Hello

Please forgive my stupidity.  Is it possible using SpamCop mail to blacklist 
any mail originating in or relayed through any domain in China?

Many spammers utilize China as an intermediary, it seems, and many Chinese 
postmasters refuse SpamCop reports.  I don't know anyone in China, so it's 
unlikely I'd lose anything but spam by doing this.

Is this feasible?

Thanks in advance.
