Mail

i m having enquiry form in my website.
after clicking the submit button the mail goes to the correct mail address but the in 'from' tag its showing the same email address as that of the destination mail address
thus 'to' and 'from' has the same email address inspite of the different address filled in the form.

the code of the button_click() is as below:
protected void btnSend_Click(object sender, EventArgs e)
{
MailMessage msg = new MailMessage();

msg.To.Add(new MailAddress("abc@xyz.com"));

msg.From = new MailAddress(txtEmail.Text);

msg.Subject = txtSubject.Text;

msg.Body = txtName.Text + Environment.NewLine + txtMessage.Value;

SmtpClient client = new SmtpClient();

client.Host = "smtp.xyz.com";//Place your smtp server in quotation marks (i.e. "smtp.live.com")

client.Port = 587;// Place your smtp port here, i.e. hotmail's smtp port is 587

client.Credentials = new NetworkCredential("username","password");

client.EnableSsl = true;

client.Send(msg);


}


plz help to resolve.
