What is Postfix Admin?

Postfix Admin is a web based interface to configure and manage a Postfix based email server for many users. Features include support for virtual domains and aliases, quotas, and vacation/out-of-the-office messages. It requires PHP, Postfix and one of MySQL, PostgreSQL or SQLite.

How to use this image

No config.local.php / no existing setup

If you do not have a config.local.php, then we fall back to look for environment variables to generate one.

$ docker run -e POSTFIXADMIN_DB_TYPE=mysqli \
           -e POSTFIXADMIN_DB_HOST=whatever \
           -e POSTFIXADMIN_DB_USER=user \
           -e POSTFIXADMIN_DB_PASSWORD=topsecret \
           -e POSTFIXADMIN_DB_NAME=postfixadmin \
           --name some-postfixadmin \
        winamd64/postfixadmin

POSTFIXADMIN_DB_TYPE can be one of :

• mysqli
• pgsql
• sqlite

Note: An SQLite database is not recommend but used as a fallback if you do not have a config.local.php and do not specify the above variables. Do not forget to add a volume for the SQLite path.

You can also specify a POSTFIXADMIN_SETUP_PASSWORD environment variable.

If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:

$ docker run -e POSTFIXADMIN_DB_TYPE=mysqli \
           -e POSTFIXADMIN_DB_HOST=whatever \
           -e POSTFIXADMIN_DB_USER=user \
           -e POSTFIXADMIN_DB_PASSWORD=topsecret \
           -e POSTFIXADMIN_DB_NAME=postfixadmin \
           --name some-postfixadmin \
           -p 8080:80
        winamd64/postfixadmin

Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.

Existing config.local.php

$ docker run -v /local/path/to/config.local.php:/var/www/html/config.local.php \
           --name some-postfixadmin \
           -p 8080:80 \
        winamd64/postfixadmin

... via docker compose

Example compose.yaml for postfixadmin:

services:
  db:
    image: mysql:8.0
    restart: always
    environment:
      MYSQL_RANDOM_ROOT_PASSWORD: 1
      MYSQL_DATABASE: postfixadmin
      MYSQL_USER: postfixadmin
      MYSQL_PASSWORD: example

  postfixadmin:
    depends_on:
      - db
    image: postfixadmin
    ports:
      - 8000:80
    restart: always
    environment:
      POSTFIXADMIN_DB_TYPE: mysqli
      POSTFIXADMIN_DB_HOST: db
      POSTFIXADMIN_DB_USER: postfixadmin
      POSTFIXADMIN_DB_NAME: postfixadmin
      POSTFIXADMIN_DB_PASSWORD: example

Run docker compose up, wait for it to initialize completely, and visit http://localhost:8080 or http://host-ip:8080 (as appropriate).
