For those on the list who don't follow -private, it was something to the effect of: When a new mail comes in: if from/sender is a subscriber: send it on if from/sender is in whitelist: send it on otherwise: store message for up to 48 hours send challenge to from/sender [ if valid response is received: add from/sender to whitelist send message ] The challenge/response should probably be the same sort of thing you get for subscriptions. This'd allow people who send mail from an address other than what they subscribe from to cope fairly easily, as long as they're posting from a real address (or can add the appropriate headers to point to a real address). Adding a blacklist, or making it "subscriber to any debian.org list", or making the challenge/response require more intelligence, or making a single response work for all the stored messages from that person, would also be options.
