Sending Email with Gmail's SMTP Using CodeIgniter's Email Library

This article aims to address a common issue encountered when sending emails using Gmail's SMTP server via CodeIgniter's email library:

Problem:

When using the original configuration (with SSL encryption and port 465), the following error occurs:

"fsockopen(): unable to connect to ssl://smtp.gmail.com:465 (Connection timed out)"

Solution 1:

Replace the original configuration with the enhanced one provided in the answer:

$config = Array(
    'protocol' => 'smtp',
    'smtp_host' => 'ssl://smtp.googlemail.com',
    'smtp_port' => 465,
    'smtp_user' => 'xxx',
    'smtp_pass' => 'xxx',
    'mailtype' => 'html', 
    'charset' => 'iso-8859-1'
);
$this->load->library('email', $config);
$this->email->set_newline("\r\n");

// Set to, from, message, etc.

$result = $this->email->send();

Solution 2 (Alternative):

Use a custom helper provided by a CodeIgniter user:

$this->load->helper('email');

$config = array(
    'protocol' => 'smtp',
    'smtp_host' => 'ssl://smtp.gmail.com',
    'smtp_port' => 465,
    'smtp_user' => 'xxx',
    'smtp_pass' => 'xxx',
    ' mailtype ' => 'html',
    'charset'  => 'iso-8859-1'
);

send_email('toemail@example.com', 'Email Subject', 'Email Body', $config);
