Se voces poderem me da uma força.
nosso firewall aqui da empresa estava funcionando normal, ate que um dia começou aparecer uns erro no log. Assim nos nao podemos enviar e-mail so recebe-los. Alguem pode dar uma sugestão para que posso corrigir este erro ?
Ja ate verifiquei o dns da embratel se estava errado mais esta ok.
