Change log file for Exim from version 4.21
-------------------------------------------
Exim version 4.60
-----------------
-PH/01 In the default runtime configuration, move the checks for
- relay_from_hosts and authenticated clients from after to before the
- (commented out) DNS black list checks.
+PH/01 Two changes to the default runtime configuration:
+
+ (1) Move the checks for relay_from_hosts and authenticated clients from
+ after to before the (commented out) DNS black list checks.
+
+ (2) Add control=submission to the relay_from_hosts and authenticated
+ clients checks, on the grounds that messages accepted by these
+ statements are most likely to be submissions.
+
+PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
+
+ (1) Generate an error if the third argument for the ${prvs expansion is
+ not a single digit.
+
+ (2) Treat a missing third argument of ${prvscheck as if it were an empty
+ string.
+
+ (3) Reset the variables that are obtained from the first argument of
+ ${prvscheck and used in the second argument before leaving the code,
+ because their memory is reclaimed, so using them afterwards may do
+ silly things.
+
+ (4) Tidy up the code for expanding the arguments of ${prvscheck one by
+ one (it's much easier than Tom thought :-).
+
+ (5) Because of (4), we can now allow for the use of $prvscheck_result
+ inside the third argument.
+
+PH/03 For some reason, the default setting of PATH when running a command from
+ a pipe transport was just "/usr/bin". I have changed it to
+ "/bin:/usr/bin".
+
+PH/04 SUPPORT_TRANSLATE_IP_ADDRESS and MOVE_FROZEN_MESSAGES did not cause
+ anything to be listed in the output from -bV.
+
+PH/05 When a filter generated an autoreply, the entire To: header line was
+ quoted in the delivery log line, like this:
+
+ => >A.N.Other <ano@some.domain> <original@ddress> ...
+
+ This has been changed so that it extracts the operative address. There
+ may be more than one such address. If so, they are comma-separated, like
+ this:
+
+ => >ano@some.domain,ona@other.domain <original@ddress> ...
+
+PH/06 When a client host used a correct literal IP address in a HELO or EHLO
+ command, (for example, EHLO [1.2.3.4]) and the client's IP address was
+ not being looked up in the rDNS to get a host name, Exim was showing the
+ IP address twice in Received: lines, even though the IP addresses were
+ identical. For example:
+
+ Received: from [1.2.3.4] (helo=[1.2.3.4])
+
+ However, if the real host name was known, it was omitting the HELO data
+ 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.
Exim version 4.54
PH/05 Some modifications to the interface to the fake nameserver for the new
testing suite.
+PH/06 Add ${if def:sender_address {(envelope-from <$sender_address>)\n\t}}
+ into the default Received: header string.
+
+
Exim version 4.53
