A "Select Recipients" window will open.  Hold your "control key" (Ctrl) on your keyboard down and click on all the names in your address book that you want to send the email to.  If you are sending the email to "everyone" in your address book, click on the first name in your list, hold your "shift key" down then click on the last name in the list to select them all.


Once you've selected the list of recipients, click the Bcc: button in the middle of the window pane and all the names will appear in the window on the right.  Click OK.

You'll notice all the people you selected from the list in your Address Book, are now listed in the Bcc: window of your Message Window.  Compose your EMail, click Send.

Oh happy days!! You've protected the EMail addresses of your friends/family from spam harvesters.

BONUS TUTORIAL (Using the Reply versus the Reply All button)

When someone sends you an EMail with cc's (carbon copies) or bcc's (blind carbon copies) to a hundred other people, DON'T make the mistake of replying to the person who sent you the EMail by clicking the Reply All button.  Not only will the 'sender' get your EMail, but so will every single other person that received the original EMail.  Instead, be sure to click the Reply button so that ONLY the sender of the EMail gets your reply.

Thanks for helping to fight SPAM!
