Email Header & Security Analyzer
SPF, DKIM & Routing Path Inspector
SPF & DKIM Check
Verify the sender's identity by inspecting SPF authorizations and DKIM cryptographic signatures found in the headers.
Hop Analysis
Trace the exact path an email took from the origin server to your inbox, identifying every intermediate mail server.
Delay Tracking
Identify where emails are getting stuck by analyzing the timestamp differences between various routing hops.
Spoofing Detection
Uncover the true "Return-Path" and identify discrepancies between the visible sender and the actual mail relay.
Why Analyze Email Headers?
Email headers are the hidden metadata attached to every message. While your email client hides them for a cleaner look, they are crucial for Phishing Investigation, Deliverability Auditing, and Technical Troubleshooting. By looking at the raw metadata, you can bypass spoofed display names and see the technical reality of how a message was handled.
Key Takeaways
- Verify Authenticity: SPF, DKIM, and DMARC are the three pillars of modern email security.
- Bottom-to-Top Logic: The oldest server (origin) is typically listed at the bottom of the `Received` list.
- Detect Forgery: Spoofed "From" addresses can be exposed by checking the `X-Sender` or `X-SID-PRA` headers.
