In our opinion, the antispam app Qurb 3.0 (pronounced "curb") easily bests phishing scams, and a great Outlook e-mail search tool. But Qurb also trapped more legitimate e-mail than MailFrontier and required more care and feeding. That said, Qurb is a very close second to MailFrontier, and is also recommended.and and provides serious competition for our current favorite, . Qurb exceeds MailFrontier in spam-fighting effectiveness, blocking nearly all the junk inside Microsoft Outlook and Outlook Express. It also offers a better interface for reviewing blocked mail, unique tools for fighting
We found Qurb's setup both quick and easy. Qurb installs a toolbar inside Outlook and Outlook Express and scans your e-mail as it downloads. E-mail from anyone not on your Outlook contact list or approved list gets shunted to a quarantine folder for you to review or delete. Qurb also allows you to issue a challenge e-mail to new senders, who must respond before their e-mail is delivered to you. As with MailFrontier, the challenge feature is set to be off by default. And like MailFrontier, Qurb will block e-mail created using foreign-language character sets.
Whenever you inspect the contents of the Qurb quarantine folder within Outlook, the app opens a pop-up window that displays the folder's contents with tools to redirect legit mail blocked by mistake. Passing your mouse over any entry allows you to read the first few lines of each message, helping you to separate the spam from legitimate e-mail without having to open it. Like MailFronter, Qurb automatically moves the not-spam-designated messages to your Inbox and adds those addresses to your approved list so that they won't get blocked again.
