Yep, you could. BUT

1- why let it get to postfix? This is crap that spamd can deal with,

with a bit of scripting help for extra functionality.
2- What concurrency?

We had a mailstorm of backscatter from hundreds of IPs each trying to

send one or two messages. We had over a thousand IPs marked TRAPPED in

spamdb at one time. Postfix would just be rejecting them and filling

its logs.
As far as I'm concerned filling the logs of mailservers that are

backscatter generators is A Good Thing .
