I send a daily mail report to the very few users who are super paranoid about missing mail. Each day they get a report that shows all the messages that were rejected, and all the messages that were accepted. the accepted email has the QueueID in the table, and the rejected emails show the IP and helo name that was rejected. It's not very efficient, but it's good enough for the handful of those who want it.
