We'll look at each type of spam filter and at the end you should be able to decide what spam filter is right for you.

Integrated spam filters

This type of spam filtering software is the most common. Once installed it sits "on top" of your existing email software and installs a new set of buttons into your email software. In future when you collect email you'll see options for marking email as Spam, marking the email as Not Spam, Bounce the email back to sender, etc. The description and position of these buttons varies from one product to the next but their purpose remains the same.

Most integrated spam filters automatically place suspected junk email into a separate folder on your PC for you to review or delete later on.

Why Your ISP Takes Bribes From Spammers

tag : Why. ISP. Takes. Bribes. From. Spammers.

The lifeblood of the spammer is email. They need to be able to send lots of it on an ongoing basis to stay in "business". High profile spammers can send 80 million pieces of junk email every single day. Yes one single person.

ISPs all over the online world have vowed to stop spammers sending such vast amounts of email through their mail servers. Do they really keep their word? All the end user sees is that the spam keeps coming. There must be a loophole there somewhere. There is.

In the soft white underbelly of the internet there exists something known as a pink contract. The term pink contract comes from the color of the famous tinned meat that junk email gets its name from. A pink contract is simply a business agreement between the ISP and the spammer. The spammer agrees to pay the ISP to turn a blind eye to the junk email passing through their mail servers.

Surely this is bad business for the ISP? Well the answer to that is both Yes and No. Yes it's bad news for the people who receive the junk email and No it's good news for the ISPs bank balance. A monthly pink contract can pay the ISP amounts from $10,000 upwards. Bearing in mind that the average work-at-home spammer averages $100,000 net per year the above figure is small change fo the bigger junk email vendors (the guys who earn $200,000 - $400,000 per month.)

The Cybermagic of Whitelists

tag : Cybermagic. Whitelists.

Before we start getting deep into the meat of this article it's important to explain some standard terminology to make sure the rest of this article makes sense.

• An IP address is a number which identifies your location on the Internet.

• A blacklist is a list of IP addresses which your antispam software uses to block incoming spam.

• A whitelist is the exact opposite of a blacklist.

A whitelist is a predefined list of IP addresses that are allowed to send email to and receive email from each other. Blacklists exclude known and suspected spammers. Whitelists can be used to exclude everyone except known IP addresses. Think of it like this. A whitelist is a like having a phonebook which is owned by a small group of people who only wish to speak directly to each other. They don't want just anybody ringing them. Not only that but the entire group need to approve new phone numbers before they appear in this exclusive phonebook.
