28.8 Starting Postfix on a Fedora 31 System
Once the /etc/postfix/main.cf file is configured with the correct settings it is now time to start up postfix. This can be achieved from the command-line as follows:
# systemctl start postfix
To configure postfix to start automatically at system startup, run the following command:
# systemctl enable postfix
The postfix process should now start up. The best way to verify that everything is working is to check your mail log. This is typically in the /var/log/maillog file and should now contain an entry resembling the following output:
Mar 25 11:21:48 demo-server postfix/postfix-script[5377]: starting the Postfix mail system
Mar 25 11:21:48 demo-server postfix/master[5379]: daemon started -- version 3.3.1, configuration /etc/postfix
As long as no error messages have been logged, you have successfully installed and started postfix and are ready to test the postfix configuration.
