Old email contacts
When I start to type a name, email contacts pop up which is good. However, I don't always notice that an old email address is also in the list and I discover it when I learn my email was undeliverable. Even though the correct current email address is in my contacts, Yahoo will still include an old email address it finds from old emails. This is annoying. How do I stop Yahoo from offering up the old one when a newer address for that person is in my contacts?
