If someone could answer if the following scenario is possible:

I'd like to run BES 5.0.3 + ZCB and ZCS. Is it possible to have mail delivered to the blackberry and then removed from the mail server after the message has been delivered to the handheld? I actually do not want to store mail on the server. Similiar to POP3/Mail client.

We would run about 100 handhelds and e-mail accounts. Each individual user would be responsible for backing up mail on their own blackberry.

Is this possible with a small cache on the ZCB? Could there be a routine that deletes mail on the ZCS, but does not remove the message from the users blackberry?

Sorry, I'm a little new to this, but any advice would be greatly appreciated!
