Ok, au temps pour moi.
Je vais me faire une bonne formation à la lecture des ces logs toujours trop obscures pour moi.

Ok mais pourtant des mails partent bien:

Oct  2 10:35:15 MONDOMAINE postfix/smtpd[27247]: NOQUEUE: filter: RCPT from MONDOMAINE.fr[MONIP]: <wqbjdfooetppypa362@163.com>: Sender address triggers FILTER amavis:[127.0.0.1]:10024; from=<wqbjdfooetppypa362@163.com> to=<dng293@ara.seed.net> proto=SMTP helo=<MONDOMAINE.fr>

Des mails du domaine qui a utilisé mon serveur d'ailleurs "@163.com"

Peut-être un trojan ou un truc de la sorte ?
J'ai fais un "clamscan -r / " et il n'avait rien trouvé !!

J'ai commenté la ligne :

#smtp      inet  n       -       -       -       -       smtpd

Peut-être qu'ils ne pourront plus passés car j'utilise submission et smtps, donc pas vraiment besoin de cela ?

Et bien j'ai un system de login/pass pour les comptes mail, mais tu parles peut-être d'un autre système ?
Tu entends par "laisser 127.0.0.1 envoyer des emails tout seul" car dans la conf postfix il y à:
mynetworks = 127.0.0.0/8 [::1]/128 ??

J'avoue n’être particulièrement pas doué avec ce genre de système d'ou l'utilisation du tuto howtoforge pour l'installation.

Voici le résultat d'un postconf -n:

Peut-être une idée ??

PS: Comment mettre les parties de code entre balise type [code] [/code] pour ne pas faire des postes de 30km.
