Treat sub folders the same way as Inboxes

Hi there.

My email provider supports alias addresses. To make things clearer, I created a rule on the server to move emails with an alias as the destination to subfolders of the inbox with the alias name.

Unfortunately, I have noticed that emails arriving in those subfolders do not trigger a notification. Furthermore, they are not displayed in “All Inboxes.” Is there any way I can fix this?
