Chilkat2 Python Downloads install with pip pip3 install chilkat2 or download... Python Module for Windows, Linux, Alpine Linux, MacOS, Solaris

import sys
import chilkat2

email = chilkat2.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())

# 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 = chilkat2.MailMan()

mailman.SmtpHost = "smtp.example.com"
mailman.SmtpUsername = "myUsername"
mailman.SmtpPassword = "myPassword"
mailman.SmtpSsl = True
mailman.SmtpPort = 465

success = mailman.SendEmail(email)
if (success != True):
    print(mailman.LastErrorText)
    sys.exit()

success = mailman.CloseSmtpConnection()
if (success != True):
    print("Connection to SMTP server not closed cleanly.")

print("Mail Sent!")

# Examine the SMTP session log.
print(mailman.SmtpSessionLog)

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