Olá a todos!

Muito obrigado por me receberem nesta comunidade.

Tenho um servidor CentOS 5.6 no qual corre um mail-relay (e outros tantos serviços).

O problema neste momento é que encontro frequentemente nos logs do postfix (/var/log/maillog) tentativas de envio de mails para email@example.com.

>>>>>>>>>>>>>>>>>>> Podem ver um exemplo dos logs de /var/log/maillog:
