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.
