My bad. I ran into problems sending e-mail, checked their site for the
settings & saw this FAQ so I quit trying. I'm not sure what I had wrong but
I'll try again later to see if I can get it working. The router between the
cable modem & my server may not have 135 & 445 open. Which others should I
open up?
It was MSBlast & their FAQ said it was temporary. Here's the quote...
"Why can't I get my Microsoft Exchange E-mail?
To help protect our customers from the effects of the recent MSBlast
worm, Comcast has temporarily shut down access to ports 135 and 445. These
are the ports that the MSBlast worm uses to propagate itself - in addition
to being the ports that Microsoft Exchange servers use by default. Comcast
continues to take precautionary steps to stem the affects of this worm on
our network and protect our customers. We will continue to monitor the
situation as it evolves. This does not affect your @Comcast.net E-mail."
