BCC property will internally scan headers and search for
'BCC' header, and return its information to you.
Before it does that, it will decode the value if UNICODE
was used so that you get printable expression in your
applications. If there is more than one recipient, it
should be divided by comma character.
Blind carbon copy recipients means that each recipients
only sees himself as the recipient of the message, and does
not know the other recipients (as when CC field is used).
