Hello,

If I have a network segment connected to a BGP peer, is there a way that I
can hang a box of some kind off of that segment that will sniff out and
block malicious/spam email before it hits the customers?

policy route your port 25 at an adjacent box.. use some sort of iptables rules 
to translate the ip address of the box and that will work also.
