Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.53
+-----------------
+
+TK/01 Added the "success_on_redirect" address verification option. 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.
+
Exim version 4.52
-----------------
"%lld" and "long long". Replaced the call to snprintf() with a call to
string_vformat().
-PH/21 Added another message to those in 4.51/PH/42, namely "All relevant MX
- records point to non-existent hosts".
+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<list> and the -show_dt<list> 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
