I use Alpine which is one of the very few MUAs that take Murray's
advice and ignore MIME headers if the MIME-Version is missing.  It is
a pain in the patoot, since it is invariably wrong.  I ended up using
procmail to add the missing header to mail from known screwups like
the NY Times so I could read it properly.
