[PLUG] Dovecot Problem

[Michael Barnes]

I'm setting up a mail server on a Raspberry Pi with Postfix and Dovecot.
When I try to start dovecot, I get an error:

# 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf
doveconf: Fatal: Error in configuration file
/etc/dovecot/conf.d/10-director.conf line 30: Unknown setting: userdb {
service { service

Here is the relevant part of the 10-director.conf file (Line 30 is "service
director {)

# To enable director service, uncomment the modes and assign a port.
service director {
  unix_listener login/director {
    #mode = 0666
  }
  fifo_listener login/proxy-notify {
    #mode = 0666
  }
  unix_listener director-userdb {
    #mode = 0600
  }
  inet_listener {
    #port =
  }
}

I honestly know nothing about dovecot. I'm just following a tutorial on
setting up a mail server on an RPi.

Thanks for any ideas.
