You can edit the system email settings, including configuring the SMTP server settings and VMware Cloud Director notification settings.
VMware Cloud Director requires an SMTP server to send user notifications and system alert emails to system users.
VMware Cloud Director sends system alert emails when it has important information to report. For example, VMware Cloud Director sends an alert when a datastore is running out of space. You can configure VMware Cloud Director to send email alerts to all system administrators or to a specified list of email addresses.
