docker-mailserver: [BUG] fresh bare-domain installation, not able to auth - dovecot

Miscellaneous first checks

• I checked that all ports are open and not blocked by my ISP / hosting provider.
• I know that SSL errors are likely the result of a wrong setup on the user side and not caused by DMS itself. I’m confident my setup is correct.

Affected Component(s)

dovecot

What happened and when does this occur?

fresh setup (bare/naked-domain-setup)
configured external certs for my base-domain -> mydomain.org (looks like that is not a issue here)
create a user
try to login with thunderbird
password-check timeout (login not successful)

see the logs

What did you expect to happen?

login successful

How do we replicate the issue?

for bare-domain, i configured 2 things beside default:
 - in `docker-compose.yml` # before `domainname:` and set `hostname: mydomain.org`
 - create `config/postfix-main.cf` and add `mydestination = localhost.$mydomain, localhost`

1. fresh setup (bare/naked-domain-setup)
2. create a user (username `test` password `password`
3. try to login with thunderbird
