This functionality already exists in smtpd. There is no need to duplicate
this in postscreen.
Postscreen's purpose is to keep zombies away so that you can keep
using the existing smtpd features.
It is not a scoring system that makes a decision at the end.
Instead, postscreen makes the decision as early as possible.
