This is a problem with ' ' sorting before '.'.  There is a known problem 
in that Cyrus uses the ASCII sort order to compare mailbox names, but 
wants the hierarchysep character to sort first, which it doesn't in 
ASCII.  This is something that I need to fix.

The sort-term solution is to tell your users to not use spaces in 
mailbox names.
