How Does a Spam Blocker Work?

A spam blocker is one way you can effectively cope with the deluge of spam that is targeted at your inbox each day. This type of anti-spam software works by blocking any unsolicited email from getting to your inbox. It is generally about 90% effective in blocking this spam, along with any viruses and other malicious code that may come with it.

The spam blocker differs from a spam filter in that its function is specifically to block most of the incoming spam. The spam filter works by organizing email that it identifies as spam into folders, and leaves it to you to take further action on. The spam blocker, on the other hand, is specifically programmed to prevent spam from getting through. With a spam blocker, you do not have to deal with the spam it detects and blocks.

So How Does a Spam Blocker Work?

The spam blocker will log into your mail server email account every 10 minutes, inspecting it for spam email. It immediately destroys any viruses, and gets rid of any obvious spam such as email that contains adult or pornographic material. Undesirable email is flagged and then redirected to a folder specifically for spam. You will have an opportunity to sort through this spam folder to verify that no legitimate email is mistakenly diverted there. Any email that it is on your white-list or which it determines as legit will be left on the server to be downloaded as normal.

If an email is from an unknown source and the spam blocker cannot clearly categorize it as either legitimate or spam, it is quarantined in a specific folder until you either move it or delete it. The quarantined spam is usually held in this folder for up to 30 days, or until you take action on it. The spam blocker keeps track of the particular action you take on each quarantined email e.g. if you delete the email. It will "remember" this action and use it to create a new filtering rule that it will apply to future incoming email.

What are the Benefits of a Spam Blocker?

- A spam blocker frees up storage space. Most mailboxes have a very limited capacity to store email. Spam takes up space, and a spam blocker generally prevents large files from making it into your main folder.

- By blocking spam rather than just filtering it, the spam blocker helps minimize the amount of time you have to personally sort through your spam email.

- Because this anti-spam software deletes spam, it drastically lowers the risk of a computer virus infecting your system.
