How do I add MIME types?

[Jeff Tucker]

Hi,

I have a message with several parts. Among the parts are 
message/delivery-status and text/rfc822-headers.

These parts cannot be viewed with the current IMP. How can I add these MIME 
types, so that they will be viewed inline in a message. I can see some 
types, but not others. Also, I can click on a type message/rfc822 and it 
will open in a new window correctly. Clicking on one of these other types 
does not.

Thanks for any help

Jeff
