Re : Adez moi à debugger Postfix et SendGrid

Bonjour,

L'erreur est explicite :

Jun 22 12:26:03 ubuntu-s-2vcpu-4gb-intel-sfo3-01 postfix/smtp[40774]: 784DF136EA2: SASL authentication failed; server smtp.sendgrid.net[52.89.19.245] said: 535 Authentication failed: Bad username / password

Ce qui en français donne : le serveur smtp.sengrid.net indique que l’authentification a échoué : nom d'utilisateur / mot de passe erronés.
