Exim : SMTP connection from ... lost while reading message data
I've noticed lots of SMTP connection errors in my Exim main log (exim_mainlog)
I can't confirm this categorically, but I think all these failures are associated with incoming emails with (not particularly large) file attachments.
I'm running cPanel/WHM on a Fedora box, and the box is not under any cpu load (load averages consistently 0.3 or less)
Running this command:
grep 'lost while reading message' /var/log/exim_mainlog
... reveals a long list of error lines:

Does anyone have any ideas? Is this a problem at my end or with the sending (external) mail servers?
Running out of ideas here. Thanks in anticipation. :-)
