I'm not defending Comcast; personally, my reaction to their blocking 
would be to switch to a different provider. 

If I understand correctly, you have a colocated mail server that is unrelated 
to Comcast, and some or all of your customers use Comcast as their ISP. 
Comcast is making life difficult for them. 

If this is what we're talking about, then there's not a lot you can do. 
Their options are essentially (1) convince Comcast to stop blocking 
their access; (2) implement a workaround; or (3) switch to a different 
ISP. It's not a problem that you can fix for them; the best you can do 
is to give them advice on how you think they should proceed.
