title: Get encrypted string when FETCH mail from IMAP
body: <p>I'm trying to write a IMAP mail client on C#.net with TCPClient and SSL. I can get past the connection and authentication just fine but when I fetch mail from imap.google.com, it return a encrypted string that I can't read at all. Something like:</p>
  
  <pre><code>Subject: =?UTF-8?B?UmU6IDMw5pyf5a6f57+S55Sf44Gu5oOF5aCx44Gr6Zai44GX44Gm?=
  </code></pre>
  
  <p>My FETCH commands are as below</p>
  
  <pre><code>"$ FETCH " + number + " body[header]\r\n"
  "$ FETCH " + number + " body[text]\r\n"
  </code></pre>
  
  <p>What do I have to do to get the header and body of the mail to display correctly?</p>
