You're making it much more complex than it needs to be. Since (except for dictionary attackers) spammers generally don't repeat within your Window of opportunity, you don't need to issue a temporary block for more than a few minutes. And for dictionary attackers you can use other means. > Many of my clients *do* work with ppl in Asia.

And many you don't know about may be corresponding with lots of folk in lots of those address ranges as well. And if they don't... well, they may want to start tomorrow. That kind of blocking only works where a mailserver accepts mail for only one very autocratic domain.
