A very sizeable amount of spam (currently 50%) contains .cn domains that
were registered very recently. They keep registering new domains in
order to keep ahead of the URIBL's.

Hi Warren!
It seems then the only way to feed a URIBL fresh .cn domains would be a
spam trap. This proposed URIBL would be extremely easy to build on the

My own volume of spam is too small to do this.

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
