MS's lack of adherence to the protocol.
To bring this closer to Mimedefang, let's look at MS's adherence to the smtp protocol. Outlook, under some circumstance, understands a 550 permanent error to mean try again forever. At the present time we have a user whose PC tries 6,000 times a day to send a message to our smtp server without smtp auth, and it gets 550'd every time, and it has been doing this for over a year. The user says no error is shown on screen, and the user cannot find the message in an outgoing queue. Since the PC is on a changing dynamic connection from an ISP, and since the user needs to send other mail, we have not filtered by IP or sender address. We currently have a few other cases of this, but they don't send as many times daily. Maybe it means the people don't have Outlook running all day, or maybe it means something else. In our case the smtp auth test is done by sendmail, but, look, it *could* be implemented in Mimedefang, and then this would be on topic!
