service {
   chroot =
   client_limit = 1
   drop_priv_before_exec = no
   executable = lmtp -L
   extra_groups = $default_internal_group
   group =
   idle_kill = 0
   privileged_group =
   process_limit = 0
   process_min_avail = 0
   protocol = lmtp
   service_count = 0
   type =
   unix_listener {
     group = postfix
     mode = 0600
     user = postfix
     path = /var/spool/postfix/private/dovecot-lmtp
   }
   unix_listener {
     group =
     mode = 0666
     user =
     path = lmtp
   }
   user =
   vsz_limit = 18446744073709551615 B
   name = lmtp
}

I assume the second unix_listener stanza is where the other entry  
comes from, but I haven't a clue where it is getting defined.

I'll keep looking.

Thanks.
