Luckily I haven't encountered this with Comcast Cable (I use my own
mailserver [requires smtpauth] directly from home as Comcast seems to
have issues with mail and DNS on occasion).  If I ever do, I'll
immediately switch to one of the local DSL providers who support Linux.
Better for MTA's to block dynamic/home IP's using dnsbls than have the
ISP limit what you can do with your home computer.

You can also use port redirection to bypass this sort of thing.  Send on
port 10025 instead and direct your MTA to listen on both ports.
