OS: FreeBSD 5-3-RELEASE

We have a front-end server facing the public side of our network and noticed
in the logs we are getting tons of messages and the end result is Deferred:
Operation timed out. Now looking closely at the several of these messages,
they are showing up trying to send several times a day. Here's an example of
the random messages we are seeing and the frequentcy. Looks like virus
related, but can't pin it down where these are coming from? Hints? Tips?
