Messages sent to and from Microsoft Exchange Server can be tracked to determine the cause of mail-related problems. You can:
When message tracking is enabled, each component handling mail records its activities in a log maintained by the system attendant on each server. The log becomes a trace of the processing of each message as each component receives, processes, and delivers it to the next component. The tracking logs are stored in \Exchsrvr\Tracking.Log.
For more information on message tracking, see Microsoft Exchange Server Maintenance and Troubleshooting.
When a message is passed from the Microsoft Exchange Server computer to the Internet, multiple events are logged in the tracking log. Each log records one day's activities on the server. The tracking log can be displayed by using the Microsoft Exchange Server Message Tracking Center.
The following table defines the Internet Mail Service activity in the tracking logs.
|SMTP transfer out||The message is received by the Internet Mail Service from the Microsoft Exchange Server information store.|
|The message is received by the Internet Mail Service from the Internet.|
|SMTP transfer in||The message is received by the Microsoft Exchange Server information store from the Internet Mail Service.|
|SMTP message rerouted||The message was received by the Internet Mail Service and rerouted to another domain.|
For information on rerouting, see "Routing Properties" earlier in this chapter.
