[Dovecot] Problem with mail_location and INDEX location

HI,

I'm pulling my hair out a little trying to get dovecot to save it's 
index locally rather than in the NFS mount. No matter what I do it seems 
to save the indices in the Maildir on the NFS.

I'm using dovecot 2.0.18 on CentOS 6.3.

The relevant config I'm using:


mmap_disable = no
dotlock_use_excl = no # only needed with NFSv2, NFSv3+ supports O_EXCL and it's faster
mail_fsync = always
mail_nfs_storage = yes
mail_nfs_index = no
lock_method = dotlock

# Mail location and mailbox format.
mail_location = maildir:/%Lh/Maildir/:INDEX=/var/indexes/%Ld/%Lu/



Dovecot runs under the user:group vmail:vmail, and the user has write 
access to those directories.

After restarting dovecot, and logging in via imap, I see the following 
under the Maildir:

Any ideas?

Matt
