Creating no-reply@domain.com account in Postfix

If you wanted to send emails to users but did not want to receive any replies to the email, you would need to setup a no-reply@domain.com email account. These kind of email ids are useful when sending emails containing forgotten passwords or activation code. Below are the steps for creating such account in Postfix. 1.

(You may require root privileges) > newaliases > postfix reload
