Unable to connect the remove server

Code:

MailMessage mail = new MailMessage(sendd, receivee);
SmtpClient client = new SmtpClient();
client.Port = 587;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("xxxxxx@gmail.com", "yyyyyyy");
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);

Anyone help to find out what mistake i did?

Answer 1

can you try make your code to something like the following

 var smptClient = new SmtpClient("smtp.gmail.com", 587)
 {
     Credentials = new NetworkCredential("smit123@gmail.com", "123456789"),
     EnableSsl = true
 };
  smptClient.Send("smit123@gmail.com", "test@gmail.com", "Testing Email", "testing the email");

This code is properly tested with my own account on the Network..

Answer 2

Following code works for me

var client = new SmtpClient("smtp.gmail.com", 587)
{
    Credentials = new NetworkCredential("xxxxxx@gmail.com", "yyyyyyy"),
    EnableSsl = true
};
client.Send("myusername@gmail.com", "myusername@gmail.com", "this is a test email.", "this is my test email body");

which is pretty much the same as yours with the difference that it doesn't use MailMessage object. This might not be the problem, but you could give it a try.

I would also check if you have port 587 enable on your server
