ZEG, which stands for "Zero Effort Groupware", is a virtual appliance of SOGo intended to provide a complete out-of-the-box testing environment. SOGo is a collaboration suite (or groupware) with speed and scalability in mind. It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (CalDAV, CardDAV and GroupDAV, vCard, and vCalendar/iCalendar) and thereby enables the use of many clients and the reuse of any existing infrastructure. The appliance is prepared to be imported in VirtualBox but can also used in VMWare.
