Patch inspired 13203004Sgshapiro by Matthias Andree's changes for fetchmail. 14203004Sgshapiro During the generation of a queue identifier an integer overflow 15203004Sgshapiro could occur which might result in bogus characters 16203004Sgshapiro being used. Based on patch from John Vannoy of 17203004Sgshapiro Pepperdine University. 18203004Sgshapiro The value of headers, e.g., Precedence, Content-Type, et.al., 19203004Sgshapiro was not processed correctly. Patch from Per Hedeland. 20203004Sgshapiro Between 8.11.7 and 8.12.0 the length limitation on a return 21203004Sgshapiro path was erroneously reduced from MAXNAME (256) to 22203004Sgshapiro MAXSHORTSTR (203). Patch from John Gardiner Myers 23203004Sgshapiro of Proofpoint; the problem was also noted by Steve 24203004Sgshapiro Hubert of University of Washington. 25203004Sgshapiro Prevent a crash when a hostname lookup returns a seemingly 26203004Sgshapiro valid result which contains a NULL pointer (this seems 27203004Sgshapiro to be happening on some Linux versions). 28203004Sgshapiro The process title was missing the current load average when 29203004Sgshapiro the MTA was delaying connections due to DelayLA. 30203004Sgshapiro Patch from Dick St.Peters of NetHeaven. 31203004Sgshapiro Do not reset the number of queue entries in shared memory if 32203004Sgshapiro only some of them are processed. 33203004Sgshapiro Fix overflow of an internal array when parsing some replies 34203004Sgshapiro from a milter. Problem found by Scott Rotondo 35203004Sgshapiro of Sun Microsystems. 36203004Sgshapiro If STARTTLS is turned off in the server (via M=S) then it 37203004Sgshapiro would not be initialized for use in the client either. 38203004Sgshapiro Patch from Kazuteru Okahashi of IIJ. 39203004Sgshapiro If a Diffie-Hellman cipher is selected for STARTTLS, the 40203004Sgshapiro handshake could fail with some TLS implementations 41203004Sgshapiro because the prime used by the server is not long enough. 42203004Sgshapiro Note: the initialization of the DSA/DH parameters for 43203004Sgshapiro the server can take a significant amount of time on slow 44203004Sgshapiro machines. This can be turned off by setting DHParameters 45203004Sgshapiro to none or a file (see doc/op/op.me). Patch from 46203004Sgshapiro Petr Lampa of the Brno University of Technology. 47203004Sgshapiro Fix handling of `b' modifier for DaemonPortOptions on little 48203004Sgshapiro endian machines for loopback address. Patch from 49203004Sgshapiro John Beck of Sun Microsystems. 50203004Sgshapiro Fix a potential memory leak in libsmdb/smdb1.c found by parfait. 51203004Sgshapiro Based on patch from Jonathan Gray of OpenBSD. 52203004Sgshapiro If a milter sets the reply code to "421" during the transfer 53203004Sgshapiro of the body, the SMTP server will terminate the SMTP session 54203004Sgshapiro with that error to match the behavior of the other callbacks. 55203004Sgshapiro Return EX_IOERR (instead of 0) if a mail submission fails due to 56203004Sgshapiro missing disk space in the mail queue. Based on patch 57203004Sgshapiro from Martin Poole of RedHat. 58203004Sgshapiro CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would 59203004Sgshapiro cause addresses not found in LDAP to be misparsed. 60203004Sgshapiro CONFIG: Using a CN restriction did not work for TLS_Clt as it 61203004Sgshapiro referred to a wrong macro. Patch from John Gardiner 62203004Sgshapiro Myers of Proofpoint. 63203004Sgshapiro CONFIG: The option relaytofulladdress of FEATURE(`access_db') 64203004Sgshapiro did not work if FEATURE(`relay_hosts_only') is used too. 65203004Sgshapiro Problem noted by Kristian Shaw. 66203004Sgshapiro CONFIG: The internal function lower() was broken and hence 67203004Sgshapiro strcasecmp() did not work either, which could cause 68203004Sgshapiro problems for some FEATURE()s if upper case arguments 69203004Sgshapiro were used. Patch from Vesa-Matti J Kari of the 70203004Sgshapiro University of Helsinki. 71203004Sgshapiro LIBMILTER: Fix internal check whether a milter application 72203004Sgshapiro is compiled against the same version of libmilter as 73203004Sgshapiro it is linked against (especially useful for dynamic 74203004Sgshapiro libraries). 75203004Sgshapiro LIBMILTER: Fix memory leak that occurred when smfi_setsymlist() 76203004Sgshapiro was used. Based on patch by Dan Lukes. 77203004Sgshapiro LIBMILTER: Document the effect of SMFIP_HDR_LEADSPC for filters 78203004Sgshapiro which add, insert, or replace headers. From Benjamin 79203004Sgshapiro Pineau. 80203004Sgshapiro LIBMILTER: Fix error messages which refer to "select()" to be 81203004Sgshapiro correct if SM_CONF_POLL is used. Based on patch from 82203004Sgshapiro John Nemeth. 83203004Sgshapiro LIBSM: Fix handling of LDAP search failures where the error is 84203004Sgshapiro carried in the search result itself, such as seen with 85203004Sgshapiro OpenLDAP proxy servers. 86203004Sgshapiro VACATION: Do not refer to a local variable outside its scope. 87203004Sgshapiro Based on patch from Mark Costlow of Southwest Cyberport. 88203004Sgshapiro Portability: 89203004Sgshapiro Enable HAVE_NANOSLEEP for SunOS 5.11. Patch from 90203004Sgshapiro John Beck of Sun Microsystems. 91203004Sgshapiro Drop NISPLUS from default SunOS 5.11 map definitions. 92203004Sgshapiro Patch from John Beck of Sun Microsystems. 93203004Sgshapiro 94182352Sgshapiro8.14.3/8.14.3 2008/05/03 95182352Sgshapiro During ruleset processing the generation of a key for a map 96182352Sgshapiro lookup and the parsing of the default value was broken 97182352Sgshapiro for some macros, e.g., $|, which caused the BlankSub 98182352Sgshapiro character to be inserted into the workspace and thus 99182352Sgshapiro failures, e.g., rules that should have matched did not. 100182352Sgshapiro 8.14.2 caused a regression: it accessed (macro) storage which was 101182352Sgshapiro freed before. First instance of the problem reported by 102182352Sgshapiro Matthew Dillon of DragonFlyBSD; variations of the same 103182352Sgshapiro bug reported by Todd C. Miller of OpenBSD, Moritz 104182352Sgshapiro Jodeit, and Dave Hayes. 105182352Sgshapiro Improve pathname length checks for persistent host status. Patch 106182352Sgshapiro from Joerg Sonnenberger of DragonFlyBSD. 107182352Sgshapiro Reword misleading SMTP reply text for FEATURE(`badmx'). Problem 108182352Sgshapiro noted by Beth Halsema. 109182352Sgshapiro The read timeout was fixed to be Timeout.datablock if STARTTLS 110182352Sgshapiro was activated. This may cause problems if that value 111182352Sgshapiro is lowered from its default. Problem noted by Jens Elkner. 112182352Sgshapiro CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset 113182352Sgshapiro to operate incorrectly. Problem found by Werner Wiethege. 114182352Sgshapiro LIBMILTER: Omitting some protocol steps via the xxfi_negotiate() 115182352Sgshapiro callback did not work properly. The patchlevel of 116182352Sgshapiro libmilter has been set to 1 so a milter can determine 117182352Sgshapiro whether libmilter contains this fix. 118182352Sgshapiro MAKEMAP: If a delimiter is specified (-t) use that also when 119182352Sgshapiro dumping a map. Patch from Todd C. Miller of OpenBSD. 120182352Sgshapiro Portability: 121182352Sgshapiro Add support for Darwin 9.x (Mac OS X 10.5). 122182352Sgshapiro Support shared libraries in Darwin 8 and 9. Patch from 123182352Sgshapiro Chris Behrens of Concentric. 124182352Sgshapiro Add support for SCO OpenServer 6, patch from Boyd Gerber. 125203004Sgshapiro DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing slash. 126182352Sgshapiro Added Files: 127182352Sgshapiro devtools/OS/Darwin.9.x 128182352Sgshapiro devtools/OS/OSR.i386 129182352Sgshapiro 130173340Sgshapiro8.14.2/8.14.2 2007/11/01 131173340Sgshapiro If a message was queued and it contained 8 bit characters in 132173340Sgshapiro a From: or To: header, then those characters could be 133173340Sgshapiro "mistaken" for internal control characters during a queue 134173340Sgshapiro run and trigger various consistency checks. Problem 135173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 136173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 137173340Sgshapiro it is by default) then even if the Linelimit parameter 138173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 139173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 140173340Sgshapiro Myers of Proofpoint. 141173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 142173340Sgshapiro work in earlier 8.14 versions. 143173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 144173340Sgshapiro background if a milter can reject or delete a recipient. 145173340Sgshapiro Prior to 8.14 this happened only if milter could delete 146173340Sgshapiro recipients. 147173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 148182352Sgshapiro documented), not when it was reached. Patch from 149173340Sgshapiro John Beck of Sun Microsystems. 150173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 151173340Sgshapiro specified (R=0) and forking (F=f) is requested. 152173340Sgshapiro When multiple results are requested for a DNS map lookup 153173340Sgshapiro (-z and -Z), return only those that are relevant for 154173340Sgshapiro the query (not also those in the "additional section".) 155173340Sgshapiro If the message transfer time to sendmail (when acting as server) 156173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 157173340Sgshapiro the message is refused (by a milter), sendmail previously 158173340Sgshapiro created a delivery status notification (DSN). Patch 159173340Sgshapiro from Doug Heath of The Hertz Corporation. 160173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 161173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 162173340Sgshapiro Problem noted by Eliot Lear. 163173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 164173340Sgshapiro compiled in but not offered by the server and the 165173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 166173340Sgshapiro If getting the result of an LDAP query times out then close the 167173340Sgshapiro map so it will be reopened on the next lookup. This 168173340Sgshapiro should help "failover" configurations that specify more 169173340Sgshapiro than one LDAP server. 170173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 171173340Sgshapiro be triggered under some circumstances (e.g., requiring 172173340Sgshapiro a system which does not have the compile time flag 173173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 174173340Sgshapiro of National Institute of Informatics, Japan. 175173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 176173340Sgshapiro logfile entry might have been wrong. Problem found by 177173340Sgshapiro Petra Humann of TU Dresden. 178173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 179173340Sgshapiro NULL, the message body was lost. Patch from Motonori 180173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 181173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 182173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 183173340Sgshapiro replacing files. 184173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 185173340Sgshapiro reading the /etc/mail/virtusers/ directory. 186173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 187173340Sgshapiro appropriate. 188173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 189173340Sgshapiro against an older libmilter.so shared library can use an 190173340Sgshapiro 8.14 libmilter.so shared library. 191173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 192173340Sgshapiro from the version number, however, the returned value was 193173340Sgshapiro correct for the current libmilter version. 194173340Sgshapiro 195168515Sgshapiro8.14.1/8.14.1 2007/04/03 196168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 197168515Sgshapiro it in its list of recipients and deliver to it if the 198168515Sgshapiro transaction is accepted. This is a regression introduced 199168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 200168515Sgshapiro found by Andy Fiddaman. 201168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 202168515Sgshapiro could not be set in 8.14.0. 203168515Sgshapiro If a server shut down the connection in response to a STARTTLS 204168515Sgshapiro command, sendmail would log a misleading error message 205168515Sgshapiro due to an internal inconsistency. Problem found by 206168515Sgshapiro Werner Wiethege. 207168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 208168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 209168515Sgshapiro Science and Mathematics. 210168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 211168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 212168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 213168515Sgshapiro m4 options for setting MaxNOOPCommands and 214168515Sgshapiro SharedMemoryKeyFile. 215168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 216168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 217168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 218168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 219168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 220168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 221168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 222168515Sgshapiro negotiation. Problem reported by Bryan Costales. 223168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 224168515Sgshapiro Patches from Bryan Costales. 225168515Sgshapiro PORTABILITY FIXES: 226168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 227168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 228168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 229168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 230168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 231168515Sgshapiro Software Systems. 232168515Sgshapiro New Files: 233168515Sgshapiro devtools/M4/depend/QNX6.m4 234168515Sgshapiro devtools/OS/QNX.6.x 235168515Sgshapiro include/sm/os/sm_os_qnx.h 236168515Sgshapiro 237168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 238168515Sgshapiro libmilter/docs/smfi_chgfrom.html 239168515Sgshapiro libmilter/docs/smfi_version.html 240168515Sgshapiro 241168515Sgshapiro8.14.0/8.14.0 2007/01/31 242168515Sgshapiro Header field values are now 8 bit clean. Notes: 243168515Sgshapiro - header field names are still restricted to 7 bit. 244168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 245168515Sgshapiro headers. 246168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 247168515Sgshapiro number of spaces after the colon would be changed to 248168515Sgshapiro exactly one space. 249168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 250168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 251168515Sgshapiro limit may be reached too early, e.g., the counter 252168515Sgshapiro may be off by a factor of 4 in case of a sequence of 253168515Sgshapiro .forward files that refer to others. Patch from 254168515Sgshapiro Motonori Nakamura of Kyoto University. 255168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 256168515Sgshapiro "sendmail -bs" can trigger an assertion because the 257168515Sgshapiro hostname of the client is undefined. It is now set 258168515Sgshapiro to "localhost" for the xxfi_connect() callback. 259168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 260168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 261168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 262168515Sgshapiro Patch from Nik Clayton. 263168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 264168515Sgshapiro permanent errors (5xy). This can be useful for testing. 265168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 266168515Sgshapiro per daemon socket: 267168515Sgshapiro DeliveryMode DeliveryMode 268168515Sgshapiro refuseLA RefuseLA 269168515Sgshapiro delayLA DelayLA 270168515Sgshapiro queueLA QueueLA 271168515Sgshapiro children MaxDaemonChildren 272168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 273168515Sgshapiro lookup key with the LDAP escaped contents of the 274168515Sgshapiro arguments specified in the map lookup. Loosely based 275168515Sgshapiro on patch from Wolfgang Hottgenroth. 276168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 277168515Sgshapiro from Nik Clayton. 278168515Sgshapiro If a client is rejected via TCP wrapper or some other check 279168515Sgshapiro performed by validate_connection() (in conf.c) then do 280168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 281168515Sgshapiro of the University of Illinois at Urbana-Champaign. 282168515Sgshapiro If a client terminates the SMTP connection during a pause 283168515Sgshapiro introduced by greet_pause, then a misleading message 284168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 285168515Sgshapiro et.al., patch from Matej Vela. 286168515Sgshapiro New command "mstat" for control socket to provide "machine 287168515Sgshapiro readable" status. 288168515Sgshapiro New named config file rule check_eom which is called at the end 289168515Sgshapiro of a message, its parameter is the size of the message. 290168515Sgshapiro If the macro {addr_type} indicates that the current address 291168515Sgshapiro is a header address it also distinguishes between 292168515Sgshapiro recipient and sender addresses (as it is done for 293168515Sgshapiro envelope addresses). 294168515Sgshapiro When a macro is set in check_relay, then its value is accessible 295168515Sgshapiro by all transactions in the same SMTP session. 296168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 297168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 298168515Sgshapiro number of "useless" commands before the SMTP server will 299168515Sgshapiro slow down responding. 300168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 301168515Sgshapiro enabled, the MTA can be asked to select a shared memory 302168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 303168515Sgshapiro a file where to store the selected key. 304168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 305168515Sgshapiro by recognizing some commands from them. If the first command 306168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 307168515Sgshapiro connection is terminated immediately. 308168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 309168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 310168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 311168515Sgshapiro New options B, z, and Z for DNS maps: 312168515Sgshapiro -B: specify a domain that is always appended to queries. 313168515Sgshapiro -z: specify the delimiter at which to cut off the result of 314168515Sgshapiro a query if it is too long. 315168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 316168515Sgshapiro to form the result of a lookup. 317168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 318168515Sgshapiro implicitly while building libsm, they must be explicitly 319168515Sgshapiro started by using "make check". 320168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 321168515Sgshapiro reported by the SATURN tool which has been developed by 322168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 323168515Sgshapiro Fix a potential race condition caused by a signal handler for 324168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 325168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 326168515Sgshapiro queue group selection. This has been disabled as it was not 327168515Sgshapiro intended. 328168515Sgshapiro New operator 'r' for the arith map to return a random number. 329168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 330168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 331168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 332168515Sgshapiro which may improve the communication performance on some 333168515Sgshapiro operating systems. Patch from John Gardiner Myers of 334168515Sgshapiro Proofpoint. 335168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 336168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 337168515Sgshapiro generate an additional blank line in the output as the last 338168515Sgshapiro line. 339168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 340168515Sgshapiro the "queue control process" (QCP) works now. 341168515Sgshapiro Increase the length of an input line to 12288 to deal with 342168515Sgshapiro really long lines during SMTP AUTH negotiations. 343168515Sgshapiro Problem noted by Werner Wiethege. 344168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 345168515Sgshapiro a missing initialization call for that case). Problem 346168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 347168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 348168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 349168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 350168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 351168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 352168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 353168515Sgshapiro the MTA will not attempt to open a statistics file on 354168515Sgshapiro each delivery. 355168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 356168515Sgshapiro clients whose IP address does not have proper reverse DNS. 357168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 358168515Sgshapiro and John Beck of Sun Microsystems. 359168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 360168515Sgshapiro clients which provide a HELO/EHLO argument which is either 361168515Sgshapiro unqualified, or is one of our own names (i.e., the server 362168515Sgshapiro name instead of the client name). Contributed by Neil 363168515Sgshapiro Rickert of Northern Illinois University and John Beck of 364168515Sgshapiro Sun Microsystems. 365168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 366168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 367168515Sgshapiro Based on contribution from William Dell Wisner. 368168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 369168515Sgshapiro the maximum line length of the smtp mailers. 370168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 371168515Sgshapiro to allow entries in the access map to be of the form 372168515Sgshapiro To:user@example.com RELAY 373168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 374168515Sgshapiro macros a milter should receive at those stages in the 375168515Sgshapiro SMTP dialogue. 376168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 377168515Sgshapiro for the HELO/EHLO command. 378168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 379168515Sgshapiro messages by using those values as second argument. 380168515Sgshapiro Patches from Nelson Fung. 381168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 382168515Sgshapiro ignores everything after it unless it is in quotes or 383168515Sgshapiro preceeded by a backslash. 384168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 385168515Sgshapiro directories, then it used for "make install" to create 386168515Sgshapiro the required installation directories. 387168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 388168515Sgshapiro executables (defaults to confCC). 389168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 390168515Sgshapiro has several changes which are listed below and documented 391168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 392168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 393168515Sgshapiro changed. It now refers only to the version of libmilter, 394168515Sgshapiro not to the protocol version (which is used only internally, 395168515Sgshapiro it is not user/milter-programmer visible). Additionally, 396168515Sgshapiro a version function smfi_version() has been introduced such 397168515Sgshapiro that a milter program can check the libmilter version also 398168515Sgshapiro at runtime which is useful if a shared library is used. 399168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 400168515Sgshapiro dynamically (i.e., at runtime) determine the available 401168515Sgshapiro protocol actions and features of the MTA and also to 402168515Sgshapiro specify which of these a milter wants to use. This allows 403168515Sgshapiro for more flexibility than hardcoding these flags in the 404168515Sgshapiro xxfi_flags field of the smfiDesc structure. 405168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 406168515Sgshapiro can act on the DATA command. 407168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 408168515Sgshapiro can receive also unknown SMTP commands. 409168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 410168515Sgshapiro can be used by the xxfi_header() callback provided the 411168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 412168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 413168515Sgshapiro xxfi_body() callback to skip over further body chunks 414168515Sgshapiro and directly advance to the xxfi_eom() callback. This 415168515Sgshapiro is useful if a milter can make a decision based on the 416168515Sgshapiro body chunks it already received without reading the entire 417168515Sgshapiro rest of the body and the milter wants to invoke functions 418168515Sgshapiro that are only available from the xxfi_eom() callback. 419168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 420168515Sgshapiro new recipients including ESMTP parameters. 421168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 422168515Sgshapiro envelope sender including ESMTP parameters. 423168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 424168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 425168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 426168515Sgshapiro a RCPT has been rejected can be checked by comparing the 427168515Sgshapiro value of the macro {rcpt_mailer} with "error". 428168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 429168515Sgshapiro wants to receive from the MTA for each protocol step 430168515Sgshapiro by invoking the function smfi_setsymlist() during option 431168515Sgshapiro negotiation. 432168515Sgshapiro LIBMILTER: A milter can receive header field values with all 433168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 434168515Sgshapiro protocol action. Also, if the flag is set then the MTA 435168515Sgshapiro does not add a leading space to headers that are added, 436168515Sgshapiro inserted, or replaced. 437168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 438168515Sgshapiro callback, the SMTP server will terminate the SMTP session 439168515Sgshapiro with that error to match the behavior of all other callbacks. 440168515Sgshapiro New Files: 441168515Sgshapiro cf/feature/badmx.m4 442168515Sgshapiro cf/feature/block_bad_helo.m4 443168515Sgshapiro cf/feature/require_rdns.m4 444168515Sgshapiro devtools/M4/UNIX/check.m4 445168515Sgshapiro include/sm/misc.h 446168515Sgshapiro include/sm/sendmail.h 447168515Sgshapiro include/sm/tailq.h 448168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 449168515Sgshapiro libmilter/docs/smfi_setsymlist.html 450168515Sgshapiro libmilter/docs/xxfi_data.html 451168515Sgshapiro libmilter/docs/xxfi_negotiate.html 452168515Sgshapiro libmilter/docs/xxfi_unknown.html 453168515Sgshapiro libmilter/example.c 454168515Sgshapiro libmilter/monitor.c 455168515Sgshapiro libmilter/worker.c 456168515Sgshapiro libsm/memstat.c 457168515Sgshapiro libsm/t-memstat.c 458168515Sgshapiro libsm/t-qic.c 459168515Sgshapiro libsm/util.c 460168515Sgshapiro sendmail/daemon.h 461168515Sgshapiro sendmail/map.h 462168515Sgshapiro 463161389Sgshapiro8.13.8/8.13.8 2006/08/09 464161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 465161389Sgshapiro the server can erroneously report that there is 466161389Sgshapiro insufficient disk space. Additionally make sure that 467161389Sgshapiro an internal variable is set properly to avoid those 468161389Sgshapiro misleading errors. Based on patch from Steve Hubert 469161389Sgshapiro of University of Washington. 470161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 471161389Sgshapiro the process that forks the daemon exited, i.e., if 472161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 473161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 474161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 475161389Sgshapiro David F. Skoll. 476161389Sgshapiro Avoid a crash when finishing due to referencing a freed variable. 477161389Sgshapiro Problem reported and diagnosed by Moritz Jodeit. 478161389Sgshapiro CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4 479161389Sgshapiro range (0..255). 480161389Sgshapiro LIBMILTER: The "hostname" argument of the xxfi_connect() callback 481161389Sgshapiro previously was the equivalent of {client_ptr}. However, 482161389Sgshapiro this did not match the documentation of the function, hence 483161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 484161389Sgshapiro about these macros. 485161389Sgshapiro 486159609Sgshapiro8.13.7/8.13.7 2006/06/14 487159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 488159609Sgshapiro crash while trying to send a mail due to a stack overflow, 489159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 490159609Sgshapiro happens because the recursion of the function mime8to7() 491159609Sgshapiro was not restricted. The function is called for MIME 8 to 492159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 493159609Sgshapiro To work around this problem, recursive calls are limited to 494159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 495159609Sgshapiro limit is treated as opaque and is not checked further. 496159609Sgshapiro Problem noted by Frank Sheiness. 497159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 498159609Sgshapiro SASL mechanisms that use the security layer, e.g., 499159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 500159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 501159609Sgshapiro a df file might have been left behind in the queue. 502159609Sgshapiro This was another side effect of the changes to the I/O 503159609Sgshapiro layer made in 8.13.6. 504159609Sgshapiro Several minor problems have been fixed that were found by a 505159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 506159609Sgshapiro distribution. See http://scan.coverity.com/ 507159609Sgshapiro Note: the scan generated also a lot of "false positives", 508159609Sgshapiro e.g., "error" reports about situations that cannot happen. 509159609Sgshapiro Most of those code places are marked with lint(1) comments 510159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 511159609Sgshapiro Hence an explicit assertion has been added in some cases 512159609Sgshapiro to avoid those false positives. 513159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 514159609Sgshapiro error then in some cases shared memory segments or pid 515159609Sgshapiro files were not removed. 516159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 517159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 518159609Sgshapiro reported by Akihiro Sagawa. 519159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 520159609Sgshapiro bug work-around. Hence if sendmail is linked against 521159609Sgshapiro either of these versions and compression is available, 522159609Sgshapiro the padding bug work-around is turned off. Based on 523159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 524159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 525159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 526159609Sgshapiro however, that list is no longer available. To avoid 527159609Sgshapiro further problems, no default value is available anymore, 528159609Sgshapiro but an argument must be specified. 529159609Sgshapiro Portability: 530159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c. Patch from 531159609Sgshapiro Pieter Bowman of the University of Utah. 532159609Sgshapiro 533157001Sgshapiro8.13.6/8.13.6 2006/03/22 534157001Sgshapiro SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server 535157001Sgshapiro and client side of sendmail with timeouts in the libsm I/O 536157001Sgshapiro layer and fix problems in that code. Also fix handling of 537157001Sgshapiro a buffer in sm_syslog() which could have been used as an 538157001Sgshapiro attack vector to exploit the unsafe handling of 539157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 540157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 541157001Sgshapiro Handle theoretical integer overflows that could triggered if 542157001Sgshapiro the server accepted headers larger than the maximum 543157001Sgshapiro (signed) integer value. This is prevented in the default 544157001Sgshapiro configuration by restricting the size of a header, and on 545157001Sgshapiro most machines memory allocations would fail before reaching 546157001Sgshapiro those values. Problems found by Phil Brass of ISS. 547157001Sgshapiro If a server returns 421 for an RSET command when trying to start 548157001Sgshapiro another transaction in a session while sending mail, do 549157001Sgshapiro not trigger an internal consistency check. Problem found 550157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 551157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 552157001Sgshapiro to a STARTTLS command despite the fact that it advertised 553157001Sgshapiro STARTTLS and that the code is not valid according to RFC 554157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 555157001Sgshapiro of a protocol error (which has been changed to a 556157001Sgshapiro temporary error in 8.13.5).

This prevents bogus "Bad 721141858Sgshapiro file number" recipient status. Problem noted by 722141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 723141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 724141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 725141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 726141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 727141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 728141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 729141858Sgshapiro them off at a comma.

This allows 815132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 816132943Sgshapiro URL which will in turn be queried. See the ``LDAP 817132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 818132943Sgshapiro Based on patch from Andrew Baucom. 819132943Sgshapiro Extend the default LDAP specifications for AliasFile 820132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 821132943Sgshapiro include support for LDAP recursion via new attributes. 822132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 823132943Sgshapiro of cf/README for more information. 824132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 825132943Sgshapiro LDAP API/protocol version to use. The default depends on 826132943Sgshapiro the LDAP library. 827132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 828132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 829132943Sgshapiro and -p port. This also allows for the use of LDAP over 830132943Sgshapiro SSL and connections via named sockets if your LDAP 831132943Sgshapiro library supports it. 832132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 833132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 834132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 835132943Sgshapiro during a SMTP session then terminate it just like it is 836132943Sgshapiro done for too many bad SMTP commands. 837132943Sgshapiro Basic connection rate control support has been added: the daemon 838132943Sgshapiro maintains the number of incoming connections per client 839132943Sgshapiro IP address and total in the macros {client_rate} and 840132943Sgshapiro {total_rate}, respectively. These macros can be used 841132943Sgshapiro in the cf file to impose connection rate limits. 842132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 843132943Sgshapiro determines the length of the interval for which the 844132943Sgshapiro number of connections is stored. Based on patch from 845132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 846132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 847132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 848132943Sgshapiro If enabled by the new ruleset greet_pause (see 849132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 850132943Sgshapiro amount of time before sending the initial 220 SMTP 851132943Sgshapiro greeting. If any traffic is received before then, a 554 852132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 853132943Sgshapiro during that connection. 854132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 855132943Sgshapiro server could sleep for a very long time. Fix based on 856132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 857132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 858132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 859132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 860132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 861132943Sgshapiro misinterpret it as a permanent error. 862132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 863132943Sgshapiro all milters accepted the mail. This can increase 864132943Sgshapiro performance if many mails are rejected by milters due to 865132943Sgshapiro body scans. Based on patch from David F. Skoll. 866132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 867132943Sgshapiro header, whether provided by the client or generated by 868132943Sgshapiro sendmail. 869132943Sgshapiro New macro {client_connections} which contains the number of open 870132943Sgshapiro connections in the SMTP server for the client IP address. 871132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 872132943Sgshapiro Mines de Paris. 873132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 874132943Sgshapiro to prevent confusion caused by running sendmail stop 875132943Sgshapiro scripts two or more times, where the second and subsequent 876141858Sgshapiro runs would report misleading error messages about sendmail's 877132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 878132943Sgshapiro for a discussion of the implications of this, including 879132943Sgshapiro how to correct broken scripts which may have depended on 880132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 881132943Sgshapiro Support per-daemon input filter lists which override the default 882132943Sgshapiro filter list specified in InputMailFilters. The filters 883132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 884132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 885132943Sgshapiro your configuration relies on this behavior, you have to 886132943Sgshapiro add those names to class 'w' yourself. Problem noted 887132943Sgshapiro by Sander Eerkes. 888132943Sgshapiro Support message quarantining in the mail queue. Quarantined 889132943Sgshapiro messages are not run on normal queue displays or runs 890132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 891132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 892132943Sgshapiro The -q command line option now can specify which queue to display 893132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 894132943Sgshapiro operates on lost queue items. 895132943Sgshapiro Restricted mail queue runs and displays can be done based on the 896132943Sgshapiro quarantined reason using -qQtext to run or display 897132943Sgshapiro quarantined items if the quarantine reason contains the 898132943Sgshapiro given text. Similarly, -q!Qtext will run or display 899132943Sgshapiro quarantined items which do not have the given text in the 900132943Sgshapiro quarantine reason. 901132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 902132943Sgshapiro new -Q option. See doc/op/op.me for more information. 903132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 904132943Sgshapiro quarantine reason is shown in a new line prefixed by 905132943Sgshapiro "QUARANTINE:". 906132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 907132943Sgshapiro to quarantine messages in check_* (except check_compat) and 908132943Sgshapiro header check rulesets. The $: of the mailer triplet will 909132943Sgshapiro be used for the quarantine reason. 910132943Sgshapiro Add a new quarantine count to the mailstats collected. 911132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 912132943Sgshapiro message if it is quarantined. 913132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 914132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 915132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 916132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 917132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 918132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 919132943Sgshapiro lookup for the client IP address. Note: this is the same 920132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 921132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 922132943Sgshapiro recipients received so far in a transaction. 923132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 924132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 925132943Sgshapiro noted by Kai Schlichting. 926132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 927132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 928132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 929132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 930132943Sgshapiro Wolfhugel of France Telecom Oleane. 931132943Sgshapiro Do not silently truncate long strings in address rewriting. 932132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 933132943Sgshapiro Oceana Matrix Ltd. 934132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 935132943Sgshapiro support mutual authentication. From Kenneth Murchison of 936132943Sgshapiro Oceana Matrix Ltd. 937132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 938132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 939132943Sgshapiro format just like the STARTTLS related macros to avoid 940132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 941132943Sgshapiro Masarati of SysNet s.n.c. 942132943Sgshapiro New option AuthRealm to set the authentication realm that is 943132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 944132943Sgshapiro of the University of Manitoba. 945132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 946132943Sgshapiro successful, otherwise relaying would be allowed if 947132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 948132943Sgshapiro is active. 949132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 950132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 951132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 952132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 953132943Sgshapiro DIGEST-MD5 and LOGIN. 954132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 955132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 956132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 957132943Sgshapiro overwrite each other's pid files. 958132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 959132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 960132943Sgshapiro Wolfhugel of France Telecom. 961132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 962132943Sgshapiro LogLevel 12 or higher. 963132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 964132943Sgshapiro try to use the SMTP command VERB to propagate this option 965132943Sgshapiro to the MTA which in turn will show the delivery just like 966132943Sgshapiro it was done before the default 8.12 separation of MSP and 967132943Sgshapiro MTA. Based on patch by Per Hedeland. 968132943Sgshapiro If a daemon is refusing connections for longer than the time specified 969132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 970132943Sgshapiro to high load, log this information. Patch from John Beck 971132943Sgshapiro of Sun Microsystems. 972132943Sgshapiro Remove the ability for non-trusted users to raise the value of 973132943Sgshapiro CheckpointInterval on the command line. 974132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 975132943Sgshapiro subset of the functionality of the 's' flag. 976132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 977132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 978132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 979132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 980132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 981132943Sgshapiro causing subsequent messages to be sent instead of being 982132943Sgshapiro discarded. This also caused milter callbacks to be called 983132943Sgshapiro out of order after the SMTP session was reset. 984132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 985132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 986132943Sgshapiro further information. 987132943Sgshapiro New command line option -D logfile to send debug output to 988132943Sgshapiro the indicated log file instead of stdout. 989132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 990132943Sgshapiro queue return and warning times for delivery status 991132943Sgshapiro notifications. 992132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 993132943Sgshapiro at all. 994132943Sgshapiro Several more return values for ruleset srv_features have been added 995132943Sgshapiro to enable/disable certain features in the server per 996132943Sgshapiro connection. See doc/op/op.me for details. 997132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 998132943Sgshapiro for DaemonPortOptions. 999132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 1000132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 1001132943Sgshapiro of Northern Illinois University. 1002132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 1003132943Sgshapiro be tried as a last resort after all other fallbacks. This 1004132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 1005132943Sgshapiro view of inside the company, but an incomplete view of 1006132943Sgshapiro outside). From John Beck of Sun Microsystems. 1007132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 1008132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 1009132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 1010132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 1011132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 1012132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 1013132943Sgshapiro of the University of Illinois at Urbana-Champaign. 1014132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 1015132943Sgshapiro applications for use in the xxfi_eom() callback. 1016132943Sgshapiro New macro {time} which contains the output of the time(3) function, 1017132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 1018132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 1019132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 1020132943Sgshapiro terminate the SMTP session with a 421 error message. 1021132943Sgshapiro Get rid of dead code that tried to access the environment variable 1022132943Sgshapiro HOSTALIASES. 1023132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 1024132943Sgshapiro compile with -DUSE_TTYPATH=1. 1025132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 1026132943Sgshapiro the header value passed in without balancing quotes, 1027132943Sgshapiro parentheses, and angle brackets. Based on patch from 1028132943Sgshapiro Oleg Bulyzhin. 1029132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 1030132943Sgshapiro angle brackets when reading in rulesets. This allows 1031132943Sgshapiro rules to be written for header checks to catch strings 1032132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 1033132943Sgshapiro Based on patch from Oleg Bulyzhin. 1034132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 1035132943Sgshapiro some temporary errors like ECONNABORTED. 1036132943Sgshapiro Added list of CA certificates that are used by members of the 1037132943Sgshapiro sendmail consortium, see CACerts. 1038132943Sgshapiro Portability: 1039132943Sgshapiro Two new compile options have been added: 1040132943Sgshapiro HASCLOSEFROM System has closefrom(3). 1041132943Sgshapiro HASFDWALK System has fdwalk(3). 1042132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 1043132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 1044132943Sgshapiro change to using fcntl() locking until they can fix 1045132943Sgshapiro it. Be sure to update other sendmail related 1046132943Sgshapiro programs to match locking techniques. 1047132943Sgshapiro New compile time option NEEDINTERRNO which should be set 1048132943Sgshapiro if <errno.h> does not declare errno itself. 1049132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 1050132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 1051132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 1052132943Sgshapiro Center for Scientific Computing. 1053132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 1054132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 1055132943Sgshapiro Remove path from compiler definition for Interix because 1056132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 1057132943Sgshapiro Also use <sys/mkdev.h> to get the correct 1058132943Sgshapiro major()/minor() definitions. Based on feedback 1059132943Sgshapiro from Mark Funkenhauser. 1060132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 1061132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 1062132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 1063132943Sgshapiro cf/sendmail.schema for more information. 1064132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 1065132943Sgshapiro is of the form "user:group" when used for submit.mc. 1066132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 1067132943Sgshapiro of Northern Illinois University. 1068132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 1069132943Sgshapiro instructs the check_* (except check_compat) to quarantine 1070132943Sgshapiro the message using the given reason. 1071132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 1072132943Sgshapiro instead of "host" to avoid problem with looking up other 1073132943Sgshapiro DNS records than just A. 1074132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 1075132943Sgshapiro length of the interval for which the number of incoming 1076132943Sgshapiro connections is maintained. 1077132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 1078132943Sgshapiro rate control for individual hosts or nets. 1079132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 1080132943Sgshapiro number of open SMTP connections for individual hosts or nets. 1081132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 1082132943Sgshapiro slamming protection described above. The feature can 1083132943Sgshapiro take an argument specifying the milliseconds to wait and/or 1084132943Sgshapiro use the access database to look the pause time based on 1085132943Sgshapiro client hostname, domain, IP address, or subnet. 1086132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 1087132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 1088132943Sgshapiro rejections based on the unverified hostname of client, 1089132943Sgshapiro which turns on the same behavior as in earlier sendmail 1090132943Sgshapiro versions when delay_checks was not in use. See also entry 1091132943Sgshapiro above about check_relay being invoked with ${client_name}. 1092132943Sgshapiro CONFIG: New option confREJECT_LOG_INTERVAL to specify the log 1093132943Sgshapiro interval when refusing connections for this long. 1094132943Sgshapiro CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases 1095132943Sgshapiro this requires a change in a mc file. Requested by 1096132943Sgshapiro Ted Roberts of Electronic Data Systems. 1097132943Sgshapiro CONFIG: New option confAUTH_REALM to set the authentication realm 1098132943Sgshapiro that is passed to the Cyrus SASL library.

See cf/README for more information. 1130132943Sgshapiro CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which 1131132943Sgshapiro instructs the rulesets on whether or not to do a domain 1132132943Sgshapiro lookup if a full address lookup doesn't match. See cf/README 1133132943Sgshapiro for more information. 1134132943Sgshapiro CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which 1135132943Sgshapiro instructs the rulesets on whether or not to queue the mail 1136132943Sgshapiro or give an SMTP temporary error if the LDAP server can't be 1137132943Sgshapiro reached. See cf/README for more information. Based on 1138132943Sgshapiro patch from Billy Ray Miller of Caterpillar. 1139132943Sgshapiro CONFIG: Experimental support for MTAMark, see cf/README for details. 1140132943Sgshapiro CONFIG: New option confMESSAGEID_HEADER to define a different 1141132943Sgshapiro Message-Id: header format. Patch from Bastiaan Bakker 1142132943Sgshapiro of LifeLine Networks. 1143132943Sgshapiro CONTRIB: New version of cidrexpand which uses Net::CIDR. From 1144132943Sgshapiro Derek J. Balling. 1145132943Sgshapiro CONTRIB: oldbind.compat.c has been removed due to security problems. 1146132943Sgshapiro Found by code inspection done by Reasoning, Inc. 1147132943Sgshapiro DEVTOOLS: Add an example file for devtools/Site/, contributed 1148132943Sgshapiro by Neil Rickert of Northern Illinois University. 1149132943Sgshapiro LIBMILTER: Add new function smfi_quarantine() which allows the 1150132943Sgshapiro filter's EOM routine to quarantine the current message. 1151132943Sgshapiro Filters which use this function must include the 1152132943Sgshapiro SMFIF_QUARANTINE flag in the registered smfiDesc structure. 1153132943Sgshapiro LIBMILTER: If a milter sets the reply code to "421", the SMTP server 1154132943Sgshapiro will terminate the SMTP session with that error. 1155132943Sgshapiro LIBMILTER: Upon filter shutdown, libmilter will not remove a 1156132943Sgshapiro named socket in the file system if it is running as root. 1157132943Sgshapiro LIBMILTER: Add new function smfi_progress() which allows the filter 1158132943Sgshapiro to notify the MTA that an EOM operation is still in progress, 1159132943Sgshapiro resetting the timeout. 1160132943Sgshapiro LIBMILTER: Add new function smfi_opensocket() which allows the filter 1161132943Sgshapiro to attempt to establish the interface socket, and detect 1162132943Sgshapiro failure to do so before calling smfi_main(). 1163132943Sgshapiro LIBMILTER: Add new function smfi_setmlreply() which allows the 1164132943Sgshapiro filter to return a multi-line SMTP reply. 1165132943Sgshapiro LIBMILTER: Deal with more temporary errors in accept() by ignoring 1166132943Sgshapiro them instead of stopping after too many occurred. 1167132943Sgshapiro Suggested by James Carlson of Sun Microsystems. 1168132943Sgshapiro LIBMILTER: Fix a descriptor leak in the sample program found in 1169132943Sgshapiro docs/sample.html.

If you do not use IPv4 but only IPv6 then 1492110560Sgshapiro you need to change submit.mc accordingly, see the comment 1493110560Sgshapiro in the file itself. 1494110560Sgshapiro CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid 1495110560Sgshapiro error messages from initgroups(3) on AIX 4.3 when sending 1496110560Sgshapiro mail to non-existing users. Problem noted by Mark Roth of 1497110560Sgshapiro the University of Illinois at Urbana-Champaign. 1498110560Sgshapiro CONFIG: Allow local_procmail to override local_lmtp settings. 1499110560Sgshapiro CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to 1500110560Sgshapiro relay. 1501110560Sgshapiro CONTRIB: cidrexpand: Deal with the prefix tags that may be included 1502110560Sgshapiro in access_db. 1503110560Sgshapiro CONTRIB: New version of doublebounce.pl contributed by Leo Bicknell. 1504110560Sgshapiro LIBMILTER: On Solaris libmilter may get into an endless loop if 1505110560Sgshapiro an error in the communication from/to the MTA occurs. 1506110560Sgshapiro Patch from Gurusamy Sarathy of Active State. 1507110560Sgshapiro LIBMILTER: Ignore EINTR from sigwait(3) which may happen on Tru64. 1508110560Sgshapiro Patch from from Jose Marcio Martins da Cruz of Ecole 1509110560Sgshapiro Nationale Superieure des Mines de Paris. 1510110560Sgshapiro MAIL.LOCAL: Fix a truncation race condition if the close() on 1511110560Sgshapiro the mailbox fails.

Problem 1553102528Sgshapiro noted by Ian Duplisse of Cable Television Laboratories, Inc. 1554102528Sgshapiro If discarding a message based on a recipient, don't try to look up 1555102528Sgshapiro the recipient in the mailbox database if F=w is set. This 1556102528Sgshapiro allows users to discard bogus recipients when dealing with 1557102528Sgshapiro spammers without tipping them off. Problem noted by Neil 1558102528Sgshapiro Rickert of Northern Illinois University. 1559102528Sgshapiro If applying a header check to a header with unstructured data, 1560102528Sgshapiro e.g., Subject:, then do not run syntax checks that are 1561102528Sgshapiro supposed for addresses on the header content. 1562102528Sgshapiro Count messages rejected/discarded via the check_data ruleset. 1563102528Sgshapiro Portability: 1564102528Sgshapiro Fix compilation on systems which do not allow simple 1565102528Sgshapiro copying of the variable argument va_list. Based on 1566102528Sgshapiro fix from Scott Walters. 1567102528Sgshapiro Fix NSD map open bug. From Michel Bourget of SGI. 1568102528Sgshapiro Add some additional IRIX shells to the default shell 1569102528Sgshapiro list. From Michel Bourget of SGI. 1570102528Sgshapiro Fix compilation issues on Mac OS X 10.2 (Darwin 6.0). 1571102528Sgshapiro NETISO support has been dropped. 1572102528Sgshapiro CONFIG: There was a seemingly minor change in 8.12.4 with respect 1573102528Sgshapiro to handling entries of IP nets/addresses with RHS REJECT. 1574102528Sgshapiro These would be rejected in check_rcpt instead of only 1575102528Sgshapiro being activated in check_relay. This change has been made to 1576102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 1577102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 1578102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1579102528Sgshapiro modification causes a change of behavior if an IP net/address 1580102528Sgshapiro is listed in the access map with REJECT and a host/domain 1581102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1582102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1583102528Sgshapiro change was made on request of Neil Rickert of Northern 1584102528Sgshapiro Illinois University, the side effect has been found by 1585102528Sgshapiro Stefaan Van Hoornick. 1586102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1587102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1588102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1589102528Sgshapiro University. 1590102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1591102528Sgshapiro Fix from Andrzej Filip. 1592102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1593102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1594102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1595102528Sgshapiro NULL pointer.

None of the 160698841Sgshapiro sendmail supplied configuration files use this option hence 160798841Sgshapiro they are not vulnerable. Problem noted independently by 160898841Sgshapiro Joost Pol of PINE Internet and Anton Rang of Sun Microsystems. 160998841Sgshapiro Unprintable characters in responses from DNS servers for the DNS 161098841Sgshapiro map type are changed to 'X' to avoid potential problems 161198841Sgshapiro with rogue DNS servers. 161298841Sgshapiro Require a suboption when setting the Milter option. Problem noted 161398841Sgshapiro by Bryan Costales. 161498841Sgshapiro Do not silently overwrite command line settings for 161598841Sgshapiro DirectSubmissionModifiers. Problem noted by Bryan 161698841Sgshapiro Costales. 161798841Sgshapiro Prevent a segmentation fault when clearing the event list by 161898841Sgshapiro turning off alarms before checking if event list is 161998841Sgshapiro empty. Problem noted by Allan E Johannesen of Worcester 162098841Sgshapiro Polytechnic Institute. 162198841Sgshapiro Close a potential race condition in transitioning a memory buffered 162298841Sgshapiro file onto disk. From Janani Devarajan of Sun Microsystems. 162398841Sgshapiro Portability: 162498841Sgshapiro Include paths.h on Linux systems running glibc 2.0 or later 162598841Sgshapiro to get the definition for _PATH_SENDMAIL, used by 162698841Sgshapiro rmail and vacation. Problem noted by Kevin 162798841Sgshapiro A. McGrail of Peregrine Hardware. 162898841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 162998841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 163098841Sgshapiro 8.13 will change the default locking method to 163198841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 163298841Sgshapiro want to do this in 8.12 by compiling with 163398841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 163498841Sgshapiro related programs to match locking techniques. 163598841Sgshapiro 163698121Sgshapiro8.12.4/8.12.4 2002/06/03 163798121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 163898121Sgshapiro can leave systems open to a local denial of service 163998121Sgshapiro attack.

In previous versions this could cause mail 173294334Sgshapiro not to be delivered if a queue file is repeatedly moved 173394334Sgshapiro by an external process whenever sendmail moved it back 173494334Sgshapiro into the right place. Some precautions have been taken 173594334Sgshapiro to avoid moving queue files if not really necessary. 173694334Sgshapiro sendmail may use links to refer to queue files and it 173794334Sgshapiro may store the path of data files in queue files. Hence 173894334Sgshapiro queue files should not be moved unless those internals 173994334Sgshapiro are understood and the integrity of the files is not 174094334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 174194334Sgshapiro University. 174294334Sgshapiro If an error mail is created, and the mail is split across different 174394334Sgshapiro queue directories, and SuperSafe is off, then write the mail 174494334Sgshapiro to disk before splitting it, otherwise an assertion is 174594334Sgshapiro triggered.

Based on 181794334Sgshapiro patch by Bryan Costales. 181894334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 181994334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 182094334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 182194334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 182294334Sgshapiro errors. By doing so, the host was marked as having a 182394334Sgshapiro temporary problem and other mail destined for that host was 182494334Sgshapiro queued for the next queue run. Problem noted by Fletcher 182594334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 182694334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 182794334Sgshapiro and Neil Rickert of Northern Illinois University. 182894334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 182994334Sgshapiro which drop the connection instead of responding to the 183094334Sgshapiro command). 183194334Sgshapiro Portability: 183294334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 183398121Sgshapiro available. 183494334Sgshapiro Define HPUX10 when building on HP-UX 10.X.

From 184294334Sgshapiro Rajesh Somasund of Hewlett-Packard. 184394334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 184494334Sgshapiro SMTP AUTH information. This feature was actually added in 184594334Sgshapiro 8.12.0 but a release note was not included. 184694334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 184794334Sgshapiro parameter is set and the LDAP lookup returns a temporary 184894334Sgshapiro error. 184994334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 185094334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 185194334Sgshapiro Krzysztof Oledzki. 185294334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 185394334Sgshapiro initialization as aliases are not needed for the MSP. 185494334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 185594334Sgshapiro is in use. Patch from Andrzej Filip. 185694334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 185794334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 185894334Sgshapiro This will only have an effect if a parameter is specified, 185994334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 186094334Sgshapiro it is embedded in square brackets. Problem noted by 186194334Sgshapiro Theo Van Dinter of Collective Technologies. 186294334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 186394334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 186494334Sgshapiro to allow for the proper time zone on systems where the 186594334Sgshapiro default results in misleading time stamps. That is, syslog 186694334Sgshapiro time stamps and Date headers on submitted mail will use the 186794334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 186894334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 186994334Sgshapiro by Neil Rickert of Northern Illinois University. 187094334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 187194334Sgshapiro binary.

Problem noted by Brad Chapman. 208190792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 208290792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 208390792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 208490792Sgshapiro this only applied to hostname canonification. Problem 208590792Sgshapiro noted by Bill Fenner of AT&T Research. 208690792Sgshapiro Ignore comments in NIS host records when trying to find the 208790792Sgshapiro canonical name for a host. 208890792Sgshapiro When sendmail has extra privileges, limit mail submission command 208990792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 209090792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 209190792Sgshapiro suggestion from Michal Zalewski. 209290792Sgshapiro Portability: 209390792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 209490792Sgshapiro `uname` does not given complete information. 209590792Sgshapiro Problem noted by Keith Neufeld of the Cessna 209690792Sgshapiro Aircraft Company. 209790792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 209890792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 209990792Sgshapiro Avoid compiler warnings by not using pointers to pass 210090792Sgshapiro integers. Problem noted by Todd C. Miller of 210190792Sgshapiro Courtesan Consulting. 210290792Sgshapiro CONFIG: Add restrictqrun to PrivacyOptions for the MSP to minimize 210390792Sgshapiro problems with potential misconfigurations. 210490792Sgshapiro CONFIG: Fix comment showing default value of MaxHopCount. Problem 210590792Sgshapiro noted by Greg Robinson of the Defence Science and 210690792Sgshapiro Technology Organisation of Australia. 210790792Sgshapiro CONFIG: dnsbl: If an argument specifies an error message in case 210890792Sgshapiro of temporary lookup failures for DNS based blacklists 210990792Sgshapiro then use it. 211090792Sgshapiro LIBMILTER: Install mfdef.h, required by mfapi.h. Problem noted by 211190792Sgshapiro Richard A. Nelson of Debian. 211290792Sgshapiro LIBMILTER: Add __P definition for OS that lack it. Problem noted 211390792Sgshapiro by Chris Adams from HiWAAY Informations Services. 211490792Sgshapiro LIBSMDB: Fix a lock race condition that affects makemap, praliases, 211590792Sgshapiro and vacation. 211690792Sgshapiro MAKEMAP: Avoid going beyond the end of an input line if it does 211790792Sgshapiro not contain a value for a key.

You need to create a new user and 213390792Sgshapiro a new group before installing sendmail (both called smmsp by 213490792Sgshapiro default). The installation process tries to install 213590792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 213690792Sgshapiro default.

Suggested 214790792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 214890792Sgshapiro (IdS). 214990792Sgshapiro Fixed problem of a global variable being used for a timeout jump 215090792Sgshapiro point where the variable could become overused for more than 215190792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 215290792Sgshapiro a corrupted stack causing a core dump. The timeout is now 215390792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 215490792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 215590792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 215690792Sgshapiro checks (group ID of RunAsUser). This allows use of a 215790792Sgshapiro set-group-ID sendmail binary for initial message submission 215890792Sgshapiro and no set-user-ID root sendmail is needed. For details 215990792Sgshapiro see sendmail/SECURITY. 216090792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 216190792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 216290792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 216390792Sgshapiro with a fallback of sendmail.cf as configuration file. See 216490792Sgshapiro sendmail/SECURITY. 216590792Sgshapiro New configuration file option UseMSP to allow group writable queue 216690792Sgshapiro files if the group is the same as that of a set-group-ID 216790792Sgshapiro sendmail binary. See sendmail/SECURITY. 216890792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 216990792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 217090792Sgshapiro is sendmail.cf (to be backward compatible). This selection 217190792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 217290792Sgshapiro file: client or mta). See sendmail/SECURITY. 217390792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 217490792Sgshapiro command has been removed. 217590792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 217690792Sgshapiro at compile time or per host (ruleset). 217790792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 217890792Sgshapiro used to look up local mail recipients; the default value 217990792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 218090792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 218190792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 218290792Sgshapiro long, to accomodate envelope splitting. File systems with 218390792Sgshapiro a 14 character file name length limit are no longer 218490792Sgshapiro supported. 218590792Sgshapiro Recipient list used for delivery now gets internally ordered by 218690792Sgshapiro hostsignature (character string version of MX RR). This orders 218790792Sgshapiro recipients for the same MX RR's together meaning smaller 218890792Sgshapiro portions of the list need to be scanned (instead of the whole 218990792Sgshapiro list) each delivery() pass to determine piggybacking. The 219090792Sgshapiro significance of the change is better the larger the recipient 219190792Sgshapiro list. Hostsignature is now created during recipient list 219290792Sgshapiro creation rather than just before delivery. 219390792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 219490792Sgshapiro piggybacking (called coincidental) extended to coattail 219590792Sgshapiro piggybacking. Rather than complete MX RR matching 219690792Sgshapiro (coincidental) piggybacking is done if just the lowest value 219790792Sgshapiro preference matches (coattail). 219890792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 219990792Sgshapiro try other MX hosts if available. 220090792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 220190792Sgshapiro outgoing (client-side) SMTP Authentication. 220290792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 220390792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 220490792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 220590792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 220690792Sgshapiro A new ruleset authinfo can be used to return client side 220790792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 220890792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 220990792Sgshapiro removed in future versions. 221090792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 221190792Sgshapiro requires 334. Mercury 1.48 is a known offender. 221290792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 221390792Sgshapiro for the security layer in SMTP AUTH (SASL). See 221490792Sgshapiro doc/op/op.me for details. 221590792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 221690792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 221790792Sgshapiro signed the presented certificate, the CN and the MD5 hash 221890792Sgshapiro of the presented certificate, respectively. 221990792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 222090792Sgshapiro New ruleset srv_features to enable/disable certain features in the 222190792Sgshapiro server per connection. See doc/op/op.me for details. 222290792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 222390792Sgshapiro recipient; useful to decide whether a conection is secure 222490792Sgshapiro enough on a per recipient basis. 222590792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 222690792Sgshapiro for STARTTLS. 222790792Sgshapiro If no certificate has been requested, the macro {verify} has the 222890792Sgshapiro value "NOT". 222990792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 223090792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 223190792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 223290792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 223390792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 223490792Sgshapiro really required. This change results in a noticable 223590792Sgshapiro performance gains on most machines. Moreover, if shared 223690792Sgshapiro memory is in use, reuse the key several times. 223790792Sgshapiro Add queue groups which can be used to group queue directories with 223890792Sgshapiro the same behavior together. See doc/op/op.me for details. 223990792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 224090792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 224190792Sgshapiro are initially sorted which may result in faster envelope 224290792Sgshapiro splitting. If the mail is submitted directly from the 224390792Sgshapiro command line, then the value also limits the number of 224490792Sgshapiro processes to deliver the envelopes; if more envelopes are 224590792Sgshapiro created they are only queued up and must be taken care of 224690792Sgshapiro by a queue run. 224790792Sgshapiro The check for 'enough disk space' now pays attention to which file 224890792Sgshapiro system each queue directory resides in. 224990792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 225090792Sgshapiro New option QueueFileMode for the default permissions of queue files. 225190792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 225290792Sgshapiro group (one or more queues in a multi-queue environment 225390792Sgshapiro collected together) to process the same work list at the 225490792Sgshapiro same time. 225590792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 225690792Sgshapiro active queue runner processes. 225790792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 225890792Sgshapiro runners per queue group. 225990792Sgshapiro Queue member selection by substring pattern matching now allows 226090792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 226190792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 226290792Sgshapiro of the queue that match during processing. 226390792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 226490792Sgshapiro periodically forking a child to process the queue, a single 226590792Sgshapiro child is forked for each queue that sleeps between queue 226690792Sgshapiro runs. A SIGHUP signal can be sent to restart this 226790792Sgshapiro persistent queue runner. 226890792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 226990792Sgshapiro sendmail process which only runs the queue at an interval: 227090792Sgshapiro sendmail -q15m). 227190792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 227290792Sgshapiro Proposed by Thom O'Connor. 227390792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 227490792Sgshapiro unless the new -qf option or -v is used. 227590792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 227690792Sgshapiro several queue runners are started by hand to avoid contention. 227790792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 227890792Sgshapiro of the qf file (older entries first). 227990792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 228090792Sgshapiro a client to specify an amount of time within which an e-mail 228190792Sgshapiro should be delivered. New option DeliverByMin added to set the 228290792Sgshapiro minimum amount of time or disable the extension. 228390792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 228490792Sgshapiro not allowed unless escaped or quoted. 228590792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 228690792Sgshapiro by Leif Johansson of Stockholm University, which was based on 228790792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 228890792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 228990792Sgshapiro Technology, Stockholm, Sweden. 229090792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 229190792Sgshapiro behavior (no MX lookups), put the name in square brackets. 229290792Sgshapiro Proposed by Thom O'Connor. 229390792Sgshapiro Use shared memory to store free space of filesystems that are used 229490792Sgshapiro for queues, if shared memory is available and if a key is set 229590792Sgshapiro via SharedMemoryKey. This minimizes the number of system 229690792Sgshapiro calls to check the available space. See doc/op/op.me for 229790792Sgshapiro details. 229890792Sgshapiro If shared memory is compiled in the option -bP can be used to print 229990792Sgshapiro the number of entries in the queue(s). 230090792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 230190792Sgshapiro and the usual documentation for details. 230290792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 230390792Sgshapiro Remove '-U' (initial user submission) command line option as 230490792Sgshapiro announced in 8.10. 230590792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 230690792Sgshapiro New macro {addr_type} which contains whether the current address is 230790792Sgshapiro an envelope sender or recipient address. Suggested by 230890792Sgshapiro Neil Rickert of Northern Illinois University. 230990792Sgshapiro Two new options for host maps: -d (retransmission timeout), 231090792Sgshapiro -r (number of retries). 231190792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 231290792Sgshapiro separator such that a lookup can return both an attribute 231390792Sgshapiro and value separated by the given separator. 231490792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 231590792Sgshapiro to map class arith. 231690792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 231790792Sgshapiro (errors that occur when sending an error message) are dropped. 231890792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 231990792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 232090792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 232190792Sgshapiro requirements for files containing secret keys. This is 232290792Sgshapiro necessary for the MSP if client authentification is used. 232390792Sgshapiro Properly handle quoted filenames for class files (to allow for 232490792Sgshapiro filenames with spaces). 232590792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 232690792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 232790792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 232890792Sgshapiro {if_addr_out} address of interface of outgoing connection. 232990792Sgshapiro {if_family_out} family of interface of outgoing connection. 233090792Sgshapiro The latter two are only set if the interface does not belong 233190792Sgshapiro to the loopback net. 233290792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 233390792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 233490792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 233590792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 233690792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 233790792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 233890792Sgshapiro all connections for a single delivery attempt to succeed. 233990792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 234090792Sgshapiro a threshold number of recipients has been rejected (option 234190792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 234290792Sgshapiro Development Group. 234390792Sgshapiro New option DelayLA to delay connections if the load averages 234490792Sgshapiro exceeds the specified value. The default of 0 does not 234590792Sgshapiro change the previous behavior. A value greater than 0 234690792Sgshapiro will cause sendmail to sleep for one second on most 234790792Sgshapiro SMTP commands and before accepting connections if that 234890792Sgshapiro load average is exceeded. 234990792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 235090792Sgshapiro recipients that are sent during a connection to a mailer. 235190792Sgshapiro This also introduces a new mailer field 'r' which defines 235290792Sgshapiro the maximum number of recipients (defaults to 100). 235390792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 235490792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 235590792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 235690792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 235790792Sgshapiro instead. 235890792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 235990792Sgshapiro builtin mailer pathnames. Use TCP instead. 236090792Sgshapiro PH map code updated to use the new libphclient API instead of the 236190792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 236290792Sgshapiro University of Illinois at Urbana-Champaign. 236390792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 236490792Sgshapiro for direct (command line) submissions. 236590792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 236690792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 236790792Sgshapiro Hagino of the KAME Project. 236890792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 236990792Sgshapiro whose content is rewritten similar to Reply-To:. 237090792Sgshapiro Proposed by Andrzej Filip. 237190792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 237290792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 237390792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 237490792Sgshapiro AUTH/STARTTLS related logfile entries. 237590792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 237690792Sgshapiro before logging. 237790792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 237890792Sgshapiro (at LogLevel 9/10 or higher). 237990792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 238090792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 238190792Sgshapiro in which most commands are rejected due to check_relay or 238290792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 238390792Sgshapiro Change logging format for cloned envelopes to be similar to that for 238490792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 238590792Sgshapiro of the Universitat Regensburg. 238690792Sgshapiro Added libsm, a C library of general purpose abstractions including 238790792Sgshapiro assertions, tracing and debugging with named debug categories, 238890792Sgshapiro exception handling, malloc debugging, resource pools, 238990792Sgshapiro portability abstractions, and an extensible buffered I/O 239090792Sgshapiro package. It will at some point replace libsmutil. 239190792Sgshapiro See libsm/index.html for details. 239290792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 239390792Sgshapiro care of by fork() and exit(). 239490792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 239590792Sgshapiro more consistent portablity amongst different platforms 239690792Sgshapiro new and old (from new libsm). 239790792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 239890792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 239990792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 240090792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 240190792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 240290792Sgshapiro synchronizations calls. 240390792Sgshapiro Add per-recipient status information to mailq -v output. 240490792Sgshapiro T_ANY queries are no longer used by sendmail. 240590792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 240690792Sgshapiro too (see include/sm/cdefs.h for more info). 240790792Sgshapiro sendmail -d now has general support for named debug categories. 240890792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 240990792Sgshapiro for details. 241090792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 241190792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 241290792Sgshapiro generated by this condition were illegal (not RFC conform). 241390792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 241490792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 241590792Sgshapiro mailer and the recipient has hence been rejected during the 241690792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 241790792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 241890792Sgshapiro that do not have postmaster defined. If an email was sent 241990792Sgshapiro from an address to which a DSN cannot be returned and 242090792Sgshapiro in which at least one recipient address is non-deliverable, 242190792Sgshapiro then that email had been delivered in each queue run. 242290792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 242390792Sgshapiro degli Studi dell'Insubria. 242490792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 242590792Sgshapiro i.e., the corresponding code is always compiled in now. 242690792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 242790792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 242890792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 242990792Sgshapiro attempting to canonify a hostname, some broken nameservers 243090792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 243190792Sgshapiro lookups. If you want to excuse this behavior, use this new 243290792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 243390792Sgshapiro Mark Roth of the University of Illinois at 243490792Sgshapiro Urbana-Champaign. 243590792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 243690792Sgshapiro noted by Joy Latten of IBM. 243790792Sgshapiro ConnectionRateThrottle limits the number of connections per second 243890792Sgshapiro to each daemon individually, not the overall number of 243990792Sgshapiro connections. 244090792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 244190792Sgshapiro sendmail to use a default alias schema as outlined in the 244290792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 244390792Sgshapiro cf/README. 244490792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 244590792Sgshapiro the first character after the class name is not a '/' or a 244690792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 244790792Sgshapiro rest of the line will be parsed as a map lookup. This 244890792Sgshapiro allows classes to be filled via a map lookup. See op.me 244990792Sgshapiro for more syntax information. Specifically, this can be 245090792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 245190792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 245290792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 245390792Sgshapiro example). 245490792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 245590792Sgshapiro the default schema used in the above two items. 245690792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 245790792Sgshapiro warning if a program being run from a mailer or file class 245890792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 245990792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 246090792Sgshapiro if a program being run from a mailer or file class 246190792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 246290792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 246390792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 246490792Sgshapiro (without quotes) will disable this and return to the 246590792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 246690792Sgshapiro Suggested by Bryan Stansell of GNAC. 246790792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 246890792Sgshapiro HELO/EHLO commands. 246990792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 247090792Sgshapiro possible protocol family which may be used for outgoing 247190792Sgshapiro connections. Restrictions placed on one family only affect 247290792Sgshapiro outgoing connections on that particular family. Because of 247390792Sgshapiro this change, the ${client_flags} macro is not set until the 247490792Sgshapiro connection is established. Based on patch from Motonori 247590792Sgshapiro Nakamura of Kyoto University. 247690792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 247790792Sgshapiro when the -bv option is given by users who are neither root 247890792Sgshapiro nor the TrustedUser so users can not read private aliases, 247990792Sgshapiro forwards, or :include: files. It also will override the -v 248090792Sgshapiro (verbose) command line option. 248190792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 248290792Sgshapiro address can't be used for the outgoing connection, fall 248390792Sgshapiro back to the settings in ClientPortOptions (if set). 248490792Sgshapiro Problem noted by John Beck of Sun Microsystems. 248590792Sgshapiro New named config file rule check_data for DATA command (input: 248690792Sgshapiro number of recipients). Based on patch from Mark Roth of 248790792Sgshapiro the University of Illinois at Urbana-Champaign. 248890792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 248990792Sgshapiro can be specified using the '#' option character. For 249090792Sgshapiro example, 'ETRN #queuegroup'. 249190792Sgshapiro If an LDAP server times out or becomes unavailable, close the 249290792Sgshapiro current connection and reopen to get to one of the fallback 249390792Sgshapiro servers. Patch from Paul Hilchey of the University of 249490792Sgshapiro British Columbia. 249590792Sgshapiro Make default error number on $#error messages 550 instead of 501 249690792Sgshapiro because 501 is not allowed on all commands. 249790792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 249890792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 249990792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 250090792Sgshapiro if required. 250190792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 250290792Sgshapiro class instead. 250390792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 250490792Sgshapiro "IPv6:" tag to identify the address properly. For example, 250590792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 250690792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 250790792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 250890792Sgshapiro MTA is running. For example, during a queue run. 250990792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 251090792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 251190792Sgshapiro Nelson of IBM. 251290792Sgshapiro The maximum number of commands before the MTA slows down when too 251390792Sgshapiro many "light weight" commands have been received are now 251490792Sgshapiro configurable during compile time. The current values and 251590792Sgshapiro their defaults are: 251690792Sgshapiro MAXBADCOMMANDS 25 unknown commands 251790792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 251890792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 251990792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 252090792Sgshapiro MAXETRNCOMMANDS 8 ETRN 252190792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 252290792Sgshapiro Costales of SL3D, Inc. 252390792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 252490792Sgshapiro ${MyMacro} is defined but also that it is not empty. 252590792Sgshapiro Properly quote usernames with special characters if they are used 252690792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 252790792Sgshapiro Meteorological Institute. 252890792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 252990792Sgshapiro messages for messages for mailing list expanded addresses 253090792Sgshapiro which are not delivered on the initial attempt. 253190792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 253290792Sgshapiro the final dot has been sent to avoid affecting future 253390792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 253490792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 253590792Sgshapiro file systems that require to call fsync() for a directory 253690792Sgshapiro if the meta-data in it has been changed. This should be 253790792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 253890792Sgshapiro See sendmail/README for further information. 253990792Sgshapiro Avoid file locking deadlock when updating the statistics file if 254090792Sgshapiro sendmail is signaled to terminate. Problem noted by 254190792Sgshapiro Christophe Wolfhugel of France Telecom. 254290792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 254390792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 254490792Sgshapiro the Finnish Meteorological Institute. 254590792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 254690792Sgshapiro from Peter A. Friend of EarthLink. 254790792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 254890792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 254990792Sgshapiro flora.ca. 255090792Sgshapiro Portability: 255190792Sgshapiro Remove support for AIX 2, which supports only 14 character 255290792Sgshapiro filenames and is outdated anyway. Suggested by 255390792Sgshapiro Valdis Kletnieks of Virginia Tech. 255490792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 255590792Sgshapiro i.e., use default /usr/sbin, change owner/group 255690792Sgshapiro of man pages and user-executable to root/sys, set 255790792Sgshapiro optimization limit to 0 (unlimited). Based on patch 255890792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 255990792Sgshapiro Hurtta of the Finnish Meteorological Institute. 256090792Sgshapiro Do not assume LDAP support is installed by default under 256190792Sgshapiro Solaris 8 and later. 256290792Sgshapiro Add support for OpenUNIX. 256390792Sgshapiro CONFIG: Increment version number of config file to 10. 256490792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 256590792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 256690792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 256790792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 256890792Sgshapiro temporary lookup failures. 256990792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 257090792Sgshapiro action to be taken by aborting the search for domain names 257190792Sgshapiro or IP nets. 257290792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 257390792Sgshapiro relay address as long as the other part allows the email 257490792Sgshapiro to get through. 257590792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 257690792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 257790792Sgshapiro entry like user+*@domain. This allows handling of details by 257890792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 257990792Sgshapiro introduced to match only non-empty details of addresses. 258090792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 258190792Sgshapiro and hence there is no required order within the MAILER 258290792Sgshapiro section anymore except for MAILER(`uucp') which must come 258390792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 258490792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 258590792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 258690792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 258790792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 258890792Sgshapiro in the access map which returns OK or RELAY actually 258990792Sgshapiro terminates check_* ruleset checking. 259090792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 259190792Sgshapiro tls_rcpt, see cf/README for details. 259290792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 259390792Sgshapiro STARTTLS has been used to "(version=${tls_version} 259490792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 259590792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 259690792Sgshapiro options friends/haters instead of "To:" and enable 259790792Sgshapiro specification of whole domains instead of just users. 259890792Sgshapiro Notice: this change is not backward compatible. 259990792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 260090792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 260190792Sgshapiro cf/README for details. 260290792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 260390792Sgshapiro the access map. Proposed by Randall Winchester of the 260490792Sgshapiro University of Maryland. 260590792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 260690792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 260790792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 260890792Sgshapiro messages for an unauthorized relaying attempt/for access 260990792Sgshapiro map entries with RHS REJECT, respectively. 261090792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 261190792Sgshapiro to specify another domain to be added instead of the local one. 261290792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 261390792Sgshapiro Solving. 261490792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 261590792Sgshapiro options, see doc/op/op.me for details. 261690792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 261790792Sgshapiro the security layer in SMTP AUTH (SASL). 261890792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 261990792Sgshapiro immediately. 262090792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 262190792Sgshapiro allows checking of the return values of the DNS lookups. 262290792Sgshapiro See cf/README for details. 262390792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 262490792Sgshapiro temporary lookup failures. 262590792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 262690792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 262790792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 262890792Sgshapiro memory use. 262990792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 263090792Sgshapiro of the sender and the recipient address delimited by the 263190792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 263290792Sgshapiro in the access map. Based on code contributed by Mathias 263390792Sgshapiro Koerber of Singapore Telecommunications Ltd. 263490792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 263590792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 263690792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 263790792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 263890792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 263990792Sgshapiro the recipient host if LUSER_RELAY is used. 264090792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 264190792Sgshapiro +detail portion of the address when passing address to 264290792Sgshapiro local delivery agent. Disables alias and .forward +detail 264390792Sgshapiro stripping. Only use if LDA supports this. 264490792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 264590792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 264690792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 264790792Sgshapiro Routing lookups. Equivalent hostnames are replaced by the 264890792Sgshapiro masquerade domain name for lookups. See cf/README for 264990792Sgshapiro additional details. 265090792Sgshapiro CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which 265190792Sgshapiro instructs the rulesets on what to do if the address being 265290792Sgshapiro looked up has +detail information. See cf/README for more 265390792Sgshapiro information. 265490792Sgshapiro CONFIG: When chosing a new destination via LDAP Routing, also look 265590792Sgshapiro up the new routing address/host in the mailertable.

If sendmail needs to drop 329464562Sgshapiro these privileges and the operating system doesn't set the 329564562Sgshapiro saved-uid as well, exit with an error. Problem noted by 329664562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 329764562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 329864562Sgshapiro it populates. It is possible that some broken 329964562Sgshapiro implementations of snprintf() exist that do not do this. 330064562Sgshapiro Systems in this category should compile with 330164562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 330264562Sgshapiro system and report broken implementations to 330364562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 330464562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 330564562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 330664562Sgshapiro Implementation influenced by the example programs of 330764562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 330864562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 330964562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 331064562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 331164562Sgshapiro cf/README and doc/op/op.*. 331264562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 331364562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 331464562Sgshapiro ${server_name}, and ${server_addr}. These are documented 331564562Sgshapiro in cf/README and doc/op/op.*. 331664562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 331764562Sgshapiro random data. 331864562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 331964562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 332064562Sgshapiro try to use STARTTLS despite the security problems. 332164562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 332264562Sgshapiro support encryption. Based on code contributed by Tim 332364562Sgshapiro Martin of CMU. 332464562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 332564562Sgshapiro strength factor. 332664562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 332764562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 332864562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 332964562Sgshapiro of CMU. 333064562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 333164562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 333264562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 333364562Sgshapiro Fix the default family selection for DaemonPortOptions. As 333464562Sgshapiro documented, unless a family is specified in a 333564562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 333664562Sgshapiro also the default if no DaemonPortOptions value is set. 333764562Sgshapiro Therefore, IPv6 users should configure additional sockets 333864562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 333964562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 334064562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 334164562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 334264562Sgshapiro the interface information for an outgoing connection. 334364562Sgshapiro Not doing so was creating a mismatch between the socket 334464562Sgshapiro family and address used in subsequent connections if the 334564562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 334664562Sgshapiro by John Beck of Sun Microsystems. 334764562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 334864562Sgshapiro family based on the IP address. ${if_family} is no longer 334964562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 335064562Sgshapiro of Sun Microsystems. 335164562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 335264562Sgshapiro macros for both the incoming interface address/family and 335364562Sgshapiro the outgoing interface address/family. In order for M=b 335464562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 335564562Sgshapiro the incoming information in the queue file for later 335664562Sgshapiro delivery attempts. 335764562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 335864562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 335964562Sgshapiro smoe.org. 336064562Sgshapiro Add more vigilance in checking for putc() errors on output streams 336164562Sgshapiro to protect from a bug in Solaris 2.6's putc().

Problem noted by Ari Heikkinen of Pohjois-Savo 338364562Sgshapiro Polytechnic. 338464562Sgshapiro Under the proper circumstances, failed connections would be recorded 338564562Sgshapiro as "Bad file number" instead of "Connection failed" in the 338664562Sgshapiro queue file and persistent host status. Problem noted by 338764562Sgshapiro Graeme Hewson of Oracle. 338864562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 338964562Sgshapiro within the hoststatus directory (e.g., lost+found). 339064562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 339164562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 339264562Sgshapiro sender.

Problem noted by Michal Zalewski of the 366564562Sgshapiro "Internet for Schools" project (IdS). 366664562Sgshapiro SECURITY: There is a potential for a denial of service attack if 366764562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 366864562Sgshapiro sendmail process while it is rebuilding the aliases file 366964562Sgshapiro (leaving it in an inconsistent state). This option and 367064562Sgshapiro its use is deprecated and will be removed from a future 367164562Sgshapiro version of sendmail. 367264562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 367364562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 367464562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 367564562Sgshapiro (IdS). 367664562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 367764562Sgshapiro a large number of files. See cf/README for more details. 367864562Sgshapiro The directory structure of the distribution has changed slightly 367964562Sgshapiro for easier code sharing among the programs. 368064562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 368164562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 368264562Sgshapiro which hold the client's authentication credentials, 368364562Sgshapiro the mechanism used for authentication, and the 368464562Sgshapiro authorization identity (i.e., the AUTH= parameter if 368564562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 368664562Sgshapiro On systems which use the Torek stdio library (all of the BSD 368764562Sgshapiro distributions), use memory-buffered files to reduce 368864562Sgshapiro file system overhead by not creating temporary files on 368964562Sgshapiro disk. Contributed by Exactis.com, Inc. 369064562Sgshapiro New option DataFileBufferSize to control the maximum size of a 369164562Sgshapiro memory-buffered data (df) file before a disk-based file is 369264562Sgshapiro used. Contributed by Exactis.com, Inc. 369364562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 369464562Sgshapiro memory-buffered transcript (xf) file before a disk-based 369564562Sgshapiro file is used. Contributed by Exactis.com, Inc. 369664562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 369764562Sgshapiro now listen on several different ports. Use: 369864562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 369964562Sgshapiro to run a Message Submission Agent (MSA); this is turned 370064562Sgshapiro on by default in m4-generated .cf files; it can be turned 370164562Sgshapiro off with FEATURE(`no_default_msa'). 370264562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 370364562Sgshapiro begin using RFC 2476 Message Submission for initial user 370464562Sgshapiro message submission. XUSR may disappear from a future release. 370564562Sgshapiro The new '-G' (relay (gateway) submission) command line option 370664562Sgshapiro indicates that the message being submitted from the command 370764562Sgshapiro line is for relaying, not initial submission. This means 370864562Sgshapiro the message will be rejected if the addresses are not fully 370964562Sgshapiro qualified and no canonicalization will be done. Future 371064562Sgshapiro releases may even reject improperly formed messages. 371164562Sgshapiro The '-U' (initial user submission) command line option is 371264562Sgshapiro deprecated and may be removed from a future release. 371364562Sgshapiro Mail user agents should begin using '-G' to indicate that 371464562Sgshapiro this is a relay submission (the inverse of -U). 371564562Sgshapiro The next release of sendmail will assume that any message submitted 371664562Sgshapiro from the command line is an initial user submission and act 371764562Sgshapiro accordingly. 371864562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 371964562Sgshapiro program or deliver to file as the owner of that file, the 372064562Sgshapiro address is marked as unsafe. This means if RunAsUser is 372164562Sgshapiro set, users won't be able to use programs or delivery to 372264562Sgshapiro files in their .forward files. Administrators can override 372364562Sgshapiro this by setting the DontBlameSendmail option to the new 372464562Sgshapiro setting NonRootSafeAddr. 372564562Sgshapiro Allow group or world writable directories if the sticky bit is set 372664562Sgshapiro on the directory and DontBlameSendmail is set to 372764562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 372864562Sgshapiro InCert Software. 372964562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 373064562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 373164562Sgshapiro set in the DontBlameSendmail option. Requested by many. 373264562Sgshapiro New Timeout.control option to limit the total time spent satisfying 373364562Sgshapiro a control socket request. 373464562Sgshapiro New Timeout.resolver options for controlling BIND resolver 373564562Sgshapiro settings: 373664562Sgshapiro Timeout.resolver.retrans 373764562Sgshapiro Sets the resolver's retransmission time interval (in 373864562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 373964562Sgshapiro and Timeout.resolver.retrans.normal. 374064562Sgshapiro Timeout.resolver.retrans.first 374164562Sgshapiro Sets the resolver's retransmission time interval (in 374264562Sgshapiro seconds) for the first attempt to deliver a message. 374364562Sgshapiro Timeout.resolver.retrans.normal 374464562Sgshapiro Sets the resolver's retransmission time interval (in 374564562Sgshapiro seconds) for all resolver lookups except the first 374664562Sgshapiro delivery attempt. 374764562Sgshapiro Timeout.resolver.retry 374864562Sgshapiro Sets the number of times to retransmit a resolver 374964562Sgshapiro query. Sets both Timeout.resolver.retry.first 375064562Sgshapiro and Timeout.resolver.retry.normal. 375164562Sgshapiro Timeout.resolver.retry.first 375264562Sgshapiro Sets the number of times to retransmit a resolver 375364562Sgshapiro query for the first attempt to deliver a message. 375464562Sgshapiro Timeout.resolver.retry.normal 375564562Sgshapiro Sets the number of times to retransmit a resolver 375664562Sgshapiro query for all resolver lookups except the first 375764562Sgshapiro delivery attempt. 375864562Sgshapiro Contributed by Exactis.com, Inc. 375964562Sgshapiro Support multiple queue directories. To use multiple queues, supply 376064562Sgshapiro a QueueDirectory option value ending with an asterisk. For 376164562Sgshapiro example, /var/spool/mqueue/q* will use all of the 376264562Sgshapiro directories or symbolic links to directories beginning with 376364562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 376464562Sgshapiro mind, the queue directory structure should not be changed 376564562Sgshapiro while sendmail is running. Queue runs create a separate 376664562Sgshapiro process for running each queue unless the verbose flag is 376764562Sgshapiro given on a non-daemon queue run. New items are randomly 376864562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 376964562Sgshapiro Support different directories for qf, df, and xf queue files; if 377064562Sgshapiro subdirectories or symbolic links to directories of those names 377164562Sgshapiro exist in the queue directories, they are used for the 377264562Sgshapiro corresponding queue files. Keep in mind, the queue 377364562Sgshapiro directory structure should not be changed while sendmail is 377464562Sgshapiro running. Proposed by Mathias Koerber of Singapore 377564562Sgshapiro Telecommunications Ltd. 377664562Sgshapiro New queue file naming system which uses a filename guaranteed to be 377764562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 377864562Sgshapiro without fancy file system locking. Queued items can be 377964562Sgshapiro moved between queues easily. Contributed by Exactis.com, 378064562Sgshapiro Inc. 378164562Sgshapiro Messages which are undeliverable due to temporary address failures 378264562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 378364562Sgshapiro set. Contributed by Exactis.com, Inc. 378464562Sgshapiro New command line option '-L tag' which sets the identifier used for 378564562Sgshapiro syslog. Contributed by Exactis.com, Inc. 378664562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 378764562Sgshapiro avoids opening and reading each queue file when preparing 378864562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 378964562Sgshapiro Shared memory counters and microtimers functionality has been 379064562Sgshapiro donated by Exactis.com, Inc. 379164562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 379264562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 379364562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 379464562Sgshapiro being added. Suggested by Michael K. Sanders. 379564562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 379664562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 379764562Sgshapiro and John Beck of Sun Microsystems. 379864562Sgshapiro In low-disk space situations, where sendmail would previously refuse 379964562Sgshapiro connections, still accept them, but only allow ETRN commands. 380064562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 380164562Sgshapiro Ltd. 380264562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 380364562Sgshapiro on systems which support them. This can be used with LMTP 380464562Sgshapiro local delivery agents which listen on a named socket. An 380564562Sgshapiro example mailer might be: 380664562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 380764562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 380864562Sgshapiro A=FILE /var/run/lmtpd 380964562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 381064562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 381164562Sgshapiro instead. 381264562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 381364562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 381464562Sgshapiro connections), IPC (which will be deprecated in a future 381564562Sgshapiro version), and FILE (for UNIX domain socket delivery). 381664562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 381764562Sgshapiro flags. 381864562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 381964562Sgshapiro body of the original message on delivery status 382064562Sgshapiro notifications. 382164562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 382264562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 382364562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 382464562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 382564562Sgshapiro Steve Schweinhart of America Online. 382664562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 382764562Sgshapiro not be set after rulesets are defined. Suggested by 382864562Sgshapiro Mitchell Blank Jr of Exec-PC. 382964562Sgshapiro Do not report temporary failure on delivery to files. In 383064562Sgshapiro interactive delivery mode, this would result in two SMTP 383164562Sgshapiro responses after the DATA command.

Hillegas of Princeton University. 383764562Sgshapiro Always bind to the LDAP server regardless of whether you are using 383864562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 383964562Sgshapiro @Home Network. 384064562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 384164562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 384264562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 384364562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 384464562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 384564562Sgshapiro similar to check_rcpt etc. 384664562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 384764562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 384864562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 384964562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 385064562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 385164562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 385264562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 385364562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 385464562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 385564562Sgshapiro the corresponding DSN parameter values. Proposed by 385664562Sgshapiro Mathias Herberts. 385764562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 385864562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 385964562Sgshapiro before the message has been collected, thereafter it holds 386064562Sgshapiro the message size as computed by sendmail (and can be used 386164562Sgshapiro in check_compat). 386264562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 386364562Sgshapiro sendmail is using instead of the value of the DeliveryMode 386464562Sgshapiro option. 386564562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 386664562Sgshapiro Drop explicit From: if same as what would be generated only if it is 386764562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 386864562Sgshapiro Write pid to file also if sendmail only processes the queue. 386964562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 387064562Sgshapiro Log "low on disk space" only when necessary. 387164562Sgshapiro New macro ${load_avg} can be used to check the current load average. 387264562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 387364562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 387464562Sgshapiro is set. 387564562Sgshapiro Flag -S for maps to specify the character which is substituted 387664562Sgshapiro for spaces (instead of the default given by O BlankSub). 387764562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 387864562Sgshapiro This flag is set by default for the host map. Based on a 387964562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 388064562Sgshapiro Open maps only on demand, not at startup. 388164562Sgshapiro Log warning about unsupported IP address families. 388264562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 388364562Sgshapiro of the sum of all headers. This can be used to prevent 388464562Sgshapiro a denial-of-service attack. 388564562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 388664562Sgshapiro headers and parameters within those headers. This option 388764562Sgshapiro is intended to protect mail user agents from buffer 388864562Sgshapiro overflow attacks. 388964562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 389064562Sgshapiro alias recursion. 389164562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 389264562Sgshapiro Map type syslog to log the key via syslogd. 389364562Sgshapiro Entries in the alias file can be continued by putting a backslash 389464562Sgshapiro directly before the newline. 389564562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 389664562Sgshapiro dead.letter file, formerly hardcoded to 389764562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 389864562Sgshapiro default), sendmail will not attempt to save to a 389964562Sgshapiro system-wide dead.letter file if it can not bounce the mail 390064562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 390164562Sgshapiro file as it has in the past when the dead.letter file 390264562Sgshapiro could not be opened. 390364562Sgshapiro New option PidFile to define the location of the pid file. The 390464562Sgshapiro value of this option is macro expanded. 390564562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 390664562Sgshapiro process title shown in 'ps' listings. 390764562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 390864562Sgshapiro (along with the already existing macros): 390964562Sgshapiro ${daemon_info} Daemon information, e.g. 391064562Sgshapiro SMTP+queueing@00:30:00 391164562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 391264562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 391364562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 391464562Sgshapiro ${daemon_port} Daemon port, e.g., 25 391564562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 391664562Sgshapiro New macros especially for virtual hosting: 391764562Sgshapiro ${if_name} hostname of interface of incoming connection. 391864562Sgshapiro ${if_addr} address of interface of incoming connection. 391964562Sgshapiro The latter is only set if the interface does not belong to the 392064562Sgshapiro loopback net. 392164562Sgshapiro If a message being accepted via a method other than SMTP and 392264562Sgshapiro would be rejected by a header check, do not send the message. 392364562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 392464562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 392564562Sgshapiro Provide header value as quoted string in the macro 392664562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 392764562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 392864562Sgshapiro The length of the header value is stored in ${hdrlen}. 392964562Sgshapiro H*: allows to specify a default ruleset for header checks. This 393064562Sgshapiro ruleset will only be called if the individual header does 393164562Sgshapiro not have its own ruleset assigned. Suggested by Jan 393264562Sgshapiro Krueger of Unix-AG of University of Hannover. 393364562Sgshapiro The name of the header field stored in ${hdr_name}. 393464562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 393564562Sgshapiro removed if the config file version is greater than or equal 393664562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 393764562Sgshapiro input "token (1)" but does not match "token". 393864562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 393964562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 394064562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 394164562Sgshapiro Ericsson. 394264562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 394364562Sgshapiro messages with 8-bit text in headers. Problem noted by 394464562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 394564562Sgshapiro of Ericsson. 394664562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 394764562Sgshapiro modified database map file. Problem noted by Chris Adams 394864562Sgshapiro of Renaissance Internet Services. 394964562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 395064562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 395164562Sgshapiro queue up the message instead of bouncing it. 395264562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 395364562Sgshapiro standard does not provide any indication of what to do when 395464562Sgshapiro something other than 250 is received. Based on a patch 395564562Sgshapiro from Steve Schweinhart of America Online. 395664562Sgshapiro New option TrustedUser allows to specify a user who can own 395764562Sgshapiro important files instead of root. This requires HASFCHOWN. 395864562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 395964562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 396064562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 396164562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 396264562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 396364562Sgshapiro $? tests also whether the macro is non-null. 396464562Sgshapiro Print an error message if a mailer definition contains an invalid 396564562Sgshapiro equate name. 396664562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 396764562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 396864562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 396964562Sgshapiro mailer to return after sending all data to it. 397064562Sgshapiro Only free memory from the process list when adding a new process 397164562Sgshapiro into a previously filled slot. Previously, the memory was 397264562Sgshapiro freed at removal time. Since removal can happen in a 397364562Sgshapiro signal handler, this may leave the memory map in an 397464562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 397564562Sgshapiro David Cooley of Colby College. 397664562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 397764562Sgshapiro local users in the passwd file. The UserDB code has 397864562Sgshapiro already decided the message will be passed to another host 397964562Sgshapiro for processing. Fix from Tony Landells of Burdett 398064562Sgshapiro Buckeridge Young Limited. 398164562Sgshapiro Support LDAP authorization via either a file containing the 398264562Sgshapiro password or Kerberos V4 using the new map options 398364562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 398464562Sgshapiro distinguished_name is who to login as. The method can be 398564562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 398664562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 398764562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 398864562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 398964562Sgshapiro of Stanford University. 399064562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 399164562Sgshapiro deprecated and will be removed in a future version. 399264562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 399364562Sgshapiro and the map has the column delimiter set, it turns that 399464562Sgshapiro response into a delimiter separated string. The LDAP map 399564562Sgshapiro will traverse multiple entries as well. LDAP alias maps 399664562Sgshapiro automatically set the column delimiter to the comma. 399764562Sgshapiro Based on patch from Booker Bense of Stanford University and 399864562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 399964562Sgshapiro Support return of multiple values for a single LDAP lookup. The 400064562Sgshapiro values to be returned should be in a comma separated string. 400164562Sgshapiro For example, `-v "email,emailother"'. Patch from 400264562Sgshapiro Curtis W. Hillegas of Princeton University. 400364562Sgshapiro Allow the use of LDAP for alias maps. 400464562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 400564562Sgshapiro attributes found in the match will be returned. 400664562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 400764562Sgshapiro breaking up a single entry into multiple entries. This is 400864562Sgshapiro needed for LDAP alias file specifications to allow for 400964562Sgshapiro comma separated key and value strings. 401064562Sgshapiro Keep connections to LDAP server open instead of opening and closing 401164562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 401264562Sgshapiro connections such that multiple maps which use the same 401364562Sgshapiro host, port, bind DN, and authentication will only result in 401464562Sgshapiro a single connection to that host. 401564562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 401664562Sgshapiro Be more careful about checking for errors and freeing memory on 401764562Sgshapiro LDAP lookups. 401864562Sgshapiro Use asynchronous LDAP searches to save memory and network 401964562Sgshapiro resources. 402064562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 402164562Sgshapiro Increase portability to the Netscape LDAP libraries. 402264562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 402364562Sgshapiro replaced with the literal contents of the map lookup key -- 402464562Sgshapiro note that this means a lookup can be done using the LDAP 402564562Sgshapiro special characters. The new '%0' token can be used instead 402664562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 402764562Sgshapiro For example, if the LDAP map specification contains '-k 402864562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 402964562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 403064562Sgshapiro user attribute. Instead, if the LDAP map specification 403164562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 403264562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 403364562Sgshapiro with the name "*". 403464562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 403564562Sgshapiro more than one is returned, it is equivalent to no records 403664562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 403764562Sgshapiro alias dereference option; "-Z size" limits the number of 403864562Sgshapiro matches to return. 403964562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 404064562Sgshapiro LDAP maps. The value should only contain LDAP specific 404164562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 404264562Sgshapiro settings will be used for all LDAP maps unless they are 404364562Sgshapiro specified in the individual map specification ('K' 404464562Sgshapiro command). This option should be set before any LDAP maps 404564562Sgshapiro are defined. 404664562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 404764562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 404864562Sgshapiro Tech. 404964562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 405064562Sgshapiro particular, class entries get much smaller, which can be 405164562Sgshapiro important if you have large classes. 405264562Sgshapiro On network-related temporary failures, record the hostname which 405364562Sgshapiro gave error in the queued status message. Requested by 405464562Sgshapiro Ulrich Windl of the Universitat Regensburg. 405564562Sgshapiro Add new F=% mailer flag to allow for a store and forward 405664562Sgshapiro configuration. Mailers which have this flag will not attempt 405771345Sgshapiro delivery on initial receipt of a message or on queue runs 405864562Sgshapiro unless the queued message is selected using one of the 405964562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 406064562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 406164562Sgshapiro New option ControlSocketName which, when set, creates a daemon 406264562Sgshapiro control socket. This socket allows an external program to 406364562Sgshapiro control and query status from the running sendmail daemon 406464562Sgshapiro via a named socket, similar to the ctlinnd interface to the 406564562Sgshapiro INN news server. Access to this interface is controlled by 406664562Sgshapiro the UNIX file permissions on the named socket on most UNIX 406764562Sgshapiro systems (see sendmail/README for more information). An 406864562Sgshapiro example control program is provided as contrib/smcontrol.pl. 406964562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 407064562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 407164562Sgshapiro number of processors online on the system (if that can be 407264562Sgshapiro determined). For single processor machines, this change 407364562Sgshapiro has no effect. 407464562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 407564562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 407664562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 407764562Sgshapiro Motonori Nakamura of Kyoto University. 407864562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 407964562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 408064562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 408164562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 408264562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 408364562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 408464562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 408564562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 408664562Sgshapiro connection-based denial of service attacks. 408764562Sgshapiro Log basic information about authenticated connections at LogLevel 408864562Sgshapiro 10 or higher. 408964562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 409064562Sgshapiro information (from= syslog line). 409164562Sgshapiro Log the DSN code for each recipient if one is available as a new 409264562Sgshapiro equate (dsn=). 409364562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 4094120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 4095120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 4096120256Sgshapiro of the University of Illinois at Urbana-Champaign. 409764562Sgshapiro Detect temporary lookup failures in the host map if looking up a 409864562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 409964562Sgshapiro Finnish Meteorological Institute. 410064562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 410164562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 410264562Sgshapiro When a forward file points to an alias which runs a program, run 410364562Sgshapiro the program as the default user and the default group, not 410464562Sgshapiro the forward file user. This change also assures the 410564562Sgshapiro :include: directives in aliases are also processed using 410664562Sgshapiro the default user and group. Problem noted by Sergiu 410764562Sgshapiro Popovici of DNT Romania. 410864562Sgshapiro Prevent attempts to save a dead.letter file for a user with 410964562Sgshapiro no home directory (/no/such/directory). Problem noted by 411064562Sgshapiro Michael Brown of Finnigan FT/MS. 411164562Sgshapiro Include message delay and number of tries when logging that a 411264562Sgshapiro message has been completely delivered (LogLevel of 10 or 411364562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 411464562Sgshapiro Log the sender of a message even if none of the recipients were 411564562Sgshapiro accepted. If some of the recipients were rejected, it is 411664562Sgshapiro helpful to know the sender of the message. 411764562Sgshapiro Check the root directory (/) when checking a path for safety. 411864562Sgshapiro Problem noted by John Beck of Sun Microsystems. 411964562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 412064562Sgshapiro interactive and delivering to an alias which resolves to 412164562Sgshapiro multiple files. 412264562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 412364562Sgshapiro greater (see below); the help function doesn't print the 412464562Sgshapiro version of sendmail any longer, instead it is placed in 412564562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 412664562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 412764562Sgshapiro skipped and a version line (#vers) is introduced. The 412864562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 412964562Sgshapiro version is found, a warning is logged. The '#vers' 413064562Sgshapiro directive should be placed at the top of the help file. 413164562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 413264562Sgshapiro disk succeeded. Suggested by Nick Christenson. 413364562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 413464562Sgshapiro length before the attempt. 413564562Sgshapiro If a forward points to a filename for delivery, change to the 413664562Sgshapiro user's uid before checking permissions on the file. This 413764562Sgshapiro allows delivery to files on NFS mounted directories where 413864562Sgshapiro root is remapped to nobody. Problem noted by Harald 413964562Sgshapiro Daeubler of Universitaet Ulm. 414064562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 414164562Sgshapiro host status files, not all files. 414264562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 414364562Sgshapiro in the queue file for the message and set when delivery 414464562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 414564562Sgshapiro Wonderworks Inc. 414664562Sgshapiro Add support for storing information between rulesets using the new 414764562Sgshapiro macro map class. This can be used to store information 414864562Sgshapiro between queue runs as well using $={persistentMacros}. 414964562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 415064562Sgshapiro of Hannover. 415164562Sgshapiro New map class arith to allow for computations in rules. The 415264562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 415364562Sgshapiro as key. The two operands are specified as arguments; the 415464562Sgshapiro lookup returns the result of the computation. For example, 415564562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 415664562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 415764562Sgshapiro Add new syntax for header declarations which decide whether to 415864562Sgshapiro include the header based on a macro rather than a mailer 415964562Sgshapiro flag: 416064562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 416164562Sgshapiro This should be used along with $={persistentMacros}. 416264562Sgshapiro It can be used for adding headers to a message based on 416364562Sgshapiro the results of check_* and header check rulesets. 416464562Sgshapiro Allow new named config file rule check_eoh which is called after 416564562Sgshapiro all of the headers have been collected. The input to the 416664562Sgshapiro ruleset the number of headers and the size of all of the 416764562Sgshapiro headers in bytes separated by $|. This ruleset along with 416864562Sgshapiro the macro storage map can be used to correlate information 416964562Sgshapiro gathered between headers and to check for missing headers. 417064562Sgshapiro See cf/README or doc/op/op.ps for an example. 417164562Sgshapiro Change the default for the MeToo option to True to correspond 417264562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 417364562Sgshapiro option is deprecated and will be removed from a future 417464562Sgshapiro version. 417564562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 417664562Sgshapiro Change the sendmail binary default for SuperSafe to True. 417764562Sgshapiro Display ruleset names in debug and address test mode output 417864562Sgshapiro if referencing a named ruleset. 417964562Sgshapiro New mailer equate m= which will limit the number of messages 418064562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 418164562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 418264562Sgshapiro using it to sort. Now all the same domains are really run 418364562Sgshapiro through the queue together. If they have the same MX host, 418464562Sgshapiro then they will have a much better opportunity to use the 418564562Sgshapiro connection cache if available. This should be a reasonable 418664562Sgshapiro performance improvement. Patch from Randall Winchester of 418764562Sgshapiro the University of Maryland. 418864562Sgshapiro If a message is rejected by a header check ruleset, log who would 418964562Sgshapiro have received the message if it had not been rejected. 419064562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 419164562Sgshapiro queue immediately.

Problem noted by Per 436664562Sgshapiro Hedeland of Ericsson. 436764562Sgshapiro mailq displays unprintable characters in addresses as their octal 436864562Sgshapiro representation and a leading backslash. This avoids problems 436964562Sgshapiro with "unprintable" characters. Problem noted by Michal 437064562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 437164562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 437264562Sgshapiro one character past the limit. This would cause subsequent 437364562Sgshapiro hops to break the line again. The '!' is now placed in 437464562Sgshapiro the last column of the limit if the line needs to be broken. 437564562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 437664562Sgshapiro from Per Hedeland of Ericsson. 437764562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 437864562Sgshapiro resolver will fall back to TCP. However, some 437964562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 438064562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 438164562Sgshapiro don't fail on ANY queries. 438264562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 438364562Sgshapiro address, do not send an empty postmaster notification DSN 438464562Sgshapiro to the postmaster.

Prindeville of Enteka Enterprise Technology 460964562Sgshapiro Services. 461064562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 461164562Sgshapiro names. Problem noted by Randall Winchester of Swales 461264562Sgshapiro Aerospace. 461364562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 461464562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 461564562Sgshapiro University and Brian Candler. 461664562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 461764562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 461864562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 461964562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 462064562Sgshapiro Institute. 462164562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 462264562Sgshapiro i.e., to set, add, or delete flags. 462364562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 462464562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 462564562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 462664562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 462764562Sgshapiro after check_rcpt and allows for exceptions from the checks. 462864562Sgshapiro CONFIG: Map declarations have been moved into their associated 462964562Sgshapiro feature files to allow greater flexibility in use of 463064562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 463164562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 463264562Sgshapiro line string for the local mailer. Requested by Il Oh of 463364562Sgshapiro Willamette Industries, Inc. 463464562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 463564562Sgshapiro converted to <user@d> 463664562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 463764562Sgshapiro Sun's older, broken configuration files. 463864562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 463964562Sgshapiro normal configuration, allowing anti-spam checks to be 464064562Sgshapiro performed. 464164562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 464264562Sgshapiro ${client_name} can't be resolved just temporarily. 464364562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 464464562Sgshapiro Institute. 464564562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 464664562Sgshapiro be accessed by their numbers). 464764562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 464864562Sgshapiro which describes whether to disallow "!" in the local part 464964562Sgshapiro of an address. 465064562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 465164562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 465264562Sgshapiro set. If the ruleset returns a mailer, the appropriate 465364562Sgshapiro action is taken, otherwise the returned tokens are ignored. 465464562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 465564562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 465664562Sgshapiro The latter is kept around for backward compatibility. 465764562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 465864562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 465964562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 466064562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 466164562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 466264562Sgshapiro Institute. 466364562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 466464562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 466564562Sgshapiro arguments overriding the mailer program, arguments, and 466664562Sgshapiro mailer definition flags. This makes it possible to use 466764562Sgshapiro other programs such as maildrop for local delivery. 466864562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 466964562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 467064562Sgshapiro Patch from Richard A.

Problem noted by Ezequiel H. Panepucci of 468664562Sgshapiro Yale University. 468764562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 468864562Sgshapiro be used for building. 468964562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 469064562Sgshapiro used for a fresh build. 469164562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 469264562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 469364562Sgshapiro ranlib. 469464562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 469564562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 469664562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 469764562Sgshapiro building of the man pages when defined. Suggested by Bryan 469864562Sgshapiro Costales. 469964562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 470064562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 470164562Sgshapiro installation of the sendmail helpfile and statistics file 470264562Sgshapiro respectively. Suggested by Bryan Costales. 470364562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 470464562Sgshapiro of Siemens Business Services. 470564562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 470664562Sgshapiro stdio library. The new buffered file I/O depends on the 470764562Sgshapiro Torek stdio library. This option can be either portable or 470864562Sgshapiro torek. 470964562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 471064562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 471164562Sgshapiro They should contain the C source files for the object files 471264562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 471364562Sgshapiro will be passed to the 'make depend' stage of compilation. 471464562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 471564562Sgshapiro in the sendmail distribution. Each has the form 471664562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 471764562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 471864562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 471964562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 472064562Sgshapiro building the distribution, but documentation on the changes 472164562Sgshapiro are in devtools/README. 472264562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 472364562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 472464562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 472564562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 472664562Sgshapiro new variable which identifies the root of the source 472764562Sgshapiro directories for all of the programs in the distribution. 472864562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 472964562Sgshapiro time. They can both still be overridden by setting the m4 473064562Sgshapiro macro. 473164562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 473264562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 473364562Sgshapiro build configurations, and places objects in obj.prefix.*/. 473464562Sgshapiro Complains as 'Build -f file' does for existing object 473564562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 473664562Sgshapiro Corporation. 473764562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 473864562Sgshapiro manual pages in the directory tree specified by 473964562Sgshapiro confMANROOTMAN. 474064562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 474164562Sgshapiro preformatted pages from the distribution. The new variable 474264562Sgshapiro confCOPY specifies the copying program. 474364562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 474464562Sgshapiro question. Suggested by Terry Lambert of Whistle 474564562Sgshapiro Communications. 474664562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 474764562Sgshapiro of the installed statistics and help files, respectively. 474864562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 474964562Sgshapiro operating system identity. Problem noted by Erik 475064562Sgshapiro Wachtenheim of Dartmouth College. 475164562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 475264562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 475364562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 475464562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 475564562Sgshapiro how to strip binaries. These are used by the new 475664562Sgshapiro install-strip target. 475764562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 475864562Sgshapiro the others (if it exists). 475964562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 476064562Sgshapiro then the default ones. 476190792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 476264562Sgshapiro as local delivery agent without LMTP mode, use 476364562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 476464562Sgshapiro to set the S flag. 476564562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 476664562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 476764562Sgshapiro Northern Illinois University. 476864562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 476964562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 477064562Sgshapiro the Finnish Meteorological Institute. 477164562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 477264562Sgshapiro MAILLOCK when compiling. Also requires linking with 477364562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 477464562Sgshapiro University. 477564562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 477664562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 477764562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 477864562Sgshapiro University. 477964562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 478064562Sgshapiro structure to the beginning of the program. This ensures that 478164562Sgshapiro the getservbyname() is done before any seteuid to a possibly 478264562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 478364562Sgshapiro on a Solaris system, this avoids syslog messages such as, 478464562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 478564562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 478664562Sgshapiro University. 478764562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 478864562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 478964562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 479064562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 479164562Sgshapiro characters (in LMTP mode), mail.local split the incoming 479264562Sgshapiro line up into 2046-character output lines (excluding the 479364562Sgshapiro newline).

Sites 529138032Speter which need the ability to override security can use the 529238032Speter DontBlameSendmail option. See the README file for more 529338032Speter information. 529438032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 529538032Speter if maps or alias files are in world writable directories. 529638032Speter This fixes the change added to 8.8.6 to prevent links in these 529738032Speter world writable directories. 529838032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 529938032Speter it is in a world writable directory. 530038032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 530138032Speter tty it may be able to push bytes back to the senders input. 530238032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 531138032Speter reverts back to the old behavior of using uid 1 and gid 1. 531238032Speter This is a security problem for Linux which has chosen that 531338032Speter uid and gid for user bin instead of daemon. If DefaultUser 531438032Speter is set in the configuration file, that value overrides this 531538032Speter default. 531690792Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-ID binaries 531738032Speter interfered with setting an alternate group id for the 531838032Speter RunAsUser option.

After this number is reached, sendmail 536238032Speter starts returning "452 Too many recipients" to all RCPT 536338032Speter commands. This can be used to limit the number of recipients 536438032Speter per envelope (in particular, to discourage use of the server 536538032Speter for spamming). Note: a better approach is to restrict 536638032Speter relaying entirely. 536738032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 536838032Speter to ldapx map and added timeout for ldap_open call to 536938032Speter avoid hanging sendmail in the event of hung LDAP servers. 537038032Speter Patch from Booker Bense of Stanford University. 537138032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 539038032Speter of Procter & Gamble. 539138032Speter The LDAP map -s flag was not properly parsed and the error message 539264562Sgshapiro given included the remainder of the arguments instead of 539338032Speter solely the argument in error. Problem noted by Aidan Nichol 539438032Speter of Procter & Gamble. 539538032Speter New DontBlameSendmail option. This option allows administrators to 539638032Speter bypass some of sendmail's file security checks at the expense 539738032Speter of system security.

In particular, if you 543338032Speter have lots of virtual interfaces, this option will speed up 543438032Speter startup.

If they differ or if the PTR lookup 544438032Speter fails, &{client_name} will contain the IP address 544564562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 544638032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 544738032Speter (i.e, it is like -ax for the temporary failure case, in 544838032Speter contrast to the success case). 544938032Speter New syntax to do limited checking of header syntax. A config line 545038032Speter of the form: 545138032Speter HHeader: $>Ruleset 545238032Speter causes the indicated Ruleset to be invoked on the Header 545338032Speter when read. This ruleset works like the check_* rulesets -- 545438032Speter that is, it can reject mail on the basis of the contents. 545538032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 545638032Speter from hiding their connection information in Received: 545738032Speter headers. 545838032Speter When SingleThreadDelivery is active, deliveries to locked hosts 545938032Speter are skipped. This will cause the delivering process to 546038032Speter try the next MX host or queue the message if no other MX 546138032Speter hosts are available. Suggested by Alexander Litvin. 546238032Speter The [FILE] mailer type now delivers to the file specified in the 546338032Speter A= equate of the mailer definition instead of $u. It also 546438032Speter obeys all of the F= mailer flags such as the MIME 546538032Speter 7/8 bit conversion flags. This is useful for defining 546638032Speter a mailer which delivers to the same file regardless of the 546764562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 546838032Speter Do not assume the identity of a remote connection is root@localhost 546938032Speter if the remote connection closes the socket before the 547038032Speter remote identity can be queried. 547138032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 547238032Speter Some mailers, including procmail, require that the real 547338032Speter uid is left unchanged by sendmail. Problem noted by Per 547438032Speter Hedeland of Ericsson. 547538032Speter No longer is the src/obj*/Makefile selected from a large list -- it 547638032Speter is now generated using the information in BuildTools/OS/ -- 547738032Speter some of the details are determined dynamically via 547838032Speter BuildTools/bin/configure.sh. 547938032Speter The other programs in the sendmail distribution -- mail.local, 548038032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 548138032Speter the new Build method which creates an operating system 548238032Speter specific Makefile using the information in BuildTools. 548338032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 548438032Speter a failure on one message won't affect future messages to the 548538032Speter same host). This is necessary if the remote host sends 548638032Speter a 451 error if the domain of the sender does not resolve 548738032Speter as is common in anti-spam configurations. Problem noted 548838032Speter by Mitchell Blank Jr of Exec-PC. 548938032Speter New "discard" mailer for check_* rulesets and header checking 549038032Speter rulesets. If one of the above rulesets resolves to the 549138032Speter $#discard mailer, the commands will be accepted but the 549238032Speter message will be completely discarded after it is accepting. 549338032Speter This means that even if only one of the recipients 549438032Speter resolves to the $#discard mailer, none of the recipients 549538032Speter will receive the mail. Suggested by Brian Kantor. 549638032Speter All but the last cloned envelope of a split envelope were queued 549738032Speter instead of being delivered.

To obtain the 561238032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 561338032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 561438032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 561538032Speter the user to setup different .forward files for 561638032Speter user+detail addressing. 561738032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 561838032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 561938032Speter DontProbeInterfaces, and DontBlameSendmail options. 562038032Speter CONFIG: by default do not allow relaying (that is, accepting mail 562138032Speter from outside your domain and sending it to another host 562238032Speter outside your domain). 562338032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 562438032Speter any site to any site. 562538032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 562638032Speter domain as defined by the 'm' class ($=m) to relay. 562738032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 562838032Speter the MX records of the host portion of an incoming recipient. 562938032Speter CONFIG: new FEATURE(access_db) which turns on the access database 563077349Sgshapiro feature. This database gives you the ability to allow 563138032Speter or refuse to accept mail from specified domains for 563238032Speter administrative reasons. By default, names that are listed 563338032Speter as "OK" in the access db are domain names, not host names. 563438032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 563538032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 563638032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 563738032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 563838032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 563938032Speter of FEATURE(access_db) and class 'R' to lookup individual 564038032Speter host names only. 564138032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 564238032Speter using % addressing is used, e.g. user%site@othersite, 564338032Speter and othersite is in class 'R', the check_rcpt ruleset 564438032Speter will strip @othersite and recheck user@site for relaying. 564538032Speter This feature changes that behavior. It should not be 564638032Speter needed for most installations. 564738032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 564838032Speter domain portion of the mail sender is a local host. This 564938032Speter should only be used if absolutely necessary as it opens 565038032Speter a window for spammers. Patch from Randall S. Winchester of 565138032Speter the University of Maryland. 565238032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 565338032Speter block incoming mail destined for certain recipient 565438032Speter usernames, hostnames, or addresses. 565538032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 565638032Speter refused if the host part of the argument to MAIL FROM: cannot 565738032Speter be located in the host name service (e.g., DNS). 565838032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 565938032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 566038032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 566138032Speter MAIL FROM: senders which do not include a domain. 566238032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 566338032Speter Realtime Blackhole List. You can specify the RBL name 566438032Speter server to contact by specifying it as an optional argument. 566538032Speter The default is rbl.maps.vix.com.

Problem noted by Kari Hurtta of the Finnish 581138032Speter Meteorological Institute. 581238032Speter If /usr/tmp/dead.letter already existed, sendmail could not 581338032Speter add additional bounces to it. Problem noted by Thomas J. 581438032Speter Arseneault of SRI International. 581538032Speter If an SMTP mailer used a non-standard port number for the outgoing 581638032Speter connection, it would be displayed incorrectly in verbose mode. 581738032Speter Problem noted by John Kennedy of Cal State University, Chico. 581838032Speter Log the ETRN parameter specified by the client before altering them 581938032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 582038032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 582138032Speter User unknown with bogus delay= values. Change them to log 582238032Speter the same as compliant addresses. Problem noted by Kari E. 582338032Speter Hurtta of the Finnish Meteorological Institute. 582438032Speter Ignore the debug resolver option unless using sendmail debug trace 582538032Speter option for resolver. Problem noted by Greg Nichols of Wind 582638032Speter River Systems. 582738032Speter If SingleThreadDelivery was enabled and the remote server returned a 582838032Speter protocol error on the DATA command, the connection would be 582938032Speter closed but the persistent host status file would not be 583038032Speter unlocked so other sendmail processes could not deliver to 583138032Speter that host. Problem noted by Peter Wemm of DIALix. 583238032Speter If queueing up a message due to an expensive mailer, don't increment 583338032Speter the number of delivery attempts or set the last delivery 583438032Speter attempt time so the message will be delivered on the next 583538032Speter queue run regardless of MinQueueAge. Problem noted by 583638032Speter Brian J. Coan of the Institute for Global Communications. 583738032Speter Authentication warnings of "Processed from queue _directory_" and 583838032Speter "Processed by _username_ with -C _filename_" would be logged 583938032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 584038032Speter of the Finnish Meteorological Institute. 584138032Speter Use a better heuristic for detecting GDBM. 584238032Speter Log null connections on dropped connections. Problem noted by 584338032Speter Jon Lewis of Florida Digital Turnpike. 584438032Speter If class dbm maps are rebuilt, sendmail will now detect this and 584538032Speter reopen the map. Previously, they could give stale 584638032Speter results during a single message processing (but would 584738032Speter recover when the next message was received). Fix from 584838032Speter Joe Pruett of Q7 Enterprises. 584938032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 585038032Speter requests. Problem noted by Kari E. Hurtta of the 585138032Speter Finnish Meteorological Institute. 585238032Speter Do not send a bounce message back to the sender regarding bad 585338032Speter recipients if the SMTP connection is dropped before the 585438032Speter message is accepted. Problem noted by Kari E. Hurtta of the 585538032Speter Finnish Meteorological Institute. 585638032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 585738032Speter sendmail via a UNIX pipe. This will allow rulesets using 585838032Speter $&{client_name} to process without sending the string through 585938032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 586038032Speter A combination of deferred delivery mode, a double bounce situation, 586138032Speter and the inability to save a bounce message to 586238032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 586338032Speter to postmaster but not remove the offending envelope from the 586438032Speter queue causing it to create a new bounce message each time the 586538032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 586638032Speter Associates. 586738032Speter Remove newlines from hostname information returned via DNS. There are 586838032Speter no known security implications of newlines in hostnames as 586938032Speter sendmail filters newlines in all vital areas; however, this 587038032Speter could cause confusing error messages. 587138032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 587238032Speter rejected if any of the specified addresses were bad. This 587338032Speter behavior was modified to only reject the bad addresses and not 587438032Speter the entire message. Problem noted by Jozsef Hollosi of 587538032Speter SuperNet, Inc. 587638032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 587738032Speter Bryan Costales of InfoBeat, Inc. 587838032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 587938032Speter mailers. Problem noted by Kari E. Hurtta of the 588038032Speter Finnish Meteorological Institute. 588138032Speter An error in calculating the available space in the list of addresses 588238032Speter for logging deliveries could cause an address to be silently 588338032Speter dropped. 588438032Speter Include the initial user environment if sendmail is restarted via 588538032Speter a HUP signal. This will give room for the process title. 588638032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 588738032Speter Mail could be delivered without a body if the machine does not 588838032Speter support flock locking and runs out of processes during 588938032Speter delivery. Fix from Chuck Lever of the University of Michigan. 589038032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 589138032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 589238032Speter Institute. 589338032Speter Make sure non-rebuildable database maps are opened before the 589464562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 589538032Speter are needed for verifying the left hand side of the aliases. 589638032Speter Problem noted by Lloyd Parkes of Victoria University. 589738032Speter Make sure sender RFC822 source route addresses are alias expanded for 589838032Speter bounce messages. Problem noted by Juergen Georgi of 589938032Speter RUS University of Stuttgart. 590038032Speter Minor lint fixes. 590138032Speter Return a temporary error instead of a permanent error if an LDAP map 590238032Speter search returns an error. This will allow sequenced maps which 590338032Speter use other LDAP servers to be checked. Fix from Booker Bense 590438032Speter of Stanford University. 590538032Speter When automatically converting from quoted printable to 8bit text do 590638032Speter not pad bare linefeeds with a space. Problem noted by Theo 590738032Speter Nolte of the University of Technology Aachen, Germany. 590838032Speter Portability: 590938032Speter Non-standard C compilers may have had a problem compiling 591038032Speter conf.c due to a standard C external declaration of 591138032Speter setproctitle(). Problem noted by Ted Roberts of 591238032Speter Electronic Data Systems. 591338032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 591438032Speter Jagielski of jaguNET Access Services. 591538032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 591638032Speter Digital UNIX: Digital UNIX (and possibly others) moves 591738032Speter loader environment variables into the loader memory 591838032Speter area. If one of these environment variables (such as 591938032Speter LD_LIBRARY_PATH) was the last environment variable, 592038032Speter an invalid memory address would be used by the process 592138032Speter title routine causing memory corruption. Problem 592238032Speter noted by Sam Hartman of Mesa Internet Systems. 592338032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 592438032Speter chownsafe() to always return 0 even if the OS does 592538032Speter not permit file giveaways. Problem noted by 592638032Speter Yasutaka Sumi of The University of Tokyo. 592764562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 592838032Speter Gerald Rinske of Siemens Business Services VAS. 592938032Speter Linux: Pad process title with NULLs. Problem noted by 593038032Speter Jon Lewis of Florida Digital Turnpike. 593138032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 593238032Speter incorrect value for the number of interfaces. 593338032Speter Problem noted by Chris Loelke of JetStream Internet 593438032Speter Services. 593538032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 593638032Speter Rinske of Siemens Business Services VAS. 593738032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 593838032Speter used on a Solaris machine. Problem noted by 593938032Speter Stephen Ma of Jtec Pty Limited. 594038032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 594138032Speter Services VAS. 594238032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 594338032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 594438032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 594538032Speter Ericsson. 594638032Speter 594764562Sgshapiro8.8.7/8.8.7 1997/08/03 594838032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 594938032Speter an exclusive lock already set -- i.e., almost all systems 595038032Speter except 4.4-BSD derived systems), the initial attempt at 595138032Speter rebuilding aliases file if the database didn't already 595238032Speter exist would fail. Patch from Raymund Will of LST Software 595338032Speter GmbH. 595438032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 595538032Speter Problem noted by Fredrik J�nsson of the Royal Institute 595638032Speter of Technology, Stockholm. 595738032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 595838032Speter some environments could give "multiple definitions" for these 595938032Speter routines during compilation. If using TCP Wrappers, assume 596038032Speter that these routines are included as though they were in the 596138032Speter C library. Patch from Robert La Ferla. 596238032Speter When a NEWDB database map was rebuilt at the same time it was being 596338032Speter used by a queue run, the maps could be left locked for the 596438032Speter duration of the queue run, causing other processes to hang. 596538032Speter Problem noted by Kendall Libby of Shore.NET. 596638032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 596738032Speter mail was passed on without any recipient header. This could 596838032Speter cause problems downstream. Problem noted by Xander Jansen 596938032Speter of SURFnet ExpertiseCentrum. 597038032Speter Give error when GDBM is used with sendmail. GDBM's locking and 597138032Speter linking of the .dir and .pag files interferes with sendmail's 597238032Speter locking and security checks. Problems noted by Fyodor 597338032Speter Yarochkin of the Kyrgyz Republic FreeNet. 597438032Speter Don't fsync qf files if SuperSafe option is not set. 597538032Speter Avoid extra calls to gethostbyname for addresses for which a 597638032Speter gethostbyaddr found no value. Also, ignore any returns 597738032Speter from gethostbyaddr that look like a dotted quad. 597838032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 597938032Speter "may be forged", since at the network level we pretty much 598038032Speter have to assume that the information is good. 598138032Speter In some cases, errors during an SMTP session could leave files 598238032Speter open or locked. 598338032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 598490792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 598538032Speter errors during testing. 598638032Speter Errors in file locking of NEWDB maps had the incorrect file name 598738032Speter printed in the error message. 598838032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 598938032Speter missing parameter were issued, the EHLO behaved like a HELO. 599038032Speter Load limiting never kicked in for incoming SMTP transactions if the 599143730Speter DeliveryMode=background and any recipient was an alias or 599238032Speter had a .forward file. From Nik Conwell of Boston University. 599338032Speter On some non-Posix systems, the decision of whether chown(2) permits 599438032Speter file giveaway was undefined. From Tetsu Ushijima of the 599538032Speter Tokyo Institute of Technology. 599638032Speter Fix race condition that could cause the body of a message to be 599738032Speter lost (so only the header was delivered). This only occurs 599838032Speter on systems that do not use flock(2), and only when a queue 599938032Speter runner runs during a critical section in another message 600038032Speter delivery. Based on a patch from Steve Schweinhart of 600138032Speter Results Computing. 600238032Speter If a qf file was found in a mail queue directory that had a problem 600338032Speter (wrong ownership, bad format, etc.) and the file name was 600438032Speter exactly MAXQFNAME bytes long, then instead of being tried 600538032Speter once, it would be tried on every queue run. Problem noted 600638032Speter by Bryan Costales of Mercury Mail. 600738032Speter If the system supports an st_gen field in the status structure, 600838032Speter include it when reporting that a file has changed after open. 600938032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 601038032Speter This out to be checked as well as reported, since it is 601138032Speter theoretically possible for an attacker to remove a file after 601238032Speter it is opened and replace it with another file that has the 601338032Speter same i-number, but some filesystems (notably AFS) return 601438032Speter garbage in this field, and hence always look like the file 601538032Speter has changed. As a practical matter this is not a security 601638032Speter problem, since the files can be neither hard nor soft links, 601738032Speter and on no filesystem (that I am aware of) is it possible to 601838032Speter have two files on the same filesystem with the same i-number 601938032Speter simultaneously. 602038032Speter Delete the root Makefile from the distribution -- it is only for 602138032Speter use internally, and does not work at customer sites. 602238032Speter Fix botch that caused the second MAIL FROM: command in a single 602338032Speter transaction to clear the entire transaction. Problem 602438032Speter noted by John Kennedy of Cal State University, Chico. 602538032Speter Work properly on machines that have _PATH_VARTMP defined without 602638032Speter a trailing slash. (And a pox on vendors that decide to 602738032Speter ignore the established conventions!) Problem noted by 602838032Speter Gregory Neil Shapiro of WPI. 602938032Speter Internal changes to make it easier to add another protocol family 603038032Speter (intended for IPv6). Patches are from John Kennedy of 603138032Speter CSU Chico. 603238032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 603338032Speter an extra space at the beginning of some lines. Problem 603438032Speter noted by Charles Karney of Princeton University; fix based 603538032Speter on a patch from Christophe Wolfhugel. 603638032Speter Portability: 603738032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 603838032Speter with the _Sendmail_ book, 2nd edition. Note that 603938032Speter the book is actually wrong: _PATH_SENDMAILCF should 604038032Speter be used instead. 604138032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 604238032Speter of Argonne National Laboratory. 604338032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 604438032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 604538032Speter SunOS: Include <memory.h> to fix warning from util.c. From 604638032Speter James Aldridge of EUnet Ltd. 604738032Speter Solaris: Change STDIR (location of status file) to /etc/mail 604838032Speter in Makefiles. 604938032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 605038032Speter Makefiles. Use NEWDB on Linux instead. 605138032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 605238032Speter exists but behaves differently than other OSes. 605338032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 605438032Speter around the problem. Problem noted by Tom Moore of 605538032Speter NCR Corp. 605638032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 605738032Speter noted by Tom Smith of Digital Equipment Corp. 605838032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 605938032Speter noted by Tom Good of the Community Access Information 606038032Speter Resource Network 606138032Speter SCO 4.2: compile problems caused by a change in the type of 606238032Speter the "length" parameters passed to accept, getpeername, 606338032Speter getsockname, and getsockopt. Adds new compile flags 606438032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. Problem reported 606538032Speter by Tom Good of St. Vincent's North Richmond Community 606638032Speter Mental Health Center Residential Services. 606738032Speter AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. 606838032Speter Suggested by Brett Hogden of Rochester Gas & Electric 606938032Speter Corp. 607038032Speter Linux: avoid compile problem for versions of <setjmp.h> that 607138032Speter #define both setjmp and longjmp.

This makes it possible to create a root 610938032Speter owned file in an arbitrary directory by inserting the symlink 611038032Speter into a writable directory after the initial lstat(2) check 611138032Speter determined that the file did not exist. The only verified 611238032Speter example of a system having these odd semantics for O_EXCL 611338032Speter and symbolic links was HP-UX prior to version 9.07. Most 611438032Speter systems do not have the problem, since a exclusive create 611538032Speter of a file disallows symbolic links. Systems that have been 611638032Speter verified to NOT have the problem include AIX 3.x, *BSD, 611738032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 611838032Speter and Ultrix. This is a potential exposure on systems that 611938032Speter have this bug and which do not have a MAILER-DAEMON alias 612038032Speter pointing at a legitimate account, since this will cause old 612138032Speter mail to be dropped in /var/tmp/dead.letter. 612238032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 612338032Speter if maps or alias files are in world writable directories. 612438032Speter If your system has alias maps in writable directories, it 612538032Speter is potentially possible for an attacker to replace the .db 612638032Speter (or .dir and .pag) files by symbolic links pointing at 612738032Speter another database; this can be used either to expose 612838032Speter information (e.g., by pointing an alias file at /etc/spwd.db 612938032Speter and probing for accounts), or as a denial-of-service attack 613038032Speter (by trashing the password database). The fix disallows 613138032Speter symbolic links entirely when rebuilding alias files or on 613238032Speter maps that are in writable directories, and always warns on 613338032Speter writable directories; 8.9 will probably consider writable 613438032Speter directories to be fatal errors. This does not represent an 613538032Speter exposure on systems that have alias files in unwritable 613638032Speter system directories. 613738032Speter SECURITY: disallow .forward or :include: files that are links (hard 613838032Speter or soft) if the parent directory (or any directory in the 613938032Speter path) is writable by anyone other than the owner. This is 614038032Speter similar to the previous case for user files. This change 614138032Speter should not affect most systems, but is necessary to prevent 614238032Speter an attacker who can write the directory from pointing such 614338032Speter files at other files that are readable only by the owner. 614438032Speter SECURITY: Tighten safechown rules: many systems will say that they 614538032Speter have a safe (restricted to root) chown even on files that 614638032Speter are mounted from another system that allows owners to give 614738032Speter away files. The new rules are very strict, trusting file 614838032Speter ownership only in those few cases where the system has 614938032Speter been verified to be at least as paranoid as necessary. 615038032Speter However, it is possible to relax the rules to partially 615138032Speter trust the ownership if the directory path is not world or 615238032Speter group writable. This might allow someone who has a legitimate 615338032Speter :include: file (referenced directly from /etc/aliases) to 615438032Speter become another non-root user if the :include: file is in a 615538032Speter non-writable directory on an NFS-mounted filesystem where 615638032Speter the local system says that giveaway is denied but it is 615738032Speter actually permitted. I believe this to be a very small set 615838032Speter of cases. If in doubt, do not point :include: aliases at 615938032Speter NFS-mounted filesystems. 616038032Speter SECURITY: When setting a numeric group id using the RunAsUser option 616138032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 616238032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 616338032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 616438032Speter The user id was still set properly. Problem noted by Uli 616538032Speter Pralle of the Technical University of Berlin. 616638032Speter Save the initial gid set for use when checking for if the 616738032Speter PrivacyOptions=restrictmailq option is set. Problem reported 616838032Speter by Wolfgang Ley of DFN-CERT. 616938032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 617038032Speter failure on one message won't affect future messages to the 617138032Speter same host). 617238032Speter IP source route printing had an "off by one" error that would 617338032Speter affect any options that came after the route option. Patch 617438032Speter from Theo de Raadt. 617538032Speter The "Message is too large" error didn't successfully bounce the error 617638032Speter back to the sender. Problem reported by Stephen More of 617738032Speter PSI; patch from Gregory Neil Shapiro of WPI. 617838032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 617938032Speter of 5.1.3); it apparently gets used in multiple ways. 618038032Speter Suggested by John Myers of Portola Communications. 618138032Speter Fix possible extra null byte generated during collection if errors 618238032Speter occur at the beginning of the stream. Patch contributed by 618338032Speter Andrey A. Chernov and Gregory Neil Shapiro. 618438032Speter Code changes to avoid possible reentrant call of malloc/free within 618538032Speter a signal handler. Problem noted by John Beck of Sun 618638032Speter Microsystems. 618738032Speter Move map initialization to be earlier so that check_relay ruleset 618838032Speter will have the latest version of the map data. Problem noted 618938032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 619038032Speter If there are fatal errors during the collection phase (e.g., message 619138032Speter too large) don't send the bogus message. 619238032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 619338032Speter have errors and have owner- aliases. Problem noted by Michael 619438032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 619538032Speter Avoid null pointer dereference on illegal Boundary= parameters in 619638032Speter multipart/mixed Content-Type: header. Problem noted by 619738032Speter Richard Muirden of RMIT University. 619838032Speter Always print error messages during newaliases (-bi) even if the 619938032Speter ErrorMode is not set to "print". Fix from Gregory Neil 620038032Speter Shapiro. 620138032Speter Test mode could core dump if you did a /map lookup in an optional map 620238032Speter that could not be opened. Based on a fix from John Beck of 620338032Speter Sun Microsystems. 620438032Speter If DNS is misconfigured so that the last MX record tried points to 620538032Speter a host that does not have an A record, but other MX records 620638032Speter pointed to something reasonable, don't bounce the message 620738032Speter with a "host unknown" error. Note that this should really 620838032Speter be fixed in the zone file for the domain. Problem noted by 620938032Speter Joe Rhett of Navigist, Inc. 621038032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 621138032Speter the message as having been tried; otherwise the next queue 621238032Speter run will not realize that this is a second attempt and will 621338032Speter retry immediately. Problem noted by Bryan Costales of 621438032Speter Mercury Mail. 621538032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 621638032Speter will be run until the later setting of the clock is reached. 621738032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 621838032Speter Morgan Stanley. 621938032Speter If the load average rises above the cutoff threshold (above which 622038032Speter sendmail will not process the queue at all) during a queue 622138032Speter run, abort the queue run immediately. Problem noted by 622238032Speter Bryan Costales of Mercury Mail. 622338032Speter The variable queue processing algorithm (based on the message size, 622438032Speter number of recipients, message precedence, and job age) was 622538032Speter non-functional -- either the entire queue was processed or 622638032Speter none of the queue was processed. The updated algorithm 622738032Speter does no queue run if a single recipient zero size job will 622838032Speter not be run. 622938032Speter If there is a fatal ("panic") message that will cause sendmail to 623038032Speter die immediately, never hold the error message for future 623138032Speter printing. 623238032Speter Force ErrorMode=print in -bt mode so that all errors are printed 623338032Speter regardless of the setting of the ErrorMode option in the 623438032Speter configuration file. Patch from Gregory Neil Shapiro. 623538032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 623638032Speter routine available in one of the libraries. Use it in conf.h. 623738032Speter The -m (match only) flag now works on host class maps. 623838032Speter If class hash or btree maps are rebuilt, sendmail will now detect 623938032Speter this and reopen the map. Previously, they could give 624038032Speter erroneous results during a single message processing 624138032Speter (but would recover when the next message was received). 624238032Speter Don't delete zero length queue files when doing queue runs until the 624338032Speter files are at least ten minutes old. This avoids a potential 624438032Speter race condition: the creator creates the qf file, getting back 624538032Speter a file descriptor. The queue runner locks it and deletes it 624638032Speter because it is zero length. The creator then writes the 624738032Speter descriptor that is now for a disconnected file, and the 624838032Speter job goes away. Based on a suggestion by Bryan Costales. 624938032Speter When determining the "validated" host name ($_ macro), do a forward 625038032Speter (A) DNS lookup on the result of the PTR lookup and compare 625138032Speter results. If they differ or if the PTR lookup fails, tag the 625238032Speter address as "may be forged". 625338032Speter Log null connections (i.e., hosts that connect but do not do any 625438032Speter substantive activity on the connection before disconnecting; 625538032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 625638032Speter Always permit "writes" to /dev/null regardless of the link count. 625738032Speter This is safe because /dev/null is special cased, and no open 625838032Speter or write is ever actually attempted. Patch from Villy Kruse 625938032Speter of TwinCom. 626038032Speter If a message cannot be sent because of a 552 (exceeded storage 626138032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 626238032Speter was given, don't return the body in the bounce, since there 626338032Speter is a very good chance that the message will double-bounce. 626438032Speter Fix possible line truncation if a quoted-printable had an =00 escape 626538032Speter in the body. Problem noted by Charles Karney of the Princeton 626638032Speter Plasma Physics Laboratory. 626738032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 626838032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 626938032Speter Institute. 627038032Speter The MaxDaemonChildren option wasn't applying to queue runs as 627138032Speter documented. Note that this increases the potential denial 627238032Speter of service problems with this option: an attacker can 627338032Speter connect many times, and thereby lock out queue runs as well 627438032Speter as incoming connections. If you use this option, you should 627538032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 627638032Speter to avoid this attack. Failure to limit noted by Matthew 627738032Speter Dillon of BEST Internet Communications. 627838032Speter Always give a message in newaliases if alias files cannot be 627938032Speter opened instead of failing silently. Suggested by Gregory 628038032Speter Neil Shapiro. This change makes the code match the O'Reilly 628138032Speter book (2nd edition). 628238032Speter Some older versions of the resolver could return with h_errno == -1 628338032Speter if no name server could be reached, causing mail to bounce 628438032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 628538032Speter John Beck of SunSoft. 628638032Speter If a :include: file is owned by a user that does not have an entry 628738032Speter in the passwd file, sendmail could dereference a null pointer. 628838032Speter Problem noted by Satish Mynam of Sun Microsystems. 628938032Speter Take precautions to make sure that the SMTP protocol cannot get out 629038032Speter of sync if (for example) an alias file cannot be opened. 629138032Speter Fix a possible race condition that can cause a SIGALRM to come in 629238032Speter immediately after a SIGHUP, causing the new sendmail to die. 629338032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 629438032Speter from Villy Kruse of TwinCom. 629538032Speter Ignore improperly formatted SMTP reply codes. Previously these were 629638032Speter partially processed, which could cause confusing error 629738032Speter returns. 629838032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 629938032Speter on some architectures. 630038032Speter Portability: 630138032Speter A/UX: from Jim Jagielski of NASA/GSFC. 630238032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 630338032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 630438032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 630538032Speter defined. Problem reported by A Sun of the University 630638032Speter of Washington. 630738032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 630838032Speter the system rather than guessing at compile time. 630938032Speter Patch contributed by John Beck of Sun Microsystems. 631038032Speter Intel Paragon: from Wendy Lin of Purdue University. 631138032Speter GNU Hurd: from Miles Bader of the GNU project. 631238032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 631338032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 631438032Speter Unfortunately releasing them opens a race condition, 631538032Speter but there appears to be no fix for this. Patch from 631638032Speter Gregory Neil Shapiro. 631738032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 631838032Speter Solaris: a bug in strcasecmp caused characters with the 631938032Speter high order bit set to apparently randomly match 632038032Speter letters -- for example, $| (0233) matches "i" and "I". 632138032Speter Problem noted by John Gregson of the University of 632238032Speter Cambridge. 632338032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 632438032Speter Kari Hurtta. 632538032Speter IRIX 6.x: Create Makefiles for systems that claim to be 632638032Speter IRIX64 but are 6.2 or higher (so use the regular 632738032Speter IRIX Makefile). 632838032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 632938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 633038032Speter CONFIG: Some canonification was still done for UUCP-like addresses 633138032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 633238032Speter Brian Candler. 633338032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 633438032Speter local names as local. Problem noted by Jeff Polk of BSDI; 633538032Speter fix provided by Gregory Neil Shapiro. 633638032Speter CONFIG: The "local:user" syntax entries in mailertables and other 633738032Speter "mailer:user" syntax locations returned an incorrect value 633838032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 633938032Speter CONFIG: Retain "+detail" information when forwarding mail to a 634038032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 634138032Speter Guenther of Gustavus Adolphus College. 634238032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 634338032Speter rules are the same as for aliasing. Based on a patch from 634438032Speter Gregory Neil Shapiro. 634538032Speter CONFIG: Break up parsing rules into several pieces; this should 634638032Speter have no functional change in this release, but makes it 634738032Speter possible to have better anti-spam rulesets in the future. 634838032Speter CONFIG: Disallow double dots in host names to avoid having the 634938032Speter HostStatusDirectory store status under the wrong name. 635038032Speter In some cases this can be used as a denial-of-service attack. 635138032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 635238032Speter Gregory Neil Shapiro. 635338032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 635438032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 635538032Speter don't include From_, and convert to 8-bit). Suggestions 635638032Speter from Kimmo Suominen and Roderick Schertler. 635764562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 635838032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 635938032Speter was specified, even when it wasn't. 636038032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 636138032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 636238032Speter "slip in" a symbolic link between the lstat(2) call and the 636338032Speter exclusive open. This is only a problem on System V derived 636438032Speter systems that allow an exclusive create on files that are 636538032Speter symbolic links pointing nowhere. 636638032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 636738032Speter not reset back to root, which on some systems would cause 636838032Speter later mailboxes to fail. Also, any partial message would 636938032Speter not be truncated, which could result in repeated deliveries. 637038032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 637138032Speter developers). 637238032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 637338032Speter change to the sendmail map code was made in 8.8.3. Problem 637438032Speter noted by Gregory Neil Shapiro. 637538032Speter MAKEMAP: Give warnings on file problems such as map files that are 637690792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 637738032Speter often run as root and hence has the potential for the same 637838032Speter sorts of problems as alias rebuilds. 637938032Speter MAKEMAP: Change compilation so that it will link properly on 638038032Speter NEXTSTEP. 638138032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 638238032Speter Accept an optional list of arguments following the server 638338032Speter name for the ETRN arguments to use (instead of $=w).

This 638738032Speter Perl script converts GECOS information in the /etc/passwd 638838032Speter file into aliases, allowing for faster access to full name 638938032Speter lookups; it is also clever about adding aliases (to root) 639038032Speter for system accounts. 639138032Speter NEW FILES: 639238032Speter src/safefile.c 639338032Speter cf/ostype/gnuhurd.m4 639438032Speter cf/ostype/irix6.m4 639538032Speter contrib/passwd-to-alias.pl 639638032Speter src/Makefiles/Makefile.IRIX64.6.1 639738032Speter src/Makefiles/Makefile.IRIX64.6.x 639838032Speter RENAMED FILES: 639938032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 640038032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 640138032Speter 640264562Sgshapiro8.8.5/8.8.5 1997/01/21 640338032Speter SECURITY: Clear out group list during startup. Without this, sendmail 640438032Speter will continue to run with the group permissions of the caller, 640538032Speter even if RunAsUser is specified. 640638032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 640738032Speter to any known attack, but it's best to be conservative. 640838032Speter Suggested by Peter Wemm of DIALix. 640938032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 641038032Speter security implications. Patch from Alex Garthwaite of the 641138032Speter University of Pennsylvania. 641238032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 641338032Speter would truncate the address after "Full". Although the -f 641438032Speter syntax is incorrect (since it is in the envelope, it 641538032Speter shouldn't have comments and full names), the failure mode 641638032Speter was unnecessarily awful. 641738032Speter Fix a possible null pointer dereference when converting 8-bit data 641838032Speter to a 7-bit format. Problem noted by Jim Hutchins of 641938032Speter Sandia National Labs and David James of British Telecom. 642038032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 642138032Speter runs. Although this really shouldn't be used (F=9 is for 642238032Speter final delivery only, and using it on an SMTP mailer makes 642338032Speter it possible for a message to be converted from 8->7->8->7 642438032Speter bits several times), it shouldn't have failed with a syserr. 642538032Speter Problem noted by Eric Hagberg of Morgan Stanley. 642638032Speter _Really_ fix the multiple :maildrop code in the user database 642738032Speter module. Patch from Roy Mongiovi of Georgia Tech. 642838032Speter Let F lines in the configuration file actually read root-only 642938032Speter files if the configuration file is safe. Based on a 643038032Speter patch from Keith Reynolds of SCO. 643138032Speter ETRN followed by QUIT would hold the connection open until the queue 643238032Speter run completed. Problem noted by Truck Lewis of TDK 643338032Speter Semiconductor Corp. 643438032Speter It turns out that despite the documentation, the TCP wrappers library 643538032Speter does _not_ log rejected connections. Do the logging ourselves. 643638032Speter Problem noted by Fletcher Mattox of the University of Texas 643738032Speter at Austin. 643838032Speter If sendmail finds a qf file in its queue directory that is an unknown 643938032Speter version (e.g., when backing out to an old version), the 644038032Speter error is reported on every queue run. Change it to only 644138032Speter give the error once (and rename the qf => Qf). Patch from 644238032Speter William A. Gianopoulos of Raytheon Company. 644338032Speter Start a new session when doing background delivery; currently it 644438032Speter ignored signals but didn't start a new signal, that caused 644538032Speter some problems if a background process tried to send mail 644638032Speter under certain circumstances. Problem noted by Eric Hagberg 644738032Speter of Morgan Stanley; fix from Kari Hurtta. 644838032Speter Simplify test for skipping a queue run to just check if the current 644938032Speter load average is >= the queueing load average. Previously 645038032Speter the check factored in some other parameters that caused it 645138032Speter to essentially never skip the queue run. Patch from Bryan 645238032Speter Costales. 645338032Speter If the SMTP server is running in "nullserver" mode (that is, it is 645438032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 645538032Speter (25) commands; this helps prevent a bad guy from putting 645638032Speter you into a tight loop as a denial-of-service attack. Based 645738032Speter on an e-mail conversation with Brad Knowles of AOL. 645838032Speter Slow down when too many "light weight" commands have been issued; 645938032Speter this helps prevent a class of denial-of-service attacks. 646038032Speter The current values and defaults are: 646138032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 646238032Speter MAXHELOCOMMANDS 3 HELO, EHLO 646338032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 646438032Speter MAXETRNCOMMANDS 8 ETRN 646538032Speter These will probably be configurable in a future release. 646638032Speter On systems that have uid_t typedefed to be an unsigned short, programs 646738032Speter that had the F=S flag and no U= equate would be invoked with 646838032Speter the real uid set to 65535 rather than being left unchanged. 646938032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 647038032Speter by Steve Hubert of the University of Washington, Seattle. 647138032Speter Mail that was Quoted-Printable encoded and had a soft line break on 647238032Speter the last line (i.e., an incomplete continuation) had the last 647338032Speter line dropped. Since this appears to be illegal it isn't 647438032Speter clear what to do with it, but flushing the last line seems 647538032Speter to be a better "fail soft" approach. Based on a patch from 647638032Speter Eric Hagberg. 647738032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 647838032Speter bogus HELO command still causes the "Polite people say HELO 647938032Speter first" error message. Problem pointed out by Chris Thomas 648038032Speter of UCLA; patch from John Beck of SunSoft. 648138032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 648271345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 648371345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 648471345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 648538032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 648638032Speter in a DATA transaction to be sticky; these can occur because 648738032Speter a message is too large, and smaller messages should still go 648838032Speter through. Problem noted by Matt Dillon of Best Internet 648938032Speter Communications. 649038032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 649138032Speter had been successfully delivered to the envelope sender. 649238032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 649338032Speter Gregory Neil Shapiro of WPI. 649438032Speter Give better diagnostics on long alias lines. Based on code contributed 649538032Speter by Patrick Gosling of the University of Cambridge. 649638032Speter Increase the number of virtual interfaces that will be probed for 649738032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 649838032Speter PORTABILITY: 649938032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 650038032Speter Toshiaki Nomura of Fujitsu Limited. 650138032Speter SunOS with LDAP support: compile problems with struct timeval. 650238032Speter Patch from Nick Cuccia of TCSI Corporation. 650338032Speter SCO: from Keith Reynolds of SCO. 650438032Speter Solaris: kstat load average computation wasn't being used. 650538032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 650638032Speter (Moscow). 650738032Speter OpenBSD: from Jason Downs of teeny.org. 650838032Speter Altos System V: from Tim Rice. 650938032Speter Solaris 2.5: from Alan Perry of SunSoft. 651038032Speter Solaris 2.6: from John Beck of SunSoft. 651138032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 651238032Speter of Pratt & Whitney <miorelli@pweh.com>. 651338032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 651438032Speter _just_right_ yet. Tweak it again. I'll omit the names 651538032Speter of the "contributors" (quantity two) in this one case. 651638032Speter As of now, NO MORE DISCUSSION about the syntax of the 651738032Speter Received: line. 651838032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 651938032Speter it never inserts that class into the output file. Fix it 652038032Speter so it will honor EXPOSED_USER but will _not_ include root 652138032Speter automatically in this class. Problem noted by Ronan KERYELL 652238032Speter of Centre de Recherche en Informatique de l'�cole Nationale 652338032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 652438032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 652538032Speter such as LUSER_RELAY. This change permits the following 652638032Speter syntaxes: ``local:'' will send to the same user on the 652738032Speter local machine (e.g., in a mailertable entry for "host", 652838032Speter ``local:'' will cause an address addressed to user@host to 652938032Speter go to user on the local machone). ``local:user'' will send 653038032Speter to the named user on the local machine. ``local:user@host'' 653138032Speter is equivalent to ``local:user'' (the host is ignored). In 653238032Speter all cases, the original user@host is passed in $@ (i.e., the 653338032Speter detail information). Inspired by a report from Michael Fuhr. 653438032Speter CONFIG: Strip quotes from the first word of an "error:" host 653538032Speter indication. This lets you set (for example) the LUSER_RELAY 653638032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 653738032Speter of the \" so that the resulting string is properly quoted. 653838032Speter Problem noted by Gregory Neil Shapiro of WPI. 653938032Speter OP.ME: documentation was inconsistent about whether sendmail did a 654038032Speter NOOP or a RSET to probe the connection (it does a RSET). 654138032Speter Inconsistency noted by Deeran Peethamparam. 654238032Speter OP.ME: insert additional blank pages so it will print properly on 654338032Speter a duplex printer. From Matthew Black of Cal State University, 654438032Speter Long Beach. 654538032Speter 654664562Sgshapiro8.8.4/8.8.4 1996/12/02 654738032Speter SECURITY: under some circumstances, an attacker could get additional 654838032Speter permissions by hard linking to files that were group 654938032Speter writable by the attacker. The solution is to disallow any 655038032Speter files that have hard links -- this will affect .forward, 655138032Speter :include:, and output files. Problem noted by Terry 655238032Speter Kyriacopoulos of Interlog Internet Services. As a 655338032Speter workaround, set UnsafeGroupWrites -- always a good idea. 655438032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 655538032Speter is, it is possible to do a denial-of-service attack on 655638032Speter MX hosts that rely on the use of the null MX list. There 655738032Speter is no danger if you have this option turned off (the default). 655838032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 655938032Speter unsafe. I know of no specific attack against this, although 656038032Speter a denial-of-service attack is probably possible, but in theory 656138032Speter you should not be able to safely tweak anything that affects 656238032Speter the permissions that are used when mail is delivered. 656338032Speter Purgestat could go into an infinite loop if one of the host status 656438032Speter directories somehow became empty. Problem noted by Roy 656538032Speter Mongiovi of Georgia Tech. 656638032Speter Processes got "lost" when counting children due to a race condition. 656738032Speter This caused "proc_list_probe: lost pid" messages to be logged. 656838032Speter Problem noted by several people. 656938032Speter On systems with System V SIGCLD child signal semantics (notably AIX 657038032Speter and HP-UX), mail transactions would print the message "451 657138032Speter SMTP-MAIL: lost child: No child processes". Problem noted 657238032Speter by several people. 657338032Speter Miscellaneous compiler warnings on picky compilers (or when setting 657438032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 657538032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 657638032Speter not be persistent between runs, since they are based on the 657738032Speter message rather than the host. Problem noted by Matt Dillon 657838032Speter of Best Internet Communications. 657938032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 658038032Speter of NCR (a.k.a., AT&T Global Information Solutions). 658138032Speter Avoid the possibility of having a child daemon run to completion 658238032Speter (including closing the SMTP socket) before the parent has 658338032Speter had a chance to close the socket; this can cause the parent 658438032Speter to hang for a long time waiting for the socket to drain. 658538032Speter Patch from Don Lewis of TDK Semiconductor. 658638032Speter If the fork() failed in a queue run, the queue runners would not be 658738032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 658838032Speter Some error conditions in ETRN could cause output without an SMTP 658938032Speter status code. Problem noted by Don Lewis. 659038032Speter Multiple :maildrop addresses in the user database didn't work properly. 659138032Speter Patch from Roy Mongiovi of Georgia Tech. 659238032Speter Add ".db" automatically onto any user database spec that does not 659338032Speter already have it; this is for consistency with makemap, the 659438032Speter K line, and the documentation. Inconsistency pointed out 659538032Speter by Roy Mongiovi. 659638032Speter Allow sendmail to be properly called in nohup mode. Patch from 659738032Speter Kyle Jones of UUNET. 659838032Speter Change ETRN to ignore but still update host status files; previously 659938032Speter it would ignore them and not save the updated status, which 660038032Speter caused stale information to be maintained. Based on a patch 660138032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 660238032Speter ETRN ignore the MinQueueAge option. 660338032Speter Patch long term host status to recover more gracefully from an empty 660438032Speter host status file condition. Patch from NAKAMURA Motonori 660538032Speter of Kyoto University. 660638032Speter Several patches to signal handling code to fix potential race 660738032Speter conditions from Don Lewis. 660838032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 660938032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 661038032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 661138032Speter compile flag; use NETINET instead. Solution based on a 661238032Speter patch from Bryan Costales. 661338032Speter PORTABILITY FIXES: 661438032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 661538032Speter /etc/security/passwd file when called as root. This 661638032Speter is very slow on some systems. To speed it up, use the 661738032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 661838032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 661938032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 662038032Speter Glicker of Burrelle's Information Service. 662138032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 662238032Speter from Makoto MATSUSHITA of Osaka University. 662338032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 662438032Speter Leeds University and SASABE Tetsuro of the University 662538032Speter of Tokyo. 662638032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 662738032Speter Services, Inc. 662838032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 662938032Speter I believe this to have only been a problem if you 663038032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 663138032Speter to stick with /etc/sendmail.cf as your One True Path. 663238032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 663338032Speter Martin Laubach of the Technischen Universit�t Wien. 663438032Speter CONFIG: change default Received: line to be multiple lines rather 663538032Speter than one long one. By popular demand. 663638032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 663738032Speter from Jerome Berkman of U.C. Berkeley. 663838032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 663938032Speter to take a very long time. Problem noted by Yoshiro YONEYA 664038032Speter of NTT Software Corporation. 664138032Speter CONTRIB: add etrn.pl, contributed by John Beck. 664238032Speter NEW FILES: 664338032Speter contrib/etrn.pl 664438032Speter 664564562Sgshapiro8.8.3/8.8.3 1996/11/17 664638032Speter SECURITY: it was possible to get a root shell by lying to sendmail 664738032Speter about argv[0] and then sending it a signal. Problem noted 664838032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 664938032Speter best-of-security list. 665038032Speter Log sendmail binary version number in "Warning: .cf version level 665138032Speter (%d) exceeds program functionality (%d) message" -- this 665238032Speter should make it clearer to people that they are running 665338032Speter the wrong binary. 665438032Speter Fix a problem that occurs when you open an SMTP connection and then 665538032Speter do one or more ETRN commands followed by a MAIL command; at 665638032Speter the end of the DATA phase sendmail would incorrectly report 665738032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 665838032Speter noted by Eric Bishop of Virginia Tech. 665938032Speter When doing text-based host canonification (typically /etc/hosts 666038032Speter lookup), a null host name would match any /etc/hosts entry 666138032Speter with space at the end of the line. Problem noted by Steve 666238032Speter Hubert of the University of Washington, Seattle. 666338032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 666438032Speter Problem reported by Tom Smith of Digital Equipment Corp. 666538032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 666638032Speter size PACKETSZ (512) is not sufficient for some nameserver 666738032Speter answers containing very many resource records. The resolver 666838032Speter may also switch to TCP and retry if it detects UDP packet 666938032Speter overflow. Also, allow for the fact that the resolver 667038032Speter routines res_query and res_search return the size of the 667138032Speter *un*truncated answer in case the supplied answer buffer it 667238032Speter not big enough to accommodate the entire answer. Patch from 667338032Speter Eric Wassenaar. 667438032Speter Improvements to MaxDaemonChildren code. If you think you have too 667538032Speter many children, probe the ones you have to verify that they 667638032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 667738032Speter Also, do this probe before growing the vector of children 667838032Speter pids; this previously caused the vector to grow indefinitely 667938032Speter due to a race condition. Problem reported by Kyle Jones of 668038032Speter UUNET. 668138032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 668238032Speter O_EXLOCK to zero; this fools the map compilation code into 668338032Speter thinking that it can avoid race conditions by locking on open. 668438032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 668538032Speter Leif Erlingsson of Data Lege. 668638032Speter Always call res_init() on startup (if compiled in, of course) to 668738032Speter allow the sendmail.cf file to tweak resolver flags; without 668838032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 668938032Speter Andrew Sun of Merrill Lynch. 669038032Speter Improvements to host status printing code. Suggested by Steve Hubert 669138032Speter of the University of Washington, Seattle. 669238032Speter Change MinQueueAge option processing to do the check for the job age 669338032Speter when reading the queue file, rather than at the end; this 669438032Speter avoids parsing the addresses, which can do DNS lookups. 669538032Speter Problem noted by John Beck of InReference, Inc. 669638032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 669738032Speter properly escaped. Problem noted by Peter Nilsson of the 669838032Speter University of Linkoping. 669938032Speter In some cases, sendmail would retain root permissions during queue 670038032Speter runs even if RunAsUser was set. Problem noted by Mark 670138032Speter Thomas of Mark G. Thomas Consulting. 670238032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 670338032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 670438032Speter the envelope, and the receiving SMTP server speaks DSN, then 670538032Speter the DSN would be both generated locally and propagated to the 670638032Speter other end. 670738032Speter The U= mailer field didn't correctly extract the group id if the 670838032Speter user id was numeric. Problem noted by Kenneth Herron of 670938032Speter MCI Telecommunications Communications. 671038032Speter If a message exceeded the fixed maximum size on input, the body of 671138032Speter the message was included in the bounce. Note that this did 671238032Speter not occur if it exceeded the maximum _output_ size. Problem 671338032Speter reported by Kyle Jones of UUNET. 671438032Speter PORTABILITY FIXES: 671538032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 671638032Speter AIX4 defines to use seteuid(2) instead, which 671738032Speter works on 4.1 as well as 4.2. Problem noted by 671838032Speter H�kan Lindholm of interAF, Sweden. 671938032Speter AIX4: use tzname[] vector to determine time zone name. 672038032Speter Patch from NAKAMURA Motonori of Kyoto University. 672138032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 672238032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 672338032Speter Solaris: kstat(3k) support for retrieving the load average. 672438032Speter This adds the LA_KSTAT definition for LA_TYPE. 672538032Speter The outline of the implementation was contributed 672638032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 672738032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 672838032Speter declaration of struct rusage at the top of conf.h; 672938032Speter change it to only be included if you are using gcc, 673038032Speter which is apparently the only compiler that requires 673138032Speter it in the first place. Problem noted by Jeff 673238032Speter Earickson of Colby College. 673338032Speter IRIX: don't default to using gcc. IRIX is a civilized 673438032Speter operating system that comes with a decent compiler 673538032Speter by default. Problem noted by Barry Bouwsma and 673638032Speter Kari Hurtta. 673738032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 673838032Speter consistency with other local mailers. Inconsistency 673938032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 674038032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 674138032Speter overhead) as part of the bestmx_is_local feature, the 674238032Speter domain part was dropped from the name. Patch from Steve 674338032Speter Hubert of the University of Washington, Seattle. 674438032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 674538032Speter end up being translated to the null host name, which would 674638032Speter return any entry in /etc/hosts that had a space at the end 674738032Speter of the line. Problem noted by Steve Hubert of the 674838032Speter University of Washington, Seattle. 674938032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 675038032Speter Polytechnic Institute. 675138032Speter MAKEMAP: tweak hash and btree parameters for better performance. 675238032Speter Patch from Matt Dillon of Best Internet Communications. 675338032Speter NEW FILES: 675438032Speter src/Makefiles/Makefile.Linux.ppc 675538032Speter cf/ostype/aix4.m4 675638032Speter cf/ostype/mklinux.m4 675738032Speter 675864562Sgshapiro8.8.2/8.8.2 1996/10/18 675938032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 676038032Speter changed the code but didn't fix the problem. 676138032Speter PORTABILITY FIXES: 676238032Speter Solaris: Don't use the system getusershell(3); it can 676338032Speter apparently corrupt the heap in some circumstances. 676438032Speter Problem found by Ken Pizzini of Spry, Inc. 676538032Speter OP.ME: document several mailer flags that were accidentally omitted 676638032Speter from this document.

Problem noted 677238032Speter by Dan Bernstein of the University of Illinois at Chicago. 677338032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 677438032Speter message could overflow a buffer if it was converted back 677538032Speter to 8 bits. This caused core dumps and has the potential 677638032Speter for a remote attack. Problem first noted by Gregory Shapiro 677738032Speter of WPI. 677838032Speter Avoid duplicate deliveries of error messages on systems that don't 677938032Speter have flock(2) support. Patch from Motonori Nakamura of 678038032Speter Kyoto University. 678138032Speter Ignore null FallBackMX (V) options. If this option is null (as 678238032Speter opposed to undefined) it can cause "null signature" syserrs 678338032Speter on illegal host names. 678438032Speter If a Base64 encoded text/plain message has no trailing newline in 678538032Speter the encoded text, conversion back to 8 bits will drop the 678638032Speter final line. Problem noted by Pierre David. 678738032Speter If running with a RunAsUser, sendmail would give bogus "cannot 678838032Speter setuid" (or seteuid, or setreuid) messages on some systems. 678938032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 679038032Speter Always print error messages in -bv mode -- previously, -bv would 679138032Speter be absolutely silent on errors if the error mode was sent 679238032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 679338032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 679438032Speter term host status. This is necessary because it is common 679538032Speter to do this when you know a host has just come back up. 679638032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 679738032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 679838032Speter University of Leicester. 679938032Speter If a service (such as NIS) is specified as the last entry in the 680038032Speter service switch, but that service is not compiled in, sendmail 680138032Speter would return a temporary failure when an entry was not found 680238032Speter in the map. This caused the message to be queued instead of 680338032Speter bouncing immediately. Problem noted by Harry Edmon of the 680438032Speter University of Washington. 680538032Speter PORTABILITY FIXES: 680638032Speter Solaris 2.3 had compilation problems in conf.c. Several 680738032Speter people pointed this out. 680838032Speter NetBSD from Charles Hannum of MIT. 680938032Speter AIX4 improvements based on info from Steve Bauer of South 681038032Speter Dakota School of Mines & Technology. 681138032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 681238032Speter Patch from Gil Kloepfer Jr. 681338032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 681438032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 681538032Speter were also in $=w. Problem noted by Zoltan Basti of 681638032Speter Softec. 681738032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 681838032Speter on a patch from Eric Hagberg of Morgan Stanley. 681938032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 682038032Speter of Stanford via Robert La Ferla. 682138032Speter 682264562Sgshapiro8.8.0/8.8.0 1996/09/26 682338032Speter Under some circumstances, Bcc: headers would not be properly 682438032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 682538032Speter Log a warning if the sendmail daemon is invoked without a full 682638032Speter pathname, which prevents "kill -1" from working. I was 682738032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 682838032Speter Fix small buffer overflow. Since the data in this buffer was not 682938032Speter read externally, there was no security problem (and in fact 683038032Speter probably wouldn't really overflow on most compilers). Pointed 683138032Speter out by KIZU takashi of Osaka University. 683238032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 683338032Speter if a FallbackMXHost was specified in the configuration file 683438032Speter -- all mail would be sent to the fallback even if the original 683538032Speter host was accessible. Pointed out by Munenari Hirayama of 683638032Speter NSC (Japan). 683738032Speter A message that didn't terminate with a newline would (sometimes) not 683838032Speter have the trailing "." added properly in the SMTP dialogue, 683938032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 684038032Speter The DaemonPortOptions suboption to bind to a particular address was 684138032Speter incorrect and nonfunctional due to a misunderstanding of the 684238032Speter semantics of binding on a passive socket. Patch from 684338032Speter NIIBE Yutaka of Mitsubishi Research Institute. 684438032Speter Increase the number of MX hosts for a single name to 100 to better 684538032Speter handle the truly huge service providers such as AOL, which 684638032Speter has 13 at the moment (and climbing). In order to avoid 684738032Speter trashing memory, the buffer for all names has only been 684838032Speter slightly increased in size, to 12.8K from 10.2K -- this means 684938032Speter that if a single name had 100 MX records, the average size 685038032Speter of those records could not exceed 128 bytes. Requested by 685138032Speter Brad Knowles of America On Line. 685238032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 685338032Speter Urged by Dan Bernstein of U.C. Berkeley. 685438032Speter Print q_statdate and q_specificity in address structure debugging 685538032Speter printout. 685638032Speter Expand MCI structure flag bits for debugging output. 685738032Speter Support IPv6-style domain literals, which can have colons between 685838032Speter square braces. 685938032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 686038032Speter this is an attempt to track down a bug that one person seems 686138032Speter to be having (it may be a Solaris bug!). 686238032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 686338032Speter this caused the NOTIFY info to sometimes be lost. Problem 686438032Speter pointed out by Claus Assmann of the 686538032Speter Christian-Albrechts-University of Kiel. 686638032Speter The statistics gathered in the sendmail.st file were too high; in 686738032Speter some cases failures (e.g., user unknown or temporary failure) 686838032Speter would count as a delivery as far as the statistics were 686938032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 687038032Speter Systems that don't have flock() would not send split envelopes in 687138032Speter the initial run. Problem pointed out by Leonard Zubkoff of 687238032Speter Dandelion Digital. 687338032Speter Move buffer overflow checking -- these primarily involve distrusting 687438032Speter results that may come from NIS and DNS. 687538032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 687638032Speter include <paths.h> and hence had the wrong pathnames for a few 687738032Speter things like /var/tmp. Reported by Matthew Green. 687838032Speter Conditions were reversed for the Priority: header, resulting in all 687938032Speter values being interpreted as non-urgent except for non-urgent, 688038032Speter which was interpreted as normal. Patch from Bryan Costales. 688138032Speter The -o (optional) flag was being ignored on hash and btree maps 688238032Speter since 8.7.2. Fix from Bryan Costales. 688338032Speter Content-Types listed in class "q" will always be encoded as 688438032Speter Quoted-Printable (or more accurately, will never be encoded 688538032Speter as base64). The class can have primary types (e.g., "text") 688638032Speter or full types (e.g., "text/plain"). Based on a suggestion by 688738032Speter Marius Olafsson of the University of Iceland. 688838032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 688938032Speter dialogue) so it can be passed to programs in mailers. 689038032Speter Define ${bodytype} to be the body type (from the -B flag or the 689138032Speter BODY= ESMTP parameter) so it can be passed to programs in 689238032Speter mailers. 689338032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 689438032Speter flag is set in the mailer descriptor. Suggested by John 689538032Speter Myers of CMU. 689638032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 689738032Speter The command takes a host name; data for that host is 689838032Speter immediately (and asynchronously) flushed. Because this shares 689938032Speter the -qR implementation, other hosts may be attempted, but 690038032Speter there should be no security implications. Implementation 690138032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 690238032Speter Add three new command line flags to pass in DSN parameters: -V envid 690338032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 690438032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 690538032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 690638032Speter that the -N flag applies to all recipients; there is no way 690738032Speter to specify per-address notifications on the command line, 690838032Speter nor is there an equivalent for the ORCPT= per-address 690938032Speter parameter. 691038032Speter Restore LogLevel option to be safe (it can only be increased); 691138032Speter apparently I went into paranoid mode between 8.6 and 8.7 691238032Speter and made it unsafe. Pointed out by Dabe Murphy of the 691338032Speter University of Maryland. 691438032Speter New logging on log level 15: all SMTP traffic. Patches from 691538032Speter Andrew Gross of San Diego Supercomputer Center. 691638032Speter NetInfo property value searching code wasn't stopping when it found 691738032Speter a match. This was causing the wrong values to be found (and 691838032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 691938032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 692038032Speter out by Bill Wisner of Electronics for Imaging that you can't 692138032Speter use the bracket address form for the MAIL_HUB macro, since 692238032Speter that causes the brackets to remain in the envelope recipient 692338032Speter address used for delivery. The simple fix (stripping off the 692438032Speter brackets in the config file) breaks the use of IP literal 692538032Speter addresses. This flag will solve that problem. 692638032Speter Add MustQuoteChars option. This is a list of characters that must 692738032Speter be quoted if they are found in the phrase part of an address 692838032Speter (that is, the full name part). The characters @,;:\()[] are 692938032Speter always in this list and cannot be removed. The default is 693038032Speter this list plus . and ' to match RFC 822. 693138032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 693238032Speter that do not include a host name for back compatibility with 693338032Speter some stupid SMTP clients. Setting this violates RFC 1123 693438032Speter section 5.2.5. 693538032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 693638032Speter rejecting connections if it has more than this many 693738032Speter outstanding children accepting mail. Note that you may 693838032Speter see more processes than this because of outgoing mail; this 693938032Speter is for incoming connections only. 694038032Speter Add ConnectionRateThrottle option. If set to a positive value, the 694138032Speter number of incoming SMTP connections that will be permitted 694238032Speter in a single second is limited to this number. Connections are 694338032Speter not refused during this time, just deferred. The intent is to 694438032Speter flatten out demand so that load average limiting can kick in. 694538032Speter It is less radical than MaxDaemonChildren, which will stop 694638032Speter accepting connections even if all the connections are idle 694738032Speter (e.g., due to connection caching). 694838032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 694938032Speter specifies how long cached information about the state of a 695038032Speter host will be kept before they are considered stale and the 695138032Speter host is retried. If you are using persistent host status 695238032Speter (i.e., the HostStatusDirectory option is set) this will apply 695338032Speter between runs; otherwise, it applies only within a single queue 695438032Speter run and hence is useful only for hosts that have large queues 695538032Speter that take a very long time to run. 695638032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 695738032Speter into being a single line even if they had newlines in them 695838032Speter when read. This is to get around a botch in Lotus Notes. 695938032Speter Text class maps were totally broken -- if you ever retrieved the last 696038032Speter item in a table it would be truncated. Problem noted by 696138032Speter Gregory Neil Shapiro of WPI. 696238032Speter Extend the lines printed by the mailq command (== the -bp flag) when 696338032Speter -v is given to 120 characters; this allows more information 696438032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 696538032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 696638032Speter this was treated as end-of-input. Problem noted by Bryan 696738032Speter Costales. 696838032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 696938032Speter to the queue file. Fix from John Hughes of Atlantic 697038032Speter Technologies, Inc. 697138032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 697238032Speter if this happens in a queue run it can cause nasty delays. 697338032Speter Problem noted by Mark Horton of AT&T. 697438032Speter If userdb entries pointed to userdb entries, and there were multiple 697538032Speter values for a given key, the database cursor would get 697638032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 697738032Speter of Georgia Tech. Fixed by reading all the values and creating 697838032Speter a comma-separated list; thus, the -v output will be somewhat 697938032Speter different for this case. 698038032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 698138032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 698238032Speter of Stanford University. 698338032Speter When envelopes were split due to aliases with owner- aliases, and 698438032Speter there was some error on one of the lists, more than one of 698538032Speter the owners would get the message. Problem pointed out by 698638032Speter Roy Mongiovi of Georgia Tech. 698738032Speter Detect excessive recursion in macro expansions, e.g., $X defined 698838032Speter in terms of $Y which is defined in terms of $X. Problem 698938032Speter noted by Bryan Costales; patch from Eric Wassenaar. 699038032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 699138032Speter some cases get trashed causing bogus From_ lines. Fix from 699238032Speter Kyle Jones of UUNET. 699338032Speter When doing load average initialization, if the nlist call for avenrun 699438032Speter failed, the second and subsequent lookups wouldn't notice 699538032Speter that fact causing bogus load averages to be returned. Noted 699638032Speter by Casper Dik of Sun Holland. 699738032Speter Fix problem with incompatibility with some versions of inet_aton that 699838032Speter have changed the return value to unsigned, so a check for an 699938032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 700038032Speter This could cause mail to addresses such as [foo.com] to bounce 700138032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 700238032Speter Pasteur Institute. 700338032Speter DSNs were inconsistent if a failure occurred during the DATA phase 700438032Speter rather than the RCPT phase: the Action: would be correct, but 700538032Speter the detailed status information would be wrong. Problem noted 700638032Speter by Bob Snyder of General Electric Company. 700738032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 700838032Speter that this is the initial MUA->MTA submission. The flag current 700938032Speter does nothing, but in future releases (when MUAs start using 701038032Speter these flags) it will probably turn on things like DNS 701138032Speter canonification. 701238032Speter Default end-of-line string (E= specification on mailer [M] lines) 701338032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 701438032Speter mailers. 701538032Speter Change the internal definition for the *file* and *include* mailers 701638032Speter to have $u in the argument vectors so that they aren't 701738032Speter misinterpreted as SMTP mailers and thus use \r\n line 701838032Speter termination. This will affect anyone who has redefined 701938032Speter either of these in their configuration file. 702038032Speter Don't assume that IDENT servers close the connection after a query; 702138032Speter responses can be newline terminated. From Terry Kennedy of 702238032Speter St. Peter's College. 702338032Speter Avoid core dumps on erroneous configuration files that have 702438032Speter $#mailer with nothing following. From Bryan Costales. 702538032Speter Avoid null pointer dereference with high debug values in unlockqueue. 702638032Speter Fix from Randy Martin of Clemson University. 702738032Speter Fix possible buffer overrun when expanding very large macros. Fix 702838032Speter from Kyle Jones of UUNET. 702938032Speter After 25 EXPN or VRFY commands, start pausing for a second before 703038032Speter processing each one. This avoids a certain form of denial 703138032Speter of service attack. Potential attack pointed out by Bryan 703238032Speter Costales. 703338032Speter Allow new named (not numbered!) config file rules to do validity 703438032Speter checking on SMTP arguments: check_mail for MAIL commands and 703538032Speter check_rcpt for RCPT commands. These rulesets can do anything 703638032Speter they want; their result is ignored unless they resolve to the 703738032Speter $#error mailer, in which case the indicated message is printed 703838032Speter and the command is rejected. Similarly, the check_compat 703938032Speter ruleset is called before delivery with "from_addr $| to_addr" 704038032Speter (the $| is a meta-symbol used to separate the two addresses); 704138032Speter it can give a "this sender can't send to this recipient" 704238032Speter notification. Note that this patch allows $| to stand alone 704338032Speter in rulesets. 704438032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 704538032Speter that have the name, IP address, and port number (respectively) 704638032Speter of the SMTP client (that is, the entity at the other end of 704738032Speter the connection. These can be used in (e.g.) check_rcpt to 704838032Speter verify that someone isn't trying to relay mail through your 704938032Speter host inappropriately. Be sure to use the deferred evaluation 705038032Speter form, for example $&{client_name}, to avoid having these bound 705138032Speter when sendmail reads the configuration file. 705238032Speter Add new config file rule check_relay to check the incoming connection 705338032Speter information. Like check_compat, it is passed the host name 705438032Speter and host address separated by $| and can reject connections 705538032Speter on that basis. 705638032Speter Allow IDA-style recursive function calls. Code contributed by Mark 705738032Speter Lovell and Paul Vixie. 705838032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 705938032Speter a virtual UUCP address using either a domain address or the $k 706038032Speter macro. Based on code contributed by Mark Lovell and Paul 706138032Speter Vixie. 706238032Speter Add Stanford LDAP map. Requires special libraries that are not 706338032Speter included with sendmail. Contributed by Booker C. Bense 706438032Speter <bbense@networking.stanford.edu>; contact him for support. 706538032Speter See also the src/READ_ME file. 706638032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 706738032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 706838032Speter only for debugging deep bits of code where it is important to 706938032Speter distinguish between the single-character metasymbol $+ and the 707038032Speter two characters $, +. 707138032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 707238032Speter debug_dumpstate. 707338032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 707438032Speter files that are group writable are considered "unsafe" -- that 707538032Speter is, programs and files referenced from such files are not 707638032Speter valid recipients. 707738032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 707838032Speter name that was not in DNS or was a domain-literal. Problem 707938032Speter noted by Tom May. 708038032Speter Change the introduction to error messages to more clearly delineate 708138032Speter permanent from temporary failures; if both existed in a 708238032Speter single message it could be confusing. Suggested by John 708338032Speter Beck of InReference, Inc. 708438032Speter The IngoreDot (i) option didn't work for lines that were terminated 708538032Speter with CRLF. Problem noted by Ted Stockwell of Secure 708638032Speter Computing Corporation. 708738032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 708838032Speter message headers. Problem reported by Matt Dillon of Best 708938032Speter Internet Communications. 709038032Speter Check for bogus characters in the 0200-0237 range; since these are 709138032Speter used internally, very strange errors can occur if those 709238032Speter characters appear in headers. Problem noted by Anders Gertz 709338032Speter of Lysator. 709438032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 709538032Speter recipient mailer has the F=9 flag set, and only works on 709638032Speter text/plain body types. Code contributed by Marius Olafsson 709738032Speter of the University of Iceland. 709838032Speter Special case "postmaster" name so that it is always treated as lower 709938032Speter case in alias files regardless of configuration settings; 710038032Speter this prevents some potential problems where "Postmaster" or 710138032Speter "POSTMASTER" might not match "postmaster". In most cases 710238032Speter this change is a no-op. 710338032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 710438032Speter Costales. 710538032Speter The -a map flag was ignored for dequote maps. Problem noted by 710638032Speter Bryan Costales. 710738032Speter Fix core dump when a lookup of a class "prog" map returns no 710838032Speter response. Patch from Bryan Costales. 710938032Speter Log instances where sendmail is deferring or rejecting connections 711038032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 711138032Speter Include port number in process title for network daemons. Suggested 711238032Speter by Kyle Jones of UUNET. 711338032Speter Send ``double bounces'' (errors that occur when sending an error 711438032Speter message) to the address indicated in the DoubleBounceAddress 711538032Speter option (default: postmaster). Previously they were always 711638032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 711738032Speter Add new mode, -bD, that acts like -bd in all respects except that 711838032Speter it runs in foreground. This is useful for using with a 711938032Speter wrapper that "watches" system services. Suggested by Kyle 712038032Speter Jones of UUNET. 712138032Speter Fix botch in spacing around (parenthesized) comments in addresses 712238032Speter when the comment comes before the address. Patch from 712338032Speter Motonori Nakamura of Kyoto University. 712438032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 712538032Speter that are being bounced to postmaster, rather than "Returned 712638032Speter mail". This permits the person who is postmaster more 712738032Speter easily determine what messages are to their role as 712838032Speter postmaster versus bounces to mail they actually sent. Based 712938032Speter on a suggestion by Motonori Nakamura. 713038032Speter Add new value "time" for QueueSortOrder option; this causes the queue 713138032Speter to be sorted strictly by the time of submission. Note that 713243730Speter this can cause very bad behavior over slow lines (because 713338032Speter large jobs will tend to delay small jobs) and on nodes with 713438032Speter heavy traffic (because old things in the queue for hosts that 713538032Speter are down delay processing of new jobs). Also, this does not 713638032Speter guarantee that jobs will be delivered in submission order 713738032Speter unless you also set DeliveryMode=queue. In general, it should 713838032Speter probably only be used on the command line, and only in 713938032Speter conjunction with -qRhost.domain. In fact, there are very few 714038032Speter cases where it should be used at all. Based on an 714138032Speter implementation by Motonori Nakamura. 714238032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 714338032Speter the same manner as other rulesets. Previously a temporary 714438032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 714538032Speter of Stanford University. 714638032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 714738032Speter 5yz (permanent failure) code. The next MX host will still be 714838032Speter tried if the connection cannot be opened in the first place 714938032Speter or if the MAIL command returns a 4yz (temporary failure) code. 715038032Speter (It's hard to know what to do here, since neither RFC 974 nor 715138032Speter RFC 1123 specify when to proceed to the next MX host.) 715238032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 715338032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 715438032Speter This causes map lookups that get a temporary failure (e.g., 715538032Speter name server failure) to _not_ defer the delivery of the 715638032Speter message. This should only be used if your configuration file 715738032Speter is prepared to do something sensible in this case. Based on 715838032Speter an idea by Gregory Shapiro of WPI. 715938032Speter Fix problem finding network interface addresses. Patch from 716038032Speter Motonori Nakamura. 716138032Speter Don't reject qf entries that are not owned by your effective uid if 716290792Sgshapiro you are not running set-user-ID; this makes management of 716380785Sgshapiro certain kinds of firewall setups difficult. Patch 716480785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 716538032Speter Add persistent host status. This keeps the information normally 716638032Speter maintained within a single queue run in disk files that are 716738032Speter shared between sendmail instances. The HostStatusDirectory 716838032Speter is the directory in which the information is maintained. If 716938032Speter not set, persistent host status is turned off. If not a full 717038032Speter pathname, it is relative to the queue directory. A common 717138032Speter value is ".hoststat". 717238032Speter There are also two new operation modes: 717338032Speter * -bh prints the status of hosts that have had recent 717438032Speter connections. 717538032Speter * -bH purges the host statuses. No attempt is made to save 717638032Speter recent status information. 717738032Speter This feature was originally written by Paul Vixie of Vixie 717838032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 717938032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 718038032Speter with my insistence that things fit cleanly into the V8 718138032Speter framework is gratefully appreciated. 718238032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 718338032Speter operate). Avoids letting two sendmails on the local machine 718464562Sgshapiro open connections to the same remote host at the same time. 718538032Speter This reduces load on the other machine, but can cause mail to 718638032Speter be delayed (for example, if one sendmail is delivering a huge 718738032Speter message, other sendmails won't be able to send even small 718838032Speter messages). Also, it requires another file descriptor (for the 718938032Speter lock file) per connection, so you may have to reduce 719038032Speter ConnectionCacheSize to avoid running out of per-process 719138032Speter file descriptors. Based on the persistent host status code 719238032Speter contributed by Paul Vixie and Mark Lovell. 719338032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 719438032Speter SafeFileEnvironment option is set. Problem noted by Bryan 719538032Speter Costales. 719638032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 719738032Speter file. Problem noted by Bryan Costales. 719838032Speter If a job was aborted using the interrupt signal (e.g., control-C from 719938032Speter the keyboard), on some occasions an empty df file would be 720038032Speter left around; these would collect in the queue directory. 720138032Speter Problem noted by Bryan Costales. 720238032Speter Change the makesendmail script to enhance the search for Makefiles 720338032Speter based on release number. For example, on SunOS 5.5.1, it will 720438032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 720538032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 720638032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 720738032Speter Webmasters. 720838032Speter When creating maps using "newaliases", always map the keys to lower 720938032Speter case when creating the map unless the -f flag is specified on 721038032Speter the map itself. Previously this was done based on the F=u 721138032Speter flag in the local mailer, which meant you could create aliases 721238032Speter that you could never access. Problem noted by Bob Wu of DEC. 721338032Speter When a job was read from the queue, the bits causing notification on 721438032Speter failure or delay were always set. This caused those 721538032Speter notifications to be sent even if NOTIFY=NEVER had been 721638032Speter specified. Problem noted by Steve Hubert of the University 721738032Speter of Washington, Seattle. 721838032Speter Add new configurable routine validate_connection (in conf.c). This 721938032Speter lets you decide if you are willing to accept traffic from 722038032Speter this host. If it returns FALSE, all SMTP commands will return 722138032Speter "550 Access denied". -DTCPWRAPPERS will include support for 722238032Speter TCP wrappers; you will need to add -lwrap to the link line. 722338032Speter (See src/READ_ME for details.) 722438032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 722538032Speter bounces. Some people seemed to think that this could be 722638032Speter confusing (even though it is true). Suggested by Motonori 722738032Speter Nakamura. 722838032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 722938032Speter user early in processing to avoid potential security problems. 723038032Speter However, this means that all .forward and :include: files must 723138032Speter be readable by that user, and all files to be written must be 723238032Speter writable by that user and all programs will be executed by that 723338032Speter user. It is also incompatible with the SafeFileEnvironment 723438032Speter option. In other words, it may not actually add much to 723538032Speter security. However, it should be useful on firewalls and other 723638032Speter places where users don't have accounts and the aliases file is 723738032Speter well constrained. 723838032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 723938032Speter only on the first attempt to delivery to an address. It could 724038032Speter be set to be lower than Timeout.connect on the principle that 724138032Speter the mail should go through quickly to responsive hosts; less 724238032Speter responsive hosts get to wait for the next queue run. 724338032Speter Fix a problem on Solaris that occasionally causes programs 724438032Speter (such as vacation) to hang with their standard input connected 724538032Speter to a UDP port. It also created some signal handling problems. 724638032Speter The problems turned out to be an interaction between vfork(2) 724738032Speter and some of the libraries, particularly NIS/NIS+. I am 724838032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 724938032Speter Change user class map to do the same matching that actual delivery 725038032Speter will do instead of just a /etc/passwd lookup. This adds 725138032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 725238032Speter The Timeout.* options are not safe -- they can be used to create a 725338032Speter denial-of-service attack. Problem noted by Christophe 725438032Speter Wolfhugel. 725543730Speter Don't send PostmasterCopy messages in the event of a "delayed" 725638032Speter notification. Suggested by Barry Bouwsma. 725738032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 725838032Speter option is set, since this disables VERB mode. Suggested 725938032Speter by John Hawkinson of MIT. 726038032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 726138032Speter by Motonori Nakamura of Kyoto University. 726238032Speter Only queue messages on transient .forward open failures if there 726343730Speter were no successful opens. The previous behavior caused it 726438032Speter to queue even if a "fall back" .forward was found. Problem 726538032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 726638032Speter and Computer Science (DISCS), NUS, Singapore. 726738032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 726838032Speter is bouncing because of a MIME error during 8->7 bit conversion; 726938032Speter the encapsulated message will bounce again, causing a loop. 727038032Speter Problem noted by Steve Hubert of the University of Washington. 727138032Speter Create xf (transcript) files using the TempFileMode option value 727238032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 727338032Speter National University of Singapore. 727438032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 727538032Speter detect cases where DefaultUid is set to something that the 727638032Speter system can't cope with. 727738032Speter PORTABILITY FIXES: 727838032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 727938032Speter Atlas International. 728038032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 728138032Speter <bicknell@ufp.org>. 728238032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 728338032Speter work on the first recipient of a message due to a 728438032Speter bug in the getpwent family.

Contributed by 732938032Speter Robert La Ferla of Hot Software. 733038032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 733138032Speter (where "code" is an exit status) on domains (previously 733238032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 733338032Speter Foundation. 733438032Speter CONFIG: hooks for IPv6-style domain literals. 733538032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 733638032Speter if it is undefined the AliasFile option is never set; this 733738032Speter should be transparent for most everyone. Suggested by John 733838032Speter Myers of CMU. 733938032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 734038032Speter domain listed in $=w is masqueraded. With it, only those 734138032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 734238032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 734338032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 734438032Speter hosts under those domains as well as the domain headers 734538032Speter themselves. For example, if a configuration had 734638032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 734738032Speter foo.com would be masqueraded; with it, *.foo.com would be 734838032Speter masqueraded as well. Based on an implementation by Richard 734938032Speter (Pug) Bainter of U. Texas. 735038032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 735138032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 735238032Speter Keys are user names; values are outgoing mail addresses. Yes, 735338032Speter this does overlap with the user database, and figuring out 735438032Speter just when to use which one may be tricky. Based on code 735538032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 735638032Speter from Per Hedeland of Ericsson. 735738032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 735838032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 735938032Speter Keys are either fully qualified addresses or just the host 736038032Speter part (with the @ sign). For example, a table containing: 736138032Speter info@foo.com foo-info 736238032Speter info@bar.com bar-info 736338032Speter @baz.org jane@elsewhere.net 736438032Speter would send all mail destined for info@foo.com to foo-info 736538032Speter (which is presumably an alias), mail addressed to info@bar.com 736638032Speter to bar-info, and anything addressed to anyone at baz.org will 736738032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 736838032Speter and baz.org must all be in $=w. Based on discussions with 736938032Speter a great many people. 737038032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 737138032Speter Suggested by Richard Bainter. 737238032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 737338032Speter "fax" mailer. 737438032Speter CONFIG: allow mailertable entries to resolve to local:user; this 737538032Speter passes the original user@host in to procmail-style local 737638032Speter mailers as the "detail" information to allow them to do 737738032Speter additional clever processing. From Joe Pruett of 737838032Speter Teleport Corporation. Delivery to the original user can 737938032Speter be done by specifying "local:" (with nothing after the colon). 738038032Speter CONFIG: allow any context that takes "mailer:domain" to also take 738138032Speter "mailer:user@domain" to force mailing to the given user; 738238032Speter "local:user" can also be used to do local delivery. This 738338032Speter applies on *_RELAY and in the mailertable entries. Based 738438032Speter on a suggestion by Ribert Kiessling of Easynet. 738538032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 738638032Speter limits the possible domains; this reduces the number of DNS 738738032Speter lookups required to support this feature. For example, 738838032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 738938032Speter to domains under my.site.com. Code contributed by Anthony 739038032Speter Thyssen <anthony@cit.gu.edu.au>. 739138032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 739238032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 739338032Speter of WPI. 739438032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 739538032Speter event you have to define local mailers. Suggested by 739638032Speter Gregory Shapiro of WPI. 739738032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 739838032Speter be misinterpreted as a list:...; syntax. Based on a patch by 739938032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 740038032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 740138032Speter remotely connected. The address host!user was being 740238032Speter converted to host!user@thishost instead of host!user@uurelay. 740338032Speter Problem noted by William Gianopoulos of Raytheon Company. 740438032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 740538032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 740638032Speter "User has moved"; the former wording was confusing if the 740738032Speter new address is still on the local host. Based on a suggestion 740838032Speter by Andreas Luik. 740938032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 741038032Speter However, the class is not pre-initialized to contain root. 741138032Speter Suggested by Gregory Neil Shapiro. 741238032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 741338032Speter Wolfhugel. 741438032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 741538032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 741638032Speter well: this produces a slightly different mailbox format (no 741738032Speter Content-Length: headers), file ownerships and modes are 741838032Speter different (not owned by group mail; mode 600 instead of 660), 741938032Speter and the local mailer flags will have to be tweaked (make them 742038032Speter match bsd4.4) in order to use this mailer. Patches from Paul 742138032Speter Hammann of the Missouri Research and Education Network. 742238032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 742338032Speter was a delivery error, such as if the ownership on the file 742438032Speter was wrong or the mode changed between the initial stat and 742538032Speter the open. Problem reported by William Colburn of the New 742638032Speter Mexico Institute of Mining and Technology. 742738032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 742838032Speter Costales. 742938032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 743038032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 743138032Speter honored. Fix from Michael Scott Shappe. 743238032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 743338032Speter NEW FILES: 743438032Speter src/Makefiles/Makefile.AIX.2 743538032Speter src/Makefiles/Makefile.IRIX.6.2 743638032Speter src/Makefiles/Makefile.maxion 743738032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 743838032Speter src/Makefiles/Makefile.SCO.5.x 743938032Speter src/Makefiles/Makefile.UXPDSV20 744038032Speter mailstats/mailstats.8 744138032Speter praliases/praliases.8 744238032Speter cf/cf/generic-nextstep3.3.mc 744338032Speter cf/feature/genericstable.m4 744438032Speter cf/feature/limited_masquerade.m4 744538032Speter cf/feature/masquerade_entire_domain.m4 744638032Speter cf/feature/virtusertable.m4 744738032Speter cf/ostype/aix2.m4 744838032Speter cf/ostype/altos.m4 744938032Speter cf/ostype/maxion.m4 745038032Speter cf/ostype/solaris2.ml.m4 745138032Speter cf/ostype/uxpds.m4 745238032Speter contrib/re-mqueue.pl 745338032Speter DELETED FILES: 745438032Speter src/Makefiles/Makefile.Solaris 745538032Speter contrib/xla/README 745638032Speter contrib/xla/xla.c 745738032Speter RENAMED FILES: 745838032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 745938032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 746038032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 746138032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 746238032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 746338032Speter 746464562Sgshapiro8.7.6/8.7.3 1996/09/17 746538032Speter SECURITY: It is possible to force getpwuid to fail when writing the 746638032Speter queue file, causing sendmail to fall back to running programs 746738032Speter as the default user. This is not exploitable from off-site. 746838032Speter Workarounds include using a unique user for the DefaultUser 746938032Speter (old u & g options) and using smrsh as the local shell. 747038032Speter SECURITY: fix some buffer overruns; in at least one case this allows 747138032Speter a local user to get root. This is not known to be exploitable 747238032Speter from off-site. The workaround is to disable chfn(1) commands. 747338032Speter 747464562Sgshapiro8.7.5/8.7.3 1996/03/04 747538032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 747638032Speter in some case cause connections to hang or messages to have 747738032Speter extra spaces in odd places. Patch from Eric Wassenaar; 747838032Speter reports from Eric Hall of Chiron Corporation, Stephen 747938032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 748038032Speter and others. 748138032Speter 748264562Sgshapiro8.7.4/8.7.3 1996/02/18 748338032Speter SECURITY: In some cases it was still possible for an attacker to 748438032Speter insert newlines into a queue file, thus allowing access to 748538032Speter any user (except root). 748638032Speter CONFIG: no changes -- it is not a bug that the configuration 748738032Speter version number is unchanged. 748838032Speter 748964562Sgshapiro8.7.3/8.7.3 1995/12/03 749038032Speter Fix botch in name server timeout in RCPT code; this problem caused 749138032Speter two responses in SMTP, which breaks things horribly. Fix 749238032Speter from Gregory Neil Shapiro of WPI. 749338032Speter Verify that L= value on M lines cannot be negative, which could cause 749438032Speter negative array subscripting. Not a security problem since 749538032Speter this has to be in the config file, but it could have caused 749638032Speter core dumps. Pointed out by Bryan Costales. 749738032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 749838032Speter Costales. 749938032Speter PORTABILITY FIXES: 750038032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 750138032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 750238032Speter order. Tweak it to work properly. Based on fixes 750338032Speter from Fletcher Mattox of UTexas and Betty Lee of 750438032Speter Stanford University. 750538032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 750638032Speter Deficiency pointed out by Bryan Costales of ICSI. 750738032Speter 750864562Sgshapiro8.7.2/8.7.2 1995/11/19 750938032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 751038032Speter OperatorChars, and UnixFromLine options. They were not 751138032Speter properly repaired in 8.7.1. 751238032Speter Completely delete the Bcc: header if and only if there are other 751338032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 751438032Speter last being a historic botch, of course). If Bcc: is the 751538032Speter only recipient header in the message, its value is tossed, 751643730Speter but the header name is kept. The old behavior (always keep 751738032Speter the header name and toss the value) allowed primary recipients 751838032Speter to see that a Bcc: went to _someone_. 751938032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 752038032Speter sender to <address> using -f'' syslog messages. Suggested 752138032Speter by Kari Hurtta. 752238032Speter If a sequence or switch map lookup entry gets a tempfail but then 752338032Speter continues on to another map type, but the name is not found, 752438032Speter return a temporary failure from the sequence or switch map. 752538032Speter For example, if hosts search ``dns files'' and DNS fails 752638032Speter with a tempfail, the hosts map will go on and search files, 752738032Speter but if it fails the whole thing should be a tempfail, not 752838032Speter a permanent (host unknown) failure, even though that is the 752938032Speter failure in the hosts.files map. This error caused hard 753038032Speter bounces when it should have requeued. 753138032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 753290792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 753338032Speter working properly due to excessive paranoia. Pointed out by 753438032Speter John Hawkinson of Panix. 753538032Speter An SMTP RCPT command referencing a host that gave a nameserver 753638032Speter timeout would return a 451 command (8.6 accepted it and 753743730Speter queued it locally). Revert to the 8.6 behavior in order 753838032Speter to simplify queue management for clustered systems. Suggested 753938032Speter by Gregory Neil Shapiro of WPI. The same problem could break 754038032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 754138032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 754238032Speter Infobiogen. 754338032Speter Fix possible buffer overflow in munchstring(). This was not a security 754438032Speter problem because you couldn't specify any argument to this 754538032Speter without first giving up root privileges, but it is still a 754638032Speter good idea to avoid future problems. Problem noted by John 754738032Speter Hawkinson and Sam Hartman of MIT. 754838032Speter ``452 Out of disk space for temp file'' messages weren't being 754938032Speter printed. Fix from David Perlin of Nanosoft. 755043730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 755138032Speter is not set, since this is required to get the actual DSNs 755238032Speter created. Problem pointed out by John Gardiner Myers of CMU. 755338032Speter Log permission problems that cause .forward and :include: files to 755438032Speter be untrusted or ignored on log level 12 and higher. Suggested 755538032Speter by Randy Martin of Clemson University. 755638032Speter Allow user ids in U= clauses of M lines to have hyphens and 755738032Speter underscores. 755838032Speter Fix overcounting of recipients -- only happened when sending to an 755938032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 756038032Speter of Systems and Computer Technology Corporation. 756138032Speter If a message is sent to an address that fails, the error message that 756238032Speter is returned could show some extraneous "success" information 756338032Speter included even if the user did not request success notification, 756438032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 756538032Speter Config files that had no AliasFile definition were defaulting to 756638032Speter using /etc/aliases; this caused problems with nullclient 756738032Speter configurations. Change it back to the 8.6 semantics of 756838032Speter having no local alias file unless it is declared. Problem 756938032Speter noted by Charles Karney of Princeton University. 757038032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 757138032Speter Costales of ICSI. 757238032Speter Map lookups of class "userdb" maps were always case sensitive; they 757338032Speter should be controlled by the -f flag like other maps. Pointed 757438032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 757538032Speter Fix problem that caused some addresses to be passed through ruleset 5 757638032Speter even when they were tagged as "sticky" by prefixing the 757738032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 757838032Speter Technological University. 757938032Speter When converting a message to Quoted-Printable, prevent any lines with 758038032Speter dots alone on a line by themselves. This is because of the 758138032Speter preponderance of broken mailers that still get this wrong. 758238032Speter Code contributed by Per Hedeland of Ericsson. 758338032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 758438032Speter out by Bjart Kvarme of USIT/UiO (Norway). 758538032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 758638032Speter Requested by Allan Johannesen. 758738032Speter Delete check for text format of alias files -- it should be legal 758838032Speter to have the database format of the alias files without the 758938032Speter text version. Problem pointed out by Joe Rhett of Navigist, 759038032Speter Inc. 759138032Speter If "Ot" was specified with no value, the TZ variable was not properly 759238032Speter imported from the environment. Pointed out by Frank Crawford 759338032Speter <frank@ansto.gov.au>. 759438032Speter Some architectures core dumped on "program" maps that didn't have 759538032Speter extra arguments. Patch from Booker C. Bense of Stanford 759638032Speter University. 759738032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 759838032Speter the parent should do this. Fix from Brian Coan of the 759938032Speter Association for Progressive Communications. 760038032Speter If MinQueueAge was set and a message was considered but not run 760138032Speter during a queue run and the Timeout.queuereturn interval was 760238032Speter reached, a "timed out" error message would be returned that 760338032Speter didn't include the failed address (and claimed to be a warning 760438032Speter even though it was fatal). The fix is to not return such 760538032Speter messages until they are actually tried, i.e., in the next 760638032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 760738032Speter SINTEF RUNIT, Oslo. 760838032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 760938032Speter that have the hes_getmailhost() routine.

Bug 765638032Speter pointed out by John Hawkinson of MIT. 765738032Speter Fix strange case of an executable called by a program map that 765838032Speter returns a value but also a non-zero exit status; this 765938032Speter would give contradictory results in the higher level; in 766038032Speter particular, the default clause in the map lookup would be 766138032Speter ignored. Change to ignore the value if the program returns 766238032Speter non-zero exit status. From Tom Moore of AT&T GIS. 766338032Speter Shorten parameters passed to syslog() in some contexts to avoid a 766438032Speter bug in many vendors' implementations of that routine. Although 766538032Speter this isn't really a bug in sendmail per se, and my solution 766638032Speter has to assume that syslog() has at least a 1K buffer size 766738032Speter internally (I know some vendors have shortened this 766838032Speter dramatically -- they're on their own), sendmail is a popular 766938032Speter target. Also, limit the size of %s arguments in sprintf. 767038032Speter These both have possible security implications. Solutions 767138032Speter suggested by Casper Dik of Sun's Network Security Group 767238032Speter (Holland), Mark Seiden, and others. 767338032Speter Fix a problem that might cause a non-standard -B (body type) 767438032Speter parameter to be passed to the next server with undefined 767538032Speter results. This could have security implications. 767638032Speter If a filesystem was at > 100% utilization, the freediskspace() 767738032Speter routine incorrectly returned an error rather than zero. 767838032Speter Problem noted by G. Paul Ziemba of Alantec. 767938032Speter Change MX sort order so that local hostnames (those in $=w) always 768038032Speter sort first within a given preference. This forces the bestmx 768138032Speter map to always return the local host first, if it is included 768238032Speter in the list of highest priority MX records. From K. Robert 768338032Speter Elz. 768438032Speter Avoid some possible null pointer dereferences. Fixes from Randy 768538032Speter Martin <WOLF@CLEMSON.EDU> 768638032Speter When sendmail starts up on systems that have no fully qualified 768738032Speter domain name (FQDN) anywhere in the first matching host map 768838032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 768938032Speter sendmail would sleep to try to find a FQDN, which it really 769038032Speter really needs. This has been changed to fall through to the 769138032Speter next map type if it can't find a FQDN -- i.e., if the hosts 769238032Speter file doesn't have a FQDN, it will try dns even though the 769338032Speter short name was found in /etc/hosts. This is probably a crock, 769438032Speter but many people have hosts files without FQDNs. Remember: 769538032Speter domain names are your friends. 769638032Speter Log a high-priority message if you can't find your FQDN during startup. 769738032Speter Suggested by Simon Barnes of Schlumberger Limited. 769838032Speter When using Hesiod, initialize it early to improve error reporting. 769938032Speter Patch from Don Lewis of Silicon Systems, Inc. 770038032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 770138032Speter connection timeout in the kernel. Add a new "connect" timeout 770238032Speter to limit this time. Defaults to zero (use whatever the 770338032Speter kernel provides). Based on code contributed by J.R. Oldroyd 770438032Speter of TerraNet. 770538032Speter Under some circumstances, a failed message would not be properly 770638032Speter removed from the queue, causing tons of bogus error messages. 770738032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 770838032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 770938032Speter of WPI. 771038032Speter PORTABILITY FIXES: 771138032Speter On IRIX 5.x, there was an inconsistency in the setting 771238032Speter of sendmail.st location. Change the Makefile to 771338032Speter install it in /var/sendmail.st to match the OSTYPE 771438032Speter file and SGI standards.

Suggested by Per Hedeland of Ericsson. 772838032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 772938032Speter otherwise the F=S causes the From_ line to imply that root is 773038032Speter the sender. Problem pointed out by Claude Scarpelli of 773138032Speter Infobiogen (France). 773238032Speter NEW FILES: 773338032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 773438032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 773538032Speter src/Makefiles/Makefile.UXPDS 773638032Speter 773764562Sgshapiro8.7/8.7 1995/09/16 773838032Speter Fix a problem that could cause sendmail to run out of file 773938032Speter descriptors due to a trashed data structure after a 774038032Speter vfork.

This was used "safely" in the sense 774638032Speter that it only did a stat, but it would have set the 774738032Speter map modification time improperly. Problem pointed out 774838032Speter by Roy Mongiovi of Georgia Tech. 774938032Speter Clean up the Subject: line on warning messages and return 775038032Speter receipts so that they don't say "Returned mail:"; this 775138032Speter can be confusing. 775238032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 775338032Speter useful enough to make it worthwhile printing on "-d". 775438032Speter Avoid logging alias statistics every time you read the alias 775538032Speter file on systems with no database method compiled in. 775638032Speter If you have a name with a trailing dot, and you try looking it 775738032Speter up using gethostbyname without the dot (for /etc/hosts 775838032Speter compatibility), be sure to turn off RES_DEFNAMES and 775938032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 776038032Speter Problem noted by Charles Amos of the University of 776138032Speter Maryland. 776238032Speter Don't do timeouts in collect if you are not running SMTP. 776338032Speter There is nothing that says you can't have a long 776438032Speter running program piped into sendmail (possibly via 776538032Speter /bin/mail, which just execs sendmail). Problem reported 776638032Speter by Don "Truck" Lewis of Silicon Systems. 776738032Speter Try gethostbyname() even if the DNS lookup fails iff option I 776838032Speter is not set. This allows you to have hosts listed in 776938032Speter NIS or /etc/hosts that are not known to DNS. It's normally 777038032Speter a bad idea, but can be useful on firewall machines. This 777138032Speter should really be broken out on a separate flag, I suppose. 777238032Speter Avoid compile warnings against BIND 4.9.3, which uses function 777338032Speter prototypes.

From Kyle Jones of UUNET. 777838032Speter SECURITY: avoid denial-of-service attacks possible by destroying 777938032Speter the alias database file by setting resource limits low. 778038032Speter This involves adding two new compile-time options: 778138032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 778238032Speter available) and HASULIMIT (indicating that ulimit(2) support 778338032Speter is available -- the Release 3 form is used). The former 778438032Speter is assumed on BSD-based systems, the latter on System 778538032Speter V-based systems. Attack noted by Phil Brandenberger of 778638032Speter Swarthmore University. 778738032Speter New syntaxes in test (-bt) mode: 778838032Speter ``.Dmvalue'' will define macro "m" to "value". 778938032Speter ``.Ccvalue'' will add "value" to class "c". 779038032Speter ``=Sruleset'' will dump the contents of the indicated 779138032Speter ruleset. 779238032Speter ``=M'' will display the known mailers. 779338032Speter ``-ddebug-spec'' is equivalent to the command-line 779438032Speter -d debug flag. 779538032Speter ``$m'' will print the value of macro $m. 779638032Speter ``$=c'' will print the contents of class $=c. 779738032Speter ``/mx host'' returns the MX records for ``host''. 779838032Speter ``/parse address'' will parse address, returning the value of 779938032Speter crackaddr (essentially, the comment information) 780038032Speter and the parsed address. 780138032Speter ``/try mailer address'' will rewrite address into the form 780238032Speter it will have when presented to the indicated mailer. 780338032Speter ``/tryflags flags'' will set flags used by parsing. The 780438032Speter flags can be `H' for header or `E' for envelope, 780538032Speter and `S' for sender or `R' for recipient. These 780638032Speter can be combined, so `HR' sets flags for header 780738032Speter recipients. 780838032Speter ``/canon hostname'' will try to canonify hostname and 780938032Speter return the result. 781038032Speter ``/map mapname key'' will look up `key' in the indicated 781138032Speter `mapname' and return the result. 781238032Speter Somewhat better handling of UNIX-domain socket addresses -- it 781338032Speter should show the pathname rather than hex bytes. 781438032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 781538032Speter the header for envelope sender information and uses 781638032Speter CR-LF as message terminators. It was thought to be 781738032Speter obsolete (used only for Arpanet NCP protocols), but it 781838032Speter turns out that the UK ``Grey Book'' protocols require 781938032Speter that functionality. 782038032Speter Fix a fix in previous release -- if gethostname and gethostbyname 782138032Speter return a name without dots, and if an attempt to canonify 782238032Speter that name fails, wait one minute and try again. This can 782338032Speter result in an extra 60 second delay on startup if your system 782438032Speter hostname (as returned by hostname(1)) has no dot and no names 782538032Speter listed in /etc/hosts or your NIS map have a dot. 782638032Speter Check for proper domain name on HELO and EHLO commands per 782738032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 782838032Speter of Michigan Technological University. 782938032Speter Relax chownsafe rules slightly -- old version said that if you 783038032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 783138032Speter if fpathconf returned EINVAL or ENOSYS), assume that 783238032Speter chown is not safe. The new version falls back to whether 783338032Speter you are on a BSD system or not. This is important for 783438032Speter SunOS, which apparently always returns one of those 783538032Speter error codes. This impacts whether you can mail to files 783638032Speter or not. 783738032Speter Syntax errors such as unbalanced parentheses in the configuration 783838032Speter file could be omitted if you had "Oem" prior to the 783938032Speter syntax error in the config file. Change to always print 784038032Speter the error message. It was especially weird because it 784138032Speter would cause a "warning" message to be sent to the Postmaster 784238032Speter for every message sent (but with no transcript). Problem 784338032Speter noted by Gregory Paris of Motorola. 784438032Speter Rewrite collect and putbody to handle full 8-bit data, including 784538032Speter zero bytes. These changes are internally extensive, but 784638032Speter should have minimal impact on external function. 784738032Speter Allow full words for option names -- if the option letter is 784838032Speter (apparently) a space, then take the word following -- e.g., 784938032Speter O MatchGECOS=TRUE 785038032Speter The full list of old and new names is as follows: 785138032Speter 7 SevenBitInput 785238032Speter 8 EightBitMode 785338032Speter A AliasFile 785438032Speter a AliasWait 785538032Speter B BlankSub 785638032Speter b MinFreeBlocks/MaxMessageSize 785738032Speter C CheckpointInterval 785838032Speter c HoldExpensive 785938032Speter D AutoRebuildAliases 786038032Speter d DeliveryMode 786138032Speter E ErrorHeader 786238032Speter e ErrorMode 786338032Speter f SaveFromLine 786438032Speter F TempFileMode 786538032Speter G MatchGECOS 786638032Speter H HelpFile 786738032Speter h MaxHopCount 786838032Speter i IgnoreDots 786938032Speter I ResolverOptions 787038032Speter J ForwardPath 787138032Speter j SendMimeErrors 787238032Speter k ConnectionCacheSize 787338032Speter K ConnectionCacheTimeout 787438032Speter L LogLevel 787538032Speter l UseErrorsTo 787638032Speter m MeToo 787738032Speter n CheckAliases 787838032Speter O DaemonPortOptions 787938032Speter o OldStyleHeaders 788038032Speter P PostmasterCopy 788138032Speter p PrivacyOptions 788238032Speter Q QueueDirectory 788338032Speter q QueueFactor 788438032Speter R DontPruneRoutes 788538032Speter r, T Timeout 788638032Speter S StatusFile 788738032Speter s SuperSafe 788838032Speter t TimeZoneSpec 788938032Speter u DefaultUser 789038032Speter U UserDatabaseSpec 789143730Speter V FallbackMXHost 789238032Speter v Verbose 789338032Speter w TryNullMXList 789438032Speter x QueueLA 789538032Speter X RefuseLA 789638032Speter Y ForkEachJob 789738032Speter y RecipientFactor 789838032Speter z ClassFactor 789938032Speter Z RetryFactor 790038032Speter The old macros that passed information into sendmail have 790138032Speter been changed to options; those correspondences are: 790238032Speter $e SmtpGreetingMessage 790338032Speter $l UnixFromLine 790438032Speter $o OperatorChars 790538032Speter $q (deleted -- not necessary) 790638032Speter To avoid possible problems with an older sendmail, 790738032Speter configuration level 6 is accepted by this version of 790838032Speter sendmail; any config file using the new names should 790938032Speter specify "V6" in the configuration. 791038032Speter Change address parsing to properly note that a phrase before a 791138032Speter colon and a trailing semicolon are essentially the same 791238032Speter as text outside of angle brackets (i.e., sendmail should 791338032Speter treat them as comments). This is to handle the 791438032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 791538032Speter assume that ``group name:'' is a comment on the first 791638032Speter address and the ``;'' is a comment on the last address). 791738032Speter This requires config file support to get right. It does 791838032Speter understand that :: is NOT this syntax, and can be turned 791938032Speter off completely by setting the ColonOkInAddresses option. 792038032Speter Level 6 config files added with new mailer flags: 792138032Speter A Addresses are aliasable. 792238032Speter i Do udb rewriting on envelope as well as header 792338032Speter sender lines. Applies to the from address mailer 792438032Speter flags rather than the recipient mailer flags. 792538032Speter j Do udb rewriting on header recipient addresses. 792638032Speter Applies to the sender mailer flags rather than the 792738032Speter recipient mailer flags. 792838032Speter k Disable check for loops when doing HELO command. 792938032Speter o Always run as the mail recipient, even on local 793038032Speter delivery. 793138032Speter w Check for an /etc/passwd entry for this user. 793238032Speter 5 Pass addresses through ruleset 5. 793338032Speter : Check for :include: on this address. 793438032Speter | Check for |program on this address. 793538032Speter / Check for /file on this address. 793638032Speter @ Look up sender header addresses in the user 793738032Speter database. Applies to the mailer flags for the 793838032Speter mailer corresponding to the envelope sender 793938032Speter address, rather than to recipient mailer flags. 794038032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 794138032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 794238032Speter mailers, and the ColonOkInAddresses option. 794338032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 794438032Speter John Beck of Hewlett-Packard, who generously contributed 794538032Speter their implementation to me, which I then didn't use (see 794638032Speter mime.c for an explanation of why). This adds the 794738032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 794838032Speter to control handling of 8-bit data. These have to cope with 794938032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 795038032Speter 8-bit data that is entered without declaring it as 8-bit 795138032Speter MIME -- technically this is illegal according to the 795238032Speter specs) and labelled 8-bit data (that is, it was declared 795338032Speter as 8BITMIME in the ESMTP session or by using the 795438032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 795538032Speter set then 8-bit data is sent to non-8BITMIME machines 795638032Speter instead of converting to 7 bit (essentially using 795738032Speter just-send-8 semantics). The values for EightBitMode are: 795838032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 795938032Speter any necessary conversion of 8BITMIME to 7BIT 796038032Speter (essentially, the full MIME option). 796138032Speter p pass unlabelled 8-bit input, but convert labelled 796238032Speter 8BITMIME input to 7BIT as required (default). 796338032Speter s strict adherence: reject unlabelled 8-bit input, 796438032Speter convert 8BITMIME to 7BIT as required. The F=8 796538032Speter flag is ignored. 796638032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 796738032Speter the setting of F=8. 796838032Speter Add new internal class 'n', which is the set of MIME Content-Types 796938032Speter which can not be 8 to 7 bit encoded because of other 797038032Speter considerations. Types "multipart/*" and "message/*" are 797138032Speter never directly encoded (although their components can be). 797238032Speter Add new internal class 's', which is the set of subtypes of the 797338032Speter MIME message/* content type that can be treated as though 797438032Speter they are an RFC822 message. It is predefined to have 797538032Speter "rfc822". Suggested By Kari Hurtta. 797638032Speter Add new internal class 'e'. This is the set of MIME 797738032Speter Content-Transfer-Encodings that can be converted to 797838032Speter a seven bit format (Quoted-Printable or Base64). It is 797938032Speter preinitialized to contain "7bit", "8bit", and "binary". 798038032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 798138032Speter short name) to set the default character set to use in the 798238032Speter Content-Type: header when doing encoding of an 8-bit message 798338032Speter which isn't marked as MIME into MIME format. If the C= 798438032Speter parameter is set on the Envelope From address, use that as 798538032Speter the default encoding; else use the DefaultCharSet option. 798638032Speter If neither is set, it defaults to "unknown-8bit" as 798738032Speter suggested by RFC 1428 section 3. 798838032Speter Allow ``U=user:group'' field in mailer definition to set a default 798938032Speter user and group that a mailer will be executed as. This 799038032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 799138032Speter also set, it is the uid/gid that will always be used (that 799238032Speter is, the controlling address is ignored). The values may be 799338032Speter numeric or symbolic; if only a symbolic user is given (no 799438032Speter group) that user's default group in the passwd file is used 799538032Speter as the group. Based on code donated by Chip Rosenthal of 799638032Speter Unicom. 799738032Speter Allow `u' option to also accept user:group as a value, in the same 799838032Speter fashion as the U= mailer option. 799938032Speter Add the symbolic time zone name in the Arpanet format dates (as 800038032Speter a comment). This adds a new compile-time configuration 800138032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 800238032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 800338032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 800438032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 800538032Speter timezone()), or TZ_NONE (don't include the comment). Code 800638032Speter from Chip Rosenthal. 800738032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 800838032Speter For example, 800938032Speter O Timeout.helo = 2m 801038032Speter There are also two new suboptions "queuereturn" and 801138032Speter "queuewarn"; these subsume the old T option. Thus, to 801238032Speter set them both the preferred new syntax is 801338032Speter O Timeout.queuereturn = 5d 801438032Speter O Timeout.queuewarn = 4h 801538032Speter Sort queue by host name instead of by message priority if the 801638032Speter QueueSortOrder option (no short name) is set is set to 801738032Speter ``host''. This makes better use of the connection cache, 801838032Speter but may delay more ``interactive'' messages behind large 801938032Speter backlogs under some circumstances. This is probably a 802038032Speter good option if you have high speed links or don't do lots 802138032Speter of ``batch'' messages, but less good if you are using 802238032Speter something like PPP on a 14.4 modem. Based on code 802338032Speter contributed by Roy Mongiovi of Georgia Tech (my main 802438032Speter contribution was to make it configurable). 802538032Speter Save i-number of df file in qf file to simplify rebuilding of queue 802638032Speter after disastrous disk crash. Suggested by Kyle Jones of 802738032Speter UUNET; closely based on code from KJS DECWRL code written 802838032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 802938032Speter are NOT back compatible with 8.6 -- that is, you can convert 803038032Speter from 8.6 to 8.7, but not the other direction. 803138032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 803238032Speter route-addrs in envelopes; this is because in some cases 803338032Speter they can be sent to the shell, which interprets them as 803438032Speter I/O redirection. 803538032Speter Don't include error file (option E) with return-receipts; this 803638032Speter can be confusing. 803738032Speter Don't send "Warning: cannot send" messages to owner-* or 803838032Speter *-request addresses. Suggested by Christophe Wolfhugel 803938032Speter of the Institut Pasteur, Paris. 804038032Speter Allow -O command line flag to set long form options. 804138032Speter Add "MinQueueAge" option to set the minimum time between attempts 804238032Speter to run the queue. For example, if the queue interval 804338032Speter (-q value) is five minutes, but the minimum queue age 804438032Speter is fifteen minutes, jobs won't be tried more often than 804538032Speter once every fifteen minutes. This can be used to give 804638032Speter you more responsiveness if your delivery mode is set to 804738032Speter queue-only. 804838032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 804938032Speter :include: and .forward files. 805038032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 805138032Speter key field name, the value field name, and the field 805238032Speter delimiter. The field delimiter can be a single character 805338032Speter or the sequence "\t" or "\n" for tab or newline. 805438032Speter These are for use by NIS+ and similar access methods. 805538032Speter Change maps to always strip quotes before lookups; the -q flag 805643730Speter turns off this behavior. Suggested by Motonori Nakamura. 805738032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 805838032Speter key and value field names respectively. Code donated by 805938032Speter Sun Microsystems. 806038032Speter Add "hesiod" map class. The "file name" is used as the 806138032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 806238032Speter first value found for the match. Code donated by Scott 806338032Speter Hutton of Indiana University. 806438032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 806538032Speter specify the name of the property that is searched as the 806638032Speter key and a -v flag to specify the name of the property that 806738032Speter is returned as the value (defaults to "members"). The 806838032Speter default map is "/aliases". Some code based on code 806938032Speter contributed by Robert La Ferla of Hot Software. 807038032Speter Add "text" map class. This does slow, linear searches through 807138032Speter text files. The -z flag specifies a column delimiter 807238032Speter (defaults to any sequence of white space), the -k flag 807338032Speter sets the key column number, and the -v flag sets the 807438032Speter value column number. Lines beginning with `#' are treated 807538032Speter as comments. 807638032Speter Add "program" map class to execute arbitrary programs. The search 807738032Speter key is presented as the last argument; the output is one 807838032Speter line read from the programs standard output. Exit statuses 807938032Speter are from sysexits.h. 808038032Speter Add "sequence" map class -- searches maps in sequence until it 808138032Speter finds a match. For example, the declarations: 808238032Speter Kmap1 ... 808338032Speter Kmap2 ... 808438032Speter Kmapseq sequence map1 map2 808538032Speter defines a map "mapseq" that first searches map1; if the 808638032Speter value is found it is returned immediately, otherwise 808738032Speter map2 is searched and the value returned. 808838032Speter Add "switch" map class. This is much like "sequence" except that 808938032Speter the ordering is fetched from an external file, usually 809038032Speter the system service switch. The parameter is the name of 809138032Speter the service to switch on, and the maps that it will use 809238032Speter are the name of the switch map followed by ".service_type". 809338032Speter For example, if the declaration of the map is 809438032Speter Ksample switch hosts 809538032Speter and the system service switch specifies that hosts are 809638032Speter looked up using dns and nis in that order, then this is 809738032Speter equivalent to 809838032Speter Ksample sequence sample.dns sample.nis 809938032Speter The subordinate maps (sample.*) must already be defined. 810038032Speter Add "user" map class -- looks up users using getpwnam. Takes a 810138032Speter "-v field" flag on the definition that tells what passwd 810238032Speter entry to return -- legal values are name, passwd, uid, gid, 810338032Speter gecos, dir, and shell. Generally expected to be used with 810438032Speter the -m (matchonly) flag. 810538032Speter Add "bestmx" map class -- returns the best MX value for the host 810638032Speter listed as the value. If there are several "best" MX records 810738032Speter for this host, one will be chosen at random. 810838032Speter Add "userdb" map class -- looks up entries in the user database. 810938032Speter The "file name" is actually the tag that will be used, 811038032Speter typically "mailname". If there are multiple entries 811138032Speter matching the name, the one chosen is undefined. 811238032Speter Add multiple queue timeouts (both return and warning). These are 811338032Speter set by the Precedence: or Priority: header fields to one of 811438032Speter three values. If a Priority: is set and has value "normal", 811564562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 811638032Speter used. If no priority is set, the Precedence: is consulted; 811738032Speter if negative, non-urgent timeouts are used; if greater than 811838032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 811938032Speter are used. The timeouts are set by setting the six timeouts 812038032Speter queue{warn,return}.{urgent,normal,non-urgent}. 812138032Speter Fix problem when a mail address is resolved to a $#error mailer 812238032Speter with a temporary failure indication; it works in SMTP, 812338032Speter but when delivering locally the mail is silently discarded. 812438032Speter This patch, from Kyle Jones of UUNET, bounces it instead 812538032Speter of queueing it (queueing is very hard). 812638032Speter When using /etc/hosts or NIS-style lookups, don't assume that 812738032Speter the first name in the list is the best one -- instead, 812838032Speter search for the first one with a dot. For example, if 812938032Speter an /etc/hosts entry reads 813038032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 813138032Speter this change will use the second name as the canonical 813238032Speter machine name instead of the initial, unqualified name. 813338032Speter Change dequote map to replace spaces in quoted text with a value 813438032Speter indicated by the -s flag on the dequote map definition. 813538032Speter For example, ``Mdequote dequote -s_'' will change 813638032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 813738032Speter quoted (because of the space character). Suggested by Dan 813838032Speter Oscarsson for use in X.400 addresses. 813938032Speter Implement long macro names as ${name}; long class names can 814038032Speter be similarly referenced as $={name} and $~{name}. 814138032Speter Definitions are (e.g.) ``D{name}value''. Names that have 814238032Speter a leading lower case letter or punctuation characters are 814338032Speter reserved for internal use by sendmail; i.e., config files 814438032Speter should use names that begin with a capital letter. Based 814538032Speter on code contributed by Dan Oscarsson. 814638032Speter Fix core dump if getgrgid returns a null group list (as opposed 814738032Speter to an empty group list, that is, a pointer to a list 814838032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 814938032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 815038032Speter failed, it called syserr which called newstr which called 815138032Speter xalloc.... The newstr is now avoided for "panic" messages. 815238032Speter Reported by Stuart Kemp of James Cook University. 815338032Speter Improve connection cache timeouts; previously, they were not even 815438032Speter checked if you were delivering to anything other than an 815538032Speter IPC-connected host, so a series of (say) local mail 815638032Speter deliveries could cause cached connections to be open 815738032Speter much longer than the specified timeout. 815838032Speter If an incoming message exceeds the maximum message size, stop 815938032Speter writing the incoming bytes to the queue data file, since 816038032Speter this can fill your mqueue partition -- this is a possible 816138032Speter denial-of-service attack. 816238032Speter Don't reject all numeric local user names unless HESIOD is 816338032Speter defined. It turns out that Posix allows all-numeric 816438032Speter user names. Fix from Tony Sanders of BSDI. 816538032Speter Add service switch support. If the local OS has a service 816638032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 816738032Speter on DEC systems) that will be used; otherwise, it falls back 816838032Speter to using a local mechanism based on the ServiceSwitchFile 816938032Speter option (default: /etc/service.switch). For example, if the 817038032Speter service switch lists "files" and "nis" for the aliases 817138032Speter service, that will be the default lookup order. the "files" 817238032Speter ("local" on DEC) service type expands to any alias files 817338032Speter you listed in the configuration file, even if they aren't 817438032Speter actually file lookups. 817538032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 817638032Speter variable which tells whether or not DNS should be considered 817738032Speter canonical. This is now determined based on whether or not 817838032Speter "dns" is in the service list for "hosts". 817938032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 818038032Speter Status Notifications). DSN notifications override 818138032Speter Return-Receipt-To: headers, which are bogus anyhow -- 818238032Speter support for them has been removed. 818338032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 818438032Speter definitions to define the types used in DSN returns for 818538032Speter MTA names, addresses, and diagnostics respectively. 818638032Speter Extend heuristic to force running in ESMTP mode to look for the 818738032Speter five-character string "ESMTP" anywhere in the 220 greeting 818838032Speter message (not just the second line). This is to provide 818938032Speter better compatibility with other ESMTP servers. 819038032Speter Print sequence number of job when running the queue so you can 819138032Speter easily see how much progress you have made. Suggested 819238032Speter by Peter Wemm of DIALix. 819338032Speter Map newlines to spaces in logged message-ids; some versions of 819438032Speter syslog truncate the rest of the line after newlines. 819538032Speter Suggested by Fletcher Mattox of U. Texas. 819638032Speter Move up forking for job runs so that if a message is split into 819738032Speter multiple envelopes you don't get "fork storms" -- this 819838032Speter also improves the connection cache utilization. 819938032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 820038032Speter the purposes of refusing to send error returns. Suggested 820138032Speter by Motonori Nakamura of Ritsumeikan University. 820238032Speter Relax rules on when a file can be written when referenced from 820338032Speter the aliases file: use the default uid/gid instead of the 820438032Speter real uid/gid. This allows you to create a file owned by 820538032Speter and writable only by the default uid/gid that will work 820690792Sgshapiro all the time (without having the set-user-ID bit set). Change 820738032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 820838032Speter Microsystems. 820938032Speter Add "DialDelay" option (no short name) to provide an "extra" 821038032Speter delay for dial on demand systems. If this is non-zero 821138032Speter and a connect fails, sendmail will wait this long and 821238032Speter then try again. If it takes longer than the kernel 821338032Speter timeout interval to establish the connection, this 821438032Speter option can give the network software time to establish 821538032Speter the link. The default units are seconds. 821638032Speter Move logging of sender information to be as early as possible; 821738032Speter previously, it could be delayed a while for SMTP mail 821838032Speter sent to aliases. Suggested by Brad Knowles of the 821938032Speter Defense Information Systems Agency. 822038032Speter Call res_init() before setting RES_DEBUG; this is required by 822138032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 822238032Speter the National Computer Security Center. 822338032Speter Add xdelay= field in logs -- this is a transaction delay, telling 822438032Speter you how long it took to deliver to this address on the 822538032Speter last try. It is intended to be used for sorting mailing 822638032Speter lists to favor "quick" addresses. Provided for use by 822738032Speter the mailprio scripts (see below). 822838032Speter If a map cannot be opened, and that map is non-optional, and 822938032Speter an address requires that map for resolution, queue the 823038032Speter map instead of bouncing it. This involves creating a 823138032Speter pseudo-class of maps called "bogus-map" -- if a required 823238032Speter map cannot be opened, the class is changed to bogus-map; 823338032Speter all queries against bogus-map return "tempfail". The 823438032Speter bogus-map class is not directly accessible. A sample 823538032Speter implementation was donated by Jem Taylor of Glasgow 823638032Speter University Computing Service. 823738032Speter Fix a possible core dump when mailing to a program that talks 823838032Speter SMTP on its standard input. Fix from Keith Moore of 823938032Speter the University of Kentucky. 824038032Speter Make it possible to resolve filenames to $#local $: @ /filename; 824138032Speter previously, the "@" would cause it to not be recognized 824238032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 824338032Speter Accept a -1 signal to re-exec the daemon. This only works if 824438032Speter argv[0] is a full path to sendmail. 824538032Speter Fix bug in "addr=..." field in O option on little-endian machines 824638032Speter -- the network number wasn't being converted to network 824738032Speter byte order. Patch from Kurt Lidl of Pix Technologies 824838032Speter Corporation. 824938032Speter Pre-initialize the resolver early on; this is to avoid a bug with 825038032Speter BIND 4.9.3 that can cause the _res.retry field to get 825138032Speter reset to zero, causing all name server lookups to time 825238032Speter out. Fix from Matt Day of Artisoft. 825338032Speter Restore T line (trusted users) in config file -- but instead of 825438032Speter locking out the -f flag, they just tell whether or not 825538032Speter an X-Authentication-Warning: will be added. This really 825638032Speter just creates new entries in class 't', so "Ft/file/name" 825738032Speter can be used to read trusted user names from a file. 825838032Speter Trusted users are also allowed to execute programs even 825938032Speter if they have a shell that isn't in /etc/shells. 826038032Speter Improve NEWDB alias file rebuilding so it will create them 826138032Speter properly if they do not already exist. This had been 826238032Speter a MAYBENEXTRELEASE feature in 8.6.9. 826338032Speter Check for @:@ entry in NIS maps before starting up to avoid 826438032Speter (but not prevent, sigh) race conditions. This ought to 826538032Speter be handled properly in ypserv, but isn't. Suggested by 826638032Speter Michael Beirne of Motorola. 826738032Speter Refuse connections if there isn't enough space on the filesystem 826838032Speter holding the queue. Contributed by Robert Dana of Wolf 826938032Speter Communications. 827038032Speter Skip checking for directory permissions in the path to a file 827138032Speter when checking for file permissions iff setreuid() 827238032Speter succeeded -- it is unnecessary in that case. This avoids 827338032Speter significant performance problems when looking for .forward 827438032Speter files. Based on a suggestion by Win Bent of USC. 827538032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 827638032Speter arbitrary ruleset number assigned or "Sname = integer" 827738032Speter to assign a specific ruleset number. Reference is 827838032Speter $>name_or_number. Names can be composed of alphas, digits, 827938032Speter underscore, or hyphen (first character must be non-numeric). 828038032Speter Allow -o flag on AliasFile lines to make the alias file optional. 828138032Speter From Bryan Costales of ICSI. 828238032Speter Add NoRecipientAction option to handle the case where there is 828338032Speter no legal recipient header in the message. It can take 828438032Speter on values: 828538032Speter None Leave the message as is. The 828638032Speter message will be passed on even 828738032Speter though it is in technically 828838032Speter illegal syntax. 828938032Speter Add-To Add a To: header with any 829038032Speter recipients that it can find from 829138032Speter the envelope. This risks exposing 829238032Speter Bcc: recipients. 829338032Speter Add-Apparently-To Add an Apparently-To: header. This 829438032Speter has almost no redeeming social value, 829538032Speter and is provided only for back 829638032Speter compatibility. 829738032Speter Add-To-Undisclosed Add a header reading 829838032Speter To: undisclosed-recipients:; 829938032Speter which will have the effect of 830038032Speter making the message legal without 830138032Speter exposing Bcc: recipients. 830238032Speter Add-Bcc To add an empty Bcc: header. 830338032Speter There is a chance that mailers down 830438032Speter the line will delete this header, 830538032Speter which could cause exposure of Bcc: 830638032Speter recipients. 830738032Speter The default is NoRecipientAction=None. 830838032Speter Truncate (rather than delete) Bcc: lines in the header. This 830938032Speter should prevent later sendmails (at least, those that don't 831038032Speter themselves delete Bcc:) from considering this message to 831138032Speter be non-conforming -- although it does imply that non-blind 831238032Speter recipients can see that a Bcc: was sent, albeit not to whom. 831338032Speter Add SafeFileEnvironment option. If declared, files named as delivery 831438032Speter targets must be regular files in addition to the regular 831538032Speter checks. Also, if the option is non-null then it is used as 831638032Speter the name of a directory that is used as a chroot(2) 831738032Speter environment for the delivery; the file names listed in an 831838032Speter alias or forward should include the name of this root. 831938032Speter For example, if you run with 832038032Speter O SafeFileEnvironment=/arch 832138032Speter then aliases should reference "/arch/rest/of/path". If a 832238032Speter value is given, sendmail also won't try to save to 832338032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 832438032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 832538032Speter Support -A flag for alias files; this will comma concatenate like 832638032Speter entries. For example, given the aliases: 832738032Speter list: member1 832838032Speter list: member2 832938032Speter and an alias file declared as: 833038032Speter OAhash:-A /etc/aliases 833138032Speter the final alias inserted will be "list: member1,member2"; 833238032Speter without -A you will get an error on the second and subsequent 833338032Speter alias for "list". Contributed by Bryan Costales of ICSI. 833438032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 833538032Speter Fix a problem that could cause very long addresses to core dump in 833638032Speter some special circumstances. Problem pointed out by Allan 833738032Speter Johannesen. 833838032Speter (Internal change.) Change interface to expand() (macro expansion) 833938032Speter to be simpler and more consistent. 834038032Speter Delete check for funny qf file names. This didn't really give 834138032Speter any extra security and caused some people some problems. 834238032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 834338032Speter at compile time.) Suggested by Kyle Jones of UUNET. 834438032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 834538032Speter merge with DSN code; this is simpler and more consistent. 834638032Speter This may affect some people who have written their own 834738032Speter checkcompat() routine. 834838032Speter (Internal change.) Eliminate `D' line in qf file. The df file 834938032Speter is now assumed to be the same name as the qf file (with 835038032Speter the `q' changed to a `d', of course). 835138032Speter Avoid forking for delivery if all recipient mailers are marked as 835238032Speter "expensive" -- this can be a major cost on some systems. 835338032Speter Essentially, this forces sendmail into "queue only" mode 835438032Speter if all it is going to do is queue anyway. 835538032Speter Avoid sending a null message in some rather unusual circumstances 835638032Speter (specifically, the RCPT command returns a temporary 835738032Speter failure but the connection is lost before the DATA 835838032Speter command). Fix from Scott Hammond of Secure Computing 835938032Speter Corporation. 836038032Speter Change makesendmail to use a somewhat more rational naming scheme: 836138032Speter Makefiles and obj directories are named $os.$rel.$arch, 836238032Speter where $os is the operating system (e.g., SunOS), $rel is 836338032Speter the release number (e.g., 5.3), and $arch is the machine 836438032Speter architecture (e.g., sun4). Any of these can be omitted, 836538032Speter and anything after the first dot in a release number can 836638032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 836738032Speter version used $os.$arch.$rel and was rather less general. 836838032Speter Change makesendmail to do a "make depend" in the target directory 836938032Speter when it is being created. This involves adding an empty 837038032Speter "depend:" entry in most Makefiles. 837138032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 837238032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 837338032Speter of the Finnish Meteorological Institute. 837438032Speter Fix problem that could cause multiple responses to DATA command 837538032Speter on header syntax errors (e.g., lines beginning with colons). 837638032Speter Problem noted by Jens Thomassen of the University of Oslo. 837738032Speter Don't let null bytes in headers cause truncation of the rest of 837838032Speter the header. 837938032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 838038032Speter Increase timeouts on message data puts to allow time for receivers 838138032Speter to canonify addresses in headers on the fly. This is still 838238032Speter a rather ugly heuristic. From Motonori Nakamura. 838338032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 838438032Speter records are not used when canonifying names, and when MX 838538032Speter lookups are done for addressing they must be fully 838638032Speter qualified. This is useful if you have a wildcard MX record, 838738032Speter although it may cause other problems. In general, don't use 838838032Speter wildcard MX records. Patch from Motonori Nakamura. 838938032Speter Eliminate default two-line SMTP greeting message. Instead of 839038032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 839138032Speter is added between the first and second word of the first 839238032Speter line of the greeting message (i.e., immediately after the 839338032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 839438032Speter compile flag. Old sendmails won't see the ESMTP, but that's 839538032Speter acceptable because SIZE was the only useful extension that 839638032Speter old sendmails understand. 839738032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 839838032Speter invoked state dumps. From Masaharu Onishi. 839938032Speter Allow on-line comments in .forward and :include: files; they are 840038032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 840138032Speter is a space or a tab. This is intended for native 840238032Speter representation of non-ASCII sets such as Japanese, where 840338032Speter existing encodings would be unreadable or would lose 840438032Speter data -- for example, 840538032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 840638032Speter (romanized/less information) 840738032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 840838032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 840938032Speter (with MIME encoding, not human readable) 841038032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 841138032Speter (native encoding with ISO-2022-JP) 841238032Speter The last form is human readable in the Japanese environment. 841338032Speter Based on a fix from (surprise!) Motonori Nakamura. 841438032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 841538032Speter messages to that host; these are most frequently associated 841638032Speter with addresses rather than the host, with the exception of 841738032Speter 421 (service shutting down). The effect was to cause queues 841838032Speter to sometimes take an excessive time to flush. Reported by 841938032Speter Robert Sargent of Southern Geographics Technologies and 842038032Speter Eric Prestemon of American University. 842138032Speter Add Nice=N mailer option to set the niceness at which a mailer will 842238032Speter run. This is actually a relative niceness (that is, an 842338032Speter increment on the background value). 842438032Speter Log queue runs that are skipped due to high loads. They are logged 842538032Speter at LOG_INFO priority iff the log level is > 8. Contributed 842638032Speter by Bruce Nagel of Data General. 842738032Speter Allow the error mailer to accept a DSN-style error status code 842838032Speter instead of an sysexits status code in the host part. 842938032Speter Anything with a dot will be interpreted as a DSN-style code. 843038032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 843138032Speter to encode characters that might be munged by an EBCDIC system 843238032Speter in addition to the set required by RFC 1521. The additional 843338032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 843438032Speter (Think of "IBM 360" as the mnemonic for this flag.) 843538032Speter Change check for mailing to files to look for a pathname of [FILE] 843638032Speter rather than looking for the mailer named *file*. The mapping 843738032Speter of leading slashes still goes to the *file* mailer. This 843838032Speter allows you to implement the *file* mailer as a separate 843938032Speter program, for example, to insert a Content-Length: header 844038032Speter or do special security policy. However, note that the usual 844138032Speter initial checking for the file permissions is still done, and 844238032Speter the program in question needs to be very careful about how 844338032Speter it does the file write to avoid security problems. 844438032Speter Be able to read ~root/.forward even if the path isn't accessible to 844538032Speter regular users. This is disrecommended because sendmail 844638032Speter sometimes does not run as root (e.g., when an unsafe option 844738032Speter is specified on the command line), but should otherwise be 844838032Speter safe because .forward files must be owned by the user for 844938032Speter whom mail is being forwarded, and cannot be a symbolic link. 845038032Speter Suggested by Forrest Aldrich of Wang Laboratories. 845138032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 845238032Speter file. This is used for canonifying hostnames when the 845338032Speter service type is "files". 845438032Speter Implement programs on F (read class from file) line. The syntax is 845538032Speter Fc|/path/to/program to read the output from the program 845638032Speter into class "c". 845738032Speter Probe the network interfaces to find alternate names for this 845838032Speter host. Requires the SIOCGIFCONF ioctl call. Code 845938032Speter contributed by SunSoft. 846038032Speter Add "E" configuration line to set or propagate environment 846138032Speter variables into children. "E<envar>" will propagate 846238032Speter the named variable from the environment when sendmail 846338032Speter was invoked into any children it calls; "E<envar>=<value>" 846438032Speter sets the named variable to the indicated value. Any 846538032Speter variables not explicitly named will not be in the child 846638032Speter environment. However, sendmail still forces an 846738032Speter "AGENT=sendmail" environment variable, in part to enforce 846838032Speter at least one environment variable, since many programs and 846938032Speter libraries die horribly if this is not guaranteed. 847038032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 847138032Speter alias databases -- new algorithm looks for the substring 847238032Speter "/yp/" in the file name. This is more portable and involves 847338032Speter less overhead. Suggested by Motonori Nakamura. 847438032Speter Dynamically allocate the queue work list so that you don't lose 847538032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 847638032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 847738032Speter should not need to be changed) and the MaxQueueRunSize option, 847838032Speter which is the absolute maximum number of jobs that will ever 847938032Speter be handled in a single queue run. Based on code contributed 848038032Speter by Brian Coan of the Institute for Global Communications. 848138032Speter Log message when a message is dropped because it exceeds the maximum 848238032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 848338032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 848438032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 848538032Speter of Mark G. Thomas Consulting. 848638032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 848738032Speter OS-dependent defines). The old semantic of -d0.1 to not 848838032Speter run the daemon in background has been moved to -d99.100, 848938032Speter and the old 52.5 flag (to avoid disconnect() from closing 849038032Speter all output files) has been moved to 52.100. This makes 849138032Speter things more consistent (flags below .100 don't change 849238032Speter semantics) and separates out the backgrounding so that 849338032Speter it doesn't happen automatically on other unrelated debugging 849438032Speter flags. 849538032Speter If -t is used but no addresses are found in the header, give an 849638032Speter error message rather than just doing nothing. Fix from 849738032Speter Motonori Nakamura. 849838032Speter On systems (like SunOS) where the effective gid is not necessarily 849938032Speter included in the group list returned by getgroups(), the 850038032Speter `restrictmailq' option could sometimes cause an authorized 850138032Speter user to not be able to use `mailq'. Fix from Charles Hannum 850238032Speter of MIT. 850338032Speter Allow symbolic service names for [IPC] mailers. Suggested by 850438032Speter Gerry Magennis of Logica International. 850538032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 850638032Speter when running DNS. For example, if the name FTP.Foo.ORG is 850738032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 850838032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 850938032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 851038032Speter This is technically illegal under RFC 822 and 1123, but the 851138032Speter IETF is moving toward legalizing it. Note that turning on 851238032Speter this option is not sufficient to guarantee that a downstream 851338032Speter neighbor won't rewrite the address for you. 851438032Speter Add "-m" flag to makesendmail script -- this tells you what object 851538032Speter directory and Makefile it will use, but doesn't actually do 851638032Speter the make. 851738032Speter Do some additional checking on the contents of the qf file to try 851838032Speter to detect attacks against the qf file. In particular, 851938032Speter abort on any line beginning "From ", and add an "end of 852038032Speter file" line -- any data after that line is prohibited. 852138032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 852238032Speter choices. This can be overridden in the Makefile by using 852338032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 852438032Speter (to the extent that we know it) or by defining 852538032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 852638032Speter sendmail 8 to have more consistent installation instructions. 852738032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 852838032Speter of Sun Microsystems. 852938032Speter Improved symbol table hash function from Eric Wassenaar. This one 853038032Speter is at least 50% faster. 853138032Speter Fix problem that didn't notice that timeout on file open was a 853238032Speter transient error. Fix from Larry Parmelee of Cornell 853338032Speter University. 853438032Speter Allow comments (lines beginning with a `#') in files read for 853538032Speter classes. Suggested by Motonori Nakamura. 853638032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 853738032Speter of dropping out entirely. This makes testing some of the 853838032Speter name server lookups easier to deal with when there are 853938032Speter hung servers. From Motonori Nakamura. 854038032Speter Add new ${opMode} macro that is set to the current operation mode 854138032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 854238032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 854338032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 854438032Speter Kind of like queue-only mode (Odq) except it tries to avoid 854538032Speter any external service requests; for dial-on-demand hosts that 854638032Speter want to minimize DNS lookups when mail is being queued. For 854738032Speter this to work you will also have to make sure that gethostbyname 854838032Speter of your local host name does not do a DNS lookup. 854938032Speter Improved handling of "out of space" conditions from John Myers of 855038032Speter Carnegie Mellon. 855138032Speter Improved security for mailing to files on systems that have fchmod(2) 855238032Speter support. 855338032Speter Improve "cannot send message for N days" message -- now says "could 855438032Speter not send for past N days". Suggested by Tom Moore of AT&T 855538032Speter Global Information Solutions. 855638032Speter Less misleading Subject: line on messages sent to postmaster only. 855738032Speter From Motonori Nakamura. 855838032Speter Avoid duplicate error messages on bad command line flags. From 855938032Speter Motonori Nakamura. 856038032Speter Better error message for case where ruleset 0 falls off the end 856138032Speter or otherwise does not resolve to a canonical triple. 856238032Speter Fix a problem that could cause multiple bounce messages if a bad 856338032Speter address was sent along with a good address to an SMTP 856438032Speter site where that SMTP site returned a 4yz code in response 856538032Speter to the final dot of the data. Problem reported by David 856638032Speter James of British Telecom. 856738032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 856838032Speter from Alexander Dupuy of System Management ARTS. 856938032Speter Delete duplicates in MX lists -- believe it or not, there are sites 857038032Speter that list the same host twice in an MX list. This deletion 857138032Speter only works on adjacent preferences, so an MX list that 857238032Speter had A=5, B=10, A=15 would leave both As, but one that had 857338032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 857438032Speter just in case there is something weird I haven't thought of. 857538032Speter Suggested by Barry Shein of Software Tool & Die. 857638032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 867138032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 867238032Speter University of Brno (Czech Republic). 867338032Speter KSR OS 1.2.2 support from Todd Miller of the University 867438032Speter of Colorado. 867538032Speter UX4800 support from Kazuhisa Shimizu of NEC. 867638032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 867738032Speter in type ``btree'' maps. The semantics of this are undefined 867838032Speter for regular maps, but it can be useful for the user database. 867938032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 868038032Speter lookups while the rebuild is going on. There is a race 868138032Speter condition between the open(... O_TRUNC ...) and the lock 868238032Speter on the file, but it should be quite small. 868338032Speter SMRSH: sendmail restricted shell added to the release. This can 868438032Speter be used as an alternative to /bin/sh for the "prog" mailer, 868538032Speter giving the local administrator more control over what 868638032Speter programs can be run from sendmail. 868738032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 868838032Speter part of the release proper, and isn't fully supported; in 868938032Speter particular, it does not run on System V based systems and 869038032Speter never will. 869138032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 869238032Speter to allow rmail to compile on systems that don't have 869338032Speter function prototypes and systems that don't have snprintf. 869438032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 869538032Speter lists by transaction delay times so that addresses that 869638032Speter respond quickly get sent first. This is to prevent very 869738032Speter sluggish servers from delaying other peoples' mail. 869838032Speter Contributed by Tony Sanders of BSDI. 869938032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 870038032Speter of BSDI. This has a lot of comments to help people out. 870138032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 870238032Speter put this on the m4 command line. On GNU m4 (which 870338032Speter supports the __file__ primitive) you can run m4 in an 870438032Speter arbitrary directory -- use either: 870538032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 870638032Speter or 870738032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 870838032Speter On other versions of m4 that don't support __file__, you 870938032Speter can use: 871038032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 871138032Speter (Note the trailing slash on the _CF_DIR_ definition.) 871238032Speter Old versions of m4 will default to _CF_DIR_=.. for back 871338032Speter compatibility. 871438032Speter CONFIG: fix mail from <> so it will properly convert to 871538032Speter MAILER-DAEMON on local addresses. 871638032Speter CONFIG: fix code that was supposed to catch colons in host 871738032Speter names. Problem noted by John Gardiner Myers of CMU. 871838032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 871938032Speter From Paul Riddle of the University of Maryland, Baltimore 872038032Speter County. 872138032Speter CONFIG: Catch and reject "." as a host address. 872238032Speter CONFIG: Generalize domaintable to look up all domains, not 872338032Speter just unqualified ones. 872438032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 872538032Speter was never used and didn't work anyway. 872638032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 872738032Speter and d on all mailers in the UUCP class. 872838032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 872938032Speter look for an alias for "user+detail", then for "user+*", and 873038032Speter finally for "user". This is intended for forwarding mail 873138032Speter for system aliases such as root and postmaster to a 873238032Speter centralized hub. 873338032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 873438032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 873538032Speter The F=8 flag is also set on the "relay" mailer, since 873638032Speter this is expected to be another sendmail. 873738032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 873838032Speter the name of the UUCP_RELAY -- in some cases, this is the 873938032Speter wrong value (e.g., when we have local UUCP connections), 874038032Speter and this can create unreplyable addresses. From Chip 874138032Speter Rosenthal of Unicom. 874238032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 874364562Sgshapiro Received: header inserted into all messages. Suggested by 874438032Speter Gary Mills of the University of Manitoba. 874538032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 874643730Speter to get the old behavior. I did this upon observing 874738032Speter that almost everyone needed this feature, and that the 874838032Speter concept I was trying to make happen didn't work with 874938032Speter some user agents anyway. FEATURE(notsticky) still works, 875038032Speter but it is a no-op. 875138032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 875238032Speter names are sent, rather than immediately diagnosing them 875338032Speter as User Unknown. 875438032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 875538032Speter and RELAY_MAILER_ARGS to set the arguments for the 875638032Speter indicated mailers. All default to "IPC $h". Patch from 875738032Speter Larry Parmelee of Cornell University. 875838032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 875938032Speter on the client side" and F=P to get an appropriate 876038032Speter return-path. From Kimmo Suominen. 876138032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 876238032Speter as the local mailer. For addresses of the form "user+detail" 876338032Speter the "detail" part is passed to procmail via the -a flag. 876438032Speter Contributed by Kimmo Suominen. 876538032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 876638032Speter use from mailertables. This lets you execute arbitrary 876738032Speter procmail scripts. Contributed by Kimmo Suominen. 876838032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 876938032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 877038032Speter Paul Southworth of CICNet Systems Support. 877138032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 877238032Speter This causes the null return path to be rewritten as 877338032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 877438032Speter From Michael Hohmuth of Technische Universitat Dresden. 877538032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 877638032Speter list us as the best possible MX record to be treated as 877738032Speter though they were local (essentially, assume that they 877838032Speter are included in $=w). This can cause additional DNS 877938032Speter traffic, but is easier to administer if this fits your 878038032Speter local model. It does not work reliably if there are 878138032Speter multiple hosts that share the best MX preference. 878238032Speter Code contributed by John Oleynick of Rutgers. 878338032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 878438032Speter SHell) instead of /bin/sh as the program used for delivery 878538032Speter to programs. If an argument is included, it is used as 878638032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 878738032Speter assumed. 878838032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 878938032Speter size of messages to the local and procmail mailers 879038032Speter respectively. Contributed by Brad Knowles of the Defense 879138032Speter Information Systems Agency. 879238032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 879338032Speter (just like text outside of angle brackets) in order to 879438032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 879538032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 879638032Speter any real systems any more) and tweak the DOMAIN macro 879738032Speter so that it is less likely that users will accidentally use 879838032Speter the Berkeley defaults. Also, create some generic files 879938032Speter that really can be used in the real world. 880038032Speter CONFIG: Add new configuration macros to set character sets for 880138032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 880238032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 880338032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 880438032Speter The old name will still be accepted for a while at least. 880538032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 880638032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 880738032Speter As with all relays, it can be ``mailer:hostname''. Suggested 880838032Speter by Scott Hutton. 880938032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 881038032Speter by Barb Dijker of Labyrinth Computer Services. 881138032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 881238032Speter performance for large alias files, and this confused many 881338032Speter people. 881438032Speter CONFIG: Add confCF_VERSION to append local information to the 881538032Speter configuration version number displayed during SMTP startup. 881638032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 881738032Speter would only work when locally addressed. Fix from 881838032Speter Edvard Tuinder of Cistron Internet Services. 881938032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 882043730Speter "n" (CheckAliases) is set when rebuilding alias database. 882138032Speter Based on code contributed by Claude Marinier. 882238032Speter CONFIG: Allow mailertable to have values of the form 882338032Speter ``error:code message''. The ``code'' is a status code 882438032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 882538032Speter Contributed by David James <dwj@agw.bt.co.uk>. 882638032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 882738032Speter sender domains that will be replaced with the masquerade name. 882838032Speter These domains will not be treated as local, but if mail passes 882938032Speter through with sender addresses in those domains they will be 883038032Speter replaced by the masquerade name. These can also be specified 883138032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 883238032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 883338032Speter as well as the header. Substantial improvements to this 883438032Speter code were contributed by Per Hedeland. 883538032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 883638032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 883738032Speter by Kimmo Suominen. 883838032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 883938032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 884038032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 884138032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 884238032Speter UUCP addressing.

This caused UnixWare 898538032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 898638032Speter Novell Labs Europe. 898738032Speter Fix problem with static linking of local getopt routine when 898838032Speter using GNU's ld command. Fix from John Kennedy of 898938032Speter Cal State Chico. 899038032Speter It was possible to turn off privacy flags. Problem noted by 899138032Speter *Hobbit*. 899238032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 899338032Speter and Liudvikas Bukys. 899438032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 899538032Speter from Spider Boardman. 899638032Speter CONFIG: No changes (version number only, to keep it in sync 899738032Speter with the binaries). 899838032Speter 899964562Sgshapiro8.6.10/8.6.10 1995/02/10 900038032Speter SECURITY: Diagnose bogus values to some command line flags that 900138032Speter could allow trash to get into headers and qf files. 900238032Speter Validate the name of the user returned by the IDENT protocol. 900338032Speter Some systems that really dislike IDENT send intentionally 900438032Speter bogus information. Problem pointed out by Michael Bushnell 900538032Speter of the Free Software Foundation. Has some security 900638032Speter implications. 900738032Speter Fix a problem causing error messages about DNS problems when 900838032Speter the host name contained a percent sign to act oddly 900938032Speter because it was passed as a printf-style format string. 901038032Speter In some cases this could cause core dumps. 901138032Speter Avoid possible buffer overrun in returntosender() if error 901238032Speter message is quite long. From Fletcher Mattox of the 901338032Speter University of Texas. 901438032Speter Fix a problem that would silently drop "too many hops" error 901538032Speter messages if and only if you were sending to an alias. 901638032Speter From Jon Giltner of the University of Colorado and 901738032Speter Dan Harton of Oak Ridge National Laboratory. 901838032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 901938032Speter set and e->e_message was null. Fix from Bruce Nagel of 902038032Speter Data General. 902138032Speter Fix problem that can still cause df files to be left around 902238032Speter after "hop count exceeded" messages. Fix from Andrew 902338032Speter Chang and Shau-Ping Lo of SunSoft. 902438032Speter Fix a problem that can cause buffer overflows on very long 902538032Speter user names (as might occur if you piped to a program 902638032Speter with a lot of arguments). 902738032Speter Avoid returning an error and re-queueing if the host signature 902838032Speter is null; this can occur on addresses like ``user@.''. 902938032Speter Problem noted by Wesley Craig and the University of 903038032Speter Michigan. 903138032Speter Avoid possible calls to malloc(0) if MCI caching is turned 903238032Speter off. Bug fix from Pierre David of the Laboratoire 903338032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 903438032Speter Universite de Versailles - St Quentin, and Jacky 903538032Speter Thibault. 903638032Speter Make a local copy of the line being sent via senttolist() -- in 903738032Speter some cases, buffers could get trashed by map lookups 903838032Speter causing it to do unexpected things. This also simplifies 903938032Speter some of the map code. 904038032Speter CONFIG: No changes (version number only, to keep it in sync 904138032Speter with the binaries). 904238032Speter 904364562Sgshapiro8.6.9/8.6.9 1994/04/19 904438032Speter Do all mail delivery completely disconnected from any terminal. 904538032Speter This provides consistency with daemon delivery and 904638032Speter may have some security implications. 904738032Speter Make sure that malloc doesn't get called with zero size, 904838032Speter since that fails on some systems. Reported by Ed 904938032Speter Hill of the University of Iowa. 905038032Speter Fix multi-line values for $e (SMTP greeting message). Reported 905138032Speter by Mike O'Connor of Ford Motor Company. 905238032Speter Avoid syserr if no NIS domain name is defined, but the map it 905338032Speter is trying to open is optional. From Win Bent of USC. 905438032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 905538032Speter Hesiod support for UDB from Todd Miller of the University of 905638032Speter Colorado. Use "hesiod" as the service name in the U 905738032Speter option. 905838032Speter Fix a problem that failed to set the "authentic" host name (that 905938032Speter is, the one derived from the socket info) if you called 906038032Speter sendmail -bs from inetd. Based on code contributed by 906138032Speter Todd Miller (this problem was also reported by Guy Helmer 906238032Speter of Dakota State University). This also fixes a related 906338032Speter problem reported by Liudvikas Bukys of the University of 906438032Speter Rochester. 906538032Speter Parameterize "nroff -h" in all the Makefiles so people with 906638032Speter variant versions can use them easily. Suggested by 906738032Speter Peter Collinson of Hillside Systems. 906838032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 906938032Speter spaces between parameters instead of one. Reported by 907038032Speter Valdis Kletnieks of Virginia Tech. 907138032Speter Reduce the number of system calls during message collection by 907238032Speter using global timeouts around the collect() loop. This 907338032Speter code was contributed by Eric Wassenaar. 907438032Speter If the initial hostname name gathering results in a name 907538032Speter without a dot (usually caused by NIS misconfiguration) 907638032Speter and BIND is compiled in, directly access DNS to get 907738032Speter the canonical name. This should make life easier for 907838032Speter Solaris systems. If it still can't be resolved, and 907938032Speter if the name server is listed as "required", try again 908038032Speter in 30 seconds. If that also fails, exit immediately to 908138032Speter avoid bogus "config error: mail loops back to myself" 908238032Speter messages. 908338032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 908438032Speter message to explain how much space was available and 908538032Speter sound a bit less threatening. Suggested by Stan Janet 908638032Speter of the National Institute of Standards and Technology. 908738032Speter If mail is delivered to an alias that has an owner, deliver any 908838032Speter requested return-receipt immediately, and strip the 908938032Speter Return-Receipt-To: header from the subsequent message. 909038032Speter This prevents a certain class of denial of service 909138032Speter attack, arguably gives more reasonable semantics, and 909238032Speter moves things more towards what will probably become a 909338032Speter network standard. Suggested by Christopher Davis of 909438032Speter Kapor Enterprises. 909538032Speter Add a "noreceipts" privacy flag to turn off all return receipts 909638032Speter without recompiling. 909738032Speter Avoid printing ESMTP parameters as part of the error message 909838032Speter if there are errors during parsing. This change is 909938032Speter purely cosmetic. 910038032Speter Avoid sending out error messages during the collect phase of 910138032Speter SMTP; there is an MVS mailer from UCLA that gets 910238032Speter confused by this. Of course, I think it's their bug.... 910338032Speter Check for the $j macro getting undefined, losing a dot, or getting 910438032Speter lost from $=w in the daemon before accepting a connection; 910538032Speter if it is, it dumps state, prints a LOG_ALERT message, 910638032Speter and drops core for debugging. This is an attempt to 910738032Speter track down a bug that I thought was long since gone. 910838032Speter If you see this, please forward the log fragment to 910938032Speter sendmail@sendmail.ORG. 911038032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 911138032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 911238032Speter Wolfhugel. 911338032Speter Instead of trying to truncate the listen queue for the server 911438032Speter SMTP port when the load average is too high, just close 911538032Speter the port completely and reopen it later as needed. 911638032Speter This ensures that the other end gets a quick "connection 911738032Speter refused" response, and that the connection can be 911838032Speter recovered later. In particular, some socket emulations 911938032Speter seem to get confused if you tweak the listen queue 912038032Speter size around and can never start listening to connections 912138032Speter again. The down side is that someone could start up 912238032Speter another daemon process in the interim, so you could 912338032Speter have multiple daemons all not listening to connections; 912438032Speter this could in turn cause the sendmail.pid file to be 912538032Speter incorrect. A better approach might be to accept the 912638032Speter connection and give a 421 code, but that could break 912743730Speter other mailers in mysterious ways and have paging behavior 912838032Speter implications. 912938032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 913038032Speter set debugging on the wrong socket. From Eric Wassenaar. 913138032Speter When creating a df* temporary file, be sure you truncate any 913238032Speter existing data in the file -- otherwise system crashes 913338032Speter and the like could result in extra data being sent. 913438032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 913538032Speter doc directory. This includes some additional 913638032Speter information. 913738032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 913838032Speter of recipient envelope addresses. This should have been 913938032Speter handled by the $&h trick, but broke if people were 914038032Speter mixing domainized and UUCP addresses. They should 914138032Speter probably have converted all the way over to uucp-uudom 914238032Speter instead of uucp-{new,old}, but the failure mode was to 914338032Speter loop the mail, which was bad news. 914438032Speter Portability fixes: 914538032Speter Newer BSDI systems (several people). 914638032Speter Older BSDI systems from Christophe Wolfhugel. 914738032Speter Intergraph CLIX, from Paul Southworth of CICNet. 914838032Speter UnixWare, from Evan Champion. 914938032Speter NetBSD from Adam Glass. 915038032Speter Solaris from Quentin Campbell of the University of 915138032Speter Newcastle upon Tyne. 915238032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 915338032Speter Corporation. 915438032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 915538032Speter SunOS (it has setsid() and setvbuf() calls) from 915638032Speter Jonathan Kamens of OpenVision Technologies. 915738032Speter HP-UX from Tor Lillqvist. 915838032Speter New Files: 915938032Speter src/Makefile.CLIX 916038032Speter src/Makefile.NCR3000 916138032Speter doc/changes/Makefile 916238032Speter doc/changes/changes.me 916338032Speter doc/changes/changes.ps 916438032Speter 916564562Sgshapiro8.6.8/8.6.6 1994/03/21 916638032Speter SECURITY: it was possible to read any file as root using the 916738032Speter E (error message) option. Reported by Richard Jones; 916838032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 916938032Speter 917064562Sgshapiro8.6.7/8.6.6 1994/03/14 917138032Speter SECURITY: it was possible to get root access by using weird 917238032Speter values to the -d flag. Thanks to Alain Durand of 917338032Speter INRIA for forwarding me the notice from the bugtraq 917438032Speter list. 917538032Speter 917664562Sgshapiro8.6.6/8.6.6 1994/03/13 917738032Speter SECURITY: the ability to give files away on System V-based 917838032Speter systems proved dangerous -- don't run as the owner 917938032Speter of a :include: file on a system that allows giveaways. 918038032Speter Unfortunately, this also applies to determining a 918138032Speter valid shell. 918238032Speter IMPORTANT: Previous versions weren't expiring old connections 918338032Speter in the connection cache for a long time under some 918438032Speter circumstances. This could result in resource exhaustion, 918538032Speter both at your end and at the other end. This checks the 918638032Speter connections for timeouts much more frequently. From 918738032Speter Doug Anderson of NCSC. 918838032Speter Fix a glitch that snuck in that caused programs to be run as 918938032Speter the sender instead of the recipient if the mail was 919038032Speter from a local user to another local user. From 919138032Speter Motonori Nakamura of Kyoto University. 919238032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 919338032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 919438032Speter Bryan Costales of ICSI. 919538032Speter Change the method used to declare the "statfs" availability; 919638032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 919738032Speter tweaking in conf.c, there is a single #define called 919838032Speter SFS_TYPE which takes on one of six values (SFS_NONE 919938032Speter for no statfs availability, SFS_USTAT for the ustat(2) 920038032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 920138032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 920238032Speter statfs(2) call with the declarations in <sys/vfs.h>, 920338032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 920438032Speter Fix glitch in NetInfo support that could return garbage if 920538032Speter there was no "/locations/sendmail" property. From 920638032Speter David Meyer of the University of Virginia. 920738032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 920838032Speter to allow Linux to turn it off even though it is a 920938032Speter BSD-like system. 921038032Speter Allow setting of "ident" timeout to zero to turn off the ident 921138032Speter protocol entirely. 921238032Speter Make 7-bit stripping local to a connection (instead of to a 921338032Speter mailer); this allows you to specify that SMTP is a 921438032Speter 7-bit channel, but revert to 8-bit should it advertise 921538032Speter that it supports 8BITMIME. You still have to specify 921638032Speter mailer flag 7 to get this stripping at all. 921738032Speter Improve makesendmail script so it handles more cases automatically. 921838032Speter Tighten up restrictions on taking ownership of :include: files 921938032Speter to avoid problems on systems that allow you to give away 922038032Speter files. 922138032Speter Fix a problem that made it impossible to rebuild the alias 922238032Speter file if it was on a read-only file system. From 922338032Speter Harry Edmon of the University of Washington. 922438032Speter Improve MX randomization function. From John Gardiner Myers 922538032Speter of CMU. 922638032Speter Fix a minor glitch causing a bogus message to be printed (used 922738032Speter %s instead of %d in a printf string for the line number) 922838032Speter when a bad queue file was read. From Harry Edmon. 922938032Speter Allow $s to remain NULL on locally generated mail. I'm not 923038032Speter sure this is necessary, but a lot of people have complained 923138032Speter about it, and there is a legitimate question as to whether 923238032Speter "localhost" is legal as an 822-style domain. 923338032Speter Fix a problem with very short line lengths (mailer L= flag) in 923438032Speter headers. This causes a leading space to be added onto 923538032Speter continuation lines (including in the body!), and also 923638032Speter tries to wrap headers containing addresses (From:, To:, 923738032Speter etc) intelligently at the shorter line lengths. Problem 923838032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 923938032Speter Log the real user name when logging syserrs, since these can have 924038032Speter security implications. Suggested by several people. 924138032Speter Fix address logging of cached connections -- it used to always 924238032Speter log the numeric address as zero. This is a somewhat 924338032Speter bogus implementation in that it does an extra system 924438032Speter call, but it should be an inexpensive one. Fix from 924538032Speter Motonori Nakamura. 924638032Speter Tighten up handling of short syslog buffers even more -- there 924738032Speter were cases where the outgoing relay= name was too long 924838032Speter to share a line with delay= and mailer= logging. 924938032Speter Limit the overhead on split envelopes to one open file descriptor 925038032Speter per envelope -- previously the overhead was three 925138032Speter descriptors. This was in response to a problem reported 925238032Speter by P{r (Pell) Emanuelsson. 925338032Speter Fixes to better handle the case of unexpected connection closes; 925438032Speter this redirects the output to the transcript so the info 925538032Speter is not lost. From Eric Wassenaar. 925638032Speter Fix potential string overrun if you macro evaluate a string that 925738032Speter has a naked $ at the end. Problem noted by James Matheson 925838032Speter <jmrm@eng.cam.ac.uk>. 925938032Speter Make default error number on $#error messages 553 (``Requested 926038032Speter action not taken: mailbox name not allowed'') instead of 926138032Speter 501 (``Syntax error in parameters or arguments'') to 926238032Speter avoid bogus "protocol error" messages. 926338032Speter Strip off any existing trailing dot on names during $[ ... $] 926438032Speter lookup. This prevents it from ending up with two dots 926538032Speter on the end of dot terminated names. From Wesley Craig 926638032Speter of the University of Michigan and Bryan Costales of ICSI. 926738032Speter Clean up file class reading so that the debugging information is 926838032Speter more informative. It hadn't been using setclass, so you 926938032Speter didn't see the class items being added. 927038032Speter Avoid core dump if you are running a version of sendmail where 927138032Speter NIS is compiled in, and you specify an NIS map, but 927238032Speter NIS is not running. Fix from John Oleynick of 927338032Speter Rutgers. 927438032Speter Diagnose bizarre case where res_search returns a failure value, 927538032Speter but sets h_errno to a success value. 927638032Speter Make sure that "too many hops" messages are considered important 927738032Speter enough to send an error to the Postmaster (that is, the 927838032Speter address specified in the P option). This fix should 927938032Speter help problems that cause the df file to be left around 928038032Speter sometimes -- unfortunately, I can't seem to reproduce 928138032Speter the problem myself. 928238032Speter Avoid core dump (null pointer reference) on EXPN command; this 928338032Speter only occurred if your log level was set to 10 or higher 928438032Speter and the target account was an alias or had a .forward file. 928538032Speter Problem noted by Janne Himanka. 928638032Speter Avoid "denial of service" attacks by someone who is flooding your 928738032Speter SMTP port with bad commands by shutting the connection 928838032Speter after 25 bad commands are issued. From Kyle Jones of 928938032Speter UUNET. 929038032Speter Fix core dump on error messages with very long "to" buffers; 929138032Speter fmtmsg overflows the message buffer. Fixed by trimming 929238032Speter the to address to 203 characters. Problem reported by 929338032Speter John Oleynick. 929438032Speter Fix configuration for HASFLOCK -- there were some spots where 929538032Speter a #ifndef was incorrectly #ifdef. Pointed out by 929638032Speter George Baltz of the University of Maryland. 929738032Speter Fix a typo in savemail() that could cause the error message To: 929838032Speter lists to be incorrect in some places. From Motonori 929938032Speter Nakamura. 930038032Speter Fix a glitch that can cause duplicate error messages on split 930138032Speter envelopes where an address on one of the lists has a 930238032Speter name server failure. Fix from Voradesh Yenbut of the 930338032Speter University of Washington. 930438032Speter Fix possible bogus pointer reference on ESMTP parameters that 930538032Speter don't have an ``=value'' part. 930638032Speter CNAME loops caused an error message to be generated, but also 930738032Speter re-queued the message. Changed to just re-queue the 930838032Speter message (it's really hard to just bounce it because 930938032Speter of the weird way the name server works in the presence 931038032Speter of CNAME loops). Problem noted by James M.R.Matheson 931138032Speter of Cambridge University. 931238032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 931338032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 931438032Speter user name. Suggested by Andreas Stolcke of ICSI. 931538032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 931638032Speter override it easily in the Makefile -- that is, you can 931738032Speter turn it off using -DNAMED_BIND=0. 931838032Speter If a gethostbyname(...) of an address with a trailing dot fails, 931938032Speter try it without the trailing dot. This is because if 932038032Speter you have a version of gethostbyname() that falls back 932138032Speter to NIS or the /etc/hosts file it will fail to find 932238032Speter perfectly reasonable names that just don't happen to 932338032Speter be dot terminated in the hosts file. You don't want to 932438032Speter strip the dot first though because we're trying to ensure 932538032Speter that country names that match one of your subdomains get 932638032Speter a chance. 932738032Speter PRALIASES: fix bogus output on non-null-terminated strings. 932838032Speter From Bill Gianopoulos of Raytheon. 932938032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 933038032Speter This was in code intended to only catch the self-literal 933138032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 933238032Speter IP address), but the code was broken. However, it will 933338032Speter still do this if $M is defined; this is necessary to 933438032Speter get client configurations to work (sigh). Note that this 933538032Speter means that $M overrides :mailname entries in the user 933638032Speter database! Problem noted by Paul Southworth. 933738032Speter CONFIG: Fix definition of Solaris help file location. From 933838032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 933938032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 934038032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 934138032Speter and USENET_MAILER_MAX to tweak the maximum message 934238032Speter size for various mailers. 934338032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 934438032Speter instead of assuming that it is "inews" for consistency 934538032Speter with other mailers. From Michael Corrigan of UC San Diego. 934638032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 934738032Speter qualify the address in the SMTP envelope as user@{relay|hub} 934838032Speter instead of user@$j. From Bill Wisner of The Well. 934938032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 935038032Speter CONFIG: Don't turn off case mapping of user names in the local 935138032Speter mailer for IRIX. This was different than most every other 935238032Speter system. 935338032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 935438032Speter envelope. Noted by Thierry Besancon 935538032Speter <besancon@excalibur.ens.fr>. 935638032Speter CONFIG: Don't include -z by default on uux line -- most systems 935738032Speter don't want it set by default. Pointed out by Philippe 935838032Speter Michel of Thomson CSF. 935938032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 936038032Speter host name was foo.bar.ray.com and you matched against 936138032Speter ".ray.com", the old implementation bound %1 to "bar" 936238032Speter instead of "foo.bar". Also, allow "." in the mailertable 936338032Speter to match anything -- essentially, take over SMART_HOST. 936438032Speter This also moves matching of explicit local host names 936538032Speter before the mailertable so they don't have to be special 936638032Speter cased in the mailertable data. Reported by Bill 936738032Speter Gianopoulos of Raytheon; the fix for the %1 binding 936838032Speter problem was contributed by Nicholas Comanos of the 936938032Speter University of Sydney. 937038032Speter CONFIG: Don't include "root" in class $=L (users to deliver 937138032Speter locally, even if a hub or relay exists) by default. 937238032Speter This is because of the known bug where definition of 937338032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 937438032Speter both and deliver into the local mailbox. 937538032Speter CONFIG: Move up bitdomain and uudomain handling so that they 937638032Speter are done before .UUCP class matching; uudomain was 937738032Speter reported as ineffective before. This also frees up 937838032Speter diversion 8 for future use. Problem reported by Kimmo 937938032Speter Suominen. 938038032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 938138032Speter into host names. As pointed out by Jonathan Kamens, 938238032Speter these are often used because either the forward or reverse 938338032Speter mapping is broken; this translation makes it broken again. 938438032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 938538032Speter Suominen. 938638032Speter Portability fixes: 938738032Speter Unicos from David L.

From 941138032Speter Bob Campbell at U.C. Berkeley. 941238032Speter Security fix: group ids were not completely set when programs 941338032Speter were invoked. This caused programs to have group 941438032Speter permissions they should not have had (usually group 941538032Speter daemon instead of their own group). In particular, 941638032Speter Perl scripts would refuse to run. 941738032Speter Security: check to make sure files that are written are not 941838032Speter symbolic links (at least under some circumstances). 941938032Speter Although this does not respond to a specific known 942038032Speter attack, it's just a good idea. Suggested by 942138032Speter Christian Wettergren. 942238032Speter Security fix: if a user had an NFS mounted home directory on 942338032Speter a system with a restricted shell listed in their 942438032Speter /etc/passwd entry, they could still execute any 942538032Speter program by putting that in their .forward file. 942638032Speter This fix prevents that by insisting that their shell 942738032Speter appear in /etc/shells before allowing a .forward to 942838032Speter execute a program or write a file. You can disable 942938032Speter this by putting "*" in /etc/shells. It also won't 943038032Speter permit world-writable :include: files to reference 943138032Speter programs or files (there's no way to disable this). 943243730Speter These behaviors are only one level deep -- for 943338032Speter example, it is legal for a world-writable :include: 943438032Speter file to reference an alias that writes a file, on 943538032Speter the assumption that the alias file is well controlled. 943638032Speter Security fix: root was not treated suspiciously enough when 943738032Speter looking into subdirectories. This would potentially 943838032Speter allow a cracker to examine files that were publicly 943938032Speter readable but in a non-publicly searchable directory. 944038032Speter Fix a problem that causes an error on QUIT on a cached 944138032Speter connection to create problems on the current job. 944238032Speter These are typically unrelated, so errors occur in 944338032Speter the wrong place. 944438032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 944538032Speter runs more responsive to load average, and fixes a 944638032Speter problem that ignored the load average in locally 944738032Speter generated mail. From Eric Wassenaar. 944838032Speter Fix possible core dump on aliases with null LHS. From 944938032Speter John Orthoefer of BB&N. 945038032Speter Revert to using flock() whenever possible -- there are just 945138032Speter too many bugs in fcntl() locking, particularly over 945238032Speter NFS, that cause sendmail to fail in perverse ways. 945338032Speter Fix a bug that causes the connection cache to get confused 945438032Speter when sending error messages. This resulted in 945538032Speter "unexpected close" messages. It should fix itself 945638032Speter on the following queue run. Problem noted by 945738032Speter Liudvikas Bukys of the University of Rochester. 945838032Speter Include $k in $=k as documented in the Install & Op Guide. 945938032Speter This seems odd, but it was documented.... From 946038032Speter Michael Corrigan of UCSD. 946138032Speter Fix problem that caused :include:s from alias files to be 946238032Speter forced to be owned by root instead of daemon 946338032Speter (actually DefUid). From Tim Irvin. 946438032Speter Diagnose unrecognized I option values -- from Mortin Forssen 946538032Speter of the Chalmers University of Technology. 946638032Speter Make "error" mailer work consistently when there is no error 946738032Speter code associated with it -- previously it returned OK 946838032Speter even though there was a real problem. Now it assumes 946938032Speter EX_UNAVAILABLE. 947038032Speter Fix bug that caused the last header line of messages that had 947138032Speter no body and which were terminated with EOF instead of 947238032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 947338032Speter Fix core dump on SMTP mail to programs that failed -- it tried 947438032Speter to go to a "next MX host" when none existed, causing 947538032Speter a core dump. From der Mouse at McGill University. 947638032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 947738032Speter this makes it easier to turn it off (using 947838032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 947938032Speter Fix YP_MASTER_NAME store to use the unupdated result of 948038032Speter gethostname() (instead of myhostname(), which tries 948138032Speter to fully qualify the name) to be consistent with 948238032Speter SunOS. If your hostname is unqualified, this fixes 948338032Speter transfers to slave servers. Bug noted by Keith 948438032Speter McMillan of Ameritech Services, Inc. 948538032Speter Fix Ultrix problem: gethostbyname() can return a very large 948638032Speter (> 500) h_length field, which causes the sockaddr 948738032Speter to be trashed. Use the size of the sockaddr instead. 948838032Speter Fix from Bob Manson of Ohio State. 948938032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 949038032Speter defined -- this confuses gethostbyname on hosts 949138032Speter file lookups, which doesn't understand the trailing 949238032Speter dot convention. 949338032Speter Log SMTP server subprocesses that die with a signal instead 949438032Speter of from a clean exit. 949538032Speter If you don't have option "I" set, don't assume that a DNS 949638032Speter "host unknown" message is authoritative -- it 949738032Speter might still be found in /etc/hosts. 949838032Speter Fix a problem that would cause Deferred: messages to be sent 949938032Speter as the subject of an error message, even though the 950038032Speter actual cause of a message was more severe than that. 950138032Speter Problem noted by Chris Seabrook of OSSI. 950238032Speter Fix race condition in DBM alias file locking. From Kyle 950338032Speter Jones of UUNET. 950438032Speter Limit delivery syslog line length to avoid bugs in some 950538032Speter versions of syslog(3). This adds a new compile time 950638032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 950738032Speter University, which is in turn derived from IDA. 950838032Speter Fix quotes inside of comments in addresses -- previously 950938032Speter it insisted that they be balanced, but the 822 spec 951038032Speter says that they should be ignored. 951138032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 951238032Speter debugging). This also evaluates ruleset 89, if set 951338032Speter (with the null input), and logs the result. This 951438032Speter should be used sparingly, since the rewrite process 951538032Speter is not reentrant. 951638032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 951738032Speter documented in the Bat Book. 951838032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 951938032Speter return an error message and did not requeue the message. 952038032Speter Fix based on code from Roland Dirlewanger of 952138032Speter Reseau Regional Aquarel, Bordeaux, France. 952238032Speter Fix a problem that caused a seg fault if you got a 421 error 952338032Speter code during some parts of connection initialization. 952438032Speter I've only seen this when talking to buggy mailers on 952538032Speter the other end, but it shouldn't give a seg fault in 952638032Speter any case. From Amir Plivatsky. 952738032Speter Fix core dump caused by a ruleset call that returns null. 952838032Speter Fix from Bryan Costales of ICSI. 952938032Speter Full-Name: field was being ignored.

From Vince 956338032Speter DeMarco. 956438032Speter Fix a glitch that sometimes caused :include:s that pointed to 956538032Speter NFS filesystems that were down to give an "aliasing/ 956638032Speter forwarding loop broken" message instead of queueing 956738032Speter the message for retry. Noted by William C Fenner of 956838032Speter the NRL Connection Machine Facility. 956938032Speter Fix a problem that could cause a core dump if the input sequence 957038032Speter had (or somehow acquired) a \231 character. 957138032Speter Make sure that route-addrs always have <angle brackets> around 957238032Speter them in non-SMTP envelopes (SMTP envelopes already do 957338032Speter this properly). 957438032Speter Avoid weird headers on unbalanced punctuation of the form: 957538032Speter ``Joe User <user)'' -- this caused reference to the 957638032Speter null macro. Fix from Rick McCarty of IO.COM. 957738032Speter Fix a problem that caused an alias "user: user@local.host" to 957838032Speter not have the QNOTREMOTE bit set; this caused configs 957938032Speter to act as if FEATURE(notsticky) was defined even when 958038032Speter it was not. The effect of the problem was to make it 958138032Speter very hard to to set up satellite sites that had a few 958238032Speter local accounts, with everything else forwarded to a 958338032Speter corporate hub. Reported by Detlef Drewanz of the 958438032Speter University of Rostock and Mark Frost of NCD. 958538032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 958638032Speter addresses. This is more efficient (fewer name server 958738032Speter calls) and fixes certain unusual configurations, such 958838032Speter as those that have ruleset 4 do something that is 958938032Speter non-idempotent unless a mailer-specific ruleset did 959038032Speter something else.

Briefly, if you are sending to host 965938032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 966038032Speter "foo!baz" remains "foo!baz", and anything else has 966138032Speter the local name prepended. 966238032Speter CONFIG: portability fixes for HP-UX. 966338032Speter DOC: several minor problems fixed in the Install & Op Guide. 966438032Speter MAKEMAP: fix core dump problem on lines that are too long or 966538032Speter which lack newline. From Mark Delany. 966638032Speter MAILSTATS: print sums of columns (total messages & kbytes 966738032Speter in and out of the system). From Tom Ferrin of UC 966838032Speter San Francisco Computer Graphics Lab. 966938032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 967038032Speter On HP-UX, /etc/sendmail.cf has been moved to 967138032Speter /usr/lib/sendmail.cf to match HP sendmail. 967238032Speter Permissions have been tightened up on world-writable 967338032Speter :include: files and accounts that have shells 967438032Speter that are not listed in /etc/shells. This may 967538032Speter cause some .forward files that have worked 967638032Speter before to start failing. 967738032Speter SIGUSR1 dumps some state to the log. 967838032Speter NEW FILES: 967938032Speter src/Makefile.DGUX 968038032Speter src/Makefile.Dynix 968138032Speter src/Makefile.FreeBSD 968238032Speter src/Makefile.Mach386 968338032Speter src/Makefile.NetBSD 968438032Speter src/Makefile.RISCos 968538032Speter src/Makefile.SCO 968638032Speter src/Makefile.SVR4 968738032Speter src/Makefile.Titan 968838032Speter cf/mailer/pop.m4 968938032Speter cf/ostype/bsdi1.0.m4 969038032Speter cf/ostype/dgux.m4 969138032Speter cf/ostype/dynix3.2.m4 969238032Speter cf/ostype/sco3.2.m4 969338032Speter makemap/Makefile.dist 969438032Speter praliases/Makefile.dist 969538032Speter 969664562Sgshapiro8.6.4/8.6.4 1993/10/31 969738032Speter Repair core-dump problem (write to read-only memory segment) 969838032Speter if you fall back to the return-to-Postmaster case in 969938032Speter savemail. Problem reported by Richard Liu. 970038032Speter Immediately diagnose bogus sender addresses in SMTP. This 970138032Speter makes quite certain that crackers can't use this 970238032Speter class of attack. 970338032Speter Reliability Fix: check return value from fclose() and fsync() 970438032Speter in a few critical places. 970538032Speter Minor problem in initsys() that reversed a condition for 970638032Speter redirecting the output channel on queue runs. It's 970738032Speter not clear this code even does anything. From Eric 970838032Speter Wassenaar of the Dutch National Institute for Nuclear 970938032Speter and High-Energy Physics. 971038032Speter Fix some problems that caused queue runs to do "too much work", 971138032Speter such as double-reading the Errors-To: header. From 971238032Speter Eric Wassenaar. 971338032Speter Error messages on writing the temporary file (including the 971438032Speter data file) were getting suppressed in SMTP -- this 971538032Speter fix causes them to be properly reported. From Eric 971638032Speter Wassenaar. 971738032Speter Some changes to support AF_UNIX sockets -- this will only 971838032Speter really become relevant in the next release, but some 971938032Speter people need it for local patches. From Michael 972038032Speter Corrigan of UC San Diego. 972138032Speter Use dynamically allocated memory (instead of static buffers) 972238032Speter for macros defined in initsys() and settime(); since 972338032Speter these can have different values depending on which 972438032Speter envelope they are in. From Eric Wassenaar. 972538032Speter Improve logging to show ctladdr on to= logging; this tells you 972638032Speter what uid/gid processes ran as. 972738032Speter Fix a problem that caused error messages to be discarded if 972838032Speter the sender address was unparseable for some reason; 972938032Speter this was supposed to fall back to the "return to 973038032Speter postmaster" case. 973138032Speter Improve aliaswait backoff algorithm. 973238032Speter Portability patches for Linux (8.6.3 required another header 973338032Speter file) (from Karl London) and SCO UNIX. 973438032Speter CONFIG: patch prog mailer to not strip host name off of envelope 973538032Speter addresses (so that it matches local again). From 973638032Speter Christopher Davis. 973738032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 973838032Speter this prevents uux from seeing lines with null names like 973938032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 974038032Speter Nakamura of Kyoto University. 974138032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 974238032Speter it shouldn't fail miserably. From Motonori Nakamura. 974338032Speter 974464562Sgshapiro8.6.2/8.6.2 1993/10/15 974538032Speter Put a "successful delivery" message in the transcript for 974638032Speter addresses that get return-receipts. 974738032Speter Put a prominent "this is only a warning" message in warning 974838032Speter messages -- some people don't read carefully enough 974938032Speter and end up sending the message several times. 975038032Speter Include reason for temporary failure in the "warning" return 975138032Speter message. Currently, it just says "cannot send for 975238032Speter four hours". 975338032Speter Fix the "Original message received" time generated for 975438032Speter returntosender messages. It was previously listed as 975538032Speter the current time. Bug reported by Eric Hagberg of 975638032Speter Cornell University Medical College. 975738032Speter If there is an error when writing the body of a message, 975838032Speter don't send the trailing dot and wait for a response 975938032Speter in sender SMTP, as this could cause the connection to 976038032Speter hang up under some bizarre circumstances. From Eric 976138032Speter Wassenaar. 976238032Speter Fix some server SMTP synchronization problems caused when 976338032Speter connections fail during message collection. From 976438032Speter Eric Wassenaar. 976538032Speter Fix a problem that can cause srvrsmtp to reject mail if the 976638032Speter name server is down -- it accepts the RCPT but rejects 976738032Speter the DATA command. Problem reported by Jim Murray of 976838032Speter Stratus. 976938032Speter Fix a problem that can cause core dumps if the config file 977038032Speter incorrectly resolves to a null hostname. Reported by 977138032Speter Allan Johannesen of WPI. 977238032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 977338032Speter by non-root users were not put into 977438032Speter X-Authentication-Warning:s as intended because the 977543730Speter config file hadn't set the PrivacyOptions yet. Fix 977638032Speter from Sven-Ove Westberg of the University of Lulea. 977738032Speter Under very odd circumstances, the alias file rebuild code 977838032Speter could get confused as to whether a database was 977938032Speter open or not. 978038032Speter Check "vendor code" on the end of V lines -- this is 978138032Speter intended to provide a hook for vendor-specific 978238032Speter configuration syntax. (This is a "new feature", 978338032Speter but I've made an exception to my rule in a belief 978438032Speter that this is a highly exceptional case.) 978538032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 978638032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 978738032Speter (from Jon Forrest of UC Berkeley) 978838032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 978938032Speter 979064562Sgshapiro8.6.1/8.6 1993/10/08 979138032Speter Portability fixes for A/UX and Encore UMAX V. 979238032Speter Fix error message handling -- if you had a name server down 979338032Speter causing an error during parsing, that message was never 979438032Speter propagated to the queue file. 979538032Speter 979664562Sgshapiro8.6/8.6 1993/10/05 979738032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 979838032Speter conf.h (other systems have the same bug). 979938032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 980038032Speter getdtablesize() instead of sysconf(); a disturbingly 980138032Speter large number of systems defined _SC_OPEN_MAX in the 980238032Speter header files but don't have the syscall. 980338032Speter Another patch to really truly ignore MX records in getcanonname 980438032Speter if trymx == FALSE. 980538032Speter Fix problem that caused the "250 IAA25499 Message accepted for 980638032Speter delivery" message to be omitted if there was an error 980738032Speter in the header of the message (e.g., a bad Errors-To: 980838032Speter line). Pointed out by Michael Corrigan of UCSD. 980938032Speter Announce name of host we are chatting when we get errors; this 981038032Speter is an IDA-ism suggested by Christophe Wolfhugel. 981138032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 981238032Speter Australian Artificial Intelligence Institute), SCO Unix 981338032Speter (from Murray Kucherawy of Hookup Communication Corp.), 981438032Speter NeXT (from Vince DeMarco and myself), Linux (from 981538032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 981638032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 981738032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 981838032Speter Some changes to get around gcc optimizer bugs. From Takahiro 981938032Speter Kanbe. 982038032Speter Fix error recovery in queueup if another tf file of the same 982138032Speter name already exists. Problem stumbled over by Bill 982238032Speter Wisner of The Well. 982338032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 982438032Speter Problem noted by Keith McMillan of Ameritech Services. 982538032Speter Deal with group permissions properly when opening .forward and 982638032Speter :include: files. This relaxes the 8.1C restrictions 982738032Speter slightly more. This includes proper setting of groups 982838032Speter when reading :include: files, allowing you to read some 982938032Speter files that you should be able to read but have previously 983038032Speter been denied unless you owned them or they had "other" 983138032Speter read permission. 983238032Speter Make certain that $j is in $=w (after the .cf is read) so that 983338032Speter if the user is forced to override some silly system, 983438032Speter MX suppression will still work. 983538032Speter Fix a couple of efficiency problems where newstr was double- 983638032Speter calling expensive routines. In at least one case, it 983738032Speter wasn't guaranteed that they would always return the 983838032Speter same result. Problem noted by Christophe Wolfhugel. 983938032Speter Fix null pointer dereference in putoutmsg -- only on an error 984038032Speter condition from a non-SMTP mailer. From Motonori 984138032Speter Nakamura. 984238032Speter Macro expand "C" line class definitions before scanning so that 984338032Speter "CX $Z" works. 984438032Speter Fix problem that caused error message to be sent while still 984538032Speter trying to send the original message if the connection 984638032Speter is closed during a DATA command after getting an error 984738032Speter on an RCPT command (pretty obscure). Problem reported 984838032Speter by John Myers of CMU. 984938032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 985038032Speter term bug. 985138032Speter Fix a nasty bug causing core dumps when returning the "warning: 985238032Speter cannot deliver for N hours -- will keep trying" message; 985343730Speter it only occurred if you had PostmasterCopy set and 985438032Speter only on some architectures. Although sendmail would 985538032Speter keep trying, it would send error messages on each 985638032Speter queue interval. This is an important fix. 985738032Speter Allow u and g options to take user and group names respectively. 985838032Speter Don't do a chdir into the queue directory in -bt mode to make 985938032Speter ruleset testing a bit easier. 986038032Speter Don't allow users to turn off logging (using -oL) on the command 986138032Speter line -- command line can only raise, not lower, logging 986238032Speter level. 986338032Speter Set $u to the original recipient on the SMTP transaction or on 986438032Speter the command line. This is only done if there is exactly 986538032Speter one recipient. Technically, this does not meet the 986638032Speter specs, because it does not guarantee a domain on the 986738032Speter address. 986838032Speter Fix a problem that dumped error messages on bad addresses if 986938032Speter you used the -t flag. Problem noted by Josh Smith of 987038032Speter Harvey Mudd College. 987138032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 987238032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 987338032Speter avoid the problem of people who use angle brackets in 987438032Speter their full name information. 987538032Speter Fix a null pointer dereference if you set option "l", have 987638032Speter an Errors-To: header in the message, and have Errors-To: 987738032Speter defined in the config file H lines. From J.R. Oldroyd. 987838032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 987938032Speter wrong when compiling. Suggested by Rick McCarty of TI. 988038032Speter Fix a problem that could pass negative SIZE parameter if the 988138032Speter df file got lost; this would cause servers to always 988238032Speter give a temporary failure, making the problem even worse. 988338032Speter Problem noted by Allan Johannesen of WPI. 988438032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 988538032Speter protocol timeouts (30s default). Requested by Murray 988638032Speter Kucherawy of HookUp Communication Corp. to handle bogus 988738032Speter PC TCP/IP implementations. 988838032Speter Change $w default definition to be just the first component of 988938032Speter the domain name on config level 5. The $j macro defaults 989038032Speter to the FQDN; $m remains as before. This lets well-behaved 989138032Speter config files use any of the short, long, or subdomain 989238032Speter names. 989338032Speter Add makesendmail script in src to try to automate multi-architecture 989438032Speter builds. I know, this is sub-optimal, but it is still 989538032Speter helpful. 989638032Speter Fix very obscure race condition that can cause a queue run to 989738032Speter get a queue file for an already completed job. This 989838032Speter problem has existed for years. Problem noted by the 989938032Speter long suffering Allan Johannesen of WPI. 990038032Speter Fix a problem that caused the raw sender name to be passed to 990138032Speter udbsender instead of the canonified name -- this caused 990238032Speter it to sometimes miss records that it should have found. 990338032Speter Relax check of name on HELO packet so that a program using -bs 990438032Speter that claims to be itself works properly. 990538032Speter Restore rewriting of $: part of address through 2, R, 4 in 990638032Speter buildaddr -- this requires passing a lot of flags to get 990738032Speter it right. Unlike old versions, this ONLY rewrites 990838032Speter recipient addresses, not sender addresses. 990938032Speter Fix a bug that caused core dumps in config files that cannot 991038032Speter resolve /file/name style addresses. Fix from Jonathan 991138032Speter Kamens of OpenVision Technologies. 991238032Speter Fix problem with fcntl locking that can cause error returns to 991338032Speter be lost if the lock is lost; this required fully 991438032Speter queueing everything, dropping the envelope (so errors 991538032Speter would get returned), and then re-reading the queue from 991638032Speter scratch. 991738032Speter Fix a problem that caused aliases that redefine an otherwise 991838032Speter true address to still send to the original address 991938032Speter if and only if the alias failed in certain bizarre 992038032Speter ways (e.g, if they pointed at a list:; syntax address). 992138032Speter Problem pointed out by Jonathan Kamens. 992238032Speter Remove support for frozen configuration files. They caused 992338032Speter more trouble than it was worth. 992438032Speter Fix problem that can cause error messages to get ignored when 992538032Speter using both -odb and -t flags. Problem noted by Rob 992638032Speter McNicholas at U.C. Berkeley. 992738032Speter Include all "normal" variations on hostname in $=w. For example, 992838032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 992938032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 993038032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 993138032Speter the queue. 993238032Speter Reset SmtpPhase global on initial connection creation so that 993338032Speter messages don't come out with stale information. 993438032Speter Pass an "ext" argument to lockfile so that error/log messages 993538032Speter will properly reflect the true filename being locked. 993638032Speter Put all [...] address forms into $=w -- this eliminates the need 993738032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 993838032Speter Myers of CMU. 993938032Speter Fix a bug that can cause qf files to be left around even after 994038032Speter an SMTP RSET command. Problem and fix from Michael 994138032Speter Corrigan. 994243730Speter Don't send a PostmasterCopy to errors when the Precedence: is 994338032Speter negative. Error reports still go to the envelope 994438032Speter sender address. 994538032Speter Add LA_SHORT for load averages. 994638032Speter Lock sendmail.st file when posting statistics. 994738032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 994838032Speter set the size of the TCP send and receive buffers; if you 994938032Speter run over a slow slip line you may need to set these down 995038032Speter (although it would be better to fix the SLIP implementation 995138032Speter so that it's not necessary to recompile every program 995238032Speter that does bulk data transfer). 995338032Speter Allow null defaults on $( ... $) lookups. Problem reported by 995438032Speter Amir Plivatsky. 995538032Speter Diagnose crufty S and V config lines. This resulted from an 995638032Speter observation that some people were using the SITE macro 995738032Speter without the SITECONFIG macro first, which was causing 995838032Speter bogus config files that were not caught. 995938032Speter Fix makemap -f flag to turn off case folding (it was turning it 996038032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 996138032Speter Fix a problem that caused multiple error messages to be sent if 996238032Speter you used "sendmail -t -oem -odb", your system uses fcntl 996338032Speter locking, and one of the recipient addresses is unknown. 996438032Speter Reset uid earlier in include() so that recursive .forwards or 996538032Speter :include:s don't use the wrong uid. 996638032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 996738032Speter called, the code to recover the descriptor was broken. 996838032Speter This sometimes (only sometimes) caused problems with the 996938032Speter alias file. Fix from Motonori Nakamura. 997038032Speter Fix a problem that caused aliaswait to go into infinite recursion 997138032Speter if the @:@ metasymbol wasn't found in the alias file. 997238032Speter Improve error message on newaliases if database files cannot be 997338032Speter opened or if running with no database format defined. 997438032Speter Do a better estimation of the size of error messages when NoReturn 997538032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 997638032Speter Fix a problem causing the "c" option (don't connect to expensive 997738032Speter mailers) to be ignored in SMTP. Problem noted and the 997838032Speter solution suggested by Robert Elz of The University of 997938032Speter Melbourne. 998038032Speter Improve connection caching algorithm by passing "[host]" to 998138032Speter hostsignature, which strips the square brackets and 998238032Speter returns the real name. This allows mailertable entries 998338032Speter to match regular entries. 998438032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 998538032Speter feature, even if it doesn't work right. 998638032Speter Catch and log attempts to try the "wiz" command in server SMTP. 998738032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 998838032Speter Be more generous at assigning $z to the home directory -- do this 998938032Speter for programs that are specified through a .forward file. 999038032Speter Fix from Andrew Chang of Sun Microsystems. 999138032Speter Always save a fatal error message in preference to a non-fatal 999238032Speter error message so that the "subject" line of return 999338032Speter messages is the best possible. 999438032Speter CONFIG: reduce the number of quotes needed to quote configuration 999538032Speter parameters with commas: two quotes should work now, e.g., 999638032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 999738032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 999838032Speter connections (domain-ized UUCP). 999938032Speter CONFIG: fix bug in default maps (-o must be before database file 1000064562Sgshapiro name). Pointed out by Christophe Wolfhugel. 1000138032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 1000238032Speter DNS. This would presumably be used in UUCP islands. 1000338032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 1000438032Speter CONFIG: log $u in Received: line. This is in technical violation 1000538032Speter of the standards, since it doesn't guarantee a domain 1000638032Speter on the address. 1000738032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 1000838032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 1000938032Speter the "m" flag should you want it. Apparently some Solaris 2.2 1001038032Speter installations can't handle multiple local recipients. 1001138032Speter Problem noted by Josh Smith. 1001238032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 1001338032Speter CONFIG: change default version level from 4 to 5. 1001438032Speter CONFIG: add FEATURE(nullclient) to create a config file that 1001538032Speter forwards all mail to a hub without ever looking at the 1001638032Speter addresses in any detail. 1001738032Speter CONFIG: properly strip mailer: information off of relays when 1001838032Speter used to change .BITNET form into %-hack form. 1001938032Speter CONFIG: fix a problem that caused infinite loops if presented 1002038032Speter with an address such as "!foo". 1002138032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 1002238032Speter the reverse "PTR" mapping is broken. There's a better 1002338032Speter way to do this, but the change is fairly major and I 1002438032Speter want to hold it for another release. Problem noted by 1002538032Speter Bret Marquis. 1002638032Speter 1002764562Sgshapiro8.5/8.5 1993/07/23 1002838032Speter Serious bug: if you used a command line recipient that was unknown 1002938032Speter sendmail would not send a return message (it was treating 1003038032Speter everything as though it had an SMTP-style client that 1003138032Speter would do the return itself). Problem noted by Josh Smith. 1003238032Speter Change "trymx" option in getcanonname() to ignore all MX data, 1003338032Speter even during a T_ANY query. This actually didn't break 1003438032Speter anything, because the only time you called getcanonname 1003538032Speter with !trymx was if you already knew there were no MX 1003638032Speter records, but it is somewhat cleaner. From Motonori 1003738032Speter Nakamura. 1003838032Speter Don't call getcanonname from getmxrr if you already know there 1003938032Speter are no DNS records matching the name. 1004038032Speter Fix a problem causing error messages to always include "The 1004138032Speter original message was received ... from localhost". 1004238032Speter The correct original host information is now included. 1004338032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 1004438032Speter version of "test" doesn't have the -x flag). Change it 1004538032Speter to use -f instead. From John Myers. 1004638032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 1004738032Speter esmtp -- it should be smtp. 1004838032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 1004938032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 1005038032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 1005138032Speter this cleans up the configs somewhat. This fixes a serious 1005238032Speter problem that caused route-addrs to get mistaken as relays, 1005338032Speter pointed out by John Myers. WARNING: this also causes 1005438032Speter the default on SMART_HOST to change from "suucp" to 1005538032Speter "relay" if you have MAILER(smtp) specified. 1005638032Speter 1005764562Sgshapiro8.4/8.4 1993/07/22 1005838032Speter Add option `w'. If you receive a message that comes to you because 1005938032Speter you are the best (lowest preference) target of an MX, and 1006038032Speter you haven't explicitly recognized the source MX host in 1006138032Speter your .cf file, this option will cause you to try the target 1006238032Speter host directly (as if there were no MX for it at all). If 1006338032Speter `w' is not set, this case is a configuration error. 1006438032Speter Beware: if `w' is set, senders may get bogus errors like 1006538032Speter "message timed out" or "host unknown" for problems that 1006638032Speter are really configuration errors. This option is 1006738032Speter disrecommended, provided only for compatibility with 1006838032Speter UIUC sendmail. 1006938032Speter Fix a problem that caused the incoming socket to be left open 1007038032Speter when sendmail forks after the DATA command. This caused 1007138032Speter calling systems to wait in FIN_WAIT_2 state until the 1007238032Speter entire list was processed and the child closed -- a 1007338032Speter potentially prodigious amount of time. Problem noted 1007438032Speter by Neil Rickert. 1007538032Speter Fix problem (created in 6.64) that caused mail sent to multiple 1007638032Speter addresses, one of which was a bad address, to completely 1007738032Speter suppress the sending of the message. This changes 1007838032Speter handling of EF_FATALERRS somewhat, and adds an 1007938032Speter EF_GLOBALERRS flag. This also fixes a potential problem 1008038032Speter with duplicate error messages if there is a syntax error 1008138032Speter in the header of a message that isn't noticed until late 1008238032Speter in processing. Original problem pointed out by Josh Smith 1008338032Speter of Harvey Mudd College. This release includes quite a bit 1008438032Speter of dickering with error handling (see below). 1008538032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 1008638032Speter will only hurt already-broken software and should help 1008738032Speter humans. 1008838032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 1008938032Speter compiled in. It would never read the alias file. 1009038032Speter Repair unbalanced `)' and `>' (the "open" versions are already 1009138032Speter repaired). 1009238032Speter Logging of "done" in dropenvelope() was incorrect: it would 1009338032Speter log this even when the queue file still existed. Change 1009438032Speter this to only log "done" (at log level 11) when the 1009538032Speter queue file is actually removed. From John Myers. 1009638032Speter Log "lost connection" in server SMTP at log level 20 if there 1009738032Speter is no pending transaction. Some senders just close the 1009838032Speter connection rather than sending QUIT. 1009938032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 1010038032Speter domains that do not have MX records -- this would cause 1010138032Speter the subsequent host name lookup to fail. The problem 1010238032Speter only occurred if you had FEATURE(nocanonify) set. 1010338032Speter Problem noted by Rick McCarty of Texas Instruments. 1010438032Speter Fix invocation of setvbuf when passed a -X flag -- I had 1010538032Speter unwittingly used an ANSI C extension, and this caused 1010638032Speter core dumps on some machines. 1010738032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 1010838032Speter Previously it just gave an empty send queue, which 1010938032Speter then gave either "Need RCPT (recipient)" at the DATA 1011038032Speter (confusing, since you had given an RCPT command which 1011138032Speter returned 250) or just dropped the email, depending on 1011238032Speter whether you were running VERBose mode. Now it usually 1011338032Speter diagnoses this case as "aliasing/forwarding loop broken". 1011438032Speter Unfortunately, it still doesn't adequately diagnose 1011538032Speter some true error conditions. 1011638032Speter Add internal concept of "warning messages" using 6xx codes. 1011738032Speter These are not reported only to Postmaster. Unbalanced 1011838032Speter parens, brackets, and quotes are printed as 653 codes. 1011938032Speter They are always mapped to 5xx codes before use in SMTP. 1012038032Speter Clean up error messages to tell both the actual address that 1012138032Speter failed and the alias they arose from. This makes it 1012238032Speter somewhat easier to diagnose problems. Difficulty noted 1012338032Speter by Motonori Nakamura. 1012438032Speter Fix a problem that inappropriately added a ctladdr to addresses 1012538032Speter that shouldn't have had one during a queue run. This 1012638032Speter caused error messages to be handled differently during 1012738032Speter a queue run than a direct run. 1012838032Speter Don't print the qf name and line number if you get errors during 1012938032Speter the direct run of the queue from srvrsmtp -- this was 1013038032Speter just extra stuff for users to crawl through. 1013138032Speter Put command line flags on second line of pid file so you can 1013238032Speter auto-restart the daemon with all appropriate arguments. 1013338032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1013438032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1013538032Speter restart it. 1013638032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1013738032Speter IDENT daemon to screw up. This required that I change 1013838032Speter HASSETEUID to HASSETREUID and complicate the mode 1013938032Speter changing somewhat because both Ultrix and SunOS seem 1014038032Speter to have a bug causing seteuid() to set the saved uid 1014138032Speter as well as the effective. The program test/t_setreuid.c 1014238032Speter will test to see if your implementation of setreuid(2) 1014338032Speter is appropriately functional. 1014438032Speter The FallBackMX (option V) handling failed to properly identify 1014538032Speter fallback to yourself -- most of the code was there, 1014638032Speter but it wasn't being enabled. Problem noted by Murray 1014738032Speter Kucherawy of the University of Waterloo. 1014838032Speter Change :include: open timeout from ETIMEDOUT to an internal 1014938032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1015038032Speter with CurHostName" in error messages, which can be 1015138032Speter confusing. Reported by Jonathan Kamens of OpenVision 1015238032Speter Technologies. 1015338032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1015438032Speter process group id. The original fix was to get around 1015538032Speter some problems with recalcitrant MUAs, but it breaks 1015638032Speter any call from a shell that creates a process group id 1015738032Speter different from the process id. I could try to fix 1015838032Speter this by diddling the tty owner (using tcsetpgrp or 1015938032Speter equivalent) but this is too likely to break other 1016038032Speter things. 1016138032Speter Portability changes: 1016238032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1016338032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1016438032Speter instead of using standard flags. Oh joy. This 1016543730Speter behavior reported by Jon Giltner of University 1016638032Speter of Colorado. 1016738032Speter SGI IRIX -- this includes several changes that should 1016838032Speter help other strict ANSI compilers. 1016938032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1017038032Speter Corporation. 1017138032Speter Solaris running the Sun C compiler (which despite the 1017238032Speter documentation apparently doesn't define 1017338032Speter __STDC__ by default). 1017438032Speter ConvexOS from Eric Schnoebelen of Convex. 1017538032Speter Sony NEWS workstations and Omron LUNA workstations from 1017638032Speter Motonori Nakamura. 1017738032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1017838032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1017938032Speter several people have made a good argument that this 1018038032Speter creates more problems than it solves (although this 1018138032Speter may prove painful in the short run). 1018238032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1018338032Speter format. 1018438032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1018538032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1018638032Speter addresses are also passed through this ruleset. 1018738032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1018838032Speter internet-style addresses would "fall off the end" of 1018938032Speter ruleset zero and be interpreted as local -- however, 1019038032Speter the angle brackets confused the recursive call. 1019138032Speter These are now diagnosed as "Unrecognized host name". 1019238032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1019338032Speter ifdef(`_MAILER_USENET_') instead of 1019438032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1019538032Speter of SINTEF RUNIT, Oslo. 1019638032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1019738032Speter early in ruleset 0; this allows .mc authors to bypass 1019838032Speter things like the "short circuit" code for local addresses. 1019938032Speter Prompted by a comment by Bill Wisner of The Well. 1020038032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1020138032Speter esmtp) to send SMTP mail. This allows you to default 1020238032Speter to esmtp but use a mailertable or other override to 1020338032Speter deal with broken servers. This logic was pointed out 1020438032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1020538032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1020638032Speter environments. Ugly as sin. 1020738032Speter 1020864562Sgshapiro8.3/8.3 1993/07/13 1020938032Speter Fix setuid problems introduced in 8.2 that caused messages 1021038032Speter like "Cannot create qfXXXXXX: Invalid argument" 1021138032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1021238032Speter involved a new compile flag "HASSETEUID" that takes 1021338032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1021438032Speter that the POSIX interface is broken enough to break 1021538032Speter some systems badly. This includes some fixes for 1021638032Speter HP-UX. Also fixes problems where the real uid is 1021738032Speter not reset properly on startup (from Neil Rickert). 1021838032Speter Fix a problem that caused timed out messages to not report the 1021938032Speter addresses that timed out. Error messages are also more 1022038032Speter "user friendly". 1022138032Speter Drop required bandwidth on connections from 64 bytes/sec to 1022238032Speter 16 bytes/sec. 1022338032Speter Further Solaris portability changes -- doesn't require the BSD 1022438032Speter compatibility library. This also adds a new 1022538032Speter "HASGETDTABLESIZE" compile flag which can be used if 1022638032Speter you want to use getdtablesize(2) instead of sysconf(2). 1022738032Speter These are loosely based on changes from David Meyer at 1022838032Speter University of Oregon. This now seems to work, at least 1022938032Speter for quick test cases. 1023038032Speter Fix a problem that can cause duplicate error messages to be 1023138032Speter sent if you are in SMTP, you send to multiple addresses, 1023238032Speter and at least one of those addresses is good and points 1023338032Speter to an account that has a .forward file (whew!). 1023438032Speter Fix a problem causing messages to be discarded if checkcompat() 1023538032Speter returned EX_TEMPFAIL (because it didn't properly mark 1023638032Speter the "to" address). Problem noted by John Myers. 1023738032Speter Fix dfopen to return NULL if the open failed; I was depending 1023838032Speter on fdopen(-1) returning NULL, which isn't the case. This 1023938032Speter isn't serious, but does result in weird error diagnoses. 1024038032Speter From Michael Corrigan. 1024138032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1024238032Speter messages sent through UUCP-family mailers. Suggested 1024338032Speter by Bill Wisner of The Well. 1024438032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1024538032Speter include a "uucp-dom" mailer that uses domain-style 1024638032Speter addressing. Suggested by Bill Wisner. 1024738032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1024838032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1024938032Speter Christophe Wolfhugel. 1025038032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1025138032Speter 1025264562Sgshapiro8.2/8.2 1993/07/11 1025338032Speter Don't drop out on config file parse errors in -bt mode. 1025438032Speter On older configuration files, assume option "l" (use Errors-To 1025538032Speter header) for back compatibility. NOTE: this DOES NOT 1025638032Speter imply an endorsement of the Errors-To: header in any way. 1025738032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1025838032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1025938032Speter SMTP server to give an error on this command, and 1026038032Speter logging it in the transcript can be confusing. Fix 1026138032Speter from Bill Wisner. 1026238032Speter IRIX compatibility changes provided by Dan Rich 1026338032Speter <drich@sandman.lerc.nasa.gov>. 1026438032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1026538032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1026638032Speter <juo@klinzhai.rutgers.edu> 1026738032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1026838032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1026938032Speter match the other flags in that file. 1027038032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1027138032Speter Save h_errno in mci struct and improve error message display. 1027238032Speter Changes from Eric Wassenaar. 1027338032Speter Open /dev/null for the transcript if the create of the xf file 1027438032Speter failed; this avoids at least one possible null pointer 1027538032Speter reference in very weird cases. From Eric Wassenaar. 1027638032Speter Clean up statistics gathering; it was over-reporting because of 1027738032Speter forks. From Eric Wassenaar. 1027838032Speter Fix problem that causes old Return-Path: line to override new 1027938032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1028038032Speter re-using old value). From Motonori Nakamura. 1028138032Speter Fix broken -m flag in K definition -- even if -m (match only) 1028238032Speter was specified, it would still replace the key with the 1028338032Speter value. Noted by Rick McCarty of Texas Instruments. 1028438032Speter If the name server timed out over several days, no "timed out" 1028538032Speter message would ever be sent back. The timeout code 1028638032Speter has been moved from markfailure() to dropenvelope() 1028738032Speter so that all such failures should be diagnosed. Pointed 1028838032Speter out by Christophe Wolfhugel and others. 1028938032Speter Relax safefile() constraints: directories in an include or 1029038032Speter forward path must be readable by self if the controlling 1029138032Speter user owns the entry, readable by all otherwise (e.g., 1029238032Speter when reading your .forward file, you have to own and 1029338032Speter have X permission in it; everyone needs X permission in 1029438032Speter the root and directories leading up to your home); 1029538032Speter include files must be readable by anyone, but need not 1029638032Speter be owned by you. 1029738032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1029838032Speter reading a .forward file; this gets around some problems 1029938032Speter on NFS mounts if root permission is not exported and 1030038032Speter the user's home directory isn't x'able. 1030138032Speter Additional NeXT portability enhancements from Axel Zinser. 1030238032Speter Additional HP-UX portability enhancements from Brian Bullen. 1030338032Speter Add a timeout around SMTP message writes; this assumes you can 1030438032Speter get throughput of at least 64 bytes/second. Note that 1030538032Speter this does not impact the "datafinal" default, which 1030638032Speter is separate; this is just intended to work around 1030738032Speter network clogs that will occur before the final dot 1030838032Speter is sent. From Eric Wassenaar. 1030938032Speter Change map code to set the "include null" flag adaptively -- 1031038032Speter it initially tries both, but if it finds anything 1031138032Speter matching without a null it never tries again with a 1031238032Speter null and vice versa. If -N is specified, it never 1031338032Speter tries without the null and creates new maps with a 1031438032Speter null byte. If -O is specified, it never tries with 1031538032Speter the null (for efficiency). If -N and -O are specified, 1031638032Speter you get -NO (get it?) lookup at all, so this would 1031738032Speter be a bad idea. If you don't specify either -N or -O, 1031838032Speter it adapts. 1031938032Speter Fix recognition of "same from address" so that MH submissions 1032038032Speter will insert the appropriate full name information; 1032138032Speter this used to work and got broken somewhere along the 1032238032Speter way. 1032338032Speter Some changes to eliminate some unnecessary SYSERRs in the 1032438032Speter log. For example, if you lost a connection, don't 1032538032Speter bother reporting that fact on the connection you lost. 1032638032Speter Add some "extended debugging" flags to try to track down 1032738032Speter why we get occasional problems with file descriptor 1032838032Speter one being closed when execing a mailer; it seems to 1032938032Speter only happen when there has been another error in the 1033038032Speter same transaction. This requires XDEBUG, defined 1033138032Speter by default in conf.h. 1033238032Speter Add "-X filename" command line flag, which logs both sides of 1033338032Speter all SMTP transactions. This is intended ONLY for 1033438032Speter debugging bad implementations of other mailers; start 1033538032Speter it up, send a message from a mailer that is failing, 1033638032Speter and then kill it off and examine the indicated log. 1033738032Speter This output is not intended to be particularly human 1033838032Speter readable. This also adds the HASSETVBUF compile 1033938032Speter flag, defaulted on if your compiler defines __STDC__. 1034038032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1034138032Speter have a local net that should get direct connects, you 1034238032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1034338032Speter See cf/README for an example. 1034438032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1034538032Speter sites that don't use the -d flag. 1034638032Speter CONFIG: hide recipient addresses as well as sender addresses 1034738032Speter behind $M if FEATURE(allmasquerade) is specified; this 1034838032Speter has been requested by several people, but can break 1034938032Speter local aliases. For example, if you mail to "localalias" 1035038032Speter this will be rewritten as "localalias@masqueradehost"; 1035138032Speter although initial delivery will work, replies will be 1035238032Speter broken. Use it sparingly. 1035338032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1035438032Speter to qualified domains in headers. I believe this is 1035538032Speter largely equivalent to the IDA feature of the same name. 1035638032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1035738032Speter to override the "system name" as your UUCP name -- 1035838032Speter in particular, to use domain-ized UUCP names. From 1035938032Speter Bill Wisner of The Well. 1036038032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1036138032Speter first. This is currently unused in the config files, 1036238032Speter but could be used in a mailertable entry. 1036338032Speter 1036464562Sgshapiro8.1C/8.1B 1993/06/27 1036538032Speter Serious security bug fix: it was possible to read any file on 1036638032Speter the system, regardless of ownership and permissions. 1036738032Speter If a subroutine returns a fully qualified address, return it 1036838032Speter immediately instead of feeding it back into rewriting. 1036938032Speter This fixes a problem with mailertable lookups. 1037038032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1037138032Speter 1037264562Sgshapiro8.1B/8.1A 1993/06/12 1037338032Speter Serious bug fix: pattern matching backup algorithm stepped by 1037438032Speter two tokens in classes instead of one. Found by Claus 1037538032Speter Assmann at University of Kiel, Germany. 1037638032Speter 1037764562Sgshapiro8.1A/8.1A 1993/06/08 1037838032Speter Another mailertable fix.... 1037938032Speter 1038064562Sgshapiro8.1/8.1 1993/06/07 1038138032Speter 4.4BSD freeze.
