Retrieving Message-Id using CakeEmail on Amazon SES via SMTP

I'm using CakePHP 2.6 and using CakeEmail to send a verification email to users.

$Email = new CakeEmail('smtp');
                $Email->to($this->request->data['Account']['account_email']);
                $Email->subject('Verify your account before you continue');
                $Email->send('http://localhost/Accounts/verify/'.$this->request->data['Account']['account_verificationhash']);

As Amazon SES rewrites the message-id, I cannot attribute complaints and bounces to a specific email message. According to their docs, Amazon SES returns the message ID in the final SMTP response. I.e.(250 Ok <Message ID>)

How can I retrieve that response code?
