Spam software is one of the most commonly employed tools against spam. There are many available spam softwares in the market today. They make use of a variety of methods and techniques. In choosing the right spam software for your company, you should at least know the concept behind them. This will help you choose the most suitable spam software to meet your needs.

Spam filter's objective is to clear your inbox from unwanted messages that is spam mail protect. This is primarily done by analyzing the received email and marking it as spam or legitimate. The analysis varies depending on the type of filter used - content-based filter, white list-blacklist filter, etc. Though filters vary in detecting spam, the important features are quite the same and true to all spam filters.

The primary feature of a filter is its capability to detect spam. Once a new message prompts, the filter gets an alert and automatically checks if it is suspicious in nature. The checking could be based in the content, subject line, HTML code of the message, or the blacklist and ...
... whitelist embedded on the filter by the user. If the message is confirmed as spam it will be placed in a junk folder or deleted instantly, depending on the chosen option.

In addition, spam filters use point system. Messages coming from unknown senders are given corresponding points. This means that the higher the points the more 'spammy' the message is. This message is either blocked or deleted automatically depending on the scale given by the user, say 5 'spammy' words or symbols in a message will cause it to be blocked (delivered in the junk folder) and 10 'spammy' words or symbols will cause it to be deleted. But remember not all blocked emails are spam, some are legitimate.

If your IP or email address is included in the blacklist, your emails will not be received unless you apply for white listing. Another feature of a spam filter is its ability to update blacklist and whitelist. If the address is not found in either the blacklist or the whitelist, the filter checks the message. Whenever the message is confirmed as spam, the email address on which that message came from is added to the blacklist. But if the message is accepted due to further actions done by the sender, to confirm his intention, the address is added to the whitelist database.

A lot of emails contain attachments where in some cases, unlikely graphics, pictures and messages are embedded. Spam filter can also check not only the message but as well as the files attached on it. They accordingly block them. Some of the programs filter the emails based on the keywords used in the mails. Some of the spam mail blockers are configured and you can easily customize it or the network administrator can also customize it according to the requirement of the company. With the help of their unique features, the spam filter gives you a clear and spam free inbox.
