Bonjour,

vous avez 2 enregistrements SPF ce qui est une violation de protocole.

Dans votre zone DNS supprimer l'entrée "v=spf1 include:mx.ovh.com ?all"" et garder uniquement "v=spf1 mx mx:ovh.com include:spf.mailjet.com ~all".

Cordialement, janus57

Je dois ajouter que votre 2è SPF est faux :

Vous dites: "v=spf1 mx mx:ovh.com include:spf.mailjet.com ~all"

1) enlevez le mot "mx" qui est inutile
2) et surtout, remplacez "mx:ovh.com" par "include:mx.ovh.com"

Ceci en complément de l'autre enregistrement SPF que vous devez supprimer, comme l'a bien dit Janus57.
