ip_restrict plugin
------------------

Simply untar the file in the plugins directory.  To do this, simply use the
following command:

  # tar xzf ip_restrict-0.1.tar.gz

It should retain the directory structure as follows:

  ip_restrict/COPYING
  ip_restrict/index.php
  ip_restrict/INSTALL
  ip_restrict/README
  ip_restrict/restrict.sample.php
  ip_restrict/restrict_functions.php
  ip_restrict/setup.php
  ip_restrict/VERSION
  
Once extracted read the README file for details on how to setup restrictions.  Then
go into your SquirrelMail configuration directory, and run conf.pl, select option 8,
and add the plugin.  Save the configuration and exit.

Creating a restrict.php file
----------------------------
There are two ways to create a restrict.php.  The first is simply rename the sample
file included (restrict.sample.php).  The second is to either create one with your
favourite editor on the server, or use your favourite editor, and ftp (or scp) the
file to the server.  This file must be located in the ip_restrict directory, and
must be readable by the web server.
