active spam killer for windows (afw) is a challenge/response spam filter system for the windows platform. it builds on the excellent work done by marco paganini on his active spam killer (ask) for linux. in fact, afw includes the latest public release of ask.

as well as adding windows compatibility to ask by wrapping it in a pop3 client/server pair, afw includes a full web interface to the ask mail queue, its filtering lists, user administration, and module options. in addition, afw allows an unlimited number of users, each of whom can define an unlimited number of remote pop3 servers to poll.
