Using global ACLs gets you closer at least. You can define:
acl = vfile:/etc/dovecot/acls
Then having /etc/dovecot/acls/.DEFAULT probably does something.. But I
don't remember if it applies to all mailboxes or just those on the
root level or what. I should look into this some day and make all of
them possible. :)
