c# - 从谷歌发送电子邮件在生产服务器上失败但在本地主机上工作正常

Question

Controller 中的代码如下:

[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。返回的异常信息是“发送邮件失败。”。有什么想法吗？

编辑:内部异常:

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: 连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败因为连接的主机未能在 System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) 在 System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& 地址、ConnectSocketState 状态、IAsyncResult asyncResult、Int32 超时、Exception& 异常)--- 内部异常堆栈跟踪结束 --- 在 System.Net.ServicePoint.GetConnection(PooledStream PooledStream、对象所有者、 bool 异步、IPAddress 和地址、Socket 和 abortSocket , Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(对象owningObject，GeneralAsyncDelegate asyncCallback)在System.Net.ConnectionPool.GetConnection(对象owningObject，GeneralAsyncDelegate asyncCallback，Int32 creationTimeout)在System.Net.Mail.SmtpConnection.GetConnection(ServicePoint servicePoint)在System.Net.Mail.SmtpTransport.GetConnection(ServicePoint) servicePoint) 在 System.Net.Mail.SmtpClient.GetConnection() 在 System.Net.Mail.SmtpClient.Send(MailMessage 消息)

您的传出 SMTP 端口 (25,587) 可能在您的服务器上已关闭，请检查您的防火墙设置。
