title: Spaming CakePHP email and how to check mail is read by User
body: <p>Using below code in CakePHP i am sending emails to my users.
  But why my emails are going in Spam folder and 
  Also i want to check that User read the mail or not.
  how it could be ?</p>
  
  <p>I have read on <a href="http://book.cakephp.org/2.0/en/core-utility-libraries/email.html" rel="nofollow">http://book.cakephp.org/2.0/en/core-utility-libraries/email.html</a></p>
  
  <p>There they say with "readReceipt" we can receive the receipt of read.</p>
  
  <pre><code>App::uses('CakeEmail', 'Network/Email');
  $Email = new CakeEmail();
  $Email-&gt;emailFormat('both');
  $Email-&gt;from(array($webAdminData['User']['email'] =&gt; $webAdminData['User']['first_name'].' '.$webAdminData['User']['last_name']));
  $Email-&gt;replyTo(Configure::read('Email.EmailSupport'),Configure::read('SITE_SETTINGS.Name'));
  $Email-&gt;sender(array($webAdminData['User']['email'] =&gt; $webAdminData['User'['first_name'].' '.$webAdminData['User']['last_name']));
  $Email-&gt;to($this-&gt;request-&gt;data['Message']['leadEmail']);
  $Email-&gt;subject($this-&gt;request-&gt;data['Message']['subject']);
  $Email-&gt;send($this-&gt;request-&gt;data['Message']['body']);                          
  $this-&gt;Session-&gt;setFlash('Message has been sent successfully', 'default', 'success');
