title: CodeIgniter Ion Auth not sending activation email
body: <p>I have CodeIgniter Ion Auth configured with the following smtp info:</p>
  
  <pre><code>$config['use_ci_email'] = FALSE;
  $config['email_config'] = array(
      'mailtype' =&gt; 'html',
      'protocol' =&gt; 'smtp',
      'smtp_host' =&gt; 'mail.example.com',
      'smtp_user' =&gt; 'support@example.com', // actual values different
      'smtp_pass' =&gt; 'password',
      'smtp_port' =&gt; '26'
  );
  </code></pre>
  
  <p>When I register for an account, Ion Auth simply says "Activation email sent" but I see nothing in my inbox (checked spam folder too). I checked the info with a SMTP testing tool, and the SMTP info provided in <code>$config['email_config']</code> is correct. I followed the Ion Auth documentation, but I am not receiving any emails. Is there anything else that needs to be done? Thanks!</p>
