I'll second that. We've taken to 4XX (tempfail) on unknown client during the day when our mail loads are high. this has greatly reduced the amount of SPAM we handle. I can't leave it on all day because too many clueless net/mail admins sending legitimate mail (20-30% i estimate) also don't have valid rDNS.
