title: php imap_open Gmail sent folder returns empty array
body: <p>So my code looks like this:</p>
  
  <pre><code>$mailbox = imap_open('{imap.gmail.com:993/imap/ssl}Sent Mail', env('MAIL_USERNAME'), env('MAIL_PASSWORD'));
  $mailsIds = imap_search($mailbox, 'ALL');
  </code></pre>
  
  <p>And I get <code>false</code>. I've tried changing "Sent Mail" to "[Google Mail]/Sent Mail", "Sent", "SENT MAIL" and "SENT", but I get <code>false</code> all the time, but there ARE emails in this folder. What am I doing wrong?</p>
