@fdroidorg What trackers are in these packages? The descriptions do not indicate which trackers, if any, are included.

K-9 6.x has NO trackers. But MZLA made it clear during the Thunderbird/K-9 8 beta process they have no commitment to maintaining that status quo. In fact, some of their people were downright hostile to the idea of an app that didn't send tracking data to them, even when it was pointed out the way it was being handled violated the EU's GDPR.
