[Dovecot] converting from courier-imap

[Emily]

Hello. I apologize if there is a simple answer to this question, but I 
haven't been able to figure it out. Our people use various clients (pine 
4.50 with maildir patch, eudora, messenger, outlook, squirrelmail), and 
all of them work with courier-imap. But I've become very interested in 
dovecot after reading about it, so I'm trying it out on another server. 
The results are mixed.

Strangely enough, squirrelmail 1.4.1 works wonderfully. For some reason, 
it duplicates Sent, Drafts, and Trash, but I deleted the duplicates and 
it was fine. Mozilla messenger is also fine, but with the same 
duplication of those special folders. Everything seems nice and fast.

But some of our users still cling to pine, which works with courier-imap 
using these three lines in .pinerc:
inbox-path={our.server.edu/ssl/novalidate-cert/user=emily}INBOX
default-fcc={our.server.edu/ssl/novalidate-cert/user=emily}INBOX.Sent
folder-collections="IMAP Folders" 
{our.server.edu/user=emily/ssl/novalidate-cert}INBOX.[]

On the test server I'm using dovecot-0.99.10 compiled against 
openssl-0.9.7b in Redhat 9.

This pine configuration worked in courier, but when I try pine with 
dovecot, I can't see any folders under "Folder Collection" other than 
those special three (Drafts, Sent, Trash). I'm sure there's just 
something I'm doing wrong, but I couldn't find anything in the dovecot 
list archives. I would appreciate any advice on what I'm doing wrong in 
getting pine to see the whole collection.

Thanks,
