Yeah, that is common, but that's not what is happening here. The name and address do not match. You would expect it is possible multiple names to map to one IP address, but here we have a machine giving a name which corresponds to a _different_ IP than the one from which the connection is coming. It looks like it is lying about being Mail6.sc.rr.com. But I am not sure if that is even the problem or not. -- Crist J.
