The error message you have received tells you that the SMTP server you have connected to requires authentication before you can use it to send an email, and that you haven't given it any authentication details.

您收到的错误消息告诉您，您所连接的 SMTP 服务器需要身份验证才能使用它来发送电子邮件，并且您没有为其提供任何身份验证详细信息。

See here (Internet Archive)for an example of how to send an email when the SMTP server requires authentication.

有关如何在 SMTP 服务器需要身份验证时发送电子邮件的示例，请参见此处 (Internet Archive)。
