I've quoted some helpful highlights for you:
Mail (Mountain Lion): Make a sender a VIP
To keep track of messages you receive from especially important people, make them VIPs in Mail. You can have up to 100 VIPs.
- To make someone a VIP, move the pointer to the left of the sender’s name in the message header and click the star that appears. You can also move the pointer over the sender’s email address, click the arrow that appears, and choose “Add to VIPs” from the pop-up menu.A mailbox for the VIP is added to the Favorites bar. For example, if you make Dad a VIP sender, his messages are displayed in a VIP mailbox titled Dad.
- To remove VIP status from a sender, click the VIP’s star in a message. The star is removed and the sender’s VIP mailbox is removed from the Favorites bar.
The instructions above work if a message is actually open. Move the pointer to the left of the sender's name in the message header and click on the star that appears.
Another way to do this is look at the sidebar on the left. The VIPS are listed with a Star.
You may need to click on the disclosure triangle to the left of the word VIP to expand the list and see your contacts. Right click or control click on the contact name and choose Remove From VIPs.
I hope this information helps ....
Have a great day!
