Check the aliases file (/etc/aliases) as that is where the
              Majordomo lists email aliases are kept.
              Technically, the mail aliases for majordomo lists point to
              wrapper scripts that trigger certain actions for a particular
              list, like subscribing for the geton.XXX@cat.org.au alias, or
              sending to everybody on the list for the
              XXX-outgoing@cat.org.au alias, etc.
              If you are looking for a owners of newer Mailman lists, go to
              /usr/lib/mailman and start there, or goto
              http://lists.cat.org.au
