I’ve been a Firefox user for some time now. Thunderbird also looked intriguing, but I never installed it because I didn’t want to take the time to set up all the message filters and account info again. Well, I jumped the gun and installed the 1.0 release evaluation 2 days before Thunderbird’s 1.0 official release. (Might as well do it when I have the time!) So far, I’ve been very happy with the way it works. Configuring it is easier than Outlook, and I like the anti-spam options. Disabling remote-loading of images is “supposed” to help reduce spam, but we will see. Some sites apparently used the image load as a indicator that you’re reading their spam and send you some more. That’s a problem if you had Outlook’s the preview pane enabled, since images would load automatically and…bingo. The message filter wizard is much more intuitive than Outlook, and mail downloading is smoother. I don’t know how else to describe it, but when Outlook was downloading mail, it would “hiccup” while you’re reading. Once configured, Thunderbird doesn’t “feel” any different than Outlook, and I consider that a good thing. It doesn’t force me to acquire new habits. How it works behind the scenes, though, is reassuring.
