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
local IP, and the "valid-client-cert option" if a client certificate has
been verified.
+PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
+ authenticators. This can be used for authorization after authentication
+ succeeds. (In the case of plaintext, it servers for both authentication
+ and authorization.)
+
+PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
+ if any retry times were supplied.
+
+PH/24 Exim crashed if verify=helo was activated during an incoming -bs
+ connection, where there is no client IP address to check. In this
+ situation, the verify now always succeeds.
+
+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<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.
+
