I have stood up a new test mail server as an upgraded version of my existing
mail server.
I have been fairly consistently getting two types of error messages.
I'm thinking they may be related permissions issues, but I can't figure
out what their problem is.

Oct  4 12:45:47 digory dovecot: imap(guenther): Error: file_dotlock_open()
failed with file /home/guenther/mail/ForUs/.imap/Home/dovecot.index.log:
Resource temporarily unavailable


Oct  4 12:46:16 digory dovecot: imap(guenther): Error:
file_dotlock_open(/home/guenther/mail/ForUs/PCS/.imap/PCS
misc/dovecot.index.log) failed: Permission denied (euid=500(guenther)
egid=500(guenther), access(/home/guenther/mail/ForUs/PCS/.imap/PCS
misc/dovecot.index.log, 4) failed: No such file or directory)

Here are my specifics:

OS:  CentOS 6.4 - 2.6.32-358.11.1.el6.x86_64
MailScanner: 4.84.6
Postfix: 2.6.6
DoveCot: 2.2.4
NFS v4  (both the mail spool and /home are NVS v4 mounts to file server)

Here are the non-default settings:
