Virtualization discussions

Rik van Riel was indeed kind enough to allow me to use its page (psbl-latest) for a month, for my experiences and measurements against spam. In the past year I have dedicated indeed much man-power investigating alternate techniques to fight spam. By using his page, I was able to collect a bunch of rats in real-time -- and with some dedicated tools I was able to isolate some useful patterns and behaviours.
One of the major work in this investigations resulted in a rather simple idea of connecting back to the sender of the message. There is a fallback: most legitimate senders (like gmail/google, yahoo, or others) have dedicated servers for outgoing emails, thus not letting connections back. This can be supersed by using a convenient white-listing system (a huge reference is listed at: spamlinks.net -- I am testing currently dnswl).

Systems are not perfect (just look briefly to the spam-cannibal as an aperitiv -- or in french -- apéritif)...
