Salut à tous,

Je viens de recevoir un message de la part du NOC m'indiquant que mon serveur était Openrelay. Pouvez vous m'aider car je ne vois pas trop ou chercher ni quoi chercher. Tout ce que je souhaite faire c'est recevoir des mails et en envoyer via le wbemail ou via les sites web hebergé sur la machine. Pas d'accés SMTP depuis l'extérieur.

Voici le message que j'ai recut :

ZoneAlarm prevented a remote computer from connecting to port 21 on your computer. This connection attempt was probably a port scan trying to find unprotected FTP (File Transfer Protocol) servers.
