In some cases, it is very important to have a certified proof that a mail has been read. The Read Notification is not very relevant to address this requirement. Indeed in a lot of cases, a message may have been read by the receiver, although no notification has been sent. For example : the POP3 or IMAP4 protocols allow to retrieve message from the Message Store, so that the sender receives the delivery notification when the message is delivered by the MTA, but it could take time to receive the read notification due to the fact that the message is retrieved on the receiver PC. The Receiver could read the message in disconnect mode. Nowadays, a lot of e-Mail clients are based on an interface displaying the list of messages and the message content displayed in another window. In this case, the receiver could read the message but without opening it, so the read notification is not sent.
