When I look into the log, first the smtpd receives the message from my mail client. Then the email is queued. And then the smtp initiates a TLS layer to send it to the smtpd on the same machine. For my understanding this cannot be correct. The smtpd at first should hand it to mailman and not relay it to itself. Is that correct?
That is not correct. Postfix should receive the initial connect and smtp for the list and then transport_maps should tell it to relay the message via lmtp to the configured lmtp_host and lmtp_port (127.0.0.1:8024 per your previously posted mailman.cfg). You have also posted that Postfix main.cf contains
transport_maps = hash:/var/lib/mailman3/data/postfix_lmtp
What is the content of that file? In particular does it contain
mylists@lists.yyy.com lmtp:[127.0.0.1]:8024
and is the timestamp of /var/lib/mailman3/data/postfix_lmtp.db >= that of /var/lib/mailman3/data/postfix_lmtp, and have you restarted/reloaded Postfix since updating main.cf? And, is Mailman core running and listening on port 8024?
