**IMP (4.1+) Hierarchical folder structure with Cyrus IMAP**
Since IMP 4.1+ the previous hierarchical folder structure - personal folders below INBOX, shared folders beside INBOX - has gone, because it is not the correct way - according to the RFCs.
This has been discussed in [http://bugs.horde.org/ticket/?id=3004 Ticket #3004] and [http://bugs.horde.org/ticket/?id=2422 Ticket #2422].
Because some people still would like to have the folders presented the old way, here are patches to enable this - still working with HEAD from 16. March 2006.
I am not familiar with php and making patch-files - every suggestion would help.
A configuration option - ['server']['dont_strip_namespace'] - will be added to imp/conf.xml (update your IMP configuration after patching !), imp/lib/IMAP/Tree.php and framework/IMAP/IMAP/Tree.php (bring installed framework up-to-date after patching !) will be patched.
##red|Use this at your own risk !##
it is working fine for me with Cyrus 2.3.3, PHP 4.4.2, Apache 1.3.34 and Horde HEAD
