RFC8058 specifies that the List-Unsubscribe and List-Unsubscribe-Post headers must be included in the DKIM signature. These headers are widely used and even required for good deliverability on some platforms.
Unless I am mistaken, when you configure a sending domain for DKIM signing, only the headers date, from, to, message-id and subject are currently included in the signature.
Is it possible to simply add the List-Unsubscribe* headers (or even others) into the signature or Mailwizz cannot currently do this?
