About Test Tools & Mail Flow Troubleshooting
From time to time, you’ll need to ensure that the message service is running as
desired. The System Tests section of the Administration Console includes several
programs for testing and troubleshooting the delivery of email.
If you have a mail delivery emergency (no incoming mail), see “Troubleshoot
Incoming Email Delivery” on page 292.
