2. Browse to "Configuration" and click "Access Logging". Check the "Enable Access Logging" option and click "Apply".
3. Click Policy >> Visual Policy Manager >> Launch.
4. For each Web Access Layer, right-click the "Track" column for each rule and select "Set". Click "New," and select "Email".
5. Select "Custom Recipients" and click "Configure Custom Recipients Lists".
6. Click "New," provide a name for the list, and enter the ISSO and ISSM email addresses in the "List Members" field.
