[Dovecot] Mail.app help

[Mike Garfias]

I'm having a problem with Mail.app and imap folders.  I've got a new install
of dovecot 1.0beta2, and am only experiencing this problem with Mail.  Mutt
works as expected, as well as thunderbird.

When I create a folder using Mail.app, it is written to
~/Maildir/.INBOX.newfolder, which would be fine, if I wasn't telling
everything that I wanted no prefixes.  If I move that folder to
~/Maildir/.newfolder, Mail.app can no longer see it, but mutt and thunderbird
can.  Thunderbird _CAN_ see the folders created as .INBOX.Folder, and even
shows it as a subfolder of my inbox, but Mutt completely refuses to see it.

Any ideas what I'm doing wrong here?
