    protected void BtnGonder_Click(object sender, EventArgs e)
    {
        string to = txtKime.Text;

        string from = txtEmail.Text;

        string password = txtPassword.Text;

        string subject = txtKonu.Text;

        string body = txtMesaj.Text;

        HttpPostedFile ektekidosya = fuAttach.PostedFile;

        try
        {
            MailGonder(to, from, password, subject, body, ektekidosya);
            Response.Write("Mail başarıyla gönderildi");
        }
        catch (Exception ex)
        {
            Response.Write("Mail gönderiminde hata oluştu. Err: " + ex.ToString());
        }
    }

我尝试了不同的端口，但没有任何帮助，我一直得到错误.Localserver工作正常，但服务器没有工作。我该如何解决这个错误？我尝试了一切..我的主机是1und1。
