Email users can typically tell if an email they received is DMARC protected by doing the following:
1. Open the email: Start by opening the email that you received from the sender.
1. View the email header: Next, view the full email header by clicking on the “Show Original” option, “View Source,” “View Full Header,” or “Message Source” depending on the email client used.
1. Look for DMARC records: In the email header, look for DMARC records that specify the policy used by the sender. If the email is DMARC protected, you should see a DMARC record that contains a “p=reject” or “p=quarantine” tag.
1. Check the DMARC policy: Finally, check the value of the “p” tag in the DMARC record. If the “p=reject” tag is present, it means that the sender’s DMARC policy is set to reject all emails that fail DMARC verification. If the “p=quarantine” tag is present, it means that the sender’s DMARC policy is set to quarantine emails that fail DMARC verification.
By following these steps, email users can know if an email they received is DMARC protected.
