Acabei de seguir este excelente tutorial sobre configuração de um servidor de correio com o Postfix / Dovecot / etc .
Eu passei por isso e posso enviar e-mails bem. O domínio que estou usando é jonah.name . No entanto, não consigo receber emails de emails externos ou de outras caixas de correio internas. Se eu tentar enviar um e-mail para um usuário, recebo um e-mail "E-mail devolvido não enviado ao remetente", informando que o usuário é desconhecido . Isso é o que aparece em /var/log/mail.log :
