Congratulations. Was the FAQ at <http://wiki.list.org/x/G4CE> helpful?

A custom handler can be enabled for only a single list and should therefore be acceptable to the host. See the FAQ at <http://wiki.list.org/x/l4A9> for information about custom handlers. The place in the pipeline for this particular handler is between Tagger and CalcRecips. The handler itself can be quite simple: ------------------------------------------------------ from Mailman.Errors import RejectMessage NOTICE = """Some nice text for the rejection message. """ def process(mlist, msg, msgdata): if not mlist.topics_enabled: return if not msgdata.get('topichits'): raise RejectMessage(NOTICE) ------------------------------------------------------ -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
