Yet there is nothing worse than an inbox full of spam; i.e., information crafted to be delivered to a large number of recipients against their wishes. In this paper, we present a numerous anti-spam methods and solutions that have been proposed and deployed, but they are not effective because most mail servers rely on blacklists and rules engine leaving a big part on the user to identify the spam, while others rely on filters that might carry high false positive rate. KEYWORDS E-mail, Spam, anti-spam, mail server, filter. 1. INTRODUCTION The internet community has grown and spread widely in a way that not only is it connecting every one of its users into one virtual globe, but also affecting them. Given that the internet is still in an ongoing evolution, states that this virtual community of people (users) is growing and with this growth comes great value, a value of people connected all together in a certain period of time all of the time, now imagine what this could bring forward as a target regarding marketing, advertisement, at the same time it could also hurt such users when such marketing and advertisement are misused, therefore affecting the resource structure of this globe along with its users. Consider a table whose resource structure are its four wooden legs which is able to hold a capacity of 50 kg, now bring a load of 70 kg and you will notice that the table would be crippled and broken, now apply that on the internet community whose resource structure are its communication which is able to hold up to a certain level of bandwidth, if we abuse that level and raise it up the internet community will be crippled and get affected by itself and its users thus costing the whole community a burden which starts from spam. Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not choose to receive it, and is also regarded as the electronic equivalent of junk mail. Most spam is commercial advertising and is generally e-mail advertising for some product sent to a mailing list or newsgroup. This is done by the abuse of electronic messaging systems including most broadcast media, digital delivery systems to send unsolicited bulk messages at random. While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup
