title: Alpine INBOX contains 0 messages
body: <p>I configured two collection lists in Alpine. In M S L.
  I entered a nickname and then a server in the following way:</p>
  
  <p><code>mail.server:993/ssl/user=username</code></p>
  
  <p>After entering the password all mails are displayed in INBOX including all subfolders. They can be edited, etc.
  After a while the INBOX is empty. Only the INBOX. All subfolders still work. The only thing that works is deleting and reading the collection list. Restarting Alpine doesn't work.</p>
  
  <p>This happens to both collection lists but not at the same time.</p>
  
  <p>Does anybody have an idea what this can be? </p>
  
  <p>Thanks in advance,
  Stefan</p>
