Email clients ask if you want to send a return receipt if they are requested by the sender yes. But I can understand Brian's position. There is also such a thing as a delivery receipt, which is not at the discretion of the email client or recipient, the email server will send a mail returning that the message was delivered, no matter what your other client-side settings are.
