To complete this lab: - Install, start, and enable the Postfix service, if needed. - Configure the service with the following information: - `myhostname` is `node1.mylabserver.com` - `mydomain` is `mylabserver.com` - Install `mailx` and send a test email to the cloud_user account to test your configuration. Good luck!
