Depuis peu mon serveur de mails (chez Gandi) ne peut plus joindre des comptes sur Google Mail qui bloque tous les envois qui ne sont pas authentifiés, en vue de combattre le spam. Bien, mais cela ne fait pas mon affaire car ces mails sont parfois destinés à mon médecin. Je joins ci-après une copie du message d'erreur (anonymisé) renvoyé par Google.
