How to allow LinkedIn but block LinkedIn Mail application

The following Applipedia screenshot shows the subdivision of LinkedIn Mail from LinkedIn Base, which is the general Application.

If you allow the LinkedIn Base Rule, then succeed it with a new rule of blocking the LinkedIn Mail application (followed by a Commit); this will allow LinkedIn but block the Mail portion of the application.

Note:  If using a wild card in your URL filtering profile to match any URL for LinkedIn, the correct syntax is  *.linkedin.com, not *linkedin.com.
