Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.61
+-----------------
+
+PH/01 The code for finding all the local interface addresses on a FreeBSD
+ system running IPv6 was broken. This may well have applied to all BSD
+ systems, as well as to others that have similar system calls. The broken
+ code found IPv4 interfaces correctly, but gave incorrect values for the
+ IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
+ that it would not match correctly against @[] and not recognize the IPv6
+ addresses as local.
+
+PH/02 The ipliteral router was not recognizing addresses of the form user@
+ [ipv6:....] because it didn't know about the "ipv6:" prefix.
+
+PH/03 Added disable_ipv6.
+
+PH/04 Changed $reply_address to use the raw form of the headers instead of the
+ decoded form, because it is most often used to construct To: headers
+ lines in autoreplies, and the decoded form may well be syntactically
+ invalid. However, $reply_address has leading white space removed, and all
+ newlines turned into spaces so that the autoreply transport does not
+ grumble.
+
+PH/05 If group was specified without a user on a router, and no group or user
+ was specified on a transport, the group from the router was ignored.
+
+PH/06 Increased the number of ACL variables to 20 of each type, and arranged
+ for visible compile-time settings that can be used to change these
+ numbers, for those that want even more. Backwards compatibility with old
+ spool files has been maintained. However, going back to a previous Exim
+ release will lost any variables that are in spool files.
+
+PH/07 Two small changes when running in the test harness: increase delay when
+ passing a TCP/IP connection to a new process, in case the original
+ process has to generate a bounce, and remove special handling of
+ 127.0.0.2 (sic), which is no longer necessary.
+
+PH/08 Changed debug output of dbfn_open() flags from numbers to names, so as to
+ be the same on different OS.
+
+PH/09 Moved a debug statement in filter processing to avoid a race problem when
+ testing.
+
+JJ/01 exipick: fixed bug where -b (brief) output option showed "Vars:"
+ whether --show-vars was specified or not
+
+JJ/02 exipick: Added support for new ACL variable spool format introduced
+ in 4.61-PH/06
+
+PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
+ syntactically invalid From: or Reply-to: line, and a filter used this to
+ generate an autoreply, and therefore failed to obtain an address for the
+ autoreply, Exim could try to deliver to a non-existent relative file
+ name, causing unrelated and misleading errors. What now happens is that
+ it logs this as a hard delivery error, but does not attempt to create a
+ bounce message.
+
+PH/11 The exinext utility has a -C option for testing purposes, but although
+ the given file was scanned by exinext itself; it wasn't being passed on
+ when Exim was called.
+
+PH/12 In the smtp transport, treat an explicit ECONNRESET error the same as
+ an end-of-file indication when reading a command response.
+
+
Exim version 4.60
-----------------
if it matched the actual IP address. This has been tidied up so that it
doesn't show the same IP address twice.
+PH/07 When both +timestamp and +memory debugging was on, the value given by
+ $tod_xxx expansions could be wrong, because the tod_stamp() function was
+ called by the debug printing, thereby overwriting the timestamp buffer.
+ Debugging no longer uses the tod_stamp() function when +timestamp is set.
+
+PH/08 When the original message was included in an autoreply transport, it
+ always said "this is a copy of the message, including all the headers",
+ even if body_only or headers_only was set. It now gives an appropriate
+ message.
+
+PH/09 Applied a patch from the Sieve maintainer which:
+
+ o fixes some comments
+ o adds the (disabled) notify extension core
+ o adds some debug output for the result of if/elsif tests
+ o points to the current vacation draft in the documentation
+ and documents the missing references header update
+
+ and most important:
+
+ o fixes a bug in processing the envelope test (when testing
+ multiple envelope elements, the last element determinted the
+ result)
+
+PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
+ Electronic Mail") by including:
+
+ Auto-submitted: auto-generated
+
+ in the messages that it generates (bounce messages and others, such as
+ warnings). In the case of bounce messages for non-SMTP mesages, there was
+ also a typo: it was using "Auto_submitted" (underscore instead of
+ hyphen). Since every message generated by Exim is necessarily in response
+ to another message, thes have all been changed to:
+
+ Auto-Submitted: auto-replied
+
+ in accordance with these statements in the RFC:
+
+ The auto-replied keyword:
+
+ - SHOULD be used on messages sent in direct response to another
+ message by an automatic process,
+
+ - MUST NOT be used on manually-generated messages,
+
+ - MAY be used on Delivery Status Notifications (DSNs) and Message
+ Disposition Notifications (MDNs),
+
+ - MUST NOT be used on messages generated by automatic or periodic
+ processes, except for messages which are automatic responses to
+ other messages.
+
+PH/11 Added "${if def:sender_address {(envelope-from <$sender_address>)\n\t}}"
+ to the default Received: header definition.
+
+PH/12 Added log selector acl_warn_skipped (default on).
+
+PH/13 After a successful wildlsearch lookup, discard the values of numeric
+ variables because (a) they are in the wrong storage pool and (b) even if
+ they were copied, it wouldn't work properly because of the caching.
+
+PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length
+ checking when decoding. Apparently there are clients that generate
+ overlong encoded strings. Why am I not surprised?
+
+PH/15 If the first argument of "${if match_address" was not empty, but did not
+ contain an "@" character, Exim crashed. Now it writes a panic log message
+ and treats the condition as false.
+
+PH/16 In autoreply, treat an empty string for "once" the same as unset.
+
+PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
+ extension "envelope-auth". The code is finished and in agreement with
+ other implementations, but there is no documentation so far and in fact,
+ nobody wrote the draft yet. This extension is currently #undef'ed, thus
+ not changing the active code.
+
+ Print executed "if" and "elsif" statements when debugging is used. This
+ helps a great deal to understand what a filter does.
+
+ Document more things not specified clearly in RFC3028. I had all this
+ sorted out, when out of a sudden new issues came to my mind. Oops."
+
+PH/18 Exim was not recognizing the "net-" search type prefix in match_ip lists
+ (Bugzilla #53).
+
+PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
+ canonical form (as documented). However, after a host name lookup from
+ the IP address, check_host() was doing a simple string comparison with
+ addresses acquired from the DNS when checking that the found name did
+ have the original IP as one of its addresses. Since any found IPv6
+ addresses are likely to be in abbreviated form, the comparison could
+ fail. Luckily, there already exists a function for doing the comparison
+ by converting both addresses to binary, so now that is used instead of
+ the text comparison.
+
+PH/20 There was another similar case to PH/19, when a complete host name was
+ given in a host list; looking up its IP address could give an abbreviated
+ form, whereas the current host's name might or might not be abbreviated.
+ The same fix has been applied.
