Automatic recipient fill-in messes up

When I type in a recipient's name, Thunderbird automatically guesses at the email, but sometimes produces addresses no longer valid (even though I've deleted them from my address book.) I end up sending messages that bounce. How can I delete those invalid addresses?

How about checking the answer to your first question before asking the same one again?
