I found that Comcast only blocks "Residential" subscribers from port 25.
The minute I upgraded to a "Commercial" account, all restrictions were removed.
The best part was that for a commercial account with one dedicated IP
address, it was cheaper than the residential service was.
Not sure this approach will work for all though.

Most ISP's block port 25 outgoing, the problem I am seeing.
