For the past year, I’ve been using Cloudmark SpamNet to filter my email against spam. It works as a plug-in with Outlook and Outlook Express. In my experience with it installed with Outlook 2003, nothing beats it in its capability to not only kill spam email before it gets to your inbox but also its oustanding accuracy in filtering real spam and not your legitimate email. It’s not a free product — you pay $4 a month for the license (you can trial it free for 30 days).
What’s especially interesting about SpamNet is that when you use it, the details about email you identify as spam (addresses, URLs, subject lines, and text) get notified to Cloudmark who maintains a continuously-updated database with information from the more than 1 million users, and who use this information to improve SpamNet’s filter accuracy. The program also checks for updates (tonight, it told me version 3 is now available) so you can ensure you have the latest version.
This spam buster is good. That’s not only my opinion — PC World magazine voted it the Best Buy in a review of spam filtering software in their June 2004 issue.
