Creating a Spam Filter Rule in Microsoft Outlook 2007

Potential spam or junk mail messages are flagged in the subject line of each message as POTENTIAL SPAM. This allows CU Boulder email users to filter spam and junk mail messages away from their inbox.

Enabling the Outlook Built-In Spam Filter

  1. Open Outlook, and select the Mail Navigation Pane from the bottom left corner.
  2. Click on the Tools drop-down menu, and select Options.
  3. In the Options dialogue box, in the Email section, select Junk Email..., as shown below:
  4. In the window that opens, choose the level of junk email message protection you want and click OK.
Note: Notice that "Permanently delete suspected junk email . . ." is not checked. It is important to check your Junk mail folder on occasion to make sure no legitimate email messages have been accidentally labeled as spam.

Customizing Junk Email Handling

You can customize the junk email filtering of Outlook 2007 in the following categories:

Safe Senders List

If an email message is mistakenly marked as a junk email message by the filter, you can easily add the sender of that message to your Safe Senders List. Email addresses and domain names on the Safe Senders List are never treated as junk email messages, regardless of the content of the message. Contacts are trusted by default and messages from them will never be treated as junk email messages. You can configure Outlook 2007 to accept only messages from the Safe Senders List, giving you total control over which messages you receive.

Safe Recipients Lists

An emailing list or group that you are a member of can be added to your Safe Recipients Lists. Any messages sent to the email addresses or domain names on this list will not be treated as junk email messages, regardless of the sender or content of the message.

To add a sender to your Safe Senders List or Safe Recipients Lists:

  1. Right-click on a message from the sender.
  2. Select Junk Email, and click either Add Sender to Safe Senders List or Add Recipient to Safe Recipients Lists.
