Static IP I assume?  Someone told me that the Comcast static IPs are in 
the same ranges as the DHCP addresses, so you'll get RBL'd if you try to 
run a mail server.  I'll be interested to hear if that's still the case, 
and how it goes in general trying to get a correct PTR record.  As I've 
commented on this list before, I personally don't think Comcast has any 
idea how to run a large DNS infrastructure.

Please do let us know how it all goes now, and in a few weeks...

Thanks,
JP

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
