Known spam/Suspected spam
To intelligently apply resources, Policy Patrol Spam Filter pre-classifies spam as known or suspected spam. This allows you to delete known spam and concentrate only on the suspected spam. In this way, users can simply review the suspected spam in their quarantine reports or junk mail folders, instead of sifting through a daunting list of daily spam messages that can easily exceed one hundred emails per user, per day. Spam quarantine reports
With the email quarantine report, users will never miss a legitimate email again. Users can quickly skim through the list of newly quarantined spam messages from within Outlook and deliver emails or white list addresses (even before the email is received). Effective anti-spam techniques
Policy Patrol uses a multi-layered approach to detect spam, utilizing real-time DNS black lists, SURBL lists, sender and recipient verification, heuristic filtering and Bayesian filtering. Especially effective is greylisting, where Policy Patrol can reject initial emails from new senders for one minute. Legitimate emails will still get through, but spam messages will not. This is because unlike spam engines, regular mail servers resend their messages upon initial rejection. In a similar way, greylisting can also stop viruses from zombie machines, even before they have been detected by anti-virus vendors. Quarantine, delete, or forward to junk mail folder
Policy Patrol Spam Filter can reject (i.e. not download messages that are listed on real-time black lists or do not have valid recipients), quarantine (i.e. place spam messages on hold on the server), delay, delete, add a custom header or add a tag to the subject of spam messages. Alternatively Policy Patrol can forward spam to the user’s junk mail folder. Challenge & Response
Policy Patrol Spam Filter includes an advanced anti-spam challenge/response system, allowing you to configure when a challenge/response request should be sent. For instance you can configure Policy Patrol Spam Filter to only send a challenge/response message if there is a reason to suspect spam. The sender will be able to verify the message through a website, upon which the message will automatically be delivered. Anti-Spam Reports
Policy Patrol Spam Filter includes several anti-spam reports providing an overview of the number of spam messages received, the top spam domains, spam senders and spam receivers, DNSBL and SURBL lists results and much more. Anti-spam reports can be automatically generated and emailed to specified users. Build your white list
With Policy Patrol Spam Filter you can import recipients from Sent Items as well as automatically add any recipients of new outgoing emails to your white list. |
