Anti-Spam Server App

I need an app that will run as a service on a Windows 2000 OS. It needs to operate like a mail server. This app needs to function exactly like the Spam Arrest service [login to view URL] but we want it to operate from our server. We don't care if you make it as an app that operates identical to theirs or if it adds these features to our existing mail server which is MDaemon [login to view URL] We just desperately need to filter the quantity of Spam that comes into our server. You can see a demo of how the spam arrest works at [login to view URL] The first time a person sends an email to a user on the server, they are sent an email telling them that they need to click a link and that they will only have to do this once. Once they click the link, that email address is added to a list of emails that are allowed to come into that persons mail box. The idea is that a spammer won't be clicking the link, so only humans get through. The link takes them to a web page that tells them that they have been added to the approved list.
