 * 
 * Ingo works purely on a preferred mechanism for server selection. There are
 * a number of properties that you can set for each backend:
 *
 * driver:       The Ingo_Driver driver to use to get the script to the
 *               backend server. Valid options:
 *                   'null'       --  No backend server
 *                   'timsieved'  --  Cyrus timsieved server
 *                   'vfs'        --  Use Horde VFS
 *
 * preferred:    This is the field that is used to choose which server is
 *               used. The value for this field may be a single string or an
 *               array of strings containing the hostnames to use with this
 *               server.
 *
 * hordeauth:    Ingo uses the current logged in username and password. If
 *               you want the full username@realm to be used to connect then
 *               set this to 'full' otherwise set this to true and just the
 *               username will be used to connect to the driver.
 *
 * params:       An array containing any additional information that the
 *               Ingo_Driver class needs.
 *
 * script:       The type of Ingo_Script driver this server uses.
 *               Valid options:
 *                   'imap'      --  IMAP client side filtering
 *                   'procmail'  --  Procmail scripts
 *                   'sieve'     --  Sieve scripts
 *
 * scriptparams: An array containing any additional information that the
 *               Ingo_Script driver needs.
