Sending, replying, forwarding email
Bcc: Blind carbon copy

All Internet email programs provide three different fields for supplying recipient email addresses when creating new mail, replying, and forwarding mail. At least one (any) of these fields must be populated with a properly formatted email address in order for mail to be sent (includes replies and forwards).

• To: Primary recipient(s) list. All recipients in the To field are visible to all recipients of the message.
• Cc: (Carbon copy) Secondary recipient(s) list. All recipients in the Cc field are visible to all recipients of the message.
• Bcc: (Blind carbon copy) List of recipients that are NOT visible to other recipients of the message.

More technical information can be found in the following sections of RFC 5322: Internet Message Format.

Some mail programs have the Bcc field enabled already; others do not. For most of the mail programs below, you will not need to repeate the steps every time you want to use the Bcc field.
