Thanks to + Jan Srzednicki. + +PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not + issue a MAIL command. + +PH/02 In an ACL statement such as + + deny dnslists = X!=127.0.0.2 : X=127.0.0.2 + + if a client was not listed at all, or was listed with a value other than + 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list, + the condition was not true (as it should be), so access was not denied. + The bug was that the ! inversion was incorrectly passed on to the second + item. This has been fixed. + +PH/03 Added additional dnslists conditions == and =& which are different from + = and & when the dns lookup returns more than one IP address. + +PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the + cipher suites used by GnuTLS. These options are ignored by OpenSSL. + +SC/01 Updated eximstats to collate all SpamAssassin rejects into one bucket. + + +Exim version 4.66 +----------------- + +PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one + fixed by 4.65/MH/01 (is this a record?) are fixed: + + (i) An empty string was always treated as zero by the numeric comparison + operators. This behaviour has been restored. + + (ii) It is documented that the numeric comparison operators always treat + their arguments as decimal numbers. This was broken in that numbers + starting with 0 were being interpreted as octal. + + While fixing these problems I realized that there was another issue that + hadn't been noticed. Values of message_size_limit (both the global option + and the transport option) were treated as octal if they started with 0. + The documentation was vague. These values are now always treated as + decimal, and I will make that clear in the documentation. + + +Exim version 4.65 +----------------- + +TK/01 Disable default definition of HAVE_LINUX_SENDFILE. Clashes with + Linux large file support (_FILE_OFFSET_BITS=64) on older glibc + versions. (#438) + +MH/01 Don't check that the operands of numeric comparison operators are + integers when their expansion is in "skipping" mode (fixes bug + introduced by 4.64-PH/07). + +PH/01 If a system filter or a router generates more than SHRT_MAX (32767) + child addresses, Exim now panics and dies. Previously, because the count + is held in a short int, deliveries were likely to be lost. As such a + large number of recipients for a single message is ridiculous + (performance will be very, very poor), I have chosen to impose a limit + rather than extend the field. + + Exim version 4.64 ----------------- +TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a + leftover -K file (the existence of which was triggered by #402). + While we were at it, introduced process PID as part of the -K + filename. This should rule out race conditions when creating + these files. + +TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing + processing considerably. Previous code took too long for large mails, + triggering a timeout which in turn triggers #401. + +TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used + in the DK code in transports.c. sendfile() is not really portable, + hence the _LINUX specificness. + TF/01 In the add_headers option to the mail command in an Exim filter, there was a bug that Exim would claim a syntax error in any header after the first one which had an odd number of characters @@ -166,6 +248,185 @@ PH/25 Applied John Jetmore's -Mset patch. PH/26 Added -bem to be like -Mset, but loading a message from a file. +PH/27 In a string expansion for a processed (not raw) header when multiple + headers of the same name were present, leading whitespace was being + removed from all of them, but trailing whitespace was being removed only + from the last one. Now trailing whitespace is removed from each header + before concatenation. Completely empty headers in a concatenation (as + before) are ignored. + +PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John + Jetmore). It would have mis-read ACL variables from pre-4.61 spool files. + +PH/29 [Removed. This was a change that I later backed out, and forgot to + correct the ChangeLog entry (that I had efficiently created) before + committing the later change.] + +PH/30 Exim was sometimes attempting to deliver messages that had suffered + address errors (4xx response to RCPT) over the same connection as other + messages routed to the same hosts. Such deliveries are always "forced", + so retry times are not inspected. This resulted in far too many retries + for the affected addresses. The effect occurred only when there were more + hosts than the hosts_max_try setting in the smtp transport when it had + the 4xx errors. Those hosts that it had tried were not added to the list + of hosts for which the message was waiting, so if all were tried, there + was no problem. Two fixes have been applied: + + (i) If there are any address or message errors in an SMTP delivery, none + of the hosts (tried or untried) are now added to the list of hosts + for which the message is waiting, so the message should not be a + candidate for sending over the same connection that was used for a + successful delivery of some other message. This seems entirely + reasonable: after all the message is NOT "waiting for some host". + This is so "obvious" that I'm not sure why it wasn't done + previously. Hope I haven't missed anything, but it can't do any + harm, as the worst effect is to miss an optimization. + + (ii) If, despite (i), such a delivery is accidentally attempted, the + routing retry time is respected, so at least it doesn't keep + hammering the server. + +PH/31 Installed Andrew Findlay's patch to close the writing end of the socket + in ${readsocket because some servers need this prod. + +PH/32 Added some extra debug output when updating a wait-xxx database. + +PH/33 The hint "could be header name not terminated by colon", which has been + given for certain expansion errors for a long time, was not being given + for the ${if def:h_colon_omitted{... case. + +PH/34 The spec says: "With one important exception, whenever a domain list is + being scanned, $domain contains the subject domain." There was at least + one case where this was not true. + +PH/35 The error "getsockname() failed: connection reset by peer" was being + written to the panic log as well as the main log, but it isn't really + panic-worthy as it just means the connection died rather early on. I have + removed the panic log writing for the ECONNRESET error when getsockname() + fails. + +PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue + runs only) independently of the message's sender address. This meant + that, if the 4xx error was in fact related to the sender, a different + message to the same recipient with a different sender could confuse + things. In particualar, this can happen when sending to a greylisting + server, but other circumstances could also provoke similar problems. + I have changed the default so that the retry time for these errors is now + based a combination of the sender and recipient addresses. This change + can be overridden by setting address_retry_include_sender=false in the + smtp transport. + +PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the + remote server are returned as part of bounce messages. This was not + happening for LMTP over a pipe (the lmtp transport), but now it is the + same for both kinds of LMTP. + +PH/38 Despite being documented as not happening, Exim was rewriting addresses + in header lines that were in fact CNAMEs. This is no longer the case. + +PH/39 If -R or -S was given with -q
