Problem using CodeIgniter to send emails through Gmail?

The error means you cannot connect the the SMTP address you've entered.

you should use: smtp.gmail.com

You could download a nice little sparks package by "Shawn McCool" that utilizes "Swift-Mailer".Check out his site for install instructions

Here is my configuration for sending out email's using a DRY approach(PHP 5.3.0 required!).

Config|--mailer[dot]php

$config['swift_email_server'] = 'ssl://smtp.googlemail.com';$config['swift_email_port'] = 465;$config['swift_email_username'] = '######';$config['swift_email_password'] = '######';

Libarary|--MY_Email

    class MY_Email extends CI_Email {    public function __construct(){        parent::__construct();    }    /**     * =========================================================================     * Parse's html email templates - initalised via swift-mailer     *      * @param mixed $data     * @param string $template     * @return html     *      * =========================================================================      */    public function send_mail($data, $template){        //Anonymous functions are available since PHP 5.3.0        $callback = function ($matches) use ($data){            return ( isset($data[$matches[1]]) )                ? $data[$matches[1]]                : $matches[0];        };        //Finds any matches in brackets [] and replaces them with data passed via callback        return preg_replace_callback(                '/\[(.*?)\]/',                 $callback,                 read_file(EMAIL_TEMPLATES . $template));    }}Email templates location defined in index.phpdefine('EMAIL_TEMPLATES', 'emailtemplates');

Controller|--MY_Controller

    class MY_Controller extends MX_Controller{        protected $user;        protected $swiftMailer = NULL;        public function __construct(){            parent::__construct();            $this->user =   ($this->session->userdata('uid'))                        ?    Member::find($this->session->userdata('uid')) : array();            $this->setup_profile();           $this->form_validation->set_error_delimiters('<p class="form-error">', '</p>');        }        public function setup_profile(){            $sections = array(            'config'  => FALSE,            'http_headers' => FALSE,            'queries'  =>  FALSE,            'memory_usage'  =>  FALSE            );            $this->output->set_profiler_sections($sections);            if(ENVIRONMENT === 'development'){                $this->output->enable_profiler(TRUE);            }        }    protected function prep_email($data, $template){            $message =             Swift_Message::newInstance('Type your heading here...')              ->setFrom($data['email_address'])              ->setTo(array($this->config->item('primary_email'), $data['email_address']))              ->setBody( $this->email->send_mail($data, $template))              ->setContentType('text/html');            return ( $this->swiftMailer->send($message) );     }}
