This is just a suggestion, not a bug report, so no
precise version or platform information should be
needed. I verified that emacs 21.1 has the behavior
I'm complaining about.

A user here noticed that when you use rmail, your mail
messages show up in a read-only buffer; however, when
you use mh-e, the mail messages show up in a writable
buffer, although any modifications you make to the
buffer are lost (I think after prompting the user) when
you show the next message.

Perhaps mh-show-mode should set the buffer read-only.
(mh-display-message might need to be modified to
temporarily turn off read-only mode in order to put in
the message content, of course.)
