发送电​​子邮件使用System.Web.Mail [英] Send email with System.Web.Mail

问题描述

我想在ASP发送电子邮件。

I want send email in asp.

我用这个code

using System.Web.Mail;

MailMessage msg = new MailMessage();
msg.To = "[e-mail]";
msg.From = "[e-mail]";
msg.Subject = "Send mail sample";
msg.BodyFormat = MailFormat.Html;
string msgBody="Hello My Friend. This is a test.";
msg.Body = msgBody ;
SmtpMail.SmtpServer = "localhost";
SmtpMail.Send(msg);

但我得到的错误：

命令的次序错误。服务器响应为：尝试发送到非本地电子邮件地址时，该邮件服务器需要身份验证。请检查您的邮件客户端设置或与管理员联系以验证该域或地址为该服务器定义的。

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.

推荐答案

我用这个code。

 msg.Body = "Body";

 string smtpServer = "mail.DomainName";
 string userName = "[e-mail]";
 string password = "MyPassword";
 int cdoBasic = 1;
 int cdoSendUsingPort = 2;
 if (userName.Length > 0)
  {
    msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserver", smtpServer);
    msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 25);
    msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing", cdoSendUsingPort);
    msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", cdoBasic);
    msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", userName);
    msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", password);
    }
    msg.To = user.Email;
    msg.From = "[e-mail]";
    msg.Subject = "Subject";
    msg.BodyEncoding = System.Text.Encoding.UTF8;
    SmtpMail.SmtpServer = smtpServer;
   SmtpMail.Send(msg);
