title: Bouncing a specific email addresses incoming mail
body: <p>I have a need to "bounce" email from a specific email address.  Meaning, when this person emails me I would like them to receive the MAILER_DAEMON message saying that the email address is no longer valid or some other "official looking" message that would make them believe that the email address (mine) is no longer valid.</p>
  
  <p>Is it possible?  I have Gmail but I am also a programmer so I would not be afraid to get my hands dirty with some kind of "server" that takes forwarded emails and then re-routes them or anything creative like that.</p>
  
  <p>Any suggestions?</p>
