Cloud Pages + CNAME at apex & Email

I’m using Cloudflares Pages with a CNAME. It is at the APEX level hence the A and AAAA record are collapsed into a single CNAME record. Works fine.

Today I was granted access to Cloudflare Email. Quickly configured it. But incoming mail bounces with:

[email protected]: host linda.mx.cloudflare.net [172.65.14.34] said: 550 5.1.1 Domain does not exist (in reply to RCPT TO command)

It looks like internally Cloudflare is looking for the A or AAAAA record which obviously isn’t present.

How to solve this?

I don’t think this has anything to do with Pages or CNAMEs. There are many other posts on the 550 email routing error.
