There are some basic strategies you can employ in order to troubleshoot and solve problems with the
system. However, it is important to remember that Cisco Systems offers Technical Support for complex
issues (see Cisco IronPort Customer Support, page 1-4).
Note Several of the features or commands described in this section will affect, or be affected by routing
precedence. Please see Appendix B, “Assigning Network and IP Addresses” in the Cisco IronPort
AsyncOS for Email Configuration Guide for more information.
Debugging Mail Flow Using Test Messages: Trace
You can use System Administration > Trace page (the equivalent of the trace command in the CLI) to
debug the flow of messages through the system by emulating sending a test message. The Trace page
(and trace CLI command) emulates a message as being accepted by a listener and prints a summary of
features that would have been “triggered” or affected by the current configuration of the system. The test
message is not actually sent. The Trace page (and trace CLI command) can be a powerful
troubleshooting or debugging tool, especially if you have combined many of the advanced features
available on the Cisco IronPort appliance.
