+Mailu is a simple yet full-featured mail server as a set of Docker images.
+It is free software (both as in free beer and as in free speech), open to
+suggestions and external contributions. The project aims at providing people
+with an easily setup, easily maintained and full-featured mail server while
+not shipping proprietary software nor unrelated features often found in
+popular groupware.

-=====
-
-*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.
