Hi Petr, I have been thinking about this as well. Question to everyone: What kind of conditioning do you think could be applied to Vipul's Razor, in order to avoid such poisoning? A simple example is the following condition: "If there are more than four agents reporting a mail as spam, and if they are located in different ASs, then the mail is considered as such". What other options can you think of? --C PS: Thanks to Steve and Robert for providing insight and a link to http://spamassasin.org (which I was not aware of). Petr M. Swedock wrote:
Is't possible to use this to 'poison' the catalogue: that is to say, how easy is it to create a denial-of-service for legitimate mail?
Peace,
Petr
