Explanation: The MTA cannot route a message to the domain it is addressed to because available indirect links create a circular reference.
Possible Cause: Links between domains in your GroupWise system are not set up correctly.
Action: Check, and if necessary, adjust the indirect links between domains in your GroupWise system. See "Editing a Domain Link" in "Domains" in the GroupWise 6.5 Administration Guide.
