Delivery notices of any sort were pretty much deprecated a long time ago. If you ever had 20 or 30 UUCP hops sending DSN messages on each message that was passed through you can understand why. > I'm not sure DSNs are ever appropriate as "proof" of anything. They're not - and they won't stand up in court. That's been tried. All any expert has to say is that by definition, email is _by definition_ an unreliable mechanism and it's all over. > No DSN tells you anything > about the disposition of the message, by design. Indeed, and even mail client notices such as "was opened" or "was deleted, unread" don't mean much due to the triviality of forgery. As always, if it really has to get through, use certified mail and if you want to confirm delivery, use a phone call.
