It looks like you are trying to relay your outbound mail
through Yahoo. Are you doing this intentionally?

If you have a full time connection to the Internet, you
should either have exchange deliver mail directly or
relay through your ISP's smtp.

Yahoo is not designed to be a server mail relay. It
expects a legitimate @yahoo.com sender address and the
appropriate userid & password.

Go to your SMTP config and remove the "smarthost"
settings (which are apparently set to Yahoo)
