I have no impact caused by filter rules or addons detected. Yesterday I detected a new processing mode: "After closing TB the rewsidual moved mails disappear from the Smartphone E-Maibox" after few seconds. It looks that TB sends a synch with the now empty Mail In-Box to the smartphone during the closing cycle.
I have no idea why the new processing mode is now in place. Maybe I have changed something when I tested
possible Addon and Filter problem sources.
