Change | The Change value is used to define what effect a matched word or phrase will have on the SCL score of a message. The Change can be any integer value. Should the word or phrase be matched, the change integer value will be added to the original SCL value. Should the value exceed the supported SCL value, it will be normalized to a 0 to 9 range. In addition to the Change can also use the MIN or MAX keywords. Any time a phrase with the MIN keyword is matched, the message is given an SCL of 0 regardless of any other weights. Any time a phrase with the MAX keyword is matched, the message is given an SCL of 9 regardless of any other weights. Any time there is both MIN and MAX matches for one message, the message is given an SCL of 0. |
Text | The word or phrase is specified here (supports Unicode phrases up to 1,000 characters) |
When you have created the registry key shown in figure above you need to restart the SMTP service in order to make the IMF update feature become effective.
The IMF updates will be available every first and third Wednesday of the month through Windows Update, Automatic Updates, WSUS and SMS technologies, and as you can see in following figure below the first IMF update is already available for approval via Windows Update, Automatic Updates as well as WSUS.
4）IMF integrate with Outlook
After a message makes it past server-based anti-spam defenses, the Outlook 2003 client can act on messages that have an SCL value greater than or equal to the store junk e-mail configuration setting in Intelligent Message Filter. Messages that exceed this server setting are sent to the junk e-mail folder in the Outlook 2003 inbox.
Outlook 2003 and Outlook Web Access for Exchange Server 2003 also allow users to create a list of safe senders from whom users always want to accept e-mail messages, as well as a list of blocked senders from whom users always want to reject e-mail messages. At the mailbox store, regardless of the SCL rating assigned to the message, Exchange delivers all messages from safe senders to the user's inbox and all messages from blocked senders to the user's junk e-mail folder. However, if the e-mail message has been blocked by the gateway threshold, it is not delivered to the user's inbox because the message is never delivered to the mailbox store.
