    I have been running a 220R (2cpu, 2GB RAM), as a mail server for about
    80 people. Seems more than adequate under normal conditions.

    Recently, I've had a couple of situations where someone running an
    misconfigured notification tool flooded the mail server which bacame a
    DOS attack. The problem has been resolved, but it made me realize how
    vulnerable the mail server is to this type of attack.

    I'm wondering if anyone can cite some experience or give some
    suggestions to reduce this type of vulnerability? Since I am running
    sendmail, I have set a queue and reject load average, but I'd like to
    do more. I don't think the number of people I service requires more
    hardware, but that may be necessary too.

    Thank you for any input.
