Dockerized mail stack:
- Postfix (SMTP);
- Dovecot (IMAP/POP3);
- Postfixadmin (Mail accounts manage);
- Roundcube (IMAP Client);
- PostgreSQL (DB).
Latest docker (1.13.0 or greater):
curl -s https://get.docker.com/ | sudo sh
Docker-compose (1.13.0 or greater):
sudo pip install docker-compose
Ensure that the iptables firewall is not blocking any of the standard mail ports:
- 25
- 465
- 587
- 110
- 995
- 143
- 993
- 80/8080
If you want to recieve email you have to configure DNS. Like this:
example.com MX 10 example.com
example.com MX 10 1.2.3.4
mail.example.com MX 10 1.2.3.4
Check docker-compose.env file to change or revise default variables:
DOMAIN=example.com
MAILNAME=smtp.example.com
MY_NETWORKS=172.16.0.0/15 192.168.0.0/16
LANG=en_US.utf8
DB_NAME=mail
USER_NAME=mail
USER_PASSWD=eeheiThoh2mohjou
POSTGRES_PASSWORD=oejoojo9eimeeloocuCogichoove4oho
PG_PASSWD_FILE=postgres:5432:*:usrname:passwd
APACHE_RUN_USER=www-data
APACHE_RUN_GROUP=www-data
APACHE_LOG_DIR=/var/log/apache2
APACHE_PID_FILE=/var/run/apache2.pid
APACHE_RUN_DIR=/var/run/apache2
APACHE_LOCK_DIR=/var/lock/apache2

DEFAULT_HOST=ssl://imap.example.com
DEFAULT_PORT=993

Replace exmaple.com to your own domain:
sed -i 's/example.com/your-domain/g' docker-compose.env
Replace sample password and secret key to your own.
docker-compose up -d --build
http://localhost:8080/postfixadmin
Sample Admin passwd
user: [email protected]
passwd: example12345
Here you can create some mail accounts. Then, you can login with created user/passwd credentials to Roundcube web interface page. Or try sample user:
user: [email protected]
passwd: test12345
http://localhost/roundcube/
