You can combine these two ideas: slow down everthing a little, or 4xx it,
but when you do accept mail from a host and it turns out not to be spam
then you auto-whitelist it.

Ian Jackson has written software to do this:
although A) it's written in tcl and B) it's by default a little too
paranoid for most people. SAUCE maintains an "annoyedness" factor for each
host which starts out as "suspicious" and increases if you send it
RFC-compliant ham, and worsens if you send spam or don't have working
reverse DNS. The more annoyed it is, the more heavily you will be
