I launched an application which sends you an email a few months back (https://emailprivacytester.com/ https://emailprivacytester.com/). It alerts you in real time when the email leaves my server and hits your MX or is rejected by your MX, keeping you informed on the page of any permanent/temporary rejection messages or the accept message from the remote MX. I figured it would be useful for people to know if the message was still in my queue attempting to be delivered or if it had been rejected/accepted by their MX.
