There is nothing you can do in Postfix if Dovector is misconfigured
to accept and discard mail. If Dovecot reports a temporary error,
Postfix will queue the mail. If Dovecot reports a permanent error,
Postfix will bounce the mail.

Postfix needs no further tuning for sensible behaviour in this
situation. Spend your efforts on making sure the Dovecot
configuration is correct.
