Freeposte.io

Simple yet 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.

Running a mail server

Freeposte runs on top of Docker for easy packaging and upgrades. All you need is a proper system with Docker and Compose installed, then simply download the docker-compose.yml and sample freeposte.env, tune them to your needs and fire up the mail server:

docker-compose up -d

For a detailed walktrough, see INSTALL.md. Also, see MANAGE.md for details about daily maintenance of your mail server.
