I now see the cause of your confusion. "Make sure your PTR and A records match", in this context, means, exactly as the RFC states, that "For every IP address, there should be a matching PTR record in the in-addr.arpa domain." And "That all IP addresses have a corresponding PTR record." It does NOT say "The PTR of an IP address should match that of an A record with the same name." In the context of this RFC, "match" is more like a matching pair: for every A record there should be a PTR defined also. In the OP's post, he wanted to 'penalize' a relay because it's HELO name was not identical to the PTR. And that's just plain silly, and not supported by any RFC I know. - Mark
