Auto-Generate or Explicitly Specify the Message-ID Email Header

Demonstrates how to auto-generate or explicitly specify the Message-ID header field. Chilkat2-Python

import chilkat2

success = False

email = chilkat2.Email()

email.Subject = "test"
email.Body = "test"
email.AddTo("Joe","joe@example1.com")
email.From = "mary@example2.com"

mailman = chilkat2.MailMan()

# When the mailman sends email, it renders the email to be sent,
# and then sends the rendered MIME.

# Instead of actually sending the email, this example will render
# to MIME so we can see what would be sent..

# We can explicitly set the Message-ID like this:
mailman.AutoGenMessageId = False
email.AddHeaderField("Message-ID","<xyz123@abc>")

mimeStr = mailman.RenderToMime(email)
print(mimeStr)

# This is what we get:

# MIME-Version: 1.0
# Date: Mon, 20 Jul 2020 17:20:09 -0500
# Message-ID: <xyz123@abc>
# Content-Type: text/plain; charset=us-ascii; format=flowed
# Content-Transfer-Encoding: 7bit
# X-Priority: 3 (Normal)
# Subject: test
# To: Joe <joe@example1.com>
# From: mary@example2.com
# 
# test

print("--------")

# If we auto-generate...
mailman.AutoGenMessageId = True
mimeStr = mailman.RenderToMime(email)
print(mimeStr)

# We get this:

# MIME-Version: 1.0
# Date: Mon, 20 Jul 2020 17:21:20 -0500
# Message-ID: <04EDE096BBFE484967F6398A973B0FCF6EA09A44@CHILKATSLICE>
# Content-Type: text/plain; charset=us-ascii; format=flowed
# Content-Transfer-Encoding: 7bit
# X-Priority: 3 (Normal)
# Subject: test
# To: Joe <joe@example1.com>
# From: mary@example2.com
# 
# test
