I would use Postfix, Cyrus IMAP and Horde groupware suite. You can use
OpenLDAP as an addresbook and databases like MySQL or PostgreSQL as a
backend for Horde.

These programs are free, have many features, and are used in big
organisations (you are from Belgian: e.g. Ghent University uses it, I
can bring you in contact with sysadmins there).


The Horde calendar (Kronolith) will have in short a caldav server which
you can access with desktop calendering programms like Sunbird.

With regards,
