How to obtain email address with window authentication

I am designing a web application using the ASP.net MVC framework. I would like to use Windows Authentication and do Role Checks using the Role Manager SQLRoleProvider.

How can I determine the email address of the current logged on user? Is this even possible?

The application will be deployed in a multi-domain intranet, if that matters (which I assume it does).

Thanks for any help!
