Detailed Description

Class for global mail information (e.g.

in main menu). This class should only contain methods for fetching data which is necessary in global parts of ILIAS, e.g. the main menu. We should keep this class as small as possible. Maybe we duplicate some code which already exists in class ilMail, but we need an efficient class.
