Displaying HTML email as HTML in the page


We have just started using RT for internal products requests and the
only real issue we have had so far is that when viewing a ticket, while
there is a link to the HTML attachment, actually clicking on it results
in the HTML source being displayed. We actually need to be able to see
the actual HTML page itself (in a new window would be fine - currently
we have to save the .html to disc and then open it using Firefox). Is
there any way to configure this behaviour?
