Indy 10 smtp authenticate抛出访问冲突

Question

我最近使用Delphi 5和Indy 10从fulgan下载。 当提供的凭据不正确时，会发生访问冲突错误。验证函数似乎产生错误。  也无法通过访问冲突错误，导致程序在没有任何警告的情况下关闭。 这是一个示例代码：

procedure TForm1.Button2Click(Sender: TObject);
var IDSMTP1: TIdSMTP;
 Idmessage1: TIDMessage;
IdSSLIOHandlerSocketOpenSSL1: TIdSSLIOHandlerSocketOpenSSL;
begin
  IDSMTP1 := TIdSMTP.Create;
  IdSSLIOHandlerSocketOpenSSL1 := TIdSSLIOHandlerSocketOpenSSL.Create;
  try
    with IDSMTP1 do begin
      Host := 'smtp.gmail.com';
      Port := 465;
      Username := 'email@gmail.com';
      Password := 'password';
      AuthType := satDefault;

      IdSSLIOHandlerSocketOpenSSL1.SSLOptions.SSLVersions := [sslvTLSv1];
      IOHandler := IdSSLIOHandlerSocketOpenSSL1;

      UseTLS := utUseRequireTLS;
    end;

    Idmessage1 := TIDMessage.Create;
    try
      with Idmessage1 do begin
        Subject := 'test';
        From.Address := 'email@gmail.com';
        From.Name := 'testname';
        Recipients.EMailAddresses := 'email@gmail.com';
      end;

      with IDSMTP1 do begin
        if not Connected then
          Connect;
        try  
          Authenticate;
          Send(IdMessage1);
        except
        end;
        Disconnect;
      end;

    finally
      Idmessage1.Free;
    end;
  finally
    IDSMTP1.Free;
    IdSSLIOHandlerSocketOpenSSL1.Free;
  end;
end;

提前谢谢。
