Open-Xchange is using the OSGi architecture to have maximum extensibility and flexibility. Many parts of Open-Xchange Server can be replaced by different OSGi components, which are called Bundles.
If you have further requests, this document describes the Open-Xchange feature prioritization process and the options for partners and customers to either feed feature requests into this process or to order custom feature implementations.
