Change log file for Exim from version 4.21
-------------------------------------------
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
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.
+ 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<time>, the effect of -R or -S was ignored,
+ and queue runs started by the daemon processed all messages. This has
+ been fixed so that -R and -S can now usefully be given with -q<time>.
+
+PH/40 Import PCRE release 6.7 (fixes some bugs).
+
+PH/41 Add bitwise logical operations to eval (courtesy Brad Jorsch).
+
+PH/42 Give an error if -q is specified more than once.
+
+PH/43 Renamed the variables $interface_address and $interface_port as
+ $received_ip_address and $received_port, to make it clear that these
+ values apply to message reception, and not to the outgoing interface when
+ a message is delivered. (The old names remain recognized, of course.)
+
+PH/44 There was no timeout on the connect() call when using a Unix domain
+ socket in the ${readsocket expansion. There now is.
+
+PH/45 Applied a modified version of Brad Jorsch's patch to allow "message" to
+ be meaningful with "accept".
+
+SC/01 Eximstats V1.43
+ Bug fix for V1.42 with -h0 specified. Spotted by Chris Lear.
+
+SC/02 Eximstats V1.44
+ Use a glob alias rather than an array ref in the generated
+ parser. This improves both readability and performance.
+
+SC/03 Eximstats V1.45 (Marco Gaiarin / Steve Campbell)
+ Collect SpamAssassin and rejection statistics.
+ Don't display local sender or destination tables unless
+ there is data to show.
+ Added average volumes into the top table text output.
+
+SC/04 Eximstats V1.46
+ Collect data on the number of addresses (recipients)
+ as well as the number of messages.
+
+SC/05 Eximstats V1.47
+ Added 'Message too big' to the list of mail rejection
+ reasons (thanks to Marco Gaiarin).
+
+SC/06 Eximstats V1.48
+ Mainlog lines which have GMT offsets and are too short to
+ have a flag are now skipped.
+
+SC/07 Eximstats V1.49 (Alain Williams)
+ Added the -emptyok flag.
+
+SC/08 Eximstats V1.50
+ Fixes for obtaining the IP address from reject messages.
+
+JJ/03 exipick.20061117.2, made header handling as similar to exim as possible
+ (added [br]h_ prefixes, implemented RFC2047 decoding. Fixed
+ whitesspace changes from 4.64-PH/27
+
+JJ/04 exipick.20061117.2, fixed format and added $message_headers_raw to
+ match 4.64-PH/13
+
+JJ/05 exipick.20061117.2, bug fixes (error out sooner when invalid criteria
+ are found, allow negative numbers in numeric criteria)
+
+JJ/06 exipick.20061117.2, added new $message_body_missing variable
+
+JJ/07 exipick.20061117.2, added $received_ip_address and $received_port
+ to match changes made in 4.64-PH/43
+
+PH/46 Applied Jori Hamalainen's patch to add features to exiqsumm.
+
+PH/47 Put in an explicit test for a DNS lookup of an address record where the
+ "domain" is actually an IP address, and force a failure. This locks out
+ those revolvers/nameservers that support "A-for-A" lookups, in
+ contravention of the specifications.
+
+PH/48 When a host name was looked up from an IP address, and the subsequent
+ forward lookup of the name timed out, the host name was left in
+ $sender_host_name, contrary to the specification.
+
+PH/49 Although default lookup types such as lsearch* or cdb*@ have always been
+ restricted to single-key lookups, Exim was not diagnosing an error if
+ * or *@ was used with a query-style lookup.
+
