The final release of Version 3.0 of Kolab, launched on Tuesday, features a new web client, based around Roundcube. 3.0 is designed to integrate more easily with user directory setups and to offer improved scalability, allowing all functional components of Kolab to be scaled separately. There is also a new unified command line for admin tasks.
Server components have been rewritten for the 3.0 release. The Kolab daemon now supports mail-flow monitoring, enforces recipient policies, quota and can be extended with Python modules. These modules can handle emails on the fly, allowing uses such as adding corporate footers or in-line translation of emails. Kolab now uses the 389 Directory Server by default, but still supports OpenLDAP.
