    Inbound email flow issue afer incorporating Sophos Email Appliance

    Current setup (without appliance)
    static route outside IP to inside IP (exchange 2003)

    mail flows fine

    proposed setup (with appliance)
    static route outside IP to inside IP (Email appliance) > email appliance forwards to exchange

    Here is the error (sanitized)

    This is the mail system at host
