Just a thought:
What'd probably work these days to 'punish' or, more pc, help

since so many systems these days will err out an smtp connection from
a box with no reverse DNS, but would still let it browse web pages. etc.
What about clients with dynamic ip address?
And these probably account for majority of zombies...
P.S. Yes, I know you could set inaddr dynamically and even integrate it
with dhcp, but how many ISPs do you actually know that have done it?
