Policy Patrol Spam Filter offers advanced anti-spam using Bayesian filtering, header and keyword analysis (including word pattern matching), RBLs, SURBLs, checking for illegal HTML, remote images and more. Spam messages can be quarantined, deleted and can include a header or tag. By blocking unwanted mails, Policy Patrol Spam Filter reduces network traffic, saves bandwidth and improves employee productivity. Policy Patrol is the first Exchange spam filter add-on to provide support for SURBL Lists. Policy Patrol is easy to install and configure, and its powerful rules wizard allows you to create customized user-based rules by specifying conditions, exceptions and actions. Each rule can be scheduled by date and time. Policy Patrol ships with several sample anti-spam rules that can get your email system fully protected within minutes after installation. Policy Patrol works with Exchange Server 2003, 2000 & 5.5, Lotus Domino and any other SMTP mail server. The product takes full advantage of the Active Directory structure, which enables you to select users, groups, public folders, domains and contacts from the Active Directory, and to retrieve user properties for merge fields. If you do not have Active Directory, Policy Patrol can also retrieve users & groups and their properties from Exchange Server 5.5 and Lotus Domino. Alternatively you can import users from a text file or manually enter users and their email addresses.
