The Exchange Spam Blocker : A Smart Tool Designed for Mailbox Protection

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. Software companies have come with solutions in the form of anti-spam programs meant to detect and delete over 90% of junk mail. One intelligent tool is the Exchange spam blocker first released by Microsoft in May 2004. Both individual and business users can benefit from the functions of the program regardless of the extent of the mail exposure.

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. Other Microsoft tools were used before the launch 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 is capable of stopping spam in the tracks, allowing for good business development.

The Exchange spam blocker relies on a combination of techniques meant to identify the messages that could be spam; thus, other than the use of the Bayes filter, the the messages are scanned for spam headers and spam keywords. After the identification of the spam messages, the delete or read-mail options are controlled by the PC user. There are versions of the Exchange spam blocker that even notify a sender if his/her legitimate message has been taken for spam or not. Plus, the benefits of preventing spam directly on server before reaching the computer are manifold: there is no malware unauthorized installation or virus attacks.

All in all, most of the tasks required for small business operations and personal usage should be covered by using the Exchange spam blocker. An issue with the 2003 version of the blocker used to be the impossibility to import or export 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 test the settings and learn about the best operational mode in order to optimize the usage of your anti-spam defenses.
