how do I block read receipts and delivery receipts

Well, two different computers both using the Mac Mail program with two different domain e-mail addresses all responded to the read receipt and the delivery receipt from both an HTML e-mail and a plaintext e-mail. Any suggestions on what else may be going on?

Here is the receipt from my e-mail:

The original message was sent using Outlook Web Access from Safari on my Mac using my work e-mail account. The message was sent to my wife's accounts, which she received using her Mac. I also sent to my own Mac to also test. When it went to my own Mac, it was on the same Mac that sent the e-mail via Outlook Web Access.

The read receipt and delivery receipt were delivered to my work e-mail account whcih I could see using Outlook Web Access.

The short answer to your question was that you were correct. :-)

Interesting.

I received a delivery receipt even though there is no mail program open on my mac (or my iPhone or anywhere else) that has yet received the message.

Okay, you have focused me better on describing what is going on. The subject of all my messages included Read Receipt or RR because that is what I was looking for. But when I sent the message, I also included a delivery receipt. Looking back, it is only delivery receipts that I get. It does not look like I ever got an actual Read Receipt. It was always a Delivery Receipt.

And since my Mail program didn't even need to be open, the delivery receipt is happening somewhere outisde my computer.
