Rules And Tools To Filter Junk Email

Starting with Outlook 98, you may use either the Organize pane or the Rules Wizard to make use of the built in junk mail processing feature. However, by putting wanted senders in the junk mail folders and not ignoring items sent with no “From” address can be lead to unsatisfactory results. While Outlook 2003 and Outlook 2007, include the Junk Email folder, the end user cannot update it, since Microsoft releases regular updates for it. Since few spammers reuse addresses and the blocked lists are also of limited size, the technique of adding addresses to the blocked lists doesn't work.

The following explains how the Outlook has blocked and safe lists work.

Outlook 2003's Safe and Blocked Sender's lists: The maximum capacity of the safe and blocked lists in Outlook should not exceed 2000 addresses since the maximum size of the lists is 512K and Outlook alerts you once the limit is reached. Older versions have a larger capacity and hence Outlook may crash while trying to import them. The limit on the number of addresses is a means of improving performance. The lists are downloaded when the users synchronize with the Exchange mailbox. This limit could be adjusted by making the necessary changes in the required registry key.

Using Outlook's Blocked and Safe Sender's lists: Since it takes time to tinker around with the filters, Microsoft believes that the user should not spend too much time with them. While adding email, addresses to the lists that send spam would result in a long list of addresses that may never be used again. If one spends time, each day adding addresses to his blocked sender's lists it only means that he has to update his anti spam filters.

Built-in Rules Method: Outlook's filtering techniques for adult-content and junk mail filtering are based on a specific list of email addresses and an internal list of terms. There are steps to automatically move or delete E-mail messages based on content, sender, making an exception to your filtered content list, changing the destination folder to junk messages, adult-content messages.
