E-mail addresses added to your address book are automatically considered safe and messages from them will go directly to your inbox, not to even be considered as spam. Therefore, add addresses to this safe list that are friends, family and websites whose mail you wish to receive. Enter only addresses that you know and want to receive mail from. For example, be sure to add the e-mail addresses of online newsletters when you sign up for them so that they won't go to the junk mail folder.
This safe list is called a white list just as the names added to your black list are those you wish to have blocked. Use the white list to keep your e-mail inbox spam-free.
