The SMTP service can be configured to automatically stop and start on reboot. This is done by adding symlinks to the mail transfer agent's initialization scripts in the appropriate system directories.
For example, on Red Hat Linux, add S* and K* symlinks to the sendmail or postfix initialization script (located by default in
/opt/pmx/postfix/etc/init.d respectively). These symlinks must link from the appropriate
/etc/rc.d/rc[0-6].d/* directories. The correct location of these symlinks is dependent on the run level that has been selected for your operating system.
Starting the SMTP service after PureMessage at boot-up, and stopping the SMTP service before PureMessage at shut-down is recommended to prevent unnecessary tempfails while the server is rebooting.
For information about stopping and starting services on other platforms and configuring initialization scripts, refer to your operating system's documentation. For instructions on configuring PureMessage to automatically stop and start during reboots, see starting PureMessage automatically on reboot.
