They are doing reverse engineering to Microsoft protocol and will provide an open MAPI for developers to integrate any mail app to that enviroment. They didn't reach the final stage yet but when it is done, is suppossed that a third party is thinking on develop a maemo flavor. I did lost the URL but I will search it again. I'll post it later.
