I’m trying to set up reverse DNS on a server. On most other servers I have worked with the PTR is set by the provider of the server. In this case however since I am using cloudflare to do DNS for the primary domain name of the server they are telling me that I have to set up a PTR record in cloudflare.
The main reason I am working on this is that email being sent out from the server is getting knocked for spam because the PTR record that you can see if you do a PTR lookup on the server’s hostname is something like:
I tried adding a PTR record that in cloudflare looks like this:
PTR 220.127.116.119 server27.host.name Auto DNS Only
However I am fairly sure that that isn’t working. I know the IP address and the server’s hostname are correct. Am I just putting them in incorrectly? Or do I need something else in there?
