How do I configure rDNS if I'm using CloudFlare and CNAME is setup as mail
Hello,
Need some help. Using Cloudflare and trying to add A or AAAA record but issue is that the CNAME is already their and every time I try to add that A or AAAA record it will output an error that is shown below.
A CNAME record with that host already exists. For more details, refer to https://developers.cloudflare.com/dns/manage-dns-records/troubleshooting/records-with-same-name/. (Code: 81054)
Appreciate some help? Thanks.

Hi @mmo-1 - It's not possible to set up rDNS while using a reverse proxy service, as the domain needs to have a visible A record that points to the IP address you want to set up rDNS for.
However, after you set up rDNS you can change the DNS back as needed.
If there’s anything else I can do for you or any questions I can answer please don’t hesitate to ask.
