SYNOPSIS
loadplugin Mail::SpamAssassin::Plugin::RelayCountry
DESCRIPTION
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.
REQUIREMENT
This plugin requires the Geo::IP module from CPAN. For backward compatibility IP::Country::Fast is used if Geo::IP is not installed.
