To identify a spoofed email from the header, look for discrepancies in the “From” and “Return-Path” fields. Check for mismatched domain names or IP addresses in the “Received” lines, which indicate unusual routing paths. Additionally, scrutinize the “Reply-To” and “Return-Path” fields for inconsistencies. If in doubt, verify the sender’s email address independently.

The email header provides valuable information about the email’s origin, route, and transmission details. It includes the sender’s and recipient’s email addresses, the date and time the message was sent, information about the mail servers involved in the message delivery, and message IDs. This data can help in troubleshooting email issues, tracking email sources, and detecting potential spam or phishing attempts.
