    <title>Administering Disk Space</title>

    <para>
        The maximum number of registered user profiles is limited
        inside the server computer, based on the maximum disk space
        the server computer confines to such purpose. For example,
        consider an environment where users can get registered
        themselves using a web interface. In this case the web
        interface must know how much disk space is available before
        proceeding to register new mail accounts inside the server
        computer and this way preventing any disk writing when there
        isn't enough free space on disk to perform a new user
        registration.  Considering the server computer has confined
        1GB of disk space to handle the mail service (e.g., mail
        queues, mailboxes, etc.) and each user mailbox is 10MB, it
        will be possible to provide self-registration through the web
        interface for 100 users in total.

        Another measure related to save disk space might be to remove
        unused user accounts and their related files (e.g., mailboxes)
        from the server computer. For example, consider an environment
        where user accounts are automatically removed from the server
        computer when they don't establish a connection with the
        server computer in a period greater than 7 days since the last
        valid connection established to the server computer.  Once the
        user account is removed, it is no longer functional of course,
        and the person whom lost the account will need to create a new
        one, assuming it want to have access to the mail service
        again.
