http://wiki.dovecot.org/Plugins/Lazyexpunge also does pretty much
that,
although for all mailboxes, not just for INBOX. And it doesn't
automatically expire them.
There's also rsnapshot which I've been using for hardlinked,
incremental backups for a couple years now. Very flexible and has
saved us a couple times.
