we have 20 regex expressions that block mail directly from a 
reverse dns that "looks" like a consumer broadband connection. 
Then we have to maintain a whitelist on a case by case basis.

The reduction in unwanted email is on the order of 40 or 50
to 1. It obviously is not without its own pain so it may
not be for you. This should discussion should probably be
taken offline or two another list though.
