[horde] "Other Users" and "Shared Folders"

[Kevin Konowalec]

Where does imp ask for the IMAP List command for "Other Users" and  
Shared Folders"?  I tried to put the latest greatest horde/imp/turba  
into production this morning and it beat the snot out of our IMAP  
server.  On tracing the imap session we see it taking forever to come  
back from asking for "Other Users" and "Shared Folders"... neither of  
which we support.  So how can we stop this from happening?  We  
already figured out to add "INBOX." in the folders field i nthe  
server definition but this is so far eluding me.
