SMTPSenderRefused - howto enable STARTTLS for local mail drop
Dear users,
how can we configure mailman3, to use STARTTLS when dropping mails to local postfix for final delivery?
Mailman seems to not support this. Even the web-interface complains:
SMTPSenderRefused at /accounts/login/(530, b'5.7.0 Must issue a STARTTLS command first', 'postorius@lists.mydomain.tld')Request Method: POST Request URL: https://mm3.mydomain.tld/mailman3/accounts/login/ Django Version: 2.2.12 Exception Type: SMTPSenderRefused Exception Value: (530, b'5.7.0 Must issue a STARTTLS command first', 'postorius@lists.mydomain.tld')Exception Location: /usr/lib/python3.8/smtplib.py in sendmail, line 880 Python Executable: /usr/bin/uwsgi-core Python Version: 3.8.10 Python Path: ['.', '',
Thank you.

Set smtp_secure_mode: starttls in the mta section of mailman.cfg.

No matter what i try, mailman still only connects without STARTTLS:
/etc/mailman3/mailman.cfg [mta] incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver

Earlier you wrote:

This looks like Django errors, not Postorius (Mailman). So this is something Django is doing, not Mailman (including Postorius). I'm not sure why Django is sending email (somebody made a password reset request seems likely, but I'm not that familiar with Django authn stuff). Anyway, if it's internal to Django, it would not consult Mailman's configs. This recent StackOverflow seems relevant:

Hi Steve,
thank you for your time. Thats it :) Works now. I had to set it in /etc/mailman3/mailman-web.py
After first logon, django tries to send a mail to confirm email address.
Nov 10 08:44:56 mal02 postfix/qmgr[2893767]: 9255C5E0BE2: from=postorius@lists.mydomain.tld, size=920, nrcpt=1 (queue active) Nov 10 08:44:56 mal02 postfix/smtpd[879486]: disconnect from localhost[::1] ehlo=2 *starttls=1* mail=1 rcpt=1 data=1 quit=1 commands=7
This now works with STARTTLS. Hoooray :)

Need to bring this up again. Django now sends with STARTTLS, but mailman itself, does still only drop mails in cleartext. Dec 6 11:47:33 al01 postfix/lmtp[7598]: A6422600510: to=remote-party@remote, relay=127.0.0.1[127.0.0.1]:8024, delay=0.01, delays=0.01/0/0/0.01, dsn=2.0.0, status=sent (250 Ok) Dec 6 11:47:33 al01 postfix/qmgr[29156]: A6422600510: removed Dec 6 11:47:35 al01 postfix/smtpd[8092]: disconnect from localhost[::1] ehlo=1 mail=2 rcpt=2 data=2 commands=7
No starttls=1 at all :(
Does the above settings work for anyone?

This should work. What do you see in Mailman's smtp.log if you add
[logging.smtp]
level: debug
to mailman.cfg.
However, do you really need this. It will only affect delivery from Mailman to Postfix via the loopback interface on the localhost.

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:

Thank you.

There should be a Dec 07 08:14:14 2021 (12303) Starttls entry here.

Yes, it's too old. STARTTLS support was added in Mailman 3.3.0
