RE: [Exim] Message ID Test, Please Ignore.

>Thank you Microsoft for not setting Message-ID`s in Outlook 2003 =)

I had exactly this problem yesterday (another OLK2k3 user!). In the end, as
I only use Auth SMTP to Exim, I added in this line to my remote_smtp
transport:

remote_smtp:
driver = smtp
headers_add = "${if
def:authenticated_id{MessageID:<${message_id}@$primary_hostname>}}"

You could add a different "if" statement or do away with it all together if
you'd rather.
