"It's worse." (Han Solo, "Star Wars")

If I block the 'bad' IP addresses being returned by spammer DNS in my
firewall, postfix still sees it as 'no route'. So it's not a solution.
I realize the problem is occurring in postfix, before SA gets involved,
but if anyone has hit and fixed this 'DNS' problem, I'd appreciate some
pointers. I need to have DNS 'recognize' when a spammer DNS returns
'reserved' (10.0.0.0 et al) IP's, and have it tell postfix 'no host'.
