Block spam with Cloudmark Desktop One

Protect your inbox from spam and other threats with this free tool.

Cloudmark Desktop One is an antispam tool for small and medium businesses, but it's free for personal use. It protects your e-mail account from spam, phishing, and viruses. It automatically configures itself to your e-mail account, but it works independently to protect you from threats even when your e-mail client is closed. It supports Outlook, Outlook Express, Windows Mail, and Mozilla Thunderbird with its optional integrated toolbar, and Gmail, Yahoo, Lycos, Hotmail, FastMail, and AOL without the toolbar. It offers separate downloads for 32-bit and 64-bit editions of Windows XP, Vista, and 7. We tried the 64-bit version in Windows 7 Home Premium. The freeware runs in Basic mode, which limits scans to one folder and disables automatic deletion of old spam and the trusted senders option.

Desktop One's installer let us select the free Basic version or activate the full Pro software. It automatically identified both our client (Outlook) and e-mail account and also let us configure Webmail accounts. We selected the client to enable full toolbar support, which included downloading and installing an Outlook add-in. The program's toolbar doesn't work with all combinations of Windows and Office, but it's optional. It lets you quickly enable or disable senders. Desktop One also has a small, separate interface for accessing the program's settings, including choosing which folder to scan. The program does its job in the background, automatically moving or deleting spam based on how you configure it with the Spam Action menu in the Account Settings. Under the Advanced Account Settings, we could disable the program when our e-mail client closes. The program also offers a different Advanced Settings dialog for proxies. The online Help file offers excellent documentation.

About the 32-bit and 64-bit downloads: Many users who run 64-bit versions of Windows actually use 32-bit editions of Office, on Microsoft's recommendation. The 64-bit download of Desktop One is for 64-bit versions of Windows running 64-bit versions of Office 2010. If you're running 32-bit Office in 64-bit Windows, you need the 32-bit version of Desktop One. The installer will tell you if it's compatible.
