Dai galerinha, ontem meu servidor de email se tornou um zumbi enviando mais de 44000 emails ou seja endoido tudo....
Dai olhando os logs vi que uma conat estava sendo usada usuario@meudominio.com.br desativei essa conta e resolveu essa parte do problema,,, porem olhando os logs agora estão sendo inundados por entradas como esta, isso representa um risco posso fazer algo?
ja bloqueei uns 50 ips e não adianta.
