DMARC subdomain setup

Hi,
I don’t understand how to setup DMARC for my domain.
I get a error with the www, it only woks without www.

Anyone could help me?
Thank you.

Hi,

Thank you for asking.

DMARC record usually is a TXT type of the DNS record and covers both and is used for example.com (main domain) and sub-domains too. You cannot have multiple DMARC records for a single domain because it would create conflict and confusion to the systems.

When you check online for DMARC existance and validation, you should only check for example.com (without www).

May I ask you to post and share your domain name in bracketed dot [.] notation (example[dot]com) here so we could double-check, troubleshoot and provide some more feedback information about the issue? :thinking:

Some of the useful online tools to check and generate DMARC:

The domain is www[.]vintage-et-custom[.]fr
And here is the dmarcian test.

Attached Cloudflare report

As stated in my above reply about www, DMARC for your domain name is in place, valid and working:

;QUESTION
_dmarc.vintage-et-custom.fr. IN TXT
;ANSWER
_dmarc.vintage-et-custom.fr. 3600 IN TXT "v=DMARC1; p=reject; rua=mailto:[email protected],mailto:[email protected]"
;AUTHORITY

Ok thank you.
And what do you think about cloudflare report with spf that fails?
