quelque soit le client utilisé (roundcube, K9mail, spark sur android, thunderbird sur Fedora), je suis confrontée à des "undelivered mail" sur certaines boites de messageries. Depuis bien longtemps sur une adresse (d'un domaine perso hébergé chez gandi à priori) depuis plus d'un an. Pas de façon systématique (mettons 8 fois sur 10)
