Though it integrates well with Microsoft Outlook and catches a majority of spam, InBoxer for Outlook requires continual hands-on attention. Also, be aware: it works only with Microsoft Outlook, not Outlook Express. You control its operations through an add-on Outlook toolbar. InBoxer analyzes incoming e-mail and sends it to a blocked folder, a review folder, or your in-box. Questionable e-mail gets sent to the review folder, where you can press the thumbs-up or thumbs-down button on the toolbar to mark a message as OK or spam, respectively. Likewise, you can give e-mail in the blocked folder a thumbs-up and e-mail in your in-box a thumbs-down. In theory, InBoxer learns from your input and improves its filtering. In our tests, we found that InBoxer did indeed catch most spam messages without blocking newsletters we subscribed to. However, the work flow required us to spend a lot of time marking e-mail in the review folder. InBoxer offers a few other features, such as spam analysis and a trust list, the latter of which lets you whitelist or blacklist individual senders or entire domains--a useful option. In sum, InBoxer is a good antispam filter with significant limitations. For Outlook users, it's worth a look.
Award-winning Outlook spam filter removes spam while making sure you see the messages you need. The optional plug-ins remove spam stored remotely for the BlackBerry, Treo, and other hand-held devices. InBoxer Anti-Spam Filter automatically builds a custom filters for you based on your mail folders using Bayesian and other language-analysis techniques for better accuracy. No two installations are the same, which makes it harder for spammers to beat. You also may define trusted senders, companies, and even your entire contact list. InBoxer learns from mistakes and usually won't make the same mistake twice. It becomes smart enough to allow a newsletter about your favorite hobby, even if others might consider the message spam. It can even learn the difference between an intimate note from your spouse and offensive mail from a bulk mailer. InBoxer does not work with Outlook Express.
