How to auto reply with read-receipt

[Raymond]

Hello

I am always feeling offended when someone send you an email and ask for
read-receipt and you have to respond with a read receipt, is it possible to
create an add-on to send an auto receipt back?

Thank you.

I know there is a tracking option in Outlook to always send back responds,
but it doesn't have the option to turn this on to only certain sender.

I just tested the tracking option, actually it is not what I am looking for:
it does send back read receipt, but only after I read it. However, what I am
looking for is: I want the receipt be automatically sent back to the sender,
no matter if I read it or not. I think someone is using this "request read
receipt" function to track if you are staring your screen and respond quickly.
