You don't want to do that. The approach I've found that works least badly is to do stringent spam filtering (spamassassin with a threshold of about 4), forward the stuff that passes, and put the rest in a local mailbox that is polled by POP3 from the Google account. That's easy to set up, and he'll get all of his mail eventually. If Google puts stuff in the spam folder that he wants, not your problem.
