Security software company Cloudmark has made a version of its award-winning anti-spam software available for Mac users in both a free and paid version. In addition to supporting Apple's default Mail program and Microsoft's Outlook 2011, the company has added support for Mozilla's Thunderbird 17 and later email client, running on Snow Leopard (10.6.x) and later versions of OS X. The program acts as a plug-in to each of the mail programs, allowing users to set filters and flagging any potential spam or phishing emails.
