Unseen messages folder deprecated
The UI can provide a unread messages folder, if the imap server has a folder which contains all messages. The UI will then request 250 messages sort by unseen and remove all seen messages as well as all messages inside the spam or trash folder. This folder will never remove any seen message.

Make sure, that that field is not protected such that the user is able to change that setting. Otherwise, if the admin wants that the folder is always shown, set the above setting to true and leave it protected.
