Agreed, PGP/GPG and S/MIME solved this long ago, with the added benefit of end-to-end encryption.
Is it possible to put a PGP/GPG public key in the DNS and have an MUA use it?
Since you've asked; anything is possible[1], and since you're already aware of existing mechanisms (key servers) for distributing public PGP/GPG keys; I see what you're getting at, the verification of which is up to the end-user rather than a independent "trusted" third party, or by exhibiting the control of a domain via publishing in the DNS. [1] Although it's entirely possible, I'm not aware of any implementation and without thinking it through more thoroughly I'm unsure why one would want to.
