Received_SPF: record within spam in SpamCop Lounge Posted September 12, 2005 No, that line was not put there by Postini. That is what I figured. 32628[/snapback] The spam was sent from a machine at IP 184.108.40.206, part of the CNC Group-Henan province network. It forges headers to look like it came through gmail forwarding mail from a go.com account ( go.com is owned by Disney and has a bad history of being abused by spammers). The Received_SPF is just another forged header - go.com does not use SPF. Most likely the domain her0es.net (the spamvertised domain) is operated by Leo Kuvayev (currently #2 at Spamhaus). - it uses a set of registration records he has used on dozens of other domains It is mortgage spam, so if he is following pattern, there exists a nearly identical domain named her0es.com, which was likely registered within seconds of this one, but not yet used.
