What is spamdyke and what does it do?
In a sentence, spamdyke is a drop-in qmail filter for stopping spam at connection-time. “drop-in” means it can be installed without patching or recompiling qmail, without installing or updating libraries, without drastically reconfiguring anything and without having to become a qmail expert. “connection-time” means spamdyke evaluates and rejects spam while the remote server is still delivering it. Other filters and anti-spam solutions focus on classifying spam after qmail has accepted it. The spam still has to go somewhere. Even if it’s filed in a folder, it still occupies disk space, consumes server resources and must be deleted by someone. When spamdyke rejects the incoming spam completely, no one has to deal with it. It’s never on the server at all. For a complete description of spamdyke and all its features, see the README page.
