[FUG-BR] SMTP reescrevendo o "From"

[Edilson Azevedo]

Caros,

 Ao receber-mos uma mensagem de alguns domínios externos (telefonica, por
exemplo), nosso servidor reescreve o cabeçalho e troca o domínio embratel
para nosso domínio interno. A mensagem chega, mais ao respondê-la,
obviamente dará erro.
