Login to the docker container, check Dovecot log files under /var/log/, we need the detailed error message for troubleshooting.
I have re-run the docker run command. This time it seems to freeze after "fail2ban entered RUNNING state, process has stayed up for > than 0 seconds (startsecs)"

Dovecot service seems ok now. What's the fail2ban error in its log file?
