Spam is a reality of the Internet, but not all users suffer from it at the same extent. 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. Starting from this option that allows one to determine which incoming email is spam, the user may stop the access of unsolicited mail messages at the gateway or at the mailbox. Initially there were tools that pre-dated the release of Exchange spam blocker. Nevertheless, the older technologies are no longer supported by updates, as it happens with the modern variants of the email protections. The current version of the Exchange spam blocker is capable of stopping spam in the tracks, allowing for good business development.
The Exchange spam blocker 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. Once the identification is complete, it is up to the computer user to decide whether to keep or delete the messages. 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 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 import or export blocked messages or send domains. One further inconvenience is that the user has no clue about how much spam gets blocked and how well filters are functioning. It is important to check the settings and find out about the best mode to operate with the tool so that you can maximize the usage of your anti-spam defenses.
