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

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

<?php

include("chilkat.php");

$success = false;

$email = new CkEmail();

$email->put_Subject('test');
$email->put_Body('test');
$email->AddTo('Joe','joe@example1.com');
$email->put_From('mary@example2.com');

$mailman = new CkMailMan();

// 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->put_AutoGenMessageId(false);
$email->AddHeaderField('Message-ID','<xyz123@abc>');

$mimeStr = $mailman->renderToMime($email);
print $mimeStr . "\n";

// 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 '--------' . "\n";

// If we auto-generate...
$mailman->put_AutoGenMessageId(true);
$mimeStr = $mailman->renderToMime($email);
print $mimeStr . "\n";

// 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
