I had a Smart Folder (saved search) in Thunderbird Supernova that collected all my Spam folders. It's clunky, doesn't refresh consistently, etc., but I noticed that JustReportIt doesn't work on these, only on the real folders. That could also be a technical limitation in how Thunderbird implements this feature.
I'm not entirely sure how other mailers implement Smart Folders, though.
