LOCAL loEmail
LOCAL lnSuccess
LOCAL loMailman
LOCAL lcMimeStr

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Email')
loEmail = CreateObject('Chilkat.Email')

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.MailMan')
loMailman = 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:
loMailman.AutoGenMessageId = 0
loEmail.AddHeaderField("Message-ID","<xyz123@abc>")

lcMimeStr = loMailman.RenderToMime(loEmail)
? lcMimeStr

* 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...
loMailman.AutoGenMessageId = 1
lcMimeStr = loMailman.RenderToMime(loEmail)
? lcMimeStr

* 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
