Honestly, you should not have an MX server outside of your control.
If your server is routinely down for several days, then you shouldn't be
running your own server.
OK. Let's assume I don't have an MX Backup. Then all 30k+ attempted spam
deliveries would have come straight to me. They would all have failed,
initially because of unknown recipient, then, when I added them to the
access list, because of an denied sender. What is the most efficient way
of blocking these messages? Can they be blocked earlier than
smtpd_sender_restrictions?
