Estoy intentando configurar mi servidor para recibir y enviar correos. Enviar correos electrónicos no es un problema, pero parece haber un problema al recibirlos. Tengo esta configuración funcionando en mi servidor anterior, pero ahora estoy migrando a un servidor nuevo, en el que está instalado Dovecot 2, la configuración parece fallar. Sigo recibiendo los siguientes registros de errores en /var/log/syslog:

¿Puede esto tener algo que ver con la actualización a Dovecot 2 (actualicé los archivos de configuración)? Postfix está construido con soporte para dovecot, pero no estoy seguro de si esto debe compilarse de manera diferente para la versión 2.
Respuesta1
Dovecot está configurado para escuchar solicitudes de autenticación en private/auth:
unix_listener /var/spool/postfix/private/auth
Sin embargo, le estás diciendo a Postfix que se conecte a una ubicación completamente diferente:
smtpd_sasl_path = smtpd
– de hecho, (casi) le estás diciendo que envíe las solicitudes de autenticación asu propio demonio SMTP, que no los entenderá en absoluto y mucho menos los reenviará a Dovecot.
Cambie la ruta del socket SASL en Postfix a private/auth.
