The Trend Micro ERS (formerly RBL+) list has netblocks by (purported) 
country of origin; it's been fairly effective for me at work.  You can 
select various IPs by country, or entire countries, and then whitelist 
senders as needed.  I use it in Sendmail with a custom 550 message 
directing legit senders to a web form where they can plead their case. ;)

I suspect it could be plugged into SA rules and scored upon as well.

It is, however a for-pay feed.  I can't recall the pricing offhand.
