Hello I use the PSFC4 for my Linux mail server. I want to change the setting for SMTP auth so that users on my network don`t have to use username and password for sending mail, just users outside my network. How do I set this up
If you use Postfix, just change the mynetworks value in /etc/postfix/main.cf and restart Postfix. For example, if your network is 192.168.0.0, add 192.168.0.0/24 to mynetworks.
