The Dovecot default configuration can easily be overridden providing a `config/dovecot.cf` file. This file can also be used to specify additional configurations. [Dovecot documentation](http://wiki.dovecot.org/FrontPage) remains the best place to find configuration options. # Debugging To debug your dovecot configuration you can use this command: ```sh ./setup.sh debug login doveconf | grep ``` [setup.sh](https://github.com/tomav/docker-mailserver/blob/master/setup.sh) is included in the `docker-mailserver` repository. or ```sh docker exec -ti doveconf | grep ``` The `config/dovecot.cf` is copied to `/etc/dovecot/local.conf`. To check this file run: ```sh docker exec -ti cat /etc/dovecot/local.conf ```
