Mail released/deleted before confirmation

[Mike Usmar]

Hello, I have come across a problem (or it may just be part of tmda), where any mail released or deleted before the sender sends a confirmation request back, they sender gets back and "unknown user" bounce message.   In detail, I tested this with 2 of my email addresses, one was using tmda (user1), the other wasn't (user2). User2 sends an email to user1, and since user2 is not on any lists for user1, a confirmation request is bounced back to user2. However user2 logs off their computer after sending the original message, therefore not getting the confirmation request. User1 then happens to be checking their pending email (they are curious), and they come across an email from user2. They read the email, and then delete, or decide to release it to their mailbox. Then a while later, user2 checks their mail again, and they come across the original confirmation request, relise they have to reply, and send a reply. But because user1 has already released/deleted it, user2 receives a bounce back from the mailer-daemon (postfix or whatever is running) saying that the user1 does not exist.   Here are the exact email that user2 was getting back:   =============================================== This is the Postfix program at host *******************.
