Going through the spam that I've got access to (and it is a substantial amount allbeit not in the millions of spam per day) I can't seem to associate the spam with chinese urls, and certainly not to the extent that you indicate (90%).
extract hostname from url, dig on hostname, whois on addr, and nine times out of ten the host is in a CN netblock. that's from the spam that gets into my mailbox. let me state AGAIN that what I really want is a plugin that allows for cidr match-lists so that I can also include the handful of non-enforcing hosters in Russia, New York, Florida, etc. One responder also suggested ASN matchlists but I'm not that mad. -- Eric A.
