On the client side, it's Linux 2.6.23.16. All attribute cache related
values are at their default, as far as I can tell. The entry in fstab
reads:

nfs-server:/srv/storage /srv/storage nfs rw,nfsvers=3,hard,intr,nosuid,noexec,nodev,noatime 0 0

I just checked again. See below for an example of the logs for one mailbox.
