We limit the inbox to about 15MB (+/- 5MB depending on who you are) via
the lock+move+unlock+inform method.  This may sound draconian but keeps
inbox sizes down, the user knows how to get the moved mail, and all are
generally happy.

We have four two-node Sun V400 clusters typically with 1K users on each
cluster.
