Hi folks -- can someone illuminate me as to the "correct" way to setup reverse DNS records when one has multiple domains on a single IP, such as is (usually) the case with Plesk? The default in-addr.arpa file that Plesk creates contains a separate entry for each domain hosted, which in our case is several hundred, all in a single file. However, SOME mail servers end up rejecting messages from our customers because they fail a reverse DNS test. NuVox.com is an example. Their engineers say the long laundry list of multiple domains per single IP is causing the problem. Is there another, better way to set this up?
Many thanks!
Many thanks!
