In today's fast-paced world, emails have become perhaps the most widely used mode of communication. Whether its personal or professional, the person you may wish to contact is always just an email away. Instant, and extremely user friendly, emails have increasingly become an integral part of day-to-day communication. However, unwanted spam is a major hassle that email lovers face every hour. Every time we access our mail box, it is flooded with mails which are completely unsolicited. These spam mails are not only annoying, they can even contain dangerous viruses. To counter the spam, email spam filters are extensively used. Email is broadly categorized into Web-based email like Yahoo, Hotmail and Rediffmail, and client-based email like Outlook Express or Eudora. Both types of emails have different setups and require unique spam filters to effectively block spam. Web based emails usually have free spam filters. These filters may be content-based or work on the basis of a pre-provided blacklist of spammers. Spam filters for client-based email are generally of three types: server side filters, standalone filters, and integrated filters. Server-side filters check the spam at the ISP location, whereas stand-alone filters reside on the PC and wash out spam from the email as the user receives it. Integrated filter/clients eliminate spam, in a manner similar to web-based anti-spam systems. These types of filters require every new sender to verify their address. Stand-alone filters are by far the most extensively used spam filters for client-based mails, as they not only offer the best spam removal rates, but also do not require the user to alter or switch the email clients. Empower your PC with any of the innumerable spam filters now available to enjoy a junk-free email experience. |
