Usei como base o seguinte tutorial:
http://www.howtoforg...il-ubuntu-10.10
O problema:
Não consigo receber emails através do postfix para usuários virtuais, mas consigo enviar! Quando tento logar através do pop3/imap occorem erros.
Bom abaixo seguem os testes de conexões, arquivos de log, aquivos de configuração, e apresentação dos erros. Peço desculpas pois o post vai ficar um tanto quanto extenso.
