Wietse has reiterated that Postscreen is not designed to do DNS queries (beyond DNSB/WLs). His is the final word on the subject. :) I had a few extra minutes this morning, so I updated Postwhite to optionally allow blacklisting. It's not enabled by default, and I added a warning in the README about the dangers of manual blacklisting. But it's the closest you're going to get to building whitelists and blacklists for Postscreen based on hostnames: https://github.com/stevejenkins/postwhite Good luck! SteveJ
