I have a slightly better idea...


This can be done in a way that requires no file locking (big plus) and
can finally eliminate the goddamn From kludge (big plus).

For the moment, simply doing /var/mail/user/Mailbox would be a win,
though, and would require zero software changes. This could be done,
btw, with a suid program that is automagically called if the directory
doesn't exist -- since it would be a very simple program, it could be
reasonably secure.
