Turning off an appliance

When you turn off an appliance, the process begins immediately. If you have emails in your message queues, those emails remain in the queues. Before you turn off the appliance, first stop the mail flow. As a precaution, you might also want to flush your inbound, outbound, and delivery message queues.
