I’ve read Cloudflare’s entry on PTR records, but I’m not clear on certain details regarding how to manage DNS once a PTR record has been set up.
We host a website (with Cloudflare service) for a client – another company hosts their email. The client wants to set up a PTR record to prevent their group emails from ending up in spam folders. I need to guide the company hosting email on the PTR issue.
Should I have them set up a PTR record where the email is hosted?
I’m quite confused about the DNS side of this. I’m seeing guidance that advises turning off the DNS/HTTP proxy for the mail subdomain – but there’s no option for doing so (no orange cloud icon) beside MX record entries.
Do I need to set up a new subdomain for email service? And would this be an MX record, or some other kind of record?
