COMCAST SUCKS: NameZero EMAIL BEING BLOCKED

From the NameZero Support Area:
The following ISPs are currently blocking e-mail from our servers: Comcast, AOL and BellSouth. We are currently working on resolving these issues with them and hope to have the blocks lifted soon. In the mean time, you can help the situation by submitting a support request directly with your ISP, letting them know that you are being affected by their decision to block our servers.

I am not happy.
