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.
|
|
|
|
General architecture
|
|
====================
|
|
|
|
The mail infrastructure is based on a standard MTA-LDA pattern :
|
|
|
|
* Postfix for incoming and outgoing emails ;
|
|
* Rmilter as a filtering interface before delivery (with rspamd and ClamAV) ;
|
|
* Dovecot as a delivery agent and reading (IMAP) server ;
|
|
* Roundcube (or any Webmail) as a user-friendly Web client ;
|
|
* Fetchmail as a client to fetch remote accounts (POP/IMAP) ;
|
|
* Freeposte (Flask application) as an administration interface.
|
|
|
|
|
|
|
|
Running a mail server
|
|
=====================
|
|
|
|
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 files:
|
|
|
|
```
|
|
wget https://raw.githubusercontent.com/kaiyou/freeposte.io/master/docker-compose.yml
|
|
wget https://raw.githubusercontent.com/kaiyou/freeposte.io/master/freeposte.env
|
|
```
|
|
|
|
The ``docker-compose.yml`` file contains instructions about which containers to run and how they will
|
|
interact. ``freeposte.env`` is the main configuration file. You must read it and provide proper configuration before running the server.
|
|
|
|
You will also need to create a data directory. Freeposte will use ``/data``
|
|
as a sane default:
|
|
|
|
```
|
|
mkdir -p /data
|
|
```
|
|
|
|
Otherwise, simply edit the ``docker-compose.yml`` to match your requirements. Finally, you can run your mail server:
|
|
|
|
```
|
|
docker-compose up -d
|
|
```
|
|
|
|
Upgrading the mail server
|
|
=========================
|
|
|
|
First check upstream for changes in the ``docker-compose.yml`` or in the
|
|
``freeposte.env`` files. Update these files, then simply pull the latest
|
|
images and recreate the containers :
|
|
|
|
```
|
|
docker-compose pull
|
|
docker-compose up -d
|
|
```
|
|
|
|
Monitoring the mail server
|
|
==========================
|
|
|
|
Logs are managed by Docker directly. You can easily read your logs using :
|
|
|
|
```
|
|
docker-compose logs
|
|
```
|
|
|
|
Docker is able to forward logs to multiple log engines. Read the following documentation or details: https://docs.docker.com/engine/admin/logging/overview/.
|
|
|
|
Building from source
|
|
====================
|
|
|
|
You can simply build all the containers from source using the ``docker-compose.yml``. First clone the Git repository:
|
|
|
|
```
|
|
git clone https://github.com/kaiyou/freeposte.io.git
|
|
```
|
|
|
|
Then build all the images:
|
|
|
|
```
|
|
docker-compose build
|
|
```
|
|
|
|
Development environment
|
|
=======================
|
|
|
|
The administration Web interface requires a proper dev environment that can easily be setup using ``virtualenv`` (make sure you are using Python 3) :
|
|
|
|
```
|
|
cd admin
|
|
virtualenv .
|
|
source bin/activate
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
You can then export the path to the development database:
|
|
|
|
```
|
|
export SQLALCHEMY_DATABASE_URI=sqlite:///path/to/dev.db
|
|
```
|
|
|
|
And finally run the server with debug enabled:
|
|
|
|
```
|
|
python run.py
|
|
```
|
