Policyd v2 (codenamed "cluebringer") is a multi-platform policy server for popular MTAs. This policy daemon is designed mostly for large scale mail hosting environments. The main goal is to implement as many spam combating and email compliance features as possible while at the same time maintaining portability, stability, and performance. Its features include detailed policy and group specification, access control, helo/ehlo checks (helo randomization prevention and RFC compliance), SPF checks, Greylisting, Quotas, and Amavisd-new integration.
Gmagick is a PHP extension to create, modify, and obtain meta-information of images using the GraphicsMagick API. GraphicsMagick prides itself as the swiss army knife of image processing. It works with over 88 major formats including DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF. Gmagick consists of a main Gmagick class, a GmagickDraw class that is in effect a drawing wand, and a GmagickPixel class of which instances represent a single pixel of an image (color, opacity).
The primary aim of the Gtk+2 panel project is to provide a panel that reuses whatever is available (if it is not overkill) in the obvious way, such as subclassing GtkWidget instead of implementing applets, or by using a GtkBuilder file instead of defining a new format to customize the panel. This approach gives some additional advantages for free: you can use common tools in uncommon ways. Above all, you can use Glade to design your own panel. All the dependencies apart from GTK+ are (and hopefully will be) optional.
SMRadius is a high performance pre-forked RADIUS AAA server. It features a highly configurable backend engine supporting flexible data specifications. Its primary goal is to provide an extremely flexible authentication platform which may serve a large number of industries, including ISPs and WiSPs.
Graylog2 is an syslog implementation that stores logs in MongoDB. Messages are accepted via TCP or UDP. A Web interface allows you to view the log messages. It also implements GELF, the Graylog Extended Log Format, which is a simple JSON string that allows you to send long and structured syslog messages, which is very useful for customized application log monitoring.
