use chilkat();

$email = chilkat::CkEmail->new();

$email->put_Subject("Test email subject");
$email->put_Body("Test email body");

$email->put_From('Test <joe@example.com>');

# Add a primary TO recipient
$email->AddTo("Elizabeth",'elizabeth@example.com');

# Add a CC recipient.
$email->AddCC("Jerry",'jerry@example.com');

# 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.
print $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>
# 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.

$mailman = chilkat::CkMailMan->new();

$mailman->put_SmtpHost("smtp.example.com");
$mailman->put_SmtpUsername("myUsername");
$mailman->put_SmtpPassword("myPassword");

$mailman->put_SmtpPort(465);

$success = $mailman->SendEmail($email);
if ($success != 1) {
    print $mailman->lastErrorText() . "\r\n";
    exit;
}

$success = $mailman->CloseSmtpConnection();
if ($success != 1) {
    print "Connection to SMTP server not closed cleanly." . "\r\n";
}

print "Mail Sent!" . "\r\n";

# Examine the SMTP session log.
print $mailman->smtpSessionLog() . "\r\n";

# Here you can see the session log and the BCC email addresses included in the "RCPT TO" commands.
