People using snail mail have little or no trouble understanding the

I basically agree with your points, but unfortunately the analogy
between email and snail mail breaks down in some places. For example,
in snail mail, people actually see the envelope. In email, they
do not. So care must be taken when comparing the two.
Existing email user agents might blur the distinction between these, but
this is a user interface problem rather than a protocol problem. And
user interfaces _will_ have to adapt to take advantage of email
authentication, because email authentication creates new conditions that
users will need to be able to distinguish from existing conditions.
Agreed. MUA support will be critical for any authentication system
to work successfully in the long term.
