<?php
/**
 * Ingo works purely on a preferred mechanism for server selection. There are
 * a number of properties that you can set for each backend:
 *
 * IMPORTANT: DO NOT EDIT THIS FILE!
 * Local overrides MUST be placed in backends.local.php or backends.d/.
 * If the 'vhosts' setting has been enabled in Horde's configuration, you can
 * use backends-servername.php.
 *
 * Example configuration file that enables the Sieve backend in favor of the
 * IMAP backend:
 *
 * <code>
 * <?php
 * $backends['imap']['disabled'] = true;
 * $backends['sieve']['disabled'] = false;
 * </code>
 *
 * disabled: (boolean) If true, the config entry is disabled.
 *
 * params: (array) An array containing any additional information that the
 *         transport class needs. See examples below for further details.
 *
 * preferred: (string) 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.
 *
 * script: (string) The type of script driver this server uses. Options:
 *   - imap:  IMAP client side filtering (POP3 servers NOT supported).
 *   - maildrop:  Maildrop scripts.
 *   - procmail:  Procmail scripts.
 *   - sieve:  Sieve scripts.
 *
 * scriptparams: (array) An array containing any additional information that
 *               the script driver needs. See below for further details.
 *
 * shares: (boolean) Some drivers support sharing filter rules with other
 *         users. Users can then configure filters for each other if they
 *         give them permissions to do so. If you want to enable this feature,
 *         you need to set this parameter to true.
 *
 * transport: (string) The transport driver to use to store the script on the
 *            backend server. Valid options:
 *   - ldap:  LDAP server.
 *   - null:  No backend server (i.e. for script drivers, such as 'imap', that
 *            does not use scripts).
 *   - timsieved:  Timsieved (managesieve) server.
 *   - vfs:  Use Horde VFS.
 *
 *   NOTE: By default, the transport driver will use Horde credentials to
 *         authenticate to the backend. If a different username/password is
 *         needed, use the 'transport_auth' hook (see hooks.php) to define
 *         these values.
