You COULD require that all your mail have the "Content-Type: text/plain; 
charset=us-ascii" or "Content-Type: text/plain; charset=iso-8859-1", but 
this won't always work.  For starters, this is not going to work for mail 
with attachments, since its top level MIME content type is going to be 
multipart/mixed.  Furthermore, you'll have plenty of mail without any MIME 
headers whatsoever, but containing valid us-ascii text. 

Courier has an option to bounce all mail that does not have proper MIME 
encoding.  That's a far better solution - in nearly every case the improper 
character coding is due to missing or invalid MIME headers.
