MailService

Collection of Docker images for full Mailservice: SMTP/TLS + IMAPS + PostGrey + SPAM filter; built using several subprojects.

Build the images:

docker-compose build

Start:

docker-compose up

Wait until the database is initialized and outputs:

postfixadmin-db_1 | 2021-06-10T19:41:31.466095Z 0 [System] [MY-010931] [Server] /usr/sbin/mysqld: ready for connections. Version: '8.0.25' socket: '/var/run/mysqld/mysqld.sock' port: 3306 MySQL Community Server - GPL.

Open in Browser: http://localhost:8080/public/setup.php

Wait for a long time and create an admin.

The configured setup password is test123 — that's good for testing, not for production. To change it, set variable SETUP_PASSWORD in docker-compose.yml to anything else, e.g.: SETUP_PASSWORD: ChangeMe before you open http://localhost:8080/public/setup.php the first time (or delete the database, see below), then follow the instructions on the page and you get a new hash to set in SETUP_DATABASE.

If you use TLS, Configuration parameters are:

IMAP: SSL/TLS (port: 993)
SMTP: StartTLS (port: 578)
SIEVE: StartTLS (port: 4190)

Access rights for the volumes, if on a local filesystem, must be set to: 100:1000

PostfixAdmin

Includes: https://github.com/mwaeckerlin/postfixadmin Includes: https://github.com/mwaeckerlin/postfixadmin-proxy

To upgrade the Postfixadmin by upgrading the image, you need to remove the mailservice/postfixadmin volume:

docker-compose rm -vfs
docker volume rm mailservice_postfixadmin

Completly delete the database (loose al data), rebuild and use the new distribuition:

docker-compose rm -vfs
docker volume rm mailservice_postfixadmin mailservice_postfixadmin-db
docker-compose build
docker-compose up
