Freeposte.io

Simple yet functional and full-featured mail server as a single Docker image. The idea behing Freeposte.io is identical to motivations that led to poste.io: even though it looks like a Docker anti-pattern, single upgradable image running a full-featured mail server is a truly amazing advantage for hosting mails on modern cloud services or home-brewed Docker servers.

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.

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.

All components are monitored by supervisord.

TODO

The project is still at a very (very !) early stage. This is more of a roadmap than a proper TODO list. Please poke me or pull request if you would like to join the effort.

• Import vmm configuration files and get a simple postfix/dovecot running with SQLite.
• Add support for spamassassin.
• Add support for clamav.
• Draft a Web administration UI.
• Implement basic features from the free (as in beer) poste.io.
• Start using on a couple production mail servers.
• Implement some fancy features.
