Send email by using codeigniter library via localhost

Please check my working code.

function sendMail(){    $config = Array(  'protocol' => 'smtp',  'smtp_host' => 'ssl://smtp.googlemail.com',  'smtp_port' => 465,  'smtp_user' => 'xxx@gmail.com', // change it to yours  'smtp_pass' => 'xxx', // change it to yours  'mailtype' => 'html',  'charset' => 'iso-8859-1',  'wordwrap' => TRUE);        $message = '';        $this->load->library('email', $config);      $this->email->set_newline("\r\n");      $this->email->from('xxx@gmail.com'); // change it to yours      $this->email->to('xxx@gmail.com');// change it to yours      $this->email->subject('Resume from JobsBuddy for your Job posting');      $this->email->message($message);      if($this->email->send())     {      echo 'Email sent.';     }     else    {     show_error($this->email->print_debugger());    }}

I had the same problem and I solved by using the postcast server. You can install it locally and use it.

$insert = $this->db->insert('email_notification', $data);                $this->session->set_flashdata("msg", "<div class='alert alert-success'> Cafe has been added Successfully.</div>");                //require ("plugins/mailer/PHPMailerAutoload.php");                $mail = new PHPMailer;                $mail->SMTPOptions = array(                    'ssl' => array(                    'verify_peer' => false,                    'verify_peer_name' => false,                    'allow_self_signed' => true,                ),                );                $message="                     Your Account Has beed created successfully by Admin:                    Username: ".$this->input->post('username')." <br><br>                    Email: ".$this->input->post('sender_email')." <br><br>                    Regargs<br>                    <div class='background-color:#666;color:#fff;padding:6px;                    text-align:center;'>                         Bookly Admin.                    </div>                ";                $mail->isSMTP(); // Set mailer to use SMTP                $mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers                $mail->SMTPAuth = true;                 $subject = "Hello  ".$this->input->post('username');                $mail->SMTDebug=2;                $email = $this->input->post('sender_email'); //this email is user email                $from_label = "Account Creation";                $mail->Username = 'your email'; // SMTP username                $mail->Password = 'password'; // SMTP password                $mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted                $mail->Port = 465;                $mail->setFrom($from_label);                $mail->addAddress($email, 'Bookly Admin');                $mail->isHTML(true);                $mail->Subject = $subject;                $mail->Body = $message;                $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';             if($mail->send()){                  }
