Example to Add Several BCC Email Recipients

See more Email Object Examples

Demonstrates how to call AddBCC once per email recipient. Ruby

require 'chilkat'

success = false

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() + "\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.

mailman = Chilkat::CkMailMan.new()

mailman.put_SmtpHost("smtp.example.com")
mailman.put_SmtpUsername("myUsername")
mailman.put_SmtpPassword("myPassword")
mailman.put_SmtpSsl(true)
mailman.put_SmtpPort(465)

success = mailman.SendEmail(email)
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

success = mailman.CloseSmtpConnection()
if (success != true)
    print "Connection to SMTP server not closed cleanly." + "\n";
end

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.
