cPanel Track Delivery displays delivery reports for messages handled by the account and can help distinguish successful, deferred, failed, or still-processing deliveries.
- Open cPanel → Email → Track Delivery.
- Filter by the recipient address and run the report.
- Use Show Blocked & Failed to focus on failures.
- Read the Result/response information for rejection, timeout, routing, or connection details.
- For a deferred message, note that the mail server can retry delivery rather than treating the first deferral as a permanent failure.
Track Delivery depends on server configuration and can be unavailable or incomplete when a third-party mail service handles delivery.
