OK, so then you need to have a per-user mail_location for the subscriptions. Something like:

namespace {
 list = children
 location = maildir:/var/mail/public
 prefix = public/
 separator = /
 subscriptions = no
 type = public
}
namespace inbox {
 location = maildir:/var/lib/dovecot/empty:CONTROL=/var/mail/user/%u
 prefix = /
 inbox = yes
}

With the "empty" directory being non-writable, the users can't create any private mailboxes, but with the writable control directory they can store subscriptions there.
