I don't know about the MTA side, but since this is an announce list, on the Mailman side just moderate everyone and post using an Approved: header. See the FAQ at <http://wiki.list.org/x/XIA9>. The Approved: header contains either the list admin or list moderator password and can also be the first line of the first text/plain part of the message, however in the latter case, if the message is multipart/alternative, removal of the Approved line from the fancy text part is on a best effort basis and is not absolutely guaranteed, so the true header is preferred. Also see the FAQ at <http://wiki.list.org/x/3YA9> for more suggestions about announcement lists. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
