No anti-spam vendor claims 100% accurate spam filtering - which is precisely why Policy Patrol Spam Filter for Exchange 2007/2010 includes an email quarantine report that allows users to quickly scan through the list of newly quarantined spam messages in Outlook and deliver emails and white list addresses.
Instead of just placing all spam in the junk mail folder that users forget to check, the user is now reminded to scan a list of quarantined emails, which enables them to detect any incorrectly quarantined messages. With the Known Spam/Suspected Spam classification, the user does not waste time on known spam, but only scans over the suspected spam messages.
