Sender authenticity

How FOLD verifies DKIM itself, aligns it with DMARC, and what the indicators in the reader mean.

  1. DKIM, SPF and DMARC

    How FOLD verifies DKIM signatures itself and combines them with the SPF and DMARC results of your mail server.

  2. What the indicators mean

    The seal next to the sender, the warning banner and the security inspector, on Mac, iPhone and iPad.

  3. Brand logos (BIMI)

    When FOLD shows a sender's brand logo, where the logo comes from, and which network request it causes.
