Postfix / Amavis 451 4.3.0: Falha de pesquisa temporária

1

Estou tentando configurar um servidor de postfix para evitar spam / malware. O servidor deve rejeitar o e-mail recebido, que é suspeito, caso contrário, envie-o para os servidores de e-mail reais que estão listados em transport_maps. Quando tento testar minha configuração com o telnet, aparece o seguinte:

root@localhost:~# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 spamfilter.local ESMTP Postfix (Debian/GNU)
HELO localhost
250 spamfilter.local
MAIL FROM: <[email protected]>
250 2.1.0 Ok
RCPT to: <[email protected]>
451 4.3.0 <[email protected]>: Temporary lookup failure

Isso se aplica mesmo ao postmaster @ localhost.

main.cf (comentou "check_policy_service inet: 127.0.0.1: 10023" porque também há greylisting, que desabilitei durante o teste):

Parece que, talvez, você tenha esquecido de criar a tabela de mapas de transporte real e / ou o banco de dados aliases usando as informações que você definiu nas configurações.

Tente resolver este problema com os seguintes comandos:

sudo postmap /etc/postfix/transport_maps
sudo postfix reload

ou

newaliases
sudo postfix reload
