a) Create mail with a unique Message-ID (or other) header before giving it to Postfix. b) Configure Postfix to generate unique message ID headers for you. http://www.postfix.org/postconf.5.html#enable_long_queue_ids c) Use a Milter or SMTP-based content filter to add a header after giving the message to Postfix. http://www.postfix.org/CONTENT_INSPECTION_README.html Wietse
