bug#8006: 23.2.93; rmail-mime says "Not a MIME message"

[Eli Zaretskii]

It seems like iff a message doesn't have the Mime-Version header,
typing `v' (rmail-mime) in the Rmail buffer signals an error "Not a
MIME message".  Is this expected?  Sounds like a misfeature to me.

Oh, and also the buffer-file-coding-system of such messages is
undecided-unix, not just undecided.

You mean a MIME message with no Mime-Version header?  What mailer sends
that?

No, it was a plain ASCII message with a single-part body.

Yes

What, do you think, should `v' do for non-MIME message?

Show the raw message as it is held in the mbox format.  That's what it
does for MIME messages, right?  In this case, there's nothing to
decode, but the toggle can still be meaningful.

No, it does some funny thing of _almost_ showing the raw message, but
still hiding the mime boundaries (bug#10078).

The toggle would just be equivalent to rmail-toggle-header, so I really
can't see the point of adding such a feature for `v' myself.

But if you want this feature, does this work?
