Exim changes in 4.34
1. Very minor rewording of debugging text in manualroute to say "list of
hosts" instead of "hostlist".
2. If verify=header_syntax was set, and a header line with an unqualified
address (no domain) and a large number of spaces between the end of the
name and the colon was received, the reception process suffered a buffer
overflow, and (when I tested it) crashed. This was caused by some obsolete
code that should have been removed. The fix is to remove it!
3. When running in the test harness, delay a bit after writing a bounce
message to get a bit more predictability in the log output.
4. Added a call to search_tidyup() just before forking a reception process. In
theory, someone could use a lookup in the expansion of smtp_accept_max_
per_host which, without the tidyup, could leave open a database connection.
5. Added the variables $recipient_data and $sender_data which get set from a
lookup success in an ACL "recipients" or "senders" condition, or a router
"senders" option, similar to $domain_data and $local_part_data.
6. Moved the writing of debug_print from before to after the "senders" test
for routers.
7. Change 4.31/66 (moving the time when the Received: is generated) caused
problems for message scanning, either using a data ACL, or using
local_scan() because the Received: header was not generated till after they
were called (in order to set the time as the time of reception completion).
I have revised the way this works. The header is now generated after the
body is received, but before the ACL or local_scan() are called. After they
are run, the timestamp in the header is updated.
Exim-exiscan version 4.34
22 - added SPF support via libspf_alt. Please read the
docs.
21 - Fix missing fclose() in regex.c. This was causing
scan directories not to be deleted on NFS spools.
- Remove "shutdown socket for writing" from clamd malware
code. It seems to cause problems with the latest
clamd 0.70 release.
- Fix allow tables in acl.c to disallow exiscan conditions
in the RCPT ACL.
- adapted patch to exim 4.34
