We've got a Sun 220R with 2x450Mhz processors and 1GB RAM running
sendmail, MailScanner, SpamAssassin, and Sophos.  We normally average
about 25k messages per day, and the load average is generally between
one and three.  During the Sobig outbreak, those numbers jumped up to
about 30-40k messages per day, and the load average was between about
three and seven.  The increased load didn't seem to affect the delay
time though, as we were seeing values in the four to ten second range on
average.

We don't have anything very fancy set up for sendmail.  We do use
spamhaus  for RBL's, and the access_db to whitelist/blacklist relays.
 Same with MailScanner.  Other than some custom rules in the
spam.assassin.prefs.conf, it's pretty much plain vanilla.
