Impossible de se connecter à pop3 ou imap avec Dovecot

Les connexions sont refusées sur mon serveur. Note: J'essaie de me connecter à partir de localhost ici.

Commande que j'essaie d'utiliser pour tester:

user@hostname:~$ telnet localhost pop3
Trying ::1...
Trying 127.0.0.1...
telnet: Unable to connect to remote Host: Connection refused

Même erreur lorsque j'essaie avec imap.

Le dovecot wiki suggère de résoudre le problème, mais j'ai déjà essayé les correctifs. J'ai les protocoles ajoutés à la configuration et l'option d'écoute est définie sur *. Ma config est en dessous. Je ne suis pas sûr de ce qui ne va pas ## Fichier de configuration Dovecot

# "doveconf -n" command gives a clean output of the changed settings. Use it

# those. These are exceptions to this though: No sections (e.g. namespace {})

# "proxy::<name>".

Le message Connexion impossible ... connexion refusée suggère fortement que Dovecot n'écoute pas sur le port 110. Vérifiez que dovecot est en cours d'exécution à l'aide de

ps -A | grep dovecot

Si c'est le cas, vérifiez qu'il écoute sur le port POP:

Sudo lsof -i 4 -a -p $(ps -A | grep dovecot | awk '{ print $1 }')

Si c'est le cas, vérifiez qu'aucun pare-feu ne vous empêche.

S'il s'avère que le pigeonnier ne fonctionne pas ou n'écoute pas sur le port POP, vous avez probablement un pigeonnier mal configuré. Examinez les journaux du pigeonnier et du système pour rechercher des erreurs. Examinez la configuration de pigeonnier en sortie par dovecot -n.

Très probablement, vous avez mal configuré la directive protocols ou la directive listen.
