Asp.Net 发送 Outlook 电子邮件并获取此 5.7.57 SMTP 客户端未经过身份验证以在 MAIL FROM 期间发送匿名邮件

Question

我正在使用 asp.net c# 发送 Outlook 电子邮件。

当我运行此程序时，我在 (smtp.Send(fromAddress, toAddress, subject, body);) 处遇到错误，我在网上搜索并尝试解决，但什么都没有。请发送帮助。对此，我真的非常感激。

protected void btn_Click(object sender, EventArgs e)
    {
        string eml = "xxx@mymail.com";
        var fromAddress = "xxx@outlook.com";
        var toAddress = eml;
        const string fromPassword = "password";
        string subject = "Subject testing";
        string body = "Welcome..";
        // smtp settings
        var smtp = new System.Net.Mail.SmtpClient("smtp-mail.outlook.com");
        {
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.UseDefaultCredentials = false;
            System.Net.NetworkCredential credentials =
                new System.Net.NetworkCredential(fromPassword, fromPassword);
            smtp.EnableSsl = true;
            smtp.Credentials = credentials;
        }
        // Passing values to smtp object
        smtp.Send(fromAddress, toAddress, subject, body);
    }

在线：

new System.Net.NetworkCredential(fromPassword, fromPassword)

两个参数都有 fromPassword，而不是用户名和密码

new System.Net.NetworkCredential(fromAddress, fromPassword)
