The mailbox provider has no way of knowing that you sent the mail. If it was authenticated as coming from you this wouldn't be an issue. One mail was sent to *you*. It's OK for you to have access to it. The other mail was sent to someone *not you*. There's no a priori reason you should have access to the content of the message.
