When a message is sent to two recipient addresses, that happen to share the same mailbox, duplicate delivery is often a fact of life. Deduplication is ultimately up to the mailstore and the mail-user-agent. However, in Postfix, you can somewhat reduce the incidence of duplicate deliveries with: http://www.postfix.org/postconf.5.html#enable_original_recipient enable_original_recipient = no Whether this would help you or not is hard to say without logs showing all the log entries for the queue file(s) that were logged by cleanup(8) to have the Message-Id in question. -- Viktor.
