Rule From Address not in Address List

I'm trying to crate a mail filerting rule (Outlook 2010) which moves mail from a given sender into a given folder. My observation, though, is that I can only add senders which are in my address list.

I can enter a freeform text in the Search field, but if that item is not found in the address list (in the image, I have selected GAL, but even if I select "All"), then it cannot be added to the list of recipients to whom the rule applies. The From button never becomes highlighted. The OK button becomes highlighted, but if I hit OK, I find that no recipient address has ben added to the rule.

Is it possible to add a recipient to a rule if they are not in my address list? How?

Thanks.
