I am sending emails using Mandrill and I want to set the Message-ID myself. I see now an ID like this:
Message-Id: <30152892.20150311183809.55008b919f0c49.69649774@mail132-29.atl131.mandrillapp.com>
What I am trying to do is to find out why Gmail does not group messages sent from Mandrill into conversations. Maybe this has to do with the Message-ID and In-Reply-To headers.
I am using the Mandrill Node API and the sendTemplate function has an option to set headers. But this is not working because Mandrill apparently overwrites my ID.
Yes, you can set your own, but you will want to be sure that it follows the appropriate format for a message id. We won't override your id as long as it appears to be valid, but if it's not formatted correctly, we'll overwrite it.
