have you tried lsub "" *

list will list ALL folders, lsub will list only subscribed folders.
another thing to look at would be what DB format you used for your
mailboxes.db when you compiled cyrus. it SHOULD be skiplist, if it's
not, then that could be the problem.

I bet most of those do cache the folder listings on their end. Horde can
do this now in the horde 3/imp 4 release, but you have to enable it in
the IMP configuration.  Also seting up the imapproxy
(http://www.imapporoxy.org) for any webmail app would be a good thing.

It's the standard IMAP4rev1 command to list folders.. there's only two
ways to get a folder listing, list and lsub.
