Pas de zone DNS et donc pas d'accès MXrecords

--- Problème résolu ---

Bonjour à toutes et à tous,

Mon nom de domaine est thehouseofexcellence.com
J'ai ce nom de domaine chez OVH depuis plus de 10 ans.
Je suis le responsable Administrateur, Technique et Facturation.

Le nom de domaine est hébergé chez OVH.
Les serveurs DNS sont:
ns14.ovh.net
dns14.ovh.net

Je rencontre la problématique suivante :
Pour la zone DNS, j'ai les messages suivants:
Une erreur est survenue lors de la récupération des informations de la zone :
Vous n'avez pas de zone DNS rattachée à ce domaine.

Si j'appuie sur le bouton "Activer la zone DNS", je reçois le message suivant:
Oops ... Une erreur est survenue lors du chargement de la page.

J'ai essayé de réinitialiser les serveurs DNS mais rien n'y fait.

Pendant des mois, cela ne me posait pas de problèmes car je continuais à recevoir mes e-mails sur GMAIL.
Cet après-midi, j'ai voulu investir pourquoi je n'avais pas de Zone DNS et j'ai activé un MX Plan. Résultat: Je ne reçois plus mes e-mails et je reçois le message suivant:

in32.mail.ovh.net rejected your message to the following email addresses:

The address you sent your message to wasn't found at the destination domain. It might be misspelled or it might not exist. Try to fix the problem by doing one or more of the following:

Send the message again, but before you do, delete and retype the address. If your email program automatically suggests an address to use, don't select it.
Clear the recipient AutoComplete cache in your email program by following the steps in this article: Status code 5.1.1. Then resend the message, but before you do, be sure to delete and retype the address.
Contact the recipient by some other means (by phone, for example) to confirm you're using the right address. Ask them if they've set up an email forwarding rule that could be forwarding your message to an incorrect address.


in32.mail.ovh.net gave this error:
: Recipient address rejected: User unknown
