Frequently Asked Questions
What are email headers?
Email headers are metadata attached to every email that record the journey of the message from sender to recipient. They include the sending server's IP address, timestamps, mail server hops and authentication results.
What is SPF, DKIM and DMARC?
SPF (Sender Policy Framework) verifies the sending server is authorised for the domain. DKIM (DomainKeys Identified Mail) uses cryptographic signatures to verify the message hasn't been tampered with. DMARC ties SPF and DKIM together and tells mail servers what to do if checks fail.
Can I find the sender's real IP from email headers?
For emails from Gmail, Outlook and other major providers your real IP is hidden. However emails sent from some mail clients, corporate servers or less privacy-conscious providers may include your real IP in the Received headers.
