HI Milosh Unfortunately there is no guarunteed way to be sure someone has read the mail sent. In fact it would in some cases be considered an invasion of privacy ;-)
If's not fundamentally part of email. and read receipt implementations are very much mail server dependent. The most you can say about any sent email (after a number of days) with correctly operating mail servers is that it was delivered to a mail server ;-) And the OP was complaining about not having exceptions raised when non-existent emails where used to send email. Which is definately not something I would expect would happen via the mail api. OP said "I found there are not exceptions thrown even the recipient email addresses don't exist at all. " I am not sure how the mail api could possibly do this, as you may not get the fact that the email bounced because of a non existing email address for days.
