It looks like the user doesnt exist so yes 99% sure it is a bounce. Just for
some reason this list is really bad at cluttering the mailq.
It's a bit of a puzzle. Postfix should be trying to deliver the mail to
Mailman's LMTP runner. It doesn't really matter what the content is.
Mailman's LMTP runner should either accept or reject the recipient, but
it appears that neither has happened and Postfix is just waiting.
Look for messages similar to these
```

```
in Mailman's smtp.log. It's tricky because the process that writes them
doesn't get notified when the log rotates so current messages may be in
an older generation of the log.
Note the connection lost messages are normal.
In any case, see if when you have a hung message in Postfix you get the
first few of those but not all. It will be interesting to see where they
stop if that's the case. These are written by aiosmtpd which actually
handles the Mailman side of this connection. What version do you have?

When my mailq get hundreds to thousands stacked up, all email slows to a crawl. Is your DNS setup correctly? Can you confirm the NLx.shaw is able or not able to be resolved?
