Yup, I could write an MUA, then there'd be scope for a bug, I bet. The
problem with that is that the post to which I replied posited that local
delivery agents could interfere with mutt's use of headers for internal
purposes. That's an entirely different discussion.

Yup, mutt's good stuff. But the post which I queried posited that LDAs
could magically mangle headers which mutt does not insert until _after_
delivery. It is not least the time-travel component which my post
queried. I do not think that you have addressed that with this new
topic of MUA comparison.
