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

MyMailMessage.From = new System.Net.Mail.MailAddress("username@gmail.com");
MyMailMessage.To.Add("username@gmail.com");
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("username@gmail.com", "password");
SMTPServer.EnableSsl = true;
SMTPServer.Send(MyMailMessage);

Specifying a port in a .NET medium trust environment usually ends up in a security exception, and IIRC, you can use port 25 with Gmail -- even with EnableSsl set to true.

Hi,

The problem is that in Credentials you are using username@gmail, here you should use only username :)

this code is working fine

MailMessage mail = new MailMessage();
               SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
               mail.From = new MailAddress("xyz@gmail.com");
               mail.To.Add("abc@gmail.com");
               mail.Subject = "Test Mail";
               mail.Body = "test mail";
               SmtpServer.Port = 587;
               SmtpServer.Credentials = new System.Net.NetworkCredential("abc", "password");
               SmtpServer.EnableSsl = true;
               SmtpServer.Send(mail);
              Response.Write("mail Send");
