Eu tenho trabalhado na configuração do meu servidor de e-mail nas últimas semanas usando postfix, dovecot e mysql. Eu tenho um domínio virtual e algumas caixas de correio virtuais. Usando o squirrelmail, consegui fazer login em minhas contas e enviar e-mails (por exemplo, posso enviar para o googlemail), mas não consigo receber nenhum e-mail - nem do mundo externo nem da minha própria rede. / p>
Eu consigo fazer telnet usando localhost, meu ip privado e meu ip público na porta 25 sem problemas (tentei usando o próprio servidor e de outro computador na minha rede).
Isso é o que recebo em meus registros quando envio um e-mail da minha conta do googlemail para meu servidor de e-mail:

A partir da saída acima, tenho certeza que todos os meus problemas derivam de (falha temporária. Saída de comando: Não é possível abrir o arquivo de log /var/log/mail-dovecot.log: > Permissão negada), mas não tenho idéia porque estou recebendo esse erro. Eu tenho as permissões para esse log definido como os outros logs de email:

O Postfix executará /usr/lib/dovecot/deliver para entregar e-mails e parece que deliver está falhando porque não pode gravar em /var/log/mail-dovecot.log . Não tenho certeza de qual usuário está sendo executado, mas acho postfix , então tente tornar mail-dovecot.log gravável pelo usuário postfix .
