I'm having some trouble with Apple Mail and my att.yahoo mail account. It's pretty much always worked, but today it won't let me send mail. It says: The server email@example.com cannot be contacted on port 465. Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be delivered. I've tried all of the ports and it still doesn't work. Please help lol.
