An Introduction To Spam Filters

Using spam filters is another very effective way of combating spam or junk mail. These programs use some keywords like ‘guaranteed’, ‘free’, etc and block any email with those words in them. But this has the disadvantage of sometimes blocking even important mails from your contacts and preventing those senders from sending mails to your address again. The way out is to use add-on spam filters which allow you to control the content that should be allowed into your inbox. This will save you a lot of time and energy as you no longer will have go through each and every email before identifying it as spam and eliminating it.

Spam filters can be installed on any computer system and aim at filtering junk and getting only relevant information to the user.


Setting up a simple spam filter can be very easy. Identify the section ‘filters’ in your email program and create a new filter. Lay down the rules or filter conditions for the new folder. These can be the parameters under which an email would be marked as spam and deleted from your inbox. If you prefer to look at the filtered mail before deleting it, you can choose the option to move it to another folder once it is filtered. Once you save the changes you have made in the new filter, it will be active.

You have a new variety of spam filters in the market now which are called ‘smarter filters’. While these fight and prevent spam very effectively, setting it up is a very complex process and is recommended only for technical experts.

New generation spam filters are different from traditional ones in that they go in for statistical data rather features of spam. These filters decide on spam by analyzing the entire email and comparing it with other already identified spam mails. The error margin for these filters is almost zero as more than 99% of scams are identified and eliminated through this method.
