No, he didn't. I proposed "XM" records, to denote mail sources (as opposed to MX records, which denote mail sinks) back in 2003. See message 20030321212627.ga22...@gsp.org in news.admin.net-abuse.email, 3/21/2003 as well as 20030527182810.ga20...@gsp.org on spam-l, 5/27/2003, among others. Of course, those who patent software invariably lie about their claims and pretend prior art doesn't exist, so this isn't really surprising. ---rsk _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
