Je dispose d'un serveur sur lequel je veux configurer un serveur de messagerie pour me permettre de recevoir et d'envoyer des e-mails depuis mon domaine. Actuellement, j'ai un problème où je suis autorisé à envoyer des e-mails depuis le serveur, mais selon les journaux, je ne suis pas autorisé à recevoir des e-mails de tout fournisseur autre que mon propre réseau.
Je suis en train de suivre ce tutoriel, qui montre comment configurer un serveur de messagerie en utilisant Postfix, Dovecot et MySQL en tant que backend (ici).
