Exactly.  This is not the maximum number of message/day, it is what
they've got right now.  I run Mailscanner with SA, DCC, Pyzor, Razor,
special rules, ClamAv, Bitdefender, MailWatch, MailScanner-MRTG and
MailStats on a PII 233, 256 MB machine and I process about 120
messages/day.  My average load is 0.5.  I can't remember who sent this
statistic, but I'm surprised to see the average load is 2-4.  Maybe it
is not a dedicated MailScanner machine.
