Any reason why the imap-listener port is set to 0 and not 143 or commented out?
Have you checked if dovecot is listening on 143?

Greetings,
I was just tasked with rebuilding from scratch the mail server of an NGO, on a brand new Ubuntu 24.04 LTS VPS.
I have copied the whole dovecot configuration to the new server, and now am stuck because:
dovecot IS running, dovecot service status shows no errors, but:
if I try to connect with mutt from my desktop I get "connection refused"
the ufw firewall does allow imap/imaps connections, and there are no errors in its log
even "telnet localhost 143" fails: Trying ::1... Connection failed: Connection refused Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused
I see no related errors in /var/log/mail.log or /var/log/syslog.
output of dovecot -n is pasted below, I only changed the actual domain name to "example.com"
TIA for any pointer, I really need to get this server back online as soon as possible...
