Exchange 5.5 的SMTP验证的问题！！急

[byteman]

Exchange 5.5 的SMTP验证到底该怎么做？？我作了验证后就收不到Internet邮件，错误信息：From: MAILER-DAEMON
Email: [e-mail]

sina.com.
邮件无法发送到您指定的地址中。
在邮件传输过程中由于外部的无法避免的错误导致邮件无法送达。
505 Authentication required

Of course, Sina SMTP server does not know one valid username/password in your domain, how can you expect it to pass the authenticate?

For other settings to avoid such problem, please see the online help.
