Hello, We get bounce-back emails from mailer-daemon when one or more of the recipient addresses are invalid. But, this information is conveyed only in the body of the email and not inside any of the headers.
I'm aware of the bounce daemon along with setting custom bounce messages using a template file but I'm unable to figure out a way to extract the failed recipients and then append that onto the template file as a custom header, say "X-Failed-Recipients". Are they present inside a special variable of some sort that I'm missing out on? Thanks, Abhijith
