    //  Add 2 BCC recipients.
    email.AddBcc("Mira","mira@example.com");
    email.AddBcc("Alexander","alex@example.com");

    //  BCC recipients will not be present in the MIME of the email that is sent.
    //  However, the BCC recipients are included in the recipients provided to the SMTP server
    //  during the SMTP protocol conversation. This will be shown below.

    //  First, let's look at the MIME.
    std::cout << email.getMime() << "\r\n";

    //  MIME-Version: 1.0
    //  Date: Sat, 30 Oct 2021 07:58:32 -0500
    //  Message-ID: <183D5F51163BE4374B494D2ED067DE2783CC761B@SLICE>
    //  Content-Type: text/plain; charset=us-ascii; format=flowed
    //  Content-Transfer-Encoding: 7bit
    //  X-Priority: 3 (Normal)
    //  Subject: Test email subject
    //  From: Test <joe@example.com>
    //  To: Elizabeth <elizabeth@example.com>
    //  Cc: Jerry <jerry@example.com>
    //  
    //  Test email body

    //  Notice that the BCC recipients do not appear in the MIME.  But don't worry, they are still present within the email object.
    //  The difference between CC and BCC recipients is that CC recipients appear in the MIME.  Thus, the recipient of the email
    //  can see the CC recipients, but cannot see and is unaware of the BCC recipients.

    //  ----------------------------------------------------------------------------------------------
    //  Let's send the above email and examine the SMTP session log to show that the BCC recipients also receive the email.
