Hi again.

I stated this out in one of my earlier post, but i will
make it even more clear:

Open-Xchange provides currently a collaboration server, several 
extensions and frameworks. We are focused on functionality
and features for the users and customers. To get this functionality
we are using several libraries - you can see the list in out INSTALL
file. Now the question came up if OX can build by using only "free"
software tools and libraries.

We can help to make such an implementation happen, but our
focus is the solution and the features. Thats why we have not
ask for methods. Now, if there is a strong demand and the GNU 
Classpath developers are scheduling the complete implementation
of the required classes and methods for one of the next GNU Classpath
javamail API releases, we should have some conversation how this can be
implemented in a very easy way (like some kind of configure option)
to support it (of course we must keep an eye on the effort ;-).

And to avoid any rumor, this strategy is part of our general
developing concepts. We do not reinvent wheels we are using
existing infrastructure wherever it fits our needs.
