Deleting old autofill address not in address book?

How do I delete old e-mail addresses from Mac Mail that are no longer in the address book? I have deleted peoples old addresses from the address book application, yet when I start typing their name in the "to" line, all these old addresses still show up and get in the way of going right to their latest and current e-mail address.

 

Thanks, did a search, found nothing. That fixed it. I was looking under mail preferences ----> composing ------> automatic address filling.

Thanks guys
