Late to the party here but I like this idea from Axigen, the secure  
email server people;

- Axigen 6.1 also features Country Filtering, which enables system  
administrators to determine geographic locations based on IPs and  
create rules accordingly, such as banning or allowing emails sent  
from selected countries.

As an email security company this is one of the techniques we use on  
clients firewalls, not fool proof but  a good tool to have in the kit
