We are having a number of customers complaining that the formatting of the original mail message content is being adjusted on mail forward.  What we are seeing is the text of the original messages are being wrapped in SPAN tags with the default font for new messages being applied. This is out side of what gmail, Hotmail, windows mail and most other tested mail clients do. I have a number of clients that are forwarding marketing e-mails where the formatting should not be changed. They are more than frustrated.  How can we address this issue?
