What is SPF and DKIM?

SPF verifies sender IP authorization. DKIM adds digital signatures. Both prevent spoofing.

How can I trace the sender of a suspicious email?

View the full email headers and look for the originating IP in the earliest 'Received' header. Use an IP lookup tool to identify the sender's approximate location and ISP.

What does the Received header in an email tell me?

Each 'Received' header shows one server hop the email passed through, including timestamps, server names, and IP addresses. Reading from bottom to top reveals the email's complete delivery path.
