Our backup MX is not filtered (mailhop.org), and probably can't be
changed either.  We have another server colacted on a big ISP
that might make a good candidate for a backup MX, where we'd replicate our
current mail filtering configuration.  In the meantime, we've disabled
the backup MX, in order to establish a baseline.  After that, we might
try nolisting to get a feel for how well that works.
