<?php
/**
* Subscription Options
*
* A plugin which can enable or disable the use of imap subscriptions.
* It includes a toggle on the settings page under "Server Settings".
* The preference can also be locked
*
* Add it to the plugins list in config/main.inc.php to enable the user option
* The user option can be hidden and set globally by adding 'use_subscriptions'
* to the the 'dont_override' configure line:
* $rcmail_config['dont_override'] = array('use_subscriptions');
* and then set the global preference
* $rcmail_config['use_subscriptions'] = true; // or false
*
* Roundcube caches folder lists. When a user changes this option or visits
* their folder list, this cache is refreshed. If the option is on the
* 'dont_override' list and the global option has changed, don't expect
* to see the change until the folder list cache is refreshed.
*
* @version @package_version@
