Hello

I dunno if the reason is the same, but I've had some odd behaviour with
clamav and certain emails with attach.

Clamav will freeze up while scanning certain message (not too big, since I
don't scan mails over 2MB) and exim becomes so slow after that (clamav hogs
the CPU) that connections take forever (in some cases causing smtp
timeouts).

I have clamav set to not descend more than 1 level into zip files. rars are
not scanned.

This only happens on Solaris and FreeBSD, not on Linux, for some reason.
This is also not very easy to reproduce, since most attach (no matter what
size) go thru without problem.

Usually the solution is to kill the clamava process and restart it. I'm
using the standard exiscan mechanism to communicate with clamav and
spamassassin. Maybe I'll give sophie a try.
