Added info about using logging to the 'Error reporting' howto.

To disable this behavior, just remove all entries from the :setting:`ADMINS`

setting.

.. seealso::

   .. versionadded:: 1.3

   Server error e-mails are sent using the logging framework, so you can

   customize this behaviour by :doc:`customizing your logging configuration

   </topics/logging>`.

404 errors

----------

    :ref:`exception middleware <exception-middleware>`. If you do write custom

    error handling, it's a good idea to emulate Django's built-in error handling

    and only report/log errors if :setting:`DEBUG` is ``False``.

   .. versionadded:: 1.3

   404 errors are logged using the logging framework. By default, these log

   records are ignored, but you can use them for error reporting by writing a

   handler and :doc:`configuring logging </topics/logging>` appropriately.
