 From config/servers.php:

  *           NOTE: Due to limitations within PHP, IMP can only support auto-
  *                 detection of namespace parameters with IMAP TLS connections
  *                 (e.g 'imap/tls') if using PHP version 5.1.0 or greater.
  *                 If using a version of PHP less than 5.1.0, the following
  *                 options are available:
  *                 1. RECOMMENDED - If a secure IMAP connection is needed, use
  *                    a direct connection to a SSL enabled IMAP port
  *                    (e.g. 'imap/ssl').
  *                 2. If you absolutely must use TLS, then it is REQUIRED to
  *                    define the 'namespace' parameter (see below).

Maybe you have 'namespace' defined and, thus, are working around this  
issue.  If not, there is no reason IMP should work since TLS requires  
stream_socket_enable_crypto(), which only appeared in PHP 5.1.
