Boa tarde pessoal.. Tudo bem?
Aproveitando o email, eu fiz alguns bloqueios no mesmo sentido que o
Aguimar comentou..
Tenho recebido diversos emails de domínios .fun .ltda .de .yin ...etc...
Só que estou tendo um problema com um bloqueio do dominio .de, preciso
liberar o dominio da bayer.com, que por trás tem outros MX..
