Really?!  The appropriate way to send mail from a dynamic IP like the 
one Comcast gives you is to relay through their smart host.  That only 
works if the blacklists block the sending MTA, not any IP in the 
received headers.

Can you say more (perhaps provide a bounce) that shows that behavior?  I 
would think that it's a bad practice and it would be interesting to know 
who is doing it and why.
