Hello Mark,

finally it works! The clue was that the 
was missing in mm_cfg.py. After that the mail was delivered locally, and 
mailman could send it to the list members. The /usr/lib/mailman/bin/postfix-to-
mailman.py line in master.cf is commented out, it indeed works fine following 
your hints.

Thank you again a lot for your patience! You will agree there are a lot of 
documents on the net leading in the wrong direction.
