[New-bugs-announce] [issue42859] smtplib: recipe for certifying message delivery

New submission from Dmitry Goldenberg <dgoldenberg123 at gmail.com>:
Is there a reliable way to certify (ensure, track) the delivery of an email message when using smtplib?
Disposition-Notification-To message header which enables the e-mail reader of the recipient to send confirmation e-mail when the recipient opens the message for the first time. That e-mail reader program must support this functionality.
Return-Receipt-To message header which enables the e-mail server of the recipient to send confirmation e-mail when the original e-mail gets received by that server. However, most newer e-mail servers do not support Return-Receipt-To header.
Are these message headers at all reliable?
The request is to enhance the documentation to provide an example of how to track a message delivery. Conversely, if it's plain not possible, the request is to state that explicitly in the docs.
