Question : wrong Email should be reach particular mail box insted it bounce back

I need help to configure incoming mails to reach to one particular folders :

senario is :  i am having      fabrikam.com domain

i am having more than200 users.  if some send an email  to my user it would be deliver to respective inbox, but if some one type wrong email id like    [email protected] insted he type  [email protected]   this email should not be bounce and it should be come to one  mailbox.
not only this any email ID if some one type wrong.. it should not be bounce back..it should be reach to some mailbox to check whether it is genuine or spam.

this was implemented some companies...may i know how to do this,

Regards, Raju
