I tried to edit my previous comment to add the following lines, but was unable to do so. Hence this additional comment:

Lately Thunderbird became extremely slow. I couldn't do anything properly. Typing a few words into a new mail took minutes, trying to move a mail into a folder was trying my patience. I finally disabled mailclassifier, and suddenly everything worked fine again. Thunderbird was quick and smooth again. There still needs quite a bit to be done on this to work meaningfully. With hits less than 5%, and such an impact on Thunderbird's performance, it can't be good.
I admit that I have many (sub)folders. But that can't be the reason for the addon not working properly. I'll remove it and hope for a better version in the future.
