Please don't.

More important, rmail-mode seems to modify the file.  Dunno if this is
a bug or a feature of rmail-mode.

$ cat [...]/Incoming* > mbox-test.orig 
$ cp -p mbox-test.orig mbox-test.rmail
$ emacs -Q mbox-test.rmail -f rmail-mode # C-x C-s   C-x C-c
$ diff -U1 mbox-test.orig mbox-test.rmail > mbox-test.diff

(As I wont use Rmail, I don't care much, but ...) it seems that Rmail
recoded iso-8859-1 encoded messages to utf-8 without adjusting the
Content-Type header so the resulting mbox file is no longer correct.
(Modifying the Content-Type would also be a no-no IMHO.)

Bye, Reiner.
