I got another question: Is the port 80 blocked?
No but some are, read here: »Ameritech - SBC FAQ »Does ameritech block any ports? (Update 08/16/2005)

Well, since a lot of people out there do not have routers or firewalls, I'm for blocking some ports that are known for having vulnerabilities or just resource sharing like Windows NetBios port 139.

Blocking port 25 outbound traffic that is not destined for a SBCYahoo mail server also makes a lot of sense. I'm for anything that helps to stop the spammers.

I still remember when spammers hijacked my SMTP server about 5 years ago. It was my fault anyway. I didn't set up the SMTP service correctly and left the mail relay enabled.
