RE: How do you stop outgoing spam?

Final comment on this subject (I promise) :)

How many (more) protocols are we willing to cripple in the name of
fighting spam?

Best regards,

Correct me if I'm wrong, but the web (ok, most of it) has been running
on TCP port 80 for quite a while now. So if you limit outgoing TCP
packets to port 80 (and probably some variations, such as HTTP+SSL) to a
few kbps, regardless of their destination, you don't hurt legitimate
users except some very rare cases such as HTTP uploads but you make life
less fun for spammers.
