create a dns record  (MX) for yahoo.com pointing to 127.0.0.1 or any other ip address...or an invalid ip address...not only did you direct emails to your own server, you can actually have a catch all address in virtusertable to catch all emails address to yahoo.com into one account.
But then...that would be tantamount to eavesdropping or wiretapping -- I would suggest just direct it to /dev/null or an invalid ip address so it bounces back.
