使用asp.net从Web服务器发送邮件？不适用于Godaddy网络服务器

Question

我有一个网站，有一个Contact Us标签。用户必须填写表格，点击按钮我应该收到用户的邮件。

当我从localhost运行时，它工作正常。但是相同的代码并没有在Godaddy网络服务器中运行。这是我的代码

try
        {
            MailMessage mailMessage = new MailMessage("From@gmail.com", "To@mydomain.com");
            mailMessage.Subject = txtSubject.Text;

            string msg = "#Sender Name: " + txtUserName.Text + "#Sender Email ID: " + txtUserEmailId.Text + "#Company Name: " + txtCompanyName.Text + "#Mobile No: " + txtMobileNo.Text + "#Office Telephone No: " + txtOfficeTelephoneNo.Text + "#Office Fax No: " + txtOfficeFaxNo.Text + "#City: " + txtCity.Text + "#Sender Message: " + txtMessage.Text;
            string newMsg = msg.Replace("#", "\n");
            mailMessage.Body = newMsg;

            SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);

            smtpClient.Credentials = new System.Net.NetworkCredential()
            {
                UserName = "From@gmail.com",
                Password = "Password"
            };

            smtpClient.EnableSsl = true;
            smtpClient.Send(mailMessage);
        }
        catch (Exception ee)
        {
            Response.Write(ee.Message);
        }
