O postfix encaminha o e-mail que ele não pôde entregar para o relayhost

1

Quando uma mensagem não pode ser entregue localmente por algum motivo, o Postfix usa o host de reencaminhamento para enviar a mensagem para lá, o que é muito sem sentido. Como posso evitar isso e gerar uma mensagem de erro para o postmaster ou ignorar o erro?
