You need a policy server.

I love this approach btw. NetBSD implemented a blacklist daemon
over a decade ago (ca.) with patches for also postfix, it is now
blocklistd except on FreeBSD where i think it is still red and
yellow. OpenSSH now implemented something that goes into this
direction but is "boxed" and cannot be scripted (afaik, i did not
really look). Ie, that is *only* about failed login (but from the
idea it is right, catching events where they occur, not
textualized, sent via syslog, then parsed as text).
What you want there is not, what you can do is using a policy
server, see README_FILES/SMTPD_POLICY_README.
That file actually contains a perl(1) code snippet which can be
used as a template. (Actually examples/smtpd-policy/greylist.pl:
throw out anything but only play with the $attr{} hashmap.)
