* Another topic: A friend had once DeltaChat installed, keys had been exchanged, and therefore secure communication has been established. Great! However, this friend has uninstalled the App and now I'm facing the problem that my DeltaCHat still sends out encrypted emails to him. How to force DeltaChat to try to update his status (maybe by re-exchanging keys and after a specific period set his status to 'no encryption').
Keep on working on this great tool
