title: line-height for paragraph spacing not working in Yahoo Mail
body: <p>For some reason, line spacing is not working for separating paragraphs, when sending e-mails with this code to my yahoo mail account, or any yahoo mail account.  How can I fix this?</p>
  
  <p>Here's what I'm using, but isn't working:</p>
  
  <pre><code>&lt;p style="line-height:150%"&gt;
  &lt;span style="font-family:Helvetica, Arial, sans-serif; font-size:10.5pt; line-height:150%; color:#333333; margin-bottom: 1em;"&gt;Caro [Membro],&lt;/span&gt;
  &lt;/p&gt;
  &lt;p style="line-height:150%"&gt;
  &lt;span style="font-family:Helvetica, Arial, sans-serif; font-size:10.5pt; line-height:150%; color:#333333; margin-bottom: 1em;"&gt;Estou escrevendo com uma atualização importante para os membros de N sobre o Programa de Garantia de Obrigações CDFI.&lt;/span&gt;
  &lt;/p&gt;
  </code></pre>
  
  <p>Looks like this:</p>

  <p>How do I fix this?  Hell, I even put a margin-bottom on it, and that doesn't even seem to work!</p>
