Junk E-mail protection level

This policy setting controls your Junk E-mail protection level. The Junk E-mail Filter in Outlook 2007 is designed to intercept the most obvious junk e-mail, or spam, and send it to users' Junk E-mail folders. The filter evaluates each incoming message based on several factors, including the time when the message was sent and the content of the message. The filter does not single out any particular sender or message type, but instead analyzes each message based on its content and structure to discover whether or not it is probably spam.

If you enable this policy setting, you can select one of the four listed options available to users if you do not configure this policy setting. After you select an option, users will not be able to change it.

If you disable this policy setting, Outlook reverts to the user-defined protection level.

If you do not configure this policy setting, users can choose from four levels of junk e-mail filtering:

- No Automatic Filtering - Outlook does not evaluate incoming messages by content. Outlook continues to evaluate messages by using the domain names and e-mail addresses in the users' Blocked Senders Lists, and continues to move messages from blocked senders to users' Junk E-mail folders.

- Low - Outlook only moves the most obvious spam messages to users' Junk E-mail folders. This level is the default setting.

- High - Outlook intercepts most junk e-mail, but might incorrectly classify some legitimate messages as junk. Users are advised to check their Junk E-mail folders often.

- Safe Lists Only - Outlook moves all incoming messages to users' Junk E-mail folders except messages from someone on users' Safe Senders Lists and messages sent to mailing lists on users' Safe Recipients Lists.
