RFC 5322 ● 3.6.3. Destination Address Fields The destination fields of a message consist of three possible fields, each of the same form: the field name, which is either "To", "Cc", or "Bcc", followed by a comma-separated list of one or more addresses (either mailbox or group syntax). to = "To:" address-list CRLF cc = "CC:" address-list CRLF bcc = "BCC:" [address-list / CFWS] CRLF The destination fields specify the recipients of the message. Each destination field may have one or more addresses, and the addresses indicate the intended recipients of the message. The only difference between the three fields is how each is used. |
