Qurb, recently awarded PC Magazine's Editors' Choice, is the safe, easy-to-use
solution for ensuring you see messages from people you know while blocking spam
from people you don’t. Qurb prevents spam from interrupting your work by only
sounding Outlook's new mail notification when a message is received from an
approved sender. Qurb quickly learns who you communicate with and updates your
whitelist of approved senders as you work. Sender confirmation, the most
friendly form of challenge/response, is an optional Qurb feature that helps
legitimate senders get attention for their quarantined messages. When sender
confirmation is enabled, Qurb will automatically send an e-mail message to the
senders of quarantined messages. If the recipients reply to the confirmation
requests, the original messages will be moved from the quarantine to the inbox
and their addresses will be added to the whitelist of approved senders.
Qurb works with Microsoft Exchange accounts as well as POP3 mail. The only major
drawback: It can't be used with anything but Outlook 2000 and 2002. Once you have installed
Qurb, the program automatically sets up your whitelist with addresses from
Outlook's contact database and calendar, messages you've sent, and those you've
saved. Not only does Qurb set up your whitelist, but it continually updates it when you send
an email to a new address.
