    // 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.
    printf("%s\n",CkEmail_getMime(email));

    // 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>
    // CKX-Bounce-Address: 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.

    // -- Note: You may notice the "CKX-Bounce-Address" header.  This is a header that appears in the MIME
    // -- but is automatically removed when a Chilkat method to send email is called.
    // -- Chilkat automatically removes all headers beginning with "CKX-" when sending email.

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