i got same error...

Try using port 25.

As per my knowledge this is basically your firewall blocking the request to send. Please check with your network team.

Remove this line,
smtp.EnableSsl = true;

Okay, try this:

C#

string name ="name";
                    string password = "password";
                    string email_id = "email";

                    MailMessage mail = new MailMessage();
                    mail.From = new MailAddress("blah@gmail.com");
                    mail.To.Add(email);

                    mail.Subject = "Password Recovery ";
                    mail.Body = "Name : " + name +
                                "<br />Password : " + password +
                                "<br />Email : " + email_id;
                    mail.IsBodyHtml = true;

                    SmtpClient client = new SmtpClient();
                    client.Host = "smtp.gmail.com";
                    client.Port = 587;
                    client.EnableSsl = true;
                    client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                    client.Credentials = new System.Net.NetworkCredential("blah@gmail.com", "8888888888");
                    client.Timeout = 2000000;
                    client.Send(mail);
