    Why use the central mail server? If the logserver's MTA contacts the
    admin workstations directly, you have removed one point of
    failure/compromise. This MTA still won't have to listen on the
    network, just be intelligent enough to send mail to the right host.
    
    An attacker would have to compromise most of the admin stations as
    well to keep an alert from reaching anybody. Maybe the loghost should
    ring an old fashioned alarm bell if a certain percentage of admin
    stations are not reachable for some time (to detect DoSsing). Will
    also freak out the folks when the whole network is down <eg>.
