Event Id951
DescriptionWhen sending mail to following address <server name>, we have found the connector with target domain <%2> matching destination address exists in DS. However, we have no way of getting there. Possibly, you need to check your topology and add appropriate connectors among Routing Groups
Event Information"According To microsoft:"
This Warning event can indicate a problem with the link state table or with the routing topology. The link state table is used to determine the most appropriate route for a message, based on cost and availability.
If the link state table becomes corrupted, mail flow problems such as delayed mail or non-deliverable mail can occur. For example, a link state table can become corrupted because of such issues as Active Directory replication latency and connectors being created and deleted at the same time.

To resolve this event, try one or more of the following:
1. Verify your routing topology using the WinRoute tool.
2. Verify that all connectors are configured correctly and started. If you have to, create new connectors or re-create deleted connectors.
3. Make sure that link state information is being correctly replicated to all servers in your organization.
