Queue behavior
Take a look at http://technet.microsoft.com/en-us/library/bb232161.aspx to see, what actions will cause re-routing. Configuration changes with re-routing: The connector is deleted. The queue is resubmitted. The connector is disabled. The queue is resubmitted. The connector is modified to remove the local server from the source server list. The queue is resubmitted. The connector is changed to a DNS connector. The queue is resubmitted. The smart host list for the connector is modified. The updated smart hosts list is automatically detected and used during the message delivery phase. Any DNS MX resolution failure occurs. The queue is retried until messages expire. The connector is disabled. The queue is resubmitted. The SMTP server is offline or the destination isn't running an SMTP server. The queue is retried until messages expire. Regards, Chris
