procmailrc

Hi, 
   are there some ways to let .procmailrc use as conditions datas from
elsewhere?

Example: I want procmail to archive in pippo all e-mails in which the
         "From:" is one of those names contained in an ascii list pluto,
         on which we have no control?

Pluto-list:
 aaa(_at_)somewhere(_dot_)com
 bbb(_at_)somewhere(_dot_)else(_dot_)com
 ccc(_at_)anywhere(_dot_)it

thanks
