      No-one is interested.

      You have an SMTP-based before-queue content filter that takes
      minutes of time to process a file, causing the Postfix smtpd_proxy_filter
      CLIENT to time out.

      Per the SMTP definition, repeated timeouts will result in
      REPEATED DELIVERY ATTEMPTS.

      It is these MULTIPLE DELIVERY ATTEMPTS that result in multiple
      deliveries.
