Hi Mark, Hi Stephen, so I updated now my configuration a bit. The logging is now default:

nomail
notifempty
rotate 14
dateext
su mailman mailman
olddir /var/log/mailman/mailman-logs/oldlogs
postrotate
/bin/kill -HUP `cat /opt/mailman/var/master.pid 2>/dev/null` 2>/dev/null ||
true
# Don't run "mailman3 reopen" with SELinux on here in the logrotate
# context, it will be blocked
/opt/mailman/mailman-venv/bin/mailman reopen >/dev/null 2>&1 || true
endscript
}
It is now more like the Fedora one and seems to be better.
Now in the mailman.log I see the HOLD messages and the approved messages. The
smtp.log logs just the incoming Mail, which seems to be fine.
So, here a complete Trace:

Even after changing the smtp_host in mailman.cfg this error appears randomly.
Sadly the mail does not get delivered.

The standard logging levels from lowest to highest are
debug
info
warning
error
critical
Whatever level is set for a log results in all messages of that level or higher
being logged. I.e. if the log's level is debug, all messages for that log of
any level should be logged.
For every shunted message, a message like
`SHUNTING: <file name without the .pck extention>` preceded by the exception
and traceback is logged to error.log with level error. See
https://gitlab.com/mailman/mailman/-/blob/master/src/mailman/core/runner.py?ref_type=heads#L182-L199

As I said before, blindly restarting Mailman is a bad idea. On servers that I
maintain, I always verify that all queues are empty before stopping or
restarting Mailman. If necessary, I'll kill the incoming runner and wait for
the out queue to empty and then stop mailman. If you want to do this daily, you
could automate that., e.g.
```
if queues empty:
restart Mailman
else:
when in queue is empty, sigterm incoming runner
when out queue is empty, stop Mailman
when Mailman stopped, start Mailman ``` The stop/start is needed because a
simple restart at that point won't start the sigtermed incoming runner.
