Mail Auth Info Viewer is a powerful Thunderbird add-on designed to combat sophisticated phishing and display name spoofing. It analyzes message headers and body content locally, presenting a clear, color-coded dashboard directly on the message view.
Key Features:
Authentication Dashboard: Displays SPF, DKIM, and DMARC pass/fail status with DMARC policy indicators (reject/quarantine/none). Individual DKIM signatures shown with signing domain and selector.
Sender Identity and Alignment: Shows Display Name, Header From, and Envelope From side-by-side. Detects display name spoofing and Reply-To domain mismatches. DMARC alignment (RFC 7489) shown per authentication method, evaluated only for signatures that passed authentication.
Link Safety Analysis: Scans email body for phishing indicators: deceptive link text, dangerous URI schemes (javascript:/data:), embedded forms, IP address links, IDN homograph attacks, URL shorteners, external-only links, and tracking pixels. Trusted link domains can be whitelisted.
ARC Chain Display (RFC 8617): Visualizes the Authenticated Received Chain for forwarded messages with verification status and authentication summary.
Always-Collapsed Panel: The dashboard starts collapsed for every email, showing the status badge and verdict reason tags at a glance. Click to expand for full details.
Shadow DOM Isolation: Closed Shadow DOM prevents HTML email CSS from contaminating the add-on display.
Organizational Domain (RFC 7489): Uses a curated Public Suffix List covering 60+ countries for accurate domain alignment comparison.
Dark Mode: Full dark mode support following system preference.
12 Languages: English, Japanese, French, German, Spanish, Arabic, Korean, Traditional Chinese, Simplified Chinese, Portuguese (Brazil), Russian, Italian.
Privacy First: All processing is performed locally. No external network requests. No data collected or transmitted.
Verdict Philosophy: Only unavoidable situations (e.g., third-party infrastructure) get a green badge. Anything fixable by the domain administrator is flagged as a warning. This makes the add-on ideal for mail administrators verifying proper authentication configuration.
