Re: Trigger-Words...

Actually, I might not have chosen the correct words for what I wanted... I am looking for sniffer-programs, that analyze e-mail traffic on the Net and filtering out all e-mails potentially interesting for _intelligence services_. For example, I've heard, that if an e-mail contains the words: "assassinate President" (DISCLAIMER: I hope, our President lives a long and happy life, even after his impeachment...:)), it will automatically get filtered and checked out by the Secret Service. Different intelligence agencies might have similar things in place. Where could I get some more information about that?
Many Un*xes (SunOS, Solaris, IRIX, Linux, and probably others) have included their own versions of sniffers, supposedly for network debugging. These are typically called something like "tcpdump", "etherfind", "snoop", etc. You would need to run a sniffer at a "choke point" of an organisation, for example the external router to the Internet, to capture all of the packets to / from that organisation. Putting a sniffer on some arbitrary router out there in cloud-land would probably not be all that productive, since there's no guarantee that all of the IP packets carrying a given TCP connection would take the same route.
