O e-mail do meu servidor não pode se conectar ao Outlook ou ao Thunderbird

1

Eu tenho postfix para smtp e dovecot para imap / pop com FROXLOR. Eu configurei corretamente, mas não consigo configurar uma conta nos programas de email do cliente. No Outlook, recebo Log on to incoming mail server (IMAP): Failed to connect to the server. . Eu entendo isso quando tento usar o imap também. Eu não estou usando ssl ou tls, mas apenas para o trabalho, eu tenho que definir starttls para autenticar no Outlook (minha pesquisa diz isso).

Meu main.cf do postfix é:

## General Postfix configuration

Como posso resolver o problema em todos os emails de clientes? No meu localhost funciona. No meu roundcube, também posso enviar e receber emails, mas preciso fazer isso no Outlook ou no Thunderbird.

EDIT 1: meu dovecont -n diz:
