China-NN (China News Network) is a moderated list. Only the "editors" difined in the list header can post to the list. But we find that on some sytems (such as CMS), when people forwarding a mail, the FROM field of the mail remains unchanged. One subscriber forwarded a mail posted by editor back to the list, the FROM field is still "cnd-editor", so the listserv mistook it for the posting from editor and distributed it to the whole list again. My question is: Is there such a function in listserv that dectect the original sender instead of 'from' field and prevent those forwarded mail being redistributed? M.
