Email Header Analyzer

The header is the technical top section of every email containing the message's route, sender and recipient, and the results of security checks; it is usually accessible via "show original/source".

Each hop is an intermediate server in the delivery path; the delay shows how long the message waited at each step and helps locate slow points.

pass means the check succeeded and is valid, fail means it failed and may be spoofed. If all three pass, the sender's authenticity is verified.
