I'm on a business trip at a hotel, using there wireless...... I'm unable to send emails from apple mail, though if I go to yahoo I can send emails.... this is the message I'm getting "This message could not be delivered and will remain in your Outbox until it can be delivered. The SMTP server "smtp.sbcglobal.yahoo.com" doesn't support authentication. Please check your account settings and try again." I checked the settings and nothing has changed....... Will my apple email be able to send emails when I get back home or is there something I need to do now?
