Why? Does your ISP allow you to run services on your cable setup?
My understanding is that most do not. It is easier to block dialup
addresses than to attempt to block on a case by case basis. Use your
ISP's smtp and be done with it.
Note also that many ISPs block port 25 explicitly forcing you to go
through their server, which has various anti-spam measures implemented.
(Other ISPs don't want competition for their spam generators. ATTBI
and Worldcom come to mind for that.)
