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.

Just curious, but don't e-mail clients ask you whether you want to send the acknowledgement or not? I know Thunderbird asks.

Oh, I see.
The mail you are trying to deliver to me has a "Disposition Notification To" header line in it. This is a common trick used by spammers to prospect for valid mailboxes, because its purpose is to send the message sender an acknowledgement as soon as the message is opened by the recipient, whether the recipient wants to tell you that they've looked at your message or not.
I don't allow mail wanting those acknowledgement messages because I believe they are a privacy violation, so yours is getting rejected.
Delete that line from your email header and you'll get through just fine.
