J'ai suivi ce tutoriel : http://flurdy.com/docs/postfix/index.html
Pour une raison quelconque, même après m'être assuré que je l'ai configuré correctement, il n'envoie pas de courrier à des domaines externes. Il peut toujours en recevoir, mais l'envoi donne ce résultat :
postfix/smtpd[26338]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <xxxx@gmail.com>: Relay access denied; from=<user@domain.com> to=<xxxx@gmail.com> proto=ESMTP helo=<domain.com>
J'ai activé TLS, ainsi qu'amavis. La désactivation de l'un ou l'autre (ou des deux) ne change rien. Je peux également envoyer le message à mon propre domaine, et il arrivera correctement.
Voici mon /etc/postfix/main.cf :
