Thank you for your explanations. Now I think I've got it.

So I analyzed the POST data produced when I attach an Excel document.

On the one computer who doesn't attach the right MIME type, the Browser 
sendes in the POST data this "Content-Type: application/octet-stream" 
for the file.

On a similar computer, also WinXP with Firefox, the Browser adds the 
correct content-type: Content-Type: application/vnd.ms-excel


Now what's the difference between the two systems that they handle this 
different? What can I change on the system who does the MIME thing wrong?


Thanks, Yves
