Tutorial - How to Receive Emails from Outside domain - Postfix Configuration

My server configuration: Ubuntu 20.04 - 4GB RAM - Cyberpanel with Litespeed free version

Check your main.cf (postfix file)

nano /etc/postfix/main.cf

Add or change

mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
relay_domains = $mydomain
mydestinations = $mydomain, $myhostname, localhost, localhost.localdomain

You should have added more info, some people will have hard time understanding this. :slight_smile:
