title: Mandrill - Rules overriding with blank html content
body: <p>I am very new to Mandrill and whilst trying to use the Rules Engine (via SMTP integration without using Headers, with the incoming email being text), I have configured an open rule that states:</p>
  
  <pre><code>if
  sender's email matches scott***@****.com
  then
  set template to TestTemplate using template block body
  </code></pre>
  
  <p>but instead of the incoming message being inserted into the body block, as per the following html that's in the TestTemplate</p>
  
  <pre><code>&lt;div mc:edit="header"&gt;
       &lt;h2&gt;Testing Testing&lt;/h2&gt;
  &lt;/div&gt;
  &lt;div mc:edit="**body**" style="color:#000000;"&gt;
        &lt;h2&gt;123 123&lt;/h2&gt;
  &lt;/div&gt;
  &lt;div mc:edit="footer"&gt;
       Company contact information will go here.
  &lt;/div&gt; 
  </code></pre>
  
  <p>The 123 123 is being overwritten with blank content i.e. not what's being passed in on the original email message</p>
  
  <p>Any ideas? </p>
