The mail system
From: "Mail Delivery System" <MAILER-DAEMON@mail.example.in>
The above mail server host 3 domains i.e example.com, abc.com and xyz.com
But when a message get bounced the above email comes from MAILER-DAEMON@mail.example.com mail id.But I want to change that email id so that if someone get the bounce message and want to know the technical reason then they can contact me at my email id like firstname.lastname@example.org.
Can someone help me to change this default email id of MAILER-DAEMON <MAILER-DAEMON@mail.example.in>
Thank you so much in advance.
