[Dovecot] Fedora Core 2, dovecot, and Outlook Express

[Joe Hartford]

After the aging harddrive in my Redhat 7.2 server died, I decided it
was time to upgrade.  I bought a new harddrive and did a fresh install
of Fedora Core 2.  I've managed to get www, ssh and sendmail
reconfigured, but I'm having a heck of a time with imap.

I first fooled around with cyrus-imapd, and couldn't make head or tail
of it, so I downloaded a fedore core 1 imapd rpm and installed it. 
That almost worked, but I could only see the INBOX.  Next I tried
dovecot.

Via Outlook Express from my winXP box, I can Refresh the IMAP folder
list, and see the INBOX and the sent-mail and saved-messages folders
that were created when I first ran pine.  However, if I try and mark
sent-mail or saved-messages as Visible, I get an "Invalid mailbox
name: saved-message/" error.  And when I try and view the contents of
Inbox, I get "Mailbox doesn't exist: INBOX/".

I tried running evolution on the server, and I could subscribe and
view the INBOX.  But when I try and make a new folder, it gives me a
"Cannot create the specified folder.  Generic error"

I'm hoping I just have something misconfigured, potential due to
messing around with cyrus-imapd and imapd, or perhaps even pine. 
Anyone have any suggestions?  I'm pretty close to giving up on fedora
core 2 and installing core 1, or perhaps mandrake.
