I contacted COMCAST the information they provided was pretty much useless. They subscribe to Spamhaus who will unblock the IP address but then block it again within a few days. A quick check of http://whatismyipaddress.com/staticpages/index.php/is-my-ip-address-blacklisted will show that more than a few anti-spam sites are blocking BTL.

The thing that really p.o's me is that everyone is saying business is down in Belize and I have to wonder if this isn't one of the reasons.
