I am the assigned ARTART reviewer for this document.  I'm very experienced in
email, and have some experience in the use of encryption.  While I haven't read
this entire document before, I've had in-person conversations with the authors
about it a few times!

It's very well written, and does and excellent job of calling out future work
and laying out the complete problem space.  In that way I think it's a very
valuable document, and as an informative document it should be published.

I do have some concerns about the implementability (particularly, as already
called out in another review, the "strip things which aren't secure enough when
quoting for reply" which will likely make users feel there's something wrong
with their client).  Will client authors refer to this document when designing
things?  Maybe.  It's better than not having anything.

With my "ART Area" hat on, there are no conflicts here with other documents or
with work happening in ART.

I recommend publishing this document.
