However, unless sender and receiver verify the authenticity of each others'
certificates, you don't gain anything regarding trustworthiness of the mail
transfer: You have no idea who's going to be able to decrypt the email or
who actually sent it.

I don't see a big advantage over unencrypted, unauthenticated email. For
someone to be able to intercept that, she needs to hijack a TCP session
(disregarding MTAs enroute here). If she's able to intercept a TCP session,
she can also present a 'false' certificate.
