To configure how the Notification e-mails are sent you, click on the "Notification" menu item under the "Settings" menu item. Notification e-mails are delivered by default via the built-in "NovaBACKUP Alerts" SMTP service.
You can also configure CMon to send Notifications using a "Custom SMTP" server. Make sure to fill in all of the details that are prompted for. Once the prompts are filled in click the " Test Email Settings " button to verify all of the settings are correct prior to saving, otherwise your Notification e-mails will fail.
