My windows C++ app has a HTML form in which I am generating a mailto link. Once the user clicks on it, goes to his/her email client and sends the message, is there a way for me to know in the app if the mailto succeeded?
My gut feeling on the answer is no. In any case checking with the smart folks here.
No. There is no way for you to know if an email reached its recipient - unless you get a mail (or other communication) back from the recipient saying they got it.
