The thing is that after a lot of config tweaking also the "senders = :" seems to work. I needed to go around errors_to -router option by different way, and that probably that fixed also my bounce routing and this senders-stuff.
So I cannot reproduce my error mentioned earlier, and it might have been a logic-error in my configuration.
