How to Whitelist

 

In Outlook Express
Go to: Message
Go to: Create Rule from Message
Go to: Section 1. “Select Conditions for your rule”
Check box “Where the From line contains People”
Section 2: Choose check box “Flag it”
Section 3. “Rule Description (click on underlined value to edit it) Where the From line contains:
Select People
Click “Add”

Then OK, Then OK

Mike (E) says if you have Outlook as opposed to Outlook Express, simply go to Rules and Alerts in Outlook, then to "New Rule"  then exactly same as for Outlook Express.
