Nikita, I have done what you are saying MANY MANY times, but it is a huge manual process that only puts a scratch in getting results. Believe me I have looked in the log file for how many times an address connects, then how many times it fails from those connections and then lookup what country they are from until finally adding them to a blacklist per say. Imagine with a 6GB monthly maillog how long this process can take, it's just too time consuming.
