Question

我有以下C＃代码从Web应用程序发送邮件，但只有当我在visual studio中本地运行时它才能工作和发送邮件，当我将网站托管到服务器时它不会发送邮件。这是代码：

var fromAddress = ConfigurationManager.AppSettings["fromAddress"];
var toAddress = ConfigurationManager.AppSettings["toAddress"];

string fromPassword = ConfigurationManager.AppSettings["fromPassword"];

MailMessage msg= new MailMessage();
SmtpClient smtp = new SmtpClient();
try
{
  msg.To.Add(toAddress);
  msg.Body = "From: " + TextBox2.Text + "\n"
    + "Name: " + TextBox1.Text + "\n"
      + "Message: " + TextBox3.Text + "\n";
  msg.Subject = "Aztech Website Contact Form";
  msg.From = new MailAddress(toAddress);

  smtp.Host = "smtp.gmail.com";
  smtp.Port = 587;
  smtp.EnableSsl = true;
  smtp.UseDefaultCredentials = false;
  smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
  smtp.Timeout = 300000;
  smtp.Send(msg);
  Page.ClientScript.RegisterStartupScript(GetType(), "msgbox", "showAlert();", true);
}
catch (Exception ex)
{
  Label1.Text = ex.Message;
  Label1.Visible = true;
}

请在将其托管到服务器后，建议如何在Web应用程序上使用此邮件功能。服务器中的IIS管理器是否需要进行任何更改？
