OK,
I now force ipv4 by adding inet_protocols = ipv4 and postfix forwards mail
correctly now. However the two test mails were stuck in the queue. Even a
forceful flush did not convince postfix to lookup the smarthost again.
I deleted the two mails from the queue.
Anyway, I still think this is wrong, and I really cannot explain the
behavior. The lookup worked pre systemd-resolved. And actually I still
cannot explain why postfix stopped at the failed AAAA lookup. And I cannot
explain why postfix did not pick them up after I forced ipv4 only.
