Additionally make sure that 13161389Sgshapiro an internal variable is set properly to avoid those 14161389Sgshapiro misleading errors. Based on patch from Steve Hubert 15161389Sgshapiro of University of Washington. 16161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 17161389Sgshapiro the process that forks the daemon exited, i.e., if 18161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 19161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 20161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 21161389Sgshapiro David F. Skoll. 22161389Sgshapiro Avoid a crash when finishing due to referencing a freed variable. 23161389Sgshapiro Problem reported and diagnosed by Moritz Jodeit. 24161389Sgshapiro CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4 25161389Sgshapiro range (0..255). 26161389Sgshapiro LIBMILTER: The "hostname" argument of the xxfi_connect() callback 27161389Sgshapiro previously was the equivalent of {client_ptr}. However, 28161389Sgshapiro this did not match the documentation of the function, hence 29161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 30161389Sgshapiro about these macros. 31161389Sgshapiro 32159609Sgshapiro8.13.7/8.13.7 2006/06/14 33159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 34159609Sgshapiro crash while trying to send a mail due to a stack overflow, 35159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 36159609Sgshapiro happens because the recursion of the function mime8to7() 37159609Sgshapiro was not restricted. The function is called for MIME 8 to 38159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 39159609Sgshapiro To work around this problem, recursive calls are limited to 40159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 41159609Sgshapiro limit is treated as opaque and is not checked further. 42159609Sgshapiro Problem noted by Frank Sheiness. 43159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 44159609Sgshapiro SASL mechanisms that use the security layer, e.g., 45159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 46159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 47159609Sgshapiro a df file might have been left behind in the queue. 48159609Sgshapiro This was another side effect of the changes to the I/O 49159609Sgshapiro layer made in 8.13.6. 50159609Sgshapiro Several minor problems have been fixed that were found by a 51159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 52159609Sgshapiro distribution. See http://scan.coverity.com/ 53159609Sgshapiro Note: the scan generated also a lot of "false positives", 54159609Sgshapiro e.g., "error" reports about situations that cannot happen. 55159609Sgshapiro Most of those code places are marked with lint(1) comments 56159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 57159609Sgshapiro Hence an explicit assertion has been added in some cases 58159609Sgshapiro to avoid those false positives. 59159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 60159609Sgshapiro error then in some cases shared memory segments or pid 61159609Sgshapiro files were not removed. 62159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 63159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 64159609Sgshapiro reported by Akihiro Sagawa. 65159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 66159609Sgshapiro bug work-around. Hence if sendmail is linked against 67159609Sgshapiro either of these versions and compression is available, 68159609Sgshapiro the padding bug work-around is turned off. Based on 69159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 70159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 71159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 72159609Sgshapiro however, that list is no longer available. To avoid 73159609Sgshapiro further problems, no default value is available anymore, 74159609Sgshapiro but an argument must be specified. 75159609Sgshapiro Portability: 76159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c. Patch from 77159609Sgshapiro Pieter Bowman of the University of Utah. 78159609Sgshapiro 79157001Sgshapiro8.13.6/8.13.6 2006/03/22 80157001Sgshapiro SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server 81157001Sgshapiro and client side of sendmail with timeouts in the libsm I/O 82157001Sgshapiro layer and fix problems in that code. Also fix handling of 83157001Sgshapiro a buffer in sm_syslog() which could have been used as an 84157001Sgshapiro attack vector to exploit the unsafe handling of 85157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 86157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 87157001Sgshapiro Handle theoretical integer overflows that could triggered if 88157001Sgshapiro the server accepted headers larger than the maximum 89157001Sgshapiro (signed) integer value. This is prevented in the default 90157001Sgshapiro configuration by restricting the size of a header, and on 91157001Sgshapiro most machines memory allocations would fail before reaching 92157001Sgshapiro those values. Problems found by Phil Brass of ISS. 93157001Sgshapiro If a server returns 421 for an RSET command when trying to start 94157001Sgshapiro another transaction in a session while sending mail, do 95157001Sgshapiro not trigger an internal consistency check. Problem found 96157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 97157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 98157001Sgshapiro to a STARTTLS command despite the fact that it advertised 99157001Sgshapiro STARTTLS and that the code is not valid according to RFC 100157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 101157001Sgshapiro of a protocol error (which has been changed to a 102157001Sgshapiro temporary error in 8.13.5). Problem reported by Jeff 103157001Sgshapiro A. Earickson of Colby College. 104157001Sgshapiro Clear SMTP state after a HELO/EHLO command. Patch from John 105157001Sgshapiro Myers of Proofpoint. 106157001Sgshapiro Observe MinQueueAge option when gathering entries from the queue 107157001Sgshapiro for sorting etc instead of waiting until the entries are 108157001Sgshapiro processed. Patch from Brian Fundakowski Feldman. 109157001Sgshapiro Set up TLS session cache to properly handle clients that try to 110157001Sgshapiro resume a stored TLS session. 111157001Sgshapiro Properly count the number of (direct) child processes such that 112157001Sgshapiro a configured value (MaxDaemonChildren) is not exceeded. 113157001Sgshapiro Based on patch from Attila Bruncsak. 114157001Sgshapiro LIBMILTER: Remove superfluous backslash in macro definition 115157001Sgshapiro (libmilter.h). Based on patch from Mike Kupfer of 116157001Sgshapiro Sun Microsystems. 117157001Sgshapiro LIBMILTER: Don't try to set SO_REUSEADDR on UNIX domain sockets. 118157001Sgshapiro This generates an error message from libmilter on 119157001Sgshapiro Solaris, though other systems appear to just discard the 120157001Sgshapiro request silently. 121157001Sgshapiro LIBMILTER: Deal with sigwait(2) implementations that return 122157001Sgshapiro -1 and set errno instead of returning an error code 123157001Sgshapiro directly. Patch from Chris Adams of HiWAAY Informations 124157001Sgshapiro Services. 125157001Sgshapiro Portability: 126157001Sgshapiro Fix compilation checks for closefrom(3) and statvfs(2) 127157001Sgshapiro in NetBSD. Problem noted by S. Moonesamy, patch from 128157001Sgshapiro Andrew Brown. 129157001Sgshapiro 130157001Sgshapiro8.13.5/8.13.5 2005/09/16 131157001Sgshapiro Store the filesystem identifier of the df/ subdirectory (if it 132157001Sgshapiro exists) in an internal structure instead of the base 133157001Sgshapiro directory. This structure is used decide whether there 134157001Sgshapiro is enough free disk space when selecting a queue, hence 135157001Sgshapiro without this change queue selection could fail if a df/ 136157001Sgshapiro subdirectory exists and is on a different filesystem 137157001Sgshapiro than the base directory. 138157001Sgshapiro Use the queue index of the df file (instead of the qf file) for 139157001Sgshapiro checking whether a link(2) operation can be used to split 140157001Sgshapiro an envelope across queue groups. Problem found by 141157001Sgshapiro Werner Wiethege. 142157001Sgshapiro If the list of items in the queue is larger than the maximum 143157001Sgshapiro number of items to process, sort the queue first and 144157001Sgshapiro then cut the list off instead of the other way around. 145157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 146157001Sgshapiro Fix helpfile to show full entry for ETRN. Problem noted by 147157001Sgshapiro Penelope Fudd, patch from Neil Rickert of Northern Illinois 148157001Sgshapiro University. 149157001Sgshapiro FallbackSmartHost should also be tried on temporary errors. 150157001Sgshapiro From John Beck of Sun Microsystems. 151157001Sgshapiro When a server responds with 421 to the STARTTLS command then treat 152157001Sgshapiro it as a temporary error, not as protocol error. Problem 153157001Sgshapiro noted by Andrey J. Melnikoff. 154157001Sgshapiro Properly define two functions in libsm as static because their 155157001Sgshapiro prototype used static too. Patch from Peter Klein. 156157001Sgshapiro Fix syntax errors in helpfile for MAIL and RCPT commands. 157157001Sgshapiro LIBMILTER: When smfi_replacebody() is called with bodylen equals 158157001Sgshapiro zero then do not silently ignore that call. Patch from 159157001Sgshapiro Gurusamy Sarathy of Active State. 160157001Sgshapiro LIBMILTER: Recognize "421" also in a multi-line reply to terminate 161157001Sgshapiro the SMTP session with that error. Fix from Brian Kantor. 162157001Sgshapiro Portability: New option HASSNPRINTF which can be set if the OS 163157001Sgshapiro has a properly working snprintf(3) to get rid 164157001Sgshapiro of the last two (safe) sprintf(3) calls in the 165157001Sgshapiro source code. 166157001Sgshapiro Add support for AIX 5.3. 167157001Sgshapiro Add support for SunOS 5.11 (aka Solaris 11). 168157001Sgshapiro Add support for Darwin 8.x. Patch from Lyndon Nerenberg. 169157001Sgshapiro OpenBSD 3.7 has removed support for NETISO. 170157001Sgshapiro CONFIG: Add OSTYPE(freebsd6) for FreeBSD 6.X. 171157001Sgshapiro Set DontBlameSendmail to AssumeSafeChown and 172157001Sgshapiro GroupWritableDirPathSafe for OSTYPE(darwin). 173157001Sgshapiro Patch from Lyndon Nerenberg. 174157001Sgshapiro Some features still used 4.7.1 as enhanced status code which 175157001Sgshapiro was supposed to be eliminated in 8.13.0 because some 176157001Sgshapiro broken systems misinterpret it as a permanent error. 177157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 178157001Sgshapiro Some default values in a generated cf file did not match 179157001Sgshapiro the defaults in the sendmail binary. Problem noted 180157001Sgshapiro by Mike Pechkin. 181157001Sgshapiro New Files: 182157001Sgshapiro cf/ostype/freebsd6.m4 183157001Sgshapiro devtools/OS/AIX.5.3 184157001Sgshapiro devtools/OS/Darwin.8.x 185157001Sgshapiro devtools/OS/SunOS.5.11 186157001Sgshapiro include/sm/time.h 187157001Sgshapiro 188147078Sgshapiro8.13.4/8.13.4 2005/03/27 189147078Sgshapiro The bug fixes in 8.13.3 for connection handling uncovered a 190147078Sgshapiro different error which could result in connections that 191147078Sgshapiro stay in CLOSE_WAIT state due to a variable that was not 192147078Sgshapiro properly initialized. Problem noted by Michael Sims. 193147078Sgshapiro Deal with empty hostnames in hostsignature(). This bug could lead 194147078Sgshapiro to an endless loop when doing LMTP deliveries to another 195147078Sgshapiro host. Problem first reported by Martin Lathoud and 196147078Sgshapiro tracked down by Gael Roualland. 197147078Sgshapiro Make sure return parameters are initialized in getmxrr(). Problem 198147078Sgshapiro found by Gael Roualland using valgrind. 199147078Sgshapiro If shared memory is used and the RunAsUser option is set, then the 200161389Sgshapiro owner and group of the shared memory segment is set to 201147078Sgshapiro the ids specified RunAsUser and the access mode is set 202147078Sgshapiro to 0660 to allow for updates by sendmail processes. 203147078Sgshapiro The number of queue entries that is (optionally) kept in shared 204147078Sgshapiro memory was wrong in some cases, e.g., envelope splitting 205147078Sgshapiro and bounce generation. 206147078Sgshapiro Undo a change made in 8.13.0 to silently truncate long strings 207147078Sgshapiro in address rewriting because the message can be triggered 208147078Sgshapiro for header checks where long strings are legitimate. 209147078Sgshapiro Problem reported by Mary Verge DeSisto, and tracked 210147078Sgshapiro down with the help of John Beck of Sun Microsystems. 211147078Sgshapiro The internal stab map did not obey the -m flag. Patch from 212147078Sgshapiro Rob McMahon of Warwick University, England. 213147078Sgshapiro The socket map did not obey the -f flag. Problem noted by 214147078Sgshapiro Dan Ringdahl, forwarded by Andrzej Filip. 215147078Sgshapiro The addition of LDAP recursion in 8.13.0 broke enforcement of 216147078Sgshapiro the LDAP map -1 argument which tells the MTA to only 217147078Sgshapiro return success if and only if a single LDAP match is found. 218147078Sgshapiro Add additional error checks in the MTA for milter communication 219147078Sgshapiro to avoid a possible segmentation fault. Based on patch 220147078Sgshapiro by Joe Maimon. 221147078Sgshapiro Do not trigger an assertion if X509_digest() returns success but 222147078Sgshapiro does not assign a value to its output parameter. Based 223147078Sgshapiro on patch by Brian Kantor. 224147078Sgshapiro Add more checks when resetting internal AUTH data (applies only 225147078Sgshapiro to Cyrus SASL version 2). Otherwise an SMTP session might 226147078Sgshapiro be dropped after an AUTH failure. 227147078Sgshapiro Portability: 228147078Sgshapiro Add LA_LONGLONG as valid LA_TYPE type for systems that use 229147078Sgshapiro "long long" to read load average data, e.g., 230147078Sgshapiro AIX 5.1 in 32 bit mode. Note: this has to be set 231147078Sgshapiro "by hand", it is not (yet) automatically detected. 232147078Sgshapiro Problem noted by Burak Bilen. 233147078Sgshapiro Use socklen_t for accept(), etc. on AIX 5.x. This should 234147078Sgshapiro fix problems when compiling in 64 bit mode. 235147078Sgshapiro Problem first reported by Harry Meiert of 236147078Sgshapiro University of Bremen. 237147078Sgshapiro New Files: 238147078Sgshapiro include/sm/sem.h 239147078Sgshapiro libsm/sem.c 240147078Sgshapiro libsm/t-sem.c 241147078Sgshapiro 242141858Sgshapiro8.13.3/8.13.3 2005/01/11 243141858Sgshapiro Enhance handling of I/O errors, especially EOF, when STARTTLS 244141858Sgshapiro is active. 245141858Sgshapiro Make sure a connection is not reused after it has been closed 246141858Sgshapiro due to a 421 error. Problem found by Allan E Johannesen 247141858Sgshapiro of Worcester Polytechnic Institute. 248141858Sgshapiro Avoid triggering an assertion when sendmail is interrupted while 249141858Sgshapiro closing a connection. Problem found by Allan E Johannesen 250141858Sgshapiro of Worcester Polytechnic Institute. 251141858Sgshapiro Regression: a change in 8.13.2 caused sendmail not to try the 252141858Sgshapiro next MX host (or FallbackMXhost if configured) when, at 253141858Sgshapiro connection open, the current server returns a 4xy or 5xy 254141858Sgshapiro SMTP reply code. Problem noted by Mark Tranchant. 255141858Sgshapiro 256141858Sgshapiro8.13.2/8.13.2 2004/12/15 257141858Sgshapiro Do not split the first header even if it exceeds the internal 258141858Sgshapiro buffer size. Previously a part of such a header would 259141858Sgshapiro end up in the body of the message. Problem noted by 260141858Sgshapiro Simple Nomad of BindView. 261141858Sgshapiro Do not complain about "cataddr: string too long" when checking 262141858Sgshapiro headers that do not contain RFC 2822 addresses. 263141858Sgshapiro Problem noted by Rich Graves of Brandeis University. 264141858Sgshapiro If a server returns a 421 reply to the RSET command between 265141858Sgshapiro message deliveries, do not attempt to deliver any more 266141858Sgshapiro messages on that connection. This prevents bogus "Bad 267141858Sgshapiro file number" recipient status. Problem noted by 268141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 269141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 270141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 271141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 272141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 273141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 274141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 275141858Sgshapiro them off at a comma. Problem noted by Krzysztof Oledzki. 276141858Sgshapiro Add more logging to milter change header functions to 277141858Sgshapiro complement existing logging. Based on patch from 278141858Sgshapiro Gurusamy Sarathy of Active State. 279141858Sgshapiro Include <lber.h> in include/sm/config.h when LDAPMAP is defined. 280141858Sgshapiro Patch from Edgar Hoch of the University of Stuttgart. 281141858Sgshapiro Fix DNS lookup if IPv6 is enabled when converting an IP address 282141858Sgshapiro to a hostname for use with SASL. Problem noted by Ken Jones; 283141858Sgshapiro patch from Hajimu UMEMOTO. 284141858Sgshapiro CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog 285141858Sgshapiro mailer. Patch from John Beck of Sun Microsystems. 286141858Sgshapiro LIBMILTER: It was possible that xxfi_abort() was called after 287141858Sgshapiro xxfi_eom() for a message if some timeouts were triggered. 288141858Sgshapiro Patch from Alexey Kravchuk. 289141858Sgshapiro LIBMILTER: Slightly rearrange mutex use in listener.c to allow 290141858Sgshapiro different threads to call smfi_opensocket() and smfi_main(). 291141858Sgshapiro Patch from Jordan Ritter of Cloudmark. 292141858Sgshapiro MAIL.LOCAL: Properly terminate MBDB before exiting. Problem 293141858Sgshapiro noted by Nelson Fung. 294141858Sgshapiro MAIL.LOCAL: make strip-mail.local used a wrong path to access 295141858Sgshapiro mail.local. Problem noted by William Park. 296141858Sgshapiro VACATION: Properly terminate MBDB before exiting. Problem noted 297141858Sgshapiro by Nelson Fung. 298141858Sgshapiro Portability: 299141858Sgshapiro Add support for DragonFly BSD. 300141858Sgshapiro New Files: 301141858Sgshapiro cf/ostype/dragonfly.m4 302141858Sgshapiro devtools/OS/DragonFly 303141858Sgshapiro include/sm/os/sm_os_dragonfly.h 304141858Sgshapiro Deleted Files: 305141858Sgshapiro libsm/vsscanf.c 306141858Sgshapiro 307132943Sgshapiro8.13.1/8.13.1 2004/07/30 308132943Sgshapiro Using the default AliasFile ldap: specification would cause the 309132943Sgshapiro objectClasses of the LDAP response to be included in the 310132943Sgshapiro alias expansion. Problem noted by Brenden Conte of 311132943Sgshapiro Rensselaer Polytechnic Institute. 312132943Sgshapiro Fix support for a fallback smart host for system where DNS is 313132943Sgshapiro (partially) available. From John Beck of Sun Microsystems. 314132943Sgshapiro Fix SuperSafe=PostMilter behavior when a milter replaces a body 315132943Sgshapiro but the data file is not yet stored on disk because it is 316132943Sgshapiro smaller than the size of the memory buffer. Problem noted 317132943Sgshapiro by David Russell. 318132943Sgshapiro Fix certificate revocation list support; if a CRL was specified 319132943Sgshapiro but the other side presented a cert that was signed by 320132943Sgshapiro a different (trusted) CA than the one which issued the CRL, 321132943Sgshapiro verification would always fail. Problem noted by Al Smith. 322132943Sgshapiro Run mailer programs as the RunAsUser when RunAsUser is set and 323132943Sgshapiro the F=S mailer flag is set without a U= mailer equate. 324132943Sgshapiro Problem noted by John Gardiner Myers of Proofpoint. 325132943Sgshapiro ${nbadrcpts} was off by one if BadRcptThrottle is zero. 326132943Sgshapiro Patch from Sung-hoon Choi of DreamWiz Inc. 327132943Sgshapiro CONFIG: Emit a warning if FEATURE(`access_db') is used after 328132943Sgshapiro FEATURE(`greet_pause') because then the latter will not 329132943Sgshapiro use the access map. Note: if no default value is given 330132943Sgshapiro for FEATURE(`greet_pause') then it issues an error if 331132943Sgshapiro FEATURE(`access_db') is not specified before it. 332132943Sgshapiro Problem noted by Alexander Dalloz of University of 333132943Sgshapiro Bielefeld. 334132943Sgshapiro CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause') 335132943Sgshapiro is used to give more flexibility for local changes. 336132943Sgshapiro Portability: 337132943Sgshapiro Fix a 64 bit problem in the socket map code. Problem 338132943Sgshapiro noted by Geoff Adams. 339132943Sgshapiro NetBSD 2.0F has closefrom(3). Patch from Andrew Brown. 340132943Sgshapiro NetBSD can use sysctl(3) to get the number of CPUs in 341132943Sgshapiro a system. Patch from Andrew Brown. 342132943Sgshapiro Add a README file in doc/op/ to explain potential 343132943Sgshapiro incompatibilities with various *roff related 344132943Sgshapiro tools. Problem tracked down by Per Hedeland. 345132943Sgshapiro New Files: 346132943Sgshapiro doc/op/README 347132943Sgshapiro 348132943Sgshapiro8.13.0/8.13.0 2004/06/20 349132943Sgshapiro Do not include AUTH data in a bounce to avoid leaking confidential 350132943Sgshapiro information. See also cf/README about MSP and the section 351132943Sgshapiro "Providing SMTP AUTH Data when sendmail acts as Client". 352132943Sgshapiro Problem noted by Neil Rickert of Northern Illinois 353132943Sgshapiro University. 354132943Sgshapiro Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n 355132943Sgshapiro and -DSM_CONF_SETITIMER=0. Problem noted by Juergen Georgi 356132943Sgshapiro of RUS University of Stuttgart. 357132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 358132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 359132943Sgshapiro Add support for LDAP recursion based on types given to attribute 360132943Sgshapiro specifications in an LDAP map definition. This allows 361132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 362132943Sgshapiro URL which will in turn be queried. See the ``LDAP 363132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 364132943Sgshapiro Based on patch from Andrew Baucom. 365132943Sgshapiro Extend the default LDAP specifications for AliasFile 366132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 367132943Sgshapiro include support for LDAP recursion via new attributes. 368132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 369132943Sgshapiro of cf/README for more information. 370132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 371132943Sgshapiro LDAP API/protocol version to use. The default depends on 372132943Sgshapiro the LDAP library. 373132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 374132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 375132943Sgshapiro and -p port. This also allows for the use of LDAP over 376132943Sgshapiro SSL and connections via named sockets if your LDAP 377132943Sgshapiro library supports it. 378132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 379132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 380132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 381132943Sgshapiro during a SMTP session then terminate it just like it is 382132943Sgshapiro done for too many bad SMTP commands. 383132943Sgshapiro Basic connection rate control support has been added: the daemon 384132943Sgshapiro maintains the number of incoming connections per client 385132943Sgshapiro IP address and total in the macros {client_rate} and 386132943Sgshapiro {total_rate}, respectively. These macros can be used 387132943Sgshapiro in the cf file to impose connection rate limits. 388132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 389132943Sgshapiro determines the length of the interval for which the 390132943Sgshapiro number of connections is stored. Based on patch from 391132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 392132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 393132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 394132943Sgshapiro If enabled by the new ruleset greet_pause (see 395132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 396132943Sgshapiro amount of time before sending the initial 220 SMTP 397132943Sgshapiro greeting. If any traffic is received before then, a 554 398132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 399132943Sgshapiro during that connection. 400132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 401132943Sgshapiro server could sleep for a very long time. Fix based on 402132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 403132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 404132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 405132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 406132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 407132943Sgshapiro misinterpret it as a permanent error. 408132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 409132943Sgshapiro all milters accepted the mail. This can increase 410132943Sgshapiro performance if many mails are rejected by milters due to 411132943Sgshapiro body scans. Based on patch from David F. Skoll. 412132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 413132943Sgshapiro header, whether provided by the client or generated by 414132943Sgshapiro sendmail. 415132943Sgshapiro New macro {client_connections} which contains the number of open 416132943Sgshapiro connections in the SMTP server for the client IP address. 417132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 418132943Sgshapiro Mines de Paris. 419132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 420132943Sgshapiro to prevent confusion caused by running sendmail stop 421132943Sgshapiro scripts two or more times, where the second and subsequent 422141858Sgshapiro runs would report misleading error messages about sendmail's 423132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 424132943Sgshapiro for a discussion of the implications of this, including 425132943Sgshapiro how to correct broken scripts which may have depended on 426132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 427132943Sgshapiro Support per-daemon input filter lists which override the default 428132943Sgshapiro filter list specified in InputMailFilters. The filters 429132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 430132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 431132943Sgshapiro your configuration relies on this behavior, you have to 432132943Sgshapiro add those names to class 'w' yourself. Problem noted 433132943Sgshapiro by Sander Eerkes. 434132943Sgshapiro Support message quarantining in the mail queue. Quarantined 435132943Sgshapiro messages are not run on normal queue displays or runs 436132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 437132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 438132943Sgshapiro The -q command line option now can specify which queue to display 439132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 440132943Sgshapiro operates on lost queue items. 441132943Sgshapiro Restricted mail queue runs and displays can be done based on the 442132943Sgshapiro quarantined reason using -qQtext to run or display 443132943Sgshapiro quarantined items if the quarantine reason contains the 444132943Sgshapiro given text. Similarly, -q!Qtext will run or display 445132943Sgshapiro quarantined items which do not have the given text in the 446132943Sgshapiro quarantine reason. 447132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 448132943Sgshapiro new -Q option. See doc/op/op.me for more information. 449132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 450132943Sgshapiro quarantine reason is shown in a new line prefixed by 451132943Sgshapiro "QUARANTINE:". 452132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 453132943Sgshapiro to quarantine messages in check_* (except check_compat) and 454132943Sgshapiro header check rulesets. The $: of the mailer triplet will 455132943Sgshapiro be used for the quarantine reason. 456132943Sgshapiro Add a new quarantine count to the mailstats collected. 457132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 458132943Sgshapiro message if it is quarantined. 459132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 460132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 461132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 462132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 463132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 464132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 465132943Sgshapiro lookup for the client IP address. Note: this is the same 466132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 467132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 468132943Sgshapiro recipients received so far in a transaction. 469132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 470132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 471132943Sgshapiro noted by Kai Schlichting. 472132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 473132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 474132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 475132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 476132943Sgshapiro Wolfhugel of France Telecom Oleane. 477132943Sgshapiro Do not silently truncate long strings in address rewriting. 478132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 479132943Sgshapiro Oceana Matrix Ltd. 480132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 481132943Sgshapiro support mutual authentication. From Kenneth Murchison of 482132943Sgshapiro Oceana Matrix Ltd. 483132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 484132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 485132943Sgshapiro format just like the STARTTLS related macros to avoid 486132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 487132943Sgshapiro Masarati of SysNet s.n.c. 488132943Sgshapiro New option AuthRealm to set the authentication realm that is 489132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 490132943Sgshapiro of the University of Manitoba. 491132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 492132943Sgshapiro successful, otherwise relaying would be allowed if 493132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 494132943Sgshapiro is active. 495132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 496132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 497132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 498132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 499132943Sgshapiro DIGEST-MD5 and LOGIN. 500132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 501132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 502132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 503132943Sgshapiro overwrite each other's pid files. 504132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 505132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 506132943Sgshapiro Wolfhugel of France Telecom. 507132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 508132943Sgshapiro LogLevel 12 or higher. 509132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 510132943Sgshapiro try to use the SMTP command VERB to propagate this option 511132943Sgshapiro to the MTA which in turn will show the delivery just like 512132943Sgshapiro it was done before the default 8.12 separation of MSP and 513132943Sgshapiro MTA. Based on patch by Per Hedeland. 514132943Sgshapiro If a daemon is refusing connections for longer than the time specified 515132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 516132943Sgshapiro to high load, log this information. Patch from John Beck 517132943Sgshapiro of Sun Microsystems. 518132943Sgshapiro Remove the ability for non-trusted users to raise the value of 519132943Sgshapiro CheckpointInterval on the command line. 520132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 521132943Sgshapiro subset of the functionality of the 's' flag. 522132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 523132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 524132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 525132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 526132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 527132943Sgshapiro causing subsequent messages to be sent instead of being 528132943Sgshapiro discarded. This also caused milter callbacks to be called 529132943Sgshapiro out of order after the SMTP session was reset. 530132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 531132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 532132943Sgshapiro further information. 533132943Sgshapiro New command line option -D logfile to send debug output to 534132943Sgshapiro the indicated log file instead of stdout. 535132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 536132943Sgshapiro queue return and warning times for delivery status 537132943Sgshapiro notifications. 538132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 539132943Sgshapiro at all. 540132943Sgshapiro Several more return values for ruleset srv_features have been added 541132943Sgshapiro to enable/disable certain features in the server per 542132943Sgshapiro connection. See doc/op/op.me for details. 543132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 544132943Sgshapiro for DaemonPortOptions. 545132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 546132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 547132943Sgshapiro of Northern Illinois University. 548132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 549132943Sgshapiro be tried as a last resort after all other fallbacks. This 550132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 551132943Sgshapiro view of inside the company, but an incomplete view of 552132943Sgshapiro outside). From John Beck of Sun Microsystems. 553132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 554132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 555132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 556132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 557132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 558132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 559132943Sgshapiro of the University of Illinois at Urbana-Champaign. 560132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 561132943Sgshapiro applications for use in the xxfi_eom() callback. 562132943Sgshapiro New macro {time} which contains the output of the time(3) function, 563132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 564132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 565132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 566132943Sgshapiro terminate the SMTP session with a 421 error message. 567132943Sgshapiro Get rid of dead code that tried to access the environment variable 568132943Sgshapiro HOSTALIASES. 569132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 570132943Sgshapiro compile with -DUSE_TTYPATH=1. 571132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 572132943Sgshapiro the header value passed in without balancing quotes, 573132943Sgshapiro parentheses, and angle brackets. Based on patch from 574132943Sgshapiro Oleg Bulyzhin. 575132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 576132943Sgshapiro angle brackets when reading in rulesets. This allows 577132943Sgshapiro rules to be written for header checks to catch strings 578132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 579132943Sgshapiro Based on patch from Oleg Bulyzhin. 580132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 581132943Sgshapiro some temporary errors like ECONNABORTED. 582132943Sgshapiro Added list of CA certificates that are used by members of the 583132943Sgshapiro sendmail consortium, see CACerts. 584132943Sgshapiro Portability: 585132943Sgshapiro Two new compile options have been added: 586132943Sgshapiro HASCLOSEFROM System has closefrom(3). 587132943Sgshapiro HASFDWALK System has fdwalk(3). 588132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 589132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 590132943Sgshapiro change to using fcntl() locking until they can fix 591132943Sgshapiro it. Be sure to update other sendmail related 592132943Sgshapiro programs to match locking techniques. 593132943Sgshapiro New compile time option NEEDINTERRNO which should be set 594132943Sgshapiro if <errno.h> does not declare errno itself. 595132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 596132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 597132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 598132943Sgshapiro Center for Scientific Computing. 599132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 600132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 601132943Sgshapiro Remove path from compiler definition for Interix because 602132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 603132943Sgshapiro Also use <sys/mkdev.h> to get the correct 604132943Sgshapiro major()/minor() definitions.

Cannot resolve PTR 1124102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1125102528Sgshapiro modification causes a change of behavior if an IP net/address 1126102528Sgshapiro is listed in the access map with REJECT and a host/domain 1127102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1128102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1129102528Sgshapiro change was made on request of Neil Rickert of Northern 1130102528Sgshapiro Illinois University, the side effect has been found by 1131102528Sgshapiro Stefaan Van Hoornick. 1132102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1133102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1134102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1135102528Sgshapiro University. 1136102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1137102528Sgshapiro Fix from Andrzej Filip. 1138102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1139102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1140102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1141102528Sgshapiro NULL pointer.

In previous versions this could cause mail 127894334Sgshapiro not to be delivered if a queue file is repeatedly moved 127994334Sgshapiro by an external process whenever sendmail moved it back 128094334Sgshapiro into the right place. Some precautions have been taken 128194334Sgshapiro to avoid moving queue files if not really necessary. 128294334Sgshapiro sendmail may use links to refer to queue files and it 128394334Sgshapiro may store the path of data files in queue files. Hence 128494334Sgshapiro queue files should not be moved unless those internals 128594334Sgshapiro are understood and the integrity of the files is not 128694334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 128794334Sgshapiro University. 128894334Sgshapiro If an error mail is created, and the mail is split across different 128994334Sgshapiro queue directories, and SuperSafe is off, then write the mail 129094334Sgshapiro to disk before splitting it, otherwise an assertion is 129194334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 129294334Sgshapiro of INTERMETA. 129394334Sgshapiro Fix possible race condition that could cause sendmail to forget 129494334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 129594334Sgshapiro Handle bogus qf files better without triggering assertions. 129694334Sgshapiro Problem noted by Guy Feltin. 129794334Sgshapiro Protect against interrupted select() call when enforcing Milter 129894334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 129994334Sgshapiro ActiveState. 130094334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 130194334Sgshapiro noted by Anne Bennett of Concordia University. 130294334Sgshapiro If privileges have been dropped, don't try to change group ID to 130394334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 130494334Sgshapiro Northern Illinois University. 130594334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 130694334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 130794334Sgshapiro of Dinoex. 130894334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 130994334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 131094334Sgshapiro Polytechnic Institute. 131194334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 131294334Sgshapiro if several mails are sent in one session and some of them 131394334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 131494334Sgshapiro Change timeout check such that cached information about a connection 131594334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 131694334Sgshapiro Based on patch from David Burns of Portland State University. 131794334Sgshapiro Properly count message size for mailstats during mail collection. 131894334Sgshapiro Problem noted by Werner Wiethege. 131994334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 132094334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 132194334Sgshapiro Provide workaround for getopt() implementations that do not catch 132294334Sgshapiro missing arguments. 132394334Sgshapiro Fix the message size calculation if the message body is replaced by 132494334Sgshapiro a milter filter and buffered file I/O is being used. 132594334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 132694334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 132794334Sgshapiro Problem noted by Werner Wiethege. 132894334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 132994334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 133094334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 133194334Sgshapiro Properly deal with a case where sendmail is called by root running 133294334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 133394334Sgshapiro Lusky of ISS Atlanta. 133494334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 133594334Sgshapiro directories are used and mail is sent to a mailing list 133694334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 133794334Sgshapiro of Concordia University. 133894334Sgshapiro Fix class map parsing code if optional key is specified. Problem 133994334Sgshapiro found by Mario Nigrovic. 134094334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 134194334Sgshapiro incoming messages. A leading dot is always stripped by the 134294334Sgshapiro SMTP receiver regardless of whether or not it is followed by 134394334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 134494334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 134594334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 134694334Sgshapiro Elvers. 134794334Sgshapiro Correct the statistics gathered for total number of connections. 134894334Sgshapiro Instead of being the exact same number as the total number 134994334Sgshapiro of messages (T line in mailstats) it now represents the 135094334Sgshapiro total number of TCP connections. 135194334Sgshapiro Be more explicit about syntax errors in addresses, especially 135294334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 135394334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 135494334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 135594334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 135694334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 135794334Sgshapiro Problem noted by Fletcher Mattox of the University of 135894334Sgshapiro Texas. 135994334Sgshapiro Change the SMTP error code for temporary map failures from 421 136094334Sgshapiro to 451. 136194334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 136294334Sgshapiro only done in one place: queue group creation). Based on 136394334Sgshapiro patch by Bryan Costales. 136494334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 136594334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 136694334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 136794334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 136894334Sgshapiro errors. By doing so, the host was marked as having a 136994334Sgshapiro temporary problem and other mail destined for that host was 137094334Sgshapiro queued for the next queue run. Problem noted by Fletcher 137194334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 137294334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 137394334Sgshapiro and Neil Rickert of Northern Illinois University. 137494334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 137594334Sgshapiro which drop the connection instead of responding to the 137694334Sgshapiro command). 137794334Sgshapiro Portability: 137894334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 137998121Sgshapiro available. 138094334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 138194334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 138294334Sgshapiro settings. Patch from Elias Halldor Agustsson of 138394334Sgshapiro Skyrr. 138494334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 138594334Sgshapiro noted by John Beck. 138694334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 138794334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 138894334Sgshapiro Rajesh Somasund of Hewlett-Packard. 138994334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 139094334Sgshapiro SMTP AUTH information. This feature was actually added in 139194334Sgshapiro 8.12.0 but a release note was not included. 139294334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 139394334Sgshapiro parameter is set and the LDAP lookup returns a temporary 139494334Sgshapiro error. 139594334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 139694334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 139794334Sgshapiro Krzysztof Oledzki. 139894334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 139994334Sgshapiro initialization as aliases are not needed for the MSP. 140094334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 140194334Sgshapiro is in use. Patch from Andrzej Filip. 140294334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 140394334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 140494334Sgshapiro This will only have an effect if a parameter is specified, 140594334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 140694334Sgshapiro it is embedded in square brackets. Problem noted by 140794334Sgshapiro Theo Van Dinter of Collective Technologies. 140894334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 140994334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 141094334Sgshapiro to allow for the proper time zone on systems where the 141194334Sgshapiro default results in misleading time stamps. That is, syslog 141294334Sgshapiro time stamps and Date headers on submitted mail will use the 141394334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 141494334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 141594334Sgshapiro by Neil Rickert of Northern Illinois University. 141694334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 141794334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 141894334Sgshapiro noted by John Beck. 141994334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 142094334Sgshapiro if queue groups are used. 142194334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 142294334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 142394334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 142494334Sgshapiro Suggested by Bryan Costales. 142594334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 142694334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 142794334Sgshapiro structure that is passed to xxfi_connect(). Notice: 142898121Sgshapiro this fix requires that sendmail and libmilter both have 142998121Sgshapiro this change; mixing versions may lead to wrong port 143094334Sgshapiro values depending on the endianness of the involved systems. 143194334Sgshapiro Problem noted by Gisle Aas of ActiveState. 143294334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 143394334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 143494334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 143594334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 143694334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 143794334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 143894334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 143994334Sgshapiro this to 1 if your LDAP client libraries include 144094334Sgshapiro ldap_memfree(). 144194334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 144294334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 144394334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 144494334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 144594334Sgshapiro VACATION: Allow root to operate on user vacation databases.

Colburn of the New Mexico 146890792Sgshapiro Institute of Mining and Technology. 146990792Sgshapiro Only log milter body replacements once instead of for each body 147090792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 147190792Sgshapiro the Finnish Meteorological Institute. 147290792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 147390792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 147490792Sgshapiro of the Finnish Meteorological Institute. 147590792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 147690792Sgshapiro needs to collect children status to avoid zombie processes. 147790792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 147890792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 147990792Sgshapiro commands are issued. This makes it consistent with normal 148090792Sgshapiro SMTP connections. 148190792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 148290792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 148390792Sgshapiro and Technology. 148490792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 148590792Sgshapiro message sender if the sender had used a deprecated RFC822 148690792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 148790792Sgshapiro Meteorological Institute. 148890792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 148990792Sgshapiro parsing.

Patch from David Powell 151190792Sgshapiro of Sun Microsystems. 151290792Sgshapiro Allow specification of an empty realm via the authinfo ruleset. 151390792Sgshapiro This is necessary to interoperate as an SMTP AUTH client 151490792Sgshapiro with servers that do not support realms when using 151590792Sgshapiro CRAM-MD5. Problem noted by Bjoern Voigt of TU Berlin. 151690792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 151790792Sgshapiro server gets stuck while processing that command. Problem 151890792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 151990792Sgshapiro In addition to printing errors when parsing recipients during 152090792Sgshapiro command line invocations log them to make it simpler 152190792Sgshapiro to understand possible DSNs to postmaster. 152290792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 152390792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 152490792Sgshapiro instead of forcing localhost. 152590792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 152690792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 152790792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 152890792Sgshapiro noted by Neil Rickert of Northern Illinois University. 152990792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 153090792Sgshapiro dropping the connection during an SMTP transaction, stop 153190792Sgshapiro sending commands. This prevents bogus "Bad file number" 153290792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 153390792Sgshapiro Worcester Polytechnic Institute. 153490792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 153590792Sgshapiro almost always too small; do not guess the size at all. 153690792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 153790792Sgshapiro Compaq Computer Corp. 153890792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 153990792Sgshapiro properly.

Add configuration options for 161390792Sgshapiro different set*gid() calls to reset saved gid. Problem 161490792Sgshapiro found by Michal Zalewski. 161590792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 161690792Sgshapiro privileges by disabling debugging (command line -d flag) 161790792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 161890792Sgshapiro used. Suggested by Michal Zalewski. 161990792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 162090792Sgshapiro Problem found by Michal Zalewski. 162190792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 162290792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 162390792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 162490792Sgshapiro If debugging is turned on (-d0.10) print not just the default 162590792Sgshapiro values for configuration file and pid file but also the 162690792Sgshapiro selected values. Problem noted by Brad Chapman. 162790792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 162890792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 162990792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 163090792Sgshapiro this only applied to hostname canonification. Problem 163190792Sgshapiro noted by Bill Fenner of AT&T Research. 163290792Sgshapiro Ignore comments in NIS host records when trying to find the 163390792Sgshapiro canonical name for a host. 163490792Sgshapiro When sendmail has extra privileges, limit mail submission command 163590792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 163690792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 163790792Sgshapiro suggestion from Michal Zalewski. 163890792Sgshapiro Portability: 163990792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 164090792Sgshapiro `uname` does not given complete information. 164190792Sgshapiro Problem noted by Keith Neufeld of the Cessna 164290792Sgshapiro Aircraft Company. 164390792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 164490792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 164590792Sgshapiro Avoid compiler warnings by not using pointers to pass 164690792Sgshapiro integers.

You need to create a new user and 167990792Sgshapiro a new group before installing sendmail (both called smmsp by 168090792Sgshapiro default). The installation process tries to install 168190792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 168290792Sgshapiro default.

Suggested 169390792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 169490792Sgshapiro (IdS). 169590792Sgshapiro Fixed problem of a global variable being used for a timeout jump 169690792Sgshapiro point where the variable could become overused for more than 169790792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 169890792Sgshapiro a corrupted stack causing a core dump. The timeout is now 169990792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 170090792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 170190792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 170290792Sgshapiro checks (group ID of RunAsUser). This allows use of a 170390792Sgshapiro set-group-ID sendmail binary for initial message submission 170490792Sgshapiro and no set-user-ID root sendmail is needed. For details 170590792Sgshapiro see sendmail/SECURITY. 170690792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 170790792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 170890792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 170990792Sgshapiro with a fallback of sendmail.cf as configuration file. See 171090792Sgshapiro sendmail/SECURITY. 171190792Sgshapiro New configuration file option UseMSP to allow group writable queue 171290792Sgshapiro files if the group is the same as that of a set-group-ID 171390792Sgshapiro sendmail binary. See sendmail/SECURITY. 171490792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 171590792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 171690792Sgshapiro is sendmail.cf (to be backward compatible). This selection 171790792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 171890792Sgshapiro file: client or mta). See sendmail/SECURITY. 171990792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 172090792Sgshapiro command has been removed. 172190792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 172290792Sgshapiro at compile time or per host (ruleset). 172390792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 172490792Sgshapiro used to look up local mail recipients; the default value 172590792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 172690792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 172790792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 172890792Sgshapiro long, to accomodate envelope splitting. File systems with 172990792Sgshapiro a 14 character file name length limit are no longer 173090792Sgshapiro supported. 173190792Sgshapiro Recipient list used for delivery now gets internally ordered by 173290792Sgshapiro hostsignature (character string version of MX RR). This orders 173390792Sgshapiro recipients for the same MX RR's together meaning smaller 173490792Sgshapiro portions of the list need to be scanned (instead of the whole 173590792Sgshapiro list) each delivery() pass to determine piggybacking. The 173690792Sgshapiro significance of the change is better the larger the recipient 173790792Sgshapiro list. Hostsignature is now created during recipient list 173890792Sgshapiro creation rather than just before delivery. 173990792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 174090792Sgshapiro piggybacking (called coincidental) extended to coattail 174190792Sgshapiro piggybacking. Rather than complete MX RR matching 174290792Sgshapiro (coincidental) piggybacking is done if just the lowest value 174390792Sgshapiro preference matches (coattail). 174490792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 174590792Sgshapiro try other MX hosts if available. 174690792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 174790792Sgshapiro outgoing (client-side) SMTP Authentication. 174890792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 174990792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 175090792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 175190792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 175290792Sgshapiro A new ruleset authinfo can be used to return client side 175390792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 175490792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 175590792Sgshapiro removed in future versions. 175690792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 175790792Sgshapiro requires 334. Mercury 1.48 is a known offender. 175890792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 175990792Sgshapiro for the security layer in SMTP AUTH (SASL). See 176090792Sgshapiro doc/op/op.me for details. 176190792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 176290792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 176390792Sgshapiro signed the presented certificate, the CN and the MD5 hash 176490792Sgshapiro of the presented certificate, respectively. 176590792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 176690792Sgshapiro New ruleset srv_features to enable/disable certain features in the 176790792Sgshapiro server per connection. See doc/op/op.me for details. 176890792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 176990792Sgshapiro recipient; useful to decide whether a conection is secure 177090792Sgshapiro enough on a per recipient basis. 177190792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 177290792Sgshapiro for STARTTLS. 177390792Sgshapiro If no certificate has been requested, the macro {verify} has the 177490792Sgshapiro value "NOT". 177590792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 177690792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 177790792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 177890792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 177990792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 178090792Sgshapiro really required. This change results in a noticable 178190792Sgshapiro performance gains on most machines. Moreover, if shared 178290792Sgshapiro memory is in use, reuse the key several times. 178390792Sgshapiro Add queue groups which can be used to group queue directories with 178490792Sgshapiro the same behavior together. See doc/op/op.me for details. 178590792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 178690792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 178790792Sgshapiro are initially sorted which may result in faster envelope 178890792Sgshapiro splitting. If the mail is submitted directly from the 178990792Sgshapiro command line, then the value also limits the number of 179090792Sgshapiro processes to deliver the envelopes; if more envelopes are 179190792Sgshapiro created they are only queued up and must be taken care of 179290792Sgshapiro by a queue run. 179390792Sgshapiro The check for 'enough disk space' now pays attention to which file 179490792Sgshapiro system each queue directory resides in. 179590792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 179690792Sgshapiro New option QueueFileMode for the default permissions of queue files. 179790792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 179890792Sgshapiro group (one or more queues in a multi-queue environment 179990792Sgshapiro collected together) to process the same work list at the 180090792Sgshapiro same time. 180190792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 180290792Sgshapiro active queue runner processes. 180390792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 180490792Sgshapiro runners per queue group. 180590792Sgshapiro Queue member selection by substring pattern matching now allows 180690792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 180790792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 180890792Sgshapiro of the queue that match during processing. 180990792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 181090792Sgshapiro periodically forking a child to process the queue, a single 181190792Sgshapiro child is forked for each queue that sleeps between queue 181290792Sgshapiro runs. A SIGHUP signal can be sent to restart this 181390792Sgshapiro persistent queue runner. 181490792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 181590792Sgshapiro sendmail process which only runs the queue at an interval: 181690792Sgshapiro sendmail -q15m). 181790792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 181890792Sgshapiro Proposed by Thom O'Connor. 181990792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 182090792Sgshapiro unless the new -qf option or -v is used. 182190792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 182290792Sgshapiro several queue runners are started by hand to avoid contention. 182390792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 182490792Sgshapiro of the qf file (older entries first). 182590792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 182690792Sgshapiro a client to specify an amount of time within which an e-mail 182790792Sgshapiro should be delivered. New option DeliverByMin added to set the 182890792Sgshapiro minimum amount of time or disable the extension. 182990792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 183090792Sgshapiro not allowed unless escaped or quoted. 183190792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 183290792Sgshapiro by Leif Johansson of Stockholm University, which was based on 183390792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 183490792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 183590792Sgshapiro Technology, Stockholm, Sweden. 183690792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 183790792Sgshapiro behavior (no MX lookups), put the name in square brackets. 183890792Sgshapiro Proposed by Thom O'Connor. 183990792Sgshapiro Use shared memory to store free space of filesystems that are used 184090792Sgshapiro for queues, if shared memory is available and if a key is set 184190792Sgshapiro via SharedMemoryKey. This minimizes the number of system 184290792Sgshapiro calls to check the available space. See doc/op/op.me for 184390792Sgshapiro details. 184490792Sgshapiro If shared memory is compiled in the option -bP can be used to print 184590792Sgshapiro the number of entries in the queue(s). 184690792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 184790792Sgshapiro and the usual documentation for details. 184890792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 184990792Sgshapiro Remove '-U' (initial user submission) command line option as 185090792Sgshapiro announced in 8.10. 185190792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 185290792Sgshapiro New macro {addr_type} which contains whether the current address is 185390792Sgshapiro an envelope sender or recipient address. Suggested by 185490792Sgshapiro Neil Rickert of Northern Illinois University. 185590792Sgshapiro Two new options for host maps: -d (retransmission timeout), 185690792Sgshapiro -r (number of retries). 185790792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 185890792Sgshapiro separator such that a lookup can return both an attribute 185990792Sgshapiro and value separated by the given separator. 186090792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 186190792Sgshapiro to map class arith. 186290792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 186390792Sgshapiro (errors that occur when sending an error message) are dropped. 186490792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 186590792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 186690792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 186790792Sgshapiro requirements for files containing secret keys. This is 186890792Sgshapiro necessary for the MSP if client authentification is used. 186990792Sgshapiro Properly handle quoted filenames for class files (to allow for 187090792Sgshapiro filenames with spaces). 187190792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 187290792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 187390792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 187490792Sgshapiro {if_addr_out} address of interface of outgoing connection. 187590792Sgshapiro {if_family_out} family of interface of outgoing connection. 187690792Sgshapiro The latter two are only set if the interface does not belong 187790792Sgshapiro to the loopback net. 187890792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 187990792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 188090792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 188190792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 188290792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 188390792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 188490792Sgshapiro all connections for a single delivery attempt to succeed. 188590792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 188690792Sgshapiro a threshold number of recipients has been rejected (option 188790792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 188890792Sgshapiro Development Group. 188990792Sgshapiro New option DelayLA to delay connections if the load averages 189090792Sgshapiro exceeds the specified value. The default of 0 does not 189190792Sgshapiro change the previous behavior. A value greater than 0 189290792Sgshapiro will cause sendmail to sleep for one second on most 189390792Sgshapiro SMTP commands and before accepting connections if that 189490792Sgshapiro load average is exceeded. 189590792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 189690792Sgshapiro recipients that are sent during a connection to a mailer. 189790792Sgshapiro This also introduces a new mailer field 'r' which defines 189890792Sgshapiro the maximum number of recipients (defaults to 100). 189990792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 190090792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 190190792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 190290792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 190390792Sgshapiro instead. 190490792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 190590792Sgshapiro builtin mailer pathnames. Use TCP instead. 190690792Sgshapiro PH map code updated to use the new libphclient API instead of the 190790792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 190890792Sgshapiro University of Illinois at Urbana-Champaign. 190990792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 191090792Sgshapiro for direct (command line) submissions. 191190792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 191290792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 191390792Sgshapiro Hagino of the KAME Project. 191490792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 191590792Sgshapiro whose content is rewritten similar to Reply-To:. 191690792Sgshapiro Proposed by Andrzej Filip. 191790792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 191890792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 191990792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 192090792Sgshapiro AUTH/STARTTLS related logfile entries. 192190792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 192290792Sgshapiro before logging. 192390792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 192490792Sgshapiro (at LogLevel 9/10 or higher). 192590792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 192690792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 192790792Sgshapiro in which most commands are rejected due to check_relay or 192890792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 192990792Sgshapiro Change logging format for cloned envelopes to be similar to that for 193090792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 193190792Sgshapiro of the Universitat Regensburg. 193290792Sgshapiro Added libsm, a C library of general purpose abstractions including 193390792Sgshapiro assertions, tracing and debugging with named debug categories, 193490792Sgshapiro exception handling, malloc debugging, resource pools, 193590792Sgshapiro portability abstractions, and an extensible buffered I/O 193690792Sgshapiro package. It will at some point replace libsmutil. 193790792Sgshapiro See libsm/index.html for details. 193890792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 193990792Sgshapiro care of by fork() and exit(). 194090792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 194190792Sgshapiro more consistent portablity amongst different platforms 194290792Sgshapiro new and old (from new libsm). 194390792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 194490792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 194590792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 194690792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 194790792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 194890792Sgshapiro synchronizations calls. 194990792Sgshapiro Add per-recipient status information to mailq -v output. 195090792Sgshapiro T_ANY queries are no longer used by sendmail. 195190792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 195290792Sgshapiro too (see include/sm/cdefs.h for more info). 195390792Sgshapiro sendmail -d now has general support for named debug categories. 195490792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 195590792Sgshapiro for details. 195690792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 195790792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 195890792Sgshapiro generated by this condition were illegal (not RFC conform). 195990792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 196090792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 196190792Sgshapiro mailer and the recipient has hence been rejected during the 196290792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 196390792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 196490792Sgshapiro that do not have postmaster defined. If an email was sent 196590792Sgshapiro from an address to which a DSN cannot be returned and 196690792Sgshapiro in which at least one recipient address is non-deliverable, 196790792Sgshapiro then that email had been delivered in each queue run. 196890792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 196990792Sgshapiro degli Studi dell'Insubria. 197090792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 197190792Sgshapiro i.e., the corresponding code is always compiled in now. 197290792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 197390792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 197490792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 197590792Sgshapiro attempting to canonify a hostname, some broken nameservers 197690792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 197790792Sgshapiro lookups. If you want to excuse this behavior, use this new 197890792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 197990792Sgshapiro Mark Roth of the University of Illinois at 198090792Sgshapiro Urbana-Champaign. 198190792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 198290792Sgshapiro noted by Joy Latten of IBM. 198390792Sgshapiro ConnectionRateThrottle limits the number of connections per second 198490792Sgshapiro to each daemon individually, not the overall number of 198590792Sgshapiro connections. 198690792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 198790792Sgshapiro sendmail to use a default alias schema as outlined in the 198890792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 198990792Sgshapiro cf/README. 199090792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 199190792Sgshapiro the first character after the class name is not a '/' or a 199290792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 199390792Sgshapiro rest of the line will be parsed as a map lookup. This 199490792Sgshapiro allows classes to be filled via a map lookup. See op.me 199590792Sgshapiro for more syntax information. Specifically, this can be 199690792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 199790792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 199890792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 199990792Sgshapiro example). 200090792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 200190792Sgshapiro the default schema used in the above two items. 200290792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 200390792Sgshapiro warning if a program being run from a mailer or file class 200490792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 200590792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 200690792Sgshapiro if a program being run from a mailer or file class 200790792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 200890792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 200990792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 201090792Sgshapiro (without quotes) will disable this and return to the 201190792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 201290792Sgshapiro Suggested by Bryan Stansell of GNAC. 201390792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 201490792Sgshapiro HELO/EHLO commands. 201590792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 201690792Sgshapiro possible protocol family which may be used for outgoing 201790792Sgshapiro connections. Restrictions placed on one family only affect 201890792Sgshapiro outgoing connections on that particular family. Because of 201990792Sgshapiro this change, the ${client_flags} macro is not set until the 202090792Sgshapiro connection is established. Based on patch from Motonori 202190792Sgshapiro Nakamura of Kyoto University. 202290792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 202390792Sgshapiro when the -bv option is given by users who are neither root 202490792Sgshapiro nor the TrustedUser so users can not read private aliases, 202590792Sgshapiro forwards, or :include: files. It also will override the -v 202690792Sgshapiro (verbose) command line option. 202790792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 202890792Sgshapiro address can't be used for the outgoing connection, fall 202990792Sgshapiro back to the settings in ClientPortOptions (if set). 203090792Sgshapiro Problem noted by John Beck of Sun Microsystems. 203190792Sgshapiro New named config file rule check_data for DATA command (input: 203290792Sgshapiro number of recipients). Based on patch from Mark Roth of 203390792Sgshapiro the University of Illinois at Urbana-Champaign. 203490792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 203590792Sgshapiro can be specified using the '#' option character. For 203690792Sgshapiro example, 'ETRN #queuegroup'. 203790792Sgshapiro If an LDAP server times out or becomes unavailable, close the 203890792Sgshapiro current connection and reopen to get to one of the fallback 203990792Sgshapiro servers. Patch from Paul Hilchey of the University of 204090792Sgshapiro British Columbia. 204190792Sgshapiro Make default error number on $#error messages 550 instead of 501 204290792Sgshapiro because 501 is not allowed on all commands. 204390792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 204490792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 204590792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 204690792Sgshapiro if required. 204790792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 204890792Sgshapiro class instead. 204990792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 205090792Sgshapiro "IPv6:" tag to identify the address properly. For example, 205190792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 205290792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 205390792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 205490792Sgshapiro MTA is running. For example, during a queue run. 205590792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 205690792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 205790792Sgshapiro Nelson of IBM. 205890792Sgshapiro The maximum number of commands before the MTA slows down when too 205990792Sgshapiro many "light weight" commands have been received are now 206090792Sgshapiro configurable during compile time. The current values and 206190792Sgshapiro their defaults are: 206290792Sgshapiro MAXBADCOMMANDS 25 unknown commands 206390792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 206490792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 206590792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 206690792Sgshapiro MAXETRNCOMMANDS 8 ETRN 206790792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 206890792Sgshapiro Costales of SL3D, Inc. 206990792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 207090792Sgshapiro ${MyMacro} is defined but also that it is not empty. 207190792Sgshapiro Properly quote usernames with special characters if they are used 207290792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 207390792Sgshapiro Meteorological Institute. 207490792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 207590792Sgshapiro messages for messages for mailing list expanded addresses 207690792Sgshapiro which are not delivered on the initial attempt. 207790792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 207890792Sgshapiro the final dot has been sent to avoid affecting future 207990792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 208090792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 208190792Sgshapiro file systems that require to call fsync() for a directory 208290792Sgshapiro if the meta-data in it has been changed. This should be 208390792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 208490792Sgshapiro See sendmail/README for further information. 208590792Sgshapiro Avoid file locking deadlock when updating the statistics file if 208690792Sgshapiro sendmail is signaled to terminate. Problem noted by 208790792Sgshapiro Christophe Wolfhugel of France Telecom. 208890792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 208990792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 209090792Sgshapiro the Finnish Meteorological Institute. 209190792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 209290792Sgshapiro from Peter A. Friend of EarthLink. 209390792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 209490792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 209590792Sgshapiro flora.ca. 209690792Sgshapiro Portability: 209790792Sgshapiro Remove support for AIX 2, which supports only 14 character 209890792Sgshapiro filenames and is outdated anyway. Suggested by 209990792Sgshapiro Valdis Kletnieks of Virginia Tech. 210090792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 210190792Sgshapiro i.e., use default /usr/sbin, change owner/group 210290792Sgshapiro of man pages and user-executable to root/sys, set 210390792Sgshapiro optimization limit to 0 (unlimited). Based on patch 210490792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 210590792Sgshapiro Hurtta of the Finnish Meteorological Institute. 210690792Sgshapiro Do not assume LDAP support is installed by default under 210790792Sgshapiro Solaris 8 and later. 210890792Sgshapiro Add support for OpenUNIX. 210990792Sgshapiro CONFIG: Increment version number of config file to 10. 211090792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 211190792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 211290792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 211390792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 211490792Sgshapiro temporary lookup failures. 211590792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 211690792Sgshapiro action to be taken by aborting the search for domain names 211790792Sgshapiro or IP nets. 211890792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 211990792Sgshapiro relay address as long as the other part allows the email 212090792Sgshapiro to get through. 212190792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 212290792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 212390792Sgshapiro entry like user+*@domain. This allows handling of details by 212490792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 212590792Sgshapiro introduced to match only non-empty details of addresses. 212690792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 212790792Sgshapiro and hence there is no required order within the MAILER 212890792Sgshapiro section anymore except for MAILER(`uucp') which must come 212990792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 213090792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 213190792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 213290792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 213390792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 213490792Sgshapiro in the access map which returns OK or RELAY actually 213590792Sgshapiro terminates check_* ruleset checking. 213690792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 213790792Sgshapiro tls_rcpt, see cf/README for details. 213890792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 213990792Sgshapiro STARTTLS has been used to "(version=${tls_version} 214090792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 214190792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 214290792Sgshapiro options friends/haters instead of "To:" and enable 214390792Sgshapiro specification of whole domains instead of just users. 214490792Sgshapiro Notice: this change is not backward compatible. 214590792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 214690792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 214790792Sgshapiro cf/README for details. 214890792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 214990792Sgshapiro the access map.

Gumpertz of Computer Problem 215990792Sgshapiro Solving. 216090792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 216190792Sgshapiro options, see doc/op/op.me for details. 216290792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 216390792Sgshapiro the security layer in SMTP AUTH (SASL). 216490792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 216590792Sgshapiro immediately. 216690792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 216790792Sgshapiro allows checking of the return values of the DNS lookups. 216890792Sgshapiro See cf/README for details. 216990792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 217090792Sgshapiro temporary lookup failures. 217190792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 217290792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 217390792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 217490792Sgshapiro memory use. 217590792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 217690792Sgshapiro of the sender and the recipient address delimited by the 217790792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 217890792Sgshapiro in the access map. Based on code contributed by Mathias 217990792Sgshapiro Koerber of Singapore Telecommunications Ltd. 218090792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 218190792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 218290792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 218390792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 218490792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 218590792Sgshapiro the recipient host if LUSER_RELAY is used. 218690792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 218790792Sgshapiro +detail portion of the address when passing address to 218890792Sgshapiro local delivery agent.

Only use if LDA supports this. 219090792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 219190792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 219290792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 219390792Sgshapiro Routing lookups. Equivalent hostnames are replaced by the 219490792Sgshapiro masquerade domain name for lookups. See cf/README for 219590792Sgshapiro additional details. 219690792Sgshapiro CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which 219790792Sgshapiro instructs the rulesets on what to do if the address being 219890792Sgshapiro looked up has +detail information. See cf/README for more 219990792Sgshapiro information. 220090792Sgshapiro CONFIG: When chosing a new destination via LDAP Routing, also look 220190792Sgshapiro up the new routing address/host in the mailertable. Based 220290792Sgshapiro on patch from Don Badrak of the United States Census Bureau. 220390792Sgshapiro CONFIG: Do not reject the SMTP Mail from: command if LDAP Routing 220490792Sgshapiro is in use and the bounce option is enabled.

New option -D mbdb specifies the 227590792Sgshapiro mailbox database type. 227690792Sgshapiro MAIL.LOCAL: New option "-h filename" which instructs mail.local to 227790792Sgshapiro deliver the mail to the named file in the user's home 227890792Sgshapiro directory instead of the system mail spool area. Based on 227990792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 228090792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 228190792Sgshapiro doesn't truncate the statistics file. 228290792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 228390792Sgshapiro instead of white space. 228490792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 228590792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 228690792Sgshapiro Meteorological Institute. 228790792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 228890792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 228990792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 229090792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 229190792Sgshapiro instead of syslog. 229290792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 229390792Sgshapiro in the password file. The -f and -m options must be used 229490792Sgshapiro to specify the database and message file since there is no 229590792Sgshapiro home directory for the default settings for these options. 229690792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 229790792Sgshapiro local mail recipients; it reads the MailboxDatabase option 229890792Sgshapiro from the sendmail.cf file. New option -C cffile which 229990792Sgshapiro specifies the path of the sendmail.cf file. 230090792Sgshapiro New Directories: 230190792Sgshapiro libmilter/docs 230290792Sgshapiro New Files: 230390792Sgshapiro cf/cf/README 230490792Sgshapiro cf/cf/submit.cf 230590792Sgshapiro cf/cf/submit.mc 230690792Sgshapiro cf/feature/authinfo.m4 230790792Sgshapiro cf/feature/compat_check.m4 230890792Sgshapiro cf/feature/enhdnsbl.m4 230990792Sgshapiro cf/feature/msp.m4 231090792Sgshapiro cf/feature/local_no_masquerade.m4 231190792Sgshapiro cf/feature/lookupdotdomain.m4 231290792Sgshapiro cf/feature/preserve_luser_host.m4 231390792Sgshapiro cf/feature/preserve_local_plus_detail.m4 231490792Sgshapiro cf/feature/queuegroup.m4 231590792Sgshapiro cf/sendmail.schema 231690792Sgshapiro contrib/dnsblaccess.m4 231790792Sgshapiro devtools/M4/UNIX/sm-test.m4 231890792Sgshapiro devtools/OS/OpenUNIX.5.i386 231990792Sgshapiro editmap/* 232090792Sgshapiro include/sm/* 232190792Sgshapiro libsm/* 232290792Sgshapiro libsmutil/cf.c 232390792Sgshapiro libsmutil/err.c 232490792Sgshapiro sendmail/SECURITY 232590792Sgshapiro sendmail/TUNING 232690792Sgshapiro sendmail/bf.c 232790792Sgshapiro sendmail/bf.h 232890792Sgshapiro sendmail/sasl.c 232990792Sgshapiro sendmail/sm_resolve.c 233090792Sgshapiro sendmail/sm_resolve.h 233190792Sgshapiro sendmail/tls.c 233290792Sgshapiro Deleted Files: 233390792Sgshapiro cf/feature/rbl.m4 233490792Sgshapiro cf/ostype/aix2.m4 233590792Sgshapiro devtools/OS/AIX.2 233690792Sgshapiro include/sendmail/cdefs.h 233790792Sgshapiro include/sendmail/errstring.h 233890792Sgshapiro include/sendmail/useful.h 233990792Sgshapiro libsmutil/errstring.c 234090792Sgshapiro sendmail/bf_portable.c 234190792Sgshapiro sendmail/bf_portable.h 234290792Sgshapiro sendmail/bf_torek.c 234390792Sgshapiro sendmail/bf_torek.h 234490792Sgshapiro sendmail/clock.c 234590792Sgshapiro Renamed Files: 234690792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 234790792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 234890792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 234990792Sgshapiro 2350120256Sgshapiro8.11.7/8.11.7 2003/03/29 2351120256Sgshapiro SECURITY: Fix a remote buffer overflow in header parsing by 2352120256Sgshapiro dropping sender and recipient header comments if the 2353120256Sgshapiro comments are too long.

Problem noted by Marc G. 275866494Sgshapiro Fournier of Acadia University. 275966494Sgshapiro If an LDAP search fails because the LDAP server went down, close 276066494Sgshapiro the map so subsequent searches reopen the map. If there are 276166494Sgshapiro multiple LDAP servers, the down server will be skipped and 276266494Sgshapiro one of the others may be able to take over. 276366494Sgshapiro Set the ${load_avg} macro to the current load average, not the 276466494Sgshapiro previous load average query result. 276566494Sgshapiro If a non-optional map used in a check_* ruleset can't be opened, 276666494Sgshapiro return a temporary failure to the remote SMTP client 276766494Sgshapiro instead of ignoring the map. Problem noted by Allan E 276866494Sgshapiro Johannesen of Worcester Polytechnic Institute. 276966494Sgshapiro Avoid a race condition when queuing up split envelopes by saving 277066494Sgshapiro the split envelopes before the original envelope. 277166494Sgshapiro Fix a bug in the PH_MAP code which caused mail to bounce instead of 277266494Sgshapiro defer if the PH server could not be contacted.

Patch from Paul Hilchey of the 278366494Sgshapiro University of British Columbia. 278466494Sgshapiro Portability: 278566494Sgshapiro Move the NETINET6 define to devtools/OS/SunOS.5.{8,9} 278666494Sgshapiro instead of defining it in conf.h so users can 278766494Sgshapiro override the setting. Suggested by 278866494Sgshapiro Henrik Nordstrom of Ericsson. 278966494Sgshapiro On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of 279066494Sgshapiro /usr/lib/sendmail for rmail and vacation. From 279166494Sgshapiro Jeff A. Earickson of Colby College. 279266494Sgshapiro On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which 279366494Sgshapiro does not exist). From Jeff A.

This more closely 281566494Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 281666494Sgshapiro Ericsson. 281766494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 281866494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 281966494Sgshapiro mailer as described in cf/README. 282066494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 282166494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 282266494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 282366494Sgshapiro makemap to 'unmake' the map. 282466494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 282566494Sgshapiro sendmail. 282666494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 282766494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 282866494Sgshapiro Meteorological Institute. 282966494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 283066494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 283166494Sgshapiro dot as the only character on the line. 283266494Sgshapiro New Files: 283366494Sgshapiro cf/ostype/solaris8.m4 283466494Sgshapiro 283564562Sgshapiro8.11.0/8.11.0 2000/07/19 283664562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 283764562Sgshapiro (not the normal case), some operating systems will still 283864562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 283964562Sgshapiro to drop all of its privileges. If sendmail needs to drop 284064562Sgshapiro these privileges and the operating system doesn't set the 284164562Sgshapiro saved-uid as well, exit with an error. Problem noted by 284264562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 284364562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 284464562Sgshapiro it populates. It is possible that some broken 284564562Sgshapiro implementations of snprintf() exist that do not do this. 284664562Sgshapiro Systems in this category should compile with 284764562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 284864562Sgshapiro system and report broken implementations to 284964562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 285064562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 285164562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 285264562Sgshapiro Implementation influenced by the example programs of 285364562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 285464562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 285564562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 285664562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 285764562Sgshapiro cf/README and doc/op/op.*. 285864562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 285964562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 286064562Sgshapiro ${server_name}, and ${server_addr}. These are documented 286164562Sgshapiro in cf/README and doc/op/op.*. 286264562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 286364562Sgshapiro random data. 286464562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 286564562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 286664562Sgshapiro try to use STARTTLS despite the security problems. 286764562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 286864562Sgshapiro support encryption. Based on code contributed by Tim 286964562Sgshapiro Martin of CMU. 287064562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 287164562Sgshapiro strength factor. 287264562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 287364562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 287464562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 287564562Sgshapiro of CMU. 287664562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 287764562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 287864562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 287964562Sgshapiro Fix the default family selection for DaemonPortOptions. As 288064562Sgshapiro documented, unless a family is specified in a 288164562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 288264562Sgshapiro also the default if no DaemonPortOptions value is set. 288364562Sgshapiro Therefore, IPv6 users should configure additional sockets 288464562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 288564562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 288664562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 288764562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 288864562Sgshapiro the interface information for an outgoing connection. 288964562Sgshapiro Not doing so was creating a mismatch between the socket 289064562Sgshapiro family and address used in subsequent connections if the 289164562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 289264562Sgshapiro by John Beck of Sun Microsystems. 289364562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 289464562Sgshapiro family based on the IP address. ${if_family} is no longer 289564562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 289664562Sgshapiro of Sun Microsystems. 289764562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 289864562Sgshapiro macros for both the incoming interface address/family and 289964562Sgshapiro the outgoing interface address/family. In order for M=b 290064562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 290164562Sgshapiro the incoming information in the queue file for later 290264562Sgshapiro delivery attempts. 290364562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 290464562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 290564562Sgshapiro smoe.org. 290664562Sgshapiro Add more vigilance in checking for putc() errors on output streams 290764562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 290864562Sgshapiro noted by Graeme Hewson of Oracle. 290964562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 291064562Sgshapiro Problem noted by Ajay Matia. 291164562Sgshapiro Under certain circumstances, an address could be listed as deferred 291264562Sgshapiro but would be bounced back to the sender as failed to be 291364562Sgshapiro delivered when it really should have been queued. Problem 291464562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 291564562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 291664562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 291764562Sgshapiro Hedeland of Ericsson. 291864562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 291964562Sgshapiro is defined to avoid a core dump due to incompatibilities 292064562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 292164562Sgshapiro of Northern Illinois University. 292264562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 292364562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 292464562Sgshapiro Convert the free disk space shown in a control socket status query 292564562Sgshapiro to kilobyte units. 292664562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 292764562Sgshapiro looking up the hostname, requeue the message for a later 292864562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 292964562Sgshapiro Polytechnic. 293064562Sgshapiro Under the proper circumstances, failed connections would be recorded 293164562Sgshapiro as "Bad file number" instead of "Connection failed" in the 293264562Sgshapiro queue file and persistent host status. Problem noted by 293364562Sgshapiro Graeme Hewson of Oracle. 293464562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 293564562Sgshapiro within the hoststatus directory (e.g., lost+found). 293664562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 293764562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 293864562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 293964562Sgshapiro If a message data file can't be opened at delivery time, panic and 294064562Sgshapiro abort the attempt instead of delivering a message that 294164562Sgshapiro states "<<< No Message Collected >>>". 294264562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 294364562Sgshapiro restrictive. Problem noted by Mark G. Thomas of Mark 294464562Sgshapiro G. Thomas Consulting. 294564562Sgshapiro Preserve source port number instead of replacing it with the ident 294664562Sgshapiro port number (113). 294764562Sgshapiro Document the queue status characters in the mailq man page. 294864562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 294964562Sgshapiro Process queued items in which none of the recipient addresses have 295064562Sgshapiro host portions (or there are no recipients). Problem noted 295164562Sgshapiro by Valdis Kletnieks of Virginia Tech. 295264562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 295364562Sgshapiro only the first to open the connection is allowed to close 295464562Sgshapiro it so a later map close doesn't break the connection for 295564562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 295664562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 295764562Sgshapiro authentication. Patch from Rainer Schoepf of the 295864562Sgshapiro University of Mainz. 295964562Sgshapiro Provide workaround for inconsistent handling of data passed 296064562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 296164562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

This option and 321664562Sgshapiro its use is deprecated and will be removed from a future 321764562Sgshapiro version of sendmail. 321864562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 321964562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 322064562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 322164562Sgshapiro (IdS). 322264562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 322364562Sgshapiro a large number of files. See cf/README for more details. 322464562Sgshapiro The directory structure of the distribution has changed slightly 322564562Sgshapiro for easier code sharing among the programs. 322664562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 322764562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 322864562Sgshapiro which hold the client's authentication credentials, 322964562Sgshapiro the mechanism used for authentication, and the 323064562Sgshapiro authorization identity (i.e., the AUTH= parameter if 323164562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 323264562Sgshapiro On systems which use the Torek stdio library (all of the BSD 323364562Sgshapiro distributions), use memory-buffered files to reduce 323464562Sgshapiro file system overhead by not creating temporary files on 323564562Sgshapiro disk. Contributed by Exactis.com, Inc. 323664562Sgshapiro New option DataFileBufferSize to control the maximum size of a 323764562Sgshapiro memory-buffered data (df) file before a disk-based file is 323864562Sgshapiro used.

Contributed by Exactis.com, Inc. 324264562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 324364562Sgshapiro now listen on several different ports. Use: 324464562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 324564562Sgshapiro to run a Message Submission Agent (MSA); this is turned 324664562Sgshapiro on by default in m4-generated .cf files; it can be turned 324764562Sgshapiro off with FEATURE(`no_default_msa'). 324864562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 324964562Sgshapiro begin using RFC 2476 Message Submission for initial user 325064562Sgshapiro message submission. XUSR may disappear from a future release. 325164562Sgshapiro The new '-G' (relay (gateway) submission) command line option 325264562Sgshapiro indicates that the message being submitted from the command 325364562Sgshapiro line is for relaying, not initial submission. This means 325464562Sgshapiro the message will be rejected if the addresses are not fully 325564562Sgshapiro qualified and no canonicalization will be done. Future 325664562Sgshapiro releases may even reject improperly formed messages. 325764562Sgshapiro The '-U' (initial user submission) command line option is 325864562Sgshapiro deprecated and may be removed from a future release. 325964562Sgshapiro Mail user agents should begin using '-G' to indicate that 326064562Sgshapiro this is a relay submission (the inverse of -U). 326164562Sgshapiro The next release of sendmail will assume that any message submitted 326264562Sgshapiro from the command line is an initial user submission and act 326364562Sgshapiro accordingly. 326464562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 326564562Sgshapiro program or deliver to file as the owner of that file, the 326664562Sgshapiro address is marked as unsafe. This means if RunAsUser is 326764562Sgshapiro set, users won't be able to use programs or delivery to 326864562Sgshapiro files in their .forward files. Administrators can override 326964562Sgshapiro this by setting the DontBlameSendmail option to the new 327064562Sgshapiro setting NonRootSafeAddr. 327164562Sgshapiro Allow group or world writable directories if the sticky bit is set 327264562Sgshapiro on the directory and DontBlameSendmail is set to 327364562Sgshapiro TrustStickyBit.

To use multiple queues, supply 330664562Sgshapiro a QueueDirectory option value ending with an asterisk. For 330764562Sgshapiro example, /var/spool/mqueue/q* will use all of the 330864562Sgshapiro directories or symbolic links to directories beginning with 330964562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 331064562Sgshapiro mind, the queue directory structure should not be changed 331164562Sgshapiro while sendmail is running. Queue runs create a separate 331264562Sgshapiro process for running each queue unless the verbose flag is 331364562Sgshapiro given on a non-daemon queue run. New items are randomly 331464562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 331564562Sgshapiro Support different directories for qf, df, and xf queue files; if 331664562Sgshapiro subdirectories or symbolic links to directories of those names 331764562Sgshapiro exist in the queue directories, they are used for the 331864562Sgshapiro corresponding queue files. Keep in mind, the queue 331964562Sgshapiro directory structure should not be changed while sendmail is 332064562Sgshapiro running. Proposed by Mathias Koerber of Singapore 332164562Sgshapiro Telecommunications Ltd. 332264562Sgshapiro New queue file naming system which uses a filename guaranteed to be 332364562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 332464562Sgshapiro without fancy file system locking. Queued items can be 332564562Sgshapiro moved between queues easily.

This 333364562Sgshapiro avoids opening and reading each queue file when preparing 333464562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 333564562Sgshapiro Shared memory counters and microtimers functionality has been 333664562Sgshapiro donated by Exactis.com, Inc. 333764562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 333864562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 333964562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 334064562Sgshapiro being added. Suggested by Michael K. Sanders. 334164562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 334264562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 334364562Sgshapiro and John Beck of Sun Microsystems. 334464562Sgshapiro In low-disk space situations, where sendmail would previously refuse 334564562Sgshapiro connections, still accept them, but only allow ETRN commands. 334664562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 334764562Sgshapiro Ltd. 334864562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 334964562Sgshapiro on systems which support them. This can be used with LMTP 335064562Sgshapiro local delivery agents which listen on a named socket. An 335164562Sgshapiro example mailer might be: 335264562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 335364562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 335464562Sgshapiro A=FILE /var/run/lmtpd 335564562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 335664562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 335764562Sgshapiro instead. 335864562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 335964562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 336064562Sgshapiro connections), IPC (which will be deprecated in a future 336164562Sgshapiro version), and FILE (for UNIX domain socket delivery). 336264562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 336364562Sgshapiro flags. 336464562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 336564562Sgshapiro body of the original message on delivery status 336664562Sgshapiro notifications. 336764562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 336864562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 336964562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 337064562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 337164562Sgshapiro Steve Schweinhart of America Online. 337264562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 337364562Sgshapiro not be set after rulesets are defined. Suggested by 337464562Sgshapiro Mitchell Blank Jr of Exec-PC. 337564562Sgshapiro Do not report temporary failure on delivery to files. In 337664562Sgshapiro interactive delivery mode, this would result in two SMTP 337764562Sgshapiro responses after the DATA command. Problem noted by 337864562Sgshapiro Nik Conwell of Boston University. 337964562Sgshapiro Check file close when mailing to files. Problem noted by Nik 338064562Sgshapiro Conwell of Boston University. 338164562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 338264562Sgshapiro Curtis W. Hillegas of Princeton University. 338364562Sgshapiro Always bind to the LDAP server regardless of whether you are using 338464562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 338564562Sgshapiro @Home Network. 338664562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 338764562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 338864562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 338964562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 339064562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 339164562Sgshapiro similar to check_rcpt etc. 339264562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 339364562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 339464562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 339564562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 339664562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 339764562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 339864562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 339964562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 340064562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 340164562Sgshapiro the corresponding DSN parameter values. Proposed by 340264562Sgshapiro Mathias Herberts. 340364562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 340464562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 340564562Sgshapiro before the message has been collected, thereafter it holds 340664562Sgshapiro the message size as computed by sendmail (and can be used 340764562Sgshapiro in check_compat). 340864562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 340964562Sgshapiro sendmail is using instead of the value of the DeliveryMode 341064562Sgshapiro option. 341164562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 341264562Sgshapiro Drop explicit From: if same as what would be generated only if it is 341364562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 341464562Sgshapiro Write pid to file also if sendmail only processes the queue. 341564562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 341664562Sgshapiro Log "low on disk space" only when necessary. 341764562Sgshapiro New macro ${load_avg} can be used to check the current load average. 341864562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 341964562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 342064562Sgshapiro is set. 342164562Sgshapiro Flag -S for maps to specify the character which is substituted 342264562Sgshapiro for spaces (instead of the default given by O BlankSub). 342364562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 342464562Sgshapiro This flag is set by default for the host map. Based on a 342564562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 342664562Sgshapiro Open maps only on demand, not at startup. 342764562Sgshapiro Log warning about unsupported IP address families. 342864562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 342964562Sgshapiro of the sum of all headers. This can be used to prevent 343064562Sgshapiro a denial-of-service attack. 343164562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 343264562Sgshapiro headers and parameters within those headers. This option 343364562Sgshapiro is intended to protect mail user agents from buffer 343464562Sgshapiro overflow attacks. 343564562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 343664562Sgshapiro alias recursion. 343764562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 343864562Sgshapiro Map type syslog to log the key via syslogd. 343964562Sgshapiro Entries in the alias file can be continued by putting a backslash 344064562Sgshapiro directly before the newline. 344164562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 344264562Sgshapiro dead.letter file, formerly hardcoded to 344364562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 344464562Sgshapiro default), sendmail will not attempt to save to a 344564562Sgshapiro system-wide dead.letter file if it can not bounce the mail 344664562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 344764562Sgshapiro file as it has in the past when the dead.letter file 344864562Sgshapiro could not be opened. 344964562Sgshapiro New option PidFile to define the location of the pid file. The 345064562Sgshapiro value of this option is macro expanded. 345164562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 345264562Sgshapiro process title shown in 'ps' listings. 345364562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 345464562Sgshapiro (along with the already existing macros): 345564562Sgshapiro ${daemon_info} Daemon information, e.g. 345664562Sgshapiro SMTP+queueing@00:30:00 345764562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 345864562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 345964562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 346064562Sgshapiro ${daemon_port} Daemon port, e.g., 25 346164562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 346264562Sgshapiro New macros especially for virtual hosting: 346364562Sgshapiro ${if_name} hostname of interface of incoming connection. 346464562Sgshapiro ${if_addr} address of interface of incoming connection. 346564562Sgshapiro The latter is only set if the interface does not belong to the 346664562Sgshapiro loopback net. 346764562Sgshapiro If a message being accepted via a method other than SMTP and 346864562Sgshapiro would be rejected by a header check, do not send the message. 346964562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 347064562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 347164562Sgshapiro Provide header value as quoted string in the macro 347264562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 347364562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 347464562Sgshapiro The length of the header value is stored in ${hdrlen}. 347564562Sgshapiro H*: allows to specify a default ruleset for header checks. This 347664562Sgshapiro ruleset will only be called if the individual header does 347764562Sgshapiro not have its own ruleset assigned. Suggested by Jan 347864562Sgshapiro Krueger of Unix-AG of University of Hannover. 347964562Sgshapiro The name of the header field stored in ${hdr_name}. 348064562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 348164562Sgshapiro removed if the config file version is greater than or equal 348264562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 348364562Sgshapiro input "token (1)" but does not match "token". 348464562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 348564562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 348664562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 348764562Sgshapiro Ericsson. 348864562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 348964562Sgshapiro messages with 8-bit text in headers. Problem noted by 349064562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 349164562Sgshapiro of Ericsson. 349264562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 349364562Sgshapiro modified database map file. Problem noted by Chris Adams 349464562Sgshapiro of Renaissance Internet Services. 349564562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 349664562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 349764562Sgshapiro queue up the message instead of bouncing it. 349864562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 349964562Sgshapiro standard does not provide any indication of what to do when 350064562Sgshapiro something other than 250 is received. Based on a patch 350164562Sgshapiro from Steve Schweinhart of America Online. 350264562Sgshapiro New option TrustedUser allows to specify a user who can own 350364562Sgshapiro important files instead of root. This requires HASFCHOWN. 350464562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 350564562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 350664562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 350764562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 350864562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 350964562Sgshapiro $? tests also whether the macro is non-null. 351064562Sgshapiro Print an error message if a mailer definition contains an invalid 351164562Sgshapiro equate name. 351264562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 351364562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 351464562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 351564562Sgshapiro mailer to return after sending all data to it. 351664562Sgshapiro Only free memory from the process list when adding a new process 351764562Sgshapiro into a previously filled slot. Previously, the memory was 351864562Sgshapiro freed at removal time. Since removal can happen in a 351964562Sgshapiro signal handler, this may leave the memory map in an 352064562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 352164562Sgshapiro David Cooley of Colby College. 352264562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 352364562Sgshapiro local users in the passwd file. The UserDB code has 352464562Sgshapiro already decided the message will be passed to another host 352564562Sgshapiro for processing. Fix from Tony Landells of Burdett 352664562Sgshapiro Buckeridge Young Limited. 352764562Sgshapiro Support LDAP authorization via either a file containing the 352864562Sgshapiro password or Kerberos V4 using the new map options 352964562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 353064562Sgshapiro distinguished_name is who to login as. The method can be 353164562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 353264562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 353364562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 353464562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 353564562Sgshapiro of Stanford University. 353664562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 353764562Sgshapiro deprecated and will be removed in a future version. 353864562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 353964562Sgshapiro and the map has the column delimiter set, it turns that 354064562Sgshapiro response into a delimiter separated string. The LDAP map 354164562Sgshapiro will traverse multiple entries as well. LDAP alias maps 354264562Sgshapiro automatically set the column delimiter to the comma. 354364562Sgshapiro Based on patch from Booker Bense of Stanford University and 354464562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 354564562Sgshapiro Support return of multiple values for a single LDAP lookup. The 354664562Sgshapiro values to be returned should be in a comma separated string. 354764562Sgshapiro For example, `-v "email,emailother"'. Patch from 354864562Sgshapiro Curtis W. Hillegas of Princeton University. 354964562Sgshapiro Allow the use of LDAP for alias maps. 355064562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 355164562Sgshapiro attributes found in the match will be returned. 355264562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 355364562Sgshapiro breaking up a single entry into multiple entries. This is 355464562Sgshapiro needed for LDAP alias file specifications to allow for 355564562Sgshapiro comma separated key and value strings. 355664562Sgshapiro Keep connections to LDAP server open instead of opening and closing 355764562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 355864562Sgshapiro connections such that multiple maps which use the same 355964562Sgshapiro host, port, bind DN, and authentication will only result in 356064562Sgshapiro a single connection to that host. 356164562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 356264562Sgshapiro Be more careful about checking for errors and freeing memory on 356364562Sgshapiro LDAP lookups. 356464562Sgshapiro Use asynchronous LDAP searches to save memory and network 356564562Sgshapiro resources. 356664562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 356764562Sgshapiro Increase portability to the Netscape LDAP libraries. 356864562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 356964562Sgshapiro replaced with the literal contents of the map lookup key -- 357064562Sgshapiro note that this means a lookup can be done using the LDAP 357164562Sgshapiro special characters. The new '%0' token can be used instead 357264562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 357364562Sgshapiro For example, if the LDAP map specification contains '-k 357464562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 357564562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 357664562Sgshapiro user attribute. Instead, if the LDAP map specification 357764562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 357864562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 357964562Sgshapiro with the name "*". 358064562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 358164562Sgshapiro more than one is returned, it is equivalent to no records 358264562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 358364562Sgshapiro alias dereference option; "-Z size" limits the number of 358464562Sgshapiro matches to return. 358564562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 358664562Sgshapiro LDAP maps. The value should only contain LDAP specific 358764562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 358864562Sgshapiro settings will be used for all LDAP maps unless they are 358964562Sgshapiro specified in the individual map specification ('K' 359064562Sgshapiro command). This option should be set before any LDAP maps 359164562Sgshapiro are defined. 359264562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 359364562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 359464562Sgshapiro Tech. 359564562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 359664562Sgshapiro particular, class entries get much smaller, which can be 359764562Sgshapiro important if you have large classes. 359864562Sgshapiro On network-related temporary failures, record the hostname which 359964562Sgshapiro gave error in the queued status message. Requested by 360064562Sgshapiro Ulrich Windl of the Universitat Regensburg. 360164562Sgshapiro Add new F=% mailer flag to allow for a store and forward 360264562Sgshapiro configuration. Mailers which have this flag will not attempt 360371345Sgshapiro delivery on initial receipt of a message or on queue runs 360464562Sgshapiro unless the queued message is selected using one of the 360564562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 360664562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 360764562Sgshapiro New option ControlSocketName which, when set, creates a daemon 360864562Sgshapiro control socket. This socket allows an external program to 360964562Sgshapiro control and query status from the running sendmail daemon 361064562Sgshapiro via a named socket, similar to the ctlinnd interface to the 361164562Sgshapiro INN news server. Access to this interface is controlled by 361264562Sgshapiro the UNIX file permissions on the named socket on most UNIX 361364562Sgshapiro systems (see sendmail/README for more information). An 361464562Sgshapiro example control program is provided as contrib/smcontrol.pl. 361564562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 361664562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 361764562Sgshapiro number of processors online on the system (if that can be 361864562Sgshapiro determined). For single processor machines, this change 361964562Sgshapiro has no effect. 362064562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 362164562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 362264562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 362364562Sgshapiro Motonori Nakamura of Kyoto University. 362464562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 362564562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 362664562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 362764562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 362864562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 362964562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 363064562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 363164562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 363264562Sgshapiro connection-based denial of service attacks. 363364562Sgshapiro Log basic information about authenticated connections at LogLevel 363464562Sgshapiro 10 or higher. 363564562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 363664562Sgshapiro information (from= syslog line). 363764562Sgshapiro Log the DSN code for each recipient if one is available as a new 363864562Sgshapiro equate (dsn=). 363964562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 3640120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 3641120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 3642120256Sgshapiro of the University of Illinois at Urbana-Champaign. 364364562Sgshapiro Detect temporary lookup failures in the host map if looking up a 364464562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 364564562Sgshapiro Finnish Meteorological Institute. 364664562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 364764562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 364864562Sgshapiro When a forward file points to an alias which runs a program, run 364964562Sgshapiro the program as the default user and the default group, not 365064562Sgshapiro the forward file user. This change also assures the 365164562Sgshapiro :include: directives in aliases are also processed using 365264562Sgshapiro the default user and group. Problem noted by Sergiu 365364562Sgshapiro Popovici of DNT Romania. 365464562Sgshapiro Prevent attempts to save a dead.letter file for a user with 365564562Sgshapiro no home directory (/no/such/directory). Problem noted by 365664562Sgshapiro Michael Brown of Finnigan FT/MS. 365764562Sgshapiro Include message delay and number of tries when logging that a 365864562Sgshapiro message has been completely delivered (LogLevel of 10 or 365964562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 366064562Sgshapiro Log the sender of a message even if none of the recipients were 366164562Sgshapiro accepted. If some of the recipients were rejected, it is 366264562Sgshapiro helpful to know the sender of the message. 366364562Sgshapiro Check the root directory (/) when checking a path for safety. 366464562Sgshapiro Problem noted by John Beck of Sun Microsystems. 366564562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 366664562Sgshapiro interactive and delivering to an alias which resolves to 366764562Sgshapiro multiple files. 366864562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 366964562Sgshapiro greater (see below); the help function doesn't print the 367064562Sgshapiro version of sendmail any longer, instead it is placed in 367164562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 367264562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 367364562Sgshapiro skipped and a version line (#vers) is introduced. The 367464562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 367564562Sgshapiro version is found, a warning is logged. The '#vers' 367664562Sgshapiro directive should be placed at the top of the help file. 367764562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 367864562Sgshapiro disk succeeded. Suggested by Nick Christenson. 367964562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 368064562Sgshapiro length before the attempt. 368164562Sgshapiro If a forward points to a filename for delivery, change to the 368264562Sgshapiro user's uid before checking permissions on the file. This 368364562Sgshapiro allows delivery to files on NFS mounted directories where 368464562Sgshapiro root is remapped to nobody. Problem noted by Harald 368564562Sgshapiro Daeubler of Universitaet Ulm. 368664562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 368764562Sgshapiro host status files, not all files. 368864562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 368964562Sgshapiro in the queue file for the message and set when delivery 369064562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 369164562Sgshapiro Wonderworks Inc. 369264562Sgshapiro Add support for storing information between rulesets using the new 369364562Sgshapiro macro map class. This can be used to store information 369464562Sgshapiro between queue runs as well using $={persistentMacros}. 369564562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 369664562Sgshapiro of Hannover. 369764562Sgshapiro New map class arith to allow for computations in rules. The 369864562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 369964562Sgshapiro as key. The two operands are specified as arguments; the 370064562Sgshapiro lookup returns the result of the computation. For example, 370164562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 370264562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 370364562Sgshapiro Add new syntax for header declarations which decide whether to 370464562Sgshapiro include the header based on a macro rather than a mailer 370564562Sgshapiro flag: 370664562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 370764562Sgshapiro This should be used along with $={persistentMacros}. 370864562Sgshapiro It can be used for adding headers to a message based on 370964562Sgshapiro the results of check_* and header check rulesets. 371064562Sgshapiro Allow new named config file rule check_eoh which is called after 371164562Sgshapiro all of the headers have been collected. The input to the 371264562Sgshapiro ruleset the number of headers and the size of all of the 371364562Sgshapiro headers in bytes separated by $|. This ruleset along with 371464562Sgshapiro the macro storage map can be used to correlate information 371564562Sgshapiro gathered between headers and to check for missing headers. 371664562Sgshapiro See cf/README or doc/op/op.ps for an example. 371764562Sgshapiro Change the default for the MeToo option to True to correspond 371864562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 371964562Sgshapiro option is deprecated and will be removed from a future 372064562Sgshapiro version. 372164562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 372264562Sgshapiro Change the sendmail binary default for SuperSafe to True. 372364562Sgshapiro Display ruleset names in debug and address test mode output 372464562Sgshapiro if referencing a named ruleset. 372564562Sgshapiro New mailer equate m= which will limit the number of messages 372664562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 372764562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 372864562Sgshapiro using it to sort. Now all the same domains are really run 372964562Sgshapiro through the queue together. If they have the same MX host, 373064562Sgshapiro then they will have a much better opportunity to use the 373164562Sgshapiro connection cache if available. This should be a reasonable 373264562Sgshapiro performance improvement. Patch from Randall Winchester of 373364562Sgshapiro the University of Maryland. 373464562Sgshapiro If a message is rejected by a header check ruleset, log who would 373564562Sgshapiro have received the message if it had not been rejected. 373664562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 373764562Sgshapiro queue immediately. No delivery attempt is made. 373864562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 373964562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 374064562Sgshapiro COMMANDS). 374164562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 374264562Sgshapiro but for outgoing connections. 374364562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 374464562Sgshapiro error messages and logging) and Modifiers, i.e. 374564562Sgshapiro a require authentication 374664562Sgshapiro b bind to interface through which mail has 374764562Sgshapiro been received 374864562Sgshapiro c perform hostname canonification 374964562Sgshapiro f require fully qualified hostname 375064562Sgshapiro h use name of interface for outgoing HELO 375164562Sgshapiro command 375264562Sgshapiro C don't perform hostname canonification 375364562Sgshapiro E disallow ETRN (see RFC 2476) 375464562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 375564562Sgshapiro h use name of interface for HELO command 375664562Sgshapiro The version number for queue files (qf) has been incremented to 4. 375764562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 375864562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 375964562Sgshapiro Institutes of Health. 376064562Sgshapiro If a mailer dies, print the status in decimal instead of octal 376164562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 376264562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 376364562Sgshapiro Move message priority from sender to recipient logging. Suggested by 376464562Sgshapiro Ulrich Windl of the Universitat Regensburg. 376564562Sgshapiro Add support for Berkeley DB 3.X. 376664562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 376764562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 376864562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 376964562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 377064562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 377164562Sgshapiro sub-options is set on the command line. Problem noted by 377264562Sgshapiro Graeme Hewson of Oracle. 377364562Sgshapiro Randomize equal preference MX records each time delivery is 377464562Sgshapiro attempted via a new connection to a host instead of once per 377564562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 377664562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 377764562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 377864562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 377964562Sgshapiro to hosts which have dynamically assigned names. 378064562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 378164562Sgshapiro the bounce for the same reason. If the body is not 8-bit 378264562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 378364562Sgshapiro not be included in the bounce. Problem noted by Valdis 378464562Sgshapiro Kletnieks of Virginia Tech. 378564562Sgshapiro The timeout for sending a message via SMTP has been changed from 378664562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 378764562Sgshapiro simply checks for progress on sending data every 5 minutes. 378864562Sgshapiro This will detect the inability to send information quicker 378964562Sgshapiro and reduce the number of processes simply waiting to 379064562Sgshapiro timeout. 379164562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 379264562Sgshapiro interface address structure when loading the system network 379364562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 379464562Sgshapiro Nanoteq. 379564562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 379664562Sgshapiro indicates the number of interfaces to read when probing 379764562Sgshapiro for hostnames and IP addresses for class w ($=w). The 379864562Sgshapiro default value is 512. Based on idea from Reinier 379964562Sgshapiro Bezuidenhout of Nanoteq. 380064562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 380164562Sgshapiro on load average. 380264562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 380364562Sgshapiro Northern Illinois University. 380464562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 380564562Sgshapiro envelope splitting has occurred. 380664562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 380764562Sgshapiro Luke Mewburn from RMIT University. 380864562Sgshapiro Add a "/quit" command to address test mode. 380964562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 381064562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 381164562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 381264562Sgshapiro Institute. 381364562Sgshapiro The contents of a class can now be copied to another class using 381464562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 381564562Sgshapiro the items in class $={Source} into the class $={Dest}. 381664562Sgshapiro Include original envelope's error transcript in bounces created for 381764562Sgshapiro split (owner-) envelopes to see the original errors when 381864562Sgshapiro the recipients were added. Based on fix from Motonori 381964562Sgshapiro Nakamura of Kyoto University. 382064562Sgshapiro Show reason for permanent delivery errors directly after the 382164562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 382264562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 382364562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 382464562Sgshapiro If the specification for the queue run interval (-q###) has a 382564562Sgshapiro syntax error, consider the error fatal and exit. 382664562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 382764562Sgshapiro noted by Motonori Nakamura of Kyoto University. 382864562Sgshapiro On operating systems which have setlogin(2), use it to set the 382964562Sgshapiro login name to the RunAsUserName when starting as a daemon. 383064562Sgshapiro This is for delivery to programs which use getlogin(). 383164562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 383264562Sgshapiro Differentiate between "command not implemented" and "command 383364562Sgshapiro unrecognized" in the SMTP dialogue. 383464562Sgshapiro Strip returns from forward and include files. Problem noted by 383564562Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 383664562Sgshapiro Prevent a core dump when using 'sendmail -bv' on an address which 383764562Sgshapiro resolves to the $#error mailer with a temporary failure. 383864562Sgshapiro Based on fix from Neil Rickert of Northern Illinois 383964562Sgshapiro University. 384064562Sgshapiro Prevent multiple deliveries of a message with a "non-local alias" 384164562Sgshapiro pointing to a local user, if canonicalization fails 384264562Sgshapiro the message was requeued *and* delivered to the alias. 384364562Sgshapiro If an invalid ruleset is declared, the ruleset name could be 384464562Sgshapiro ignored and its rules added to S0. Instead, ignore the 384564562Sgshapiro ruleset lines as well. 384664562Sgshapiro Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient 384764562Sgshapiro success DSN fields as well as duplicate entries for a 384864562Sgshapiro single address due to S5 and UserDB processing. Problems 384964562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological 385064562Sgshapiro Institute. 385164562Sgshapiro Turn off timeouts when exiting sendmail due to an interrupt signal 385264562Sgshapiro to prevent the timeout from firing during the exit process. 385364562Sgshapiro Problem noted by Michael Shapiro of Sun Microsystems. 385464562Sgshapiro Do not append @MyHostName to non-RFC822 addresses output by the EXPN 385564562Sgshapiro command or on Final-Recipient: and X-Actual-Recipient: DSN 385664562Sgshapiro headers. Non-RFC822 addresses include deliveries to 385764562Sgshapiro programs, file, DECnet, etc. 385864562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 385964562Sgshapiro spoof their return address. Based on idea from Neil Rickert 386064562Sgshapiro of Northern Illinois University and patch from Per Hedeland 386164562Sgshapiro of Ericsson. 386264562Sgshapiro Report the proper UID in the bounce message if an :include: file is 386364562Sgshapiro owned by a uid that doesn't map to a username and the 386464562Sgshapiro :include: file contains delivery to a file or program. 386564562Sgshapiro Problem noted by John Beck of Sun Microsystems. 386664562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 386764562Sgshapiro the remote server responds to the first QUIT with a 4xx 386864562Sgshapiro response code and drops the connection. This behavior was 386964562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 387064562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 387164562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 387264562Sgshapiro file is not present, the lookup failure would be marked as 387364562Sgshapiro a permanent failure instead of a temporary failure. Fix 387464562Sgshapiro from Russell King of the ARM Linux Project. 387564562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 387664562Sgshapiro instead of spaces between arguments. Problem noted by Randy 387764562Sgshapiro Wormser. Fix from Neil Rickert of Northern Illinois 387864562Sgshapiro University. 387964562Sgshapiro Allow MaxRecipientsPerMessage option to be set on the command line 388064562Sgshapiro by normal users (e.g., sendmail won't drop its root 388164562Sgshapiro privileges) to allow overrides for message submission via 388264562Sgshapiro 'sendmail -bs'. 388364562Sgshapiro Set the names for help file and statistics file to "helpfile" and 388464562Sgshapiro "statistics", respectively, if no parameters are given for 388564562Sgshapiro them in the .cf file. 388664562Sgshapiro Avoid bogus 'errbody: I/O Error -7' log messages when sending 388764562Sgshapiro success DSN messages for messages relayed to non-DSN aware 388864562Sgshapiro systems. Problem noted by Juergen Georgi of RUS University 388964562Sgshapiro of Stuttgart and Kyle Tucker of Parexel International. 389064562Sgshapiro Prevent +detail information from interfering with local delivery to 389164562Sgshapiro multiple users in the same transaction (F=m). 389264562Sgshapiro Add H_FORCE flag for the X-Authentication-Warning: header, so it 389364562Sgshapiro will be added even if one already exists. Problem noted 389464562Sgshapiro by Michal Zalewski of Marchew Industries. 389564562Sgshapiro Stop processing SMTP commands if the SMTP connection is dropped. 389664562Sgshapiro This prevents a remote system from flooding the connection 389764562Sgshapiro with commands and then disconnecting. Previously, the 389864562Sgshapiro server would process all of the buffered commands. Problem 389964562Sgshapiro noted by Michal Zalewski of Marchew Industries. 390064562Sgshapiro Properly process user-supplied headers beginning with '?'. Problem 390164562Sgshapiro noted by Michal Zalewski of Marchew Industries. 390264562Sgshapiro If multiple header checks resolve to the $#error mailer, use the 390364562Sgshapiro last permanent (5XX) failure if any exist. Otherwise, use 390464562Sgshapiro the last temporary (4XX) failure. 390564562Sgshapiro RFC 1891 requires "hexchar" in a "xtext" to be upper case. Patch 390664562Sgshapiro from Ronald F. Guilmette of Infinite Monkeys & Co. 390764562Sgshapiro Timeout.ident now defaults to 5 seconds instead of 30 seconds to 390864562Sgshapiro prevent the now common delays associated with mailing to a 390964562Sgshapiro site which drops IDENT packets. Suggested by many. 391064562Sgshapiro Persistent host status data is not reloaded disk when current data 391164562Sgshapiro is available in the in-memory cache. Problem noted by Per 391264562Sgshapiro Hedeland of Ericsson. 391364562Sgshapiro mailq displays unprintable characters in addresses as their octal 391464562Sgshapiro representation and a leading backslash. This avoids problems 391564562Sgshapiro with "unprintable" characters. Problem noted by Michal 391664562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 391764562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 391864562Sgshapiro one character past the limit. This would cause subsequent 391964562Sgshapiro hops to break the line again. The '!' is now placed in 392064562Sgshapiro the last column of the limit if the line needs to be broken. 392164562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 392264562Sgshapiro from Per Hedeland of Ericsson. 392364562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 392464562Sgshapiro resolver will fall back to TCP. However, some 392564562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 392664562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 392764562Sgshapiro don't fail on ANY queries. 392864562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 392964562Sgshapiro address, do not send an empty postmaster notification DSN 393064562Sgshapiro to the postmaster.

Suggested by Bryan Costales of Exactis. 424264562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 424364562Sgshapiro building of the man pages when defined. Suggested by Bryan 424464562Sgshapiro Costales. 424564562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 424664562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 424764562Sgshapiro installation of the sendmail helpfile and statistics file 424864562Sgshapiro respectively. Suggested by Bryan Costales. 424964562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 425064562Sgshapiro of Siemens Business Services. 425164562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 425264562Sgshapiro stdio library. The new buffered file I/O depends on the 425364562Sgshapiro Torek stdio library. This option can be either portable or 425464562Sgshapiro torek. 425564562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 425664562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 425764562Sgshapiro They should contain the C source files for the object files 425864562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 425964562Sgshapiro will be passed to the 'make depend' stage of compilation. 426064562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 426164562Sgshapiro in the sendmail distribution. Each has the form 426264562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 426364562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 426464562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 426564562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 426664562Sgshapiro building the distribution, but documentation on the changes 426764562Sgshapiro are in devtools/README. 426864562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 426964562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 427064562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 427164562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 427264562Sgshapiro new variable which identifies the root of the source 427364562Sgshapiro directories for all of the programs in the distribution. 427464562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 427564562Sgshapiro time. They can both still be overridden by setting the m4 427664562Sgshapiro macro. 427764562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 427864562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 427964562Sgshapiro build configurations, and places objects in obj.prefix.*/. 428064562Sgshapiro Complains as 'Build -f file' does for existing object 428164562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 428264562Sgshapiro Corporation. 428364562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 428464562Sgshapiro manual pages in the directory tree specified by 428564562Sgshapiro confMANROOTMAN. 428664562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 428764562Sgshapiro preformatted pages from the distribution. The new variable 428864562Sgshapiro confCOPY specifies the copying program. 428964562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 429064562Sgshapiro question. Suggested by Terry Lambert of Whistle 429164562Sgshapiro Communications. 429264562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 429364562Sgshapiro of the installed statistics and help files, respectively. 429464562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 429564562Sgshapiro operating system identity. Problem noted by Erik 429664562Sgshapiro Wachtenheim of Dartmouth College. 429764562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 429864562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 429964562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 430064562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 430164562Sgshapiro how to strip binaries. These are used by the new 430264562Sgshapiro install-strip target. 430364562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 430464562Sgshapiro the others (if it exists). 430564562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 430664562Sgshapiro then the default ones. 430790792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 430864562Sgshapiro as local delivery agent without LMTP mode, use 430964562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 431064562Sgshapiro to set the S flag. 431164562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 431264562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 431364562Sgshapiro Northern Illinois University. 431464562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 431564562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 431664562Sgshapiro the Finnish Meteorological Institute. 431764562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 431864562Sgshapiro MAILLOCK when compiling. Also requires linking with 431964562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 432064562Sgshapiro University. 432164562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 432264562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 432364562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 432464562Sgshapiro University. 432564562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 432664562Sgshapiro structure to the beginning of the program. This ensures that 432764562Sgshapiro the getservbyname() is done before any seteuid to a possibly 432864562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 432964562Sgshapiro on a Solaris system, this avoids syslog messages such as, 433064562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 433164562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 433264562Sgshapiro University. 433364562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 433464562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 433564562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 433664562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 433764562Sgshapiro characters (in LMTP mode), mail.local split the incoming 433864562Sgshapiro line up into 2046-character output lines (excluding the 433964562Sgshapiro newline). If an input line was 2047 characters long 434064562Sgshapiro (excluding CR-LF) and the last character was a '.', 434164562Sgshapiro mail.local saw it as the end of input, transfered it to the 434264562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 434364562Sgshapiro If the message was much longer, both sendmail and 434464562Sgshapiro mail.local would deadlock waiting for each other to read 434564562Sgshapiro what they have written. Problem noted by Peter Jeremy of 434664562Sgshapiro Alcatel Australia Limited. 434764562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 434864562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 434964562Sgshapiro Neil Rickert of Northern Illinois University. 435064562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 435164562Sgshapiro timeout to avoid starvation. 435264562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 435364562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 435464562Sgshapiro Infinite Monkeys & Co. 435564562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 435664562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 435764562Sgshapiro printed in a machine readable fashion and the stats file 435864562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 435964562Sgshapiro of Maryland. 436064562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 436164562Sgshapiro generated maps to the TrustedUser as specified in the 436264562Sgshapiro sendmail configuration file. 436364562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 436464562Sgshapiro configuration file to use for finding the TrustedUser 436564562Sgshapiro option. 436664562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 436764562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 436864562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 436964562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 437064562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 437164562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 437264562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 437364562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 437464562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 437564562Sgshapiro Corporation UK. 437664562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 437764562Sgshapiro (e.g., sendmail would not drop root privileges if the 437864562Sgshapiro option was specified on the command line). Problem noted 437964562Sgshapiro by Todd C. Miller of Courtesan Consulting. 438064562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 438164562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 438264562Sgshapiro Institute for Global Communications. 438364562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 438464562Sgshapiro alias file(s) if the -f option is not used. Patch from 438564562Sgshapiro John Beck of Sun Microsystems. 438664562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 438764562Sgshapiro configuration file to use for finding alias file(s). Patch 438864562Sgshapiro from John Beck of Sun Microsystems. 438964562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 439064562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 439164562Sgshapiro of the Institute for Global Communications. 439264562Sgshapiro SMRSH: Update README for the new Build system. From Tim Pierce 439364562Sgshapiro of RootsWeb Genealogical Data Cooperative. 439464562Sgshapiro VACATION: Added vacation auto-responder to sendmail distribution. 439564562Sgshapiro LIBSMDB: Added abstracted database library. Works with Berkeley 439664562Sgshapiro DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM. 439764562Sgshapiro Changed Files: 439864562Sgshapiro The Build script in the various program subdirectories are 439964562Sgshapiro no longer symbolic links. They are now scripts 440064562Sgshapiro which execute the actual Build script in 440164562Sgshapiro devtools/bin. 440264562Sgshapiro All the manual pages are now written against -man and not 440364562Sgshapiro -mandoc as they were previously. 440464562Sgshapiro Add a simple Makefile to every directory so make instead 440564562Sgshapiro of Build will work (unless parameters are 440664562Sgshapiro required for Build). 440764562Sgshapiro New Directories: 440864562Sgshapiro devtools/M4/UNIX 440964562Sgshapiro include 441064562Sgshapiro libmilter 441164562Sgshapiro libsmdb 441264562Sgshapiro libsmutil 441364562Sgshapiro vacation 441464562Sgshapiro Renamed Directories: 441564562Sgshapiro BuildTools => devtools 441664562Sgshapiro src => sendmail 441764562Sgshapiro Deleted Files: 441864562Sgshapiro cf/m4/nullrelay.m4 441964562Sgshapiro devtools/OS/Linux.ppc 442064562Sgshapiro devtools/OS/ReliantUNIX 442164562Sgshapiro devtools/OS/SINIX 442264562Sgshapiro sendmail/ldap_map.h 442364562Sgshapiro New Files: 442464562Sgshapiro INSTALL 442564562Sgshapiro PGPKEYS 442664562Sgshapiro cf/cf/generic-linux.cf 442764562Sgshapiro cf/cf/generic-linux.mc 442864562Sgshapiro cf/feature/delay_checks.m4 442964562Sgshapiro cf/feature/dnsbl.m4 443064562Sgshapiro cf/feature/generics_entire_domain.m4 443164562Sgshapiro cf/feature/no_default_msa.m4 443264562Sgshapiro cf/feature/relay_mail_from.m4 443364562Sgshapiro cf/feature/virtuser_entire_domain.m4 443464562Sgshapiro cf/mailer/qpage.m4 443564562Sgshapiro cf/ostype/bsdi.m4 443664562Sgshapiro cf/ostype/hpux11.m4 443764562Sgshapiro cf/ostype/openbsd.m4 443864562Sgshapiro contrib/bounce-resender.pl 443964562Sgshapiro contrib/domainmap.m4 444064562Sgshapiro contrib/qtool.8 444164562Sgshapiro contrib/qtool.pl 444264562Sgshapiro devtools/M4/depend/AIX.m4 444364562Sgshapiro devtools/M4/list.m4 444464562Sgshapiro devtools/M4/string.m4 444564562Sgshapiro devtools/M4/subst_ext.m4 444664562Sgshapiro devtools/M4/switch.m4 444764562Sgshapiro devtools/OS/Darwin 444864562Sgshapiro devtools/OS/GNU 444964562Sgshapiro devtools/OS/SINIX.5.43 445064562Sgshapiro devtools/OS/SINIX.5.44 445164562Sgshapiro devtools/OS/m88k 445264562Sgshapiro devtools/bin/find_in_path.sh 445364562Sgshapiro mail.local/Makefile 445464562Sgshapiro mailstats/Makefile 445564562Sgshapiro makemap/Makefile 445664562Sgshapiro praliases/Makefile 445764562Sgshapiro rmail/Makefile 445864562Sgshapiro sendmail/Makefile 445964562Sgshapiro sendmail/bf.h 446064562Sgshapiro sendmail/bf_portable.c 446164562Sgshapiro sendmail/bf_portable.h 446264562Sgshapiro sendmail/bf_torek.c 446364562Sgshapiro sendmail/bf_torek.h 446464562Sgshapiro sendmail/shmticklib.c 446564562Sgshapiro sendmail/statusd_shm.h 446664562Sgshapiro sendmail/timers.c 446764562Sgshapiro sendmail/timers.h 446864562Sgshapiro smrsh/Makefile 446964562Sgshapiro vacation/Makefile 447064562Sgshapiro Renamed Files: 447164562Sgshapiro cf/ostype/gnuhurd.m4 => cf/ostype/gnu.m4 447264562Sgshapiro sendmail/cdefs.h => include/sendmail/cdefs.h 447364562Sgshapiro sendmail/sendmail.hf => sendmail/helpfile 447464562Sgshapiro sendmail/mailstats.h => include/sendmail/mailstats.h 447564562Sgshapiro sendmail/pathnames.h => include/sendmail/pathnames.h 447664562Sgshapiro sendmail/safefile.c => libsmutil/safefile.c 447764562Sgshapiro sendmail/snprintf.c => libsmutil/snprintf.c 447864562Sgshapiro sendmail/useful.h => include/sendmail/useful.h 447964562Sgshapiro cf/ostype/solaris2.m4 => cf/ostype/solaris2.pre5.m4 448064562Sgshapiro Copied Files: 448164562Sgshapiro cf/ostype/solaris2.ml.m4 => cf/ostype/solaris2.m4 448264562Sgshapiro 448364562Sgshapiro8.9.3/8.9.3 1999/02/04 448443730Speter SECURITY: Limit message headers to a maximum of 32K bytes (total 448543730Speter of all headers in a single message) to prevent a denial of 448643730Speter service attack.

Watson Research. 489538032Speter DSN success bounces generated from an invocation of sendmail -t 489638032Speter would be sent to both the sender and MAILER-DAEMON. 489738032Speter Problem noted by Claus Assmann of 489838032Speter Christian-Albrechts-University of Kiel. 489938032Speter Avoid "Error 0" messages on delivery mailers which exit with a 490038032Speter valid exit value such as EX_NOPERM. Fix from Andreas Luik 490138032Speter of ISA Informationssysteme GmbH. 490238032Speter Tokenize $&x expansions on right hand side of rules. This eliminates 490338032Speter the need to use tricks like $(dequote "" $&{client_name} $) 490438032Speter to cause the ${client_name} macro to be properly tokenized. 490538032Speter Add the MaxRecipientsPerMessage option: this limits the number of 490638032Speter recipients that will be accepted in a single SMTP 490738032Speter transaction. After this number is reached, sendmail 490838032Speter starts returning "452 Too many recipients" to all RCPT 490938032Speter commands. This can be used to limit the number of recipients 491038032Speter per envelope (in particular, to discourage use of the server 491138032Speter for spamming). Note: a better approach is to restrict 491238032Speter relaying entirely. 491338032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 491438032Speter to ldapx map and added timeout for ldap_open call to 491538032Speter avoid hanging sendmail in the event of hung LDAP servers. 491638032Speter Patch from Booker Bense of Stanford University. 491738032Speter Allow multiple -qI, -qR, or -qS queue run limiters. For example, 491838032Speter '-qRfoo -qRbar' would deliver mail to recipients with foo or 491938032Speter bar in their address. Patch from Allan E Johannesen of 492038032Speter Worcester Polytechnic Institute. 492138032Speter The bestmx map will now return a list of the MX servers for a host if 492238032Speter passed a column delimiter via the -z map flag. This can be 492338032Speter used to check if the server is an MX server for the recipient 492438032Speter of a message. This can be used to help prevent relaying. 492538032Speter Patch from Mitchell Blank Jr of Exec-PC. 492638032Speter Mark failures for the *file* mailer and return bounce messages to the 492738032Speter sender for those failures. 492838032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 492938032Speter preserving the TZ environment variable until TimeZoneSpec 493038032Speter has been determined. Problem noted by Ralf Hildebrandt of 493138032Speter Technical University of Braunschweig. Patch from Per Hedeland 493238032Speter of Ericsson. 493338032Speter Print test input in address test mode when input is not from the tty 493464562Sgshapiro when the -v flag is given (i.e., sendmail -bt -v) to make 493538032Speter output easier to decipher. Problem noted by Aidan Nichol 493638032Speter of Procter & Gamble. 493738032Speter The LDAP map -s flag was not properly parsed and the error message 493864562Sgshapiro given included the remainder of the arguments instead of 493938032Speter solely the argument in error. Problem noted by Aidan Nichol 494038032Speter of Procter & Gamble. 494138032Speter New DontBlameSendmail option. This option allows administrators to 494238032Speter bypass some of sendmail's file security checks at the expense 494338032Speter of system security. This should only be used if you are 494438032Speter absolutely sure you know the consequences. The available 494538032Speter DontBlameSendmail options are: 494638032Speter Safe 494738032Speter AssumeSafeChown 494838032Speter ClassFileInUnsafeDirPath 494938032Speter ErrorHeaderInUnsafeDirPath 495038032Speter GroupWritableDirPathSafe 495138032Speter GroupWritableForwardFileSafe 495238032Speter GroupWritableIncludeFileSafe 495338032Speter GroupWritableAliasFile 495438032Speter HelpFileinUnsafeDirPath 495538032Speter WorldWritableAliasFile 495638032Speter ForwardFileInGroupWritableDirPath 495738032Speter IncludeFileInGroupWritableDirPath 495838032Speter ForwardFileInUnsafeDirPath 495938032Speter IncludeFileInUnsafeDirPath 496038032Speter ForwardFileInUnsafeDirPathSafe 496138032Speter IncludeFileInUnsafeDirPathSafe 496238032Speter MapInUnsafeDirPath 496338032Speter LinkedAliasFileInWritableDir 496438032Speter LinkedClassFileInWritableDir 496538032Speter LinkedForwardFileInWritableDir 496638032Speter LinkedIncludeFileInWritableDir 496738032Speter LinkedMapInWritableDir 496838032Speter LinkedServiceSwitchFileInWritableDir 496938032Speter FileDeliveryToHardLink 497038032Speter FileDeliveryToSymLink 497138032Speter WriteMapToHardLink 497238032Speter WriteMapToSymLink 497338032Speter WriteStatsToHardLink 497438032Speter WriteStatsToSymLink 497538032Speter RunProgramInUnsafeDirPath 497638032Speter RunWritableProgram 497738032Speter New DontProbeInterfaces option to turn off the inclusion of all the 497838032Speter interface names in $=w on startup. In particular, if you 497938032Speter have lots of virtual interfaces, this option will speed up 498038032Speter startup. However, unless you make other arrangements, mail 498138032Speter sent to those addresses will be bounced. 498238032Speter Automatically create alias databases if they don't exist and 498338032Speter AutoRebuildAliases is set. 498438032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 498538032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 498638032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 498738032Speter When determining the client host name ($&{client_name} macro), do 498838032Speter a forward (A) DNS lookup on the result of the PTR lookup 498938032Speter and compare results. If they differ or if the PTR lookup 499038032Speter fails, &{client_name} will contain the IP address 499164562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 499238032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 499338032Speter (i.e, it is like -ax for the temporary failure case, in 499438032Speter contrast to the success case). 499538032Speter New syntax to do limited checking of header syntax. A config line 499638032Speter of the form: 499738032Speter HHeader: $>Ruleset 499838032Speter causes the indicated Ruleset to be invoked on the Header 499938032Speter when read. This ruleset works like the check_* rulesets -- 500038032Speter that is, it can reject mail on the basis of the contents. 500138032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 500238032Speter from hiding their connection information in Received: 500338032Speter headers. 500438032Speter When SingleThreadDelivery is active, deliveries to locked hosts 500538032Speter are skipped. This will cause the delivering process to 500638032Speter try the next MX host or queue the message if no other MX 500738032Speter hosts are available. Suggested by Alexander Litvin. 500838032Speter The [FILE] mailer type now delivers to the file specified in the 500938032Speter A= equate of the mailer definition instead of $u. It also 501038032Speter obeys all of the F= mailer flags such as the MIME 501138032Speter 7/8 bit conversion flags. This is useful for defining 501238032Speter a mailer which delivers to the same file regardless of the 501364562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 501438032Speter Do not assume the identity of a remote connection is root@localhost 501538032Speter if the remote connection closes the socket before the 501638032Speter remote identity can be queried. 501738032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 501838032Speter Some mailers, including procmail, require that the real 501938032Speter uid is left unchanged by sendmail. Problem noted by Per 502038032Speter Hedeland of Ericsson. 502138032Speter No longer is the src/obj*/Makefile selected from a large list -- it 502238032Speter is now generated using the information in BuildTools/OS/ -- 502338032Speter some of the details are determined dynamically via 502438032Speter BuildTools/bin/configure.sh. 502538032Speter The other programs in the sendmail distribution -- mail.local, 502638032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 502738032Speter the new Build method which creates an operating system 502838032Speter specific Makefile using the information in BuildTools. 502938032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 503038032Speter a failure on one message won't affect future messages to the 503138032Speter same host). This is necessary if the remote host sends 503238032Speter a 451 error if the domain of the sender does not resolve 503338032Speter as is common in anti-spam configurations. Problem noted 503438032Speter by Mitchell Blank Jr of Exec-PC. 503538032Speter New "discard" mailer for check_* rulesets and header checking 503638032Speter rulesets. If one of the above rulesets resolves to the 503738032Speter $#discard mailer, the commands will be accepted but the 503838032Speter message will be completely discarded after it is accepting. 503938032Speter This means that even if only one of the recipients 504038032Speter resolves to the $#discard mailer, none of the recipients 504138032Speter will receive the mail. Suggested by Brian Kantor. 504238032Speter All but the last cloned envelope of a split envelope were queued 504338032Speter instead of being delivered.

Patch from Kari Hurtta of the Finnish 522738032Speter Meteorological Institute. 522838032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 522938032Speter daemon since DEC's /bin/mail will drop the envelope 523038032Speter sender if run as mailnull. See the Digital UNIX section 523138032Speter of src/README for more information. Problem noted by 523238032Speter Kari Hurtta of the Finnish Meteorological Institute. 523338032Speter CONFIG: .cf files are now stored in the same directory with the 523438032Speter .mc files instead of in the obj directory. 523564562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 523638032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 523738032Speter setting SingleLineFromHeader, AllowBogusHELO, and 523838032Speter MustQuoteChars respectively. 523938032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.

Problem noted by Kari Hurtta of the Finnish 535738032Speter Meteorological Institute. 535838032Speter If /usr/tmp/dead.letter already existed, sendmail could not 535938032Speter add additional bounces to it. Problem noted by Thomas J. 536038032Speter Arseneault of SRI International. 536138032Speter If an SMTP mailer used a non-standard port number for the outgoing 536238032Speter connection, it would be displayed incorrectly in verbose mode. 536338032Speter Problem noted by John Kennedy of Cal State University, Chico. 536438032Speter Log the ETRN parameter specified by the client before altering them 536538032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 536638032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 536738032Speter User unknown with bogus delay= values. Change them to log 536838032Speter the same as compliant addresses. Problem noted by Kari E. 536938032Speter Hurtta of the Finnish Meteorological Institute. 537038032Speter Ignore the debug resolver option unless using sendmail debug trace 537138032Speter option for resolver. Problem noted by Greg Nichols of Wind 537238032Speter River Systems. 537338032Speter If SingleThreadDelivery was enabled and the remote server returned a 537438032Speter protocol error on the DATA command, the connection would be 537538032Speter closed but the persistent host status file would not be 537638032Speter unlocked so other sendmail processes could not deliver to 537738032Speter that host. Problem noted by Peter Wemm of DIALix. 537838032Speter If queueing up a message due to an expensive mailer, don't increment 537938032Speter the number of delivery attempts or set the last delivery 538038032Speter attempt time so the message will be delivered on the next 538138032Speter queue run regardless of MinQueueAge. Problem noted by 538238032Speter Brian J. Coan of the Institute for Global Communications. 538338032Speter Authentication warnings of "Processed from queue _directory_" and 538438032Speter "Processed by _username_ with -C _filename_" would be logged 538538032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 538638032Speter of the Finnish Meteorological Institute. 538738032Speter Use a better heuristic for detecting GDBM. 538838032Speter Log null connections on dropped connections. Problem noted by 538938032Speter Jon Lewis of Florida Digital Turnpike. 539038032Speter If class dbm maps are rebuilt, sendmail will now detect this and 539138032Speter reopen the map. Previously, they could give stale 539238032Speter results during a single message processing (but would 539338032Speter recover when the next message was received). Fix from 539438032Speter Joe Pruett of Q7 Enterprises. 539538032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 539638032Speter requests. Problem noted by Kari E. Hurtta of the 539738032Speter Finnish Meteorological Institute. 539838032Speter Do not send a bounce message back to the sender regarding bad 539938032Speter recipients if the SMTP connection is dropped before the 540038032Speter message is accepted. Problem noted by Kari E. Hurtta of the 540138032Speter Finnish Meteorological Institute. 540238032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 540338032Speter sendmail via a UNIX pipe. This will allow rulesets using 540438032Speter $&{client_name} to process without sending the string through 540538032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 540638032Speter A combination of deferred delivery mode, a double bounce situation, 540738032Speter and the inability to save a bounce message to 540838032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 540938032Speter to postmaster but not remove the offending envelope from the 541038032Speter queue causing it to create a new bounce message each time the 541138032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 541238032Speter Associates. 541338032Speter Remove newlines from hostname information returned via DNS. There are 541438032Speter no known security implications of newlines in hostnames as 541538032Speter sendmail filters newlines in all vital areas; however, this 541638032Speter could cause confusing error messages. 541738032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 541838032Speter rejected if any of the specified addresses were bad. This 541938032Speter behavior was modified to only reject the bad addresses and not 542038032Speter the entire message. Problem noted by Jozsef Hollosi of 542138032Speter SuperNet, Inc. 542238032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 542338032Speter Bryan Costales of InfoBeat, Inc. 542438032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 542538032Speter mailers. Problem noted by Kari E. Hurtta of the 542638032Speter Finnish Meteorological Institute. 542738032Speter An error in calculating the available space in the list of addresses 542838032Speter for logging deliveries could cause an address to be silently 542938032Speter dropped. 543038032Speter Include the initial user environment if sendmail is restarted via 543138032Speter a HUP signal. This will give room for the process title. 543238032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 543338032Speter Mail could be delivered without a body if the machine does not 543438032Speter support flock locking and runs out of processes during 543538032Speter delivery. Fix from Chuck Lever of the University of Michigan. 543638032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 543738032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 543838032Speter Institute. 543938032Speter Make sure non-rebuildable database maps are opened before the 544064562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 544138032Speter are needed for verifying the left hand side of the aliases. 544238032Speter Problem noted by Lloyd Parkes of Victoria University. 544338032Speter Make sure sender RFC822 source route addresses are alias expanded for 544438032Speter bounce messages. Problem noted by Juergen Georgi of 544538032Speter RUS University of Stuttgart. 544638032Speter Minor lint fixes. 544738032Speter Return a temporary error instead of a permanent error if an LDAP map 544838032Speter search returns an error. This will allow sequenced maps which 544938032Speter use other LDAP servers to be checked. Fix from Booker Bense 545038032Speter of Stanford University. 545138032Speter When automatically converting from quoted printable to 8bit text do 545238032Speter not pad bare linefeeds with a space. Problem noted by Theo 545338032Speter Nolte of the University of Technology Aachen, Germany. 545438032Speter Portability: 545538032Speter Non-standard C compilers may have had a problem compiling 545638032Speter conf.c due to a standard C external declaration of 545738032Speter setproctitle(). Problem noted by Ted Roberts of 545838032Speter Electronic Data Systems. 545938032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 546038032Speter Jagielski of jaguNET Access Services. 546138032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 546238032Speter Digital UNIX: Digital UNIX (and possibly others) moves 546338032Speter loader environment variables into the loader memory 546438032Speter area. If one of these environment variables (such as 546538032Speter LD_LIBRARY_PATH) was the last environment variable, 546638032Speter an invalid memory address would be used by the process 546738032Speter title routine causing memory corruption. Problem 546838032Speter noted by Sam Hartman of Mesa Internet Systems. 546938032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 547038032Speter chownsafe() to always return 0 even if the OS does 547138032Speter not permit file giveaways. Problem noted by 547238032Speter Yasutaka Sumi of The University of Tokyo. 547364562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 547438032Speter Gerald Rinske of Siemens Business Services VAS. 547538032Speter Linux: Pad process title with NULLs. Problem noted by 547638032Speter Jon Lewis of Florida Digital Turnpike. 547738032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 547838032Speter incorrect value for the number of interfaces. 547938032Speter Problem noted by Chris Loelke of JetStream Internet 548038032Speter Services. 548138032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 548238032Speter Rinske of Siemens Business Services VAS. 548338032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 548438032Speter used on a Solaris machine. Problem noted by 548538032Speter Stephen Ma of Jtec Pty Limited. 548638032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 548738032Speter Services VAS. 548838032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 548938032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 549038032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 549138032Speter Ericsson. 549238032Speter 549364562Sgshapiro8.8.7/8.8.7 1997/08/03 549438032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 549538032Speter an exclusive lock already set -- i.e., almost all systems 549638032Speter except 4.4-BSD derived systems), the initial attempt at 549738032Speter rebuilding aliases file if the database didn't already 549838032Speter exist would fail. Patch from Raymund Will of LST Software 549938032Speter GmbH. 550038032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 550138032Speter Problem noted by Fredrik J�nsson of the Royal Institute 550238032Speter of Technology, Stockholm. 550338032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 550438032Speter some environments could give "multiple definitions" for these 550538032Speter routines during compilation. If using TCP Wrappers, assume 550638032Speter that these routines are included as though they were in the 550738032Speter C library. Patch from Robert La Ferla. 550838032Speter When a NEWDB database map was rebuilt at the same time it was being 550938032Speter used by a queue run, the maps could be left locked for the 551038032Speter duration of the queue run, causing other processes to hang. 551138032Speter Problem noted by Kendall Libby of Shore.NET. 551238032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 551338032Speter mail was passed on without any recipient header. This could 551438032Speter cause problems downstream. Problem noted by Xander Jansen 551538032Speter of SURFnet ExpertiseCentrum. 551638032Speter Give error when GDBM is used with sendmail. GDBM's locking and 551738032Speter linking of the .dir and .pag files interferes with sendmail's 551838032Speter locking and security checks. Problems noted by Fyodor 551938032Speter Yarochkin of the Kyrgyz Republic FreeNet. 552038032Speter Don't fsync qf files if SuperSafe option is not set. 552138032Speter Avoid extra calls to gethostbyname for addresses for which a 552238032Speter gethostbyaddr found no value. Also, ignore any returns 552338032Speter from gethostbyaddr that look like a dotted quad. 552438032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 552538032Speter "may be forged", since at the network level we pretty much 552638032Speter have to assume that the information is good. 552738032Speter In some cases, errors during an SMTP session could leave files 552838032Speter open or locked. 552938032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 553090792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 553138032Speter errors during testing. 553238032Speter Errors in file locking of NEWDB maps had the incorrect file name 553338032Speter printed in the error message. 553438032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 553538032Speter missing parameter were issued, the EHLO behaved like a HELO. 553638032Speter Load limiting never kicked in for incoming SMTP transactions if the 553743730Speter DeliveryMode=background and any recipient was an alias or 553838032Speter had a .forward file. From Nik Conwell of Boston University. 553938032Speter On some non-Posix systems, the decision of whether chown(2) permits 554038032Speter file giveaway was undefined. From Tetsu Ushijima of the 554138032Speter Tokyo Institute of Technology. 554238032Speter Fix race condition that could cause the body of a message to be 554338032Speter lost (so only the header was delivered). This only occurs 554438032Speter on systems that do not use flock(2), and only when a queue 554538032Speter runner runs during a critical section in another message 554638032Speter delivery. Based on a patch from Steve Schweinhart of 554738032Speter Results Computing. 554838032Speter If a qf file was found in a mail queue directory that had a problem 554938032Speter (wrong ownership, bad format, etc.) and the file name was 555038032Speter exactly MAXQFNAME bytes long, then instead of being tried 555138032Speter once, it would be tried on every queue run. Problem noted 555238032Speter by Bryan Costales of Mercury Mail. 555338032Speter If the system supports an st_gen field in the status structure, 555438032Speter include it when reporting that a file has changed after open. 555538032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 555638032Speter This out to be checked as well as reported, since it is 555738032Speter theoretically possible for an attacker to remove a file after 555838032Speter it is opened and replace it with another file that has the 555938032Speter same i-number, but some filesystems (notably AFS) return 556038032Speter garbage in this field, and hence always look like the file 556138032Speter has changed. As a practical matter this is not a security 556238032Speter problem, since the files can be neither hard nor soft links, 556338032Speter and on no filesystem (that I am aware of) is it possible to 556438032Speter have two files on the same filesystem with the same i-number 556538032Speter simultaneously. 556638032Speter Delete the root Makefile from the distribution -- it is only for 556738032Speter use internally, and does not work at customer sites. 556838032Speter Fix botch that caused the second MAIL FROM: command in a single 556938032Speter transaction to clear the entire transaction. Problem 557038032Speter noted by John Kennedy of Cal State University, Chico. 557138032Speter Work properly on machines that have _PATH_VARTMP defined without 557238032Speter a trailing slash.

This makes it possible to create a root 565538032Speter owned file in an arbitrary directory by inserting the symlink 565638032Speter into a writable directory after the initial lstat(2) check 565738032Speter determined that the file did not exist. The only verified 565838032Speter example of a system having these odd semantics for O_EXCL 565938032Speter and symbolic links was HP-UX prior to version 9.07. Most 566038032Speter systems do not have the problem, since a exclusive create 566138032Speter of a file disallows symbolic links. Systems that have been 566238032Speter verified to NOT have the problem include AIX 3.x, *BSD, 566338032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 566438032Speter and Ultrix. This is a potential exposure on systems that 566538032Speter have this bug and which do not have a MAILER-DAEMON alias 566638032Speter pointing at a legitimate account, since this will cause old 566738032Speter mail to be dropped in /var/tmp/dead.letter. 566838032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 566938032Speter if maps or alias files are in world writable directories. 567038032Speter If your system has alias maps in writable directories, it 567138032Speter is potentially possible for an attacker to replace the .db 567238032Speter (or .dir and .pag) files by symbolic links pointing at 567338032Speter another database; this can be used either to expose 567438032Speter information (e.g., by pointing an alias file at /etc/spwd.db 567538032Speter and probing for accounts), or as a denial-of-service attack 567638032Speter (by trashing the password database). The fix disallows 567738032Speter symbolic links entirely when rebuilding alias files or on 567838032Speter maps that are in writable directories, and always warns on 567938032Speter writable directories; 8.9 will probably consider writable 568038032Speter directories to be fatal errors. This does not represent an 568138032Speter exposure on systems that have alias files in unwritable 568238032Speter system directories. 568338032Speter SECURITY: disallow .forward or :include: files that are links (hard 568438032Speter or soft) if the parent directory (or any directory in the 568538032Speter path) is writable by anyone other than the owner. This is 568638032Speter similar to the previous case for user files. This change 568738032Speter should not affect most systems, but is necessary to prevent 568838032Speter an attacker who can write the directory from pointing such 568938032Speter files at other files that are readable only by the owner. 569038032Speter SECURITY: Tighten safechown rules: many systems will say that they 569138032Speter have a safe (restricted to root) chown even on files that 569238032Speter are mounted from another system that allows owners to give 569338032Speter away files. The new rules are very strict, trusting file 569438032Speter ownership only in those few cases where the system has 569538032Speter been verified to be at least as paranoid as necessary. 569638032Speter However, it is possible to relax the rules to partially 569738032Speter trust the ownership if the directory path is not world or 569838032Speter group writable. This might allow someone who has a legitimate 569938032Speter :include: file (referenced directly from /etc/aliases) to 570038032Speter become another non-root user if the :include: file is in a 570138032Speter non-writable directory on an NFS-mounted filesystem where 570238032Speter the local system says that giveaway is denied but it is 570338032Speter actually permitted. I believe this to be a very small set 570438032Speter of cases. If in doubt, do not point :include: aliases at 570538032Speter NFS-mounted filesystems. 570638032Speter SECURITY: When setting a numeric group id using the RunAsUser option 570738032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 570838032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 570938032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 571038032Speter The user id was still set properly. Problem noted by Uli 571138032Speter Pralle of the Technical University of Berlin. 571238032Speter Save the initial gid set for use when checking for if the 571338032Speter PrivacyOptions=restrictmailq option is set. Problem reported 571438032Speter by Wolfgang Ley of DFN-CERT. 571538032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 571638032Speter failure on one message won't affect future messages to the 571738032Speter same host). 571838032Speter IP source route printing had an "off by one" error that would 571938032Speter affect any options that came after the route option. Patch 572038032Speter from Theo de Raadt. 572138032Speter The "Message is too large" error didn't successfully bounce the error 572238032Speter back to the sender. Problem reported by Stephen More of 572338032Speter PSI; patch from Gregory Neil Shapiro of WPI. 572438032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 572538032Speter of 5.1.3); it apparently gets used in multiple ways. 572638032Speter Suggested by John Myers of Portola Communications. 572738032Speter Fix possible extra null byte generated during collection if errors 572838032Speter occur at the beginning of the stream. Patch contributed by 572938032Speter Andrey A. Chernov and Gregory Neil Shapiro. 573038032Speter Code changes to avoid possible reentrant call of malloc/free within 573138032Speter a signal handler. Problem noted by John Beck of Sun 573238032Speter Microsystems. 573338032Speter Move map initialization to be earlier so that check_relay ruleset 573438032Speter will have the latest version of the map data. Problem noted 573538032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 573638032Speter If there are fatal errors during the collection phase (e.g., message 573738032Speter too large) don't send the bogus message. 573838032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 573938032Speter have errors and have owner- aliases. Problem noted by Michael 574038032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 574138032Speter Avoid null pointer dereference on illegal Boundary= parameters in 574238032Speter multipart/mixed Content-Type: header. Problem noted by 574338032Speter Richard Muirden of RMIT University. 574438032Speter Always print error messages during newaliases (-bi) even if the 574538032Speter ErrorMode is not set to "print". Fix from Gregory Neil 574638032Speter Shapiro. 574738032Speter Test mode could core dump if you did a /map lookup in an optional map 574838032Speter that could not be opened. Based on a fix from John Beck of 574938032Speter Sun Microsystems. 575038032Speter If DNS is misconfigured so that the last MX record tried points to 575138032Speter a host that does not have an A record, but other MX records 575238032Speter pointed to something reasonable, don't bounce the message 575338032Speter with a "host unknown" error. Note that this should really 575438032Speter be fixed in the zone file for the domain. Problem noted by 575538032Speter Joe Rhett of Navigist, Inc. 575638032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 575738032Speter the message as having been tried; otherwise the next queue 575838032Speter run will not realize that this is a second attempt and will 575938032Speter retry immediately. Problem noted by Bryan Costales of 576038032Speter Mercury Mail. 576138032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 576238032Speter will be run until the later setting of the clock is reached. 576338032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 576438032Speter Morgan Stanley. 576538032Speter If the load average rises above the cutoff threshold (above which 576638032Speter sendmail will not process the queue at all) during a queue 576738032Speter run, abort the queue run immediately. Problem noted by 576838032Speter Bryan Costales of Mercury Mail. 576938032Speter The variable queue processing algorithm (based on the message size, 577038032Speter number of recipients, message precedence, and job age) was 577138032Speter non-functional -- either the entire queue was processed or 577238032Speter none of the queue was processed. The updated algorithm 577338032Speter does no queue run if a single recipient zero size job will 577438032Speter not be run. 577538032Speter If there is a fatal ("panic") message that will cause sendmail to 577638032Speter die immediately, never hold the error message for future 577738032Speter printing. 577838032Speter Force ErrorMode=print in -bt mode so that all errors are printed 577938032Speter regardless of the setting of the ErrorMode option in the 578038032Speter configuration file. Patch from Gregory Neil Shapiro. 578138032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 578238032Speter routine available in one of the libraries. Use it in conf.h. 578338032Speter The -m (match only) flag now works on host class maps. 578438032Speter If class hash or btree maps are rebuilt, sendmail will now detect 578538032Speter this and reopen the map. Previously, they could give 578638032Speter erroneous results during a single message processing 578738032Speter (but would recover when the next message was received). 578838032Speter Don't delete zero length queue files when doing queue runs until the 578938032Speter files are at least ten minutes old. This avoids a potential 579038032Speter race condition: the creator creates the qf file, getting back 579138032Speter a file descriptor. The queue runner locks it and deletes it 579238032Speter because it is zero length. The creator then writes the 579338032Speter descriptor that is now for a disconnected file, and the 579438032Speter job goes away. Based on a suggestion by Bryan Costales. 579538032Speter When determining the "validated" host name ($_ macro), do a forward 579638032Speter (A) DNS lookup on the result of the PTR lookup and compare 579738032Speter results. If they differ or if the PTR lookup fails, tag the 579838032Speter address as "may be forged". 579938032Speter Log null connections (i.e., hosts that connect but do not do any 580038032Speter substantive activity on the connection before disconnecting; 580138032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 580238032Speter Always permit "writes" to /dev/null regardless of the link count. 580338032Speter This is safe because /dev/null is special cased, and no open 580438032Speter or write is ever actually attempted. Patch from Villy Kruse 580538032Speter of TwinCom. 580638032Speter If a message cannot be sent because of a 552 (exceeded storage 580738032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 580838032Speter was given, don't return the body in the bounce, since there 580938032Speter is a very good chance that the message will double-bounce. 581038032Speter Fix possible line truncation if a quoted-printable had an =00 escape 581138032Speter in the body. Problem noted by Charles Karney of the Princeton 581238032Speter Plasma Physics Laboratory. 581338032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 581438032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 581538032Speter Institute. 581638032Speter The MaxDaemonChildren option wasn't applying to queue runs as 581738032Speter documented. Note that this increases the potential denial 581838032Speter of service problems with this option: an attacker can 581938032Speter connect many times, and thereby lock out queue runs as well 582038032Speter as incoming connections. If you use this option, you should 582138032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 582238032Speter to avoid this attack. Failure to limit noted by Matthew 582338032Speter Dillon of BEST Internet Communications. 582438032Speter Always give a message in newaliases if alias files cannot be 582538032Speter opened instead of failing silently. Suggested by Gregory 582638032Speter Neil Shapiro. This change makes the code match the O'Reilly 582738032Speter book (2nd edition). 582838032Speter Some older versions of the resolver could return with h_errno == -1 582938032Speter if no name server could be reached, causing mail to bounce 583038032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 583138032Speter John Beck of SunSoft. 583238032Speter If a :include: file is owned by a user that does not have an entry 583338032Speter in the passwd file, sendmail could dereference a null pointer. 583438032Speter Problem noted by Satish Mynam of Sun Microsystems. 583538032Speter Take precautions to make sure that the SMTP protocol cannot get out 583638032Speter of sync if (for example) an alias file cannot be opened. 583738032Speter Fix a possible race condition that can cause a SIGALRM to come in 583838032Speter immediately after a SIGHUP, causing the new sendmail to die. 583938032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 584038032Speter from Villy Kruse of TwinCom. 584138032Speter Ignore improperly formatted SMTP reply codes. Previously these were 584238032Speter partially processed, which could cause confusing error 584338032Speter returns. 584438032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 584538032Speter on some architectures. 584638032Speter Portability: 584738032Speter A/UX: from Jim Jagielski of NASA/GSFC. 584838032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 584938032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 585038032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 585138032Speter defined. Problem reported by A Sun of the University 585238032Speter of Washington. 585338032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 585438032Speter the system rather than guessing at compile time. 585538032Speter Patch contributed by John Beck of Sun Microsystems. 585638032Speter Intel Paragon: from Wendy Lin of Purdue University. 585738032Speter GNU Hurd: from Miles Bader of the GNU project. 585838032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 585938032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 586038032Speter Unfortunately releasing them opens a race condition, 586138032Speter but there appears to be no fix for this.

Patch from Philip 588738032Speter Guenther of Gustavus Adolphus College. 588838032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 588938032Speter rules are the same as for aliasing. Based on a patch from 589038032Speter Gregory Neil Shapiro. 589138032Speter CONFIG: Break up parsing rules into several pieces; this should 589238032Speter have no functional change in this release, but makes it 589338032Speter possible to have better anti-spam rulesets in the future. 589438032Speter CONFIG: Disallow double dots in host names to avoid having the 589538032Speter HostStatusDirectory store status under the wrong name. 589638032Speter In some cases this can be used as a denial-of-service attack. 589738032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 589838032Speter Gregory Neil Shapiro. 589938032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 590038032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 590138032Speter don't include From_, and convert to 8-bit). Suggestions 590238032Speter from Kimmo Suominen and Roderick Schertler. 590364562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 590438032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 590538032Speter was specified, even when it wasn't. 590638032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 590738032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 590838032Speter "slip in" a symbolic link between the lstat(2) call and the 590938032Speter exclusive open. This is only a problem on System V derived 591038032Speter systems that allow an exclusive create on files that are 591138032Speter symbolic links pointing nowhere. 591238032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 591338032Speter not reset back to root, which on some systems would cause 591438032Speter later mailboxes to fail. Also, any partial message would 591538032Speter not be truncated, which could result in repeated deliveries. 591638032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 591738032Speter developers). 591838032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 591938032Speter change to the sendmail map code was made in 8.8.3. Problem 592038032Speter noted by Gregory Neil Shapiro. 592138032Speter MAKEMAP: Give warnings on file problems such as map files that are 592290792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 592338032Speter often run as root and hence has the potential for the same 592438032Speter sorts of problems as alias rebuilds. 592538032Speter MAKEMAP: Change compilation so that it will link properly on 592638032Speter NEXTSTEP. 592738032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 592838032Speter Accept an optional list of arguments following the server 592938032Speter name for the ETRN arguments to use (instead of $=w).

From Christian von Roques via 593138032Speter John Beck of Sun Microsystems. 593238032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 593338032Speter Perl script converts GECOS information in the /etc/passwd 593438032Speter file into aliases, allowing for faster access to full name 593538032Speter lookups; it is also clever about adding aliases (to root) 593638032Speter for system accounts. 593738032Speter NEW FILES: 593838032Speter src/safefile.c 593938032Speter cf/ostype/gnuhurd.m4 594038032Speter cf/ostype/irix6.m4 594138032Speter contrib/passwd-to-alias.pl 594238032Speter src/Makefiles/Makefile.IRIX64.6.1 594338032Speter src/Makefiles/Makefile.IRIX64.6.x 594438032Speter RENAMED FILES: 594538032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 594638032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 594738032Speter 594864562Sgshapiro8.8.5/8.8.5 1997/01/21 594938032Speter SECURITY: Clear out group list during startup. Without this, sendmail 595038032Speter will continue to run with the group permissions of the caller, 595138032Speter even if RunAsUser is specified. 595238032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 595338032Speter to any known attack, but it's best to be conservative. 595438032Speter Suggested by Peter Wemm of DIALix. 595538032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 595638032Speter security implications. Patch from Alex Garthwaite of the 595738032Speter University of Pennsylvania. 595838032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 595938032Speter would truncate the address after "Full". Although the -f 596038032Speter syntax is incorrect (since it is in the envelope, it 596138032Speter shouldn't have comments and full names), the failure mode 596238032Speter was unnecessarily awful. 596338032Speter Fix a possible null pointer dereference when converting 8-bit data 596438032Speter to a 7-bit format. Problem noted by Jim Hutchins of 596538032Speter Sandia National Labs and David James of British Telecom. 596638032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 596738032Speter runs. Although this really shouldn't be used (F=9 is for 596838032Speter final delivery only, and using it on an SMTP mailer makes 596938032Speter it possible for a message to be converted from 8->7->8->7 597038032Speter bits several times), it shouldn't have failed with a syserr. 597138032Speter Problem noted by Eric Hagberg of Morgan Stanley. 597238032Speter _Really_ fix the multiple :maildrop code in the user database 597338032Speter module. Patch from Roy Mongiovi of Georgia Tech. 597438032Speter Let F lines in the configuration file actually read root-only 597538032Speter files if the configuration file is safe. Based on a 597638032Speter patch from Keith Reynolds of SCO. 597738032Speter ETRN followed by QUIT would hold the connection open until the queue 597838032Speter run completed. Problem noted by Truck Lewis of TDK 597938032Speter Semiconductor Corp. 598038032Speter It turns out that despite the documentation, the TCP wrappers library 598138032Speter does _not_ log rejected connections. Do the logging ourselves. 598238032Speter Problem noted by Fletcher Mattox of the University of Texas 598338032Speter at Austin. 598438032Speter If sendmail finds a qf file in its queue directory that is an unknown 598538032Speter version (e.g., when backing out to an old version), the 598638032Speter error is reported on every queue run. Change it to only 598738032Speter give the error once (and rename the qf => Qf). Patch from 598838032Speter William A. Gianopoulos of Raytheon Company. 598938032Speter Start a new session when doing background delivery; currently it 599038032Speter ignored signals but didn't start a new signal, that caused 599138032Speter some problems if a background process tried to send mail 599238032Speter under certain circumstances. Problem noted by Eric Hagberg 599338032Speter of Morgan Stanley; fix from Kari Hurtta. 599438032Speter Simplify test for skipping a queue run to just check if the current 599538032Speter load average is >= the queueing load average. Previously 599638032Speter the check factored in some other parameters that caused it 599738032Speter to essentially never skip the queue run. Patch from Bryan 599838032Speter Costales. 599938032Speter If the SMTP server is running in "nullserver" mode (that is, it is 600038032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 600138032Speter (25) commands; this helps prevent a bad guy from putting 600238032Speter you into a tight loop as a denial-of-service attack. Based 600338032Speter on an e-mail conversation with Brad Knowles of AOL. 600438032Speter Slow down when too many "light weight" commands have been issued; 600538032Speter this helps prevent a class of denial-of-service attacks. 600638032Speter The current values and defaults are: 600738032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 600838032Speter MAXHELOCOMMANDS 3 HELO, EHLO 600938032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 601038032Speter MAXETRNCOMMANDS 8 ETRN 601138032Speter These will probably be configurable in a future release. 601238032Speter On systems that have uid_t typedefed to be an unsigned short, programs 601338032Speter that had the F=S flag and no U= equate would be invoked with 601438032Speter the real uid set to 65535 rather than being left unchanged. 601538032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 601638032Speter by Steve Hubert of the University of Washington, Seattle. 601738032Speter Mail that was Quoted-Printable encoded and had a soft line break on 601838032Speter the last line (i.e., an incomplete continuation) had the last 601938032Speter line dropped. Since this appears to be illegal it isn't 602038032Speter clear what to do with it, but flushing the last line seems 602138032Speter to be a better "fail soft" approach. Based on a patch from 602238032Speter Eric Hagberg. 602338032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 602438032Speter bogus HELO command still causes the "Polite people say HELO 602538032Speter first" error message. Problem pointed out by Chris Thomas 602638032Speter of UCLA; patch from John Beck of SunSoft. 602738032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 602871345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 602971345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 603071345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 603138032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 603238032Speter in a DATA transaction to be sticky; these can occur because 603338032Speter a message is too large, and smaller messages should still go 603438032Speter through. Problem noted by Matt Dillon of Best Internet 603538032Speter Communications. 603638032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 603738032Speter had been successfully delivered to the envelope sender. 603838032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 603938032Speter Gregory Neil Shapiro of WPI. 604038032Speter Give better diagnostics on long alias lines.

Problem noted by Ronan KERYELL 606838032Speter of Centre de Recherche en Informatique de l'�cole Nationale 606938032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 607038032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 607138032Speter such as LUSER_RELAY. This change permits the following 607238032Speter syntaxes: ``local:'' will send to the same user on the 607338032Speter local machine (e.g., in a mailertable entry for "host", 607438032Speter ``local:'' will cause an address addressed to user@host to 607538032Speter go to user on the local machone). ``local:user'' will send 607638032Speter to the named user on the local machine. ``local:user@host'' 607738032Speter is equivalent to ``local:user'' (the host is ignored). In 607838032Speter all cases, the original user@host is passed in $@ (i.e., the 607938032Speter detail information). Inspired by a report from Michael Fuhr. 608038032Speter CONFIG: Strip quotes from the first word of an "error:" host 608138032Speter indication. This lets you set (for example) the LUSER_RELAY 608238032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 608338032Speter of the \" so that the resulting string is properly quoted. 608438032Speter Problem noted by Gregory Neil Shapiro of WPI. 608538032Speter OP.ME: documentation was inconsistent about whether sendmail did a 608638032Speter NOOP or a RSET to probe the connection (it does a RSET). 608738032Speter Inconsistency noted by Deeran Peethamparam. 608838032Speter OP.ME: insert additional blank pages so it will print properly on 608938032Speter a duplex printer.

The solution is to disallow any 609638032Speter files that have hard links -- this will affect .forward, 609738032Speter :include:, and output files. Problem noted by Terry 609838032Speter Kyriacopoulos of Interlog Internet Services. As a 609938032Speter workaround, set UnsafeGroupWrites -- always a good idea. 610038032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 610138032Speter is, it is possible to do a denial-of-service attack on 610238032Speter MX hosts that rely on the use of the null MX list. There 610338032Speter is no danger if you have this option turned off (the default). 610438032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 610538032Speter unsafe. I know of no specific attack against this, although 610638032Speter a denial-of-service attack is probably possible, but in theory 610738032Speter you should not be able to safely tweak anything that affects 610838032Speter the permissions that are used when mail is delivered. 610938032Speter Purgestat could go into an infinite loop if one of the host status 611038032Speter directories somehow became empty. Problem noted by Roy 611138032Speter Mongiovi of Georgia Tech. 611238032Speter Processes got "lost" when counting children due to a race condition. 611338032Speter This caused "proc_list_probe: lost pid" messages to be logged. 611438032Speter Problem noted by several people. 611538032Speter On systems with System V SIGCLD child signal semantics (notably AIX 611638032Speter and HP-UX), mail transactions would print the message "451 611738032Speter SMTP-MAIL: lost child: No child processes". Problem noted 611838032Speter by several people. 611938032Speter Miscellaneous compiler warnings on picky compilers (or when setting 612038032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 612138032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 612238032Speter not be persistent between runs, since they are based on the 612338032Speter message rather than the host. Problem noted by Matt Dillon 612438032Speter of Best Internet Communications. 612538032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 612638032Speter of NCR (a.k.a., AT&T Global Information Solutions). 612738032Speter Avoid the possibility of having a child daemon run to completion 612838032Speter (including closing the SMTP socket) before the parent has 612938032Speter had a chance to close the socket; this can cause the parent 613038032Speter to hang for a long time waiting for the socket to drain. 613138032Speter Patch from Don Lewis of TDK Semiconductor. 613238032Speter If the fork() failed in a queue run, the queue runners would not be 613338032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 613438032Speter Some error conditions in ETRN could cause output without an SMTP 613538032Speter status code. Problem noted by Don Lewis. 613638032Speter Multiple :maildrop addresses in the user database didn't work properly. 613738032Speter Patch from Roy Mongiovi of Georgia Tech. 613838032Speter Add ".db" automatically onto any user database spec that does not 613938032Speter already have it; this is for consistency with makemap, the 614038032Speter K line, and the documentation. Inconsistency pointed out 614138032Speter by Roy Mongiovi. 614238032Speter Allow sendmail to be properly called in nohup mode. Patch from 614338032Speter Kyle Jones of UUNET. 614438032Speter Change ETRN to ignore but still update host status files; previously 614538032Speter it would ignore them and not save the updated status, which 614638032Speter caused stale information to be maintained. Based on a patch 614738032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 614838032Speter ETRN ignore the MinQueueAge option. 614938032Speter Patch long term host status to recover more gracefully from an empty 615038032Speter host status file condition. Patch from NAKAMURA Motonori 615138032Speter of Kyoto University. 615238032Speter Several patches to signal handling code to fix potential race 615338032Speter conditions from Don Lewis. 615438032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 615538032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 615638032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 615738032Speter compile flag; use NETINET instead. Solution based on a 615838032Speter patch from Bryan Costales. 615938032Speter PORTABILITY FIXES: 616038032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 616138032Speter /etc/security/passwd file when called as root.

Problem noted by Steve 620838032Speter Hubert of the University of Washington, Seattle. 620938032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 621038032Speter Problem reported by Tom Smith of Digital Equipment Corp. 621138032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 621238032Speter size PACKETSZ (512) is not sufficient for some nameserver 621338032Speter answers containing very many resource records. The resolver 621438032Speter may also switch to TCP and retry if it detects UDP packet 621538032Speter overflow. Also, allow for the fact that the resolver 621638032Speter routines res_query and res_search return the size of the 621738032Speter *un*truncated answer in case the supplied answer buffer it 621838032Speter not big enough to accommodate the entire answer. Patch from 621938032Speter Eric Wassenaar. 622038032Speter Improvements to MaxDaemonChildren code. If you think you have too 622138032Speter many children, probe the ones you have to verify that they 622238032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 622338032Speter Also, do this probe before growing the vector of children 622438032Speter pids; this previously caused the vector to grow indefinitely 622538032Speter due to a race condition. Problem reported by Kyle Jones of 622638032Speter UUNET. 622738032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 622838032Speter O_EXLOCK to zero; this fools the map compilation code into 622938032Speter thinking that it can avoid race conditions by locking on open. 623038032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 623138032Speter Leif Erlingsson of Data Lege. 623238032Speter Always call res_init() on startup (if compiled in, of course) to 623338032Speter allow the sendmail.cf file to tweak resolver flags; without 623438032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 623538032Speter Andrew Sun of Merrill Lynch. 623638032Speter Improvements to host status printing code. Suggested by Steve Hubert 623738032Speter of the University of Washington, Seattle. 623838032Speter Change MinQueueAge option processing to do the check for the job age 623938032Speter when reading the queue file, rather than at the end; this 624038032Speter avoids parsing the addresses, which can do DNS lookups. 624138032Speter Problem noted by John Beck of InReference, Inc. 624238032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 624338032Speter properly escaped. Problem noted by Peter Nilsson of the 624438032Speter University of Linkoping. 624538032Speter In some cases, sendmail would retain root permissions during queue 624638032Speter runs even if RunAsUser was set. Problem noted by Mark 624738032Speter Thomas of Mark G. Thomas Consulting. 624838032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 624938032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 625038032Speter the envelope, and the receiving SMTP server speaks DSN, then 625138032Speter the DSN would be both generated locally and propagated to the 625238032Speter other end. 625338032Speter The U= mailer field didn't correctly extract the group id if the 625438032Speter user id was numeric. Problem noted by Kenneth Herron of 625538032Speter MCI Telecommunications Communications. 625638032Speter If a message exceeded the fixed maximum size on input, the body of 625738032Speter the message was included in the bounce. Note that this did 625838032Speter not occur if it exceeded the maximum _output_ size. Problem 625938032Speter reported by Kyle Jones of UUNET. 626038032Speter PORTABILITY FIXES: 626138032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 626238032Speter AIX4 defines to use seteuid(2) instead, which 626338032Speter works on 4.1 as well as 4.2. Problem noted by 626438032Speter H�kan Lindholm of interAF, Sweden. 626538032Speter AIX4: use tzname[] vector to determine time zone name. 626638032Speter Patch from NAKAMURA Motonori of Kyoto University. 626738032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 626838032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 626938032Speter Solaris: kstat(3k) support for retrieving the load average. 627038032Speter This adds the LA_KSTAT definition for LA_TYPE. 627138032Speter The outline of the implementation was contributed 627238032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 627338032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 627438032Speter declaration of struct rusage at the top of conf.h; 627538032Speter change it to only be included if you are using gcc, 627638032Speter which is apparently the only compiler that requires 627738032Speter it in the first place. Problem noted by Jeff 627838032Speter Earickson of Colby College. 627938032Speter IRIX: don't default to using gcc. IRIX is a civilized 628038032Speter operating system that comes with a decent compiler 628138032Speter by default. Problem noted by Barry Bouwsma and 628238032Speter Kari Hurtta. 628338032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 628438032Speter consistency with other local mailers. Inconsistency 628538032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 628638032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 628738032Speter overhead) as part of the bestmx_is_local feature, the 628838032Speter domain part was dropped from the name. Patch from Steve 628938032Speter Hubert of the University of Washington, Seattle. 629038032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 629138032Speter end up being translated to the null host name, which would 629238032Speter return any entry in /etc/hosts that had a space at the end 629338032Speter of the line. Problem noted by Steve Hubert of the 629438032Speter University of Washington, Seattle. 629538032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 629638032Speter Polytechnic Institute. 629738032Speter MAKEMAP: tweak hash and btree parameters for better performance. 629838032Speter Patch from Matt Dillon of Best Internet Communications. 629938032Speter NEW FILES: 630038032Speter src/Makefiles/Makefile.Linux.ppc 630138032Speter cf/ostype/aix4.m4 630238032Speter cf/ostype/mklinux.m4 630338032Speter 630464562Sgshapiro8.8.2/8.8.2 1996/10/18 630538032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 630638032Speter changed the code but didn't fix the problem. 630738032Speter PORTABILITY FIXES: 630838032Speter Solaris: Don't use the system getusershell(3); it can 630938032Speter apparently corrupt the heap in some circumstances. 631038032Speter Problem found by Ken Pizzini of Spry, Inc. 631138032Speter OP.ME: document several mailer flags that were accidentally omitted 631238032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 631338032Speter CONFIG: no changes. 631438032Speter 631564562Sgshapiro8.8.1/8.8.1 1996/10/17 631638032Speter SECURITY: unset all environment variables that the resolver will 631738032Speter examine during queue runs and daemon mode. Problem noted 631838032Speter by Dan Bernstein of the University of Illinois at Chicago. 631938032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 632038032Speter message could overflow a buffer if it was converted back 632138032Speter to 8 bits. This caused core dumps and has the potential 632238032Speter for a remote attack. Problem first noted by Gregory Shapiro 632338032Speter of WPI. 632438032Speter Avoid duplicate deliveries of error messages on systems that don't 632538032Speter have flock(2) support. Patch from Motonori Nakamura of 632638032Speter Kyoto University. 632738032Speter Ignore null FallBackMX (V) options. If this option is null (as 632838032Speter opposed to undefined) it can cause "null signature" syserrs 632938032Speter on illegal host names. 633038032Speter If a Base64 encoded text/plain message has no trailing newline in 633138032Speter the encoded text, conversion back to 8 bits will drop the 633238032Speter final line. Problem noted by Pierre David. 633338032Speter If running with a RunAsUser, sendmail would give bogus "cannot 633438032Speter setuid" (or seteuid, or setreuid) messages on some systems. 633538032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 633638032Speter Always print error messages in -bv mode -- previously, -bv would 633738032Speter be absolutely silent on errors if the error mode was sent 633838032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 633938032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 634038032Speter term host status. This is necessary because it is common 634138032Speter to do this when you know a host has just come back up. 634238032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 634338032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 634438032Speter University of Leicester. 634538032Speter If a service (such as NIS) is specified as the last entry in the 634638032Speter service switch, but that service is not compiled in, sendmail 634738032Speter would return a temporary failure when an entry was not found 634838032Speter in the map. This caused the message to be queued instead of 634938032Speter bouncing immediately. Problem noted by Harry Edmon of the 635038032Speter University of Washington. 635138032Speter PORTABILITY FIXES: 635238032Speter Solaris 2.3 had compilation problems in conf.c. Several 635338032Speter people pointed this out. 635438032Speter NetBSD from Charles Hannum of MIT. 635538032Speter AIX4 improvements based on info from Steve Bauer of South 635638032Speter Dakota School of Mines & Technology. 635738032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 635838032Speter Patch from Gil Kloepfer Jr. 635938032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 636038032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 636138032Speter were also in $=w. Problem noted by Zoltan Basti of 636238032Speter Softec. 636338032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 636438032Speter on a patch from Eric Hagberg of Morgan Stanley. 636538032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 636638032Speter of Stanford via Robert La Ferla. 636738032Speter 636864562Sgshapiro8.8.0/8.8.0 1996/09/26 636938032Speter Under some circumstances, Bcc: headers would not be properly 637038032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 637138032Speter Log a warning if the sendmail daemon is invoked without a full 637238032Speter pathname, which prevents "kill -1" from working. I was 637338032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 637438032Speter Fix small buffer overflow. Since the data in this buffer was not 637538032Speter read externally, there was no security problem (and in fact 637638032Speter probably wouldn't really overflow on most compilers). Pointed 637738032Speter out by KIZU takashi of Osaka University. 637838032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 637938032Speter if a FallbackMXHost was specified in the configuration file 638038032Speter -- all mail would be sent to the fallback even if the original 638138032Speter host was accessible. Pointed out by Munenari Hirayama of 638238032Speter NSC (Japan). 638338032Speter A message that didn't terminate with a newline would (sometimes) not 638438032Speter have the trailing "." added properly in the SMTP dialogue, 638538032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 638638032Speter The DaemonPortOptions suboption to bind to a particular address was 638738032Speter incorrect and nonfunctional due to a misunderstanding of the 638838032Speter semantics of binding on a passive socket. Patch from 638938032Speter NIIBE Yutaka of Mitsubishi Research Institute. 639038032Speter Increase the number of MX hosts for a single name to 100 to better 639138032Speter handle the truly huge service providers such as AOL, which 639238032Speter has 13 at the moment (and climbing). In order to avoid 639338032Speter trashing memory, the buffer for all names has only been 639438032Speter slightly increased in size, to 12.8K from 10.2K -- this means 639538032Speter that if a single name had 100 MX records, the average size 639638032Speter of those records could not exceed 128 bytes. Requested by 639738032Speter Brad Knowles of America On Line. 639838032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 639938032Speter Urged by Dan Bernstein of U.C. Berkeley. 640038032Speter Print q_statdate and q_specificity in address structure debugging 640138032Speter printout. 640238032Speter Expand MCI structure flag bits for debugging output. 640338032Speter Support IPv6-style domain literals, which can have colons between 640438032Speter square braces. 640538032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 640638032Speter this is an attempt to track down a bug that one person seems 640738032Speter to be having (it may be a Solaris bug!). 640838032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 640938032Speter this caused the NOTIFY info to sometimes be lost. Problem 641038032Speter pointed out by Claus Assmann of the 641138032Speter Christian-Albrechts-University of Kiel. 641238032Speter The statistics gathered in the sendmail.st file were too high; in 641338032Speter some cases failures (e.g., user unknown or temporary failure) 641438032Speter would count as a delivery as far as the statistics were 641538032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 641638032Speter Systems that don't have flock() would not send split envelopes in 641738032Speter the initial run. Problem pointed out by Leonard Zubkoff of 641838032Speter Dandelion Digital. 641938032Speter Move buffer overflow checking -- these primarily involve distrusting 642038032Speter results that may come from NIS and DNS. 642138032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 642238032Speter include <paths.h> and hence had the wrong pathnames for a few 642338032Speter things like /var/tmp. Reported by Matthew Green. 642438032Speter Conditions were reversed for the Priority: header, resulting in all 642538032Speter values being interpreted as non-urgent except for non-urgent, 642638032Speter which was interpreted as normal. Patch from Bryan Costales. 642738032Speter The -o (optional) flag was being ignored on hash and btree maps 642838032Speter since 8.7.2. Fix from Bryan Costales. 642938032Speter Content-Types listed in class "q" will always be encoded as 643038032Speter Quoted-Printable (or more accurately, will never be encoded 643138032Speter as base64). The class can have primary types (e.g., "text") 643238032Speter or full types (e.g., "text/plain"). Based on a suggestion by 643338032Speter Marius Olafsson of the University of Iceland. 643438032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 643538032Speter dialogue) so it can be passed to programs in mailers. 643638032Speter Define ${bodytype} to be the body type (from the -B flag or the 643738032Speter BODY= ESMTP parameter) so it can be passed to programs in 643838032Speter mailers. 643938032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 644038032Speter flag is set in the mailer descriptor. Suggested by John 644138032Speter Myers of CMU. 644238032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 644338032Speter The command takes a host name; data for that host is 644438032Speter immediately (and asynchronously) flushed. Because this shares 644538032Speter the -qR implementation, other hosts may be attempted, but 644638032Speter there should be no security implications. Implementation 644738032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 644838032Speter Add three new command line flags to pass in DSN parameters: -V envid 644938032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 645038032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 645138032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 645238032Speter that the -N flag applies to all recipients; there is no way 645338032Speter to specify per-address notifications on the command line, 645438032Speter nor is there an equivalent for the ORCPT= per-address 645538032Speter parameter. 645638032Speter Restore LogLevel option to be safe (it can only be increased); 645738032Speter apparently I went into paranoid mode between 8.6 and 8.7 645838032Speter and made it unsafe. Pointed out by Dabe Murphy of the 645938032Speter University of Maryland. 646038032Speter New logging on log level 15: all SMTP traffic. Patches from 646138032Speter Andrew Gross of San Diego Supercomputer Center. 646238032Speter NetInfo property value searching code wasn't stopping when it found 646338032Speter a match. This was causing the wrong values to be found (and 646438032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 646538032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 646638032Speter out by Bill Wisner of Electronics for Imaging that you can't 646738032Speter use the bracket address form for the MAIL_HUB macro, since 646838032Speter that causes the brackets to remain in the envelope recipient 646938032Speter address used for delivery. The simple fix (stripping off the 647038032Speter brackets in the config file) breaks the use of IP literal 647138032Speter addresses. This flag will solve that problem. 647238032Speter Add MustQuoteChars option. This is a list of characters that must 647338032Speter be quoted if they are found in the phrase part of an address 647438032Speter (that is, the full name part). The characters @,;:\()[] are 647538032Speter always in this list and cannot be removed. The default is 647638032Speter this list plus . and ' to match RFC 822. 647738032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 647838032Speter that do not include a host name for back compatibility with 647938032Speter some stupid SMTP clients. Setting this violates RFC 1123 648038032Speter section 5.2.5. 648138032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 648238032Speter rejecting connections if it has more than this many 648338032Speter outstanding children accepting mail. Note that you may 648438032Speter see more processes than this because of outgoing mail; this 648538032Speter is for incoming connections only. 648638032Speter Add ConnectionRateThrottle option. If set to a positive value, the 648738032Speter number of incoming SMTP connections that will be permitted 648838032Speter in a single second is limited to this number. Connections are 648938032Speter not refused during this time, just deferred. The intent is to 649038032Speter flatten out demand so that load average limiting can kick in. 649138032Speter It is less radical than MaxDaemonChildren, which will stop 649238032Speter accepting connections even if all the connections are idle 649338032Speter (e.g., due to connection caching). 649438032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 649538032Speter specifies how long cached information about the state of a 649638032Speter host will be kept before they are considered stale and the 649738032Speter host is retried. If you are using persistent host status 649838032Speter (i.e., the HostStatusDirectory option is set) this will apply 649938032Speter between runs; otherwise, it applies only within a single queue 650038032Speter run and hence is useful only for hosts that have large queues 650138032Speter that take a very long time to run. 650238032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 650338032Speter into being a single line even if they had newlines in them 650438032Speter when read. This is to get around a botch in Lotus Notes. 650538032Speter Text class maps were totally broken -- if you ever retrieved the last 650638032Speter item in a table it would be truncated. Problem noted by 650738032Speter Gregory Neil Shapiro of WPI. 650838032Speter Extend the lines printed by the mailq command (== the -bp flag) when 650938032Speter -v is given to 120 characters; this allows more information 651038032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 651138032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 651238032Speter this was treated as end-of-input. Problem noted by Bryan 651338032Speter Costales. 651438032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 651538032Speter to the queue file. Fix from John Hughes of Atlantic 651638032Speter Technologies, Inc. 651738032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 651838032Speter if this happens in a queue run it can cause nasty delays. 651938032Speter Problem noted by Mark Horton of AT&T. 652038032Speter If userdb entries pointed to userdb entries, and there were multiple 652138032Speter values for a given key, the database cursor would get 652238032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 652338032Speter of Georgia Tech. Fixed by reading all the values and creating 652438032Speter a comma-separated list; thus, the -v output will be somewhat 652538032Speter different for this case. 652638032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 652738032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 652838032Speter of Stanford University. 652938032Speter When envelopes were split due to aliases with owner- aliases, and 653038032Speter there was some error on one of the lists, more than one of 653138032Speter the owners would get the message. Problem pointed out by 653238032Speter Roy Mongiovi of Georgia Tech. 653338032Speter Detect excessive recursion in macro expansions, e.g., $X defined 653438032Speter in terms of $Y which is defined in terms of $X. Problem 653538032Speter noted by Bryan Costales; patch from Eric Wassenaar. 653638032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 653738032Speter some cases get trashed causing bogus From_ lines. Fix from 653838032Speter Kyle Jones of UUNET. 653938032Speter When doing load average initialization, if the nlist call for avenrun 654038032Speter failed, the second and subsequent lookups wouldn't notice 654138032Speter that fact causing bogus load averages to be returned. Noted 654238032Speter by Casper Dik of Sun Holland. 654338032Speter Fix problem with incompatibility with some versions of inet_aton that 654438032Speter have changed the return value to unsigned, so a check for an 654538032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 654638032Speter This could cause mail to addresses such as [foo.com] to bounce 654738032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 654838032Speter Pasteur Institute. 654938032Speter DSNs were inconsistent if a failure occurred during the DATA phase 655038032Speter rather than the RCPT phase: the Action: would be correct, but 655138032Speter the detailed status information would be wrong. Problem noted 655238032Speter by Bob Snyder of General Electric Company. 655338032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 655438032Speter that this is the initial MUA->MTA submission. The flag current 655538032Speter does nothing, but in future releases (when MUAs start using 655638032Speter these flags) it will probably turn on things like DNS 655738032Speter canonification. 655838032Speter Default end-of-line string (E= specification on mailer [M] lines) 655938032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 656038032Speter mailers. 656138032Speter Change the internal definition for the *file* and *include* mailers 656238032Speter to have $u in the argument vectors so that they aren't 656338032Speter misinterpreted as SMTP mailers and thus use \r\n line 656438032Speter termination. This will affect anyone who has redefined 656538032Speter either of these in their configuration file. 656638032Speter Don't assume that IDENT servers close the connection after a query; 656738032Speter responses can be newline terminated. From Terry Kennedy of 656838032Speter St. Peter's College. 656938032Speter Avoid core dumps on erroneous configuration files that have 657038032Speter $#mailer with nothing following. From Bryan Costales. 657138032Speter Avoid null pointer dereference with high debug values in unlockqueue. 657238032Speter Fix from Randy Martin of Clemson University. 657338032Speter Fix possible buffer overrun when expanding very large macros. Fix 657438032Speter from Kyle Jones of UUNET. 657538032Speter After 25 EXPN or VRFY commands, start pausing for a second before 657638032Speter processing each one. This avoids a certain form of denial 657738032Speter of service attack. Potential attack pointed out by Bryan 657838032Speter Costales. 657938032Speter Allow new named (not numbered!) config file rules to do validity 658038032Speter checking on SMTP arguments: check_mail for MAIL commands and 658138032Speter check_rcpt for RCPT commands. These rulesets can do anything 658238032Speter they want; their result is ignored unless they resolve to the 658338032Speter $#error mailer, in which case the indicated message is printed 658438032Speter and the command is rejected. Similarly, the check_compat 658538032Speter ruleset is called before delivery with "from_addr $| to_addr" 658638032Speter (the $| is a meta-symbol used to separate the two addresses); 658738032Speter it can give a "this sender can't send to this recipient" 658838032Speter notification. Note that this patch allows $| to stand alone 658938032Speter in rulesets. 659038032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 659138032Speter that have the name, IP address, and port number (respectively) 659238032Speter of the SMTP client (that is, the entity at the other end of 659338032Speter the connection. These can be used in (e.g.) check_rcpt to 659438032Speter verify that someone isn't trying to relay mail through your 659538032Speter host inappropriately. Be sure to use the deferred evaluation 659638032Speter form, for example $&{client_name}, to avoid having these bound 659738032Speter when sendmail reads the configuration file. 659838032Speter Add new config file rule check_relay to check the incoming connection 659938032Speter information. Like check_compat, it is passed the host name 660038032Speter and host address separated by $| and can reject connections 660138032Speter on that basis. 660238032Speter Allow IDA-style recursive function calls. Code contributed by Mark 660338032Speter Lovell and Paul Vixie. 660438032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 660538032Speter a virtual UUCP address using either a domain address or the $k 660638032Speter macro. Based on code contributed by Mark Lovell and Paul 660738032Speter Vixie. 660838032Speter Add Stanford LDAP map. Requires special libraries that are not 660938032Speter included with sendmail.

Bense 661038032Speter <bbense@networking.stanford.edu>; contact him for support. 661138032Speter See also the src/READ_ME file. 661238032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 661338032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 661438032Speter only for debugging deep bits of code where it is important to 661538032Speter distinguish between the single-character metasymbol $+ and the 661638032Speter two characters $, +. 661738032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 661838032Speter debug_dumpstate. 661938032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 662038032Speter files that are group writable are considered "unsafe" -- that 662138032Speter is, programs and files referenced from such files are not 662238032Speter valid recipients. 662338032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 662438032Speter name that was not in DNS or was a domain-literal. Problem 662538032Speter noted by Tom May. 662638032Speter Change the introduction to error messages to more clearly delineate 662738032Speter permanent from temporary failures; if both existed in a 662838032Speter single message it could be confusing. Suggested by John 662938032Speter Beck of InReference, Inc. 663038032Speter The IngoreDot (i) option didn't work for lines that were terminated 663138032Speter with CRLF. Problem noted by Ted Stockwell of Secure 663238032Speter Computing Corporation. 663338032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 663438032Speter message headers. Problem reported by Matt Dillon of Best 663538032Speter Internet Communications. 663638032Speter Check for bogus characters in the 0200-0237 range; since these are 663738032Speter used internally, very strange errors can occur if those 663838032Speter characters appear in headers. Problem noted by Anders Gertz 663938032Speter of Lysator. 664038032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 664138032Speter recipient mailer has the F=9 flag set, and only works on 664238032Speter text/plain body types. Code contributed by Marius Olafsson 664338032Speter of the University of Iceland. 664438032Speter Special case "postmaster" name so that it is always treated as lower 664538032Speter case in alias files regardless of configuration settings; 664638032Speter this prevents some potential problems where "Postmaster" or 664738032Speter "POSTMASTER" might not match "postmaster". In most cases 664838032Speter this change is a no-op. 664938032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 665038032Speter Costales. 665138032Speter The -a map flag was ignored for dequote maps. Problem noted by 665238032Speter Bryan Costales. 665338032Speter Fix core dump when a lookup of a class "prog" map returns no 665438032Speter response. Patch from Bryan Costales. 665538032Speter Log instances where sendmail is deferring or rejecting connections 665638032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 665738032Speter Include port number in process title for network daemons. Suggested 665838032Speter by Kyle Jones of UUNET. 665938032Speter Send ``double bounces'' (errors that occur when sending an error 666038032Speter message) to the address indicated in the DoubleBounceAddress 666138032Speter option (default: postmaster). Previously they were always 666238032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 666338032Speter Add new mode, -bD, that acts like -bd in all respects except that 666438032Speter it runs in foreground. This is useful for using with a 666538032Speter wrapper that "watches" system services. Suggested by Kyle 666638032Speter Jones of UUNET. 666738032Speter Fix botch in spacing around (parenthesized) comments in addresses 666838032Speter when the comment comes before the address. Patch from 666938032Speter Motonori Nakamura of Kyoto University. 667038032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 667138032Speter that are being bounced to postmaster, rather than "Returned 667238032Speter mail". This permits the person who is postmaster more 667338032Speter easily determine what messages are to their role as 667438032Speter postmaster versus bounces to mail they actually sent. Based 667538032Speter on a suggestion by Motonori Nakamura. 667638032Speter Add new value "time" for QueueSortOrder option; this causes the queue 667738032Speter to be sorted strictly by the time of submission. Note that 667843730Speter this can cause very bad behavior over slow lines (because 667938032Speter large jobs will tend to delay small jobs) and on nodes with 668038032Speter heavy traffic (because old things in the queue for hosts that 668138032Speter are down delay processing of new jobs). Also, this does not 668238032Speter guarantee that jobs will be delivered in submission order 668338032Speter unless you also set DeliveryMode=queue. In general, it should 668438032Speter probably only be used on the command line, and only in 668538032Speter conjunction with -qRhost.domain. In fact, there are very few 668638032Speter cases where it should be used at all. Based on an 668738032Speter implementation by Motonori Nakamura. 668838032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 668938032Speter the same manner as other rulesets. Previously a temporary 669038032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 669138032Speter of Stanford University. 669238032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 669338032Speter 5yz (permanent failure) code. The next MX host will still be 669438032Speter tried if the connection cannot be opened in the first place 669538032Speter or if the MAIL command returns a 4yz (temporary failure) code. 669638032Speter (It's hard to know what to do here, since neither RFC 974 nor 669738032Speter RFC 1123 specify when to proceed to the next MX host.) 669838032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 669938032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 670038032Speter This causes map lookups that get a temporary failure (e.g., 670138032Speter name server failure) to _not_ defer the delivery of the 670238032Speter message. This should only be used if your configuration file 670338032Speter is prepared to do something sensible in this case. Based on 670438032Speter an idea by Gregory Shapiro of WPI. 670538032Speter Fix problem finding network interface addresses. Patch from 670638032Speter Motonori Nakamura. 670738032Speter Don't reject qf entries that are not owned by your effective uid if 670890792Sgshapiro you are not running set-user-ID; this makes management of 670980785Sgshapiro certain kinds of firewall setups difficult. Patch 671080785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 671138032Speter Add persistent host status. This keeps the information normally 671238032Speter maintained within a single queue run in disk files that are 671338032Speter shared between sendmail instances. The HostStatusDirectory 671438032Speter is the directory in which the information is maintained. If 671538032Speter not set, persistent host status is turned off. If not a full 671638032Speter pathname, it is relative to the queue directory. A common 671738032Speter value is ".hoststat". 671838032Speter There are also two new operation modes: 671938032Speter * -bh prints the status of hosts that have had recent 672038032Speter connections. 672138032Speter * -bH purges the host statuses. No attempt is made to save 672238032Speter recent status information. 672338032Speter This feature was originally written by Paul Vixie of Vixie 672438032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 672538032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 672638032Speter with my insistence that things fit cleanly into the V8 672738032Speter framework is gratefully appreciated. 672838032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 672938032Speter operate). Avoids letting two sendmails on the local machine 673064562Sgshapiro open connections to the same remote host at the same time. 673138032Speter This reduces load on the other machine, but can cause mail to 673238032Speter be delayed (for example, if one sendmail is delivering a huge 673338032Speter message, other sendmails won't be able to send even small 673438032Speter messages). Also, it requires another file descriptor (for the 673538032Speter lock file) per connection, so you may have to reduce 673638032Speter ConnectionCacheSize to avoid running out of per-process 673738032Speter file descriptors. Based on the persistent host status code 673838032Speter contributed by Paul Vixie and Mark Lovell. 673938032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 674038032Speter SafeFileEnvironment option is set. Problem noted by Bryan 674138032Speter Costales. 674238032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 674338032Speter file. Problem noted by Bryan Costales. 674438032Speter If a job was aborted using the interrupt signal (e.g., control-C from 674538032Speter the keyboard), on some occasions an empty df file would be 674638032Speter left around; these would collect in the queue directory. 674738032Speter Problem noted by Bryan Costales. 674838032Speter Change the makesendmail script to enhance the search for Makefiles 674938032Speter based on release number. For example, on SunOS 5.5.1, it will 675038032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 675138032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 675238032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 675338032Speter Webmasters. 675438032Speter When creating maps using "newaliases", always map the keys to lower 675538032Speter case when creating the map unless the -f flag is specified on 675638032Speter the map itself. Previously this was done based on the F=u 675738032Speter flag in the local mailer, which meant you could create aliases 675838032Speter that you could never access. Problem noted by Bob Wu of DEC. 675938032Speter When a job was read from the queue, the bits causing notification on 676038032Speter failure or delay were always set. This caused those 676138032Speter notifications to be sent even if NOTIFY=NEVER had been 676238032Speter specified. Problem noted by Steve Hubert of the University 676338032Speter of Washington, Seattle. 676438032Speter Add new configurable routine validate_connection (in conf.c). This 676538032Speter lets you decide if you are willing to accept traffic from 676638032Speter this host. If it returns FALSE, all SMTP commands will return 676738032Speter "550 Access denied". -DTCPWRAPPERS will include support for 676838032Speter TCP wrappers; you will need to add -lwrap to the link line. 676938032Speter (See src/READ_ME for details.) 677038032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 677138032Speter bounces. Some people seemed to think that this could be 677238032Speter confusing (even though it is true). Suggested by Motonori 677338032Speter Nakamura. 677438032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 677538032Speter user early in processing to avoid potential security problems. 677638032Speter However, this means that all .forward and :include: files must 677738032Speter be readable by that user, and all files to be written must be 677838032Speter writable by that user and all programs will be executed by that 677938032Speter user. It is also incompatible with the SafeFileEnvironment 678038032Speter option. In other words, it may not actually add much to 678138032Speter security. However, it should be useful on firewalls and other 678238032Speter places where users don't have accounts and the aliases file is 678338032Speter well constrained. 678438032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 678538032Speter only on the first attempt to delivery to an address. It could 678638032Speter be set to be lower than Timeout.connect on the principle that 678738032Speter the mail should go through quickly to responsive hosts; less 678838032Speter responsive hosts get to wait for the next queue run. 678938032Speter Fix a problem on Solaris that occasionally causes programs 679038032Speter (such as vacation) to hang with their standard input connected 679138032Speter to a UDP port. It also created some signal handling problems. 679238032Speter The problems turned out to be an interaction between vfork(2) 679338032Speter and some of the libraries, particularly NIS/NIS+. I am 679438032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 679538032Speter Change user class map to do the same matching that actual delivery 679638032Speter will do instead of just a /etc/passwd lookup. This adds 679738032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 679838032Speter The Timeout.* options are not safe -- they can be used to create a 679938032Speter denial-of-service attack. Problem noted by Christophe 680038032Speter Wolfhugel. 680143730Speter Don't send PostmasterCopy messages in the event of a "delayed" 680238032Speter notification.

Noted by David Linn of 686938032Speter Vanderbilt University. 687038032Speter Solaris changes for praliases, makemap, mailstats, and smrsh. 687138032Speter Previously you had to add -DSOLARIS in Makefile.dist; 687238032Speter this auto-detects. Based on a patch from Randall 687338032Speter Winchester of the University of Maryland. 687438032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 687538032Speter Robert La Ferla of Hot Software. 687638032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 687738032Speter (where "code" is an exit status) on domains (previously 687838032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 687938032Speter Foundation. 688038032Speter CONFIG: hooks for IPv6-style domain literals. 688138032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 688238032Speter if it is undefined the AliasFile option is never set; this 688338032Speter should be transparent for most everyone. Suggested by John 688438032Speter Myers of CMU. 688538032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 688638032Speter domain listed in $=w is masqueraded. With it, only those 688738032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 688838032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 688938032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 689038032Speter hosts under those domains as well as the domain headers 689138032Speter themselves. For example, if a configuration had 689238032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 689338032Speter foo.com would be masqueraded; with it, *.foo.com would be 689438032Speter masqueraded as well. Based on an implementation by Richard 689538032Speter (Pug) Bainter of U. Texas. 689638032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 689738032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 689838032Speter Keys are user names; values are outgoing mail addresses. Yes, 689938032Speter this does overlap with the user database, and figuring out 690038032Speter just when to use which one may be tricky. Based on code 690138032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 690238032Speter from Per Hedeland of Ericsson. 690338032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 690438032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 690538032Speter Keys are either fully qualified addresses or just the host 690638032Speter part (with the @ sign). For example, a table containing: 690738032Speter info@foo.com foo-info 690838032Speter info@bar.com bar-info 690938032Speter @baz.org jane@elsewhere.net 691038032Speter would send all mail destined for info@foo.com to foo-info 691138032Speter (which is presumably an alias), mail addressed to info@bar.com 691238032Speter to bar-info, and anything addressed to anyone at baz.org will 691338032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 691438032Speter and baz.org must all be in $=w. Based on discussions with 691538032Speter a great many people. 691638032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 691738032Speter Suggested by Richard Bainter. 691838032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 691938032Speter "fax" mailer. 692038032Speter CONFIG: allow mailertable entries to resolve to local:user; this 692138032Speter passes the original user@host in to procmail-style local 692238032Speter mailers as the "detail" information to allow them to do 692338032Speter additional clever processing. From Joe Pruett of 692438032Speter Teleport Corporation. Delivery to the original user can 692538032Speter be done by specifying "local:" (with nothing after the colon). 692638032Speter CONFIG: allow any context that takes "mailer:domain" to also take 692738032Speter "mailer:user@domain" to force mailing to the given user; 692838032Speter "local:user" can also be used to do local delivery. This 692938032Speter applies on *_RELAY and in the mailertable entries. Based 693038032Speter on a suggestion by Ribert Kiessling of Easynet. 693138032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 693238032Speter limits the possible domains; this reduces the number of DNS 693338032Speter lookups required to support this feature. For example, 693438032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 693538032Speter to domains under my.site.com. Code contributed by Anthony 693638032Speter Thyssen <anthony@cit.gu.edu.au>. 693738032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 693838032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 693938032Speter of WPI. 694038032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 694138032Speter event you have to define local mailers. Suggested by 694238032Speter Gregory Shapiro of WPI. 694338032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 694438032Speter be misinterpreted as a list:...; syntax. Based on a patch by 694538032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 694638032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 694738032Speter remotely connected. The address host!user was being 694838032Speter converted to host!user@thishost instead of host!user@uurelay. 694938032Speter Problem noted by William Gianopoulos of Raytheon Company. 695038032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 695138032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 695238032Speter "User has moved"; the former wording was confusing if the 695338032Speter new address is still on the local host. Based on a suggestion 695438032Speter by Andreas Luik. 695538032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 695638032Speter However, the class is not pre-initialized to contain root. 695738032Speter Suggested by Gregory Neil Shapiro. 695838032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 695938032Speter Wolfhugel. 696038032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 696138032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 696238032Speter well: this produces a slightly different mailbox format (no 696338032Speter Content-Length: headers), file ownerships and modes are 696438032Speter different (not owned by group mail; mode 600 instead of 660), 696538032Speter and the local mailer flags will have to be tweaked (make them 696638032Speter match bsd4.4) in order to use this mailer. Patches from Paul 696738032Speter Hammann of the Missouri Research and Education Network. 696838032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 696938032Speter was a delivery error, such as if the ownership on the file 697038032Speter was wrong or the mode changed between the initial stat and 697138032Speter the open. Problem reported by William Colburn of the New 697238032Speter Mexico Institute of Mining and Technology. 697338032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 697438032Speter Costales. 697538032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 697638032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 697738032Speter honored.

This is not exploitable from off-site. 701438032Speter Workarounds include using a unique user for the DefaultUser 701538032Speter (old u & g options) and using smrsh as the local shell. 701638032Speter SECURITY: fix some buffer overruns; in at least one case this allows 701738032Speter a local user to get root. This is not known to be exploitable 701838032Speter from off-site. The workaround is to disable chfn(1) commands. 701938032Speter 702064562Sgshapiro8.7.5/8.7.3 1996/03/04 702138032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 702238032Speter in some case cause connections to hang or messages to have 702338032Speter extra spaces in odd places. Patch from Eric Wassenaar; 702438032Speter reports from Eric Hall of Chiron Corporation, Stephen 702538032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 702638032Speter and others. 702738032Speter 702864562Sgshapiro8.7.4/8.7.3 1996/02/18 702938032Speter SECURITY: In some cases it was still possible for an attacker to 703038032Speter insert newlines into a queue file, thus allowing access to 703138032Speter any user (except root). 703238032Speter CONFIG: no changes -- it is not a bug that the configuration 703338032Speter version number is unchanged. 703438032Speter 703564562Sgshapiro8.7.3/8.7.3 1995/12/03 703638032Speter Fix botch in name server timeout in RCPT code; this problem caused 703738032Speter two responses in SMTP, which breaks things horribly. Fix 703838032Speter from Gregory Neil Shapiro of WPI. 703938032Speter Verify that L= value on M lines cannot be negative, which could cause 704038032Speter negative array subscripting. Not a security problem since 704138032Speter this has to be in the config file, but it could have caused 704238032Speter core dumps. Pointed out by Bryan Costales. 704338032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 704438032Speter Costales. 704538032Speter PORTABILITY FIXES: 704638032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 704738032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 704838032Speter order. Tweak it to work properly. Based on fixes 704938032Speter from Fletcher Mattox of UTexas and Betty Lee of 705038032Speter Stanford University. 705138032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 705238032Speter Deficiency pointed out by Bryan Costales of ICSI. 705338032Speter 705464562Sgshapiro8.7.2/8.7.2 1995/11/19 705538032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 705638032Speter OperatorChars, and UnixFromLine options. They were not 705738032Speter properly repaired in 8.7.1. 705838032Speter Completely delete the Bcc: header if and only if there are other 705938032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 706038032Speter last being a historic botch, of course). If Bcc: is the 706138032Speter only recipient header in the message, its value is tossed, 706243730Speter but the header name is kept. The old behavior (always keep 706338032Speter the header name and toss the value) allowed primary recipients 706438032Speter to see that a Bcc: went to _someone_. 706538032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 706638032Speter sender to <address> using -f'' syslog messages. Suggested 706738032Speter by Kari Hurtta. 706838032Speter If a sequence or switch map lookup entry gets a tempfail but then 706938032Speter continues on to another map type, but the name is not found, 707038032Speter return a temporary failure from the sequence or switch map. 707138032Speter For example, if hosts search ``dns files'' and DNS fails 707238032Speter with a tempfail, the hosts map will go on and search files, 707338032Speter but if it fails the whole thing should be a tempfail, not 707438032Speter a permanent (host unknown) failure, even though that is the 707538032Speter failure in the hosts.files map. This error caused hard 707638032Speter bounces when it should have requeued. 707738032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 707890792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 707938032Speter working properly due to excessive paranoia. Pointed out by 708038032Speter John Hawkinson of Panix. 708138032Speter An SMTP RCPT command referencing a host that gave a nameserver 708238032Speter timeout would return a 451 command (8.6 accepted it and 708343730Speter queued it locally). Revert to the 8.6 behavior in order 708438032Speter to simplify queue management for clustered systems. Suggested 708538032Speter by Gregory Neil Shapiro of WPI. The same problem could break 708638032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 708738032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 708838032Speter Infobiogen. 708938032Speter Fix possible buffer overflow in munchstring(). This was not a security 709038032Speter problem because you couldn't specify any argument to this 709138032Speter without first giving up root privileges, but it is still a 709238032Speter good idea to avoid future problems. Problem noted by John 709338032Speter Hawkinson and Sam Hartman of MIT. 709438032Speter ``452 Out of disk space for temp file'' messages weren't being 709538032Speter printed. Fix from David Perlin of Nanosoft. 709643730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 709738032Speter is not set, since this is required to get the actual DSNs 709838032Speter created. Problem pointed out by John Gardiner Myers of CMU. 709938032Speter Log permission problems that cause .forward and :include: files to 710038032Speter be untrusted or ignored on log level 12 and higher. Suggested 710138032Speter by Randy Martin of Clemson University. 710238032Speter Allow user ids in U= clauses of M lines to have hyphens and 710338032Speter underscores. 710438032Speter Fix overcounting of recipients -- only happened when sending to an 710538032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 710638032Speter of Systems and Computer Technology Corporation. 710738032Speter If a message is sent to an address that fails, the error message that 710838032Speter is returned could show some extraneous "success" information 710938032Speter included even if the user did not request success notification, 711038032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 711138032Speter Config files that had no AliasFile definition were defaulting to 711238032Speter using /etc/aliases; this caused problems with nullclient 711338032Speter configurations. Change it back to the 8.6 semantics of 711438032Speter having no local alias file unless it is declared. Problem 711538032Speter noted by Charles Karney of Princeton University. 711638032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 711738032Speter Costales of ICSI. 711838032Speter Map lookups of class "userdb" maps were always case sensitive; they 711938032Speter should be controlled by the -f flag like other maps.

Patch from Booker C. Bense of Stanford 714238032Speter University. 714338032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 714438032Speter the parent should do this. Fix from Brian Coan of the 714538032Speter Association for Progressive Communications. 714638032Speter If MinQueueAge was set and a message was considered but not run 714738032Speter during a queue run and the Timeout.queuereturn interval was 714838032Speter reached, a "timed out" error message would be returned that 714938032Speter didn't include the failed address (and claimed to be a warning 715038032Speter even though it was fatal). The fix is to not return such 715138032Speter messages until they are actually tried, i.e., in the next 715238032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 715338032Speter SINTEF RUNIT, Oslo. 715438032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 715538032Speter that have the hes_getmailhost() routine.

From 716738032Speter James B. Davis of TCI. 716838032Speter DomainOS: Makefile.DomainOS doesn't require -ldbm. From 716938032Speter Don Lewis of Silicon Systems. 717038032Speter HP-UX 10: rename Makefile.HP-UX.10 => Makefile.HP-UX.10.x 717138032Speter so that the makesendmail script will find it. Pointed 717238032Speter out by Richard Allen of the University of Iceland. 717338032Speter Also, use -Aa -D_HPUX_SOURCE instead of -Ae, which 717438032Speter isn't supported on all compilers. 717538032Speter UXPDS: compilation fixes from Diego R. Lopez. 717638032Speter CONFIG: FAX mailer wasn't setting .FAX as a pseudo-domain unless 717738032Speter you also had a FAX_RELAY.

Based on 718738032Speter a bug report submitted by Paul Hoffman of Proper Publishing. 718838032Speter CONFIG: Make OSTYPE files consistently not override settings that 718938032Speter have already been set. Previously it worked differently 719038032Speter for different files. 719138032Speter CONFIG: Change relay mailer to do masquerading like 8.6 did. My take 719238032Speter is that this is wrong, but the change was causing problems 719338032Speter for some people. From Per Hedeland of Ericsson. 719438032Speter CONTRIB: bitdomain.c patch from John Gardiner Myers <jgm+@CMU.EDU>; 719538032Speter portability changes for Posix environments (no functional 719638032Speter changes). 719738032Speter 719864562Sgshapiro8.7.1/8.7.1 1995/10/01 719938032Speter Old macros that have become options (SmtpGreetingMessage, 720038032Speter OperatorChars, and UnixFromLine) didn't allow backslash 720138032Speter escapes in the options, where they previously had. Bug 720238032Speter pointed out by John Hawkinson of MIT. 720338032Speter Fix strange case of an executable called by a program map that 720438032Speter returns a value but also a non-zero exit status; this 720538032Speter would give contradictory results in the higher level; in 720638032Speter particular, the default clause in the map lookup would be 720738032Speter ignored. Change to ignore the value if the program returns 720838032Speter non-zero exit status. From Tom Moore of AT&T GIS. 720938032Speter Shorten parameters passed to syslog() in some contexts to avoid a 721038032Speter bug in many vendors' implementations of that routine. Although 721138032Speter this isn't really a bug in sendmail per se, and my solution 721238032Speter has to assume that syslog() has at least a 1K buffer size 721338032Speter internally (I know some vendors have shortened this 721438032Speter dramatically -- they're on their own), sendmail is a popular 721538032Speter target. Also, limit the size of %s arguments in sprintf. 721638032Speter These both have possible security implications. Solutions 721738032Speter suggested by Casper Dik of Sun's Network Security Group 721838032Speter (Holland), Mark Seiden, and others. 721938032Speter Fix a problem that might cause a non-standard -B (body type) 722038032Speter parameter to be passed to the next server with undefined 722138032Speter results. This could have security implications. 722238032Speter If a filesystem was at > 100% utilization, the freediskspace() 722338032Speter routine incorrectly returned an error rather than zero. 722438032Speter Problem noted by G. Paul Ziemba of Alantec. 722538032Speter Change MX sort order so that local hostnames (those in $=w) always 722638032Speter sort first within a given preference. This forces the bestmx 722738032Speter map to always return the local host first, if it is included 722838032Speter in the list of highest priority MX records. From K. Robert 722938032Speter Elz. 723038032Speter Avoid some possible null pointer dereferences. Fixes from Randy 723138032Speter Martin <WOLF@CLEMSON.EDU> 723238032Speter When sendmail starts up on systems that have no fully qualified 723338032Speter domain name (FQDN) anywhere in the first matching host map 723438032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 723538032Speter sendmail would sleep to try to find a FQDN, which it really 723638032Speter really needs. This has been changed to fall through to the 723738032Speter next map type if it can't find a FQDN -- i.e., if the hosts 723838032Speter file doesn't have a FQDN, it will try dns even though the 723938032Speter short name was found in /etc/hosts. This is probably a crock, 724038032Speter but many people have hosts files without FQDNs. Remember: 724138032Speter domain names are your friends. 724238032Speter Log a high-priority message if you can't find your FQDN during startup. 724338032Speter Suggested by Simon Barnes of Schlumberger Limited. 724438032Speter When using Hesiod, initialize it early to improve error reporting. 724538032Speter Patch from Don Lewis of Silicon Systems, Inc. 724638032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 724738032Speter connection timeout in the kernel. Add a new "connect" timeout 724838032Speter to limit this time. Defaults to zero (use whatever the 724938032Speter kernel provides). Based on code contributed by J.R. Oldroyd 725038032Speter of TerraNet. 725138032Speter Under some circumstances, a failed message would not be properly 725238032Speter removed from the queue, causing tons of bogus error messages. 725338032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 725438032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 725538032Speter of WPI. 725638032Speter PORTABILITY FIXES: 725738032Speter On IRIX 5.x, there was an inconsistency in the setting 725838032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 727438032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 727538032Speter otherwise the F=S causes the From_ line to imply that root is 727638032Speter the sender. Problem pointed out by Claude Scarpelli of 727738032Speter Infobiogen (France). 727838032Speter NEW FILES: 727938032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 728038032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 728138032Speter src/Makefiles/Makefile.UXPDS 728238032Speter 728364562Sgshapiro8.7/8.7 1995/09/16 728438032Speter Fix a problem that could cause sendmail to run out of file 728538032Speter descriptors due to a trashed data structure after a 728638032Speter vfork. Fix from Brian Coan of the Institute for 728738032Speter Global Communications. 728838032Speter Change the VRFY response if you have disabled VRFY -- some 728938032Speter people seemed to think that it was too rude. 729038032Speter Avoid reference to uninitialized file descriptor if HASFLOCK 729138032Speter was not defined. This was used "safely" in the sense 729238032Speter that it only did a stat, but it would have set the 729338032Speter map modification time improperly. Problem pointed out 729438032Speter by Roy Mongiovi of Georgia Tech. 729538032Speter Clean up the Subject: line on warning messages and return 729638032Speter receipts so that they don't say "Returned mail:"; this 729738032Speter can be confusing. 729838032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 729938032Speter useful enough to make it worthwhile printing on "-d". 730038032Speter Avoid logging alias statistics every time you read the alias 730138032Speter file on systems with no database method compiled in. 730238032Speter If you have a name with a trailing dot, and you try looking it 730338032Speter up using gethostbyname without the dot (for /etc/hosts 730438032Speter compatibility), be sure to turn off RES_DEFNAMES and 730538032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 730638032Speter Problem noted by Charles Amos of the University of 730738032Speter Maryland. 730838032Speter Don't do timeouts in collect if you are not running SMTP. 730938032Speter There is nothing that says you can't have a long 731038032Speter running program piped into sendmail (possibly via 731138032Speter /bin/mail, which just execs sendmail). Problem reported 731238032Speter by Don "Truck" Lewis of Silicon Systems. 731338032Speter Try gethostbyname() even if the DNS lookup fails iff option I 731438032Speter is not set. This allows you to have hosts listed in 731538032Speter NIS or /etc/hosts that are not known to DNS. It's normally 731638032Speter a bad idea, but can be useful on firewall machines. This 731738032Speter should really be broken out on a separate flag, I suppose. 731838032Speter Avoid compile warnings against BIND 4.9.3, which uses function 731938032Speter prototypes.

From Kyle Jones of UUNET. 732438032Speter SECURITY: avoid denial-of-service attacks possible by destroying 732538032Speter the alias database file by setting resource limits low. 732638032Speter This involves adding two new compile-time options: 732738032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 732838032Speter available) and HASULIMIT (indicating that ulimit(2) support 732938032Speter is available -- the Release 3 form is used). The former 733038032Speter is assumed on BSD-based systems, the latter on System 733138032Speter V-based systems. Attack noted by Phil Brandenberger of 733238032Speter Swarthmore University. 733338032Speter New syntaxes in test (-bt) mode: 733438032Speter ``.Dmvalue'' will define macro "m" to "value". 733538032Speter ``.Ccvalue'' will add "value" to class "c". 733638032Speter ``=Sruleset'' will dump the contents of the indicated 733738032Speter ruleset. 733838032Speter ``=M'' will display the known mailers. 733938032Speter ``-ddebug-spec'' is equivalent to the command-line 734038032Speter -d debug flag. 734138032Speter ``$m'' will print the value of macro $m. 734238032Speter ``$=c'' will print the contents of class $=c. 734338032Speter ``/mx host'' returns the MX records for ``host''. 734438032Speter ``/parse address'' will parse address, returning the value of 734538032Speter crackaddr (essentially, the comment information) 734638032Speter and the parsed address. 734738032Speter ``/try mailer address'' will rewrite address into the form 734838032Speter it will have when presented to the indicated mailer. 734938032Speter ``/tryflags flags'' will set flags used by parsing. The 735038032Speter flags can be `H' for header or `E' for envelope, 735138032Speter and `S' for sender or `R' for recipient. These 735238032Speter can be combined, so `HR' sets flags for header 735338032Speter recipients. 735438032Speter ``/canon hostname'' will try to canonify hostname and 735538032Speter return the result. 735638032Speter ``/map mapname key'' will look up `key' in the indicated 735738032Speter `mapname' and return the result. 735838032Speter Somewhat better handling of UNIX-domain socket addresses -- it 735938032Speter should show the pathname rather than hex bytes. 736038032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 736138032Speter the header for envelope sender information and uses 736238032Speter CR-LF as message terminators. It was thought to be 736338032Speter obsolete (used only for Arpanet NCP protocols), but it 736438032Speter turns out that the UK ``Grey Book'' protocols require 736538032Speter that functionality. 736638032Speter Fix a fix in previous release -- if gethostname and gethostbyname 736738032Speter return a name without dots, and if an attempt to canonify 736838032Speter that name fails, wait one minute and try again. This can 736938032Speter result in an extra 60 second delay on startup if your system 737038032Speter hostname (as returned by hostname(1)) has no dot and no names 737138032Speter listed in /etc/hosts or your NIS map have a dot. 737238032Speter Check for proper domain name on HELO and EHLO commands per 737338032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 737438032Speter of Michigan Technological University. 737538032Speter Relax chownsafe rules slightly -- old version said that if you 737638032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 737738032Speter if fpathconf returned EINVAL or ENOSYS), assume that 737838032Speter chown is not safe. The new version falls back to whether 737938032Speter you are on a BSD system or not. This is important for 738038032Speter SunOS, which apparently always returns one of those 738138032Speter error codes. This impacts whether you can mail to files 738238032Speter or not. 738338032Speter Syntax errors such as unbalanced parentheses in the configuration 738438032Speter file could be omitted if you had "Oem" prior to the 738538032Speter syntax error in the config file. Change to always print 738638032Speter the error message. It was especially weird because it 738738032Speter would cause a "warning" message to be sent to the Postmaster 738838032Speter for every message sent (but with no transcript). Problem 738938032Speter noted by Gregory Paris of Motorola. 739038032Speter Rewrite collect and putbody to handle full 8-bit data, including 739138032Speter zero bytes. These changes are internally extensive, but 739238032Speter should have minimal impact on external function. 739338032Speter Allow full words for option names -- if the option letter is 739438032Speter (apparently) a space, then take the word following -- e.g., 739538032Speter O MatchGECOS=TRUE 739638032Speter The full list of old and new names is as follows: 739738032Speter 7 SevenBitInput 739838032Speter 8 EightBitMode 739938032Speter A AliasFile 740038032Speter a AliasWait 740138032Speter B BlankSub 740238032Speter b MinFreeBlocks/MaxMessageSize 740338032Speter C CheckpointInterval 740438032Speter c HoldExpensive 740538032Speter D AutoRebuildAliases 740638032Speter d DeliveryMode 740738032Speter E ErrorHeader 740838032Speter e ErrorMode 740938032Speter f SaveFromLine 741038032Speter F TempFileMode 741138032Speter G MatchGECOS 741238032Speter H HelpFile 741338032Speter h MaxHopCount 741438032Speter i IgnoreDots 741538032Speter I ResolverOptions 741638032Speter J ForwardPath 741738032Speter j SendMimeErrors 741838032Speter k ConnectionCacheSize 741938032Speter K ConnectionCacheTimeout 742038032Speter L LogLevel 742138032Speter l UseErrorsTo 742238032Speter m MeToo 742338032Speter n CheckAliases 742438032Speter O DaemonPortOptions 742538032Speter o OldStyleHeaders 742638032Speter P PostmasterCopy 742738032Speter p PrivacyOptions 742838032Speter Q QueueDirectory 742938032Speter q QueueFactor 743038032Speter R DontPruneRoutes 743138032Speter r, T Timeout 743238032Speter S StatusFile 743338032Speter s SuperSafe 743438032Speter t TimeZoneSpec 743538032Speter u DefaultUser 743638032Speter U UserDatabaseSpec 743743730Speter V FallbackMXHost 743838032Speter v Verbose 743938032Speter w TryNullMXList 744038032Speter x QueueLA 744138032Speter X RefuseLA 744238032Speter Y ForkEachJob 744338032Speter y RecipientFactor 744438032Speter z ClassFactor 744538032Speter Z RetryFactor 744638032Speter The old macros that passed information into sendmail have 744738032Speter been changed to options; those correspondences are: 744838032Speter $e SmtpGreetingMessage 744938032Speter $l UnixFromLine 745038032Speter $o OperatorChars 745138032Speter $q (deleted -- not necessary) 745238032Speter To avoid possible problems with an older sendmail, 745338032Speter configuration level 6 is accepted by this version of 745438032Speter sendmail; any config file using the new names should 745538032Speter specify "V6" in the configuration. 745638032Speter Change address parsing to properly note that a phrase before a 745738032Speter colon and a trailing semicolon are essentially the same 745838032Speter as text outside of angle brackets (i.e., sendmail should 745938032Speter treat them as comments). This is to handle the 746038032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 746138032Speter assume that ``group name:'' is a comment on the first 746238032Speter address and the ``;'' is a comment on the last address). 746338032Speter This requires config file support to get right. It does 746438032Speter understand that :: is NOT this syntax, and can be turned 746538032Speter off completely by setting the ColonOkInAddresses option. 746638032Speter Level 6 config files added with new mailer flags: 746738032Speter A Addresses are aliasable. 746838032Speter i Do udb rewriting on envelope as well as header 746938032Speter sender lines. Applies to the from address mailer 747038032Speter flags rather than the recipient mailer flags. 747138032Speter j Do udb rewriting on header recipient addresses. 747238032Speter Applies to the sender mailer flags rather than the 747338032Speter recipient mailer flags. 747438032Speter k Disable check for loops when doing HELO command. 747538032Speter o Always run as the mail recipient, even on local 747638032Speter delivery. 747738032Speter w Check for an /etc/passwd entry for this user. 747838032Speter 5 Pass addresses through ruleset 5. 747938032Speter : Check for :include: on this address. 748038032Speter | Check for |program on this address. 748138032Speter / Check for /file on this address. 748238032Speter @ Look up sender header addresses in the user 748338032Speter database. Applies to the mailer flags for the 748438032Speter mailer corresponding to the envelope sender 748538032Speter address, rather than to recipient mailer flags. 748638032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 748738032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 748838032Speter mailers, and the ColonOkInAddresses option. 748938032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 749038032Speter John Beck of Hewlett-Packard, who generously contributed 749138032Speter their implementation to me, which I then didn't use (see 749238032Speter mime.c for an explanation of why). This adds the 749338032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 749438032Speter to control handling of 8-bit data. These have to cope with 749538032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 749638032Speter 8-bit data that is entered without declaring it as 8-bit 749738032Speter MIME -- technically this is illegal according to the 749838032Speter specs) and labelled 8-bit data (that is, it was declared 749938032Speter as 8BITMIME in the ESMTP session or by using the 750038032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 750138032Speter set then 8-bit data is sent to non-8BITMIME machines 750238032Speter instead of converting to 7 bit (essentially using 750338032Speter just-send-8 semantics). The values for EightBitMode are: 750438032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 750538032Speter any necessary conversion of 8BITMIME to 7BIT 750638032Speter (essentially, the full MIME option). 750738032Speter p pass unlabelled 8-bit input, but convert labelled 750838032Speter 8BITMIME input to 7BIT as required (default). 750938032Speter s strict adherence: reject unlabelled 8-bit input, 751038032Speter convert 8BITMIME to 7BIT as required. The F=8 751138032Speter flag is ignored. 751238032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 751338032Speter the setting of F=8. 751438032Speter Add new internal class 'n', which is the set of MIME Content-Types 751538032Speter which can not be 8 to 7 bit encoded because of other 751638032Speter considerations. Types "multipart/*" and "message/*" are 751738032Speter never directly encoded (although their components can be). 751838032Speter Add new internal class 's', which is the set of subtypes of the 751938032Speter MIME message/* content type that can be treated as though 752038032Speter they are an RFC822 message. It is predefined to have 752138032Speter "rfc822". Suggested By Kari Hurtta. 752238032Speter Add new internal class 'e'. This is the set of MIME 752338032Speter Content-Transfer-Encodings that can be converted to 752438032Speter a seven bit format (Quoted-Printable or Base64). It is 752538032Speter preinitialized to contain "7bit", "8bit", and "binary". 752638032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 752738032Speter short name) to set the default character set to use in the 752838032Speter Content-Type: header when doing encoding of an 8-bit message 752938032Speter which isn't marked as MIME into MIME format. If the C= 753038032Speter parameter is set on the Envelope From address, use that as 753138032Speter the default encoding; else use the DefaultCharSet option. 753238032Speter If neither is set, it defaults to "unknown-8bit" as 753338032Speter suggested by RFC 1428 section 3. 753438032Speter Allow ``U=user:group'' field in mailer definition to set a default 753538032Speter user and group that a mailer will be executed as. This 753638032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 753738032Speter also set, it is the uid/gid that will always be used (that 753838032Speter is, the controlling address is ignored). The values may be 753938032Speter numeric or symbolic; if only a symbolic user is given (no 754038032Speter group) that user's default group in the passwd file is used 754138032Speter as the group. Based on code donated by Chip Rosenthal of 754238032Speter Unicom. 754338032Speter Allow `u' option to also accept user:group as a value, in the same 754438032Speter fashion as the U= mailer option. 754538032Speter Add the symbolic time zone name in the Arpanet format dates (as 754638032Speter a comment). This adds a new compile-time configuration 754738032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 754838032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 754938032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 755038032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 755138032Speter timezone()), or TZ_NONE (don't include the comment). Code 755238032Speter from Chip Rosenthal. 755338032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 755438032Speter For example, 755538032Speter O Timeout.helo = 2m 755638032Speter There are also two new suboptions "queuereturn" and 755738032Speter "queuewarn"; these subsume the old T option. Thus, to 755838032Speter set them both the preferred new syntax is 755938032Speter O Timeout.queuereturn = 5d 756038032Speter O Timeout.queuewarn = 4h 756138032Speter Sort queue by host name instead of by message priority if the 756238032Speter QueueSortOrder option (no short name) is set is set to 756338032Speter ``host''. This makes better use of the connection cache, 756438032Speter but may delay more ``interactive'' messages behind large 756538032Speter backlogs under some circumstances. This is probably a 756638032Speter good option if you have high speed links or don't do lots 756738032Speter of ``batch'' messages, but less good if you are using 756838032Speter something like PPP on a 14.4 modem. Based on code 756938032Speter contributed by Roy Mongiovi of Georgia Tech (my main 757038032Speter contribution was to make it configurable). 757138032Speter Save i-number of df file in qf file to simplify rebuilding of queue 757238032Speter after disastrous disk crash. Suggested by Kyle Jones of 757338032Speter UUNET; closely based on code from KJS DECWRL code written 757438032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 757538032Speter are NOT back compatible with 8.6 -- that is, you can convert 757638032Speter from 8.6 to 8.7, but not the other direction. 757738032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 757838032Speter route-addrs in envelopes; this is because in some cases 757938032Speter they can be sent to the shell, which interprets them as 758038032Speter I/O redirection. 758138032Speter Don't include error file (option E) with return-receipts; this 758238032Speter can be confusing. 758338032Speter Don't send "Warning: cannot send" messages to owner-* or 758438032Speter *-request addresses. Suggested by Christophe Wolfhugel 758538032Speter of the Institut Pasteur, Paris. 758638032Speter Allow -O command line flag to set long form options. 758738032Speter Add "MinQueueAge" option to set the minimum time between attempts 758838032Speter to run the queue. For example, if the queue interval 758938032Speter (-q value) is five minutes, but the minimum queue age 759038032Speter is fifteen minutes, jobs won't be tried more often than 759138032Speter once every fifteen minutes. This can be used to give 759238032Speter you more responsiveness if your delivery mode is set to 759338032Speter queue-only. 759438032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 759538032Speter :include: and .forward files. 759638032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 759738032Speter key field name, the value field name, and the field 759838032Speter delimiter. The field delimiter can be a single character 759938032Speter or the sequence "\t" or "\n" for tab or newline. 760038032Speter These are for use by NIS+ and similar access methods. 760138032Speter Change maps to always strip quotes before lookups; the -q flag 760243730Speter turns off this behavior. Suggested by Motonori Nakamura. 760338032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 760438032Speter key and value field names respectively. Code donated by 760538032Speter Sun Microsystems. 760638032Speter Add "hesiod" map class. The "file name" is used as the 760738032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 760838032Speter first value found for the match. Code donated by Scott 760938032Speter Hutton of Indiana University. 761038032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 761138032Speter specify the name of the property that is searched as the 761238032Speter key and a -v flag to specify the name of the property that 761338032Speter is returned as the value (defaults to "members"). The 761438032Speter default map is "/aliases". Some code based on code 761538032Speter contributed by Robert La Ferla of Hot Software. 761638032Speter Add "text" map class. This does slow, linear searches through 761738032Speter text files. The -z flag specifies a column delimiter 761838032Speter (defaults to any sequence of white space), the -k flag 761938032Speter sets the key column number, and the -v flag sets the 762038032Speter value column number. Lines beginning with `#' are treated 762138032Speter as comments. 762238032Speter Add "program" map class to execute arbitrary programs. The search 762338032Speter key is presented as the last argument; the output is one 762438032Speter line read from the programs standard output. Exit statuses 762538032Speter are from sysexits.h. 762638032Speter Add "sequence" map class -- searches maps in sequence until it 762738032Speter finds a match. For example, the declarations: 762838032Speter Kmap1 ... 762938032Speter Kmap2 ... 763038032Speter Kmapseq sequence map1 map2 763138032Speter defines a map "mapseq" that first searches map1; if the 763238032Speter value is found it is returned immediately, otherwise 763338032Speter map2 is searched and the value returned. 763438032Speter Add "switch" map class. This is much like "sequence" except that 763538032Speter the ordering is fetched from an external file, usually 763638032Speter the system service switch. The parameter is the name of 763738032Speter the service to switch on, and the maps that it will use 763838032Speter are the name of the switch map followed by ".service_type". 763938032Speter For example, if the declaration of the map is 764038032Speter Ksample switch hosts 764138032Speter and the system service switch specifies that hosts are 764238032Speter looked up using dns and nis in that order, then this is 764338032Speter equivalent to 764438032Speter Ksample sequence sample.dns sample.nis 764538032Speter The subordinate maps (sample.*) must already be defined. 764638032Speter Add "user" map class -- looks up users using getpwnam. Takes a 764738032Speter "-v field" flag on the definition that tells what passwd 764838032Speter entry to return -- legal values are name, passwd, uid, gid, 764938032Speter gecos, dir, and shell. Generally expected to be used with 765038032Speter the -m (matchonly) flag. 765138032Speter Add "bestmx" map class -- returns the best MX value for the host 765238032Speter listed as the value. If there are several "best" MX records 765338032Speter for this host, one will be chosen at random. 765438032Speter Add "userdb" map class -- looks up entries in the user database. 765538032Speter The "file name" is actually the tag that will be used, 765638032Speter typically "mailname". If there are multiple entries 765738032Speter matching the name, the one chosen is undefined. 765838032Speter Add multiple queue timeouts (both return and warning). These are 765938032Speter set by the Precedence: or Priority: header fields to one of 766038032Speter three values. If a Priority: is set and has value "normal", 766164562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 766238032Speter used. If no priority is set, the Precedence: is consulted; 766338032Speter if negative, non-urgent timeouts are used; if greater than 766438032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 766538032Speter are used. The timeouts are set by setting the six timeouts 766638032Speter queue{warn,return}.{urgent,normal,non-urgent}. 766738032Speter Fix problem when a mail address is resolved to a $#error mailer 766838032Speter with a temporary failure indication; it works in SMTP, 766938032Speter but when delivering locally the mail is silently discarded. 767038032Speter This patch, from Kyle Jones of UUNET, bounces it instead 767138032Speter of queueing it (queueing is very hard). 767238032Speter When using /etc/hosts or NIS-style lookups, don't assume that 767338032Speter the first name in the list is the best one -- instead, 767438032Speter search for the first one with a dot. For example, if 767538032Speter an /etc/hosts entry reads 767638032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 767738032Speter this change will use the second name as the canonical 767838032Speter machine name instead of the initial, unqualified name. 767938032Speter Change dequote map to replace spaces in quoted text with a value 768038032Speter indicated by the -s flag on the dequote map definition. 768138032Speter For example, ``Mdequote dequote -s_'' will change 768238032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 768338032Speter quoted (because of the space character). Suggested by Dan 768438032Speter Oscarsson for use in X.400 addresses. 768538032Speter Implement long macro names as ${name}; long class names can 768638032Speter be similarly referenced as $={name} and $~{name}. 768738032Speter Definitions are (e.g.) ``D{name}value''. Names that have 768838032Speter a leading lower case letter or punctuation characters are 768938032Speter reserved for internal use by sendmail; i.e., config files 769038032Speter should use names that begin with a capital letter. Based 769138032Speter on code contributed by Dan Oscarsson. 769238032Speter Fix core dump if getgrgid returns a null group list (as opposed 769338032Speter to an empty group list, that is, a pointer to a list 769438032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 769538032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 769638032Speter failed, it called syserr which called newstr which called 769738032Speter xalloc.... The newstr is now avoided for "panic" messages. 769838032Speter Reported by Stuart Kemp of James Cook University. 769938032Speter Improve connection cache timeouts; previously, they were not even 770038032Speter checked if you were delivering to anything other than an 770138032Speter IPC-connected host, so a series of (say) local mail 770238032Speter deliveries could cause cached connections to be open 770338032Speter much longer than the specified timeout. 770438032Speter If an incoming message exceeds the maximum message size, stop 770538032Speter writing the incoming bytes to the queue data file, since 770638032Speter this can fill your mqueue partition -- this is a possible 770738032Speter denial-of-service attack. 770838032Speter Don't reject all numeric local user names unless HESIOD is 770938032Speter defined. It turns out that Posix allows all-numeric 771038032Speter user names. Fix from Tony Sanders of BSDI. 771138032Speter Add service switch support. If the local OS has a service 771238032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 771338032Speter on DEC systems) that will be used; otherwise, it falls back 771438032Speter to using a local mechanism based on the ServiceSwitchFile 771538032Speter option (default: /etc/service.switch). For example, if the 771638032Speter service switch lists "files" and "nis" for the aliases 771738032Speter service, that will be the default lookup order. the "files" 771838032Speter ("local" on DEC) service type expands to any alias files 771938032Speter you listed in the configuration file, even if they aren't 772038032Speter actually file lookups. 772138032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 772238032Speter variable which tells whether or not DNS should be considered 772338032Speter canonical. This is now determined based on whether or not 772438032Speter "dns" is in the service list for "hosts". 772538032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 772638032Speter Status Notifications). DSN notifications override 772738032Speter Return-Receipt-To: headers, which are bogus anyhow -- 772838032Speter support for them has been removed. 772938032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 773038032Speter definitions to define the types used in DSN returns for 773138032Speter MTA names, addresses, and diagnostics respectively. 773238032Speter Extend heuristic to force running in ESMTP mode to look for the 773338032Speter five-character string "ESMTP" anywhere in the 220 greeting 773438032Speter message (not just the second line). This is to provide 773538032Speter better compatibility with other ESMTP servers. 773638032Speter Print sequence number of job when running the queue so you can 773738032Speter easily see how much progress you have made. Suggested 773838032Speter by Peter Wemm of DIALix. 773938032Speter Map newlines to spaces in logged message-ids; some versions of 774038032Speter syslog truncate the rest of the line after newlines. 774138032Speter Suggested by Fletcher Mattox of U. Texas. 774238032Speter Move up forking for job runs so that if a message is split into 774338032Speter multiple envelopes you don't get "fork storms" -- this 774438032Speter also improves the connection cache utilization. 774538032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 774638032Speter the purposes of refusing to send error returns. Suggested 774738032Speter by Motonori Nakamura of Ritsumeikan University. 774838032Speter Relax rules on when a file can be written when referenced from 774938032Speter the aliases file: use the default uid/gid instead of the 775038032Speter real uid/gid. This allows you to create a file owned by 775138032Speter and writable only by the default uid/gid that will work 775290792Sgshapiro all the time (without having the set-user-ID bit set). Change 775338032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 775438032Speter Microsystems. 775538032Speter Add "DialDelay" option (no short name) to provide an "extra" 775638032Speter delay for dial on demand systems. If this is non-zero 775738032Speter and a connect fails, sendmail will wait this long and 775838032Speter then try again. If it takes longer than the kernel 775938032Speter timeout interval to establish the connection, this 776038032Speter option can give the network software time to establish 776138032Speter the link. The default units are seconds. 776238032Speter Move logging of sender information to be as early as possible; 776338032Speter previously, it could be delayed a while for SMTP mail 776438032Speter sent to aliases. Suggested by Brad Knowles of the 776538032Speter Defense Information Systems Agency. 776638032Speter Call res_init() before setting RES_DEBUG; this is required by 776738032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 776838032Speter the National Computer Security Center. 776938032Speter Add xdelay= field in logs -- this is a transaction delay, telling 777038032Speter you how long it took to deliver to this address on the 777138032Speter last try. It is intended to be used for sorting mailing 777238032Speter lists to favor "quick" addresses. Provided for use by 777338032Speter the mailprio scripts (see below). 777438032Speter If a map cannot be opened, and that map is non-optional, and 777538032Speter an address requires that map for resolution, queue the 777638032Speter map instead of bouncing it. This involves creating a 777738032Speter pseudo-class of maps called "bogus-map" -- if a required 777838032Speter map cannot be opened, the class is changed to bogus-map; 777938032Speter all queries against bogus-map return "tempfail". The 778038032Speter bogus-map class is not directly accessible. A sample 778138032Speter implementation was donated by Jem Taylor of Glasgow 778238032Speter University Computing Service. 778338032Speter Fix a possible core dump when mailing to a program that talks 778438032Speter SMTP on its standard input. Fix from Keith Moore of 778538032Speter the University of Kentucky. 778638032Speter Make it possible to resolve filenames to $#local $: @ /filename; 778738032Speter previously, the "@" would cause it to not be recognized 778838032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 778938032Speter Accept a -1 signal to re-exec the daemon. This only works if 779038032Speter argv[0] is a full path to sendmail. 779138032Speter Fix bug in "addr=..." field in O option on little-endian machines 779238032Speter -- the network number wasn't being converted to network 779338032Speter byte order. Patch from Kurt Lidl of Pix Technologies 779438032Speter Corporation. 779538032Speter Pre-initialize the resolver early on; this is to avoid a bug with 779638032Speter BIND 4.9.3 that can cause the _res.retry field to get 779738032Speter reset to zero, causing all name server lookups to time 779838032Speter out. Fix from Matt Day of Artisoft. 779938032Speter Restore T line (trusted users) in config file -- but instead of 780038032Speter locking out the -f flag, they just tell whether or not 780138032Speter an X-Authentication-Warning: will be added. This really 780238032Speter just creates new entries in class 't', so "Ft/file/name" 780338032Speter can be used to read trusted user names from a file. 780438032Speter Trusted users are also allowed to execute programs even 780538032Speter if they have a shell that isn't in /etc/shells. 780638032Speter Improve NEWDB alias file rebuilding so it will create them 780738032Speter properly if they do not already exist. This had been 780838032Speter a MAYBENEXTRELEASE feature in 8.6.9. 780938032Speter Check for @:@ entry in NIS maps before starting up to avoid 781038032Speter (but not prevent, sigh) race conditions. This ought to 781138032Speter be handled properly in ypserv, but isn't. Suggested by 781238032Speter Michael Beirne of Motorola. 781338032Speter Refuse connections if there isn't enough space on the filesystem 781438032Speter holding the queue. Contributed by Robert Dana of Wolf 781538032Speter Communications. 781638032Speter Skip checking for directory permissions in the path to a file 781738032Speter when checking for file permissions iff setreuid() 781838032Speter succeeded -- it is unnecessary in that case. This avoids 781938032Speter significant performance problems when looking for .forward 782038032Speter files. Based on a suggestion by Win Bent of USC. 782138032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 782238032Speter arbitrary ruleset number assigned or "Sname = integer" 782338032Speter to assign a specific ruleset number. Reference is 782438032Speter $>name_or_number. Names can be composed of alphas, digits, 782538032Speter underscore, or hyphen (first character must be non-numeric). 782638032Speter Allow -o flag on AliasFile lines to make the alias file optional. 782738032Speter From Bryan Costales of ICSI. 782838032Speter Add NoRecipientAction option to handle the case where there is 782938032Speter no legal recipient header in the message. It can take 783038032Speter on values: 783138032Speter None Leave the message as is. The 783238032Speter message will be passed on even 783338032Speter though it is in technically 783438032Speter illegal syntax. 783538032Speter Add-To Add a To: header with any 783638032Speter recipients that it can find from 783738032Speter the envelope. This risks exposing 783838032Speter Bcc: recipients. 783938032Speter Add-Apparently-To Add an Apparently-To: header. This 784038032Speter has almost no redeeming social value, 784138032Speter and is provided only for back 784238032Speter compatibility. 784338032Speter Add-To-Undisclosed Add a header reading 784438032Speter To: undisclosed-recipients:; 784538032Speter which will have the effect of 784638032Speter making the message legal without 784738032Speter exposing Bcc: recipients. 784838032Speter Add-Bcc To add an empty Bcc: header. 784938032Speter There is a chance that mailers down 785038032Speter the line will delete this header, 785138032Speter which could cause exposure of Bcc: 785238032Speter recipients. 785338032Speter The default is NoRecipientAction=None. 785438032Speter Truncate (rather than delete) Bcc: lines in the header. This 785538032Speter should prevent later sendmails (at least, those that don't 785638032Speter themselves delete Bcc:) from considering this message to 785738032Speter be non-conforming -- although it does imply that non-blind 785838032Speter recipients can see that a Bcc: was sent, albeit not to whom. 785938032Speter Add SafeFileEnvironment option. If declared, files named as delivery 786038032Speter targets must be regular files in addition to the regular 786138032Speter checks. Also, if the option is non-null then it is used as 786238032Speter the name of a directory that is used as a chroot(2) 786338032Speter environment for the delivery; the file names listed in an 786438032Speter alias or forward should include the name of this root. 786538032Speter For example, if you run with 786638032Speter O SafeFileEnvironment=/arch 786738032Speter then aliases should reference "/arch/rest/of/path". If a 786838032Speter value is given, sendmail also won't try to save to 786938032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 787038032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 787138032Speter Support -A flag for alias files; this will comma concatenate like 787238032Speter entries. For example, given the aliases: 787338032Speter list: member1 787438032Speter list: member2 787538032Speter and an alias file declared as: 787638032Speter OAhash:-A /etc/aliases 787738032Speter the final alias inserted will be "list: member1,member2"; 787838032Speter without -A you will get an error on the second and subsequent 787938032Speter alias for "list".

Suggested by Liudvikas Bukys. 788138032Speter Fix a problem that could cause very long addresses to core dump in 788238032Speter some special circumstances. Problem pointed out by Allan 788338032Speter Johannesen. 788438032Speter (Internal change.) Change interface to expand() (macro expansion) 788538032Speter to be simpler and more consistent. 788638032Speter Delete check for funny qf file names. This didn't really give 788738032Speter any extra security and caused some people some problems. 788838032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 788938032Speter at compile time.) Suggested by Kyle Jones of UUNET. 789038032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 789138032Speter merge with DSN code; this is simpler and more consistent. 789238032Speter This may affect some people who have written their own 789338032Speter checkcompat() routine. 789438032Speter (Internal change.) Eliminate `D' line in qf file. The df file 789538032Speter is now assumed to be the same name as the qf file (with 789638032Speter the `q' changed to a `d', of course). 789738032Speter Avoid forking for delivery if all recipient mailers are marked as 789838032Speter "expensive" -- this can be a major cost on some systems. 789938032Speter Essentially, this forces sendmail into "queue only" mode 790038032Speter if all it is going to do is queue anyway. 790138032Speter Avoid sending a null message in some rather unusual circumstances 790238032Speter (specifically, the RCPT command returns a temporary 790338032Speter failure but the connection is lost before the DATA 790438032Speter command). Fix from Scott Hammond of Secure Computing 790538032Speter Corporation. 790638032Speter Change makesendmail to use a somewhat more rational naming scheme: 790738032Speter Makefiles and obj directories are named $os.$rel.$arch, 790838032Speter where $os is the operating system (e.g., SunOS), $rel is 790938032Speter the release number (e.g., 5.3), and $arch is the machine 791038032Speter architecture (e.g., sun4). Any of these can be omitted, 791138032Speter and anything after the first dot in a release number can 791238032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 791338032Speter version used $os.$arch.$rel and was rather less general. 791438032Speter Change makesendmail to do a "make depend" in the target directory 791538032Speter when it is being created. This involves adding an empty 791638032Speter "depend:" entry in most Makefiles. 791738032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 791838032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 791938032Speter of the Finnish Meteorological Institute. 792038032Speter Fix problem that could cause multiple responses to DATA command 792138032Speter on header syntax errors (e.g., lines beginning with colons). 792238032Speter Problem noted by Jens Thomassen of the University of Oslo. 792338032Speter Don't let null bytes in headers cause truncation of the rest of 792438032Speter the header. 792538032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 792638032Speter Increase timeouts on message data puts to allow time for receivers 792738032Speter to canonify addresses in headers on the fly. This is still 792838032Speter a rather ugly heuristic. From Motonori Nakamura. 792938032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 793038032Speter records are not used when canonifying names, and when MX 793138032Speter lookups are done for addressing they must be fully 793238032Speter qualified. This is useful if you have a wildcard MX record, 793338032Speter although it may cause other problems. In general, don't use 793438032Speter wildcard MX records. Patch from Motonori Nakamura. 793538032Speter Eliminate default two-line SMTP greeting message. Instead of 793638032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 793738032Speter is added between the first and second word of the first 793838032Speter line of the greeting message (i.e., immediately after the 793938032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 794038032Speter compile flag. Old sendmails won't see the ESMTP, but that's 794138032Speter acceptable because SIZE was the only useful extension that 794238032Speter old sendmails understand. 794338032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 794438032Speter invoked state dumps. From Masaharu Onishi. 794538032Speter Allow on-line comments in .forward and :include: files; they are 794638032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 794738032Speter is a space or a tab. This is intended for native 794838032Speter representation of non-ASCII sets such as Japanese, where 794938032Speter existing encodings would be unreadable or would lose 795038032Speter data -- for example, 795138032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 795238032Speter (romanized/less information) 795338032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 795438032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 795538032Speter (with MIME encoding, not human readable) 795638032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 795738032Speter (native encoding with ISO-2022-JP) 795838032Speter The last form is human readable in the Japanese environment. 795938032Speter Based on a fix from (surprise!) Motonori Nakamura. 796038032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 796138032Speter messages to that host; these are most frequently associated 796238032Speter with addresses rather than the host, with the exception of 796338032Speter 421 (service shutting down). The effect was to cause queues 796438032Speter to sometimes take an excessive time to flush. Reported by 796538032Speter Robert Sargent of Southern Geographics Technologies and 796638032Speter Eric Prestemon of American University. 796738032Speter Add Nice=N mailer option to set the niceness at which a mailer will 796838032Speter run. This is actually a relative niceness (that is, an 796938032Speter increment on the background value). 797038032Speter Log queue runs that are skipped due to high loads. They are logged 797138032Speter at LOG_INFO priority iff the log level is > 8. Contributed 797238032Speter by Bruce Nagel of Data General. 797338032Speter Allow the error mailer to accept a DSN-style error status code 797438032Speter instead of an sysexits status code in the host part. 797538032Speter Anything with a dot will be interpreted as a DSN-style code. 797638032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 797738032Speter to encode characters that might be munged by an EBCDIC system 797838032Speter in addition to the set required by RFC 1521. The additional 797938032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 798038032Speter (Think of "IBM 360" as the mnemonic for this flag.) 798138032Speter Change check for mailing to files to look for a pathname of [FILE] 798238032Speter rather than looking for the mailer named *file*. The mapping 798338032Speter of leading slashes still goes to the *file* mailer. This 798438032Speter allows you to implement the *file* mailer as a separate 798538032Speter program, for example, to insert a Content-Length: header 798638032Speter or do special security policy. However, note that the usual 798738032Speter initial checking for the file permissions is still done, and 798838032Speter the program in question needs to be very careful about how 798938032Speter it does the file write to avoid security problems. 799038032Speter Be able to read ~root/.forward even if the path isn't accessible to 799138032Speter regular users. This is disrecommended because sendmail 799238032Speter sometimes does not run as root (e.g., when an unsafe option 799338032Speter is specified on the command line), but should otherwise be 799438032Speter safe because .forward files must be owned by the user for 799538032Speter whom mail is being forwarded, and cannot be a symbolic link. 799638032Speter Suggested by Forrest Aldrich of Wang Laboratories. 799738032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 799838032Speter file. This is used for canonifying hostnames when the 799938032Speter service type is "files". 800038032Speter Implement programs on F (read class from file) line. The syntax is 800138032Speter Fc|/path/to/program to read the output from the program 800238032Speter into class "c". 800338032Speter Probe the network interfaces to find alternate names for this 800438032Speter host. Requires the SIOCGIFCONF ioctl call. Code 800538032Speter contributed by SunSoft. 800638032Speter Add "E" configuration line to set or propagate environment 800738032Speter variables into children. "E<envar>" will propagate 800838032Speter the named variable from the environment when sendmail 800938032Speter was invoked into any children it calls; "E<envar>=<value>" 801038032Speter sets the named variable to the indicated value. Any 801138032Speter variables not explicitly named will not be in the child 801238032Speter environment. However, sendmail still forces an 801338032Speter "AGENT=sendmail" environment variable, in part to enforce 801438032Speter at least one environment variable, since many programs and 801538032Speter libraries die horribly if this is not guaranteed. 801638032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 801738032Speter alias databases -- new algorithm looks for the substring 801838032Speter "/yp/" in the file name. This is more portable and involves 801938032Speter less overhead. Suggested by Motonori Nakamura. 802038032Speter Dynamically allocate the queue work list so that you don't lose 802138032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 802238032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 802338032Speter should not need to be changed) and the MaxQueueRunSize option, 802438032Speter which is the absolute maximum number of jobs that will ever 802538032Speter be handled in a single queue run. Based on code contributed 802638032Speter by Brian Coan of the Institute for Global Communications. 802738032Speter Log message when a message is dropped because it exceeds the maximum 802838032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 802938032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 803038032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 803138032Speter of Mark G. Thomas Consulting. 803238032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 803338032Speter OS-dependent defines). The old semantic of -d0.1 to not 803438032Speter run the daemon in background has been moved to -d99.100, 803538032Speter and the old 52.5 flag (to avoid disconnect() from closing 803638032Speter all output files) has been moved to 52.100. This makes 803738032Speter things more consistent (flags below .100 don't change 803838032Speter semantics) and separates out the backgrounding so that 803938032Speter it doesn't happen automatically on other unrelated debugging 804038032Speter flags. 804138032Speter If -t is used but no addresses are found in the header, give an 804238032Speter error message rather than just doing nothing. Fix from 804338032Speter Motonori Nakamura. 804438032Speter On systems (like SunOS) where the effective gid is not necessarily 804538032Speter included in the group list returned by getgroups(), the 804638032Speter `restrictmailq' option could sometimes cause an authorized 804738032Speter user to not be able to use `mailq'. Fix from Charles Hannum 804838032Speter of MIT. 804938032Speter Allow symbolic service names for [IPC] mailers. Suggested by 805038032Speter Gerry Magennis of Logica International. 805138032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 805238032Speter when running DNS. For example, if the name FTP.Foo.ORG is 805338032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 805438032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 805538032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 805638032Speter This is technically illegal under RFC 822 and 1123, but the 805738032Speter IETF is moving toward legalizing it. Note that turning on 805838032Speter this option is not sufficient to guarantee that a downstream 805938032Speter neighbor won't rewrite the address for you. 806038032Speter Add "-m" flag to makesendmail script -- this tells you what object 806138032Speter directory and Makefile it will use, but doesn't actually do 806238032Speter the make. 806338032Speter Do some additional checking on the contents of the qf file to try 806438032Speter to detect attacks against the qf file. In particular, 806538032Speter abort on any line beginning "From ", and add an "end of 806638032Speter file" line -- any data after that line is prohibited. 806738032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 806838032Speter choices. This can be overridden in the Makefile by using 806938032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 807038032Speter (to the extent that we know it) or by defining 807138032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 807238032Speter sendmail 8 to have more consistent installation instructions. 807338032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 807438032Speter of Sun Microsystems. 807538032Speter Improved symbol table hash function from Eric Wassenaar. This one 807638032Speter is at least 50% faster. 807738032Speter Fix problem that didn't notice that timeout on file open was a 807838032Speter transient error. Fix from Larry Parmelee of Cornell 807938032Speter University. 808038032Speter Allow comments (lines beginning with a `#') in files read for 808138032Speter classes. Suggested by Motonori Nakamura. 808238032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 808338032Speter of dropping out entirely. This makes testing some of the 808438032Speter name server lookups easier to deal with when there are 808538032Speter hung servers. From Motonori Nakamura. 808638032Speter Add new ${opMode} macro that is set to the current operation mode 808738032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 808838032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 808938032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 809038032Speter Kind of like queue-only mode (Odq) except it tries to avoid 809138032Speter any external service requests; for dial-on-demand hosts that 809238032Speter want to minimize DNS lookups when mail is being queued. For 809338032Speter this to work you will also have to make sure that gethostbyname 809438032Speter of your local host name does not do a DNS lookup. 809538032Speter Improved handling of "out of space" conditions from John Myers of 809638032Speter Carnegie Mellon. 809738032Speter Improved security for mailing to files on systems that have fchmod(2) 809838032Speter support. 809938032Speter Improve "cannot send message for N days" message -- now says "could 810038032Speter not send for past N days".

Patches 811438032Speter from Alexander Dupuy of System Management ARTS. 811538032Speter Delete duplicates in MX lists -- believe it or not, there are sites 811638032Speter that list the same host twice in an MX list. This deletion 811738032Speter only works on adjacent preferences, so an MX list that 811838032Speter had A=5, B=10, A=15 would leave both As, but one that had 811938032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 812038032Speter just in case there is something weird I haven't thought of. 812138032Speter Suggested by Barry Shein of Software Tool & Die. 812238032Speter SECURITY: .forward files cannot be symbolic links.

The semantics of this are undefined 822438032Speter for regular maps, but it can be useful for the user database. 822538032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 822638032Speter lookups while the rebuild is going on. There is a race 822738032Speter condition between the open(... O_TRUNC ...) and the lock 822838032Speter on the file, but it should be quite small. 822938032Speter SMRSH: sendmail restricted shell added to the release. This can 823038032Speter be used as an alternative to /bin/sh for the "prog" mailer, 823138032Speter giving the local administrator more control over what 823238032Speter programs can be run from sendmail. 823338032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 823438032Speter part of the release proper, and isn't fully supported; in 823538032Speter particular, it does not run on System V based systems and 823638032Speter never will. 823738032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 823838032Speter to allow rmail to compile on systems that don't have 823938032Speter function prototypes and systems that don't have snprintf. 824038032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 824138032Speter lists by transaction delay times so that addresses that 824238032Speter respond quickly get sent first. This is to prevent very 824338032Speter sluggish servers from delaying other peoples' mail. 824438032Speter Contributed by Tony Sanders of BSDI. 824538032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 824638032Speter of BSDI. This has a lot of comments to help people out. 824738032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 824838032Speter put this on the m4 command line. On GNU m4 (which 824938032Speter supports the __file__ primitive) you can run m4 in an 825038032Speter arbitrary directory -- use either: 825138032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 825238032Speter or 825338032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 825438032Speter On other versions of m4 that don't support __file__, you 825538032Speter can use: 825638032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 825738032Speter (Note the trailing slash on the _CF_DIR_ definition.) 825838032Speter Old versions of m4 will default to _CF_DIR_=.. for back 825938032Speter compatibility. 826038032Speter CONFIG: fix mail from <> so it will properly convert to 826138032Speter MAILER-DAEMON on local addresses. 826238032Speter CONFIG: fix code that was supposed to catch colons in host 826338032Speter names. Problem noted by John Gardiner Myers of CMU. 826438032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 826538032Speter From Paul Riddle of the University of Maryland, Baltimore 826638032Speter County. 826738032Speter CONFIG: Catch and reject "." as a host address. 826838032Speter CONFIG: Generalize domaintable to look up all domains, not 826938032Speter just unqualified ones. 827038032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 827138032Speter was never used and didn't work anyway. 827238032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 827338032Speter and d on all mailers in the UUCP class. 827438032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 827538032Speter look for an alias for "user+detail", then for "user+*", and 827638032Speter finally for "user". This is intended for forwarding mail 827738032Speter for system aliases such as root and postmaster to a 827838032Speter centralized hub. 827938032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 828038032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 828138032Speter The F=8 flag is also set on the "relay" mailer, since 828238032Speter this is expected to be another sendmail. 828338032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 828438032Speter the name of the UUCP_RELAY -- in some cases, this is the 828538032Speter wrong value (e.g., when we have local UUCP connections), 828638032Speter and this can create unreplyable addresses. From Chip 828738032Speter Rosenthal of Unicom. 828838032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 828964562Sgshapiro Received: header inserted into all messages. Suggested by 829038032Speter Gary Mills of the University of Manitoba. 829138032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 829243730Speter to get the old behavior. I did this upon observing 829338032Speter that almost everyone needed this feature, and that the 829438032Speter concept I was trying to make happen didn't work with 829538032Speter some user agents anyway. FEATURE(notsticky) still works, 829638032Speter but it is a no-op. 829738032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 829838032Speter names are sent, rather than immediately diagnosing them 829938032Speter as User Unknown. 830038032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 830138032Speter and RELAY_MAILER_ARGS to set the arguments for the 830238032Speter indicated mailers. All default to "IPC $h". Patch from 830338032Speter Larry Parmelee of Cornell University. 830438032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 830538032Speter on the client side" and F=P to get an appropriate 830638032Speter return-path. From Kimmo Suominen. 830738032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 830838032Speter as the local mailer. For addresses of the form "user+detail" 830938032Speter the "detail" part is passed to procmail via the -a flag. 831038032Speter Contributed by Kimmo Suominen. 831138032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 831238032Speter use from mailertables. This lets you execute arbitrary 831338032Speter procmail scripts. Contributed by Kimmo Suominen. 831438032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 831538032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 831638032Speter Paul Southworth of CICNet Systems Support. 831738032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 831838032Speter This causes the null return path to be rewritten as 831938032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 832038032Speter From Michael Hohmuth of Technische Universitat Dresden. 832138032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 832238032Speter list us as the best possible MX record to be treated as 832338032Speter though they were local (essentially, assume that they 832438032Speter are included in $=w). This can cause additional DNS 832538032Speter traffic, but is easier to administer if this fits your 832638032Speter local model. It does not work reliably if there are 832738032Speter multiple hosts that share the best MX preference. 832838032Speter Code contributed by John Oleynick of Rutgers. 832938032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 833038032Speter SHell) instead of /bin/sh as the program used for delivery 833138032Speter to programs. If an argument is included, it is used as 833238032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 833338032Speter assumed. 833438032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 833538032Speter size of messages to the local and procmail mailers 833638032Speter respectively. Contributed by Brad Knowles of the Defense 833738032Speter Information Systems Agency. 833838032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 833938032Speter (just like text outside of angle brackets) in order to 834038032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 834138032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 834238032Speter any real systems any more) and tweak the DOMAIN macro 834338032Speter so that it is less likely that users will accidentally use 834438032Speter the Berkeley defaults. Also, create some generic files 834538032Speter that really can be used in the real world. 834638032Speter CONFIG: Add new configuration macros to set character sets for 834738032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 834838032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 834938032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 835038032Speter The old name will still be accepted for a while at least. 835138032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 835238032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 835338032Speter As with all relays, it can be ``mailer:hostname''. Suggested 835438032Speter by Scott Hutton. 835538032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 835638032Speter by Barb Dijker of Labyrinth Computer Services. 835738032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 835838032Speter performance for large alias files, and this confused many 835938032Speter people. 836038032Speter CONFIG: Add confCF_VERSION to append local information to the 836138032Speter configuration version number displayed during SMTP startup. 836238032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 836338032Speter would only work when locally addressed. Fix from 836438032Speter Edvard Tuinder of Cistron Internet Services. 836538032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 836643730Speter "n" (CheckAliases) is set when rebuilding alias database. 836738032Speter Based on code contributed by Claude Marinier. 836838032Speter CONFIG: Allow mailertable to have values of the form 836938032Speter ``error:code message''. The ``code'' is a status code 837038032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 837138032Speter Contributed by David James <dwj@agw.bt.co.uk>. 837238032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 837338032Speter sender domains that will be replaced with the masquerade name. 837438032Speter These domains will not be treated as local, but if mail passes 837538032Speter through with sender addresses in those domains they will be 837638032Speter replaced by the masquerade name. These can also be specified 837738032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 837838032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 837938032Speter as well as the header. Substantial improvements to this 838038032Speter code were contributed by Per Hedeland. 838138032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 838238032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 838338032Speter by Kimmo Suominen. 838438032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 838538032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 838638032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 838738032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 838838032Speter UUCP addressing.

849964562Sgshapiro8.6.12/8.6.12 1995/03/28 850038032Speter Fix to IDENT code (it was getting the size of the reply buffer 850138032Speter too small, so nothing was ever accepted). Fix from several 850238032Speter people, including Allan Johannesen, Shane Castle of the 850338032Speter Boulder County Information Services, and Jeff Smith of 850438032Speter Warwick University (all arrived within a few hours of 850538032Speter each other!). 850638032Speter Fix a problem that could cause large jobs to run out of 850738032Speter file descriptors on systems that use vfork() rather 850838032Speter than fork(). 850938032Speter 851064562Sgshapiro8.6.11/8.6.11 1995/03/08 851138032Speter The ``possible attack'' message would be logged more often 851238032Speter than necessary if you are using Pine as a user agent. 851338032Speter The wrong host would be reported in the ``possible attack'' 851438032Speter message when attempted from IDENT. 851538032Speter In some cases the syslog buffer could be overflowed when 851638032Speter reporting the ``possible attack'' message. This can 851738032Speter cause denial of service attacks. Truncate the message 851838032Speter to 80 characters to prevent this problem. 851938032Speter When reading the IDENT response a loop is needed around the 852038032Speter read from the network to ensure that you don't get 852138032Speter partial lines. 852238032Speter Password entries without any shell listed (that is, a null 852338032Speter shell) wouldn't match as "ok". Problem noted by 852438032Speter Rob McMahon. 852538032Speter When running BIND 4.9.x a problem could occur because the 852638032Speter _res.options field is initialized differently than it 852738032Speter was historically -- this requires that sendmail call 852838032Speter res_init before it tweaks any bits. 852938032Speter Fix an incompatibility in openxscript() between the file open mode 853038032Speter and the stdio mode passed to fdopen. This caused UnixWare 853138032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 853238032Speter Novell Labs Europe. 853338032Speter Fix problem with static linking of local getopt routine when 853438032Speter using GNU's ld command. Fix from John Kennedy of 853538032Speter Cal State Chico. 853638032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 853938032Speter and Liudvikas Bukys. 854038032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 854138032Speter from Spider Boardman. 854238032Speter CONFIG: No changes (version number only, to keep it in sync 854338032Speter with the binaries). 854438032Speter 854564562Sgshapiro8.6.10/8.6.10 1995/02/10 854638032Speter SECURITY: Diagnose bogus values to some command line flags that 854738032Speter could allow trash to get into headers and qf files. 854838032Speter Validate the name of the user returned by the IDENT protocol. 854938032Speter Some systems that really dislike IDENT send intentionally 855038032Speter bogus information. Problem pointed out by Michael Bushnell 855138032Speter of the Free Software Foundation. Has some security 855238032Speter implications. 855338032Speter Fix a problem causing error messages about DNS problems when 855438032Speter the host name contained a percent sign to act oddly 855538032Speter because it was passed as a printf-style format string. 855638032Speter In some cases this could cause core dumps. 855738032Speter Avoid possible buffer overrun in returntosender() if error 855838032Speter message is quite long. From Fletcher Mattox of the 855938032Speter University of Texas. 856038032Speter Fix a problem that would silently drop "too many hops" error 856138032Speter messages if and only if you were sending to an alias. 856238032Speter From Jon Giltner of the University of Colorado and 856338032Speter Dan Harton of Oak Ridge National Laboratory. 856438032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 856538032Speter set and e->e_message was null. Fix from Bruce Nagel of 856638032Speter Data General. 856738032Speter Fix problem that can still cause df files to be left around 856838032Speter after "hop count exceeded" messages. Fix from Andrew 856938032Speter Chang and Shau-Ping Lo of SunSoft. 857038032Speter Fix a problem that can cause buffer overflows on very long 857138032Speter user names (as might occur if you piped to a program 857238032Speter with a lot of arguments). 857338032Speter Avoid returning an error and re-queueing if the host signature 857438032Speter is null; this can occur on addresses like ``user@.''. 857538032Speter Problem noted by Wesley Craig and the University of 857638032Speter Michigan. 857738032Speter Avoid possible calls to malloc(0) if MCI caching is turned 857838032Speter off. Bug fix from Pierre David of the Laboratoire 857938032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 858038032Speter Universite de Versailles - St Quentin, and Jacky 858138032Speter Thibault. 858238032Speter Make a local copy of the line being sent via senttolist() -- in 858338032Speter some cases, buffers could get trashed by map lookups 858438032Speter causing it to do unexpected things. This also simplifies 858538032Speter some of the map code. 858638032Speter CONFIG: No changes (version number only, to keep it in sync 858738032Speter with the binaries). 858838032Speter 858964562Sgshapiro8.6.9/8.6.9 1994/04/19 859038032Speter Do all mail delivery completely disconnected from any terminal. 859138032Speter This provides consistency with daemon delivery and 859238032Speter may have some security implications. 859338032Speter Make sure that malloc doesn't get called with zero size, 859438032Speter since that fails on some systems. Reported by Ed 859538032Speter Hill of the University of Iowa. 859638032Speter Fix multi-line values for $e (SMTP greeting message). Reported 859738032Speter by Mike O'Connor of Ford Motor Company. 859838032Speter Avoid syserr if no NIS domain name is defined, but the map it 859938032Speter is trying to open is optional. From Win Bent of USC. 860038032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 860138032Speter Hesiod support for UDB from Todd Miller of the University of 860238032Speter Colorado. Use "hesiod" as the service name in the U 860338032Speter option. 860438032Speter Fix a problem that failed to set the "authentic" host name (that 860538032Speter is, the one derived from the socket info) if you called 860638032Speter sendmail -bs from inetd. Based on code contributed by 860738032Speter Todd Miller (this problem was also reported by Guy Helmer 860838032Speter of Dakota State University). This also fixes a related 860938032Speter problem reported by Liudvikas Bukys of the University of 861038032Speter Rochester. 861138032Speter Parameterize "nroff -h" in all the Makefiles so people with 861238032Speter variant versions can use them easily. Suggested by 861338032Speter Peter Collinson of Hillside Systems. 861438032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 861538032Speter spaces between parameters instead of one. Reported by 861638032Speter Valdis Kletnieks of Virginia Tech. 861738032Speter Reduce the number of system calls during message collection by 861838032Speter using global timeouts around the collect() loop. This 861938032Speter code was contributed by Eric Wassenaar. 862038032Speter If the initial hostname name gathering results in a name 862138032Speter without a dot (usually caused by NIS misconfiguration) 862238032Speter and BIND is compiled in, directly access DNS to get 862338032Speter the canonical name. This should make life easier for 862438032Speter Solaris systems. If it still can't be resolved, and 862538032Speter if the name server is listed as "required", try again 862638032Speter in 30 seconds. If that also fails, exit immediately to 862738032Speter avoid bogus "config error: mail loops back to myself" 862838032Speter messages. 862938032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 863038032Speter message to explain how much space was available and 863138032Speter sound a bit less threatening. Suggested by Stan Janet 863238032Speter of the National Institute of Standards and Technology. 863338032Speter If mail is delivered to an alias that has an owner, deliver any 863438032Speter requested return-receipt immediately, and strip the 863538032Speter Return-Receipt-To: header from the subsequent message. 863638032Speter This prevents a certain class of denial of service 863738032Speter attack, arguably gives more reasonable semantics, and 863838032Speter moves things more towards what will probably become a 863938032Speter network standard. Suggested by Christopher Davis of 864038032Speter Kapor Enterprises. 864138032Speter Add a "noreceipts" privacy flag to turn off all return receipts 864238032Speter without recompiling. 864338032Speter Avoid printing ESMTP parameters as part of the error message 864438032Speter if there are errors during parsing. This change is 864538032Speter purely cosmetic. 864638032Speter Avoid sending out error messages during the collect phase of 864738032Speter SMTP; there is an MVS mailer from UCLA that gets 864838032Speter confused by this. Of course, I think it's their bug.... 864938032Speter Check for the $j macro getting undefined, losing a dot, or getting 865038032Speter lost from $=w in the daemon before accepting a connection; 865138032Speter if it is, it dumps state, prints a LOG_ALERT message, 865238032Speter and drops core for debugging. This is an attempt to 865338032Speter track down a bug that I thought was long since gone. 865438032Speter If you see this, please forward the log fragment to 865538032Speter sendmail@sendmail.ORG. 865638032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 865738032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 865838032Speter Wolfhugel. 865938032Speter Instead of trying to truncate the listen queue for the server 866038032Speter SMTP port when the load average is too high, just close 866138032Speter the port completely and reopen it later as needed. 866238032Speter This ensures that the other end gets a quick "connection 866338032Speter refused" response, and that the connection can be 866438032Speter recovered later. In particular, some socket emulations 866538032Speter seem to get confused if you tweak the listen queue 866638032Speter size around and can never start listening to connections 866738032Speter again. The down side is that someone could start up 866838032Speter another daemon process in the interim, so you could 866938032Speter have multiple daemons all not listening to connections; 867038032Speter this could in turn cause the sendmail.pid file to be 867138032Speter incorrect. A better approach might be to accept the 867238032Speter connection and give a 421 code, but that could break 867343730Speter other mailers in mysterious ways and have paging behavior 867438032Speter implications. 867538032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 867638032Speter set debugging on the wrong socket. From Eric Wassenaar. 867738032Speter When creating a df* temporary file, be sure you truncate any 867838032Speter existing data in the file -- otherwise system crashes 867938032Speter and the like could result in extra data being sent. 868038032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 868138032Speter doc directory. This includes some additional 868238032Speter information. 868338032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 868438032Speter of recipient envelope addresses. This should have been 868538032Speter handled by the $&h trick, but broke if people were 868638032Speter mixing domainized and UUCP addresses. They should 868738032Speter probably have converted all the way over to uucp-uudom 868838032Speter instead of uucp-{new,old}, but the failure mode was to 868938032Speter loop the mail, which was bad news. 869038032Speter Portability fixes: 869138032Speter Newer BSDI systems (several people). 869238032Speter Older BSDI systems from Christophe Wolfhugel. 869338032Speter Intergraph CLIX, from Paul Southworth of CICNet. 869438032Speter UnixWare, from Evan Champion. 869538032Speter NetBSD from Adam Glass. 869638032Speter Solaris from Quentin Campbell of the University of 869738032Speter Newcastle upon Tyne. 869838032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 869938032Speter Corporation. 870038032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 870138032Speter SunOS (it has setsid() and setvbuf() calls) from 870238032Speter Jonathan Kamens of OpenVision Technologies. 870338032Speter HP-UX from Tor Lillqvist. 870438032Speter New Files: 870538032Speter src/Makefile.CLIX 870638032Speter src/Makefile.NCR3000 870738032Speter doc/changes/Makefile 870838032Speter doc/changes/changes.me 870938032Speter doc/changes/changes.ps 871038032Speter 871164562Sgshapiro8.6.8/8.6.6 1994/03/21 871238032Speter SECURITY: it was possible to read any file as root using the 871338032Speter E (error message) option.

Thanks to Alain Durand of 871938032Speter INRIA for forwarding me the notice from the bugtraq 872038032Speter list. 872138032Speter 872264562Sgshapiro8.6.6/8.6.6 1994/03/13 872338032Speter SECURITY: the ability to give files away on System V-based 872438032Speter systems proved dangerous -- don't run as the owner 872538032Speter of a :include: file on a system that allows giveaways. 872638032Speter Unfortunately, this also applies to determining a 872738032Speter valid shell. 872838032Speter IMPORTANT: Previous versions weren't expiring old connections 872938032Speter in the connection cache for a long time under some 873038032Speter circumstances. This could result in resource exhaustion, 873138032Speter both at your end and at the other end. This checks the 873238032Speter connections for timeouts much more frequently. From 873338032Speter Doug Anderson of NCSC. 873438032Speter Fix a glitch that snuck in that caused programs to be run as 873538032Speter the sender instead of the recipient if the mail was 873638032Speter from a local user to another local user. From 873738032Speter Motonori Nakamura of Kyoto University. 873838032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 873938032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 874038032Speter Bryan Costales of ICSI. 874138032Speter Change the method used to declare the "statfs" availability; 874238032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 874338032Speter tweaking in conf.c, there is a single #define called 874438032Speter SFS_TYPE which takes on one of six values (SFS_NONE 874538032Speter for no statfs availability, SFS_USTAT for the ustat(2) 874638032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 874738032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 874838032Speter statfs(2) call with the declarations in <sys/vfs.h>, 874938032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 875038032Speter Fix glitch in NetInfo support that could return garbage if 875138032Speter there was no "/locations/sendmail" property. From 875238032Speter David Meyer of the University of Virginia. 875338032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 875438032Speter to allow Linux to turn it off even though it is a 875538032Speter BSD-like system. 875638032Speter Allow setting of "ident" timeout to zero to turn off the ident 875738032Speter protocol entirely. 875838032Speter Make 7-bit stripping local to a connection (instead of to a 875938032Speter mailer); this allows you to specify that SMTP is a 876038032Speter 7-bit channel, but revert to 8-bit should it advertise 876138032Speter that it supports 8BITMIME. You still have to specify 876238032Speter mailer flag 7 to get this stripping at all. 876338032Speter Improve makesendmail script so it handles more cases automatically. 876438032Speter Tighten up restrictions on taking ownership of :include: files 876538032Speter to avoid problems on systems that allow you to give away 876638032Speter files. 876738032Speter Fix a problem that made it impossible to rebuild the alias 876838032Speter file if it was on a read-only file system. From 876938032Speter Harry Edmon of the University of Washington. 877038032Speter Improve MX randomization function. From John Gardiner Myers 877138032Speter of CMU. 877238032Speter Fix a minor glitch causing a bogus message to be printed (used 877338032Speter %s instead of %d in a printf string for the line number) 877438032Speter when a bad queue file was read. From Harry Edmon. 877538032Speter Allow $s to remain NULL on locally generated mail. I'm not 877638032Speter sure this is necessary, but a lot of people have complained 877738032Speter about it, and there is a legitimate question as to whether 877838032Speter "localhost" is legal as an 822-style domain. 877938032Speter Fix a problem with very short line lengths (mailer L= flag) in 878038032Speter headers. This causes a leading space to be added onto 878138032Speter continuation lines (including in the body!), and also 878238032Speter tries to wrap headers containing addresses (From:, To:, 878338032Speter etc) intelligently at the shorter line lengths. Problem 878438032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 878538032Speter Log the real user name when logging syserrs, since these can have 878638032Speter security implications. Suggested by several people. 878738032Speter Fix address logging of cached connections -- it used to always 878838032Speter log the numeric address as zero. This is a somewhat 878938032Speter bogus implementation in that it does an extra system 879038032Speter call, but it should be an inexpensive one. Fix from 879138032Speter Motonori Nakamura. 879238032Speter Tighten up handling of short syslog buffers even more -- there 879338032Speter were cases where the outgoing relay= name was too long 879438032Speter to share a line with delay= and mailer= logging. 879538032Speter Limit the overhead on split envelopes to one open file descriptor 879638032Speter per envelope -- previously the overhead was three 879738032Speter descriptors. This was in response to a problem reported 879838032Speter by P{r (Pell) Emanuelsson. 879938032Speter Fixes to better handle the case of unexpected connection closes; 880038032Speter this redirects the output to the transcript so the info 880138032Speter is not lost. From Eric Wassenaar. 880238032Speter Fix potential string overrun if you macro evaluate a string that 880338032Speter has a naked $ at the end. Problem noted by James Matheson 880438032Speter <jmrm@eng.cam.ac.uk>. 880538032Speter Make default error number on $#error messages 553 (``Requested 880638032Speter action not taken: mailbox name not allowed'') instead of 880738032Speter 501 (``Syntax error in parameters or arguments'') to 880838032Speter avoid bogus "protocol error" messages. 880938032Speter Strip off any existing trailing dot on names during $[ ... $] 881038032Speter lookup. This prevents it from ending up with two dots 881138032Speter on the end of dot terminated names. From Wesley Craig 881238032Speter of the University of Michigan and Bryan Costales of ICSI. 881338032Speter Clean up file class reading so that the debugging information is 881438032Speter more informative. It hadn't been using setclass, so you 881538032Speter didn't see the class items being added. 881638032Speter Avoid core dump if you are running a version of sendmail where 881738032Speter NIS is compiled in, and you specify an NIS map, but 881838032Speter NIS is not running. Fix from John Oleynick of 881938032Speter Rutgers. 882038032Speter Diagnose bizarre case where res_search returns a failure value, 882138032Speter but sets h_errno to a success value. 882238032Speter Make sure that "too many hops" messages are considered important 882338032Speter enough to send an error to the Postmaster (that is, the 882438032Speter address specified in the P option). This fix should 882538032Speter help problems that cause the df file to be left around 882638032Speter sometimes -- unfortunately, I can't seem to reproduce 882738032Speter the problem myself. 882838032Speter Avoid core dump (null pointer reference) on EXPN command; this 882938032Speter only occurred if your log level was set to 10 or higher 883038032Speter and the target account was an alias or had a .forward file. 883138032Speter Problem noted by Janne Himanka. 883238032Speter Avoid "denial of service" attacks by someone who is flooding your 883338032Speter SMTP port with bad commands by shutting the connection 883438032Speter after 25 bad commands are issued. From Kyle Jones of 883538032Speter UUNET. 883638032Speter Fix core dump on error messages with very long "to" buffers; 883738032Speter fmtmsg overflows the message buffer. Fixed by trimming 883838032Speter the to address to 203 characters. Problem reported by 883938032Speter John Oleynick. 884038032Speter Fix configuration for HASFLOCK -- there were some spots where 884138032Speter a #ifndef was incorrectly #ifdef. Pointed out by 884238032Speter George Baltz of the University of Maryland. 884338032Speter Fix a typo in savemail() that could cause the error message To: 884438032Speter lists to be incorrect in some places. From Motonori 884538032Speter Nakamura. 884638032Speter Fix a glitch that can cause duplicate error messages on split 884738032Speter envelopes where an address on one of the lists has a 884838032Speter name server failure. Fix from Voradesh Yenbut of the 884938032Speter University of Washington. 885038032Speter Fix possible bogus pointer reference on ESMTP parameters that 885138032Speter don't have an ``=value'' part. 885238032Speter CNAME loops caused an error message to be generated, but also 885338032Speter re-queued the message. Changed to just re-queue the 885438032Speter message (it's really hard to just bounce it because 885538032Speter of the weird way the name server works in the presence 885638032Speter of CNAME loops). Problem noted by James M.R.Matheson 885738032Speter of Cambridge University. 885838032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 885938032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 886038032Speter user name. Suggested by Andreas Stolcke of ICSI. 886138032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 886238032Speter override it easily in the Makefile -- that is, you can 886338032Speter turn it off using -DNAMED_BIND=0. 886438032Speter If a gethostbyname(...) of an address with a trailing dot fails, 886538032Speter try it without the trailing dot. This is because if 886638032Speter you have a version of gethostbyname() that falls back 886738032Speter to NIS or the /etc/hosts file it will fail to find 886838032Speter perfectly reasonable names that just don't happen to 886938032Speter be dot terminated in the hosts file. You don't want to 887038032Speter strip the dot first though because we're trying to ensure 887138032Speter that country names that match one of your subdomains get 887238032Speter a chance. 887338032Speter PRALIASES: fix bogus output on non-null-terminated strings. 887438032Speter From Bill Gianopoulos of Raytheon. 887538032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 887638032Speter This was in code intended to only catch the self-literal 887738032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 887838032Speter IP address), but the code was broken. However, it will 887938032Speter still do this if $M is defined; this is necessary to 888038032Speter get client configurations to work (sigh). Note that this 888138032Speter means that $M overrides :mailname entries in the user 888238032Speter database! Problem noted by Paul Southworth. 888338032Speter CONFIG: Fix definition of Solaris help file location. From 888438032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 888538032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 888638032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 888738032Speter and USENET_MAILER_MAX to tweak the maximum message 888838032Speter size for various mailers. 888938032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 889038032Speter instead of assuming that it is "inews" for consistency 889138032Speter with other mailers. From Michael Corrigan of UC San Diego. 889238032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 889338032Speter qualify the address in the SMTP envelope as user@{relay|hub} 889438032Speter instead of user@$j. From Bill Wisner of The Well. 889538032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 889638032Speter CONFIG: Don't turn off case mapping of user names in the local 889738032Speter mailer for IRIX. This was different than most every other 889838032Speter system. 889938032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 890038032Speter envelope. Noted by Thierry Besancon 890138032Speter <besancon@excalibur.ens.fr>. 890238032Speter CONFIG: Don't include -z by default on uux line -- most systems 890338032Speter don't want it set by default. Pointed out by Philippe 890438032Speter Michel of Thomson CSF. 890538032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 890638032Speter host name was foo.bar.ray.com and you matched against 890738032Speter ".ray.com", the old implementation bound %1 to "bar" 890838032Speter instead of "foo.bar". Also, allow "." in the mailertable 890938032Speter to match anything -- essentially, take over SMART_HOST. 891038032Speter This also moves matching of explicit local host names 891138032Speter before the mailertable so they don't have to be special 891238032Speter cased in the mailertable data. Reported by Bill 891338032Speter Gianopoulos of Raytheon; the fix for the %1 binding 891438032Speter problem was contributed by Nicholas Comanos of the 891538032Speter University of Sydney. 891638032Speter CONFIG: Don't include "root" in class $=L (users to deliver 891738032Speter locally, even if a hub or relay exists) by default. 891838032Speter This is because of the known bug where definition of 891938032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 892038032Speter both and deliver into the local mailbox. 892138032Speter CONFIG: Move up bitdomain and uudomain handling so that they 892238032Speter are done before .UUCP class matching; uudomain was 892338032Speter reported as ineffective before. This also frees up 892438032Speter diversion 8 for future use. Problem reported by Kimmo 892538032Speter Suominen. 892638032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 892738032Speter into host names. As pointed out by Jonathan Kamens, 892838032Speter these are often used because either the forward or reverse 892938032Speter mapping is broken; this translation makes it broken again. 893038032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 893138032Speter Suominen. 893238032Speter Portability fixes: 893338032Speter Unicos from David L.

From 895738032Speter Bob Campbell at U.C. Berkeley. 895838032Speter Security fix: group ids were not completely set when programs 895938032Speter were invoked. This caused programs to have group 896038032Speter permissions they should not have had (usually group 896138032Speter daemon instead of their own group). In particular, 896238032Speter Perl scripts would refuse to run. 896338032Speter Security: check to make sure files that are written are not 896438032Speter symbolic links (at least under some circumstances). 896538032Speter Although this does not respond to a specific known 896638032Speter attack, it's just a good idea. Suggested by 896738032Speter Christian Wettergren. 896838032Speter Security fix: if a user had an NFS mounted home directory on 896938032Speter a system with a restricted shell listed in their 897038032Speter /etc/passwd entry, they could still execute any 897138032Speter program by putting that in their .forward file. 897238032Speter This fix prevents that by insisting that their shell 897338032Speter appear in /etc/shells before allowing a .forward to 897438032Speter execute a program or write a file. You can disable 897538032Speter this by putting "*" in /etc/shells. It also won't 897638032Speter permit world-writable :include: files to reference 897738032Speter programs or files (there's no way to disable this). 897843730Speter These behaviors are only one level deep -- for 897938032Speter example, it is legal for a world-writable :include: 898038032Speter file to reference an alias that writes a file, on 898138032Speter the assumption that the alias file is well controlled. 898238032Speter Security fix: root was not treated suspiciously enough when 898338032Speter looking into subdirectories. This would potentially 898438032Speter allow a cracker to examine files that were publicly 898538032Speter readable but in a non-publicly searchable directory. 898638032Speter Fix a problem that causes an error on QUIT on a cached 898738032Speter connection to create problems on the current job. 898838032Speter These are typically unrelated, so errors occur in 898938032Speter the wrong place. 899038032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 899138032Speter runs more responsive to load average, and fixes a 899238032Speter problem that ignored the load average in locally 899338032Speter generated mail. From Eric Wassenaar. 899438032Speter Fix possible core dump on aliases with null LHS. From 899538032Speter John Orthoefer of BB&N. 899638032Speter Revert to using flock() whenever possible -- there are just 899738032Speter too many bugs in fcntl() locking, particularly over 899838032Speter NFS, that cause sendmail to fail in perverse ways. 899938032Speter Fix a bug that causes the connection cache to get confused 900038032Speter when sending error messages. This resulted in 900138032Speter "unexpected close" messages. It should fix itself 900238032Speter on the following queue run. Problem noted by 900338032Speter Liudvikas Bukys of the University of Rochester. 900438032Speter Include $k in $=k as documented in the Install & Op Guide. 900538032Speter This seems odd, but it was documented.... From 900638032Speter Michael Corrigan of UCSD. 900738032Speter Fix problem that caused :include:s from alias files to be 900838032Speter forced to be owned by root instead of daemon 900938032Speter (actually DefUid). From Tim Irvin. 901038032Speter Diagnose unrecognized I option values -- from Mortin Forssen 901138032Speter of the Chalmers University of Technology. 901238032Speter Make "error" mailer work consistently when there is no error 901338032Speter code associated with it -- previously it returned OK 901438032Speter even though there was a real problem. Now it assumes 901538032Speter EX_UNAVAILABLE. 901638032Speter Fix bug that caused the last header line of messages that had 901738032Speter no body and which were terminated with EOF instead of 901838032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 901938032Speter Fix core dump on SMTP mail to programs that failed -- it tried 902038032Speter to go to a "next MX host" when none existed, causing 902138032Speter a core dump. From der Mouse at McGill University. 902238032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 902338032Speter this makes it easier to turn it off (using 902438032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 902538032Speter Fix YP_MASTER_NAME store to use the unupdated result of 902638032Speter gethostname() (instead of myhostname(), which tries 902738032Speter to fully qualify the name) to be consistent with 902838032Speter SunOS. If your hostname is unqualified, this fixes 902938032Speter transfers to slave servers. Bug noted by Keith 903038032Speter McMillan of Ameritech Services, Inc. 903138032Speter Fix Ultrix problem: gethostbyname() can return a very large 903238032Speter (> 500) h_length field, which causes the sockaddr 903338032Speter to be trashed. Use the size of the sockaddr instead. 903438032Speter Fix from Bob Manson of Ohio State. 903538032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 903638032Speter defined -- this confuses gethostbyname on hosts 903738032Speter file lookups, which doesn't understand the trailing 903838032Speter dot convention. 903938032Speter Log SMTP server subprocesses that die with a signal instead 904038032Speter of from a clean exit. 904138032Speter If you don't have option "I" set, don't assume that a DNS 904238032Speter "host unknown" message is authoritative -- it 904338032Speter might still be found in /etc/hosts. 904438032Speter Fix a problem that would cause Deferred: messages to be sent 904538032Speter as the subject of an error message, even though the 904638032Speter actual cause of a message was more severe than that. 904738032Speter Problem noted by Chris Seabrook of OSSI. 904838032Speter Fix race condition in DBM alias file locking. From Kyle 904938032Speter Jones of UUNET. 905038032Speter Limit delivery syslog line length to avoid bugs in some 905138032Speter versions of syslog(3). This adds a new compile time 905238032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 905338032Speter University, which is in turn derived from IDA. 905438032Speter Fix quotes inside of comments in addresses -- previously 905538032Speter it insisted that they be balanced, but the 822 spec 905638032Speter says that they should be ignored. 905738032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 905838032Speter debugging). This also evaluates ruleset 89, if set 905938032Speter (with the null input), and logs the result. This 906038032Speter should be used sparingly, since the rewrite process 906138032Speter is not reentrant. 906238032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 906338032Speter documented in the Bat Book. 906438032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 906538032Speter return an error message and did not requeue the message. 906638032Speter Fix based on code from Roland Dirlewanger of 906738032Speter Reseau Regional Aquarel, Bordeaux, France. 906838032Speter Fix a problem that caused a seg fault if you got a 421 error 906938032Speter code during some parts of connection initialization. 907038032Speter I've only seen this when talking to buggy mailers on 907138032Speter the other end, but it shouldn't give a seg fault in 907238032Speter any case. From Amir Plivatsky. 907338032Speter Fix core dump caused by a ruleset call that returns null. 907438032Speter Fix from Bryan Costales of ICSI. 907538032Speter Full-Name: field was being ignored.

Suggested by 908238032Speter Bryan Costales. 908338032Speter Initialize non-alias maps during alias rebuilds -- they may be 908438032Speter needed for parsing. Problem noted by Douglas Anderson. 908538032Speter Log sender address even if no message was collected in SMTP 908638032Speter (e.g., if all RCPTs failed). Suggested by Motonori 908738032Speter Nakamura. 908838032Speter Don't reflect the owner-list contents into the envelope sender 908938032Speter address if the value contains ", :, /, or | (to avoid 909038032Speter illegal addresses appearing there). 909138032Speter Efficiency hack for toktype macro -- from Craig Partridge of 909238032Speter BB&N. 909338032Speter Clean up DNS error printing so that a host name is always 909438032Speter included. 909538032Speter Remember to set $i during queue runs. Reported by Stephen 909638032Speter Campbell of Dartmouth University. 909738032Speter If the environment variable HOSTALIASES is set, use it during 909838032Speter canonification as the name of a file with per-user host 909938032Speter translations so that headers are properly mapped. Reported 910038032Speter by Anne Bennett of Concordia University. 910138032Speter Avoid printing misleading error message if SMTP mailer (not 910238032Speter using [IPC]) should die on a core dump. 910338032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 910438032Speter by the other end closing the connection. From 910538032Speter Dave Morrison of Oracle. 910638032Speter Improve several of the error messages printed by "mailq" 910738032Speter to include a host name or other useful information. 910838032Speter Add NetInfo preliminary support for NeXT systems. From Vince 910938032Speter DeMarco. 911038032Speter Fix a glitch that sometimes caused :include:s that pointed to 911138032Speter NFS filesystems that were down to give an "aliasing/ 911238032Speter forwarding loop broken" message instead of queueing 911338032Speter the message for retry. Noted by William C Fenner of 911438032Speter the NRL Connection Machine Facility. 911538032Speter Fix a problem that could cause a core dump if the input sequence 911638032Speter had (or somehow acquired) a \231 character. 911738032Speter Make sure that route-addrs always have <angle brackets> around 911838032Speter them in non-SMTP envelopes (SMTP envelopes already do 911938032Speter this properly). 912038032Speter Avoid weird headers on unbalanced punctuation of the form: 912138032Speter ``Joe User <user)'' -- this caused reference to the 912238032Speter null macro. Fix from Rick McCarty of IO.COM. 912338032Speter Fix a problem that caused an alias "user: user@local.host" to 912438032Speter not have the QNOTREMOTE bit set; this caused configs 912538032Speter to act as if FEATURE(notsticky) was defined even when 912638032Speter it was not. The effect of the problem was to make it 912738032Speter very hard to to set up satellite sites that had a few 912838032Speter local accounts, with everything else forwarded to a 912938032Speter corporate hub. Reported by Detlef Drewanz of the 913038032Speter University of Rostock and Mark Frost of NCD. 913138032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 913238032Speter addresses. This is more efficient (fewer name server 913338032Speter calls) and fixes certain unusual configurations, such 913438032Speter as those that have ruleset 4 do something that is 913538032Speter non-idempotent unless a mailer-specific ruleset did 913638032Speter something else. Problem reported by Brian J. Coan 913738032Speter of the Institute for Global Communications. 913838032Speter Fix the "obsolete argument" routine in main to better understand 913938032Speter new arguments. For example, if you used ``sendmail 914038032Speter -C config -v -q'' it would choke on the -q because 914138032Speter the -C would stop looking for old-format arguments. 914238032Speter Fix the code that was intended to allow two users to forward their 914338032Speter mail to the same program and have them appear unique. 914438032Speter Portability fixes for: 914538032Speter SCO UNIX from Murray Kucherawy. 914638032Speter SCO Open Server 3.2v4 from Philippe Brand. 914738032Speter System V Release 4 from Rick Ellis and others. 914838032Speter OSF/1 from Steve Campbell. 914938032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 915038032Speter of Stoner Associates. 915138032Speter Motorola SysV88 from Kevin Johnson of Motorola. 915238032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 916638032Speter of the config file has moved to /usr/lib 916738032Speter to match the HP-UX version of sendmail. 916838032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 916938032Speter since this is intended only for internal use, the 917038032Speter usual RFC 821/822/1123 rules can be relaxed. The 917138032Speter main point of this is to avoid munging (ugh) UUCP 917238032Speter addresses when relaying internally. 917338032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 917438032Speter syntax addresses delivered via UUCP. Solution 917538032Speter provided by Peter Wemm. 917638032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 917738032Speter zero; it caused double @ signs in addresses. From 917838032Speter Irving Reid of the University of Toronto. 917938032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 918038032Speter from Markku Toijala of ICL Personal Systems Oy. 918138032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 918238032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 918338032Speter that made it hard to recognize your own pseudodomain 918438032Speter names. 918538032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 918638032Speter rather than letting them get "local configuration 918738032Speter error"s. Problem noted by John Gardiner Myers. 918838032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 918938032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 919038032Speter has uucp-dom semantics but old UUCP syntax. This 919138032Speter also permits "uucp-old" as an alias for "uucp" and 919238032Speter "uucp-new" as a synonym for "suucp" for consistency. 919338032Speter CONFIG: add POP mailer support (from Kimmo Suominen 919438032Speter <kim@grendel.lut.fi>). 919538032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 919638032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 919738032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 919838032Speter was set; it would get an additional @masquerade.host 919938032Speter added to the address. Problem noted by Peter Wan 920038032Speter of Georgia Tech. 920138032Speter CONFIG: make sure that the local UUCP name is in $=w. From 920238032Speter Jim Murray of Stratus. 920338032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 920438032Speter mailer flag. Briefly, if you are sending to host 920538032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 920638032Speter "foo!baz" remains "foo!baz", and anything else has 920738032Speter the local name prepended. 920838032Speter CONFIG: portability fixes for HP-UX. 920938032Speter DOC: several minor problems fixed in the Install & Op Guide. 921038032Speter MAKEMAP: fix core dump problem on lines that are too long or 921138032Speter which lack newline. From Mark Delany. 921238032Speter MAILSTATS: print sums of columns (total messages & kbytes 921338032Speter in and out of the system). From Tom Ferrin of UC 921438032Speter San Francisco Computer Graphics Lab. 921538032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 921638032Speter On HP-UX, /etc/sendmail.cf has been moved to 921738032Speter /usr/lib/sendmail.cf to match HP sendmail. 921838032Speter Permissions have been tightened up on world-writable 921938032Speter :include: files and accounts that have shells 922038032Speter that are not listed in /etc/shells. This may 922138032Speter cause some .forward files that have worked 922238032Speter before to start failing. 922338032Speter SIGUSR1 dumps some state to the log. 922438032Speter NEW FILES: 922538032Speter src/Makefile.DGUX 922638032Speter src/Makefile.Dynix 922738032Speter src/Makefile.FreeBSD 922838032Speter src/Makefile.Mach386 922938032Speter src/Makefile.NetBSD 923038032Speter src/Makefile.RISCos 923138032Speter src/Makefile.SCO 923238032Speter src/Makefile.SVR4 923338032Speter src/Makefile.Titan 923438032Speter cf/mailer/pop.m4 923538032Speter cf/ostype/bsdi1.0.m4 923638032Speter cf/ostype/dgux.m4 923738032Speter cf/ostype/dynix3.2.m4 923838032Speter cf/ostype/sco3.2.m4 923938032Speter makemap/Makefile.dist 924038032Speter praliases/Makefile.dist 924138032Speter 924264562Sgshapiro8.6.4/8.6.4 1993/10/31 924338032Speter Repair core-dump problem (write to read-only memory segment) 924438032Speter if you fall back to the return-to-Postmaster case in 924538032Speter savemail. Problem reported by Richard Liu. 924638032Speter Immediately diagnose bogus sender addresses in SMTP. This 924738032Speter makes quite certain that crackers can't use this 924838032Speter class of attack. 924938032Speter Reliability Fix: check return value from fclose() and fsync() 925038032Speter in a few critical places. 925138032Speter Minor problem in initsys() that reversed a condition for 925238032Speter redirecting the output channel on queue runs. It's 925338032Speter not clear this code even does anything. From Eric 925438032Speter Wassenaar of the Dutch National Institute for Nuclear 925538032Speter and High-Energy Physics. 925638032Speter Fix some problems that caused queue runs to do "too much work", 925738032Speter such as double-reading the Errors-To: header. From 925838032Speter Eric Wassenaar. 925938032Speter Error messages on writing the temporary file (including the 926038032Speter data file) were getting suppressed in SMTP -- this 926138032Speter fix causes them to be properly reported. From Eric 926238032Speter Wassenaar. 926338032Speter Some changes to support AF_UNIX sockets -- this will only 926438032Speter really become relevant in the next release, but some 926538032Speter people need it for local patches. From Michael 926638032Speter Corrigan of UC San Diego. 926738032Speter Use dynamically allocated memory (instead of static buffers) 926838032Speter for macros defined in initsys() and settime(); since 926938032Speter these can have different values depending on which 927038032Speter envelope they are in. From Eric Wassenaar. 927138032Speter Improve logging to show ctladdr on to= logging; this tells you 927238032Speter what uid/gid processes ran as. 927338032Speter Fix a problem that caused error messages to be discarded if 927438032Speter the sender address was unparseable for some reason; 927538032Speter this was supposed to fall back to the "return to 927638032Speter postmaster" case. 927738032Speter Improve aliaswait backoff algorithm. 927838032Speter Portability patches for Linux (8.6.3 required another header 927938032Speter file) (from Karl London) and SCO UNIX. 928038032Speter CONFIG: patch prog mailer to not strip host name off of envelope 928138032Speter addresses (so that it matches local again). From 928238032Speter Christopher Davis. 928338032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 928438032Speter this prevents uux from seeing lines with null names like 928538032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 928638032Speter Nakamura of Kyoto University. 928738032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 928838032Speter it shouldn't fail miserably. From Motonori Nakamura. 928938032Speter 929064562Sgshapiro8.6.2/8.6.2 1993/10/15 929138032Speter Put a "successful delivery" message in the transcript for 929238032Speter addresses that get return-receipts. 929338032Speter Put a prominent "this is only a warning" message in warning 929438032Speter messages -- some people don't read carefully enough 929538032Speter and end up sending the message several times. 929638032Speter Include reason for temporary failure in the "warning" return 929738032Speter message. Currently, it just says "cannot send for 929838032Speter four hours". 929938032Speter Fix the "Original message received" time generated for 930038032Speter returntosender messages. It was previously listed as 930138032Speter the current time. Bug reported by Eric Hagberg of 930238032Speter Cornell University Medical College. 930338032Speter If there is an error when writing the body of a message, 930438032Speter don't send the trailing dot and wait for a response 930538032Speter in sender SMTP, as this could cause the connection to 930638032Speter hang up under some bizarre circumstances. From Eric 930738032Speter Wassenaar. 930838032Speter Fix some server SMTP synchronization problems caused when 930938032Speter connections fail during message collection. From 931038032Speter Eric Wassenaar. 931138032Speter Fix a problem that can cause srvrsmtp to reject mail if the 931238032Speter name server is down -- it accepts the RCPT but rejects 931338032Speter the DATA command. Problem reported by Jim Murray of 931438032Speter Stratus. 931538032Speter Fix a problem that can cause core dumps if the config file 931638032Speter incorrectly resolves to a null hostname. Reported by 931738032Speter Allan Johannesen of WPI. 931838032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 931938032Speter by non-root users were not put into 932038032Speter X-Authentication-Warning:s as intended because the 932143730Speter config file hadn't set the PrivacyOptions yet. Fix 932238032Speter from Sven-Ove Westberg of the University of Lulea. 932338032Speter Under very odd circumstances, the alias file rebuild code 932438032Speter could get confused as to whether a database was 932538032Speter open or not. 932638032Speter Check "vendor code" on the end of V lines -- this is 932738032Speter intended to provide a hook for vendor-specific 932838032Speter configuration syntax. (This is a "new feature", 932938032Speter but I've made an exception to my rule in a belief 933038032Speter that this is a highly exceptional case.) 933138032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 933238032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 933338032Speter (from Jon Forrest of UC Berkeley) 933438032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 933538032Speter 933664562Sgshapiro8.6.1/8.6 1993/10/08 933738032Speter Portability fixes for A/UX and Encore UMAX V. 933838032Speter Fix error message handling -- if you had a name server down 933938032Speter causing an error during parsing, that message was never 934038032Speter propagated to the queue file. 934138032Speter 934264562Sgshapiro8.6/8.6 1993/10/05 934338032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 934438032Speter conf.h (other systems have the same bug). 934538032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 934638032Speter getdtablesize() instead of sysconf(); a disturbingly 934738032Speter large number of systems defined _SC_OPEN_MAX in the 934838032Speter header files but don't have the syscall. 934938032Speter Another patch to really truly ignore MX records in getcanonname 935038032Speter if trymx == FALSE. 935138032Speter Fix problem that caused the "250 IAA25499 Message accepted for 935238032Speter delivery" message to be omitted if there was an error 935338032Speter in the header of the message (e.g., a bad Errors-To: 935438032Speter line). Pointed out by Michael Corrigan of UCSD. 935538032Speter Announce name of host we are chatting when we get errors; this 935638032Speter is an IDA-ism suggested by Christophe Wolfhugel. 935738032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 935838032Speter Australian Artificial Intelligence Institute), SCO Unix 935938032Speter (from Murray Kucherawy of Hookup Communication Corp.), 936038032Speter NeXT (from Vince DeMarco and myself), Linux (from 936138032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 936238032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 936338032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 936438032Speter Some changes to get around gcc optimizer bugs. From Takahiro 936538032Speter Kanbe. 936638032Speter Fix error recovery in queueup if another tf file of the same 936738032Speter name already exists. Problem stumbled over by Bill 936838032Speter Wisner of The Well. 936938032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 937038032Speter Problem noted by Keith McMillan of Ameritech Services. 937138032Speter Deal with group permissions properly when opening .forward and 937238032Speter :include: files. This relaxes the 8.1C restrictions 937338032Speter slightly more. This includes proper setting of groups 937438032Speter when reading :include: files, allowing you to read some 937538032Speter files that you should be able to read but have previously 937638032Speter been denied unless you owned them or they had "other" 937738032Speter read permission. 937838032Speter Make certain that $j is in $=w (after the .cf is read) so that 937938032Speter if the user is forced to override some silly system, 938038032Speter MX suppression will still work. 938138032Speter Fix a couple of efficiency problems where newstr was double- 938238032Speter calling expensive routines. In at least one case, it 938338032Speter wasn't guaranteed that they would always return the 938438032Speter same result. Problem noted by Christophe Wolfhugel. 938538032Speter Fix null pointer dereference in putoutmsg -- only on an error 938638032Speter condition from a non-SMTP mailer. From Motonori 938738032Speter Nakamura. 938838032Speter Macro expand "C" line class definitions before scanning so that 938938032Speter "CX $Z" works. 939038032Speter Fix problem that caused error message to be sent while still 939138032Speter trying to send the original message if the connection 939238032Speter is closed during a DATA command after getting an error 939338032Speter on an RCPT command (pretty obscure). Problem reported 939438032Speter by John Myers of CMU. 939538032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 939638032Speter term bug. 939738032Speter Fix a nasty bug causing core dumps when returning the "warning: 939838032Speter cannot deliver for N hours -- will keep trying" message; 939943730Speter it only occurred if you had PostmasterCopy set and 940038032Speter only on some architectures. Although sendmail would 940138032Speter keep trying, it would send error messages on each 940238032Speter queue interval. This is an important fix. 940338032Speter Allow u and g options to take user and group names respectively. 940438032Speter Don't do a chdir into the queue directory in -bt mode to make 940538032Speter ruleset testing a bit easier. 940638032Speter Don't allow users to turn off logging (using -oL) on the command 940738032Speter line -- command line can only raise, not lower, logging 940838032Speter level. 940938032Speter Set $u to the original recipient on the SMTP transaction or on 941038032Speter the command line. This is only done if there is exactly 941138032Speter one recipient. Technically, this does not meet the 941238032Speter specs, because it does not guarantee a domain on the 941338032Speter address. 941438032Speter Fix a problem that dumped error messages on bad addresses if 941538032Speter you used the -t flag. Problem noted by Josh Smith of 941638032Speter Harvey Mudd College. 941738032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 941838032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 941938032Speter avoid the problem of people who use angle brackets in 942038032Speter their full name information. 942138032Speter Fix a null pointer dereference if you set option "l", have 942238032Speter an Errors-To: header in the message, and have Errors-To: 942338032Speter defined in the config file H lines. From J.R. Oldroyd. 942438032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 942538032Speter wrong when compiling. Suggested by Rick McCarty of TI. 942638032Speter Fix a problem that could pass negative SIZE parameter if the 942738032Speter df file got lost; this would cause servers to always 942838032Speter give a temporary failure, making the problem even worse. 942938032Speter Problem noted by Allan Johannesen of WPI. 943038032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 943138032Speter protocol timeouts (30s default). Requested by Murray 943238032Speter Kucherawy of HookUp Communication Corp. to handle bogus 943338032Speter PC TCP/IP implementations. 943438032Speter Change $w default definition to be just the first component of 943538032Speter the domain name on config level 5. The $j macro defaults 943638032Speter to the FQDN; $m remains as before. This lets well-behaved 943738032Speter config files use any of the short, long, or subdomain 943838032Speter names. 943938032Speter Add makesendmail script in src to try to automate multi-architecture 944038032Speter builds. I know, this is sub-optimal, but it is still 944138032Speter helpful. 944238032Speter Fix very obscure race condition that can cause a queue run to 944338032Speter get a queue file for an already completed job. This 944438032Speter problem has existed for years. Problem noted by the 944538032Speter long suffering Allan Johannesen of WPI. 944638032Speter Fix a problem that caused the raw sender name to be passed to 944738032Speter udbsender instead of the canonified name -- this caused 944838032Speter it to sometimes miss records that it should have found. 944938032Speter Relax check of name on HELO packet so that a program using -bs 945038032Speter that claims to be itself works properly. 945138032Speter Restore rewriting of $: part of address through 2, R, 4 in 945238032Speter buildaddr -- this requires passing a lot of flags to get 945338032Speter it right. Unlike old versions, this ONLY rewrites 945438032Speter recipient addresses, not sender addresses. 945538032Speter Fix a bug that caused core dumps in config files that cannot 945638032Speter resolve /file/name style addresses. Fix from Jonathan 945738032Speter Kamens of OpenVision Technologies. 945838032Speter Fix problem with fcntl locking that can cause error returns to 945938032Speter be lost if the lock is lost; this required fully 946038032Speter queueing everything, dropping the envelope (so errors 946138032Speter would get returned), and then re-reading the queue from 946238032Speter scratch. 946338032Speter Fix a problem that caused aliases that redefine an otherwise 946438032Speter true address to still send to the original address 946538032Speter if and only if the alias failed in certain bizarre 946638032Speter ways (e.g, if they pointed at a list:; syntax address). 946738032Speter Problem pointed out by Jonathan Kamens. 946838032Speter Remove support for frozen configuration files. They caused 946938032Speter more trouble than it was worth. 947038032Speter Fix problem that can cause error messages to get ignored when 947138032Speter using both -odb and -t flags. Problem noted by Rob 947238032Speter McNicholas at U.C. Berkeley. 947338032Speter Include all "normal" variations on hostname in $=w. For example, 947438032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 947538032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 947638032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 947738032Speter the queue. 947838032Speter Reset SmtpPhase global on initial connection creation so that 947938032Speter messages don't come out with stale information. 948038032Speter Pass an "ext" argument to lockfile so that error/log messages 948138032Speter will properly reflect the true filename being locked. 948238032Speter Put all [...] address forms into $=w -- this eliminates the need 948338032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 948438032Speter Myers of CMU. 948538032Speter Fix a bug that can cause qf files to be left around even after 948638032Speter an SMTP RSET command. Problem and fix from Michael 948738032Speter Corrigan. 948843730Speter Don't send a PostmasterCopy to errors when the Precedence: is 948938032Speter negative. Error reports still go to the envelope 949038032Speter sender address. 949138032Speter Add LA_SHORT for load averages. 949238032Speter Lock sendmail.st file when posting statistics. 949338032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 949438032Speter set the size of the TCP send and receive buffers; if you 949538032Speter run over a slow slip line you may need to set these down 949638032Speter (although it would be better to fix the SLIP implementation 949738032Speter so that it's not necessary to recompile every program 949838032Speter that does bulk data transfer). 949938032Speter Allow null defaults on $( ... $) lookups. Problem reported by 950038032Speter Amir Plivatsky. 950138032Speter Diagnose crufty S and V config lines. This resulted from an 950238032Speter observation that some people were using the SITE macro 950338032Speter without the SITECONFIG macro first, which was causing 950438032Speter bogus config files that were not caught. 950538032Speter Fix makemap -f flag to turn off case folding (it was turning it 950638032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 950738032Speter Fix a problem that caused multiple error messages to be sent if 950838032Speter you used "sendmail -t -oem -odb", your system uses fcntl 950938032Speter locking, and one of the recipient addresses is unknown. 951038032Speter Reset uid earlier in include() so that recursive .forwards or 951138032Speter :include:s don't use the wrong uid. 951238032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 951338032Speter called, the code to recover the descriptor was broken. 951438032Speter This sometimes (only sometimes) caused problems with the 951538032Speter alias file. Fix from Motonori Nakamura. 951638032Speter Fix a problem that caused aliaswait to go into infinite recursion 951738032Speter if the @:@ metasymbol wasn't found in the alias file. 951838032Speter Improve error message on newaliases if database files cannot be 951938032Speter opened or if running with no database format defined. 952038032Speter Do a better estimation of the size of error messages when NoReturn 952138032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 952238032Speter Fix a problem causing the "c" option (don't connect to expensive 952338032Speter mailers) to be ignored in SMTP. Problem noted and the 952438032Speter solution suggested by Robert Elz of The University of 952538032Speter Melbourne. 952638032Speter Improve connection caching algorithm by passing "[host]" to 952738032Speter hostsignature, which strips the square brackets and 952838032Speter returns the real name. This allows mailertable entries 952938032Speter to match regular entries. 953038032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 953138032Speter feature, even if it doesn't work right. 953238032Speter Catch and log attempts to try the "wiz" command in server SMTP. 953338032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 953438032Speter Be more generous at assigning $z to the home directory -- do this 953538032Speter for programs that are specified through a .forward file. 953638032Speter Fix from Andrew Chang of Sun Microsystems. 953738032Speter Always save a fatal error message in preference to a non-fatal 953838032Speter error message so that the "subject" line of return 953938032Speter messages is the best possible. 954038032Speter CONFIG: reduce the number of quotes needed to quote configuration 954138032Speter parameters with commas: two quotes should work now, e.g., 954238032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 954338032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 954438032Speter connections (domain-ized UUCP). 954538032Speter CONFIG: fix bug in default maps (-o must be before database file 954664562Sgshapiro name). Pointed out by Christophe Wolfhugel. 954738032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 954838032Speter DNS. This would presumably be used in UUCP islands. 954938032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 955038032Speter CONFIG: log $u in Received: line. This is in technical violation 955138032Speter of the standards, since it doesn't guarantee a domain 955238032Speter on the address. 955338032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 955438032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 955538032Speter the "m" flag should you want it. Apparently some Solaris 2.2 955638032Speter installations can't handle multiple local recipients. 955738032Speter Problem noted by Josh Smith. 955838032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 955938032Speter CONFIG: change default version level from 4 to 5. 956038032Speter CONFIG: add FEATURE(nullclient) to create a config file that 956138032Speter forwards all mail to a hub without ever looking at the 956238032Speter addresses in any detail. 956338032Speter CONFIG: properly strip mailer: information off of relays when 956438032Speter used to change .BITNET form into %-hack form. 956538032Speter CONFIG: fix a problem that caused infinite loops if presented 956638032Speter with an address such as "!foo". 956738032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 956838032Speter the reverse "PTR" mapping is broken. There's a better 956938032Speter way to do this, but the change is fairly major and I 957038032Speter want to hold it for another release. Problem noted by 957138032Speter Bret Marquis. 957238032Speter 957364562Sgshapiro8.5/8.5 1993/07/23 957438032Speter Serious bug: if you used a command line recipient that was unknown 957538032Speter sendmail would not send a return message (it was treating 957638032Speter everything as though it had an SMTP-style client that 957738032Speter would do the return itself). Problem noted by Josh Smith. 957838032Speter Change "trymx" option in getcanonname() to ignore all MX data, 957938032Speter even during a T_ANY query. This actually didn't break 958038032Speter anything, because the only time you called getcanonname 958138032Speter with !trymx was if you already knew there were no MX 958238032Speter records, but it is somewhat cleaner. From Motonori 958338032Speter Nakamura. 958438032Speter Don't call getcanonname from getmxrr if you already know there 958538032Speter are no DNS records matching the name. 958638032Speter Fix a problem causing error messages to always include "The 958738032Speter original message was received ... from localhost". 958838032Speter The correct original host information is now included. 958938032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 959038032Speter version of "test" doesn't have the -x flag). Change it 959138032Speter to use -f instead. From John Myers. 959238032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 959338032Speter esmtp -- it should be smtp. 959438032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 959538032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 959638032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 959738032Speter this cleans up the configs somewhat. This fixes a serious 959838032Speter problem that caused route-addrs to get mistaken as relays, 959938032Speter pointed out by John Myers. WARNING: this also causes 960038032Speter the default on SMART_HOST to change from "suucp" to 960138032Speter "relay" if you have MAILER(smtp) specified. 960238032Speter 960364562Sgshapiro8.4/8.4 1993/07/22 960438032Speter Add option `w'. If you receive a message that comes to you because 960538032Speter you are the best (lowest preference) target of an MX, and 960638032Speter you haven't explicitly recognized the source MX host in 960738032Speter your .cf file, this option will cause you to try the target 960838032Speter host directly (as if there were no MX for it at all). If 960938032Speter `w' is not set, this case is a configuration error. 961038032Speter Beware: if `w' is set, senders may get bogus errors like 961138032Speter "message timed out" or "host unknown" for problems that 961238032Speter are really configuration errors. This option is 961338032Speter disrecommended, provided only for compatibility with 961438032Speter UIUC sendmail. 961538032Speter Fix a problem that caused the incoming socket to be left open 961638032Speter when sendmail forks after the DATA command. This caused 961738032Speter calling systems to wait in FIN_WAIT_2 state until the 961838032Speter entire list was processed and the child closed -- a 961938032Speter potentially prodigious amount of time. Problem noted 962038032Speter by Neil Rickert. 962138032Speter Fix problem (created in 6.64) that caused mail sent to multiple 962238032Speter addresses, one of which was a bad address, to completely 962338032Speter suppress the sending of the message. This changes 962438032Speter handling of EF_FATALERRS somewhat, and adds an 962538032Speter EF_GLOBALERRS flag. This also fixes a potential problem 962638032Speter with duplicate error messages if there is a syntax error 962738032Speter in the header of a message that isn't noticed until late 962838032Speter in processing. Original problem pointed out by Josh Smith 962938032Speter of Harvey Mudd College. This release includes quite a bit 963038032Speter of dickering with error handling (see below). 963138032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 963238032Speter will only hurt already-broken software and should help 963338032Speter humans. 963438032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 963538032Speter compiled in. It would never read the alias file. 963638032Speter Repair unbalanced `)' and `>' (the "open" versions are already 963738032Speter repaired). 963838032Speter Logging of "done" in dropenvelope() was incorrect: it would 963938032Speter log this even when the queue file still existed. Change 964038032Speter this to only log "done" (at log level 11) when the 964138032Speter queue file is actually removed. From John Myers. 964238032Speter Log "lost connection" in server SMTP at log level 20 if there 964338032Speter is no pending transaction. Some senders just close the 964438032Speter connection rather than sending QUIT. 964538032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 964638032Speter domains that do not have MX records -- this would cause 964738032Speter the subsequent host name lookup to fail. The problem 964838032Speter only occurred if you had FEATURE(nocanonify) set. 964938032Speter Problem noted by Rick McCarty of Texas Instruments. 965038032Speter Fix invocation of setvbuf when passed a -X flag -- I had 965138032Speter unwittingly used an ANSI C extension, and this caused 965238032Speter core dumps on some machines. 965338032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 965438032Speter Previously it just gave an empty send queue, which 965538032Speter then gave either "Need RCPT (recipient)" at the DATA 965638032Speter (confusing, since you had given an RCPT command which 965738032Speter returned 250) or just dropped the email, depending on 965838032Speter whether you were running VERBose mode. Now it usually 965938032Speter diagnoses this case as "aliasing/forwarding loop broken". 966038032Speter Unfortunately, it still doesn't adequately diagnose 966138032Speter some true error conditions. 966238032Speter Add internal concept of "warning messages" using 6xx codes. 966338032Speter These are not reported only to Postmaster. Unbalanced 966438032Speter parens, brackets, and quotes are printed as 653 codes. 966538032Speter They are always mapped to 5xx codes before use in SMTP. 966638032Speter Clean up error messages to tell both the actual address that 966738032Speter failed and the alias they arose from. This makes it 966838032Speter somewhat easier to diagnose problems. Difficulty noted 966938032Speter by Motonori Nakamura. 967038032Speter Fix a problem that inappropriately added a ctladdr to addresses 967138032Speter that shouldn't have had one during a queue run. This 967238032Speter caused error messages to be handled differently during 967338032Speter a queue run than a direct run. 967438032Speter Don't print the qf name and line number if you get errors during 967538032Speter the direct run of the queue from srvrsmtp -- this was 967638032Speter just extra stuff for users to crawl through. 967738032Speter Put command line flags on second line of pid file so you can 967838032Speter auto-restart the daemon with all appropriate arguments. 967938032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 968038032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 968138032Speter restart it. 968238032Speter Remove the ``setuid(getuid())'' in main -- this caused the 968338032Speter IDENT daemon to screw up. This required that I change 968438032Speter HASSETEUID to HASSETREUID and complicate the mode 968538032Speter changing somewhat because both Ultrix and SunOS seem 968638032Speter to have a bug causing seteuid() to set the saved uid 968738032Speter as well as the effective. The program test/t_setreuid.c 968838032Speter will test to see if your implementation of setreuid(2) 968938032Speter is appropriately functional. 969038032Speter The FallBackMX (option V) handling failed to properly identify 969138032Speter fallback to yourself -- most of the code was there, 969238032Speter but it wasn't being enabled. Problem noted by Murray 969338032Speter Kucherawy of the University of Waterloo. 969438032Speter Change :include: open timeout from ETIMEDOUT to an internal 969538032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 969638032Speter with CurHostName" in error messages, which can be 969738032Speter confusing. Reported by Jonathan Kamens of OpenVision 969838032Speter Technologies. 969938032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 970038032Speter process group id. The original fix was to get around 970138032Speter some problems with recalcitrant MUAs, but it breaks 970238032Speter any call from a shell that creates a process group id 970338032Speter different from the process id. I could try to fix 970438032Speter this by diddling the tty owner (using tcsetpgrp or 970538032Speter equivalent) but this is too likely to break other 970638032Speter things. 970738032Speter Portability changes: 970838032Speter Support -M as equivalent to -oM on Ultrix -- apparently 970938032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 971038032Speter instead of using standard flags. Oh joy. This 971143730Speter behavior reported by Jon Giltner of University 971238032Speter of Colorado. 971338032Speter SGI IRIX -- this includes several changes that should 971438032Speter help other strict ANSI compilers. 971538032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 971638032Speter Corporation. 971738032Speter Solaris running the Sun C compiler (which despite the 971838032Speter documentation apparently doesn't define 971938032Speter __STDC__ by default). 972038032Speter ConvexOS from Eric Schnoebelen of Convex. 972138032Speter Sony NEWS workstations and Omron LUNA workstations from 972238032Speter Motonori Nakamura. 972338032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 972438032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 972538032Speter several people have made a good argument that this 972638032Speter creates more problems than it solves (although this 972738032Speter may prove painful in the short run). 972838032Speter CONFIG: generalize all the relays to accept a "mailer:host" 972938032Speter format. 973038032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 973138032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 973238032Speter addresses are also passed through this ruleset. 973338032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 973438032Speter internet-style addresses would "fall off the end" of 973538032Speter ruleset zero and be interpreted as local -- however, 973638032Speter the angle brackets confused the recursive call. 973738032Speter These are now diagnosed as "Unrecognized host name". 973838032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 973938032Speter ifdef(`_MAILER_USENET_') instead of 974038032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 974138032Speter of SINTEF RUNIT, Oslo. 974238032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 974338032Speter early in ruleset 0; this allows .mc authors to bypass 974438032Speter things like the "short circuit" code for local addresses. 974538032Speter Prompted by a comment by Bill Wisner of The Well. 974638032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 974738032Speter esmtp) to send SMTP mail. This allows you to default 974838032Speter to esmtp but use a mailertable or other override to 974938032Speter deal with broken servers. This logic was pointed out 975038032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 975138032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 975238032Speter environments. Ugly as sin. 975338032Speter 975464562Sgshapiro8.3/8.3 1993/07/13 975538032Speter Fix setuid problems introduced in 8.2 that caused messages 975638032Speter like "Cannot create qfXXXXXX: Invalid argument" 975738032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 975838032Speter involved a new compile flag "HASSETEUID" that takes 975938032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 976038032Speter that the POSIX interface is broken enough to break 976138032Speter some systems badly. This includes some fixes for 976238032Speter HP-UX. Also fixes problems where the real uid is 976338032Speter not reset properly on startup (from Neil Rickert). 976438032Speter Fix a problem that caused timed out messages to not report the 976538032Speter addresses that timed out. Error messages are also more 976638032Speter "user friendly". 976738032Speter Drop required bandwidth on connections from 64 bytes/sec to 976838032Speter 16 bytes/sec. 976938032Speter Further Solaris portability changes -- doesn't require the BSD 977038032Speter compatibility library. This also adds a new 977138032Speter "HASGETDTABLESIZE" compile flag which can be used if 977238032Speter you want to use getdtablesize(2) instead of sysconf(2). 977338032Speter These are loosely based on changes from David Meyer at 977438032Speter University of Oregon. This now seems to work, at least 977538032Speter for quick test cases. 977638032Speter Fix a problem that can cause duplicate error messages to be 977738032Speter sent if you are in SMTP, you send to multiple addresses, 977838032Speter and at least one of those addresses is good and points 977938032Speter to an account that has a .forward file (whew!). 978038032Speter Fix a problem causing messages to be discarded if checkcompat() 978138032Speter returned EX_TEMPFAIL (because it didn't properly mark 978238032Speter the "to" address). Problem noted by John Myers. 978338032Speter Fix dfopen to return NULL if the open failed; I was depending 978438032Speter on fdopen(-1) returning NULL, which isn't the case. This 978538032Speter isn't serious, but does result in weird error diagnoses. 978638032Speter From Michael Corrigan. 978738032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 978838032Speter messages sent through UUCP-family mailers. Suggested 978938032Speter by Bill Wisner of The Well. 979038032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 979138032Speter include a "uucp-dom" mailer that uses domain-style 979238032Speter addressing. Suggested by Bill Wisner. 979338032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 979438032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 979538032Speter Christophe Wolfhugel. 979638032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 979738032Speter 979864562Sgshapiro8.2/8.2 1993/07/11 979938032Speter Don't drop out on config file parse errors in -bt mode. 980038032Speter On older configuration files, assume option "l" (use Errors-To 980138032Speter header) for back compatibility. NOTE: this DOES NOT 980238032Speter imply an endorsement of the Errors-To: header in any way. 980338032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 980438032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 980538032Speter SMTP server to give an error on this command, and 980638032Speter logging it in the transcript can be confusing. Fix 980738032Speter from Bill Wisner. 980838032Speter IRIX compatibility changes provided by Dan Rich 980938032Speter <drich@sandman.lerc.nasa.gov>. 981038032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 981138032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 981238032Speter <juo@klinzhai.rutgers.edu> 981338032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 981438032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 981538032Speter match the other flags in that file. 981638032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 981738032Speter Save h_errno in mci struct and improve error message display. 981838032Speter Changes from Eric Wassenaar. 981938032Speter Open /dev/null for the transcript if the create of the xf file 982038032Speter failed; this avoids at least one possible null pointer 982138032Speter reference in very weird cases. From Eric Wassenaar. 982238032Speter Clean up statistics gathering; it was over-reporting because of 982338032Speter forks. From Eric Wassenaar. 982438032Speter Fix problem that causes old Return-Path: line to override new 982538032Speter Return-Path: line (conf.c needs H_FORCE to avoid 982638032Speter re-using old value). From Motonori Nakamura. 982738032Speter Fix broken -m flag in K definition -- even if -m (match only) 982838032Speter was specified, it would still replace the key with the 982938032Speter value. Noted by Rick McCarty of Texas Instruments. 983038032Speter If the name server timed out over several days, no "timed out" 983138032Speter message would ever be sent back. The timeout code 983238032Speter has been moved from markfailure() to dropenvelope() 983338032Speter so that all such failures should be diagnosed. Pointed 983438032Speter out by Christophe Wolfhugel and others. 983538032Speter Relax safefile() constraints: directories in an include or 983638032Speter forward path must be readable by self if the controlling 983738032Speter user owns the entry, readable by all otherwise (e.g., 983838032Speter when reading your .forward file, you have to own and 983938032Speter have X permission in it; everyone needs X permission in 984038032Speter the root and directories leading up to your home); 984138032Speter include files must be readable by anyone, but need not 984238032Speter be owned by you. 984338032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 984438032Speter reading a .forward file; this gets around some problems 984538032Speter on NFS mounts if root permission is not exported and 984638032Speter the user's home directory isn't x'able. 984738032Speter Additional NeXT portability enhancements from Axel Zinser. 984838032Speter Additional HP-UX portability enhancements from Brian Bullen. 984938032Speter Add a timeout around SMTP message writes; this assumes you can 985038032Speter get throughput of at least 64 bytes/second. Note that 985138032Speter this does not impact the "datafinal" default, which 985238032Speter is separate; this is just intended to work around 985338032Speter network clogs that will occur before the final dot 985438032Speter is sent. From Eric Wassenaar. 985538032Speter Change map code to set the "include null" flag adaptively -- 985638032Speter it initially tries both, but if it finds anything 985738032Speter matching without a null it never tries again with a 985838032Speter null and vice versa. If -N is specified, it never 985938032Speter tries without the null and creates new maps with a 986038032Speter null byte. If -O is specified, it never tries with 986138032Speter the null (for efficiency). If -N and -O are specified, 986238032Speter you get -NO (get it?) lookup at all, so this would 986338032Speter be a bad idea. If you don't specify either -N or -O, 986438032Speter it adapts. 986538032Speter Fix recognition of "same from address" so that MH submissions 986638032Speter will insert the appropriate full name information; 986738032Speter this used to work and got broken somewhere along the 986838032Speter way. 986938032Speter Some changes to eliminate some unnecessary SYSERRs in the 987038032Speter log. For example, if you lost a connection, don't 987138032Speter bother reporting that fact on the connection you lost. 987238032Speter Add some "extended debugging" flags to try to track down 987338032Speter why we get occasional problems with file descriptor 987438032Speter one being closed when execing a mailer; it seems to 987538032Speter only happen when there has been another error in the 987638032Speter same transaction. This requires XDEBUG, defined 987738032Speter by default in conf.h. 987838032Speter Add "-X filename" command line flag, which logs both sides of 987938032Speter all SMTP transactions. This is intended ONLY for 988038032Speter debugging bad implementations of other mailers; start 988138032Speter it up, send a message from a mailer that is failing, 988238032Speter and then kill it off and examine the indicated log. 988338032Speter This output is not intended to be particularly human 988438032Speter readable. This also adds the HASSETVBUF compile 988538032Speter flag, defaulted on if your compiler defines __STDC__. 988638032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 988738032Speter have a local net that should get direct connects, you 988838032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 988938032Speter See cf/README for an example. 989038032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 989138032Speter sites that don't use the -d flag. 989238032Speter CONFIG: hide recipient addresses as well as sender addresses 989338032Speter behind $M if FEATURE(allmasquerade) is specified; this 989438032Speter has been requested by several people, but can break 989538032Speter local aliases. For example, if you mail to "localalias" 989638032Speter this will be rewritten as "localalias@masqueradehost"; 989738032Speter although initial delivery will work, replies will be 989838032Speter broken. Use it sparingly. 989938032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 990038032Speter to qualified domains in headers. I believe this is 990138032Speter largely equivalent to the IDA feature of the same name. 990238032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 990338032Speter to override the "system name" as your UUCP name -- 990438032Speter in particular, to use domain-ized UUCP names. From 990538032Speter Bill Wisner of The Well. 990638032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 990738032Speter first. This is currently unused in the config files, 990838032Speter but could be used in a mailertable entry. 990938032Speter 991064562Sgshapiro8.1C/8.1B 1993/06/27 991138032Speter Serious security bug fix: it was possible to read any file on 991238032Speter the system, regardless of ownership and permissions. 991338032Speter If a subroutine returns a fully qualified address, return it 991438032Speter immediately instead of feeding it back into rewriting. 991538032Speter This fixes a problem with mailertable lookups. 991638032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 991738032Speter 991864562Sgshapiro8.1B/8.1A 1993/06/12 991938032Speter Serious bug fix: pattern matching backup algorithm stepped by 992038032Speter two tokens in classes instead of one. Found by Claus 992138032Speter Assmann at University of Kiel, Germany. 992238032Speter 992364562Sgshapiro8.1A/8.1A 1993/06/08 992438032Speter Another mailertable fix.... 992538032Speter 992664562Sgshapiro8.1/8.1 1993/06/07 992738032Speter 4.4BSD freeze.
