IMAP errors

[mailbox@stanfield.net]

I am having a problem with IMAP/dovecot/squirrelmail on Fedora 7. I 
googled and found similar problems, but none of them helped me fix it. 
I am using Maildir, so I think it has to do with the squirrelmail setup 
for Folders. According to all the posts though, I just need to make 
sure to specify dovecot and that Default Folder Prefix is blank. Still 
no luck though. Does anyone have an idea what I might check. The 
location of the Sent folder is Maildir/.Sent.
