According to this, Postfix invokes check_policy_service at end-of-data.
This requires that Postfix did not block the client, ehlo/helo, sender,
at least one recipient, and the data command.

Also, check_policy_service/postfwd does not inspect email content.
It reports that the end-of-data state was reached, plus some SMTP
session properties.
