It means that the words 'From:' or 'Sender:' or 'Reply-To:' and the
name of the list were found on the same line in that message. Usually
happens when someone replies back to the list quoting the headers of
the message. Just tell that user to exclude the mail headers from
the message (s)he is replying to..  -turgut
