Very.  We have a single Linux box facing the Internet which
runs everything through postfix, amavisd, and clamav to weed out
the phishing and worms that attack the Microsoft virus, Windows,
then hands off messages that pass to the internal cluster using
round-robin DNS as the poor-mans load balancer.  This box runs
with a load average less than 1.00 most of the time, rejects
close to 2 million messages a day on IP related tests, passing
about a half-million through to the internal servers which do the
spamassassin checking and delivery to the user's mail stores.
