61.247.246.43 is not in fact yahoo.com.  It lacks reverse DNS but it
seems to be part of bhartibroadband.com in India.  Maybe it's a
Yahoo user sending mail with a PC client instead of using Yahoo's
web page.  You're trying to use SPF perhaps?

Anyway if that error message is in your Mimedefang filter you can
rewrite it to act differently.  Mimedefang does what it is told.
