In javax.mail.smtp.SMTPMessage there is a method setNotifyOptions(int option). What exectly does it do? Does it give feedback on success/failure of mail going thru all the servers and reaching the recepient? Also, Delivery Status Notification has to be supported by sending or receiving server. Finally, is there a way to detect when a recepient actually opened e-mail sent and send a message back to sender?
