      Those items are added automatically by your IMAP/POP server
      software, not postfix.

      If you're using different IMAP/POP software on the new box, it
      may not need those headers, or maybe it hasn't opened those
      mailboxes yet.

      At any rate, neither you nor postfix should ever add those
