This Code works
// Create the msg object to be sent
MailMessage msg = new MailMessage();
// Add your email address to the recipients
msg.To.Add("mr@soundout.net");
// Configure the address we are sending the mail from
MailAddress address = new MailAddress("mr@soundout.net");
msg.From = address;
msg.Subject = txtSubject.Text;
msg.Body = txtName.Text + "n" + txtEmail.Text + "n" + txtMessage.Text;
SmtpClient client = new SmtpClient();
client.Host = "relay-hosting.secureserver.net";
client.Port = 25;
// Send the msg
client.Send(msg);
