Commenti

Per aggiungere un destinatario BCC a un messaggio di posta elettronica, creare un MailAddress oggetto per l'indirizzo del destinatario e quindi aggiungerlo all'insieme restituito dalla Bcc proprietà .

Quando i destinatari visualizzano un messaggio di posta elettronica, gli Bcc indirizzi in genere non vengono visualizzati.
