IP blacklistée ? Port imap 143 filtered/open
Bonjour,
Je suis face à un problème:
J'ai un serveur avec Dovecot et Postfix dessus.
Depuis mon réseau wifi le port 143 du serveur apparaît 'filtered'.
Il apparaît 'open' lorsque je suis connecté en 3G.
Le problème dure depuis plusieurs jours et empêche mon équipe et moi même de récupérer nos mails.
Qu'en pensez vous ?
UFW:
