从谷歌发送电子邮件在生产服务器上失败但从localhost可以正常工作

Question

这是控制器中的代码:

[HttpPost, ValidateInput(true)]
        public ActionResult Contact(ContactForm model)
        {
            if (!ModelState.IsValid)
            {
                return Json("error");

            }
            else
            {

                WebMail.SmtpServer = "smtp.gmail.com";
                WebMail.UserName = //email here
                WebMail.Password = //password here
                WebMail.EnableSsl = true;

                string message = model.Name + " " + model.Telephone + " " + model.Email + " " + model.Address + " " + model.City + " " + model.ZipCode;

                try
                {
                    WebMail.Send("example@example.com", "philaslim.com/info email", message, model.Email);
                    return Json("thanks");
                }
                catch (Exception ex)
                {
                    return Json(ex.Message.ToString());
                }

            }

正如我所说,它只在生产服务器上失败.返回的异常消息是"发送邮件失败".有任何想法吗？

编辑:InnerException:

Answer 1

您的外发SMTP端口(25,587)可能已在服务器上关闭,请检查防火墙设置.
