title: Gmail uses original "TO" address instead of "FROM" address for reply
body: <p>Using <a href="http://codeigniter.com/user_guide/libraries/email.html" rel="nofollow noreferrer">CI's email library</a>, I have the following code to send a pw to a user:</p>
  
  <pre><code>$email_html_message         =   '&lt;html&gt;&lt;body&gt;'.
                                          'Your password is '.$password.'&lt;br&gt;'.
                                          '&lt;a href="'.  base_url().'"&gt;Login to MySite&lt;/a&gt;'.
                                          '&lt;/body&gt;&lt;/html&gt;';
  
  
          $config['charset']  =   'iso-8859-1';
          $config['mailtype'] =   'html';
          $this-&gt;email-&gt;initialize($config);
  
          $this-&gt;email-&gt;from('ray@MySite.com', 'MySite Admin');
          $this-&gt;email-&gt;to($user_email);
          $this-&gt;email-&gt;subject('Your MySite Login');
          $this-&gt;email-&gt;message($email_html_message);
          $this-&gt;email-&gt;send();
  </code></pre>
  
  <p>I tested this code on two accounts:  Gmail and my ISP's smtp email account. </p>
  
  <p>Both tests sent an email, but here's the problem:</p>
  
  <p>If I click reply through gmail, the Reply TO address is the address the e-mail was sent to:</p>
  
  <p><img src="https://i.stack.imgur.com/gtrsn.jpg" alt="enter image description here"></p>
  
  <p>This does not happen when I click reply through Windows Mail (e.g. my smtp account).</p>
  
  <p>Here is the "original message" with headers from gmail:</p>
