HOWTO install p3scan
	P3SCAN

Configuration b: P3scan on client itself

Characteristics:
- clientprogram and p3scan are running on the same host
- redirection (with iptables) on the same machine: only local.

P : pop3 server G : gateway/router S : switch/hub C : client p3scan and redirection on client magenta: original,redirected and p3scan traffic in one red: p3scan connection/traffic

Note:
The pop3server does not have to be on the Internet: can be anywhere. Most important here is that the gateway which intercepts the pop3traffic and does the scanning is physical between the client and the pop3server.

TODO:
- p3scan has to be installed on the client (and iptables too)
- p3scan has to listen to the local address
- configuartion of iptables: not so simple: add two rules, one to intercept pop3 traffic coming from mailprograms like Kmail, THinderbird and Evolution, but let through pop3 connections coming from p3scan
