You should have a close look at what was going on in the panic, reject
and main Exim logs around that time.  Off the top of my head, I can't
think of any config option that will allow Exim to abort sessions
unexpectedly like this.

Hopefully not -- that option will cause Exim to give 452 responses for
all recipients over the limit -- it won't cause Exim to disconnect.

Mailman dequeues messages that seem to generate serious problems for
the receiving MTA (which an unexpected disconnection certainly is an
indication of).  If Mailman dequeued the message due to getting 452
responses, that would be _very_ bad.
