Perhaps what's needed is a filter on messages coming into Vger that removes duplicates before they hit Majordomo's resend. The filter could look for duplicate message IDs or even better, a header added by resend or Zmailer to outbound messages (Sender:, X-Loop:, etc.). Pretty easy to do with Procmail/formail or some small modifications to resend. Majordomo's taboo regexps could do the trick, but they'd result in a bounce to the list owner.
