Hi when we send mail we get a rdns_none
this only happens when the domain is proxied
i was wondering what the PTR record on cloud flare is for?
For proxied domains, Cloudflare responds to DNS queries with its own shared, dynamic IP addresses. Therefore, PTR records cannot be added to Cloudflare.
The PTR record option shown in the DNS Records dropdown is not for adding PTR records for Reverse DNS resolution. It is instead for adding a PTR Record to the Forward DNS resolution for the domain. PTR in Forward DNS is allowed under the DNS specification.
The main reason to have a PTR record is to prevent emails from ending up in spam folders. Since Cloudflare doesn’t support email traffic by default, you would instead need to set the PTR record where your email server is located. Please reach out to your email provider for assistance.
Can this help over come the rdns_none error that mail-tester gives?
