That probably depends a lot on the topology in question... Doing it on
'ethernet' is far different from doing it on T1 over ATM or
channelized oc-48... A Checkpoint FW can do this sort of thing with a
'security server' (though performance is certainly a question...).

I think you're also always stuck in a store-and-forward mode so 'on
the wire' isn't really helpful for SMTP, often you can't make a
decision about an email without getting a large portion of it down, so
snuffing connections mid-stream isn't going to help your email infra
very much :(
