    What's in the queues? Who are the messages showing up as being from? Are all
    clients using good centrally managed antivirus software, are you using
    Exchange-aware antivirus software?

    Any reason clients are connecting using POP while on the LAN? I wouldn't use
    that...Outlook/MAPI or OWA only. Sort of defeats the purpose of Exchange
    (and all its collaboration features) if you use POP....
