See above. (^-^)

Not with Postfix internal methods. What you can do though is to set
smtpd_hard_error_limit to a low value. Each error from the client raises
the counter until the limit is reached and the client is disconnected.

You desire could only be done with a policy server. Though I advise
against this.
