I have tried to find the answer in the forums but the answer looking not helpful to me. I released that most of answer in forums is about mail_path, yahoo mail account, disable_function etc. After I checked out those and tried to add:

define('FORM_BLOCK_SENDER_EMAIL', 'no-reply@yourdomain.com');
define('EMAIL_ADDRESS_FORGOT_PASSWORD', 'no-reply@yourdomain.com');

I added above two php coding into site.php, but it still does not working at all. One more things to mention that I did not received email from concrete5 when I do a reset password in login page. Can anyone tell me what is the issue for this problem and the solutions?

The logs message is on below:
