Monterey: delivery receipt with Apple Mail

• Hi Everyone!

I am trying to set up the delivery email receipt from Apple Mail; I used this for setting it on:

Quit Mail

• Open Terminal (/Applications/Utilities/)

• Enter the following text (make sure to keep all quotes exactly as is!)

defaults write com.apple.mail UserHeaders '{"Disposition-Notification-To"="your@address";}'

(In place of "your@address", enter your own email address)

So, it partially worked out, the person who received my email did receive my email with the notification of email receipt, although this command seemed worked out as Reading Receipt, whilst I am looking for the Delivery Receipt (the same one that WIndows users can do through Outlook).

Any help?

Many Thanks in Advance

PS: the Unix command above has been taken from another post provided by Timothy Simmons, who thankfully wrote those lines for another similar question.

Read receipts are consider the bane of email— and practically useless

I would not waste time on this in the macOS.

You can switch to WIndows or Outlook if this is mission critical to your workflow.

What a great opportunity for scammers/phishers to collect and sell valid email addresses. If you sent me an email that automatically sent back a confirmation it would be the last email I ever saw from you.

Much of the Outlook functionality in that area is based on an Exchange server processing the information. It is controlled by Microsoft, so it can do many things actual email servers do not provide.
