  2. Navigate to the "Serviceability" section and click "Modify".
  3. Verify the provided information and change details if needed.
  4. Click "Test" to verify the provided settings are valid.
  5. Click "OK" to save changes.

If the changes to credentials does not resolve the issue, the administrator for SMTP server should be engaged for further diagnosis, to understand why the server is rejecting the Delphix Engine's attempt to send email alert.
