I can second the 40-60% figure. I'm running a proof of concept test
server, It acts as a front-end server to approx 65 sites. I just tag it,
bag it, and sent it on. It handles 40-50,000 messages a day.
My graphdefang charts shows approx 50-60% of the total mail traffic is
SPAM using a SA minimum score of 5. when I first started the server in
the middle of September, the SPAM was around 40% of the total mail
traffic.
