OK - I think I have it working. I'm testing it now. Here's my code, but
someone could clean it up some and do it right.
What this does is go through all IP addresses in the Received headers to
see if any of them are blacklisted the message is caught. This allows
you to apply blacklists to mail forwarded to your spam filter.
Again - someone clean this up and do it right. This could be a real
advancement in stam filtering
