Spam Trace 1.0.0
by Dais Watan
Trace the origins of spam emails on a map.
See where an email really came from. Spam Trace analyzes message headers to estimate
spam/phishing risk — fully offline by default.
About this Add-on
Spam Trace inspects the email you are viewing and estimates how likely it is to be spam or phishing. It examines the Received chain and sender route, SPF/DKIM/DMARC authentication results, links in the message (comparing the sender domain with link domains), and brand impersonation patterns, then shows a 0–100 risk score with the reasons behind it and a route map of where the message traveled.
Privacy first: by default everything runs on your computer with no network access. IP-to-country resolution uses a bundled offline database (DB-IP, CC BY 4.0). Optional online lookups (ipwho.is for detailed geolocation/ASN, and the Tor exit-node list) are off by default and ask for permission before they are used.
You can mark a message as "Suspicious Email" (which also sets Thunderbird's Junk flag) or "Legitimate"; the add-on learns from these to refine future scores. High-risk messages can pop up an alert window automatically, and the interface is available in English, Japanese, Chinese (Simplified), Spanish, German, and French.
