This has only started happening in the last week or so, and I've drawn a
blank as to the cause.
We have exim V4.3 installed along with ClamAV and SpamAssassin and its
perfectly happy to receive emails. However if someone tries to send a
reasonably sized email (an attachment) then we get a timeout error in
Outlook. This also happens with our Linux and Mac users. Small emails seem
unaffected and get sent fine.
Nothing appears in the log files (in fact it looks like the mail hasn't got
to the server to get sent).
This is obviously causing major problems, and its got to the stage now,
where I'm considering rebuilding the mail server.
I've even cleared down the mail queue in case that was the problem.
If anyone has any ideas why this might be happening, let me know. The only
thing we've noticed is all of a sudden SpamAssassin is using a lot of memory
and the server is running out, but we've restricted SA to only scan messages
up to 256K.
