Boa tarde Srs,
Tenho a diretiva para proibir que seja forjado meu domínio, vejam:
# vi main.cf
smtpd_recipient_restrictions = permit_mynetworks,
reject_unauth_pipelining,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
reject_unauth_destination,
check_sender_access hash:/etc/postfix/dominios
dentro do arquivo dominios tenho meus dominios e tals... tudo funciona...
Porém hoje, tive uma mensagem, como seguinte cabeçalho recebido lá no cliente,
vejam:

Em resumo, fiquei surpreso em nao ter bloqueado...
alguém sabe o que pode ter ocorrido, e se for algo que deva ser implementado,
indicar o que pode ser?
Obrigado,
Diego
