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?

Do you mean a host that can have all tcp/25 routed to it, transparently
pick-up/scan/re-deliver emails for your customers? or did you mean
something you could add to your customer relay boxes? (or your MX hosts
that customers use) Or thirdly, something to protect the internet from
your users?
