Thunderbird also surpasses Outlook Express with its e-mail creation capabilities, at least on preliminary tests. It supports a wide range of HTML-style e-mail constructs, including tables, named anchors, and even a table of contents. It also provides more powerful image tools than those found in Outlook Express. Images can be easily resized and placed anywhere in the message. Like Outlook Express, Thunderbird includes basic text formatting and a spell-check feature. The Mozilla-bred e-mail client also includes what appears to be more advanced inbound-message processing. It includes a junk e-mail filter that can automatically flag messages it thinks are spam, with the option of automatically moving or deleting them. It didnt work very well at first, but the program can also be taught whats junk and what isnt. Thunderbird also includes a basic rule-processing capabilitywe found it equivalent to whats in Outlook Express, though with a somewhat different interface.
Mozilla has also made Thunderbird natively extensibleboth in terms of functionality and look and feel. Although only nine Thunderbird extensions are available today, more are likely to be released over time. The current list of extensions includes the ability to control your music player from within Thunderbird and a nifty way to use mouse gestures, instead of the keyboard, to read e-mail. Thunderbirds look can also be changed through downloadable skins. We couldnt test this feature, however, because the skins available on Mozillas Web site havent been updated from the beta, and therefore would not work with Version 1.0.
All in all, Thunderbird seems like a better e-mail client than Outlook Express. If you use POP or Web e-mail, give it a try. Chances are, you wont go back.
