I know this might be simplistic, and I cannot get it to work, but  the Defaults.py say 
the following:

# These variables controls how headers must be cleansed in order to be
# accepted by your NNTP server.  Some servers like INN reject messages
# containing prohibited headers, or duplicate headers.  The NNTP server may
# reject the message for other reasons, but there's little that can be
# programmatically done about that.  See Mailman/Queue/NewsRunner.py
# First, these headers (case ignored) are removed from the original message.
NNTP_REMOVE_HEADERS = ['nntp-posting-host', 'nntp-posting-date', 'x-
                       'x-complaints-to', 'xref', 'date-received', 'posted',
                       'posting-version', 'relay-version', 'received']

# Next, these headers are left alone, unless there are duplicates in the
# original message.  Any second and subsequent headers are rewritten to the
# second named header (case preserved).
    ('to', 'X-Original-To'),
    ('cc', 'X-Original-Cc'),
    ('content-transfer-encoding', 'X-Original-Content-Transfer-Encoding'),
    ('mime-version', 'X-MIME-Version'),

I was trying to use it to remove X-Mailer and X-Url codes, but as I read it this should 
also remove the original received header - which would be great for announce only 
lists.  Since my IP is in the header my attacks on my personal machine get out of 
hand by pop-up spammers.
