il la sort d'où la liste de cipher oO

t'as essayé:
telnet localhost 465
ehlo unnati.fr
starttls

?

mais le port 465 est deprecated, c'est submission et pas smtps maintenant et donc le port 587 :)
le port 465 est gardé pour les vieux systèmes de ce que j'ai lu.

smtpd_tls_exclude_ciphers     = aNULL, DES, 3DES, MD5, DES+MD5, RC4, PSK
ca aidera la sécurité ;)
et le disable_vrfy_command ca empêche de vérifier qu'une adresse existe bien pour la spammer après

edit: test ca: openssl s_client -debug -starttls smtp -connect localhost:465

t'aurais peut être un retour plus parlant avec le debug

edit 2: la liste de cipher y a surement moyen de la faire plus sécu et optimisé

Cela fonctionne! :sol:

Pour smtps, j'ai dû commenter la ligne suivante :

Code : Tout sélectionner

-o smtpd_tls_wrappermode=yes
J'ai aussi activé submission et cela fonctionne.

Par conséquent, les ports, 25, 465 & 587 fonctionne. ;)

J'ai bien entendu rajouté ta configuration, merci. :jap:

Lors d'un envoi sur le port 587 cela donne :

normalement si tu utilise ce que je t'ai donné sur ton relay et ton serveur mail, tu peux plus faire de SSLv3.
