That always happens, and there seems to be no technical way Excuse me -- that always happens? I didn't think so, in a properly set up listserv program with errors going to owner. It *does* happen in some pseudo-listserv programs, I've noticed, and in simple redistribution lists like NIGHT-L. When I post to the Dark Shadows list, I inevitably get back at least one error message with a whole list of addresses that wouldn't accept the posting. It's never happened to me with a proper listserv, though, save where a review shows errors *not* going to owner. >-- Roger Burns [log in to unmask] Mario Rups [log in to unmask]
