Freeposte.io
Simple yet functional and full-featured mail server as a set of Docker images. The idea behing Freeposte.io is identical to motivations that led to poste.io: providing a simple and maintainable mail server that is painless to manage and does not require more resources than necessary.
People from poste.io did an amazing job at accomplishing this ; any company looking for a serious yet simple mail server with professional support should turn to them.
This project is meant for free software supporters and hackers to reach the same level of functionality and still be able to host a complete mail server at little cost while running only FOSS, applying the KISS principle and being able to fine-tune some details if needed.
General architecture
The mail infrastructure is based on a standard MTA-LDA pattern :
- Postfix for incoming and outgoing emails ;
- Amavis as a filtering interface before delivery (with SpamaAssassin and ClamAV) ;
- Dovecot as a delivery agent and reading (IMAP) server ;
- Roundcube (or any Webmail) as a user-friendly Web client ;
- Freeposte (Flask application) as an administration interface.
How-to run your mail server
Please note that this project is still in a very early stage. Do not use for production!
The mail server runs as a set of Docker containers. These containers are managed
through a docker-compose.yml configuration file that requires Docker Compose
to run.
First, follow instructions at https://docs.docker.com to setup Docker and Docker Compose properly for your system. Then download the main configuration file:
wget https://freeposte.io/docker-compose.yml
This file contains instructions about which containers to run and how they will
interact. You should also create a data directory. Freeposte will use /data
as a sane default:
mkdir -p /data
Finally, you can run your mail server:
docker-compose up -d
