I need a information about PHPMailer about replying my own mails. I need send a empty mail(subject, body), and when the first mail sent second mail need sending with replying first mail. That's possible ?
I tried but never can repyling my own mails.
Yes, but PHPMailer won't do this for you. You will need to do it by getting and setting appropriate headers, in particular the Message-ID header that identifies each message, and the In-Reply-To and References headers which are used to track whether something is a reply. Probably the best way to see these working is to simulate it using your regular email client - Outlook, Gmail, Apple Mail – all of which will set those headers correctly.
