{4}: The recipient e-mail system does not have enough information to deliver the message. Please see the diagnostic text in the non-delivery report to determine whether this was the Resolver or SMTP component that rejected the message. A Resolver error means that routing configuration could not find a delivery path and an SMTP error means that the DNS records for specific domains cannot be identified. Troubleshooting: For Resolver: Verify that address spaces are configured correctly on send connectors. For SMTP: Verify that the domain name is correct and that domain is functional.
