Qt Messaging

[Lili Tagetes]

Hi! I'm writing one program for sending email. I saw some examples and took next code from one

QMessageService service;
     bool b;
 
 
    QString accountName("111@gmail.com");
    QMessage message;
    message.setType(QMessage::Email);
    message.setParentAccountId(QMessageAccountId(accountName));
 
    QString to("222@gmail.com");
    QMessageAddress addr(QMessageAddress::Email,to);
    message.setTo(addr);
 
    QString subject("first message");
    message.setSubject(subject);
 
    QString text("Hello");
    message.setBody(text);
 
   b = message.parentAccountId().isValid();
   if (service.send(message))
   {
       QMessageBox::information(0,tr("Success"),tr("Email sent successfully!"));
       hide();
   }
   else
   {
       QMessageBox::warning(0, tr("Failed"), tr("Unable to send message. Valid: %1").arg(b));
 
   }

QMessageService service;
     bool b;
 

    QString accountName("111@gmail.com");
    QMessage message;
    message.setType(QMessage::Email);
    message.setParentAccountId(QMessageAccountId(accountName));

    QString to("222@gmail.com");
    QMessageAddress addr(QMessageAddress::Email,to);
    message.setTo(addr);

    QString subject("first message");
    message.setSubject(subject);

    QString text("Hello");
    message.setBody(text);
  
   b = message.parentAccountId().isValid();
   if (service.send(message))
   {
       QMessageBox::information(0,tr("Success"),tr("Email sent successfully!"));
       hide();
   }
   else
   {
       QMessageBox::warning(0, tr("Failed"), tr("Unable to send message. Valid: %1").arg(b));

   }

To copy to clipboard, switch view to plain text mode 

When i try to send message on my device it all the times say me "Unable to send message.Valid: 1". I don't know where can be mistake...should you give me any ideas?
