I'm sure this is quite easy but I just can't figure it out at present so please give me a hint:

How do you prevent a spam message from hitting "USER_IN_WHITELIST", because the spammer faked the sender address in such a way that it looks like a local address (which is in fact white-listed in local.cf) ?

use whitelist_from_rcvd, or don't whitelist your local addresses at all.

whitelist_from_rcvd requires two parameters, the second of which should be an RDNS that matches your inside hosts, but not your mailserver.

ie:

whitelist_from_rcvd [EMAIL PROTECTED] lanhosts.evi-inc.com

(where lanhosts.evi-inc.com would be a subdomain containing my inside machines that appears in the Received: headers)
