title: Emails are put into spam - wrong headers problem
body: <p>this is my first question on StackOverflow, but I think that we'll both come to the happy end. :) The problem is: I've got newsletter script written in PHP and when I send those emails to the various accounts they are put in the spam folder. Here is what I get in mail headers:</p>
  
  <pre><code>X-Spam-status: Yes, score=5.01 tagged_above=1 required=4.5 
  tests=[HTML_FONT_SIZE_LARGE=0.001, HTML_MESSAGE=0.001, 
  HTML_TAG_BALANCE_BODY=0.712, MIME_HTML_ONLY=1.105, MISSING_DATE=1.396, 
  MISSING_MID=0.14, RCVD_IN_BRBL_LASTEXT=1.644,TO_EQ_FM_DOM_HTML_ONLY=0.001, 
  T_FRT_CONTACT=0.01] autolearn=no
  </code></pre>
  
  <p>And here are my questions:</p>
  
  <ol>
  <li>What is that and how to fix status <code>RCVD_IN_BRBL_LASTEXT</code>? I haven't found anything informative googling that phrase.</li>
  <li><p>How to fix MISSING_DATE status? I've put in the code generating whole email:</p>
  
  <p><code>$mailHeaders[] = "Date: ".date('Y-m-d H:i:s', time());</code></p></li>
  </ol>
  
  <p>but with no success. "Date" fields comes only as <code>H:i</code> (13:45, for example) - Thunderbird 3.1.3 FYI. Searching on SO didn't help me. I have also tried adding <code>Delivery-Date</code> status - still nothing.</p>
