I'm on a dedicated box and some of my server's mail was being marked as spam and blacklisted. I checked one of the blacklisters and they said it was because of a generic PTR. So here's what I did 1) Created a DNS Zone for the IP I wanted (in this example let's say 192.168.0.1) and the domain I put 0.168.192.in-addr.arpa (as per the WHM documenation) After I do that the documentation says I need to edit the zone. Question is do I edit the newly created zone above, or am I editing the domain I want to apply the PTR to? I edited the newly created zone and created a PTR record of 1 14400 in PTR example.com Is that what I'm supposed to do? Reason I ask is because I did a Code: host 192.168.0.1 and it's not showing the pointer as example.com.
