I'm trying to find out how to set DSN when using PHPMailer. I know at the SMTP Protocol level, the DSN is specified after RCPT TO, e.g. RCPT TO: NOTIFY=SUCCESS,FAILURE ORCPT=rfc822;recipientemail@gmail.com
Also, I will like to direct the DSN to other than the sender address if that is possible. Appreciate any pointers, thanks.
