I just ran a test on mail-tester.com and it mentioned "We didn't find a server (A Record) behind your hostname host.***.com.".
But my hostname clearly has an A Record that includes its IP address. Any attempt to add an A Record in WHM through "Add an A Entry for Your Hostname" confirms that "a DNS entry for host.***.com already exists."
Has anyone run into this problem before?
*(I also noticed that my reverse DNS is not matching. The hostname host.***.com is only showing for sent mail, whereas the rDNS shows the IP is associated with a domain that looks like it belongs to the hosting provider that provided us with the IP. Not sure if this would have any bearing on the hostname's A Record not being recognized.)*
Thanks!
