Although there are many forms of spam (involving blogs, instant messaging or even mobile phones), the most frequent form remains, to this date, e-mail spamming. The reason why this tendency has soared in recent years is the fact that economically, it is a very cheap form of advertising. Numerous companies resort to this method, because all they have to do is handle a number of mailing lists, and it is quite difficult to hold them responsible as well as to implement anti spam techniques.
Implicitly, the receiving public has to cope with efficiency loss and time loss. Even e-mail service providers have had to raise the capacity level in order to deal with the extra-unwanted mail. Its costs are huge ? the U.S. alone spent millions of dollars last year on lost productivity, and although cases are rare, there have been people who ended up in the court of justice over spamming issues.
Without an anti spam technique at work, any PC with a connection to the Internet is extremely vulnerable. Concisely, the purpose of anti spam software is to keep e-mail messages that you never required away from your inbox, by previously detecting them. After you install your anti spam program, it immediately filters all the e-mails that come your way.
This happens through a number of criteria for sorting out the emails. These criteria form the basis for the functioning of the spam filter. They comprise certain words in the subject or the content of the e-mail as well as certain types of files that come attached to the message, including special images. In addition, a spam filter allows you to see the address of the person, company or organization that sent the message in the first place. You can do this without actually opening the message, which is an essential feature ? a large percentage of global spam messages contain viruses and other files that may be severely damaging for a computer.
Moreover, there is always the option of inserting a certain number of e-mail addresses into your spam filter ? addresses belonging to people that you know and trust, who are utterly unlikely to send spam messages. In this manner, you are completely sure you will continue to receive messages from these people. The common attached to this process takes the form of your personal whitelist. In addition, there is the concept of blacklist as part of a spam filter. This includes a series of registered addresses known to send spam messages on a regular basis. The process is quite simple ? if a message sent to your e-mail address comes from one of those addresses, the filter immediately rejects it.
Spam senders have gone to great lengths to refine sending methods, including everything from address harvesting to the message itself. In spite of all this, the point of a spam filter is to discern, as efficiently as possible, between wanted and unwanted e-mails, thus allowing you to receive legitimate messages without interference. This is essential as part of the security tools that protect you and your computer, so choosing your way to fight spam will undoubtedly save you a great deal of time and effort.
As the usage of internet is multiplying day after day, e-mail has become the most powerful and desirable means of communication. But some people are trying to annihilate its great reputation by introducing the spam into it. Spam is nothing but unsolicited, unwanted, irrelevant or inappropriate e-mail. They are also known as junk mails. Spam mails are basically aimed at wasting the time and as a result, money of the individuals who are at the receiving end. Many people get annoyed when they see their inboxes full of junk mails, which are hidden between the legitimate ones. This situation may lead to chaos as these people may inadvertently delete the legitimate e-mails while deleting the spam. Also, the spam mails can cause unnecessary burden over the servers by uploading lots of redundant data over them. Moreover, they may even contain viruses, spyware and trojans which can damage the whole system of the receiver.
Hence, people who are acquainted with these ill effects of the spam mails are on the constant look out for better and more advanced Anti Spam solutions to get rid of this menace. Therefore big software companies are continuously trying to develop Anti Spam solutions, spam blockers and e-mail spam filters. Anti Spam solutions are basically designed to check the sender’s name and address and filter the spam e-mails according to a black list of spammers they own. They may also check the recipients’ names and addresses and filter the spam mails according to certain parameters decided by them. Some Anti Spam solutions also use content filtering or Bayesian Logic. They can scan the e-mails and search for certain words or phrases which are common in most spam mails like ‘viagra’ or ‘click here’ and filter the spam e-mails accordingly.
However, these Anti Spam solutions are not infallible. If the software companies are trying to develop more and more advanced ways to block and filter spam, the spammers are also not sitting idle. They are also constantly inventing new ways to hoodwink these Anti Spam programs and cause havoc in the world of internet. Moreover, most of these Anti Spam solutions are not reliable as they may delete some very necessary e-mail taking them as spam. This might happen if a legitimate sender makes use of some of the terms which favorites among the spammers or use an IP address that has been used by spammers in the past. Thus, a reliable Anti Spam solution is one, which minimizes these false positives by adopting a comprehensive anti spam approach by examining both the message content as well as the history of the sender. Moreover, an effective anti spam software is one, which learns the user preferences by analyzing his behavior towards some particular messages. For instance, most of us may delete the messages containing the word ‘viagra’ but some medical organizations may not do so.
Thus, while no Anti Spam software is perfect, still we should use them to reduce the risk of getting plagued by the menace of spam mails.
