How to Add Bcc Recipients in Mac OS X Mail

In the Bcc: header field, you can add recipients who will get a blind carbon copy. The other recipients of your message will not know that it also got delivered to Bcc recipients.

If you start composing a new message in Mac OS X Mail, there is no Bcc: field. By default, Mac OS X Mail only shows the To: and Cc: address fields.
