    In my experience, you cannot create a mailbox when connected to a frontend
    server. Your environment with 1 backend makes it seem silly, but in the
    case with multiple backends you would need some way to specify where to
    create the mailbox. In our case, our script randomly picks a backend,
    connects to it, and creates the mailbox.
