Would it even help? I don't think so. If it is cached than it would not fail. If it was not cached and there was a temporary DNS outtage at your nameservers, it would bounce. Sending a 500-level permanant bounce is not really a good idea in general... You'd be surprised how often there are temp DNS timeouts.... too man damn people using the Internet these days ;-) However, that said, sending a 400-level sets you up for some bad configurations of other systems which will retry every 5 minutes for 5 days before turning a temp failure into a permanent one... Enough of those could be a real drain. TjL ps -- I have seen more spams in the last week than in the last 3 months.
