138032Speter SENDMAIL RELEASE NOTES 2159609Sgshapiro $Id: RELEASE_NOTES,v 8.1777.2.6 2006/06/05 22:32:41 ca Exp $ 338032Speter 438032Speter 538032SpeterThis listing shows the version of the sendmail binary, the version 638032Speterof the sendmail configuration files, the date of release, and a 738032Spetersummary of the changes in that release. 838032Speter 9159609Sgshapiro8.13.7/8.13.7 2006/06/14 10159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 11159609Sgshapiro crash while trying to send a mail due to a stack overflow, 12159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 13159609Sgshapiro happens because the recursion of the function mime8to7() 14159609Sgshapiro was not restricted. The function is called for MIME 8 to 15159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 16159609Sgshapiro To work around this problem, recursive calls are limited to 17159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 18159609Sgshapiro limit is treated as opaque and is not checked further. 19159609Sgshapiro Problem noted by Frank Sheiness. 20159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 21159609Sgshapiro SASL mechanisms that use the security layer, e.g., 22159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 23159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 24159609Sgshapiro a df file might have been left behind in the queue. 25159609Sgshapiro This was another side effect of the changes to the I/O 26159609Sgshapiro layer made in 8.13.6. 27159609Sgshapiro Several minor problems have been fixed that were found by a 28159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 29159609Sgshapiro distribution. See http://scan.coverity.com/ 30159609Sgshapiro Note: the scan generated also a lot of "false positives", 31159609Sgshapiro e.g., "error" reports about situations that cannot happen. 32159609Sgshapiro Most of those code places are marked with lint(1) comments 33159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 34159609Sgshapiro Hence an explicit assertion has been added in some cases 35159609Sgshapiro to avoid those false positives. 36159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 37159609Sgshapiro error then in some cases shared memory segments or pid 38159609Sgshapiro files were not removed. 39159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 40159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 41159609Sgshapiro reported by Akihiro Sagawa. 42159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 43159609Sgshapiro bug work-around. Hence if sendmail is linked against 44159609Sgshapiro either of these versions and compression is available, 45159609Sgshapiro the padding bug work-around is turned off. Based on 46159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 47159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 48159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 49159609Sgshapiro however, that list is no longer available. To avoid 50159609Sgshapiro further problems, no default value is available anymore, 51159609Sgshapiro but an argument must be specified. 52159609Sgshapiro Portability: 53159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c. Patch from 54159609Sgshapiro Pieter Bowman of the University of Utah. 55159609Sgshapiro 56157001Sgshapiro8.13.6/8.13.6 2006/03/22 57157001Sgshapiro SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server 58157001Sgshapiro and client side of sendmail with timeouts in the libsm I/O 59157001Sgshapiro layer and fix problems in that code. Also fix handling of 60157001Sgshapiro a buffer in sm_syslog() which could have been used as an 61157001Sgshapiro attack vector to exploit the unsafe handling of 62157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 63157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 64157001Sgshapiro Handle theoretical integer overflows that could triggered if 65157001Sgshapiro the server accepted headers larger than the maximum 66157001Sgshapiro (signed) integer value. This is prevented in the default 67157001Sgshapiro configuration by restricting the size of a header, and on 68157001Sgshapiro most machines memory allocations would fail before reaching 69157001Sgshapiro those values. Problems found by Phil Brass of ISS. 70157001Sgshapiro If a server returns 421 for an RSET command when trying to start 71157001Sgshapiro another transaction in a session while sending mail, do 72157001Sgshapiro not trigger an internal consistency check. Problem found 73157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 74157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 75157001Sgshapiro to a STARTTLS command despite the fact that it advertised 76157001Sgshapiro STARTTLS and that the code is not valid according to RFC 77157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 78157001Sgshapiro of a protocol error (which has been changed to a 79157001Sgshapiro temporary error in 8.13.5). Problem reported by Jeff 80157001Sgshapiro A. Earickson of Colby College. 81157001Sgshapiro Clear SMTP state after a HELO/EHLO command. Patch from John 82157001Sgshapiro Myers of Proofpoint. 83157001Sgshapiro Observe MinQueueAge option when gathering entries from the queue 84157001Sgshapiro for sorting etc instead of waiting until the entries are 85157001Sgshapiro processed. Patch from Brian Fundakowski Feldman. 86157001Sgshapiro Set up TLS session cache to properly handle clients that try to 87157001Sgshapiro resume a stored TLS session. 88157001Sgshapiro Properly count the number of (direct) child processes such that 89157001Sgshapiro a configured value (MaxDaemonChildren) is not exceeded. 90157001Sgshapiro Based on patch from Attila Bruncsak. 91157001Sgshapiro LIBMILTER: Remove superfluous backslash in macro definition 92157001Sgshapiro (libmilter.h). Based on patch from Mike Kupfer of 93157001Sgshapiro Sun Microsystems. 94157001Sgshapiro LIBMILTER: Don't try to set SO_REUSEADDR on UNIX domain sockets. 95157001Sgshapiro This generates an error message from libmilter on 96157001Sgshapiro Solaris, though other systems appear to just discard the 97157001Sgshapiro request silently. 98157001Sgshapiro LIBMILTER: Deal with sigwait(2) implementations that return 99157001Sgshapiro -1 and set errno instead of returning an error code 100157001Sgshapiro directly. Patch from Chris Adams of HiWAAY Informations 101157001Sgshapiro Services. 102157001Sgshapiro Portability: 103157001Sgshapiro Fix compilation checks for closefrom(3) and statvfs(2) 104157001Sgshapiro in NetBSD. Problem noted by S. Moonesamy, patch from 105157001Sgshapiro Andrew Brown. 106157001Sgshapiro 107157001Sgshapiro8.13.5/8.13.5 2005/09/16 108157001Sgshapiro Store the filesystem identifier of the df/ subdirectory (if it 109157001Sgshapiro exists) in an internal structure instead of the base 110157001Sgshapiro directory. This structure is used decide whether there 111157001Sgshapiro is enough free disk space when selecting a queue, hence 112157001Sgshapiro without this change queue selection could fail if a df/ 113157001Sgshapiro subdirectory exists and is on a different filesystem 114157001Sgshapiro than the base directory. 115157001Sgshapiro Use the queue index of the df file (instead of the qf file) for 116157001Sgshapiro checking whether a link(2) operation can be used to split 117157001Sgshapiro an envelope across queue groups. Problem found by 118157001Sgshapiro Werner Wiethege. 119157001Sgshapiro If the list of items in the queue is larger than the maximum 120157001Sgshapiro number of items to process, sort the queue first and 121157001Sgshapiro then cut the list off instead of the other way around. 122157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 123157001Sgshapiro Fix helpfile to show full entry for ETRN. Problem noted by 124157001Sgshapiro Penelope Fudd, patch from Neil Rickert of Northern Illinois 125157001Sgshapiro University. 126157001Sgshapiro FallbackSmartHost should also be tried on temporary errors. 127157001Sgshapiro From John Beck of Sun Microsystems. 128157001Sgshapiro When a server responds with 421 to the STARTTLS command then treat 129157001Sgshapiro it as a temporary error, not as protocol error. Problem 130157001Sgshapiro noted by Andrey J. Melnikoff. 131157001Sgshapiro Properly define two functions in libsm as static because their 132157001Sgshapiro prototype used static too. Patch from Peter Klein. 133157001Sgshapiro Fix syntax errors in helpfile for MAIL and RCPT commands. 134157001Sgshapiro LIBMILTER: When smfi_replacebody() is called with bodylen equals 135157001Sgshapiro zero then do not silently ignore that call. Patch from 136157001Sgshapiro Gurusamy Sarathy of Active State. 137157001Sgshapiro LIBMILTER: Recognize "421" also in a multi-line reply to terminate 138157001Sgshapiro the SMTP session with that error. Fix from Brian Kantor. 139157001Sgshapiro Portability: New option HASSNPRINTF which can be set if the OS 140157001Sgshapiro has a properly working snprintf(3) to get rid 141157001Sgshapiro of the last two (safe) sprintf(3) calls in the 142157001Sgshapiro source code. 143157001Sgshapiro Add support for AIX 5.3. 144157001Sgshapiro Add support for SunOS 5.11 (aka Solaris 11). 145157001Sgshapiro Add support for Darwin 8.x. Patch from Lyndon Nerenberg. 146157001Sgshapiro OpenBSD 3.7 has removed support for NETISO. 147157001Sgshapiro CONFIG: Add OSTYPE(freebsd6) for FreeBSD 6.X. 148157001Sgshapiro Set DontBlameSendmail to AssumeSafeChown and 149157001Sgshapiro GroupWritableDirPathSafe for OSTYPE(darwin). 150157001Sgshapiro Patch from Lyndon Nerenberg. 151157001Sgshapiro Some features still used 4.7.1 as enhanced status code which 152157001Sgshapiro was supposed to be eliminated in 8.13.0 because some 153157001Sgshapiro broken systems misinterpret it as a permanent error. 154157001Sgshapiro Patch from Matej Vela of Rudjer Boskovic Institute. 155157001Sgshapiro Some default values in a generated cf file did not match 156157001Sgshapiro the defaults in the sendmail binary. Problem noted 157157001Sgshapiro by Mike Pechkin. 158157001Sgshapiro New Files: 159157001Sgshapiro cf/ostype/freebsd6.m4 160157001Sgshapiro devtools/OS/AIX.5.3 161157001Sgshapiro devtools/OS/Darwin.8.x 162157001Sgshapiro devtools/OS/SunOS.5.11 163157001Sgshapiro include/sm/time.h 164157001Sgshapiro 165147078Sgshapiro8.13.4/8.13.4 2005/03/27 166147078Sgshapiro The bug fixes in 8.13.3 for connection handling uncovered a 167147078Sgshapiro different error which could result in connections that 168147078Sgshapiro stay in CLOSE_WAIT state due to a variable that was not 169147078Sgshapiro properly initialized. Problem noted by Michael Sims. 170147078Sgshapiro Deal with empty hostnames in hostsignature(). This bug could lead 171147078Sgshapiro to an endless loop when doing LMTP deliveries to another 172147078Sgshapiro host. Problem first reported by Martin Lathoud and 173147078Sgshapiro tracked down by Gael Roualland. 174147078Sgshapiro Make sure return parameters are initialized in getmxrr(). Problem 175147078Sgshapiro found by Gael Roualland using valgrind. 176147078Sgshapiro If shared memory is used and the RunAsUser option is set, then the 177147078Sgshapiro owner and group of the shared memory segment is set to 178147078Sgshapiro the ids specified RunAsUser and the access mode is set 179147078Sgshapiro to 0660 to allow for updates by sendmail processes. 180147078Sgshapiro The number of queue entries that is (optionally) kept in shared 181147078Sgshapiro memory was wrong in some cases, e.g., envelope splitting 182147078Sgshapiro and bounce generation. 183147078Sgshapiro Undo a change made in 8.13.0 to silently truncate long strings 184147078Sgshapiro in address rewriting because the message can be triggered 185147078Sgshapiro for header checks where long strings are legitimate. 186147078Sgshapiro Problem reported by Mary Verge DeSisto, and tracked 187147078Sgshapiro down with the help of John Beck of Sun Microsystems. 188147078Sgshapiro The internal stab map did not obey the -m flag. Patch from 189147078Sgshapiro Rob McMahon of Warwick University, England. 190147078Sgshapiro The socket map did not obey the -f flag. Problem noted by 191147078Sgshapiro Dan Ringdahl, forwarded by Andrzej Filip. 192147078Sgshapiro The addition of LDAP recursion in 8.13.0 broke enforcement of 193147078Sgshapiro the LDAP map -1 argument which tells the MTA to only 194147078Sgshapiro return success if and only if a single LDAP match is found. 195147078Sgshapiro Add additional error checks in the MTA for milter communication 196147078Sgshapiro to avoid a possible segmentation fault. Based on patch 197147078Sgshapiro by Joe Maimon. 198147078Sgshapiro Do not trigger an assertion if X509_digest() returns success but 199147078Sgshapiro does not assign a value to its output parameter. Based 200147078Sgshapiro on patch by Brian Kantor. 201147078Sgshapiro Add more checks when resetting internal AUTH data (applies only 202147078Sgshapiro to Cyrus SASL version 2). Otherwise an SMTP session might 203147078Sgshapiro be dropped after an AUTH failure. 204147078Sgshapiro Portability: 205147078Sgshapiro Add LA_LONGLONG as valid LA_TYPE type for systems that use 206147078Sgshapiro "long long" to read load average data, e.g., 207147078Sgshapiro AIX 5.1 in 32 bit mode. Note: this has to be set 208147078Sgshapiro "by hand", it is not (yet) automatically detected. 209147078Sgshapiro Problem noted by Burak Bilen. 210147078Sgshapiro Use socklen_t for accept(), etc. on AIX 5.x. This should 211147078Sgshapiro fix problems when compiling in 64 bit mode. 212147078Sgshapiro Problem first reported by Harry Meiert of 213147078Sgshapiro University of Bremen. 214147078Sgshapiro New Files: 215147078Sgshapiro include/sm/sem.h 216147078Sgshapiro libsm/sem.c 217147078Sgshapiro libsm/t-sem.c 218147078Sgshapiro 219141858Sgshapiro8.13.3/8.13.3 2005/01/11 220141858Sgshapiro Enhance handling of I/O errors, especially EOF, when STARTTLS 221141858Sgshapiro is active. 222141858Sgshapiro Make sure a connection is not reused after it has been closed 223141858Sgshapiro due to a 421 error. Problem found by Allan E Johannesen 224141858Sgshapiro of Worcester Polytechnic Institute. 225141858Sgshapiro Avoid triggering an assertion when sendmail is interrupted while 226141858Sgshapiro closing a connection. Problem found by Allan E Johannesen 227141858Sgshapiro of Worcester Polytechnic Institute. 228141858Sgshapiro Regression: a change in 8.13.2 caused sendmail not to try the 229141858Sgshapiro next MX host (or FallbackMXhost if configured) when, at 230141858Sgshapiro connection open, the current server returns a 4xy or 5xy 231141858Sgshapiro SMTP reply code. Problem noted by Mark Tranchant. 232141858Sgshapiro 233141858Sgshapiro8.13.2/8.13.2 2004/12/15 234141858Sgshapiro Do not split the first header even if it exceeds the internal 235141858Sgshapiro buffer size. Previously a part of such a header would 236141858Sgshapiro end up in the body of the message. Problem noted by 237141858Sgshapiro Simple Nomad of BindView. 238141858Sgshapiro Do not complain about "cataddr: string too long" when checking 239141858Sgshapiro headers that do not contain RFC 2822 addresses. 240141858Sgshapiro Problem noted by Rich Graves of Brandeis University. 241141858Sgshapiro If a server returns a 421 reply to the RSET command between 242141858Sgshapiro message deliveries, do not attempt to deliver any more 243141858Sgshapiro messages on that connection. This prevents bogus "Bad 244141858Sgshapiro file number" recipient status. Problem noted by 245141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 246141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 247141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 248141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 249141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 250141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 251141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 252141858Sgshapiro them off at a comma. Problem noted by Krzysztof Oledzki. 253141858Sgshapiro Add more logging to milter change header functions to 254141858Sgshapiro complement existing logging. Based on patch from 255141858Sgshapiro Gurusamy Sarathy of Active State. 256141858Sgshapiro Include <lber.h> in include/sm/config.h when LDAPMAP is defined. 257141858Sgshapiro Patch from Edgar Hoch of the University of Stuttgart. 258141858Sgshapiro Fix DNS lookup if IPv6 is enabled when converting an IP address 259141858Sgshapiro to a hostname for use with SASL. Problem noted by Ken Jones; 260141858Sgshapiro patch from Hajimu UMEMOTO. 261141858Sgshapiro CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog 262141858Sgshapiro mailer. Patch from John Beck of Sun Microsystems. 263141858Sgshapiro LIBMILTER: It was possible that xxfi_abort() was called after 264141858Sgshapiro xxfi_eom() for a message if some timeouts were triggered. 265141858Sgshapiro Patch from Alexey Kravchuk. 266141858Sgshapiro LIBMILTER: Slightly rearrange mutex use in listener.c to allow 267141858Sgshapiro different threads to call smfi_opensocket() and smfi_main(). 268141858Sgshapiro Patch from Jordan Ritter of Cloudmark. 269141858Sgshapiro MAIL.LOCAL: Properly terminate MBDB before exiting. Problem 270141858Sgshapiro noted by Nelson Fung. 271141858Sgshapiro MAIL.LOCAL: make strip-mail.local used a wrong path to access 272141858Sgshapiro mail.local. Problem noted by William Park. 273141858Sgshapiro VACATION: Properly terminate MBDB before exiting. Problem noted 274141858Sgshapiro by Nelson Fung. 275141858Sgshapiro Portability: 276141858Sgshapiro Add support for DragonFly BSD. 277141858Sgshapiro New Files: 278141858Sgshapiro cf/ostype/dragonfly.m4 279141858Sgshapiro devtools/OS/DragonFly 280141858Sgshapiro include/sm/os/sm_os_dragonfly.h 281141858Sgshapiro Deleted Files: 282141858Sgshapiro libsm/vsscanf.c 283141858Sgshapiro 284132943Sgshapiro8.13.1/8.13.1 2004/07/30 285132943Sgshapiro Using the default AliasFile ldap: specification would cause the 286132943Sgshapiro objectClasses of the LDAP response to be included in the 287132943Sgshapiro alias expansion. Problem noted by Brenden Conte of 288132943Sgshapiro Rensselaer Polytechnic Institute. 289132943Sgshapiro Fix support for a fallback smart host for system where DNS is 290132943Sgshapiro (partially) available. From John Beck of Sun Microsystems. 291132943Sgshapiro Fix SuperSafe=PostMilter behavior when a milter replaces a body 292132943Sgshapiro but the data file is not yet stored on disk because it is 293132943Sgshapiro smaller than the size of the memory buffer. Problem noted 294132943Sgshapiro by David Russell. 295132943Sgshapiro Fix certificate revocation list support; if a CRL was specified 296132943Sgshapiro but the other side presented a cert that was signed by 297132943Sgshapiro a different (trusted) CA than the one which issued the CRL, 298132943Sgshapiro verification would always fail. Problem noted by Al Smith. 299132943Sgshapiro Run mailer programs as the RunAsUser when RunAsUser is set and 300132943Sgshapiro the F=S mailer flag is set without a U= mailer equate. 301132943Sgshapiro Problem noted by John Gardiner Myers of Proofpoint. 302132943Sgshapiro ${nbadrcpts} was off by one if BadRcptThrottle is zero. 303132943Sgshapiro Patch from Sung-hoon Choi of DreamWiz Inc. 304132943Sgshapiro CONFIG: Emit a warning if FEATURE(`access_db') is used after 305132943Sgshapiro FEATURE(`greet_pause') because then the latter will not 306132943Sgshapiro use the access map. Note: if no default value is given 307132943Sgshapiro for FEATURE(`greet_pause') then it issues an error if 308132943Sgshapiro FEATURE(`access_db') is not specified before it. 309132943Sgshapiro Problem noted by Alexander Dalloz of University of 310132943Sgshapiro Bielefeld. 311132943Sgshapiro CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause') 312132943Sgshapiro is used to give more flexibility for local changes. 313132943Sgshapiro Portability: 314132943Sgshapiro Fix a 64 bit problem in the socket map code. Problem 315132943Sgshapiro noted by Geoff Adams. 316132943Sgshapiro NetBSD 2.0F has closefrom(3). Patch from Andrew Brown. 317132943Sgshapiro NetBSD can use sysctl(3) to get the number of CPUs in 318132943Sgshapiro a system. Patch from Andrew Brown. 319132943Sgshapiro Add a README file in doc/op/ to explain potential 320132943Sgshapiro incompatibilities with various *roff related 321132943Sgshapiro tools. Problem tracked down by Per Hedeland. 322132943Sgshapiro New Files: 323132943Sgshapiro doc/op/README 324132943Sgshapiro 325132943Sgshapiro8.13.0/8.13.0 2004/06/20 326132943Sgshapiro Do not include AUTH data in a bounce to avoid leaking confidential 327132943Sgshapiro information. See also cf/README about MSP and the section 328132943Sgshapiro "Providing SMTP AUTH Data when sendmail acts as Client". 329132943Sgshapiro Problem noted by Neil Rickert of Northern Illinois 330132943Sgshapiro University. 331132943Sgshapiro Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n 332132943Sgshapiro and -DSM_CONF_SETITIMER=0. Problem noted by Juergen Georgi 333132943Sgshapiro of RUS University of Stuttgart. 334132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 335132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 336132943Sgshapiro Add support for LDAP recursion based on types given to attribute 337132943Sgshapiro specifications in an LDAP map definition. This allows 338132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 339132943Sgshapiro URL which will in turn be queried. See the ``LDAP 340132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 341132943Sgshapiro Based on patch from Andrew Baucom. 342132943Sgshapiro Extend the default LDAP specifications for AliasFile 343132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 344132943Sgshapiro include support for LDAP recursion via new attributes. 345132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 346132943Sgshapiro of cf/README for more information. 347132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 348132943Sgshapiro LDAP API/protocol version to use. The default depends on 349132943Sgshapiro the LDAP library. 350132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 351132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 352132943Sgshapiro and -p port. This also allows for the use of LDAP over 353132943Sgshapiro SSL and connections via named sockets if your LDAP 354132943Sgshapiro library supports it. 355132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 356132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 357132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 358132943Sgshapiro during a SMTP session then terminate it just like it is 359132943Sgshapiro done for too many bad SMTP commands. 360132943Sgshapiro Basic connection rate control support has been added: the daemon 361132943Sgshapiro maintains the number of incoming connections per client 362132943Sgshapiro IP address and total in the macros {client_rate} and 363132943Sgshapiro {total_rate}, respectively. These macros can be used 364132943Sgshapiro in the cf file to impose connection rate limits. 365132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 366132943Sgshapiro determines the length of the interval for which the 367132943Sgshapiro number of connections is stored. Based on patch from 368132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 369132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 370132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 371132943Sgshapiro If enabled by the new ruleset greet_pause (see 372132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 373132943Sgshapiro amount of time before sending the initial 220 SMTP 374132943Sgshapiro greeting. If any traffic is received before then, a 554 375132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 376132943Sgshapiro during that connection. 377132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 378132943Sgshapiro server could sleep for a very long time. Fix based on 379132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 380132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 381132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 382132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 383132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 384132943Sgshapiro misinterpret it as a permanent error. 385132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 386132943Sgshapiro all milters accepted the mail. This can increase 387132943Sgshapiro performance if many mails are rejected by milters due to 388132943Sgshapiro body scans. Based on patch from David F. Skoll. 389132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 390132943Sgshapiro header, whether provided by the client or generated by 391132943Sgshapiro sendmail. 392132943Sgshapiro New macro {client_connections} which contains the number of open 393132943Sgshapiro connections in the SMTP server for the client IP address. 394132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 395132943Sgshapiro Mines de Paris. 396132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 397132943Sgshapiro to prevent confusion caused by running sendmail stop 398132943Sgshapiro scripts two or more times, where the second and subsequent 399141858Sgshapiro runs would report misleading error messages about sendmail's 400132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 401132943Sgshapiro for a discussion of the implications of this, including 402132943Sgshapiro how to correct broken scripts which may have depended on 403132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 404132943Sgshapiro Support per-daemon input filter lists which override the default 405132943Sgshapiro filter list specified in InputMailFilters. The filters 406132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 407132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 408132943Sgshapiro your configuration relies on this behavior, you have to 409132943Sgshapiro add those names to class 'w' yourself. Problem noted 410132943Sgshapiro by Sander Eerkes. 411132943Sgshapiro Support message quarantining in the mail queue. Quarantined 412132943Sgshapiro messages are not run on normal queue displays or runs 413132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 414132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 415132943Sgshapiro The -q command line option now can specify which queue to display 416132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 417132943Sgshapiro operates on lost queue items. 418132943Sgshapiro Restricted mail queue runs and displays can be done based on the 419132943Sgshapiro quarantined reason using -qQtext to run or display 420132943Sgshapiro quarantined items if the quarantine reason contains the 421132943Sgshapiro given text. Similarly, -q!Qtext will run or display 422132943Sgshapiro quarantined items which do not have the given text in the 423132943Sgshapiro quarantine reason. 424132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 425132943Sgshapiro new -Q option. See doc/op/op.me for more information. 426132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 427132943Sgshapiro quarantine reason is shown in a new line prefixed by 428132943Sgshapiro "QUARANTINE:". 429132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 430132943Sgshapiro to quarantine messages in check_* (except check_compat) and 431132943Sgshapiro header check rulesets. The $: of the mailer triplet will 432132943Sgshapiro be used for the quarantine reason. 433132943Sgshapiro Add a new quarantine count to the mailstats collected. 434132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 435132943Sgshapiro message if it is quarantined. 436132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 437132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 438132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 439132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 440132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 441132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 442132943Sgshapiro lookup for the client IP address. Note: this is the same 443132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 444132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 445132943Sgshapiro recipients received so far in a transaction. 446132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 447132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 448132943Sgshapiro noted by Kai Schlichting. 449132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 450132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 451132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 452132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 453132943Sgshapiro Wolfhugel of France Telecom Oleane. 454132943Sgshapiro Do not silently truncate long strings in address rewriting. 455132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 456132943Sgshapiro Oceana Matrix Ltd. 457132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 458132943Sgshapiro support mutual authentication. From Kenneth Murchison of 459132943Sgshapiro Oceana Matrix Ltd. 460132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 461132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 462132943Sgshapiro format just like the STARTTLS related macros to avoid 463132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 464132943Sgshapiro Masarati of SysNet s.n.c. 465132943Sgshapiro New option AuthRealm to set the authentication realm that is 466132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 467132943Sgshapiro of the University of Manitoba. 468132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 469132943Sgshapiro successful, otherwise relaying would be allowed if 470132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 471132943Sgshapiro is active. 472132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 473132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 474132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 475132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 476132943Sgshapiro DIGEST-MD5 and LOGIN. 477132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 478132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 479132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 480132943Sgshapiro overwrite each other's pid files. 481132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 482132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 483132943Sgshapiro Wolfhugel of France Telecom. 484132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 485132943Sgshapiro LogLevel 12 or higher. 486132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 487132943Sgshapiro try to use the SMTP command VERB to propagate this option 488132943Sgshapiro to the MTA which in turn will show the delivery just like 489132943Sgshapiro it was done before the default 8.12 separation of MSP and 490132943Sgshapiro MTA. Based on patch by Per Hedeland. 491132943Sgshapiro If a daemon is refusing connections for longer than the time specified 492132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 493132943Sgshapiro to high load, log this information. Patch from John Beck 494132943Sgshapiro of Sun Microsystems. 495132943Sgshapiro Remove the ability for non-trusted users to raise the value of 496132943Sgshapiro CheckpointInterval on the command line. 497132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 498132943Sgshapiro subset of the functionality of the 's' flag. 499132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 500132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 501132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 502132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 503132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 504132943Sgshapiro causing subsequent messages to be sent instead of being 505132943Sgshapiro discarded. This also caused milter callbacks to be called 506132943Sgshapiro out of order after the SMTP session was reset. 507132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 508132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 509132943Sgshapiro further information. 510132943Sgshapiro New command line option -D logfile to send debug output to 511132943Sgshapiro the indicated log file instead of stdout. 512132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 513132943Sgshapiro queue return and warning times for delivery status 514132943Sgshapiro notifications. 515132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 516132943Sgshapiro at all. 517132943Sgshapiro Several more return values for ruleset srv_features have been added 518132943Sgshapiro to enable/disable certain features in the server per 519132943Sgshapiro connection. See doc/op/op.me for details. 520132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 521132943Sgshapiro for DaemonPortOptions. 522132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 523132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 524132943Sgshapiro of Northern Illinois University. 525132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 526132943Sgshapiro be tried as a last resort after all other fallbacks. This 527132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 528132943Sgshapiro view of inside the company, but an incomplete view of 529132943Sgshapiro outside). From John Beck of Sun Microsystems. 530132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 531132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 532132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 533132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 534132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 535132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 536132943Sgshapiro of the University of Illinois at Urbana-Champaign. 537132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 538132943Sgshapiro applications for use in the xxfi_eom() callback. 539132943Sgshapiro New macro {time} which contains the output of the time(3) function, 540132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 541132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 542132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 543132943Sgshapiro terminate the SMTP session with a 421 error message. 544132943Sgshapiro Get rid of dead code that tried to access the environment variable 545132943Sgshapiro HOSTALIASES. 546132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 547132943Sgshapiro compile with -DUSE_TTYPATH=1. 548132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 549132943Sgshapiro the header value passed in without balancing quotes, 550132943Sgshapiro parentheses, and angle brackets. Based on patch from 551132943Sgshapiro Oleg Bulyzhin. 552132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 553132943Sgshapiro angle brackets when reading in rulesets. This allows 554132943Sgshapiro rules to be written for header checks to catch strings 555132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 556132943Sgshapiro Based on patch from Oleg Bulyzhin. 557132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 558132943Sgshapiro some temporary errors like ECONNABORTED. 559132943Sgshapiro Added list of CA certificates that are used by members of the 560132943Sgshapiro sendmail consortium, see CACerts. 561132943Sgshapiro Portability: 562132943Sgshapiro Two new compile options have been added: 563132943Sgshapiro HASCLOSEFROM System has closefrom(3). 564132943Sgshapiro HASFDWALK System has fdwalk(3). 565132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 566132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 567132943Sgshapiro change to using fcntl() locking until they can fix 568132943Sgshapiro it. Be sure to update other sendmail related 569132943Sgshapiro programs to match locking techniques. 570132943Sgshapiro New compile time option NEEDINTERRNO which should be set 571132943Sgshapiro if <errno.h> does not declare errno itself. 572132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 573132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 574132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 575132943Sgshapiro Center for Scientific Computing. 576132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 577132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 578132943Sgshapiro Remove path from compiler definition for Interix because 579132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 580132943Sgshapiro Also use <sys/mkdev.h> to get the correct 581132943Sgshapiro major()/minor() definitions. Based on feedback 582132943Sgshapiro from Mark Funkenhauser. 583132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 584132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 585132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 586132943Sgshapiro cf/sendmail.schema for more information. 587132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 588132943Sgshapiro is of the form "user:group" when used for submit.mc. 589132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 590132943Sgshapiro of Northern Illinois University. 591132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 592132943Sgshapiro instructs the check_* (except check_compat) to quarantine 593132943Sgshapiro the message using the given reason. 594132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 595132943Sgshapiro instead of "host" to avoid problem with looking up other 596132943Sgshapiro DNS records than just A. 597132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 598132943Sgshapiro length of the interval for which the number of incoming 599132943Sgshapiro connections is maintained. 600132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 601132943Sgshapiro rate control for individual hosts or nets. 602132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 603132943Sgshapiro number of open SMTP connections for individual hosts or nets. 604132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 605132943Sgshapiro slamming protection described above. The feature can 606132943Sgshapiro take an argument specifying the milliseconds to wait and/or 607132943Sgshapiro use the access database to look the pause time based on 608132943Sgshapiro client hostname, domain, IP address, or subnet. 609132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 610132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 611132943Sgshapiro rejections based on the unverified hostname of client, 612132943Sgshapiro which turns on the same behavior as in earlier sendmail 613132943Sgshapiro versions when delay_checks was not in use.

Cannot resolve PTR 1101102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1102102528Sgshapiro modification causes a change of behavior if an IP net/address 1103102528Sgshapiro is listed in the access map with REJECT and a host/domain 1104102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1105102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1106102528Sgshapiro change was made on request of Neil Rickert of Northern 1107102528Sgshapiro Illinois University, the side effect has been found by 1108102528Sgshapiro Stefaan Van Hoornick. 1109102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1110102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1111102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1112102528Sgshapiro University. 1113102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1114102528Sgshapiro Fix from Andrzej Filip. 1115102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1116102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1117102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1118102528Sgshapiro NULL pointer.

Contributed by 123198121Sgshapiro Kenneth Murchison of Oceana Matrix Ltd. 123298121Sgshapiro CONTRIB: Fix wording in default dnsblaccess rejection message to 123398121Sgshapiro match dnsbl change. 123498121Sgshapiro DEVTOOLS: Add new option for access mode of statistics file, 123598121Sgshapiro confSTMODE, which specifies the permissions when initially 123698121Sgshapiro installing the sendmail statistics file. 123798121Sgshapiro LIBMILTER: Mark the listening socket as close-on-exec in case 123898121Sgshapiro a user's filter starts other applications. 123998121Sgshapiro LIBSM: Allow the MBDB initialize, lookup, and/or terminate 124098121Sgshapiro functions in SmMbdbTypes to be set to NULL. 124198121Sgshapiro MAKEMAP: Change the default file permissions for new databases from 124298121Sgshapiro 0644 to 0640. This can be overridden at compile time 124398121Sgshapiro by setting the DBMMODE macro. 124498121Sgshapiro SMRSH: Fix man page bug: replace SMRSH_CMDBIN with SMRSH_CMDDIR. 124598121Sgshapiro Problem noted by Dave Alden of Ohio State University. 124698121Sgshapiro VACATION: When listing the vacation database (-l), don't show 124798121Sgshapiro bogus timestamps for excluded (-x) addresses. Problem 124898121Sgshapiro noted by Bryan Costales. 124998121Sgshapiro New Files: 125098121Sgshapiro cf/mailer/cyrusv2.m4 125198121Sgshapiro 125294334Sgshapiro8.12.3/8.12.3 2002/04/05 125394334Sgshapiro NOTICE: In general queue files should not be moved if queue groups 125494334Sgshapiro are used. In previous versions this could cause mail 125594334Sgshapiro not to be delivered if a queue file is repeatedly moved 125694334Sgshapiro by an external process whenever sendmail moved it back 125794334Sgshapiro into the right place. Some precautions have been taken 125894334Sgshapiro to avoid moving queue files if not really necessary. 125994334Sgshapiro sendmail may use links to refer to queue files and it 126094334Sgshapiro may store the path of data files in queue files. Hence 126194334Sgshapiro queue files should not be moved unless those internals 126294334Sgshapiro are understood and the integrity of the files is not 126394334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 126494334Sgshapiro University. 126594334Sgshapiro If an error mail is created, and the mail is split across different 126694334Sgshapiro queue directories, and SuperSafe is off, then write the mail 126794334Sgshapiro to disk before splitting it, otherwise an assertion is 126894334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 126994334Sgshapiro of INTERMETA. 127094334Sgshapiro Fix possible race condition that could cause sendmail to forget 127194334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 127294334Sgshapiro Handle bogus qf files better without triggering assertions. 127394334Sgshapiro Problem noted by Guy Feltin. 127494334Sgshapiro Protect against interrupted select() call when enforcing Milter 127594334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 127694334Sgshapiro ActiveState. 127794334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 127894334Sgshapiro noted by Anne Bennett of Concordia University. 127994334Sgshapiro If privileges have been dropped, don't try to change group ID to 128094334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 128194334Sgshapiro Northern Illinois University. 128294334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 128394334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 128494334Sgshapiro of Dinoex. 128594334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 128694334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 128794334Sgshapiro Polytechnic Institute. 128894334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 128994334Sgshapiro if several mails are sent in one session and some of them 129094334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 129194334Sgshapiro Change timeout check such that cached information about a connection 129294334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 129394334Sgshapiro Based on patch from David Burns of Portland State University. 129494334Sgshapiro Properly count message size for mailstats during mail collection. 129594334Sgshapiro Problem noted by Werner Wiethege. 129694334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 129794334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 129894334Sgshapiro Provide workaround for getopt() implementations that do not catch 129994334Sgshapiro missing arguments. 130094334Sgshapiro Fix the message size calculation if the message body is replaced by 130194334Sgshapiro a milter filter and buffered file I/O is being used. 130294334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 130394334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 130494334Sgshapiro Problem noted by Werner Wiethege. 130594334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 130694334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 130794334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 130894334Sgshapiro Properly deal with a case where sendmail is called by root running 130994334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 131094334Sgshapiro Lusky of ISS Atlanta. 131194334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 131294334Sgshapiro directories are used and mail is sent to a mailing list 131394334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 131494334Sgshapiro of Concordia University. 131594334Sgshapiro Fix class map parsing code if optional key is specified. Problem 131694334Sgshapiro found by Mario Nigrovic. 131794334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 131894334Sgshapiro incoming messages. A leading dot is always stripped by the 131994334Sgshapiro SMTP receiver regardless of whether or not it is followed by 132094334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 132194334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 132294334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 132394334Sgshapiro Elvers. 132494334Sgshapiro Correct the statistics gathered for total number of connections. 132594334Sgshapiro Instead of being the exact same number as the total number 132694334Sgshapiro of messages (T line in mailstats) it now represents the 132794334Sgshapiro total number of TCP connections. 132894334Sgshapiro Be more explicit about syntax errors in addresses, especially 132994334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 133094334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 133194334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 133294334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 133394334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 133494334Sgshapiro Problem noted by Fletcher Mattox of the University of 133594334Sgshapiro Texas. 133694334Sgshapiro Change the SMTP error code for temporary map failures from 421 133794334Sgshapiro to 451. 133894334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 133994334Sgshapiro only done in one place: queue group creation). Based on 134094334Sgshapiro patch by Bryan Costales. 134194334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 134294334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 134394334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 134494334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 134594334Sgshapiro errors. By doing so, the host was marked as having a 134694334Sgshapiro temporary problem and other mail destined for that host was 134794334Sgshapiro queued for the next queue run. Problem noted by Fletcher 134894334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 134994334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 135094334Sgshapiro and Neil Rickert of Northern Illinois University. 135194334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 135294334Sgshapiro which drop the connection instead of responding to the 135394334Sgshapiro command). 135494334Sgshapiro Portability: 135594334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 135698121Sgshapiro available. 135794334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 135894334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 135994334Sgshapiro settings. Patch from Elias Halldor Agustsson of 136094334Sgshapiro Skyrr. 136194334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 136294334Sgshapiro noted by John Beck. 136394334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 136494334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 136594334Sgshapiro Rajesh Somasund of Hewlett-Packard. 136694334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 136794334Sgshapiro SMTP AUTH information. This feature was actually added in 136894334Sgshapiro 8.12.0 but a release note was not included. 136994334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 137094334Sgshapiro parameter is set and the LDAP lookup returns a temporary 137194334Sgshapiro error. 137294334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 137394334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 137494334Sgshapiro Krzysztof Oledzki. 137594334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 137694334Sgshapiro initialization as aliases are not needed for the MSP. 137794334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 137894334Sgshapiro is in use. Patch from Andrzej Filip. 137994334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 138094334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 138194334Sgshapiro This will only have an effect if a parameter is specified, 138294334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 138394334Sgshapiro it is embedded in square brackets. Problem noted by 138494334Sgshapiro Theo Van Dinter of Collective Technologies. 138594334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 138694334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 138794334Sgshapiro to allow for the proper time zone on systems where the 138894334Sgshapiro default results in misleading time stamps. That is, syslog 138994334Sgshapiro time stamps and Date headers on submitted mail will use the 139094334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 139194334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 139294334Sgshapiro by Neil Rickert of Northern Illinois University. 139394334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 139494334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 139594334Sgshapiro noted by John Beck. 139694334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 139794334Sgshapiro if queue groups are used. 139894334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 139994334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 140094334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 140194334Sgshapiro Suggested by Bryan Costales. 140294334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 140394334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 140494334Sgshapiro structure that is passed to xxfi_connect(). Notice: 140598121Sgshapiro this fix requires that sendmail and libmilter both have 140698121Sgshapiro this change; mixing versions may lead to wrong port 140794334Sgshapiro values depending on the endianness of the involved systems. 140894334Sgshapiro Problem noted by Gisle Aas of ActiveState. 140994334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 141094334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 141194334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 141294334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 141394334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 141494334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 141594334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 141694334Sgshapiro this to 1 if your LDAP client libraries include 141794334Sgshapiro ldap_memfree(). 141894334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 141994334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 142094334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 142194334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 142294334Sgshapiro VACATION: Allow root to operate on user vacation databases.

Colburn of the New Mexico 144590792Sgshapiro Institute of Mining and Technology. 144690792Sgshapiro Only log milter body replacements once instead of for each body 144790792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 144890792Sgshapiro the Finnish Meteorological Institute. 144990792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 145090792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 145190792Sgshapiro of the Finnish Meteorological Institute. 145290792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 145390792Sgshapiro needs to collect children status to avoid zombie processes. 145490792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 145590792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 145690792Sgshapiro commands are issued. This makes it consistent with normal 145790792Sgshapiro SMTP connections. 145890792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 145990792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 146090792Sgshapiro and Technology. 146190792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 146290792Sgshapiro message sender if the sender had used a deprecated RFC822 146390792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 146490792Sgshapiro Meteorological Institute. 146590792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 146690792Sgshapiro parsing.

Add configuration options for 159090792Sgshapiro different set*gid() calls to reset saved gid. Problem 159190792Sgshapiro found by Michal Zalewski. 159290792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 159390792Sgshapiro privileges by disabling debugging (command line -d flag) 159490792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 159590792Sgshapiro used. Suggested by Michal Zalewski. 159690792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 159790792Sgshapiro Problem found by Michal Zalewski. 159890792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 159990792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 160090792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 160190792Sgshapiro If debugging is turned on (-d0.10) print not just the default 160290792Sgshapiro values for configuration file and pid file but also the 160390792Sgshapiro selected values. Problem noted by Brad Chapman. 160490792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 160590792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 160690792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 160790792Sgshapiro this only applied to hostname canonification. Problem 160890792Sgshapiro noted by Bill Fenner of AT&T Research. 160990792Sgshapiro Ignore comments in NIS host records when trying to find the 161090792Sgshapiro canonical name for a host. 161190792Sgshapiro When sendmail has extra privileges, limit mail submission command 161290792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 161390792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 161490792Sgshapiro suggestion from Michal Zalewski. 161590792Sgshapiro Portability: 161690792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 161790792Sgshapiro `uname` does not given complete information. 161890792Sgshapiro Problem noted by Keith Neufeld of the Cessna 161990792Sgshapiro Aircraft Company. 162090792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 162190792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 162290792Sgshapiro Avoid compiler warnings by not using pointers to pass 162390792Sgshapiro integers.

You need to create a new user and 165690792Sgshapiro a new group before installing sendmail (both called smmsp by 165790792Sgshapiro default). The installation process tries to install 165890792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 165990792Sgshapiro default.

Suggested 167090792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 167190792Sgshapiro (IdS). 167290792Sgshapiro Fixed problem of a global variable being used for a timeout jump 167390792Sgshapiro point where the variable could become overused for more than 167490792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 167590792Sgshapiro a corrupted stack causing a core dump. The timeout is now 167690792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 167790792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 167890792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 167990792Sgshapiro checks (group ID of RunAsUser). This allows use of a 168090792Sgshapiro set-group-ID sendmail binary for initial message submission 168190792Sgshapiro and no set-user-ID root sendmail is needed. For details 168290792Sgshapiro see sendmail/SECURITY. 168390792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 168490792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 168590792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 168690792Sgshapiro with a fallback of sendmail.cf as configuration file. See 168790792Sgshapiro sendmail/SECURITY. 168890792Sgshapiro New configuration file option UseMSP to allow group writable queue 168990792Sgshapiro files if the group is the same as that of a set-group-ID 169090792Sgshapiro sendmail binary. See sendmail/SECURITY. 169190792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 169290792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 169390792Sgshapiro is sendmail.cf (to be backward compatible). This selection 169490792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 169590792Sgshapiro file: client or mta). See sendmail/SECURITY. 169690792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 169790792Sgshapiro command has been removed. 169890792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 169990792Sgshapiro at compile time or per host (ruleset). 170090792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 170190792Sgshapiro used to look up local mail recipients; the default value 170290792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 170390792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 170490792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 170590792Sgshapiro long, to accomodate envelope splitting. File systems with 170690792Sgshapiro a 14 character file name length limit are no longer 170790792Sgshapiro supported. 170890792Sgshapiro Recipient list used for delivery now gets internally ordered by 170990792Sgshapiro hostsignature (character string version of MX RR). This orders 171090792Sgshapiro recipients for the same MX RR's together meaning smaller 171190792Sgshapiro portions of the list need to be scanned (instead of the whole 171290792Sgshapiro list) each delivery() pass to determine piggybacking. The 171390792Sgshapiro significance of the change is better the larger the recipient 171490792Sgshapiro list. Hostsignature is now created during recipient list 171590792Sgshapiro creation rather than just before delivery. 171690792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 171790792Sgshapiro piggybacking (called coincidental) extended to coattail 171890792Sgshapiro piggybacking. Rather than complete MX RR matching 171990792Sgshapiro (coincidental) piggybacking is done if just the lowest value 172090792Sgshapiro preference matches (coattail). 172190792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 172290792Sgshapiro try other MX hosts if available. 172390792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 172490792Sgshapiro outgoing (client-side) SMTP Authentication. 172590792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 172690792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 172790792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 172890792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 172990792Sgshapiro A new ruleset authinfo can be used to return client side 173090792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 173190792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 173290792Sgshapiro removed in future versions. 173390792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 173490792Sgshapiro requires 334. Mercury 1.48 is a known offender. 173590792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 173690792Sgshapiro for the security layer in SMTP AUTH (SASL). See 173790792Sgshapiro doc/op/op.me for details. 173890792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 173990792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 174090792Sgshapiro signed the presented certificate, the CN and the MD5 hash 174190792Sgshapiro of the presented certificate, respectively. 174290792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 174390792Sgshapiro New ruleset srv_features to enable/disable certain features in the 174490792Sgshapiro server per connection. See doc/op/op.me for details. 174590792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 174690792Sgshapiro recipient; useful to decide whether a conection is secure 174790792Sgshapiro enough on a per recipient basis. 174890792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 174990792Sgshapiro for STARTTLS. 175090792Sgshapiro If no certificate has been requested, the macro {verify} has the 175190792Sgshapiro value "NOT". 175290792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 175390792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 175490792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 175590792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 175690792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 175790792Sgshapiro really required. This change results in a noticable 175890792Sgshapiro performance gains on most machines. Moreover, if shared 175990792Sgshapiro memory is in use, reuse the key several times. 176090792Sgshapiro Add queue groups which can be used to group queue directories with 176190792Sgshapiro the same behavior together. See doc/op/op.me for details. 176290792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 176390792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 176490792Sgshapiro are initially sorted which may result in faster envelope 176590792Sgshapiro splitting. If the mail is submitted directly from the 176690792Sgshapiro command line, then the value also limits the number of 176790792Sgshapiro processes to deliver the envelopes; if more envelopes are 176890792Sgshapiro created they are only queued up and must be taken care of 176990792Sgshapiro by a queue run. 177090792Sgshapiro The check for 'enough disk space' now pays attention to which file 177190792Sgshapiro system each queue directory resides in. 177290792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 177390792Sgshapiro New option QueueFileMode for the default permissions of queue files. 177490792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 177590792Sgshapiro group (one or more queues in a multi-queue environment 177690792Sgshapiro collected together) to process the same work list at the 177790792Sgshapiro same time. 177890792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 177990792Sgshapiro active queue runner processes. 178090792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 178190792Sgshapiro runners per queue group. 178290792Sgshapiro Queue member selection by substring pattern matching now allows 178390792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 178490792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 178590792Sgshapiro of the queue that match during processing. 178690792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 178790792Sgshapiro periodically forking a child to process the queue, a single 178890792Sgshapiro child is forked for each queue that sleeps between queue 178990792Sgshapiro runs. A SIGHUP signal can be sent to restart this 179090792Sgshapiro persistent queue runner. 179190792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 179290792Sgshapiro sendmail process which only runs the queue at an interval: 179390792Sgshapiro sendmail -q15m). 179490792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 179590792Sgshapiro Proposed by Thom O'Connor. 179690792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 179790792Sgshapiro unless the new -qf option or -v is used. 179890792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 179990792Sgshapiro several queue runners are started by hand to avoid contention. 180090792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 180190792Sgshapiro of the qf file (older entries first). 180290792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 180390792Sgshapiro a client to specify an amount of time within which an e-mail 180490792Sgshapiro should be delivered. New option DeliverByMin added to set the 180590792Sgshapiro minimum amount of time or disable the extension. 180690792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 180790792Sgshapiro not allowed unless escaped or quoted. 180890792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 180990792Sgshapiro by Leif Johansson of Stockholm University, which was based on 181090792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 181190792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 181290792Sgshapiro Technology, Stockholm, Sweden. 181390792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 181490792Sgshapiro behavior (no MX lookups), put the name in square brackets. 181590792Sgshapiro Proposed by Thom O'Connor. 181690792Sgshapiro Use shared memory to store free space of filesystems that are used 181790792Sgshapiro for queues, if shared memory is available and if a key is set 181890792Sgshapiro via SharedMemoryKey. This minimizes the number of system 181990792Sgshapiro calls to check the available space. See doc/op/op.me for 182090792Sgshapiro details. 182190792Sgshapiro If shared memory is compiled in the option -bP can be used to print 182290792Sgshapiro the number of entries in the queue(s). 182390792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 182490792Sgshapiro and the usual documentation for details. 182590792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 182690792Sgshapiro Remove '-U' (initial user submission) command line option as 182790792Sgshapiro announced in 8.10. 182890792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 182990792Sgshapiro New macro {addr_type} which contains whether the current address is 183090792Sgshapiro an envelope sender or recipient address. Suggested by 183190792Sgshapiro Neil Rickert of Northern Illinois University. 183290792Sgshapiro Two new options for host maps: -d (retransmission timeout), 183390792Sgshapiro -r (number of retries). 183490792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 183590792Sgshapiro separator such that a lookup can return both an attribute 183690792Sgshapiro and value separated by the given separator. 183790792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 183890792Sgshapiro to map class arith. 183990792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 184090792Sgshapiro (errors that occur when sending an error message) are dropped. 184190792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 184290792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 184390792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 184490792Sgshapiro requirements for files containing secret keys. This is 184590792Sgshapiro necessary for the MSP if client authentification is used. 184690792Sgshapiro Properly handle quoted filenames for class files (to allow for 184790792Sgshapiro filenames with spaces). 184890792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 184990792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 185090792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 185190792Sgshapiro {if_addr_out} address of interface of outgoing connection. 185290792Sgshapiro {if_family_out} family of interface of outgoing connection. 185390792Sgshapiro The latter two are only set if the interface does not belong 185490792Sgshapiro to the loopback net. 185590792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 185690792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 185790792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 185890792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 185990792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 186090792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 186190792Sgshapiro all connections for a single delivery attempt to succeed. 186290792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 186390792Sgshapiro a threshold number of recipients has been rejected (option 186490792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 186590792Sgshapiro Development Group. 186690792Sgshapiro New option DelayLA to delay connections if the load averages 186790792Sgshapiro exceeds the specified value. The default of 0 does not 186890792Sgshapiro change the previous behavior. A value greater than 0 186990792Sgshapiro will cause sendmail to sleep for one second on most 187090792Sgshapiro SMTP commands and before accepting connections if that 187190792Sgshapiro load average is exceeded. 187290792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 187390792Sgshapiro recipients that are sent during a connection to a mailer. 187490792Sgshapiro This also introduces a new mailer field 'r' which defines 187590792Sgshapiro the maximum number of recipients (defaults to 100). 187690792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 187790792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 187890792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 187990792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 188090792Sgshapiro instead. 188190792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 188290792Sgshapiro builtin mailer pathnames. Use TCP instead. 188390792Sgshapiro PH map code updated to use the new libphclient API instead of the 188490792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 188590792Sgshapiro University of Illinois at Urbana-Champaign. 188690792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 188790792Sgshapiro for direct (command line) submissions. 188890792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 188990792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 189090792Sgshapiro Hagino of the KAME Project. 189190792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 189290792Sgshapiro whose content is rewritten similar to Reply-To:. 189390792Sgshapiro Proposed by Andrzej Filip. 189490792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 189590792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 189690792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 189790792Sgshapiro AUTH/STARTTLS related logfile entries. 189890792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 189990792Sgshapiro before logging. 190090792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 190190792Sgshapiro (at LogLevel 9/10 or higher). 190290792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 190390792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 190490792Sgshapiro in which most commands are rejected due to check_relay or 190590792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 190690792Sgshapiro Change logging format for cloned envelopes to be similar to that for 190790792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 190890792Sgshapiro of the Universitat Regensburg. 190990792Sgshapiro Added libsm, a C library of general purpose abstractions including 191090792Sgshapiro assertions, tracing and debugging with named debug categories, 191190792Sgshapiro exception handling, malloc debugging, resource pools, 191290792Sgshapiro portability abstractions, and an extensible buffered I/O 191390792Sgshapiro package. It will at some point replace libsmutil. 191490792Sgshapiro See libsm/index.html for details. 191590792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 191690792Sgshapiro care of by fork() and exit(). 191790792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 191890792Sgshapiro more consistent portablity amongst different platforms 191990792Sgshapiro new and old (from new libsm). 192090792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 192190792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 192290792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 192390792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 192490792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 192590792Sgshapiro synchronizations calls. 192690792Sgshapiro Add per-recipient status information to mailq -v output. 192790792Sgshapiro T_ANY queries are no longer used by sendmail. 192890792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 192990792Sgshapiro too (see include/sm/cdefs.h for more info). 193090792Sgshapiro sendmail -d now has general support for named debug categories. 193190792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 193290792Sgshapiro for details. 193390792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 193490792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 193590792Sgshapiro generated by this condition were illegal (not RFC conform). 193690792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 193790792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 193890792Sgshapiro mailer and the recipient has hence been rejected during the 193990792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 194090792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 194190792Sgshapiro that do not have postmaster defined. If an email was sent 194290792Sgshapiro from an address to which a DSN cannot be returned and 194390792Sgshapiro in which at least one recipient address is non-deliverable, 194490792Sgshapiro then that email had been delivered in each queue run. 194590792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 194690792Sgshapiro degli Studi dell'Insubria. 194790792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 194890792Sgshapiro i.e., the corresponding code is always compiled in now. 194990792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 195090792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 195190792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 195290792Sgshapiro attempting to canonify a hostname, some broken nameservers 195390792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 195490792Sgshapiro lookups. If you want to excuse this behavior, use this new 195590792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 195690792Sgshapiro Mark Roth of the University of Illinois at 195790792Sgshapiro Urbana-Champaign. 195890792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 195990792Sgshapiro noted by Joy Latten of IBM. 196090792Sgshapiro ConnectionRateThrottle limits the number of connections per second 196190792Sgshapiro to each daemon individually, not the overall number of 196290792Sgshapiro connections. 196390792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 196490792Sgshapiro sendmail to use a default alias schema as outlined in the 196590792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 196690792Sgshapiro cf/README. 196790792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 196890792Sgshapiro the first character after the class name is not a '/' or a 196990792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 197090792Sgshapiro rest of the line will be parsed as a map lookup. This 197190792Sgshapiro allows classes to be filled via a map lookup. See op.me 197290792Sgshapiro for more syntax information. Specifically, this can be 197390792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 197490792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 197590792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 197690792Sgshapiro example). 197790792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 197890792Sgshapiro the default schema used in the above two items. 197990792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 198090792Sgshapiro warning if a program being run from a mailer or file class 198190792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 198290792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 198390792Sgshapiro if a program being run from a mailer or file class 198490792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 198590792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 198690792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 198790792Sgshapiro (without quotes) will disable this and return to the 198890792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 198990792Sgshapiro Suggested by Bryan Stansell of GNAC. 199090792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 199190792Sgshapiro HELO/EHLO commands. 199290792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 199390792Sgshapiro possible protocol family which may be used for outgoing 199490792Sgshapiro connections. Restrictions placed on one family only affect 199590792Sgshapiro outgoing connections on that particular family. Because of 199690792Sgshapiro this change, the ${client_flags} macro is not set until the 199790792Sgshapiro connection is established. Based on patch from Motonori 199890792Sgshapiro Nakamura of Kyoto University. 199990792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 200090792Sgshapiro when the -bv option is given by users who are neither root 200190792Sgshapiro nor the TrustedUser so users can not read private aliases, 200290792Sgshapiro forwards, or :include: files. It also will override the -v 200390792Sgshapiro (verbose) command line option. 200490792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 200590792Sgshapiro address can't be used for the outgoing connection, fall 200690792Sgshapiro back to the settings in ClientPortOptions (if set). 200790792Sgshapiro Problem noted by John Beck of Sun Microsystems. 200890792Sgshapiro New named config file rule check_data for DATA command (input: 200990792Sgshapiro number of recipients). Based on patch from Mark Roth of 201090792Sgshapiro the University of Illinois at Urbana-Champaign. 201190792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 201290792Sgshapiro can be specified using the '#' option character. For 201390792Sgshapiro example, 'ETRN #queuegroup'. 201490792Sgshapiro If an LDAP server times out or becomes unavailable, close the 201590792Sgshapiro current connection and reopen to get to one of the fallback 201690792Sgshapiro servers. Patch from Paul Hilchey of the University of 201790792Sgshapiro British Columbia. 201890792Sgshapiro Make default error number on $#error messages 550 instead of 501 201990792Sgshapiro because 501 is not allowed on all commands. 202090792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 202190792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 202290792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 202390792Sgshapiro if required. 202490792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 202590792Sgshapiro class instead. 202690792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 202790792Sgshapiro "IPv6:" tag to identify the address properly. For example, 202890792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 202990792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 203090792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 203190792Sgshapiro MTA is running. For example, during a queue run. 203290792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 203390792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 203490792Sgshapiro Nelson of IBM. 203590792Sgshapiro The maximum number of commands before the MTA slows down when too 203690792Sgshapiro many "light weight" commands have been received are now 203790792Sgshapiro configurable during compile time. The current values and 203890792Sgshapiro their defaults are: 203990792Sgshapiro MAXBADCOMMANDS 25 unknown commands 204090792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 204190792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 204290792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 204390792Sgshapiro MAXETRNCOMMANDS 8 ETRN 204490792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 204590792Sgshapiro Costales of SL3D, Inc. 204690792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 204790792Sgshapiro ${MyMacro} is defined but also that it is not empty. 204890792Sgshapiro Properly quote usernames with special characters if they are used 204990792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 205090792Sgshapiro Meteorological Institute. 205190792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 205290792Sgshapiro messages for messages for mailing list expanded addresses 205390792Sgshapiro which are not delivered on the initial attempt. 205490792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 205590792Sgshapiro the final dot has been sent to avoid affecting future 205690792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 205790792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 205890792Sgshapiro file systems that require to call fsync() for a directory 205990792Sgshapiro if the meta-data in it has been changed. This should be 206090792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 206190792Sgshapiro See sendmail/README for further information. 206290792Sgshapiro Avoid file locking deadlock when updating the statistics file if 206390792Sgshapiro sendmail is signaled to terminate. Problem noted by 206490792Sgshapiro Christophe Wolfhugel of France Telecom. 206590792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 206690792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 206790792Sgshapiro the Finnish Meteorological Institute. 206890792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 206990792Sgshapiro from Peter A. Friend of EarthLink. 207090792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 207190792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 207290792Sgshapiro flora.ca. 207390792Sgshapiro Portability: 207490792Sgshapiro Remove support for AIX 2, which supports only 14 character 207590792Sgshapiro filenames and is outdated anyway. Suggested by 207690792Sgshapiro Valdis Kletnieks of Virginia Tech. 207790792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 207890792Sgshapiro i.e., use default /usr/sbin, change owner/group 207990792Sgshapiro of man pages and user-executable to root/sys, set 208090792Sgshapiro optimization limit to 0 (unlimited). Based on patch 208190792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 208290792Sgshapiro Hurtta of the Finnish Meteorological Institute. 208390792Sgshapiro Do not assume LDAP support is installed by default under 208490792Sgshapiro Solaris 8 and later. 208590792Sgshapiro Add support for OpenUNIX. 208690792Sgshapiro CONFIG: Increment version number of config file to 10. 208790792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 208890792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 208990792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 209090792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 209190792Sgshapiro temporary lookup failures. 209290792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 209390792Sgshapiro action to be taken by aborting the search for domain names 209490792Sgshapiro or IP nets. 209590792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 209690792Sgshapiro relay address as long as the other part allows the email 209790792Sgshapiro to get through. 209890792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 209990792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 210090792Sgshapiro entry like user+*@domain. This allows handling of details by 210190792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 210290792Sgshapiro introduced to match only non-empty details of addresses. 210390792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 210490792Sgshapiro and hence there is no required order within the MAILER 210590792Sgshapiro section anymore except for MAILER(`uucp') which must come 210690792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 210790792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 210890792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 210990792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 211090792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 211190792Sgshapiro in the access map which returns OK or RELAY actually 211290792Sgshapiro terminates check_* ruleset checking. 211390792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 211490792Sgshapiro tls_rcpt, see cf/README for details. 211590792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 211690792Sgshapiro STARTTLS has been used to "(version=${tls_version} 211790792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 211890792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 211990792Sgshapiro options friends/haters instead of "To:" and enable 212090792Sgshapiro specification of whole domains instead of just users. 212190792Sgshapiro Notice: this change is not backward compatible. 212290792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 212390792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 212490792Sgshapiro cf/README for details. 212590792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 212690792Sgshapiro the access map.

New option -D mbdb specifies the 225290792Sgshapiro mailbox database type. 225390792Sgshapiro MAIL.LOCAL: New option "-h filename" which instructs mail.local to 225490792Sgshapiro deliver the mail to the named file in the user's home 225590792Sgshapiro directory instead of the system mail spool area. Based on 225690792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 225790792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 225890792Sgshapiro doesn't truncate the statistics file. 225990792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 226090792Sgshapiro instead of white space. 226190792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 226290792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 226390792Sgshapiro Meteorological Institute. 226490792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 226590792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 226690792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 226790792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 226890792Sgshapiro instead of syslog. 226990792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 227090792Sgshapiro in the password file. The -f and -m options must be used 227190792Sgshapiro to specify the database and message file since there is no 227290792Sgshapiro home directory for the default settings for these options. 227390792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 227490792Sgshapiro local mail recipients; it reads the MailboxDatabase option 227590792Sgshapiro from the sendmail.cf file. New option -C cffile which 227690792Sgshapiro specifies the path of the sendmail.cf file. 227790792Sgshapiro New Directories: 227890792Sgshapiro libmilter/docs 227990792Sgshapiro New Files: 228090792Sgshapiro cf/cf/README 228190792Sgshapiro cf/cf/submit.cf 228290792Sgshapiro cf/cf/submit.mc 228390792Sgshapiro cf/feature/authinfo.m4 228490792Sgshapiro cf/feature/compat_check.m4 228590792Sgshapiro cf/feature/enhdnsbl.m4 228690792Sgshapiro cf/feature/msp.m4 228790792Sgshapiro cf/feature/local_no_masquerade.m4 228890792Sgshapiro cf/feature/lookupdotdomain.m4 228990792Sgshapiro cf/feature/preserve_luser_host.m4 229090792Sgshapiro cf/feature/preserve_local_plus_detail.m4 229190792Sgshapiro cf/feature/queuegroup.m4 229290792Sgshapiro cf/sendmail.schema 229390792Sgshapiro contrib/dnsblaccess.m4 229490792Sgshapiro devtools/M4/UNIX/sm-test.m4 229590792Sgshapiro devtools/OS/OpenUNIX.5.i386 229690792Sgshapiro editmap/* 229790792Sgshapiro include/sm/* 229890792Sgshapiro libsm/* 229990792Sgshapiro libsmutil/cf.c 230090792Sgshapiro libsmutil/err.c 230190792Sgshapiro sendmail/SECURITY 230290792Sgshapiro sendmail/TUNING 230390792Sgshapiro sendmail/bf.c 230490792Sgshapiro sendmail/bf.h 230590792Sgshapiro sendmail/sasl.c 230690792Sgshapiro sendmail/sm_resolve.c 230790792Sgshapiro sendmail/sm_resolve.h 230890792Sgshapiro sendmail/tls.c 230990792Sgshapiro Deleted Files: 231090792Sgshapiro cf/feature/rbl.m4 231190792Sgshapiro cf/ostype/aix2.m4 231290792Sgshapiro devtools/OS/AIX.2 231390792Sgshapiro include/sendmail/cdefs.h 231490792Sgshapiro include/sendmail/errstring.h 231590792Sgshapiro include/sendmail/useful.h 231690792Sgshapiro libsmutil/errstring.c 231790792Sgshapiro sendmail/bf_portable.c 231890792Sgshapiro sendmail/bf_portable.h 231990792Sgshapiro sendmail/bf_torek.c 232090792Sgshapiro sendmail/bf_torek.h 232190792Sgshapiro sendmail/clock.c 232290792Sgshapiro Renamed Files: 232390792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 232490792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 232590792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 232690792Sgshapiro 2327120256Sgshapiro8.11.7/8.11.7 2003/03/29 2328120256Sgshapiro SECURITY: Fix a remote buffer overflow in header parsing by 2329120256Sgshapiro dropping sender and recipient header comments if the 2330120256Sgshapiro comments are too long.

If sendmail needs to drop 281764562Sgshapiro these privileges and the operating system doesn't set the 281864562Sgshapiro saved-uid as well, exit with an error. Problem noted by 281964562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 282064562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 282164562Sgshapiro it populates. It is possible that some broken 282264562Sgshapiro implementations of snprintf() exist that do not do this. 282364562Sgshapiro Systems in this category should compile with 282464562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 282564562Sgshapiro system and report broken implementations to 282664562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 282764562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 282864562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 282964562Sgshapiro Implementation influenced by the example programs of 283064562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 283164562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 283264562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 283364562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 283464562Sgshapiro cf/README and doc/op/op.*. 283564562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 283664562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 283764562Sgshapiro ${server_name}, and ${server_addr}. These are documented 283864562Sgshapiro in cf/README and doc/op/op.*. 283964562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 284064562Sgshapiro random data. 284164562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 284264562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 284364562Sgshapiro try to use STARTTLS despite the security problems. 284464562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 284564562Sgshapiro support encryption. Based on code contributed by Tim 284664562Sgshapiro Martin of CMU. 284764562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 284864562Sgshapiro strength factor. 284964562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 285064562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 285164562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 285264562Sgshapiro of CMU. 285364562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 285464562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 285564562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 285664562Sgshapiro Fix the default family selection for DaemonPortOptions. As 285764562Sgshapiro documented, unless a family is specified in a 285864562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 285964562Sgshapiro also the default if no DaemonPortOptions value is set. 286064562Sgshapiro Therefore, IPv6 users should configure additional sockets 286164562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 286264562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 286364562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 286464562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 286564562Sgshapiro the interface information for an outgoing connection. 286664562Sgshapiro Not doing so was creating a mismatch between the socket 286764562Sgshapiro family and address used in subsequent connections if the 286864562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 286964562Sgshapiro by John Beck of Sun Microsystems. 287064562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 287164562Sgshapiro family based on the IP address. ${if_family} is no longer 287264562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 287364562Sgshapiro of Sun Microsystems. 287464562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 287564562Sgshapiro macros for both the incoming interface address/family and 287664562Sgshapiro the outgoing interface address/family. In order for M=b 287764562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 287864562Sgshapiro the incoming information in the queue file for later 287964562Sgshapiro delivery attempts. 288064562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 288164562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 288264562Sgshapiro smoe.org. 288364562Sgshapiro Add more vigilance in checking for putc() errors on output streams 288464562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 288564562Sgshapiro noted by Graeme Hewson of Oracle. 288664562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 288764562Sgshapiro Problem noted by Ajay Matia. 288864562Sgshapiro Under certain circumstances, an address could be listed as deferred 288964562Sgshapiro but would be bounced back to the sender as failed to be 289064562Sgshapiro delivered when it really should have been queued. Problem 289164562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 289264562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 289364562Sgshapiro the SMTP transaction out of sync.

Problem noted by Neil Rickert 289864562Sgshapiro of Northern Illinois University. 289964562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 290064562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 290164562Sgshapiro Convert the free disk space shown in a control socket status query 290264562Sgshapiro to kilobyte units. 290364562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 290464562Sgshapiro looking up the hostname, requeue the message for a later 290564562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 290664562Sgshapiro Polytechnic. 290764562Sgshapiro Under the proper circumstances, failed connections would be recorded 290864562Sgshapiro as "Bad file number" instead of "Connection failed" in the 290964562Sgshapiro queue file and persistent host status. Problem noted by 291064562Sgshapiro Graeme Hewson of Oracle. 291164562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 291264562Sgshapiro within the hoststatus directory (e.g., lost+found). 291364562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 291464562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 291564562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 291664562Sgshapiro If a message data file can't be opened at delivery time, panic and 291764562Sgshapiro abort the attempt instead of delivering a message that 291864562Sgshapiro states "<<< No Message Collected >>>". 291964562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 292064562Sgshapiro restrictive.

Thomas Consulting. 292264562Sgshapiro Preserve source port number instead of replacing it with the ident 292364562Sgshapiro port number (113). 292464562Sgshapiro Document the queue status characters in the mailq man page. 292564562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 292664562Sgshapiro Process queued items in which none of the recipient addresses have 292764562Sgshapiro host portions (or there are no recipients). Problem noted 292864562Sgshapiro by Valdis Kletnieks of Virginia Tech. 292964562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 293064562Sgshapiro only the first to open the connection is allowed to close 293164562Sgshapiro it so a later map close doesn't break the connection for 293264562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 293364562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 293464562Sgshapiro authentication.

This option and 319364562Sgshapiro its use is deprecated and will be removed from a future 319464562Sgshapiro version of sendmail. 319564562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 319664562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 319764562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 319864562Sgshapiro (IdS). 319964562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 320064562Sgshapiro a large number of files. See cf/README for more details. 320164562Sgshapiro The directory structure of the distribution has changed slightly 320264562Sgshapiro for easier code sharing among the programs. 320364562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 320464562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 320564562Sgshapiro which hold the client's authentication credentials, 320664562Sgshapiro the mechanism used for authentication, and the 320764562Sgshapiro authorization identity (i.e., the AUTH= parameter if 320864562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 320964562Sgshapiro On systems which use the Torek stdio library (all of the BSD 321064562Sgshapiro distributions), use memory-buffered files to reduce 321164562Sgshapiro file system overhead by not creating temporary files on 321264562Sgshapiro disk. Contributed by Exactis.com, Inc. 321364562Sgshapiro New option DataFileBufferSize to control the maximum size of a 321464562Sgshapiro memory-buffered data (df) file before a disk-based file is 321564562Sgshapiro used. Contributed by Exactis.com, Inc. 321664562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 321764562Sgshapiro memory-buffered transcript (xf) file before a disk-based 321864562Sgshapiro file is used. Contributed by Exactis.com, Inc. 321964562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 322064562Sgshapiro now listen on several different ports. Use: 322164562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 322264562Sgshapiro to run a Message Submission Agent (MSA); this is turned 322364562Sgshapiro on by default in m4-generated .cf files; it can be turned 322464562Sgshapiro off with FEATURE(`no_default_msa'). 322564562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 322664562Sgshapiro begin using RFC 2476 Message Submission for initial user 322764562Sgshapiro message submission. XUSR may disappear from a future release. 322864562Sgshapiro The new '-G' (relay (gateway) submission) command line option 322964562Sgshapiro indicates that the message being submitted from the command 323064562Sgshapiro line is for relaying, not initial submission. This means 323164562Sgshapiro the message will be rejected if the addresses are not fully 323264562Sgshapiro qualified and no canonicalization will be done. Future 323364562Sgshapiro releases may even reject improperly formed messages. 323464562Sgshapiro The '-U' (initial user submission) command line option is 323564562Sgshapiro deprecated and may be removed from a future release. 323664562Sgshapiro Mail user agents should begin using '-G' to indicate that 323764562Sgshapiro this is a relay submission (the inverse of -U). 323864562Sgshapiro The next release of sendmail will assume that any message submitted 323964562Sgshapiro from the command line is an initial user submission and act 324064562Sgshapiro accordingly. 324164562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 324264562Sgshapiro program or deliver to file as the owner of that file, the 324364562Sgshapiro address is marked as unsafe. This means if RunAsUser is 324464562Sgshapiro set, users won't be able to use programs or delivery to 324564562Sgshapiro files in their .forward files. Administrators can override 324664562Sgshapiro this by setting the DontBlameSendmail option to the new 324764562Sgshapiro setting NonRootSafeAddr. 324864562Sgshapiro Allow group or world writable directories if the sticky bit is set 324964562Sgshapiro on the directory and DontBlameSendmail is set to 325064562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 325164562Sgshapiro InCert Software. 325264562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 325364562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 325464562Sgshapiro set in the DontBlameSendmail option. Requested by many. 325564562Sgshapiro New Timeout.control option to limit the total time spent satisfying 325664562Sgshapiro a control socket request. 325764562Sgshapiro New Timeout.resolver options for controlling BIND resolver 325864562Sgshapiro settings: 325964562Sgshapiro Timeout.resolver.retrans 326064562Sgshapiro Sets the resolver's retransmission time interval (in 326164562Sgshapiro seconds).

Sets both Timeout.resolver.retry.first 327364562Sgshapiro and Timeout.resolver.retry.normal. 327464562Sgshapiro Timeout.resolver.retry.first 327564562Sgshapiro Sets the number of times to retransmit a resolver 327664562Sgshapiro query for the first attempt to deliver a message. 327764562Sgshapiro Timeout.resolver.retry.normal 327864562Sgshapiro Sets the number of times to retransmit a resolver 327964562Sgshapiro query for all resolver lookups except the first 328064562Sgshapiro delivery attempt. 328164562Sgshapiro Contributed by Exactis.com, Inc. 328264562Sgshapiro Support multiple queue directories. To use multiple queues, supply 328364562Sgshapiro a QueueDirectory option value ending with an asterisk. For 328464562Sgshapiro example, /var/spool/mqueue/q* will use all of the 328564562Sgshapiro directories or symbolic links to directories beginning with 328664562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 328764562Sgshapiro mind, the queue directory structure should not be changed 328864562Sgshapiro while sendmail is running. Queue runs create a separate 328964562Sgshapiro process for running each queue unless the verbose flag is 329064562Sgshapiro given on a non-daemon queue run. New items are randomly 329164562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 329264562Sgshapiro Support different directories for qf, df, and xf queue files; if 329364562Sgshapiro subdirectories or symbolic links to directories of those names 329464562Sgshapiro exist in the queue directories, they are used for the 329564562Sgshapiro corresponding queue files. Keep in mind, the queue 329664562Sgshapiro directory structure should not be changed while sendmail is 329764562Sgshapiro running. Proposed by Mathias Koerber of Singapore 329864562Sgshapiro Telecommunications Ltd. 329964562Sgshapiro New queue file naming system which uses a filename guaranteed to be 330064562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 330164562Sgshapiro without fancy file system locking. Queued items can be 330264562Sgshapiro moved between queues easily. Contributed by Exactis.com, 330364562Sgshapiro Inc. 330464562Sgshapiro Messages which are undeliverable due to temporary address failures 330564562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 330664562Sgshapiro set. Contributed by Exactis.com, Inc. 330764562Sgshapiro New command line option '-L tag' which sets the identifier used for 330864562Sgshapiro syslog. Contributed by Exactis.com, Inc. 330964562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 331064562Sgshapiro avoids opening and reading each queue file when preparing 331164562Sgshapiro to run the queue.

This can be used with LMTP 332764562Sgshapiro local delivery agents which listen on a named socket. An 332864562Sgshapiro example mailer might be: 332964562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 333064562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 333164562Sgshapiro A=FILE /var/run/lmtpd 333264562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 333364562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 333464562Sgshapiro instead. 333564562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 333664562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 333764562Sgshapiro connections), IPC (which will be deprecated in a future 333864562Sgshapiro version), and FILE (for UNIX domain socket delivery). 333964562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 334064562Sgshapiro flags. 334164562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 334264562Sgshapiro body of the original message on delivery status 334364562Sgshapiro notifications. 334464562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 334564562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 334664562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 334764562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 334864562Sgshapiro Steve Schweinhart of America Online. 334964562Sgshapiro Warn if OperatorChars is set multiple times.

See SMTP 336564562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 336664562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 336764562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 336864562Sgshapiro similar to check_rcpt etc. 336964562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 337064562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 337164562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 337264562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 337364562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 337464562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 337564562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 337664562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 337764562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 337864562Sgshapiro the corresponding DSN parameter values. Proposed by 337964562Sgshapiro Mathias Herberts. 338064562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 338164562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 338264562Sgshapiro before the message has been collected, thereafter it holds 338364562Sgshapiro the message size as computed by sendmail (and can be used 338464562Sgshapiro in check_compat). 338564562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 338664562Sgshapiro sendmail is using instead of the value of the DeliveryMode 338764562Sgshapiro option. 338864562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 338964562Sgshapiro Drop explicit From: if same as what would be generated only if it is 339064562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 339164562Sgshapiro Write pid to file also if sendmail only processes the queue. 339264562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 339364562Sgshapiro Log "low on disk space" only when necessary. 339464562Sgshapiro New macro ${load_avg} can be used to check the current load average. 339564562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 339664562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 339764562Sgshapiro is set. 339864562Sgshapiro Flag -S for maps to specify the character which is substituted 339964562Sgshapiro for spaces (instead of the default given by O BlankSub). 340064562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 340164562Sgshapiro This flag is set by default for the host map. Based on a 340264562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 340364562Sgshapiro Open maps only on demand, not at startup. 340464562Sgshapiro Log warning about unsupported IP address families. 340564562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 340664562Sgshapiro of the sum of all headers. This can be used to prevent 340764562Sgshapiro a denial-of-service attack. 340864562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 340964562Sgshapiro headers and parameters within those headers. This option 341064562Sgshapiro is intended to protect mail user agents from buffer 341164562Sgshapiro overflow attacks. 341264562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 341364562Sgshapiro alias recursion. 341464562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 341564562Sgshapiro Map type syslog to log the key via syslogd. 341664562Sgshapiro Entries in the alias file can be continued by putting a backslash 341764562Sgshapiro directly before the newline. 341864562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 341964562Sgshapiro dead.letter file, formerly hardcoded to 342064562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 342164562Sgshapiro default), sendmail will not attempt to save to a 342264562Sgshapiro system-wide dead.letter file if it can not bounce the mail 342364562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 342464562Sgshapiro file as it has in the past when the dead.letter file 342564562Sgshapiro could not be opened. 342664562Sgshapiro New option PidFile to define the location of the pid file. The 342764562Sgshapiro value of this option is macro expanded. 342864562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 342964562Sgshapiro process title shown in 'ps' listings. 343064562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 343164562Sgshapiro (along with the already existing macros): 343264562Sgshapiro ${daemon_info} Daemon information, e.g. 343364562Sgshapiro SMTP+queueing@00:30:00 343464562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 343564562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 343664562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 343764562Sgshapiro ${daemon_port} Daemon port, e.g., 25 343864562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 343964562Sgshapiro New macros especially for virtual hosting: 344064562Sgshapiro ${if_name} hostname of interface of incoming connection. 344164562Sgshapiro ${if_addr} address of interface of incoming connection. 344264562Sgshapiro The latter is only set if the interface does not belong to the 344364562Sgshapiro loopback net. 344464562Sgshapiro If a message being accepted via a method other than SMTP and 344564562Sgshapiro would be rejected by a header check, do not send the message. 344664562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 344764562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 344864562Sgshapiro Provide header value as quoted string in the macro 344964562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 345064562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 345164562Sgshapiro The length of the header value is stored in ${hdrlen}. 345264562Sgshapiro H*: allows to specify a default ruleset for header checks. This 345364562Sgshapiro ruleset will only be called if the individual header does 345464562Sgshapiro not have its own ruleset assigned. Suggested by Jan 345564562Sgshapiro Krueger of Unix-AG of University of Hannover. 345664562Sgshapiro The name of the header field stored in ${hdr_name}. 345764562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 345864562Sgshapiro removed if the config file version is greater than or equal 345964562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 346064562Sgshapiro input "token (1)" but does not match "token". 346164562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 346264562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 346364562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 346464562Sgshapiro Ericsson. 346564562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 346664562Sgshapiro messages with 8-bit text in headers. Problem noted by 346764562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 346864562Sgshapiro of Ericsson. 346964562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 347064562Sgshapiro modified database map file. Problem noted by Chris Adams 347164562Sgshapiro of Renaissance Internet Services. 347264562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 347364562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 347464562Sgshapiro queue up the message instead of bouncing it. 347564562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 347664562Sgshapiro standard does not provide any indication of what to do when 347764562Sgshapiro something other than 250 is received. Based on a patch 347864562Sgshapiro from Steve Schweinhart of America Online. 347964562Sgshapiro New option TrustedUser allows to specify a user who can own 348064562Sgshapiro important files instead of root. This requires HASFCHOWN. 348164562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 348264562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 348364562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 348464562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 348564562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 348664562Sgshapiro $? tests also whether the macro is non-null. 348764562Sgshapiro Print an error message if a mailer definition contains an invalid 348864562Sgshapiro equate name. 348964562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 349064562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 349164562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 349264562Sgshapiro mailer to return after sending all data to it. 349364562Sgshapiro Only free memory from the process list when adding a new process 349464562Sgshapiro into a previously filled slot. Previously, the memory was 349564562Sgshapiro freed at removal time. Since removal can happen in a 349664562Sgshapiro signal handler, this may leave the memory map in an 349764562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 349864562Sgshapiro David Cooley of Colby College. 349964562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 350064562Sgshapiro local users in the passwd file. The UserDB code has 350164562Sgshapiro already decided the message will be passed to another host 350264562Sgshapiro for processing. Fix from Tony Landells of Burdett 350364562Sgshapiro Buckeridge Young Limited. 350464562Sgshapiro Support LDAP authorization via either a file containing the 350564562Sgshapiro password or Kerberos V4 using the new map options 350664562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 350764562Sgshapiro distinguished_name is who to login as. The method can be 350864562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 350964562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 351064562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 351164562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 351264562Sgshapiro of Stanford University. 351364562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 351464562Sgshapiro deprecated and will be removed in a future version. 351564562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 351664562Sgshapiro and the map has the column delimiter set, it turns that 351764562Sgshapiro response into a delimiter separated string. The LDAP map 351864562Sgshapiro will traverse multiple entries as well. LDAP alias maps 351964562Sgshapiro automatically set the column delimiter to the comma. 352064562Sgshapiro Based on patch from Booker Bense of Stanford University and 352164562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 352264562Sgshapiro Support return of multiple values for a single LDAP lookup. The 352364562Sgshapiro values to be returned should be in a comma separated string. 352464562Sgshapiro For example, `-v "email,emailother"'. Patch from 352564562Sgshapiro Curtis W. Hillegas of Princeton University. 352664562Sgshapiro Allow the use of LDAP for alias maps. 352764562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 352864562Sgshapiro attributes found in the match will be returned. 352964562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 353064562Sgshapiro breaking up a single entry into multiple entries. This is 353164562Sgshapiro needed for LDAP alias file specifications to allow for 353264562Sgshapiro comma separated key and value strings. 353364562Sgshapiro Keep connections to LDAP server open instead of opening and closing 353464562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 353564562Sgshapiro connections such that multiple maps which use the same 353664562Sgshapiro host, port, bind DN, and authentication will only result in 353764562Sgshapiro a single connection to that host. 353864562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 353964562Sgshapiro Be more careful about checking for errors and freeing memory on 354064562Sgshapiro LDAP lookups. 354164562Sgshapiro Use asynchronous LDAP searches to save memory and network 354264562Sgshapiro resources. 354364562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 354464562Sgshapiro Increase portability to the Netscape LDAP libraries. 354564562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 354664562Sgshapiro replaced with the literal contents of the map lookup key -- 354764562Sgshapiro note that this means a lookup can be done using the LDAP 354864562Sgshapiro special characters. The new '%0' token can be used instead 354964562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 355064562Sgshapiro For example, if the LDAP map specification contains '-k 355164562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 355264562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 355364562Sgshapiro user attribute. Instead, if the LDAP map specification 355464562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 355564562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 355664562Sgshapiro with the name "*". 355764562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 355864562Sgshapiro more than one is returned, it is equivalent to no records 355964562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 356064562Sgshapiro alias dereference option; "-Z size" limits the number of 356164562Sgshapiro matches to return. 356264562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 356364562Sgshapiro LDAP maps. The value should only contain LDAP specific 356464562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 356564562Sgshapiro settings will be used for all LDAP maps unless they are 356664562Sgshapiro specified in the individual map specification ('K' 356764562Sgshapiro command). This option should be set before any LDAP maps 356864562Sgshapiro are defined. 356964562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 357064562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 357164562Sgshapiro Tech. 357264562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 357364562Sgshapiro particular, class entries get much smaller, which can be 357464562Sgshapiro important if you have large classes. 357564562Sgshapiro On network-related temporary failures, record the hostname which 357664562Sgshapiro gave error in the queued status message. Requested by 357764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 357864562Sgshapiro Add new F=% mailer flag to allow for a store and forward 357964562Sgshapiro configuration. Mailers which have this flag will not attempt 358071345Sgshapiro delivery on initial receipt of a message or on queue runs 358164562Sgshapiro unless the queued message is selected using one of the 358264562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 358364562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 358464562Sgshapiro New option ControlSocketName which, when set, creates a daemon 358564562Sgshapiro control socket. This socket allows an external program to 358664562Sgshapiro control and query status from the running sendmail daemon 358764562Sgshapiro via a named socket, similar to the ctlinnd interface to the 358864562Sgshapiro INN news server. Access to this interface is controlled by 358964562Sgshapiro the UNIX file permissions on the named socket on most UNIX 359064562Sgshapiro systems (see sendmail/README for more information). An 359164562Sgshapiro example control program is provided as contrib/smcontrol.pl. 359264562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 359364562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 359464562Sgshapiro number of processors online on the system (if that can be 359564562Sgshapiro determined). For single processor machines, this change 359664562Sgshapiro has no effect. 359764562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 359864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 359964562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 360064562Sgshapiro Motonori Nakamura of Kyoto University. 360164562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 360264562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 360364562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 360464562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 360564562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 360664562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 360764562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 360864562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 360964562Sgshapiro connection-based denial of service attacks. 361064562Sgshapiro Log basic information about authenticated connections at LogLevel 361164562Sgshapiro 10 or higher. 361264562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 361364562Sgshapiro information (from= syslog line). 361464562Sgshapiro Log the DSN code for each recipient if one is available as a new 361564562Sgshapiro equate (dsn=). 361664562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 3617120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 3618120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 3619120256Sgshapiro of the University of Illinois at Urbana-Champaign. 362064562Sgshapiro Detect temporary lookup failures in the host map if looking up a 362164562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 362264562Sgshapiro Finnish Meteorological Institute. 362364562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 362464562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 362564562Sgshapiro When a forward file points to an alias which runs a program, run 362664562Sgshapiro the program as the default user and the default group, not 362764562Sgshapiro the forward file user. This change also assures the 362864562Sgshapiro :include: directives in aliases are also processed using 362964562Sgshapiro the default user and group. Problem noted by Sergiu 363064562Sgshapiro Popovici of DNT Romania. 363164562Sgshapiro Prevent attempts to save a dead.letter file for a user with 363264562Sgshapiro no home directory (/no/such/directory). Problem noted by 363364562Sgshapiro Michael Brown of Finnigan FT/MS. 363464562Sgshapiro Include message delay and number of tries when logging that a 363564562Sgshapiro message has been completely delivered (LogLevel of 10 or 363664562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 363764562Sgshapiro Log the sender of a message even if none of the recipients were 363864562Sgshapiro accepted. If some of the recipients were rejected, it is 363964562Sgshapiro helpful to know the sender of the message. 364064562Sgshapiro Check the root directory (/) when checking a path for safety. 364164562Sgshapiro Problem noted by John Beck of Sun Microsystems. 364264562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 364364562Sgshapiro interactive and delivering to an alias which resolves to 364464562Sgshapiro multiple files. 364564562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 364664562Sgshapiro greater (see below); the help function doesn't print the 364764562Sgshapiro version of sendmail any longer, instead it is placed in 364864562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 364964562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 365064562Sgshapiro skipped and a version line (#vers) is introduced. The 365164562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 365264562Sgshapiro version is found, a warning is logged. The '#vers' 365364562Sgshapiro directive should be placed at the top of the help file. 365464562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 365564562Sgshapiro disk succeeded. Suggested by Nick Christenson. 365664562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 365764562Sgshapiro length before the attempt. 365864562Sgshapiro If a forward points to a filename for delivery, change to the 365964562Sgshapiro user's uid before checking permissions on the file. This 366064562Sgshapiro allows delivery to files on NFS mounted directories where 366164562Sgshapiro root is remapped to nobody. Problem noted by Harald 366264562Sgshapiro Daeubler of Universitaet Ulm. 366364562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 366464562Sgshapiro host status files, not all files. 366564562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 366664562Sgshapiro in the queue file for the message and set when delivery 366764562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 366864562Sgshapiro Wonderworks Inc. 366964562Sgshapiro Add support for storing information between rulesets using the new 367064562Sgshapiro macro map class. This can be used to store information 367164562Sgshapiro between queue runs as well using $={persistentMacros}. 367264562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 367364562Sgshapiro of Hannover. 367464562Sgshapiro New map class arith to allow for computations in rules. The 367564562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 367664562Sgshapiro as key. The two operands are specified as arguments; the 367764562Sgshapiro lookup returns the result of the computation. For example, 367864562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 367964562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 368064562Sgshapiro Add new syntax for header declarations which decide whether to 368164562Sgshapiro include the header based on a macro rather than a mailer 368264562Sgshapiro flag: 368364562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 368464562Sgshapiro This should be used along with $={persistentMacros}. 368564562Sgshapiro It can be used for adding headers to a message based on 368664562Sgshapiro the results of check_* and header check rulesets. 368764562Sgshapiro Allow new named config file rule check_eoh which is called after 368864562Sgshapiro all of the headers have been collected. The input to the 368964562Sgshapiro ruleset the number of headers and the size of all of the 369064562Sgshapiro headers in bytes separated by $|. This ruleset along with 369164562Sgshapiro the macro storage map can be used to correlate information 369264562Sgshapiro gathered between headers and to check for missing headers. 369364562Sgshapiro See cf/README or doc/op/op.ps for an example. 369464562Sgshapiro Change the default for the MeToo option to True to correspond 369564562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 369664562Sgshapiro option is deprecated and will be removed from a future 369764562Sgshapiro version. 369864562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 369964562Sgshapiro Change the sendmail binary default for SuperSafe to True. 370064562Sgshapiro Display ruleset names in debug and address test mode output 370164562Sgshapiro if referencing a named ruleset. 370264562Sgshapiro New mailer equate m= which will limit the number of messages 370364562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 370464562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 370564562Sgshapiro using it to sort. Now all the same domains are really run 370664562Sgshapiro through the queue together. If they have the same MX host, 370764562Sgshapiro then they will have a much better opportunity to use the 370864562Sgshapiro connection cache if available. This should be a reasonable 370964562Sgshapiro performance improvement. Patch from Randall Winchester of 371064562Sgshapiro the University of Maryland. 371164562Sgshapiro If a message is rejected by a header check ruleset, log who would 371264562Sgshapiro have received the message if it had not been rejected. 371364562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 371464562Sgshapiro queue immediately. No delivery attempt is made. 371564562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 371664562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 371764562Sgshapiro COMMANDS). 371864562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 371964562Sgshapiro but for outgoing connections. 372064562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 372164562Sgshapiro error messages and logging) and Modifiers, i.e. 372264562Sgshapiro a require authentication 372364562Sgshapiro b bind to interface through which mail has 372464562Sgshapiro been received 372564562Sgshapiro c perform hostname canonification 372664562Sgshapiro f require fully qualified hostname 372764562Sgshapiro h use name of interface for outgoing HELO 372864562Sgshapiro command 372964562Sgshapiro C don't perform hostname canonification 373064562Sgshapiro E disallow ETRN (see RFC 2476) 373164562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 373264562Sgshapiro h use name of interface for HELO command 373364562Sgshapiro The version number for queue files (qf) has been incremented to 4. 373464562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 373564562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 373664562Sgshapiro Institutes of Health. 373764562Sgshapiro If a mailer dies, print the status in decimal instead of octal 373864562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 373964562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 374064562Sgshapiro Move message priority from sender to recipient logging. Suggested by 374164562Sgshapiro Ulrich Windl of the Universitat Regensburg. 374264562Sgshapiro Add support for Berkeley DB 3.X. 374364562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 374464562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 374564562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 374664562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 374764562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 374864562Sgshapiro sub-options is set on the command line. Problem noted by 374964562Sgshapiro Graeme Hewson of Oracle. 375064562Sgshapiro Randomize equal preference MX records each time delivery is 375164562Sgshapiro attempted via a new connection to a host instead of once per 375264562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 375364562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 375464562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 375564562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 375664562Sgshapiro to hosts which have dynamically assigned names. 375764562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 375864562Sgshapiro the bounce for the same reason. If the body is not 8-bit 375964562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 376064562Sgshapiro not be included in the bounce. Problem noted by Valdis 376164562Sgshapiro Kletnieks of Virginia Tech. 376264562Sgshapiro The timeout for sending a message via SMTP has been changed from 376364562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 376464562Sgshapiro simply checks for progress on sending data every 5 minutes. 376564562Sgshapiro This will detect the inability to send information quicker 376664562Sgshapiro and reduce the number of processes simply waiting to 376764562Sgshapiro timeout. 376864562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 376964562Sgshapiro interface address structure when loading the system network 377064562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 377164562Sgshapiro Nanoteq. 377264562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 377364562Sgshapiro indicates the number of interfaces to read when probing 377464562Sgshapiro for hostnames and IP addresses for class w ($=w). The 377564562Sgshapiro default value is 512. Based on idea from Reinier 377664562Sgshapiro Bezuidenhout of Nanoteq. 377764562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 377864562Sgshapiro on load average. 377964562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 378064562Sgshapiro Northern Illinois University. 378164562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 378264562Sgshapiro envelope splitting has occurred. 378364562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 378464562Sgshapiro Luke Mewburn from RMIT University. 378564562Sgshapiro Add a "/quit" command to address test mode. 378664562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 378764562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 378864562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 378964562Sgshapiro Institute. 379064562Sgshapiro The contents of a class can now be copied to another class using 379164562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 379264562Sgshapiro the items in class $={Source} into the class $={Dest}. 379364562Sgshapiro Include original envelope's error transcript in bounces created for 379464562Sgshapiro split (owner-) envelopes to see the original errors when 379564562Sgshapiro the recipients were added. Based on fix from Motonori 379664562Sgshapiro Nakamura of Kyoto University. 379764562Sgshapiro Show reason for permanent delivery errors directly after the 379864562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 379964562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 380064562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 380164562Sgshapiro If the specification for the queue run interval (-q###) has a 380264562Sgshapiro syntax error, consider the error fatal and exit. 380364562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 380464562Sgshapiro noted by Motonori Nakamura of Kyoto University. 380564562Sgshapiro On operating systems which have setlogin(2), use it to set the 380664562Sgshapiro login name to the RunAsUserName when starting as a daemon. 380764562Sgshapiro This is for delivery to programs which use getlogin(). 380864562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 380964562Sgshapiro Differentiate between "command not implemented" and "command 381064562Sgshapiro unrecognized" in the SMTP dialogue. 381164562Sgshapiro Strip returns from forward and include files.

Problem noted by Juergen Georgi of RUS University 386664562Sgshapiro of Stuttgart and Kyle Tucker of Parexel International. 386764562Sgshapiro Prevent +detail information from interfering with local delivery to 386864562Sgshapiro multiple users in the same transaction (F=m). 386964562Sgshapiro Add H_FORCE flag for the X-Authentication-Warning: header, so it 387064562Sgshapiro will be added even if one already exists. Problem noted 387164562Sgshapiro by Michal Zalewski of Marchew Industries. 387264562Sgshapiro Stop processing SMTP commands if the SMTP connection is dropped. 387364562Sgshapiro This prevents a remote system from flooding the connection 387464562Sgshapiro with commands and then disconnecting. Previously, the 387564562Sgshapiro server would process all of the buffered commands. Problem 387664562Sgshapiro noted by Michal Zalewski of Marchew Industries. 387764562Sgshapiro Properly process user-supplied headers beginning with '?'. Problem 387864562Sgshapiro noted by Michal Zalewski of Marchew Industries. 387964562Sgshapiro If multiple header checks resolve to the $#error mailer, use the 388064562Sgshapiro last permanent (5XX) failure if any exist. Otherwise, use 388164562Sgshapiro the last temporary (4XX) failure. 388264562Sgshapiro RFC 1891 requires "hexchar" in a "xtext" to be upper case. Patch 388364562Sgshapiro from Ronald F.

Suggested by many. 388764562Sgshapiro Persistent host status data is not reloaded disk when current data 388864562Sgshapiro is available in the in-memory cache. Problem noted by Per 388964562Sgshapiro Hedeland of Ericsson. 389064562Sgshapiro mailq displays unprintable characters in addresses as their octal 389164562Sgshapiro representation and a leading backslash. This avoids problems 389264562Sgshapiro with "unprintable" characters. Problem noted by Michal 389364562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 389464562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 389564562Sgshapiro one character past the limit. This would cause subsequent 389664562Sgshapiro hops to break the line again. The '!' is now placed in 389764562Sgshapiro the last column of the limit if the line needs to be broken. 389864562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 389964562Sgshapiro from Per Hedeland of Ericsson. 390064562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 390164562Sgshapiro resolver will fall back to TCP. However, some 390264562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 390364562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 390464562Sgshapiro don't fail on ANY queries. 390564562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 390664562Sgshapiro address, do not send an empty postmaster notification DSN 390764562Sgshapiro to the postmaster.

Problem noted by Ezequiel H. Panepucci of 420964562Sgshapiro Yale University. 421064562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 421164562Sgshapiro be used for building. 421264562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 421364562Sgshapiro used for a fresh build. 421464562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 421564562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 421664562Sgshapiro ranlib. 421764562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 421864562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 421964562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 422064562Sgshapiro building of the man pages when defined. Suggested by Bryan 422164562Sgshapiro Costales. 422264562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 422364562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 422464562Sgshapiro installation of the sendmail helpfile and statistics file 422564562Sgshapiro respectively. Suggested by Bryan Costales. 422664562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 422764562Sgshapiro of Siemens Business Services. 422864562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 422964562Sgshapiro stdio library. The new buffered file I/O depends on the 423064562Sgshapiro Torek stdio library. This option can be either portable or 423164562Sgshapiro torek. 423264562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 423364562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 423464562Sgshapiro They should contain the C source files for the object files 423564562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 423664562Sgshapiro will be passed to the 'make depend' stage of compilation. 423764562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 423864562Sgshapiro in the sendmail distribution. Each has the form 423964562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 424064562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 424164562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 424264562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 424364562Sgshapiro building the distribution, but documentation on the changes 424464562Sgshapiro are in devtools/README. 424564562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 424664562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 424764562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 424864562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 424964562Sgshapiro new variable which identifies the root of the source 425064562Sgshapiro directories for all of the programs in the distribution. 425164562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 425264562Sgshapiro time. They can both still be overridden by setting the m4 425364562Sgshapiro macro. 425464562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 425564562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 425664562Sgshapiro build configurations, and places objects in obj.prefix.*/. 425764562Sgshapiro Complains as 'Build -f file' does for existing object 425864562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 425964562Sgshapiro Corporation. 426064562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 426164562Sgshapiro manual pages in the directory tree specified by 426264562Sgshapiro confMANROOTMAN. 426364562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 426464562Sgshapiro preformatted pages from the distribution. The new variable 426564562Sgshapiro confCOPY specifies the copying program. 426664562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 426764562Sgshapiro question.

Suggested by Neil Rickert of 429064562Sgshapiro Northern Illinois University. 429164562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 429264562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 429364562Sgshapiro the Finnish Meteorological Institute. 429464562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 429564562Sgshapiro MAILLOCK when compiling. Also requires linking with 429664562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 429764562Sgshapiro University. 429864562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 429964562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 430064562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 430164562Sgshapiro University. 430264562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 430364562Sgshapiro structure to the beginning of the program. This ensures that 430464562Sgshapiro the getservbyname() is done before any seteuid to a possibly 430564562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 430664562Sgshapiro on a Solaris system, this avoids syslog messages such as, 430764562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 430864562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 430964562Sgshapiro University. 431064562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 431164562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 431264562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 431364562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 431464562Sgshapiro characters (in LMTP mode), mail.local split the incoming 431564562Sgshapiro line up into 2046-character output lines (excluding the 431664562Sgshapiro newline). If an input line was 2047 characters long 431764562Sgshapiro (excluding CR-LF) and the last character was a '.', 431864562Sgshapiro mail.local saw it as the end of input, transfered it to the 431964562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 432064562Sgshapiro If the message was much longer, both sendmail and 432164562Sgshapiro mail.local would deadlock waiting for each other to read 432264562Sgshapiro what they have written. Problem noted by Peter Jeremy of 432364562Sgshapiro Alcatel Australia Limited. 432464562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 432564562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 432664562Sgshapiro Neil Rickert of Northern Illinois University. 432764562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 432864562Sgshapiro timeout to avoid starvation. 432964562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 433064562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 433164562Sgshapiro Infinite Monkeys & Co. 433264562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J.

Sites 481438032Speter which need the ability to override security can use the 481538032Speter DontBlameSendmail option. See the README file for more 481638032Speter information. 481738032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 481838032Speter if maps or alias files are in world writable directories. 481938032Speter This fixes the change added to 8.8.6 to prevent links in these 482038032Speter world writable directories. 482138032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 482238032Speter it is in a world writable directory. 482338032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 482438032Speter tty it may be able to push bytes back to the senders input. 482538032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 483438032Speter reverts back to the old behavior of using uid 1 and gid 1. 483538032Speter This is a security problem for Linux which has chosen that 483638032Speter uid and gid for user bin instead of daemon. If DefaultUser 483738032Speter is set in the configuration file, that value overrides this 483838032Speter default. 483990792Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-ID binaries 484038032Speter interfered with setting an alternate group id for the 484138032Speter RunAsUser option.

After this number is reached, sendmail 488538032Speter starts returning "452 Too many recipients" to all RCPT 488638032Speter commands. This can be used to limit the number of recipients 488738032Speter per envelope (in particular, to discourage use of the server 488838032Speter for spamming). Note: a better approach is to restrict 488938032Speter relaying entirely. 489038032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 489138032Speter to ldapx map and added timeout for ldap_open call to 489238032Speter avoid hanging sendmail in the event of hung LDAP servers. 489338032Speter Patch from Booker Bense of Stanford University. 489438032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 491738032Speter of Procter & Gamble. 491838032Speter New DontBlameSendmail option. This option allows administrators to 491938032Speter bypass some of sendmail's file security checks at the expense 492038032Speter of system security. This should only be used if you are 492138032Speter absolutely sure you know the consequences.

In particular, if you 495638032Speter have lots of virtual interfaces, this option will speed up 495738032Speter startup. However, unless you make other arrangements, mail 495838032Speter sent to those addresses will be bounced. 495938032Speter Automatically create alias databases if they don't exist and 496038032Speter AutoRebuildAliases is set. 496138032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 496238032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 496338032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 496438032Speter When determining the client host name ($&{client_name} macro), do 496538032Speter a forward (A) DNS lookup on the result of the PTR lookup 496638032Speter and compare results. If they differ or if the PTR lookup 496738032Speter fails, &{client_name} will contain the IP address 496864562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 496938032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 497038032Speter (i.e, it is like -ax for the temporary failure case, in 497138032Speter contrast to the success case). 497238032Speter New syntax to do limited checking of header syntax. A config line 497338032Speter of the form: 497438032Speter HHeader: $>Ruleset 497538032Speter causes the indicated Ruleset to be invoked on the Header 497638032Speter when read. This ruleset works like the check_* rulesets -- 497738032Speter that is, it can reject mail on the basis of the contents. 497838032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 497938032Speter from hiding their connection information in Received: 498038032Speter headers. 498138032Speter When SingleThreadDelivery is active, deliveries to locked hosts 498238032Speter are skipped. This will cause the delivering process to 498338032Speter try the next MX host or queue the message if no other MX 498438032Speter hosts are available. Suggested by Alexander Litvin. 498538032Speter The [FILE] mailer type now delivers to the file specified in the 498638032Speter A= equate of the mailer definition instead of $u. It also 498738032Speter obeys all of the F= mailer flags such as the MIME 498838032Speter 7/8 bit conversion flags. This is useful for defining 498938032Speter a mailer which delivers to the same file regardless of the 499064562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 499138032Speter Do not assume the identity of a remote connection is root@localhost 499238032Speter if the remote connection closes the socket before the 499338032Speter remote identity can be queried. 499438032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 499538032Speter Some mailers, including procmail, require that the real 499638032Speter uid is left unchanged by sendmail. Problem noted by Per 499738032Speter Hedeland of Ericsson. 499838032Speter No longer is the src/obj*/Makefile selected from a large list -- it 499938032Speter is now generated using the information in BuildTools/OS/ -- 500038032Speter some of the details are determined dynamically via 500138032Speter BuildTools/bin/configure.sh. 500238032Speter The other programs in the sendmail distribution -- mail.local, 500338032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 500438032Speter the new Build method which creates an operating system 500538032Speter specific Makefile using the information in BuildTools. 500638032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 500738032Speter a failure on one message won't affect future messages to the 500838032Speter same host). This is necessary if the remote host sends 500938032Speter a 451 error if the domain of the sender does not resolve 501038032Speter as is common in anti-spam configurations. Problem noted 501138032Speter by Mitchell Blank Jr of Exec-PC. 501238032Speter New "discard" mailer for check_* rulesets and header checking 501338032Speter rulesets. If one of the above rulesets resolves to the 501438032Speter $#discard mailer, the commands will be accepted but the 501538032Speter message will be completely discarded after it is accepting. 501638032Speter This means that even if only one of the recipients 501738032Speter resolves to the $#discard mailer, none of the recipients 501838032Speter will receive the mail. Suggested by Brian Kantor. 501938032Speter All but the last cloned envelope of a split envelope were queued 502038032Speter instead of being delivered.

Suggested by Scott 503738032Speter Gifford of The Internet Ramp. 503838032Speter Sendmail would get a segmentation fault if a mailer exited with an 503938032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 504038032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 504138032Speter Institute. 504238032Speter Separate snprintf/vsnprintf routines into separate file for use by 504338032Speter mail.local. 504438032Speter Allow multiple map lookups on right hand side, e.g., 504538032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 504638032Speter Christophe Wolfhugel of the Pasteur Institute. 504738032Speter Properly generate success DSN messages if requested for aliases 504838032Speter which have owner- aliases.

Patch from 512438032Speter Robert Harker of Harker Systems. 512538032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 512638032Speter directory for certain programs. 512738032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 512838032Speter local mail delivery. By the default, /usr/libexec/mail.local 512938032Speter is used. This is expected to be the mail.local shipped 513038032Speter with 8.9 which is LMTP capable. The path is based on the 513138032Speter new confEBINDIR m4 variable. 513238032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 513338032Speter FEATURE(smrsh). Note that this changes the default from 513438032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 513538032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 513638032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 513738032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 513838032Speter the user to setup different .forward files for 513938032Speter user+detail addressing. 514038032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 514138032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 514238032Speter DontProbeInterfaces, and DontBlameSendmail options. 514338032Speter CONFIG: by default do not allow relaying (that is, accepting mail 514438032Speter from outside your domain and sending it to another host 514538032Speter outside your domain). 514638032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 514738032Speter any site to any site. 514838032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 514938032Speter domain as defined by the 'm' class ($=m) to relay. 515038032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 515138032Speter the MX records of the host portion of an incoming recipient. 515238032Speter CONFIG: new FEATURE(access_db) which turns on the access database 515377349Sgshapiro feature. This database gives you the ability to allow 515438032Speter or refuse to accept mail from specified domains for 515538032Speter administrative reasons. By default, names that are listed 515638032Speter as "OK" in the access db are domain names, not host names. 515738032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 515838032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 515938032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 516038032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 516138032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 516238032Speter of FEATURE(access_db) and class 'R' to lookup individual 516338032Speter host names only. 516438032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 516538032Speter using % addressing is used, e.g. user%site@othersite, 516638032Speter and othersite is in class 'R', the check_rcpt ruleset 516738032Speter will strip @othersite and recheck user@site for relaying. 516838032Speter This feature changes that behavior. It should not be 516938032Speter needed for most installations. 517038032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 517138032Speter domain portion of the mail sender is a local host. This 517238032Speter should only be used if absolutely necessary as it opens 517338032Speter a window for spammers. Patch from Randall S. Winchester of 517438032Speter the University of Maryland. 517538032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 517638032Speter block incoming mail destined for certain recipient 517738032Speter usernames, hostnames, or addresses. 517838032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 517938032Speter refused if the host part of the argument to MAIL FROM: cannot 518038032Speter be located in the host name service (e.g., DNS). 518138032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 518238032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 518338032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 518438032Speter MAIL FROM: senders which do not include a domain. 518538032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 518638032Speter Realtime Blackhole List. You can specify the RBL name 518738032Speter server to contact by specifying it as an optional argument. 518838032Speter The default is rbl.maps.vix.com.

Users with local rulesets should place the 519338032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 519438032Speter returns $#OK, the message is accepted. If the ruleset 519538032Speter returns a mailer, the appropriate action is taken, else 519638032Speter the return of the ruleset is ignored. 519738032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 519838032Speter default to support file, :include:, and program deliveries. 519938032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 520038032Speter pick the proper default value.

Problem noted by Kari Hurtta of the Finnish 533438032Speter Meteorological Institute. 533538032Speter If /usr/tmp/dead.letter already existed, sendmail could not 533638032Speter add additional bounces to it. Problem noted by Thomas J. 533738032Speter Arseneault of SRI International. 533838032Speter If an SMTP mailer used a non-standard port number for the outgoing 533938032Speter connection, it would be displayed incorrectly in verbose mode. 534038032Speter Problem noted by John Kennedy of Cal State University, Chico. 534138032Speter Log the ETRN parameter specified by the client before altering them 534238032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 534338032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 534438032Speter User unknown with bogus delay= values. Change them to log 534538032Speter the same as compliant addresses. Problem noted by Kari E. 534638032Speter Hurtta of the Finnish Meteorological Institute. 534738032Speter Ignore the debug resolver option unless using sendmail debug trace 534838032Speter option for resolver. Problem noted by Greg Nichols of Wind 534938032Speter River Systems. 535038032Speter If SingleThreadDelivery was enabled and the remote server returned a 535138032Speter protocol error on the DATA command, the connection would be 535238032Speter closed but the persistent host status file would not be 535338032Speter unlocked so other sendmail processes could not deliver to 535438032Speter that host. Problem noted by Peter Wemm of DIALix. 535538032Speter If queueing up a message due to an expensive mailer, don't increment 535638032Speter the number of delivery attempts or set the last delivery 535738032Speter attempt time so the message will be delivered on the next 535838032Speter queue run regardless of MinQueueAge. Problem noted by 535938032Speter Brian J. Coan of the Institute for Global Communications. 536038032Speter Authentication warnings of "Processed from queue _directory_" and 536138032Speter "Processed by _username_ with -C _filename_" would be logged 536238032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 536338032Speter of the Finnish Meteorological Institute. 536438032Speter Use a better heuristic for detecting GDBM. 536538032Speter Log null connections on dropped connections. Problem noted by 536638032Speter Jon Lewis of Florida Digital Turnpike. 536738032Speter If class dbm maps are rebuilt, sendmail will now detect this and 536838032Speter reopen the map. Previously, they could give stale 536938032Speter results during a single message processing (but would 537038032Speter recover when the next message was received). Fix from 537138032Speter Joe Pruett of Q7 Enterprises. 537238032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 537338032Speter requests. Problem noted by Kari E. Hurtta of the 537438032Speter Finnish Meteorological Institute. 537538032Speter Do not send a bounce message back to the sender regarding bad 537638032Speter recipients if the SMTP connection is dropped before the 537738032Speter message is accepted. Problem noted by Kari E. Hurtta of the 537838032Speter Finnish Meteorological Institute. 537938032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 538038032Speter sendmail via a UNIX pipe. This will allow rulesets using 538138032Speter $&{client_name} to process without sending the string through 538238032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 538338032Speter A combination of deferred delivery mode, a double bounce situation, 538438032Speter and the inability to save a bounce message to 538538032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 538638032Speter to postmaster but not remove the offending envelope from the 538738032Speter queue causing it to create a new bounce message each time the 538838032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 538938032Speter Associates. 539038032Speter Remove newlines from hostname information returned via DNS. There are 539138032Speter no known security implications of newlines in hostnames as 539238032Speter sendmail filters newlines in all vital areas; however, this 539338032Speter could cause confusing error messages. 539438032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 539538032Speter rejected if any of the specified addresses were bad. This 539638032Speter behavior was modified to only reject the bad addresses and not 539738032Speter the entire message. Problem noted by Jozsef Hollosi of 539838032Speter SuperNet, Inc. 539938032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 540038032Speter Bryan Costales of InfoBeat, Inc. 540138032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 540238032Speter mailers. Problem noted by Kari E. Hurtta of the 540338032Speter Finnish Meteorological Institute. 540438032Speter An error in calculating the available space in the list of addresses 540538032Speter for logging deliveries could cause an address to be silently 540638032Speter dropped. 540738032Speter Include the initial user environment if sendmail is restarted via 540838032Speter a HUP signal. This will give room for the process title. 540938032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 541038032Speter Mail could be delivered without a body if the machine does not 541138032Speter support flock locking and runs out of processes during 541238032Speter delivery. Fix from Chuck Lever of the University of Michigan. 541338032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 541438032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 541538032Speter Institute. 541638032Speter Make sure non-rebuildable database maps are opened before the 541764562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 541838032Speter are needed for verifying the left hand side of the aliases. 541938032Speter Problem noted by Lloyd Parkes of Victoria University. 542038032Speter Make sure sender RFC822 source route addresses are alias expanded for 542138032Speter bounce messages. Problem noted by Juergen Georgi of 542238032Speter RUS University of Stuttgart. 542338032Speter Minor lint fixes. 542438032Speter Return a temporary error instead of a permanent error if an LDAP map 542538032Speter search returns an error. This will allow sequenced maps which 542638032Speter use other LDAP servers to be checked. Fix from Booker Bense 542738032Speter of Stanford University. 542838032Speter When automatically converting from quoted printable to 8bit text do 542938032Speter not pad bare linefeeds with a space. Problem noted by Theo 543038032Speter Nolte of the University of Technology Aachen, Germany. 543138032Speter Portability: 543238032Speter Non-standard C compilers may have had a problem compiling 543338032Speter conf.c due to a standard C external declaration of 543438032Speter setproctitle(). Problem noted by Ted Roberts of 543538032Speter Electronic Data Systems. 543638032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 543738032Speter Jagielski of jaguNET Access Services. 543838032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 543938032Speter Digital UNIX: Digital UNIX (and possibly others) moves 544038032Speter loader environment variables into the loader memory 544138032Speter area. If one of these environment variables (such as 544238032Speter LD_LIBRARY_PATH) was the last environment variable, 544338032Speter an invalid memory address would be used by the process 544438032Speter title routine causing memory corruption. Problem 544538032Speter noted by Sam Hartman of Mesa Internet Systems. 544638032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 544738032Speter chownsafe() to always return 0 even if the OS does 544838032Speter not permit file giveaways. Problem noted by 544938032Speter Yasutaka Sumi of The University of Tokyo. 545064562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 545138032Speter Gerald Rinske of Siemens Business Services VAS. 545238032Speter Linux: Pad process title with NULLs. Problem noted by 545338032Speter Jon Lewis of Florida Digital Turnpike. 545438032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 545538032Speter incorrect value for the number of interfaces. 545638032Speter Problem noted by Chris Loelke of JetStream Internet 545738032Speter Services. 545838032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 545938032Speter Rinske of Siemens Business Services VAS. 546038032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 546138032Speter used on a Solaris machine. Problem noted by 546238032Speter Stephen Ma of Jtec Pty Limited. 546338032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 546438032Speter Services VAS. 546538032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 546638032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 546738032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 546838032Speter Ericsson. 546938032Speter 547064562Sgshapiro8.8.7/8.8.7 1997/08/03 547138032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 547238032Speter an exclusive lock already set -- i.e., almost all systems 547338032Speter except 4.4-BSD derived systems), the initial attempt at 547438032Speter rebuilding aliases file if the database didn't already 547538032Speter exist would fail. Patch from Raymund Will of LST Software 547638032Speter GmbH. 547738032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 547838032Speter Problem noted by Fredrik J�nsson of the Royal Institute 547938032Speter of Technology, Stockholm. 548038032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 548138032Speter some environments could give "multiple definitions" for these 548238032Speter routines during compilation. If using TCP Wrappers, assume 548338032Speter that these routines are included as though they were in the 548438032Speter C library. Patch from Robert La Ferla. 548538032Speter When a NEWDB database map was rebuilt at the same time it was being 548638032Speter used by a queue run, the maps could be left locked for the 548738032Speter duration of the queue run, causing other processes to hang. 548838032Speter Problem noted by Kendall Libby of Shore.NET. 548938032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 549038032Speter mail was passed on without any recipient header. This could 549138032Speter cause problems downstream. Problem noted by Xander Jansen 549238032Speter of SURFnet ExpertiseCentrum. 549338032Speter Give error when GDBM is used with sendmail. GDBM's locking and 549438032Speter linking of the .dir and .pag files interferes with sendmail's 549538032Speter locking and security checks. Problems noted by Fyodor 549638032Speter Yarochkin of the Kyrgyz Republic FreeNet. 549738032Speter Don't fsync qf files if SuperSafe option is not set. 549838032Speter Avoid extra calls to gethostbyname for addresses for which a 549938032Speter gethostbyaddr found no value. Also, ignore any returns 550038032Speter from gethostbyaddr that look like a dotted quad. 550138032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 550238032Speter "may be forged", since at the network level we pretty much 550338032Speter have to assume that the information is good. 550438032Speter In some cases, errors during an SMTP session could leave files 550538032Speter open or locked. 550638032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 550790792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 550838032Speter errors during testing. 550938032Speter Errors in file locking of NEWDB maps had the incorrect file name 551038032Speter printed in the error message. 551138032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 551238032Speter missing parameter were issued, the EHLO behaved like a HELO. 551338032Speter Load limiting never kicked in for incoming SMTP transactions if the 551443730Speter DeliveryMode=background and any recipient was an alias or 551538032Speter had a .forward file. From Nik Conwell of Boston University. 551638032Speter On some non-Posix systems, the decision of whether chown(2) permits 551738032Speter file giveaway was undefined. From Tetsu Ushijima of the 551838032Speter Tokyo Institute of Technology. 551938032Speter Fix race condition that could cause the body of a message to be 552038032Speter lost (so only the header was delivered). This only occurs 552138032Speter on systems that do not use flock(2), and only when a queue 552238032Speter runner runs during a critical section in another message 552338032Speter delivery. Based on a patch from Steve Schweinhart of 552438032Speter Results Computing. 552538032Speter If a qf file was found in a mail queue directory that had a problem 552638032Speter (wrong ownership, bad format, etc.) and the file name was 552738032Speter exactly MAXQFNAME bytes long, then instead of being tried 552838032Speter once, it would be tried on every queue run. Problem noted 552938032Speter by Bryan Costales of Mercury Mail. 553038032Speter If the system supports an st_gen field in the status structure, 553138032Speter include it when reporting that a file has changed after open. 553238032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 553338032Speter This out to be checked as well as reported, since it is 553438032Speter theoretically possible for an attacker to remove a file after 553538032Speter it is opened and replace it with another file that has the 553638032Speter same i-number, but some filesystems (notably AFS) return 553738032Speter garbage in this field, and hence always look like the file 553838032Speter has changed. As a practical matter this is not a security 553938032Speter problem, since the files can be neither hard nor soft links, 554038032Speter and on no filesystem (that I am aware of) is it possible to 554138032Speter have two files on the same filesystem with the same i-number 554238032Speter simultaneously. 554338032Speter Delete the root Makefile from the distribution -- it is only for 554438032Speter use internally, and does not work at customer sites. 554538032Speter Fix botch that caused the second MAIL FROM: command in a single 554638032Speter transaction to clear the entire transaction. Problem 554738032Speter noted by John Kennedy of Cal State University, Chico. 554838032Speter Work properly on machines that have _PATH_VARTMP defined without 554938032Speter a trailing slash. (And a pox on vendors that decide to 555038032Speter ignore the established conventions!) Problem noted by 555138032Speter Gregory Neil Shapiro of WPI. 555238032Speter Internal changes to make it easier to add another protocol family 555338032Speter (intended for IPv6). Patches are from John Kennedy of 555438032Speter CSU Chico. 555538032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 555638032Speter an extra space at the beginning of some lines. Problem 555738032Speter noted by Charles Karney of Princeton University; fix based 555838032Speter on a patch from Christophe Wolfhugel. 555938032Speter Portability: 556038032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 556138032Speter with the _Sendmail_ book, 2nd edition. Note that 556238032Speter the book is actually wrong: _PATH_SENDMAILCF should 556338032Speter be used instead. 556438032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 556538032Speter of Argonne National Laboratory. 556638032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 556738032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 556838032Speter SunOS: Include <memory.h> to fix warning from util.c. From 556938032Speter James Aldridge of EUnet Ltd. 557038032Speter Solaris: Change STDIR (location of status file) to /etc/mail 557138032Speter in Makefiles. 557238032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 557338032Speter Makefiles. Use NEWDB on Linux instead. 557438032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 557538032Speter exists but behaves differently than other OSes. 557638032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 557738032Speter around the problem. Problem noted by Tom Moore of 557838032Speter NCR Corp. 557938032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 558038032Speter noted by Tom Smith of Digital Equipment Corp. 558138032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 558238032Speter noted by Tom Good of the Community Access Information 558338032Speter Resource Network 558438032Speter SCO 4.2: compile problems caused by a change in the type of 558538032Speter the "length" parameters passed to accept, getpeername, 558638032Speter getsockname, and getsockopt. Adds new compile flags 558738032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.

This makes it possible to create a root 563238032Speter owned file in an arbitrary directory by inserting the symlink 563338032Speter into a writable directory after the initial lstat(2) check 563438032Speter determined that the file did not exist. The only verified 563538032Speter example of a system having these odd semantics for O_EXCL 563638032Speter and symbolic links was HP-UX prior to version 9.07. Most 563738032Speter systems do not have the problem, since a exclusive create 563838032Speter of a file disallows symbolic links. Systems that have been 563938032Speter verified to NOT have the problem include AIX 3.x, *BSD, 564038032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 564138032Speter and Ultrix. This is a potential exposure on systems that 564238032Speter have this bug and which do not have a MAILER-DAEMON alias 564338032Speter pointing at a legitimate account, since this will cause old 564438032Speter mail to be dropped in /var/tmp/dead.letter. 564538032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 564638032Speter if maps or alias files are in world writable directories. 564738032Speter If your system has alias maps in writable directories, it 564838032Speter is potentially possible for an attacker to replace the .db 564938032Speter (or .dir and .pag) files by symbolic links pointing at 565038032Speter another database; this can be used either to expose 565138032Speter information (e.g., by pointing an alias file at /etc/spwd.db 565238032Speter and probing for accounts), or as a denial-of-service attack 565338032Speter (by trashing the password database). The fix disallows 565438032Speter symbolic links entirely when rebuilding alias files or on 565538032Speter maps that are in writable directories, and always warns on 565638032Speter writable directories; 8.9 will probably consider writable 565738032Speter directories to be fatal errors. This does not represent an 565838032Speter exposure on systems that have alias files in unwritable 565938032Speter system directories. 566038032Speter SECURITY: disallow .forward or :include: files that are links (hard 566138032Speter or soft) if the parent directory (or any directory in the 566238032Speter path) is writable by anyone other than the owner. This is 566338032Speter similar to the previous case for user files. This change 566438032Speter should not affect most systems, but is necessary to prevent 566538032Speter an attacker who can write the directory from pointing such 566638032Speter files at other files that are readable only by the owner. 566738032Speter SECURITY: Tighten safechown rules: many systems will say that they 566838032Speter have a safe (restricted to root) chown even on files that 566938032Speter are mounted from another system that allows owners to give 567038032Speter away files. The new rules are very strict, trusting file 567138032Speter ownership only in those few cases where the system has 567238032Speter been verified to be at least as paranoid as necessary. 567338032Speter However, it is possible to relax the rules to partially 567438032Speter trust the ownership if the directory path is not world or 567538032Speter group writable. This might allow someone who has a legitimate 567638032Speter :include: file (referenced directly from /etc/aliases) to 567738032Speter become another non-root user if the :include: file is in a 567838032Speter non-writable directory on an NFS-mounted filesystem where 567938032Speter the local system says that giveaway is denied but it is 568038032Speter actually permitted. I believe this to be a very small set 568138032Speter of cases. If in doubt, do not point :include: aliases at 568238032Speter NFS-mounted filesystems. 568338032Speter SECURITY: When setting a numeric group id using the RunAsUser option 568438032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 568538032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 568638032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 568738032Speter The user id was still set properly. Problem noted by Uli 568838032Speter Pralle of the Technical University of Berlin. 568938032Speter Save the initial gid set for use when checking for if the 569038032Speter PrivacyOptions=restrictmailq option is set. Problem reported 569138032Speter by Wolfgang Ley of DFN-CERT. 569238032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 569338032Speter failure on one message won't affect future messages to the 569438032Speter same host). 569538032Speter IP source route printing had an "off by one" error that would 569638032Speter affect any options that came after the route option. Patch 569738032Speter from Theo de Raadt. 569838032Speter The "Message is too large" error didn't successfully bounce the error 569938032Speter back to the sender. Problem reported by Stephen More of 570038032Speter PSI; patch from Gregory Neil Shapiro of WPI. 570138032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 570238032Speter of 5.1.3); it apparently gets used in multiple ways. 570338032Speter Suggested by John Myers of Portola Communications. 570438032Speter Fix possible extra null byte generated during collection if errors 570538032Speter occur at the beginning of the stream. Patch contributed by 570638032Speter Andrey A. Chernov and Gregory Neil Shapiro. 570738032Speter Code changes to avoid possible reentrant call of malloc/free within 570838032Speter a signal handler. Problem noted by John Beck of Sun 570938032Speter Microsystems. 571038032Speter Move map initialization to be earlier so that check_relay ruleset 571138032Speter will have the latest version of the map data. Problem noted 571238032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 571338032Speter If there are fatal errors during the collection phase (e.g., message 571438032Speter too large) don't send the bogus message. 571538032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 571638032Speter have errors and have owner- aliases. Problem noted by Michael 571738032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 571838032Speter Avoid null pointer dereference on illegal Boundary= parameters in 571938032Speter multipart/mixed Content-Type: header. Problem noted by 572038032Speter Richard Muirden of RMIT University. 572138032Speter Always print error messages during newaliases (-bi) even if the 572238032Speter ErrorMode is not set to "print". Fix from Gregory Neil 572338032Speter Shapiro. 572438032Speter Test mode could core dump if you did a /map lookup in an optional map 572538032Speter that could not be opened. Based on a fix from John Beck of 572638032Speter Sun Microsystems. 572738032Speter If DNS is misconfigured so that the last MX record tried points to 572838032Speter a host that does not have an A record, but other MX records 572938032Speter pointed to something reasonable, don't bounce the message 573038032Speter with a "host unknown" error. Note that this should really 573138032Speter be fixed in the zone file for the domain. Problem noted by 573238032Speter Joe Rhett of Navigist, Inc. 573338032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 573438032Speter the message as having been tried; otherwise the next queue 573538032Speter run will not realize that this is a second attempt and will 573638032Speter retry immediately. Problem noted by Bryan Costales of 573738032Speter Mercury Mail. 573838032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 573938032Speter will be run until the later setting of the clock is reached. 574038032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 574138032Speter Morgan Stanley. 574238032Speter If the load average rises above the cutoff threshold (above which 574338032Speter sendmail will not process the queue at all) during a queue 574438032Speter run, abort the queue run immediately. Problem noted by 574538032Speter Bryan Costales of Mercury Mail. 574638032Speter The variable queue processing algorithm (based on the message size, 574738032Speter number of recipients, message precedence, and job age) was 574838032Speter non-functional -- either the entire queue was processed or 574938032Speter none of the queue was processed. The updated algorithm 575038032Speter does no queue run if a single recipient zero size job will 575138032Speter not be run. 575238032Speter If there is a fatal ("panic") message that will cause sendmail to 575338032Speter die immediately, never hold the error message for future 575438032Speter printing. 575538032Speter Force ErrorMode=print in -bt mode so that all errors are printed 575638032Speter regardless of the setting of the ErrorMode option in the 575738032Speter configuration file. Patch from Gregory Neil Shapiro. 575838032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 575938032Speter routine available in one of the libraries. Use it in conf.h. 576038032Speter The -m (match only) flag now works on host class maps. 576138032Speter If class hash or btree maps are rebuilt, sendmail will now detect 576238032Speter this and reopen the map. Previously, they could give 576338032Speter erroneous results during a single message processing 576438032Speter (but would recover when the next message was received). 576538032Speter Don't delete zero length queue files when doing queue runs until the 576638032Speter files are at least ten minutes old. This avoids a potential 576738032Speter race condition: the creator creates the qf file, getting back 576838032Speter a file descriptor. The queue runner locks it and deletes it 576938032Speter because it is zero length. The creator then writes the 577038032Speter descriptor that is now for a disconnected file, and the 577138032Speter job goes away. Based on a suggestion by Bryan Costales. 577238032Speter When determining the "validated" host name ($_ macro), do a forward 577338032Speter (A) DNS lookup on the result of the PTR lookup and compare 577438032Speter results. If they differ or if the PTR lookup fails, tag the 577538032Speter address as "may be forged". 577638032Speter Log null connections (i.e., hosts that connect but do not do any 577738032Speter substantive activity on the connection before disconnecting; 577838032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 577938032Speter Always permit "writes" to /dev/null regardless of the link count. 578038032Speter This is safe because /dev/null is special cased, and no open 578138032Speter or write is ever actually attempted. Patch from Villy Kruse 578238032Speter of TwinCom. 578338032Speter If a message cannot be sent because of a 552 (exceeded storage 578438032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 578538032Speter was given, don't return the body in the bounce, since there 578638032Speter is a very good chance that the message will double-bounce. 578738032Speter Fix possible line truncation if a quoted-printable had an =00 escape 578838032Speter in the body. Problem noted by Charles Karney of the Princeton 578938032Speter Plasma Physics Laboratory. 579038032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 579138032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 579238032Speter Institute. 579338032Speter The MaxDaemonChildren option wasn't applying to queue runs as 579438032Speter documented. Note that this increases the potential denial 579538032Speter of service problems with this option: an attacker can 579638032Speter connect many times, and thereby lock out queue runs as well 579738032Speter as incoming connections. If you use this option, you should 579838032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 579938032Speter to avoid this attack. Failure to limit noted by Matthew 580038032Speter Dillon of BEST Internet Communications. 580138032Speter Always give a message in newaliases if alias files cannot be 580238032Speter opened instead of failing silently. Suggested by Gregory 580338032Speter Neil Shapiro. This change makes the code match the O'Reilly 580438032Speter book (2nd edition). 580538032Speter Some older versions of the resolver could return with h_errno == -1 580638032Speter if no name server could be reached, causing mail to bounce 580738032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 580838032Speter John Beck of SunSoft. 580938032Speter If a :include: file is owned by a user that does not have an entry 581038032Speter in the passwd file, sendmail could dereference a null pointer. 581138032Speter Problem noted by Satish Mynam of Sun Microsystems. 581238032Speter Take precautions to make sure that the SMTP protocol cannot get out 581338032Speter of sync if (for example) an alias file cannot be opened. 581438032Speter Fix a possible race condition that can cause a SIGALRM to come in 581538032Speter immediately after a SIGHUP, causing the new sendmail to die. 581638032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 581738032Speter from Villy Kruse of TwinCom. 581838032Speter Ignore improperly formatted SMTP reply codes. Previously these were 581938032Speter partially processed, which could cause confusing error 582038032Speter returns. 582138032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 582238032Speter on some architectures. 582338032Speter Portability: 582438032Speter A/UX: from Jim Jagielski of NASA/GSFC. 582538032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 582638032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 582738032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 582838032Speter defined. Problem reported by A Sun of the University 582938032Speter of Washington. 583038032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 583138032Speter the system rather than guessing at compile time. 583238032Speter Patch contributed by John Beck of Sun Microsystems. 583338032Speter Intel Paragon: from Wendy Lin of Purdue University. 583438032Speter GNU Hurd: from Miles Bader of the GNU project. 583538032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 583638032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 583738032Speter Unfortunately releasing them opens a race condition, 583838032Speter but there appears to be no fix for this. Patch from 583938032Speter Gregory Neil Shapiro. 584038032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 584138032Speter Solaris: a bug in strcasecmp caused characters with the 584238032Speter high order bit set to apparently randomly match 584338032Speter letters -- for example, $| (0233) matches "i" and "I". 584438032Speter Problem noted by John Gregson of the University of 584538032Speter Cambridge. 584638032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 584738032Speter Kari Hurtta. 584838032Speter IRIX 6.x: Create Makefiles for systems that claim to be 584938032Speter IRIX64 but are 6.2 or higher (so use the regular 585038032Speter IRIX Makefile). 585138032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 585238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 585338032Speter CONFIG: Some canonification was still done for UUCP-like addresses 585438032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 585538032Speter Brian Candler. 585638032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 585738032Speter local names as local. Problem noted by Jeff Polk of BSDI; 585838032Speter fix provided by Gregory Neil Shapiro. 585938032Speter CONFIG: The "local:user" syntax entries in mailertables and other 586038032Speter "mailer:user" syntax locations returned an incorrect value 586138032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 586238032Speter CONFIG: Retain "+detail" information when forwarding mail to a 586338032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 586438032Speter Guenther of Gustavus Adolphus College. 586538032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 586638032Speter rules are the same as for aliasing. Based on a patch from 586738032Speter Gregory Neil Shapiro. 586838032Speter CONFIG: Break up parsing rules into several pieces; this should 586938032Speter have no functional change in this release, but makes it 587038032Speter possible to have better anti-spam rulesets in the future. 587138032Speter CONFIG: Disallow double dots in host names to avoid having the 587238032Speter HostStatusDirectory store status under the wrong name. 587338032Speter In some cases this can be used as a denial-of-service attack. 587438032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 587538032Speter Gregory Neil Shapiro. 587638032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 587738032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 587838032Speter don't include From_, and convert to 8-bit). Suggestions 587938032Speter from Kimmo Suominen and Roderick Schertler. 588064562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 588138032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 588238032Speter was specified, even when it wasn't. 588338032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 588438032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 588538032Speter "slip in" a symbolic link between the lstat(2) call and the 588638032Speter exclusive open. This is only a problem on System V derived 588738032Speter systems that allow an exclusive create on files that are 588838032Speter symbolic links pointing nowhere. 588938032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 589038032Speter not reset back to root, which on some systems would cause 589138032Speter later mailboxes to fail. Also, any partial message would 589238032Speter not be truncated, which could result in repeated deliveries. 589338032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 589438032Speter developers). 589538032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 589638032Speter change to the sendmail map code was made in 8.8.3. Problem 589738032Speter noted by Gregory Neil Shapiro. 589838032Speter MAKEMAP: Give warnings on file problems such as map files that are 589990792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 590038032Speter often run as root and hence has the potential for the same 590138032Speter sorts of problems as alias rebuilds. 590238032Speter MAKEMAP: Change compilation so that it will link properly on 590338032Speter NEXTSTEP. 590438032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 590538032Speter Accept an optional list of arguments following the server 590638032Speter name for the ETRN arguments to use (instead of $=w).

This 591038032Speter Perl script converts GECOS information in the /etc/passwd 591138032Speter file into aliases, allowing for faster access to full name 591238032Speter lookups; it is also clever about adding aliases (to root) 591338032Speter for system accounts. 591438032Speter NEW FILES: 591538032Speter src/safefile.c 591638032Speter cf/ostype/gnuhurd.m4 591738032Speter cf/ostype/irix6.m4 591838032Speter contrib/passwd-to-alias.pl 591938032Speter src/Makefiles/Makefile.IRIX64.6.1 592038032Speter src/Makefiles/Makefile.IRIX64.6.x 592138032Speter RENAMED FILES: 592238032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 592338032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 592438032Speter 592564562Sgshapiro8.8.5/8.8.5 1997/01/21 592638032Speter SECURITY: Clear out group list during startup. Without this, sendmail 592738032Speter will continue to run with the group permissions of the caller, 592838032Speter even if RunAsUser is specified. 592938032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 593038032Speter to any known attack, but it's best to be conservative. 593138032Speter Suggested by Peter Wemm of DIALix. 593238032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 593338032Speter security implications. Patch from Alex Garthwaite of the 593438032Speter University of Pennsylvania. 593538032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 593638032Speter would truncate the address after "Full". Although the -f 593738032Speter syntax is incorrect (since it is in the envelope, it 593838032Speter shouldn't have comments and full names), the failure mode 593938032Speter was unnecessarily awful. 594038032Speter Fix a possible null pointer dereference when converting 8-bit data 594138032Speter to a 7-bit format. Problem noted by Jim Hutchins of 594238032Speter Sandia National Labs and David James of British Telecom. 594338032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 594438032Speter runs. Although this really shouldn't be used (F=9 is for 594538032Speter final delivery only, and using it on an SMTP mailer makes 594638032Speter it possible for a message to be converted from 8->7->8->7 594738032Speter bits several times), it shouldn't have failed with a syserr. 594838032Speter Problem noted by Eric Hagberg of Morgan Stanley. 594938032Speter _Really_ fix the multiple :maildrop code in the user database 595038032Speter module. Patch from Roy Mongiovi of Georgia Tech. 595138032Speter Let F lines in the configuration file actually read root-only 595238032Speter files if the configuration file is safe. Based on a 595338032Speter patch from Keith Reynolds of SCO. 595438032Speter ETRN followed by QUIT would hold the connection open until the queue 595538032Speter run completed. Problem noted by Truck Lewis of TDK 595638032Speter Semiconductor Corp. 595738032Speter It turns out that despite the documentation, the TCP wrappers library 595838032Speter does _not_ log rejected connections. Do the logging ourselves. 595938032Speter Problem noted by Fletcher Mattox of the University of Texas 596038032Speter at Austin. 596138032Speter If sendmail finds a qf file in its queue directory that is an unknown 596238032Speter version (e.g., when backing out to an old version), the 596338032Speter error is reported on every queue run. Change it to only 596438032Speter give the error once (and rename the qf => Qf). Patch from 596538032Speter William A. Gianopoulos of Raytheon Company. 596638032Speter Start a new session when doing background delivery; currently it 596738032Speter ignored signals but didn't start a new signal, that caused 596838032Speter some problems if a background process tried to send mail 596938032Speter under certain circumstances. Problem noted by Eric Hagberg 597038032Speter of Morgan Stanley; fix from Kari Hurtta. 597138032Speter Simplify test for skipping a queue run to just check if the current 597238032Speter load average is >= the queueing load average. Previously 597338032Speter the check factored in some other parameters that caused it 597438032Speter to essentially never skip the queue run. Patch from Bryan 597538032Speter Costales. 597638032Speter If the SMTP server is running in "nullserver" mode (that is, it is 597738032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 597838032Speter (25) commands; this helps prevent a bad guy from putting 597938032Speter you into a tight loop as a denial-of-service attack. Based 598038032Speter on an e-mail conversation with Brad Knowles of AOL. 598138032Speter Slow down when too many "light weight" commands have been issued; 598238032Speter this helps prevent a class of denial-of-service attacks. 598338032Speter The current values and defaults are: 598438032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 598538032Speter MAXHELOCOMMANDS 3 HELO, EHLO 598638032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 598738032Speter MAXETRNCOMMANDS 8 ETRN 598838032Speter These will probably be configurable in a future release. 598938032Speter On systems that have uid_t typedefed to be an unsigned short, programs 599038032Speter that had the F=S flag and no U= equate would be invoked with 599138032Speter the real uid set to 65535 rather than being left unchanged. 599238032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 599338032Speter by Steve Hubert of the University of Washington, Seattle. 599438032Speter Mail that was Quoted-Printable encoded and had a soft line break on 599538032Speter the last line (i.e., an incomplete continuation) had the last 599638032Speter line dropped. Since this appears to be illegal it isn't 599738032Speter clear what to do with it, but flushing the last line seems 599838032Speter to be a better "fail soft" approach. Based on a patch from 599938032Speter Eric Hagberg. 600038032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 600138032Speter bogus HELO command still causes the "Polite people say HELO 600238032Speter first" error message. Problem pointed out by Chris Thomas 600338032Speter of UCLA; patch from John Beck of SunSoft. 600438032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 600571345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 600671345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 600771345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 600838032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 600938032Speter in a DATA transaction to be sticky; these can occur because 601038032Speter a message is too large, and smaller messages should still go 601138032Speter through. Problem noted by Matt Dillon of Best Internet 601238032Speter Communications. 601338032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 601438032Speter had been successfully delivered to the envelope sender. 601538032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 601638032Speter Gregory Neil Shapiro of WPI. 601738032Speter Give better diagnostics on long alias lines. Based on code contributed 601838032Speter by Patrick Gosling of the University of Cambridge. 601938032Speter Increase the number of virtual interfaces that will be probed for 602038032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 602138032Speter PORTABILITY: 602238032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 602338032Speter Toshiaki Nomura of Fujitsu Limited. 602438032Speter SunOS with LDAP support: compile problems with struct timeval. 602538032Speter Patch from Nick Cuccia of TCSI Corporation. 602638032Speter SCO: from Keith Reynolds of SCO. 602738032Speter Solaris: kstat load average computation wasn't being used. 602838032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 602938032Speter (Moscow). 603038032Speter OpenBSD: from Jason Downs of teeny.org. 603138032Speter Altos System V: from Tim Rice. 603238032Speter Solaris 2.5: from Alan Perry of SunSoft. 603338032Speter Solaris 2.6: from John Beck of SunSoft. 603438032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 603538032Speter of Pratt & Whitney <miorelli@pweh.com>. 603638032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 603738032Speter _just_right_ yet. Tweak it again. I'll omit the names 603838032Speter of the "contributors" (quantity two) in this one case. 603938032Speter As of now, NO MORE DISCUSSION about the syntax of the 604038032Speter Received: line. 604138032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 604238032Speter it never inserts that class into the output file. Fix it 604338032Speter so it will honor EXPOSED_USER but will _not_ include root 604438032Speter automatically in this class. Problem noted by Ronan KERYELL 604538032Speter of Centre de Recherche en Informatique de l'�cole Nationale 604638032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 604738032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 604838032Speter such as LUSER_RELAY. This change permits the following 604938032Speter syntaxes: ``local:'' will send to the same user on the 605038032Speter local machine (e.g., in a mailertable entry for "host", 605138032Speter ``local:'' will cause an address addressed to user@host to 605238032Speter go to user on the local machone). ``local:user'' will send 605338032Speter to the named user on the local machine. ``local:user@host'' 605438032Speter is equivalent to ``local:user'' (the host is ignored). In 605538032Speter all cases, the original user@host is passed in $@ (i.e., the 605638032Speter detail information). Inspired by a report from Michael Fuhr. 605738032Speter CONFIG: Strip quotes from the first word of an "error:" host 605838032Speter indication. This lets you set (for example) the LUSER_RELAY 605938032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 606038032Speter of the \" so that the resulting string is properly quoted. 606138032Speter Problem noted by Gregory Neil Shapiro of WPI. 606238032Speter OP.ME: documentation was inconsistent about whether sendmail did a 606338032Speter NOOP or a RSET to probe the connection (it does a RSET). 606438032Speter Inconsistency noted by Deeran Peethamparam. 606538032Speter OP.ME: insert additional blank pages so it will print properly on 606638032Speter a duplex printer. From Matthew Black of Cal State University, 606738032Speter Long Beach. 606838032Speter 606964562Sgshapiro8.8.4/8.8.4 1996/12/02 607038032Speter SECURITY: under some circumstances, an attacker could get additional 607138032Speter permissions by hard linking to files that were group 607238032Speter writable by the attacker. The solution is to disallow any 607338032Speter files that have hard links -- this will affect .forward, 607438032Speter :include:, and output files. Problem noted by Terry 607538032Speter Kyriacopoulos of Interlog Internet Services. As a 607638032Speter workaround, set UnsafeGroupWrites -- always a good idea. 607738032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 607838032Speter is, it is possible to do a denial-of-service attack on 607938032Speter MX hosts that rely on the use of the null MX list. There 608038032Speter is no danger if you have this option turned off (the default). 608138032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 608238032Speter unsafe. I know of no specific attack against this, although 608338032Speter a denial-of-service attack is probably possible, but in theory 608438032Speter you should not be able to safely tweak anything that affects 608538032Speter the permissions that are used when mail is delivered. 608638032Speter Purgestat could go into an infinite loop if one of the host status 608738032Speter directories somehow became empty. Problem noted by Roy 608838032Speter Mongiovi of Georgia Tech. 608938032Speter Processes got "lost" when counting children due to a race condition. 609038032Speter This caused "proc_list_probe: lost pid" messages to be logged. 609138032Speter Problem noted by several people. 609238032Speter On systems with System V SIGCLD child signal semantics (notably AIX 609338032Speter and HP-UX), mail transactions would print the message "451 609438032Speter SMTP-MAIL: lost child: No child processes". Problem noted 609538032Speter by several people. 609638032Speter Miscellaneous compiler warnings on picky compilers (or when setting 609738032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 609838032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 609938032Speter not be persistent between runs, since they are based on the 610038032Speter message rather than the host. Problem noted by Matt Dillon 610138032Speter of Best Internet Communications. 610238032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 610338032Speter of NCR (a.k.a., AT&T Global Information Solutions). 610438032Speter Avoid the possibility of having a child daemon run to completion 610538032Speter (including closing the SMTP socket) before the parent has 610638032Speter had a chance to close the socket; this can cause the parent 610738032Speter to hang for a long time waiting for the socket to drain. 610838032Speter Patch from Don Lewis of TDK Semiconductor. 610938032Speter If the fork() failed in a queue run, the queue runners would not be 611038032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 611138032Speter Some error conditions in ETRN could cause output without an SMTP 611238032Speter status code. Problem noted by Don Lewis. 611338032Speter Multiple :maildrop addresses in the user database didn't work properly. 611438032Speter Patch from Roy Mongiovi of Georgia Tech. 611538032Speter Add ".db" automatically onto any user database spec that does not 611638032Speter already have it; this is for consistency with makemap, the 611738032Speter K line, and the documentation. Inconsistency pointed out 611838032Speter by Roy Mongiovi. 611938032Speter Allow sendmail to be properly called in nohup mode. Patch from 612038032Speter Kyle Jones of UUNET. 612138032Speter Change ETRN to ignore but still update host status files; previously 612238032Speter it would ignore them and not save the updated status, which 612338032Speter caused stale information to be maintained. Based on a patch 612438032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 612538032Speter ETRN ignore the MinQueueAge option. 612638032Speter Patch long term host status to recover more gracefully from an empty 612738032Speter host status file condition. Patch from NAKAMURA Motonori 612838032Speter of Kyoto University. 612938032Speter Several patches to signal handling code to fix potential race 613038032Speter conditions from Don Lewis. 613138032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 613238032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 613338032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 613438032Speter compile flag; use NETINET instead. Solution based on a 613538032Speter patch from Bryan Costales. 613638032Speter PORTABILITY FIXES: 613738032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 613838032Speter /etc/security/passwd file when called as root. This 613938032Speter is very slow on some systems. To speed it up, use the 614038032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 614138032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 614238032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 614338032Speter Glicker of Burrelle's Information Service. 614438032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 614538032Speter from Makoto MATSUSHITA of Osaka University. 614638032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 614738032Speter Leeds University and SASABE Tetsuro of the University 614838032Speter of Tokyo. 614938032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 615038032Speter Services, Inc. 615138032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 615238032Speter I believe this to have only been a problem if you 615338032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 615438032Speter to stick with /etc/sendmail.cf as your One True Path. 615538032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 615638032Speter Martin Laubach of the Technischen Universit�t Wien. 615738032Speter CONFIG: change default Received: line to be multiple lines rather 615838032Speter than one long one. By popular demand. 615938032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 616038032Speter from Jerome Berkman of U.C. Berkeley. 616138032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 616238032Speter to take a very long time. Problem noted by Yoshiro YONEYA 616338032Speter of NTT Software Corporation. 616438032Speter CONTRIB: add etrn.pl, contributed by John Beck. 616538032Speter NEW FILES: 616638032Speter contrib/etrn.pl 616738032Speter 616864562Sgshapiro8.8.3/8.8.3 1996/11/17 616938032Speter SECURITY: it was possible to get a root shell by lying to sendmail 617038032Speter about argv[0] and then sending it a signal. Problem noted 617138032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 617238032Speter best-of-security list. 617338032Speter Log sendmail binary version number in "Warning: .cf version level 617438032Speter (%d) exceeds program functionality (%d) message" -- this 617538032Speter should make it clearer to people that they are running 617638032Speter the wrong binary. 617738032Speter Fix a problem that occurs when you open an SMTP connection and then 617838032Speter do one or more ETRN commands followed by a MAIL command; at 617938032Speter the end of the DATA phase sendmail would incorrectly report 618038032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 618138032Speter noted by Eric Bishop of Virginia Tech. 618238032Speter When doing text-based host canonification (typically /etc/hosts 618338032Speter lookup), a null host name would match any /etc/hosts entry 618438032Speter with space at the end of the line. Problem noted by Steve 618538032Speter Hubert of the University of Washington, Seattle. 618638032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 618738032Speter Problem reported by Tom Smith of Digital Equipment Corp. 618838032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 618938032Speter size PACKETSZ (512) is not sufficient for some nameserver 619038032Speter answers containing very many resource records. The resolver 619138032Speter may also switch to TCP and retry if it detects UDP packet 619238032Speter overflow. Also, allow for the fact that the resolver 619338032Speter routines res_query and res_search return the size of the 619438032Speter *un*truncated answer in case the supplied answer buffer it 619538032Speter not big enough to accommodate the entire answer. Patch from 619638032Speter Eric Wassenaar. 619738032Speter Improvements to MaxDaemonChildren code. If you think you have too 619838032Speter many children, probe the ones you have to verify that they 619938032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 620038032Speter Also, do this probe before growing the vector of children 620138032Speter pids; this previously caused the vector to grow indefinitely 620238032Speter due to a race condition. Problem reported by Kyle Jones of 620338032Speter UUNET. 620438032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 620538032Speter O_EXLOCK to zero; this fools the map compilation code into 620638032Speter thinking that it can avoid race conditions by locking on open. 620738032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 620838032Speter Leif Erlingsson of Data Lege. 620938032Speter Always call res_init() on startup (if compiled in, of course) to 621038032Speter allow the sendmail.cf file to tweak resolver flags; without 621138032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 621238032Speter Andrew Sun of Merrill Lynch. 621338032Speter Improvements to host status printing code. Suggested by Steve Hubert 621438032Speter of the University of Washington, Seattle. 621538032Speter Change MinQueueAge option processing to do the check for the job age 621638032Speter when reading the queue file, rather than at the end; this 621738032Speter avoids parsing the addresses, which can do DNS lookups. 621838032Speter Problem noted by John Beck of InReference, Inc. 621938032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 622038032Speter properly escaped. Problem noted by Peter Nilsson of the 622138032Speter University of Linkoping. 622238032Speter In some cases, sendmail would retain root permissions during queue 622338032Speter runs even if RunAsUser was set. Problem noted by Mark 622438032Speter Thomas of Mark G. Thomas Consulting. 622538032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 622638032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 622738032Speter the envelope, and the receiving SMTP server speaks DSN, then 622838032Speter the DSN would be both generated locally and propagated to the 622938032Speter other end. 623038032Speter The U= mailer field didn't correctly extract the group id if the 623138032Speter user id was numeric. Problem noted by Kenneth Herron of 623238032Speter MCI Telecommunications Communications. 623338032Speter If a message exceeded the fixed maximum size on input, the body of 623438032Speter the message was included in the bounce. Note that this did 623538032Speter not occur if it exceeded the maximum _output_ size. Problem 623638032Speter reported by Kyle Jones of UUNET. 623738032Speter PORTABILITY FIXES: 623838032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 623938032Speter AIX4 defines to use seteuid(2) instead, which 624038032Speter works on 4.1 as well as 4.2. Problem noted by 624138032Speter H�kan Lindholm of interAF, Sweden. 624238032Speter AIX4: use tzname[] vector to determine time zone name. 624338032Speter Patch from NAKAMURA Motonori of Kyoto University. 624438032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 624538032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 624638032Speter Solaris: kstat(3k) support for retrieving the load average. 624738032Speter This adds the LA_KSTAT definition for LA_TYPE. 624838032Speter The outline of the implementation was contributed 624938032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 625038032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 625138032Speter declaration of struct rusage at the top of conf.h; 625238032Speter change it to only be included if you are using gcc, 625338032Speter which is apparently the only compiler that requires 625438032Speter it in the first place. Problem noted by Jeff 625538032Speter Earickson of Colby College. 625638032Speter IRIX: don't default to using gcc. IRIX is a civilized 625738032Speter operating system that comes with a decent compiler 625838032Speter by default. Problem noted by Barry Bouwsma and 625938032Speter Kari Hurtta. 626038032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 626138032Speter consistency with other local mailers. Inconsistency 626238032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 626338032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 626438032Speter overhead) as part of the bestmx_is_local feature, the 626538032Speter domain part was dropped from the name. Patch from Steve 626638032Speter Hubert of the University of Washington, Seattle. 626738032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 626838032Speter end up being translated to the null host name, which would 626938032Speter return any entry in /etc/hosts that had a space at the end 627038032Speter of the line. Problem noted by Steve Hubert of the 627138032Speter University of Washington, Seattle. 627238032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 627338032Speter Polytechnic Institute. 627438032Speter MAKEMAP: tweak hash and btree parameters for better performance. 627538032Speter Patch from Matt Dillon of Best Internet Communications. 627638032Speter NEW FILES: 627738032Speter src/Makefiles/Makefile.Linux.ppc 627838032Speter cf/ostype/aix4.m4 627938032Speter cf/ostype/mklinux.m4 628038032Speter 628164562Sgshapiro8.8.2/8.8.2 1996/10/18 628238032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 628338032Speter changed the code but didn't fix the problem. 628438032Speter PORTABILITY FIXES: 628538032Speter Solaris: Don't use the system getusershell(3); it can 628638032Speter apparently corrupt the heap in some circumstances. 628738032Speter Problem found by Ken Pizzini of Spry, Inc. 628838032Speter OP.ME: document several mailer flags that were accidentally omitted 628938032Speter from this document.

Problem noted 629538032Speter by Dan Bernstein of the University of Illinois at Chicago. 629638032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 629738032Speter message could overflow a buffer if it was converted back 629838032Speter to 8 bits. This caused core dumps and has the potential 629938032Speter for a remote attack. Problem first noted by Gregory Shapiro 630038032Speter of WPI. 630138032Speter Avoid duplicate deliveries of error messages on systems that don't 630238032Speter have flock(2) support. Patch from Motonori Nakamura of 630338032Speter Kyoto University. 630438032Speter Ignore null FallBackMX (V) options. If this option is null (as 630538032Speter opposed to undefined) it can cause "null signature" syserrs 630638032Speter on illegal host names. 630738032Speter If a Base64 encoded text/plain message has no trailing newline in 630838032Speter the encoded text, conversion back to 8 bits will drop the 630938032Speter final line. Problem noted by Pierre David. 631038032Speter If running with a RunAsUser, sendmail would give bogus "cannot 631138032Speter setuid" (or seteuid, or setreuid) messages on some systems. 631238032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 631338032Speter Always print error messages in -bv mode -- previously, -bv would 631438032Speter be absolutely silent on errors if the error mode was sent 631538032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 631638032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 631738032Speter term host status. This is necessary because it is common 631838032Speter to do this when you know a host has just come back up. 631938032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 632038032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 632138032Speter University of Leicester. 632238032Speter If a service (such as NIS) is specified as the last entry in the 632338032Speter service switch, but that service is not compiled in, sendmail 632438032Speter would return a temporary failure when an entry was not found 632538032Speter in the map. This caused the message to be queued instead of 632638032Speter bouncing immediately. Problem noted by Harry Edmon of the 632738032Speter University of Washington. 632838032Speter PORTABILITY FIXES: 632938032Speter Solaris 2.3 had compilation problems in conf.c. Several 633038032Speter people pointed this out. 633138032Speter NetBSD from Charles Hannum of MIT. 633238032Speter AIX4 improvements based on info from Steve Bauer of South 633338032Speter Dakota School of Mines & Technology. 633438032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 633538032Speter Patch from Gil Kloepfer Jr. 633638032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 633738032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 633838032Speter were also in $=w. Problem noted by Zoltan Basti of 633938032Speter Softec. 634038032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 634138032Speter on a patch from Eric Hagberg of Morgan Stanley. 634238032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 634338032Speter of Stanford via Robert La Ferla. 634438032Speter 634564562Sgshapiro8.8.0/8.8.0 1996/09/26 634638032Speter Under some circumstances, Bcc: headers would not be properly 634738032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 634838032Speter Log a warning if the sendmail daemon is invoked without a full 634938032Speter pathname, which prevents "kill -1" from working. I was 635038032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 635138032Speter Fix small buffer overflow. Since the data in this buffer was not 635238032Speter read externally, there was no security problem (and in fact 635338032Speter probably wouldn't really overflow on most compilers). Pointed 635438032Speter out by KIZU takashi of Osaka University. 635538032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 635638032Speter if a FallbackMXHost was specified in the configuration file 635738032Speter -- all mail would be sent to the fallback even if the original 635838032Speter host was accessible. Pointed out by Munenari Hirayama of 635938032Speter NSC (Japan). 636038032Speter A message that didn't terminate with a newline would (sometimes) not 636138032Speter have the trailing "." added properly in the SMTP dialogue, 636238032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 636338032Speter The DaemonPortOptions suboption to bind to a particular address was 636438032Speter incorrect and nonfunctional due to a misunderstanding of the 636538032Speter semantics of binding on a passive socket. Patch from 636638032Speter NIIBE Yutaka of Mitsubishi Research Institute. 636738032Speter Increase the number of MX hosts for a single name to 100 to better 636838032Speter handle the truly huge service providers such as AOL, which 636938032Speter has 13 at the moment (and climbing). In order to avoid 637038032Speter trashing memory, the buffer for all names has only been 637138032Speter slightly increased in size, to 12.8K from 10.2K -- this means 637238032Speter that if a single name had 100 MX records, the average size 637338032Speter of those records could not exceed 128 bytes. Requested by 637438032Speter Brad Knowles of America On Line. 637538032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 637638032Speter Urged by Dan Bernstein of U.C. Berkeley. 637738032Speter Print q_statdate and q_specificity in address structure debugging 637838032Speter printout. 637938032Speter Expand MCI structure flag bits for debugging output. 638038032Speter Support IPv6-style domain literals, which can have colons between 638138032Speter square braces. 638238032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 638338032Speter this is an attempt to track down a bug that one person seems 638438032Speter to be having (it may be a Solaris bug!). 638538032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 638638032Speter this caused the NOTIFY info to sometimes be lost. Problem 638738032Speter pointed out by Claus Assmann of the 638838032Speter Christian-Albrechts-University of Kiel. 638938032Speter The statistics gathered in the sendmail.st file were too high; in 639038032Speter some cases failures (e.g., user unknown or temporary failure) 639138032Speter would count as a delivery as far as the statistics were 639238032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 639338032Speter Systems that don't have flock() would not send split envelopes in 639438032Speter the initial run. Problem pointed out by Leonard Zubkoff of 639538032Speter Dandelion Digital. 639638032Speter Move buffer overflow checking -- these primarily involve distrusting 639738032Speter results that may come from NIS and DNS. 639838032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 639938032Speter include <paths.h> and hence had the wrong pathnames for a few 640038032Speter things like /var/tmp. Reported by Matthew Green. 640138032Speter Conditions were reversed for the Priority: header, resulting in all 640238032Speter values being interpreted as non-urgent except for non-urgent, 640338032Speter which was interpreted as normal. Patch from Bryan Costales. 640438032Speter The -o (optional) flag was being ignored on hash and btree maps 640538032Speter since 8.7.2. Fix from Bryan Costales. 640638032Speter Content-Types listed in class "q" will always be encoded as 640738032Speter Quoted-Printable (or more accurately, will never be encoded 640838032Speter as base64). The class can have primary types (e.g., "text") 640938032Speter or full types (e.g., "text/plain"). Based on a suggestion by 641038032Speter Marius Olafsson of the University of Iceland. 641138032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 641238032Speter dialogue) so it can be passed to programs in mailers. 641338032Speter Define ${bodytype} to be the body type (from the -B flag or the 641438032Speter BODY= ESMTP parameter) so it can be passed to programs in 641538032Speter mailers. 641638032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 641738032Speter flag is set in the mailer descriptor. Suggested by John 641838032Speter Myers of CMU. 641938032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 642038032Speter The command takes a host name; data for that host is 642138032Speter immediately (and asynchronously) flushed. Because this shares 642238032Speter the -qR implementation, other hosts may be attempted, but 642338032Speter there should be no security implications. Implementation 642438032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 642538032Speter Add three new command line flags to pass in DSN parameters: -V envid 642638032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 642738032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 642838032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 642938032Speter that the -N flag applies to all recipients; there is no way 643038032Speter to specify per-address notifications on the command line, 643138032Speter nor is there an equivalent for the ORCPT= per-address 643238032Speter parameter. 643338032Speter Restore LogLevel option to be safe (it can only be increased); 643438032Speter apparently I went into paranoid mode between 8.6 and 8.7 643538032Speter and made it unsafe. Pointed out by Dabe Murphy of the 643638032Speter University of Maryland. 643738032Speter New logging on log level 15: all SMTP traffic. Patches from 643838032Speter Andrew Gross of San Diego Supercomputer Center. 643938032Speter NetInfo property value searching code wasn't stopping when it found 644038032Speter a match. This was causing the wrong values to be found (and 644138032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 644238032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 644338032Speter out by Bill Wisner of Electronics for Imaging that you can't 644438032Speter use the bracket address form for the MAIL_HUB macro, since 644538032Speter that causes the brackets to remain in the envelope recipient 644638032Speter address used for delivery. The simple fix (stripping off the 644738032Speter brackets in the config file) breaks the use of IP literal 644838032Speter addresses. This flag will solve that problem. 644938032Speter Add MustQuoteChars option. This is a list of characters that must 645038032Speter be quoted if they are found in the phrase part of an address 645138032Speter (that is, the full name part). The characters @,;:\()[] are 645238032Speter always in this list and cannot be removed. The default is 645338032Speter this list plus . and ' to match RFC 822. 645438032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 645538032Speter that do not include a host name for back compatibility with 645638032Speter some stupid SMTP clients. Setting this violates RFC 1123 645738032Speter section 5.2.5. 645838032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 645938032Speter rejecting connections if it has more than this many 646038032Speter outstanding children accepting mail. Note that you may 646138032Speter see more processes than this because of outgoing mail; this 646238032Speter is for incoming connections only. 646338032Speter Add ConnectionRateThrottle option. If set to a positive value, the 646438032Speter number of incoming SMTP connections that will be permitted 646538032Speter in a single second is limited to this number. Connections are 646638032Speter not refused during this time, just deferred. The intent is to 646738032Speter flatten out demand so that load average limiting can kick in. 646838032Speter It is less radical than MaxDaemonChildren, which will stop 646938032Speter accepting connections even if all the connections are idle 647038032Speter (e.g., due to connection caching). 647138032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 647238032Speter specifies how long cached information about the state of a 647338032Speter host will be kept before they are considered stale and the 647438032Speter host is retried. If you are using persistent host status 647538032Speter (i.e., the HostStatusDirectory option is set) this will apply 647638032Speter between runs; otherwise, it applies only within a single queue 647738032Speter run and hence is useful only for hosts that have large queues 647838032Speter that take a very long time to run. 647938032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 648038032Speter into being a single line even if they had newlines in them 648138032Speter when read. This is to get around a botch in Lotus Notes. 648238032Speter Text class maps were totally broken -- if you ever retrieved the last 648338032Speter item in a table it would be truncated. Problem noted by 648438032Speter Gregory Neil Shapiro of WPI. 648538032Speter Extend the lines printed by the mailq command (== the -bp flag) when 648638032Speter -v is given to 120 characters; this allows more information 648738032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 648838032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 648938032Speter this was treated as end-of-input. Problem noted by Bryan 649038032Speter Costales. 649138032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 649238032Speter to the queue file. Fix from John Hughes of Atlantic 649338032Speter Technologies, Inc. 649438032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 649538032Speter if this happens in a queue run it can cause nasty delays. 649638032Speter Problem noted by Mark Horton of AT&T. 649738032Speter If userdb entries pointed to userdb entries, and there were multiple 649838032Speter values for a given key, the database cursor would get 649938032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 650038032Speter of Georgia Tech. Fixed by reading all the values and creating 650138032Speter a comma-separated list; thus, the -v output will be somewhat 650238032Speter different for this case. 650338032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 650438032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 650538032Speter of Stanford University. 650638032Speter When envelopes were split due to aliases with owner- aliases, and 650738032Speter there was some error on one of the lists, more than one of 650838032Speter the owners would get the message. Problem pointed out by 650938032Speter Roy Mongiovi of Georgia Tech. 651038032Speter Detect excessive recursion in macro expansions, e.g., $X defined 651138032Speter in terms of $Y which is defined in terms of $X. Problem 651238032Speter noted by Bryan Costales; patch from Eric Wassenaar. 651338032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 651438032Speter some cases get trashed causing bogus From_ lines. Fix from 651538032Speter Kyle Jones of UUNET. 651638032Speter When doing load average initialization, if the nlist call for avenrun 651738032Speter failed, the second and subsequent lookups wouldn't notice 651838032Speter that fact causing bogus load averages to be returned. Noted 651938032Speter by Casper Dik of Sun Holland. 652038032Speter Fix problem with incompatibility with some versions of inet_aton that 652138032Speter have changed the return value to unsigned, so a check for an 652238032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 652338032Speter This could cause mail to addresses such as [foo.com] to bounce 652438032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 652538032Speter Pasteur Institute. 652638032Speter DSNs were inconsistent if a failure occurred during the DATA phase 652738032Speter rather than the RCPT phase: the Action: would be correct, but 652838032Speter the detailed status information would be wrong. Problem noted 652938032Speter by Bob Snyder of General Electric Company. 653038032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 653138032Speter that this is the initial MUA->MTA submission. The flag current 653238032Speter does nothing, but in future releases (when MUAs start using 653338032Speter these flags) it will probably turn on things like DNS 653438032Speter canonification. 653538032Speter Default end-of-line string (E= specification on mailer [M] lines) 653638032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 653738032Speter mailers. 653838032Speter Change the internal definition for the *file* and *include* mailers 653938032Speter to have $u in the argument vectors so that they aren't 654038032Speter misinterpreted as SMTP mailers and thus use \r\n line 654138032Speter termination. This will affect anyone who has redefined 654238032Speter either of these in their configuration file. 654338032Speter Don't assume that IDENT servers close the connection after a query; 654438032Speter responses can be newline terminated. From Terry Kennedy of 654538032Speter St. Peter's College. 654638032Speter Avoid core dumps on erroneous configuration files that have 654738032Speter $#mailer with nothing following. From Bryan Costales. 654838032Speter Avoid null pointer dereference with high debug values in unlockqueue. 654938032Speter Fix from Randy Martin of Clemson University. 655038032Speter Fix possible buffer overrun when expanding very large macros. Fix 655138032Speter from Kyle Jones of UUNET. 655238032Speter After 25 EXPN or VRFY commands, start pausing for a second before 655338032Speter processing each one. This avoids a certain form of denial 655438032Speter of service attack. Potential attack pointed out by Bryan 655538032Speter Costales. 655638032Speter Allow new named (not numbered!) config file rules to do validity 655738032Speter checking on SMTP arguments: check_mail for MAIL commands and 655838032Speter check_rcpt for RCPT commands. These rulesets can do anything 655938032Speter they want; their result is ignored unless they resolve to the 656038032Speter $#error mailer, in which case the indicated message is printed 656138032Speter and the command is rejected. Similarly, the check_compat 656238032Speter ruleset is called before delivery with "from_addr $| to_addr" 656338032Speter (the $| is a meta-symbol used to separate the two addresses); 656438032Speter it can give a "this sender can't send to this recipient" 656538032Speter notification. Note that this patch allows $| to stand alone 656638032Speter in rulesets. 656738032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 656838032Speter that have the name, IP address, and port number (respectively) 656938032Speter of the SMTP client (that is, the entity at the other end of 657038032Speter the connection. These can be used in (e.g.) check_rcpt to 657138032Speter verify that someone isn't trying to relay mail through your 657238032Speter host inappropriately. Be sure to use the deferred evaluation 657338032Speter form, for example $&{client_name}, to avoid having these bound 657438032Speter when sendmail reads the configuration file. 657538032Speter Add new config file rule check_relay to check the incoming connection 657638032Speter information. Like check_compat, it is passed the host name 657738032Speter and host address separated by $| and can reject connections 657838032Speter on that basis. 657938032Speter Allow IDA-style recursive function calls. Code contributed by Mark 658038032Speter Lovell and Paul Vixie. 658138032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 658238032Speter a virtual UUCP address using either a domain address or the $k 658338032Speter macro. Based on code contributed by Mark Lovell and Paul 658438032Speter Vixie. 658538032Speter Add Stanford LDAP map. Requires special libraries that are not 658638032Speter included with sendmail. Contributed by Booker C. Bense 658738032Speter <bbense@networking.stanford.edu>; contact him for support. 658838032Speter See also the src/READ_ME file. 658938032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 659038032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 659138032Speter only for debugging deep bits of code where it is important to 659238032Speter distinguish between the single-character metasymbol $+ and the 659338032Speter two characters $, +. 659438032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 659538032Speter debug_dumpstate. 659638032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 659738032Speter files that are group writable are considered "unsafe" -- that 659838032Speter is, programs and files referenced from such files are not 659938032Speter valid recipients. 660038032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 660138032Speter name that was not in DNS or was a domain-literal. Problem 660238032Speter noted by Tom May. 660338032Speter Change the introduction to error messages to more clearly delineate 660438032Speter permanent from temporary failures; if both existed in a 660538032Speter single message it could be confusing. Suggested by John 660638032Speter Beck of InReference, Inc. 660738032Speter The IngoreDot (i) option didn't work for lines that were terminated 660838032Speter with CRLF. Problem noted by Ted Stockwell of Secure 660938032Speter Computing Corporation. 661038032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 661138032Speter message headers. Problem reported by Matt Dillon of Best 661238032Speter Internet Communications. 661338032Speter Check for bogus characters in the 0200-0237 range; since these are 661438032Speter used internally, very strange errors can occur if those 661538032Speter characters appear in headers. Problem noted by Anders Gertz 661638032Speter of Lysator. 661738032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 661838032Speter recipient mailer has the F=9 flag set, and only works on 661938032Speter text/plain body types. Code contributed by Marius Olafsson 662038032Speter of the University of Iceland. 662138032Speter Special case "postmaster" name so that it is always treated as lower 662238032Speter case in alias files regardless of configuration settings; 662338032Speter this prevents some potential problems where "Postmaster" or 662438032Speter "POSTMASTER" might not match "postmaster". In most cases 662538032Speter this change is a no-op. 662638032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 662738032Speter Costales. 662838032Speter The -a map flag was ignored for dequote maps. Problem noted by 662938032Speter Bryan Costales. 663038032Speter Fix core dump when a lookup of a class "prog" map returns no 663138032Speter response. Patch from Bryan Costales. 663238032Speter Log instances where sendmail is deferring or rejecting connections 663338032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 663438032Speter Include port number in process title for network daemons. Suggested 663538032Speter by Kyle Jones of UUNET. 663638032Speter Send ``double bounces'' (errors that occur when sending an error 663738032Speter message) to the address indicated in the DoubleBounceAddress 663838032Speter option (default: postmaster). Previously they were always 663938032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 664038032Speter Add new mode, -bD, that acts like -bd in all respects except that 664138032Speter it runs in foreground. This is useful for using with a 664238032Speter wrapper that "watches" system services. Suggested by Kyle 664338032Speter Jones of UUNET. 664438032Speter Fix botch in spacing around (parenthesized) comments in addresses 664538032Speter when the comment comes before the address. Patch from 664638032Speter Motonori Nakamura of Kyoto University. 664738032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 664838032Speter that are being bounced to postmaster, rather than "Returned 664938032Speter mail". This permits the person who is postmaster more 665038032Speter easily determine what messages are to their role as 665138032Speter postmaster versus bounces to mail they actually sent. Based 665238032Speter on a suggestion by Motonori Nakamura. 665338032Speter Add new value "time" for QueueSortOrder option; this causes the queue 665438032Speter to be sorted strictly by the time of submission. Note that 665543730Speter this can cause very bad behavior over slow lines (because 665638032Speter large jobs will tend to delay small jobs) and on nodes with 665738032Speter heavy traffic (because old things in the queue for hosts that 665838032Speter are down delay processing of new jobs). Also, this does not 665938032Speter guarantee that jobs will be delivered in submission order 666038032Speter unless you also set DeliveryMode=queue. In general, it should 666138032Speter probably only be used on the command line, and only in 666238032Speter conjunction with -qRhost.domain. In fact, there are very few 666338032Speter cases where it should be used at all. Based on an 666438032Speter implementation by Motonori Nakamura. 666538032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 666638032Speter the same manner as other rulesets. Previously a temporary 666738032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 666838032Speter of Stanford University. 666938032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 667038032Speter 5yz (permanent failure) code. The next MX host will still be 667138032Speter tried if the connection cannot be opened in the first place 667238032Speter or if the MAIL command returns a 4yz (temporary failure) code. 667338032Speter (It's hard to know what to do here, since neither RFC 974 nor 667438032Speter RFC 1123 specify when to proceed to the next MX host.) 667538032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 667638032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 667738032Speter This causes map lookups that get a temporary failure (e.g., 667838032Speter name server failure) to _not_ defer the delivery of the 667938032Speter message. This should only be used if your configuration file 668038032Speter is prepared to do something sensible in this case. Based on 668138032Speter an idea by Gregory Shapiro of WPI. 668238032Speter Fix problem finding network interface addresses. Patch from 668338032Speter Motonori Nakamura. 668438032Speter Don't reject qf entries that are not owned by your effective uid if 668590792Sgshapiro you are not running set-user-ID; this makes management of 668680785Sgshapiro certain kinds of firewall setups difficult. Patch 668780785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 668838032Speter Add persistent host status. This keeps the information normally 668938032Speter maintained within a single queue run in disk files that are 669038032Speter shared between sendmail instances. The HostStatusDirectory 669138032Speter is the directory in which the information is maintained. If 669238032Speter not set, persistent host status is turned off. If not a full 669338032Speter pathname, it is relative to the queue directory. A common 669438032Speter value is ".hoststat". 669538032Speter There are also two new operation modes: 669638032Speter * -bh prints the status of hosts that have had recent 669738032Speter connections. 669838032Speter * -bH purges the host statuses. No attempt is made to save 669938032Speter recent status information. 670038032Speter This feature was originally written by Paul Vixie of Vixie 670138032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 670238032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 670338032Speter with my insistence that things fit cleanly into the V8 670438032Speter framework is gratefully appreciated. 670538032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 670638032Speter operate). Avoids letting two sendmails on the local machine 670764562Sgshapiro open connections to the same remote host at the same time. 670838032Speter This reduces load on the other machine, but can cause mail to 670938032Speter be delayed (for example, if one sendmail is delivering a huge 671038032Speter message, other sendmails won't be able to send even small 671138032Speter messages). Also, it requires another file descriptor (for the 671238032Speter lock file) per connection, so you may have to reduce 671338032Speter ConnectionCacheSize to avoid running out of per-process 671438032Speter file descriptors. Based on the persistent host status code 671538032Speter contributed by Paul Vixie and Mark Lovell. 671638032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 671738032Speter SafeFileEnvironment option is set. Problem noted by Bryan 671838032Speter Costales. 671938032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 672038032Speter file. Problem noted by Bryan Costales. 672138032Speter If a job was aborted using the interrupt signal (e.g., control-C from 672238032Speter the keyboard), on some occasions an empty df file would be 672338032Speter left around; these would collect in the queue directory. 672438032Speter Problem noted by Bryan Costales. 672538032Speter Change the makesendmail script to enhance the search for Makefiles 672638032Speter based on release number. For example, on SunOS 5.5.1, it will 672738032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 672838032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 672938032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 673038032Speter Webmasters. 673138032Speter When creating maps using "newaliases", always map the keys to lower 673238032Speter case when creating the map unless the -f flag is specified on 673338032Speter the map itself. Previously this was done based on the F=u 673438032Speter flag in the local mailer, which meant you could create aliases 673538032Speter that you could never access. Problem noted by Bob Wu of DEC. 673638032Speter When a job was read from the queue, the bits causing notification on 673738032Speter failure or delay were always set. This caused those 673838032Speter notifications to be sent even if NOTIFY=NEVER had been 673938032Speter specified. Problem noted by Steve Hubert of the University 674038032Speter of Washington, Seattle. 674138032Speter Add new configurable routine validate_connection (in conf.c). This 674238032Speter lets you decide if you are willing to accept traffic from 674338032Speter this host. If it returns FALSE, all SMTP commands will return 674438032Speter "550 Access denied". -DTCPWRAPPERS will include support for 674538032Speter TCP wrappers; you will need to add -lwrap to the link line. 674638032Speter (See src/READ_ME for details.) 674738032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 674838032Speter bounces. Some people seemed to think that this could be 674938032Speter confusing (even though it is true). Suggested by Motonori 675038032Speter Nakamura. 675138032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 675238032Speter user early in processing to avoid potential security problems. 675338032Speter However, this means that all .forward and :include: files must 675438032Speter be readable by that user, and all files to be written must be 675538032Speter writable by that user and all programs will be executed by that 675638032Speter user. It is also incompatible with the SafeFileEnvironment 675738032Speter option. In other words, it may not actually add much to 675838032Speter security. However, it should be useful on firewalls and other 675938032Speter places where users don't have accounts and the aliases file is 676038032Speter well constrained. 676138032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 676238032Speter only on the first attempt to delivery to an address. It could 676338032Speter be set to be lower than Timeout.connect on the principle that 676438032Speter the mail should go through quickly to responsive hosts; less 676538032Speter responsive hosts get to wait for the next queue run. 676638032Speter Fix a problem on Solaris that occasionally causes programs 676738032Speter (such as vacation) to hang with their standard input connected 676838032Speter to a UDP port. It also created some signal handling problems. 676938032Speter The problems turned out to be an interaction between vfork(2) 677038032Speter and some of the libraries, particularly NIS/NIS+. I am 677138032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 677238032Speter Change user class map to do the same matching that actual delivery 677338032Speter will do instead of just a /etc/passwd lookup. This adds 677438032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 677538032Speter The Timeout.* options are not safe -- they can be used to create a 677638032Speter denial-of-service attack. Problem noted by Christophe 677738032Speter Wolfhugel. 677843730Speter Don't send PostmasterCopy messages in the event of a "delayed" 677938032Speter notification. Suggested by Barry Bouwsma. 678038032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 678138032Speter option is set, since this disables VERB mode. Suggested 678238032Speter by John Hawkinson of MIT. 678338032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 678438032Speter by Motonori Nakamura of Kyoto University. 678538032Speter Only queue messages on transient .forward open failures if there 678643730Speter were no successful opens. The previous behavior caused it 678738032Speter to queue even if a "fall back" .forward was found. Problem 678838032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 678938032Speter and Computer Science (DISCS), NUS, Singapore. 679038032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 679138032Speter is bouncing because of a MIME error during 8->7 bit conversion; 679238032Speter the encapsulated message will bounce again, causing a loop. 679338032Speter Problem noted by Steve Hubert of the University of Washington. 679438032Speter Create xf (transcript) files using the TempFileMode option value 679538032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 679638032Speter National University of Singapore. 679738032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 679838032Speter detect cases where DefaultUid is set to something that the 679938032Speter system can't cope with. 680038032Speter PORTABILITY FIXES: 680138032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 680238032Speter Atlas International. 680338032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 680438032Speter <bicknell@ufp.org>. 680538032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 680638032Speter work on the first recipient of a message due to a 680738032Speter bug in the getpwent family.

Contributed by 685238032Speter Robert La Ferla of Hot Software. 685338032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 685438032Speter (where "code" is an exit status) on domains (previously 685538032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 685638032Speter Foundation. 685738032Speter CONFIG: hooks for IPv6-style domain literals. 685838032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 685938032Speter if it is undefined the AliasFile option is never set; this 686038032Speter should be transparent for most everyone. Suggested by John 686138032Speter Myers of CMU. 686238032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 686338032Speter domain listed in $=w is masqueraded. With it, only those 686438032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 686538032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 686638032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 686738032Speter hosts under those domains as well as the domain headers 686838032Speter themselves. For example, if a configuration had 686938032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 687038032Speter foo.com would be masqueraded; with it, *.foo.com would be 687138032Speter masqueraded as well. Based on an implementation by Richard 687238032Speter (Pug) Bainter of U. Texas. 687338032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 687438032Speter outgoing addresses.

Yes, 687638032Speter this does overlap with the user database, and figuring out 687738032Speter just when to use which one may be tricky. Based on code 687838032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 687938032Speter from Per Hedeland of Ericsson. 688038032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 688138032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 688238032Speter Keys are either fully qualified addresses or just the host 688338032Speter part (with the @ sign). For example, a table containing: 688438032Speter info@foo.com foo-info 688538032Speter info@bar.com bar-info 688638032Speter @baz.org jane@elsewhere.net 688738032Speter would send all mail destined for info@foo.com to foo-info 688838032Speter (which is presumably an alias), mail addressed to info@bar.com 688938032Speter to bar-info, and anything addressed to anyone at baz.org will 689038032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 689138032Speter and baz.org must all be in $=w. Based on discussions with 689238032Speter a great many people. 689338032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 689438032Speter Suggested by Richard Bainter. 689538032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 689638032Speter "fax" mailer. 689738032Speter CONFIG: allow mailertable entries to resolve to local:user; this 689838032Speter passes the original user@host in to procmail-style local 689938032Speter mailers as the "detail" information to allow them to do 690038032Speter additional clever processing. From Joe Pruett of 690138032Speter Teleport Corporation. Delivery to the original user can 690238032Speter be done by specifying "local:" (with nothing after the colon). 690338032Speter CONFIG: allow any context that takes "mailer:domain" to also take 690438032Speter "mailer:user@domain" to force mailing to the given user; 690538032Speter "local:user" can also be used to do local delivery. This 690638032Speter applies on *_RELAY and in the mailertable entries. Based 690738032Speter on a suggestion by Ribert Kiessling of Easynet. 690838032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 690938032Speter limits the possible domains; this reduces the number of DNS 691038032Speter lookups required to support this feature. For example, 691138032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 691238032Speter to domains under my.site.com. Code contributed by Anthony 691338032Speter Thyssen <anthony@cit.gu.edu.au>. 691438032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 691538032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 691638032Speter of WPI. 691738032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 691838032Speter event you have to define local mailers. Suggested by 691938032Speter Gregory Shapiro of WPI. 692038032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 692138032Speter be misinterpreted as a list:...; syntax. Based on a patch by 692238032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 692338032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 692438032Speter remotely connected. The address host!user was being 692538032Speter converted to host!user@thishost instead of host!user@uurelay. 692638032Speter Problem noted by William Gianopoulos of Raytheon Company. 692738032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 692838032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 692938032Speter "User has moved"; the former wording was confusing if the 693038032Speter new address is still on the local host. Based on a suggestion 693138032Speter by Andreas Luik. 693238032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 693338032Speter However, the class is not pre-initialized to contain root. 693438032Speter Suggested by Gregory Neil Shapiro. 693538032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 693638032Speter Wolfhugel. 693738032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 693838032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 693938032Speter well: this produces a slightly different mailbox format (no 694038032Speter Content-Length: headers), file ownerships and modes are 694138032Speter different (not owned by group mail; mode 600 instead of 660), 694238032Speter and the local mailer flags will have to be tweaked (make them 694338032Speter match bsd4.4) in order to use this mailer. Patches from Paul 694438032Speter Hammann of the Missouri Research and Education Network. 694538032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 694638032Speter was a delivery error, such as if the ownership on the file 694738032Speter was wrong or the mode changed between the initial stat and 694838032Speter the open. Problem reported by William Colburn of the New 694938032Speter Mexico Institute of Mining and Technology. 695038032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 695138032Speter Costales. 695238032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 695338032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 695438032Speter honored. Fix from Michael Scott Shappe. 695538032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 695638032Speter NEW FILES: 695738032Speter src/Makefiles/Makefile.AIX.2 695838032Speter src/Makefiles/Makefile.IRIX.6.2 695938032Speter src/Makefiles/Makefile.maxion 696038032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 696138032Speter src/Makefiles/Makefile.SCO.5.x 696238032Speter src/Makefiles/Makefile.UXPDSV20 696338032Speter mailstats/mailstats.8 696438032Speter praliases/praliases.8 696538032Speter cf/cf/generic-nextstep3.3.mc 696638032Speter cf/feature/genericstable.m4 696738032Speter cf/feature/limited_masquerade.m4 696838032Speter cf/feature/masquerade_entire_domain.m4 696938032Speter cf/feature/virtusertable.m4 697038032Speter cf/ostype/aix2.m4 697138032Speter cf/ostype/altos.m4 697238032Speter cf/ostype/maxion.m4 697338032Speter cf/ostype/solaris2.ml.m4 697438032Speter cf/ostype/uxpds.m4 697538032Speter contrib/re-mqueue.pl 697638032Speter DELETED FILES: 697738032Speter src/Makefiles/Makefile.Solaris 697838032Speter contrib/xla/README 697938032Speter contrib/xla/xla.c 698038032Speter RENAMED FILES: 698138032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 698238032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 698338032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 698438032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 698538032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 698638032Speter 698764562Sgshapiro8.7.6/8.7.3 1996/09/17 698838032Speter SECURITY: It is possible to force getpwuid to fail when writing the 698938032Speter queue file, causing sendmail to fall back to running programs 699038032Speter as the default user. This is not exploitable from off-site. 699138032Speter Workarounds include using a unique user for the DefaultUser 699238032Speter (old u & g options) and using smrsh as the local shell. 699338032Speter SECURITY: fix some buffer overruns; in at least one case this allows 699438032Speter a local user to get root. This is not known to be exploitable 699538032Speter from off-site. The workaround is to disable chfn(1) commands. 699638032Speter 699764562Sgshapiro8.7.5/8.7.3 1996/03/04 699838032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 699938032Speter in some case cause connections to hang or messages to have 700038032Speter extra spaces in odd places. Patch from Eric Wassenaar; 700138032Speter reports from Eric Hall of Chiron Corporation, Stephen 700238032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 700338032Speter and others. 700438032Speter 700564562Sgshapiro8.7.4/8.7.3 1996/02/18 700638032Speter SECURITY: In some cases it was still possible for an attacker to 700738032Speter insert newlines into a queue file, thus allowing access to 700838032Speter any user (except root). 700938032Speter CONFIG: no changes -- it is not a bug that the configuration 701038032Speter version number is unchanged. 701138032Speter 701264562Sgshapiro8.7.3/8.7.3 1995/12/03 701338032Speter Fix botch in name server timeout in RCPT code; this problem caused 701438032Speter two responses in SMTP, which breaks things horribly. Fix 701538032Speter from Gregory Neil Shapiro of WPI. 701638032Speter Verify that L= value on M lines cannot be negative, which could cause 701738032Speter negative array subscripting. Not a security problem since 701838032Speter this has to be in the config file, but it could have caused 701938032Speter core dumps. Pointed out by Bryan Costales. 702038032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 702138032Speter Costales. 702238032Speter PORTABILITY FIXES: 702338032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 702438032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 702538032Speter order. Tweak it to work properly. Based on fixes 702638032Speter from Fletcher Mattox of UTexas and Betty Lee of 702738032Speter Stanford University. 702838032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 702938032Speter Deficiency pointed out by Bryan Costales of ICSI. 703038032Speter 703164562Sgshapiro8.7.2/8.7.2 1995/11/19 703238032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 703338032Speter OperatorChars, and UnixFromLine options. They were not 703438032Speter properly repaired in 8.7.1. 703538032Speter Completely delete the Bcc: header if and only if there are other 703638032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 703738032Speter last being a historic botch, of course). If Bcc: is the 703838032Speter only recipient header in the message, its value is tossed, 703943730Speter but the header name is kept. The old behavior (always keep 704038032Speter the header name and toss the value) allowed primary recipients 704138032Speter to see that a Bcc: went to _someone_. 704238032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 704338032Speter sender to <address> using -f'' syslog messages. Suggested 704438032Speter by Kari Hurtta. 704538032Speter If a sequence or switch map lookup entry gets a tempfail but then 704638032Speter continues on to another map type, but the name is not found, 704738032Speter return a temporary failure from the sequence or switch map. 704838032Speter For example, if hosts search ``dns files'' and DNS fails 704938032Speter with a tempfail, the hosts map will go on and search files, 705038032Speter but if it fails the whole thing should be a tempfail, not 705138032Speter a permanent (host unknown) failure, even though that is the 705238032Speter failure in the hosts.files map. This error caused hard 705338032Speter bounces when it should have requeued. 705438032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 705590792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 705638032Speter working properly due to excessive paranoia. Pointed out by 705738032Speter John Hawkinson of Panix. 705838032Speter An SMTP RCPT command referencing a host that gave a nameserver 705938032Speter timeout would return a 451 command (8.6 accepted it and 706043730Speter queued it locally). Revert to the 8.6 behavior in order 706138032Speter to simplify queue management for clustered systems. Suggested 706238032Speter by Gregory Neil Shapiro of WPI. The same problem could break 706338032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 706438032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 706538032Speter Infobiogen. 706638032Speter Fix possible buffer overflow in munchstring(). This was not a security 706738032Speter problem because you couldn't specify any argument to this 706838032Speter without first giving up root privileges, but it is still a 706938032Speter good idea to avoid future problems. Problem noted by John 707038032Speter Hawkinson and Sam Hartman of MIT. 707138032Speter ``452 Out of disk space for temp file'' messages weren't being 707238032Speter printed. Fix from David Perlin of Nanosoft. 707343730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 707438032Speter is not set, since this is required to get the actual DSNs 707538032Speter created. Problem pointed out by John Gardiner Myers of CMU. 707638032Speter Log permission problems that cause .forward and :include: files to 707738032Speter be untrusted or ignored on log level 12 and higher. Suggested 707838032Speter by Randy Martin of Clemson University. 707938032Speter Allow user ids in U= clauses of M lines to have hyphens and 708038032Speter underscores. 708138032Speter Fix overcounting of recipients -- only happened when sending to an 708238032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 708338032Speter of Systems and Computer Technology Corporation. 708438032Speter If a message is sent to an address that fails, the error message that 708538032Speter is returned could show some extraneous "success" information 708638032Speter included even if the user did not request success notification, 708738032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 708838032Speter Config files that had no AliasFile definition were defaulting to 708938032Speter using /etc/aliases; this caused problems with nullclient 709038032Speter configurations. Change it back to the 8.6 semantics of 709138032Speter having no local alias file unless it is declared. Problem 709238032Speter noted by Charles Karney of Princeton University. 709338032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 709438032Speter Costales of ICSI. 709538032Speter Map lookups of class "userdb" maps were always case sensitive; they 709638032Speter should be controlled by the -f flag like other maps. Pointed 709738032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 709838032Speter Fix problem that caused some addresses to be passed through ruleset 5 709938032Speter even when they were tagged as "sticky" by prefixing the 710038032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 710138032Speter Technological University. 710238032Speter When converting a message to Quoted-Printable, prevent any lines with 710338032Speter dots alone on a line by themselves. This is because of the 710438032Speter preponderance of broken mailers that still get this wrong. 710538032Speter Code contributed by Per Hedeland of Ericsson. 710638032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 710738032Speter out by Bjart Kvarme of USIT/UiO (Norway). 710838032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 710938032Speter Requested by Allan Johannesen. 711038032Speter Delete check for text format of alias files -- it should be legal 711138032Speter to have the database format of the alias files without the 711238032Speter text version. Problem pointed out by Joe Rhett of Navigist, 711338032Speter Inc. 711438032Speter If "Ot" was specified with no value, the TZ variable was not properly 711538032Speter imported from the environment. Pointed out by Frank Crawford 711638032Speter <frank@ansto.gov.au>. 711738032Speter Some architectures core dumped on "program" maps that didn't have 711838032Speter extra arguments. Patch from Booker C. Bense of Stanford 711938032Speter University. 712038032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 712138032Speter the parent should do this. Fix from Brian Coan of the 712238032Speter Association for Progressive Communications. 712338032Speter If MinQueueAge was set and a message was considered but not run 712438032Speter during a queue run and the Timeout.queuereturn interval was 712538032Speter reached, a "timed out" error message would be returned that 712638032Speter didn't include the failed address (and claimed to be a warning 712738032Speter even though it was fatal). The fix is to not return such 712838032Speter messages until they are actually tried, i.e., in the next 712938032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 713038032Speter SINTEF RUNIT, Oslo. 713138032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 713238032Speter that have the hes_getmailhost() routine.

Bug 717938032Speter pointed out by John Hawkinson of MIT. 718038032Speter Fix strange case of an executable called by a program map that 718138032Speter returns a value but also a non-zero exit status; this 718238032Speter would give contradictory results in the higher level; in 718338032Speter particular, the default clause in the map lookup would be 718438032Speter ignored. Change to ignore the value if the program returns 718538032Speter non-zero exit status. From Tom Moore of AT&T GIS. 718638032Speter Shorten parameters passed to syslog() in some contexts to avoid a 718738032Speter bug in many vendors' implementations of that routine. Although 718838032Speter this isn't really a bug in sendmail per se, and my solution 718938032Speter has to assume that syslog() has at least a 1K buffer size 719038032Speter internally (I know some vendors have shortened this 719138032Speter dramatically -- they're on their own), sendmail is a popular 719238032Speter target. Also, limit the size of %s arguments in sprintf. 719338032Speter These both have possible security implications. Solutions 719438032Speter suggested by Casper Dik of Sun's Network Security Group 719538032Speter (Holland), Mark Seiden, and others. 719638032Speter Fix a problem that might cause a non-standard -B (body type) 719738032Speter parameter to be passed to the next server with undefined 719838032Speter results. This could have security implications. 719938032Speter If a filesystem was at > 100% utilization, the freediskspace() 720038032Speter routine incorrectly returned an error rather than zero. 720138032Speter Problem noted by G. Paul Ziemba of Alantec. 720238032Speter Change MX sort order so that local hostnames (those in $=w) always 720338032Speter sort first within a given preference. This forces the bestmx 720438032Speter map to always return the local host first, if it is included 720538032Speter in the list of highest priority MX records. From K. Robert 720638032Speter Elz. 720738032Speter Avoid some possible null pointer dereferences. Fixes from Randy 720838032Speter Martin <WOLF@CLEMSON.EDU> 720938032Speter When sendmail starts up on systems that have no fully qualified 721038032Speter domain name (FQDN) anywhere in the first matching host map 721138032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 721238032Speter sendmail would sleep to try to find a FQDN, which it really 721338032Speter really needs. This has been changed to fall through to the 721438032Speter next map type if it can't find a FQDN -- i.e., if the hosts 721538032Speter file doesn't have a FQDN, it will try dns even though the 721638032Speter short name was found in /etc/hosts. This is probably a crock, 721738032Speter but many people have hosts files without FQDNs. Remember: 721838032Speter domain names are your friends. 721938032Speter Log a high-priority message if you can't find your FQDN during startup. 722038032Speter Suggested by Simon Barnes of Schlumberger Limited. 722138032Speter When using Hesiod, initialize it early to improve error reporting. 722238032Speter Patch from Don Lewis of Silicon Systems, Inc. 722338032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 722438032Speter connection timeout in the kernel. Add a new "connect" timeout 722538032Speter to limit this time. Defaults to zero (use whatever the 722638032Speter kernel provides). Based on code contributed by J.R. Oldroyd 722738032Speter of TerraNet. 722838032Speter Under some circumstances, a failed message would not be properly 722938032Speter removed from the queue, causing tons of bogus error messages. 723038032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 723138032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 723238032Speter of WPI. 723338032Speter PORTABILITY FIXES: 723438032Speter On IRIX 5.x, there was an inconsistency in the setting 723538032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 725138032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 725238032Speter otherwise the F=S causes the From_ line to imply that root is 725338032Speter the sender. Problem pointed out by Claude Scarpelli of 725438032Speter Infobiogen (France). 725538032Speter NEW FILES: 725638032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 725738032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 725838032Speter src/Makefiles/Makefile.UXPDS 725938032Speter 726064562Sgshapiro8.7/8.7 1995/09/16 726138032Speter Fix a problem that could cause sendmail to run out of file 726238032Speter descriptors due to a trashed data structure after a 726338032Speter vfork.

This was used "safely" in the sense 726938032Speter that it only did a stat, but it would have set the 727038032Speter map modification time improperly. Problem pointed out 727138032Speter by Roy Mongiovi of Georgia Tech. 727238032Speter Clean up the Subject: line on warning messages and return 727338032Speter receipts so that they don't say "Returned mail:"; this 727438032Speter can be confusing. 727538032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 727638032Speter useful enough to make it worthwhile printing on "-d". 727738032Speter Avoid logging alias statistics every time you read the alias 727838032Speter file on systems with no database method compiled in. 727938032Speter If you have a name with a trailing dot, and you try looking it 728038032Speter up using gethostbyname without the dot (for /etc/hosts 728138032Speter compatibility), be sure to turn off RES_DEFNAMES and 728238032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 728338032Speter Problem noted by Charles Amos of the University of 728438032Speter Maryland. 728538032Speter Don't do timeouts in collect if you are not running SMTP. 728638032Speter There is nothing that says you can't have a long 728738032Speter running program piped into sendmail (possibly via 728838032Speter /bin/mail, which just execs sendmail). Problem reported 728938032Speter by Don "Truck" Lewis of Silicon Systems. 729038032Speter Try gethostbyname() even if the DNS lookup fails iff option I 729138032Speter is not set. This allows you to have hosts listed in 729238032Speter NIS or /etc/hosts that are not known to DNS. It's normally 729338032Speter a bad idea, but can be useful on firewall machines. This 729438032Speter should really be broken out on a separate flag, I suppose. 729538032Speter Avoid compile warnings against BIND 4.9.3, which uses function 729638032Speter prototypes.

From Kyle Jones of UUNET. 730138032Speter SECURITY: avoid denial-of-service attacks possible by destroying 730238032Speter the alias database file by setting resource limits low. 730338032Speter This involves adding two new compile-time options: 730438032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 730538032Speter available) and HASULIMIT (indicating that ulimit(2) support 730638032Speter is available -- the Release 3 form is used). The former 730738032Speter is assumed on BSD-based systems, the latter on System 730838032Speter V-based systems. Attack noted by Phil Brandenberger of 730938032Speter Swarthmore University. 731038032Speter New syntaxes in test (-bt) mode: 731138032Speter ``.Dmvalue'' will define macro "m" to "value". 731238032Speter ``.Ccvalue'' will add "value" to class "c". 731338032Speter ``=Sruleset'' will dump the contents of the indicated 731438032Speter ruleset. 731538032Speter ``=M'' will display the known mailers. 731638032Speter ``-ddebug-spec'' is equivalent to the command-line 731738032Speter -d debug flag. 731838032Speter ``$m'' will print the value of macro $m. 731938032Speter ``$=c'' will print the contents of class $=c. 732038032Speter ``/mx host'' returns the MX records for ``host''. 732138032Speter ``/parse address'' will parse address, returning the value of 732238032Speter crackaddr (essentially, the comment information) 732338032Speter and the parsed address. 732438032Speter ``/try mailer address'' will rewrite address into the form 732538032Speter it will have when presented to the indicated mailer. 732638032Speter ``/tryflags flags'' will set flags used by parsing. The 732738032Speter flags can be `H' for header or `E' for envelope, 732838032Speter and `S' for sender or `R' for recipient. These 732938032Speter can be combined, so `HR' sets flags for header 733038032Speter recipients. 733138032Speter ``/canon hostname'' will try to canonify hostname and 733238032Speter return the result. 733338032Speter ``/map mapname key'' will look up `key' in the indicated 733438032Speter `mapname' and return the result. 733538032Speter Somewhat better handling of UNIX-domain socket addresses -- it 733638032Speter should show the pathname rather than hex bytes. 733738032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 733838032Speter the header for envelope sender information and uses 733938032Speter CR-LF as message terminators. It was thought to be 734038032Speter obsolete (used only for Arpanet NCP protocols), but it 734138032Speter turns out that the UK ``Grey Book'' protocols require 734238032Speter that functionality. 734338032Speter Fix a fix in previous release -- if gethostname and gethostbyname 734438032Speter return a name without dots, and if an attempt to canonify 734538032Speter that name fails, wait one minute and try again. This can 734638032Speter result in an extra 60 second delay on startup if your system 734738032Speter hostname (as returned by hostname(1)) has no dot and no names 734838032Speter listed in /etc/hosts or your NIS map have a dot. 734938032Speter Check for proper domain name on HELO and EHLO commands per 735038032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 735138032Speter of Michigan Technological University. 735238032Speter Relax chownsafe rules slightly -- old version said that if you 735338032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 735438032Speter if fpathconf returned EINVAL or ENOSYS), assume that 735538032Speter chown is not safe. The new version falls back to whether 735638032Speter you are on a BSD system or not. This is important for 735738032Speter SunOS, which apparently always returns one of those 735838032Speter error codes. This impacts whether you can mail to files 735938032Speter or not. 736038032Speter Syntax errors such as unbalanced parentheses in the configuration 736138032Speter file could be omitted if you had "Oem" prior to the 736238032Speter syntax error in the config file. Change to always print 736338032Speter the error message. It was especially weird because it 736438032Speter would cause a "warning" message to be sent to the Postmaster 736538032Speter for every message sent (but with no transcript). Problem 736638032Speter noted by Gregory Paris of Motorola. 736738032Speter Rewrite collect and putbody to handle full 8-bit data, including 736838032Speter zero bytes.

This is to handle the 743738032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 743838032Speter assume that ``group name:'' is a comment on the first 743938032Speter address and the ``;'' is a comment on the last address). 744038032Speter This requires config file support to get right. It does 744138032Speter understand that :: is NOT this syntax, and can be turned 744238032Speter off completely by setting the ColonOkInAddresses option. 744338032Speter Level 6 config files added with new mailer flags: 744438032Speter A Addresses are aliasable. 744538032Speter i Do udb rewriting on envelope as well as header 744638032Speter sender lines. Applies to the from address mailer 744738032Speter flags rather than the recipient mailer flags. 744838032Speter j Do udb rewriting on header recipient addresses. 744938032Speter Applies to the sender mailer flags rather than the 745038032Speter recipient mailer flags. 745138032Speter k Disable check for loops when doing HELO command. 745238032Speter o Always run as the mail recipient, even on local 745338032Speter delivery. 745438032Speter w Check for an /etc/passwd entry for this user. 745538032Speter 5 Pass addresses through ruleset 5. 745638032Speter : Check for :include: on this address. 745738032Speter | Check for |program on this address. 745838032Speter / Check for /file on this address. 745938032Speter @ Look up sender header addresses in the user 746038032Speter database. Applies to the mailer flags for the 746138032Speter mailer corresponding to the envelope sender 746238032Speter address, rather than to recipient mailer flags. 746338032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 746438032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 746538032Speter mailers, and the ColonOkInAddresses option. 746638032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 746738032Speter John Beck of Hewlett-Packard, who generously contributed 746838032Speter their implementation to me, which I then didn't use (see 746938032Speter mime.c for an explanation of why). This adds the 747038032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 747138032Speter to control handling of 8-bit data. These have to cope with 747238032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 747338032Speter 8-bit data that is entered without declaring it as 8-bit 747438032Speter MIME -- technically this is illegal according to the 747538032Speter specs) and labelled 8-bit data (that is, it was declared 747638032Speter as 8BITMIME in the ESMTP session or by using the 747738032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 747838032Speter set then 8-bit data is sent to non-8BITMIME machines 747938032Speter instead of converting to 7 bit (essentially using 748038032Speter just-send-8 semantics). The values for EightBitMode are: 748138032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 748238032Speter any necessary conversion of 8BITMIME to 7BIT 748338032Speter (essentially, the full MIME option). 748438032Speter p pass unlabelled 8-bit input, but convert labelled 748538032Speter 8BITMIME input to 7BIT as required (default). 748638032Speter s strict adherence: reject unlabelled 8-bit input, 748738032Speter convert 8BITMIME to 7BIT as required. The F=8 748838032Speter flag is ignored. 748938032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 749038032Speter the setting of F=8. 749138032Speter Add new internal class 'n', which is the set of MIME Content-Types 749238032Speter which can not be 8 to 7 bit encoded because of other 749338032Speter considerations. Types "multipart/*" and "message/*" are 749438032Speter never directly encoded (although their components can be). 749538032Speter Add new internal class 's', which is the set of subtypes of the 749638032Speter MIME message/* content type that can be treated as though 749738032Speter they are an RFC822 message. It is predefined to have 749838032Speter "rfc822". Suggested By Kari Hurtta. 749938032Speter Add new internal class 'e'. This is the set of MIME 750038032Speter Content-Transfer-Encodings that can be converted to 750138032Speter a seven bit format (Quoted-Printable or Base64). It is 750238032Speter preinitialized to contain "7bit", "8bit", and "binary". 750338032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 750438032Speter short name) to set the default character set to use in the 750538032Speter Content-Type: header when doing encoding of an 8-bit message 750638032Speter which isn't marked as MIME into MIME format. If the C= 750738032Speter parameter is set on the Envelope From address, use that as 750838032Speter the default encoding; else use the DefaultCharSet option. 750938032Speter If neither is set, it defaults to "unknown-8bit" as 751038032Speter suggested by RFC 1428 section 3. 751138032Speter Allow ``U=user:group'' field in mailer definition to set a default 751238032Speter user and group that a mailer will be executed as. This 751338032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 751438032Speter also set, it is the uid/gid that will always be used (that 751538032Speter is, the controlling address is ignored). The values may be 751638032Speter numeric or symbolic; if only a symbolic user is given (no 751738032Speter group) that user's default group in the passwd file is used 751838032Speter as the group. Based on code donated by Chip Rosenthal of 751938032Speter Unicom. 752038032Speter Allow `u' option to also accept user:group as a value, in the same 752138032Speter fashion as the U= mailer option. 752238032Speter Add the symbolic time zone name in the Arpanet format dates (as 752338032Speter a comment). This adds a new compile-time configuration 752438032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 752538032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 752638032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 752738032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 752838032Speter timezone()), or TZ_NONE (don't include the comment). Code 752938032Speter from Chip Rosenthal. 753038032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 753138032Speter For example, 753238032Speter O Timeout.helo = 2m 753338032Speter There are also two new suboptions "queuereturn" and 753438032Speter "queuewarn"; these subsume the old T option. Thus, to 753538032Speter set them both the preferred new syntax is 753638032Speter O Timeout.queuereturn = 5d 753738032Speter O Timeout.queuewarn = 4h 753838032Speter Sort queue by host name instead of by message priority if the 753938032Speter QueueSortOrder option (no short name) is set is set to 754038032Speter ``host''. This makes better use of the connection cache, 754138032Speter but may delay more ``interactive'' messages behind large 754238032Speter backlogs under some circumstances. This is probably a 754338032Speter good option if you have high speed links or don't do lots 754438032Speter of ``batch'' messages, but less good if you are using 754538032Speter something like PPP on a 14.4 modem. Based on code 754638032Speter contributed by Roy Mongiovi of Georgia Tech (my main 754738032Speter contribution was to make it configurable). 754838032Speter Save i-number of df file in qf file to simplify rebuilding of queue 754938032Speter after disastrous disk crash. Suggested by Kyle Jones of 755038032Speter UUNET; closely based on code from KJS DECWRL code written 755138032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 755238032Speter are NOT back compatible with 8.6 -- that is, you can convert 755338032Speter from 8.6 to 8.7, but not the other direction. 755438032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 755538032Speter route-addrs in envelopes; this is because in some cases 755638032Speter they can be sent to the shell, which interprets them as 755738032Speter I/O redirection. 755838032Speter Don't include error file (option E) with return-receipts; this 755938032Speter can be confusing. 756038032Speter Don't send "Warning: cannot send" messages to owner-* or 756138032Speter *-request addresses. Suggested by Christophe Wolfhugel 756238032Speter of the Institut Pasteur, Paris. 756338032Speter Allow -O command line flag to set long form options. 756438032Speter Add "MinQueueAge" option to set the minimum time between attempts 756538032Speter to run the queue. For example, if the queue interval 756638032Speter (-q value) is five minutes, but the minimum queue age 756738032Speter is fifteen minutes, jobs won't be tried more often than 756838032Speter once every fifteen minutes. This can be used to give 756938032Speter you more responsiveness if your delivery mode is set to 757038032Speter queue-only. 757138032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 757238032Speter :include: and .forward files. 757338032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 757438032Speter key field name, the value field name, and the field 757538032Speter delimiter. The field delimiter can be a single character 757638032Speter or the sequence "\t" or "\n" for tab or newline. 757738032Speter These are for use by NIS+ and similar access methods. 757838032Speter Change maps to always strip quotes before lookups; the -q flag 757943730Speter turns off this behavior. Suggested by Motonori Nakamura. 758038032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 758138032Speter key and value field names respectively. Code donated by 758238032Speter Sun Microsystems. 758338032Speter Add "hesiod" map class. The "file name" is used as the 758438032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 758538032Speter first value found for the match. Code donated by Scott 758638032Speter Hutton of Indiana University. 758738032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 758838032Speter specify the name of the property that is searched as the 758938032Speter key and a -v flag to specify the name of the property that 759038032Speter is returned as the value (defaults to "members"). The 759138032Speter default map is "/aliases". Some code based on code 759238032Speter contributed by Robert La Ferla of Hot Software. 759338032Speter Add "text" map class. This does slow, linear searches through 759438032Speter text files. The -z flag specifies a column delimiter 759538032Speter (defaults to any sequence of white space), the -k flag 759638032Speter sets the key column number, and the -v flag sets the 759738032Speter value column number. Lines beginning with `#' are treated 759838032Speter as comments. 759938032Speter Add "program" map class to execute arbitrary programs. The search 760038032Speter key is presented as the last argument; the output is one 760138032Speter line read from the programs standard output. Exit statuses 760238032Speter are from sysexits.h. 760338032Speter Add "sequence" map class -- searches maps in sequence until it 760438032Speter finds a match. For example, the declarations: 760538032Speter Kmap1 ... 760638032Speter Kmap2 ... 760738032Speter Kmapseq sequence map1 map2 760838032Speter defines a map "mapseq" that first searches map1; if the 760938032Speter value is found it is returned immediately, otherwise 761038032Speter map2 is searched and the value returned. 761138032Speter Add "switch" map class. This is much like "sequence" except that 761238032Speter the ordering is fetched from an external file, usually 761338032Speter the system service switch. The parameter is the name of 761438032Speter the service to switch on, and the maps that it will use 761538032Speter are the name of the switch map followed by ".service_type". 761638032Speter For example, if the declaration of the map is 761738032Speter Ksample switch hosts 761838032Speter and the system service switch specifies that hosts are 761938032Speter looked up using dns and nis in that order, then this is 762038032Speter equivalent to 762138032Speter Ksample sequence sample.dns sample.nis 762238032Speter The subordinate maps (sample.*) must already be defined. 762338032Speter Add "user" map class -- looks up users using getpwnam. Takes a 762438032Speter "-v field" flag on the definition that tells what passwd 762538032Speter entry to return -- legal values are name, passwd, uid, gid, 762638032Speter gecos, dir, and shell. Generally expected to be used with 762738032Speter the -m (matchonly) flag. 762838032Speter Add "bestmx" map class -- returns the best MX value for the host 762938032Speter listed as the value. If there are several "best" MX records 763038032Speter for this host, one will be chosen at random. 763138032Speter Add "userdb" map class -- looks up entries in the user database. 763238032Speter The "file name" is actually the tag that will be used, 763338032Speter typically "mailname". If there are multiple entries 763438032Speter matching the name, the one chosen is undefined. 763538032Speter Add multiple queue timeouts (both return and warning). These are 763638032Speter set by the Precedence: or Priority: header fields to one of 763738032Speter three values. If a Priority: is set and has value "normal", 763864562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 763938032Speter used. If no priority is set, the Precedence: is consulted; 764038032Speter if negative, non-urgent timeouts are used; if greater than 764138032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 764238032Speter are used. The timeouts are set by setting the six timeouts 764338032Speter queue{warn,return}.{urgent,normal,non-urgent}. 764438032Speter Fix problem when a mail address is resolved to a $#error mailer 764538032Speter with a temporary failure indication; it works in SMTP, 764638032Speter but when delivering locally the mail is silently discarded. 764738032Speter This patch, from Kyle Jones of UUNET, bounces it instead 764838032Speter of queueing it (queueing is very hard). 764938032Speter When using /etc/hosts or NIS-style lookups, don't assume that 765038032Speter the first name in the list is the best one -- instead, 765138032Speter search for the first one with a dot. For example, if 765238032Speter an /etc/hosts entry reads 765338032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 765438032Speter this change will use the second name as the canonical 765538032Speter machine name instead of the initial, unqualified name. 765638032Speter Change dequote map to replace spaces in quoted text with a value 765738032Speter indicated by the -s flag on the dequote map definition. 765838032Speter For example, ``Mdequote dequote -s_'' will change 765938032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 766038032Speter quoted (because of the space character). Suggested by Dan 766138032Speter Oscarsson for use in X.400 addresses. 766238032Speter Implement long macro names as ${name}; long class names can 766338032Speter be similarly referenced as $={name} and $~{name}. 766438032Speter Definitions are (e.g.) ``D{name}value''. Names that have 766538032Speter a leading lower case letter or punctuation characters are 766638032Speter reserved for internal use by sendmail; i.e., config files 766738032Speter should use names that begin with a capital letter. Based 766838032Speter on code contributed by Dan Oscarsson. 766938032Speter Fix core dump if getgrgid returns a null group list (as opposed 767038032Speter to an empty group list, that is, a pointer to a list 767138032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 767238032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 767338032Speter failed, it called syserr which called newstr which called 767438032Speter xalloc.... The newstr is now avoided for "panic" messages. 767538032Speter Reported by Stuart Kemp of James Cook University. 767638032Speter Improve connection cache timeouts; previously, they were not even 767738032Speter checked if you were delivering to anything other than an 767838032Speter IPC-connected host, so a series of (say) local mail 767938032Speter deliveries could cause cached connections to be open 768038032Speter much longer than the specified timeout. 768138032Speter If an incoming message exceeds the maximum message size, stop 768238032Speter writing the incoming bytes to the queue data file, since 768338032Speter this can fill your mqueue partition -- this is a possible 768438032Speter denial-of-service attack. 768538032Speter Don't reject all numeric local user names unless HESIOD is 768638032Speter defined. It turns out that Posix allows all-numeric 768738032Speter user names. Fix from Tony Sanders of BSDI. 768838032Speter Add service switch support. If the local OS has a service 768938032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 769038032Speter on DEC systems) that will be used; otherwise, it falls back 769138032Speter to using a local mechanism based on the ServiceSwitchFile 769238032Speter option (default: /etc/service.switch). For example, if the 769338032Speter service switch lists "files" and "nis" for the aliases 769438032Speter service, that will be the default lookup order. the "files" 769538032Speter ("local" on DEC) service type expands to any alias files 769638032Speter you listed in the configuration file, even if they aren't 769738032Speter actually file lookups. 769838032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 769938032Speter variable which tells whether or not DNS should be considered 770038032Speter canonical. This is now determined based on whether or not 770138032Speter "dns" is in the service list for "hosts". 770238032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 770338032Speter Status Notifications). DSN notifications override 770438032Speter Return-Receipt-To: headers, which are bogus anyhow -- 770538032Speter support for them has been removed. 770638032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 770738032Speter definitions to define the types used in DSN returns for 770838032Speter MTA names, addresses, and diagnostics respectively. 770938032Speter Extend heuristic to force running in ESMTP mode to look for the 771038032Speter five-character string "ESMTP" anywhere in the 220 greeting 771138032Speter message (not just the second line). This is to provide 771238032Speter better compatibility with other ESMTP servers. 771338032Speter Print sequence number of job when running the queue so you can 771438032Speter easily see how much progress you have made. Suggested 771538032Speter by Peter Wemm of DIALix. 771638032Speter Map newlines to spaces in logged message-ids; some versions of 771738032Speter syslog truncate the rest of the line after newlines. 771838032Speter Suggested by Fletcher Mattox of U. Texas. 771938032Speter Move up forking for job runs so that if a message is split into 772038032Speter multiple envelopes you don't get "fork storms" -- this 772138032Speter also improves the connection cache utilization. 772238032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 772338032Speter the purposes of refusing to send error returns. Suggested 772438032Speter by Motonori Nakamura of Ritsumeikan University. 772538032Speter Relax rules on when a file can be written when referenced from 772638032Speter the aliases file: use the default uid/gid instead of the 772738032Speter real uid/gid. This allows you to create a file owned by 772838032Speter and writable only by the default uid/gid that will work 772990792Sgshapiro all the time (without having the set-user-ID bit set). Change 773038032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 773138032Speter Microsystems. 773238032Speter Add "DialDelay" option (no short name) to provide an "extra" 773338032Speter delay for dial on demand systems. If this is non-zero 773438032Speter and a connect fails, sendmail will wait this long and 773538032Speter then try again. If it takes longer than the kernel 773638032Speter timeout interval to establish the connection, this 773738032Speter option can give the network software time to establish 773838032Speter the link. The default units are seconds. 773938032Speter Move logging of sender information to be as early as possible; 774038032Speter previously, it could be delayed a while for SMTP mail 774138032Speter sent to aliases. Suggested by Brad Knowles of the 774238032Speter Defense Information Systems Agency. 774338032Speter Call res_init() before setting RES_DEBUG; this is required by 774438032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 774538032Speter the National Computer Security Center. 774638032Speter Add xdelay= field in logs -- this is a transaction delay, telling 774738032Speter you how long it took to deliver to this address on the 774838032Speter last try. It is intended to be used for sorting mailing 774938032Speter lists to favor "quick" addresses. Provided for use by 775038032Speter the mailprio scripts (see below). 775138032Speter If a map cannot be opened, and that map is non-optional, and 775238032Speter an address requires that map for resolution, queue the 775338032Speter map instead of bouncing it. This involves creating a 775438032Speter pseudo-class of maps called "bogus-map" -- if a required 775538032Speter map cannot be opened, the class is changed to bogus-map; 775638032Speter all queries against bogus-map return "tempfail". The 775738032Speter bogus-map class is not directly accessible. A sample 775838032Speter implementation was donated by Jem Taylor of Glasgow 775938032Speter University Computing Service. 776038032Speter Fix a possible core dump when mailing to a program that talks 776138032Speter SMTP on its standard input. Fix from Keith Moore of 776238032Speter the University of Kentucky. 776338032Speter Make it possible to resolve filenames to $#local $: @ /filename; 776438032Speter previously, the "@" would cause it to not be recognized 776538032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 776638032Speter Accept a -1 signal to re-exec the daemon. This only works if 776738032Speter argv[0] is a full path to sendmail. 776838032Speter Fix bug in "addr=..." field in O option on little-endian machines 776938032Speter -- the network number wasn't being converted to network 777038032Speter byte order. Patch from Kurt Lidl of Pix Technologies 777138032Speter Corporation. 777238032Speter Pre-initialize the resolver early on; this is to avoid a bug with 777338032Speter BIND 4.9.3 that can cause the _res.retry field to get 777438032Speter reset to zero, causing all name server lookups to time 777538032Speter out. Fix from Matt Day of Artisoft. 777638032Speter Restore T line (trusted users) in config file -- but instead of 777738032Speter locking out the -f flag, they just tell whether or not 777838032Speter an X-Authentication-Warning: will be added. This really 777938032Speter just creates new entries in class 't', so "Ft/file/name" 778038032Speter can be used to read trusted user names from a file. 778138032Speter Trusted users are also allowed to execute programs even 778238032Speter if they have a shell that isn't in /etc/shells. 778338032Speter Improve NEWDB alias file rebuilding so it will create them 778438032Speter properly if they do not already exist. This had been 778538032Speter a MAYBENEXTRELEASE feature in 8.6.9. 778638032Speter Check for @:@ entry in NIS maps before starting up to avoid 778738032Speter (but not prevent, sigh) race conditions. This ought to 778838032Speter be handled properly in ypserv, but isn't. Suggested by 778938032Speter Michael Beirne of Motorola. 779038032Speter Refuse connections if there isn't enough space on the filesystem 779138032Speter holding the queue. Contributed by Robert Dana of Wolf 779238032Speter Communications. 779338032Speter Skip checking for directory permissions in the path to a file 779438032Speter when checking for file permissions iff setreuid() 779538032Speter succeeded -- it is unnecessary in that case. This avoids 779638032Speter significant performance problems when looking for .forward 779738032Speter files. Based on a suggestion by Win Bent of USC. 779838032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 779938032Speter arbitrary ruleset number assigned or "Sname = integer" 780038032Speter to assign a specific ruleset number. Reference is 780138032Speter $>name_or_number. Names can be composed of alphas, digits, 780238032Speter underscore, or hyphen (first character must be non-numeric). 780338032Speter Allow -o flag on AliasFile lines to make the alias file optional. 780438032Speter From Bryan Costales of ICSI. 780538032Speter Add NoRecipientAction option to handle the case where there is 780638032Speter no legal recipient header in the message. It can take 780738032Speter on values: 780838032Speter None Leave the message as is. The 780938032Speter message will be passed on even 781038032Speter though it is in technically 781138032Speter illegal syntax. 781238032Speter Add-To Add a To: header with any 781338032Speter recipients that it can find from 781438032Speter the envelope. This risks exposing 781538032Speter Bcc: recipients. 781638032Speter Add-Apparently-To Add an Apparently-To: header. This 781738032Speter has almost no redeeming social value, 781838032Speter and is provided only for back 781938032Speter compatibility. 782038032Speter Add-To-Undisclosed Add a header reading 782138032Speter To: undisclosed-recipients:; 782238032Speter which will have the effect of 782338032Speter making the message legal without 782438032Speter exposing Bcc: recipients. 782538032Speter Add-Bcc To add an empty Bcc: header. 782638032Speter There is a chance that mailers down 782738032Speter the line will delete this header, 782838032Speter which could cause exposure of Bcc: 782938032Speter recipients. 783038032Speter The default is NoRecipientAction=None. 783138032Speter Truncate (rather than delete) Bcc: lines in the header. This 783238032Speter should prevent later sendmails (at least, those that don't 783338032Speter themselves delete Bcc:) from considering this message to 783438032Speter be non-conforming -- although it does imply that non-blind 783538032Speter recipients can see that a Bcc: was sent, albeit not to whom. 783638032Speter Add SafeFileEnvironment option. If declared, files named as delivery 783738032Speter targets must be regular files in addition to the regular 783838032Speter checks. Also, if the option is non-null then it is used as 783938032Speter the name of a directory that is used as a chroot(2) 784038032Speter environment for the delivery; the file names listed in an 784138032Speter alias or forward should include the name of this root. 784238032Speter For example, if you run with 784338032Speter O SafeFileEnvironment=/arch 784438032Speter then aliases should reference "/arch/rest/of/path". If a 784538032Speter value is given, sendmail also won't try to save to 784638032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 784738032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 784838032Speter Support -A flag for alias files; this will comma concatenate like 784938032Speter entries. For example, given the aliases: 785038032Speter list: member1 785138032Speter list: member2 785238032Speter and an alias file declared as: 785338032Speter OAhash:-A /etc/aliases 785438032Speter the final alias inserted will be "list: member1,member2"; 785538032Speter without -A you will get an error on the second and subsequent 785638032Speter alias for "list". Contributed by Bryan Costales of ICSI. 785738032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 785838032Speter Fix a problem that could cause very long addresses to core dump in 785938032Speter some special circumstances. Problem pointed out by Allan 786038032Speter Johannesen. 786138032Speter (Internal change.) Change interface to expand() (macro expansion) 786238032Speter to be simpler and more consistent. 786338032Speter Delete check for funny qf file names. This didn't really give 786438032Speter any extra security and caused some people some problems. 786538032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 786638032Speter at compile time.) Suggested by Kyle Jones of UUNET. 786738032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 786838032Speter merge with DSN code; this is simpler and more consistent. 786938032Speter This may affect some people who have written their own 787038032Speter checkcompat() routine. 787138032Speter (Internal change.) Eliminate `D' line in qf file. The df file 787238032Speter is now assumed to be the same name as the qf file (with 787338032Speter the `q' changed to a `d', of course). 787438032Speter Avoid forking for delivery if all recipient mailers are marked as 787538032Speter "expensive" -- this can be a major cost on some systems. 787638032Speter Essentially, this forces sendmail into "queue only" mode 787738032Speter if all it is going to do is queue anyway. 787838032Speter Avoid sending a null message in some rather unusual circumstances 787938032Speter (specifically, the RCPT command returns a temporary 788038032Speter failure but the connection is lost before the DATA 788138032Speter command). Fix from Scott Hammond of Secure Computing 788238032Speter Corporation. 788338032Speter Change makesendmail to use a somewhat more rational naming scheme: 788438032Speter Makefiles and obj directories are named $os.$rel.$arch, 788538032Speter where $os is the operating system (e.g., SunOS), $rel is 788638032Speter the release number (e.g., 5.3), and $arch is the machine 788738032Speter architecture (e.g., sun4). Any of these can be omitted, 788838032Speter and anything after the first dot in a release number can 788938032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 789038032Speter version used $os.$arch.$rel and was rather less general. 789138032Speter Change makesendmail to do a "make depend" in the target directory 789238032Speter when it is being created. This involves adding an empty 789338032Speter "depend:" entry in most Makefiles. 789438032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 789538032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 789638032Speter of the Finnish Meteorological Institute. 789738032Speter Fix problem that could cause multiple responses to DATA command 789838032Speter on header syntax errors (e.g., lines beginning with colons). 789938032Speter Problem noted by Jens Thomassen of the University of Oslo. 790038032Speter Don't let null bytes in headers cause truncation of the rest of 790138032Speter the header. 790238032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 790338032Speter Increase timeouts on message data puts to allow time for receivers 790438032Speter to canonify addresses in headers on the fly. This is still 790538032Speter a rather ugly heuristic. From Motonori Nakamura. 790638032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 790738032Speter records are not used when canonifying names, and when MX 790838032Speter lookups are done for addressing they must be fully 790938032Speter qualified. This is useful if you have a wildcard MX record, 791038032Speter although it may cause other problems. In general, don't use 791138032Speter wildcard MX records. Patch from Motonori Nakamura. 791238032Speter Eliminate default two-line SMTP greeting message. Instead of 791338032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 791438032Speter is added between the first and second word of the first 791538032Speter line of the greeting message (i.e., immediately after the 791638032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 791738032Speter compile flag. Old sendmails won't see the ESMTP, but that's 791838032Speter acceptable because SIZE was the only useful extension that 791938032Speter old sendmails understand. 792038032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 792138032Speter invoked state dumps. From Masaharu Onishi. 792238032Speter Allow on-line comments in .forward and :include: files; they are 792338032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 792438032Speter is a space or a tab. This is intended for native 792538032Speter representation of non-ASCII sets such as Japanese, where 792638032Speter existing encodings would be unreadable or would lose 792738032Speter data -- for example, 792838032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 792938032Speter (romanized/less information) 793038032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 793138032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 793238032Speter (with MIME encoding, not human readable) 793338032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 793438032Speter (native encoding with ISO-2022-JP) 793538032Speter The last form is human readable in the Japanese environment. 793638032Speter Based on a fix from (surprise!) Motonori Nakamura. 793738032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 793838032Speter messages to that host; these are most frequently associated 793938032Speter with addresses rather than the host, with the exception of 794038032Speter 421 (service shutting down). The effect was to cause queues 794138032Speter to sometimes take an excessive time to flush. Reported by 794238032Speter Robert Sargent of Southern Geographics Technologies and 794338032Speter Eric Prestemon of American University. 794438032Speter Add Nice=N mailer option to set the niceness at which a mailer will 794538032Speter run. This is actually a relative niceness (that is, an 794638032Speter increment on the background value). 794738032Speter Log queue runs that are skipped due to high loads. They are logged 794838032Speter at LOG_INFO priority iff the log level is > 8. Contributed 794938032Speter by Bruce Nagel of Data General. 795038032Speter Allow the error mailer to accept a DSN-style error status code 795138032Speter instead of an sysexits status code in the host part. 795238032Speter Anything with a dot will be interpreted as a DSN-style code. 795338032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 795438032Speter to encode characters that might be munged by an EBCDIC system 795538032Speter in addition to the set required by RFC 1521. The additional 795638032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 795738032Speter (Think of "IBM 360" as the mnemonic for this flag.) 795838032Speter Change check for mailing to files to look for a pathname of [FILE] 795938032Speter rather than looking for the mailer named *file*. The mapping 796038032Speter of leading slashes still goes to the *file* mailer. This 796138032Speter allows you to implement the *file* mailer as a separate 796238032Speter program, for example, to insert a Content-Length: header 796338032Speter or do special security policy. However, note that the usual 796438032Speter initial checking for the file permissions is still done, and 796538032Speter the program in question needs to be very careful about how 796638032Speter it does the file write to avoid security problems. 796738032Speter Be able to read ~root/.forward even if the path isn't accessible to 796838032Speter regular users. This is disrecommended because sendmail 796938032Speter sometimes does not run as root (e.g., when an unsafe option 797038032Speter is specified on the command line), but should otherwise be 797138032Speter safe because .forward files must be owned by the user for 797238032Speter whom mail is being forwarded, and cannot be a symbolic link. 797338032Speter Suggested by Forrest Aldrich of Wang Laboratories. 797438032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 797538032Speter file. This is used for canonifying hostnames when the 797638032Speter service type is "files". 797738032Speter Implement programs on F (read class from file) line. The syntax is 797838032Speter Fc|/path/to/program to read the output from the program 797938032Speter into class "c". 798038032Speter Probe the network interfaces to find alternate names for this 798138032Speter host. Requires the SIOCGIFCONF ioctl call. Code 798238032Speter contributed by SunSoft. 798338032Speter Add "E" configuration line to set or propagate environment 798438032Speter variables into children. "E<envar>" will propagate 798538032Speter the named variable from the environment when sendmail 798638032Speter was invoked into any children it calls; "E<envar>=<value>" 798738032Speter sets the named variable to the indicated value. Any 798838032Speter variables not explicitly named will not be in the child 798938032Speter environment. However, sendmail still forces an 799038032Speter "AGENT=sendmail" environment variable, in part to enforce 799138032Speter at least one environment variable, since many programs and 799238032Speter libraries die horribly if this is not guaranteed. 799338032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 799438032Speter alias databases -- new algorithm looks for the substring 799538032Speter "/yp/" in the file name. This is more portable and involves 799638032Speter less overhead. Suggested by Motonori Nakamura. 799738032Speter Dynamically allocate the queue work list so that you don't lose 799838032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 799938032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 800038032Speter should not need to be changed) and the MaxQueueRunSize option, 800138032Speter which is the absolute maximum number of jobs that will ever 800238032Speter be handled in a single queue run. Based on code contributed 800338032Speter by Brian Coan of the Institute for Global Communications. 800438032Speter Log message when a message is dropped because it exceeds the maximum 800538032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 800638032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 800738032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 800838032Speter of Mark G. Thomas Consulting. 800938032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 801038032Speter OS-dependent defines). The old semantic of -d0.1 to not 801138032Speter run the daemon in background has been moved to -d99.100, 801238032Speter and the old 52.5 flag (to avoid disconnect() from closing 801338032Speter all output files) has been moved to 52.100. This makes 801438032Speter things more consistent (flags below .100 don't change 801538032Speter semantics) and separates out the backgrounding so that 801638032Speter it doesn't happen automatically on other unrelated debugging 801738032Speter flags. 801838032Speter If -t is used but no addresses are found in the header, give an 801938032Speter error message rather than just doing nothing. Fix from 802038032Speter Motonori Nakamura. 802138032Speter On systems (like SunOS) where the effective gid is not necessarily 802238032Speter included in the group list returned by getgroups(), the 802338032Speter `restrictmailq' option could sometimes cause an authorized 802438032Speter user to not be able to use `mailq'. Fix from Charles Hannum 802538032Speter of MIT. 802638032Speter Allow symbolic service names for [IPC] mailers. Suggested by 802738032Speter Gerry Magennis of Logica International. 802838032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 802938032Speter when running DNS. For example, if the name FTP.Foo.ORG is 803038032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 803138032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 803238032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 803338032Speter This is technically illegal under RFC 822 and 1123, but the 803438032Speter IETF is moving toward legalizing it. Note that turning on 803538032Speter this option is not sufficient to guarantee that a downstream 803638032Speter neighbor won't rewrite the address for you. 803738032Speter Add "-m" flag to makesendmail script -- this tells you what object 803838032Speter directory and Makefile it will use, but doesn't actually do 803938032Speter the make. 804038032Speter Do some additional checking on the contents of the qf file to try 804138032Speter to detect attacks against the qf file. In particular, 804238032Speter abort on any line beginning "From ", and add an "end of 804338032Speter file" line -- any data after that line is prohibited. 804438032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 804538032Speter choices. This can be overridden in the Makefile by using 804638032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 804738032Speter (to the extent that we know it) or by defining 804838032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 804938032Speter sendmail 8 to have more consistent installation instructions. 805038032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 805138032Speter of Sun Microsystems. 805238032Speter Improved symbol table hash function from Eric Wassenaar. This one 805338032Speter is at least 50% faster. 805438032Speter Fix problem that didn't notice that timeout on file open was a 805538032Speter transient error. Fix from Larry Parmelee of Cornell 805638032Speter University. 805738032Speter Allow comments (lines beginning with a `#') in files read for 805838032Speter classes. Suggested by Motonori Nakamura. 805938032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 806038032Speter of dropping out entirely. This makes testing some of the 806138032Speter name server lookups easier to deal with when there are 806238032Speter hung servers. From Motonori Nakamura. 806338032Speter Add new ${opMode} macro that is set to the current operation mode 806438032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 806538032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 806638032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 806738032Speter Kind of like queue-only mode (Odq) except it tries to avoid 806838032Speter any external service requests; for dial-on-demand hosts that 806938032Speter want to minimize DNS lookups when mail is being queued. For 807038032Speter this to work you will also have to make sure that gethostbyname 807138032Speter of your local host name does not do a DNS lookup. 807238032Speter Improved handling of "out of space" conditions from John Myers of 807338032Speter Carnegie Mellon. 807438032Speter Improved security for mailing to files on systems that have fchmod(2) 807538032Speter support. 807638032Speter Improve "cannot send message for N days" message -- now says "could 807738032Speter not send for past N days". Suggested by Tom Moore of AT&T 807838032Speter Global Information Solutions. 807938032Speter Less misleading Subject: line on messages sent to postmaster only. 808038032Speter From Motonori Nakamura. 808138032Speter Avoid duplicate error messages on bad command line flags. From 808238032Speter Motonori Nakamura. 808338032Speter Better error message for case where ruleset 0 falls off the end 808438032Speter or otherwise does not resolve to a canonical triple. 808538032Speter Fix a problem that could cause multiple bounce messages if a bad 808638032Speter address was sent along with a good address to an SMTP 808738032Speter site where that SMTP site returned a 4yz code in response 808838032Speter to the final dot of the data. Problem reported by David 808938032Speter James of British Telecom. 809038032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 809138032Speter from Alexander Dupuy of System Management ARTS. 809238032Speter Delete duplicates in MX lists -- believe it or not, there are sites 809338032Speter that list the same host twice in an MX list. This deletion 809438032Speter only works on adjacent preferences, so an MX list that 809538032Speter had A=5, B=10, A=15 would leave both As, but one that had 809638032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 809738032Speter just in case there is something weird I haven't thought of. 809838032Speter Suggested by Barry Shein of Software Tool & Die. 809938032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 819438032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 819538032Speter University of Brno (Czech Republic). 819638032Speter KSR OS 1.2.2 support from Todd Miller of the University 819738032Speter of Colorado. 819838032Speter UX4800 support from Kazuhisa Shimizu of NEC. 819938032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 820038032Speter in type ``btree'' maps. The semantics of this are undefined 820138032Speter for regular maps, but it can be useful for the user database. 820238032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 820338032Speter lookups while the rebuild is going on. There is a race 820438032Speter condition between the open(... O_TRUNC ...) and the lock 820538032Speter on the file, but it should be quite small. 820638032Speter SMRSH: sendmail restricted shell added to the release. This can 820738032Speter be used as an alternative to /bin/sh for the "prog" mailer, 820838032Speter giving the local administrator more control over what 820938032Speter programs can be run from sendmail. 821038032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 821138032Speter part of the release proper, and isn't fully supported; in 821238032Speter particular, it does not run on System V based systems and 821338032Speter never will. 821438032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 821538032Speter to allow rmail to compile on systems that don't have 821638032Speter function prototypes and systems that don't have snprintf. 821738032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 821838032Speter lists by transaction delay times so that addresses that 821938032Speter respond quickly get sent first. This is to prevent very 822038032Speter sluggish servers from delaying other peoples' mail. 822138032Speter Contributed by Tony Sanders of BSDI. 822238032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 822338032Speter of BSDI. This has a lot of comments to help people out. 822438032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 822538032Speter put this on the m4 command line. On GNU m4 (which 822638032Speter supports the __file__ primitive) you can run m4 in an 822738032Speter arbitrary directory -- use either: 822838032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 822938032Speter or 823038032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 823138032Speter On other versions of m4 that don't support __file__, you 823238032Speter can use: 823338032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 823438032Speter (Note the trailing slash on the _CF_DIR_ definition.) 823538032Speter Old versions of m4 will default to _CF_DIR_=.. for back 823638032Speter compatibility. 823738032Speter CONFIG: fix mail from <> so it will properly convert to 823838032Speter MAILER-DAEMON on local addresses. 823938032Speter CONFIG: fix code that was supposed to catch colons in host 824038032Speter names. Problem noted by John Gardiner Myers of CMU. 824138032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 824238032Speter From Paul Riddle of the University of Maryland, Baltimore 824338032Speter County. 824438032Speter CONFIG: Catch and reject "." as a host address. 824538032Speter CONFIG: Generalize domaintable to look up all domains, not 824638032Speter just unqualified ones. 824738032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 824838032Speter was never used and didn't work anyway. 824938032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 825038032Speter and d on all mailers in the UUCP class. 825138032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 825238032Speter look for an alias for "user+detail", then for "user+*", and 825338032Speter finally for "user". This is intended for forwarding mail 825438032Speter for system aliases such as root and postmaster to a 825538032Speter centralized hub. 825638032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 825738032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 825838032Speter The F=8 flag is also set on the "relay" mailer, since 825938032Speter this is expected to be another sendmail. 826038032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 826138032Speter the name of the UUCP_RELAY -- in some cases, this is the 826238032Speter wrong value (e.g., when we have local UUCP connections), 826338032Speter and this can create unreplyable addresses. From Chip 826438032Speter Rosenthal of Unicom. 826538032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 826664562Sgshapiro Received: header inserted into all messages. Suggested by 826738032Speter Gary Mills of the University of Manitoba. 826838032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 826943730Speter to get the old behavior. I did this upon observing 827038032Speter that almost everyone needed this feature, and that the 827138032Speter concept I was trying to make happen didn't work with 827238032Speter some user agents anyway. FEATURE(notsticky) still works, 827338032Speter but it is a no-op. 827438032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 827538032Speter names are sent, rather than immediately diagnosing them 827638032Speter as User Unknown. 827738032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 827838032Speter and RELAY_MAILER_ARGS to set the arguments for the 827938032Speter indicated mailers. All default to "IPC $h". Patch from 828038032Speter Larry Parmelee of Cornell University. 828138032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 828238032Speter on the client side" and F=P to get an appropriate 828338032Speter return-path. From Kimmo Suominen. 828438032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 828538032Speter as the local mailer. For addresses of the form "user+detail" 828638032Speter the "detail" part is passed to procmail via the -a flag. 828738032Speter Contributed by Kimmo Suominen. 828838032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 828938032Speter use from mailertables. This lets you execute arbitrary 829038032Speter procmail scripts. Contributed by Kimmo Suominen. 829138032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 829238032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 829338032Speter Paul Southworth of CICNet Systems Support. 829438032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 829538032Speter This causes the null return path to be rewritten as 829638032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 829738032Speter From Michael Hohmuth of Technische Universitat Dresden. 829838032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 829938032Speter list us as the best possible MX record to be treated as 830038032Speter though they were local (essentially, assume that they 830138032Speter are included in $=w). This can cause additional DNS 830238032Speter traffic, but is easier to administer if this fits your 830338032Speter local model. It does not work reliably if there are 830438032Speter multiple hosts that share the best MX preference. 830538032Speter Code contributed by John Oleynick of Rutgers. 830638032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 830738032Speter SHell) instead of /bin/sh as the program used for delivery 830838032Speter to programs. If an argument is included, it is used as 830938032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 831038032Speter assumed. 831138032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 831238032Speter size of messages to the local and procmail mailers 831338032Speter respectively. Contributed by Brad Knowles of the Defense 831438032Speter Information Systems Agency. 831538032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 831638032Speter (just like text outside of angle brackets) in order to 831738032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 831838032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 831938032Speter any real systems any more) and tweak the DOMAIN macro 832038032Speter so that it is less likely that users will accidentally use 832138032Speter the Berkeley defaults. Also, create some generic files 832238032Speter that really can be used in the real world. 832338032Speter CONFIG: Add new configuration macros to set character sets for 832438032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 832538032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 832638032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 832738032Speter The old name will still be accepted for a while at least. 832838032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 832938032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 833038032Speter As with all relays, it can be ``mailer:hostname''. Suggested 833138032Speter by Scott Hutton. 833238032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 833338032Speter by Barb Dijker of Labyrinth Computer Services. 833438032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 833538032Speter performance for large alias files, and this confused many 833638032Speter people. 833738032Speter CONFIG: Add confCF_VERSION to append local information to the 833838032Speter configuration version number displayed during SMTP startup. 833938032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 834038032Speter would only work when locally addressed. Fix from 834138032Speter Edvard Tuinder of Cistron Internet Services. 834238032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 834343730Speter "n" (CheckAliases) is set when rebuilding alias database. 834438032Speter Based on code contributed by Claude Marinier. 834538032Speter CONFIG: Allow mailertable to have values of the form 834638032Speter ``error:code message''. The ``code'' is a status code 834738032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 834838032Speter Contributed by David James <dwj@agw.bt.co.uk>. 834938032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 835038032Speter sender domains that will be replaced with the masquerade name. 835138032Speter These domains will not be treated as local, but if mail passes 835238032Speter through with sender addresses in those domains they will be 835338032Speter replaced by the masquerade name. These can also be specified 835438032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 835538032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 835638032Speter as well as the header. Substantial improvements to this 835738032Speter code were contributed by Per Hedeland. 835838032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 835938032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 836038032Speter by Kimmo Suominen. 836138032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 836238032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 836338032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 836438032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 836538032Speter UUCP addressing.

This caused UnixWare 850838032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 850938032Speter Novell Labs Europe. 851038032Speter Fix problem with static linking of local getopt routine when 851138032Speter using GNU's ld command. Fix from John Kennedy of 851238032Speter Cal State Chico. 851338032Speter It was possible to turn off privacy flags. Problem noted by 851438032Speter *Hobbit*. 851538032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 851638032Speter and Liudvikas Bukys. 851738032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 851838032Speter from Spider Boardman. 851938032Speter CONFIG: No changes (version number only, to keep it in sync 852038032Speter with the binaries). 852138032Speter 852264562Sgshapiro8.6.10/8.6.10 1995/02/10 852338032Speter SECURITY: Diagnose bogus values to some command line flags that 852438032Speter could allow trash to get into headers and qf files. 852538032Speter Validate the name of the user returned by the IDENT protocol. 852638032Speter Some systems that really dislike IDENT send intentionally 852738032Speter bogus information. Problem pointed out by Michael Bushnell 852838032Speter of the Free Software Foundation. Has some security 852938032Speter implications. 853038032Speter Fix a problem causing error messages about DNS problems when 853138032Speter the host name contained a percent sign to act oddly 853238032Speter because it was passed as a printf-style format string. 853338032Speter In some cases this could cause core dumps. 853438032Speter Avoid possible buffer overrun in returntosender() if error 853538032Speter message is quite long. From Fletcher Mattox of the 853638032Speter University of Texas. 853738032Speter Fix a problem that would silently drop "too many hops" error 853838032Speter messages if and only if you were sending to an alias. 853938032Speter From Jon Giltner of the University of Colorado and 854038032Speter Dan Harton of Oak Ridge National Laboratory. 854138032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 854238032Speter set and e->e_message was null. Fix from Bruce Nagel of 854338032Speter Data General. 854438032Speter Fix problem that can still cause df files to be left around 854538032Speter after "hop count exceeded" messages. Fix from Andrew 854638032Speter Chang and Shau-Ping Lo of SunSoft. 854738032Speter Fix a problem that can cause buffer overflows on very long 854838032Speter user names (as might occur if you piped to a program 854938032Speter with a lot of arguments). 855038032Speter Avoid returning an error and re-queueing if the host signature 855138032Speter is null; this can occur on addresses like ``user@.''. 855238032Speter Problem noted by Wesley Craig and the University of 855338032Speter Michigan. 855438032Speter Avoid possible calls to malloc(0) if MCI caching is turned 855538032Speter off. Bug fix from Pierre David of the Laboratoire 855638032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 855738032Speter Universite de Versailles - St Quentin, and Jacky 855838032Speter Thibault. 855938032Speter Make a local copy of the line being sent via senttolist() -- in 856038032Speter some cases, buffers could get trashed by map lookups 856138032Speter causing it to do unexpected things. This also simplifies 856238032Speter some of the map code. 856338032Speter CONFIG: No changes (version number only, to keep it in sync 856438032Speter with the binaries). 856538032Speter 856664562Sgshapiro8.6.9/8.6.9 1994/04/19 856738032Speter Do all mail delivery completely disconnected from any terminal. 856838032Speter This provides consistency with daemon delivery and 856938032Speter may have some security implications. 857038032Speter Make sure that malloc doesn't get called with zero size, 857138032Speter since that fails on some systems. Reported by Ed 857238032Speter Hill of the University of Iowa. 857338032Speter Fix multi-line values for $e (SMTP greeting message). Reported 857438032Speter by Mike O'Connor of Ford Motor Company. 857538032Speter Avoid syserr if no NIS domain name is defined, but the map it 857638032Speter is trying to open is optional. From Win Bent of USC. 857738032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 857838032Speter Hesiod support for UDB from Todd Miller of the University of 857938032Speter Colorado. Use "hesiod" as the service name in the U 858038032Speter option. 858138032Speter Fix a problem that failed to set the "authentic" host name (that 858238032Speter is, the one derived from the socket info) if you called 858338032Speter sendmail -bs from inetd. Based on code contributed by 858438032Speter Todd Miller (this problem was also reported by Guy Helmer 858538032Speter of Dakota State University). This also fixes a related 858638032Speter problem reported by Liudvikas Bukys of the University of 858738032Speter Rochester. 858838032Speter Parameterize "nroff -h" in all the Makefiles so people with 858938032Speter variant versions can use them easily. Suggested by 859038032Speter Peter Collinson of Hillside Systems. 859138032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 859238032Speter spaces between parameters instead of one. Reported by 859338032Speter Valdis Kletnieks of Virginia Tech. 859438032Speter Reduce the number of system calls during message collection by 859538032Speter using global timeouts around the collect() loop. This 859638032Speter code was contributed by Eric Wassenaar. 859738032Speter If the initial hostname name gathering results in a name 859838032Speter without a dot (usually caused by NIS misconfiguration) 859938032Speter and BIND is compiled in, directly access DNS to get 860038032Speter the canonical name. This should make life easier for 860138032Speter Solaris systems. If it still can't be resolved, and 860238032Speter if the name server is listed as "required", try again 860338032Speter in 30 seconds. If that also fails, exit immediately to 860438032Speter avoid bogus "config error: mail loops back to myself" 860538032Speter messages. 860638032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 860738032Speter message to explain how much space was available and 860838032Speter sound a bit less threatening. Suggested by Stan Janet 860938032Speter of the National Institute of Standards and Technology. 861038032Speter If mail is delivered to an alias that has an owner, deliver any 861138032Speter requested return-receipt immediately, and strip the 861238032Speter Return-Receipt-To: header from the subsequent message. 861338032Speter This prevents a certain class of denial of service 861438032Speter attack, arguably gives more reasonable semantics, and 861538032Speter moves things more towards what will probably become a 861638032Speter network standard. Suggested by Christopher Davis of 861738032Speter Kapor Enterprises. 861838032Speter Add a "noreceipts" privacy flag to turn off all return receipts 861938032Speter without recompiling. 862038032Speter Avoid printing ESMTP parameters as part of the error message 862138032Speter if there are errors during parsing. This change is 862238032Speter purely cosmetic. 862338032Speter Avoid sending out error messages during the collect phase of 862438032Speter SMTP; there is an MVS mailer from UCLA that gets 862538032Speter confused by this. Of course, I think it's their bug.... 862638032Speter Check for the $j macro getting undefined, losing a dot, or getting 862738032Speter lost from $=w in the daemon before accepting a connection; 862838032Speter if it is, it dumps state, prints a LOG_ALERT message, 862938032Speter and drops core for debugging. This is an attempt to 863038032Speter track down a bug that I thought was long since gone. 863138032Speter If you see this, please forward the log fragment to 863238032Speter sendmail@sendmail.ORG. 863338032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 863438032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 863538032Speter Wolfhugel. 863638032Speter Instead of trying to truncate the listen queue for the server 863738032Speter SMTP port when the load average is too high, just close 863838032Speter the port completely and reopen it later as needed. 863938032Speter This ensures that the other end gets a quick "connection 864038032Speter refused" response, and that the connection can be 864138032Speter recovered later. In particular, some socket emulations 864238032Speter seem to get confused if you tweak the listen queue 864338032Speter size around and can never start listening to connections 864438032Speter again. The down side is that someone could start up 864538032Speter another daemon process in the interim, so you could 864638032Speter have multiple daemons all not listening to connections; 864738032Speter this could in turn cause the sendmail.pid file to be 864838032Speter incorrect. A better approach might be to accept the 864938032Speter connection and give a 421 code, but that could break 865043730Speter other mailers in mysterious ways and have paging behavior 865138032Speter implications. 865238032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 865338032Speter set debugging on the wrong socket. From Eric Wassenaar. 865438032Speter When creating a df* temporary file, be sure you truncate any 865538032Speter existing data in the file -- otherwise system crashes 865638032Speter and the like could result in extra data being sent. 865738032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 865838032Speter doc directory. This includes some additional 865938032Speter information. 866038032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 866138032Speter of recipient envelope addresses. This should have been 866238032Speter handled by the $&h trick, but broke if people were 866338032Speter mixing domainized and UUCP addresses. They should 866438032Speter probably have converted all the way over to uucp-uudom 866538032Speter instead of uucp-{new,old}, but the failure mode was to 866638032Speter loop the mail, which was bad news. 866738032Speter Portability fixes: 866838032Speter Newer BSDI systems (several people). 866938032Speter Older BSDI systems from Christophe Wolfhugel. 867038032Speter Intergraph CLIX, from Paul Southworth of CICNet. 867138032Speter UnixWare, from Evan Champion. 867238032Speter NetBSD from Adam Glass. 867338032Speter Solaris from Quentin Campbell of the University of 867438032Speter Newcastle upon Tyne. 867538032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 867638032Speter Corporation. 867738032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 867838032Speter SunOS (it has setsid() and setvbuf() calls) from 867938032Speter Jonathan Kamens of OpenVision Technologies. 868038032Speter HP-UX from Tor Lillqvist. 868138032Speter New Files: 868238032Speter src/Makefile.CLIX 868338032Speter src/Makefile.NCR3000 868438032Speter doc/changes/Makefile 868538032Speter doc/changes/changes.me 868638032Speter doc/changes/changes.ps 868738032Speter 868864562Sgshapiro8.6.8/8.6.6 1994/03/21 868938032Speter SECURITY: it was possible to read any file as root using the 869038032Speter E (error message) option. Reported by Richard Jones; 869138032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 869238032Speter 869364562Sgshapiro8.6.7/8.6.6 1994/03/14 869438032Speter SECURITY: it was possible to get root access by using weird 869538032Speter values to the -d flag. Thanks to Alain Durand of 869638032Speter INRIA for forwarding me the notice from the bugtraq 869738032Speter list. 869838032Speter 869964562Sgshapiro8.6.6/8.6.6 1994/03/13 870038032Speter SECURITY: the ability to give files away on System V-based 870138032Speter systems proved dangerous -- don't run as the owner 870238032Speter of a :include: file on a system that allows giveaways. 870338032Speter Unfortunately, this also applies to determining a 870438032Speter valid shell. 870538032Speter IMPORTANT: Previous versions weren't expiring old connections 870638032Speter in the connection cache for a long time under some 870738032Speter circumstances. This could result in resource exhaustion, 870838032Speter both at your end and at the other end. This checks the 870938032Speter connections for timeouts much more frequently. From 871038032Speter Doug Anderson of NCSC. 871138032Speter Fix a glitch that snuck in that caused programs to be run as 871238032Speter the sender instead of the recipient if the mail was 871338032Speter from a local user to another local user. From 871438032Speter Motonori Nakamura of Kyoto University. 871538032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 871638032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 871738032Speter Bryan Costales of ICSI. 871838032Speter Change the method used to declare the "statfs" availability; 871938032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 872038032Speter tweaking in conf.c, there is a single #define called 872138032Speter SFS_TYPE which takes on one of six values (SFS_NONE 872238032Speter for no statfs availability, SFS_USTAT for the ustat(2) 872338032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 872438032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 872538032Speter statfs(2) call with the declarations in <sys/vfs.h>, 872638032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 872738032Speter Fix glitch in NetInfo support that could return garbage if 872838032Speter there was no "/locations/sendmail" property. From 872938032Speter David Meyer of the University of Virginia. 873038032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 873138032Speter to allow Linux to turn it off even though it is a 873238032Speter BSD-like system. 873338032Speter Allow setting of "ident" timeout to zero to turn off the ident 873438032Speter protocol entirely. 873538032Speter Make 7-bit stripping local to a connection (instead of to a 873638032Speter mailer); this allows you to specify that SMTP is a 873738032Speter 7-bit channel, but revert to 8-bit should it advertise 873838032Speter that it supports 8BITMIME. You still have to specify 873938032Speter mailer flag 7 to get this stripping at all. 874038032Speter Improve makesendmail script so it handles more cases automatically. 874138032Speter Tighten up restrictions on taking ownership of :include: files 874238032Speter to avoid problems on systems that allow you to give away 874338032Speter files. 874438032Speter Fix a problem that made it impossible to rebuild the alias 874538032Speter file if it was on a read-only file system. From 874638032Speter Harry Edmon of the University of Washington. 874738032Speter Improve MX randomization function. From John Gardiner Myers 874838032Speter of CMU. 874938032Speter Fix a minor glitch causing a bogus message to be printed (used 875038032Speter %s instead of %d in a printf string for the line number) 875138032Speter when a bad queue file was read. From Harry Edmon. 875238032Speter Allow $s to remain NULL on locally generated mail. I'm not 875338032Speter sure this is necessary, but a lot of people have complained 875438032Speter about it, and there is a legitimate question as to whether 875538032Speter "localhost" is legal as an 822-style domain. 875638032Speter Fix a problem with very short line lengths (mailer L= flag) in 875738032Speter headers. This causes a leading space to be added onto 875838032Speter continuation lines (including in the body!), and also 875938032Speter tries to wrap headers containing addresses (From:, To:, 876038032Speter etc) intelligently at the shorter line lengths. Problem 876138032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 876238032Speter Log the real user name when logging syserrs, since these can have 876338032Speter security implications. Suggested by several people. 876438032Speter Fix address logging of cached connections -- it used to always 876538032Speter log the numeric address as zero. This is a somewhat 876638032Speter bogus implementation in that it does an extra system 876738032Speter call, but it should be an inexpensive one. Fix from 876838032Speter Motonori Nakamura. 876938032Speter Tighten up handling of short syslog buffers even more -- there 877038032Speter were cases where the outgoing relay= name was too long 877138032Speter to share a line with delay= and mailer= logging. 877238032Speter Limit the overhead on split envelopes to one open file descriptor 877338032Speter per envelope -- previously the overhead was three 877438032Speter descriptors. This was in response to a problem reported 877538032Speter by P{r (Pell) Emanuelsson. 877638032Speter Fixes to better handle the case of unexpected connection closes; 877738032Speter this redirects the output to the transcript so the info 877838032Speter is not lost. From Eric Wassenaar. 877938032Speter Fix potential string overrun if you macro evaluate a string that 878038032Speter has a naked $ at the end. Problem noted by James Matheson 878138032Speter <jmrm@eng.cam.ac.uk>. 878238032Speter Make default error number on $#error messages 553 (``Requested 878338032Speter action not taken: mailbox name not allowed'') instead of 878438032Speter 501 (``Syntax error in parameters or arguments'') to 878538032Speter avoid bogus "protocol error" messages. 878638032Speter Strip off any existing trailing dot on names during $[ ... $] 878738032Speter lookup. This prevents it from ending up with two dots 878838032Speter on the end of dot terminated names. From Wesley Craig 878938032Speter of the University of Michigan and Bryan Costales of ICSI. 879038032Speter Clean up file class reading so that the debugging information is 879138032Speter more informative. It hadn't been using setclass, so you 879238032Speter didn't see the class items being added. 879338032Speter Avoid core dump if you are running a version of sendmail where 879438032Speter NIS is compiled in, and you specify an NIS map, but 879538032Speter NIS is not running. Fix from John Oleynick of 879638032Speter Rutgers. 879738032Speter Diagnose bizarre case where res_search returns a failure value, 879838032Speter but sets h_errno to a success value. 879938032Speter Make sure that "too many hops" messages are considered important 880038032Speter enough to send an error to the Postmaster (that is, the 880138032Speter address specified in the P option). This fix should 880238032Speter help problems that cause the df file to be left around 880338032Speter sometimes -- unfortunately, I can't seem to reproduce 880438032Speter the problem myself. 880538032Speter Avoid core dump (null pointer reference) on EXPN command; this 880638032Speter only occurred if your log level was set to 10 or higher 880738032Speter and the target account was an alias or had a .forward file. 880838032Speter Problem noted by Janne Himanka. 880938032Speter Avoid "denial of service" attacks by someone who is flooding your 881038032Speter SMTP port with bad commands by shutting the connection 881138032Speter after 25 bad commands are issued. From Kyle Jones of 881238032Speter UUNET. 881338032Speter Fix core dump on error messages with very long "to" buffers; 881438032Speter fmtmsg overflows the message buffer. Fixed by trimming 881538032Speter the to address to 203 characters. Problem reported by 881638032Speter John Oleynick. 881738032Speter Fix configuration for HASFLOCK -- there were some spots where 881838032Speter a #ifndef was incorrectly #ifdef. Pointed out by 881938032Speter George Baltz of the University of Maryland. 882038032Speter Fix a typo in savemail() that could cause the error message To: 882138032Speter lists to be incorrect in some places. From Motonori 882238032Speter Nakamura. 882338032Speter Fix a glitch that can cause duplicate error messages on split 882438032Speter envelopes where an address on one of the lists has a 882538032Speter name server failure. Fix from Voradesh Yenbut of the 882638032Speter University of Washington. 882738032Speter Fix possible bogus pointer reference on ESMTP parameters that 882838032Speter don't have an ``=value'' part. 882938032Speter CNAME loops caused an error message to be generated, but also 883038032Speter re-queued the message. Changed to just re-queue the 883138032Speter message (it's really hard to just bounce it because 883238032Speter of the weird way the name server works in the presence 883338032Speter of CNAME loops). Problem noted by James M.R.Matheson 883438032Speter of Cambridge University. 883538032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 883638032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 883738032Speter user name. Suggested by Andreas Stolcke of ICSI. 883838032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 883938032Speter override it easily in the Makefile -- that is, you can 884038032Speter turn it off using -DNAMED_BIND=0. 884138032Speter If a gethostbyname(...) of an address with a trailing dot fails, 884238032Speter try it without the trailing dot. This is because if 884338032Speter you have a version of gethostbyname() that falls back 884438032Speter to NIS or the /etc/hosts file it will fail to find 884538032Speter perfectly reasonable names that just don't happen to 884638032Speter be dot terminated in the hosts file. You don't want to 884738032Speter strip the dot first though because we're trying to ensure 884838032Speter that country names that match one of your subdomains get 884938032Speter a chance. 885038032Speter PRALIASES: fix bogus output on non-null-terminated strings. 885138032Speter From Bill Gianopoulos of Raytheon. 885238032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 885338032Speter This was in code intended to only catch the self-literal 885438032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 885538032Speter IP address), but the code was broken. However, it will 885638032Speter still do this if $M is defined; this is necessary to 885738032Speter get client configurations to work (sigh). Note that this 885838032Speter means that $M overrides :mailname entries in the user 885938032Speter database! Problem noted by Paul Southworth. 886038032Speter CONFIG: Fix definition of Solaris help file location. From 886138032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 886238032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 886338032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 886438032Speter and USENET_MAILER_MAX to tweak the maximum message 886538032Speter size for various mailers. 886638032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 886738032Speter instead of assuming that it is "inews" for consistency 886838032Speter with other mailers. From Michael Corrigan of UC San Diego. 886938032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 887038032Speter qualify the address in the SMTP envelope as user@{relay|hub} 887138032Speter instead of user@$j. From Bill Wisner of The Well. 887238032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 887338032Speter CONFIG: Don't turn off case mapping of user names in the local 887438032Speter mailer for IRIX. This was different than most every other 887538032Speter system. 887638032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 887738032Speter envelope. Noted by Thierry Besancon 887838032Speter <besancon@excalibur.ens.fr>. 887938032Speter CONFIG: Don't include -z by default on uux line -- most systems 888038032Speter don't want it set by default. Pointed out by Philippe 888138032Speter Michel of Thomson CSF. 888238032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 888338032Speter host name was foo.bar.ray.com and you matched against 888438032Speter ".ray.com", the old implementation bound %1 to "bar" 888538032Speter instead of "foo.bar". Also, allow "." in the mailertable 888638032Speter to match anything -- essentially, take over SMART_HOST. 888738032Speter This also moves matching of explicit local host names 888838032Speter before the mailertable so they don't have to be special 888938032Speter cased in the mailertable data. Reported by Bill 889038032Speter Gianopoulos of Raytheon; the fix for the %1 binding 889138032Speter problem was contributed by Nicholas Comanos of the 889238032Speter University of Sydney. 889338032Speter CONFIG: Don't include "root" in class $=L (users to deliver 889438032Speter locally, even if a hub or relay exists) by default. 889538032Speter This is because of the known bug where definition of 889638032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 889738032Speter both and deliver into the local mailbox. 889838032Speter CONFIG: Move up bitdomain and uudomain handling so that they 889938032Speter are done before .UUCP class matching; uudomain was 890038032Speter reported as ineffective before. This also frees up 890138032Speter diversion 8 for future use. Problem reported by Kimmo 890238032Speter Suominen. 890338032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 890438032Speter into host names. As pointed out by Jonathan Kamens, 890538032Speter these are often used because either the forward or reverse 890638032Speter mapping is broken; this translation makes it broken again. 890738032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 890838032Speter Suominen. 890938032Speter Portability fixes: 891038032Speter Unicos from David L.

From 893438032Speter Bob Campbell at U.C. Berkeley. 893538032Speter Security fix: group ids were not completely set when programs 893638032Speter were invoked. This caused programs to have group 893738032Speter permissions they should not have had (usually group 893838032Speter daemon instead of their own group). In particular, 893938032Speter Perl scripts would refuse to run. 894038032Speter Security: check to make sure files that are written are not 894138032Speter symbolic links (at least under some circumstances). 894238032Speter Although this does not respond to a specific known 894338032Speter attack, it's just a good idea. Suggested by 894438032Speter Christian Wettergren. 894538032Speter Security fix: if a user had an NFS mounted home directory on 894638032Speter a system with a restricted shell listed in their 894738032Speter /etc/passwd entry, they could still execute any 894838032Speter program by putting that in their .forward file. 894938032Speter This fix prevents that by insisting that their shell 895038032Speter appear in /etc/shells before allowing a .forward to 895138032Speter execute a program or write a file. You can disable 895238032Speter this by putting "*" in /etc/shells. It also won't 895338032Speter permit world-writable :include: files to reference 895438032Speter programs or files (there's no way to disable this). 895543730Speter These behaviors are only one level deep -- for 895638032Speter example, it is legal for a world-writable :include: 895738032Speter file to reference an alias that writes a file, on 895838032Speter the assumption that the alias file is well controlled. 895938032Speter Security fix: root was not treated suspiciously enough when 896038032Speter looking into subdirectories. This would potentially 896138032Speter allow a cracker to examine files that were publicly 896238032Speter readable but in a non-publicly searchable directory. 896338032Speter Fix a problem that causes an error on QUIT on a cached 896438032Speter connection to create problems on the current job. 896538032Speter These are typically unrelated, so errors occur in 896638032Speter the wrong place. 896738032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 896838032Speter runs more responsive to load average, and fixes a 896938032Speter problem that ignored the load average in locally 897038032Speter generated mail. From Eric Wassenaar. 897138032Speter Fix possible core dump on aliases with null LHS. From 897238032Speter John Orthoefer of BB&N. 897338032Speter Revert to using flock() whenever possible -- there are just 897438032Speter too many bugs in fcntl() locking, particularly over 897538032Speter NFS, that cause sendmail to fail in perverse ways. 897638032Speter Fix a bug that causes the connection cache to get confused 897738032Speter when sending error messages. This resulted in 897838032Speter "unexpected close" messages. It should fix itself 897938032Speter on the following queue run. Problem noted by 898038032Speter Liudvikas Bukys of the University of Rochester. 898138032Speter Include $k in $=k as documented in the Install & Op Guide. 898238032Speter This seems odd, but it was documented.... From 898338032Speter Michael Corrigan of UCSD. 898438032Speter Fix problem that caused :include:s from alias files to be 898538032Speter forced to be owned by root instead of daemon 898638032Speter (actually DefUid). From Tim Irvin. 898738032Speter Diagnose unrecognized I option values -- from Mortin Forssen 898838032Speter of the Chalmers University of Technology. 898938032Speter Make "error" mailer work consistently when there is no error 899038032Speter code associated with it -- previously it returned OK 899138032Speter even though there was a real problem. Now it assumes 899238032Speter EX_UNAVAILABLE. 899338032Speter Fix bug that caused the last header line of messages that had 899438032Speter no body and which were terminated with EOF instead of 899538032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 899638032Speter Fix core dump on SMTP mail to programs that failed -- it tried 899738032Speter to go to a "next MX host" when none existed, causing 899838032Speter a core dump. From der Mouse at McGill University. 899938032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 900038032Speter this makes it easier to turn it off (using 900138032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 900238032Speter Fix YP_MASTER_NAME store to use the unupdated result of 900338032Speter gethostname() (instead of myhostname(), which tries 900438032Speter to fully qualify the name) to be consistent with 900538032Speter SunOS. If your hostname is unqualified, this fixes 900638032Speter transfers to slave servers. Bug noted by Keith 900738032Speter McMillan of Ameritech Services, Inc. 900838032Speter Fix Ultrix problem: gethostbyname() can return a very large 900938032Speter (> 500) h_length field, which causes the sockaddr 901038032Speter to be trashed. Use the size of the sockaddr instead. 901138032Speter Fix from Bob Manson of Ohio State. 901238032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 901338032Speter defined -- this confuses gethostbyname on hosts 901438032Speter file lookups, which doesn't understand the trailing 901538032Speter dot convention. 901638032Speter Log SMTP server subprocesses that die with a signal instead 901738032Speter of from a clean exit. 901838032Speter If you don't have option "I" set, don't assume that a DNS 901938032Speter "host unknown" message is authoritative -- it 902038032Speter might still be found in /etc/hosts. 902138032Speter Fix a problem that would cause Deferred: messages to be sent 902238032Speter as the subject of an error message, even though the 902338032Speter actual cause of a message was more severe than that. 902438032Speter Problem noted by Chris Seabrook of OSSI. 902538032Speter Fix race condition in DBM alias file locking. From Kyle 902638032Speter Jones of UUNET. 902738032Speter Limit delivery syslog line length to avoid bugs in some 902838032Speter versions of syslog(3). This adds a new compile time 902938032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 903038032Speter University, which is in turn derived from IDA. 903138032Speter Fix quotes inside of comments in addresses -- previously 903238032Speter it insisted that they be balanced, but the 822 spec 903338032Speter says that they should be ignored. 903438032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 903538032Speter debugging). This also evaluates ruleset 89, if set 903638032Speter (with the null input), and logs the result. This 903738032Speter should be used sparingly, since the rewrite process 903838032Speter is not reentrant. 903938032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 904038032Speter documented in the Bat Book. 904138032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 904238032Speter return an error message and did not requeue the message. 904338032Speter Fix based on code from Roland Dirlewanger of 904438032Speter Reseau Regional Aquarel, Bordeaux, France. 904538032Speter Fix a problem that caused a seg fault if you got a 421 error 904638032Speter code during some parts of connection initialization. 904738032Speter I've only seen this when talking to buggy mailers on 904838032Speter the other end, but it shouldn't give a seg fault in 904938032Speter any case.

Noted by William C Fenner of 909138032Speter the NRL Connection Machine Facility. 909238032Speter Fix a problem that could cause a core dump if the input sequence 909338032Speter had (or somehow acquired) a \231 character. 909438032Speter Make sure that route-addrs always have <angle brackets> around 909538032Speter them in non-SMTP envelopes (SMTP envelopes already do 909638032Speter this properly). 909738032Speter Avoid weird headers on unbalanced punctuation of the form: 909838032Speter ``Joe User <user)'' -- this caused reference to the 909938032Speter null macro. Fix from Rick McCarty of IO.COM. 910038032Speter Fix a problem that caused an alias "user: user@local.host" to 910138032Speter not have the QNOTREMOTE bit set; this caused configs 910238032Speter to act as if FEATURE(notsticky) was defined even when 910338032Speter it was not. The effect of the problem was to make it 910438032Speter very hard to to set up satellite sites that had a few 910538032Speter local accounts, with everything else forwarded to a 910638032Speter corporate hub. Reported by Detlef Drewanz of the 910738032Speter University of Rostock and Mark Frost of NCD. 910838032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 910938032Speter addresses. This is more efficient (fewer name server 911038032Speter calls) and fixes certain unusual configurations, such 911138032Speter as those that have ruleset 4 do something that is 911238032Speter non-idempotent unless a mailer-specific ruleset did 911338032Speter something else.

Briefly, if you are sending to host 918238032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 918338032Speter "foo!baz" remains "foo!baz", and anything else has 918438032Speter the local name prepended. 918538032Speter CONFIG: portability fixes for HP-UX. 918638032Speter DOC: several minor problems fixed in the Install & Op Guide. 918738032Speter MAKEMAP: fix core dump problem on lines that are too long or 918838032Speter which lack newline. From Mark Delany. 918938032Speter MAILSTATS: print sums of columns (total messages & kbytes 919038032Speter in and out of the system). From Tom Ferrin of UC 919138032Speter San Francisco Computer Graphics Lab. 919238032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 919338032Speter On HP-UX, /etc/sendmail.cf has been moved to 919438032Speter /usr/lib/sendmail.cf to match HP sendmail. 919538032Speter Permissions have been tightened up on world-writable 919638032Speter :include: files and accounts that have shells 919738032Speter that are not listed in /etc/shells. This may 919838032Speter cause some .forward files that have worked 919938032Speter before to start failing. 920038032Speter SIGUSR1 dumps some state to the log. 920138032Speter NEW FILES: 920238032Speter src/Makefile.DGUX 920338032Speter src/Makefile.Dynix 920438032Speter src/Makefile.FreeBSD 920538032Speter src/Makefile.Mach386 920638032Speter src/Makefile.NetBSD 920738032Speter src/Makefile.RISCos 920838032Speter src/Makefile.SCO 920938032Speter src/Makefile.SVR4 921038032Speter src/Makefile.Titan 921138032Speter cf/mailer/pop.m4 921238032Speter cf/ostype/bsdi1.0.m4 921338032Speter cf/ostype/dgux.m4 921438032Speter cf/ostype/dynix3.2.m4 921538032Speter cf/ostype/sco3.2.m4 921638032Speter makemap/Makefile.dist 921738032Speter praliases/Makefile.dist 921838032Speter 921964562Sgshapiro8.6.4/8.6.4 1993/10/31 922038032Speter Repair core-dump problem (write to read-only memory segment) 922138032Speter if you fall back to the return-to-Postmaster case in 922238032Speter savemail. Problem reported by Richard Liu. 922338032Speter Immediately diagnose bogus sender addresses in SMTP. This 922438032Speter makes quite certain that crackers can't use this 922538032Speter class of attack. 922638032Speter Reliability Fix: check return value from fclose() and fsync() 922738032Speter in a few critical places. 922838032Speter Minor problem in initsys() that reversed a condition for 922938032Speter redirecting the output channel on queue runs. It's 923038032Speter not clear this code even does anything. From Eric 923138032Speter Wassenaar of the Dutch National Institute for Nuclear 923238032Speter and High-Energy Physics. 923338032Speter Fix some problems that caused queue runs to do "too much work", 923438032Speter such as double-reading the Errors-To: header. From 923538032Speter Eric Wassenaar. 923638032Speter Error messages on writing the temporary file (including the 923738032Speter data file) were getting suppressed in SMTP -- this 923838032Speter fix causes them to be properly reported. From Eric 923938032Speter Wassenaar. 924038032Speter Some changes to support AF_UNIX sockets -- this will only 924138032Speter really become relevant in the next release, but some 924238032Speter people need it for local patches. From Michael 924338032Speter Corrigan of UC San Diego. 924438032Speter Use dynamically allocated memory (instead of static buffers) 924538032Speter for macros defined in initsys() and settime(); since 924638032Speter these can have different values depending on which 924738032Speter envelope they are in. From Eric Wassenaar. 924838032Speter Improve logging to show ctladdr on to= logging; this tells you 924938032Speter what uid/gid processes ran as. 925038032Speter Fix a problem that caused error messages to be discarded if 925138032Speter the sender address was unparseable for some reason; 925238032Speter this was supposed to fall back to the "return to 925338032Speter postmaster" case. 925438032Speter Improve aliaswait backoff algorithm. 925538032Speter Portability patches for Linux (8.6.3 required another header 925638032Speter file) (from Karl London) and SCO UNIX. 925738032Speter CONFIG: patch prog mailer to not strip host name off of envelope 925838032Speter addresses (so that it matches local again). From 925938032Speter Christopher Davis. 926038032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 926138032Speter this prevents uux from seeing lines with null names like 926238032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 926338032Speter Nakamura of Kyoto University. 926438032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 926538032Speter it shouldn't fail miserably. From Motonori Nakamura. 926638032Speter 926764562Sgshapiro8.6.2/8.6.2 1993/10/15 926838032Speter Put a "successful delivery" message in the transcript for 926938032Speter addresses that get return-receipts. 927038032Speter Put a prominent "this is only a warning" message in warning 927138032Speter messages -- some people don't read carefully enough 927238032Speter and end up sending the message several times. 927338032Speter Include reason for temporary failure in the "warning" return 927438032Speter message. Currently, it just says "cannot send for 927538032Speter four hours". 927638032Speter Fix the "Original message received" time generated for 927738032Speter returntosender messages. It was previously listed as 927838032Speter the current time. Bug reported by Eric Hagberg of 927938032Speter Cornell University Medical College. 928038032Speter If there is an error when writing the body of a message, 928138032Speter don't send the trailing dot and wait for a response 928238032Speter in sender SMTP, as this could cause the connection to 928338032Speter hang up under some bizarre circumstances. From Eric 928438032Speter Wassenaar. 928538032Speter Fix some server SMTP synchronization problems caused when 928638032Speter connections fail during message collection. From 928738032Speter Eric Wassenaar. 928838032Speter Fix a problem that can cause srvrsmtp to reject mail if the 928938032Speter name server is down -- it accepts the RCPT but rejects 929038032Speter the DATA command. Problem reported by Jim Murray of 929138032Speter Stratus. 929238032Speter Fix a problem that can cause core dumps if the config file 929338032Speter incorrectly resolves to a null hostname. Reported by 929438032Speter Allan Johannesen of WPI. 929538032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 929638032Speter by non-root users were not put into 929738032Speter X-Authentication-Warning:s as intended because the 929843730Speter config file hadn't set the PrivacyOptions yet. Fix 929938032Speter from Sven-Ove Westberg of the University of Lulea. 930038032Speter Under very odd circumstances, the alias file rebuild code 930138032Speter could get confused as to whether a database was 930238032Speter open or not. 930338032Speter Check "vendor code" on the end of V lines -- this is 930438032Speter intended to provide a hook for vendor-specific 930538032Speter configuration syntax. (This is a "new feature", 930638032Speter but I've made an exception to my rule in a belief 930738032Speter that this is a highly exceptional case.) 930838032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 930938032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 931038032Speter (from Jon Forrest of UC Berkeley) 931138032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 931238032Speter 931364562Sgshapiro8.6.1/8.6 1993/10/08 931438032Speter Portability fixes for A/UX and Encore UMAX V. 931538032Speter Fix error message handling -- if you had a name server down 931638032Speter causing an error during parsing, that message was never 931738032Speter propagated to the queue file. 931838032Speter 931964562Sgshapiro8.6/8.6 1993/10/05 932038032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 932138032Speter conf.h (other systems have the same bug). 932238032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 932338032Speter getdtablesize() instead of sysconf(); a disturbingly 932438032Speter large number of systems defined _SC_OPEN_MAX in the 932538032Speter header files but don't have the syscall. 932638032Speter Another patch to really truly ignore MX records in getcanonname 932738032Speter if trymx == FALSE. 932838032Speter Fix problem that caused the "250 IAA25499 Message accepted for 932938032Speter delivery" message to be omitted if there was an error 933038032Speter in the header of the message (e.g., a bad Errors-To: 933138032Speter line). Pointed out by Michael Corrigan of UCSD. 933238032Speter Announce name of host we are chatting when we get errors; this 933338032Speter is an IDA-ism suggested by Christophe Wolfhugel. 933438032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 933538032Speter Australian Artificial Intelligence Institute), SCO Unix 933638032Speter (from Murray Kucherawy of Hookup Communication Corp.), 933738032Speter NeXT (from Vince DeMarco and myself), Linux (from 933838032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 933938032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 934038032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 934138032Speter Some changes to get around gcc optimizer bugs. From Takahiro 934238032Speter Kanbe. 934338032Speter Fix error recovery in queueup if another tf file of the same 934438032Speter name already exists. Problem stumbled over by Bill 934538032Speter Wisner of The Well. 934638032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 934738032Speter Problem noted by Keith McMillan of Ameritech Services. 934838032Speter Deal with group permissions properly when opening .forward and 934938032Speter :include: files. This relaxes the 8.1C restrictions 935038032Speter slightly more. This includes proper setting of groups 935138032Speter when reading :include: files, allowing you to read some 935238032Speter files that you should be able to read but have previously 935338032Speter been denied unless you owned them or they had "other" 935438032Speter read permission. 935538032Speter Make certain that $j is in $=w (after the .cf is read) so that 935638032Speter if the user is forced to override some silly system, 935738032Speter MX suppression will still work. 935838032Speter Fix a couple of efficiency problems where newstr was double- 935938032Speter calling expensive routines. In at least one case, it 936038032Speter wasn't guaranteed that they would always return the 936138032Speter same result. Problem noted by Christophe Wolfhugel. 936238032Speter Fix null pointer dereference in putoutmsg -- only on an error 936338032Speter condition from a non-SMTP mailer. From Motonori 936438032Speter Nakamura. 936538032Speter Macro expand "C" line class definitions before scanning so that 936638032Speter "CX $Z" works. 936738032Speter Fix problem that caused error message to be sent while still 936838032Speter trying to send the original message if the connection 936938032Speter is closed during a DATA command after getting an error 937038032Speter on an RCPT command (pretty obscure). Problem reported 937138032Speter by John Myers of CMU. 937238032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 937338032Speter term bug. 937438032Speter Fix a nasty bug causing core dumps when returning the "warning: 937538032Speter cannot deliver for N hours -- will keep trying" message; 937643730Speter it only occurred if you had PostmasterCopy set and 937738032Speter only on some architectures. Although sendmail would 937838032Speter keep trying, it would send error messages on each 937938032Speter queue interval. This is an important fix. 938038032Speter Allow u and g options to take user and group names respectively. 938138032Speter Don't do a chdir into the queue directory in -bt mode to make 938238032Speter ruleset testing a bit easier. 938338032Speter Don't allow users to turn off logging (using -oL) on the command 938438032Speter line -- command line can only raise, not lower, logging 938538032Speter level. 938638032Speter Set $u to the original recipient on the SMTP transaction or on 938738032Speter the command line. This is only done if there is exactly 938838032Speter one recipient. Technically, this does not meet the 938938032Speter specs, because it does not guarantee a domain on the 939038032Speter address. 939138032Speter Fix a problem that dumped error messages on bad addresses if 939238032Speter you used the -t flag. Problem noted by Josh Smith of 939338032Speter Harvey Mudd College. 939438032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 939538032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 939638032Speter avoid the problem of people who use angle brackets in 939738032Speter their full name information. 939838032Speter Fix a null pointer dereference if you set option "l", have 939938032Speter an Errors-To: header in the message, and have Errors-To: 940038032Speter defined in the config file H lines. From J.R. Oldroyd. 940138032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 940238032Speter wrong when compiling. Suggested by Rick McCarty of TI. 940338032Speter Fix a problem that could pass negative SIZE parameter if the 940438032Speter df file got lost; this would cause servers to always 940538032Speter give a temporary failure, making the problem even worse. 940638032Speter Problem noted by Allan Johannesen of WPI. 940738032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 940838032Speter protocol timeouts (30s default). Requested by Murray 940938032Speter Kucherawy of HookUp Communication Corp. to handle bogus 941038032Speter PC TCP/IP implementations. 941138032Speter Change $w default definition to be just the first component of 941238032Speter the domain name on config level 5. The $j macro defaults 941338032Speter to the FQDN; $m remains as before. This lets well-behaved 941438032Speter config files use any of the short, long, or subdomain 941538032Speter names. 941638032Speter Add makesendmail script in src to try to automate multi-architecture 941738032Speter builds. I know, this is sub-optimal, but it is still 941838032Speter helpful. 941938032Speter Fix very obscure race condition that can cause a queue run to 942038032Speter get a queue file for an already completed job. This 942138032Speter problem has existed for years. Problem noted by the 942238032Speter long suffering Allan Johannesen of WPI. 942338032Speter Fix a problem that caused the raw sender name to be passed to 942438032Speter udbsender instead of the canonified name -- this caused 942538032Speter it to sometimes miss records that it should have found. 942638032Speter Relax check of name on HELO packet so that a program using -bs 942738032Speter that claims to be itself works properly. 942838032Speter Restore rewriting of $: part of address through 2, R, 4 in 942938032Speter buildaddr -- this requires passing a lot of flags to get 943038032Speter it right. Unlike old versions, this ONLY rewrites 943138032Speter recipient addresses, not sender addresses. 943238032Speter Fix a bug that caused core dumps in config files that cannot 943338032Speter resolve /file/name style addresses. Fix from Jonathan 943438032Speter Kamens of OpenVision Technologies. 943538032Speter Fix problem with fcntl locking that can cause error returns to 943638032Speter be lost if the lock is lost; this required fully 943738032Speter queueing everything, dropping the envelope (so errors 943838032Speter would get returned), and then re-reading the queue from 943938032Speter scratch. 944038032Speter Fix a problem that caused aliases that redefine an otherwise 944138032Speter true address to still send to the original address 944238032Speter if and only if the alias failed in certain bizarre 944338032Speter ways (e.g, if they pointed at a list:; syntax address). 944438032Speter Problem pointed out by Jonathan Kamens. 944538032Speter Remove support for frozen configuration files. They caused 944638032Speter more trouble than it was worth. 944738032Speter Fix problem that can cause error messages to get ignored when 944838032Speter using both -odb and -t flags. Problem noted by Rob 944938032Speter McNicholas at U.C. Berkeley. 945038032Speter Include all "normal" variations on hostname in $=w. For example, 945138032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 945238032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 945338032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 945438032Speter the queue. 945538032Speter Reset SmtpPhase global on initial connection creation so that 945638032Speter messages don't come out with stale information. 945738032Speter Pass an "ext" argument to lockfile so that error/log messages 945838032Speter will properly reflect the true filename being locked. 945938032Speter Put all [...] address forms into $=w -- this eliminates the need 946038032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 946138032Speter Myers of CMU. 946238032Speter Fix a bug that can cause qf files to be left around even after 946338032Speter an SMTP RSET command. Problem and fix from Michael 946438032Speter Corrigan. 946543730Speter Don't send a PostmasterCopy to errors when the Precedence: is 946638032Speter negative. Error reports still go to the envelope 946738032Speter sender address. 946838032Speter Add LA_SHORT for load averages. 946938032Speter Lock sendmail.st file when posting statistics. 947038032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 947138032Speter set the size of the TCP send and receive buffers; if you 947238032Speter run over a slow slip line you may need to set these down 947338032Speter (although it would be better to fix the SLIP implementation 947438032Speter so that it's not necessary to recompile every program 947538032Speter that does bulk data transfer). 947638032Speter Allow null defaults on $( ... $) lookups. Problem reported by 947738032Speter Amir Plivatsky. 947838032Speter Diagnose crufty S and V config lines. This resulted from an 947938032Speter observation that some people were using the SITE macro 948038032Speter without the SITECONFIG macro first, which was causing 948138032Speter bogus config files that were not caught. 948238032Speter Fix makemap -f flag to turn off case folding (it was turning it 948338032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 948438032Speter Fix a problem that caused multiple error messages to be sent if 948538032Speter you used "sendmail -t -oem -odb", your system uses fcntl 948638032Speter locking, and one of the recipient addresses is unknown. 948738032Speter Reset uid earlier in include() so that recursive .forwards or 948838032Speter :include:s don't use the wrong uid. 948938032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 949038032Speter called, the code to recover the descriptor was broken. 949138032Speter This sometimes (only sometimes) caused problems with the 949238032Speter alias file. Fix from Motonori Nakamura. 949338032Speter Fix a problem that caused aliaswait to go into infinite recursion 949438032Speter if the @:@ metasymbol wasn't found in the alias file. 949538032Speter Improve error message on newaliases if database files cannot be 949638032Speter opened or if running with no database format defined. 949738032Speter Do a better estimation of the size of error messages when NoReturn 949838032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 949938032Speter Fix a problem causing the "c" option (don't connect to expensive 950038032Speter mailers) to be ignored in SMTP. Problem noted and the 950138032Speter solution suggested by Robert Elz of The University of 950238032Speter Melbourne. 950338032Speter Improve connection caching algorithm by passing "[host]" to 950438032Speter hostsignature, which strips the square brackets and 950538032Speter returns the real name. This allows mailertable entries 950638032Speter to match regular entries. 950738032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 950838032Speter feature, even if it doesn't work right. 950938032Speter Catch and log attempts to try the "wiz" command in server SMTP. 951038032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 951138032Speter Be more generous at assigning $z to the home directory -- do this 951238032Speter for programs that are specified through a .forward file. 951338032Speter Fix from Andrew Chang of Sun Microsystems. 951438032Speter Always save a fatal error message in preference to a non-fatal 951538032Speter error message so that the "subject" line of return 951638032Speter messages is the best possible. 951738032Speter CONFIG: reduce the number of quotes needed to quote configuration 951838032Speter parameters with commas: two quotes should work now, e.g., 951938032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 952038032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 952138032Speter connections (domain-ized UUCP). 952238032Speter CONFIG: fix bug in default maps (-o must be before database file 952364562Sgshapiro name). Pointed out by Christophe Wolfhugel. 952438032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 952538032Speter DNS. This would presumably be used in UUCP islands. 952638032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 952738032Speter CONFIG: log $u in Received: line. This is in technical violation 952838032Speter of the standards, since it doesn't guarantee a domain 952938032Speter on the address. 953038032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 953138032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 953238032Speter the "m" flag should you want it. Apparently some Solaris 2.2 953338032Speter installations can't handle multiple local recipients. 953438032Speter Problem noted by Josh Smith. 953538032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 953638032Speter CONFIG: change default version level from 4 to 5. 953738032Speter CONFIG: add FEATURE(nullclient) to create a config file that 953838032Speter forwards all mail to a hub without ever looking at the 953938032Speter addresses in any detail. 954038032Speter CONFIG: properly strip mailer: information off of relays when 954138032Speter used to change .BITNET form into %-hack form. 954238032Speter CONFIG: fix a problem that caused infinite loops if presented 954338032Speter with an address such as "!foo". 954438032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 954538032Speter the reverse "PTR" mapping is broken. There's a better 954638032Speter way to do this, but the change is fairly major and I 954738032Speter want to hold it for another release. Problem noted by 954838032Speter Bret Marquis. 954938032Speter 955064562Sgshapiro8.5/8.5 1993/07/23 955138032Speter Serious bug: if you used a command line recipient that was unknown 955238032Speter sendmail would not send a return message (it was treating 955338032Speter everything as though it had an SMTP-style client that 955438032Speter would do the return itself). Problem noted by Josh Smith. 955538032Speter Change "trymx" option in getcanonname() to ignore all MX data, 955638032Speter even during a T_ANY query. This actually didn't break 955738032Speter anything, because the only time you called getcanonname 955838032Speter with !trymx was if you already knew there were no MX 955938032Speter records, but it is somewhat cleaner. From Motonori 956038032Speter Nakamura. 956138032Speter Don't call getcanonname from getmxrr if you already know there 956238032Speter are no DNS records matching the name. 956338032Speter Fix a problem causing error messages to always include "The 956438032Speter original message was received ... from localhost". 956538032Speter The correct original host information is now included. 956638032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 956738032Speter version of "test" doesn't have the -x flag). Change it 956838032Speter to use -f instead. From John Myers. 956938032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 957038032Speter esmtp -- it should be smtp. 957138032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 957238032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 957338032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 957438032Speter this cleans up the configs somewhat. This fixes a serious 957538032Speter problem that caused route-addrs to get mistaken as relays, 957638032Speter pointed out by John Myers. WARNING: this also causes 957738032Speter the default on SMART_HOST to change from "suucp" to 957838032Speter "relay" if you have MAILER(smtp) specified. 957938032Speter 958064562Sgshapiro8.4/8.4 1993/07/22 958138032Speter Add option `w'. If you receive a message that comes to you because 958238032Speter you are the best (lowest preference) target of an MX, and 958338032Speter you haven't explicitly recognized the source MX host in 958438032Speter your .cf file, this option will cause you to try the target 958538032Speter host directly (as if there were no MX for it at all). If 958638032Speter `w' is not set, this case is a configuration error. 958738032Speter Beware: if `w' is set, senders may get bogus errors like 958838032Speter "message timed out" or "host unknown" for problems that 958938032Speter are really configuration errors. This option is 959038032Speter disrecommended, provided only for compatibility with 959138032Speter UIUC sendmail. 959238032Speter Fix a problem that caused the incoming socket to be left open 959338032Speter when sendmail forks after the DATA command. This caused 959438032Speter calling systems to wait in FIN_WAIT_2 state until the 959538032Speter entire list was processed and the child closed -- a 959638032Speter potentially prodigious amount of time. Problem noted 959738032Speter by Neil Rickert. 959838032Speter Fix problem (created in 6.64) that caused mail sent to multiple 959938032Speter addresses, one of which was a bad address, to completely 960038032Speter suppress the sending of the message. This changes 960138032Speter handling of EF_FATALERRS somewhat, and adds an 960238032Speter EF_GLOBALERRS flag. This also fixes a potential problem 960338032Speter with duplicate error messages if there is a syntax error 960438032Speter in the header of a message that isn't noticed until late 960538032Speter in processing. Original problem pointed out by Josh Smith 960638032Speter of Harvey Mudd College. This release includes quite a bit 960738032Speter of dickering with error handling (see below). 960838032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 960938032Speter will only hurt already-broken software and should help 961038032Speter humans. 961138032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 961238032Speter compiled in. It would never read the alias file. 961338032Speter Repair unbalanced `)' and `>' (the "open" versions are already 961438032Speter repaired). 961538032Speter Logging of "done" in dropenvelope() was incorrect: it would 961638032Speter log this even when the queue file still existed. Change 961738032Speter this to only log "done" (at log level 11) when the 961838032Speter queue file is actually removed. From John Myers. 961938032Speter Log "lost connection" in server SMTP at log level 20 if there 962038032Speter is no pending transaction. Some senders just close the 962138032Speter connection rather than sending QUIT. 962238032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 962338032Speter domains that do not have MX records -- this would cause 962438032Speter the subsequent host name lookup to fail. The problem 962538032Speter only occurred if you had FEATURE(nocanonify) set. 962638032Speter Problem noted by Rick McCarty of Texas Instruments. 962738032Speter Fix invocation of setvbuf when passed a -X flag -- I had 962838032Speter unwittingly used an ANSI C extension, and this caused 962938032Speter core dumps on some machines. 963038032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 963138032Speter Previously it just gave an empty send queue, which 963238032Speter then gave either "Need RCPT (recipient)" at the DATA 963338032Speter (confusing, since you had given an RCPT command which 963438032Speter returned 250) or just dropped the email, depending on 963538032Speter whether you were running VERBose mode. Now it usually 963638032Speter diagnoses this case as "aliasing/forwarding loop broken". 963738032Speter Unfortunately, it still doesn't adequately diagnose 963838032Speter some true error conditions. 963938032Speter Add internal concept of "warning messages" using 6xx codes. 964038032Speter These are not reported only to Postmaster. Unbalanced 964138032Speter parens, brackets, and quotes are printed as 653 codes. 964238032Speter They are always mapped to 5xx codes before use in SMTP. 964338032Speter Clean up error messages to tell both the actual address that 964438032Speter failed and the alias they arose from. This makes it 964538032Speter somewhat easier to diagnose problems. Difficulty noted 964638032Speter by Motonori Nakamura. 964738032Speter Fix a problem that inappropriately added a ctladdr to addresses 964838032Speter that shouldn't have had one during a queue run. This 964938032Speter caused error messages to be handled differently during 965038032Speter a queue run than a direct run. 965138032Speter Don't print the qf name and line number if you get errors during 965238032Speter the direct run of the queue from srvrsmtp -- this was 965338032Speter just extra stuff for users to crawl through. 965438032Speter Put command line flags on second line of pid file so you can 965538032Speter auto-restart the daemon with all appropriate arguments. 965638032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 965738032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 965838032Speter restart it. 965938032Speter Remove the ``setuid(getuid())'' in main -- this caused the 966038032Speter IDENT daemon to screw up. This required that I change 966138032Speter HASSETEUID to HASSETREUID and complicate the mode 966238032Speter changing somewhat because both Ultrix and SunOS seem 966338032Speter to have a bug causing seteuid() to set the saved uid 966438032Speter as well as the effective. The program test/t_setreuid.c 966538032Speter will test to see if your implementation of setreuid(2) 966638032Speter is appropriately functional. 966738032Speter The FallBackMX (option V) handling failed to properly identify 966838032Speter fallback to yourself -- most of the code was there, 966938032Speter but it wasn't being enabled. Problem noted by Murray 967038032Speter Kucherawy of the University of Waterloo. 967138032Speter Change :include: open timeout from ETIMEDOUT to an internal 967238032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 967338032Speter with CurHostName" in error messages, which can be 967438032Speter confusing. Reported by Jonathan Kamens of OpenVision 967538032Speter Technologies. 967638032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 967738032Speter process group id. The original fix was to get around 967838032Speter some problems with recalcitrant MUAs, but it breaks 967938032Speter any call from a shell that creates a process group id 968038032Speter different from the process id. I could try to fix 968138032Speter this by diddling the tty owner (using tcsetpgrp or 968238032Speter equivalent) but this is too likely to break other 968338032Speter things. 968438032Speter Portability changes: 968538032Speter Support -M as equivalent to -oM on Ultrix -- apparently 968638032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 968738032Speter instead of using standard flags. Oh joy. This 968843730Speter behavior reported by Jon Giltner of University 968938032Speter of Colorado. 969038032Speter SGI IRIX -- this includes several changes that should 969138032Speter help other strict ANSI compilers. 969238032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 969338032Speter Corporation. 969438032Speter Solaris running the Sun C compiler (which despite the 969538032Speter documentation apparently doesn't define 969638032Speter __STDC__ by default). 969738032Speter ConvexOS from Eric Schnoebelen of Convex. 969838032Speter Sony NEWS workstations and Omron LUNA workstations from 969938032Speter Motonori Nakamura. 970038032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 970138032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 970238032Speter several people have made a good argument that this 970338032Speter creates more problems than it solves (although this 970438032Speter may prove painful in the short run). 970538032Speter CONFIG: generalize all the relays to accept a "mailer:host" 970638032Speter format. 970738032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 970838032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 970938032Speter addresses are also passed through this ruleset. 971038032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 971138032Speter internet-style addresses would "fall off the end" of 971238032Speter ruleset zero and be interpreted as local -- however, 971338032Speter the angle brackets confused the recursive call. 971438032Speter These are now diagnosed as "Unrecognized host name". 971538032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 971638032Speter ifdef(`_MAILER_USENET_') instead of 971738032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 971838032Speter of SINTEF RUNIT, Oslo. 971938032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 972038032Speter early in ruleset 0; this allows .mc authors to bypass 972138032Speter things like the "short circuit" code for local addresses. 972238032Speter Prompted by a comment by Bill Wisner of The Well. 972338032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 972438032Speter esmtp) to send SMTP mail. This allows you to default 972538032Speter to esmtp but use a mailertable or other override to 972638032Speter deal with broken servers. This logic was pointed out 972738032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 972838032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 972938032Speter environments. Ugly as sin. 973038032Speter 973164562Sgshapiro8.3/8.3 1993/07/13 973238032Speter Fix setuid problems introduced in 8.2 that caused messages 973338032Speter like "Cannot create qfXXXXXX: Invalid argument" 973438032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 973538032Speter involved a new compile flag "HASSETEUID" that takes 973638032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 973738032Speter that the POSIX interface is broken enough to break 973838032Speter some systems badly. This includes some fixes for 973938032Speter HP-UX. Also fixes problems where the real uid is 974038032Speter not reset properly on startup (from Neil Rickert). 974138032Speter Fix a problem that caused timed out messages to not report the 974238032Speter addresses that timed out. Error messages are also more 974338032Speter "user friendly". 974438032Speter Drop required bandwidth on connections from 64 bytes/sec to 974538032Speter 16 bytes/sec. 974638032Speter Further Solaris portability changes -- doesn't require the BSD 974738032Speter compatibility library. This also adds a new 974838032Speter "HASGETDTABLESIZE" compile flag which can be used if 974938032Speter you want to use getdtablesize(2) instead of sysconf(2). 975038032Speter These are loosely based on changes from David Meyer at 975138032Speter University of Oregon. This now seems to work, at least 975238032Speter for quick test cases. 975338032Speter Fix a problem that can cause duplicate error messages to be 975438032Speter sent if you are in SMTP, you send to multiple addresses, 975538032Speter and at least one of those addresses is good and points 975638032Speter to an account that has a .forward file (whew!). 975738032Speter Fix a problem causing messages to be discarded if checkcompat() 975838032Speter returned EX_TEMPFAIL (because it didn't properly mark 975938032Speter the "to" address). Problem noted by John Myers. 976038032Speter Fix dfopen to return NULL if the open failed; I was depending 976138032Speter on fdopen(-1) returning NULL, which isn't the case. This 976238032Speter isn't serious, but does result in weird error diagnoses. 976338032Speter From Michael Corrigan. 976438032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 976538032Speter messages sent through UUCP-family mailers. Suggested 976638032Speter by Bill Wisner of The Well. 976738032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 976838032Speter include a "uucp-dom" mailer that uses domain-style 976938032Speter addressing. Suggested by Bill Wisner. 977038032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 977138032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 977238032Speter Christophe Wolfhugel. 977338032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 977438032Speter 977564562Sgshapiro8.2/8.2 1993/07/11 977638032Speter Don't drop out on config file parse errors in -bt mode. 977738032Speter On older configuration files, assume option "l" (use Errors-To 977838032Speter header) for back compatibility. NOTE: this DOES NOT 977938032Speter imply an endorsement of the Errors-To: header in any way. 978038032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 978138032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 978238032Speter SMTP server to give an error on this command, and 978338032Speter logging it in the transcript can be confusing. Fix 978438032Speter from Bill Wisner. 978538032Speter IRIX compatibility changes provided by Dan Rich 978638032Speter <drich@sandman.lerc.nasa.gov>. 978738032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 978838032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 978938032Speter <juo@klinzhai.rutgers.edu> 979038032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 979138032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 979238032Speter match the other flags in that file. 979338032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 979438032Speter Save h_errno in mci struct and improve error message display. 979538032Speter Changes from Eric Wassenaar. 979638032Speter Open /dev/null for the transcript if the create of the xf file 979738032Speter failed; this avoids at least one possible null pointer 979838032Speter reference in very weird cases. From Eric Wassenaar. 979938032Speter Clean up statistics gathering; it was over-reporting because of 980038032Speter forks. From Eric Wassenaar. 980138032Speter Fix problem that causes old Return-Path: line to override new 980238032Speter Return-Path: line (conf.c needs H_FORCE to avoid 980338032Speter re-using old value). From Motonori Nakamura. 980438032Speter Fix broken -m flag in K definition -- even if -m (match only) 980538032Speter was specified, it would still replace the key with the 980638032Speter value. Noted by Rick McCarty of Texas Instruments. 980738032Speter If the name server timed out over several days, no "timed out" 980838032Speter message would ever be sent back. The timeout code 980938032Speter has been moved from markfailure() to dropenvelope() 981038032Speter so that all such failures should be diagnosed. Pointed 981138032Speter out by Christophe Wolfhugel and others. 981238032Speter Relax safefile() constraints: directories in an include or 981338032Speter forward path must be readable by self if the controlling 981438032Speter user owns the entry, readable by all otherwise (e.g., 981538032Speter when reading your .forward file, you have to own and 981638032Speter have X permission in it; everyone needs X permission in 981738032Speter the root and directories leading up to your home); 981838032Speter include files must be readable by anyone, but need not 981938032Speter be owned by you. 982038032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 982138032Speter reading a .forward file; this gets around some problems 982238032Speter on NFS mounts if root permission is not exported and 982338032Speter the user's home directory isn't x'able. 982438032Speter Additional NeXT portability enhancements from Axel Zinser. 982538032Speter Additional HP-UX portability enhancements from Brian Bullen. 982638032Speter Add a timeout around SMTP message writes; this assumes you can 982738032Speter get throughput of at least 64 bytes/second. Note that 982838032Speter this does not impact the "datafinal" default, which 982938032Speter is separate; this is just intended to work around 983038032Speter network clogs that will occur before the final dot 983138032Speter is sent. From Eric Wassenaar. 983238032Speter Change map code to set the "include null" flag adaptively -- 983338032Speter it initially tries both, but if it finds anything 983438032Speter matching without a null it never tries again with a 983538032Speter null and vice versa. If -N is specified, it never 983638032Speter tries without the null and creates new maps with a 983738032Speter null byte. If -O is specified, it never tries with 983838032Speter the null (for efficiency). If -N and -O are specified, 983938032Speter you get -NO (get it?) lookup at all, so this would 984038032Speter be a bad idea. If you don't specify either -N or -O, 984138032Speter it adapts. 984238032Speter Fix recognition of "same from address" so that MH submissions 984338032Speter will insert the appropriate full name information; 984438032Speter this used to work and got broken somewhere along the 984538032Speter way. 984638032Speter Some changes to eliminate some unnecessary SYSERRs in the 984738032Speter log. For example, if you lost a connection, don't 984838032Speter bother reporting that fact on the connection you lost. 984938032Speter Add some "extended debugging" flags to try to track down 985038032Speter why we get occasional problems with file descriptor 985138032Speter one being closed when execing a mailer; it seems to 985238032Speter only happen when there has been another error in the 985338032Speter same transaction. This requires XDEBUG, defined 985438032Speter by default in conf.h. 985538032Speter Add "-X filename" command line flag, which logs both sides of 985638032Speter all SMTP transactions. This is intended ONLY for 985738032Speter debugging bad implementations of other mailers; start 985838032Speter it up, send a message from a mailer that is failing, 985938032Speter and then kill it off and examine the indicated log. 986038032Speter This output is not intended to be particularly human 986138032Speter readable. This also adds the HASSETVBUF compile 986238032Speter flag, defaulted on if your compiler defines __STDC__. 986338032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 986438032Speter have a local net that should get direct connects, you 986538032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 986638032Speter See cf/README for an example. 986738032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 986838032Speter sites that don't use the -d flag. 986938032Speter CONFIG: hide recipient addresses as well as sender addresses 987038032Speter behind $M if FEATURE(allmasquerade) is specified; this 987138032Speter has been requested by several people, but can break 987238032Speter local aliases. For example, if you mail to "localalias" 987338032Speter this will be rewritten as "localalias@masqueradehost"; 987438032Speter although initial delivery will work, replies will be 987538032Speter broken. Use it sparingly. 987638032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 987738032Speter to qualified domains in headers. I believe this is 987838032Speter largely equivalent to the IDA feature of the same name. 987938032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 988038032Speter to override the "system name" as your UUCP name -- 988138032Speter in particular, to use domain-ized UUCP names. From 988238032Speter Bill Wisner of The Well. 988338032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 988438032Speter first. This is currently unused in the config files, 988538032Speter but could be used in a mailertable entry. 988638032Speter 988764562Sgshapiro8.1C/8.1B 1993/06/27 988838032Speter Serious security bug fix: it was possible to read any file on 988938032Speter the system, regardless of ownership and permissions. 989038032Speter If a subroutine returns a fully qualified address, return it 989138032Speter immediately instead of feeding it back into rewriting. 989238032Speter This fixes a problem with mailertable lookups. 989338032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 989438032Speter 989564562Sgshapiro8.1B/8.1A 1993/06/12 989638032Speter Serious bug fix: pattern matching backup algorithm stepped by 989738032Speter two tokens in classes instead of one.
