Microsoft Exchange Server provides tracking functions that your gateway can use to record auditing and accounting information. The gateway is responsible for providing the tracking functions with data about each message that passes it. Microsoft Exchange Server specifies the information to be passed.
Gateways use the functions listed in the following table to handle message tracking.
| Function | Action | When Called |
|---|---|---|
| HrTrackInitLog | Initializes the gateway event tracking session. | As gateway starts. |
| HrTrackWriteLog | Logs a tracking event. | For each message. |
| HrTrackUninitLog | Uninitializes the gateway tracking session. | As gateway stops. |
