Postfix behavior is completely deterministic.
- If a milter rejects an SMTP request then Postfix DETERMINISTICALLY
rejects that SMTP request (with a 5XX status).
- If a milter fails to respond, then Postfix DETERMINISTICALLY
replies corresponding to the the milter_default_action (default:
tempfail the request with 451 4.3.5 Server configuration problem).
I can't see where the text suggests that Postfix will enter an undefined state.
