The short answer is you can't reliably, but if you are prepared to
accept a small risk of collateral damage block the zones of the internet
that are littered with open mail relays and dozy sysops - notably:

*.hk
*.kr

Ask on d.i.s.turnpike for details of a custom rule to do it.

I think Custom rule reject /^X-Trace.*\.kr/h
or something like ought to do it NB UNTESTED

It will also bin anything posted by legit Hong kong users into u.r.g
Try it at your own risk!
