I have used Cloudmark Desktop for several years to fight my Microsoft Outlook email spam. I believe it is the best product available, bar none. To provide a quick high level summary, Cloudmark uses the contributions from its users to determine what is and is not spam. Through its algorithms, Cloudmark is able to rate its customers' feedback to provide an accurate assessment of each email that enters your inbox. Very little spam actually makes it through to my inbox, and I get virtually no false positives. I am a highly satisfied customer.
Cloudmark has just released its public beta for the Thunderbird email program. For those who use Thunderbird, you might wish to consider using Cloudmark as your protection against email spam.
By way of disclosure, the link for Cloudmark Desktop for Microsoft Outlook is a referral link, meaning that I receive a nominal fee if you decide to use Cloudmark. The link for the beta for Thunderbird is not a referral link. In other words, it is free and clear.
