Do you use "-push" to send?  I almost think that no one should ever use
that, but some people prefer it; it's very easy to have mail vanish that
way.

But, AFAICT, here's the sequence of events (this hasn't changed between
1.6 and now):

- repl(1) calls the editor
- Once that is done, it calls whatnow (in the same program, as a function)
- If you type "send", it calls sendsbr(), which will call your postproc.
  If the postproc is successful, it will RENAME your draft using the backup
  prefix.  It never deletes it.

Now, if you specify -push AND -unique (don't ask me what that second flag
does, I've never figured that out), before postproc is called it will rename
it to a temp filename.  Even then, though, it will still be around via
the backup prefix.

So I am really trying hard to see how the draft file could completely vanish,
as nothing in nmh will ever delete it (AFAICT).
