Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.

public function sendEnquiry() {
            $this->load->library('email');
            $name = $this->input->post("fname");
            $cemail = $this->input->post("email");
            $pno = $this->input->post("phone");
            $message = $this->input->post("message");
            $config['protocol']    = 'smtp';
            $config['smtp_host']    = 'ssl://mail.gatewaykhobar.com';
            $config['smtp_port']    = '465';
            $config['smtp_timeout'] = '7';
            $config['smtp_user']    = '***********';
            $config['smtp_pass']    = '***********';
            $config['charset']    = 'utf-8';
            $config['newline']    = "\r\n";
            $config['mailtype'] = 'text'; // or html
            $config['validation'] = FALSE;

            $this->email->initialize($config);
            $this->email->from('[email protected]','Gateway Restaurent Contact');
            $this->email->to($cemail); 
            $this->email->subject('Gateway Restaurent Contact Enquiry');

           $this->email->message($message);  
            $send = $this->email->send();
            if($send) {
                echo json_encode("send");
            } else {
                $error = $this->email->print_debugger(array('headers'));
                echo json_encode($error);
            }

        }

Answer 1

Change smtp_port from 465 to 587.

Make sure $config['newline'] = "\r\n"; is in double quotes not single quotes.

Answer 2

$mail_config['smtp_host'] = 'smtp.gmail.com';
$mail_config['smtp_port'] = '587';
$mail_config['smtp_user'] = '[email protected]';
$mail_config['_smtp_auth'] = TRUE;
$mail_config['smtp_pass'] = 'password';
$mail_config['smtp_crypto'] = 'tls';
$mail_config['protocol'] = 'smtp';
$mail_config['mailtype'] = 'html';
$mail_config['send_multipart'] = FALSE;
$mail_config['charset'] = 'utf-8';
$mail_config['wordwrap'] = TRUE;
$this->email->initialize($mail_config);

$this->email->set_newline("\r\n");

I just added the last line

Answer 3

A common cause of this is the way that CodeIgniter interacts with the SMTP server with regards to line breaks. Your SMTP server might require \r\n and CodeIgniter is using \n.

There is an easy fix: after your $this->email->initialize(), add the following:

$this->email->set_newline("\r\n");  

That should get it working for you.

Answer 4

Just use "mail" for the 'protocol' array item, and that's all...

$config = array();
        $config['useragent']    = $system_name;
        $config['mailpath']     = "/usr/bin/sendmail"; // or "/usr/sbin/sendmail"
        $config['protocol']     = "mail"; //use 'mail' instead of 'sendmail or smtp'
        $config['smtp_host']    = "your domain name";
        $config['smtp_user']    =  $from;
        $config['smtp_pass']    = "*************";
        $config['smtp_port']    =  465;
        $config['smtp_crypto']  = 'ssl';
        $config['smtp_timeout'] = "";
        $config['mailtype']     = "html";
        $config['charset']      = "utf-8";
        $config['newline']      = "\r\n";
        $config['wordwrap']     = TRUE;
        $config['validate']     = FALSE;
