How can I know if an email sender is spoofed?

    Overview

    There is no 100% guarantee. However, there are some good clues.

    Mailgun provides DKIM and SPF verification for incoming mail, which is shown in the MIME headers once spam filtering is enabled in the Control Panel. This way you can at least know if the message is coming from an authenticated server.
