reifman writes: Filtered is a new open source IMAP mail filtering application which provides a platform for training, routing and experimenting with your email. Filtered can learn from the contents of your existing folders, respond to drag and drop events and can be fully trained through a web interface. But, it's also a platform which can be used by programmers to create new features for email such as Quiet Hours which shuts off your inbox on certain days and times, Whitelisting which challenges new senders to authenticate themselves as human and a Secure folder which deletes messages from your NSA-inhabited Gmail account and stores an encrypted version on your server. Filtered is written in PHP in the Yii Framework and is available now on Github. There's a detailed installation guide for trying out the app with a cloud-based Linux server.
