There are many other services available with a much better reputation, and

JFTR, it's controlledmail.com.
Does anyone have current info on Comcast.net?
Comcast is one of the worst for confusing everyone trying to pin down their
server addresses. I use their entire IP blocks:
24.147.0.0/16 65536
63.240.76.0/23 512
204.127.0.0/16 65536
216.148.227.0-255 256
Totals: 4 131840
You might consider building a regexp out of the server names Rene Barbier
provided.
My requirements may be somewhat different than yours, however. I use this
list for *whitelisting* not *blacklisting*. If the IP is within one of
these ranges, we assume it really is comcast.net, and tag it with a 'B'
rating. Recipients who will accept B-rated mail can then receive mail from
comcast.net with no false rejects.

Not likely. They have no real incentive to do so, and the mere mention of
the word 'spam' will shut down any communication with them. This will
change only when they start hearing from their own customers, like
yourself, that their reputation is hurting their business. This may happen
when reputation systems like the one I am working on at open-mail.org,
become more widely used.
Back when I used Comcast's MTAs, I asked and was unable to find someone I
could talk to that could understand what I was asking for.
