[imp] Missing Folders

[Mufit Eribol]

I have horde horde-3.0.2, imp-h3-4.0.1 and ingo-h3-1.0 installed on my 
Fedora C3 local server. imp is communicating well with my remote pop3 
server.

The problem is I have just the INBOX folde in IMP. Where are the sent, 
draft messages folders? There is no a button "Folders" on the IMP menu. 
Is it due to I use pop3, not imap on the remote server? Or some other 
configuration issue that I missed?

Thanks for any hints.
