Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Email')
$email = new COM("Chilkat.Email");

$email->Subject = 'Test email subject';
$email->Body = 'Test email body';

$email->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() . "\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.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.MailMan')
$mailman = new COM("Chilkat.MailMan");

$mailman->SmtpHost = 'smtp.example.com';
$mailman->SmtpUsername = 'myUsername';
$mailman->SmtpPassword = 'myPassword';
$mailman->SmtpSsl = 1;
$mailman->SmtpPort = 465;

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

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

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

// Examine the SMTP session log.
print $mailman->SmtpSessionLog . "\n";

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