Ok, so I think we are onto something here. When I send it with a subject line "this is a subject line"

I get this in the subject line on the preview panel of Outlook;

this is with a subject line this is with a subject line

But when I double click on the email to show it in a seperate window, it only shows one, so Outlook is dealing with the duplicate entry and excluding one of the subject line entries in the header.

So the header duplicating the subject line and duplicating the TO: line is the reason why we get two emails. Now, we need to figure out why the header is being compiled this way for some users and not all of them. I tried a theory; logginginto your forums using cookies and without- both methods resulted in dupe emails.

Lionel, do you have...or can you get...header from one of the users that does not get the dupe emails?
