Plus de précisions

Suite à une demande de précisions concernant cette histoire de double-licence, j'ai reçu ceci :

Zarafa is a fairly complex product with various subsystems. You probably did not do a test install, but you can compare Zarafa with an entire MS Exchange server, including support for the windows clients. We will open a website for various parts, including the projects using VMime, on the website. Other parts will remain closed source, for example the windows client that connects to outlook. We will also be releasing some other projects on this website (developer.zarafa.com - down at the moment), including our Microsoft PocketPC synchronization code, which for example doesn't relate to VMime.

In the end, it is our goal to release the entire Zarafa package under GPL. However, we are only a small company now, operating mainly in Holland and Germany, and rely on license income from the rest of the product for the time being.

D'après ce que j'ai compris, il y a une partie serveur, dont ils comptent publier le code sous GNU GPL, et une partie cliente (qui elle restera closed source).
