I remembered reading something like it in Ben Forta's book (CFMX7 Web Application Construction Kit) and I went back and searched. This is what I found:
" ...illustrates one of Internet Explorer 6's policies. Unlike most other browsers, it thinks the file extension-and the format of the actual content itself-is more important than the specified content type. The content type considered only if the file extension doesn't have an associated program, or when there is no file extension. To get consistent behavior with IE, add a content-disposition header to the page request, using a <cfheader> tag, such as the following. The <cfheader> tag is the way ColdFusion enables you to send custom HTTP headers back to the browser, along with the content your template generates. You would add this line right before the <cfcontent> line in Listing 33.3: <cfheader name="Content-Disposition" value="filename=films">" So, I guess you can use Content-Disposition tag somewhere? I am not exactly sure though..Just a thought.

It only happens with IE, though - Firefox correctly figures out the mime type. But, if you open an excel file with Microsoft Excel, and then try to upload it via your web page and IE, you'll discover that it thinks it's an application/octet-stream.
