I don't get read reciepts. I'm pretty sure I have all the correct options
checked. My delivery reciepts come through without a problem.
Thankfully you don't get to control anyone else's computer. Would you
want us to control your computer? If so, enable Remote Desktop and tell
us the username and password so we can do whatever we feel like with
your computer. If the recipient doesn't want to send you a receipt then
that is THEIR choice for their property. You can ask them to enable
prompting or automatic sending of read receipts but if they have disable
them then you are no likely to convince them otherwise. If you want
something back from to let you know that they got your message then put
something in your message asking for that feedback.
