Better yet, just block port 25 TO that ip address and spammers will not
even get the chance t send you spam.  They just try for the highest mx
and give up.
          
fake.domain have no ip address
        
  
Watch out for www.rfc-ignorant.org... if 'no ip address', you could 
get your domain blacklisted.
      
You might want to point your bogus MX to a real IP with port 25 closed.
    

Or if you *really* want to be cruel, point it to a box where an SMTP 
tarpit is running...


  

The tarpit would work except for braindead Qmail servers which would 
never try other MX records if the lowest MX responds at all. There's a 
lot of things you can't do with the lowest MX because Qmail isn't RFC 
compatible.
