I need a PTR record for my mail server. Do I add it to my domain's DNS?
Usually, you do not add it to your domain's regular DNS zone. A PTR record provides a reverse lookup, mapping an IP address to a hostname. It is managed by the provider that controls the IP address, or by an administrator responsible for a delegated reverse DNS zone.
If you manage a mail server, check with your server or IP address provider about configuring reverse DNS. The hostname specified in the PTR record should itself have an A or AAAA record pointing back to that IP address. A correctly configured PTR record can matter during checks by receiving mail servers, but it does not guarantee inbox delivery.
