I just upgraded to Leopard and I'm setting up all my email accounts. I get to Yahoo Plus and I can't send! I've verified all the settings they have you use, but it's not sending. I can't see what I'm doing wrong.
I've had never-ending issues (I'm still having them!) with Yahoo Plus. Yahoo SMTP rejects the password. Incoming is fine, but outgoing refuses to work. The only solution I have is to use another SMTP server (perhaps your ISP's).
