Exchange Spam Blocker

Anyone who uses the Internet is familiar with spam, but to some email users the phenomenon is more harmful and bothersome than for others. Business owners have difficulties with identifying real messages from interested prospects from unsolicited mails. For business and personal assistance alike, software companies have created special anti-spam programs meant to block the access of unsolicited mail to inbox in more than 90% of cases. One intelligent tool is the exchange spam blocker first released by Microsoft in May 2004. The target market for this product consists of individual users and companies that receive unsolicited commercial emails in very large numbers.Microsoft Smart Screen technology stays at the basis of the Exchange spam blocker as it is essential for the identification of the nature of the message. The access of the unsolicited mail messages can thus be stopped at the mailbox or at the gateway depending on the settings. Initially there were tools that pre-dated the release of Exchange spam blocker. At present, Microsoft no longer provides updates for the former intelligent filters, in a clustered environment. The present version of the Exchange spam blocker supports business development by detecting and stopping spam in the tracks.The spam blocker for exchange combines several technologies in order to separate spam from legitimate messages; thus, besides the use of the Bayes filtering, the tool scans the messages for spam keywords and analyzes the spam headers. After the identification of the spam messages, it is up to the computer user to decide whether to keep or delete the messages. There are models of the Exchange spam blocker that actually inform a sender whether his or her message has been treated as spam despite its inherent legitimacy. Plus, the advantages of preventing spam directly on server before reaching the computer are manifold: less virus attacks and no malware unauthorized installation.To sum it up, the Exchange spam blocker can support all the small business and personal operations conducted via email. An issue with the 2003 version of the blocker used to be the impossibility to export or import blocked e-mails or send domains. Another problem is the fact that the user does not know how much spam is blocked or how well the filters are functioning. It is important to check the settings and find out about the best mode to operate with the tool in order to optimize the usage of your anti-spam defenses.
