Not able to send email via a windows application

[EDN Admin]

Hi,
I am trying to make an application to send email. It actually throws an error stating SmtpException was unhandled, Failure sending email.
error code: 10060
My code is as follows:

namespace SendMail
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnSendMail_Click(object sender, EventArgs e)
{
MailMessage mail = new MailMessage();
mail.To.Add(txtBoxMailID.Text);
mail.From = new MailAddress("anshumansingh@gmail.com", "Anshuman Singh");
mail.Body = "Hi, This mail is from my application n -- Anshu";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential("anshumansingh", "mypass");
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = true;
Attachment attachment = new Attachment(@"G:Mail.txt");
mail.Attachments.Add(attachment);
smtp.Send(mail);
MessageBox.Show("Hurray!! n Mail Sent");
}
}
}


Error Details:
Message:
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 72.14.213.109:587

Stack Trace:

Any help will be great.

Thanks,
