发送gmail本地主机时出错 [英] error in send gmail localhost

问题描述

我想用localhost发送gmail
我的代码是这个

i want send gmail with localhost
and my code is this

////my message setting
         MailMessage msg = new MailMessage();
         msg.From = new MailAddress("[e-mail]");
         msg.To.Add("[e-mail]");
         msg.Body = "body my mail";
         msg.Subject = "my mail subject";
         //msg.IsBodyHtml = true;
         //msg.Priority = MailPriority.High;

         SmtpClient client = new SmtpClient();
         client.UseDefaultCredentials = false;
         client.Credentials = new NetworkCredential("[e-mail]", "pwd", "smtp.gmail.com");
         client.Host = "smtp.gmail.com";
         client.Port = 587;
         client.DeliveryMethod = SmtpDeliveryMethod.Network;
         client.EnableSsl = true;


         client.Send(msg);

错误是:
SMTP服务器需要安全连接，或者客户端未通过身份验证.服务器响应为:5.5.1需要身份验证.在
了解更多信息 smtp客户端的问题在哪里?

and error is:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at
where is problem in smtp client?

推荐答案

问题出在您的身份验证凭据之内. gmail服务器拒绝了您的请求，因为它无法识别凭据，因此您需要使用将被接受的用户ID和密码.我注意到您已经在此处 [ ^ ];尝试它们会发生什么?

[edit]
根据 gmail指南 [

The problem is within your authentication credentials. The gmail server is rejecting your request as it does not recognise the credentials so you need to use a user id and password that will be accepted. I notice that you have already been given some suggestions here[^]; what happens when you try them?

[edit]
According to the gmail guidelines[^], the SMTP server uses port 465 rather than 587 as you have coded.
[/edit]

[edit]
Further testing by me reveals that port 465 times out, but 587 works.

我转到控制面板----管理员工具--smtp设置
并设置我的凭据和....
并开始我的项目
但是也有这个问题



发送邮件失败

i go to controlpanel----administrator toools--smtp setting
and set my credential and ....
and start my project
but a have this problem too



Failure sending Mail

尝试此操作

try this

MailAddress mailfrom = new MailAddress ( "[e-mail]" );
           MailAddress mailto = new MailAddress ( "[e-mail]" );
           MailMessage newmsg = new MailMessage ( mailfrom, mailto );

           newmsg.Subject = "Subject of Email";
           newmsg.Body = "Body(message) of email";

           ////For File Attachment, more file can also be attached

           Attachment att = new Attachment ( "G:\\code.txt" );
           newmsg.Attachments.Add ( att );

           SmtpClient smtps = new SmtpClient ( "smtp.gmail.com", 587 );
           smtps.UseDefaultCredentials = false;
           smtps.Credentials = new NetworkCredential ( "[e-mail]", "pwd" );
           smtps.EnableSsl = true;
           smtps.Send ( newmsg );
