I set up a new mailserver with postfix and Dovecot some days ago, everything is working except for Thunderbird not showing any folders.

Evolution shows me all folders.

I migrated from a Courier install using imapsync.

In the filesystem the folders don't have a INBOX in their name, so the tho folders ar called .Folder 1 not .INBOX.Folder 1.

This is the output of dovecot -n:

I don't know why but Thunderbird hadn't subscribed to the folders. I did so and everything works now.
