# moderate owner distribution-alias
#
# ensure message gets redistributed to a distribution list alias yet
# error messages come back to the list owner.  This requires invoking
# the mailer again.
#
# A mailing list is then set-up by adding aliases as follows: (articles are
# mailed to example, administrivia to example-request, error messages go back
# to example-owner, and the list of recipients is example-people).
#
# example: "|/local/lib/mail/bin/moderate example-owner example-people"
# example-request: lamy
# example-owner: lamy
# example-people: ":include:/local/share/mail/lists/example"
#
# note that your sendmail may not want the " around the :include, but
# that zmailer does in the name of RFC-822...
