I have users on exchange and outlook 2003. When those users receive email from pop clients that utilize the redirect feature, the email does not show the "by way of" tag. Thus the email looks as though it is being sent from the original sender, instead of by way of the redirector. When I look at the same email inside of Outlook express, I see the by way of tag. Also, when I load the pop client onto my outlook 2003 client, I see the by way of tag. So what setting inside of exchange prevents the "by way of" tag from showing when a user receives a re-directed email? I hear that this may be a function of how Exchange 2003 deals with X- headers. Can anyone elaborate on that.
