Spam from .cn domains can be mitigated with the right rules and querying multiple lists. I know my users never see .cn domains in their inbox and if I didn't run a blacklist I wouldn't either. Indeed, spam with .cn URIs really doesn't appear to be a problem at all. They are well covered by

Hi! How does that simplify the problem? The difficulty is in getting data about when a domain was created. I thought the problem was in getting data for recently created domains, not all domains. If it's a problem with all domains, this won't help at all. If you rely on whois data, and
