 1. One of the elements of this design which I didn't appreciate at first is that since the config is entirely file-based, **setup.sh** can be run on any container host, provided it has the shared data mounted. This means that even though docker-mailserver was not designed with docker swarm in mind, it works perfectl with swarm. I.e., from any node, regardless of where the container is actually running, you're able to add/delete email addresses, view logs, etc.
