I am trying to implement the sending of the notification of the recipient reading the letters. On the Internet, nasperfil such headers:
X-Confirm-Reading-To: <your_mail_addr> и Disposition-Notification-To: <your_mail_addr> But in the standard event CEvent::Send I cannot find how to add these headers.
$headers .= "X-Confirm-Reading-To: $xconf\r\n"; $headers .= "Disposition-Notification-To: $notif\r\n"; Can you please tell me how to do this?
