You're lucky, Comcast shutdown access to port 25 inbound and outbound
to me. Here's my rant about it:

I switched over to using Gmail for my outbound service:

I've also had a great many problems with Comcast, mail list
and any html email. The mail list were getting bounced (often)
and the outbound html email was getting dropped. I've since moved
as much of my email off Comcast as possible. And before anyone
get too crazy I usually send out no more than 10 emails a day.
I receive a lot more as I'm on about 15 mail lists.
