add_action( 'phpmailer_init', 'send_email_using_smtp' );
function bsend_email_using_smtp( $phpmailer ) {
$phpmailer->isSMTP();

$phpmailer->SMTPAuth = true;
$phpmailer->Port = 465;
$phpmailer->Username = '[email protected]';
$phpmailer->Password = 'your-email-account-password';
$phpmailer->SMTPSecure = 'ssl';
$phpmailer->From = 'name@example.com';
$phpmailer->FromName = 'Your company name';
}
