There's a LOT of confusion here, and mis-information spreading. To summarize: 1. REQUIRED: A reverse DNS entry 2. IMPORTANT: The host name of the reverse DNS entry has an A record that points back to the same IP 3. NOT IMPORTANT: The actual host name in the reverse DNS entry In this case, he has #1 and #2, but not #3. That's fine. For example, if your mailserver is named mail.example.com at IP address 192.168.1.1, then [1] 192.168.1.1 needs to have a reverse DNS entry (which could be mail.example.com, some_other_host.example.com, or host.other_domain.com), [2] Assuming that the reverse DNS entry for 192.168.1.1 points to host.other_domain.com, then host.other_domain.com should have an A record pointing back to 192.168.1.1, [3] host.other_domain.com does NOT have to match mail.example.com. Actually, I am not confused here nor am I spredding mis-information. Your examples put the issue to the masses more 'clearly'.
