Duane,

Comcast has apparently installed a more aggressive anti-spam routine
which is falsely rejecting some e-mails.  

Obviously, I received this Ham-Computers qth.net mailing, but that was
from qth.net, not your ISP or your account at your ISP. 

During the last month or so, Drakelist sourced e-mail was rejected by
Comcast for several days.  I believe that issue was resolved by Thom,
the Drakelist moderator.  Contact him for details.

I would suggest setting up a simple, controlled test e-mail from you,
using your ISP, to a Comcast e-mail account.  Simple, like a subject of
"Test" and a body of "This is a test.".  If you have one of the free
e-mail accounts, sending the same message from it might prove to be
useful. 

Good luck, 
Joe, K9HDE
