// Add a primary TO recipient
loo_Email.AddTo("Elizabeth","elizabeth@example.com")

// Add a CC recipient.
loo_Email.AddCC("Jerry","jerry@example.com")

// Add 2 BCC recipients.
loo_Email.AddBcc("Mira","mira@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.
Write-Debug loo_Email.GetMime()

// 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.

if li_Success <> 1 then

end if

Write-Debug "Mail Sent!"

// Examine the SMTP session log.
Write-Debug loo_Mailman.SmtpSessionLog
