    Hi Geoff,

    Here is my suggestion. The others should feel free to comment/correct.

    I would have *all* of your mail going through a BSD/Linux box en route to an exchange server.
    I am not conformatable with having an Internet facing exchange box. Call me paranoid,
    or call me safe. You could place both servers on the DMZ, but still have no ports
    open to the exchange box. The blackberry installation should not require any ports
    to be open for the incoming traffic. I can't recall the open outgoing ports that
    are needed for the blackberry data service.

    We were very happy with the Blackberry Enterprise software but if they lose
    in their current litigation it might render your client's investment worthless.

    --Greg
