To help the understanding of the Zarafa architecture, a schematic displaying of the technical construction behind Zarafa is shown here. When you want to install Zarafa, here you can see how the linux server and Zarafa are integrated, as well as how Zarafa collaborates with Windows and Outlook. All blue parts in the visualization are developed by Zarafa.
There is a more extensive description of this model available in the Server manual.

The Zarafa Summercamp 2010 came to an end on Friday the 18th of June – a 2 day conference which again drew a lot of interest, cementing its position at the top of European open source vendor events, through even higher attendance numbers than in 2009 and intensified contributions of community members and partners.
At the second day of its Summercamp, the Dutch mobile messaging and collaboration specialist Zarafa launches an integration framework that will give the open source community and commercial integrations with Zarafa's Collaboration Platform a next big boost.
