Correct, figures I used are from his website.

Correct, and the load on these servers are minimal.

4 RBL's, a couple of sendmail extra checks like badmx, bad helo and of
course no dns checks, greet pause, spf milter and another milter which
does a few very nice tricks, not much spam gets in in the first place,
and MailScanner seems to get 99% of what does. (I say 99% because to
think any setup anywhere gets 100% is being just plain nieve)

as an example, on only one sendmail box for yesterday (courtesy of 
logwatch)...
  MailScanner Status:
         2904073 messages Scanned by MailScanner
         314 Spam messages detected by MailScanner
         27 Content Problems found by MailScanner

Most acceptable values I think.
