I also sometimes send attachments, but I do use mail-mode, because it
does support attachments: use the mail-add-attachment command to do
that.

Not sure I understand: are you saying that message-mode sends plain
text body of email messages as MIME attachments?

It shouldn't matter.  Why are you bothered by that?

That's not what I see here.  On my system, rmail-mime toggles the
display of the buttons that allow you to show/hide the various MIME
parts of the message.

Yes.

It depends on how people send responses: some send through news
gateway, others through the list server.  The local configuration of
the person who responses also affects that.
