There is a remote possibility that a hash: table rebuild race with incoming mail could cause a message to be returned as undeliverable. Normally postfix logs all returned mail, but your logging seems incomplete. Please see http://www.postfix.org/DATABASE_README.html#safe_db Note: while this potential problem is documented and real, speculation that this is what happened to your missing message is an unproven wild guess. Additional evidence might be found in your log in the form of a bounce message delivered by your postfix to the sender of the mail in question, or evidence of returned mail might be found on the originating server. -- Noel Jones
