"Not in Contacts" rule?

[Gordon]

is there an add-in, or a workaround, that allows you to construct a rule
that will permanently delete mail if the sender is not in Contacts? (Outlook
2003)

TIA

Create a rule that deletes all messages and add the "except if sender is in
specified Address Book" exception.
