>Description:
The spamass-milter port will hang if the mailserver receives multiple e-mails at the same time. Until the milter is restarted, all mail will be delayed (waiting for the milter to time out) and then delivered unfiltered. Following is a log excerpt showing a message that was processed correctly followed by five messages sent at once from another machine ("buff"), which caused the milter to hang:

>How-To-Repeat:
Set up spamd (from SpamAssassin) and spamass-milter as instructed in the ports. From another machine, run a script like this:
#!/bin/sh
for i in `jot 5 1`; do
echo "test $i" | mail -s "test $i" user@test.mail.server
done
>Fix:
If the spamass-milter software is built from the latest CVS sources with patch 349 applied, the problem goes away. A reasonable fix would be one of: 1) waiting for the next official release of the software (if it's soon), 2) modifying the existing port to use the latest sources and apply the patch, or 3) fork the port (e.g. spamass-milter-devel) and have the "unstable" fork use the newest sources and relevant patches.
