What are you doing with its Postmaster account? I personally like to have
separate Postmaster accounts for my primary and both secondary MXes on the
theory that  if I'm regularly checking mail on those secondaries I know that
they're up and running against the day I may need 'em.

I also tend to use more restrictive blacklists on my secondary servers than
on the primary. Since I should be receiving less mail on them, I don't care
that more RBLs take longer, for instance; I'm also more tolerant of
collateral damage, since there's a much smaller percentage of legit mail
that will pass through those secondaries.

In fact, I'm in the process of migrating my secondary servers to Postfix
because it will allow me more customizable anti-spam filters than SIMS
provides (plus it will run on OS X without classic, which allows me to
consolidate some of the swarm of single-purpose boxes now decorating my
server room).
