I just installed Roundcube on a new server, and I'm noticing a quirk after going through the config and having it connect to my courier imap server.
When you log in, you can only see unread messages listed in the folder list. Folder count shows message 1-40 or 203, and I've verified there was mail in the box by logging in via Outlook Express to port 143. I've already checked to be sure caching was set to false in the main.inc.php file and I've verified this only happens with messages that have been marked as read. If I take a read message, and mark it as unread in OE and refresh in roundcube it shows up until I read it. Once read they won't show up.

Any suggestions?
