Technology behind SpamCheetah spam buster
Gayatri Hitech
Abstract:
Spam control has traditionally been looked upon as a problem
involving probabilistic mathematics, an exercise in linguistics and
even in message digest computation. Of course math alone is not
enough to combat a real life problem. All these approaches have
their merits but it will be nice if we could combine this
intelligence with some lateral thinking.
Spam control is as much a problem in the realm of TCP/IP networking or security as it is with mathematics. The typical tug of war between attackers and hackers in the security world is not very different from the way spammers adapt to spam control techniques. Hence the above mentioned academic approach may not always work. We need to strike the problem at the root. This paper discusses a technique known as OpenBSD greylisting that not only deals with spam effectively but also works with minuscule CPU, memory and consumes the least amount of bandwidth resources. We will see how we can turn away spammers from sending mail to us and even hurt them in the process.
