Do I have to configure email to use PolicyPage?
No. You can define Groups, Members, Web sites, Profiles, and Rules and evaluate Web Sites without configuring email. However, if you want to use PolicyPage to send email notifications to web site owners, you will need to configure email. You also need to configure email if you want to allow potential new users of your PolicyPage installation to self-register. See documentation on creating new users. See documentation on configuring email.
