Or you could just use S/MIME. DKIM wasn’t designed for the purpose the author describes. But S/MIME works great for this purpose.

Alas, S/MIME is relatively complicated and can't really be used by the general public without re-teaching everyone how email work (lost keys will be a support nightmare). But yeah, S/MIME signing is incredibly useful for the specific purpose the article suggests.
