sometimes domain not found

[Erwan Le Moing]

Hello,

I've a domain for example something.fr with a mailserver. Everything's working good, but sometimes and only with google mail I've some error of domain not found when sending an email to my domain. Most of the google mail email have no problem.

I think about a dns problem on google servers or hust one server, so it's just random error.

example of error:

---------- Forwarded message ---------
De : Mail Delivery Subsystem <mailer...@googlemail.com>
Date: ven. 21 janv. 2022 à 09:25
Subject: Delivery Status Notification (Failure)
To: <som...@gmail.com>

Adresse introuvable
Votre message n'est pas parvenu à recru...@something.fr, car le domaine ville‐ something.fr est introuvable. Vérifiez qu'il ne contient pas de fautes de frappe ni d'espaces superflus, puis réessayez.

La réponse était :
DNS Error: 40036548 DNS type 'mx' lookup of xn--something-fm6g.fr responded with code NXDOMAIN Domain name not found: xn-- something -fm6g.fr

Someone with an idea or way to contact google tech  ?

Thanks
