Enable Postfix Service

An XCCDF Rule

Description

The Postfix mail transfer agent is used for local mail delivery within the system. The default configuration only listens for connections to the default SMTP port (port 25) on the loopback interface (127.0.0.1). It is recommended to leave this service enabled for local mail delivery. The postfix service can be enabled with the following command:

$ sudo systemctl enable postfix.service

Rationale

Local mail delivery is essential to some system maintenance and notification tasks.
