sa-exim-stats generates spam/mail statistics from an sa-exim logfile. sa-exim is a patch for Exim which integrates SpamAssassin into Exim. The script's output includes: total spam messages, total clean messages, spam percentage, top n spam/clean/overal recipients. The script is designed so that it doesn't have to scan the entire logfile everytime it is run (status can be saved to a file or in a MySQL database). It can create and update a RRD database, and some basic PHP pages to display the graphs are included.
Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
