Question about porcmail

I am wondering if procmail can handle the mail that got the domain name right
but invalid user without returning it to the sender?
eg.    no-one(_at_)my(_dot_)email(_dot_)address where my.email.address is right 
but
       no-one is not a user on my.email.address
       usually the mail is returning to the sender, how about I don't
       want to return it, but store in a folder.

thanx

Can procmail do it?
