I have read draft-happel-structured-email-00.
I believe that the document is a good base for starting work.

I like that the links to issues have been spread into the document, thank you.
(You might want to use the venue attribute if you are doing kramdown, which
you seem to be using, and the bullet points in a blank line between them)

I'm not pleased with the partial representation idea, although I could
tolerate it as a transition mechanism.

I believe that there are a few classes of systems that ought to be processing
structured emails which are not MUAs.  tripit is one such system.

The Updates: section is too weak, security-wise.
I don't think RFC4021 is anywhere sufficient in security statements.

My preference would be a TOFU/pinned mechanism of SMIME signatures.
(that is: you can Updates: an email if it's signed with the same signer as
the email it updates)
