haraka-plugin-geoip is a Haraka mail‑server plugin that looks up the sender’s IP address in MaxMind GeoIP databases (via either the `maxmind` or `geoip‑lite` npm modules) and adds geographic data—country, region, city, coordinates, ASN, and optional distance from your server—to the connection results and logs. It’s aimed at mail administrators who want to use location information (e.g., distance thresholds) to help filter spam and generate informative headers.
