We are running Dovecot 2.0.12. It runs on only one server and /var/mail is local where all the INBOX's are stored. Users other IMAP folders are NFS mounted on the server.

I know this error message has been around a long time. Should we still be seeing it on 2.0.12 with a local /var/mail. Perhaps the message is misleading and really complaining about folders other than INBOX that are NFS mounted.
Our config has
dovecot.conf:mail_nfs_index = no dovecot.conf:mail_nfs_storage = yes
With just one Dovecot server you don't need mail_nfs_storage=yes setting. Just set it to "no" and the error disappears.
Also, does the flush error messages have any real consequences? My understanding is that the rmdir is meant to fail, just to force a flush.
Yeah, nothing breaks, just extra logging.
