And that was bad advice. It is needed. See below.

That is as it should be except for the ultimate 'unknown user' which I
don't fully understand.

It's not.

This is as it should be.

The above are the aliases that cause mail to the local addresses
'discuss' and 'discuss-*' to be appropriately piped to Mailman.

These are virtual mappings that map virtual addresses like
discuss(-*)@cpddomain.org.au to local addresses discuss(-*). This part
is working correctly per the part of the log message that says
"to=<discuss at main-domain.au>, orig_to=<discuss at cpddomain.org.au>,",
however the part that says "relay=local, ... status=bounced (unknown
user: "discuss")" is saying that for some reason, the alias

discuss:             "|/usr/lib/mailman/mail/mailman post discuss"

is not being processed by Postfix even though the message is being
handled by the 'local' transport.

What are the ownership and permissions on /etc/mailman/aliases.db. Is
the time stamp of this as recent as that on /etc/mailman/aliases? Are
there any Postfix log entries related to /etc/mailman/aliases?
