[Dovecot] Is dovecot NFS safe?

[Adam Shand]

I'm migrating our mailserver from cyrus 2.0 to Postfix and Dovecot.

We're using maildirs delivered to /var/maildir, which is mounted via NFS 
from a Netapp.  My understanding was that maildir was completely happy 
in an NFS environment but I've seen a couple messages here recently 
which mention the dovecot index files not being NFS safe.

Are their any caveats or gotcha's that I need to be aware of?

Thanks,
Adam.
