A spam fighter or anti spam is any tool used to fight spam. Spam is a dreaded affair as it does not serve any useful purpose. Spam is widely used for commercial marketing and for sending fraud mail, phishing mail, phishing campaigns, identity theft, mails with malicious attachments and mails with disguised links. The disguised links lead to websites that host malware or to dangerous phishing websites.
Apart from the malicious nature, the volume of spam that travels over the internet drastically affects bandwidth, computer resources, server performance and hogs the network. It is a public endeavor to develop anti spam tools to block spam at the initial levels, however, as it is easy to create and send spam it has proved to be quite successful for spammers or spam masters.
There are many anti spam filter tools for home and enterprise usage. This article is a comparison of the Comodo Antispam Gateway and SPAMfighter Mail Gateway — two popular tools.
The SPAMfighter is a popular spam filter for Outlook, Thunderbird, Windows Mail and Windows Live Mail. This tool protects multiple email accounts from phishing, identity theft, and other email fraud. It offers a facility to blacklist and block emails and domains and report abuse. It also features automatic whitelist management. For corporate environments, the SPAMfighter Mail Gateway integrates perfectly with existing e-mail infrastructure. It is easy to install, and requires no daily maintenance and can handle up to 200,000 emails per hour. SPAMfighter also supports installation in virtual windows environments to secure the company's e-mail environment.
A Virus Bulletin SPAMfighter review reports a total SC rate of 98.03%. It reports that "SPAMfighter's free product protects the inboxes of many a home-user." Its server product "can run together with Microsoft Exchange or Lotus Domino." "Installation is smooth and the product can be set up easily through a simple web-interface. I was charmed by a graph that showed how many spam emails had been caught and, at $0.04 per email, how much money was thus being saved: while these numbers are nothing but a rough estimate, they show how essential a spam filter is in a business setting.
Unfortunately, the product blocked what it thought was spam a little too eagerly and various legitimate emails were wrongly classified. In particular, newsletters and press releases were blocked and the number of false positives was about twice as high as that of the average product. Hence, despite a decent spam catch rate, the product failed to win an award on its first entry in the test." - Virus Bulletin SPAMfighter review.

Most spam fighters including the SPAMfighter Mail Gateway follow the traditional signature and rules-based method to filter spam. This is effective against "known" type of spam files. This method is effective as far as the definitions are constantly updated and maintained.
However, spammers create new types of spam files or new versions of spam files that do not get detected by traditional spam fighters. A study of reviews would disclose the limitations of signature and rules-based spam fighter solutions. Using such spam fighters and anti apam tools is a futile effort against evolving spam spreading methods.
Effective Spam fighters are those that eliminate email-borne malware threats to your network and data and eliminate bandwidth wastage. They must be able to analyze unknown files without affecting the performance of the user and the system. This is where the Comodo Antispam Gateway scores over the SPAMfighter Mail Gateway and all other spam fighters.
