The default docker-compose file will set up:
| Service | Why |
|---|---|
| WildDuck | IMAP, POP3 |
| WildDuck Webmail | Webmail, creating accounts, editing account settings |
| ZoneMTA | Outbound smtp |
| Haraka | Inbound smtp |
| Rspamd | Spam filtering |
| Traefik | Reverse proxy with automatic TLS |
| MongoDB | Database used by most services |
| Redis | Key-value store used by most services |
For the default docker-compose file to work without any further setup, you need port 80/443 available for Traefik to get certificates. However, the compose file is not set in stone. You can remove Traefik from the equation and use your own reverse proxy (or configure the applications to handle TLS directly), remove certain services, etc.
No STARTTLS support, only SSL/TLS.
Install Docker:
$ curl -fsSL https://get.docker.com -o get-docker.sh
$ sh get-docker.shInstall docker-compose
$ sudo curl -L "https://github.com/docker/compose/releases/download/1.28.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-composeCreate a new directory and run the setup docker image. The image only copies the default config folder, .env, docker-compose.yml, and edits them for your domain. It does not install anything on the host system.
The setup image takes 1-2 arguments. The domain for your email (e.g example.com), and the hostname where your mail server will be (e.g mail.example.com). They can be the same host, if you host your website on the same server for example.

$ docker-compose up -dConfiguration files for all services reside in ./config. Alter them in whichever way you want, and restart the service in question.
