使用gmail进行Smtp C＃身份验证 [英] Smtp C# authentification using gmail

问题描述

这是我的代码：

here is my code:

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
                    message.To.Add("[e-mail]");
                    message.Subject = "Nici un Clinet valabil pentru reparare";
                    message.From = new System.Net.Mail.MailAddress("[e-mail]");
                    message.Body = "Nu mai sunt clienti la care mecanicii sa lucreze";
                    string sendEmailsFrom = "[e-mail]";
                    string sendEmailsFromPassword = "my_invisible_password";
                    System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);
                    smtp.EnableSsl = true;
                    smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                    smtp.Credentials = new NetworkCredential(sendEmailsFrom, sendEmailsFromPassword);
                    smtp.Timeout = 20000;
                    smtp.Send(message);

我的错误：

SMTP服务器要求安全连接或客户端未经过身份验证。服务器响应是：5.5.1需要验证。



有什么问题？我无法看到它，也无法在谷歌上找到解决方案。



谢谢，

我的尝试：



电子邮件

And my error:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

What is the problem? i can't see it and can't find a solution on google.

Thanks,

推荐答案

你需要设置

You need to set

UseDefaultCredentials = false;

首先和之后设置你想要使用的凭证

first and after that set the credentials you want to use

Credentials = new NetworkCredential("[e-mail]", "my_invisible_password");

另外确保您可以使用mail.google.com页面上的用户名和密码登录。



祝你好运，

Also make sure you can login from with your username and password from the mail.google.com page.

Good luck,
OI

另请注意，当您进行大量连接时，谷歌会阻止您登录n次尝试。



我总是使用本地电子邮件服务器进行开发： http：// www.hmailserver.com/ [ ^ ]

它是免费的。您只需配置它并在您的计算机上运行它，连接到localhost：2525。

请务必关闭此禁令选项（自动禁止）。

Also please be aware that google will block you from logging in when you do to much connection attempts.

I always use a local email server for development: http://www.hmailserver.com/[^]
It's free. You can simply configure it and run it on your computer, connecting to localhost:2525.
Please be sure to also turn down the ban-option ("auto-ban") of this one.

Goto Account of Gmail , then select Connected apps & sites Allow less secure apps: ON(if this is off you cannot send mails through apps,or your websites )
