Cannot receive the message notification in other IMAP folders using Thunderbird
Follow the instructions to receive the message notification in other IMAP folders using Thunderbird:
From the ‘Tools’ menu, click ‘Options’.
Click the ‘Advanced’ button.
Click the ‘Config Editor’ button.
In the ‘Filter’ box, enter ‘mail.check_all_imap_folders_for_new’.
Double-click the appropriate parameter.
Close the ‘about:config’ window.
With improved IMAP support comes improved Synchronization. Thunderbird 3 now supports e-mail message archiving, meaning that you can now file any message in Inbox into the new Archive folder system. If you archive an e-mail message from Inbox, it will be added to the ‘All Mail’ folder just like it happens in Gmail.
