I figured it out. And it was neither a Mailman nor a Postfix problem.
systemd-journald simply enforced some rate limiting. After removing it (setting RateLimitBurst=0 in /etc/systemd/journald.conf), delivery for all mails can be seen in the logfiles.
Are you saying that the emails actually were sent, but systemd dropped the log messages so you wrongly thought they weren't sent?
That was the case. Only the log messages in syslog were missing.
To be clear: AFAICT everything was working as configured.
