title: Amazon SES error: Missing required header 'To'
body: <p>I'm new in Amazon SES and I'm trying to send an email with this code:</p>
  
  <pre><code>&lt;?php
      require_once 'aws/sdk.class.php';
  
      $ses = new AmazonSES();
      $to = array('ToAddress' =&gt; 'mario@wowfi.com');
      $content = array('Subject.Data' =&gt; 'Tema', 'Body.Text.Data' =&gt; 'hello');
      $r = $ses-&gt;send_email("mario@wowfi.com", $to , $content);
      print_r($r);
  ?&gt;
  </code></pre>
  
  <p>In the output it says: Missing required header 'To', what am I doing wrong? </p>
