Hi,
I’ve added a record for Dmarc a few days ago, but it still doesn’t work ! Could you please helpp me understand what is wrong ?
Thanks a lot
Nicolas
You have an extra underscore at the beginning of the name. Replace __dmarc with _dmarc

Hi epic.network,
Mosend if confirming the underscore is required. Besides, in both cases, the record doesn’t show up, even with a wrong content. Do you know what could cause this and what I should do in such a case?
Thanks a lot
Nicolas
One underscore is required by the DMARC specification. Two underscores places the record in an incorrect namespace where it will not be found.
I resolved your incorrect record just fine. Maybe you are not performing the correct query.
% dig txt __dmarc.multimediatique.fr
; <<>> DiG 9.16.48 <<>> @1.1.1.1 txt __dmarc.multimediatique.fr

You must change __dmarc to _dmarc if you want to have any chance of your DMARC policy being found.

Wow, good catch! There was a typo indeed.
Also I’ve figured DMARC1 must be written in cap.
Anyway, you’re my savior 
Thanks a lot for your patient and efficient help.
