First thing is: I turned out what I did wrong and now unsubscribing works. I haven't read carefully manual (sorry) and I created just one form however its needed two. For next people: read carefully manual and in current version you must create:
- action "unsubscribe"
- two forms: "OptOutConfirm" and "UnsubscribeQuery"
Then this feature works.
Second thing regarding mistake in manual sorry Masschoff but I think still there is mistake because in real app there isn't action "Load recipint data". For proof I'm attaching screenshot with all options. Generally I chose "user_get_data" in this place and it works (to be clear).
Moreover unfortunatelly I have another problem yet

. Unsubscribing works but statistic of bounces not. Statistic of send emails yes but bounces not. I've send just 4 emails (one is fake), in /var/log/maillog there is bounce record but unfortunatelly Openemm stil shows bounces=0. Even I updated update.py script from bug fixes section download but still nothing. Can you help me Maschoff what it can be ?
