            Albert asked what to do if /var/spool/mail dies and every user
    has his own namespace. Well, don't let him play with /var/spool/mail

    Yep. And quite a few mailreaders can work with that. I'm less than sure

    in the kernel might augment it quite fine and in that case it would
    probably work better. Or not...
