I've created several Gmail "filters" which move messages to its dedicated folders skipping the Gmail "Inbox". I read Gmail messages using Thunderbird IMAP.
Now, when a new message arrive to Gmail and the filter moves it to another folder (like "My family"), in Thunderbird I do not get any notification that there is a new message in "My family" folder. By notification, I mean a feature where Thunderbird makes the folder bold and writes the number of new messages in the brackets.
The only way to know if there is a new message is to open each individual folder and wait for its contents to refresh with the Gmail server.
How can I fix this? Can this be fixed at all?
