| Description | A non-delivery report with a status code of number was generated for recipient recipient (Message-ID id). |
| Event Information | According to Microsoft: Causes : 1)No route is defined for a given address space. For example, an SMTP connector is configured, but this recipient address does not match the address spaces for which it routes mail. 2)Domain Name Server (DNS) returned an authoritative host not found for the domain. 3)The routing group does not have a connector defined ???? mail from one server in the routing group has no way to get to another routing group. Resolution: Verify that this error is not caused by a DNS lookup problem, and then check the address spaces configured on your STMP connectors. If you are delivering Internet mail through an SMTP connector, consider adding an address space of type SMTP with value ????*???? (an asterisk) to one of the SMTP connectors to make routing possible. Verify all routing groups are connected to each other through a routing group connector or another connector. User Action : Verify that this error is not caused by a DNS lookup problem, a non-existent connector, or an incorrect address space. If you are delivering Internet mail through an SMTP connector, consider adding an address space with the value of * to the SMTP connector to make routing possible. |
