Dovecot / Postfix / SASL: Falha na conexão / var / run / dovecot / auth-client: permissão negada

Question

A configuração do Dovecot / Postfix não está funcionando corretamente no meu servidor: depois de várias verificações, eu entendo que

1. Os serviços do imap são operacionais usando clientes locais ou de desktop
2. O postfix está ouvindo e novos e-mails são gravados na fila do postfix
3. A transferência da fila do postfix para as pastas do vmail não está funcionando, enquanto o log do postfix menciona esse erro do recrutador "SASL: Conectar a / var / run / dovecot / auth-client falhou: Permissão negada".

Aqui está minha configuração dovecot.

Se alguém tiver alguma dica ou qualquer coisa, por favor, deixe-me saber que será uma grande ajuda! Obrigado

    

Answer 1

Você define este parâmetro em main.cf

smtpd_sasl_path = /var/run/dovecot/auth-client

Isto diz ao postfix onde caminho o socket unix para conexão SASL.

No entanto, na configuração dovecot, você define que o soquete SASL estava em / var / spool / postfix / private / auth

service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  ...
}

Tente definir smtpd_sasl_path = private/auth e reinicie o postfix.
