The SMTP email server must be configured to enable email and SMS notifications and digests to be sent by the Tenant.


For this activity, users need the predefined Account Owner role or another role with the Configure Email / SMS permission.

Configure an SMTP server

  1. In the Tenant UI, from the top navigation menu bar, click Alert & Respond > Email/ SMS Configuration.
  2. Provide the connection information for the SMTP host and port. 

    • A SaaS Tenant should be preconfigured with the appropriate settings, but verify the settings as the following:

      1. SMTP Host: mx.mail.svc.cluster.local
      2. SMTP Port: 25

      No authentication is needed.

  3. Customize sender address in notifications emails in the From Address field. By default, emails are sent by the root Tenant user. 

    When entering an email address in the From Address field, you have the following options:

  4. If the SMTP host requires authentication, configure the credentials in the Authentication settings. 
  5. If you want to add any text to the beginning of the notification, enter it in the Notification Header Text field.
  6. If you are using SMS, perform one of the following actions:

    • Select Default and choose one of the available carriers from the pulldown menu.
    • Select Custom and enter the phone number receiving the message as <phone number>@<sms gateway>.

      For example, a mobile phone in the United States serviced by AT&T might be:

      A mobile phone in the United Kingdom serviced by Textlocal might be:

      See SMS gateway by country.

  7. Test the configuration by sending an email.
  8. Save the settings.

Troubleshoot Notifications

If you do not receive notifications for health rule violations, it could be because the default SMTP server timeout period is too short.
