CA allows mail from people you know your whitelist and quarantines everything else. POPFile is clearly the favorite free program of reviews. Did not fare well intests at Filter. Government and independent studies show spam is increasing.

Its Bayesian filter requires a time commitmentto train. Once you sign up, you need do nothing else. Since Email isnt downloaded to your computer, system performance isnt impacted and spam never makes it to your computer. Both are covered in this report. Because no spam filter is perfect, experts say could still get some false positives. Althoughthe product is ranked as the third most effective by a couple of sites, themajority of reviews are unfavorable. Tschabitscher rates as at least average, but notes thatits blacklist is not wellmaintained. Googles Gmail, in particular, has received praisefor its spam filter. They site reasonswhy it isnt for everybody.

Pro and Cloudmark Desktophave been favorites of reviewers for years, and continue to receive the mostfavorable reviews. Some of the most reliable reviewers,such as Consumer Reports, PC World and PC Magazine are not uptodate in theircoverage. More importantly, the products arecontroversial because they can falsely identify legitimate email as spam calleda false positive.

More importantly, the products are controversial because theycan falsely identify legitimate email as spam called a false positive. Email is the best webbased spam filter. The opening article is devoted to spamprevention methods. Email will work with any operating system. It starts working immediately after the installation. Reviews like the communitybased approach taken by Cloudmark Desktop, which uses an evergrowing database of known spammers to filter messages. But if your ISP is still letting throughtoo much spam, you might try one of the antispam software programs includedhere.

Thats partly because Internet service providers are doing a betterjob of weeding out spam. Freespam filters dont get great reviews in general. CA is whitelist based, so its best for those who receivemail mainly from the same people. Its more complex to use than the best commercial programs, and supportis.

Stopping Spam Email

By: Julian Marcellino

I check my email every morning and 90% of the stuff in my inbox is advertising related content. It’s frustrating because although my internet service provider does offer anti spam software on their email servers, I’ve had it block emails that were actually legitimate and meant for me -- emails from friends overseas or friends emailing me with their work emails, so in turn I had to turn the ISP filter off.

Of course, without any filters running, I would have to filter through all my emails manually every morning. It started to become a problem as the amount of spam emails continued to increase, and eventually I would wake up with 100+ spam emails every morning, with only 5 or so out of the 100 actually being legitimate.

I started to realized that stopping spam email in it's tracks was not so easy. I also became overly frustrated as I started to research for some software that would run on Microsoft Outlook, rather than on the ISP side on their servers. I installed and ran a handful of filters on my computer at home, unfortunately I kept being disappointed. The filters were either time consuming to use or blocked emails that were meant for me (I’m talking about emails sent from University email accounts! How is that spam?).

I then started researching Spam more deeply and I came across an interesting idea. The idea is based around the way we as people manually filter our inbox. For instance, if you gave a stranger your email account they could no doubt filter your spam as well, it's not hard to see what is unwanted junk. So why is it so hard to make a software spam filter that will filter emails depending on their content? For instance, advertising related keywords appearing in the email more than once will automatically flag that email as advertisement or spam. It is easy for us to recognize a spam email, we see phrases such as Buy Viagra Now and we automatically know it's spam! Why can't software do the same thing?

I did settle for a reasonably good spam filter though, and I’ve been running it for almost a month now without any real problems. This kind of software is the closest we can get at the moment to being 100% reliable. Although, I must say it's been running so far blocking all spam emails without blocking one single legitimate email -- which is pretty good if you ask me!
