They must not return codes that lack text after the third digit (e.g., they should return 5.7.1 Rejected rather than just 5.7.1).\n- Access Tables and Content Checks: Audit custom access tables, header_checks, body_checks, and transport_maps (specifically error transports) to confirm that any manually defined rejection messages or status codes include descriptive text following the numeric code."
