/**
|
* 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.inc.php to enable the user option
|
* The user option can be hidden and set globally by adding 'use_subscriptions'
|
* to the 'dont_override' configure line:
|
* $config['dont_override'] = array('use_subscriptions');
|
* and then set the global preference
|
* $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.
