Entering the fully qualified domain name

Administrator Help | Forcepoint Email Security | Version 8.5.x

The Fully Qualified Domain Name (FQDN) section of the System Settings page is used to define the FQDN. SMTP protocol requires the use of FQDNs for message transfer. If you completed the First-Time Configuration Wizard, the FQDN you entered there appears on this page as the default entry.

If you did not complete the wizard, enter the appliance fully qualified domain name in the field Fully Qualified Domain Name (format is appliancehostname.parentdomain.com).


	Important This setting is important for proper email security system operation. You must replace the default fully qualified domain name entry with the correct appliance name. An incorrect fully qualified domain name may cause disruptions in email traffic flow.
