My server just was listed with Spamcop. Before I exercise my -one time- option to de-list it I need to verify that indeed my server is not sending spam. I have 3 win boxes routing through my FreeBSD box. Also there are a few windows computers in the outside world that send mail through my server via port 26 using their login and password. I know it is possible for viruses to install a stand-alone smtp server on win boxes. That is one suspicion I have. My question; What tool would I use to see if unauthorized mail is being sent via my server? Note that I am running tmda, so that I have around 80 emails per minute being sent out; to request verification on my standard incoming mail, (therefore it is too complicated to just watch -all- mail being sent out, and try and decode legitimate from illegitimate).
