Currently it's only possible to select which accounts or special folders are included in the new-message-count.
As already mentioned in Issue 105 on the old issue list, this is not as useful as selecting folders to include.
I myself am subscribed to various mailing list and don't want them to be included in the counter in my icon. These mailing lists each have their own folder they get filtered in. IMHO this is a very common practice and affects many users.
Hi, I knew this request would pop up sooner or later. Nevertheless, this is a tough job, as it means re-implementing the folder pane in the pref window, or try to extend it (as extra-folder-columns does), and try to keep the preferences in sync with folders, and tune the message counting...
Honestly, I don't anticipate working on it soon. But I keep the request in the to-do list, because I agree that this feature is important.
Until then, a possible dirty workaround for an IMAP account could be to isolate mailing lists' folders by:
I solved this by utilizing the favorite folder flag. I've created a patch (see pull request #45) that let's you choose whether to count all mails or only those in favorite folders.
Thank you very much. This can more or less also be considered as a fix for issue #44.
Firetray now provides a only favorite folders option which should do the trick: only favorite folders are counted in.
It would be nice if you could test it and provide feedback. I'll close this issue, but feel free to re-open it if necessary.
As explained in #45, it should be possible to replace the favorite folders trick by a proper firetray include item in folder's context menu. We can try to look into that later if needed.
