Unfortunately i need this, as the postfix is listening on all interfaces and we have the policy to enforce TLS only. Nothing special in the logs:

Is my mailman version maybe too old for this setting?
I'm running GNU Mailman 3.1.1 (Between The Wheels)
Thank you.

No starttls=1 at all :(
Does the above settings work for anyone?
etc/mailman3/mailman.cfg [mta] incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver
smtp_host: localhost smtp_port: 25 smtp_user: smtp_pass: smtp_verify_hostname: false smtp_verify_cert: false smtp_secure_mode: starttls
This should work. What do you see in Mailman's smtp.log if you add
[logging.smtp] level: debugto mailman.cfg.
However, do you really need this. It will only affect delivery from Mailman to Postfix via the loopback interface on the localhost.
