Hi-de-hi, Just a thought: The majordomo has the list of ppl subscribed to this mailing list. Why not set up a filter that only accepts mails from a subscribed address.
Hm, as I'm typing this, I already know the answer: it's pretty simple to fake a FROM field in a mail, so filtering on that won't do any good. Eric -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html
