使用smtp.gmail发送邮件会出现错误发送邮件失败.

问题描述

我正尝试在C#win应用中使用smtp.gmail发送邮件.它给了我错误

无法连接到远程服务器.
连接尝试失败，因为一段时间后连接方未正确响应，或者建立的连接失败，因为连接的主机未能响应74.125.127.109:587

以下代码可能有什么问题.任何帮助将不胜感激

i am trying to send mail using smtp.gmail in C# win app. it gives me error

Unable to connect to the remote server.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 74.125.127.109:587

What could be wrong with following code. Any help would be greatly appreciated

System.Net.Mail.MailMessage MyMailMessage = new System.Net.Mail.MailMessage();
MyMailMessage.From = new System.Net.Mail.MailAddress("[email protected]");
MyMailMessage.To.Add("[email protected]");
MyMailMessage.Subject = "Feedback Form";
MyMailMessage.Body = "this is test";
System.Net.Mail.SmtpClient SMTPServer = new System.Net.Mail.SmtpClient("smtp.gmail.com");
SMTPServer.Port = 587;
SMTPServer.Credentials = new System.Net.NetworkCredential("[email protected]", "password");
SMTPServer.EnableSsl = true;
SMTPServer.Send(MyMailMessage);
