使用INDY 10 SMTP与Office365 [英] Using INDY 10 SMTP with Office365

问题描述

我不熟悉INDY SMTP组件。我想用INDY和Office 365发送邮件。这是一个很好的主题，帮助我很多：
但是我没有想到如何使用SASL。 Office365地址是smtp.office365.com，端口587和TLS。所以我添加了一个SMTP和一个OpenSSL-IOHandler到我的窗体并设置了属性。但是我没有工作，应用程序刚刚冻结。我需要知道如何使用SASL与Office365。

谢谢。

解决方案

Office365仅支持TLS端口587上的 LOGIN SASL。

以下代码对我有用我刚刚尝试（所有这些设置也可以在设计时设置）：

1. 设置 TIdSMTP.AuthType 属性为 satDefault ，它使用SMTP AUTH LOGIN 命令：

     var 
    idSMTP1：TIdSMTP; 
    begin 
    idSMTP1：= TIdSMTP.Create（nil）; 
    try 
    idSMTP1.IOHandler：= TIdSSLIOHandlerSocketOpenSSL.Create（idSMTP1）; 
    idSMTP1.UseTLS：= utUseExplicitTLS; 
    TIdSSLIOHandlerSocketOpenSSL（idSMTP1.IOHandler）.SSLOptions.Method：= sslvSSLv3; 
    
    idSMTP1.Host：='smtp.office365.com'; 
    idSMTP1.Port：= 587; 
    
    idSMTP1.AuthType：= satDefault; 
    idSMTP1.Username：= ...; 
    idSMTP1.Password：= ...; 
    
    try 
    idSMTP1.Connect; 
    try 
    idSMTP1.Authenticate; 
    finally 
    idSMTP1.Disconnect; 
   结束
    ShowMessage（'OK'）; 
   除了
   对于E：异常do 
    begin 
    ShowMessage（Format（'Failed！'＃13'[％s]％s'，[E.ClassName，E.Message ]））; 
   加注
   结束
   结束
    finally 
    idSMTP1.Free; 
   结束
     




2. 设置 TIdSMTP.AuthType 属性到 satSASL 并使用 TIdSASLLogin ，它使用相同的SMTP AUTH LOGIN 命令：

     var 
    idSMTP1：TIdSMTP; 
    idSASLLogin：TIdSASLLogin; 
    idUserPassProvider：TIdUserPassProvider; 
    begin 
    idSMTP1：= TIdSMTP.Create（nil）; 
    try 
    idSMTP1.IOHandler：= TIdSSLIOHandlerSocketOpenSSL.Create（idSMTP1）; 
    idSMTP1.UseTLS：= utUseExplicitTLS; 
    TIdSSLIOHandlerSocketOpenSSL（idSMTP1.IOHandler）.SSLOptions.Method：= sslvSSLv3; 
    
    idSMTP1.Host：='smtp.office365.com'; 
    idSMTP1.Port：= 587; 
    
    idSASLLogin：= TIdSASLLogin.Create（idSMTP1）; 
    idUserPassProvider：= TIdUserPassProvider.Create（idSASLLogin）; 
    
    idSASLLogin.UserPassProvider：= idUserPassProvider; 
    idUserPassProvider.Username：= ...; 
    idUserPassProvider.Password：= ...; 
    
    idSMTP1.AuthType：= satSASL; 
    idSMTP1.SASLMechanisms.Add.SASL：= idSASLLogin; 
    
    try 
    idSMTP1.Connect; 
    try 
    idSMTP1.Authenticate; 
    finally 
    idSMTP1.Disconnect; 
   结束
    ShowMessage（'OK'）; 
   除了
   对于E：异常do 
    begin 
    ShowMessage（Format（'Failed！'＃13'[％s]％s'，[E.ClassName，E.Message ]））; 
   加注
   结束
   结束
    finally 
    idSMTP1.Free; 
   结束
     

更新 Office365不再支持SSL v3，您必须现在使用TLS v1.x：

 （idSMTP1.IOHandler）.SSLOptions.Method： = sslvTLSv1; 
  

I'm not familar with the INDY SMTP component. I want to send a mail with INDY and Office 365. Here is a nice topic which helped me a lot: What do the SMTP Indy component security and authentication properties do? But I did not figured out how to use SASL. Office365 adress is smtp.office365.com with port 587 and TLS. So I added an SMTP and an OpenSSL-IOHandler to my form and setted the properties. But I didn't work, the app is just freezing. I need to know how to use SASL with Office365.

Thanks.

解决方案

Office365 only supports the LOGIN SASL on TLS port 587.

The following code works fine for me when I just tried it (all of these settings can also be set up at design-time as well):

1. setting the TIdSMTP.AuthType property to satDefault, which uses the SMTP AUTH LOGIN command:

   var
     idSMTP1: TIdSMTP;
   begin
     idSMTP1 := TIdSMTP.Create(nil);
     try
       idSMTP1.IOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(idSMTP1);
       idSMTP1.UseTLS := utUseExplicitTLS;
       TIdSSLIOHandlerSocketOpenSSL(idSMTP1.IOHandler).SSLOptions.Method := sslvSSLv3;
   
       idSMTP1.Host := 'smtp.office365.com';
       idSMTP1.Port := 587;
   
       idSMTP1.AuthType := satDefault;
       idSMTP1.Username := ...;
       idSMTP1.Password := ...;
   
       try
         idSMTP1.Connect;
         try
           idSMTP1.Authenticate;
         finally
           idSMTP1.Disconnect;
         end;
         ShowMessage('OK');
       except
         on E: Exception do
         begin
           ShowMessage(Format('Failed!'#13'[%s] %s', [E.ClassName, E.Message]));
           raise;
         end;
       end;
     finally
       idSMTP1.Free;
     end;
   

2. setting the TIdSMTP.AuthType property to satSASL and using TIdSASLLogin, which uses the same SMTP AUTH LOGIN command:

   var
     idSMTP1: TIdSMTP;
     idSASLLogin: TIdSASLLogin;
     idUserPassProvider: TIdUserPassProvider;
   begin
     idSMTP1 := TIdSMTP.Create(nil);
     try
       idSMTP1.IOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(idSMTP1);
       idSMTP1.UseTLS := utUseExplicitTLS;
       TIdSSLIOHandlerSocketOpenSSL(idSMTP1.IOHandler).SSLOptions.Method := sslvSSLv3;
   
       idSMTP1.Host := 'smtp.office365.com';
       idSMTP1.Port := 587;
   
       idSASLLogin := TIdSASLLogin.Create(idSMTP1);
       idUserPassProvider := TIdUserPassProvider.Create(idSASLLogin);
   
       idSASLLogin.UserPassProvider := idUserPassProvider;
       idUserPassProvider.Username := ...;
       idUserPassProvider.Password := ...;
   
       idSMTP1.AuthType := satSASL;
       idSMTP1.SASLMechanisms.Add.SASL := idSASLLogin;
   
       try
         idSMTP1.Connect;
         try
           idSMTP1.Authenticate;
         finally
           idSMTP1.Disconnect;
         end;
         ShowMessage('OK');
       except
         on E: Exception do
         begin
           ShowMessage(Format('Failed!'#13'[%s] %s', [E.ClassName, E.Message]));
           raise;
         end;
       end;
     finally
       idSMTP1.Free;
     end;
   

Update: Office365 no longer supports SSL v3, you must use TLS v1.x now:

(idSMTP1.IOHandler).SSLOptions.Method := sslvTLSv1;
