Unable to send email from CodeIgniter - codeigniter

Question

I am using CodeIgniter v3.1.4.In my website i have a 'Contact Us' page whose email sending function is not working at all.The strangest thing is that the exact code is working perfectly in one of my another project while its not in this project.
$this->email->send()
The above line executes but it does not send any emails.Neither does it show any error messages.However, if 'from' address & 'to' address are the same like(info#mywebsite.org) then it does send mail to itself.When 'from' address is like (user#gmail.com) and 'to' address is like (info#mywebsite.org), it does not work.
The code that i am using to send email is:
$this->form_validation->set_rules('sender_name', 'Name', 'required');
$this->form_validation->set_rules('sender_email', 'Enter Email', 'required|valid_email');
$this->form_validation->set_rules('mail_subject', 'Subject', 'required');
$this->form_validation->set_rules('mail_message', 'Your Message', 'required');
if (isset($_POST) && !empty($_POST))
{
if ($this->form_validation->run() == TRUE)
{
$this->email->from($this->input->post('sender_email'), $this->input->post('sender_name'));
$this->email->to("info#mywebsite.org");
$this->email->subject($this->input->post('mail_subject'));
$this->email->message($this->input->post('mail_message'));
if($this->email->send()){
$this->session->set_flashdata('success', 'Thanks for writing to us.You would hear from us shortly.');
}
else
{
$this->session->set_flashdata('error', 'Your message could not be sent.');
}
}
}
I tried to implement other solutions here in StackOverflow, but none of them are working.Please help me.

First Check With static data
$this->load->library('email');
$this->email->from('your#example.com', 'Your Name');
$this->email->to('someone#example.com');
$this->email->subject('Email Test');
$this->email->message('Testing the email class.');
$this->email->send();
echo "<pre>status<br>"print_r($this->email->print_debugger());die;
