Yesterday I set up a test MIAB install to try things out before migrating an existing mail server over. Everything went swimmingly and I was able to successfully set up rDNS on my virtual server with no issues. I reinstalled a fresh Ubuntu 14.04 to do the actual migration. I followed the guide and again everything went smoothly. Status Check is all green check marks except:
When I try to change the rDNS in my VPS control panel I get the error:
Cannot find ‘A’ DNS record type for the specified reverse.
Using MXToolbox I do a search for A records for mail.currentsite.com and everything looks fine so far as I can tell. Any ideas? Is it just an issue with propagation? I did finished this initial setup approx 12 hours ago.
Side note: I also tried creating an A record from the Custom DNS page adding just “mail” for the subdomain and the correct IP Address. When I click “Set Record” the record is created but the pop up box says “something isn’t right”. I’ve since deleted that record just in case it was throwing a wrench in things.
