That's from the post log. There should also be a message in the
smtp-failure log of form 'delivery to %(recipient)s failed with code
%(failcode)d: %(failmsg)s' giving more specific information about the
failed recipient and reason.

The sender and message-id in the log message you quote indicate that
this is a Mailman generated message, not a post, possibly a notice of
a held post or a response to a message to listname-request, etc.

Most likely the original messages are spam and Mailman is sending some
response to the sender of the spam and your MTA is rejecting the
response recipient.
