• I will disclose any AI assistance I have used with the information I provide in my report, so that I do not waste the time of humans trying to help me.

👀 What Happened?

Connecting with a mail client fails.
Dovecot fails to check credentials because /run/dovecot/auth-master is owned by docker:docker and permissions are srw------- so not readable/writable by anyone else...

$ podman exec -it mailserver ls -lat /run/dovecot
...
srw------- 1 docker  docker      0 Jan 20 21:34 auth-master
srw-rw-rw- 1 docker  docker      0 Jan 20 21:34 auth-userdb
...

I'm using podman, so not sure where the docker user came from...
