Version 2.11
------------

1. Adjustment of code for catching over-long multi-line SMTP responses to
do a better job in the case of packets not ending in \r\n.

2. Ignore any user-supplied whitespace (in particular, newlines) at the end of
smtp_banner; previously it was starting a continuation response, and then never
completing it, as there was nothing left.

3. Eximstats: computed incorrect total size of local deliveries.

4. If NO_SYSEXITS is set, don't make assumptions about the existence of exit
definitions in the strexits() function in os.c.

5. Tweak DGUX os.h file for strsignal and add HAVE_MMAP.

6. If a bounce message was constructed without any directing/routing having
occurred, Exim crashed. This could be provoked by -Mg, or if routing/directing
was deferred until the message retry time was exceeded. The bounce message
could be sent multiple times in the latter case, and did not contain a copy of
the original.

7. Don't insist on a transport for the domainlist router if verify_only is set.

8. The count of lines in messages read from stdin with the -i option (ended
only by EOF) was not getting set correctly.

9. When calling itself to send an error or a warning message, Exim wasn't
setting the -oi option, thus causing truncation of any enclosed text such as a
copy of the incoming message or the output of a pipe if it contained a line
with only a full stop in it.

10. Added dns_check_names_pattern to provide control over the syntax check.

11. If a DNS MX lookup fails the syntax check, don't go on to look for an A
record; and if called from lookuphost, don't go on to try widening the name.

12. Add the identity of the RBL domain to the log when in RBL warning mode,
and also to the messages output during -bh testing.

13. Do not stop scanning the list of RBL domains when one matches in warning
mode; ensure that X-RBL-Warning headers are added for all that match.

14. When testing with -bh, output a reminder after the final 250 after "." that
this is not for real.

15. Added max_username_length.

16. The log phrase "Error while handling error message" has been made more
accurate by changing it to "Error while reading a message with no usable sender
address", and a reference to the generating message added if there is one.

17. If -oee was set and the sender of a malformed incoming message was <>, so
that no error message could be sent, the return code was zero rather than 1
(i.e. it wasn't noticing it hadn't sent an error message).

18. If a non-SMTP message contains no recipients and error reporting is by mail
and no error message can be sent, the return code from Exim is now 2 instead of
1. This is so it can detect this case in the autoreply transport.

19. If the autoreply transport detects return code 2 for the message it has
submitted (no recipients) it no longer defers delivery. This means that
autoreplies to $sender_address when that is <> just get ignored (but there is
an entry on the log for the error).

20. Improved the error message that is given when an alias file or route list
file has the wrong mode, since this seems to confuse people.

21. Treat disconnection after end of data as a message error rather than a host
error.

22. Expanded the "file has wrong uid/gid" message to include the uids or gids
which don't match.

23. Installed PCRE 2.02 (minor tidies).

24. If a system filter discarded a message (by "seen finish" or similar) then
the log said "original recipients ignored", but had no => line. Now it contains
"=> discarded (message_filter)" instead, to be like the logging that happens
when a user filter discards a message.

25. Exinext was not displaying routing delays for specific addresses if the
domain successfully routed to a remote host. These can now exist in these
circumstances after temporary recipient-specific errors. Likewise it was not
capable of picking out message-specific retry data when given a message id.

26. Pipe delivery timeouts were not working if the writes to the pipe got
blocked (they only worked while waiting for the process to complete after doing
all the writing). Furthermore, after a timeout Exim just killed the process it
had created; if that process created further subprocesses they got left
running. It now makes the created process a process group leader, and kills the
whole process group, which will catch simple cases that don't themselves start
new process groups. Also, after detecting a timeout and killing the subprocess,
the third process that was reading from the output pipe didn't always die
immediately. The reading process is now forcibly killed along with the timed
out process group.

27. If a queryprogram process timed out, Exim wasn't killing it. It now kills
the whole process group, as for pipes (see 26 above).

28. If a pipe produced output, any error message was omitted from the bounce
message (this was to avoid "output message generated"), but this omitted
information about timeouts. The error information is now included except for
DEFER and OK returns.

29. Added "hosts_override" to the smtp transport.

30. Fixed two code infelicities in mailstore format delivery: (a) after opening
RDONLY, a stream of type "w+" was made (this fails on Linux), and the call to
fdopen() was not checked for errors; (b) the fd was closed directly, instead of
the stream.
