    {
        Mail::send('mail.mailsample', ['content' => $str_content], function($message)
        {
            $message->to($arr_recepients);
            $message->from('abc.org', 'abc');
            $message->subject($str_subject);

        });
        if(Mail:: failures())
            return false;

You should pass the $arr_recepients to the callback-block

Mail::send('mail.mailsample', ['content' => $str_content], function($message) use ($arr_recepients, $str_subject)
{

      $message->from('abc.org', 'abc');
      $message->subject($str_subject);
});

    { //...
