This software block SMTP sessions used by e-mail worms and
viruses on the NA(P)T router. It depends on netfilter
framework of Linux, or ipfw on FreeBSD.
It acts like proxy, intercepting outgoing SMTP connections
and scanning session data on-the-fly. When messages is
infected, the SMTP session is terminated. It's to be used
(mostly) by ISPs, so they can eliminate infected hosts from
their net work, and (preferably) educate their users.
