I am not sure where I have gone wrong in my configuration but I am getting the error Reverse DNS does not contain the hostname for my domain sparkdojo.com I had the hosting company set the PTR record to host2.sparkdojo.com and all of the tests I have conducted using dig and host seem to return the correct information. I have waited 24 hours because I read somewhere that the results might be cached or need to propagate but still I am still getting the error. I am hoping someone with more knowledge can determine what is wrong.

The error started showing up when I changed the hostname of the server and had the PTR record updated on the host IP. It was showing up as Hivelocity’s default PTR and hostname before so I wanted to make sure that it reflected my domain instead of theirs. There has not been any other changes other than what I listed above.
