Bah! This guy is not too bright.

Namely, even if spammers were to move to other avenues, it's still worth closing port 25 to stop them from using it.

Sooo.... spammers can find a way around it but it is worth blocking it anyway.... sure, if that is worth it then why not block all ports and shut everything down? ISP's blocking 25 is a stupid solution. Microsoft actually making harder to hijack your computer is the solution.

I think so too--if you are running a mail server, that mail server can use any port it wants to. There's nothing magical about port 25.
