Similarly, I didn't really expect that posting here would turn up a magic solution, but I can't really think of what else to check. I know that the mail is leaving Google, and I know that it's not arriving into Postfix, but I don't know where it's ending up. The server is on Amazon AWS, so there shouldn't be anything in front Postfix that could be filtering the message.
