This is a static main.cf parameter like myhostname, not a dynamic table lookup result like DNSBL response maps. I don't understand how one would make this configurable depending on client input. FYI the time window for Postfix 2.8 changes is closing really soon. If there remains controversy on how this feature should work then it should not be included with the Postfix 2.8 stable release.
