Docker-Mail

Dockerized mail stack:

Postfix (SMTP);
Dovecot (IMAP/POP3);
Postfixadmin (Mail accounts manage);
Roundcube (IMAP Client);
PostgreSQL (DB).

Requirements

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

Before you start

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

Variables

Check docker-compose.env file to change or revise default variables:

Postfix

DOMAIN=example.com
MAILNAME=smtp.example.com
MY_NETWORKS=172.16.0.0/15 192.168.0.0/16

Postgres

LANG=en_US.utf8
DB_NAME=mail
USER_NAME=mail
USER_PASSWD=eeheiThoh2mohjou
POSTGRES_PASSWORD=oejoojo9eimeeloocuCogichoove4oho
PG_PASSWD_FILE=postgres:5432:*:usrname:passwd

Roundcube / Postfixadmin

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
APACHE_LOG_DIR=/var/log/apache2

Roundcube config

DEFAULT_HOST=ssl://imap.example.com
DEFAULT_PORT=993
SMTP_SERVER=tls://smtp.example.com
SMTP_PORT=587
DES_KEY=angahth3ki7shaeTie7queibeSaeyugi

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.

Run

docker-compose up -d --build

Check Postfixadmin web interface

http://localhost:8080/postfixadmin
Sample Admin passwd
user: admin@example.com
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:

Roundcube

user: test@example.com
passwd: test12345
http://localhost/roundcube/
