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

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

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

$email = New-Object Chilkat.Email

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

$mailman = New-Object Chilkat.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)
$($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

$("--------")

# If we auto-generate...
$mailman.AutoGenMessageId = $true
$mimeStr = $mailman.RenderToMime($email)
$($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
