I was thinking of just using cp and friends, and yes I have done that
to move around my maildirs.

I'm curious if mutt preserves the mtime when doing the mutating
operations I mentioned ie. rethreading or editing after the fact.
Especially in the case of editing, I have serious doubts that mtime
is preserved.  But maybe mutt also creates a fresh message in this
case, my memory is foggy.

I'm also curious what other programs look at the mtime to determine
time delivered. I mean real programs, not your hand written scripts
;-)
