## How does docker-mailserver help with setting everything up?
As an _all batteries included_ Docker image, docker-mailserver provides all the required components and a default configuration to run a mail server. On top of that, the [env-mailserver](https://github.com/tomav/docker-mailserver/blob/master/env-mailserver.dist) configuration file allow you to tweak your setup extensively.
The default configuration may _not_ be considered 100% secure, because it aims at supporting all kinds of clients, including older ones not able to use TLS-encrypted connections. It is up to you deciding which kind of transportation encryption to use / enforce.
The [README](https://github.com/tomav/docker-mailserver) is the best starting point in configuring and running your mail server. You may the explore this wiki to cover additional topics.
