Filtering internal mail and forwarding to another domain

Our company has an account on Google Apps mail. We have set up a postfix server on our LAN that gets the mail from the Google mail domain and routes it to the required user. Since the postfix server is the final destination of the mail thus any mail from one user on our domain (say xyz.com) is to another user on xyz.com is relayed internally only. I would like the mail to be relayed internally and to be forwarded to an alias of the google domain. Also note that mails not meant for xyz.com should be relayed outwards without passing through the filter. Is all this possible? If it is then how is it feasible?
