# All this does is massage the headers so they look like what news
# software expects.  To:, Cc: and Resent-*: headers are masked.
# Reply-To: is turned into references, which is questionable (could
# just as well be dropped.
#
# The From: line is rewritten to use the "address (comments)" form
# instead of "phrase <route>" form our mailer uses.  Also, addresses
# with no "@domainname" are assumed to originate locally, and so are
# given a domain.
#
# The Sender: field below reflects the address of the person who
# maintains our mailing lists.  The Approved: field is in a special
# form, so that we can do bidirectional gatewaying.  Any message
# in a newsgroup that bears this stamp will not be fed into the
# matching mailing list.
