Composite trust analysis

Domain, URL & Email Trust Checker

This version stops pretending DNS alone is enough. It combines DNS and mail-auth posture, website behavior and hardening, RDAP registration signals, and optional raw email-header analysis for message-specific checks.

Paste a domain like example.com, an email like [email protected], or a URL like https://example.com/pay. This hits /api/dns?mode=analyze, which runs the full DNS, HTTP, and RDAP analysis through your existing dns.js route.
This tool is materially better than a plain DNS checker, but it still does not prove that a sender, invoice, or site is safe. It shows visible technical posture, message-specific authentication when headers are pasted, and what still remains unknown.
