When you want to be able to only receive email from specific people, it's called "whitelisting." You can create a whitelist in Outlook Express by using its Message Rules function. Here's how:

1. Click Tools and select Message Rules, then Mail.
   
2. Click the New button.
   
3. In the list of conditions, check the box labeled "Where the From line contains people."
   
4. Under Rule Description, click the link "contains people."
   
5. Click the Address Book button.
   
6. Add the people from your address book that you wish to allow to send you mail, then click OK to close the address book.
   
7. Click the Options button.
   
8. Under "Apply rule if," click "Message does not contain the people below." Click OK.
   
9. Now under "Select the Actions for your rule," either check the box that says "Delete it" or, if you want to be more cautious, create a folder called Quarantine and check "Move it to the specified folder." That way, you can check the messages to be deleted in case there is mail there that you want to get.
