    <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.
