Indeed. My plan is to defer all mail sent to the secondary. In itself, that
might stop some spam. I can then have the system look at those IPs which hit
the secondary before the primary. Those will be subject to other anti-spam
approaches (not blocking, but e.g. putting delays on them).
So, if you're legit but confused you'll still get mail through, just more
slowly than you otherwise might have.
Cheers,
Alun.
