See + NewStuff for rationale and an example. + +PH/01 Added support for SQLite, basic code supplied by David Woodhouse. + +PH/02 Patch to exigrep to allow it to work on syslog lines. + +PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of + fread() to skip over the body file's header line, because in Cygwin the + header line is locked and is inaccessible. + +PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both + co-exist for some time) to make it clear that it is the Exim ID that is + referenced, not the Message-ID: header line. + +PH/05 Replaced all Tom's calls to snprintf() with calls to the internal + string_format() function, because snprintf() does not exist on all + operating systems. + +PH/06 The use of forbid_filter_existstest now also locks out the use of the + ${stat: expansion item. + +PH/07 Changed "SMTP protocol violation: synchronization error" into "SMTP + protocol synchronization error", to keep the pedants happy. + +PH/08 Arrange for USE_INET_NTOA_FIX to be set in config.h for AIX systems as + well as for IRIX systems, when gcc is being used. See the host.c source + file for comments. + +PH/09 Installed latest Cygwin configuration files from the Cygwin maintainer. + +PH/10 Named domain lists were not working if used in a queue_smtp_domains + setting. + +PH/11 Added support for the IGNOREQUOTA extension to LMTP, both to the lmtp + transport and to the smtp transport in LMTP mode. + +TK/02 Remove one case of BASE64 error detection FTTB (undocumented anyway). + +PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to + run a filter in a subprocess. This could lead to confusion in subsequent + lookups in the parent process. There should also be a search_tidyup() at + the end of the subprocess. + +PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true + only if the host matched helo_try_verify_hosts, which caused the + verification to occur when the EHLO/HELO command was issued. The ACL just + tested the remembered result. Now, if a previous verification attempt has + not happened, "verify = helo" does it there and then. + +JJ/01 exipick: added $message_exim_id variable (see 4.53-PH/04) + +TK/03 Fix log output including CR from clamd. + +PH/14 A reference to $reply_address when Reply-to: was empty and From: did not + exist provoked a memory error which could cause a segfault. + +PH/15 Installed PCRE 6.2 + +PH/17 Defined BIND_8_COMPAT in the Darwin os.h file. + +PH/18 Reversed 4.52/PH/17 because the HP-UX user found it wasn't the cause + of the problem. Specifically, suggested +O2 rather than +O1 for the + HP-UX compiler. + +PH/19 Added sqlite_lock_timeout option (David Woodhouse's patch). + +PH/20 If a delivery was routed to a non-standard port by means of an SRV + record, the port was not correctly logged when the outgoing_port log + selector was set (it logged the transort's default port). + +PH/21 Added support for host-specific ports to manualroute, queryprogram, + fallback_hosts, and "hosts" in the smtp transport. + +PH/22 If the log selector "outgoing_port" is set, the port is now also given on + host errors such as "Connection refused". + +PH/23 Applied a patch to fix problems with exim-4.52 while doing radius + authentication with radiusclient 0.4.9: + + - Error returned from rc_read_config was caught wrongly + - Username/password not passed on to radius server due to wrong length. + + The presumption is that some radiusclient API changes for 4.51/PH/17 + were not taken care of correctly. The code is still untested by me (my + Linux distribution still has 0.3.2 of radiusclient), but it was + contributed by a Radius user. + +PH/24 When doing a callout, the value of $domain wasn't set correctly when + expanding the "port" option of the smtp transport. + +TK/04 MIME ACL: Fix buffer underrun that occurs when EOF condition is met + while reading a MIME header. Thanks to Tom Hughes for a patch. + +PH/24 Include config.h inside local_scan.h so that configuration settings are + available. + +PH/25 Make $smtp_command_argument available after all SMTP commands. This means + that in an ACL for RCPT (for example), you can examine exactly what was + received. + +PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO + commands, but it was not correctly comparing the address with the actual + client host address. Thus, it would show the EHLO address in Received: + header lines when this was not necessary. + +PH/27 Added the % operator to ${eval:}. + +PH/28 Exim tries to create and chdir to its spool directory when it starts; + it should be ignoring failures (because with -C, for example, it has lost + privilege). It wasn't ignoring creation failures other than "already + exists". + +PH/29 Added "crypteq" to the list of supported features that Exim outputs when + -bV or -d is used. + +PH/30 Fixed (presumably very longstanding) bug in exim_dbmbuild: if it failed + because an input line was too long, either on its own, or by virtue of + too many continuations, the temporary file was not being removed, and the + return code was incorrect. + +PH/31 Missing "BOOL" in function definition in filtertest.c. + +PH/32 Applied Sieve patches from the maintainer. + +TK/05 Domainkeys: Accomodate for a minor API change in libdomainkeys 0.67. + +PH/33 Added "verify = not_blind". + +PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in + Local/Makefile (with some defaults set). These are used in built scripts + such as exicyclog, but they have never been used in the exim_install + script (though there are many overriding facilities there). I have + arranged that the exim_install script now takes note of these two + settings. + +PH/35 Installed configuration files for Dragonfly. + +PH/36 When a locally submitted message by a trusted user did not contain a + From: header, and the sender address was obtained from -f or from an SMTP + MAIL command, and the trusted user did not use -F to supply a sender + name, $originator_name was incorrectly used when constructing a From: + header. Furthermore, $originator_name was used for submission mode + messages from external hosts without From: headers in a similar way, + which is clearly wrong. + +PH/37 Added control=suppress_local_fixups. + +PH/38 When log_selector = +received_sender was set, and the addition of the + sender made the log line's construction buffer exactly full, or one byte + less than full, an overflow happened when the terminating "\n" was + subsequently added. + +PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry + when the result of a list match is failure because a DNS lookup failed. + +PH/40 RM_COMMAND is now used in the building process. + +PH/41 Added a "distclean" target to the top-level Makefile; it deletes all + the "build-* directories that it finds. + +PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP + address in a domain literal was a prefix of an interface address. + +PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains + when verifying a sender address, unless rewrite_headers is false. + +PH/44 Wrote a long comment about why errors_to addresses are verified as + recipients, not senders. + +TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when + the ratelimit ACL was added. + + +Exim version 4.52 +----------------- + +TF/01 Added support for Client SMTP Authorization. See NewStuff for details. + +PH/01 When a transport filter timed out in a pipe delivery, and the pipe + command itself ended in error, the underlying message about the transport + filter timeout was being overwritten with the pipe command error. Now the + underlying error message should be appended to the second error message. + +TK/01 Fix poll() being unavailable on Mac OSX 10.2. + +PH/02 Reduce the amount of output that "make" produces by default. Full output + can still be requested. + +PH/03 The warning log line about a condition test deferring for a "warn" verb + was being output only once per connection, rather than after each + occurrence (because it was using the same function as for successful + "warn" verbs). This seems wrong, so I have changed it. + +TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that + it should not have, which might have caused a crash in the right + circumstances, but probably never did. + +PH/04 Installed a modified version of Tony Finch's patch to make submission + mode fix the return path as well as the Sender: header line, and to + add a /name= option so that you can make the user's friendly name appear + in the header line. + +TF/03 Added the control = fakedefer ACL modifier. + +TF/04 Added the ratelimit ACL condition. See NewStuff for details. Thanks to + Mark Lowes for thorough testing. + +TK/02 Rewrote SPF support to work with libspf2 versions >1.2.0. + +TK/03 Merged latest SRS patch from Miles Wilton. + +PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts + with the definition in sysexits.h (which is #included earlier). + Fortunately, Exim does not actually use EX_OK. The code used to try to + preserve the sysexits.h value, by assumimg that macro definitions were + scanned for macro replacements. I have been disabused of this notion, + so now the code just undefines EX_OK before #including unistd.h. + +PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout + in the smtp transport. When a block could not be written in a single + write() function, the timeout was being re-applied to each part-write. + This seems wrong - if the receiver was accepting one byte at a time it + would take for ever. The timeout is now adjusted when this happens. It + doesn't have to be particularly precise. + +TK/04 Added simple SPF lookup method in EXPERIMENTAL_SPF. See NewStuff for + details. Thanks to Chris Webb for the patch! + +PH/07 Added "fullpostmaster" verify option, which does a check to + without a domain if the check to fails. + +SC/01 Eximstats: added -xls and the ability to specify output files + (patch written by Frank Heydlauf). + +SC/02 Eximstats: use FileHandles for outputing results. + +SC/03 Eximstats: allow any combination of xls, txt, and html output. + +SC/04 Eximstats: fixed display of large numbers with -nvr option + +SC/05 Eximstats: fixed merging of reports with empty tables. + +SC/06 Eximstats: added the -include_original_destination flag + +SC/07 Eximstats: removed tabs and trailing whitespace. + +TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller. + +TK/06 MBOX spool code: Add real "From " MBOX separator line + so the .eml file is really in mbox format (even though + most programs do not really care). Patch from Alex Miller. + +TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers. + The latter is generated from $received_to and is only set if the + message has one envelope recipient. SA can use these headers, + obviously out-of-the-box. Patch from Alex Miller. + +PH/08 The ${def test on a variable was returning false if the variable's + value was "0", contrary to what the specification has always said! + The result should be true unless the variable is empty. + +PH/09 The syntax error of a character other than { following "${if + def:variable_name" (after optional whitespace) was not being diagnosed. + An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an + accidental colon was present, for example, could give incorrect results. + +PH/10 Tidied the code in a number of places where the st_size field of a stat() + result is used (not including appendfile, where other changes are about + to be made). + +PH/11 Upgraded appendfile so that quotas larger than 2G are now supported. + This involved changing a lot of size variables from int to off_t. It + should work with maildirs and everything. + +TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of + spamd dying while we are connected to it. + +TF/05 Fixed a ${extract error message typo reported by Jeremy Harris + + +PH/12 Applied Alex Kiernan's patch for the API change for the error callback + function for BDB 4.3. + +PH/13 Changed auto_thaw such that it does not apply to bounce messages. + +PH/14 Imported PCRE 6.0; this was more than just a trivial operation because + the sources for PCRE have been re-arranged and more files are now + involved. + +PH/15 The code I had for printing potentially long long variables in PH/11 + above was not the best (it lost precision). The length of off_t variables + is now inspected at build time, and an appropriate printing format (%ld + or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T + to be "long long int" or "long int". This is needed for the internal + formatting function string_vformat(). + +PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in + the configuration file to be ":syslog", then the script "guesses" where + the logs files are, rather than using the compiled in default. In our + case the guess is not the same as the compiled default, so the script + suddenly stopped working when I started to use syslog. The patch checks + to see if log_file_path is "". If so, it attempts to read it from exim + with no configuration file to get the compiled in version, before it + falls back to the previous guessing code." + +TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with + implementing BATV in an Exim configuration. See NewStuff for the gory + details. + +PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and + Makefile that are specific to HP-UX. + +PH/18 If the "use_postmaster" option was set for a recipient callout together + with the "random" option, the postmaster address was used as the MAIL + FROM address for the random test, but not for the subsequent recipient + test. It is now used for both. + +PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The + patch removes a few documentation additions to RFC 3028, because the + latest draft now contains them. It adds the new en;ascii-case comparator + and a new error check for 8bit text in MIME parts. Comparator and + require names are now matched exactly. I enabled the subaddress + extension, but it is not well tested yet (read: it works for me)." + +PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to + rework some of the code of TK/09 above to avoid the hardwired use of + "%lld" and "long long". Replaced the call to snprintf() with a call to + string_vformat(). + +PH/21 Added some other messages to those in 4.51/PH/42, namely "All relevant MX + records point to non-existent hosts", "retry timeout exceeded", and + "retry time not reached for any host after a long failure period". + +PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with + experimental DomainKeys support: + + (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken. + (2) On an error such as an illegally used "control", the wrong name for + the control was given. + + These problems did NOT occur unless DomainKeys support was compiled. + +PH/23 Added daemon_startup_retries and daemon_startup_sleep. + +PH/24 Added ${if match_ip condition. + +PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints + databases so that it will be absolutely obvious if a crash occurs in the + DB library. This is a regular occurrence (often caused by mis-matched + db.h files). + +PH/26 Insert a lot of missing (void) casts for functions such as chown(), + chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were + picked up on a user's system that detects such things. There doesn't seem + to be a gcc warning option for this - only an attribute that has to be + put on the function's prototype. It seems that in Fedora Core 4 they have + set this on a number of new functions. No doubt there will be more in due + course. + +PH/27 If a dnslookup or manualroute router is set with verify=only, it need not + specify a transport. However, if an address that was verified by such a + router was the subject of a callout, Exim crashed because it tried to + read the rcpt_include_affixes from the non-existent transport. Now it + just assumes that the setting of that option is false. This bug was + introduced by 4.51/PH/31. + +PH/28 Changed -d+all to exclude +memory, because that information is very + rarely of interest, but it makes the output a lot bigger. People tend to + do -d+all out of habit. + +PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the + code in os-type was giving problems when libc.so lives in lib64, like on + x86_64 Fedora Core. + +PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These + aren't the modern standard, and it seems that some systems' include files + don't always have them. Exim was already checking for some of the newer + ones like T_AAAA, and defining it itself. I've added checks for all the + record types that Exim uses. + +PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was + not automatically generating a new one, as it is supposed to. This + prevented TLS from working. If the file did exist, but contained invalid + data, a new version was generated, as expected. It was only the case of a + non-existent file that was broken. + +TK/10 Domainkeys: Fix a bug in verification that caused a crash in conjunction + with a change in libdomainkeys > 0.64. + +TK/11 Domainkeys: Change the logic how the "testing" policy flag is retrieved + from DNS. If the selector record carries the flag, it now has + precedence over the domain-wide flag. + +TK/12 Cleared some compiler warnings related to SPF, SRS and DK code. + +PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as + the use of a port name that isn't defined in /etc/services) occurred, the + message was deferred as in a normal delivery, and thus remained on the + spool, instead of being failed because of the mua_wrapper setting. This + is now fixed, and I tidied up some of the mua_wrapper messages at the + same time. + +SC/08 Eximstats: whilst parsing the mainlog(s), store information about + the messages in a hash of arrays rather than using individual hashes. + This is a bit cleaner and results in dramatic memory savings, albeit + at a slight CPU cost. + +SC/09 Eximstats: added the -show_rt and the -show_dt flags + as requested by Marc Sherman. + +SC/10 Eximstats: added histograms for user specified patterns as requested + by Marc Sherman. + +SC/11 Eximstats: v1.43 - bugfix for pattern histograms with -h0 specified. + +PH/33 Patch from the Cygwin maintainer to add "b" to all occurences of + fopen() in the content-scanning modules that did not already have it. + Exim version 4.51 ----------------- @@ -270,6 +692,23 @@ PH/44 Applied patch from the Sieve maintainer: "The vacation draft is still being worked on, but at least Exim now implements the latest version to play with." +PH/45 In a pipe transport, although a timeout while waiting for the pipe + process to complete was treated as a delivery failure, a timeout while + writing the message to the pipe was logged, but erroneously treated as a + successful delivery. Such timeouts include transport filter timeouts. For + consistency with the overall process timeout, these timeouts are now + treated as errors, giving rise to delivery failures by default. However, + there is now a new Boolean option for the pipe transport called + timeout_defer, which, if set TRUE, converts the failures into defers for + both kinds of timeout. A transport filter timeout is now identified in + the log output. + +PH/46 The "scripts/Configure-config.h" script calls "make" at one point. On + systems where "make" and "gmake" are different, calling "gmake" at top + level broke things. I've arranged for the value of $(MAKE) to be passed + from the Makefile to this script so that it can call the same version of + "make". + A note about Exim versions 4.44 and 4.50 ----------------------------------------
