Zarafa Mailserver

It’s hard to explain how much work it is to setup your own private state of the art private mail service. The list of components to care of might be pretty scary. But from my own expirience I can tell, it’s possible!

That’s why I decided to write some tutorial about this and share my knowledge. My final objective is to show how you can setup and run a mailserver keeping your mails at home and letting a smarthost handle transfers and checks.


For the start lets have a look on the list of components:
