Relay aberto para emails do domíno

Olá galera, estou com problema no meu servidor de email a algum tempo, e não tenho conseguido muito sucesso, tenho serviço de postfix+dovecot+saslauth rodando no meu servidor, o problema é que se alguem usa o meu smtp para enviar emails para usuarios do meu domínio esta passando sem exigir autenticação, para outros domínios ele exige autenticação.
se alguem puder me dar uma luz.

amigo, passei pelo mesmo problema

muda isso

smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtp_sasl_security_options = noanonymous


seja feliz

Experimente deixar a macro smtpd_recipient_restrictions dessa maneira:

smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination, reject


good lucky

quando eu coloco desta forma, o postfix rejeita os email enviados, pode ser algum problema de DNS reverso, o meu reverso quem responde é a Embratel.
