Postfix configuration

Our postfix server regularly receives emails with the following basic form: Using regular expressions we would like to forward/redirect emails to a list of users. Regular expression matching needs to be done on all 3 fields (to, from and subject) so that if any 1 field does not match then the email will not be forwarded/redirected. This solution needs to be implemented within postfix – we will take advice on whether we need to install any additional software (such as procmail) to achieve a solution. The solution needs to be scalable, so we can have unique user lists for each regex set of From,To and Subject fields.
