Top Anti-Spam Filter Reviews

In the race to provide the best anti-spam system to fight the ever-growing threat of spam email, there are a few which stand out among the for-pay software systems. Some are software programs, while others are web-based systems that function by sending your email through their service before it gets to you. The web-based filter has the added benefit of not permitting spam to get through to your system, in the first place; on the other hand, if valid email is filtered out and isn't spam, its difficult to recover it.

Here are reviews of top-rated spam filters

Mailwasher:

The Mailwasher spam filter is a very efficient and secure spam filtering tool. It combines a number of different techniques to detect and delete spam before it gets to your inbox, as well as protecting your computer from viruses. These techniques include: using statistics, blacklisting and white-listing, databases and advanced learning filtration.

Mail Washer supports IMAP and POP accounts, as well as MSN, AOL and Hotmail. However, it does not offer IMAP or POP proxy filtering.

This spam filter takes a bit of time to "learn" what you think is spam, and in time will be highly efficient in its spam filtration.

Only My Email:

Is on an online web based filtration system, so there is no software to download or install. Because it is not downloaded to your computer itself, the spam filtering operations will never affect your computer's performance. Your email is filtered prior to coming to your computer and the spam will never be downloaded to your personal machine. You also get a daily spam report.

Only My Email is an extremely accurate anti-spam filter. It is capable of filtering up to three IMAP or POP email accounts.

Cloudmark Desktop:

This is a great, easy to use anti-spam filter. It is a plug-in for Outlook and Outlook Express. This software is highly accurate, with a great spam detection rate and relatively low false positives.

Cloudmark Desktop uses a database of spammers to identify and filter out spam. This database is updated by the community of over a million Cloudmark users. For example, when you identify a message as spam, it is automatically deleted from other Cloudmark users' inboxes as well. Phishing spam faces the same fate. This spam filter deletes spam immediately or moves it into a dedicated folder for further action from you or later deletion.

Cloudmark Desktop is a subscription service that needs to be renewed annually. There are still some areas in which improvement is needed such as in the case of false positive spam removal, but all in all, it is a great spam and phishing email solution.

CA Anti-spam

Previously known as eTrust Anti-Spam, this software is a whitelist spam filter. This means that it will only permit mail from those you have added to your whitelist and will quarantine all other emails. Once approved, messages from a previously quarantined sender will be moved to your inbox. It also updates your whitelist by scanning you outgoing email.

While CA Anti-spam works well for those who receive only mail from those they know, but may not be practical for those who receive large volumes of email from several legitimate but unknown sources.

Spam was once just clutter in your inbox; now it is a commonly used vehicle for fraud, electronic crime and even corporate espionage. The 4 Ws of spam answer the most commonly asked questions about spam.

What is Spam?

Spam, also called junk email, is generally defined in the Internet industry as unsolicited commercial email (UCE). It is email that is sent out in bulk to a huge number of recipients who did not request it. The contents of spam range from benign advertising to malicious programs that can literally hijack your computer system do grave damage.

The most common commercial spam advertises pyramid schemes, pornographic web sites, mortgage loans, chain letters, credit repair, fraudulent pharmaceuticals and illegally pirated software. The more dangerous spam will often contain viruses that can infect your computer, Trojan horses that can hijack your email program and use it to send out spam to your friends and family, and phishing scams that attempt to get your personal and financial information.

Who Spams?

"Spammer" is the term used to refer to those responsible for spam. In the Spam world, there are two types of spammers. There are the honest spammers who comply with the anti-spam laws, and have the consent of the spam recipients. These willing recipients usually join the honest spammer's "opt-in" mailing list by signing up at a website, for example to enter a lottery, or to be notified of future promotions.

Then there are the dishonest spammers, who will get your email addresses by any means possible. They use their spam for criminal or malicious purposes and have zero regard for the law.

Spammers range from the lone, home-based individual to multi-million dollar companies with several employees. Most of the spam companies are increasingly relocating to offshore locations to evade US laws and law enforcement.

Where do the Spammers Get your Email Address From?

Spammers get their victim's email addresses from just about anywhere you can imagine. Primarily, they use Newsgroup harvesters and Spambots, which are automated programs designed to "harvest" (extract) email addresses from online sites. Newsgroup harvesters target newsgroup postings and other unprotected web-based forums, which tend to have low security. Spambots troll the Internet, scanning websites and "harvesting" (extracting) email addresses. It typically searches for the "@" sign that denotes an email address.

The average spambot can harvest over 30,000 email addresses in just one hour. And this goes on 24/7, year and year out.

There are also companies that sell CDs that are packed with valid email addresses. These can sell for as little as $25, and they are a goldmine for any spammer.

Why do Spammers Spam?

In a word? Money. Spammers literally make millions from their illicit trade. Studies show that for every million junk emails sent out, a spammer will average about 100 sales. Add to this the fact that they make $50-$100 in commission for each sale, and you can see how the numbers add up to incomes in excess of $100,000 a year! What's more, spamming can cost next to nothing.

But why does spamming continue despite its cost in time, effort and money? Because there are people out there who respond to spam. Even with a minimal response rate of one sale from every 10,000 emails, it can be highly profitable. If no one responded to spam, the spammer's cash cow would starve and the practice would end. It is these few who keep the spammers in business. They make the cost of spamming worthwhile.
