Many other cable providers have managed to block port 25/tcp

If they block Port 25, the spammers will simply use another port.

There are many legitimate email users who send outbound email via Port 25 using their own hosted email services.

Correct me if I'm wrong, but I thought basic Comcast internet service (along with most other DHCP internet services) prohibits server functions on their basic residential internet package.

Huh? My mailserver only listens for traffic on port 25/tcp, so if spammer try to use another port, they're not going to get anywhere.

You're right, but most of us who do these things are not running servers on Comcast connections. Rather, what we are doing is buying our own domain and hosting, and sending email through that host, using that host's port 25. If Comcast were to block outgoing port 25, then email would not work.

Although most hosting companies do provide an alternative port to send email, it is still not fair that users who keep their machines virus-free should have our connections hobbled because some idiot is too lazy to maintain their system.
