I disagree. I'm sure if I removed all the measures I've taken on our 
mailserver I would easily surpass the 100+ messages per day thresh hold. 
These measures are not merely limited to SpamAssassin. They include black 
hole lists, requirements that destination must be local, pop-before-smtp, 
reverse host look-up and more. I personally see close to a 95% reduction 
in spam and other users on the server likely see close to 100%

Enter the world of open source, which IMHO has been the most effective
