For some weird reason we can not add a certain CNAME record without producing an error from Cloudflare: An A, AAAA or CNAME record already exists with that host. (Code: 81053)
The record is a CNAME for an SMTP server.
When I search for SMTP through DNS, I get No DNS records found.
My guess is there is an issue with Cloudflare’s DNS since this record does not exist.
The only other DNS record that comes close is another CNAME record that has API, but it shouldn’t have any effect on SMTP.
Any help is greatly appreciated.
