Example to Add Several BCC Email Recipients

See more Email Object Examples

Demonstrates how to call AddBCC once per email recipient. Chilkat2 Perl

use strict;
use warnings;
use Chilkat2;

my $email = Chilkat2::Email->new;

$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>
# 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.

my $mailman = Chilkat2::MailMan->new;

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

my $success = $mailman->SendEmail($email);
if (!$success) {

    print "Connection to SMTP server not closed cleanly.\n";
}

print "Mail Sent!\n";

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