为什么我不能从本地和服务器两边发送邮件 [英] Why i can't send mail from local and server both side

问题描述

我使用此代码发送邮件，

  var  smtp =  new  System.Net.Mail.SmtpClient（）; 
 {
  //   smtp.Host =smtp.gmail.com;  
  //   smtp.Port = 587;  
  //   smtp.EnableSsl = true;  
 
 smtp.Host =   localhost; 
 smtp.Port =  25 ; 
 smtp.EnableSsl =  false ; 
 
 smtp.UseDefaultCredentials =  false ; 
 smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
 smtp.Credentials =  new  NetworkCredential（fromMail.ToString（），  2345664\" ）; 
 smtp.Timeout =  20000 ; 
 
} 
 smtp.Send（Msg）; 
 reader.Dispose（）; 

使用此方法我无法从本地和服务器端发送邮件。

i得到了这个错误 - 当我在localhost上运行我的代码时



由于目标机器主动拒绝它，因此无法建立连接127.0.0.1 ：25



但我也可以从服务器端发送邮件。



谁能告诉我原因为此，并为此提供解决方案。？

希望这些对你有用...

非常感谢你提供解决方案，



现在我用这个发送邮件的代码，

  protected   void  getDataforemail（ int  invitationID）
 {
 
  try  
 {
 EventManagerDataContext db =  new  EventManagerDataContext（）; 
 
 {
  var  q =（来自 a   db.EMR_EVENTs 
  join  b   a.ClientID上的db.EMR_CLIENTs等于b.ClientID 
  join  c   db.EMR_INVITATIONs on a.EventID等于c.EventID 
 
 其中 c.InvitationID == invitationID 
 
 选择  new  
 {
 EventID = a.EventID，
 Client_Name = b.Name，
 Event_Name = a.Name，
 Activation_Code = c.Activation_Code 
 
}）; 
 
  var  ev = q.FirstOrDefault（）; 
 
 StreamReader reader =  new  StreamReader（Server.MapPath（ 〜/ HTMLPage1.htm））; 
  string  readFile = reader.ReadToEnd（）; 
  string  myString =  ; 
 myString = readFile; 
 
 
 
 MailAddress fromMail =  new  MailAddress（  [e-mail]）; 
 
 Msg.CC.Add（ new  MailAddress（clientEmail（getClientId（lblclientname.Text））））; 
 
 
 myString = myString.Replace（  

CLIENT_NAME

I use this code for send mail ,

var smtp = new System.Net.Mail.SmtpClient();
                    {
                        //smtp.Host = "smtp.gmail.com";
                        //smtp.Port = 587;
                        //smtp.EnableSsl = true;

                        smtp.Host = "localhost";
                        smtp.Port = 25;
                        smtp.EnableSsl = false;
                        
                        smtp.UseDefaultCredentials = false;
                        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                        smtp.Credentials = new NetworkCredential(fromMail.ToString(), "2345664");
                        smtp.Timeout = 20000;

                    }
                    smtp.Send(Msg);
                    reader.Dispose();

using this method i can't send mail,from both local and server side.
i got this error -when i run my code on localhost

No connection could be made because the target machine actively refused it 127.0.0.1:25

but i also enable to send mail from server side.

can anyone tell me reason for that,and give solution for that.?

Thanks a lot for giving solution,

now i use this code for sending mail,

protected void getDataforemail(int invitationID)
      {

          try
          {
              EventManagerDataContext db = new EventManagerDataContext();

              {
                  var q = (from a in db.EMR_EVENTs
                           join b in db.EMR_CLIENTs on a.ClientID equals b.ClientID
                           join c in db.EMR_INVITATIONs on a.EventID equals c.EventID

                           where c.InvitationID == invitationID

                           select new
                           {
                               EventID = a.EventID,
                               Client_Name = b.Name,
                               Event_Name = a.Name,
                               Activation_Code = c.Activation_Code

                           });

                  var ev = q.FirstOrDefault();

                  StreamReader reader = new StreamReader(Server.MapPath("~/HTMLPage1.htm"));
                  string readFile = reader.ReadToEnd();
                  string myString = "";
                  myString = readFile;



                  MailAddress fromMail = new MailAddress("[e-mail]");

                  Msg.CC.Add(new MailAddress(clientEmail(getClientId(lblclientname.Text))));


                  myString = myString.Replace("
