Privacy on BB MMS questions

Hi All, I'm totally new to this so be gentle...:)

I have a BB 8800 on Vodafone with my current employer & have just managed to set up MMS. I am concerned as to how private MMS is & whether the messages are logged anywhere?

I have done some reading & searches on the net & have noticed that it has a lot to to with BES or BIS now when I go into Manage connections>Services Status>Blackberry Enterprise Server it is showing as Not connected.

Does that mean I amon BIS & my messages are reasonably private and cannot be viewed by an administrator?

Please help.:confused:
