Je souhaite configurer le relais postfix sur mon site Web hébergeant SMTP Server, à partir de mon serveur d'accueil. C'est Centos 7, mis en place à l'aide de DNS Dynamic IP et Dynamic DNS. En raison de l'espace limité dans mon site d'hébergement, j'aimerais organiser ma propre boîte aux lettres, tout en utilisant SMTP du site en raison de son IP statique. J'ai configuré mon postfix selon - ce tutoriel .
Cependant, lorsque je testez envoyé un courrier électronique à Gmail, mon email est différé. Où est-ce que je me trompe mal? J'utilise le compte de messagerie à l'aide de Thunderbird et il connecte une amende (StartTLs, Mot de passe normal)

Si vous ne pouviez pas encore résoudre cette erreur, ma configuration est de 99% similaire à la vôtre et que j'avais toutes configurées conformément à celle-ci, mais que vous remarquez simplement à Gmail SMTP Cincarpoint.
Jetez un coup d'œil à ce fil -> https://www.howtoforge.com/community/threads/solved-problem-withouting-mail-from-server.53920/
Il s'est avéré être une bibliothèque manquante dans ma configuration de Debian.
apt installer libsasl2-modules
J'espère que ça aide!
Installez le paquet cyrus-sasl-plain
Pour fournir la méthode de l'authentification SASL Unble.
