title: Does IMAP guarantee that servers send responses in order?
body: <p>I am implementing an IMAP client.</p>
  <p>I think IMAP servers MUST send responses in order but I failed to find any mention about it in the <a href="https://www.rfc-editor.org/rfc/rfc3501" rel="nofollow noreferrer">IMAP specification</a>.</p>
  <p>Is it guaranteed by the specification? Or do I need to prepare to accept unordered responses from IMAP server?</p>
