's 534438032Speter acceptable because SIZE was the only useful extension that 534538032Speter old sendmails understand. 534638032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 534738032Speter invoked state dumps. From Masaharu Onishi. 534838032Speter Allow on-line comments in .forward and :include: files; they are 534938032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 535038032Speter is a space or a tab. This is intended for native 535138032Speter representation of non-ASCII sets such as Japanese, where 535238032Speter existing encodings would be unreadable or would lose 535338032Speter data -- for example, 535438032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 535538032Speter (romanized/less information) 535638032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 535738032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 535838032Speter (with MIME encoding, not human readable) 535938032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 536038032Speter (native encoding with ISO-2022-JP) 536138032Speter The last form is human readable in the Japanese environment. 536238032Speter Based on a fix from (surprise!) Motonori Nakamura. 536338032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 536438032Speter messages to that host; these are most frequently associated 536538032Speter with addresses rather than the host, with the exception of 536638032Speter 421 (service shutting down). The effect was to cause queues 536738032Speter to sometimes take an excessive time to flush. Reported by 536838032Speter Robert Sargent of Southern Geographics Technologies and 536938032Speter Eric Prestemon of American University. 537038032Speter Add Nice=N mailer option to set the niceness at which a mailer will 537138032Speter run. This is actually a relative niceness (that is, an 537238032Speter increment on the background value). 537338032Speter Log queue runs that are skipped due to high loads. They are logged 537438032Speter at LOG_INFO priority iff the log level is > 8. Contributed 537538032Speter by Bruce Nagel of Data General. 537638032Speter Allow the error mailer to accept a DSN-style error status code 537738032Speter instead of an sysexits status code in the host part. 537838032Speter Anything with a dot will be interpreted as a DSN-style code. 537938032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 538038032Speter to encode characters that might be munged by an EBCDIC system 538138032Speter in addition to the set required by RFC 1521. The additional 538238032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 538338032Speter (Think of "IBM 360" as the mnemonic for this flag.) 538438032Speter Change check for mailing to files to look for a pathname of [FILE] 538538032Speter rather than looking for the mailer named *file*. The mapping 538638032Speter of leading slashes still goes to the *file* mailer. This 538738032Speter allows you to implement the *file* mailer as a separate 538838032Speter program, for example, to insert a Content-Length: header 538938032Speter or do special security policy. However, note that the usual 539038032Speter initial checking for the file permissions is still done, and 539138032Speter the program in question needs to be very careful about how 539238032Speter it does the file write to avoid security problems. 539338032Speter Be able to read ~root/.forward even if the path isn't accessible to 539438032Speter regular users. This is disrecommended because sendmail 539538032Speter sometimes does not run as root (e.g., when an unsafe option 539638032Speter is specified on the command line), but should otherwise be 539738032Speter safe because .forward files must be owned by the user for 539838032Speter whom mail is being forwarded, and cannot be a symbolic link. 539938032Speter Suggested by Forrest Aldrich of Wang Laboratories. 540038032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 540138032Speter file. This is used for canonifying hostnames when the 540238032Speter service type is "files". 540338032Speter Implement programs on F (read class from file) line. The syntax is 540438032Speter Fc|/path/to/program to read the output from the program 540538032Speter into class "c". 540638032Speter Probe the network interfaces to find alternate names for this 540738032Speter host. Requires the SIOCGIFCONF ioctl call. Code 540838032Speter contributed by SunSoft. 540938032Speter Add "E" configuration line to set or propagate environment 541038032Speter variables into children. "E<envar>" will propagate 541138032Speter the named variable from the environment when sendmail 541238032Speter was invoked into any children it calls; "E<envar>=<value>" 541338032Speter sets the named variable to the indicated value. Any 541438032Speter variables not explicitly named will not be in the child 541538032Speter environment. However, sendmail still forces an 541638032Speter "AGENT=sendmail" environment variable, in part to enforce 541738032Speter at least one environment variable, since many programs and 541838032Speter libraries die horribly if this is not guaranteed. 541938032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 542038032Speter alias databases -- new algorithm looks for the substring 542138032Speter "/yp/" in the file name. This is more portable and involves 542238032Speter less overhead. Suggested by Motonori Nakamura. 542338032Speter Dynamically allocate the queue work list so that you don't lose 542438032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 542538032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 542638032Speter should not need to be changed) and the MaxQueueRunSize option, 542738032Speter which is the absolute maximum number of jobs that will ever 542838032Speter be handled in a single queue run. Based on code contributed 542938032Speter by Brian Coan of the Institute for Global Communications. 543038032Speter Log message when a message is dropped because it exceeds the maximum 543138032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 543238032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 543338032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 543438032Speter of Mark G. Thomas Consulting. 543538032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 543638032Speter OS-dependent defines). The old semantic of -d0.1 to not 543738032Speter run the daemon in background has been moved to -d99.100, 543838032Speter and the old 52.5 flag (to avoid disconnect() from closing 543938032Speter all output files) has been moved to 52.100. This makes 544038032Speter things more consistent (flags below .100 don't change 544138032Speter semantics) and separates out the backgrounding so that 544238032Speter it doesn't happen automatically on other unrelated debugging 544338032Speter flags. 544438032Speter If -t is used but no addresses are found in the header, give an 544538032Speter error message rather than just doing nothing. Fix from 544638032Speter Motonori Nakamura. 544738032Speter On systems (like SunOS) where the effective gid is not necessarily 544838032Speter included in the group list returned by getgroups(), the 544938032Speter `restrictmailq' option could sometimes cause an authorized 545038032Speter user to not be able to use `mailq'. Fix from Charles Hannum 545138032Speter of MIT. 545238032Speter Allow symbolic service names for [IPC] mailers. Suggested by 545338032Speter Gerry Magennis of Logica International. 545438032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 545538032Speter when running DNS. For example, if the name FTP.Foo.ORG is 545638032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 545738032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 545838032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 545938032Speter This is technically illegal under RFC 822 and 1123, but the 546038032Speter IETF is moving toward legalizing it. Note that turning on 546138032Speter this option is not sufficient to guarantee that a downstream 546238032Speter neighbor won't rewrite the address for you. 546338032Speter Add "-m" flag to makesendmail script -- this tells you what object 546438032Speter directory and Makefile it will use, but doesn't actually do 546538032Speter the make. 546638032Speter Do some additional checking on the contents of the qf file to try 546738032Speter to detect attacks against the qf file. In particular, 546838032Speter abort on any line beginning "From ", and add an "end of 546938032Speter file" line -- any data after that line is prohibited. 547038032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 547138032Speter choices. This can be overridden in the Makefile by using 547238032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 547338032Speter (to the extent that we know it) or by defining 547438032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 547538032Speter sendmail 8 to have more consistent installation instructions. 547638032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 547738032Speter of Sun Microsystems. 547838032Speter Improved symbol table hash function from Eric Wassenaar. This one 547938032Speter is at least 50% faster. 548038032Speter Fix problem that didn't notice that timeout on file open was a 548138032Speter transient error. Fix from Larry Parmelee of Cornell 548238032Speter University. 548338032Speter Allow comments (lines beginning with a `#') in files read for 548438032Speter classes. Suggested by Motonori Nakamura. 548538032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 548638032Speter of dropping out entirely. This makes testing some of the 548738032Speter name server lookups easier to deal with when there are 548838032Speter hung servers. From Motonori Nakamura. 548938032Speter Add new ${opMode} macro that is set to the current operation mode 549038032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 549138032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 549238032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 549338032Speter Kind of like queue-only mode (Odq) except it tries to avoid 549438032Speter any external service requests; for dial-on-demand hosts that 549538032Speter want to minimize DNS lookups when mail is being queued. For 549638032Speter this to work you will also have to make sure that gethostbyname 549738032Speter of your local host name does not do a DNS lookup. 549838032Speter Improved handling of "out of space" conditions from John Myers of 549938032Speter Carnegie Mellon. 550038032Speter Improved security for mailing to files on systems that have fchmod(2) 550138032Speter support. 550238032Speter Improve "cannot send message for N days" message -- now says "could 550338032Speter not send for past N days". Suggested by Tom Moore of AT&T 550438032Speter Global Information Solutions. 550538032Speter Less misleading Subject: line on messages sent to postmaster only. 550638032Speter From Motonori Nakamura. 550738032Speter Avoid duplicate error messages on bad command line flags. From 550838032Speter Motonori Nakamura. 550938032Speter Better error message for case where ruleset 0 falls off the end 551038032Speter or otherwise does not resolve to a canonical triple. 551138032Speter Fix a problem that could cause multiple bounce messages if a bad 551238032Speter address was sent along with a good address to an SMTP 551338032Speter site where that SMTP site returned a 4yz code in response 551438032Speter to the final dot of the data. Problem reported by David 551538032Speter James of British Telecom. 551638032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 551738032Speter from Alexander Dupuy of System Management ARTS. 551838032Speter Delete duplicates in MX lists -- believe it or not, there are sites 551938032Speter that list the same host twice in an MX list. This deletion 552038032Speter only works on adjacent preferences, so an MX list that 552138032Speter had A=5, B=10, A=15 would leave both As, but one that had 552238032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 552338032Speter just in case there is something weird I haven't thought of. 552438032Speter Suggested by Barry Shein of Software Tool & Die. 552538032Speter SECURITY: .forward files cannot be symbolic links. If they are, 552638032Speter a bad guy can read your private files. 552738032Speter PORTABILITY FIXES: 552838032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 552938032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 553038032Speter University.

This means that the 554438032Speter sizeof operator returns only multiples of 8. 554538032Speter This requires adaptation of code that really 554638032Speter deals with 32 bit or 16 bit fields, such as IP 554738032Speter addresses or nameserver fields.'' 554838032Speter DG/UX 5.4.3 from Mark T.

This can 563338032Speter be used as an alternative to /bin/sh for the "prog" mailer, 563438032Speter giving the local administrator more control over what 563538032Speter programs can be run from sendmail. 563638032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 563738032Speter part of the release proper, and isn't fully supported; in 563838032Speter particular, it does not run on System V based systems and 563938032Speter never will. 564038032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 564138032Speter to allow rmail to compile on systems that don't have 564238032Speter function prototypes and systems that don't have snprintf. 564338032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 564438032Speter lists by transaction delay times so that addresses that 564538032Speter respond quickly get sent first. This is to prevent very 564638032Speter sluggish servers from delaying other peoples' mail. 564738032Speter Contributed by Tony Sanders of BSDI. 564838032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 564938032Speter of BSDI. This has a lot of comments to help people out. 565038032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 565138032Speter put this on the m4 command line. On GNU m4 (which 565238032Speter supports the __file__ primitive) you can run m4 in an 565338032Speter arbitrary directory -- use either: 565438032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 565538032Speter or 565638032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 565738032Speter On other versions of m4 that don't support __file__, you 565838032Speter can use: 565938032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 566038032Speter (Note the trailing slash on the _CF_DIR_ definition.) 566138032Speter Old versions of m4 will default to _CF_DIR_=.. for back 566238032Speter compatibility. 566338032Speter CONFIG: fix mail from <> so it will properly convert to 566438032Speter MAILER-DAEMON on local addresses. 566538032Speter CONFIG: fix code that was supposed to catch colons in host 566638032Speter names. Problem noted by John Gardiner Myers of CMU. 566738032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 566838032Speter From Paul Riddle of the University of Maryland, Baltimore 566938032Speter County. 567038032Speter CONFIG: Catch and reject "." as a host address. 567138032Speter CONFIG: Generalize domaintable to look up all domains, not 567238032Speter just unqualified ones. 567338032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 567438032Speter was never used and didn't work anyway. 567538032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 567638032Speter and d on all mailers in the UUCP class. 567738032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 567838032Speter look for an alias for "user+detail", then for "user+*", and 567938032Speter finally for "user". This is intended for forwarding mail 568038032Speter for system aliases such as root and postmaster to a 568138032Speter centralized hub. 568238032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 568338032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 568438032Speter The F=8 flag is also set on the "relay" mailer, since 568538032Speter this is expected to be another sendmail. 568638032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 568738032Speter the name of the UUCP_RELAY -- in some cases, this is the 568838032Speter wrong value (e.g., when we have local UUCP connections), 568938032Speter and this can create unreplyable addresses. From Chip 569038032Speter Rosenthal of Unicom. 569138032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 569264562Sgshapiro Received: header inserted into all messages. Suggested by 569338032Speter Gary Mills of the University of Manitoba. 569438032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 569543730Speter to get the old behavior. I did this upon observing 569638032Speter that almost everyone needed this feature, and that the 569738032Speter concept I was trying to make happen didn't work with 569838032Speter some user agents anyway. FEATURE(notsticky) still works, 569938032Speter but it is a no-op. 570038032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 570138032Speter names are sent, rather than immediately diagnosing them 570238032Speter as User Unknown. 570338032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 570438032Speter and RELAY_MAILER_ARGS to set the arguments for the 570538032Speter indicated mailers. All default to "IPC $h". Patch from 570638032Speter Larry Parmelee of Cornell University. 570738032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 570838032Speter on the client side" and F=P to get an appropriate 570938032Speter return-path. From Kimmo Suominen. 571038032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 571138032Speter as the local mailer. For addresses of the form "user+detail" 571238032Speter the "detail" part is passed to procmail via the -a flag. 571338032Speter Contributed by Kimmo Suominen. 571438032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 571538032Speter use from mailertables. This lets you execute arbitrary 571638032Speter procmail scripts. Contributed by Kimmo Suominen. 571738032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 571838032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 571938032Speter Paul Southworth of CICNet Systems Support. 572038032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 572138032Speter This causes the null return path to be rewritten as 572238032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 572338032Speter From Michael Hohmuth of Technische Universitat Dresden. 572438032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 572538032Speter list us as the best possible MX record to be treated as 572638032Speter though they were local (essentially, assume that they 572738032Speter are included in $=w). This can cause additional DNS 572838032Speter traffic, but is easier to administer if this fits your 572938032Speter local model. It does not work reliably if there are 573038032Speter multiple hosts that share the best MX preference. 573138032Speter Code contributed by John Oleynick of Rutgers. 573238032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 573338032Speter SHell) instead of /bin/sh as the program used for delivery 573438032Speter to programs. If an argument is included, it is used as 573538032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 573638032Speter assumed. 573738032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 573838032Speter size of messages to the local and procmail mailers 573938032Speter respectively. Contributed by Brad Knowles of the Defense 574038032Speter Information Systems Agency. 574138032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 574238032Speter (just like text outside of angle brackets) in order to 574338032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 574438032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 574538032Speter any real systems any more) and tweak the DOMAIN macro 574638032Speter so that it is less likely that users will accidentally use 574738032Speter the Berkeley defaults. Also, create some generic files 574838032Speter that really can be used in the real world. 574938032Speter CONFIG: Add new configuration macros to set character sets for 575038032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 575138032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 575238032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 575338032Speter The old name will still be accepted for a while at least. 575438032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 575538032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 575638032Speter As with all relays, it can be ``mailer:hostname''. Suggested 575738032Speter by Scott Hutton. 575838032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 575938032Speter by Barb Dijker of Labyrinth Computer Services. 576038032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 576138032Speter performance for large alias files, and this confused many 576238032Speter people. 576338032Speter CONFIG: Add confCF_VERSION to append local information to the 576438032Speter configuration version number displayed during SMTP startup. 576538032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 576638032Speter would only work when locally addressed. Fix from 576738032Speter Edvard Tuinder of Cistron Internet Services. 576838032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 576943730Speter "n" (CheckAliases) is set when rebuilding alias database. 577038032Speter Based on code contributed by Claude Marinier. 577138032Speter CONFIG: Allow mailertable to have values of the form 577238032Speter ``error:code message''. The ``code'' is a status code 577338032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 577438032Speter Contributed by David James <dwj@agw.bt.co.uk>. 577538032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 577638032Speter sender domains that will be replaced with the masquerade name. 577738032Speter These domains will not be treated as local, but if mail passes 577838032Speter through with sender addresses in those domains they will be 577938032Speter replaced by the masquerade name. These can also be specified 578038032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 578138032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 578238032Speter as well as the header. Substantial improvements to this 578338032Speter code were contributed by Per Hedeland. 578438032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 578538032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 578638032Speter by Kimmo Suominen. 578738032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 578838032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 578938032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 579038032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 579138032Speter UUCP addressing.

590264562Sgshapiro8.6.12/8.6.12 1995/03/28 590338032Speter Fix to IDENT code (it was getting the size of the reply buffer 590438032Speter too small, so nothing was ever accepted). Fix from several 590538032Speter people, including Allan Johannesen, Shane Castle of the 590638032Speter Boulder County Information Services, and Jeff Smith of 590738032Speter Warwick University (all arrived within a few hours of 590838032Speter each other!). 590938032Speter Fix a problem that could cause large jobs to run out of 591038032Speter file descriptors on systems that use vfork() rather 591138032Speter than fork(). 591238032Speter 591364562Sgshapiro8.6.11/8.6.11 1995/03/08 591438032Speter The ``possible attack'' message would be logged more often 591538032Speter than necessary if you are using Pine as a user agent. 591638032Speter The wrong host would be reported in the ``possible attack'' 591738032Speter message when attempted from IDENT. 591838032Speter In some cases the syslog buffer could be overflowed when 591938032Speter reporting the ``possible attack'' message. This can 592038032Speter cause denial of service attacks. Truncate the message 592138032Speter to 80 characters to prevent this problem. 592238032Speter When reading the IDENT response a loop is needed around the 592338032Speter read from the network to ensure that you don't get 592438032Speter partial lines. 592538032Speter Password entries without any shell listed (that is, a null 592638032Speter shell) wouldn't match as "ok". Problem noted by 592738032Speter Rob McMahon. 592838032Speter When running BIND 4.9.x a problem could occur because the 592938032Speter _res.options field is initialized differently than it 593038032Speter was historically -- this requires that sendmail call 593138032Speter res_init before it tweaks any bits. 593238032Speter Fix an incompatibility in openxscript() between the file open mode 593338032Speter and the stdio mode passed to fdopen. This caused UnixWare 593438032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 593538032Speter Novell Labs Europe. 593638032Speter Fix problem with static linking of local getopt routine when 593738032Speter using GNU's ld command. Fix from John Kennedy of 593838032Speter Cal State Chico. 593938032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 594238032Speter and Liudvikas Bukys. 594338032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 594438032Speter from Spider Boardman. 594538032Speter CONFIG: No changes (version number only, to keep it in sync 594638032Speter with the binaries). 594738032Speter 594864562Sgshapiro8.6.10/8.6.10 1995/02/10 594938032Speter SECURITY: Diagnose bogus values to some command line flags that 595038032Speter could allow trash to get into headers and qf files. 595138032Speter Validate the name of the user returned by the IDENT protocol. 595238032Speter Some systems that really dislike IDENT send intentionally 595338032Speter bogus information. Problem pointed out by Michael Bushnell 595438032Speter of the Free Software Foundation. Has some security 595538032Speter implications. 595638032Speter Fix a problem causing error messages about DNS problems when 595738032Speter the host name contained a percent sign to act oddly 595838032Speter because it was passed as a printf-style format string. 595938032Speter In some cases this could cause core dumps. 596038032Speter Avoid possible buffer overrun in returntosender() if error 596138032Speter message is quite long. From Fletcher Mattox of the 596238032Speter University of Texas. 596338032Speter Fix a problem that would silently drop "too many hops" error 596438032Speter messages if and only if you were sending to an alias. 596538032Speter From Jon Giltner of the University of Colorado and 596638032Speter Dan Harton of Oak Ridge National Laboratory. 596738032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 596838032Speter set and e->e_message was null. Fix from Bruce Nagel of 596938032Speter Data General. 597038032Speter Fix problem that can still cause df files to be left around 597138032Speter after "hop count exceeded" messages. Fix from Andrew 597238032Speter Chang and Shau-Ping Lo of SunSoft. 597338032Speter Fix a problem that can cause buffer overflows on very long 597438032Speter user names (as might occur if you piped to a program 597538032Speter with a lot of arguments). 597638032Speter Avoid returning an error and re-queueing if the host signature 597738032Speter is null; this can occur on addresses like ``user@.''. 597838032Speter Problem noted by Wesley Craig and the University of 597938032Speter Michigan. 598038032Speter Avoid possible calls to malloc(0) if MCI caching is turned 598138032Speter off. Bug fix from Pierre David of the Laboratoire 598238032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 598338032Speter Universite de Versailles - St Quentin, and Jacky 598438032Speter Thibault. 598538032Speter Make a local copy of the line being sent via senttolist() -- in 598638032Speter some cases, buffers could get trashed by map lookups 598738032Speter causing it to do unexpected things. This also simplifies 598838032Speter some of the map code. 598938032Speter CONFIG: No changes (version number only, to keep it in sync 599038032Speter with the binaries). 599138032Speter 599264562Sgshapiro8.6.9/8.6.9 1994/04/19 599338032Speter Do all mail delivery completely disconnected from any terminal. 599438032Speter This provides consistency with daemon delivery and 599538032Speter may have some security implications. 599638032Speter Make sure that malloc doesn't get called with zero size, 599738032Speter since that fails on some systems. Reported by Ed 599838032Speter Hill of the University of Iowa. 599938032Speter Fix multi-line values for $e (SMTP greeting message). Reported 600038032Speter by Mike O'Connor of Ford Motor Company. 600138032Speter Avoid syserr if no NIS domain name is defined, but the map it 600238032Speter is trying to open is optional. From Win Bent of USC. 600338032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 600438032Speter Hesiod support for UDB from Todd Miller of the University of 600538032Speter Colorado. Use "hesiod" as the service name in the U 600638032Speter option. 600738032Speter Fix a problem that failed to set the "authentic" host name (that 600838032Speter is, the one derived from the socket info) if you called 600938032Speter sendmail -bs from inetd. Based on code contributed by 601038032Speter Todd Miller (this problem was also reported by Guy Helmer 601138032Speter of Dakota State University). This also fixes a related 601238032Speter problem reported by Liudvikas Bukys of the University of 601338032Speter Rochester. 601438032Speter Parameterize "nroff -h" in all the Makefiles so people with 601538032Speter variant versions can use them easily. Suggested by 601638032Speter Peter Collinson of Hillside Systems. 601738032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 601838032Speter spaces between parameters instead of one. Reported by 601938032Speter Valdis Kletnieks of Virginia Tech. 602038032Speter Reduce the number of system calls during message collection by 602138032Speter using global timeouts around the collect() loop. This 602238032Speter code was contributed by Eric Wassenaar. 602338032Speter If the initial hostname name gathering results in a name 602438032Speter without a dot (usually caused by NIS misconfiguration) 602538032Speter and BIND is compiled in, directly access DNS to get 602638032Speter the canonical name. This should make life easier for 602738032Speter Solaris systems. If it still can't be resolved, and 602838032Speter if the name server is listed as "required", try again 602938032Speter in 30 seconds. If that also fails, exit immediately to 603038032Speter avoid bogus "config error: mail loops back to myself" 603138032Speter messages. 603238032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 603338032Speter message to explain how much space was available and 603438032Speter sound a bit less threatening. Suggested by Stan Janet 603538032Speter of the National Institute of Standards and Technology. 603638032Speter If mail is delivered to an alias that has an owner, deliver any 603738032Speter requested return-receipt immediately, and strip the 603838032Speter Return-Receipt-To: header from the subsequent message. 603938032Speter This prevents a certain class of denial of service 604038032Speter attack, arguably gives more reasonable semantics, and 604138032Speter moves things more towards what will probably become a 604238032Speter network standard. Suggested by Christopher Davis of 604338032Speter Kapor Enterprises. 604438032Speter Add a "noreceipts" privacy flag to turn off all return receipts 604538032Speter without recompiling. 604638032Speter Avoid printing ESMTP parameters as part of the error message 604738032Speter if there are errors during parsing. This change is 604838032Speter purely cosmetic. 604938032Speter Avoid sending out error messages during the collect phase of 605038032Speter SMTP; there is an MVS mailer from UCLA that gets 605138032Speter confused by this. Of course, I think it's their bug.... 605238032Speter Check for the $j macro getting undefined, losing a dot, or getting 605338032Speter lost from $=w in the daemon before accepting a connection; 605438032Speter if it is, it dumps state, prints a LOG_ALERT message, 605538032Speter and drops core for debugging. This is an attempt to 605638032Speter track down a bug that I thought was long since gone. 605738032Speter If you see this, please forward the log fragment to 605838032Speter sendmail@sendmail.ORG. 605938032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 606038032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 606138032Speter Wolfhugel. 606238032Speter Instead of trying to truncate the listen queue for the server 606338032Speter SMTP port when the load average is too high, just close 606438032Speter the port completely and reopen it later as needed. 606538032Speter This ensures that the other end gets a quick "connection 606638032Speter refused" response, and that the connection can be 606738032Speter recovered later. In particular, some socket emulations 606838032Speter seem to get confused if you tweak the listen queue 606938032Speter size around and can never start listening to connections 607038032Speter again. The down side is that someone could start up 607138032Speter another daemon process in the interim, so you could 607238032Speter have multiple daemons all not listening to connections; 607338032Speter this could in turn cause the sendmail.pid file to be 607438032Speter incorrect. A better approach might be to accept the 607538032Speter connection and give a 421 code, but that could break 607643730Speter other mailers in mysterious ways and have paging behavior 607738032Speter implications. 607838032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 607938032Speter set debugging on the wrong socket. From Eric Wassenaar. 608038032Speter When creating a df* temporary file, be sure you truncate any 608138032Speter existing data in the file -- otherwise system crashes 608238032Speter and the like could result in extra data being sent. 608338032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 608438032Speter doc directory. This includes some additional 608538032Speter information. 608638032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 608738032Speter of recipient envelope addresses. This should have been 608838032Speter handled by the $&h trick, but broke if people were 608938032Speter mixing domainized and UUCP addresses. They should 609038032Speter probably have converted all the way over to uucp-uudom 609138032Speter instead of uucp-{new,old}, but the failure mode was to 609238032Speter loop the mail, which was bad news. 609338032Speter Portability fixes: 609438032Speter Newer BSDI systems (several people). 609538032Speter Older BSDI systems from Christophe Wolfhugel. 609638032Speter Intergraph CLIX, from Paul Southworth of CICNet. 609738032Speter UnixWare, from Evan Champion. 609838032Speter NetBSD from Adam Glass. 609938032Speter Solaris from Quentin Campbell of the University of 610038032Speter Newcastle upon Tyne. 610138032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 610238032Speter Corporation. 610338032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 610438032Speter SunOS (it has setsid() and setvbuf() calls) from 610538032Speter Jonathan Kamens of OpenVision Technologies. 610638032Speter HP-UX from Tor Lillqvist. 610738032Speter New Files: 610838032Speter src/Makefile.CLIX 610938032Speter src/Makefile.NCR3000 611038032Speter doc/changes/Makefile 611138032Speter doc/changes/changes.me 611238032Speter doc/changes/changes.ps 611338032Speter 611464562Sgshapiro8.6.8/8.6.6 1994/03/21 611538032Speter SECURITY: it was possible to read any file as root using the 611638032Speter E (error message) option. Reported by Richard Jones; 611738032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 611838032Speter 611964562Sgshapiro8.6.7/8.6.6 1994/03/14 612038032Speter SECURITY: it was possible to get root access by using weird 612138032Speter values to the -d flag. Thanks to Alain Durand of 612238032Speter INRIA for forwarding me the notice from the bugtraq 612338032Speter list. 612438032Speter 612564562Sgshapiro8.6.6/8.6.6 1994/03/13 612638032Speter SECURITY: the ability to give files away on System V-based 612738032Speter systems proved dangerous -- don't run as the owner 612838032Speter of a :include: file on a system that allows giveaways. 612938032Speter Unfortunately, this also applies to determining a 613038032Speter valid shell. 613138032Speter IMPORTANT: Previous versions weren't expiring old connections 613238032Speter in the connection cache for a long time under some 613338032Speter circumstances. This could result in resource exhaustion, 613438032Speter both at your end and at the other end. This checks the 613538032Speter connections for timeouts much more frequently. From 613638032Speter Doug Anderson of NCSC. 613738032Speter Fix a glitch that snuck in that caused programs to be run as 613838032Speter the sender instead of the recipient if the mail was 613938032Speter from a local user to another local user. From 614038032Speter Motonori Nakamura of Kyoto University. 614138032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 614238032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 614338032Speter Bryan Costales of ICSI. 614438032Speter Change the method used to declare the "statfs" availability; 614538032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 614638032Speter tweaking in conf.c, there is a single #define called 614738032Speter SFS_TYPE which takes on one of six values (SFS_NONE 614838032Speter for no statfs availability, SFS_USTAT for the ustat(2) 614938032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 615038032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 615138032Speter statfs(2) call with the declarations in <sys/vfs.h>, 615238032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 615338032Speter Fix glitch in NetInfo support that could return garbage if 615438032Speter there was no "/locations/sendmail" property. From 615538032Speter David Meyer of the University of Virginia. 615638032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 615738032Speter to allow Linux to turn it off even though it is a 615838032Speter BSD-like system. 615938032Speter Allow setting of "ident" timeout to zero to turn off the ident 616038032Speter protocol entirely. 616138032Speter Make 7-bit stripping local to a connection (instead of to a 616238032Speter mailer); this allows you to specify that SMTP is a 616338032Speter 7-bit channel, but revert to 8-bit should it advertise 616438032Speter that it supports 8BITMIME. You still have to specify 616538032Speter mailer flag 7 to get this stripping at all. 616638032Speter Improve makesendmail script so it handles more cases automatically. 616738032Speter Tighten up restrictions on taking ownership of :include: files 616838032Speter to avoid problems on systems that allow you to give away 616938032Speter files. 617038032Speter Fix a problem that made it impossible to rebuild the alias 617138032Speter file if it was on a read-only file system. From 617238032Speter Harry Edmon of the University of Washington. 617338032Speter Improve MX randomization function. From John Gardiner Myers 617438032Speter of CMU. 617538032Speter Fix a minor glitch causing a bogus message to be printed (used 617638032Speter %s instead of %d in a printf string for the line number) 617738032Speter when a bad queue file was read. From Harry Edmon. 617838032Speter Allow $s to remain NULL on locally generated mail. I'm not 617938032Speter sure this is necessary, but a lot of people have complained 618038032Speter about it, and there is a legitimate question as to whether 618138032Speter "localhost" is legal as an 822-style domain. 618238032Speter Fix a problem with very short line lengths (mailer L= flag) in 618338032Speter headers. This causes a leading space to be added onto 618438032Speter continuation lines (including in the body!), and also 618538032Speter tries to wrap headers containing addresses (From:, To:, 618638032Speter etc) intelligently at the shorter line lengths. Problem 618738032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 618838032Speter Log the real user name when logging syserrs, since these can have 618938032Speter security implications. Suggested by several people. 619038032Speter Fix address logging of cached connections -- it used to always 619138032Speter log the numeric address as zero. This is a somewhat 619238032Speter bogus implementation in that it does an extra system 619338032Speter call, but it should be an inexpensive one. Fix from 619438032Speter Motonori Nakamura. 619538032Speter Tighten up handling of short syslog buffers even more -- there 619638032Speter were cases where the outgoing relay= name was too long 619738032Speter to share a line with delay= and mailer= logging. 619838032Speter Limit the overhead on split envelopes to one open file descriptor 619938032Speter per envelope -- previously the overhead was three 620038032Speter descriptors. This was in response to a problem reported 620138032Speter by P{r (Pell) Emanuelsson. 620238032Speter Fixes to better handle the case of unexpected connection closes; 620338032Speter this redirects the output to the transcript so the info 620438032Speter is not lost. From Eric Wassenaar. 620538032Speter Fix potential string overrun if you macro evaluate a string that 620638032Speter has a naked $ at the end. Problem noted by James Matheson 620738032Speter <jmrm@eng.cam.ac.uk>. 620838032Speter Make default error number on $#error messages 553 (``Requested 620938032Speter action not taken: mailbox name not allowed'') instead of 621038032Speter 501 (``Syntax error in parameters or arguments'') to 621138032Speter avoid bogus "protocol error" messages. 621238032Speter Strip off any existing trailing dot on names during $[ ... $] 621338032Speter lookup. This prevents it from ending up with two dots 621438032Speter on the end of dot terminated names. From Wesley Craig 621538032Speter of the University of Michigan and Bryan Costales of ICSI. 621638032Speter Clean up file class reading so that the debugging information is 621738032Speter more informative. It hadn't been using setclass, so you 621838032Speter didn't see the class items being added. 621938032Speter Avoid core dump if you are running a version of sendmail where 622038032Speter NIS is compiled in, and you specify an NIS map, but 622138032Speter NIS is not running. Fix from John Oleynick of 622238032Speter Rutgers. 622338032Speter Diagnose bizarre case where res_search returns a failure value, 622438032Speter but sets h_errno to a success value. 622538032Speter Make sure that "too many hops" messages are considered important 622638032Speter enough to send an error to the Postmaster (that is, the 622738032Speter address specified in the P option). This fix should 622838032Speter help problems that cause the df file to be left around 622938032Speter sometimes -- unfortunately, I can't seem to reproduce 623038032Speter the problem myself. 623138032Speter Avoid core dump (null pointer reference) on EXPN command; this 623238032Speter only occurred if your log level was set to 10 or higher 623338032Speter and the target account was an alias or had a .forward file. 623438032Speter Problem noted by Janne Himanka. 623538032Speter Avoid "denial of service" attacks by someone who is flooding your 623638032Speter SMTP port with bad commands by shutting the connection 623738032Speter after 25 bad commands are issued. From Kyle Jones of 623838032Speter UUNET. 623938032Speter Fix core dump on error messages with very long "to" buffers; 624038032Speter fmtmsg overflows the message buffer. Fixed by trimming 624138032Speter the to address to 203 characters. Problem reported by 624238032Speter John Oleynick. 624338032Speter Fix configuration for HASFLOCK -- there were some spots where 624438032Speter a #ifndef was incorrectly #ifdef. Pointed out by 624538032Speter George Baltz of the University of Maryland. 624638032Speter Fix a typo in savemail() that could cause the error message To: 624738032Speter lists to be incorrect in some places. From Motonori 624838032Speter Nakamura. 624938032Speter Fix a glitch that can cause duplicate error messages on split 625038032Speter envelopes where an address on one of the lists has a 625138032Speter name server failure. Fix from Voradesh Yenbut of the 625238032Speter University of Washington. 625338032Speter Fix possible bogus pointer reference on ESMTP parameters that 625438032Speter don't have an ``=value'' part. 625538032Speter CNAME loops caused an error message to be generated, but also 625638032Speter re-queued the message. Changed to just re-queue the 625738032Speter message (it's really hard to just bounce it because 625838032Speter of the weird way the name server works in the presence 625938032Speter of CNAME loops). Problem noted by James M.R.Matheson 626038032Speter of Cambridge University. 626138032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 626238032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 626338032Speter user name. Suggested by Andreas Stolcke of ICSI. 626438032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 626538032Speter override it easily in the Makefile -- that is, you can 626638032Speter turn it off using -DNAMED_BIND=0. 626738032Speter If a gethostbyname(...) of an address with a trailing dot fails, 626838032Speter try it without the trailing dot. This is because if 626938032Speter you have a version of gethostbyname() that falls back 627038032Speter to NIS or the /etc/hosts file it will fail to find 627138032Speter perfectly reasonable names that just don't happen to 627238032Speter be dot terminated in the hosts file. You don't want to 627338032Speter strip the dot first though because we're trying to ensure 627438032Speter that country names that match one of your subdomains get 627538032Speter a chance. 627638032Speter PRALIASES: fix bogus output on non-null-terminated strings. 627738032Speter From Bill Gianopoulos of Raytheon. 627838032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 627938032Speter This was in code intended to only catch the self-literal 628038032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 628138032Speter IP address), but the code was broken. However, it will 628238032Speter still do this if $M is defined; this is necessary to 628338032Speter get client configurations to work (sigh). Note that this 628438032Speter means that $M overrides :mailname entries in the user 628538032Speter database! Problem noted by Paul Southworth. 628638032Speter CONFIG: Fix definition of Solaris help file location. From 628738032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 628838032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 628938032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 629038032Speter and USENET_MAILER_MAX to tweak the maximum message 629138032Speter size for various mailers. 629238032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 629338032Speter instead of assuming that it is "inews" for consistency 629438032Speter with other mailers. From Michael Corrigan of UC San Diego. 629538032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 629638032Speter qualify the address in the SMTP envelope as user@{relay|hub} 629738032Speter instead of user@$j. From Bill Wisner of The Well. 629838032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 629938032Speter CONFIG: Don't turn off case mapping of user names in the local 630038032Speter mailer for IRIX. This was different than most every other 630138032Speter system. 630238032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 630338032Speter envelope. Noted by Thierry Besancon 630438032Speter <besancon@excalibur.ens.fr>. 630538032Speter CONFIG: Don't include -z by default on uux line -- most systems 630638032Speter don't want it set by default. Pointed out by Philippe 630738032Speter Michel of Thomson CSF. 630838032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 630938032Speter host name was foo.bar.ray.com and you matched against 631038032Speter ".ray.com", the old implementation bound %1 to "bar" 631138032Speter instead of "foo.bar". Also, allow "." in the mailertable 631238032Speter to match anything -- essentially, take over SMART_HOST. 631338032Speter This also moves matching of explicit local host names 631438032Speter before the mailertable so they don't have to be special 631538032Speter cased in the mailertable data. Reported by Bill 631638032Speter Gianopoulos of Raytheon; the fix for the %1 binding 631738032Speter problem was contributed by Nicholas Comanos of the 631838032Speter University of Sydney. 631938032Speter CONFIG: Don't include "root" in class $=L (users to deliver 632038032Speter locally, even if a hub or relay exists) by default. 632138032Speter This is because of the known bug where definition of 632238032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 632338032Speter both and deliver into the local mailbox. 632438032Speter CONFIG: Move up bitdomain and uudomain handling so that they 632538032Speter are done before .UUCP class matching; uudomain was 632638032Speter reported as ineffective before. This also frees up 632738032Speter diversion 8 for future use. Problem reported by Kimmo 632838032Speter Suominen. 632938032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 633038032Speter into host names. As pointed out by Jonathan Kamens, 633138032Speter these are often used because either the forward or reverse 633238032Speter mapping is broken; this translation makes it broken again. 633338032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 633438032Speter Suominen. 633538032Speter Portability fixes: 633638032Speter Unicos from David L. Kensiski of Sterling Software. 633738032Speter DomainOS from Don Lewis of Silicon Systems. 633838032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 633938032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 634038032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 634138032Speter BSD/386 from Tony Sanders of BSDI. 634238032Speter Apollo from Eric Wassenaar. 634338032Speter DGUX from Doug Anderson. 634438032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 634538032Speter NEW FILES: 634638032Speter src/Makefile.DomainOS 634738032Speter src/Makefile.PTX 634838032Speter src/Makefile.SunOS.5.1 634938032Speter src/Makefile.SunOS.5.2 635038032Speter src/Makefile.SunOS.5.x 635138032Speter src/mailq.1 635238032Speter cf/ostype/domainos.m4 635338032Speter doc/op/Makefile 635438032Speter doc/intro/Makefile 635538032Speter doc/usenix/Makefile 635638032Speter 635764562Sgshapiro8.6.5/8.6.5 1994/01/13 635838032Speter Security fix: /.forward could be owned by anyone (the test 635938032Speter to allow root to own any file was backwards). From 636038032Speter Bob Campbell at U.C. Berkeley. 636138032Speter Security fix: group ids were not completely set when programs 636238032Speter were invoked. This caused programs to have group 636338032Speter permissions they should not have had (usually group 636438032Speter daemon instead of their own group). In particular, 636538032Speter Perl scripts would refuse to run. 636638032Speter Security: check to make sure files that are written are not 636738032Speter symbolic links (at least under some circumstances). 636838032Speter Although this does not respond to a specific known 636938032Speter attack, it's just a good idea. Suggested by 637038032Speter Christian Wettergren. 637138032Speter Security fix: if a user had an NFS mounted home directory on 637238032Speter a system with a restricted shell listed in their 637338032Speter /etc/passwd entry, they could still execute any 637438032Speter program by putting that in their .forward file. 637538032Speter This fix prevents that by insisting that their shell 637638032Speter appear in /etc/shells before allowing a .forward to 637738032Speter execute a program or write a file. You can disable 637838032Speter this by putting "*" in /etc/shells. It also won't 637938032Speter permit world-writable :include: files to reference 638038032Speter programs or files (there's no way to disable this). 638143730Speter These behaviors are only one level deep -- for 638238032Speter example, it is legal for a world-writable :include: 638338032Speter file to reference an alias that writes a file, on 638438032Speter the assumption that the alias file is well controlled. 638538032Speter Security fix: root was not treated suspiciously enough when 638638032Speter looking into subdirectories. This would potentially 638738032Speter allow a cracker to examine files that were publicly 638838032Speter readable but in a non-publicly searchable directory. 638938032Speter Fix a problem that causes an error on QUIT on a cached 639038032Speter connection to create problems on the current job. 639138032Speter These are typically unrelated, so errors occur in 639238032Speter the wrong place. 639338032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 639438032Speter runs more responsive to load average, and fixes a 639538032Speter problem that ignored the load average in locally 639638032Speter generated mail. From Eric Wassenaar. 639738032Speter Fix possible core dump on aliases with null LHS. From 639838032Speter John Orthoefer of BB&N. 639938032Speter Revert to using flock() whenever possible -- there are just 640038032Speter too many bugs in fcntl() locking, particularly over 640138032Speter NFS, that cause sendmail to fail in perverse ways. 640238032Speter Fix a bug that causes the connection cache to get confused 640338032Speter when sending error messages. This resulted in 640438032Speter "unexpected close" messages. It should fix itself 640538032Speter on the following queue run. Problem noted by 640638032Speter Liudvikas Bukys of the University of Rochester. 640738032Speter Include $k in $=k as documented in the Install & Op Guide. 640838032Speter This seems odd, but it was documented.... From 640938032Speter Michael Corrigan of UCSD. 641038032Speter Fix problem that caused :include:s from alias files to be 641138032Speter forced to be owned by root instead of daemon 641238032Speter (actually DefUid). From Tim Irvin. 641338032Speter Diagnose unrecognized I option values -- from Mortin Forssen 641438032Speter of the Chalmers University of Technology. 641538032Speter Make "error" mailer work consistently when there is no error 641638032Speter code associated with it -- previously it returned OK 641738032Speter even though there was a real problem. Now it assumes 641838032Speter EX_UNAVAILABLE. 641938032Speter Fix bug that caused the last header line of messages that had 642038032Speter no body and which were terminated with EOF instead of 642138032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 642238032Speter Fix core dump on SMTP mail to programs that failed -- it tried 642338032Speter to go to a "next MX host" when none existed, causing 642438032Speter a core dump. From der Mouse at McGill University. 642538032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 642638032Speter this makes it easier to turn it off (using 642738032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 642838032Speter Fix YP_MASTER_NAME store to use the unupdated result of 642938032Speter gethostname() (instead of myhostname(), which tries 643038032Speter to fully qualify the name) to be consistent with 643138032Speter SunOS. If your hostname is unqualified, this fixes 643238032Speter transfers to slave servers. Bug noted by Keith 643338032Speter McMillan of Ameritech Services, Inc. 643438032Speter Fix Ultrix problem: gethostbyname() can return a very large 643538032Speter (> 500) h_length field, which causes the sockaddr 643638032Speter to be trashed. Use the size of the sockaddr instead. 643738032Speter Fix from Bob Manson of Ohio State. 643838032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 643938032Speter defined -- this confuses gethostbyname on hosts 644038032Speter file lookups, which doesn't understand the trailing 644138032Speter dot convention. 644238032Speter Log SMTP server subprocesses that die with a signal instead 644338032Speter of from a clean exit. 644438032Speter If you don't have option "I" set, don't assume that a DNS 644538032Speter "host unknown" message is authoritative -- it 644638032Speter might still be found in /etc/hosts. 644738032Speter Fix a problem that would cause Deferred: messages to be sent 644838032Speter as the subject of an error message, even though the 644938032Speter actual cause of a message was more severe than that. 645038032Speter Problem noted by Chris Seabrook of OSSI. 645138032Speter Fix race condition in DBM alias file locking. From Kyle 645238032Speter Jones of UUNET. 645338032Speter Limit delivery syslog line length to avoid bugs in some 645438032Speter versions of syslog(3). This adds a new compile time 645538032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 645638032Speter University, which is in turn derived from IDA. 645738032Speter Fix quotes inside of comments in addresses -- previously 645838032Speter it insisted that they be balanced, but the 822 spec 645938032Speter says that they should be ignored. 646038032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 646138032Speter debugging). This also evaluates ruleset 89, if set 646238032Speter (with the null input), and logs the result. This 646338032Speter should be used sparingly, since the rewrite process 646438032Speter is not reentrant. 646538032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 646638032Speter documented in the Bat Book. 646738032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 646838032Speter return an error message and did not requeue the message. 646938032Speter Fix based on code from Roland Dirlewanger of 647038032Speter Reseau Regional Aquarel, Bordeaux, France. 647138032Speter Fix a problem that caused a seg fault if you got a 421 error 647238032Speter code during some parts of connection initialization. 647338032Speter I've only seen this when talking to buggy mailers on 647438032Speter the other end, but it shouldn't give a seg fault in 647538032Speter any case. From Amir Plivatsky. 647638032Speter Fix core dump caused by a ruleset call that returns null. 647738032Speter Fix from Bryan Costales of ICSI. 647838032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 647938032Speter of Kyoto University. 648038032Speter Fix a possible problem with very long input lines in setproctitle. 648138032Speter From P{r Emanuelsson. 648238032Speter Avoid putting "This is a warning message" out on return receipts. 648338032Speter Suggested by Douglas Anderson. 648438032Speter Detect loops caused by recursive ruleset calls. Suggested by 648538032Speter Bryan Costales. 648638032Speter Initialize non-alias maps during alias rebuilds -- they may be 648738032Speter needed for parsing. Problem noted by Douglas Anderson. 648838032Speter Log sender address even if no message was collected in SMTP 648938032Speter (e.g., if all RCPTs failed). Suggested by Motonori 649038032Speter Nakamura. 649138032Speter Don't reflect the owner-list contents into the envelope sender 649238032Speter address if the value contains ", :, /, or | (to avoid 649338032Speter illegal addresses appearing there). 649438032Speter Efficiency hack for toktype macro -- from Craig Partridge of 649538032Speter BB&N. 649638032Speter Clean up DNS error printing so that a host name is always 649738032Speter included. 649838032Speter Remember to set $i during queue runs. Reported by Stephen 649938032Speter Campbell of Dartmouth University. 650038032Speter If the environment variable HOSTALIASES is set, use it during 650138032Speter canonification as the name of a file with per-user host 650238032Speter translations so that headers are properly mapped. Reported 650338032Speter by Anne Bennett of Concordia University. 650438032Speter Avoid printing misleading error message if SMTP mailer (not 650538032Speter using [IPC]) should die on a core dump. 650638032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 650738032Speter by the other end closing the connection. From 650838032Speter Dave Morrison of Oracle. 650938032Speter Improve several of the error messages printed by "mailq" 651038032Speter to include a host name or other useful information. 651138032Speter Add NetInfo preliminary support for NeXT systems. From Vince 651238032Speter DeMarco. 651338032Speter Fix a glitch that sometimes caused :include:s that pointed to 651438032Speter NFS filesystems that were down to give an "aliasing/ 651538032Speter forwarding loop broken" message instead of queueing 651638032Speter the message for retry. Noted by William C Fenner of 651738032Speter the NRL Connection Machine Facility. 651838032Speter Fix a problem that could cause a core dump if the input sequence 651938032Speter had (or somehow acquired) a \231 character. 652038032Speter Make sure that route-addrs always have <angle brackets> around 652138032Speter them in non-SMTP envelopes (SMTP envelopes already do 652238032Speter this properly). 652338032Speter Avoid weird headers on unbalanced punctuation of the form: 652438032Speter ``Joe User <user)'' -- this caused reference to the 652538032Speter null macro. Fix from Rick McCarty of IO.COM. 652638032Speter Fix a problem that caused an alias "user: user@local.host" to 652738032Speter not have the QNOTREMOTE bit set; this caused configs 652838032Speter to act as if FEATURE(notsticky) was defined even when 652938032Speter it was not. The effect of the problem was to make it 653038032Speter very hard to to set up satellite sites that had a few 653138032Speter local accounts, with everything else forwarded to a 653238032Speter corporate hub. Reported by Detlef Drewanz of the 653338032Speter University of Rostock and Mark Frost of NCD. 653438032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 653538032Speter addresses. This is more efficient (fewer name server 653638032Speter calls) and fixes certain unusual configurations, such 653738032Speter as those that have ruleset 4 do something that is 653838032Speter non-idempotent unless a mailer-specific ruleset did 653938032Speter something else. Problem reported by Brian J. Coan 654038032Speter of the Institute for Global Communications. 654138032Speter Fix the "obsolete argument" routine in main to better understand 654238032Speter new arguments. For example, if you used ``sendmail 654338032Speter -C config -v -q'' it would choke on the -q because 654438032Speter the -C would stop looking for old-format arguments. 654538032Speter Fix the code that was intended to allow two users to forward their 654638032Speter mail to the same program and have them appear unique. 654738032Speter Portability fixes for: 654838032Speter SCO UNIX from Murray Kucherawy. 654938032Speter SCO Open Server 3.2v4 from Philippe Brand. 655038032Speter System V Release 4 from Rick Ellis and others. 655138032Speter OSF/1 from Steve Campbell. 655238032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 655338032Speter of Stoner Associates. 655438032Speter Motorola SysV88 from Kevin Johnson of Motorola. 655538032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 656938032Speter of the config file has moved to /usr/lib 657038032Speter to match the HP-UX version of sendmail. 657138032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 657238032Speter since this is intended only for internal use, the 657338032Speter usual RFC 821/822/1123 rules can be relaxed. The 657438032Speter main point of this is to avoid munging (ugh) UUCP 657538032Speter addresses when relaying internally. 657638032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 657738032Speter syntax addresses delivered via UUCP. Solution 657838032Speter provided by Peter Wemm. 657938032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 658038032Speter zero; it caused double @ signs in addresses. From 658138032Speter Irving Reid of the University of Toronto. 658238032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 658338032Speter from Markku Toijala of ICL Personal Systems Oy. 658438032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 658538032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 658638032Speter that made it hard to recognize your own pseudodomain 658738032Speter names. 658838032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 658938032Speter rather than letting them get "local configuration 659038032Speter error"s. Problem noted by John Gardiner Myers. 659138032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 659238032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 659338032Speter has uucp-dom semantics but old UUCP syntax. This 659438032Speter also permits "uucp-old" as an alias for "uucp" and 659538032Speter "uucp-new" as a synonym for "suucp" for consistency. 659638032Speter CONFIG: add POP mailer support (from Kimmo Suominen 659738032Speter <kim@grendel.lut.fi>). 659838032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 659938032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 660038032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 660138032Speter was set; it would get an additional @masquerade.host 660238032Speter added to the address. Problem noted by Peter Wan 660338032Speter of Georgia Tech. 660438032Speter CONFIG: make sure that the local UUCP name is in $=w. From 660538032Speter Jim Murray of Stratus. 660638032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 660738032Speter mailer flag. Briefly, if you are sending to host 660838032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 660938032Speter "foo!baz" remains "foo!baz", and anything else has 661038032Speter the local name prepended. 661138032Speter CONFIG: portability fixes for HP-UX. 661238032Speter DOC: several minor problems fixed in the Install & Op Guide. 661338032Speter MAKEMAP: fix core dump problem on lines that are too long or 661438032Speter which lack newline.

From Tom Ferrin of UC 661738032Speter San Francisco Computer Graphics Lab. 661838032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 661938032Speter On HP-UX, /etc/sendmail.cf has been moved to 662038032Speter /usr/lib/sendmail.cf to match HP sendmail. 662138032Speter Permissions have been tightened up on world-writable 662238032Speter :include: files and accounts that have shells 662338032Speter that are not listed in /etc/shells. This may 662438032Speter cause some .forward files that have worked 662538032Speter before to start failing. 662638032Speter SIGUSR1 dumps some state to the log. 662738032Speter NEW FILES: 662838032Speter src/Makefile.DGUX 662938032Speter src/Makefile.Dynix 663038032Speter src/Makefile.FreeBSD 663138032Speter src/Makefile.Mach386 663238032Speter src/Makefile.NetBSD 663338032Speter src/Makefile.RISCos 663438032Speter src/Makefile.SCO 663538032Speter src/Makefile.SVR4 663638032Speter src/Makefile.Titan 663738032Speter cf/mailer/pop.m4 663838032Speter cf/ostype/bsdi1.0.m4 663938032Speter cf/ostype/dgux.m4 664038032Speter cf/ostype/dynix3.2.m4 664138032Speter cf/ostype/sco3.2.m4 664238032Speter makemap/Makefile.dist 664338032Speter praliases/Makefile.dist 664438032Speter 664564562Sgshapiro8.6.4/8.6.4 1993/10/31 664638032Speter Repair core-dump problem (write to read-only memory segment) 664738032Speter if you fall back to the return-to-Postmaster case in 664838032Speter savemail. Problem reported by Richard Liu. 664938032Speter Immediately diagnose bogus sender addresses in SMTP. This 665038032Speter makes quite certain that crackers can't use this 665138032Speter class of attack. 665238032Speter Reliability Fix: check return value from fclose() and fsync() 665338032Speter in a few critical places. 665438032Speter Minor problem in initsys() that reversed a condition for 665538032Speter redirecting the output channel on queue runs. It's 665638032Speter not clear this code even does anything. From Eric 665738032Speter Wassenaar of the Dutch National Institute for Nuclear 665838032Speter and High-Energy Physics. 665938032Speter Fix some problems that caused queue runs to do "too much work", 666038032Speter such as double-reading the Errors-To: header. From 666138032Speter Eric Wassenaar. 666238032Speter Error messages on writing the temporary file (including the 666338032Speter data file) were getting suppressed in SMTP -- this 666438032Speter fix causes them to be properly reported. From Eric 666538032Speter Wassenaar. 666638032Speter Some changes to support AF_UNIX sockets -- this will only 666738032Speter really become relevant in the next release, but some 666838032Speter people need it for local patches. From Michael 666938032Speter Corrigan of UC San Diego. 667038032Speter Use dynamically allocated memory (instead of static buffers) 667138032Speter for macros defined in initsys() and settime(); since 667238032Speter these can have different values depending on which 667338032Speter envelope they are in. From Eric Wassenaar. 667438032Speter Improve logging to show ctladdr on to= logging; this tells you 667538032Speter what uid/gid processes ran as. 667638032Speter Fix a problem that caused error messages to be discarded if 667738032Speter the sender address was unparseable for some reason; 667838032Speter this was supposed to fall back to the "return to 667938032Speter postmaster" case. 668038032Speter Improve aliaswait backoff algorithm. 668138032Speter Portability patches for Linux (8.6.3 required another header 668238032Speter file) (from Karl London) and SCO UNIX. 668338032Speter CONFIG: patch prog mailer to not strip host name off of envelope 668438032Speter addresses (so that it matches local again). From 668538032Speter Christopher Davis. 668638032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 668738032Speter this prevents uux from seeing lines with null names like 668838032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 668938032Speter Nakamura of Kyoto University. 669038032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 669138032Speter it shouldn't fail miserably.

It was previously listed as 670438032Speter the current time. Bug reported by Eric Hagberg of 670538032Speter Cornell University Medical College. 670638032Speter If there is an error when writing the body of a message, 670738032Speter don't send the trailing dot and wait for a response 670838032Speter in sender SMTP, as this could cause the connection to 670938032Speter hang up under some bizarre circumstances. From Eric 671038032Speter Wassenaar. 671138032Speter Fix some server SMTP synchronization problems caused when 671238032Speter connections fail during message collection. From 671338032Speter Eric Wassenaar. 671438032Speter Fix a problem that can cause srvrsmtp to reject mail if the 671538032Speter name server is down -- it accepts the RCPT but rejects 671638032Speter the DATA command. Problem reported by Jim Murray of 671738032Speter Stratus. 671838032Speter Fix a problem that can cause core dumps if the config file 671938032Speter incorrectly resolves to a null hostname. Reported by 672038032Speter Allan Johannesen of WPI. 672138032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 672238032Speter by non-root users were not put into 672338032Speter X-Authentication-Warning:s as intended because the 672443730Speter config file hadn't set the PrivacyOptions yet. Fix 672538032Speter from Sven-Ove Westberg of the University of Lulea. 672638032Speter Under very odd circumstances, the alias file rebuild code 672738032Speter could get confused as to whether a database was 672838032Speter open or not. 672938032Speter Check "vendor code" on the end of V lines -- this is 673038032Speter intended to provide a hook for vendor-specific 673138032Speter configuration syntax. (This is a "new feature", 673238032Speter but I've made an exception to my rule in a belief 673338032Speter that this is a highly exceptional case.) 673438032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 673538032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 673638032Speter (from Jon Forrest of UC Berkeley) 673738032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 673838032Speter 673964562Sgshapiro8.6.1/8.6 1993/10/08 674038032Speter Portability fixes for A/UX and Encore UMAX V. 674138032Speter Fix error message handling -- if you had a name server down 674238032Speter causing an error during parsing, that message was never 674338032Speter propagated to the queue file. 674438032Speter 674564562Sgshapiro8.6/8.6 1993/10/05 674638032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 674738032Speter conf.h (other systems have the same bug). 674838032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 674938032Speter getdtablesize() instead of sysconf(); a disturbingly 675038032Speter large number of systems defined _SC_OPEN_MAX in the 675138032Speter header files but don't have the syscall. 675238032Speter Another patch to really truly ignore MX records in getcanonname 675338032Speter if trymx == FALSE. 675438032Speter Fix problem that caused the "250 IAA25499 Message accepted for 675538032Speter delivery" message to be omitted if there was an error 675638032Speter in the header of the message (e.g., a bad Errors-To: 675738032Speter line). Pointed out by Michael Corrigan of UCSD. 675838032Speter Announce name of host we are chatting when we get errors; this 675938032Speter is an IDA-ism suggested by Christophe Wolfhugel. 676038032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 676138032Speter Australian Artificial Intelligence Institute), SCO Unix 676238032Speter (from Murray Kucherawy of Hookup Communication Corp.), 676338032Speter NeXT (from Vince DeMarco and myself), Linux (from 676438032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 676538032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 676638032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 676738032Speter Some changes to get around gcc optimizer bugs. From Takahiro 676838032Speter Kanbe. 676938032Speter Fix error recovery in queueup if another tf file of the same 677038032Speter name already exists. Problem stumbled over by Bill 677138032Speter Wisner of The Well. 677238032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 677338032Speter Problem noted by Keith McMillan of Ameritech Services. 677438032Speter Deal with group permissions properly when opening .forward and 677538032Speter :include: files. This relaxes the 8.1C restrictions 677638032Speter slightly more. This includes proper setting of groups 677738032Speter when reading :include: files, allowing you to read some 677838032Speter files that you should be able to read but have previously 677938032Speter been denied unless you owned them or they had "other" 678038032Speter read permission. 678138032Speter Make certain that $j is in $=w (after the .cf is read) so that 678238032Speter if the user is forced to override some silly system, 678338032Speter MX suppression will still work. 678438032Speter Fix a couple of efficiency problems where newstr was double- 678538032Speter calling expensive routines. In at least one case, it 678638032Speter wasn't guaranteed that they would always return the 678738032Speter same result. Problem noted by Christophe Wolfhugel. 678838032Speter Fix null pointer dereference in putoutmsg -- only on an error 678938032Speter condition from a non-SMTP mailer. From Motonori 679038032Speter Nakamura. 679138032Speter Macro expand "C" line class definitions before scanning so that 679238032Speter "CX $Z" works. 679338032Speter Fix problem that caused error message to be sent while still 679438032Speter trying to send the original message if the connection 679538032Speter is closed during a DATA command after getting an error 679638032Speter on an RCPT command (pretty obscure). Problem reported 679738032Speter by John Myers of CMU. 679838032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 679938032Speter term bug. 680038032Speter Fix a nasty bug causing core dumps when returning the "warning: 680138032Speter cannot deliver for N hours -- will keep trying" message; 680243730Speter it only occurred if you had PostmasterCopy set and 680338032Speter only on some architectures. Although sendmail would 680438032Speter keep trying, it would send error messages on each 680538032Speter queue interval. This is an important fix. 680638032Speter Allow u and g options to take user and group names respectively. 680738032Speter Don't do a chdir into the queue directory in -bt mode to make 680838032Speter ruleset testing a bit easier. 680938032Speter Don't allow users to turn off logging (using -oL) on the command 681038032Speter line -- command line can only raise, not lower, logging 681138032Speter level. 681238032Speter Set $u to the original recipient on the SMTP transaction or on 681338032Speter the command line. This is only done if there is exactly 681438032Speter one recipient. Technically, this does not meet the 681538032Speter specs, because it does not guarantee a domain on the 681638032Speter address. 681738032Speter Fix a problem that dumped error messages on bad addresses if 681838032Speter you used the -t flag. Problem noted by Josh Smith of 681938032Speter Harvey Mudd College. 682038032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 682138032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 682238032Speter avoid the problem of people who use angle brackets in 682338032Speter their full name information. 682438032Speter Fix a null pointer dereference if you set option "l", have 682538032Speter an Errors-To: header in the message, and have Errors-To: 682638032Speter defined in the config file H lines. From J.R. Oldroyd. 682738032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 682838032Speter wrong when compiling. Suggested by Rick McCarty of TI. 682938032Speter Fix a problem that could pass negative SIZE parameter if the 683038032Speter df file got lost; this would cause servers to always 683138032Speter give a temporary failure, making the problem even worse. 683238032Speter Problem noted by Allan Johannesen of WPI. 683338032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 683438032Speter protocol timeouts (30s default). Requested by Murray 683538032Speter Kucherawy of HookUp Communication Corp. to handle bogus 683638032Speter PC TCP/IP implementations. 683738032Speter Change $w default definition to be just the first component of 683838032Speter the domain name on config level 5. The $j macro defaults 683938032Speter to the FQDN; $m remains as before. This lets well-behaved 684038032Speter config files use any of the short, long, or subdomain 684138032Speter names. 684238032Speter Add makesendmail script in src to try to automate multi-architecture 684338032Speter builds. I know, this is sub-optimal, but it is still 684438032Speter helpful. 684538032Speter Fix very obscure race condition that can cause a queue run to 684638032Speter get a queue file for an already completed job. This 684738032Speter problem has existed for years. Problem noted by the 684838032Speter long suffering Allan Johannesen of WPI. 684938032Speter Fix a problem that caused the raw sender name to be passed to 685038032Speter udbsender instead of the canonified name -- this caused 685138032Speter it to sometimes miss records that it should have found. 685238032Speter Relax check of name on HELO packet so that a program using -bs 685338032Speter that claims to be itself works properly. 685438032Speter Restore rewriting of $: part of address through 2, R, 4 in 685538032Speter buildaddr -- this requires passing a lot of flags to get 685638032Speter it right. Unlike old versions, this ONLY rewrites 685738032Speter recipient addresses, not sender addresses. 685838032Speter Fix a bug that caused core dumps in config files that cannot 685938032Speter resolve /file/name style addresses. Fix from Jonathan 686038032Speter Kamens of OpenVision Technologies. 686138032Speter Fix problem with fcntl locking that can cause error returns to 686238032Speter be lost if the lock is lost; this required fully 686338032Speter queueing everything, dropping the envelope (so errors 686438032Speter would get returned), and then re-reading the queue from 686538032Speter scratch. 686638032Speter Fix a problem that caused aliases that redefine an otherwise 686738032Speter true address to still send to the original address 686838032Speter if and only if the alias failed in certain bizarre 686938032Speter ways (e.g, if they pointed at a list:; syntax address). 687038032Speter Problem pointed out by Jonathan Kamens. 687138032Speter Remove support for frozen configuration files. They caused 687238032Speter more trouble than it was worth. 687338032Speter Fix problem that can cause error messages to get ignored when 687438032Speter using both -odb and -t flags. Problem noted by Rob 687538032Speter McNicholas at U.C. Berkeley. 687638032Speter Include all "normal" variations on hostname in $=w. For example, 687738032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 687838032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 687938032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 688038032Speter the queue. 688138032Speter Reset SmtpPhase global on initial connection creation so that 688238032Speter messages don't come out with stale information. 688338032Speter Pass an "ext" argument to lockfile so that error/log messages 688438032Speter will properly reflect the true filename being locked. 688538032Speter Put all [...] address forms into $=w -- this eliminates the need 688638032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 688738032Speter Myers of CMU. 688838032Speter Fix a bug that can cause qf files to be left around even after 688938032Speter an SMTP RSET command. Problem and fix from Michael 689038032Speter Corrigan. 689143730Speter Don't send a PostmasterCopy to errors when the Precedence: is 689238032Speter negative. Error reports still go to the envelope 689338032Speter sender address. 689438032Speter Add LA_SHORT for load averages. 689538032Speter Lock sendmail.st file when posting statistics. 689638032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 689738032Speter set the size of the TCP send and receive buffers; if you 689838032Speter run over a slow slip line you may need to set these down 689938032Speter (although it would be better to fix the SLIP implementation 690038032Speter so that it's not necessary to recompile every program 690138032Speter that does bulk data transfer). 690238032Speter Allow null defaults on $( ... $) lookups. Problem reported by 690338032Speter Amir Plivatsky. 690438032Speter Diagnose crufty S and V config lines. This resulted from an 690538032Speter observation that some people were using the SITE macro 690638032Speter without the SITECONFIG macro first, which was causing 690738032Speter bogus config files that were not caught. 690838032Speter Fix makemap -f flag to turn off case folding (it was turning it 690938032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 691038032Speter Fix a problem that caused multiple error messages to be sent if 691138032Speter you used "sendmail -t -oem -odb", your system uses fcntl 691238032Speter locking, and one of the recipient addresses is unknown. 691338032Speter Reset uid earlier in include() so that recursive .forwards or 691438032Speter :include:s don't use the wrong uid. 691538032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 691638032Speter called, the code to recover the descriptor was broken. 691738032Speter This sometimes (only sometimes) caused problems with the 691838032Speter alias file. Fix from Motonori Nakamura. 691938032Speter Fix a problem that caused aliaswait to go into infinite recursion 692038032Speter if the @:@ metasymbol wasn't found in the alias file. 692138032Speter Improve error message on newaliases if database files cannot be 692238032Speter opened or if running with no database format defined. 692338032Speter Do a better estimation of the size of error messages when NoReturn 692438032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 692538032Speter Fix a problem causing the "c" option (don't connect to expensive 692638032Speter mailers) to be ignored in SMTP. Problem noted and the 692738032Speter solution suggested by Robert Elz of The University of 692838032Speter Melbourne. 692938032Speter Improve connection caching algorithm by passing "[host]" to 693038032Speter hostsignature, which strips the square brackets and 693138032Speter returns the real name. This allows mailertable entries 693238032Speter to match regular entries. 693338032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 693438032Speter feature, even if it doesn't work right. 693538032Speter Catch and log attempts to try the "wiz" command in server SMTP. 693638032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 693738032Speter Be more generous at assigning $z to the home directory -- do this 693838032Speter for programs that are specified through a .forward file. 693938032Speter Fix from Andrew Chang of Sun Microsystems. 694038032Speter Always save a fatal error message in preference to a non-fatal 694138032Speter error message so that the "subject" line of return 694238032Speter messages is the best possible. 694338032Speter CONFIG: reduce the number of quotes needed to quote configuration 694438032Speter parameters with commas: two quotes should work now, e.g., 694538032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 694638032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 694738032Speter connections (domain-ized UUCP). 694838032Speter CONFIG: fix bug in default maps (-o must be before database file 694964562Sgshapiro name). Pointed out by Christophe Wolfhugel. 695038032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 695138032Speter DNS. This would presumably be used in UUCP islands. 695238032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 695338032Speter CONFIG: log $u in Received: line. This is in technical violation 695438032Speter of the standards, since it doesn't guarantee a domain 695538032Speter on the address. 695638032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 695738032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 695838032Speter the "m" flag should you want it. Apparently some Solaris 2.2 695938032Speter installations can't handle multiple local recipients. 696038032Speter Problem noted by Josh Smith. 696138032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 696238032Speter CONFIG: change default version level from 4 to 5. 696338032Speter CONFIG: add FEATURE(nullclient) to create a config file that 696438032Speter forwards all mail to a hub without ever looking at the 696538032Speter addresses in any detail. 696638032Speter CONFIG: properly strip mailer: information off of relays when 696738032Speter used to change .BITNET form into %-hack form. 696838032Speter CONFIG: fix a problem that caused infinite loops if presented 696938032Speter with an address such as "!foo". 697038032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 697138032Speter the reverse "PTR" mapping is broken. There's a better 697238032Speter way to do this, but the change is fairly major and I 697338032Speter want to hold it for another release. Problem noted by 697438032Speter Bret Marquis. 697538032Speter 697664562Sgshapiro8.5/8.5 1993/07/23 697738032Speter Serious bug: if you used a command line recipient that was unknown 697838032Speter sendmail would not send a return message (it was treating 697938032Speter everything as though it had an SMTP-style client that 698038032Speter would do the return itself). Problem noted by Josh Smith. 698138032Speter Change "trymx" option in getcanonname() to ignore all MX data, 698238032Speter even during a T_ANY query. This actually didn't break 698338032Speter anything, because the only time you called getcanonname 698438032Speter with !trymx was if you already knew there were no MX 698538032Speter records, but it is somewhat cleaner. From Motonori 698638032Speter Nakamura. 698738032Speter Don't call getcanonname from getmxrr if you already know there 698838032Speter are no DNS records matching the name. 698938032Speter Fix a problem causing error messages to always include "The 699038032Speter original message was received ... from localhost". 699138032Speter The correct original host information is now included. 699238032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 699338032Speter version of "test" doesn't have the -x flag). Change it 699438032Speter to use -f instead. From John Myers. 699538032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 699638032Speter esmtp -- it should be smtp. 699738032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 699838032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 699938032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 700038032Speter this cleans up the configs somewhat. This fixes a serious 700138032Speter problem that caused route-addrs to get mistaken as relays, 700238032Speter pointed out by John Myers. WARNING: this also causes 700338032Speter the default on SMART_HOST to change from "suucp" to 700438032Speter "relay" if you have MAILER(smtp) specified. 700538032Speter 700664562Sgshapiro8.4/8.4 1993/07/22 700738032Speter Add option `w'. If you receive a message that comes to you because 700838032Speter you are the best (lowest preference) target of an MX, and 700938032Speter you haven't explicitly recognized the source MX host in 701038032Speter your .cf file, this option will cause you to try the target 701138032Speter host directly (as if there were no MX for it at all). If 701238032Speter `w' is not set, this case is a configuration error. 701338032Speter Beware: if `w' is set, senders may get bogus errors like 701438032Speter "message timed out" or "host unknown" for problems that 701538032Speter are really configuration errors. This option is 701638032Speter disrecommended, provided only for compatibility with 701738032Speter UIUC sendmail. 701838032Speter Fix a problem that caused the incoming socket to be left open 701938032Speter when sendmail forks after the DATA command. This caused 702038032Speter calling systems to wait in FIN_WAIT_2 state until the 702138032Speter entire list was processed and the child closed -- a 702238032Speter potentially prodigious amount of time. Problem noted 702338032Speter by Neil Rickert. 702438032Speter Fix problem (created in 6.64) that caused mail sent to multiple 702538032Speter addresses, one of which was a bad address, to completely 702638032Speter suppress the sending of the message. This changes 702738032Speter handling of EF_FATALERRS somewhat, and adds an 702838032Speter EF_GLOBALERRS flag. This also fixes a potential problem 702938032Speter with duplicate error messages if there is a syntax error 703038032Speter in the header of a message that isn't noticed until late 703138032Speter in processing. Original problem pointed out by Josh Smith 703238032Speter of Harvey Mudd College. This release includes quite a bit 703338032Speter of dickering with error handling (see below). 703438032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 703538032Speter will only hurt already-broken software and should help 703638032Speter humans. 703738032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 703838032Speter compiled in. It would never read the alias file. 703938032Speter Repair unbalanced `)' and `>' (the "open" versions are already 704038032Speter repaired). 704138032Speter Logging of "done" in dropenvelope() was incorrect: it would 704238032Speter log this even when the queue file still existed. Change 704338032Speter this to only log "done" (at log level 11) when the 704438032Speter queue file is actually removed. From John Myers. 704538032Speter Log "lost connection" in server SMTP at log level 20 if there 704638032Speter is no pending transaction. Some senders just close the 704738032Speter connection rather than sending QUIT. 704838032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 704938032Speter domains that do not have MX records -- this would cause 705038032Speter the subsequent host name lookup to fail. The problem 705138032Speter only occurred if you had FEATURE(nocanonify) set. 705238032Speter Problem noted by Rick McCarty of Texas Instruments. 705338032Speter Fix invocation of setvbuf when passed a -X flag -- I had 705438032Speter unwittingly used an ANSI C extension, and this caused 705538032Speter core dumps on some machines. 705638032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 705738032Speter Previously it just gave an empty send queue, which 705838032Speter then gave either "Need RCPT (recipient)" at the DATA 705938032Speter (confusing, since you had given an RCPT command which 706038032Speter returned 250) or just dropped the email, depending on 706138032Speter whether you were running VERBose mode. Now it usually 706238032Speter diagnoses this case as "aliasing/forwarding loop broken". 706338032Speter Unfortunately, it still doesn't adequately diagnose 706438032Speter some true error conditions. 706538032Speter Add internal concept of "warning messages" using 6xx codes. 706638032Speter These are not reported only to Postmaster. Unbalanced 706738032Speter parens, brackets, and quotes are printed as 653 codes. 706838032Speter They are always mapped to 5xx codes before use in SMTP. 706938032Speter Clean up error messages to tell both the actual address that 707038032Speter failed and the alias they arose from. This makes it 707138032Speter somewhat easier to diagnose problems. Difficulty noted 707238032Speter by Motonori Nakamura. 707338032Speter Fix a problem that inappropriately added a ctladdr to addresses 707438032Speter that shouldn't have had one during a queue run. This 707538032Speter caused error messages to be handled differently during 707638032Speter a queue run than a direct run. 707738032Speter Don't print the qf name and line number if you get errors during 707838032Speter the direct run of the queue from srvrsmtp -- this was 707938032Speter just extra stuff for users to crawl through. 708038032Speter Put command line flags on second line of pid file so you can 708138032Speter auto-restart the daemon with all appropriate arguments. 708238032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 708338032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 708438032Speter restart it. 708538032Speter Remove the ``setuid(getuid())'' in main -- this caused the 708638032Speter IDENT daemon to screw up. This required that I change 708738032Speter HASSETEUID to HASSETREUID and complicate the mode 708838032Speter changing somewhat because both Ultrix and SunOS seem 708938032Speter to have a bug causing seteuid() to set the saved uid 709038032Speter as well as the effective. The program test/t_setreuid.c 709138032Speter will test to see if your implementation of setreuid(2) 709238032Speter is appropriately functional. 709338032Speter The FallBackMX (option V) handling failed to properly identify 709438032Speter fallback to yourself -- most of the code was there, 709538032Speter but it wasn't being enabled. Problem noted by Murray 709638032Speter Kucherawy of the University of Waterloo. 709738032Speter Change :include: open timeout from ETIMEDOUT to an internal 709838032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 709938032Speter with CurHostName" in error messages, which can be 710038032Speter confusing. Reported by Jonathan Kamens of OpenVision 710138032Speter Technologies. 710238032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 710338032Speter process group id. The original fix was to get around 710438032Speter some problems with recalcitrant MUAs, but it breaks 710538032Speter any call from a shell that creates a process group id 710638032Speter different from the process id. I could try to fix 710738032Speter this by diddling the tty owner (using tcsetpgrp or 710838032Speter equivalent) but this is too likely to break other 710938032Speter things. 711038032Speter Portability changes: 711138032Speter Support -M as equivalent to -oM on Ultrix -- apparently 711238032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 711338032Speter instead of using standard flags. Oh joy. This 711443730Speter behavior reported by Jon Giltner of University 711538032Speter of Colorado. 711638032Speter SGI IRIX -- this includes several changes that should 711738032Speter help other strict ANSI compilers. 711838032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 711938032Speter Corporation. 712038032Speter Solaris running the Sun C compiler (which despite the 712138032Speter documentation apparently doesn't define 712238032Speter __STDC__ by default). 712338032Speter ConvexOS from Eric Schnoebelen of Convex. 712438032Speter Sony NEWS workstations and Omron LUNA workstations from 712538032Speter Motonori Nakamura. 712638032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 712738032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 712838032Speter several people have made a good argument that this 712938032Speter creates more problems than it solves (although this 713038032Speter may prove painful in the short run). 713138032Speter CONFIG: generalize all the relays to accept a "mailer:host" 713238032Speter format. 713338032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 713438032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 713538032Speter addresses are also passed through this ruleset. 713638032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 713738032Speter internet-style addresses would "fall off the end" of 713838032Speter ruleset zero and be interpreted as local -- however, 713938032Speter the angle brackets confused the recursive call. 714038032Speter These are now diagnosed as "Unrecognized host name". 714138032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 714238032Speter ifdef(`_MAILER_USENET_') instead of 714338032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 714438032Speter of SINTEF RUNIT, Oslo. 714538032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 714638032Speter early in ruleset 0; this allows .mc authors to bypass 714738032Speter things like the "short circuit" code for local addresses. 714838032Speter Prompted by a comment by Bill Wisner of The Well. 714938032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 715038032Speter esmtp) to send SMTP mail. This allows you to default 715138032Speter to esmtp but use a mailertable or other override to 715238032Speter deal with broken servers. This logic was pointed out 715338032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 715438032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 715538032Speter environments. Ugly as sin. 715638032Speter 715764562Sgshapiro8.3/8.3 1993/07/13 715838032Speter Fix setuid problems introduced in 8.2 that caused messages 715938032Speter like "Cannot create qfXXXXXX: Invalid argument" 716038032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 716138032Speter involved a new compile flag "HASSETEUID" that takes 716238032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 716338032Speter that the POSIX interface is broken enough to break 716438032Speter some systems badly. This includes some fixes for 716538032Speter HP-UX. Also fixes problems where the real uid is 716638032Speter not reset properly on startup (from Neil Rickert). 716738032Speter Fix a problem that caused timed out messages to not report the 716838032Speter addresses that timed out. Error messages are also more 716938032Speter "user friendly". 717038032Speter Drop required bandwidth on connections from 64 bytes/sec to 717138032Speter 16 bytes/sec. 717238032Speter Further Solaris portability changes -- doesn't require the BSD 717338032Speter compatibility library. This also adds a new 717438032Speter "HASGETDTABLESIZE" compile flag which can be used if 717538032Speter you want to use getdtablesize(2) instead of sysconf(2). 717638032Speter These are loosely based on changes from David Meyer at 717738032Speter University of Oregon. This now seems to work, at least 717838032Speter for quick test cases. 717938032Speter Fix a problem that can cause duplicate error messages to be 718038032Speter sent if you are in SMTP, you send to multiple addresses, 718138032Speter and at least one of those addresses is good and points 718238032Speter to an account that has a .forward file (whew!). 718338032Speter Fix a problem causing messages to be discarded if checkcompat() 718438032Speter returned EX_TEMPFAIL (because it didn't properly mark 718538032Speter the "to" address). Problem noted by John Myers. 718638032Speter Fix dfopen to return NULL if the open failed; I was depending 718738032Speter on fdopen(-1) returning NULL, which isn't the case. This 718838032Speter isn't serious, but does result in weird error diagnoses. 718938032Speter From Michael Corrigan. 719038032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 719138032Speter messages sent through UUCP-family mailers. Suggested 719238032Speter by Bill Wisner of The Well. 719338032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 719438032Speter include a "uucp-dom" mailer that uses domain-style 719538032Speter addressing. Suggested by Bill Wisner. 719638032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 719738032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 719838032Speter Christophe Wolfhugel. 719938032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 720038032Speter 720164562Sgshapiro8.2/8.2 1993/07/11 720238032Speter Don't drop out on config file parse errors in -bt mode. 720338032Speter On older configuration files, assume option "l" (use Errors-To 720438032Speter header) for back compatibility. NOTE: this DOES NOT 720538032Speter imply an endorsement of the Errors-To: header in any way. 720638032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 720738032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 720838032Speter SMTP server to give an error on this command, and 720938032Speter logging it in the transcript can be confusing. Fix 721038032Speter from Bill Wisner. 721138032Speter IRIX compatibility changes provided by Dan Rich 721238032Speter <drich@sandman.lerc.nasa.gov>. 721338032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 721438032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 721538032Speter <juo@klinzhai.rutgers.edu> 721638032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 721738032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 721838032Speter match the other flags in that file. 721938032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 722038032Speter Save h_errno in mci struct and improve error message display. 722138032Speter Changes from Eric Wassenaar. 722238032Speter Open /dev/null for the transcript if the create of the xf file 722338032Speter failed; this avoids at least one possible null pointer 722438032Speter reference in very weird cases. From Eric Wassenaar. 722538032Speter Clean up statistics gathering; it was over-reporting because of 722638032Speter forks. From Eric Wassenaar. 722738032Speter Fix problem that causes old Return-Path: line to override new 722838032Speter Return-Path: line (conf.c needs H_FORCE to avoid 722938032Speter re-using old value). From Motonori Nakamura. 723038032Speter Fix broken -m flag in K definition -- even if -m (match only) 723138032Speter was specified, it would still replace the key with the 723238032Speter value. Noted by Rick McCarty of Texas Instruments. 723338032Speter If the name server timed out over several days, no "timed out" 723438032Speter message would ever be sent back. The timeout code 723538032Speter has been moved from markfailure() to dropenvelope() 723638032Speter so that all such failures should be diagnosed. Pointed 723738032Speter out by Christophe Wolfhugel and others. 723838032Speter Relax safefile() constraints: directories in an include or 723938032Speter forward path must be readable by self if the controlling 724038032Speter user owns the entry, readable by all otherwise (e.g., 724138032Speter when reading your .forward file, you have to own and 724238032Speter have X permission in it; everyone needs X permission in 724338032Speter the root and directories leading up to your home); 724438032Speter include files must be readable by anyone, but need not 724538032Speter be owned by you. 724638032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 724738032Speter reading a .forward file; this gets around some problems 724838032Speter on NFS mounts if root permission is not exported and 724938032Speter the user's home directory isn't x'able. 725038032Speter Additional NeXT portability enhancements from Axel Zinser. 725138032Speter Additional HP-UX portability enhancements from Brian Bullen. 725238032Speter Add a timeout around SMTP message writes; this assumes you can 725338032Speter get throughput of at least 64 bytes/second. Note that 725438032Speter this does not impact the "datafinal" default, which 725538032Speter is separate; this is just intended to work around 725638032Speter network clogs that will occur before the final dot 725738032Speter is sent. From Eric Wassenaar. 725838032Speter Change map code to set the "include null" flag adaptively -- 725938032Speter it initially tries both, but if it finds anything 726038032Speter matching without a null it never tries again with a 726138032Speter null and vice versa. If -N is specified, it never 726238032Speter tries without the null and creates new maps with a 726338032Speter null byte. If -O is specified, it never tries with 726438032Speter the null (for efficiency). If -N and -O are specified, 726538032Speter you get -NO (get it?) lookup at all, so this would 726638032Speter be a bad idea. If you don't specify either -N or -O, 726738032Speter it adapts. 726838032Speter Fix recognition of "same from address" so that MH submissions 726938032Speter will insert the appropriate full name information; 727038032Speter this used to work and got broken somewhere along the 727138032Speter way. 727238032Speter Some changes to eliminate some unnecessary SYSERRs in the 727338032Speter log. For example, if you lost a connection, don't 727438032Speter bother reporting that fact on the connection you lost. 727538032Speter Add some "extended debugging" flags to try to track down 727638032Speter why we get occasional problems with file descriptor 727738032Speter one being closed when execing a mailer; it seems to 727838032Speter only happen when there has been another error in the 727938032Speter same transaction. This requires XDEBUG, defined 728038032Speter by default in conf.h. 728138032Speter Add "-X filename" command line flag, which logs both sides of 728238032Speter all SMTP transactions. This is intended ONLY for 728338032Speter debugging bad implementations of other mailers; start 728438032Speter it up, send a message from a mailer that is failing, 728538032Speter and then kill it off and examine the indicated log. 728638032Speter This output is not intended to be particularly human 728738032Speter readable. This also adds the HASSETVBUF compile 728838032Speter flag, defaulted on if your compiler defines __STDC__. 728938032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 729038032Speter have a local net that should get direct connects, you 729138032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 729238032Speter See cf/README for an example. 729338032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 729438032Speter sites that don't use the -d flag. 729538032Speter CONFIG: hide recipient addresses as well as sender addresses 729638032Speter behind $M if FEATURE(allmasquerade) is specified; this 729738032Speter has been requested by several people, but can break 729838032Speter local aliases. For example, if you mail to "localalias" 729938032Speter this will be rewritten as "localalias@masqueradehost"; 730038032Speter although initial delivery will work, replies will be 730138032Speter broken. Use it sparingly. 730238032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 730338032Speter to qualified domains in headers. I believe this is 730438032Speter largely equivalent to the IDA feature of the same name. 730538032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 730638032Speter to override the "system name" as your UUCP name -- 730738032Speter in particular, to use domain-ized UUCP names. From 730838032Speter Bill Wisner of The Well. 730938032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 731038032Speter first. This is currently unused in the config files, 731138032Speter but could be used in a mailertable entry. 731238032Speter 731364562Sgshapiro8.1C/8.1B 1993/06/27 731438032Speter Serious security bug fix: it was possible to read any file on 731538032Speter the system, regardless of ownership and permissions. 731638032Speter If a subroutine returns a fully qualified address, return it 731738032Speter immediately instead of feeding it back into rewriting. 731838032Speter This fixes a problem with mailertable lookups. 731938032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 732038032Speter 732164562Sgshapiro8.1B/8.1A 1993/06/12 732238032Speter Serious bug fix: pattern matching backup algorithm stepped by 732338032Speter two tokens in classes instead of one. Found by Claus 732438032Speter Assmann at University of Kiel, Germany. 732538032Speter 732664562Sgshapiro8.1A/8.1A 1993/06/08 732738032Speter Another mailertable fix.... 732838032Speter 732964562Sgshapiro8.1/8.1 1993/06/07 733038032Speter 4.4BSD freeze.
