procmail with option ?

Hello, I'm Alex from Spain

I want to filter my mails with procmail, but I have a problem :

   I want to accept mails from one of senders that I have in a local 
file (address_book).
   I think that procmailrc must be similar to :

    0:
    * ? aux=`formail -X "From:" | cut -d" " -f2` &&  grep $aux address_book
    mybox

Are there other way to do the same more easy?

Thanks 

Sorry about my bad english
