Description

[WADA:World Anti-bad-Duping Agency]

+++ This bug was initially created as a clone of Bug #813331 +++

IMAP STATUS command is not permitted for Mbox which is already selected at a cached connection.
LIST-STATUS extension support is needed to utilize STATUS responce to LIST command for already selected Mbox at a cached connection.

>   This document defines the LIST-STATUS IMAP capability.
If preference like mail.server.default.use_condstore / mail.server.server#.use_condstore is added to LIST-STATUS support, it's useful for bypassing both "server side bug due to LIST-STATUS" and "Tb side bug due to LIST-STATUS",

Because following is written in RFC 5258, CAPABILITY responce of LiST-STATUS and LIST-EXTENDED are independent.
