A few years ago, I couldn't.... it was a temporarily viable way of blocking 
a lot of zombie botnet crap.
I haven't checked lately, but if I can disregard the advice in my .sig for 
a second, I doubt it does much good anymore... Unforch, I don't have the 
time to actually profile it.

It's a way of breaking SMTP in such a way that will slow down valid mail 
delivery.
