Rated 4 out of 5 stars

Just what I've been looking for since moving to Mint 12 and disabling the notification pop-up window at the bottom. The only improvement I can suggest is to allow the user to select it to apply to sub-folders too. I only get the desktop notification when an email arrives in my Inbox. Great app though. Thanks!

Hi! You can probably get what you want in 2 ways:
1) (suggested) by creating a message filter using the custom action "get attention" when a new mail arrives into your subfolder;
2) by right-clicking on that subfolder, selecting "properties..." and finally checking "when getting new messages for this account, always check this folder".
Please let me know if you succeed.
Thank you so far.
