I did this for a while, but somewhere along the line some of those unassigned netblocks got assigned. I didn't discover this until about 6 months after one corporate customer suddenly couldn't send mail to one of their suppliers. Fortunately I had implemented a workaround in the meantime. I've since removed that section of my firewall setup. -kgd -- Get your mouse off of there! You don't know where that email has been!
