Thanks James. This is all very cool. A blacklist (zen.spamhaus.org), a whitelist (list.dnswl.org), and a "greylist". 2.11 looks to be a fantastic release for easily-configured anti-spam measures. I'm just not getting spam anymore and I don't think I'm rejecting legitimate mail either. Thanks to all, Grant
