Send mail via MailGun in CakePHP

i run a cloud app (using CakePHP) on Rackspace and i wanna send emails using cakephp. I used this: https://github.com/kochb/cakephp-mailgun but it returns me an

 "Could not send email.

Error: An Internal Error Has Occurred." 

error. The way i try to send an email is with the following code:

$Email = new CakeEmail();


          $from = $this->request->data['Mail']['from'];
          $to = ($this->request->data['Mail']['to']);
          $subject = $this->request->data['Mail']['subject'];
          $message = $this->request->data['Mail']['message'];

                $Email->sender($from, 'TestName');
                $Email->from($from)
                    ->bcc($to)  
                    ->replyTo($from)
                    ->subject($subject)
                    ->send($message);



                    $this->Session->setFlash('On the way to recipient');
                    $this->redirect(array('action' => 'index'));

I have edited the Config/Email.php file inserting the MailGun API credentials etc.

What's possibly going on? Can you find out why this happens?

Thanks in advance!

(I was having the same errors you were)

The BasicTransport didn't have the right "pre-processing" nor the appropriate response handling.

I copied over the functionality from CurlTransport and it works for me now.

Specifically, we needed:

    $post = array();
    $post_preprocess = array_merge(
        $email->getHeaders(array('from', 'sender', 'replyTo', 'readReceipt', 'returnPath', 'to', 'cc', 'bcc', 'subject')),
        array(
            'text' => $email->message(CakeEmail::MESSAGE_TEXT),
            'html' => $email->message(CakeEmail::MESSAGE_HTML)
        )
    );
    foreach ($post_preprocess as $k => $v) {
        if (! empty($v)) {
            $post[strtolower($k)] = $v;
        }
    }

and then:

    $response = $http->post($url, $post, $request);
    if ($response === false) {
        throw new SocketException("Mailgun BasicTransport error, no response", 500);
    }

    $http_status = $response->code;
    if ($http_status != 200) {
        throw new SocketException("Mailgun request failed.  Status: $http_status, Response: {$response->body}", 500);
    }
