Email Security through Procmail (the Procmail Sanitizer) provides methods to sanitize email, removing obvious exploit attempts and disabling the channels through which exploits are delivered. Facilities for detecting and blocking Trojan Horse exploits and worms are also provided.

VK Mail has three main components: an email daemon that acts as a proxy to any standard mail server, an email parser, and a Web mailer. All these together allow users to send email by simply typing an email address in a standard graphical Web browser, and allow better anti-spam control for email recipients. The goal of this project is not to develop an anti-spam email filter that simply deletes the junk messages after they are already delivered to the user. Instead, it rejects emails from spammers.
skill sends signals to processes given any combination of user names, ttys, commands, and pids. snice changes the priority of processes (given the same). They are similar to kill(1) and renice(8), but the commandline is order-independent. There are also verbose, search, and interactive modes of operation.
Xnetintf is an X Windows application that manages network interfaces. The current interface state is depicted through a series of bitmaps, and a mouse click in the window initiates a state transition. Xnetintf uses a per-interface configuration file to supply commands that check and toggle state, as well as a program to run after the state change completes. A command line interface is also supported.
