Source: GroupWise Message Transfer Agent.
Explanation: The MTA is unable to route a message because it does not recognize the domain to which it is addressed.
Possible Cause: The sender manually typed in an invalid address.
Action: Have the user select the recipient from the Address Book, then resend the message.
Possible Cause: During a reconfiguration of your system, a user has addressed a message to a location that either no longer exists or does not exist yet, because the reconfiguration information has not yet replicated throughout the GroupWise system.
Action: Wait until replication is complete. The MTA will retry the operation.
Possible Cause: The message has been damaged so that the destination information is no longer readable.
Action: Remove the damaged message from the MTA input queue so it can process subsequent messages. Have the user resend the message.
