Ubuntu 14.04 / iRedMail - Erro SMTP (451): Falha ao adicionar destinatário

Question

Estou enfrentando um problema estranho depois de hoje.

Há meses estou usando o iRedMail 0.9.2 e não tenho nenhum problema. Recebi e enviei e-mail até hoje.

Hoje instalei apt-get install sendmaile tudo parou de funcionar.

Agora não consigo receber e enviar e-mails.

Então, consegui remover o sendmail e reinstalar o postfix, mas agora no Roundcube, quando tento enviar um e-mail, recebo o seguinte erro:

SMTP Error (451): Failed to add recipient "[email protected]" (4.3.0 <[email protected]>: Temporary lookup failure).

Eu removi o sendmail e reinstalei o postfix assim:

sudo apt-get purge sendmail
sudo apt-get install --reinstall postfix
sudo /etc/init.d/postfix restart

Aqui está o que meu mail.log diz:

Você pode me ajudar a resolver esse problema. Acho que tenho uma configuração errada para meu postfix.

Você pode me ajudar a resolver o problema?

Desde já, obrigado!

Answer 1

warning: mysql:/etc/postfix/mysql/virtual_mailbox_domains.cf is unavailable. unsupported dictionary type: mysql

Provavelmente, isso se deve à falta da extensão do postfix que fornece suporte de pesquisa mysql. Na maioria das distribuições/gerenciadores de pacotes o pacote é chamado postfix-mysql, por exemplo:

apt-get install postfix-mysql

Você atualizou os servidores de nomes dos domínios após a mudança? Os domínios são resolvidos para esse novo servidor?
