Rated 5 out of 5 stars
thank you for the update.
unfortunately I have to wait for the official release of the add-on by Thunderbird developers, because I can't download it from the page https://github.com (mailing-list-filter/content/ ..... I didn't find any .xpi files there)
Hmm, it was pretty fast now, they apparently got some more volunteers for addon reviews. Enjoy!
