+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?
