Question

我正在尝试通过以下操作方法发送电子邮件

    [HttpPost]
    public ActionResult ForgotPassword1()
    {
        dbAlKhaleejEntities _context = new dbAlKhaleejEntities();
        var email = Request["Email"];
        var email_adress = _context.CUSTOMERs.First(em => email == em.CUSTOMER_EMAIL);
        var mailto = email_adress.CUSTOMER_EMAIL;

            MailMessage msg = new MailMessage();

            SmtpClient client = new SmtpClient("smtp.gmail.com");
            client.Credentials = new NetworkCredential("umairliaquat63@gmail.com", "abc");
            client.Host = "smtp.gmail.com";
            client.Port = 587;

            msg.From = new MailAddress("umairliaquat63@gmail.com");
            msg.To.Add(mailto);
            msg.Subject = "Password recovery";
            msg.Body = "Test Recovering the password";
            msg.IsBodyHtml = true;
            msg.Priority = MailPriority.High;


            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.EnableSsl = true;
            client.UseDefaultCredentials = false;

            client.Send(msg);
            return RedirectToAction("forgetPassword");
  }

但在“client.Send（msg）”行，它抛出异常“SMTP服务器需要安全连接或客户端未经过身份验证。服务器响应为：5.5.1需要身份验证”。我该如何解决这个问题

Answer 1

据我所知，您不需要编写自己的代码，因为SmtpClient可以使用您的配置：

<system.net>
  <mailSettings>
    <smtp from="It's me &lt;its@my.email&gt;">
      <network host="smtp.ip.or.domain" port="527" defaultCredentials="false" userName="noreply" password="12345" enableSsl="true"/>
    </smtp>
  </mailSettings>
</system.net>

验证您的邮件设置两次。此外，SMTP服务器可以拒绝黑名单中的IP连接，也可以拒绝白名单中的IP连接。 SMTP服务器可以将您的邮件检测为垃圾邮件。

您可以使用自己的本地SMTP或专门的服务进行群发邮件。

试试这个代码段：

 using (var client = new SmtpClient(SmtpServerHost, SmtpPort)
  {
    Credentials = new NetworkCredential(NetworkCredentialUserName, Password),
    EnableSsl = this.enableSSL
   }
   )
    {
      MailMessage msg = new MailMessage();          
      msg.From = new MailAddress(FromMailingAddress);
      msg.Subject = this.Subject;
  }
