Gmail n'est pas content

Suite au problème décrit ci-dessus:

• ajout d'un enregistrement AAAA pointant sur l'IPv6 du serveur
• mise à jour des PTR pour les IPv4/v6 pointant sur le nom de la machine principale.

J'ai aussi enregistré le domaine sur https://postmaster.google.com/ en espérant que ça aidera.

Je ferme ce ticket, on rouvrira si nécessaire.

2 erreurs reçues aujourd'hui, pour le même compte gmail. Je rouvre le ticket.
