I'm trying to enable postfix auth. I'm editing the this section from /etc/dovecot/conf.d/10-master.conf
# Postfix smtp-auth
unix_listener /var/spool/postfix/private/auth {
mode = 0666
user = postfix
group = postfix
}
But after I restart dovecot I get this error:
Starting Dovecot Imap: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-master.conf line 88: Unknown setting: unix_listener
