SmtpClient: A connection attempt failed because the connected party did not properly respond after a period of time

Question

While working with Email sending in C#.NET in visual studio 2008 i got the below error

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 74.125.53.108:25

But the same code was working fine in some other PC but when i am testing today it gives me error in Send() method... Also my network connection is good where i am testing the email code..

Below is my email code

MailMessage mail = new MailMessage(); mail.To.Add(to); mail.From = new MailAddress(from); mail.Subject = subject; mail.Body = body; mail.IsBodyHtml = true; SmtpClient smtp = new SmtpClient(); smtp.Host = "smtp.gmail.com"; smtp.Credentials = new System.Net.NetworkCredential("[email protected]",                                                             "MyPassword"); smtp.EnableSsl = true; smtp.Send(mail); 

What could be the reasons for such error..???

Answer 1

The following code works for me. Your code was giving me errors, I believe it was due to not setting the port to 587.

MailMessage mail = new MailMessage(); mail.To.Add(to); mail.From = new MailAddress(from); mail.Subject = subject; mail.Body = body; mail.IsBodyHtml = true; SmtpClient smtp = new SmtpClient("smtp.gmail.com",587); smtp.EnableSsl = true; smtp.UseDefaultCredentials = false; smtp.Credentials = new System.Net.NetworkCredential(address, password); smtp.Send(mail);
