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

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

LOCAL nSuccess
LOCAL oEmail
LOCAL oMailman
LOCAL cMimeStr

nSuccess := 0

oEmail := CreateObject("Chilkat.Email")

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

oMailman := CreateObject("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:
oMailman:AutoGenMessageId := 0
oEmail:AddHeaderField("Message-ID", "<xyz123@abc>")

cMimeStr := oMailman:RenderToMime(oEmail)
? cMimeStr

//  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...
oMailman:AutoGenMessageId := 1
cMimeStr := oMailman:RenderToMime(oEmail)
? cMimeStr

//  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
