Can someone explain very briefly the way Blackberry's email functions. I'm not looking for nuts and bolts, just answers to some very basic questions:
- Does a Blackberry check with an Exchange server directly, or does it always/ever use an intermediate server?
- If it uses an intermediate server, is that server managed by RIM, or the customer's mobile network operator?
- To configure Exchange email on a Blackberry, do you enter the settings on the phone itself, or via a web interface?
- What other email protocols can Blackberry devices use, and do they (also?) use an intermediate server?
