Sending email to AOL with Outlook custom domain
I've setup a domain to work with Outlook custom domains and sending & receiving email is fine to everyone apart from AOL, contacted them and got this response:
"The reverse DNS (rDNS) for your IP is not a fully qualified, meaningful domain name. Please ask your ISP to change your rDNS (PTR record) to a fully qualified, meaningful domain name, and make sure your domain name is reflected in the rDNS."
I added the MX and TXT records at setup however I'm a little unsure of what else I need to do, been searching their docs to no avail.
Anyone have any suggestions? Much appreciated.
