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.

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
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
General architecture
|
|
|
|
|
====================
|
|
|
|
|
|
|
|
|
|
The mail infrastructure is based on a standard MTA-LDA :
|
|
|
|
|
|
|
|
|
|
* Postfix with an SQLite database for transport ;
|
|
|
|
|
* Dovecot with an SQLite database for delivery and access ;
|
|
|
|
|
* Spamassassin for spam filtering ;
|
|
|
|
|
* ClamAV for malware filtering.
|
|
|
|
|
|
|
|
|
|
Additional Web UI :
|
|
|
|
|
|
|
|
|
|
* Roundcube Webmail (can easily be replaced) ;
|
|
|
|
|
* Administration UI based on Flask.
