It's not possible. (Not entirely sure why this misinformation continues to perpetuate itself in this forum.)
Incoming BIS messages cannot
be audited by a corporate BES.
Outbound BIS messages can be, if they are forced to be routed through BES.
In this case, the outbound message will actually be sent by the BES email account, not the BIS account. The BES admin can enforce this behavior via IT Policy.
