Actually spammers almost always have near perfect DNS, they know it must be right for it to work. What YOUR reading is the bogus headers that have nothing at all to do with DNS, but are simply inserted to fool people who think header records are somehow validated. Again, this is a foolish attempt that is probably denying far more valid email than any spam it is preventing. And again, it is not me that is inconvienince, but the person who is not receiving valid email that is suffering. -- Rod Grimes [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
