Issue running Dovecot in Docker Container

[Naveen Reddy]

Hello,

We need help with an issue that we are running into when we are trying to
run Dovecot in Docker container.
Also how do we enable debugging for dovecot. Logs doesn't show any info
about the issue.

Below processes are not running when a Director service is started:

dovecot-Dovecot/auth
dovecot-Dovecot/ssl-params
dovecot-Director/lmtp
dovecot-Director/ssl-params
dovecot-Director/imap-login director


Here is the version that I'm running and including the dovecot -n output
below:

bash-4.2# dovecot --version
2.2.36

bash-4.2# dovecot -n
