This plugin requires the Perl Module GeoIP2::Database::Reader.
The RelayCountry plugin attempts to determine the domain country codes of each relay used in the delivery path of messages and add that information to the message metadata as "X-Relay-Countries",
or the _RELAYCOUNTRY_ header markup. This will add metadata to the Bayesian filtering process, allowing the Bayesian filters to learn information based on countries.
Private IPs are marked with ** (two asterisks) and IPs not found in database are marked with XX.
