Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.51
+-----------------
+
+TK/01 Added Yahoo DomainKeys support via libdomainkeys. See
+ doc/experimental-spec.txt for details. (http://domainkeys.sf.net)
+
+TK/02 Fix ACL "control" statement not being available in MIME ACL.
+
+TK/03 Fix ACL "regex" condition not being available in MIME ACL.
+
+PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
+ to test Sieve filters that use "vacation".
+
+PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
+ that changes the way the GnuTLS parameters are stored in the cache file.
+ The new format can be generated externally. For backward compatibility,
+ if the data in the cache doesn't make sense, Exim assumes it has read an
+ old-format file, and it generates new data and writes a new file. This
+ means that you can't go back to an older release without removing the
+ file.
+
+PH/03 A redirect router that has both "unseen" and "one_time" set does not
+ work if there are any delivery delays because "one_time" forces the
+ parent to be marked "delivered", so its unseen clone is never tried
+ again. For this reason, Exim now forbids the simultaneous setting of
+ these two options.
+
+PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
+ redirected to themselves ("homonym" addresses). Read the long ChangeLog
+ entry if you want to know the details. The fix, however, neglected to
+ consider the case when local delivery batching is involved. The test for
+ "previously delivered" was not happening when checking to see if an
+ address could be batched with a previous (undelivered) one; under
+ certain circumstances this could lead to multiple deliveries to the same
+ address. A one-line patch to add the appropriate test fixes the bug.
+
+PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
+ in its include files, and this causes problems building Exim.
+
+PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
+ header_syntax) but Exim was just ignoring anything given after a slash.
+ In particular, this caused confusion with an attempt to use "verify =
+ reverse_host_lookup/defer_ok". An error is now given when options are
+ supplied for verify items that do not have them. (Maybe reverse_host_
+ lookup should have a defer_ok option, but that's a different point.)
+
+PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
+ defined by RFC 821) to 2048, because there were problems with some AUTH
+ commands, and RFC 1869 says the size should be increased for extended
+ SMTP commands that take arguments.
+
+PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
+ Finch).
+
+PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an
+ "unknown" error; now it says that the functionality isn't in the binary.
+
+PH/10 Added a nasty fudge to try to recognize and flatten LDAP passwords in
+ an address' error message when a string expansion fails (syntax or
+ whatever). Otherwise not only does the password appear in the log, it may
+ also be put in a bounce message.
+
+PH/11 Installed exipick version 20050225.0 from John Jetmore.
+
+PH/12 If the last host in a fallback_hosts list was multihomed, only the first
+ of its addresses was ever tried. (Bugzilla bug #2.)
+
+PH/13 If "headers_add" in a transport didn't end in a newline, Exim printed
+ the result incorrectly in the debug output. (It correctly added a newline
+ to what was transported.)
+
+TF/01 Added $received_time.
+
+PH/14 Modified the default configuration to add an acl_smtp_data ACL, with
+ commented out examples of how to interface to a virus scanner and to
+ SpamAssassin. Also added commented examples of av_scanner and
+ spamd_address settings.
+
+PH/15 Further to TK/02 and TK/03 above, tidied up the tables of what conditions
+ and controls are allowed in which ACLs. There were a couple of minor
+ errors. Some of the entries in the conditions table (which is a table of
+ where they are NOT allowed) were getting very unwieldy; rewrote them as a
+ negation of where the condition IS allowed.
+
+PH/16 Installed updated OS/os.c-cygwin from the Cygwin maintainer.
+
+
A note about Exim versions 4.44 and 4.50
----------------------------------------
error if it is another Exim or anything else that does the synchronization
check. A QUIT command is no longer sent after a timeout.
+73. $host_lookup_deferred has been added, to make it easier to detect DEFERs
+ during host lookups.
+
+74. The defer_ok option of callout verification was not working if it was used
+ when verifying addresses in header lines, that is, for this case:
+
+ verify = header_sender/callout=defer_ok
+
+75. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
+ those file descriptors could be used for SMTP connections. If anything
+ wrote to stderr (the example that came up was "warn" in embedded Perl), it
+ could be sent to the SMTP client, causing chaos. The daemon now opens
+ stdin, stdout, and stderr to /dev/null when it puts itself into the
+ background.
+
+76. Arrange for output from Perl's "warn" command to be written to Exim's main
+ log by default. The user can override this with suitable Perl magic.
+
+77. The use of log_message on a "discard" ACL verb, which is supposed to add to
+ the log message when discard triggers, was not working for the DATA ACL or
+ for the non-SMTP ACL.
+
+78. Error message wording change in sieve.c.
+
+79. If smtp_accept_max_per_host was set, the number of connections could be
+ restricted to fewer than expected, because the daemon was trying to set up
+ a new connection before checking whether the processes handling previous
+ connections had finished. The check for completed processes is now done
+ earlier. On busy systems, this bug wouldn't be noticed because something
+ else would have woken the daemon, and it would have reaped the completed
+ process earlier.
+
+80. If a message was submitted locally by a user whose login name contained one
+ or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
+ It caused a spool format error. I have fixed the spool reading code. A
+ related problem was that the "from" clause in the Received: line became
+ illegal because of the space(s). It is now covered by ${quote_local_part.
+
+81. Included the latest eximstats from Steve (adds average sizes to HTML Top
+ tables).
+
+82. Updated OS/Makefile-AIX as per message from Mike Meredith.
+
+83. Patch from Sieve maintainer to fix unterminated string problem in
+ "vacation" handling.
+
+84. Some minor changes to the Linux configuration files to help with other
+ OS variants using glibc.
+
+85. One more patch for Sieve to update vacation handling to latest spec.
