# docker-mailserver

[![Build Status](https://travis-ci.org/tomav/docker-mailserver.svg?branch=master)](https://travis-ci.org/tomav/docker-mailserver)

A fullstack but simple mail server (smtp, imap, antispam, antivirus...).  
Only configuration files, no SQL database. Keep it simple and versioned.  
Easy to deploy and upgrade.  

Includes:

- postfix with smtp auth
- courier-imap with ssl support
- amavis
- spamassasin
- clamav with automatic updates

Why I created this image: [Simple mail server with Docker](http://tvi.al/simple-mail-server-with-docker/)

## informations:

- only config files, no *sql database required
- mails are stored in `/var/mail/${domain}/${username}`
- you should use a data volume container for `/var/mail` for data persistence
- email login are full email address (`username1@my-domain.com`)
- user accounts are managed in `./postfix/accounts.cf`
- aliases and fowards/redirects are managed in `./postfix/virtual`
- antispam rules are managed in `./spamassassin/rules.cf`
- files must be mounted to `/tmp` in your container (see `docker-compose.yml` template)
- ssl is strongly recommended, you can provide a self-signed certificate, see below
- [includes integration tests](https://travis-ci.org/tomav/docker-mailserver) 
- [builds automated on docker hub](https://hub.docker.com/r/tvial/docker-mailserver/)

## installation

	docker pull tvial/docker-mailserver

## build

	docker build -t tvial/docker-mailserver .

## run

	docker run --name mail -v "$(pwd)/postfix":/tmp/postfix -v "$(pwd)/spamassassin":/tmp/spamassassin -p "25:25" -p "143:143" -p "587:587" -p "993:993" -h mail.my-domain.com -t tvial/docker-mailserver

## docker-compose template (recommended)

	mail:
	  # image: tvial/docker-mailserver
	  build: .
	  hostname: mail
	  domainname: my-domain.com
	  ports:
	  - "25:25"
	  - "143:143"
	  - "587:587"
	  - "993:993"
	  volumes:
	  - ./spamassassin:/tmp/spamassassin/
	  - ./postfix:/tmp/postfix/

Volumes allow to:

- Insert custom antispam rules
- Manage mail users, passwords and aliases
- Manage SSL certificates
