Comment 3 for bug 733488

If I'm correctly informed there is already one other Thunderbird add-on out there that lets you chose whether you want to be informed about every e-mail or just mail in your inbox.

I would really like to see that feature in the bundled add-on as the current behaviour of indicating for all folders is really not working with my mail organisation.

My set-up is a google-mail account which collects my mail from a couple of other accounts via pop3 and puts them not only into the inbox but also tags them according to the account they have been fetched from. In an imap-client such as Thunderbird this translates to the new mails being in two folders.

As the plug-in is working right now, that means I get TWO notifications for ONE e-mail. And even if I read the mail in the inbox and it gets automatically marked as read in the account-specific folder by google, the notification for the second "copy" of the mail only goes away when I actually open it within that folder.

That behaviour is pretty annoying and I would love to see a way to fix this issue. I prefer Thunderbird over Evolution in general, but at least in evolution the notifications worked as I intended them to work.
