MailFrontier Desktop 4.2 serves up powerful spam-fighting tools that are so easy, you don't even have to think about them -- exactly what you want from a junk-mail filter. The program's performance is outstanding, too. In our informal tests, with no training, it trapped more of the junk than Norton AntiSpam 2005 or McAfee SpamKiller 6.0, while tagging fewer legitimate messages (false positives). After just a few days of training, MailFrontier Desktop trapped nearly all of our junk with almost no false positives -- the best results we've seen from any desktop anti-spam filter.
Setup is easy: just download the 3.5MB install file and off you go (you can download a free trial here). The program automatically creates a toolbar inside Outlook or Outlook Express and sets up a folder to stash suspect messages. Note: we discovered the hard way that you can't import an address book once you've installed the product; you'll either have to reinstall or manually enter each address.
If MailFrontier Desktop misses a piece of spam, select it and click the Junk button. MailFrontier sends the message to its Junk Mail folder and adds the sender to your Blocked list. If it blocks a legit message by mistake, click the Unjunk button to put the email back into your Inbox and add the sender to your Allowed list -- overall, an easy process.
Hate combing through your MailFrontier folder looking for legit mail? Turn on the program's optional Challenges feature. When someone not on your Allowed list sends you mail, MailFrontier Desktop emails a challenge that the person not on your Allowed list must respond to before his or her message can reach your Inbox. Because virtually all spam is sent by automated computer scripts, only real humans will be able to get that mail past MailFrontier.
MailFrontier Desktop is far more configurable than Norton AntiSpam 2005 or McAfee SpamKiller 6.0. You can choose to block some forms of spam, such as sex or gambling ads, and not others. Like Norton AntiSpam, MailFrontier also lets you block any messages coming to you in a foreign language.
Another unique feature is MailFrontier Desktop's scam filter, which isolates potentially fraudulent email known as phishing scams. In limited tests, however, MailFrontier failed to identify any of the known scams we threw at it.
Unlike Norton AntiSpam 2005 or McAfee SpamKiller 6.0, MailFrontier Desktop provides only email support for its desktop users. Small-business customers get one free phone call, then must pay $100 (~£54) per incident; enterprise versions come bundled with support. We sent our email question on Friday evening and got an accurate answer the following Tuesday. That's a fine turnaround if you're a casual user, but business users will demand a quicker response.
