Courier has public folders, sorta, but not in the standard usage that IMAP 
users expect.  It won't store message status flags like read, replied, 
forwarded, etc on an individual basis.  Also, rather than ACLs to connect 
users to folders with particular permissions, the users need to be configured 
with the appropriate folder/file permissions on the Maildirs that are holding 
those public folders.

So yes, courier has a public folder implementation, but it's not a very good 
one.  Ultimately, the thing that makes Courier cool in my eyes (Maildir) is a 
very limiting factor when it comes to public folders.
