Rated 3 out of 5 stars

This is a great idea. However, it doesn't seem to work on my computer. I am running Thunderbird 2.0.0.21 in Ubuntu.
It seems to slow down Thunderbird quite a bit, but maybe that's because of the close to 1.000 emails in my inbox? After restarting Thunderbird, all the classifications of my emails are gone and I have to start the classification over. It doesn't seem to classify new messages; it only works when I tell it to classify the entire inbox.

This review is for a previous version of the add-on (1.0).
