Clear the "to" field cache of old mail addresses

When I write a mail and want to write the receiptiant’s mail address in the “To” field, Notes suggest some addresses. Some of them are from the address book and the directory, but some are addresses I have written myself before. Is there a way to clear that “cache” of before-written addresses? Some of them are old and I will never write to them again, so it’s annoying that they pop up.
