I've always been a fan of the Thunderbird open source email client, especially since v2.0 came out earlier this year, but have stayed with Outlook Express because Cloudmark Desktop - a highly effective anti-spam service - is available for this good ol' email client.
Now it seems that Cloudmark has heeded the requests of punters and has announced it will release a version of its Desktop anti-spam/phishing application for Thunderbird in a couple of weeks.
If you can't wait that long, or haven't tried Cloudmark to block your spam, the firm is beta testing its Desktop 3.2 client of Outlook Express, which supports SSL connections to email servers for the first time.
In addition, whilst the product is in beta, the company is not charging punters for the service.
