1. Log in to your "webmail" account. Click on the gear icon, pictured, to access your settings.
2. Once your settings are pulled up, click on the "mail" link, located underneath the section "Your app settings"
3. After you have selected "mail", expand the mail section and click on "accounts". Then select "block or allow".
