Then the only real string I can work from is that received-by line and if that 
line has a high score by itself.  The idea being that, like viagra, it too will 
quickly approach 1.00 and at some threshold I would opt to simply reject 
delivery at the door rather than run it through all the delivery processes to 
only have it whacked by bogofilter.
