Postfix Spam

[Leandro Anjos <anjosmoura@yahoo.com.br>]

Bom dia Srs.

Eu tenho em minha empresa um servidor de e-mail com postfix.
Esta semana mudamos de ip externo e reconfiguramos o DNS.
Até ai tudo bem.

Porém deste então minha fila de e-mail fica lotada e com e-mails de remetente e destinário desconhecidos.

exemplo :
