Challenge-response anti-spam methodologies are also often referred to as greylisting, e.g. in this document: http://linuxmafia.com/faq/Mail/challenge-response.html I also thought this was what you meant; challenge-response grey-listing predates the milter method of grey-listing, if I'm not mistaken. However my arguments hold true here, as well. Milter grey-listing is an incomplete solution, and once again could potentially interfere with mass-distribution mailings that I actually *want*, or possibly even mail from people I know who maintain their own mail server, but aren't so good at configuring it. You usually need to use it in conjunction with something like spamassassin for best results. All the same problems I mentioned before apply. Your kind of grey-listing is what I would use if I were setting up spam filtering on a corporate mail server today, in conjunction with spamassassin or similar; but it's still not as good as what I do. But what I do doesn't scale well to multiple users, and requires that I run my own server. Which, works for me, but doesn't particularly work in a corporate environment. -- Derek D.
