    Thanks to Gary & Ryan.  
    Turns out a machine that dials up to our network has his NIC set to (I have sent him a copy of RFC 1918!).  When the Outlook client
    tells Exchange his address, apparently all addresses are included and
    Exchange doesn't bother checking the source address (turn this over to
    vul-dev :-)).
    So, that is why the Exchange server sends the UDP packets to the bizarre
    Many thanks to the Ethereal team too!
    If anyone wants to see the traffic sample, let me know.
    This list is provided by the SecurityFocus ARIS analyzer service.
