The above says Postfix successfully piped the mail to the wrapper which
presumably invoked the 'join' script to queue the mail in the
'commands' queue.

Step 1) is CommandRunner running or is the message still sitting in
qfiles/commands ?

The message got delivered to the correct address according to Postfix.

Messages with precedence 'bulk', 'junk' or 'list' are discarded, but
the discard is logged in Mailman's vette log with a message like

 Precedence: xxx message discarded by: testing-request at example.com

If you have an autoresponder set for requests to this list, the message
will be autoresponded to per the autoresponder settings and logged in
the vette log as "replied and discard".

Also look for messages in Mailman's error (and other) logs with
timestamp within a few seconds of Jan  7 21:05:35.
