Mailu
|
|
|
|
|
=====
|
|
|
|
|
|
|
|
|
|
*This project used to be named Freeposte.io, the name was changed back in
|
|
|
|
|
October 2016.*
|
|
|
|
|
|
|
|
|
|
Simple yet full-featured mail server as a set of Docker images.
|
|
|
|
|
The idea behing Mailu 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
|
|
|
|
|
=====================
|
|
|
|
|
|
|
|
|
|
Mailu 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 ``.env``, tune them to your needs and
|
|
|
|
|
fire up the mail server:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
docker-compose up -d
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
