Philosophy
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
The philosophy behind Mailu is very simple and based on applying the
|
|
|
|
|
following principles, with decreasing priority:
|
|
|
|
|
|
|
|
|
|
1. a proper mail server runs only free software
|
|
|
|
|
2. a proper mail server is easy to setup and maintain
|
|
|
|
|
3. a proper mail server offers proper security
|
|
|
|
|
4. a proper mail server has a simple and beautiful user interface
|
|
|
|
|
|
|
|
|
|
Mailu was designed and is kept up to date based on these. Among the
|
|
|
|
|
structuring choices, the following were quite challenging:
|
|
|
|
|
|
|
|
|
|
- Mailu is based on containers (plural) so that any part can be reused
|
|
|
|
|
in separate projects and that updating or swapping any component does
|
|
|
|
|
not require alterations others.
|
|
|
|
|
- Mailu offers mail and does not bloat the default setup.
|
|
|
|
|
Additional features are available but not required.
|
|
|
|
|
- Mailu has a central front container that routes all HTTP and mail
|
|
|
|
|
traffic.
|
|
|
|
|
- Mailu has a Web administration interface that exposes both a Web UI
|
|
|
|
|
and internal API.
|
|
|
|
|
- Mailu authors are all equal in regard to copyright, thus the license
|
|
|
|
|
will remain free unless all contributors agree otherwise.

History
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
Mailu started in late 2014 and was named Freeposte, the Freeposte.io at
|
|
|
|
|
the time. Early Mailu versions were maintained by a french nonprofit
|
|
|
|
|
named TeDomum, the initial purpose being to re-design their free e-mail
|
|
|
|
|
hosting service as Docker containers and add some fresh UI to the mix
|
|
|
|
|
in order to replace old interfaces like PostfixAdmin.
|
|
|
|
|
|
|
|
|
|
At the time, Post.io was one of the most interesting solutions out there
|
|
|
|
|
and was only lacking a free software licence (hence Mailu's initial
|
|
|
|
|
name). Later, around late 2015, Mailu became a public project including
|
|
|
|
|
contributions from third parties.
|
|
|
|
|
|
|
|
|
|
Today, Mailu is running many mail instances, but remains a community
|
|
|
|
|
project, where everyone is welcome to take part.
