=pod

This plugin uses MaxMind's GeoIP service and the Geo::IP perl module to
do a lookup on incoming connections and record the country of origin.

Thats all it does.

It logs the country to the connection notes 'geoip_country'.  Another
plugin can use that value to do things to the connection, like reject,
or greylist.

    my $country =
        $geoip->country_code_by_addr( $self->qp->connection->remote_ip )
            or return (DECLINED);

    $self->qp->connection->notes('geoip_country', $country);
    $self->log(LOGNOTICE, "GeoIP Country: $country");

    return DECLINED;
