I'm also adding my Grand Central and Vonage numbers to the registry.

This would be a great list to add to our blacklist of web sites. But I don't see how to download the whole (213,000) thing at once.

Comcast is blocking some mail - not sure if it's on our end (Blue Dot) or on the receivers side (sloan.mit.edu is the domain reported...).

Anyway, this form will allow you to report a problem with the spam blockers at Comcast.
