[imp] Renaming folders and bad subscription

[Lancaster, David]

Hi all,

Using:
horde-2.2.1.tar.gz
imapproxy-1.0.tar.gz
imp-3.2.1.tar.gz
mysql-server-3.23.54a-11.i386.rpm
pear-1.0.1.tar.gz
php_accelerator-1.3.3r2_php-4.2.1_linux_i686-glibc2.1.3.tgz
turba-1.2.tar.gz
and Communigate 4.06 as the IMAP server.

Create a folder "ParentFolder" and create a child folder "ChildFolder".
Rename "ParentFolder" to "ParentFolder-03".
IMP correctly unsubscribes "ParentFolder" and subscribes "ParentFolder-03", but does not
unsubscribe "ParentFolder/ChildFolder" nor subscribe "ParentFolder-03/ChildFolder".
On top of that, IMP still displays "ParentFolder/ChildFolder" as a valid folder in the
folder dropdown, as well as shows "ParentFolder-03" as a seperate folder.

First question is, where does the problem lie?  Should the IMAP server (Communigate)
handle the subscription changes during a rename, or is that the responsibility of the
client?  Outlook handles the renames itself, so is this an IMP issue?

Thanks,
David
