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. + + Exim version 4.60 ----------------- @@ -64,6 +122,108 @@ PH/06 When a client host used a correct literal IP address in a HELO or EHLO 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.

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. + Exim version 4.54 ----------------- @@ -93,6 +253,7 @@ PH/05 Some modifications to the interface to the fake nameserver for the new testing suite. + Exim version 4.53 -----------------
