Bonjour à tous,
je suis actuellement en stage et ma mission est de mettre à jour un serveur mail (datant de 2014-2015) tournant sous debian 5 avec un serveur ldap distant.
Ma solution a été de repartir d’un debian plus récent et de tout réinstallé. Cependant les paramètres ayant parfois changé voir disparu la configuration obtenu ne fonctionne pas notamment la partie sur dovecot.
Vous trouverez ci joint la configuration dovecot et postfix de mon nouveau serveur mail, l’ensemble des paramètres sont définis en fonction de l’ancien serveur mail.
