One of my users was surprised that her RMAIL mailbox was worldwide
readable.  I know that this topic is somewhat touchy (esp. with
respect to "open" system designs).

Gnu Emacs surprises a lot of users already enough by converting their
Unix mbox file into a BABYL file inadvertently, but even when the
format gets changed it doesn't look nice to change the mail's privacy
silently.  A interactive question could do the job.  If I've enough
spare time (and nobody else has already cared about this), I'll dig
further into this.
