What will happen in the scenario that user x...@example.org does not exist (on either the Postfix or Domino server). If the Postfix machine sends mail addressed to this user on to the Domino server which then bounces it, you will generate backscatter. This is bad. Figure out a way to accept mail only for actual users and reject everything else at RCPT TO. -- Sahil Tandon <sa...@tandon.net>
