I have been asked to provide a machine that can scan all outbound smtp
traffic on the network. We have loads of students and some use own mail
clients, they ahve own unprotected laptops etc etc - so we will make a
firewall rule that all outbound on port 25 goes to this new mail relay.

I am already familiar with mailscanner and postfix.

Is this simply a matter of building a mailscanner machine, config
postfix to access mail from the firewall interface only, and bob's your
mothers brother?

Who does aoutbound scanning - how do you do it? anyone got any better
suggestions for wyhole of company outbound scanning?
