Can someeone explain this detailed, which service does what and how are informations transported to the handheld (ports, involved services and so on ) ?
Something I found. It should help you.
The BES connects directly to the mail server (Microsoft Exchange, Lotus Notes, Novell Groupwise) to gain access to the user’s mailbox, calendar, and related data stores. The BES also connects to RIM’s network operations center (NOC) via an outgoing (client-initiated) socket connection on port 3101. Once the connection is established and the identity of the BES is authenticated (a unique authentication key is delivered with every BES) the connection then serves as a two-way tunnel for communication between the NOC and the BES. Since each carrier also connects to the NOC, this enables the NOC to relay data from the BlackBerry to the BES and vice-versa.
MDS is an optional component that acts as a Web proxy server for the BlackBerry devices paired to the BES. With MDS enabled, users can browse the Web regardless of what network or carrier is being used. Page requests get sent to MDS via the BES; MDS fetches the actual page and delivers it to the device for rendering. In the simplest configuration the MDS proxy is also on the intranet and therefore has access to internal servers as well as (by going out through the firewalls) the Internet.
