Here are the corresponding logfile entries from mailmanweb.log:

and from mail.log:
Oct 14 12:06:26 domain postfix/smtpd[722764]: NOQUEUE: reject: RCPT from

lists.domain.tld is the domain for Mailman3. I don't know why it's trying
to send email from root@.
I think the mail.log entry is for the DSN for the failure. The issue is
the HELO/EHLO command. Try the following in your venv
```
(venv) ...:~$ python
Python 3...
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.getfqdn()
```
If that returns `localhost`, that's the issue. I think you can fix it by
putting a fully qualified domain name in /etc/hostname.
