Configurando o Postifix

Esta é a parte final deste How-To, é a configuração final do postfix, será basicamente, ligando o Postfix ao Cyrus-Sasl e a base de dados, basicamente, abaixo serão mostrados os arquivos do diretório /usr/local/etc/postfix, todos eles devem estar presente, as únicas alterações a serem feitas é o nome do usuário e senha da base de dados nos arquivos de ligação com o MySQL.

pronto, tudo deve estar funcionando.
