This will never return a CNAME as the CNAME will be flattened and can only return A/AAAA records, either due to using the proxy or, if “DNS only”, because a CNAME at the apex is not permitted.

Can you show a screenshot of your DNS records for the TXT record, I can’t see any for the apex domain…

Hello! You can find all CNAME and TXT records on the screenshot. I’m wondering how it is possible :slight_smile: :sweat_smile:

There’s no TXT record for the apex domain, only _dmarc, and that resolves ok as do all the others…

dig +short em9451.netwall.host txt
u50463910.wl161.sendgrid.net.
"v=spf1 include:sendgrid.net ~all"

You don’t have any MX records though which you’ll need to receive email.

Thank you for your reply!

The issue is not related to mail configuration or missing MX records

The problem is that some DNS records (TXT and CNAME) are not visible in public DNS at all, even though they are present in my Cloudflare dashboard and set as DNS Only

This appears to be a Cloudflare DNS bug for my domain

Thank you!

For example, some CNAME and TXT records are present in the dashboard, but do not show up in public DNS lookups. Tried removing and re-adding, no effect. NS are set correctly :pensive_face:

Which specifically? As @sjr has shown, all the records in your screenshot work fine.

dig +short em9451.netwall.host
u50463910.wl161.sendgrid.net.

dig +short s1._domainkey.netwall.host
s1.domainkey.u50463910.wl161.sendgrid.net.

dig +short s2._domainkey.netwall.host
s2.domainkey.u50463910.wl161.sendgrid.net.

dig +short _dmarc.netwall.host txt
"v=DMARC1; p=none;"
