How do I add a PTR record to Cloudflare?

Since Cloudflare uses shared and dynamic IP addresses to resolve to your domains, we are not able to add PTR records for any Cloudflare IPs. The main reason to have rDNS or PTR records is to prevent emails from ending up in spam folders. Since Cloudflare doesn't support email traffic, you would need to set the rDNS or PTR record where your email server is located.
