El post :

Código Delphi [-]
function TFEnviar1.sendMail(SMTP_Server:String; SMTP_Port:Integer; SMTP_AuthType:TIdSMTPAuthenticationType;
                  SMTP_UseTLS:TIdUseTLS; From_Mail, From_Name, From_Pass, To_List_Emails,
                  Mail_Subject:String; Body_Message:TMemo):String;
var
  IdMessage1: TIdMessage;
  IdSMTP1:TIdSMTP;
  IdSSLSocket: TIdSSLIOHandlerSocketOpenSSL;
  lista:TStringList;
  i:integer;
begin
  IdMessage1 := TIdMessage.Create(nil);
  IdSMTP1 := TIdSMTP.Create(nil);
  IdSSLSocket := TIdSSLIOHandlerSocketOpenSSL.Create(nil);

  //IdSSLSocket.OnStatusInfo := @OpenSSLStatusInfo;
  IdSMTP1.IOHandler := IdSSLSocket;
  idSMTP1.AuthType := SMTP_AuthType;
  idSMTP1.Host := SMTP_Server;
  idSMTP1.Port := SMTP_Port;
  idSMTP1.Username:= From_Mail;
  idSMTP1.Password:= From_Pass;
  idSMTP1.UseTLS := SMTP_UseTLS;
  IdMessage1.From.Text := From_Mail;
  IdMessage1.From.Name := From_Name;
  IdMessage1.Recipients.EMailAddresses := To_List_Emails;
  IdMessage1.Subject := UTF8ToAnsi(Mail_Subject);
  lista:= TStringList.Create;
  for i:=0 to Body_Message.lines.count-1 do
      lista.Add(Body_Message.lines[i]);

  IdMessage1.Body.Clear;
  IdMessage1.Body.Text := lista.Text;
  //CargaMensajeMail(From_Mail,To_List_Emails,UTF8ToAnsi(Mail_Subject),lista);
  try
      idSMTP1.Connect;
      application.processmessages;
      IdSMTP1.Send(IdMessage1);
  except
      on E: Exception do
        ShowMessage('Failed: ' + E.Message);
  end;
    idSMTP1.Disconnect();
    IdMessage1.Free;
    IdSMTP1.Free;
    IdSSLSocket.Free;
end;

Y los botones deben llamar a la función con los datos de nuestra cuenta de correo, para gmail es.

Código Delphi [-]

procedure TFEnviar1.BTNEnviarClick(Sender: TObject);

begin
    sendMail('smtp.gmail.com',587,satDefault,utUseExplicitTLS,'martin.artaza@gmail.com',
          Edeparte.text,'tuclave',edestino.Text,easunto.text, Memo1);
end;

y para mandar un SMS es (para argentina):

Código Delphi [-]procedure TFEnviar1.Button1Click(Sender: TObject);
var direccion: string;
begin
direccion := earea.text + enumero.Text;
case cbCompania.ItemIndex of
  0: begin direccion := direccion + '@sms.ctimovil.com.ar'; end;
  1: begin direccion := direccion + '@sms.movistar.net.ar'; end;
  2: begin direccion := direccion + '@personal-net.com.ar'; end;
  end;
sendMail('smtp.gmail.com',587,satDefault,utUseExplicitTLS,'martin.artaza@gmail.com',
        Edeparte.text,'tuclave', direccion,easunto.text, Memo1);
end;

Queria saber si esta tecnica para mandar sms gratis sigue funcionando porque este codigo se hizo en el 2009 o 2010. ¿ Esta tecnica sigue funcionando o esta obsoleta ?
