"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

The RelayCountry plugin exposes the countries that a mail was relayed from -- turn it on by reading that documentation page, installing the required CPAN module IP::Country::Fast, and uncommenting the 'loadplugin' line in the /etc/mail/spamassassin/init.pre file for Mail::SpamAssassin::Plugin::RelayCountry.
The RelayCountry plugin will add metadata to the Bayesian filtering process, allowing the Bayesian filters to learn information based on countries.
