As I wrote in my other reply in this thread I think this is the bug reported at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=527862 . Message #47 in that thread mentions a patch that can be downloaded from http://j-chkmail.ensmp.fr/libmilter . The "debian-lenny/" directory at that site contains patched libmilter debian packages for "Lenny". I didn't test/use those packages as I'm running Debian Squeeze. A quick and dirty workaround is inspecting the mail-logs and restarting mimedefang in case of errors. Something like: tail -n100 /var/log/mail.log | \ grep -q 'Milter (mimedefang): to error state' && \ /etc/init.d/mimedefang restart frequently run by cron should do the job (not jet tested). The regular expression in the grep command is based on my logs after the last crash a few weeks ago.
