You need to provide more details about WHAT doesn't work and WHAT errors you encounter — Jakub Konecki, Jun 24 '13 at 08:10

I think Gmail SMTP port should be 465, not 587.

I use 587 successfully, but it is Google... var client = new SmtpClient("smtp.gmail.com", 587) { Credentials = new NetworkCredential("acct@gmail.com", "pw"), EnableSsl = true }; – smoore4 Jun 24 '13 at 08:28
Log in to your account and check Sent folder. It the `smtp.Send` method doesn't throw an exception it means that the connection is correct. – Jakub Konecki Jun 24 '13 at 09:13

Have you tried commenting on that article / contact the author?

I guess there are 2 things here:

A. You haven't done anything in catch block. You should consider following in catch block

catch(Exception ex){
DisplayMessage.Text = ex.Message;
DisplayMessage.Visible = true;
}

B. check if the gmail account you are using has smtp with pop3/imap enabled.

try this

    protected void SendMail()
    {
        // any address where the email will be sending
        var toAddress = YourEmail.Text.ToString();
        //Password of your gmail address
        const string fromPassword = "Password";
        // Passing the values and make a email formate to display
        string subject = YourSubject.Text.ToString();
        string body = "From: " + YourName.Text + "\n";
        body += "Email: " + YourEmail.Text + "\n";
        body += "Subject: " + YourSubject.Text + "\n";
        body += "Question: \n" + Comments.Text + "\n";

        SmtpClient smtpClient = new SmtpClient();
        MailMessage message = new MailMessage();
        MailAddress fromAddress = new MailAddress("ml27.santos@gmail.com");
        smtpClient.Host = "smtp.gmail.com";
        smtpClient.Port = 587;
        smtpClient.UseDefaultCredentials = false;
        smtpClient.EnableSsl = true;
        smtpClient.Credentials = new System.Net.NetworkCredential("ml27.santos@gmail.com", fromPassword);
        message.From = fromAddress;
        message.To.Add(toAddress);
        message.Subject = subject;
        message.Priority = MailPriority.High;
        message.Body = body;
        message.IsBodyHtml = true;
        smtpClient.Send(message);
    }
