错误的命令序列。 [英] Bad sequence of commands.

问题描述

我在发送邮件时得到了这个：



错误的命令序列。服务器响应是：此邮件服务器在尝试发送到非本地电子邮件地址时需要身份验证。请检查您的邮件客户端设置或联系您的管理员以验证是否为此服务器定义了域或地址。

 SmtpClient sC =  new  SmtpClient（  domain.com）; 
 sC.Host = ConfigurationManager.AppSettings [  servername]; 
 sC.Port =  25 ; 
 sC.Credentials =  new  System.Net.NetworkCredential（  username，  password）; 
  //   smtp.EnableSsl = true;  
 
 sC。发送（mM）; 

解决方案

domain.com提供的构造函数将替换为您从应用程序设置中指定的Host属性，使用其中一个属性并给出smtp主机名正确，例如它是gmail smtp smtp.gmail.com

I have got this this during mail send:

Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.

SmtpClient sC = new SmtpClient("domain.com");
                sC.Host = ConfigurationManager.AppSettings["servername"];
                sC.Port = 25;
                sC.Credentials = new System.Net.NetworkCredential("username","password");
//smtp.EnableSsl = true;

                sC.Send(mM);

解决方案

"domain.com" which provided in the constructor will be replaced by the Host property you specify from the app settings, use one of those properties and give smtp host name correcty, for example is it is gmail smtp smtp.gmail.com
