Since 2.0.0, we support usage of MaxMind GeoLite2 databases to show which country the senders IP address belongs to.
Usage of the MaxMind GeoLite2 databases requires you to register on their website here:
https://www.maxmind.com/en/geolite2/signup
Once registered, go to your account on maxmind.com and access the My License Keys option under Services
Here you can generate a new license key and copy it to your MailGuardian configuration under src/mailguardian/settings/local.py
Here add your license key to the file:
MAXMIND_ACCOUNT_API_KEY = 'PASTE_YOUR_LCENSE_KEY_HERE'
Finally restart the MailGuardian service like this:
sudo systemctl restart mailguardian.service
