title: nodemailer - anchor tag not working
body: <p>Whenever I try to send an email with an anchor tag using nodemailer v1.10, there is a <code>3D</code> character mixed up in my email. I believe this is <code>%3D</code> which stands for <code>=</code> when decoded. I use gmail as the service for the SMTP transport.</p>
  
  <p>Here is the "html" value I use in nodemailer</p>
  
  <pre><code>var resetUrl = req.protocol + '://' + req.get('host') + ':' + req.app.get('port') + '/password/reset?token=' + encodeURIComponent(digest);
  options.html = 'To reset your password, click this &lt;a href="' + resetUrl + '"&gt;&lt;span&gt;link&lt;/span&gt;&lt;/a&gt;.&lt;br&gt;This is a &lt;b&gt;test&lt;/b&gt; email.'
  </code></pre>
  
  <p>Here's how it looks when I click "show original" from the email I received.</p>
  
  <pre><code>To reset your password, click this &lt;a href=3D"http://192.168.1.=
  109:3000:3000/password/reset?token=3DoU5J1vm4VTLl0Ru8SMI7x3YvF3Y%3D"&gt;&lt;span&gt;=
  link&lt;/span&gt;&lt;/a&gt;.&lt;br&gt;This is a &lt;b&gt;test&lt;/b&gt; email.
  </code></pre>
  
  <p>I also noticed that there are <code>=</code> at the end of each line. Is this normal for gmail? The email I receive does appear normal in gmail. The link has a blue font color and is underlined but it does not work when I click it. I tried it in yahoo mail too and the link didn't work also.</p>
